You should carefully consider the risks and uncertainties described below, together with all other information contained in this annual report, before making any investment decision. Any of these risks and uncertainties could have a material adverse effect on Ternium’s business, financial condition and results of operations, which could in turn affect the price of Ternium S.A.’s shares and ADSs.


Risks Relating to the Steel Industry

A downturn in global or regional economic activity would cause a reduction in worldwide or regional demand for steel, which would have a material adverse effect on the steel industry and Ternium.

Steel demand is sensitive to trends in cyclical industries, such as the construction, automotive, appliance and machinery industries, which are significant markets for Ternium’s products and are also affected by national, regional or global economic conditions. A downturn in economic activity would reduce demand for steel products, which would have a negative effect on the steel industry generally and specifically on our business and results of operations. In 2020, governmental measures adopted in response to the COVID-19 resulted in a severe contraction in gross domestic product and steel consumption globally, affecting Ternium’s main steel markets. In 2022, the Russian invasion of Ukraine led to higher commodity and energy prices, contributing to a global decrease in steel consumption. During 2022, 2023 and 2024, high inflation rates and tighter monetary conditions in the United States and Europe contributed to a weaker demand for steel products in these markets. Uncertainty regarding global or regional economic activity remains high. The recent surge in U.S. trade action is creating significant uncertainty in global markets and is expected to affect Mexico’s apparent steel demand until a definitive understanding of the final measures is achieved. For more information on the imposition of tariffs on steel imports into the United States, see “Certain Regulatory Risks And Litigation Risks - International trade actions or regulations and trade-related legal proceedings could adversely affect Ternium’s sales and revenues and the overall business” and for further information on the investment climate and economic activity in Mexico, see “Risks Relating to the Countries in Which Ternium Operates – Mexico - Changes in, or the termination of, current trade agreements between the Mexico and the U.S., and controversies and disputes between the United States-Mexico-Canada Agreement (USMCA) member countries could adversely impact Ternium’s results of operations and net results”.

A protracted fall in steel prices or price volatility would have a material adverse effect on the results of Ternium.

Steel prices are volatile and are sensitive to trends in steel demand and raw material costs, such as steel scrap, iron ore and metallurgical coal costs. Historically, the length and nature of business cycles affecting steel demand and raw material costs have been unpredictable. Steel prices have been significantly fluctuating in response to market trends, costs of raw materials and world events (including, in recent years, the COVID-19 pandemic and international armed conflicts, such as the Russia-Ukraine war). For instance, U.S. prices of hot-rolled coils bottomed in 2020 to $485 per ton, peaked at $2,135 per ton in 2021, and then showed significant volatility during 2022, 2023 and 2024. A protracted fall in steel prices could result in lower revenues, adversely affecting Ternium’s operating results.
7



Furthermore, if raw material costs decline, the resulting reduction in steel production costs would not be immediately reflected in Ternium’s operating results as we would first consume existing inventories acquired prior to such raw material cost decrease (First In - First Out accounting methodology). Similarly, we may be unable to recover, in whole or in part, increased costs of raw materials and energy through increased selling prices on steel products, or it may take much time to do so.

Regional or worldwide excess steel production capacity may lead to unfair trade practices in the international steel markets and/or to intense competition, hampering Ternium’s ability to sustain adequate profitability.

The steel industry is affected by economic cycles, as well as by regional or worldwide production overcapacity. Historically, the steel industry has suffered, especially on downturn cycles, from substantial overcapacity. In the last decade, overcapacity has been particularly severe in China. More recently, there have been several new steel making and steel processing facilities under construction or ramping-up in the United States and Mexico, which could contribute to an excess of steel production capacity in the region. For further information on competition in the Mexican steel market see Item 4. “Information on the Company—B. Business Overview—Competition —Steel—Mexico”.

Excess steel production capacity may require several years to be absorbed by demand and, consequently, may contribute to an extended period of depressed margins and industry weakness. International trade of steel products conducted under unfair conditions increases particularly during downturn cycles and as a result of production overcapacity. Unfair trade practices may result in the imposition by some countries (that are significant producers and consumers of steel) of tariffs, antidumping and countervailing duties, or other trade measures and may cause fluctuations in international steel trade. The imposition of such trade remedies or temporary tariffs on major steel exporters in significant steel producing countries could in turn exacerbate pressures in other markets, including those to which Ternium is exposed as exporters target such other markets to compensate, at least partially, for the loss of business resulting from the imposition of trade remedies or tariffs.

China is the largest steel producing country in the world, accounting for more than half of worldwide crude steel production, and Chinese exports of steel products to many countries, including exports to Europe, the United States and Mexico, have been subject to the imposition of antidumping and countervailing duties and other trade measures. A decrease in steel consumption or an increase in steel production in China, could cause aggressive Chinese steel export offers, exerting downward pressure on sales and margins of steel companies operating in other markets and regions, including those to which we are exposed. For example, in 2023 there was a surge of flat steel product imports in Brazil of approximately 42% compared to 2022, mainly consisting of low-priced steel imports from China, adversely affecting Brazilian domestic steel production. In June 2024, the Brazilian government implemented a one-year quota system under which steel imports above certain quota are subject to a 25% tariff. Despite such measures, imports of flat steel products in Brazil grew an additional 11% in 2024, mainly consisting of low-priced steel imports from China. During 2024, the Brazilian government initiated anti-dumping investigations on imports of cold rolled and coated steel products from China, which are still ongoing. Similarly, a downturn in global or regional economic activity could encourage unfair steel trade practices adversely affecting the steel industry and Ternium’s business and results of operations. For further information, see Item 4. “Information on the Company—B. Business Overview—Regulations—Trade Regulations".

Sales may fall as a result of fluctuations in industry inventory levels or disruptions in Ternium customers’ supply chains.

Inventory levels of steel products held by our customers can vary significantly from period to period, as they either draw from existing inventory or accumulate further inventory in response to market conditions and prospects. As a result, purchased volumes may be irregular. In addition, supply chain disruptions could reduce customer demand for steel products. For example, in 2021, a global disruption in the automotive industry supply chain severely affected vehicle production and, in turn, affected our steel sales due to a global shortage of semiconductors; and in 2023, disruptions in the supply chain of the Argentine industry, due to constraints in the import of raw materials and intermediate goods in a context of tight foreign exchange restrictions, negatively impacted manufacturing activity and, as a result, steel demand in the country. Fluctuations in steel inventory levels and disruptions in customers’ supply chains can temporarily affect the demand for, and price of, steel products and, accordingly, Ternium may not be able to increase or maintain its levels of sales volume or prices.

Intense competition could cause Ternium to lose its market share and adversely affect its revenues.

8


The market for steel products is highly competitive, particularly with respect to price, quality and service. In both global and regional markets, Ternium competes against other global and local producers of steel products, which in some cases have greater financial and operating resources or direct and indirect governmental support. Competition could result in declining margins and reduced shipments. Competitors could use their resources in a variety of ways that may affect Ternium negatively, including by making additional acquisitions, implementing modernization programs, expanding their production capacity or investing more aggressively in product development among others. To the extent that competitors become more efficient, our sales could suffer as operations confront stronger competition and could fail to preserve their current share of the relevant geographic or product markets. In addition, there has been a trend toward steel industry consolidation among competitors, and current competitors in the steel market could become larger competitors in the future. For further information on competition and investments in the steel industry, see Item 4. “Information on the Company—B. Business Overview—Competition.”

Moreover, Ternium and other steel makers compete against suppliers of alternative materials, including aluminum, wood, concrete, plastic and ceramics. In particular, certain customers, such as the automotive industry, are increasing their consumption of lighter-weight materials, such as high-pressure aluminum obtained through die casting, composites and carbon fiber, sometimes as a result of regulatory requirements or government initiatives aimed at transitioning to a lower-carbon economy. Competition from these alternative materials could adversely affect the demand for, and consequently the market prices of, certain steel products and, accordingly, could affect our sales volumes and revenues.

Price fluctuations, shortages or disruptions in the supply of raw materials, slabs, energy and other inputs could adversely affect Ternium’s profitability.

The manufacture of steel products requires substantial amounts of steelmaking raw materials, slabs, energy and other inputs from domestic and foreign suppliers. Ternium’s raw materials and inputs include large quantities of slabs, iron ore, metallurgical coal, pulverized coal for injection, scrap, ferroalloys, refractories, natural gas, electricity, oxygen and other gases consumed in operating blast and electric arc furnaces, as well as downstream facilities. The availability and pricing of raw materials, slabs, energy and other inputs used in our operations are subject to multiple factors, including market conditions, government regulations or intervention, including import controls and international sanctions, allocation by suppliers, interruptions in production, or other events that can affect continuity of supply and prices, such as wars, natural disasters, chronic climate changes, accidents and epidemics.

Purchased slabs are a key component of Ternium’s production process. Industry consolidation and integration of slab making facilities into finished steel products have been reducing the availability of slabs in the global market. For example, in 2023 ArcelorMittal acquired Companhia Siderúrgica do Pecém (CSP), a Brazilian slab maker that used to be a significant supplier of slabs in the international markets. In addition, ArcelorMittal gradually integrated its slab facility in Lázaro Cárdenas, Mexico, with its steel processing facilities in other locations. Furthermore, in 2021 ArcelorMittal started-up a new hot-rolling mill in Lázaro Cárdenas that led to a further integration of its slab facility in that site. Additionally, the wave of trade sanctions imposed by the United States, the United Kingdom, and the European Union, among other countries, following the Russian invasion of Ukraine, against certain Russian institutions, companies and citizens, resulted in a disruption to the global supply of slabs and other inputs consumed in the steel production process. The resolution of the Russian-Ukraine armed conflict and its consequences in the global markets is still uncertain. New international sanctions against Russian steel companies or citizens could result in slab scarcity and/or increases in slab prices in the market, which would have a material adverse effect on Ternium’s business and results of operations.

We have usually been able to procure sufficient supplies of raw materials, slabs, energy and other inputs to meet our production needs; however, we could be unable to procure adequate supplies in the future. Any protracted interruption, discontinuation or other disruption of the supply of main inputs used in our operations (including as a result of strikes, lockouts, sanctions and other trade restrictions, accidents or natural disasters, armed conflicts, worldwide price fluctuations, the availability and cost of transportation, global epidemics or other factors) would result in lost sales and/or lower margins, and would have a material adverse effect on our business and results of operations. For further information related to effects of global events see “A downturn in global or regional economic activity would cause a reduction in worldwide or regional demand for steel, which would have a material adverse effect on the steel industry and Ternium”. For further information related to the consolidation trend in the steel industry see Item 4. “Information on the Company—B. Business Overview—Competition.”

Ternium depends on a limited number of key suppliers.

We depend on a limited number of key suppliers for the provision of certain key inputs. For example, Ternium Argentina and Ternium Brasil purchase iron ore mainly from Vale, a Brazilian company. There is a trend in the industry towards consolidation among suppliers of raw materials, slabs and other inputs. We have entered into long-term contracts for the supply of some (but not all) of our principal inputs and expect that such agreements will be maintained and, depending on the circumstances, renewed. However, if any key supplier fails to deliver, or if existing contracts cannot be renewed in the future, or if applicable regulations or sanctions limit or prohibit purchases from certain suppliers, we could face limited access to certain raw materials, slabs, energy or other inputs, or could be subject to higher costs and delays resulting from the need to obtain our input requirements from other suppliers.

Risks Relating To Ternium’s Business and Growth Strategy

Past or future acquisitions or other significant investments could have an adverse impact on Ternium’s operations or profits, and Ternium may not realize the benefits it expects from these business decisions.

A key element of Ternium’s business strategy is to identify and pursue growth-enhancing opportunities. As part of that strategy, Ternium regularly considers acquisitions, greenfield and brownfield projects and other significant investments. Since its formation, Ternium has acquired and made significant investments in steelmaking and steel processing assets and businesses in Argentina, Brazil, Colombia, Venezuela, Central America, Mexico and the United States, including the acquisition of Mexican steel companies Hylsamex and Grupo Imsa (now Ternium Mexico), the acquisition of the then main integrated producer of flat steel in Argentina, Aceros Paraná (which then merged with Propulsora and other three steel industry companies and is now Ternium Argentina); the purchase of Brazilian steel slab producer CSA, and the acquisition of a participation in the control group of Usiminas, Brazil’s largest flat steel producer. In addition, the company built a new industrial center in Pesquería, Mexico, and is currently advancing with a new expansion plan, the largest in the company’s history, consisting of new steelmaking and new steel processing facilities in this industrial center and new port facilities for raw material handling in Brownsville, Texas. For information on significant investments, see Item 4. “Information on the Company—B. Business Overview—Our Business Strategy and —Capital Expenditure Program”.

Each acquisition, investment and growth project depends on market and financing conditions. We must necessarily base any assessment of potential acquisitions or organic investments on assumptions with respect to operations, profitability and other matters that may subsequently prove to be incorrect. Our acquisitions or other investments may not perform in accordance with expectations and could have an adverse impact on our operations and profits. For information on additional risks related to significant investments, see “Ternium’s strategic growth projects could be delayed, the cost of those projects could increase, or Ternium’s competitiveness could be affected, if the operations of certain suppliers of heavy equipment are disrupted by geopolitical risk, adversely affecting Ternium’s growth opportunities and profitability”.

In addition, we may fail to find suitable acquisition targets, or to consummate our acquisitions under favorable conditions, or to successfully integrate any acquired businesses into our operations, realize expected synergies or accomplish the business objectives that were foreseen at the time of deciding any such investment. Moreover, Ternium may also acquire, as part of future acquisitions, assets unrelated to its business, and we may not be able to integrate them or sell them under favorable terms and conditions. Integration of any acquired businesses would require a significant amount of time and resources from management and employees. Finally, the existence of other minority shareholders at any acquired company, including Usiminas and its subsidiaries, could delay or prevent us from completing our strategy or fully maximizing our combined competitive strengths. For further information, see “Risks Relating to the Structure of Ternium S.A. - Existence of other shareholders in Ternium S.A.’s subsidiaries and associates could delay or prevent us from completing our strategy.” These risks could have an adverse impact on the ongoing business and a material adverse effect on our financial condition and results of operations.

Acquisitions may be subject to challenges or investigations by governmental authorities, including antitrust and consumer-protection authorities. The costs of complying with authorization or investigation procedures may be significant. Also, antitrust authorities are looking very closely at the effects of acquisitions and may deny authorizations, impose conditions that may result in significant costs or deprive Ternium from the advantages and expected synergies of acquisitions, or initiate investigations upon challenges brought by third parties. Challenges to acquisitions or other investments, and failure to obtain, or conditions imposed for the granting of, authorizations may block or delay transactions, which could have an adverse effect on our financial condition and results of operations.

The construction of Ternium’s new steel slab facility in Mexico could be delayed and its cost could increase, if the operations of certain suppliers of heavy equipment are disrupted by geopolitical risk or our commercial relationship with them is otherwise affected, adversely impacting Ternium’s growth opportunities and profitability.

We are building new steel making facilities in our industrial center in Pesqueria and new port facilities for raw material handling in Brownsville, Texas, as part of our plan to advance the continued integration of our industrial system and reinforce our position as a leading steel supplier in the region, in a market that demands differentiated products, focusing on operational efficiencies and long-term opportunities in North America.

The project is expected to be completed in 2026. For information on significant investments, see Item 4. “Information on the Company—B. Business Overview—Our Business Strategy and —Capital Expenditure Program”.

The proper execution of this project relies, among other factors, on timely manufacturing, delivery and commissioning of the equipment ordered, or to be ordered, for these new facilities. The imposition of government requirements, sanctions or tariffs as a result of trade or other geopolitical conflicts may prevent some of our suppliers of heavy equipment from shipping the equipment, or may result in shipping delays, or may limit our purchases or payments of products to such suppliers, and we may not be able to promptly procure such equipment from an alternative facility of such supplier or from other suppliers, or we may be required to purchase equipment at increased prices, which could result in increased expenses and/or a delayed execution of our growth plans, adversely affecting Ternium’s profitability and net worth.

Ternium may be required to record a significant charge to earnings if it must reassess its goodwill, other amortizable intangible assets, investments in non-consolidated companies, property, plant and equipment and other long-lived assets.

In accordance with IFRS, management must test our assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Assets subject to testing include goodwill, intangible assets, investments in non-consolidated companies, property, plant and equipment and other long-lived assets. In addition, management must test for impairment goodwill at least once a year, whether or not there are indicators of impairment. IFRS requires Ternium to recognize a charge in an amount equal to any impairment.

We review periodically the recoverability of our investments. As of December 31, 2024, goodwill in connection with our Mexican subsidiaries amounted to $662.3 million and the carrying value of our investment in non-consolidated companies amounted to $468.5 million. If Ternium’s management determines in the future that the goodwill from its acquisitions, its investments in non-consolidated companies or the carrying value of its property, plant and equipment and other long-lived assets are impaired, Ternium will be required to recognize a charge against earnings, which could materially adversely affect our results of operations and net worth. In the past, Ternium recorded impairment charges several times. For example, as of December 31, 2012, September 30, 2014, December 31, 2015, and September 30, 2022, we wrote down our investment in Usiminas by $275.3 million, $739.8 million, $191.9 million and $120.4 million, respectively. In the fourth quarter of 2024, we recorded a $32.4 million impairment charge of certain mining assets from Las Encinas S.A. de C.V. ("Las Encinas"). See note 4(e)(2) “Accounting Policies – Intangible Assets – Mining Assets” to our consolidated financial statements included in this annual report, and for information on impairments recorded by Ternium, see note 4(f) “Accounting Policies – Impairment” of our audited consolidated financial statements included in this annual report.

In addition, in July 2023, Ternium increased its participation in Usiminas control group and began to consolidate Usiminas. As a result of this transaction, Ternium recorded a $1.1 billion non-cash net loss composed of (i) a loss of $935 million corresponding to items recognized as of the acquisition date, in “Other Comprehensive Income” related to Ternium’s previous stake in Usiminas. This negative reserve was mainly related to CTA losses due to the impact on Usiminas valuation of the depreciation, over the years, of the Brazilian Real versus the U.S. dollar, as Usiminas uses the Brazilian Real as its functional currency. As a result of the increase in the participation in Usiminas, items recognized in Other Comprehensive Income related to Ternium’s previous stake in Usiminas were recycled to the results of the period. The resulting $935 million loss was non-cash, had no income tax effects and did not change the value of Ternium’s equity; and (ii) a net loss of $171 million as a result of the purchase price allocation related to the business combination performed in the third quarter of 2023 and the remeasurement of Ternium’s previous stake in Usiminas. For further information, see note 3 “Acquisition of Business—Increase of the participation in Usiminas control group and new governance structure of Usiminas”, to our consolidated financial statements included in this annual report.

Any further write-downs to or revaluation of Ternium’s assets or investments could have a material adverse effect on Ternium’s results of operations or net worth.

If Ternium does not comply with laws and regulations designed to combat corruption in countries in which it sells its products, it could become subject to fines, penalties or other sanctions and to private lawsuits and Ternium’s sales and profitability could suffer.

We conduct our business in certain countries known to experience governmental corruption. Although Ternium is committed to conducting business in a legal and ethical manner in compliance with local and international statutory requirements and standards applicable to its business, there is a risk that employees, representatives, associates or other persons may take actions that violate applicable laws and regulations that generally prohibit the offering or making of improper payments to any individual, including government officials, for the purpose of obtaining an undue benefit or undue advantage or keeping business, including laws relating to the 1997 Organization For Economic Co-operation and Development (OECD) Convention on Combating Bribery of Foreign Public Officials in International Business Transactions such as the U.S. Foreign Corrupt Practices Act and other anti-corruption laws adopted by the main countries in which we operate (including Mexico, Argentina, the United States, Brazil and Colombia), which impose strict criminal liability on companies for corrupt practices undertaken by their employees or representatives. In addition, we cannot give any assurance that we will detect all illegal activity that may have been conducted before the acquisition at any acquired business.

Labor disputes could result in work stoppages and disruptions to Ternium’s operations negatively impacting our results.

A substantial majority of Ternium’s employees at its manufacturing subsidiaries are represented by labor unions and are covered by collective bargaining or similar agreements, which are subject to periodic renegotiation. Strikes or work stoppages could occur prior to or during the negotiations leading to new collective bargaining agreements, during wage and benefits negotiations or, occasionally, during other periods for other reasons. Ternium’s subsidiaries could also suffer plant stoppages or strikes if they were to implement cost reduction plans. From time to time, we take measures to increase competitiveness; none of the measures taken in the past have resulted in significant labor unrest. However, we cannot assure that this situation will remain stable or that future measures will not result in labor actions against Ternium companies.

Labor conflicts in Mexican mining companies remain a concern, in some cases stemming from disputes over profit-sharing, known as PTU (Participación de los Trabajadores en las Utilidades), after the introduction in recent years of certain regulatory reforms. While Ternium’s mining companies have not been subject to strikes, we cannot rule out the possibility of labor conflicts if profitability were to decrease and PTU-related payments to weaken.

Any future stoppage, strike, disruption of operations or new collective bargaining agreements could result in lost sales and could increase our costs, thereby affecting our results of operations. For further information on the geographic distribution of employees, see Item 6. “Directors, Senior Management and Employees—D. Employees”.

Changes in exchange rates or any limitation in Ternium’s ability to hedge against exchange rate fluctuations could adversely affect Ternium’s business and results.

Our operations expose us to the effects of changes in foreign currency exchange rates and changes in foreign exchange regulations. A significant portion of Ternium’s transactions is carried out in currencies other than the U.S. dollar. As a result of this foreign currency exposure, exchange rate fluctuations impact Ternium companies’ results as reported in their income statements and statements of financial position. In the ordinary course of business, Ternium companies may see fit to enter into exchange rate derivatives agreements to manage exposure to exchange rate changes. Future regulatory or financial restrictions in the countries where we operate may reduce our ability to manage our exposure to exchange rate fluctuations, and thus could cause an adverse impact on our results, financial condition or cash flows. For information concerning the effect of the changes in exchange rates on our business and results, see Item 5. “Operating and Financial Review and Prospects—Overview”.

In addition, Usiminas uses the Brazilian real as its functional currency. Accordingly, any fluctuation of the BRL exchange rate will impact non-BRL balances’ exposure in Usiminas’ balance sheet and, therefore, impact Ternium’s balance sheet and results of operations. Additionally, as our participation in Usiminas is denominated in Brazilian reais, any fluctuation in the BRL/$ exchange rate will affect Ternium's balance sheet with impact in the statement of comprehensive income as currency translation adjustment.

Cyberattacks could have a material adverse impact on Ternium’s business and results of operations.

12


For purposes of carrying out its operations, Ternium relies heavily on information systems; and digital technologies have an increasingly significant role across the business. Although we devote significant resources to protect our systems and data, and continually monitor external developments and available information on threats and security incidents, we have experienced and we expect to continue to experience varying degrees of cyber incidents in the normal conduct of business, and also occasionally experience sophisticated cybersecurity threats including actual or potential unauthorized access to data and systems, loss or destruction of data, computer viruses or other malicious code, phishing, spoofing and/or other cyberattacks. Cybersecurity threats and incidents often arise from numerous sources, many of which fall beyond our control, such as fraud or malice from third parties, including fraud involving business email, failures of computer servers or other accidental technological failure, electrical or telecommunication outages or other damage to its property or assets.

Cybersecurity threats and incidents, such as phishing attacks, attempts to compromise user credentials, attempts to compromise firewall infrastructure, fake websites, impersonation and whaling, continued to increase throughout 2024. The sophistication of these attacks also grew at a fast pace. Microsoft has informed that the manufacturing sector was the industry most subject to ransomware attacks in 2024. Experts agree that cyberattacks are increasing in sophistication and frequency and call for a global response to cybersecurity threats, and regulators are placing increased focus on cybersecurity and its effects.

Cyber ecosystem risk is becoming more problematic. According to the World Economic Forum’s 2024 Global Cybersecurity Outlook, the gap between organizations that are cyber resilient and those that are not is widening, which is concerning in light of the interconnected nature of the cyber ecosystem. According to data set forth in such report, 41% of the organizations that suffered a material incident in the past 12 months attributed the incidents to a third party, and 54% of the organizations have insufficient visibility into the vulnerabilities of their supply chain. This raises a significant concern as even resilient companies may be exposed to the vulnerabilities of third-party suppliers, service providers or clients.

In addition, emerging technologies, like generative artificial intelligence (AI), which are becoming available more widely and faster, are expected to exacerbate cyber resilience challenges. Approximately half of executives surveyed at the 2024 World Economic Forum’s annual meeting on cybersecurity stated that advances in adversarial capabilities (phishing, malware, deepfakes) present the most concerning impact of generative AI on cybersecurity concerns.

During 2024, we have not experienced any incidents impacting business-critical IT systems.

In this context, we continue to seek to improve cybersecurity controls, processes and procedures to monitor, detect, evaluate and respond to hacking, malware infection, cybersecurity compromise and other risks. In addition, we carry out cybersecurity awareness and ethical phishing campaigns aimed at protecting us against cyberthreats. Given the rapidly evolving nature of cyber threats, there can be no assurance that the systems and measures that we have put in place to prevent or limit the effects of cyber incidents or attacks and the mitigation actions adopted in connection with such attacks will be sufficient to prevent or detect such incidents or attacks, to avoid a material adverse impact on our systems. While we continue to attempt to mitigate these risks, there remains the risk of additional known or unknown threats, including theft, misplacement or loss of data, programming errors, employee errors and/or dishonest behavior that could potentially lead to the compromising of sensitive information, improper use of our systems or networks, as well as unauthorized access, use, disclosure, modification or destruction of such information, systems and/or networks.

If Ternium’s systems and measures for protecting against cybersecurity risks are circumvented or breached, this could result in disruptions to its business and operations (including but not limited to, defective products, production downtimes or loss of productivity), access to financial reporting systems, the loss of access to critical data or systems, misuse or corruption of critical data and proprietary information (including intellectual property and customer data), as well as damage to our reputation with customers and the market, failure to meet customer requirements, customer dissatisfaction and/or regulatory fines and penalties (including for inadequate protection of personal data and/or failure to notify the competent authorities for such breach) or other financial costs and losses.  In addition, failure to adequately and timely monitor and evaluate our hardware and software systems and applications to prevent or manage technology obsolescence risks may result in increased costs, operational risk of service failure, and the loss of technology competitiveness and reputation.

In addition, given that cybersecurity threats continue to evolve, we may be required to devote additional resources in the future to enhance its protective measures or to investigate and/or remediate any cybersecurity vulnerabilities. Ternium does not currently maintain cybersecurity insurance and the insurance it carries for property damage and general liability may not protect Ternium from damages derived from cyber events. Moreover, any investigation of a cyberattack would take time before completion, during which Ternium would not necessarily know the extent of the actual or potential harm or how best to remediate it, and certain errors or actions could be repeated or compounded before duly discovered and remediated (all or any of which could further increase the costs and consequences arising out of any cyberattack).
13



Furthermore, in response to the increase in the number and sophistication of ransomware attacks, U.S. and other regulatory agencies have implemented regulations to prevent victims from making ransomware payments and to deter third parties from facilitating or processing such payments to cyber actors. This would constrain our ability to deal with ransomware attacks, should they occur.

For information regarding Ternium’s cybersecurity risk management and strategy, see Item 16K. “Cybersecurity”.

The physical risks resulting from climate change, including extreme weather conditions and shifts in weather patterns may adversely impact Ternium’s business, results of operations and net worth.

Ternium’s business has been, and in the future could be, affected by severe weather conditions in areas where operations are carried out, which could materially damage our production facilities and general infrastructure or affect the normal course of business, and result in a material adverse effect on Ternium’s financial results. Extreme weather events and natural disasters, such as hurricanes, cyclones, droughts, floods and fires could affect businesses’ operations, workforce, markets, infrastructure, raw materials and assets. For example, in 2024, a power outage caused by a supercell storm disrupted operations at Ternium’s San Nicolás unit in the Buenos Aires province, Argentina. In addition, in the last few years, low water levels at the Paraguay and Paraná waterways disrupted on several occasions the supply of iron ore from Brazil’s iron ore mines in the Pantanal Region (Mato Grosso do Sul state) to Ternium Argentina, requiring from time to time the procurement of higher-cost iron ore from alternative sources and an increase of iron ore inventories.

The communities surrounding our main operation sites in Argentina, Brazil and Mexico are vulnerable to flooding due to extreme weather events. In the past, certain operations in Brazil and Argentina experienced intense rainfall affecting personnel’s access to the facilities. In addition, as Ternium Mexico’s facilities are located at water stressed areas, its operations in the country could be affected by water shortages and/or increased water costs, including as a result of measures taken by local governments to prevent or deal with critical situations caused by severe draughts. For example, in response to severe draughts affecting the metropolitan area of Monterrey in the state of Nuevo León, Mexico, in 2022 the national water authority suspended new freshwater use concessions in the Monterrey area and such concessions remain suspended. In addition, a new bill on management and distribution of water is being discussed in the Mexican Congress as part of a broader effort by the Mexican government to ensure access to water as a human right and improve water sustainability. The Mexican government has also launched a national plan to tackle water scarcity which, among other initiatives, is reviewing water concessions. Although these events did not have a significant impact on Ternium’s operations in the region, we cannot predict future implications of the new water regime to Ternium’s operations in Mexico, or the impact of future similar events, in Mexico or elsewhere, on Ternium’s operations and financial condition.

Extreme weather conditions can also disrupt Ternium’s supply chain. For example, in 2024, Hurricane Beryl disrupted vessel traffic at the Port of Brownsville by diminishing the port’s draught. This negatively affected the supply of slabs to Ternium’s processing facilities in Mexico for approximately two months, which in turn impacted our shipments of finished steel products.

Extreme weather events and natural disasters could result in damage to property, delays in production or shipments and, in extreme cases, death or injury to persons. Any of the foregoing could create liability for Ternium.

Also, chronic climate changes, such as changes in precipitation patterns and rising temperatures and sea levels may result in increased operating costs or capital expenditures, due to supply shortages or damage to facilities, personnel evacuation, increased insurance premiums or reduced availability of insurance, decreases in revenue derived from lower sales, disruption of operations or lower production levels, negative impact on workforce and write-offs and/or early retirement of assets, all of which could adversely affect our financial condition, results of operations and cash flows.

Ternium does not carry business interruption insurance, and the insurance that Ternium maintains for property damage and general liability may not be adequate or available to protect us under such events, its coverage may be limited, or the amount of insurance may be less than the related loss.

Risks Relating to the Mining Activities

Ternium has equity interests in two iron ore mining companies: a 100% interest in Las Encinas and a 50% interest in Consorcio Peña Colorada S.A. de C.V. ("Consorcio Peña Colorada"). Ternium’s mining activities are located in Mexico. In addition, Usiminas holds a 70% equity interest in Mineração Usiminas, a mining company located in Brazil.
14


For information related to the risks of doing business in Brazil and Mexico see “Risks Relating to the Countries in Which Ternium Operates”. In addition, Ternium’s mining activities are subject to the following risks:

Operational accidents and unexpected natural catastrophes may damage the environment, destroy properties and affect production or cause injuries and death, which would adversely impact Ternium’s operations and profitability, and result in material liabilities.

Las Encinas, Consorcio Peña Colorada and Mineração Usiminas carry out extractive, processing and logistical operations. Liabilities associated with such mining activities include those resulting from tailings and sludge disposal, effluent management, iron ore pulp and fines transportation, and rehabilitation of land disturbed during the mining processes. The operations involve the use, handling, storage, discharge and disposal of hazardous substances and bulk material, and the use of natural resources. The iron ore mining industry is generally subject to significant risks and hazards, including environmental pollution, such as spilling or emissions of polluting substances or other hazardous materials; operational incidents, such as open-cut pit wall failures, rock falls, tailings dam breaches or incidents from the storage, transportation or use of explosives; transportation incidents, involving mobile equipment or machinery, slurry pipes and cable transportation; and may also be subject to unexpected natural catastrophes including heavy rain and hurricanes, and high seismic activity affecting our operations in Mexico. This could result in environmental damage, damage to or destruction of properties and facilities, personal injury or death, and delays in production. For example, in January 2022, unusually heavy rains damaged internal roads and drainage systems, affecting Mineração Usiminas’ iron ore production and shipments during that month. By March 2022, Mineração Usiminas was able to fully normalize its operations.

Las Encinas’ and Consorcio Peña Colorada’s tailings dams meet the strictest international seismic standards, but for a tailings dam in which new reinforcements are expected to be completed by Consorcio Peña Colorada by year-end 2025 in order to reduce risks of collapse under a severe earthquake. This reinforcement project follows recommendations arising from stability studies conducted with the assistance of independent consultants. Although Ternium believes that, once completed, Consorcio Peña Colorada’s investment project will further mitigate the risk of incidents or failures at its tailings dam, failures or breaches may still occur prior to, or after, completion of reinforcement works. Furthermore, we cannot guarantee that failures or breaches will not occur in any tailings dam even when meeting the strictest international seismic standards. For further information, see Item 4. “Information on the Company - B. Business Overview - Mining”.

Mineração Usiminas, Las Encinas and Consorcio Peña Colorada may also be subject to claims under federal and local laws and regulations for air pollution, toxic torts, natural resource damages and other damages, as well as for the investigation and clean-up of soil, surface water, sediments, groundwater and other natural resources. Claims for damages and reclamation may arise out of current or former conditions at sites that Ternium owns, leases or operates or at inactive sites that it currently owns, leased-land sites and third-party waste disposal sites. We may be held responsible for other sites in the future. It also could be subject to litigation for alleged bodily injuries arising from claimed exposure to hazardous substances allegedly used, released, or disposed of by Ternium. Environmental damages caused by mining operations may result in costs and liabilities that could materially and adversely affect Ternium’s margins, cash flow and profitability. Third-party claims based on environmental or physical damages may exceed the limit of liability of the insurance policies that Ternium may have in place.

Required governmental concessions could be subject to prior consultation with native communities in Mexico or local communities in Brazil, changes or termination, permits and rights of use and occupancy could be difficult to obtain or maintain and taxes or royalties applicable to the mining industry could increase, all of which could adversely affect Ternium’s mining activities and operating costs.

Mining activities are subject to specific regulations and depend on concessions and authorizations granted by governmental authorities. Increased government intervention or amendments to applicable laws and regulations as well as claims or legal actions from native or local communities or other third parties, may alter the terms pursuant to which mining companies are required to pursue exploration, mining and ore processing activities. Selected mining technologies, additional infrastructure requirements, new taxes and/or royalties may be imposed on mining activities, leading to unexpected capital expenditures, higher costs or a reduction in mineral reserves and/or resources. For example, in 2011, the state of Minas Gerais imposed a rate for the controlling, monitoring and supervision of exploration and mining activities of mineral resources, which determines a fix value per ton sold. In addition, in 2019, the Brazilian federal and state governments issued dam licensing regulations and imposed new conditions in connection with population in the self-rescue zones, including guarantee of stability, expropriation or relocation of the population and de-characterization of dams, which resulted in increased operating costs.

In April 2023, Mexico approved a significant reform to its mining laws. Among other changes, new mining activities were prohibited in certain areas with superficial bodies of water -which are of federal jurisdiction-, and areas declared as natural reserves by federal or local governments.
15


In addition, governmental authorities are authorized to order the removal of existing tailings deposits under certain location or risk circumstances. The new legislation prohibits the use of national waters for the transportation of certain materials, grants to the Mexican geological service exclusive rights to conduct exploration activities, and requires mandatory bidding processes for new exploration and exploitation concessions, limiting concessions to a 30-year duration with 25-year automatic extension and a further 25-year extension following a prior bidding process. Concessions may be revoked on certain grounds, including for failure to initiate or interrupt operations within a specified timeframe or to file a mine closing plan, and accidents may be punished with increased fines and other penalties. In addition, new permits entailing an increase in water consumption in the regions where Las Encinas and Peña Colorada operate are subject to new conditions on water availability. Granting of new mining rights by the federal government are also subject to new water consumption permits based on such new conditions. The reform also regulates royalties and profit sharing with local communities, and mandates consultation processes with native and Afro-Mexican communities. The Supreme Court is reviewing the constitutionality of the new legislation.

For further information on risks, including regulatory risk, relating to our operations in Mexico, see “Risks Relating to the Countries in Which Ternium Operates - Mexico.”

Iron ore exploration and exploitation concessions in Brazil and Mexico as well as water concessions in Mexico may be revoked if the competent government authorities determine that mining companies do not comply with their obligations under the respective concession terms and agreements. Ternium may fail to comply with its commitments regarding certain concessions in Mexico if the security situation in those areas worsens. Furthermore, the exploration and exploitation of mines require the obtention of a right of use and occupancy of the land where the mines are situated. Even though government regulations frequently establish provisions intended to facilitate the granting of such rights, in some cases it may be difficult to reach and maintain agreements with the native or local communities or landowners, or such agreements may be excessively onerous.

If Las Encinas, Consorcio Peña Colorada or Mineração Usiminas cannot secure use and occupancy rights on acceptable terms, their mining activities may be compromised. In addition, Las Encinas, Consorcio Peña Colorada or Mineração Usiminas must obtain, in the normal course of their business, permits to operate new iron ore bodies at the mines and permits for the expansion of Las Encinas’ and Peña Colorada’s tailings deposit capacity and the use of areas for Mineração Usiminas’ stocking piles and filtered waste. If Las Encinas, Consorcio Peña Colorada or Mineração Usiminas are unable to timely obtain required permits or fail with a timely completion of their ongoing projects related to tailings deposit capacity, they may need to alter their mining and/or production plans, which could lead to unexpected capital expenditures, higher costs and/or a disruption of mining activities.

Ternium’s reserve and resource estimates may differ materially from actually recoverable mineral quantities, or its estimates of mine life may prove inaccurate; and market price fluctuations and changes in operating and capital costs may render certain ore reserves and resources uneconomical to mine or cause Ternium to revise its reserve or resource estimates.

Mineral reserves and resources are estimated quantities of ore that Ternium has determined can be economically mined and processed under present and anticipated conditions to extract their mineral content. There are numerous uncertainties inherent in estimating quantities of reserves and resources and in projecting potential future rates of mineral production, including factors beyond our control. Reserve and resource calculations involve estimating deposits of minerals that cannot be measured in an exact manner, and the accuracy of any reserve and resource estimate is a function of the quality of available data and engineering and geological interpretation and judgment. Reserve and resource estimates also depend on assumptions relating to the economic viability of extraction, which are established through the application of a life of mine plan for each operation or project providing a positive net present value on a forward-looking basis, using forecasts of operating and capital costs based on historical performance, with forward adjustments based on planned process improvements, changes in production volumes and in fixed and variable proportions of costs, and forecasted fluctuations in costs of raw material, supplies, energy and wages. These forecasts and projections involve assumptions and estimations that, although Ternium believes are reasonable at the time of estimating its reserves and resources, may change in the future and may fail to anticipate geological, environmental or other factors or events that could make it difficult or unprofitable to mine certain ore deposits.

For further information on Ternium’s resource and reserve estimations see Item 4. “Information on the Company - B. Business Overview - Mining - Iron Ore Mineral Reserves and Resources”.

In addition, our reserve and resource estimates are of in-place material after adjustments for mining depletion and mining losses and recoveries, with no adjustments made for metal losses due to processing. As a result, no assurance can be given that the indicated amount of ore will be recovered from our reserves and resources, or that it will be recovered at the anticipated rates, or that extracted ore will be converted into saleable production over the mine life at levels consistent with its reserve and resource estimates.
16


Reserve or resource estimates may vary in the future, and results of mining and production subsequent to the date of an estimate may lead to future revisions of estimates. Estimates of mine life may require revisions based on actual production figures, changes in reserve and resource estimates and other factors. For example, fluctuations in the market prices of minerals, reduced recovery rates or increased operating and capital costs due to inflation, exchange rates, mining duties or other factors may affect Ternium’s mine life projections. Certain reserves and resources may have a low level of projected profitability. If market price fluctuations or changes in operating and capital costs increase the cost to explore, locate, extract and process iron ore, making it uneconomical to mine, we may be required to lower our reserve or resource estimates. In addition, the mining of certain reserves and resources depend on our ability to reach agreements with local communities, the failure of which could result in a decrease in reserve and resource estimates.

Exploration activities are subject to uncertainties as to the results of such exploration; even if the exploration activities result in the discovery of ore deposits, the effective exploitation of such deposits remains subject to several risks.

Exploration activities are highly speculative, involve substantial risks and may be unproductive. Ternium may incur substantial exploration costs which may not yield the expected results. Failure to find sufficient and adequate ore resources could adversely affect our business. In addition, even if ore deposits are discovered, exploitation activities may be delayed for a long time during which market conditions may vary. Significant resources and time must be invested to establish ore resources through exploration, define the appropriate processes, obtain environmental licenses, concessions and permits (including water usage permits), acquire land, build the necessary facilities and infrastructure for greenfield projects and obtain the ore or extract the metals from the ore. If a project is not economically feasible by the time it can be exploited, we may incur substantial write-offs.

Inability to complete activities required to maintain iron ore and pellets production rates over time could increase Ternium’s steel production cost.

Mining requires continuous investment and activities to sustain production rates such as the design of mining projects, the granting of environmental permits, the development of iron ore reserves and/or tailings dams, and the successful execution of civil works. A large share of Mineração Usiminas’ iron ore reserves and resources are made of an iron ore quality called “Compactos”, which cannot be processed in its current facilities or may be processed at substantially lower rates. Processing “Compactos” iron ore at a rate similar or higher than current processing rates, would require significant capital expenditures in new equipment and facilities. If Mineração Usiminas does not approve or fails to timely develop the project, or fails to obtain the required governmental approvals or to secure key supply agreements on reasonable terms, including for logistics and energy services, Mineração Usiminas’ iron ore shipments will stop once the reserves of other iron ore qualities are depleted, negatively affecting Ternium’s net sales and operating results. On the other hand, if Ternium’s mining companies in Mexico fail to timely carry out the activities required to maintain iron ore and pellet production rates over time, Ternium may be required to substitute self-produced lower-cost iron ore with third-party iron ore to supply its steel operations, with a consequent increase in steel production costs.

Expected costs and capital expenditure requirements for exploration, exploitation or restoration activities may vary significantly and affect Ternium’s financial condition and expected results of operations.

Ternium may be subject to increased costs or delays relating to the acquisition of equipment for the exploration and exploitation of ore deposits, or restoration of exhausted mines. Moreover, we may face increasing costs or capital expenditure requirements related to several factors, including changes in environmental regulations, diminished iron ore reserve grades, deeper pits and operational sections of our mines, iron ore deposits within the pit area that are more difficult to locate or extract, additional maintenance works in dams, tailings and waste piles, and ponds, and increased energy supply requirements that may be difficult to obtain. Adverse mining conditions and other factors related to the operation of the mine and mining facilities during their life cycle, whether permanent or temporary, may lead to a significant increase in projected capital expenditures and costs and may affect our ability to produce the expected quantities of mineral, negatively affecting our financial condition and expected results of operations.

Difficulties or disturbances in the relationship with local communities may adversely affect Ternium’s mining activities and results of operations, and increasing violence and crime in Mexico could result in temporary or even permanent shut down of our Mexican mining operations.

Local communities, groups or individuals living or owning land near the areas where we operate may take actions to oppose or interfere with our mining activities. Even if a community has an agreement in place with Ternium, internal disputes within that community could result in blockades to disrupt our mining operations or iron ore transportation, or in legal proceedings to suspend mining activity.
17


Although we make significant efforts to maintain good relationships with all communities, actions taken by them (or by interest groups within those communities), including requesting the authorities to revoke or cancel concessions or permits, may hamper our ability to conduct mining activities as planned, prevent us from complying with agreements or commitments with the government, or significantly increase the cost of exploring and/or exploiting the mines, thereby adversely affecting our business and results of operations.

Mexico

In the past, Ternium’s mining operations in Mexico faced actions by certain native or local communities demanding higher compensation or other benefits, or seeking to stop mining activities. Although attempted legal actions have not succeeded, under Mexican law judges can preemptively suspend environmental or other permits or concessions and take certain other measures to protect the “ejidos” (land jointly owned by native communities) until the claim is resolved. An adverse court decision suspending or revoking permits, or a blockade or occupation of our facilities, could adversely impact Ternium’s mining activities and results of operations.

In recent years, the security situation in Aquila, where Las Encinas has its main mining operation, worsened, with growing violence in the region being caused by criminal groups seeking territorial control and the exploitation of economic resources. In addition, a long-standing internal dispute between two differentiated groups of a native community prevented the election of community representatives and stirred a great deal of turmoil. In January 2023, two main community leaders went missing, which triggered an investigation by the Attorney General’s office that resulted in the arrest of three suspects. The ensuing crisis forced Las Encinas to keep its main mining operation idled during the first half of 2023. Similarly, the Jalisco area, where Consorcio Peña Colorada operates, is not exempt from the presence of criminal groups and, consequently, security has also deteriorated in such region.

If violence and conflict persist or escalate in the regions where Ternium has its mining operations, Ternium’s mining activities in Mexico may be partially or totally suspended, or even permanently shut down.

Risks Relating To The Structure Of Ternium S.A.

Changes in applicable tax regulations and resolutions of tax disputes could negatively affect our financial results.

Ternium is subject to tax laws in numerous foreign jurisdictions where it operates. The integrated nature of Ternium’s worldwide operations can produce conflicting claims from revenue authorities in different countries as to the profits to be taxed in the individual countries, including disputes relating to transfer pricing. Most of the jurisdictions in which Ternium operates have double tax treaties with foreign jurisdictions, which provide a framework for mitigating the risk of double taxation on Ternium’s results. However, in case double taxation persists, dispute resolution mechanisms developed to resolve such potential conflicting claims are largely untried and can be expected to be very lengthy.

In recent years, tax authorities around the world have increased their scrutiny of companies’ tax filings and have become more rigid in exercising any discretion they may have. In 2015, the OECD proposed a number of tax law changes under its Base Erosion and Profit Shifting (BEPS) Action Plans to address issues of base erosion transparency, coherence and substance. Most of the countries in which Ternium operates have already implemented at least some of those changes within their own domestic tax legislations.

In 2019, the OECD launched a new initiative on behalf of the G20 under the format of a two pillars solution targeting to minimize profit shifting by working towards a global tax framework that ensures that corporate income taxes are paid where consumption takes place (Pillar 1) and targeting to introduce a global standard on minimum taxation (Pillar 2) both combined with new tax dispute resolution processes. This project achieved OECD political consensus in October 2021. Pillar 2 applies to Ternium as from 2024; Pillar 1 is still under discussion.

On January 20, 2025, the United States announced that it would withdraw from the OECD Global Tax Deal and that any prior commitments made by the United States will no longer have any force or effect. The memorandum announcing the withdrawal also directed the U.S. Secretary of the Treasury to develop and deliver to President Trump, within 60 days, a list of protective measures or other options towards foreign countries that are either not in compliance with any tax treaty with the United States or have, or are likely to have, tax rules that are extraterritorial or disproportionately affect U.S. companies.

At the EU level, the European Commission adopted in 2016 its Anti-Tax Avoidance Directive, or ATAD, later on expanded by ATAD 2, which seeks to prevent tax avoidance by companies and to ensure that companies pay appropriate taxes in the markets where profits are effectively made and business is effectively performed. In addition, the European Commission drafted a directive aiming to avoid the use of shell entities (ATAD 3), which is still under discussion. Also, the European Commission adopted in December 2022 another directive to impose a global minimum taxation for multinational companies in the E.U., following Pillar 2’s initiative.
18


This new directive became effective in 2024.

Ternium’s interpretation and application of the tax laws could differ from that of the relevant governmental taxing authority, which could result in the payment of additional taxes, penalties or interest, negatively affecting our profitability and financial condition. Significant uncertainties remain in relation to the potential adoption of the new regulations that might result from evolving initiatives like those launched by the OECD and the EU in relation to international taxation that could impact negatively our financial condition, results of operations and cash flows.

Dividend payments depend on the results of operations and financial condition of its subsidiaries and could be affected by legal, contractual or other limitations or tax changes.

Ternium S.A. is a holding company and conducts all its operations through subsidiaries. Dividends or other intercompany transfers of funds from those subsidiaries are Ternium S.A.’s primary source of funds to pay its expenses, debt service and dividends and to repurchase shares or ADSs.

The ability of our subsidiaries to pay dividends and make other payments to their shareholders will depend on their results of operations and financial condition. If earnings and cash flows of our operating subsidiaries are substantially reduced, Ternium S.A. may not be in a position to meet its operational needs or to pay dividends. In addition, such dividends and other payments could be restricted by applicable corporate and other laws and regulations, including those imposing foreign exchange controls or restrictions on the transfer of money to foreign accounts or the payment of dividends, and agreements and commitments of such subsidiaries. For example, in recent years, Argentine regulations have significantly impaired Ternium Argentina’s ability to transfer dividends abroad and, therefore, Ternium Argentina resorted to the payment of dividends in kind using U.S. dollar-denominated Argentine sovereign bonds. For information on exchange controls in Argentina, see note 30 “Foreign exchange restrictions in Argentina” of Ternium’s audited consolidated financial statements included in this annual report; and “—Risks Relating to the Countries in Which Ternium Operates – Argentina: Exchange controls in Argentina could negatively impact Ternium Argentina’s operations, preventing Ternium from importing raw materials, paying dividends or transferring cash surpluses abroad, as a result of its inability to access the foreign exchange market”.

Ternium S.A.’s ability to pay dividends to shareholders is subject to legal and other requirements and restrictions in effect at the holding company level. For example, Ternium S.A. may only pay dividends out of net profits, retained earnings and distributable reserves and premiums, each as defined and calculated in accordance with Luxembourg law and regulations. In addition, dividend distributions (which are currently imputed to a special tax reserve and are therefore not subject to Luxembourg withholding tax) may be subject to Luxembourg withholding tax if current Luxembourg tax law were to change or if the special tax reserve were to be exhausted.

Ternium S.A.’s controlling shareholder may be able to take actions that do not reflect the will or best interests of other shareholders.

As of February 28, 2025, San Faustin beneficially owned 65.03% of Ternium S.A.’s share capital and Tenaris, which is also controlled by San Faustin, held 11.46% of Ternium S.A.’s shares and voting rights. Rocca & Partners Stichting Administratiekantoor Aandelen San Faustin, (“RP STAK”), holds voting rights in San Faustin sufficient in number to control San Faustin. As a result, RP STAK is indirectly able to elect a substantial majority of the members of Ternium S.A.’s board of directors and has the power to determine the outcome of most actions requiring shareholder approval, including, subject to the requirements of Luxembourg law, the payment of dividends. The decisions of the controlling shareholder may not reflect the will or best interest of other shareholders. In addition, Ternium S.A.’s articles of association permit its board of directors to waive, limit or suppress preemptive rights in certain cases. Accordingly, Ternium S.A.’s controlling shareholder may cause its board of directors to approve in certain cases an issuance of shares for consideration without preemptive rights, thereby diluting the minority interest. See “Risks Relating to Ternium S.A.’s ADSs – Holders of shares and ADSs in the United States may not be able to exercise preemptive rights in certain cases”.

Existence of other shareholders in Ternium S.A.'s subsidiaries and associates could delay or prevent us from completing our strategy.

Ternium S.A. does not own 100% of the interests in certain of its subsidiaries. As of February 28, 2025, 26.0% of Ternium Argentina was held by the Administración Nacional de la Seguridad Social, or ANSeS, Argentina’s governmental social security agency, and 11.4% was publicly held. In addition, 22.7% of Usiminas’ ordinary shares were held by the NSC Group, 4.9% by Previdência Usiminas and 22.9% were publicly held, and 0.6% of Usiminas’ preferred shares were held by the NSC Group and 97.5% were publicly held. Furthermore, Ternium holds a 51% ownership interest in Tenigal (with NSC holding the remaining 49%); a 50% equity interest in Consorcio Peña Colorada (with ArcelorMittal holding the remaining 50%); and a 48% equity interest in Techgen.
19


The existence of other shareholders in these companies could prevent Ternium from taking actions that, while beneficial to the company, might not be beneficial to each relevant subsidiary or associate considered separately. As a result, Ternium could be delayed or prevented from completing its strategy or fully maximizing its competitive strengths.

Risks Relating to the Countries in Which Ternium Operates

Negative economic, political, social and regulatory developments in certain markets where a significant portion of Ternium’s operations and assets are located could disrupt its manufacturing activity, hurt Ternium’s shipment volumes or prices, or increase its costs, thereby adversely affecting its results of operations and financial condition.

Ternium’s results of operations are subject to the risks of doing business in emerging markets, principally in Mexico, Brazil and Argentina, and have been, and could in the future be, affected from time to time to varying degrees by economic, political, social, regulatory and legal developments, such as nationalization, expropriation or forced divestiture of assets; restrictions on production, domestic sales, imports and exports; travel or trade bans; interruptions in the supply of essential energy inputs; restrictions on the exchange or transfer of currency; inability or increasing difficulties to repatriate income or capital or to make contract payments; inflation; devaluation; or other events, including wars and other international conflicts, natural disasters, chronic climate changes and public health epidemics; civil unrest and local security concerns that threaten the safe operation of its facilities and operations; direct and indirect price controls; tax increases and changes (including retroactive) in the interpretation, application or enforcement of tax laws and other claims or challenges; cancellation of contract rights; and delays or denial of governmental approvals. Both the likelihood of such occurrences and their overall effect upon Ternium vary greatly from country to country and are not predictable. Realization of these risks could have an adverse impact on the results of operations and financial condition of Ternium’s subsidiaries located in the affected countries and, depending on their materiality, on the results of operations and financial condition of Ternium as a whole.

Mexico

Ternium has significant manufacturing operations and assets in Mexico and a significant share of its sales are made to customers in this country. In addition, a significant portion of Ternium’s sales in Mexico are directed to the Mexican manufacturing industry, which in turn exports a large share of its production to the U.S. market. Our business could be materially and adversely affected by economic, political, social and regulatory developments in Mexico.

Political, economic and social conditions and government policies in Mexico could negatively impact Ternium’s business and results of operations.

In the past, Mexico has experienced several periods of slow or negative economic growth, high inflation, high interest rates, currency devaluation and other economic problems. Furthermore, the Mexican economy tends to be affected by changes in the economic environment in the United States, including changes to trade conditions. In addition, actions and policies adopted by the Mexican government could have a significant impact on the economy and market conditions affecting Ternium’s operations in Mexico. During 2024, the Mexican Congress approved several constitutional reforms aimed at restructuring the judicial system and increasing state control over key sectors, including energy, telecommunications, and natural resources. This increased regulatory oversight has led to a more unpredictable business environment. A deterioration in Mexico’s economy, a re-emergence of social instability, political unrest, reduction in government spending, increased government intervention, exchange rate and financial market volatility, or other adverse political, economic or social development, could adversely affect our business, results of operations, financial condition or liquidity. Adverse economic conditions in Mexico could also result in higher inflation and interest rates coupled with reduced opportunities for funding or refinancing, reduced domestic consumption of our products, decreased operating results and delays in the completion of ongoing and future capital expenditures.

Energy reforms and the evolving regulatory landscape in Mexico could adversely impact Ternium’s results of operations and net results.

In the last few years, the Mexican government has made various attempts to amend energy rules and regulations impacting the supply and cost of energy.

Since December 2018, the Mexican government has been introducing changes to electricity regulations, including amendments to the Energy Industry Law, or LIE, and a bill to reform the Constitution, which was rejected by the Mexican Congress in 2021.
20


These changes aimed to grant priority to Mexico’s state-owned electric power generation and distribution company, or CFE, over private generators in the supply of electric power to the Mexican market and mandated a revision of power generation and transaction agreements between CFE and independent electric power suppliers. The intended reforms were challenged in court and, in January 2024, the Supreme Court ruled against the constitutionality of certain provisions of the LIE reform.

In response, the Mexican President announced a new proposal for an ambitious constitutional reform covering a wide range of topics, including energy matters. For example, changes have been introduced to the constitutional status of CFE and Pemex, resulting in increased government intervention in their policies at the expense of their boards’ independence.

The energy reform has introduced significant regulatory and legal uncertainties for energy companies, affecting their operations, financial performance, and strategic planning. Companies have had to navigate a complex and evolving regulatory landscape, invest in compliance programs, and reassess their investment strategies to mitigate the risks associated with these reforms. Uncertainty remains as to whether the Mexican government or any of its decentralized bodies will introduce new reforms to the energy market or adopt any measure that may further affect the energy supply or increase its cost. Any such new changes or measures could negatively affect our operations or those of Techgen, where Ternium holds a 48% equity interest and which supplies electricity for most of our Mexican operations. At this stage, we cannot assess the potential effects of any new governmental initiative on Ternium’s operations and the Mexican economy in general and, consequently, on the results of operations and financial conditions of our businesses in Mexico.

Violence and crime in Mexico could negatively impact Ternium’s business and operations.

Mexico is subject to significant levels of violent crimes and, notably, the regions where Ternium’s mining operations are located are subject to an increasing level of criminality, which resulted in an alarming deterioration of security conditions in the region. For more information on the events affecting our mining operations in Mexico, see “– Risks Relating to Ternium’s Mining Activities – Difficulties in relationships with local communities may adversely affect Ternium’s mining activities and results of operations, and increasing violence and crime in Mexico could result in temporary or even permanent shut down of Ternium’s Mexican mining operations.” Security issues could affect our day-to-day operations and could also result in an economic slowdown, reducing domestic demand for its products and thereby having an adverse effect on our business. A deterioration of the security situation or a surge in violence could result in significant obstacles or additional costs to the implementation of growth plans in Mexico, including delays in the completion of capital expenditures.

Changes in existing trade arrangements between Mexico and the U.S. and controversies or disputes between USMCA member countries could adversely impact Ternium’s results of operations and net results.

The USMCA became effective in July 2020 replacing the North American Free Trade Agreement (NAFTA). Previously, in 2019, Mexico and the United States had agreed to waive a 25% tariff on steel products exported to the United States (which had been imposed in 2018) subject to continuous monitoring for surges in steel imports and transshipment into the United States of material that was not imported from Mexico or Canada. Early in 2024, the United States expressed concerns regarding unfair practices in the U.S. market from steel produced in third countries that was allegedly being circumvented through Mexico. In response to such concerns, Mexico implemented additional measures aimed at improving information and transparency as well as preventing circumvention practices in connection with steel imports into the Mexican market from countries with which Mexico lacks a formal trade agreement. In addition, in July 2024, Mexican and Canadian exports to the United States of steel products melted and poured outside the USMCA region became subject to a 25% tariff under Section 232 of the Trade Expansion Act of 1962. Finally, early in 2025, the U.S. government imposed a 25% tariff on virtually all imports of steel and on certain steel derivatives, revoking previously negotiated country-specific exemptions and quota arrangements.

In addition, on February 1, 2025, the U.S. government announced the imposition, through the International Emergency Economic Powers Act ("IEEPA"), of tariffs applicable to all products imported from Mexico, Canada and China. As of the date of this annual report, Mexican and Canadian products that comply with USMCA preferential rules of origin, are exempt from this tariff. Further, the Trump administration announced that the U.S. would implement reciprocal tariffs with trading partners by April 2025.

On March 26, 2025, the U.S. government announced a 25% tariff under Section 232 on all imported automobiles produced outside the U.S., effective from April 3, 2025. This tariff will also apply to key auto parts such as engines, transmissions, powertrain parts and electrical components starting on May 3, 2025. However, vehicles and parts that comply with the USMCA will only be subject to this tariff on their non-U.S. specific content, and, in the case of auto parts, only when the government establishes a process to exempt U.S. content from tariffs.
21



This new set of tariffs and other potential commercial measures could affect market prices and dynamics, supply chains, and cost structures, and result in a prolonged or escalated trade war.

Moreover, the USMCA is scheduled for its first joint review on July 1, 2026, allowing the three member countries to assess the agreement and propose revisions. The review signals the beginning of a 10-year countdown to the USMCA’s expiration in 2036, unless the parties agree to extend the agreement. Amendments to, or the termination of, current trade agreements between Mexico and the U.S. could materially and adversely affect Ternium’s shipments, results of operations and net worth.

The introduction of new tariffs could further increase costs for Mexican exporters and, consequently, reduce Mexico’s competitiveness in the U.S. market. Particularly, new tariffs on imports of Mexican manufactured products to the U.S. market could negatively affect several of Ternium’s customers in Mexico and, thus, Ternium’s operations in the country. In addition, the uncertainty surrounding trade rules could deter foreign investment in Mexico, as companies might hesitate to invest in new projects or expand existing ones without the stability provided by the USMCA.

Other countries have announced retaliatory tariffs against U.S. exports. It is also anticipated that parties may bring litigation regarding the timeliness and appropriateness of the Trump administration’s actions. In light of the foregoing uncertainties, Ternium is unable at this time to predict the evolution or ultimate outcome of these developments or to quantify the impact that the new tariffs and measures would have on its business or financial condition.

Argentina

A significant portion of Ternium’s sales are made in Argentina mainly through its subsidiary, Ternium Argentina. Ternium Argentina’s business could be materially affected by economic, political, social, fiscal and regulatory developments in Argentina. For more information on Ternium’s sales in Argentina, see Item 4. “Information on the Company—B. Business Overview —Sales—Southern Region.”

Economic and political instability in Argentina, which on several occasions resulted in economic uncertainties and recession, may adversely affect Ternium’s business, financial condition and results.

Ternium’s business and results of operations in Argentina depend on local macroeconomic conditions, among other factors. Over the past years, the Argentine economy and capital investment have been affected by political, economic and financial uncertainties as well as government intervention in, or limitations to, the conduct of business in the private sector and other government measures affecting investors’ confidence. Steel shipments to the Argentine domestic market were severely affected in different opportunities over the last decades. For instance, during 2018 and 2019 the economy was affected by a severe downturn resulting from financial market volatility, high interest rates and heightened political uncertainty during the presidential election process and, in 2020, the economy was affected by the COVID-19 outbreak.

In 2023, the Argentine economy suffered as a result of a severe drought, foreign exchange restrictions, high inflation rates and heightened political and economic uncertainty during the presidential election process. In December 2023, the new administration, led by Mr. Javier Milei, announced a series of emergency measures to address the critical economic situation, including high inflation rates and public deficit. Some of those measures included deregulation efforts, cuts in public spending, including subsidies on public services, cut down on monetary issuance, increase of certain taxes, labor reforms, and the lifting of certain import restrictions and foreign exchange controls. In 2024, Ternium experienced a 20% decrease in steel shipments in the Southern Region primarily in connection with the Argentine government's economic stabilization measures, which had a significant impact in the first quarter followed by a gradual improvement throughout the year. It is uncertain as to what extent the Argentine government will be able to continue implementing its economic program and adopt major structural reforms. While Congress approved some of the reforms submitted by the Milei administration in 2024, it is unclear whether Congress will endorse other major reforms, including labor and tax reforms. While the deregulation of the economy and intended reforms aim to create a more competitive and investment-friendly environment, the associated uncertainties and potential for abrupt policy changes pose substantial risks for companies operating in the country. While the deregulation of the economy and intended reforms aim to create a more competitive and investment-friendly environment, the associated uncertainties and potential for abrupt policy changes pose substantial risks for companies operating in the country. In addition, conflicts between the federal and local governments may arise, court decisions may challenge governmental measures, and social tensions or public protests could arise.

Furthermore, Argentina is negotiating a new agreement with the International Monetary Fund, or IMF. Although Argentina has achieved most of the targets set under the Extended Fund Facility, or EFF arrangement for 2024, failure to implement or comply with a program with the IMF could adversely affect the country’s economy and lessened financial sources could impair Argentina’s ability to foster economic growth.
22



This context of volatility and uncertainty remains in place as of the date of this annual report. Ternium continues to monitor closely the evolution of the main variables affecting its business, identifying the potential impact thereof on its financial and economic situation and determining the appropriate course of action in each case. Ternium’s business and results of operations in Argentina could be adversely affected by rapidly changing economic, political and social conditions in Argentina, or by the Argentine government’s policy response to such conditions.

Inflation may undermine economic growth in Argentina and impact Ternium’s costs, thereby adversely affecting its results of operations and financial position.

In the past, inflation has undermined the Argentine economy and the government’s ability to stimulate economic growth. Consumer price inflation in Argentina, as reported by INDEC, the Argentine statistics and census bureau, was 118% in 2024, 211% in 2023 and 95% in 2022. In 2024, the Argentine peso depreciated by 22%, a rate that was far below the rate of inflation. Such mismatch negatively impacted our results of operations, as ARS-denominated costs (mainly labor-related costs) at Ternium Argentina increased, thereby affecting cost-competitiveness and margins. A high inflation economy has undermined and could continue to undermine Argentina’s foreign competitiveness in international markets and negatively affect economic activity and employment levels. Argentine inflation rate volatility makes it impossible to estimate with reasonable certainty the extent to which activity levels and results of operations of Ternium Argentina could be affected in the future.

Taxes on Argentine companies have been increasing over time; a further increase of the tax burden could adversely affect Ternium’s results of operations, net results and financial condition.

In the past, the sustained and significant devaluation of the Argentine peso against the U.S. dollar coupled with high inflation rates resulted in a material reduction of the real value that Ternium Argentina could deduct as cost of sales or cost of financial investments for tax purposes, thus creating artificial gains that were subject to income tax. Inflation adjustment for tax purposes is limited and subject to significant restrictions. For example, inflation adjustment of inventories and other current assets is permitted only if the consumer price inflation rate surpasses 100% in a 36-month period up to the close of the relevant fiscal year and, in the past, inflation adjustment has been further limited. If inflation rates remain high and limitations to inflation adjustment are reinstated, Ternium Argentina could be subject to increased tax burden. Furthermore, because inflation adjustment of cash positions generated during the current fiscal year is not permitted, high nominal interest rates, which are normally expected in high inflation scenarios, materially overstate the financial income of such cash positions for tax purposes.

In addition, during 2024 Ternium Argentina systematically accumulated value added and income tax credits, which amounted to $154 million as of December 31, 2024, mainly due to the impact of a 2023 federal tax agency resolution limiting several taxpayers’ ability from requesting tax credit refunds. Such resolution was recently repealed, and, therefore, Ternium Argentina expects to gradually reduce its accumulated tax credits. However, we cannot ensure that the federal tax agency will not adopt similar resolutions or measures in the future having the effect of collecting taxes in excess of applicable tax rates, thus increasing Ternium Argentina’s tax burden.

Other federal, provincial and municipal taxes on Ternium Argentina’s operations have been imposed or increased over the last years, including the introduction of a tax on dividend distributions and a tax on the purchase of foreign currency for the payment of imports of certain raw materials and intermediate goods, which was lifted in December 2024, but could be reintroduced in the future.

The Argentine government has announced plans to introduce a tax reform in 2025. Ternium cannot predict whether future legislation, or any new tax regime or reform could result in a further increase of the tax burden on its operations in Argentina, which would adversely affect Ternium’s results of operations, net results and financial condition.

Exchange controls in Argentina could negatively impact Ternium Argentina’s operations, preventing Ternium from importing raw materials, paying dividends or transferring cash surpluses abroad, as a result of its inability to access the foreign exchange market.

From time to time, the Argentine authorities have taken measures to reduce the volatility of the ARS/$ exchange rate and have implemented formal and informal restrictions on capital inflows and outflows. Between September 2019 and December 2023, the Argentine government imposed significant restrictions on foreign exchange transactions. Although after the new administration took office in December 2023 certain restrictions were eased or lifted and further deregulation is expected, at the date of this annual report the scope and timing of upcoming changes remain unknown.
23


For more information on our foreign exchange restrictions in Argentina, see note 30 “Foreign exchange restrictions in Argentina” to our consolidated financial statements included in this annual report.

Foreign exchange controls currently limit the purchase and transfer abroad of foreign currency for saving purposes, restricting Ternium Argentina’s ability to hold excess cash reserves in foreign bank accounts. Accordingly, Ternium Argentina holds its cash and financial investments in the Argentine financial system. As of December 31, 2024, Ternium Argentina’s cash and cash equivalents and other investments amounted to approximately $1.3 billion, a large portion of which consisted of U.S. dollar-denominated sovereign bonds issued by the Argentine government and payable in U.S. dollars, and Argentine Treasury bonds linked to the official exchange rate. The U.S. dollar value of these instruments recorded in Ternium’s consolidated financial statements is based on their Argentine peso local market price, converted to the U.S. dollar at the ARS/$ official exchange rate. Therefore, the valuation of such investments is subject to the volatility of the Argentine financial market and currency exchange rates, leading to a potential significant reduction of such value in our consolidated financial statements. For example, during the fourth quarter of 2023 and first quarter of 2024, Ternium’s divestment of Argentine sovereign bonds resulted in a loss of $164 million due to the recycling of changes in the fair value of financial instruments from Other Comprehensive Income to Financial Results. Although the balance of Ternium’s Other Comprehensive Income in connection with its Argentine sovereign bond holdings turned positive as of December 31, 2024, this balance could turn negative again in the future if conditions in the Argentine financial market deteriorate and, consequently, the market value of such holdings decreases.

In the past few years, the Argentine authorities limited the import of goods and services by Argentine companies, including Ternium Argentina and other companies in the steel value chain, by controlling access to the foreign exchange market. In the context of high, but decelerating, inflation during 2024, restrictions of access to the foreign exchange market to pay for imports of goods remain, but have been gradually made more flexible. However, Ternium cannot predict future conditions for the imports of goods and services by Argentine companies, which would adversely affect Ternium’s results and financial condition.

Access to the official exchange market to make dividend payments continue to require prior Argentine Central Bank approval, which is rarely, if ever, granted.

If control systems are maintained or are tightened, local demand for steel products and/or Ternium Argentina’s operations or sales could be adversely affected, Ternium Argentina could be exposed to the risk of losses arising from fluctuations in the ARS/$ exchange rate, and Ternium Argentina’s ability to make payments to foreign suppliers or creditors (which could disrupt Ternium Argentina’s operations), pay dividends or royalties abroad, or fund investments or other activities offshore could be impaired.

Brazil

Ternium has significant manufacturing operations and assets located in Brazil. Ternium has a participation in the control group of Usiminas, a large Brazilian steelmaker, and began consolidating Usiminas in July 2023. Ternium also owns Ternium Brasil, a company that has a slab making facility in Rio de Janeiro and exports most of its production. Ternium’s results and net worth could be materially and adversely affected by economic, political, social, fiscal and regulatory developments, as well as security concerns in Brazil.

Changing economic policies and political conditions in Brazil, which on several occasions in the past resulted in economic uncertainties, recession and political instability, may occur in the future, thereby adversely affecting Ternium’s business results and financial condition.

The Brazilian economy has been characterized by frequent and occasionally extensive intervention by the Brazilian government, including changed monetary, taxation, credit, tariff and other policies to influence the course of the country’s economy. The Brazilian government’s actions to control inflation and implement other policies have involved hikes in interest rates, wage and price controls, foreign exchange controls and devaluation, freezing of bank accounts, capital controls and restrictions on imports. Such policies may adversely affect our results and net worth. The Brazilian government’s policies may also result in increases in tax payments or tariffs, which could adversely affect industry profitability. Changes in tax laws, such as the ongoing tax reform debates, can result in increased tax liabilities and compliance costs, creating uncertainties for businesses. In addition, tax disputes can result in substantial financial liabilities and require extensive legal resources to resolve. We cannot predict whether the new tax regime would result in a net tax burden increase for our operations in Brazil. Any increase in the applicable tax burden or tariffs would affect our consolidated cash flow and profitability. Also, tax disputes are a common source of legal uncertainty for Brazilian companies. The interpretation of tax laws by authorities can vary, leading to disputes over tax liabilities. In the past, Ternium’s Brazilian subsidiaries faced several tax-related legal challenges, including disputes over the collection of federal, state and municipal taxes, transfer pricing, and the deductibility of certain expenses.
24



The Brazilian economy has been affected by inflation, energy shortages, illiquid lending markets and other political, diplomatic, social and economic developments. Brazil’s political environment has historically influenced, and continues to influence, the performance of the country’s economy. Political crises have affected public and investor confidence, which resulted in economic deceleration. For example, Brazil has experienced heightened economic and political instability derived from various investigations into allegations of money laundering and corruption being conducted by the Office of the Brazilian Federal Prosecutor, including the Lava Jato investigation, which negatively impacted the Brazilian economy and political environment and contributed to a decline in market confidence in Brazil. In addition, operational risks in Brazil include challenges related to infrastructure, supply chain disruptions, and labor disputes. Companies also face risks related to strikes and labor disputes, which can disrupt operations and lead to financial losses.

The Brazilian judicial system is known for its procedural delays and the unpredictability of outcomes. Companies often face lengthy judicial, arbitral, and administrative proceedings, which can be further complicated by the possibility of appeals and the need for judicial guarantees; and the enforcement of judicial decisions may be challenging.

Uncertainty over whether the Brazilian government will change policies or regulations affecting economic, political or social factors may contribute to economic instability in Brazil. We cannot predict whether political instability will arise in the future nor its effect on the Brazilian economy and, consequently, on the results of operations and financial conditions of our businesses in Brazil.

Inflation may undermine economic growth in Brazil and impact Ternium’s costs, thereby adversely affecting its results of operations and financial position.

High levels of inflation have in the past undermined the Brazilian economy and the government’s ability to stimulate economic growth. Our results of operations and financial position could be negatively impacted, as BRL-denominated costs (mainly labor-related costs) may increase, thereby affecting cost-competitiveness. Inflationary pressures may also lead to the imposition of additional government policies to combat inflation and hinder access to Brazilian capital markets, which could adversely affect the business and the ability to finance operations and capital expenditures, making it impossible to estimate with reasonable certainty our future results of operations.

Certain Regulatory Risks And Litigation Risks

Ternium faces a significant loss contingency in Brazil in connection with its acquisition of a participation in the control group of Usiminas.

In 2013, Ternium was notified of a lawsuit filed in Brazil by Companhia Siderúrgica Nacional (“CSN”) and various entities affiliated with CSN against Ternium Investments, Ternium Argentina, and Tenaris’s subsidiary, Confab, all of which compose the T/T Group under the Usiminas shareholders agreement. The entities named in the CSN lawsuit had acquired a participation in Usiminas in January 2012. The CSN lawsuit alleges that, under applicable Brazilian laws and rules, the acquirers were required to launch a tag-along tender offer to all non-controlling holders of Usiminas ordinary shares for a price per share equal to 80% of the price per share paid in such acquisition or BRL28.8 and seeks an order to compel the acquirers to launch an offer at that price plus interest. If so ordered, the offer would need to be made to 182,609,851 ordinary shares of Usiminas not belonging to Usiminas’ control group. Ternium Investments and Ternium Argentina’s respective shares in the offer would be 60.6% and 21.5%.

On September 23, 2013, the first instance court dismissed the CSN lawsuit, and on February 8, 2017, the court of appeals maintained the understanding of the first instance court. On August 18, 2017, CSN filed an appeal to the Superior Court of Justice (SCJ) seeking the review and reversal of the decision issued by the Court of Appeals. On September 10, 2019, the SCJ declared CSN’s appeal admissible. On March 7, 2023, the SCJ, by majority vote, rejected CSN’s appeal. CSN made several submissions in connection with the SCJ decision, including a motion for clarification that challenged the merits of the SCJ decision. Decisions at the SCJ are adopted by majority vote. At an October 17, 2023 session, two justices of the SCJ voted in favor of remanding the case to the first instance for it to be retried following production and assessment of the new evidence, and two justices of the SCJ voted, without requiring any further evidence, in favor of granting CSN’s motion for clarification and reversing the March 7, 2023 decision that rejected CSN’s appeal; because the fifth member of SCJ excused himself from voting, a justice from another panel at the SCJ was summoned to produce the tie-breaking vote.

On June 18, 2024, the SCJ completed its voting on CSN’s motion for clarification and reversed, by majority vote, its March 7, 2023 decision, and resolved that Ternium Investments, its subsidiary Ternium Argentina and Tenaris’s subsidiary Confab should pay CSN an indemnification in connection with the acquisition by the T/T Group a participation in Usiminas in January 2012, with CSN being allowed to retain ownership of the Usiminas ordinary shares it currently owns.
25


On August 1, 2024, Ternium Investments, Ternium Argentina and the other T/T Group entities filed a motion for clarification against the SCJ decision and, subsequently, CSN filed its reply. On December 6, 2024, the SCJ rejected this motion for clarification, confirming the obligation of the T/T Group entities to pay indemnification in connection with the 2012 acquisition of the participations in Usiminas. Notwithstanding the foregoing, the SCJ unanimously resolved to modify the applicable monetary adjustment mechanism and to cap the applicable attorney’s fees, thereby lowering the aggregate amount that would be payable if CSN ultimately prevails in this claim. Based on such SCJ decision, assuming monetary adjustment through December 31, 2024, and attorney’s fees in the amount of BRL5 million, the revised aggregate amount potentially payable by Ternium Investments and Ternium Argentina if CSN finally prevails on its claims would be of approximately BRL1,875.9 million (approximately $302.9 million at the BRL/$ rate as of such date) and BRL664.1 million (approximately $107.3 million at the BRL/$ rate as of such date), respectively. On February 10, 2025, Ternium filed an extraordinary appeal against the SCJ decisions that ordered an indemnification payment, seeking their review and reversal by the Supreme Federal Tribunal. The Company, however, cannot predict the ultimate resolution on the matter. For further information see note 25 “Contingencies, Commitments and Restrictions on the Distribution of Profits—Tax claims and other contingencies (a) Provision for ongoing litigation related to the acquisition of a participation in Usiminas”, to our consolidated financial statements included in this annual report.

International trade actions or regulations and trade-related legal proceedings could adversely affect Ternium’s sales and revenues and the overall business.

International trade-related administrative proceedings, legal actions and restrictions pose a constant risk for international operations and sales throughout the world. Our steel processing activities require steel products, including significant quantities of steel slabs, from different foreign steel suppliers for its operations in Mexico, Colombia, Argentina and Brazil. The Mexican, Colombian, Argentine or Brazilian governments may impose or increase duties on steel products imports. On the other hand, trade liberalization, mainly through free trade agreements, can reduce certain input costs and increase access to foreign markets. However, greater trade liberalization in the domestic markets in which we participate increases competition. For example, during 2024, the Argentine government took several measures to streamline the import of goods, which could increase the risk of unfairly traded imports affecting the local market. For information concerning competition in the domestic steel markets, see “Intense competition could cause Ternium to lose its market share and adversely affect its revenues.”

During the last decade, steel exports from China surged as a consequence of an economic slowdown in this country, and the number of antidumping, countervailing, safeguard measures and other trade restrictive actions increased substantially. Accordingly, producers that were restricted from certain markets sought alternative markets for their products. In the last two years, there was a surge of steel exports from China resulting in an increase to export volumes of approximately 38% year-over-year in 2023, and an additional 25% year-over-year in 2024. Consequently, flat steel imports in Brazil surged approximately 42% in 2023 and a further 11% in 2024, mainly due to the import of low-priced Chinese steel products. Continued increase in steel imports under unfair trade conditions could erode our sales in domestic markets, and such market share losses may not be completely offset by increased exports to foreign markets.

Countries or regional blocs may impose restrictive import duties and other restrictions on imports under various trade related laws, such as national security, environmental and intellectual property regulations. For example, Ternium is affected by tariffs on steel imports imposed by the United States under Section 232 of the Trade Expansion Act of 1962. For more information on tariffs see, “Risks Relating to the Countries in Which Ternium Operates – Mexico - Changes in existing trade arrangements between Mexico and the U.S., and controversies or disputes between USMCA member countries could adversely impact Ternium’s results of operations and net results.”

The timing and nature of the imposition of trade-related restrictions potentially affecting Ternium’s sales and that of Ternium’s customers are unpredictable. Tariffs and trade restrictions on exports could adversely impact our or our customers’ ability to sell products and, as a result, the overall business and our profit margins and financial condition could suffer. One significant source of trade restrictions is the imposition of “antidumping” and “countervailing” duties, as well as “safeguard measures”. These duties can severely limit or altogether prevent exports to relevant markets. In several export destination that are relevant to Ternium, such as the United States, safeguard duties and other protective measures have been imposed against a large number of steel imports. For further information, see Item 4. “Information on the Company-B. Business Overview Regulations-Trade Regulations”, and “Risks Relating to the Countries in Which Ternium Operates – Mexico - Changes in existing trade arrangements between Mexico and the U.S., and controversies or disputes between USMCA member countries could adversely impact Ternium’s results of operations and net results.”

Certain domestic producers have filed antidumping and/or countervailing duty actions against certain steel imports. Some of these actions have led, or may lead, to restrictions on our sales of steel products in certain steel markets and result in lower profit margins. For example, on September 26, 2024, the U.S. Department of Commerce announced the initiation of antidumping duty investigations from corrosion-resistant steel products from Australia, Brazil, Canada, Mexico, the Netherlands, South Africa, Taiwan, the Republic of Turkey, the United Arab Emirates, and the Socialist Republic of Vietnam, and countervailing duty investigations of such products from Brazil, Canada, Mexico, and Vietnam. Antidumping and/or countervailing duty actions and other government actions are largely unpredictable and additional duties or restrictions could be imposed in the future, limiting our sales to and potential growth in those markets, and increasing costs.

The cost of complying with environmental regulations, potential product and environmental liabilities in a context of increasing environmental awareness, as well as governmental measures driven by social pressure to address environmental concerns, may affect Ternium’s steel production or processing operations, or may increase Ternium’s operating costs, negatively impacting Ternium’s business, financial condition, results of operations and prospects.

Steelmaking and mining activities are subject to a wide range of local, provincial and national laws, regulations, permit requirements and decrees relating to the protection of human health and the environment, including laws and regulations relating to hazardous materials and radioactive materials and environmental protection governing air emissions, water discharges and waste management due to the risks inherent in the steel and mining industries. Laws and regulations protecting the environment have become increasingly complex and more stringent in recent years, leading to higher compliance costs.

We are required to obtain certain permits, licenses and authorizations from local, provincial or federal authorities for purposes of carrying out certain operations. Failure to obtain or renew such permits, licenses or authorizations, or to comply with their terms, may result in delays, fines, closure orders or requirements to halt or curtail our operations, negatively affecting our results.

Furthermore, environmental laws and regulations may, in some cases, impose strict liability for damages to natural resources or threats to public health and safety without regard to negligence or fault. Some environmental laws provide for joint and several strict liability for remediation of spills and releases of hazardous substances. Such laws and regulations may expose Ternium to liability for the conduct of, or conditions caused by, third parties or for actions that complied with applicable laws at the time they were performed adversely affecting our business, financial condition, results of operations and prospects.

Our steel operations may also be subject to claims under federal and local laws and regulations on liability arising from damages to natural resources, release of toxic substances or other environmental damages, as well as for the investigation and clean-up of soil, surface water, sediments, groundwater and other natural resources. Claims for damages may arise with respect to current or former conditions at active or inactive sites that Ternium currently owns, leases or operates or at leased-land sites and third-party waste disposal sites. We may also be subject to litigation for alleged bodily injuries arising from claimed exposure to hazardous substances allegedly used, released, or disposed of by Ternium. Environmental damages caused by steel and mining operations may result in costs and liabilities that could materially and adversely affect Ternium’s margins, cash flow and profitability. Third-party claims based on environmental or physical damages may exceed the limit of liability of the insurance policies that Ternium may have in place.

In addition, increasing public awareness on environmental matters put pressure on governmental authorities to adopt measures or take initiatives that show concern for such matters, including by inspecting, monitoring or sanctioning local industries. We face risks from litigation and government enforcement proceedings alleging non-compliance with applicable laws or regulations. These actions can be driven by public policy agendas addressing environmental concerns. The use of state power and the legal system to promote such agendas can result in significant financial liabilities and operational disruptions. Even if we comply with environmental regulations, we cannot assure that governmental authorities will not request Ternium to suspend or close its operations, which would disrupt production, adversely affecting Ternium’s business and results of operations.

For example, the city and metropolitan area of Monterrey in Nuevo León, Mexico, evidence unsatisfactory air quality indexes most days of the year, mainly because of human factors and an arid surrounding soil enclosed by hills. From time to time, particularly when the quality of the air is below acceptable rates, public opinion focuses on this matter and Ternium’s local operations become subject to further scrutiny. In January 2024, in response to media’s intense coverage of air quality issues in Monterrey and public opinion focus on the matter, the local authority inspected our Guerrero steelmaking facility. Although authorities concluded that the plant was in compliance with air emissions standards, air pollution remains a subject of local concern.
27


More recently, the Mexican Federal Environmental Protection Office (Profepa) National Water Commission (Conagua) ordered a temporary closure of the wastewater discharge of Ternium Mexico’s plant in Puebla alleging incompliance with water discharge permits and made certain unfounded allegations against Ternium Mexico. While Ternium Mexico complies with all applicable environmental and regulatory requirements and this measure has not had a material adverse impact on Ternium Mexico’s operations, this situation evidences the risk of disruption to our operations arising from increased governmental intervention and the adoption of groundless sanctioning measures influenced by social and political pressures.

While we incur and will continue to incur expenditures to comply with applicable laws and regulations, there always remains a risk that environmental incidents or accidents may occur that may negatively affect our operations or reputation, trigger investigations or litigation resulting in an obligation to pay damages or incur remediation costs, or that governmental authorities or a court order request Ternium to suspend or close its operations.

Some of the activities for which Ternium supplies products, such as production of food cans, construction and the automotive industry, are subject to inherent risks that could result in death, personal injury, property damage or environmental pollution, and result in product liability risks that could extend to liability for damages caused by such products. Furthermore, products are also sold to, and used in, certain safety-critical appliances. Actual or claimed defects in such products may give rise to claims for losses suffered by customers and expose Ternium to financial losses from claims for damages. The insurance we maintain will not be available in cases of gross negligence or willful misconduct; in other cases, insurance may not be adequate or available to protect us in the event of a claim, its coverage may be limited, canceled or otherwise terminated, or the amount of insurance may be less than the related impact on the enterprise value after a loss.

Climate change legislation and increasing climate regulatory requirements aimed at transitioning to a lower-carbon economy, together with increasing stakeholder expectations for reduced carbon emissions, could result in unexpected capital expenditures and costs, negatively affect Ternium’s competitiveness, reducing its market share and results of operations, and hampering its ability to access adequate financial resources.

There has been a growing awareness on greenhouse gas (GHG) emissions and climate change across different sectors of society over the last few years. The Paris Agreement, adopted at the 2015 United Nations Climate Conference, sets out the global framework to limit the planet’s rising temperature and to strengthen the countries’ ability to deal with the effects of climate change. The EU Emissions Trading System (ETS) signaled a major EU energy policy to combat global warming based on a “cap & trade” program, and the European Green Deal, launched in 2019, focuses on adopting the required policies and measures aimed at achieving zero GHG emissions in Europe by 2050. The EU Taxonomy Regulation establishes a classification system for environmentally sustainable economic activities, laying out definitions to businesses, stakeholders and policymakers on which economic undertakings can be considered environmentally sustainable and requiring companies to disclose, in the annual reports, how environmentally sustainable their economic activities are. In addition, as part of the European Green Deal, the EU adopted the Corporate Sustainability Reporting Directive (CSRD), which requires European large companies and listed issuers to disclose information on their risks and opportunities arising from social and environmental issues, and on the impacts of their activities on people and the environment, and the Corporate Sustainability Due Diligence Directive (CSDDD), which mandates that companies operating within the European Union identify, prevent, mitigate, and account for adverse human rights and environmental impacts in their operations and supply chains. Similarly, EU’s Carbon Border Adjustment Mechanism (CBAM), which was adopted on May 17, 2023, aims at promoting the reduction of emissions worldwide by subjecting the import of certain products, including steel, from countries outside of the European Union to a carbon levy linked to the carbon price payable for goods produced in EU countries. However, in response to the need to strengthen the EU’s competitiveness and make the EU economy more prosperous, the European Commission has recently proposed to simplify sustainability reporting rules. The package proposes amendments to the Corporate Sustainability Reporting Directive (CSRD), the EU Taxonomy, the Corporate Sustainability Due Diligence Directive (CSDDD), the EU’s Carbon Border Adjustment Mechanism (CBAM) and current investment programs. If the package is approved, Ternium will be required to comply with the Corporate Sustainability Reporting Directive (CSRD) and the EU Taxonomy, with respect to Ternium S.A.’s 2027 annual report, and with the Corporate Sustainability Due Diligence Directive (CSDDD) starting on July 2028, but its sustainability reporting and due diligence burdens will be reduced and simplified.

Similarly, in response to an increasing investor focus and reliance on climate and ESG-related disclosure and investment, the Securities and Exchange Commission (SEC) announced in March 2021 the creation of a Climate and ESG Task Force to identify ESG-related misconduct and potential violations, and in March 2022, the SEC released a proposal to amend its disclosure rules. In March 2024, the SEC adopted the final rule on climate-related disclosures, which would have required registrants, including Ternium S.A., to significantly expand the climate-related disclosures in their periodic reports, including information about climate-related risks that are reasonably likely to have a material impact on their business, results of operations, or financial condition, and certain climate-related financial statement metrics in a note to their audited financial statements. The implementation of this rule had been voluntarily stayed by the SEC in April 2024, pending judicial review due to legal challenges and, on March 27, 2025, the SEC with drew its legal defense of the climate change rule.
28


Other countries are introducing or considering similar measures or regulations with the aim at lowering emissions as well as government initiatives to promote the use of alternative energy sources and substitute existing products and services with lower emissions alternatives (with many jurisdictions implementing tax advantages and other subsidies to promote the development of renewable energy sources, or even requiring minimum thresholds for power generation from renewable sources).

Ternium’s industrial system includes two main technological routes to produce steel: the blast furnace / basic oxygen furnace route (BF/BOF) and the direct reduction / electric arc furnace route (DRI/EAF). The BF/BOF route has a significantly higher carbon emission intensity than the DRI/EAF route. Although several new initiatives and pilot projects under development seek to significantly reduce the BF/BOF route carbon emission intensity, no technology has yet achieved sufficient technology readiness level, nor is any technology available at scale or economically feasible, and there is no certainty that any such technology will be available in the near future. Ternium is developing several projects aimed at reducing carbon emission intensity. These projects could experience delays or higher-than-anticipated costs, or may not yield the expected results. In addition, the adoption of any new technology could require significant investments and could potentially lead to a reduction in the useful life of current equipment and the recognition of impairment charges. These issues affect most steel companies, as the BF/BOF route currently represents approximately 72% of global steelmaking production capacity. For further information about Ternium’s technological routes to produce steel, see item 4. “Information on the Company – B. Business Overview – Production Facilities and Processes”.

Government and international organization’s initiatives to promote the reduction of GHG emissions, such as the introduction of a carbon tax or carbon-pricing systems, the adoption of “cap-and-trade” systems or measures to avoid carbon leakage or promote the use of renewable energy sources could affect Ternium’s steel production costs.

In Argentina, the 2017 tax reform introduced a tax on certain fossil fuels, which did not include natural gas. Metallurgical coal and petrochemical coke were exempted as long as they are used as part of an industrial process, other than for energy generation. Effective since March 2018, the tax on fossil fuels is set to increase 10% every year until 2028, when it is expected to reach an average $10 per ton of carbon dioxide equivalent emitted. Similarly, in 2013, Mexico approved carbon taxing rules applicable to fossil fuels (setting a zero tax on natural gas) and in 2019 the government implemented a pilot program for the adoption of an Emissions Trading System aimed at reducing GHG emissions, by setting a cap on emissions and allowing for the trade of emission certificates. For the time being, there is no regulation for setting such system nor to determine allowances. Although existing carbon pricing mechanisms in Mexico and Argentina do not materially limit or penalize Ternium’s GHG emissions, new carbon pricing mechanisms could increase Ternium’s production costs. Particularly in Mexico, the state governments could set carbon taxes on top of the federal tax regime and the Emission Trading System. In addition, the Brazilian Congress has recently approved an initiative to introduce an emission trading scheme for industry processes and power generation facilities, which, if applicable to Ternium Brasil’s and Usiminas’ operations, would result in incremental costs in the future. Such increases in costs could affect, in turn, Ternium’s profitability and net results.

If there is not enough progress in significantly reducing emissions in the coming years, or emerging technologies for the reduction of carbon emission intensity of the BF/BOF route are not commercially available or are not economically viable, there is an increased likelihood of abrupt policy interventions as governments attempt to meet their environmental goals by adopting policy, legal, technology and market changes in the transition to a low-carbon global economy. In addition to incremental production costs, the adoption of new climate change legislation in the countries in which we operate could result in incremental compliance costs and unexpected capital expenditures, affect our competitiveness and reduce our market share and results of operations.

Furthermore, shifts in customer preferences and failure to respond to stakeholders’ demand for climate-related measures and environmental standards could adversely affect the ability or willingness of our customers or suppliers to do business with us, harm our reputation, erode stakeholder support and restrict or reduce access to financial resources.

Risks Relating To Ternium S.A.’s ADS

The market price for Ternium S.A.’s ADS could be highly volatile.

Volatility in the price of Ternium S.A.’s ADS may be caused by factors within or outside of its control and may be unrelated or disproportionate to Ternium’s operating results. In particular, the announcement of potentially adverse developments, such as proposed regulatory changes, new government investigations or the commencement or threat of litigation against Ternium, as well as the announcement of transactions, investments, or changes in strategies or business plans of Ternium or its competitors, could adversely affect the trading price of Ternium S.A.’s ADS, regardless of the likely outcome of those developments.
29


Broad market and industry factors could adversely affect the market price of Ternium S.A.’s ADS, regardless of their actual effect on operating performance. The trading price of Ternium S.A.’s ADSs could also suffer as a result of developments in emerging markets. Although Ternium S.A. is organized as a Luxembourg corporation, it has substantial assets with operations in Mexico, Brazil, Argentina and Colombia. Financial and securities markets for companies with a substantial portion of their assets and exposure in Latin America are, to varying degrees, influenced by political, economic and market conditions in emerging market countries. Although market conditions are different in each country, investor reaction to developments in one country can have significant effects on the securities of issuers with assets and exposure in other emerging markets, including Mexico, Brazil, Argentina and Colombia. See “Risks Relating to the Countries in Which Ternium Operates.”

Holders of shares or ADSs may not have access to as much information about Ternium S.A. as they would in the case of a U.S. domestic issuer.

There may be less publicly available information about Ternium S.A. than is regularly published by or about U.S. domestic issuers. Also, corporate and securities regulations governing Luxembourg companies may not be as extensive as those in effect in other jurisdictions, and U.S. securities regulations applicable to foreign private issuers, such as Ternium S.A., differ in certain respects from those applicable to U.S. domestic issuers. Furthermore, IFRS, the accounting standards in accordance with which Ternium S.A. prepares its consolidated financial statements, differ in certain material aspects from U.S. GAAP. For a summary of the significant ways in which Ternium S.A.’s corporate governance practices differ from the corporate governance standards required for domestic companies by The New York Stock Exchange (“NYSE”), see Item 16.G “Corporate Governance.”

Holders of ADSs may not be able to exercise, or may encounter difficulties in the exercise of, certain rights afforded to shareholders.

Certain shareholders’ rights under Luxembourg law, including the right to participate and vote at general meetings of shareholders, to include items on the agenda for the general meetings of shareholders, to receive dividends and distributions, to bring actions, to examine books and records and to exercise appraisal rights may not be available to holders of ADSs, or may be subject to restrictions and special procedures for their exercise, as holders of ADSs only have those rights that are expressly granted to them in the deposit agreement. The Bank of New York Mellon, or BNY Mellon, as depositary under the ADS deposit agreement, through its custodian agent, is the registered shareholder of the deposited shares underlying the ADSs and therefore only the Depositary can exercise the shareholders’ rights in connection with the deposited shares. For example, if Ternium S.A. makes a distribution in the form of securities, the Depositary is allowed, at its discretion, to sell the right to acquire those securities on your behalf and to instead distribute the net proceeds to you. Also, under certain circumstances, such as Ternium S.A.’s failure to provide the Depositary with voting materials on a timely basis, you may not be able to vote at general meetings of shareholders by giving instructions to the Depositary. If the Depositary does not receive voting instructions from the holder of ADSs by the prescribed deadline, or the instructions are not in proper form, then the Depositary shall deem such holder of ADSs to have instructed the Depositary to vote the underlying shares represented by ADSs in favor of any proposals or recommendations of Ternium S.A. (including any recommendation by it to vote such underlying shares on any given issue in accordance with the majority shareholder vote on that issue) for which purposes the depositary shall issue a proxy to a person appointed by Ternium S.A. to vote such underlying shares represented by ADSs in favor of any of proposals or recommendations of Ternium S.A. Under the ADS deposit agreement, no instruction shall be deemed given and no proxy shall be given with respect to any matter as to which Ternium S.A. informs the Depositary that (x) it does not wish such proxy given, (y) substantial opposition exists, or (z) the matter materially and adversely affects the rights of the holders of ADSs.

Holders of shares and ADSs in the United States may not be able to exercise preemptive rights in certain cases.

Pursuant to Luxembourg corporate law, existing shareholders of Ternium S.A. are generally entitled to preferential subscription rights (preemptive rights) in the event of capital increases and issues of shares against cash contributions. Under Ternium S.A.’s articles of association, the board of directors has been authorized for a five-year period to waive, limit or suppress such preemptive subscription rights. Although the validity period of such authorization will expire in June 2025, the board of directors has convened an extraordinary meeting of shareholders to be held on May 6, 2025, which will consider the renewal of such authorization for an additional five-year period. Notwithstanding the waiver of any preemptive subscription rights, for as long as the shares of Ternium S.A. are listed on a regulated market, any issuance of shares for cash within the limits of the authorized share capital shall be subject to the preemptive subscription rights of existing shareholders, except (i) any issuance of shares for, within, in conjunction with or related to, an initial public offering of the shares of Ternium S.A.
30


on one or more regulated markets (in one or more instances); (ii) any issuance of shares against a contribution other than in cash; (iii) any issuance of shares upon conversion of convertible bonds or other instruments convertible into shares of Ternium S.A.; provided, however, that the preemptive subscription rights of the then-existing shareholders shall apply in connection with any issuance of convertible bonds or other instruments convertible into shares of Ternium S.A. for cash; and (iv) any issuance of shares (including by way of free shares or at discount), up to an amount of 1.5% of the issued share capital of Ternium S.A., to its directors, officers, agents, employees, its direct or indirect subsidiaries or its affiliates (collectively the "Beneficiaries"), including without limitation, the direct issuance of shares or upon the exercise of options, rights convertible into shares or similar instruments convertible or exchangeable into shares, issued for the purpose of compensation or incentive of the Beneficiaries or in relation thereto (which the board of directors shall be authorized to issue upon such terms and conditions as it deems fit). For further details, see Item 10. “Additional Information—B. Memorandum and Articles of Association”.

Holders of ADSs in the United States may, in any event, not be able to exercise any preemptive rights, if granted, for shares underlying their ADSs unless additional shares and ADSs are registered under the U.S. Securities Act of 1933, as amended, or the Securities Act, with respect to those rights or an exemption from registration requirements of the Securities Act is available. Ternium S.A. intends to evaluate, at the time of any rights offering, the costs and potential liabilities associated with the exercise by holders of shares and ADSs of the preemptive rights for shares, and any other factors it considers appropriate at the time, and then to make a decision as to whether to register additional shares. Ternium S.A. may decide not to register any additional shares, requiring a sale by the Depositary of the holders’ rights and a distribution of the proceeds thereof. Should the Depositary not be permitted or otherwise be unable to sell preemptive rights, the rights may be allowed to lapse with no consideration to be received by the holders of the ADSs.

It may be difficult to obtain or enforce judgments against Ternium S.A. outside Luxembourg.

Ternium S.A. is a société anonyme organized under the laws of the Grand Duchy of Luxembourg, and most of its assets are located in other jurisdictions. Furthermore, most of its directors and officers reside in other jurisdictions. As a result, investors may not be able to effect service of process upon Ternium S.A. or its directors or officers. Investors may also not be able to enforce against Ternium S.A. or its directors or officers in the investors’ domestic courts, judgments predicated upon the civil liability provisions of the domestic laws of the investors’ home countries. Likewise, it may be difficult for investors not domiciled in Luxembourg to bring an original action in a Luxembourg court predicated upon the civil liability provisions of other securities laws, including U.S. federal securities laws, against Ternium S.A., its directors or its officers. There is also uncertainty with regard to the enforceability of original actions of civil liabilities predicated upon the civil liability provisions of securities laws, including U.S. federal securities laws, outside the jurisdiction where such judgments have been rendered; and enforceability will be subject to compliance with procedural requirements under applicable local law, including the condition that the judgment does not violate the public policy of the applicable jurisdiction.

A.    History and Development of the Company
The Company
Ternium S.A. is a société anonyme organized under the laws of the Grand-Duchy of Luxembourg established on December 22, 2003. Its registered office is located at 26 Boulevard Royal – 4th floor, L-2449 Luxembourg. Its agent for U.S. federal securities law purposes is Ternium U.S.A. Incorporated, located at 2200 West Loop South, Suite 945, Houston, TX 77027, United States.

Ternium
Ternium’s origins began in September 1961 with the founding of Propulsora Siderúrgica ("Propulsora") by San Faustin’s predecessor in Argentina. Propulsora began its operations as a producer of cold-rolled coils in December 1969 and in the early 1990s began to evolve through a series of strategic investments aimed at transforming Propulsora into an integrated steel producer. In 1993, Propulsora merged with Aceros Paraná S.A. (a company formed by the Argentine government in connection with the privatization of Sociedad Mixta Siderúrgica Argentina ("Somisa"), at that time the main integrated producer of flat steel in Argentina) and three other affiliated steel industry companies. After the merger, Propulsora changed its name to Siderar, and later to Ternium Argentina. San Faustin held a controlling interest in Siderar, with the remainder being held mainly by Usiminas, certain former employees of Somisa, and public investors.
32


In December 1997, a consortium formed by San Faustin, Ternium Argentina, Usiminas, Hylsamex S.A. de C.V. ("Hylsamex"), and Siderurgica Venezolana S.A. ("Sivensa"), won the bid in the privatization of a controlling interest in Sidor C.A. ("Sidor"), the largest steel company in Venezuela.
As part of a multiple-step corporate reorganization in 2005, San Faustin reorganized its investments in steel manufacturing, processing and distribution businesses by contributing to Ternium S.A. San Faustin’s controlling interests in Ternium Argentina and other subsidiaries, in exchange for shares of Ternium S.A. In addition, Usiminas and Sivensa exchanged their interests in Ternium Argentina, Sidor and other subsidiaries for shares of Ternium S.A. In 2005, we acquired, together with Ternium Argentina, an indirect 99.3% interest in the Mexican company Hylsamex and its subsidiaries.
On January 11, 2006, Ternium S.A. launched an initial public offering of 24,844,720 ADSs, each representing 10 shares, in the United States, and subsequently granted the underwriters of Ternium S.A.’s initial public offering an option to purchase up to 3,726,708 additional ADSs to cover over-allotments in the sale of the ADSs.
On December 28, 2006, Ternium acquired an additional 4.85% interest in Ternium Argentina from CVRD Internacional S.A., thereby increasing our ownership interest in Ternium Argentina to 60.93%.
On April 29, 2007, Ternium acquired Grupo Imsa through a cash tender offer and a cash redemption. Grupo Imsa was renamed Ternium Mexico and, effective March 31, 2008, Hylsamex merged with and into Ternium Mexico. In connection with this merger, Ternium Argentina acquired, and currently holds, a 28.73% participation in Ternium Mexico.
In April 2008, the National Assembly of Venezuela declared Sidor of public and social interest, and authorized the Venezuelan government to expropriate the company and its assets. On May 7, 2009, Ternium completed the transfer of its entire 59.7% interest in Sidor to Corporación Venezolana de Guayana, a Venezuelan state-owned entity.
On August 25, 2010, Ternium completed the acquisition of a 54% ownership interest in Ferrasa and, indirectly, in its wholly-owned Colombian subsidiaries, Siderúrgica de Caldas S.A.S. and Perfilamos del Cauca S.A.S. On April 7, 2015, Ternium acquired the remaining 46% minority interest in Ferrasa. Through this investment, Ternium expanded its business and commercial presence in Colombia. In 2017, Ferrasa was renamed Ternium Colombia.
In November 2010, Ternium and NSC established Tenigal, with each company holding 51% and 49% participations, respectively. Tenigal completed the construction of a hot dip galvanizing plant in the vicinity of Monterrey City, Mexico, which commenced production in the third quarter of 2013. Tenigal was designed to produce high grade and high quality galvanized and galvannealed automotive steel sheets, including outer panel and high strength qualities.
On January 16, 2012, Ternium S.A.’s subsidiaries, Ternium Investments and Ternium Argentina (together with its wholly-owned subsidiary Prosid Investments S.A., or "Prosid", and Ternium S.A.’s affiliate, Confab Industrial S.A., a subsidiary of Tenaris, or TenarisConfab), joined the existing control group of Usiminas, a leading steel company in the Brazilian flat steel market, through the acquisition of 84.7, 30.0, and 25.0 million ordinary shares, respectively, and formed the so-called Ternium/Tenaris (T/T) Group.
On October 30, 2014, Ternium Investments acquired 51.4 million additional ordinary shares of Usiminas. On April 20, 2016, Ternium Investments subscribed to 7.0 million preferred shares of Usiminas and Ternium Argentina, together with Prosid, subscribed to an aggregate 1.5 million preferred shares of Usiminas. On July 19, 2016, Usiminas’ extraordinary general shareholders’ meeting homologated a capital increase, and Ternium Investments acquired 62.6 million additional ordinary shares, and Ternium Argentina and Prosid acquired an aggregate 13.8 million additional ordinary shares.
On September 7, 2017, Ternium S.A. acquired a 100% ownership interest in thyssenkrupp Slab International B.V or tkSI, and its wholly-owned subsidiary CSA from thyssenkrupp AG, or tkAG. Through this investment, Ternium significantly expanded its steel slabs production capacity. As part of this process, CSA was renamed Ternium Brasil Ltda. and tkSI was absorbed by Ternium S.A.'s fully-owned subsidiary, Ternium Internacional España S.L.
On July 3, 2023, Ternium Investments and Ternium Argentina, together with TenarisConfab, acquired from the NSC Group, pro rata to their then participations in the T/T Group, 68.7 million ordinary shares of Usiminas, increasing Ternium’s participation in the Usiminas control group to 51.5%. A new shareholders’ agreement was entered into as a result of the transaction, pursuant to which the T/T Group (formed by Ternium Investments, Ternium Argentina and Tenaris’ subsidiary Confab Industrial) has the right to nominate a majority of the members of Usiminas’ board of directors, the CEO and four other members of Usiminas’ board of officers.

We began to fully consolidate Usiminas in July 2023.
B.    Business Overview
Our Business Strategy
Three main drivers compose Ternium’s business strategy: a focus on sophisticated value-added products, the pursuit of strategic growth opportunities and a relentless quest for competitive industrial operations. Ternium aims to enhance stakeholder value by further consolidating its position as a leading steel producer in Latin America and a strong player in the Americas, while increasing its differentiation and strengthening its competitiveness.
We believe Ternium has built competitive advantages in its main steel markets. Our industrial presence and network of distribution centers and commercial offices increase Ternium’s ability to offer differentiated logistics and stock management services. In addition, our integrated connectivity platform covering the entire customer relationship process enables Ternium to provide a better and faster response to its customers’ needs.
Ternium works together with small and medium-sized customers and suppliers in Argentina and Mexico, through the ProPymes program, to help them prosper. The development of SMEs and a collaborative industrial network have strengthened Ternium’s value chain. This effort has led to a virtuous cycle of improved competitiveness, increased exports and import substitution of manufactured products.
Ternium’s differentiation initiatives have also included investments in state-of-the-art technologies. As part of this strategy, Ternium Mexico has built its industrial center in Pesquería, Mexico (the “Pesquería Industrial Center”), which currently comprises a hot-rolling mill, a cold-rolling mill, two galvanizing facilities, a painting line, a push-pull pickling line and finishing facilities. In 2022, Ternium began the deployment of a new downstream project in the Pesquería Industrial Center. The project includes a push-pull pickling line and new finishing lines, already commissioned, and a hot-dip galvanizing line and a cold-rolling mill expected to begin operations by the end of 2025. Mexico has a competitive and innovative manufacturing sector and its favorable geographic location provides a competitive logistics base to reach every major market. These projects are consistent with Ternium’s strategy to strengthen its competitive position in order to replace imports in the Mexican market, and better serve its customers with a broader and more technologically advanced product portfolio. Complementing its processing technology upgrade, Ternium has expanded its product research and development infrastructure in order to enhance its capabilities and speed up the development of a broader product portfolio, particularly in the high-end steel segment, to better serve its industrial customers.
In addition, Ternium is building new steel slab-making facilities in the Pesquería Industrial Center. The new facilities, consisting of an electric-arc-furnace-based steel shop and a DRI module, are expected to produce the highest specification steels, necessary for the most demanding applications of the automotive industry, and to comply with USMCA's melted and poured rules of origin. Mexico has an attractive steel market with significant demand for advanced steel products, and foreign steel producers cover approximately half of the flat steel demand in the country. We believe that Ternium is well positioned in Mexico to compete with foreign producers and gradually substitute imports, as we have built a solid differentiation strategy, supported by Ternium’s unique industrial presence, as well as by its market competitiveness.
In Brazil, the second largest steel market in Latin America, Usiminas is one of the main producers of flat steel products. The country’s manufacturing sector accounts for a significant share of Usiminas’ sales, providing ample opportunities for the offering of value-added products and services. The appointment of Usiminas’ new management team in July 2023 took place in a transformational year for Usiminas, as it successfully relined its main blast furnace. Usiminas took other strategic steps, including putting out of operation one of its smaller blast furnaces and one of its coking facilities. Additional management decisions led to higher efficiency in the metallic charge in the upstream processes and lower fuel rate at the blast furnaces. These actions were part of a significant management initiative that is focused on the streamlining of Usiminas’ industrial system, with the aim at increasing its productivity, and will continue to be Usiminas’ focus throughout 2025.
Ternium Argentina has a significant presence in the Argentine steel market, the third largest in Latin America. The country’s manufacturing customers account for approximately half of the local flat steel consumption, providing ample opportunities for the offering of value-added products and services. Ternium has a solid differentiation strategy in Argentina built on its industrial integration in the country, which allows it to offer customized products and value-added services.
34


In Colombia, the fourth largest steel market in Latin America, Ternium expanded its capacity by adding a greenfield reinforcing bar facility in Palmar de Varela in 2020. Other facilities with finishing lines and service centers in Guatemala, El Salvador, Nicaragua and Costa Rica enable Ternium to maintain a vast presence in the region.
Focus on sophisticated steel products. The incorporation of new technologies, the development of new advanced steel products, and the integration of our industrial system are elements of a strategy aimed at increasing the participation of higher margin value-added products in Ternium’s sales mix. The Pesquería Industrial Center strengthened our positioning in the high-end market sector, expected to give way to a gradual substitution of imported steel in key industrial segments. The start-up of our new hot-rolling mill in 2021 represented a technological leap forward in Mexico’s steel production capacity. The new downstream project in the Pesquería Industrial Center is expanding the facility’s advanced high-strength and ultra high-strength steel production capabilities for the automotive, transport and heavy machinery industries. The new steel slab mill under development in the same site will integrate with aforementioned downstream facilities. Ternium’s steel bar and coil mill in Palmar de Varela, Colombia, is able to offer leading anti-seismic steel products for the Colombian construction sector, with improved resistance and toughness compared to those previously available in the market. For more information on Ternium’s product research and development efforts, see “—Research and Development; Product Development.” For further information on Ternium’s capital expenditures, see “—Capital Expenditure Program.”
Pursuit of strategic growth opportunities. We have a history of strategically growing our businesses through acquisitions and organic growth. We intend to continue identifying and actively pursuing growth-enhancing strategic opportunities to consolidate Ternium’s presence in its main markets and expand it to the rest of the Americas. We also intend to increase our industrial system integration, broaden our offerings of value-added products, and enhance our production and distribution capabilities. For example, in 2017 Ternium acquired a steel producer, renamed Ternium Brasil, with facilities located in the state of Rio de Janeiro, Brazil, with annual production capacity of 5.0 million tons of high-end steel slabs. With this acquisition, total crude steel production capacity of Ternium’s industrial system in 2017 increased to 12.4 million tons, or by approximately 70%. The acquisition of the Rio de Janeiro facility triggered the construction of the new hot-rolling mill in Pesquería, Mexico, with annual production capacity of 4.4 million tons which started up in 2021. This new facility enabled the integration of the Rio de Janeiro slab facility with Ternium’s industrial system in Mexico. Furthermore, the new upstream and downstream investment projects being deployed in the Pesquería Industrial Center are expected to place Ternium in an even better position to take advantage of attractive market opportunities like the nearshoring of supply chains. For further information on Ternium’s capital expenditures, see “—Capital Expenditure Program.”
Enhancement of Ternium’s competitive position. In addition to developing a full range of steel products and delivering differentiated services to Ternium’s customer base, we aim to enhance our competitive position by seeking excellence in operational performance. Our quest for operational excellence relies on the cross implementation of Ternium’s managerial, commercial and production best practices. Ternium has centralized industrial engineering, and automation, occupational, health and safety (OH&S), and environmental management areas. Focused on capacity utilization, quality and maintenance, this area facilitates the improvement of production processes through best practices, a coordinated deployment of new technologies and access to strong internal technical support.
Ternium’s broad range of value-added products, just-in-time delivery, inventory management and other services offered to customers in major steel markets are supported by our service center, distribution, sales and marketing networks. Ternium’s ample range of products and services can be offered to its customer base in a coordinated way, as its industrial system runs on a unified IT platform. Ternium has integrated its processes with those of its customers and suppliers through our digital marketplace, “Ternium Activo”. Most of our customers’ orders are placed through this platform, which helps them improve their management processes.
Environmental, Social and Governance
Ternium aims to create value for all its stakeholders. Our main efforts focus in the areas of occupational health and safety, environmental management, human resources, community relations, and the value chain, and aim at ensuring a sustainable operation in the long-term.

Improving our safety performance. The safety and well-being of our employees is our top priority and key to our success as a sustainable organization over time. We strive to create and sustain a safety culture aimed at safeguarding our employees' well-being. OH&S management and risk assessment are integrated into our business processes and are reflected in Ternium's OH&S policy. OH&S performance is included in the managers' integrated set of objectives. Senior managers lead every initiative aimed at forging our OH&S culture. We design strategies to align our culture with our OH&S vision. We seek to engage our employees, customers and contractors in order to deploy our vision and targets, managing our production processes safely and implementing an effective communication.

Through our “Safety First” program, safety behavior has been placed at the cornerstone of our culture. We have dedicated safety management teams that evaluate facilities and processes with an ample view, and design plans to mitigate risks.

Minimizing our environmental footprint. The protection of the environment is a fundamental value for Ternium. Our Environmental and Energy Policy expresses our commitment to the preservation of the environment. Ternium’s steel and mining operations are subject to laws and regulations to protect the environment, including the use of land, air emissions, wastewater treatment and discharge, the use, handling, and disposal of hazardous or toxic materials, and the handling and disposal of waste. Ternium’s corporate Environmental and Energy Policy requires that each of its business units comply with applicable environmental laws and regulations. We aim at achieving the highest standards of environmental performance, as a basis to ensure a sustainable development, and encourage our supply chain to embrace these principles.

Our environmental performance leans on an environmental and energy management system encompassing every production unit. We audit and certify our systems and procedures on a regular basis, which results in updates to our environmental management processes and the identification of improvement opportunities. Systems are certified under the ISO 14001 environmental management norm in all steel making and most processing facilities and under the ISO 50001 energy management norm in most top energy consuming operations. We are in the process of incorporating additional facilities to our ISO 50001 certification scope.

Another element for supporting the preservation of the environment is management supervision. Monthly, the Industrial, Environmental, Health and Safety Management Committee, led by our Chief Executive Officer (the “Chief Executive Officer”), gathers to review and discuss our environmental and safety performance. We consistently invest in environmental improvement projects, and are deploying a medium-term plan that is mainly focused on strengthening infrastructure in connection with particulate matter emission control, material efficiency and water quality control at the primary areas of our operations.

For further information on environmental regulations, see Item 4. “Information on the Company —B. Business Overview — Regulations - Environmental Regulation”. For a description of some of the risks associated with the environment, health and safety, see Item 3. “Key Information—D. Risk Factors.”

Realizing our people’s full potential. We work constantly towards the consolidation of an organization that offers equal opportunity and treatment, and that promotes industrial and technological excellence. We believe that our performance is dependent on the development of personnel competences and skills for each position in the company, and in a careful planning of succession and continuity processes. In this regard, we have centralized personnel training activities in Ternium University and Usiminas’ Corporate University, and we have a career development program and a succession program for key positions.

We have adopted policies on Human Rights and Diversity and Work Environment Free of Harassment. We aim to foster a workplace environment that attracts and develops talents across all genders, nationalities, generations, cultures, religions, and backgrounds, respecting and valuing individual differences. Ternium’s Code of Conduct prohibits unlawful discrimination in employment relations and ensures that every person has the right to apply for employment with us or to be considered for a new position strictly based on the skills required for such task.

Helping communities thrive. We believe that an industrial project like ours can only be sustainable if community and industry grow together. This is the principle guiding our community programs, which focus on four main fields:

-    Education. We are convinced that education is the key to prosperous community growth. Therefore, we have developed and ran educational programs covering the entire school cycle, from elementary to post-graduate, helping children and youngsters to fulfill their potential and become active contributors to society. Our programs include the Roberto Rocca Technical Schools, the Roberto Rocca Technical Gene, the Roberto Rocca After School Program and Roberto Rocca Scholarships.

-    Culture. As a multi-cultural and multi-lingual company, we enrich and broaden people’s cultural horizons in communities near our facilities, including by promoting cultural activities. Our programs include the Film Festival and the Photo Library, together with Instituto Usiminas’ initiatives.

-    Volunteer work. We encourage our employees to volunteer for community activities with a special focus on refurbishing schools, aimed at helping those in need and cultivating pride and integration in our communities. With this purpose, we developed the Volunteers in Action program.
36



-    Health. We seek to improve people’s quality of life and foster welfare. With this purpose, we fund infrastructure projects and improvements at hospitals and health care centers near our facilities.

Abiding by these general directives, our programs have been designed to be implemented at local level, taking into account the particular circumstances of each community where we operate.

Strengthening our value chain. We offer support to small and medium size enterprises (SMEs) through ProPymes, a program that provides a variety of services including training, industrial assistance, institutional assistance, commercial support and financial aid. The ProPymes program fosters the development of the industrial value chain in Mexico and Argentina, and helped create an industrial network that encourages the professionalization and quest for excellence of SMEs which, based on knowledge sharing, reciprocal learning and exchange of experiences, aims at the implementation along the value chain of the best practices utilized in the industry.

Integrity. We believe integrity is key to our long-term sustainability. With ethical behavior and compliance with law as a core value, we continuously work on building a corporate culture of transparency. The company has adopted a Code of Conduct, which has recently been updated, incorporating guidelines and standards of integrity and transparency that apply to all directors, officers and employees. As far as the nature of each relation permits, the principles described in the Code of Conduct also apply to relations with our contractors, subcontractors, suppliers and associated persons.

The Code of Conduct also includes guidelines related to the promotion of a healthy and safe workplace environment, respect for human and labor rights, the protection of the environment, our commitment to fair, honest and transparent competition, and the protection of data privacy of our employees and third parties with whom we conduct business. The company has also adopted a Code of Ethics for Senior Financial Officers to supplement its Code of Conduct, which applies specifically to the Chief Executive Officer, Ternium S.A.'s chief financial officer (the "Chief Financial Officer"), Ternium S.A.'s chief accounting officer or controller, or other persons performing similar functions. In addition, the company has adopted a Transparency Policy governing relationships with third parties, a Policy on Business Conduct, a Code of Conduct for Suppliers, an Anti-fraud Policy, a Policy on Securities Trading, a Policy on Financial and Accounting Controls, and a Policy on Personal Data Protection. As a condition for employment, all employees must acknowledge and commit to comply with Ternium’s Code of Conduct and eligible employees (salaried employees and managers, excluding supervisors) must acknowledge and commit to comply with Ternium’s Policy on Business Conduct.

Steel products
Slabs, billets and round bars: These products are semi-finished steel forms with dimensions suitable for its processing into specific product types. Slabs are processed into hot-rolled flat products. The use of slabs is determined by their dimensions and by their chemical and metallurgical characteristics. Billets are processed into long steel products, such as wire rods, bars, and other shapes. Round bars are processed into seamless tubes.
Plates: These products are used in a variety of applications in infrastructure, shipbuilding, civil construction (including bridges, sheds and buildings), maritime platforms, large diameter tubes, road and mining machinery and equipment, sugar and alcohol plants and power generation plants, including wind towers. Plates can be heat treated depending on the desired application.
37


Other hot-rolled flat products: Hot-rolled flat products are used by a variety of industrial consumers in applications such as the manufacturing of wheels, auto parts, pipes, gas cylinders and containers. They are also directly used for the construction of buildings, bridges and railroad cars, chassis of trucks and automobiles, and agricultural machinery. Hot-rolled flat products can be supplied as coils, strips or as sheets cut to a specific length. These products also serve as inputs for the production of cold-rolled products. Merchant bars include specific shape features, such as rounds, flats, angles, squares and channels, which are used by customers to manufacture a wide variety of products such as furniture, stair railings and farm equipment. Reinforcing bars (rebars) and stirrups, obtained from the mechanical transformation of rebars, are used to strengthen concrete highways, bridges and buildings. Rods are commonly drawn into wire products or used to make bolts and nails. Wire rod can be produced in different qualities according to customers’ demands.

Cold-rolled products: Cold-rolled products are applied mainly to the automotive, home appliance and capital goods industries, as well as to galvanizers, steel drum manufacturers, distributors and service centers. Cold-rolled coils are sold as coils or cut into sheets or blanks to meet customers’ needs. These products also serve as inputs for the production of coated products.

Coated products: Galvanized sheets are produced by adding a layer of zinc to cold-rolled coils, which are afterwards cut into sheets. Galvanized sheets are used in the automotive, construction, home appliances and energy industries. Galvanized coils can also be further processed with a color coating to produce pre-painted sheets, resulting in a product that is mainly sold for building coverings, manufacturing of ceiling systems, panels, air conditioning ducts, refrigerators, air conditioners, washing machines and several other uses. Ternium also offers a distinctive type of galvanized product with coating composition that contains approximately 55% aluminum and 44% zinc to improve product performance for the construction industry, including rural, industrial and marine sites. Tinplate, given its resistance to corrosion and its mechanical and chemical characteristics, is mainly sold to the packaging industry for food canning, sprays and paint containers. Tinplate is produced by coating cold-rolled coils with a layer of tin.
Roll-formed and tubular products: These products include tubes for general use, structural tubes, tubes for mechanical applications, conduction tubes, conduction electrical tubes, oil tubes and pre-engineered metal building systems. Tubular products, uncoated or galvanized, have applications in several sectors, including home accessories, furniture, scaffolding, automotive, bicycles, hospital equipment, posts for wire mesh garden and poultry tools, handrails, guard-rails, agricultural machinery, industrial equipment, conduction of water, air, gas, oil, high-pressure liquids and special fluids, internal building electrical installations, road implements, irrigation pivots and conveyor belts rollers. Beams, including C and Z section steel profiles (purlings) and tubular section beams, are obtained by roll-forming of steel strips and have applications in window frames, stilts, mainstays, crossbeams, building structures, supports, guides and crossbars for installing windows, doors, frames and boards. Other products include insulated panels, roofing and cladding, roof tiles and steel decks. Obtained from the mechanical transformation of flat steel, uncoated, galvanized or pre-painted, these products are used mainly in the construction industry in warehouses, commercial and industrial refrigeration installations, grain storage, poultry and porcine confinement facilities, roofing and side walls for buildings, and terraces and mezzanine floorings. Pre-engineered metal building systems are steel construction systems designed for use in low-rise non-residential buildings, and are constructed from the mechanical transformation of flat steel such as frames, secondary steel members, roofs and walls panels, as well as finishing and accessories.
Other products: Other products include mainly electricity and pig iron. Pig iron is a semi-finished product obtained in the blast furnace that is mostly used as metallic charge in the steel shop for the production of crude steel, and also marketed to other steel producers and to manufacturers of iron-based cast products.
Within each of the basic product categories, there is a range of different “items” of varying qualities and prices that are produced either to meet the particular requirements of end users or sold as commodity items.
Iron ore products
Lumps, concentrates (sinter feed and pellet feed fines) and pellets: These products are raw materials used for the production of steel. Lump ore is coarse ore with a diameter of between 32 and 6.3 millimeters, sinter feed is iron ore with a diameter of between 6.3 and 0.15 millimeters and pellet feed is iron ore with a diameter of less than 0.15 millimeters.

Lump iron ore is used in the production of steel without any further process. The sinter feed has to be agglomerated via a sintering process to enable its use in the blast furnace as sinter. The pellet feed has to be pelletized to enable its use in the blast furnace or DRI processes. Pellet feed can also be sinterized. In Mexico, Las Encinas and Peña Colorada ship most of the pellets to Ternium Mexico’s steelmaking facilities and they also market non-pelletizable iron ore fines, if any, to other steel manufacturers.
38


In Brazil, Mineração Usiminas ships lumps and concentrates to Usiminas’ steel manufacturing operations, and ships mainly concentrates to other steel manufacturers.

Location of Las Encinas and Consorcio Peña Colorada’s Active Mines
Miningmap2023.jpg
Las Encinas
Las Encinas produces iron ore pellets and magnetite concentrate in Mexico. At present, Las Encinas operates the Aquila and Palomas open pit mines located in Michoacán and Jalisco, Mexico, respectively. Las Encinas has three crushing plants located close to each of the Aquila, the El Encino and the Palomas mines, the latter operated under a lease agreement, and a concentration and pelletizing plant located in Alzada, Colima, Mexico. Its major processing facilities (crushing, concentration and pelletizing facilities) include two primary crushers and a dry cobbing plant located in the Aquila mine, a crushing plant, which includes two primary crushers and pre-concentration with magnetic pulleys located at the El Encino mine, and a semi-mobile crushing plant, which includes primary crushers and pre-concentration with magnetic pulleys located at the Palomas mine, and horizontal and vertical ball mills and several stages of magnetic separation in the Alzada facilities. Las Encinas has two operational tailings dams in Alzada and an idled tailings dam located in Cerro Náhuatl.

The iron ore pre-concentrate is transported from the Aquila mine to a transfer station at Tecoman, Colima, by truck and from Tecoman to the Alzada facilities by rail and truck for processing in the concentration plant (located at approximately 160 kilometers from the Aquila mine). The iron ore extracted from the Palomas mine is currently processed in a crushing facility in the mine, and the crushed iron ore is transported from the Palomas mine to the Alzada facilities by truck for processing in the concentration plant in Alzada (located at approximately 60 kilometers from the Palomas mine). In addition, our plant located in Alzada may receive, from time to time, magnetite iron ore purchased by Las Encinas from other local concessionaires. The iron ore pellets produced in the Alzada facilities are transported by rail to Ternium Mexico’s integrated facilities in Monterrey and Puebla, Mexico. The Aquila, El Encino and Palomas operations and the Alzada facilities receive electrical power from the Comisión Federal de Electricidad ("CFE"), the Mexican state-owned electric utility company.

Active mines

At the Aquila site, Las Encinas holds all the mining rights for the extraction of iron ore. The Aquila operations (including an open pit mine and crushing facilities) stand on 586 hectares, which are leased to Las Encinas by the local community of San Miguel de Aquila. The lease agreement allows Las Encinas to perform all mining activities, including the extraction of iron ore, necessary to exploit the ore located in mining rights granted to Las Encinas by the Mexican federal authorities until the permanent closure of the mine. Las Encinas has operated this mine since 1998.

49


Aquila is a mine composed predominantly of magnetite ore with hematite traces, and sulphides, silicates and carbonates gangues. The form of mineralization is massive and disseminated (hornfels, endoeskarn), with mineralized breccia. The mine site is hosted along to a regional fault, between an intrusive granodiorite and limestone, and the shape of the deposit is a northeast-southwest mineralization, mainly controlled by geological structures.

At the Palomas Mine, Las Encinas holds mining rights for the extraction of iron ore over 376 hectares. The Palomas operations (an open pit mine) stand on an area owned by Las Encinas, which started operating this mine in 2017.

The Palomas mine is a deposit iron skarn hosted in calcareous and granitic rocks with different kind halos of alteration grade. Mineralization is massive, bordered by disseminated mineral. The ore body is situated in concordant tabular horizons with a northwest and southeast-oriented pseudo stratification and northeast-oriented dip. The mineralization is predominantly magnetite ore with hematite traces. The gangue mineral is composed of garnet, pyrite and calcite. The surrounding rocks are skarn (calcareous protolyte, clayey calcareous and Cretaceous sandy) or hornfels (clayey protolyte). The stratigraphic sequence is affected by dyke intrusions of monzonite and granite composition.

Mineral reserve estimates at Las Encinas mines are based on a long-term iron ore reference price of $90 per dry metric ton for 62% ferrous CFR China, adjusted for grade, logistics, and other adjustments. Mineral resources are constrained within a Lerch & Grossmann pit shell, designed using the reference price for mineral reserves.

Areas under exploration

Las Encinas holds mining rights over other areas scattered throughout Michoacán, Jalisco and Colima, Mexico. Las Encinas has developed and may continue pursuing the development of small to mid-sized mining operations similar to Palomas, as a way to diversify its sources of iron ore and to make effective use of its mining rights in the region.

Exhausted mines

The El Chilillo open pit mine was operated until 2015. The El Chilillo mineral reserves were exhausted, the mine’s operations were suspended and the land returned to the owners. Ternium has already completed the requisite restoration works and has filed the applicable report with the environmental authority.

The El Encino open pit and underground mine was operated until 2011. The El Encino mineral reserves were exhausted and the mine’s operations have been suspended. Ternium continues to evaluate the steps required to proceed with its permanent closure. The crushing and transfer facilities at El Encino are still in operation and will remain active to receive, process and transfer to the Alzada pelletizing plant iron ore that Las Encinas buys from time to time from other local concessionaires.

The Cerro Nahuatl open pit mine located in Colima, Mexico, operated until 2008. The Cerro Nahuatl mineral reserves were exhausted and the mine’s operation has been suspended. Ternium is currently following the steps required to proceed with its permanent closure.

Consorcio Peña Colorada
Consorcio Peña Colorada, a company owned 50% by Ternium and 50% by ArcelorMittal S.A. ("ArcelorMittal"), produces iron ore pellets and magnetite concentrate in Mexico. Consorcio Peña Colorada operates the Peña Colorada open pit mine as well as a concentrating facility and a two-line pelletizing facility. Consorcio Peña Colorada owns part of the property where its mine and processing facilities stand, and leases 1,204 hectares adjacent to the mine to store waste dump material and, in the future, to mine mineral reserves as part of the regular short-term and long-term life of mine plan.

Consorcio Peña Colorada has operated since 1974 and holds mining rights over 39,980 hectares. The Peña Colorada mine is a complex polyphase iron ore deposit. Several magmatic and hydrothermal events produced iron mineralization as skarns or skarnoids, and late dikes and faults that crosscut the mineralized bodies. The main mineralization events are a massive ore body and a disseminated ore body, within polymictic breccia zones. Mineral reserve estimates at the Peña Colorada mine are based on a long-term iron ore reference price of $70 per dry metric ton for 62% ferrous CFR China, adjusted for grade, logistics, and other adjustments. Mineral resources are estimated based on the same long-term price forecast used for mineral reserves, increased by a revenue factor of 1.30 and adjusted upwards or downwards for mine specific factors and further adjusted for grade, logistics and other modifying factors.

The concentration plant is located at the mine in Minatitlán, Colima, and the pelletizing plant is located near the Manzanillo seaport on the Pacific coast in Colima, 50 kilometers from Minatitlán. Consorcio Peña Colorada’s major processing facilities include a primary crusher, two autogenous mill, horizontal and vertical ball mills, several stages of magnetic separation and two pelletizing lines.
50


The concentrate is sent as a pulp through a 45 kilometers-long pipeline from the mine and mineral processing plant in Minatitlán to the pelletizing plant in Manzanillo.

Consorcio Peña Colorada has an operational tailings dam in Arrayanal, Colima, and a tailings dam in the process of closure located in Guásimas, Colima, with limited use. A paste plant operates near the Arrayanal dam to help increase the solid content of tailings. The Peña Colorada mine and the pelletizing plant receive electrical power from CFE.

Ternium is required to buy from Consorcio Peña Colorada half of the mine’s annual production. For further information, see Item 4. “Information on the Company—B. Business Overview—Raw Materials, Slabs, Energy and Other Inputs—Mexico—Iron Ore.” Iron ore concentrate and pellets sold to Ternium are shipped by rail from the mine to Ternium’s facilities in Mexico or exported to third parties through the Manzanillo port.

Iron ore mineral resources and mineral reserves
In 2024, net sales of Ternium’s mining segment in Mexico represented 2.9% of the company’s consolidated net sales and were totally used internally for steel making. As of December 31, 2024, the property, plant and equipment value of Ternium’s mining segment in Mexico represented 5.4% of the company’s consolidated property, plant and equipment value. None of our iron ore mines is considered to be material on an individual basis.

The estimates of mineral resources and mineral reserves at our mines and projects have been prepared by qualified persons. The 2024 mineral resource and mineral reserve estimates at the Aquila and Palomas mining properties were audited by SRK Consulting (Peru) S.A. The 2024 mineral resource and mineral reserve estimates for the Peña Colorada mine were audited by SLR Consulting (Canada) Ltd. In addition, external qualified professionals and companies collaborate with management to validate findings in relevant areas such as geotechnics, geology, and mining design.

Las Encinas and Consorcio Peña Colorada have in place quality control and quality assurance processes and procedures to estimate mineral resources and mineral reserves. Las Encinas and Consorcio Peña Colorada adopted internal procedures that describe the systems and processes to effectively manage mining activities. These procedures follow industry practices, are managed by experienced and qualified technical experts, and are regularly reviewed and updated.

In the field, information is managed by experienced professionals who follow specified procedures. Data derived from exploration drilling, field sampling, process tests, and product quality is subject to thorough sample security and integrity protocols, field and laboratory quality assurance and quality control processes, as well as data validation procedures. Quality control processes and procedures vary depending on the specific nature of the drilling, sampling program or laboratory analysis. Operational and historical data is subject to internal validation procedures. Compliance with such procedures is verified through internal database audits and spatial and statistical analysis.

Mineral resource and mineral reserve estimations are subject to normal industry risks, including metal prices, economic and market risks, metallurgical performance, and geological modeling. For geological risk, Ternium has modeling and estimation procedures following mining industry best practices, including drilling, core logging, sampling, and density protocols. For information on risks relating to the determination of mineral resources and mineral reserves, see “Risks Relating to Ternium’s Mining Activities - Ternium’s resource and reserve estimates may differ materially from actually recoverable mineral quantities, or its estimates of mine life may prove inaccurate; and market price fluctuations and changes in operating and capital costs may render certain ore reserves uneconomical to mine or cause Ternium to revise its resource or reserve estimates.”

Iron ore mineral reserves

The table below details Ternium’s estimated proven and probable iron ore mineral reserves in Mexico as of December 31, 2024. The classification of the iron ore mineral reserve estimates as proven or probable reflects the variability in the mineralization at the selected cut-off grade, the mining selectivity and the production rate and ability of the operation to blend the different ore types that may occur within each deposit.

(1)Saleable production consists of a mix of direct shipped ore, concentrate, pellet feed and pellet products which have an iron content of approximately 65% to 66%.
(2)Mine life is calculated assuming the full utilization of the pellet plant and corresponds to the duration of ore reserve estimates only.
(3)2024 includes exclusively the Aquila and Palomas mines. Run of mine production in 2024 was 3.4 million tons and in 2023 was 1.9 million tons.
(4)Run of mine production in 2024 was 3.9 million tons and in 2023 was 6.4 million tons. Reported figures are for Peña Colorada’s operation at Ternium’s 50% ownership interest in Consorcio Peña Colorada. The year-over-year decrease in run of mine production in 2024 compared to 2023 was due to deferrals in mining preparation, as the process for the obtention of an environmental permit for tailings disposal was lengthier than expected.
The mineral reserve estimates were prepared in compliance with the requirements of SEC rules, under which:
•Reserves are the part of a mineral deposit that could be economically and legally extracted or produced at the time of the reserve determination.
•Proven reserves are reserves for which (a) quantity is computed from dimensions revealed in outcrops, trenches or working or drill holes; grade and/or quality are computed from the results of detailed sampling; and (b) the sites for inspection, sampling and measurement are spaced so closely and the geologic character is so well defined that size, shape, depth, and mineral content of reserves are well established.
•Probable reserves are reserves for which quantity and grade and/or quality are computed from information similar to that used for proven reserves, but the sites for inspection, sampling and measurement are farther apart or are otherwise less adequately spaced. The degree of assurance, although lower than that for proven reserves, is high enough to assume continuity between points of observation.
The demonstration of economic viability is established through the application of a life of mine plan for each operation or project providing a positive net present value on a cash forward-looking basis. Economic viability is demonstrated using forecasts of operating and capital costs based on historical performance, with adjustments based on planned process improvements, changes in production volumes and in fixed and variable proportions of costs, and forecasted fluctuations in costs of raw material, supplies, energy and wages. Mineral reserve estimates are updated annually in order to reflect new geological information and current mine plan and business strategies. Our mineral reserve estimates are of in-place material after adjustments for mining depletion and mining losses and recoveries, with no adjustments made for metal losses due to processing. For a description of risks relating to mineral reserves and mineral resource estimates, see Item 3. “Key Information—D.Risk Factors—Risks Relating to Ternium’s Mining Activities—Ternium’s reserve and resource estimates may differ materially from actually recoverable mineral quantities, or its estimates of mine life may prove inaccurate; and market price fluctuations and changes in operating and capital costs may render certain ore reserves and resources uneconomical to mine in the future or cause Ternium to revise its reserve or resource estimates.”

Our mining leases are of sufficient duration (or convey a legal right to renew for sufficient duration) to enable all mineral reserves on the leased properties to be mined in accordance with current production schedules.

Our mineral reserves may include areas where some additional approvals remain outstanding but where, based on the technical investigations we carry out as part of our mine planning process and our knowledge and experience of the approvals process, we expect that such approvals will be obtained as part of the normal course of business and within the timeframe required by the current life of mine schedule.

Changes in iron ore mineral reserve estimates (2024 versus 2023)

Las Encinas’ iron ore mineral reserve estimates as of December 31, 2024 were 20 million tons on a run-of-mine basis (with an average magnetic iron grade of 30%), decreasing by 5 million tons (with 2 percentage points lower magnetic iron grade) compared to those recorded as of December 31, 2023. The year-over-year decrease was mainly due to the depletion of iron ore mineral reserves in 2024 and a decrease in iron ore mineral reserve estimates based on an updated block model and the incorporation of additional drill hole information.

Peña Colorada’s iron ore mineral reserve estimates as of December 31, 2024 were 122 million tons on a run-of-mine basis (with an average magnetic iron grade of 20%) increasing by 7 million tons (with 1 percentage point lower magnetic iron grade) compared to those recorded as of the end of 2023. The year-over-year increase was mainly due to the depletion of iron ore mineral reserves in 2024 partially offset by an increase in iron ore mineral reserve estimates based on a cut-off grade reduction. Reported figures are for Peña Colorada’s operation at Ternium’s 50% ownership interest in Consorcio Peña Colorada.

Changes in iron ore mineral resource estimates (2024 versus 2023)
Las Encinas’ inferred iron ore mineral resource estimates as of December 31, 2024 were 14 million tons (with an average magnetic iron grade of 31%), increasing by 2 million tons (with 2 percentage points lower magnetic iron grade) compared to those recorded as of December 31, 2023. The year-over-year change was mainly due to the incorporation of iron ore mineral resources in the context of an intensive drilling campaign in the Aquila mine. However, estimation works under development in the Aquila mine could result in the future in further changes in iron ore mineral resources. For information on risks relating to the determination of mineral resources and mineral reserves, see “Risks Relating to Ternium’s Mining Activities - Ternium’s resource and reserve estimates may differ materially from actually recoverable mineral quantities, or its estimates of mine life may prove inaccurate; and market price fluctuations and changes in operating and capital costs may render certain ore reserves uneconomical to mine or cause Ternium to revise its resource or reserve estimates.”

Peña Colorada’s measured and indicated iron ore mineral resource estimates as of December 31, 2024 were 42 million tons (with an average magnetic iron grade of 22%), increasing by 3 million tons (with 2 percentage points lower magnetic iron grade) compared to those recorded as of December 31, 2023. The year-over-year change was mainly due to an increase in iron ore mineral resource estimates, based on a cut-off grade reduction, the incorporation of additional drill hole information and an updated estimation methodology. Reported figures are for Peña Colorada’s operation at Ternium’s 50% ownership interest in Consorcio Peña Colorada.

In 2021, Mineração Usiminas implemented a dry stacking system to process tailings and, accordingly, tailings dams are no longer used. Mineração Usiminas had two tailings dams that were declared decommissioned, Somisa and Central, after it completed a closing procedure and fulfilled the legal requirements for obtaining such declaration. As of December 31, 2024, Mineração Usiminas had one inactive remaining tailings dam, Samambaia 0, with deposits volume of 8 million cubic meters. Samambaia 0 was built downstream and remains closed. In addition, Mineração Usiminas has initiated the required legal steps to obtain the decommissioning declaration by Minas Gerais’ authorities for its Samambia 0 tailings dam.
In addition to the Sambambaia 0 iron ore tailings dam, Mineração Usiminas has a sediment containment structure, the Oeste dike. This structure meets the requirements of the Política Nacional de Seguridad de Barragens, the national policy for dam safety. The Oeste dike is monitored by the company's geotechnical structure management systems, which comply with all applicable legal requirements, including the external audit carried out by an independent company.

Mineração Usiminas operates one crushing/classification plant located in the Leste mine, and three concentration plants located in the Oeste and Central mines. Its major processing facilities include crushers, mill, screens, cyclones, spiral classifier, spiral concentrators, jigs, magnetic concentrators, flotation cells, flotation columns, filters and a decanter.
Iron or lumps, sinter feed and pellet feed are transported by truck from the mines to railroad terminals. The iron ore destined to Usiminas’ Ipatinga unit is transported by railroad from the Modal railroad terminals. Sinter feed and pellet feed destined to offshore customers, mainly from Asia, is transported by railroad to ports in the Atlantic Ocean coast. The facilities receive electrical power from CEMIG, a local electric utility company.
Active mines

Mineração Usiminas currently operates three iron ore mines: Oeste, Central and Leste. The Oeste, Central and Leste iron ore mines, together with their iron ore processing facilities, stand on 1,905 hectares, 1,250 hectares and 445 hectares, respectively. The environmental licences in force allow Mineração Usiminas to perform all mining activities necessary to exploit the ore located in every area where it has mining rights, until the permanent closure of the mines. Mineração Usiminas has operated these mines since 2010.

The Oeste and Central mines are composed predominantly of siliceous itabirite (friable, semi-compact and compact itabirite). The mineralization occurs as a tens of meters thick tabular or folded layers of banded iron formation. The mines are located on the iron formation which occurs between quartzite and phyllites in a kilometric mountain range.

The Leste mine is composed predominantly of layers of siliceous itabirite (friable, semi-compact and compact itabirite) with interdigitated lenses of magnetite itabirite, which changes laterally to dolomite, and portions of clayey iron formation that occurs close to the contact with the quartzites of the Cercadinho formation. This mine is also located on an iron formation, which occurs between quatzites and phyllites.

Mineral reserve and mineral resource estimates at Mineração Usiminas mines are based on an estimated long-term iron ore price of $85 per dry metric ton for 62% iron content CFR China, adjusted by grade and other chemical elements content.

Iron ore mineral resources and mineral reserves in Brazil
In 2024, Mineração Usiminas’ mining products shipments represented 3.1% of Ternium’s consolidated net sales. As of December 31, 2024, the property, plant and equipment value of Mineração Usiminas represented 4.0% of Ternium’s consolidated property, plant and equipment value. None of our iron ore mines is considered to be material on an individual basis.

The estimates of mineral resources and mineral reserves at our mines and projects have been certified by a qualified person with GE21 Consultoria Mineral Ltda (“GE21”) contracted by Mineração Usiminas.

Mineração Usiminas adopted internal procedures that describe the systems and processes to effectively manage mining activities. These procedures follow industry practices, are managed by experienced and qualified technical experts, and are regularly reviewed and updated.

In the field, information is managed by experienced professionals who follow specified procedures. Data derived from exploration drilling, field sampling, process tests, and end product quality is subject to thorough sample security and integrity protocols, field and laboratory quality assurance and quality control processes, as well as data validation procedures. Quality control processes and procedures vary depending on the specific nature of the drilling, sampling program or laboratory analysis. Operational and historical data is subject to internal validation procedures. Compliance with such procedures is verified through internal database audits and spatial and statistical analyses.

Mineral resource and mineral reserve estimations are subject to normal industry risks, including metal prices, economic and market risks, metallurgical performance, and geological modeling. For geological risk, Mineração Usiminas has modeling and estimation procedures following mining industry best practices, including drilling, core logging, sampling, and density protocols. For information on risks relating to the determination of mineral resources and mineral reserves, see Item 3. “Key Information—D.Risk Factors—Risks Relating to the Mining Activities - Ternium’s reserve and resource estimates may differ materially from actually recoverable mineral quantities, or its estimates of mine life may prove inaccurate; and market price fluctuations and changes in operating and capital costs may render certain ore reserves and resources uneconomical to mine or cause Ternium to revise its reserve or resource estimates.”

Iron ore mineral reserves in Brazil

The table below details Mineração Usiminas’ estimated proven and probable iron ore mineral reserves as of December 31, 2024. The classification of the iron ore mineral reserve estimates as proven or probable reflects the variability in the mineralization at the selected cut-off grade, the mining selectivity and the production rate and ability of the operation to blend different ore types that may occur within each deposit. Mineral reserves are reported as Run of Mine (ROM). References to tons in mineral reserve figures are to wet metric tons. To be able to process compact itabirites, Mineração Usiminas would need to deploy a new project that requires new equipment and facilities and significant capital expenditures. This project is currently under analysis and has not been yet approved. For information on risks relating to this investment, see Item 3. “Key Information—D.Risk Factors—Risks Relating to the Mining Activities - Inability to complete activities required to maintain iron ore and pellets production rates over time could increase Ternium’s steel production cost.”

Changes in iron ore mineral resource estimates (2024 versus 2023)
Friable itabirite iron ore mineral resource estimates as of December 31, 2024 decreased 11 million tons year-over-year to 298 million tons of measured and indicated mineral resource estimates and 55 million tons of inferred mineral resource estimates (with an average iron grade of 47% and 50%, respectively). The decrease in mineral resource estimates was due mainly to mineral resource depletion during the year. Inferred mineral resource estimates remained unchanged.
Compact itabirite iron ore mineral resource estimates as of December 31, 2024 decreased 2 million tons year-over-year to 1,292 million tons of measured and indicated mineral resource estimates and 293 million tons of inferred mineral resource estimates (with an average iron grade of 36% and 33%, respectively). The decrease in resource estimates was due to the use of compact itabirite in operating and waste disposal activities. Inferred mineral resource estimates remained unchanged.
Property, Plant and Equipment
Mineração Usiminas’ property, plants and equipment value as of December 31, 2024 amounted to $339.2 million.
Production process
Ternium specializes in manufacturing and processing finished steel products. In addition, Ternium extracts and processes iron ore and produces electricity.
Ternium’s facilities use different technologies and have different levels of integration. The basic inputs for steel production are iron ore, metallurgical coal and energy. Iron ore is used in three different formats: fines, lumps and pellets. Ternium’s steel production processes consume energy mainly in the form of natural gas, coal and electricity.
Iron ore extraction and processing. The iron production process begins with the extraction of iron ore from open pit mines owned and operated by Las Encinas and Peña Colorada in Mexico and Mineração Usiminas in Brazil. The mining process consists of removing the ore from the surface using explosives, loading it and transporting it by truck to the crushing facilities where it is crushed to a specified size.
After crushing, the ore goes through several stages of grinding and concentration. Grinding reduces the size of the ore, while concentration, using magnetic, densitometric and flotation methods, separates the iron from the tailings to produce iron ore concentrate. This process is carried out using water as an auxiliary element. Excess water is then recovered through a filtration process. The iron ore concentrate is then shipped to our steel mills and third parties.
After the filtering process and by leaving the necessary humidity, pellets are formed using pelletizing disks. Pellets are separated according to their size and are then hardened in ovens and shipped to the steel producing facilities.
58


Steel production. Ternium produces semi-finished steel in the form of thin slabs, slabs, billets and round bars through the blast furnace and the electric arc furnace methods.
Under the blast furnace method, which is used in Brazil and Argentina, iron ore pellets, lumps, sinter (a mixture of iron ore fines and limestone produced in sinter facilities) and coke (a solid residue obtained from the distillation of coal produced in coking batteries) are mixed in the blast furnaces in a process that melts and reduces the iron ore, obtaining pig iron. The molten pig iron is then mixed with steel scrap and other products in a basic oxygen furnace through a process that removes impurities from the pig iron by injecting pure oxygen at high pressure into the molten metal, burning-off carbon and other elements. The molten steel is then cast using the continuous casting method, into slabs.
Under the electric arc furnace method, which is used in Mexico and Colombia, the iron metal charge is heated with other elements to obtain molten steel. The molten steel is then cast, using the continuous casting method, into billets and thin slabs. The iron metal charge in the Apodaca and Manizales plants is steel scrap, and the iron metal charge in the Monterrey and Puebla plants is a mix of DRI and steel scrap. The DRI results from the conversion of pellets in the DRI modules. One of Monterrey’s DRI plants includes Hytemp® technology, which permits the hot discharge of the DRI to the electric arc furnace, generating significant energy savings and improving productivity.
Steel processing. Semi-finished steel is then processed into finished products using hot-rolling, cold-rolling, coating, tubing, paneling, slitting and cut-to-length facilities among other processes. In Mexico, Brazil and Argentina, Ternium processes steel slabs produced in Ternium Brazil and/or purchased in the marketplace, as in Mexico and Brazil its steel processing capacity is higher than its steel production capacity, and in Argentina its steel processing capacity utilization has been higher in recent years than its steel production capacity. Ternium may purchase hot-rolled, cold-rolled and coated products as well for further processing in its lines.
Thin-slabs, slabs and billets are processed in the hot-rolling mills in Mexico, Brazil, Argentina and Colombia to obtain hot-rolled products using different technologies. In the case of flat products, hot-rolled coils are obtained from thin or conventional slabs. Thin slab hot-rolling, a technology Ternium uses only in Mexico, requires less energy than conventional slab hot-rolling, as it does not require a roughing section at the mill and does not need to be reheated from room temperature to reach rolling temperature. In addition, in Brazil, Usiminas obtains plates from conventional slabs in a hot-rolled heavy plate line. In the production of long products, which is carried out in Mexico and Colombia, billets are reheated and taken to rolling temperature. The softened steel is processed in the rolling trains to obtain wire rods and rebars as finished long products and, depending on their final use, rebars can be further processed into stirrups and other customized shapes in our service centers in Colombia.
Depending on its final use, the hot-rolled coils are then heat-treated and/or pickled in Mexico, Brazil and Argentina, before being sent for sale as coils or cut into steel sheets. Alternatively, the hot-rolled coils may be sent to a cold-rolling mill where they are put under a deformation process at room temperature to reduce their thickness and obtain cold-rolled coils. Cold-rolled coils can be sold in crude form to the market (full hard) or processed in the reheating ovens, annealing bays and temper lines to modify their metallurgic and physical characteristics. The heat-treated products can be sold as coils or sheets or further processed by adding coatings.
Cold-rolled coils can be further processed into tinplate at Ternium Argentina’s facility (by adding a thin layer of tin), into galvanized or electrogalvanized sheets at several of Ternium’s facilities in Mexico, Argentina, the United States, Guatemala, and at Usiminas’ facilities (by adding a thin layer of zinc to the products through different processes) or into pre-painted products. Some of these products can be further processed into slitted, cut-to-length and tailor-made products according to customers’ needs at Ternium’s service centers, which are located in several countries. In addition, coated, cold-rolled and hot-rolled coils can be further processed into tubular products, such as welded pipes, insulated panels and architectural panels, among other customized products.

Competition
Steel
The steel industry operates predominantly on a regional basis, with large industry participants selling the bulk of their steel production in their home countries or regions, where they have natural advantages and are able to more effectively market value-added products and provide additional customized services. International trade of steel is also relevant, despite the limitations associated with transportation costs, as well as the restrictive effects of protective tariffs and other trade restrictions. Historically, several large steel manufacturers have merged with each other or acquired steel companies in other parts of the world. This wave of consolidation has resulted in a number of large, global producers with significant operations in several regions and/or continents, contributing to the increasing globalization of the steel industry. Considered as a whole, however, the steel industry still remains considerably fragmented, compared with market conditions characterizing certain of our suppliers and customers, e.g. iron ore suppliers and the automotive industry.

The main inputs for Ternium’s facilities are the following: in Mexico, slabs, iron ore, steel scrap, electricity and natural gas; in Brazil and Argentina, iron ore and metallurgical coal; and in Colombia, steel products, steel scrap and electricity. Below is a more complete description of the supply conditions for raw materials, slabs, billets, energy and other inputs at Ternium’s facilities in these countries. For a description of some of the risks associated with Ternium’s access to raw materials, slabs, energy and other inputs, see Item 3. “Key Information—D. Risk Factors—Risks Relating to the Steel Industry—Price fluctuations, shortages or disruptions in the supply of raw materials, slabs, energy and other inputs could adversely affect Ternium’s profitability and —Risks Relating To Ternium's Business—The physical risks resulting from climate change, including extreme weather conditions and shifts in weather patterns may adversely impact Ternium’s business.”

Ternium Mexico and Tenigal
In Mexico, the manufacturing of finished steel products relies on the supply of crude steel from its steelmaking facilities, which are based on the EAF technology, and on the purchase of steel slabs from third parties or from other Ternium subsidiaries. The mini-mill technology melts a variable combination of DRI and steel scrap to produce thin slabs, billets and round bars. The production process in Mexico requires extensive use of natural gas and electricity. Purchased slabs are the largest component of production costs; iron ore, scrap, electricity and natural gas costs are also significant.
Slabs. Ternium’s Mexican subsidiaries have some non-integrated steel processing facilities that consume large quantities of slabs purchased from third-party suppliers or from Ternium Brasil and, from time to time, Ternium Argentina. Slab consumption could vary significantly from year to year in accordance with market conditions. Our Mexican subsidiaries purchased, either from third parties or from other Ternium facilities, 5.8 million, 6.2 million and 5.1 million tons of slabs in 2024, 2023 and 2022, respectively. Slab purchase prices are market-based. A new wave of international sanctions against Russian steel companies that have not been affected by current sanctions in connection with the Russia-Ukraine war could result in increased restrictions in the availability of steel slabs for Ternium Mexico's operations.
Iron ore. As described under “—Production Facilities and Processes—Mining Production Facilities” above, in Mexico Ternium owns interests in two mining companies: 100% of the equity of Las Encinas and a 50% equity stake in Consorcio Peña Colorada.
68


Under our arrangement with Consorcio Peña Colorada, we are committed to off-take 50% of the annual production of the Peña Colorada mine. In 2024, 2.9 million tons of iron ore were shipped from these two companies to Ternium’s Mexican steel production facilities. In addition, from time to time, we purchase iron ore pellets from third parties. On average, we consume approximately 0.9 ton of iron ore to produce one ton of crude steel at our EAF facilities in Mexico.
Steel scrap. We source steel scrap from the Mexican market, through Ternium’s own steel scrap collecting and processing operations, and from the U.S. market. Steel scrap is purchased at market prices. On average, we consume approximately 0.5 tons of scrap to produce one ton of crude steel at our mini-mill facilities in Mexico.
Electricity. Electric arc furnaces consume large quantities of electricity. In Mexico, Ternium purchases electricity from Techgen S.A. de C.V., or Techgen, and CFE. Techgen owns a natural gas-fired combined cycle power plant in the Pesquería area of the State of Nuevo León, Mexico. Techgen is a joint venture company in which Ternium participates, and it contracts 78% of Techgen’s capacity of approximately 900 megawatts, or MW. As the capacity contracted by Ternium is significantly higher than the capacity currently required, Ternium resells unused electricity to the Mexican market. For further information on the Techgen investment, see “—C. Organizational Structure—Other investments—Techgen”. On average, we consume approximately 0.7 megawatts-hour, or MWH of electricity to produce one ton of crude steel at our mini-mill facilities in Mexico.
Natural gas. Natural gas is mainly used as a reducing agent for the production of DRI and for the reheating of slabs and billets before the hot-rolling process. Ternium has secured natural gas transportation capacity with Kinder Morgan and with Centro Nacional de Control del Gas Natural, the Mexican national center for natural gas control, on a private pipeline connecting the Pesquería Industrial Center with natural gas resources in the United States and on the Mexican natural gas transportation grid (Sistema de Transporte y Almacenamiento Nacional Integrado de Gas Natural), respectively. Ternium has also natural gas distribution agreements with Gas Industrial de Monterrey S.A. de C.V. ("GIMSA"), Compañía Mexicana de Gas S.A. de C.V. and Naturgy Mexico S.A. de C.V.
In addition, Ternium has two-year renewable agreements with NEG Natural S.A. de C.V. ("NEG"), a subsidiary of Mexican conglomerate ALFA, and with Maquarie Energy Mexico S. de R.L. de C.V. to supply natural gas to Ternium’s facilities in the Monterrey area of Mexico and to the Puebla unit, respectively. Natural gas prices in Mexico are mainly based on the Houston Ship Channel reference price plus transportation, distribution and service costs depending on the location of the delivery points in Mexico. On average, we consume approximately 8.1 million btu of natural gas to produce one ton of crude steel at our mini-mill facilities in Mexico.

Usiminas
Usiminas produces crude steel through the use of blast furnace technology. Usiminas’ manufacturing of finished steel products relies on the supply of steel slabs from its upstream facilities, and on the purchase of steel slabs from third parties and from Ternium Brasil. The principal raw materials used to produce steel are iron ore, metallurgical coal, pulverized coal and coke. The manufacturing process also requires significant quantities of electricity and natural gas.
Iron ore. As described under “—Production Facilities and Processes—Mining Production Facilities” above, Usiminas has a 70% equity participation in Mineração Usiminas. In 2024, 2.0 million tons of iron ore were shipped from Mineração Usiminas to Usiminas’ steel production facilities, representing 50% of its iron ore requirements. In addition, Usiminas purchases iron ore, in the form of pellets, under short-term/quarterly supply agreements with Vale, totaling 0.8 million tons in 2024. Usiminas’ geographic location provides favorable access to high quality iron ore produced in Brazil’s iron ore mines in the southeast region. Usiminas consumes approximately 1.6 tons of iron ore to produce one ton of crude steel.
Metallurgical coal and related materials. Usiminas obtains its coke through the distillation in its coke ovens of metallurgical coal and petroleum coke. The facilities require different types of coal to produce coke. Usiminas also purchases other coal qualities, able to be injected in the blast furnace, and coke. Coal and coke are purchased under long-term contracts and on the spot market from several major international suppliers based mainly in Australia, United States and Colombia. Prices under contracts are determined in accordance with market conditions. Petroleum coke is purchased from Petróleo Brasileiro S.A., or Petrobras. Usiminas consumes approximately 0.4 tons of metallurgical coal and third-party coke to produce one ton of crude steel.
Slabs. Usiminas has non-integrated steel processing facilities that consume large quantities of slabs. In addition, Usiminas’ integrated operations may require the purchase of slabs for downstream processing, to supplement its own production of crude steel, as it did in 2023 when its main blast furnace went through a relining process. Slab consumption can vary significantly from year to year in accordance with market conditions.
69


Usiminas purchased and processed, either from third parties or from Ternium Brasil, 1.6 million, 2.2 million and 2.0 million tons of slabs in 2024, 2023 and 2022, respectively. Slab purchase prices are market-based.
Electricity. Usiminas consumes large quantities of electricity for its manufacturing activities. A share of the electricity required by Usiminas is self-generated on site in its thermoelectric plant, which has an installed power capacity of 130 MW. This thermoelectric plant uses steam primarily generated from co-product gases obtained in the steelmaking process (blast furnace, coke oven gases and steel shop) enriched with natural gas. Actual power generation depends on the volume of co-product gases provided by the production process.
Usiminas purchases additional electricity to meet its requirements mainly from Engie Brasil Energia, Companhia Energética de Minas Gerais, or CEMIG, ENEL Brasil and Canadian Solar Brasil, under take-or-pay contracts that remain in effect until 2026. In addition, Usiminas’ Cubatão facility purchases electricity from CEMIG under a long-term supply agreement expiring in 2030. Also, Usiminas has a long-term supply agreement with renewable energy producer Canadian Solar Brasil for the supply of electricity, equivalent to 14% of Usiminas’ consumption, that expires in 2039. Usiminas consumes approximately 2.200 GWh/year of electricity.
Natural gas. Usiminas also consumes substantial volumes of natural gas, particularly to operate its steel plant and also to generate electricity in its thermoelectric plant in order to supply priority areas in the event of a power grid supply failure. Usiminas has one-year renewable contracts for the purchase of natural gas with Companhia de Gas de Minas Gerais, or GASMIG, and Companhia de Gás de São Paulo, or COMGÁS. Usiminas consumes approximately 35.000 MMBTU/day of natural gas.
Other inputs. At Usiminas’ facilities, White Martins Gases Industriais owns and manages on-site plants from where it supplies industrial gases for the steelmaking process under long-term agreements expiring in 2032. White Martins Gases Industriais also supplies hydrogen through road transportation for Cubatão’s cold-rolling process, under a long-term agreement expiring in 2027. Messer Gases Brasil supplies hydrogen through road transportation for Ipatinga’s cold-rolling and galvanizing processes, under a long-term agreement expiring in 2026.
Ternium Brasil and Ternium Argentina
Ternium Brasil and Ternium Argentina produce crude steel through the use of blast furnace technology. The principal raw materials used to produce steel are iron ore, metallurgical coal and, in Ternium Brasil, pulverized coal. The manufacturing process also requires significant quantities of electricity and natural gas.
Iron ore. Iron ore is purchased under long-term agreements from suppliers in Brazil. Prices under these contracts are determined in accordance with market conditions. Our main suppliers of iron ore, in the form of lumps, pellets and sinter feed fines, are LHG Mining Corumba S.A. and Vale, and to a lesser extent Samarco Mineração S.A. and Vetria Mineração S.A. Our geographic location in Brazil provides favorable access to high quality iron ore pellets, lumps and fines produced in Brazil’s iron ore mines in the Southeast Region mainly, and our geographic location in Argentina provides favorable access to high quality iron ore lump and fines produced in Brazil’s iron ore mines in the Pantanal Region (Mato Grosso do Sul state). In addition, Ternium Argentina’s steelmaking facility receives iron ore pellets and fines from ports located on Brazil’s ocean coast. We consume approximately 1.5 tons of iron ore to produce one ton of crude steel in Ternium Brazil and approximately 1.4 tons of iron ore to produce one ton of crude steel in Ternium Argentina.
Metallurgical coal and related materials. Ternium Brasil and Ternium Argentina obtain their coke through the distillation in their coke ovens of metallurgical coal and petroleum coke. The facilities require different types of coal to produce coke. In addition, Ternium Brasil purchases other coal qualities to inject in the blast furnace. Coal is purchased under short-term contracts and on the spot market from several major international suppliers based mainly in Australia and the United States. Prices under contracts are determined in accordance with market conditions. We purchase petroleum coke produced by oil companies in Argentina and Brazil. The volume purchased from each supplier mainly depends on the technical quality requirements of the blast furnace operations. We consume approximately 0.7 tons of metallurgical coal, pulverized coal and imported coke to produce one ton of crude steel in Ternium Brazil and 0.5 tons of metallurgical coal and petroleum coke to produce one ton of crude steel in Ternium Argentina.
Electricity. Ternium Brasil and Ternium Argentina consume large quantities of electricity for their manufacturing activities. The electricity required by Ternium Brasil is self-generated on site by its thermoelectric plant with an installed power capacity of 490 MW, with excess electricity production sold in the Brazilian wholesale market.
70


Most of the electricity required by Ternium Argentina is self-generated on site in the San Nicolás unit by a wholly-owned thermoelectric plant with an installed power capacity of 108 MW and by a new wind farm in Olavarría, inaugurated in the fourth quarter of 2024, with a nominal power capacity of 99 MW. The thermoelectric plants use steam primarily generated from co-product gases obtained in the steelmaking process (blast furnace and coke oven gases). Additional fuel requirements are covered with natural gas.
Natural gas. Ternium Brasil and Ternium Argentina also consume substantial volumes of natural gas, particularly to operate their steel plants and power generation facilities. Ternium Brasil purchases natural gas at market prices from Companhia Distribuidora de Gás do Rio de Janeiro, or CEG. Ternium Brasil has a natural gas transportation and distribution agreement with CEG that is automatically renewed every year. We consume approximately 0.3 million btu of purchased natural gas to produce one ton of crude steel in Brazil.
Ternium Argentina purchases natural gas at market prices mainly from Tecpetrol, in which San Faustin holds a controlling interest, Pluspetrol S.A., and natural gas traders, including MetroEnergía S.A., Natural Energy S.A., Camuzzi Energía S.A., Gas Patagonia S.A. and Gas Meridional S.R.L. For its San Nicolás facility, Ternium Argentina has a long-term natural gas transportation agreement with Transportadora de Gas del Norte S.A., or TGN, and a renewable one-year natural gas distribution agreement with Litoral Gas S.A., or Litoral Gas. TGN and Litoral Gas are companies in which San Faustin holds significant but non-controlling interests. For its other facilities, Ternium Argentina’s natural gas transportation and distribution needs are covered by the corresponding regional distributors Camuzzi Gas Pampeana S.A., Metrogas S.A. and Naturgy BAN S.A. We consume approximately 4.5 million btu of purchased natural gas to produce one ton of crude steel in Argentina.

Other inputs. Ternium Brasil and Ternium Argentina have on-site oxygen, nitrogen and argon separation plants in order to extract these gases for use in the steelmaking process. Ternium Brasil’s separation plants are managed by a consortium formed by Air Liquide Brasil Ltda., AirSteel Ltda., White Martins Gases Industriais Ltda., White Martins Steel Ltda. and ThyssenKrupp MinEnergy GmbH under a long-term contract for the supply of air, oxygen, nitrogen and argon. Ternium Argentina’s separation plants are managed by Air Liquide Argentina S.A. under a long-term contract for the supply of oxygen, nitrogen and argon.
Colombia
In Colombia, Ternium’s manufacturing of finished steel products relies on three sources: (a) the production of steel in its steelmaking facilities, which are based on the electric arc furnace technology; (b) the purchase of steel billets to be processed in its steel bar and coil mill; and (c) the purchase of steel products, both from our overseas subsidiaries and from third parties. The electric arc furnace technology melts steel scrap to produce steel billets, which are then rolled into various long products. The production process requires extensive use of electricity. Steel products are the largest component of production costs; scrap and electricity costs are also significant.
Semi-finished and finished steel products. The operations in Colombia include non-integrated facilities that process steel supplied by Ternium’s overseas subsidiaries and semi-finished and finished steel purchased from third-party suppliers procured in the domestic and international markets. We purchased from third parties approximately 516,500 tons of semi-finished and finished steel products in 2024, 263,900 tons in 2023 and 155,700 tons in 2022.
Steel scrap. Scrap is the main raw material for producing steel in our steelmaking facilities in Colombia. Ternium sources 100% of its steel scrap needs from the local scrap market. We consume approximately 1.1 tons of scrap to produce one ton of crude steel in Colombia.
Electricity. Manizales is our main electricity consuming unit in Colombia, mainly due to its electric arc furnace-based steel production operations. Manizales purchases electricity from Isagen S.A. E.S.P., a Colombian power company, under a supply contract expiring in December 2028. The electricity price is based on a fixed rate adjusted by the wholesale price index. We consume approximately 0.5 MWH of electricity to produce one ton of crude steel in Colombia.

Research and Development; Product Development
Our research and development efforts are dedicated to expanding our portfolio of advanced steel products, collaborating with customers to design and develop manufactured components incorporating steel and exploring, as well as testing, innovative technologies aimed at decarbonizing our operations.

Our research and development activities, along with our capital expenditures program, are designed to achieve steel products with increasingly complex functional properties and lower carbon footprint. We have shortened the development cycle for new products to promptly make use of the advanced technologies integrated into our facilities. We have also leveraged our research and development capabilities to deliver solutions to our customers for their day-to-day operations.

Ternium Lab, our research and development center in Mexico, features physical modeling, industrial process simulation, robotic testing, full-scale welding processes and advanced characterization. In addition, Usiminas’ research and development center carries out product development, steel product performance testing, applied engineering support and customer technical assistance. We also operate other research facilities with laboratories in Brazil and Argentina, where we carry out product performance tests and production process simulations.

Ternium Lab’s facilities are accredited to certify steel products according to the ISO 17025 international standard and industrial customer specifications, providing reliable services to Ternium’s customers and shortening the product development cycle to accelerate market introduction. Since its inauguration, Ternium Lab has approved over 100 steel products tailored for industrial applications, facilitating the seamless integration of the hot-rolling mill at the Pesquería Industrial Center into Ternium’s product processing workflow.

Ternium Lab has close interactions with many of our automotive customers’ development centers. Vehicle designers have access to our steel products’ performance parameters through their design software, including weldability, deformation and energy absorption capabilities. In addition, we developed a battery pack for electric vehicles, which we have shared with selected customers.

In 2024, we developed a component design laboratory, featuring the digital simulation of stamping and welding tests. In addition, we incorporated a new state-of-the-art continuous galvanizing simulator into Ternium Lab, which allows us to evaluate new coatings performance and simulate the integral galvanizing process. With this simulator, we plan to enhance the development of advanced hot-rolled galvanized steel products, to be processed in the new galvanizing line being built at the Pesquería Industrial Center. The line is expected to produce high-strength, high-gauge products for the automotive and renewable energy markets.

72


Usiminas’ customer technical support is focused on advising and assisting users on issues concerning the final application of the product engineering, including the stamping process, welding, fatigue, corrosion resistance, wear resistance, zinc and post treatment coatings and structural integrity.

Ternium is working with its affiliated companies Tenova and Tecpetrol to develop new process technologies aimed at reducing the carbon footprint of steel products. To this end, we are building pilot equipment and have enhanced our computing capabilities to simulate and study fuel injection mechanisms in a blast furnace and in a direct reduction unit, aimed at injecting renewable fuels to substitute natural gas. These fuels are obtained from raw materials or energy sources that are restored or regenerated at a pace similar to their consumption rate. In addition, we are developing processes aimed at improving the performance of steelmaking raw materials.

Ternium’s in-house research activities are enhanced by our participation in a global network of industry consortia, universities and research centers. As part of the Steel E-Motive initiative, in 2024 we engaged in activities aimed at fostering the adoption and integration of parts and design concepts developed under this initiative and to position the steel industry as the most efficient in the construction of autonomous cars. Sponsored by WorldAutoSteel, this project focused on the design of cost-effective, safe and sustainable connected autonomous electric vehicles using advanced engineering and high-strength steel technologies.

We continue to assist manufacturers of heavy transport equipment in designing high-performance components and developing their associated manufacturing processes, leveraging on improved capabilities of new high-strength steel products. In 2024, we initiated the patenting procedure for Ternium’s high abrasion-resistant solution in Mexico.

Furthermore, in 2024, we organized a contest on vehicle interior design, aligned with the Steel E-Motive concept at the Instituto Tecnológico de Monterrey. We also conducted a chassis design competition for heavy vehicles, emphasizing adaptability enhancement for both electric and internal combustion engines while minimizing component variations.

Regulations
Environmental, Social and Governance Regulations
We are subject to a wide range of local, provincial and national laws, regulations, permit requirements and decrees relating to environmental, social and governance matters, including laws and regulations relating to climate-change mitigation, use of resources, hazardous materials and radioactive materials, air emissions, water discharges and waste management; legislation on human rights and modern slavery; human capital, including equal opportunity, gender and disabilities equality, working conditions, work-life balance, and labor market access; and applicable rules on internal control and risk management, anti-corruption, business partner relationship management and other governance issues. For more information on the company’s governance practices and applicable regulations, see Item 6 “Directors, Senior Management and Employees” and Item 16G. “Corporate Governance".
These regulations have been evolving over the past years and are expected to continue to evolve in the future, with related laws and regulations becoming increasingly complex and expensive to implement in recent years.
In response to an increasing investor focus and reliance on climate and ESG-related disclosure and investment, the SEC announced in March 2021 the creation of a Climate and ESG Task Force to identify ESG-related misconduct and potential violations, and in March 2022, the SEC released a proposal to amend its disclosure rules on climate change matters. In March 2024, the SEC adopted the final rules on climate-related disclosures, which would have required registrants, including Ternium, to significantly expand the climate-related disclosures in their periodic reports, including information about climate-related risks that are reasonably likely to have a material impact on their business, results of operations, or financial condition, and certain climate-related financial statement metrics in a note to their audited financial statements. The implementation of this rule had been voluntarily stayed by the SEC in April 2024, pending judicial review due to legal challenges and, on March 27, 2025, the SEC withdrew its legal defense of the climate change rule.
The Paris Agreement, adopted at the 2015 United Nations Climate Conference, sets out the global framework to limit the rising temperature of the planet and to strengthen the countries’ ability to deal with the effects of climate change. In order to achieve carbon neutrality by the year 2050, the European Commission has laid out several action plans, such as the EU climate adaptation strategy, sustainable finance policies and the raw materials alliance. The EU taxonomy classification system, which establishes a list of environmentally sustainable economic activities, is designed to help the EU scale up sustainable investment and implement the European Green Deal.
73


In addition, as part of the European Green Deal, the EU adopted the Corporate Sustainability Reporting Directive (CSRD), which requires European large companies and listed issuers to disclose information on their risks and opportunities arising from social and environmental issues, and on the impacts of their activities on people and the environment, and the Corporate Sustainability Due Diligence Directive (CSDDD), which mandates that companies operating within the European Union identify, prevent, mitigate, and account for adverse human rights and environmental impacts in their operations and supply chains. Recently, in response to the need to strengthen the competitiveness of the EU economy, the European Commission has recently proposed to simplify sustainability reporting rules and boost investments through a package of proposed amendments to the Corporate Sustainability Reporting Directive (CSRD), the EU Taxonomy, the Corporate Sustainability Due Diligence Directive (CSDDD), the EU’s Carbon Border Adjustment Mechanism (CBAM) and current investment programs. If the proposed amendments are approved, Ternium will be required to comply with the Corporate Sustainability Reporting Directive (CSRD) and the EU Taxonomy, with respect to the Ternium S.A.’s 2027 annual report, and with the Corporate Sustainability Due Diligence Directive (CSDDD) starting on July 2028.
Laws and regulations protecting the environment have become increasingly complex and more stringent in recent years, leading to higher compliance costs. Environmental requirements vary from one jurisdiction to another adding complexity to the operations of companies with activity in multiple countries, such as Ternium. In addition to laws, regulations and policies aimed at enhancing transparency and promoting sustainability-related practices, there has been recently an increase in regulatory activity against climate and diversity-related initiatives in certain countries, which has led and may continue to lead to new laws, regulations and policies seeking to limit, discourage or prohibit such initiatives.
The ultimate impact of complying with ESG regulations, in particular with applicable environmental regulation, is not always clearly known or determinable because certain laws and regulations have been evolving in the past years or are under constant review by competent authorities. Failure to comply with any legislation, regulation or policy, including as a result of good faith interpretations that may differ from those taken by enforcement authorities in relevant jurisdictions, could lead to substantial fines, regulatory sanctions, reputational damage and operational changes. In addition, increasing public awareness on environmental matters put pressure on governmental authorities to adopt measures or take initiatives that show concern for such matters, including by inspecting, monitoring or sanctioning local industries. The expenditures required to comply with environmental laws and regulations, including site or other remediation costs, or costs incurred from potential environmental liabilities, could have a material adverse effect on our financial condition and profitability. While we incur and will continue to incur expenditures to comply with applicable laws and regulations, there always remains a risk that environmental incidents or accidents may occur that may negatively affect our reputation or our operations.
For more information on the impact of climate change legislations and increasing regulatory requirements, see Item 3.D. “Key Information – Risk Factors - Certain Regulatory Risks and Litigation Risks – The cost of complying with environmental regulations, potential product and environmental liabilities in a context of increasing environmental awareness, as well as governmental measures driven by social pressure to address environmental concerns, may affect Ternium’s steel production or processing operations, or may increase Ternium’s operating costs, negatively impacting Ternium’s business, financial condition, results of operations and prospects;” and Item 3.D. “Key Information – Risk Factors - Certain Regulatory Risks and Litigation Risks – Climate change legislation and increasing climate regulatory requirements aimed at transitioning to a lower-carbon economy, together with increasing stakeholder expectations for reduced carbon emissions, could result in unexpected capital expenditures and costs, negatively affect Ternium’s competitiveness, reducing its market share and results of operations, and hampering its ability to access adequate financial resources.”
Below is a summary of relevant environmental legislation applicable to Ternium.
Mexico:
Mexican environmental laws establish the “polluter pays” principle, pursuant to which the individual that causes an environmental breach is responsible for restoring the environment to its pre-pollution condition and face economic and, in some cases, criminal liabilities. Mexican regulations also establish an annual report scheme of GHG emissions.
In addition, Mexican regulations provide for carbon dioxide emission taxes through taxes on fuels, with rates reviewed annually, depending on their efficiency in terms of carbon dioxide emission per unit of energy obtained. The carbon dioxide emission tax for natural gas is currently zero. In 2019, Mexico also started a pilot program for the adoption of an Emissions Trading System aimed at reducing GHG emissions, by settling a cap on emissions and allowing for the trade of emission certificates. Although the operational phase was expected to commence during the third quarter of 2023, as of the date of this annual report the applicable rules are not yet known.
74


Ternium Mexico is a large consumer of natural gas. For further information see “—Raw Materials, Slabs, Energy and Other Inputs.”
Brazil:
The company’s activities are subject to a wide range of local, provincial and national laws, regulations, permit requirements and decrees relating to environmental, social and governance matters, including laws and regulations relating to climate-change mitigation, use of resources, hazardous materials and radioactive materials, and air emissions, water discharges and waste management, and legislation on human rights and modern slavery. Laws and regulations protecting the environment have become increasingly complex and more stringent and expensive to implement in recent years. Compliance with environmental laws and regulations and monitoring regulatory changes are addressed primarily at a regional level.
Brazilian environmental legislation imposes criminal and administrative penalties on natural persons and legal entities that commit environmental crimes or infractions, as well as for the obligation to repair the environmental damage caused. Environmental crimes or infractions could subject the company to penalties that include:
· fines that at the administrative level could reach as high as BRL50 million, depending on the violator’s economic capacity and past record, as well as the severity of the facts and prior history, with the amounts potentially doubled or tripled in the case of repeat offenders;
· suspension of or interference in the activities of the respective enterprise; and
· loss of benefits, such as the suspension of government financing and the inability to qualify for public bidding processes and tax breaks.
In addition, strict liability is applicable to environmental crimes for both natural persons and legal entities. Environmental legislation also provides for disregarding the legal status of a company’s controlling shareholders whenever such status represents an impediment to receiving restitution for environmental damages.
In the civil sphere, environmental damage results in joint and several liability as well as strict liability. This means that the obligation to repair the environmental damage may affect all those directly or indirectly involved, regardless of any proof of who is to blame. As a result, the hiring of third parties to intervene in its operations to perform such services as final disposal of solid waste does not exempt the company from liability for any environmental damage that may occur.
Argentina:
Argentine environmental laws and regulations require the renewal of environmental licenses and emission permits every two or four years, depending on the activity. Although such renewals may take longer than expected and the renewal process may extend beyond the due date of the then current licenses and permits, no shut down orders against the company have ever been issued while the renewal processes are ongoing. In addition, Argentine environmental laws and regulations require mandatory environmental insurance to cover facilities that use hazardous materials.
Argentine legislation provides for mandatory minimum shares of renewable energy in total electricity consumption. For further information see Item 4. “Information on the Company—B. Business Overview—Raw Materials, Slabs, Energy and Other Inputs—Brazil and Argentina—Electricity”.
In addition, Argentine law provides for a carbon dioxide emission tax. Natural gas is excluded from such tax, and metallurgical coal and petrochemical coke are exempted as long as they are used as part of an industrial process, other than for energy generation. Effective since March 2018, the tax on fossil fuels is set to increase 10% every year until 2028, when it is expected to reach an average $10 per ton of carbon dioxide equivalent emitted. For additional information regarding how carbon taxes affect our operations in Argentina, see Item 3. “Key Information—D. Risk Factors—Certain Regulatory Risks And Litigation Risks—Climate change legislation and increasing climate regulatory requirements aimed at transitioning to a lower-carbon economy, together with increasing stakeholder expectations for reduced carbon emissions, could result in unexpected capital expenditures and costs, negatively affect Ternium’s competitiveness, reducing its market share and results of operations, and hampering its ability to access adequate financial resources.”

Mining regulations in Mexico
Because our operations in Mexico include mining, we are also subject to Mexican regulations relating to mining and mining concessions. Under Mexican law, mineral resources belong to the Mexican nation and a concession from the Mexican federal government is required to explore for or exploit mineral reserves. Pursuant to Mexico’s Mining Law, mining concessions may only be granted to Mexican individuals and to legal entities incorporated under Mexican law. Foreign investors may hold up to 100% of the shares of such entities.
A mining concession allows its holder to perform both exploration works (including identifying mineral deposits and quantifying and evaluating economically minable reserves) and exploitation works (including detaching and extracting mineral products from such deposits). Mining concessions are granted for a 50-year period from the date of their recording in the Public Mining Registry; following the expiration of the initial concession term, the concessions are renewable for an additional 50-year term in accordance with, and subject to, the procedures set forth in the Mining Law.
Mining concessions grant several specified rights to the concessionaire, including:
•the right to dispose freely of mineral products obtained as a result of the exploitation of the concession;
•the right to obtain the expropriation of, or an easement with respect to, the land where the exploration or exploitation will be conducted; and
•the use of water in the mine to facilitate extraction.
In addition, a holder of a mining concession is obligated, among other things, to explore or exploit the relevant concession (including the achievement of minimum investment targets), to pay for any relevant mining rights, to comply with all environmental and safety standards, and to provide information to and permit inspections by the Secretariat of Economy. Mining concessions may be terminated if the obligations of the concessionaire are not satisfied.
A company that holds a concession must be registered with the Public Mining Registry. In addition, mining concessions and permits, assignments, transfers and encumbrances must be recorded with the Public Mining Registry to be enforceable. We believe that our material mining concessions are duly registered in the Public Mining Registry.
In April 2023, Mexico approved a significant reform to its mining laws. Among other changes, new mining activities were prohibited in certain areas with superficial bodies of water -which are of federal jurisdiction-, and areas declared as natural reserves by federal or local governments. In addition, governmental authorities are authorized to order the removal of existing tailings deposits under certain location or risk circumstances. The new legislation prohibits the use of national waters for the transportation of certain materials, grants to the Mexican geological service exclusive rights to conduct exploration activities, and requires mandatory bidding processes for new exploration and exploitation concessions, limiting concessions to a 30-year duration with 25-year automatic extension and a further 25-year extension following a prior bidding process. Concessions may be revoked on certain grounds, including for failure to initiate or interrupt operations within a specified timeframe or to file a mine closing plan, and accidents may be punished with increased fines and other penalties. In addition, new permits entailing an increase in water consumption in the regions where Las Encinas and Peña Colorada operate are subject to new water consumption permits based on such new conditions. The reform also regulates royalties and profit sharing with local communities, and mandates consultation processes with native and Afro-Mexican communities. The Supreme Court is reviewing the constitutionality of the new legislation.
For information regarding amendments to the mining law and regulations in Mexico, see Item 3. “Key Information—D. Risk Factors—Risks Relating to Ternium's Mining Activities—Required governmental concessions could be subject to prior consultation with native communities in Mexico or local communities in Brazil, changes or termination, permits and rights of use and occupancy could be difficult to obtain or maintain and taxes or royalties applicable to the mining industry could increase, all of which could adversely affect Ternium’s mining activities and operating costs.”
Mining regulations in Brazil
Our operations are subject to Brazilian regulations relating to mining and mining concessions. Under Brazilian law, mineral resources belong to the Brazilian nation and can only be exploited under a government concession. We are required to obtain authorizations, licenses, permits or approvals from governmental authorities to construct and operate mining facilities.
76


Government agencies are generally responsible for granting mining concessions and monitoring compliance with mining laws and regulations.
The Brazilian National Mining Agency has issued several resolutions regulating companies operating tailings dams in the country. These resolutions provide for the embargo and suspension of tailings dams and mining complexes in certain situations. They also provide for fines of up to BRL1 billion, calculated on the basis of the mining company's total revenues and research budget. Several laws and regulations issued by the Brazilian Federal Government and the State of Minas Gerais provide for the prohibition and timely decommissioning of upstream tailings dams. Mineração Usiminas has completed the decommissioning of its upstream tailings dams and has implemented tailings filtration and storage methods that do not rely on tailings dams to continue operating its mines and plants. Its last tailings dam, constructed as a downstream method, is in the process of de-characterisation. There are no tailings dams in operation. For further information see Item 4. “Information on the Company - B. Business Overview - Mining Production Facilities in Brazil.”
Mineração Usiminas also complies with other laws and regulations related to mining activities, including those for the protection of caves.


Trade regulations
Intense global competition in the steel industry leads many countries, from time to time, to increase duties or impose restrictions on steel product imports to protect their domestic industries from trades that are not made under market conditions or that are otherwise unfair. Such measures protect domestic industries from increased imports sold at dumped or subsidized prices. Mexico, Colombia and the United States, among other countries, have several trade remedy measures in place. In addition to antidumping and countervailing measures, U.S. authorities have imposed tariffs on steel imports under Section 232 of the Trade Expansion Act of 1962 and tariffs through the International Emergency Economic Powers Act. For additional information on the Trump’s administration trade actions, see “—Regulations—Trade Regulations—United States.”

Bilateral or regional free trade agreements have liberalized trade among some countries, providing for reduced or zero tariffs for many goods, including steel products. The entry into force of various free trade agreements and certain countries’ imposition of trade remedy measures can and have both benefited and adversely affected Ternium’s home markets and export sales of steel products, as described below. For further information, see also Item 3. “Key Information—D. Risk Factors—Certain Regulatory Risks and Litigation Risks—International trade actions or regulations and trade-related legal proceedings could adversely affect Ternium’s sales, revenues and overall business.” Relevant free trade agreements and trade remedy measures, by country, are described below:

Mexico
Imports of steel products in Mexico:
The Mexican government has imposed certain antidumping measures on imports of steel products that are similar to the ones produced by Ternium Mexico. The following is a description of measures currently in effect and ongoing investigations:
•Hot-rolled products: On March 28, 2000, the Mexican government imposed antidumping duties on the Russian Federation and Ukraine of 30.31% and 46.66%, respectively, on hot-rolled products. The measure has been extended four times for five years each, on March 17, 2006; on September 8, 2011 (modifying the duties to 21% and 25% for Russia and Ukraine respectively); on January 28, 2016; and on March 23, 2021. On July 19, 2013, the Mexican government initiated an anti-circumvention investigation on imports of boron-alloyed hot-rolled products from Russia. On March 21, 2014, Mexico’s Secretariat of Economy published the final determination on the investigation, by which boron-alloyed hot-rolled products from Russia are now subject to a 21% antidumping duty. Furthermore, on December 22, 2015, the Mexican government published the final antidumping determination imposing definitive and specific antidumping duties on China ($354.92 per ton, except for imports from Tangshan Iron and Steel Group Company Limited, which were fixed in $335.60 per ton), Germany ($166.01 per ton, except for imports from ArcelorMittal Bremen GmbH, which were fixed in $137 per ton) and France ($75.59 per ton, except for imports from ArcelorMittal Mediterranée S.A.S., which were fixed in $67.54 per ton), on hot-rolled products. The measure was extended for five years on April 19, 2022. On March 3, 2025, Mexico initiated an antidumping investigation on imports of hot-rolled products from Vietnam and China, excluding imports that are already subject to an antidumping duty.
77



•Plate in coils: Since June 1996, an antidumping duty of 29.3% has been in place on imports from Russia. The measure has been extended four times, in June 2003, June 2007, November 2012 and May 2017. On July 5, 2013, the Mexican government initiated an anti-circumvention investigation on imports of boron-alloyed plate in coil imports from Russia. On February 19, 2014, Mexico’s Secretariat of Economy published the final determination on the investigation by which boron-alloyed plate in coil imports are now subject to a 29.3% antidumping duty. On November 24, 2022, the measure was extended for 5 more years, until June 2026. On the same date, the Mexican government initiated a change of circumstances review of the measure in connection with the Russia-Ukraine war. A preliminary determination was issued on September 21, 2023, with an antidumping duty of 12.35%, but the final determination, issued on April 15, 2024, reversed the preliminary determination and confirmed the original duty of 29.3%.

•Cold-rolled products: In June 1999, Mexico imposed antidumping duties on cold-rolled steel sheets from the Russian Federation and Kazakhstan of 15% and 22%, respectively. The measure has been extended four times, in December 2005, December 2010, July 2015, and August 2020. The measure is currently under sunset review initiated on June 28, 2024. In addition, on October 1, 2012, the Mexican government initiated an antidumping investigation on cold-rolled steel imports from South Korea. On December 26, 2013, Mexico’s Secretariat of Economy published a suspension agreement under which Korean exporters, Posco and Hyundai Hysco Company Limited, or Hyundai, voluntarily undertook to limit their cold-rolled products exports to the Mexican market. On May 25, 2016, the Mexican authorities initiated a change of circumstances review of this suspension agreement, and on June 13, 2017, the Secretariat of Economy issued a final determination increasing Posco’s and Hyundai’s quotas for 2017 and 2018. On August 23, 2018, the Mexican government initiated a sunset review of the agreement and issued a final affirmative determination on November 1, 2019. On May 14, 2019, Mexico initiated a second change of circumstances review of the suspension agreement for Posco and on November 5, 2020, a final determination was issued increasing Posco's quota for the years 2019 to 2023. On December 22, 2023, a sunset and a change of circumstances review of the measure were initiated. On June 14, 2024, the Mexican authorities issued a preliminary determination continuing the investigation without amending the measures; the final determination has not been issued as of the date of this annual report. In addition, on June 19, 2015, Mexico imposed antidumping duties on cold-rolled steel products from China between 65.99% and 103.41%, with rates depending on the Chinese exporting company. The measure was extended for five years in August 2022. In December 2015, Mexico initiated a circumvention inquiry against cold rolled steel products with boron added from China. On July 11, 2016, the Mexican government issued a final determination confirming China’s circumvention practice and thus, extending the antidumping duties. On August 16, 2021, under the latest sunset review, this measure was extended until June 2025. In addition, on July 28, 2022, the Mexican government initiated an antidumping investigation on imports of cold-rolled steel from Vietnam and on December 28, 2023, it imposed final antidumping duties on margins from 11.64% to 79.24%.

•Coated flat products: On December 17, 2015, the Mexican government initiated an antidumping investigation on coated flat products from China and Taiwan. On July 29, 2016, Mexico issued a preliminary determination imposing provisional antidumping duties on Chinese exports of between $192 and $438 per ton, and of $563 per ton on Taiwanese products. On June 5, 2017, Mexico issued a final determination imposing antidumping duties on Chinese exports of between 22.22% and 76.33%, and of between 22.26% and 52.57% on Taiwanese products. On November 21, 2017, Mexico amended its final determination imposing antidumping duties applicable to products sold by Chinese companies, one of which was imposed duties for $187 per ton, while others face duties ranging between 22.26% and 76.33% of the products’ price. On September 13, 2023, these measures were renewed until June 2027. In addition, on August 30, 2021, Mexico initiated an antidumping investigation on coated flat products imports from Vietnam, and on February 24, 2023, Mexico issued a final determination imposing antidumping duties applicable to products sold by Vietnamese companies, of up to 10.84%. On September 14, 2023, Mexico imposed an antidumping duty of 2.06% to Maruichi Sun Steel, the only Vietnamese company not previously covered by the order.

•Reinforcing bars: Since 1995, imports of reinforcing bars from Brazil are subject to an antidumping duty of 57.69%. Subsequent sunset reviews determined the continuation of the antidumping duty for additional five-year periods. On December 23, 2021, under the latest sunset review, this measure was extended until August 2025.

•Wire rod: Since September 2000, imports of wire rod from Ukraine are subject to an antidumping duty. The initial antidumping margin was 30.52%. In June 2006, the first sunset review resolution determined the continuation of the antidumping duty for five more years. On September 7, 2010, a second sunset review was initiated, and on March 7, 2012, the Mexican government increased the antidumping duty to 41% until September 2015. The Mexican government initiated the third sunset review on September 4, 2015, and extended the measures for an additional five-year period on September 2, 2016. On Dec. 10, 2021, under the latest sunset review, this measure was extended until September 2025. In addition, on September 2, 2015, the Mexican government initiated an antidumping investigation on wire rod from China. On July 28, 2016, the Mexican government imposed a specific antidumping duty of US$0.49 per kilogram for five years, extended for an additional five-year period on January 19, 2023.
78



•Welded Tubes: On December 7, 2016, the Mexican government initiated an antidumping investigation on welded tubes of circular, square or rectangular cross section from China. On March 8, 2018, Mexico imposed final antidumping duties on Chinese exports of between $356 and $618 per ton. The Mexican Government initiated the sunset review together with a change of circumstances review of the measure on March 7, 2023, and on April 30, 2024, decided to extend the measure without amendments until March 2028.
On October 7, 2015, the Mexican Government issued a decree imposing a temporary 15% import tariff on steel products other than semi-finished products, including plate, hot-rolled, cold-rolled, coated, tubular, structural and wire rod, applicable to imports from countries with whom Mexico had no trade agreement in place. Per the amendment to the tariff schedule published on November 18, 2022, the import tariff of most products was to be reduced to 10% from June 1, 2023 and would be further reduced to 5% from September 22, 2023 (and lifted on October 1, 2024) with the exception of certain products that have different tariff reduction schedules (such as two-size zinc plated steel sheets and some seamless pipe products, towers and lattice masts). However, on August 15, 2023, Mexico amended the rule, increasing the scope of the measure and the tariffs to 25% for the majority of steel products until July 31, 2025. In addition, on April 23, 2024, Mexico increased import tariffs to a range of between 25% and 50% on several steel products including all steel family products except semi-finished steel. Finally, starting on April 16, 2024, Mexico increased information requirements on steel import licenses to include information on mill and quality certificates and country where the product was melted and poured.
Exports of steel products from Mexico:
U.S. authorities have imposed a number of antidumping and countervailing measures on steel import from Mexico, thereby restricting Ternium’s exports to the U.S. The following is a description of measures currently in effect and ongoing investigations:
•Corrosion-resistant flat products: On September 25, 2024 the U.S. Department of Commerce initiated antidumping and countervailing investigations on corrosion-resistant flat products (“CORE”) from 10 countries including Mexico. For further information, see “—Regulations—Trade Regulations—United States.”
•Carbon and alloy steel wire rod: Ternium Mexico's wire rod exports are subject to an antidumping duty of 4.64% pursuant to the latest administrative review on the antidumping duty order on carbon and certain alloy steel wire rod. On August 27, 2020, as a result of the most recent sunset review, such duty was extended for five more years.
•Pipe and tube: During 2007, U.S. authorities initiated an antidumping investigation of light-walled rectangular pipe and tube, or LWRPT, from various countries, including Mexico. On June 13, 2008, the authorities made a final determination of sales at less than fair value in the investigation of LWRPT from Mexico and, consequently, imposed antidumping duties. On February 18, 2011, the authorities published the final results of the first administrative review by which Mexican LWRPT exports were subject to an antidumping duty of 6.13% until May 23, 2014, when U.S. authorities made a final affirmative sunset review of 2.40% for Maquilacero and 3.76% for certain other companies subject to the review, including Ternium Mexico. On March 12, 2018, U.S. authorities published the final results of the 2015-2016 administrative review, which did not impose any antidumping duties on Prolamsa and Aceros Cuatro Caminos S.A. de C.V., but imposed an antidumping duty of 3.76% on other exporters. On April 22, 2019, the U.S. authorities imposed a duty range of between 8.32% and 17.65% for certain Mexican producers or exporters as a result of the 2016-2017 administrative review. On August 4, 2020, as a result of the most recent sunset review, such duty was extended for five more years. As a result of the 2022-2023 review, Ternium Mexico’s current preliminary margin is 13.73%, with final results expected by April 2025.

On August 10, 2015, U.S. authorities initiated an antidumping investigation on imports of heavy-walled rectangular pipe and tube, or HWRPT, from Korea, Turkey and Mexico. On September 13, 2016, the authorities issued an antidumping duty order on imports of HWRPT, imposing an antidumping duty range of between 2.34% and 3.82% for Korea, 17.83% and 35.66% for Turkey, and in the case of Mexico 3.83% for Maquilacero, 5.21% for Productos y Laminados de Monterrey and 4.91% for Ternium Mexico and others. On July 10, 2019, the U.S. authorities issued the final results of the 2016-2017 administrative review imposing duties of 1.43%, 8.09% and 6.13% on Maquilacero, Prolamsa and other exporters including Ternium, respectively. On July 13, 2020, U.S. authorities issued the final results of the 2017-2018 administrative review imposing duties of 4.89%, 7.47% and 4.91% on Maquilacero, Prolamsa and other exporters, respectively. Ternium Mexico’s current margin per the 2018-2019 administrative review is 2.51%.

•Welded pipes: Since 1992, pursuant to an antidumping duty order on circular welded non-alloy steel pipe -or standard pipe- from various countries, including Mexico, standard pipes manufactured by Hylsamex and Grupo Imsa were subject to antidumping duties. In 2007, such measures were extended for five more years. In August 2009, U.S. authorities published the final results of a changed circumstances review, concluding that Ternium Mexico is the successor-in-interest to Hylsamex for purposes of determining antidumping duty liability. In accordance with the latest administrative review, the applicable duty for Ternium Mexico is 24.17%. The measure has since been extended two more times, in 2012 and February 2018. The U.S. Government initiated the sunset review of the measure on January 3, 2023, and extended it for five more years on January 11, 2024.
•Reinforced bars: On November 6, 2014, U.S. authorities made a final determination on reinforced bar imports from Mexico, imposing antidumping duties between 20.58% and 66.70%. As a result of the 2016-2017 administrative review, the U.S. Government imposed a duty of 3.65% on Mexican producers, including Ternium Mexico. As a result of the 2017-2018 administrative review, the U.S. Government imposed duties of 7.12% for Deacero, 1.46% for Grupo Simec and 5.54% for other Mexican producers, including Ternium Mexico. The measure was renewed on October 22, 2020 for five more years.

In addition, U.S. authorities have imposed tariffs, including on imports from Mexico, under Section 232 of the Trade Expansion Act of 1962 and through the IEEPA. Further, the Trump administration announced that the U.S. would implement reciprocal tariffs with trading partners by April 2025. For additional information on the Trump’s administration trade actions, see “—Regulations—Trade Regulations—United States.”
Trade agreements:
Mexico has signed trade agreements with several countries or trade blocs aimed at liberalizing trade between them:
NAFTA was signed among Canada, Mexico and the United States and came into effect on January 1, 1994. NAFTA provided for the progressive elimination over a 10-year period of duties on steel products traded between or among Mexico, the United States and Canada, among other things. As a result, zero tariffs applied to steel products traded within NAFTA countries. However, steel imports in the United States from Mexico and Canada are currently subject to tariffs under Section 232 and, if they do not comply with USMCA preferential rules of origin, subject to tariffs through the IEEPA. For additional information on the Trump’s administration trade actions, see “—Trade Regulations—United States.”
NAFTA was subsequently replaced by the United States-Mexico-Canada Agreement, or USMCA, which became effective in July 2020. The United States, Mexico and Canada agreed to modify the definition of "North American steel" (with such amendment becoming effective in July 2027), for purposes of vehicles being awarded preferential treatment under USMCA, restricting the defined term to steel melted and poured within the three countries.
The USMCA is scheduled for its first joint review on July 1, 2026, allowing the three member countries to assess the agreement and propose revisions. The review signals the beginning of a 10-year countdown to the USMCA’s expiration in 2036, unless the parties agree to extend the agreement. For a discussion of risks relating to changes in the USMCA, see Item 3. “Key Information—D. Risk Factors—Certain Regulatory Risks and Litigation Risks— Changes in existing trade arrangements between Mexico and the U.S. and controversies or disputes between USMCA member countries could adversely impact Ternium’s results of operations and net results.”
The Mexican-European Free Trade Agreement, or MEFTA, became effective on July 1, 2000. MEFTA provided for the phase-out and eventual elimination of Mexican and European duties on all industrial goods, including finished steel products. The European Union eliminated all import duties on Mexican industrial goods, including finished steel products, as of January 1, 2003, while Mexico eliminated all import duties on European industrial goods, including finished steel products, as of January 1, 2007. During April 2018, the European Union and Mexico concluded negotiations to bring the MEFTA up to date. The amended agreement, which has not yet come into force, does not provide for changes in steel trade conditions. Following BREXIT, Mexico and the United Kingdom reached a Trade Continuation Agreement, published on June 1, 2021, effective retroactively from January 1, 2021.

The Economic Partnership Agreement between Japan and Mexico came into force on April 1, 2015. The new agreement provides for a phase-out and eventual elimination of Mexican and Japanese duties on all industrial goods within a ten-year period. Beginning on April 1, 2015, all duties on steel products were eliminated. Until March 31, 2015, an import duty of 3% was applicable to Japanese steel imports.

Mexico and Argentina signed an Economic Complementation Agreement, known as ACE 6 for its initials in Spanish, in November 2003, whereby reciprocal tariff preferences are currently granted. In 2006, Mexico and Argentina modified the ACE 6 Agreement, reducing to zero import duties on imports of certain steel products from the other country.
80


Zero import duties included exports from Mexico to Argentina and vice versa for up to 90,000 tons per year of slabs, 60,000 tons per year of cold rolled coils and 30,000 tons per year of corrosion resistant coils, including hot dip galvanized and pre-painted sheets.
The Comprehensive and Progressive Agreement for Trans-Pacific Partnership, or CPTPP, was signed by Mexico together with Australia, Brunei, Canada, Chile, Japan, Malaysia, New Zealand, Peru, Singapore and Vietnam, becoming effective in December 2018. The agreement is in force for all its members. On July 16, 2023, the United Kingdom officially joined CPTPP. Its accession protocol was ratified and entered into force between the United Kingdom and Australia, Brunei, Chile, Japan, Malaysia, New Zealand, Peru, Singapore and Vietnam on December 15, 2024. Mexico and Canada are expected to ratify the UK’s accession protocol during the first half of 2025.
Mexico has also entered into trade agreements with Colombia, Chile, Bolivia, Nicaragua, Costa Rica, Uruguay and the European Free Trade Association, an intergovernmental organization set up by Liechtenstein, Norway, Iceland and Switzerland, among others.
Brazil
Imports of steel products in Brazil:
The Brazilian government has imposed certain antidumping measures on imports of steel products that are similar to the ones produced by Usiminas. The following is a description of measures currently in effect and ongoing investigations:
•    Plates: In 2019, the Brazilian government renewed an anti-dumping measure, originally applied in 2013, on imports of plates originating in China, South Korea and Ukraine, in the form of specific rates ranging from $52.02/t to $211,56/t, which remained in force until October 2024. The measure is currently under review.

•    Tinplate products: On March 4, 2024, the Brazilian government initiated an anti-dumping investigation into imports of metallic coating steel from China. A provisional measure has been applying since October, 21, 2024.

•    Cold-rolled products: On August 19, 2024, the Brazilian government initiated an anti-dumping investigation into imports of cold-rolled steel from China. On March 12, 2025, the Brazilian government issued a positive preliminary determination without imposing preliminary duties.

•    Coated products: On September 2, 2024, the Brazilian government initiated an anti-dumping investigation into imports of coated steel from China.

•    Pre-painted steel products: On September 19, 2024, the Brazilian government initiated an anti-dumping investigation into imports of pre-painted steel from China and India.

On April 23, 2024, the Brazilian Government established a one-year quota system on steel imports, in effect from June 1, 2024 to May 31, 2025, under which steel imports of certain products exceeding established quotas are subject to a 25% tariff.

Exports of steel products from Brazil:
The following is a description of antidumping and countervailing measures currently in effect and ongoing investigations:
•Corrosion-resistant flat products: On September 25, 2024 the U.S. Department of Commerce initiated antidumping and countervailing investigations on CORE from 10 countries including Brazil. For further information, see “—Regulations—Trade Regulations—United States.”
•Hot-rolled flat products: On December 12, 2023, the European Commission extended for 5 years the application of the September 2019 order that imposed antidumping duties on hot-rolled coils from Brazil, Iran and Russia. The rate applicable to Usiminas is EUR63 per net ton.

In addition, U.S. authorities have imposed tariffs, including on imports from Brazil, under Section 232 of the Trade Expansion Act of 1962. Further, the Trump administration announced that the U.S. would implement reciprocal tariffs with trading partners by April 2025. For additional information on Trump’s administration trade actions, see “—Regulations—Trade Regulations—United States.”
81


Trade agreements:
Brazil has signed free trade agreements with several countries or trade blocs aimed at liberalizing trade between them, including the following:
In early 1991, Brazil entered, together with Argentina, Uruguay and Paraguay, into the Treaty of Asunción, creating the Mercado Común del Sur (Southern Common Market, or "Mercosur"), a common market organization that aimed to bring about the free movement of goods, capital, services and people among its member states. In 2004, the Mercosur members entered into the Protocol of Ouro Preto, creating a customs union among them. On January 1, 2013, Venezuela became a full member of Mercosur but was suspended in December 2016. Over time, Mercosur has eliminated or significantly reduced import duties, tariffs and other trade barriers among member states. Since January 1, 2000, zero tariffs apply to steel products traded among them.
Applicable steel import tariffs to Mercosur member countries from non-member countries currently were between 2% and 14%. In 2021, Mercosur approved a general 10% reduction, applied by Brazilian (range between 1,8% and 12,6%). However, every six months, Mercosur members may exempt from tariffs a limited number of products imported from non-member countries. Uruguay has elected to exempt certain steel products, including cold-rolled sheets and galvanized flat steel products.
In 2004, Mercosur and the Comunidad Andina de Naciones (Andean Community, or "CAN"), currently including Bolivia, Colombia, Ecuador and Peru, signed a free trade agreement aimed at reducing and eventually eliminating tariffs on steel products traded among member countries. Mercosur entered into a trade agreement with Chile in 2005. As a result, all tariffs on steel products traded between Mercosur and Chile have been eliminated. In addition, Mercosur is negotiating a free trade agreement with the European Union. On June 28, 2019, the parties reached an agreement in principle that is not yet effective.
On December 6, 2024, the leaders of the Mercosur and the European Union announced in Montevideo, Uruguay, the conclusion of negotiations on the partnership agreement between the two blocks. The announcement enabled the preparation of the partnership agreement content for its subsequent signature and ratification.
There are trade agreements initiatives with other countries in the early stage, such as South Korea, Vietnam and Indonesia, with little progress.
Argentina
Imports of steel products in Argentina:
In the past, the Argentine government imposed various antidumping measures on imports of certain flat steel products that compete directly with Ternium’s sales in Argentina. After several subsequent revisions of such cases, there are currently no measures in place.
Exports of steel products:
U.S. authorities have imposed tariffs, including on imports from Argentina, under Section 232 of the Trade Expansion Act of 1962. Further, the Trump administration announced that the U.S. would implement reciprocal tariffs with trading partners by April 2025. For additional information on Trump’s administration trade actions, see “—Regulations —Trade Regulations—United States.”
Trade agreements:
Argentina is a member of Mercosur. For further information on this agreement, see “—Regulations—Trade Regulations—Brazil.” In November 2003, Argentina and Mexico signed the ACE 6. For further information, see “—Regulations—Trade Regulations—Mexico.”
Colombia
Imports of steel products to Colombia:
The Colombian government has imposed certain antidumping and safeguard measures on imports of steel products. The following antidumping measures are currently in effect:
•Steel profiles for drywall: On September 1, 2020, the Colombian government initiated a dumping investigation on imports of steel profiles for drywall from China. On December 2, 2020, the preliminary determination was issued without imposition of provisional duties. On October 29, 2021, the Colombian government imposed final antidumping duties of 37.88%, for a three-year period, starting November 3, 2021. On October 30, 2024, the Colombian government initiated a sunset review of the measure.

•Galvanized and galvalume flat sheet and tiles: On January 22, 2025, the Colombian government imposed definitive antidumping duties on imports of Chinese galvanized and galvalume smooth sheet and galvanized and galvalume tile, consisting of an ad valorem tariff of 41.74% on sheets and 94.64% on tiles for five years.
•Wire Rod: On October 18, 2024, the Colombian government adopted a safeguard measure consisting of a tariff of 30% on imports of wire rod from countries with which Colombia does not have trade agreements. The measure is set to expire in October 2026.
•Reinforced bars: On October 3, 2024, the Colombian government adopted a safeguard measure consisting of a tariff of 14.5% on imports of corrugated iron or steel bars for concrete reinforcement from Andean Community member countries exceeding a consolidated quota of 29,529 tons per year. The measure is set to expire in October 2026.
Trade agreements:
Most steel imports to Colombia from countries with whom Colombia does not have a free trade agreement in place are subject to import tariffs of between 5% and 10%.
Colombia has entered into free trade agreements with several countries or trade blocs aimed at liberalizing trade between them.
CAN is a trading bloc, currently including Bolivia, Colombia, Ecuador and Peru, established during 1993 and approved in 1994 for the purpose of promoting trade relations among its members and between CAN and the rest of the world. The treaty formalized a customs union among CAN’s member states. Over time, CAN has eliminated or significantly reduced import duties, tariffs and other trade barriers among member states. In particular, zero tariffs have applied to steel products imported from other member states since January 1, 2000. CAN and Mercosur have signed a free trade agreement. For further information, see “—Regulations—Trade Regulations—Argentina.”
During June 1994, Colombia and Mexico signed a free trade agreement. For further information on this agreement, see “—Regulations—Trade Regulations—Mexico.”
On August 9, 2007, Colombia, El Salvador, Guatemala and Honduras established the Triángulo Norte (North Triangle or “T”), a free trade agreement. Members of the TN signed multilateral agreements related to funds transfers and local and most favored nation statuses, and signed bilateral agreements aimed at reducing trade duties. Colombia’s free trade agreement with Guatemala started on November 12, 2009; with El Salvador on February 1, 2010; and with Honduras on March 27, 2010. Under TN, zero tariffs apply to several steel products imported from other member states.
Colombia’s free trade agreement with the United States became effective in October 2011. Under this agreement, steel import tariffs from Colombia to the United States were eliminated and steel import tariffs from the United States to Colombia decreased gradually from a range of between 5% and 10% in 2011 to 0% in 2021. In particular, wire rods import tariffs were reduced to 0% beginning in 2012, and rebar import tariffs decreased gradually and were eliminated in 2021. On March 8, 2018, the U.S. president imposed a 25% tariff on steel imports, in force since March 23, 2018. See Item 4. “Information on the Company—B. Business Overview—Regulations—Trade Regulations—United States.”
In addition, Colombia has signed free trade agreements with Chile, Canada, the European Union, South Korea, Costa Rica, Israel and the U.K., in effect since May 2009, August 2011, August 2013, July 2016, August 2016, August 2020 and June 2022, respectively. Colombia has also signed free trade agreements with Panama, United Arab Emirates and Singapore, which are not yet effective. Colombia is currently negotiating free trade agreements with Japan and Turkey.
United States
U.S. authorities have imposed a number of measures on steel product imports, including antidumping and countervailing duties, tariffs under Section 232 of the Trade Expansion Act of 1962 and tariffs through the IEEPA. Further, the Trump administration announced that the U.S. would implement reciprocal tariffs with trading partners by April 2025. For additional information on Trump’s administration trade actions, see Item 3. “Key Information—D. Risk Factors—Certain Regulatory Risks and Litigation Risks— Changes in existing trade arrangements between Mexico and the U.S. and controversies or disputes between USMCA member countries could adversely impact Ternium’s results of operations and net results.”

Below is a description of measures currently in effect and ongoing investigations on steel imports in the United States:
Antidumping and countervailing duties on steel imports:
•Hot-rolled products: In July 1999, the U.S. authorities imposed antidumping duties on hot-rolled products from Russia, currently of up to 184.56%. The measure has been extended twice for five years each, in October 2016 and December 2021. During November 2001, the U.S. government imposed antidumping and countervailing duties on certain hot-rolled carbon steel flat products from China, India, Taiwan, Thailand, Russia, Indonesia and Ukraine. Current antidumping duties range between 12.34% and 90.83% for China, 36.53% and 44.40% for India, 47.86% for Indonesia, 20.28% and 29.14% for Taiwan, 4.41% and 20.30% for Thailand and 90.33% for Ukraine, with rates depending on the exporting company. Current countervailing duties range between 336.62% and 360.23% for India and are set at 10.21% for Indonesia and 2.38% for Thailand. These measures were last confirmed on August 27, 2019, and are currently in a sunset review.

In addition, on September 24, 2015, the U.S. government initiated antidumping and countervailing investigations on hot-rolled products from Australia, Brazil, Japan, Korea, the Netherlands, Turkey and the United Kingdom. On October 3, 2016, the government issued antidumping and countervailing duty orders for a five-year period. Antidumping duties were imposed at the following rates: 29.58% for Australia; between 33.14% and 34.28% for Brazil; between 4.99% and 7.51% for Japan; between 4.61% and 9.49% for Korea; 3.73% for the Netherlands; between 4.15% and 6.77% for Turkey; and 33.06% for the United Kingdom. Countervailing duties were imposed on imports as follows: between 29.07% and 30.51% for Brazil; and between 0% and 9.49% for Korea. With the exception of Brazil, the measure was extended for five years on November 25, 2022.

•Cold-rolled products: On July 14, 2016, the U.S. government imposed antidumping duties on cold-rolled steel products, of 265.79% for China and 71.35% for Japan, and countervailing duties of 256.44% for China. On September 20, 2016, the U.S. government imposed countervailing duties on cold-rolled steel products of between 11.09% and 11.31% from Brazil, 10% from India and between 3.89% and 59.72% from Korea. In addition, on September 20, 2016, the U.S. government imposed antidumping duties on cold-rolled products of between 19.58% and 35.43% from Brazil, 6.78% from India, 7.60% from Korea, and between 5.40% and 25.17% from the United Kingdom. Following affirmative circumvention determinations on imports from Vietnam, the U.S. government imposed the same measures imposed on Chinese imports, and in December 2019 the same measures imposed on Korean imports. With the exception of Brazil, these measures have been extended for five years on August 9, 2022.

•Corrosion-resistant flat products: On July 25, 2016, the U.S. government imposed countervailing duties on corrosion-resistant flat products of 39.05% to 241.07% on imports from China, of 8% to 29.49% on imports from India, of a de minimis to 38.51% on imports from Italy, and of a de minimis to 1.19% on imports from Korea. In addition, on July 25, 2016, the U.S. government imposed antidumping duties on corrosion-resistant flat products of 209.97% from China, between 3.05% and 4.43% from India, 12.63% and 92.12% from Italy, 8.75% and 47.80% from Korea, and 10.34% from Taiwan. These measures were subject to many circumvention inquiries. Currently, imports of corrosion-resistant flat products from Costa Rica, Malaysia, Vietnam and the United Arab Emirates from Chinese hot-rolled coils and/or cold-rolled coils are subject to antidumping and countervailing duties; and imports of corrosion-resistant flat products from Vietnam with Korean and Taiwanese hot-rolled coils and/or cold-rolled coils are subject to antidumping and countervailing duties. These measures have been extended for five years on August 3, 2022.

On September 25, 2024, the U.S. government initiated antidumping investigations on CORE from Australia, Brazil, Canada, Mexico, Netherlands, South Africa, Taiwan, Turkey, United Arab Emirates, and Vietnam and simultaneous countervailing investigations on CORE from Brazil, Mexico, Canada and Vietnam. Preliminary countervailing rate determinations were a de minimis 0.33% for Usiminas and 1.72% for other Brazilian exporters; 0% for Galvasid and 1.56% for other Mexican exporters, including Ternium Mexico; between 1.21% and 41.40% for Canadian exporters; and between 0% and 140.05% for Vietnamese exporters.

•Wire rod: On October 29, 2002, the U.S. government imposed antidumping duties to wire rod imports from Brazil (from 74.35% to 94.73%), Indonesia (4.05%), Moldova (369.10%) and Trinidad and Tobago (11.40%), and countervailing duties to Brazilian wire rod imports of between 2.31% and 6.74%. These measures were renewed for five years on August 27, 2020. On January 8, 2015, the U.S. government imposed antidumping duties (between 106.19% and 110.25%) and countervailing duties (between 178.46% and 193.31%) on wire rod from China, with rates depending on the exporting company. These measures were renewed on June 26, 2020. On January 24, 2018, the U.S. government imposed antidumping duties on wire rod from Russia (between 436.80% and 756.93%), Belarus (280.02%) and the United Arab Emirates (84.10%). On March 14, 2018, the U.S. government imposed antidumping duties on wire rod from South Africa (between 135.46% and 142.26%) and Ukraine (between 34.98% and 44.03%). On March 19, 2018, the U.S. Department of Commerce published its final antidumping and countervailing determinations on imports of wire rod from Italy (antidumping duties of between 12.41% and 18.89% and countervailing duties of between 4.16% and 44.18%), South Korea (antidumping duties of 41.10%), Spain (antidumping duties of between 11.08% and 32.64%), Turkey (antidumping duties of between 4.74% and 7.94% and countervailing duties of between 3.81% and 3.86%) and the United Kingdom (antidumping duties of 147.63%). Following a sunset review, in August 2023 these measures were extended for five more years.

•Tin mill products: On January 24, 2023, the U.S. government initiated a countervailing investigation on imports of tin mill products from China, and an antidumping investigation on imports of tin mill products from Canada, China, Germany, Netherlands, South Korea, Taiwan, Turkey and the United Kingdom. The investigation was terminated and no measure has been applied.

U.S. authorities have imposed a number of measures on steel product imports from Mexico, including carbon and alloy steel wire rod, pipe and tube, and welded pipes. For further information, see “—Regulations—Trade Regulations—Mexico.”
Section 232 tariffs on steel imports:
In April 2017, the U.S. government initiated an investigation under Section 232 of the U.S. Trade Expansion Act. The investigation analyzed the effects of imports of steel products on national security. Based on the result of such investigation and on the resulting Commerce Secretary recommendations, on March 8, 2018, the U.S. president imposed a 25% tariff on steel imports, which entered into force on March 23, 2018, followed by negotiated country-specific exemptions and quota arrangements. Australia, Canada and Mexico were exempted from the tariff (though subject to a continuous monitoring system of their trade flows). Argentina, Brazil and South Korea were also exempted from the measure, subject to quota system agreements covering steel imports from those countries. In 2022, the United States shifted the 25% tariff applicable to the European Union to a Tariff Rate Quota (TRQ) system for steel products melted and poured in this region, and Japan and the United Kingdom entered into similar systems. However, on February 10, 2025, the Trump administration announced, through a presidential proclamation, the reinstatement of the 25% tariff on all steel imports. As a result, all previously exempted or quota-managed countries became subject to the full 25% tariff on their steel exports to the United States.
IEEPA tariffs on imports from Mexico, Canada and China:
On February 1, 2025, the U.S. government announced the imposition, through the IEEPA, of tariffs applicable to all products imported from Mexico, Canada and China. As of the date of this annual report, Mexican and Canadian products that comply with USMCA preferential rules of origin, are exempt from this tariff.
Presidential proclamation on imports of automobiles and automobile parts:
On March 26, 2025, the U.S. government announced a 25% tariff under Section 232 on all imported automobiles produced outside the U.S., effective from April 3, 2025. This tariff will also apply to key auto parts such as engines, transmissions, powertrain parts and electrical components starting on May 3, 2025. However, vehicles and parts that comply with the USMCA will only be subject to this tariff on their non-U.S. specific content, and, in the case of auto parts, only when the government establishes a process to exempt U.S. content from tariffs.
Insurance
Our subsidiaries carry insurance policies covering accidental loss or physical damage to its property and equipment (including machinery breakdown and business interruption arising from an insured event), general liability (including third party, employer, product, sudden and accidental pollution and port liability in the ports operated by Ternium) and other insurance, including marine cargo, construction all risk, life and workers’ compensation and automobile insurance. These insurance policies have coverage, limits and conditions, that we believe are customary in the steel products industry and in line with legal and domestic market requirements. Nevertheless, the limits, deductibles and/or self-insured retentions of these insurance policies may not be sufficient to recover all losses suffered from such events. In addition, some particular events may not be covered under these insurance policies.
Disclosure Pursuant to Section 13(r) of the Exchange Act
The Iran Threat Reduction and Syria Human Rights Act of 2012 added a new paragraph (r) in Section 13 of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”), which requires a reporting issuer to provide disclosure if the issuer or any of its affiliates knowingly engaged in certain enumerated activities relating to Iran, including activities involving the Government of Iran.
85


Ternium did not engage in any Iran related activity during the year ended December 31, 2024. However, Ternium S.A. is providing the following disclosure pursuant to Section 13(r) of the Exchange Act with respect to Iran related activity reported by its affiliates.

Tenaris
Tenaris is also controlled by San Faustin and, accordingly, it is deemed an “affiliate” of Ternium S.A., as such term is defined in Exchange Act Rule 12b-2. In response to our inquiry, Tenaris provided the disclosure included below.
In July 2015, the Islamic Republic of Iran entered into the Joint Comprehensive Plan of Action (“JCPOA”) with China, France, Germany, Russia, the United Kingdom and the United States, which resulted in the partial lifting in January 2016 of certain sanctions and restrictions against Iran, including most U.S. secondary sanctions against such country. On May 8, 2018, the United States announced that it would cease participation in the JCPOA and would begin re-imposing nuclear-related sanctions against Iran after a wind-down period. Following the U.S. withdrawal from the JCPOA, the European Union updated Council Regulation (EC) No. 2271/96 of 22 November 1996 (the “EU Blocking Statute”), to expand its scope to cover the re-imposed U.S. nuclear-related sanctions. The EU Blocking Statute aims to counteract the effects of the U.S. secondary sanctions.
Tenaris ceased all deliveries of products and services to Iran by the end of October 2018, that is, during the wind-down period and before the full reinstatement of U.S. secondary sanctions on November 5, 2018. Tenaris did not, directly or indirectly, deliver any goods or services to Iran or Iranian companies during 2024 and does not intend to explore any commercial opportunities in Iran, nor does it intend to participate in tender offers by, or issue offers to provide products or services to, Iranian companies or their subsidiaries.
As of December 31, 2022, Tenaris’s subsidiary, Tenaris Global Services S.A. maintains an open balance for an advance made by Toos Payvand Co. for approximately EUR 0.04 million (approximately $0.04 million) for goods that remained undelivered following the reinstatement of U.S. secondary sanctions.
All revenue and profit derived from Tenaris’s sales to Iran was recorded in the fiscal year in which such sales were performed and, therefore, no revenue and profit has been reported in connection with commercial activities related to Iran for the year ended December 31, 2024.
Tenaris has procedures in place designed to ensure that its activities comply with all applicable U.S. and other international export control and economic sanctions laws and regulations.
Other Affiliates
Except for Tenaris, no other affiliates of Ternium S.A. reported any Iran related activity for the year ended December 31, 2024.

None.
Item 5.    Operating and Financial Review and Prospects
The following discussion and analysis of our financial condition and results of operations is based on, and should be read in conjunction with, our consolidated financial statements and the related notes included in this annual report. This discussion and analysis presents our financial condition and results of operations on a consolidated basis.
In its annual report for the year 2023, the company reported its results in three operating segments: Steel, Mining and Usiminas. This was the result of the consolidation of Usiminas beginning in July 2023. As of March 31, 2024, following the acquisition of an additional participation in Usiminas on July 3, 2023, the Chief Operating Decision Maker performed a review of the new business structure to decide on the allocation of resources and the assessment of performance, and decided to organize the Company in two operating segments: Steel and Mining. For additional information see note 5 to the consolidated financial statements included in this annual report.

Certain information contained in this discussion and analysis and presented elsewhere in this annual report, including information with respect to our plans and strategies for our business, includes forward-looking statements that involve risks and uncertainties. For further information, see “Cautionary Statement Concerning Forward-Looking Statements.” In evaluating this discussion and analysis, you should specifically consider the various risk factors identified in Item 3.D. “Key Information – Risk Factors” in this annual report and others that could cause results to differ materially from those expressed in such forward-looking statements.
Overview
For a description of Ternium’s profile, business strategy and sustainability approach, see Item 4. “Information on the Company—Overview”, “Information on the Company—B. Business Overview—Our Business Strategy” and “Information on the Company—B. Business Overview—Environmental, Social and Governance.”
Ternium’s revenues are affected by general global trends in the steel industry and more specifically by the economic conditions in the countries in which it has manufacturing operations and where its customers are located. Ternium’s revenues are also impacted by events that affect the price and availability of raw materials, slabs, energy and other inputs needed for its operations. Furthermore, due to the highly cyclical nature of the steel industry, recent results may not be indicative of future performance, and historical results may not be comparable to future results. Investors should not rely on the results of a single period, particularly a period of peak prices, as an indication of Ternium’s annual results or future performance. The variables and trends mentioned below could also affect the results of its investments in steel related companies.
89


Ternium’s primary source of revenue is the sale of steel products. Management expects sales of steel products to continue to be Ternium’s primary source of revenue. The global market for such steel products is highly competitive, with the primary competitive factors being price, cost, product quality and customer service. The majority of Ternium’s sales are concentrated in the Americas. Specifically, Ternium’s largest markets are Mexico, Brazil, Argentina, the United States and Colombia.
Ternium’s results are sensitive to economic activity and steel consumption. Ternium’s results of operations, which primarily depend on economic conditions in Mexico, Brazil and Argentina, are also influenced by economic conditions in international and regional markets such as the United States, Mercosur and the Andean Community. Historically, annual steel consumption in the countries where Ternium operates has varied at a rate that is linked to the annual change in each country’s gross domestic product and per capita disposable income. A protracted global recession or a depression would have a material adverse effect on the steel industry and Ternium.
Ternium’s results are also sensitive to prices in the international steel markets. Steel prices are volatile and are sensitive to supply conditions and to trends in cyclical industries, such as the construction, automotive, appliance and machinery industries, which are significant markets for Ternium’s finished steel products. For example, U.S. prices of hot-rolled coils bottomed in 2020 to $485 per ton, peaked at $2,135 per ton in 2021, and then showed significant volatility. As a result of these developments, Ternium’s operating income decreased 43% year-over-year in 2024 after decreasing 19% year-over-year in 2023 and 49% year-over-year in 2022 and increasing 388% year-over-year in 2021. Persistently low steel prices would have a material adverse effect on Ternium’s results, as could price volatility.

Trends in the steel industry may also have an impact on Ternium’s results. In addition to economic conditions and prices, the steel industry is affected by other factors such as worldwide and regional production capacity, fluctuations in steel imports/exports and tariffs. Historically, the steel industry has suffered, especially on downturn cycles, from substantial over-capacity. Over-capacity has been particularly severe in China. In addition, there are several new steel making and steel processing facilities under construction or ramping-up in North America, which could contribute to an excess of steel supply in the region. For further information on Ternium’s competition in the Mexican market see Item 4. “Information on the Company—B. Business Overview—Competition—Steel—Mexico”. Furthermore, there has been a trend toward steel industry consolidation among Ternium’s competitors, and current competitors in the steel market could become larger in the future. Intense competition could impact Ternium’s share in certain markets and adversely affect its sales and revenues.

Ternium’s production levels and costs are sensitive to the price and availability of raw materials, semi-finished steel and energy, which reflect supply and demand factors in the global steel industry. Ternium purchases substantial quantities of raw materials (including iron ore, coal, ferroalloys and scrap) and slabs for use in the production of its steel products. The availability and price of these and other inputs vary, sometimes significantly, according to multiple factors, including market conditions, government regulations or intervention, including import controls and international sanctions, allocation by suppliers and interruptions in production. In addition to raw materials and slabs, natural gas is an important component of Ternium’s cost structure. Ternium generally purchases these inputs at market or market-based prices; accordingly, price fluctuations in these inputs (which may also vary according to the above-mentioned factors) impact Ternium’s production volume and production cost. Purchased slabs are a key component of Ternium’s production process. Industry consolidation and integration of slab making facilities into finished steel products have been reducing the availability of slabs in the global market. For example, in 2023 ArcelorMittal acquired Companhia Siderúrgica do Pecém (CSP), a Brazilian slab maker that used to be a significant supplier of slabs in the international markets. In addition, ArcelorMittal gradually integrated its slab facility in Lázaro Cárdenas, Mexico, with the steel processing facilities located in Alabama, United States, that it had acquired together with NSC in February 2014. Furthermore, in 2021 ArcelorMittal inaugurated a new hot-rolling mill in Lázaro Cárdenas that led to a further integration of its slab facility in that site. Additionally, the start of the Russia-Ukraine war in February 2022 and the consequent wave of trade sanctions imposed by the United States, the United Kingdom and the European Union, among other countries, against certain Russian institutions, companies and citizens, resulted in a disruption to the global supply of slabs and other inputs consumed in the steel production process. New or continued international sanctions against Russian steel companies or citizens could result in slab scarcity and/or increases in slab prices in the market, which could have a material adverse effect on Ternium’s business and results of operations.

Ternium’s export revenues could be affected by trade restrictions and its domestic revenues could be affected by unfair competition from imports. Currently, there are a significant number of anti-dumping, countervailing, safeguard measures, tariffs and other trade-restrictive actions. Ternium’s ability to profitably access the export markets may be adversely affected by trade restrictions, including anti-dumping duties, tariffs and countervailing measures, in certain markets. In addition, Ternium’s ability to sell some steel products in its principal markets could be affected by unfair competition from imports of those steel products from certain countries, if measures against unfair trade are not in force. These trade measures could stimulate aggressive export offers elsewhere, exerting downward pressure on sales and margins of steel companies operating in other markets and regions, including those in which Ternium operates.

For further information, see Item 4. “Information on the Company—B. Business Overview—Regulations—Trade Regulations.”

Ternium’s results are sensitive to changes to trade regulations in the USMCA region. A significant share of Ternium’s sales is made to customers in Mexico. In addition, a significant portion of Ternium’s sales in Mexico are directed to the Mexican manufacturing industry, particularly the automotive industry, which in turn exports a large share of its production to the U.S. market. Our business could be materially and adversely affected by changes to trade regulations in the USMCA region. For further information on changes in existing trade arrangements between Mexico and the U.S. see Item 3. “Risk factors—Risks Relating to the Countries in Which Ternium Operates—Mexico—Changes in existing trade arrangements between Mexico and the U.S. and controversies or disputes between USMCA member countries could adversely impact Ternium’s results of operations and net results”.
Changes in prevailing exchange rates could impact results from subsidiaries with net short or long positions in currencies other than their functional currencies. The functional currency of Ternium Mexico, Ternium Argentina, Ternium Brazil, Ternium Colombia, Ternium Guatemala and Tenigal is the U.S. dollar. These subsidiaries record foreign exchange results on their net non-U.S. dollar positions when the other currencies appreciate or depreciate with respect to the U.S. dollar. In addition, these subsidiaries record deferred tax results when the local currency appreciates or depreciates in relation to the U.S. dollar (their functional currency) as such fluctuations change, in U.S. dollar terms, the tax base used to calculate deferred tax at such subsidiaries. Fluctuations in the value of such local currencies against the U.S. dollar have had, and may also have in the future, an impact on Ternium’s results. In addition, Usiminas, which we began to consolidate in July 2023, uses the Brazilian real as its functional currency. Accordingly, any fluctuation of the BRL exchange rate will impact non-BRL balances’ exposure in Usiminas’ balance sheet, including any U.S. dollar balance exposure, and, therefore, impact Ternium’s balance sheet and results of operations.
Changes in prevailing exchange rates have had an impact on Ternium’s comprehensive results in the past and could impact comprehensive results from investments with a functional currency other than the U.S. dollar in the future. In accordance with IFRS, Ternium records currency translation adjustments in its consolidated statements of comprehensive income. These adjustments do not affect net income but, instead, have an impact on net worth. Fluctuations in the Brazilian real (as our participation in Usiminas is denominated in Brazilian reais) against the U.S. dollar have had, and may also have in the future, an impact on Ternium’s comprehensive results. Ternium’s currency translation adjustments results included the effect of the fluctuation of the Brazilian real on the value of Ternium’s investment in Usiminas as measured in U.S. dollars, amounting to a loss of $824 million in 2024, a loss of $9 million in 2023 and a gain of $41 million in 2022.
The fair value of Ternium’s holdings of Argentine securities could be reduced, and Ternium may be required to record a significant loss in its consolidated income statements, as a result of a significant volatility in the Argentine financial market, foreign exchange restrictions in the country and valuation adjustments resulting therefrom. Existing foreign exchange controls in Argentina currently limit the purchase and transfer abroad of foreign currency for saving purposes, restricting Ternium Argentina’s ability to hold excess cash reserves in foreign bank accounts. Accordingly, Ternium Argentina holds its cash and financial investments in the Argentine financial system. As of December 31, 2024, the fair value of Ternium Argentina’s cash and cash equivalents and other investments was $1.3 billion, a large share of which consisted of bond holdings. The U.S. dollar value of such instruments recorded in Ternium’s consolidated financial statements is based on their Argentine peso local market price, converted to the U.S. dollar at the ARS/$ official exchange rate. The valuation of such investments is subject to the volatility of the Argentine financial market and to the effects of applicable foreign exchange restrictions. For example, the fair value of Argentine securities holdings decreased by $555 million in 2023, mostly as a result of a significant devaluation of the Argentine peso in December, 2023, and increased by $457 million in 2024, largely due to the favorable reaction by investors to the reforms undertaken by the Milei administration, which was mostly recorded as changes in the fair value of financial instruments in Other Comprehensive Income. As of December 31, 2024, the balance of Ternium’s Other Comprehensive Income in connection with its Argentine sovereign bond holdings amounted to $80 million.

Fiscal Year Ended December 31, 2024 compared to Fiscal Year Ended December 31, 2023
This annual report includes certain non-IFRS alternative performance measures such as “Net Cash” and “Free Cash Flow”. The reconciliation of these figures to the most directly comparable IFRS measures is included in Exhibit 15.1 "Statement explaining alternative performance measures".
Overview
In 2024, Ternium continued making progress in its expansion program at the Pesquería Industrial Center. The company commenced the construction of the new steel slab and direct reduction plants, continued building the new cold-rolling and galvanizing facilities, and started the ramp-up of the new push-pull pickling line and new finishing facilities. In Argentina, we successfully commissioned our new wind farm in the fourth quarter of 2024 and, in Brazil, Usiminas successfully ramped-up its main blast furnace at the Ipatinga facility, following its relining in 2023.
These achievements are contributing to further strengthening Ternium’s competitive position in Latin America. The new push-pull pickling line has broadened the product offering for our Mexican industrial customers, and the downstream lines under construction will further enhance our positioning in the region. In Argentina, the new wind farm complements the company’s power plant, which utilizes recycled gases from its steelmaking operations. Together, these facilities generate nearly all the electricity required for the company’s operations in the country. In Brazil, Usiminas improved its cost structure, enhanced its operational efficiency and increased steel production following the blast furnace relining.
93


Total shipments increased by 10% year-over-year in 2024, primarily due to the full-year consolidation of Usiminas’ results, partially offset by lower sales volumes in the Southern Region.

Steel Shipments in 2024
2199023413109
In Mexico, steel shipments in 2024 remained relatively stable year-over-year following a 22% expansion in 2023. Throughout the year, the weakness in the commercial market was largely offset by the continued growth of Ternium’s steel shipments to industrial customers. Among the various industrial sectors, vehicle manufacturing stood out with a 6% year-over-year increase in 2024, achieving a new record-high production of 4.0 million units. Conversely, by the end of the year, the Mexican commercial market was negatively influenced by uncertainties arising from an increase in trade frictions with the United States. In addition, construction activity in 2024 faced a year-over-year decline reflecting weak government infrastructure investment. This decline was partially mitigated by stronger residential construction activity.
In Brazil, apparent steel demand for flat steel products grew by 10% year-over-year in 2024. Usiminas successfully capitalized on this favorable scenario despite facing substantial steel imports into the country, aided by improved operating performance. Shipments to the automotive sector were bolstered by a 10% year-over-year expansion in vehicle manufacturing, which reached 2.6 million vehicles in 2024. Steel shipments to industrial customers and the commercial market also grew. With Ternium fully consolidating Usiminas’ results from July 2023 onwards, reported steel shipments for 2024 saw a significant increase compared to those of 2023.
In the Southern Region, the company experienced a 20% year-over-year decrease in steel shipments in 2024. This decline was primarily due to the effects of the Argentine government’s economic stabilization measures on local activity, which had a significant impact on shipments in the first quarter followed by a gradual recovery throughout the year.
In Other Markets, steel sales volumes improved across the board, following a relatively weak performance in 2023.
In 2024, Ternium recorded a $410 million provision for ongoing litigation related to the acquisition of a participation in Usiminas in 2012. During the year, the Brazilian Superior Court of Justice ordered Ternium’s subsidiaries Ternium Investments and Ternium Argentina, together with Tenaris’s subsidiary Confab (all of which compose the T/T Group under the Usiminas shareholders agreement), to pay CSN an indemnification in connection with their 2012 acquisition of a participation in Usiminas. For more information on this topic, see Note 25(i)(a) “Provision for ongoing litigation related to the acquisition of a participation in Usiminas” to our consolidated financial statements included in this annual report.
Ternium’s net income totaled $174 million in 2024, including operating income of $1.3 billion, deferred tax losses of $231 million, a financial result loss of $194 million and the $410 million aforementioned provision regarding the ongoing litigation related to the acquisition of a participation in Usiminas in 2012.
In 2024, dividends paid to Ternium S.A.’s shareholders amounted to $609 million. Capital expenditures for the year reached $1.9 billion, including capital expenditures relating to Ternium’s progress in the expansion of the Pesquería Industrial Center and the construction of the new wind farm in Argentina.
94


Despite these significant cash disbursements, the company’s net cash position at the end of 2024 was $1.6 billion. Strong operating cash flow of $1.9 billion and a $457 million increase in the fair value of financial instruments helped maintain a solid financial position.
On February 18, 2025, the board of directors proposed that an annual dividend of $2.70 per ADS be approved at the annual general shareholders meeting, which is scheduled to be held on May 6, 2025.
Net Sales and Shipments
The Steel Segment’s net sales were stable year-over-year in 2024, as lower realized steel prices and lower sales volumes in the Southern Region were largely offset by the full year consolidation of Usiminas’ results, which Ternium started to consolidate from July 2023 onward.
The Mining Segment’s net sales to third parties increased by 30% year-over-year, driven by an increase in iron ore shipments partially offset by a decline in realized iron ore prices. The year-over-year increase in iron ore shipments primarily reflected the full consolidation of Usiminas’ results, partially offset by lower production levels in our Mexican and Brazilian operations.

Note: Does not include intercompany net sales and shipments of iron ore. “Other products” includes mainly electricity sales in Mexico and Brazil.
Operating Income
Ternium’s operating income decreased year-over-year in 2024, mainly due to a $116 lower steel revenue per ton. This was partially offset by the full consolidation of Usiminas’ results and a decrease in cost per ton of steel, which, however, continued to lag behind the reduction in raw material and slab market prices.

Net Financial Results
Net financial results showed a loss of $194 million in 2024. This result included a loss of $121 million due to Ternium’s divestment of Argentine government bond holdings, which triggered the recycling of changes in the fair value of financial instruments from Other Comprehensive Income to Financial Results.
Additionally, net financial results showed a $104 million net foreign exchange loss in 2024, primarily due to the adverse effects of the Brazilian Real’s depreciation against the US dollar on Usiminas’ U.S. dollar denominated financial debt, given that Usiminas utilizes the Brazilian Real as its functional currency.

Provision for Ongoing Litigation Related to the Acquisition of a Participation in Usiminas
In 2024, the company recorded a $410 million provision for ongoing litigation related to the acquisition of a participation in Usiminas in 2012. For more information on this topic, see note 25(i)(a) “Provision for ongoing litigation related to the acquisition of a participation in Usiminas” to our consolidated financial statements included in this annual report.

Income Tax Expense
Ternium Mexico, Ternium Argentina and Ternium Brasil use the U.S. dollar as their functional currency and are, therefore, affected by deferred tax results. These results account for the impact of local currency fluctuations against the U.S. dollar, as well as for the effect of local inflation. Deferred tax losses in 2024 mainly reflected the significant depreciation of the Mexican Peso and the Brazilian Real against the U.S. dollar.

Changes in cash and cash equivalents between December 31, 2023 and December 31, 2024
Overview
In 2024, cash from operations reached $1.9 billion, with working capital remaining relatively unchanged year-over-year. Capital expenditures amounted to $1.9 billion in the same year. Throughout 2024, the company progressed with the construction of the new downstream and upstream facilities in the Pesquería Industrial Center including the start-up of a new push-pull pickling line and finishing facilities, and built a new wind farm in Argentina. Furthermore, the company moved forward with several projects aimed at improving environmental and safety conditions throughout its main facilities.

In 2024, alongside the development of its capital expenditure program, Ternium paid dividends totaling $609 million to its shareholders and $54 million to minority interests. Despite these significant cash disbursements, Ternium maintained a robust Net Cash position of $1.6 billion as of December 31, 2024. This was supported by the aforementioned cash generated from operating activities and a $457 million increase in the fair value of financial instruments.

Ternium’s net cash position as of December 31, 2024 included Ternium Argentina’s total position of cash and cash equivalents and other investments of $1.3 billion. For information on exchange controls in Argentina, see note 30 “Foreign exchange restrictions in Argentina” to Ternium’s audited consolidated financial statements included in this annual report; and “—Risks Relating to the Countries in Which Ternium Operates – Argentina: Exchange controls in Argentina could negatively impact Ternium Argentina’s operations, preventing Ternium from importing raw materials, paying dividends or transferring cash surpluses abroad, as a result of its inability to access the foreign exchange market”.

Operating activities
Net cash provided by operating activities in 2024 included a year-over-year increase in inventories of $109 million, as higher steel and raw material inventory volumes were partially offset by lower inventory costs. In addition, trade payables and other liabilities recorded a year-over-year net decrease of $35 million in 2024. These working capital increases were largely offset by a year-over-year net decrease in trade and other receivables of $128 million amid lower realized steel prices.

Investing activities
Net cash used in investing activities in 2024 was $1.4 billion, primarily attributable to capital expenditures of $1.9 billion partially offset by a $462 million decrease in financial investments with maturities of more than three months.

Financing activities
Net cash used in financing activities was $488 million in 2024, attributable to dividends paid in cash to Ternium S.A.’s shareholders of $609 million and to non-controlling interest of $54 million, as well as to finance lease payments of $61 million, partially offset by net proceeds from borrowings of $236 million.

For a discussion and analysis of changes in cash and cash equivalents between December 31, 2022 and December 31, 2023, see Ternium's Annual Report on Form 20-F filed with the Securities and Exchange Commission on March 27, 2024.

Principal Sources of Funding
Funding Policy
Management’s policy is to ensure a high degree of flexibility in operating and investment activities by maintaining adequate liquidity levels and securing access to readily available sources of financing. When possible, management makes its financing decisions, including the choice of currency, term and type of the facility, based on the intended use of proceeds for the proposed financing and based on costs. For information on our financial risk management, see note 29 “Financial risk management” to our consolidated financial statements included in this annual report.

Ternium maintains non-committed credit facilities and management is confident that Ternium has adequate access to the credit markets. Considering our financial position and the funds provided by operating activities, management believes that we have sufficient resources to satisfy our current working capital needs, service our debt and pay dividends. Management also believes that our liquidity and capital resources give us adequate flexibility to manage our planned capital spending programs and to address short-term changes in business conditions.

Financial Liabilities

E.    Critical Accounting Estimates
This discussion and analysis of our operating and financial review and prospects is based on the audited consolidated financial statements included in this annual report, which have been prepared in accordance with IFRS. IFRS differs in certain significant aspects from U.S. GAAP.
The preparation of financial statements in conformity with IFRS requires management to make estimates and judgements that affect the reported amounts of assets, liabilities, revenues and expenses, and the related disclosure of contingent assets and liabilities. Estimates and judgments are continually evaluated and are based on historical experience and other factors, including expectations of future events, that are believed to be reasonable under the circumstances. Management makes estimates and assumptions concerning the future. These estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Although management believes that these estimates and assumptions are reasonable, they are based upon information available at the time they are made. Actual results may differ significantly from these estimates under different assumptions or conditions.

An overview of Ternium’s critical accounting policies under which significant judgments, estimates and assumptions are made may be found in note 4(bb) to the consolidated financial statements included in this annual report.

Item 6.    Directors, Senior Management and Employees
A.    Directors and Senior Management
Board of Directors
Management is vested in a board of directors with the broadest power to act on behalf of the company and to accomplish or authorize all acts and transactions of management and disposal that are within its corporate purpose and not specifically reserved in the articles of association or by applicable law to the general shareholders’ meeting. Ternium S.A.'s articles of association provide for a board of directors consisting of a minimum of three and a maximum of fifteen directors; however, for as long as Ternium S.A's shares are listed on at least one regulated market, the minimum number of directors must be five. The current board of directors is composed of eight directors.
The board of directors is required to meet as often as required by the interests of the company and at least four times per year. In 2024, the board of directors met six times. A majority of the members of the board of directors in office present or represented at the board of directors' meeting constitutes a quorum, and resolutions of the board of directors may be adopted by the vote of a majority of the directors present or represented. In case of a tie, the chairman is entitled to cast the deciding vote.
Directors are elected at the annual ordinary general shareholders’ meeting to serve one-year renewable terms, as determined by the general shareholders’ meeting. The general shareholders’ meeting also determines the number of directors that will constitute the board and their compensation. The general shareholders’ meeting may dismiss all or any member of the board of directors at any time, with or without cause, by resolution passed by a simple majority vote.

On January 9, 2006, Tenaris and a wholly owned subsidiary of San Faustin entered into a shareholders’ agreement, pursuant to which the San Faustin subsidiary is required to take all actions in its power to cause one of the members of Ternium S.A.'s board of directors to be nominated by Tenaris and any directors nominated by Tenaris to be removed only pursuant to written instructions by Tenaris. Tenaris and the San Faustin subsidiary also agreed to cause any vacancies on the board of directors to be filled with new directors nominated by either Tenaris or the San Faustin subsidiary, as applicable. On April 27, 2007, the San Faustin subsidiary assigned all of its rights and obligations under the shareholders’ agreement to Techint. The shareholders’ agreement will remain in effect so long as each of the parties holds at least 5% of the shares of Ternium S.A. or until it is terminated by either Tenaris or Techint pursuant to its terms. Mrs. Alicia Lucía Móndolo has been nominated by Tenaris as director of Ternium S.A. pursuant to such shareholders' agreement.
Ternium S.A.'s articles of association provide that the board of directors may, within the limits of applicable law, (a) delegate to one or more persons, whether or not members of the board of directors, the day-to-day management and the authority to represent Ternium S.A., provided, however, that the delegation of the day-to-day management and representation authority to a member of the board of directors shall be subject to the prior authorization of the general shareholders' meeting, (b) delegate to one or more persons, whether or not members of the board of directors, the powers necessary to carry out corporate decisions (except for approval of material transactions with related parties), (c) confer to one or more persons, whether or not members of the board of directors, the powers deemed to be appropriate for the general technical, administrative and commercial management, and (d) constitute and determine the responsibilities, powers and authority (including without limitation an audit committee), the members of which may be selected either from among the directors or outside thereof. On April 30, 2024, the board of directors appointed the Chief Executive Officer as administrateur délégué and delegated to him the power to manage the corporate affairs within the ordinary course of business, to direct and supervise the business activities of Ternium S.A.'s subsidiaries and to represent it in relation to such matters.
On April 30, 2024, the annual general shareholders’ meeting resolved to maintain the number of directors at eight and approved the re-election of Mr. Roberto Bonatti, Mr. Carlos Alberto Condorelli, Mr. Vincent Robert Gilles Decalf, Ms. Gioia Ghezzi, Mr. Daniel Agustín Novegil, Mr. Gianfelice Mario Rocca, Mr. Paolo Rocca and Ms. Lorenza Martinez Trigueros as board members, to hold office until the annual general shareholders’ meeting, which is scheduled to be held on May 6, 2025.

Directors' Liability
Each director must act in the interest of the company, and in accordance with applicable laws, regulations, and the articles of association. Directors are also bound by a general duty of care owed to the company.
Under the Luxembourg law of August 10, 1915 on commercial companies, as amended (the "Luxembourg Company Law"), directors may be liable to Ternium S.A. in accordance with general law for the execution of their mandate and for any misconduct in the management of the corporate affairs. Directors are jointly and severally liable towards either Ternium S.A. or any third parties from damages resulting from the violation of the Luxembourg Company Law or the articles of association. Directors shall be discharged from such liability in the case of a violation to which they were not a party, provided no misconduct is attributable to them and such violation has been reported to the first general meeting of shareholders after they have acquired knowledge thereof.
Causes of action against directors for damages may be initiated by Ternium S.A. upon a resolution of the general shareholders’ meeting passed by a simple majority vote, irrespective of the number of shares represented at the meeting. Causes of action against directors who misappropriate corporate assets or commit a breach of trust may be brought by any shareholder for personal losses different from those of the company.
An action may also be brought against the directors on behalf of Ternium S.A. by shareholders who, at the general meeting which decided upon discharge of such directors or members, owned voting securities representing at least ten per cent of the votes attaching to all such securities.
It is customary in Luxembourg that the shareholders expressly discharge the members of the board of directors from any liability arising out of or in connection with the exercise of their mandate when approving the annual accounts at the annual general shareholders’ meeting.
103


However, such discharge will not release the directors from liability for any damage caused by unrevealed acts of mismanagement or unrevealed breaches of Luxembourg Company Law or the articles of association, nor will it release directors from liability for any personal loss of the shareholders independent and separate from the losses suffered by the company due to a breach either revealed or unrevealed of either the Luxembourg Company Law or the articles of association.
Under Luxembourg law, unless the decision of the board of directors relates to ordinary business entered into under normal conditions, any director having a direct or indirect financial interest conflicting with that of the company in a transaction which has to be considered by the board of directors, must advise the board thereof and cause a record of her/his statement to be included in the minutes of the meeting and may not take part in the deliberations. At the next following general meeting, before any other resolution is put to vote, a special report must be made on any transactions in which any of the directors may have had an interest conflicting with that of the company.
External auditors
Ternium S.A’s articles of association require the appointment of an independent audit firm in accordance with applicable law. External auditors are appointed by the general shareholders' meeting, upon recommendation from the audit committee, through a resolution passed by a simple majority vote, to serve a one-year renewable term. The primary responsibility of the external auditors is to audit the annual accounts and consolidated financial statements and to submit a report on the accounts to shareholders at the annual general shareholders' meeting. In accordance with applicable law, statutory auditors (réviseur d'entreprises) must meet certain conditions of professional qualification and good reputation verified by the Luxembourg Financial Sector Supervisory Commission (Commission de Surveillance du Secteur Financier) and be registered as members of the Luxembourg Institute of Independent Auditors (Institut des réviseurs d’entreprises).
The external auditors may be dismissed for reasonable cause by the general shareholders' meeting at any time, at the board of director's recommendation or, if the shares of Ternium S.A. are listed on a regulated market, at the audit committee's recommendation. Luxembourg law does not allow directors to serve concurrently as external auditors. As part of their duties, the auditors report directly to the audit committee.
Pursuant to its charter, the audit committee is responsible for, among other things, the oversight of the independence and performance of the external auditors. The audit committee is also responsible to consider and make recommendations to the board of directors, to be put to shareholders for approval at the annual general meeting of shareholders, regarding the appointment, re-appointment or removal of the external auditors. In addition, the audit committee is responsible to review the appropriateness and provision of permitted non-audit fees and to review and approve any fees (whether for audit, audit-related and non-audit services) payable to the external auditors. On a yearly basis, in the performance of its functions, the audit committee considers the appointment of the external auditors and reviews, together with management and the external auditor, the audit plan, audit related services and other non-audit services. The audit committee requests the board of directors to submit the audit committee’s recommendation for the appointment of the external auditor for each fiscal year and the payment of applicable fees, for final approval by the general shareholders’ meeting. The general shareholders’ meeting regularly approves such audit fees and authorizes the audit committee to approve any increase or reallocation of such audit fees as may be necessary, appropriate or desirable under the circumstances. No services outside the scope of the audit committee’s approval can be undertaken by the external auditor.

The annual general shareholders' meeting held on April 30, 2024, re-appointed PwC Luxembourg as Ternium S.A.'s statutory auditor for the fiscal year ended December 31, 2024. At the next annual general shareholders’ meeting scheduled to be held on May 6, 2025, following the recommendation of the audit committee, the board of directors will propose that PwC Luxembourg be reappointed as statutory auditors for the fiscal year ending December 31, 2025.

Audit Committee
Pursuant to Ternium S.A.’s articles of association, as supplemented by the audit committee’s charter, for as long as its shares are listed on at least one regulated market, Ternium S.A. must have an audit committee composed of at least three members, the majority of whom must qualify as independent directors, provided, however, that the composition and membership of the audit committee shall satisfy such requirements as are applicable to, and mandatory for, audit committees of issuers such as Ternium S.A. under any applicable law, rule or regulation (including, without limitation, the applicable laws, rules and regulations of such regulated market or markets).
Under the articles of association, an independent director is a director who:
(i)is not employed, and has not been employed in an executive capacity by Ternium S.A. or any of its subsidiaries within the five years preceding the ordinary general shareholders’ meeting at which the candidate for the board of directors was voted upon;
(ii)does not receive consulting, advisory or other compensatory fees from Ternium S.A. or any of its subsidiaries (other than fees received as a member of the board of directors of any committee thereof and fees received as a member of the board of directors or other governing body, or any committee thereof, of any of Ternium S.A.’s subsidiaries);
(iii)is not a person who directly or indirectly controls Ternium S.A.;
(iv)does not have, and does not control a business entity that has, a material business relationship with Ternium S.A., any of its subsidiaries or a person who directly or indirectly controls Ternium S.A., if such material business relationship would reasonably be expected to adversely affect the director’s ability to properly discharge his or her duties;
(v)does not control directly or indirectly, and is not and has not been, within the five years preceding the ordinary general shareholders’ meeting at which the candidate for the board of directors was voted upon, employed by a present or former internal or external auditor of Ternium S.A., any of its subsidiaries or a person who directly or indirectly controls Ternium S.A.; and
(vi)is not a spouse, parent, sibling or relative up to the third degree of, and does not share a home with, any of the persons listed above.
The audit committee currently consists of three members, Ms. Gioia Ghezzi, Mr. Vincent Robert Gilles Decalf and Mrs. Lorenza Martinez Trigueros. The current members of the audit committee were appointed by the board of directors on April 30, 2024. As of the date of this annual report, all members of the audit committee qualify as independent directors both for purposes of Exchange Act Rule 10A-3(b)(1) and under the articles of association. Mr. Decalf serves as chairperson of the audit committee.
The audit committee operates under a charter that was amended and restated by the board of directors on November 2, 2021. The audit committee assists the board of directors in fulfilling its oversight responsibilities with respect to the integrity of the company’s financial statements, including periodically reporting to the board of directors on its activity; and the adequacy of the company’s systems of internal control over financial reporting. The audit committee is also responsible for making recommendations regarding the appointment, compensation, retention and oversight of, and for assessing the independence of, the external auditors (see Item 16.C “—Principal Accountant Fees and Services” for additional information about the audit committee’s procedures with respect to our independent auditors).
107


In addition, the audit committee is required by Ternium S.A.’s articles of association and audit committee’s charter to review and, where applicable, approve material transactions between Ternium S.A. or its subsidiaries and related parties, as provided in the articles of association and audit committee’s charter, or as may be required by any applicable law, rule or regulation, in order to determine whether their terms are consistent with the interests of Ternium S.A. and all its shareholders and are consistent with market conditions or are otherwise fair to Ternium S.A. The company has adopted a Related Party Transactions Policy and Procedure setting forth consolidated guidelines and procedures for the identification, review, approval and management of related party transactions, seeking to assure transparency and substantial and procedural fairness of such transactions, as well as compliance with the provisions in the articles of association and the audit committee’s charter relating to transactions with related parties, as well as Luxembourg rules relating to the approval and disclosure of material related party transactions and Section 314.00 of the NYSE Listed Company Manual.
Under the articles of association, as supplemented by the Related Party Transactions Policy and Procedure, a “related party” is any of the following persons: (i) any affiliate of Ternium S.A.; (ii) any entity in which a controlling person owns a substantial interest or over which a controlling person can exercise significant influence; (iii) any unconsolidated entity in which Ternium S.A. has significant influence; (iv) any entity or individual having significant influence over Ternium S.A., or a close family member of any such individual; (v) any individual or entity that is the beneficial owner of five percent (5%) or more of the shares of Ternium S.A., including through the ownership of any securities representing shares of Ternium S.A.; (vi) any director or executive officer of any of the controlling persons, Ternium S.A. or any of the subsidiaries, or a close family member of any such director or executive officer; (vii) any entity in which a substantial interest in the voting power is owned, directly or indirectly, by any person described in (iv), (v) or (vi) above or over which such a person is able to exercise significant influence; or (viii) any entity that has a member of key management in common with Ternium S.A. or any of its subsidiaries (provided that key management personnel includes persons having authority and responsibility for planning, directing and controlling the activities of an entity, including directors and executive officers and close family members of any such individuals).
With respect to the materiality threshold for review and approval of related party transactions, the articles of association, as supplemented by the audit committee’s charter and the Related Party Transactions Policy and Procedure, provide that the following related party transactions, which are qualified as “Level 1” related party transactions, are subject to review by the audit committee, which shall make a recommendation to the board of directors as to either reject or approve the proposed related party transaction:
(i)     any transaction between Ternium S.A. or its subsidiaries with related parties (i) with an individual value equal to or greater than $10 million, or its equivalent in other currencies, or (ii) with an individual value lower than $10 million, or its equivalent in other currencies, when the aggregate sum reflected in the financial statements of the four fiscal quarters preceding the date of determination- of any series of transactions for such lower value that can be deemed to be parts of a unique or single transaction (but excluding any transactions that were reviewed and approved by the audit committee or board of directors, as applicable, or the independent members of the board of directors of any of its subsidiaries) exceeds 1.5% of the company’s consolidated net sales made in the fiscal year preceding the year on which the determination is made; and
(ii)    any corporate reorganization transaction (including a merger, spin-off or bulk transfer of a business) affecting Ternium S.A. or any of its subsidiaries for the benefit of, or involving, a related party.
In addition, any related party transaction that does not qualify as a “Level 1” related party transaction, but which has an individual value equal to or higher than such value threshold as management may from time to time determine as material to the company for disclosure purposes under Item 7.B of this annual report, qualifies as a “Level 2” related party transaction and must be reviewed by the audit committee for purposes of making a determination as to whether any conflicts of interest exist and whether the proposed related party transaction is consistent with the interests of the company and all shareholders, in order to either reject or approve the proposed transaction. Any related party transaction that is less than such value qualifies as a “Level 3” related party transaction and is reviewed by the company’s related-party transaction unit, the area within the company responsible for centralizing and compiling the information relating to all related party transactions and performing the review, assessment and other procedures contemplated in the Related Party Transactions Policy and Procedure. In addition, the current Related Party Transactions Policy and Procedure provides that, at least on a quarterly basis, the company's related-party transaction unit must submit to the audit committee a summary cumulative report of all related-party transactions approved pursuant to the Related Party Transactions Policy and Procedure and must provide any additional information as the audit committee may request.
108


The audit committee has the power (to the maximum extent permitted by applicable laws) to request that Ternium S.A. or relevant subsidiary promptly provide all information necessary for the audit committee to assess the material transactions with related parties that it is required to review. In no event may any proposed related party transaction be entered into or otherwise be given effect unless it has been reviewed and approved in accordance with the Related Party Transactions Policy and Procedure. Any executed transaction that has not been duly reviewed and approved must be promptly submitted for review in accordance with applicable procedures and, if determined appropriate, must be ratified; if the transaction is not ratified, it must be modified to make it acceptable for ratification or it must otherwise be immediately discontinued or rescinded.
The audit committee is also in charge of the interpretation, implementation, control and enforcement of Ternium's Clawback Policy (the "Clawback Policy"), which sets forth the principles for the prompt recovery of erroneously awarded incentive-based compensation granted to certain officers in the event of a restatement of the company’s financial statements.

The audit committee also performs other duties imposed by applicable laws, and by regulations of the markets on which Ternium S.A.'s securities are listed, as well as any other duty entrusted to it by the board of directors.

The audit committee has the authority to conduct any investigation appropriate to the fulfilment of its responsibilities and has direct access to the external auditors as well as anyone in the company and, subject to applicable laws and regulations, its subsidiaries. In addition, the audit committee may engage, at the company's expense, independent counsel and other internal or external advisors to review, investigate or otherwise advise on, any matter as the committee may determine to be necessary to carry out its purposes and responsibilities.

Item 8.    Financial Information
A.    Consolidated Statements and Other Financial Information
See Item 18 and pages F-1 through F-98 for Ternium’s consolidated financial statements.
Legal Proceedings
Ternium is from time to time subject to various claims, lawsuits and other legal proceedings, including customer, employee, tax and environmental-related claims, in which third parties are seeking payment for alleged damages, reimbursement for losses or indemnity. Management with the assistance of legal counsel periodically reviews the status of each significant matter and assesses potential financial exposure.

Some of these claims, lawsuits and other legal proceedings involve highly complex issues, and often these issues are subject to substantial uncertainties and, therefore, the probability of loss and an estimation of damages are difficult to ascertain. Accordingly, with respect to a large portion of such claims, lawsuits and other legal proceedings, Ternium is unable to make a reliable estimate of the expected financial effect that will result from the ultimate resolution of such proceeding. In those cases, Ternium has not accrued a provision for the potential outcome of these cases.

If a potential loss from a claim, lawsuit or other proceeding is considered probable and the amount can be reasonably estimated, a provision is recorded. Accruals for loss contingencies reflect a reasonable estimate of the losses to be incurred based on information available to management as of the date of preparation of the financial statements and take into consideration litigation and settlement strategies. In a limited number of ongoing cases, Ternium was able to make a reliable estimate of the expected loss or range of probable loss and has accrued a provision for such loss but believes that publication of this information on a case-by-case basis would seriously prejudice Ternium’s position in the ongoing legal proceedings or in any related settlement discussions. Accordingly, in these cases, the company has disclosed information with respect to the nature of the contingency but has not disclosed its estimate of the range of potential loss.

The company believes that the aggregate provisions recorded for potential losses in its consolidated financial statements are adequate based upon currently available information. However, if management’s estimates prove incorrect, current reserves could be inadequate and Ternium could incur a charge to earnings, which could have a material adverse effect on Ternium’s results of operations, financial condition, net worth and cash flows.

Outstanding Legal Proceedings
The following legal proceedings were outstanding as of the date of this report:
Ongoing litigation related to the acquisition of a participation in Usiminas
The company is party to a long standing lawsuit filed in Brazil by CSN and various entities affiliated with CSN against Ternium Investments, its subsidiary Ternium Argentina, and Tenaris’s subsidiary Confab, all of which compose the T/T Group under the Usiminas shareholders agreement. The entities named in the CSN lawsuit had acquired participations in Usiminas in January 2012. The CSN lawsuit alleges that, under applicable Brazilian laws and rules, the acquirers were required to launch a tag-along tender offer to all non-controlling holders of Usiminas ordinary shares for a price per share equal to 80% of the price per share paid in such acquisition, or BRL 28.8, and seeks an order to compel the acquirers to launch an offer at that price plus interest. If so ordered, the offer would need to be made to 182,609,851 ordinary shares of Usiminas not belonging to the Usiminas control group. Ternium Investments and Ternium Argentina’s respective shares in the offer would be 60.6% and 21.5%.

On September 23, 2013, the first instance court dismissed the CSN lawsuit, and on February 8, 2017, the court of appeals maintained the understanding of the first instance court. CSN filed an appeal to the Superior Court of Justice ("SCJ"), seeking the review and reversal of the decision issued by the Court of Appeals, and on March 7, 2023, the SCJ, by majority vote, rejected CSN’s appeal.

CSN made several submissions in connection with the SCJ decision, including a motion for clarification that challenged the merits of the SCJ decision. Decisions at the SCJ are adopted by majority vote. At an October 17, 2023 session, two justices of the SCJ voted in favor of remanding the case to the first instance for it to be retried following production and assessment of the new evidence, and two justices of the SCJ voted, without requiring any further evidence, in favor of granting CSN’s motion for clarification and reversing the March 7, 2023 decision that rejected CSN’s appeal; because the fifth member of SCJ excused himself from voting, a justice from another panel at the SCJ was summoned to produce the tie-breaking vote.
114


On June 18, 2024, the SCJ completed its voting on CSN’s motion for clarification and reversed, by majority vote, its March 7, 2023 decision, and resolved that Ternium Investments, its subsidiary Ternium Argentina and Tenaris’s subsidiary Confab should pay CSN an indemnification in connection with the acquisition by the T/T Group of the participations in Usiminas in January 2012, with CSN being allowed to retain ownership of the Usiminas ordinary shares it currently owns.

On August 1, 2024, Ternium Investments, Ternium Argentina and the other T/T Group entities filed a motion for clarification against the SCJ decision and, subsequently, CSN filed its reply. On December 6, 2024, the SCJ rejected this motion for clarification, confirming the obligation of the T/T Group entities to pay indemnification in connection with the 2012 acquisition of the participations in Usiminas. Notwithstanding the foregoing, the SCJ unanimously resolved to modify the applicable monetary adjustment mechanism and to cap the applicable attorney’s fees, thereby lowering the aggregate amount that would be payable if CSN ultimately prevails in this claim. Based on such SCJ decision, assuming monetary adjustment through December 31, 2024, and attorney’s fees in the amount of BRL5 million, the revised aggregate amount potentially payable by Ternium Investments and Ternium Argentina if CSN finally prevails on its claims would be of approximately BRL 1,875.9 million (approximately $ 302.9 million at the BRL/$ rate as of such date) and BRL 664.1 million (approximately $ 107.3 million at the BRL/$ rate as of such date), respectively.

The company continues to believe that all of CSN's claims and allegations are unsupported and without merit, as confirmed by several opinions of Brazilian legal counsel, two decisions issued by the Brazilian securities regulator in February 2012 and December 2016, the first and second instance court decisions and the March 7, 2023 SCJ decision referred to above, and that in connection with the Usiminas acquisition the T/T Group was not required to either launch a tender offer or to pay indemnification to CSN. Accordingly, on February 10, 2025, Ternium filed an extraordinary appeal against the SCJ decisions that ordered an indemnification payment, seeking their review and reversal by the Supreme Federal Tribunal. The company, however, cannot predict the ultimate resolution on the matter.

Potential Mexican income tax adjustment
In March 2015, as part of a tax audit with respect to fiscal year 2008, the Mexican tax authority (the “SAT”) challenged the deduction by Ternium Mexico of a tax loss arising from an intercompany sale of shares in December 2008. In addition, in September 2018, as part of a tax audit for fiscal year 2011, the SAT objected to the deduction by Ternium Mexico of the remainder of the 2008 tax loss. Ternium Mexico requested an injunction from the Mexican courts against the SAT claims and filed its defense and supporting documents with the SAT. After Ternium Mexico obtained an injunction in August 2020, in November 2020, the SAT issued a new preliminary audit report in which it reiterated its objections to the deduction of the 2008 tax loss. In June 2021, the SAT determined income tax adjustments with respect to 2008 and 2011 for amounts currently estimated at approximately $72.8 million and $ 35.6 million, respectively. Ternium Mexico appealed the SAT determinations.

More recently, however, Ternium Mexico withdrew its appeals and agreed to provide further information and documentation to the SAT. With all of the above-mentioned information and documentation, the SAT reduced the 2008 and 2011 tax adjustments downwards to approximately $17.5 million and $35.8 million, respectively. The company had a tax provision of $53.3 million already included in its consolidated condensed interim financial statements as of September 30, 2023. The payment to the SAT was made on October 9, 2023, and the company received formal documentation issued by the SAT with the closure of both audits.

Tax assessments relating to the use of certain ICMS tax credits

The Imposto Sobre Operações Relativas à Circulação de Mercadorias e Serviços (“ICMS”), is a Brazilian value-added tax on the services (inter-states) and the transfer of goods in Brazil. Payment of ICMS generates tax credits that, subject to applicable law, rules and regulations, may be either used to offset ICMS payment obligations generated in connection with domestic sales of products and services, or sold and transferred to third parties.

The Rio de Janeiro State Treasury Office is challenging the use by Ternium Brasil of ICMS tax credits generated in connection with purchases of refractory materials in the period from December 2010 through December 2016, and intends to assess taxes and impose fines on Ternium Brasil on the argument that such materials may not be qualified as “raw materials” or “intermediary products” but as “goods for consumption” and, accordingly, ICMS tax credits generated in connection with their purchase are not available and may not be used to offset ICMS payment obligations generated in connection with Ternium Brasil’s domestic sales of carbon steel slabs. Ternium Brasil has appealed against the Rio de Janeiro State Treasury Office tax assessments and fines. A provision in the amount of $ 57.7 million was recorded as of the acquisition date in connection with this matter ($29.3 million and $37.5 million as of December 31, 2024 and 2023, respectively).

BP Energía México (BPEM) - Arbitration process

On February 2022, BP Energía México (“BPEM”) started an arbitration process against GIMSA, Ternium México and Ternium Gas México (collectively, the “Respondents”), claiming payment for the gas supply from February 12 to February 28, 2021, for $27.6 million, $12.4 million, and $2.4 million, plus V.A.T. and interest, respectively. On June 9, 2024, after the arbitration process was completed, the arbitration award was notified and the Arbitration Tribunal ordered the Respondents to pay BPEM $22.0 million, $9.9 million and $2.1 million, plus V.A.T. and interest, respectively. Additionally, the Respondents were ordered to pay expenses and costs of $2.4 million. As of September 30, 2024, the company recognized a provision of $34.2 million in its consolidated condensed interim financial statements. On October 25, 2024, the parties reached an agreement settling the reciprocal claims, and all parties formally dismissed the legal actions initiated with respect to the arbitration award.

PIS and COFINS credits defense action - Usiminas

In August 2024, the Brazilian Federal Government filed two new tax claims for a total of approximately BRL503 million, or $92 million (BRL518 million or $84 million as of December 31, 2024). The contingencies are related to tax assessments that partially approved offset statements through which Usiminas claimed PIS and COFINS credits arising from a final court decision, which discussed the exclusion of ICMS from the calculation basis of said contributions. The tax authority disagreed with the calculation methodology adopted by Usiminas. Usiminas filed a defense action in the aforementioned proceedings, arguing that the calculations are correct and the credit rights should be recognized.

The annual dividend would include an interim dividend of $0.09 per share ($0.90 per ADS), or $177 million, paid in November 2024. If the board of directors’ proposal is approved at the shareholders’ meeting, a net dividend of $0.18 per share ($1.80 per ADS), or $353 million in the aggregate, will be paid on May 14, 2025, with a record-date of May 9, 2025. Treasury shares are not entitled to dividend distributions.

B.    Significant Changes
Change in operating segments.

In its annual report for the year ended December 31, 2023, the company reported its results in three operating segments: Steel, Mining and Usiminas. This was the result of the consolidation of Usiminas beginning in July 2023. As of March 31, 2024, following the acquisition of an additional participation in Usiminas on July 3, 2023, the Chief Operating Decision Maker performed a review of the new business structure to decide on the allocation of resources and the assessment of performance, and decided to organize the Company in two operating segments: Steel and Mining. For additional information see note 5 to the consolidated financial statements included in this annual report.

General
 
The following is a summary of certain rights of holders of Ternium S.A.’s shares. These rights are set out in the articles of association or are provided by applicable Luxembourg law, and may differ from those typically provided to shareholders of U.S. companies under the corporation laws of some states of the United States. This summary is not exhaustive and does not contain all information that may be important to you. For more complete information, you should read the articles of association, which are attached as an exhibit to this annual report.
 
Ternium S.A. is a société anonyme organized under the laws of Luxembourg, registered under the number B98 668 in the Luxembourg Registre de Commerce et des Sociétés. Its object and purpose, as set forth in Article 2 of its articles of association, is the taking of interests, in any form, in corporations or other business entities, and the administration, management, control and development thereof.
 
Ternium S.A.’s authorized share capital is fixed by the articles of association, as amended from time to time, with the approval of shareholders at an extraordinary general shareholders’ meeting. Ternium S.A. has an authorized share capital of a single class of 3,500,000,000 shares having a nominal value of $1.00 per share.
117


There were 2,004,743,442 shares issued as of the date of this annual report (including treasury shares). All issued shares are fully paid.
 
Ternium S.A.’s articles of association authorize the board of directors, or any delegate(s) duly appointed by the board of directors, to issue shares within the limits of its authorized share capital against contributions in cash, contributions in kind or by way of incorporation of available reserves, at such times and on such terms and conditions, including the issue price, as the board of directors, or its delegate(s) may in its or their discretion resolve.

The extraordinary shareholders meeting held on June 5, 2020 approved the renewal for an additional five-year period of the authorization granted to the board of directors to waive, suppress or limit any preemptive subscription rights of shareholders provided for by law to the extent it deems such waiver, suppression or limitation advisable for any issue or issues of shares within the authorized share capital; and have waived any preemptive subscription rights provided for by law and related procedures. The authorization period will expire on June 19, 2025, and a renewal of this authorization for an additional five-year period will be proposed at the extraordinary shareholders' meeting scheduled to be held on May 6, 2025. However, under the articles of association, for as long as Ternium S.A.’s shares are listed on a regulated market (and only for as long as they are so listed), any issuance of shares for cash within the limits of the authorized share capital shall be subject to the preemptive subscription rights of the then existing shareholders, except in the following cases (in which cases no preemptive rights shall apply):
 
(a) any issuance of shares for, within, in conjunction with or related to, an initial public offering of Ternium S.A.’s shares on one or more regulated markets (in one or more instances);

(b) any issuance of shares against a contribution other than in cash;

(c) any issuance of shares upon conversion of convertible bonds or other instruments convertible into Ternium S.A.’s shares; provided, however, that the preemptive subscription rights of the then existing shareholders shall apply by provision of the articles of association in connection with any issuance of convertible bonds or other instruments convertible into shares for cash; and

(d) any issuance of shares (including by way of free shares or at a discount), up to an amount of 1.5% of Ternium S.A.’s issued share capital, to directors, officers, agents or employees, its direct or indirect subsidiaries, or its affiliates, including without limitation the direct issue of shares upon the exercise of options, rights convertible into shares, or similar instruments convertible or exchangeable into shares issued for the purpose of, or in relation to, compensation or incentive for any such persons or in relation thereto (which the board of directors shall be authorized to issue upon such terms and conditions as it deems fit).

Amendment of the articles of association requires the approval of shareholders at an extraordinary shareholders’ meeting with a two-thirds majority vote of the shares represented at the meeting.

Dividends
 
Subject to applicable law, all shares (including shares underlying ADSs) are entitled to participate equally in dividends when, as and if declared by the shareholders at the annual general shareholders’ meeting, out of funds legally available for such purposes. Treasury shares are not entitled to dividend distributions.

Dividends may be lawfully declared and paid if net profits and distributable reserves are sufficient under Luxembourg law. The amount and payment of dividends must be approved by a majority vote at a general shareholders’ meeting, generally, but not necessarily, based on the recommendation of the board of directors. Under Article 21 of the articles of association, the board of directors has the power to distribute interim dividends out of profits, share premium or any other available reserves, in accordance with applicable law, in particular in accordance with the conditions set forth in article 461-3 of the Luxembourg Company Law. Such dividend payments must be finally approved by the general shareholders’ meeting. On March 21, 2025, the board of directors announced the proposals to be submitted to the consideration of the annual general shareholders’ meeting scheduled to be held on May 6, 2025, including its proposal on dividends.

As provided by Article 21 of the articles of association, dividends or other distributions declared by the general meeting as well as interim dividends or other distributions declared by the board of directors will be distributed at the times and places determined by the board of directors. Ternium S.A.
118


will make any and all dividend payments and any other distributions in respect of shares registered in the name of any securities settlement system or operator of such a system or in the name of any financial institution or other professional depositary of securities or any other depositary, whether in cash, shares or other assets, only to such registered holder, or otherwise in accordance with such registered holder’s instructions, and, as provided by Article 21 of the articles of association, that payment shall release Ternium S.A. from any and all obligations for such payment.

Ternium S.A. conducts and will continue to conduct its operations through subsidiaries and, accordingly, its main source of cash to pay dividends among other possible sources, will be the dividends received from its subsidiaries. For further information, see Item 3. “Key Information—D. Risk Factors—Risks Relating to the Structure of the Company—Ternium S.A.’s dividend payments depend on the results of operations and financial condition of its subsidiaries and could be affected by legal, contractual or other limitations or tax changes”. Dividend payments will depend on Ternium S.A.’s subsidiaries’ results of operations, financial condition, cash and capital requirements, future growth prospects and other factors deemed significant by their respective boards of directors, as well as on any applicable legal restrictions. For further information, see Item 3. “Key Information—D. Risk Factors—Risks Relating to the Countries in Which Ternium Operates—Argentina”.

Under Luxembourg law, claims for dividends will lapse in favor of Ternium S.A. five years after the date such dividends are declared. However, Ternium S.A. may elect to pay a declared dividend after such period. Declared and unpaid dividends held by Ternium S.A. for the account of its shareholders do not bear interest.

Pursuant to Luxembourg law, at least 5% of our net profits per year must be allocated to the creation of a legal reserve until such reserve has reached an amount equal to 10% of our issued share capital. If the legal reserve later falls below the 10% threshold, at least 5% (or such lower amount required to reach the 10% threshold) of net profits again must be allocated toward the reserve. As of December 31, 2024, Ternium S.A.’s legal reserve represented 10% of its share capital. The legal reserve is not available for distribution.
 
Voting Rights; Shareholders’ Meetings; Election of Directors
 
Each share entitles the holder thereof to one vote at the general shareholders’ meetings. Shareholder action by written consent is not permitted, but proxy voting is permitted. Notices of general shareholders’ meetings are governed by the provisions of Luxembourg law and the articles of association. Pursuant to applicable Luxembourg law, Ternium S.A. must give notice of the calling of any general shareholders meeting at least 15 days prior to the date for which the meeting is being called, by publishing the relevant convening notice in the Recueil électronique des sociétés et associations (Luxembourg's electronic official gazette) and in a leading newspaper having general circulation in Luxembourg and by issuing a press release informing of the calling of such meeting. The articles of association provide that notices for any general shareholders’ meeting shall include such information and shall be given in such form through such means and at such time or times as may be required under applicable Luxembourg law; and, in case Ternium S.A.’s shares are listed on a regulated market, such notices shall, in addition, satisfy such requirements as are applicable to, and mandatory for, notices of general shareholders’ meetings of issuers such as Ternium S.A. under the applicable laws, rules and regulations of such regulated market.

No attendance quorum is required at ordinary general shareholders’ meetings and resolutions may be adopted by a simple majority vote of the shares present or represented and voted at the meeting. An extraordinary general shareholders’ meeting may only validly deliberate when at least half of the share capital is present or represented. If the required quorum is not met at an extraordinary general shareholders meeting, a second meeting may be convened in accordance with the articles of association and applicable law and such second extraordinary general shareholders meeting shall validly deliberate regardless of the quorum present or represented. Resolutions on the following matters may only be adopted at extraordinary general shareholders’ meetings: (a) amendment to the articles of association; (b) dissolution and liquidation; (c) setting of the authorized share capital and granting of authorization to the board of directors to increase the share capital within the limits of the authorization; (d) decrease of the share capital; and (e) sale of all or substantially all of the assets. Such resolutions, in order to be adopted, must be approved by a majority of at least two-thirds of the votes of the shares present or represented. The following matters shall require a unanimous resolution of all the shareholders of Ternium S.A.: (a) change of the nationality of Ternium S.A.; and (b) increase of shareholders’ commitments.

Cumulative voting is not permitted. The articles of association do not provide for staggered terms, and directors are elected for a maximum of one year but may be reappointed or removed at any time, with or without cause, by the general shareholders’ meeting, by resolution passed by a simple majority vote of the shares present or represented at the meeting and voted. In the case of a vacancy occurring on the board of directors, the remaining directors shall have the right to temporarily fill such vacancy with a temporary director appointed by resolution adopted with the affirmative vote of a majority of the remaining directors; provided that the next general shareholder’s meeting shall be called upon to ratify such appointment.
119


The term of a temporary director elected to fill a vacancy shall expire at the end of the term of office of the replaced director.
 
The next annual general meeting of shareholders that will consider, among other matters, the 2024 consolidated financial statements and annual accounts, is scheduled to be held on May 6, 2025 at 9:00 a.m. (Central European Time) at the Ternium S.A.’s registered office in Luxembourg.

The articles of association provide that annual general shareholders’ meetings shall meet in Luxembourg within six months from the end of the previous financial year at the date, place and hour indicated in the convening notice.
 
Any shareholder who holds one or more shares of Ternium S.A. on the fifth calendar day preceding a general shareholders’ meeting (the “Record Date”) shall be admitted to such general shareholders’ meeting. Those shareholders who have sold their shares between the Record Date and the date of the general shareholders’ meeting may not attend or be represented at the meeting.
 
In the case of shares held through fungible securities accounts, each shareholder may exercise all rights attached to his shares and, in particular, may participate in and vote at shareholders’ meetings upon presentation of a certificate issued by the financial institution or professional depositary holding the shares, evidencing such deposit and certifying the number of shares recorded in the relevant account on the Record Date. Such certificate must be filed at least five days before the meeting at Ternium S.A.’s registered address or at the address stated in the convening notice or, in case the Ternium S.A.’s shares are listed on a regulated market, with an agent located in the country of the listing and designated in the convening notice. In case any such holder wishes to vote by proxy, the holder shall have to present a completed proxy form together with the certificate previously referred to, by the same date and time and at the same addresses. The board of directors and the shareholders at the shareholders’ meeting may, if they deem so advisable, reduce these periods of time for all shareholders and admit all shareholders (or their proxies) who have filed the appropriate documents to the general shareholders’ meeting, irrespective of these time limits.

Holders of ADSs only have those rights that are expressly granted to them in the deposit agreement dated January 31, 2006 among Ternium S.A., The BNY Mellon, as depositary (the "Depositary"), and the owners and beneficial owners from time to time of its ADSs. See Item 3.D. “Key Information – Risk Factors – Risks Relating to Ternium S.A.’s ADSs – Holders of ADSs may not be able to exercise, or may encounter difficulties in the exercise of, certain rights afforded to shareholders”. ADS holders may not attend or directly exercise voting rights in shareholders’ meetings, but holders of record of our ADSs as of the relevant ADS holders’ record date set for any given general shareholders’ meeting are entitled to instruct the Depositary as to the exercise of the voting rights in respect of the shares underlying such holder’s ADSs at such meeting.
 
Access to Corporate Records
 
Luxembourg law and the articles of association do not generally provide for shareholder access to corporate records. Shareholders may inspect the annual accounts and auditors’ reports at the company’s website https://investors.ternium.com or at its registered office starting from the call to the annual general shareholder’s meeting.
 
Appraisal Rights
 
In case the shares of Ternium S.A. are listed on one or more regulated markets, and in the event the shareholders, in a general meeting, approve any of the following:
 
•the delisting of Ternium S.A.’s shares from all regulated markets where the shares are listed at that time, excluding a delisting made pursuant to an offer to all of Ternium S.A.’s shareholders made by a business entity subject to common control with Ternium S.A., whereby such business entity offers to issue, in exchange for Ternium S.A.’s shares, shares to be listed on the same regulated market(s) on which Ternium S.A.’s shares are listed;

•a merger in which Ternium S.A. is not the surviving entity (unless the shares or other equity securities of such entity are listed on the New York or London stock exchanges);

•a sale, lease, exchange or other disposition of all or substantially all of Ternium S.A.’s assets;

•an amendment to the articles of association that has the effect of materially changing its corporate purpose;

120


•the relocation of Ternium S.A.’s domicile outside the Grand Duchy of Luxembourg; or

•amendments to the articles of association that restrict the rights of its shareholders (excluding any amendments in relation with, or to, the authorized share capital and/or the waiver or suppression of any preferential subscription rights relating thereto).

Dissenting or absent shareholders have the right to have their shares repurchased by Ternium S.A. at (i) the average market value of the shares over the 90 calendar days preceding the applicable general shareholders’ meeting or (ii) in the event that Ternium S.A.’s shares are not traded on any regulated market, the amount that results from applying the proportion of the equity that the shares being sold represent over the net worth as determined in its last consolidated financial statements approved by the shareholders or in its last interim consolidated financial statements approved by the board of directors, whichever is more recent. Shareholders who voted in favor of the relevant resolution are not entitled to exercise this right.
 
Dissenting or absent shareholders must present their claim within one month following the date of the applicable general shareholders’ meeting and supply Ternium S.A. with evidence of their shareholding at the time of such meeting. Ternium S.A. must (to the extent permitted by applicable laws and regulations and in compliance therewith) repurchase its shares within six months following the date of the applicable general shareholders’ meeting. If delisting from one or more, but not all, of the regulated markets where Ternium S.A.’s shares are listed is approved by the shareholders’ meeting, only dissenting or absent shareholders with shares held through participants in the local clearing system for that market or those markets can exercise this appraisal right if:
 
•they held the shares as of the date of the announcement of Ternium S.A.’s intention to delist or as of the date of publication of the first convening notice for the general shareholders’ meeting that approved the delisting;

•they present their claim within one month following the date of the general shareholders’ meeting and supply evidence of their shareholding as of the date of Ternium S.A.’s announcement or the publication of the first convening notice to the meeting; and

•the delisting is not being made pursuant to an offer to all of Ternium S.A.’s shareholders made by a business entity subject to common control with Ternium S.A., whereby such business entity offers to issue, in exchange for Ternium S.A.’s shares, shares to be listed on the same regulated market(s) on which such dissenting or absent shareholders hold their shares through participants in the local clearing system for that market or markets.

In the event a shareholder exercises its appraisal rights, applicable Luxembourg law provisions shall apply. Holders of ADSs may not be able to exercise, or may encounter difficulties in the exercise of, certain rights afforded to shareholders, including appraisal rights. See Item 3.D. “Key Information – Risk Factors – Risks Relating to the Company's ADSs – Holders of ADSs may not be able to exercise, or may encounter difficulties in the exercise of, certain rights afforded to shareholders”.
 
Distribution of Assets on Winding-up
 
In the event of liquidation, dissolution or winding-up, the net assets remaining after allowing for the payment of all debts, charges and expenses shall be paid out to holders of the company’s shares in proportion to their respective holdings.
 
Transferability and Form
 
Ternium S.A.’s articles of association do not contain any redemption or sinking fund provisions, nor do they impose any restrictions on the transfer of shares. The shares are issuable in registered form only.
 
The ownership of registered shares is evidenced by the inscription of the name of the shareholder, the number of shares held by such shareholder and the amount paid on each share in the share register. In addition, Ternium S.A.’s shares may be held through fungible securities accounts with financial institutions or other professional depositaries. Shares held through fungible securities accounts have the same rights and obligations as shares recorded in the shareholders’ register.
 
Shares held through fungible securities accounts may be transferred in accordance with customary procedures for the transfer of securities in book-entry form. Shares that are not held through fungible securities accounts may be transferred by a written statement of transfer signed by both the transferor and the transferee or their respective duly appointed attorney-in-fact and recorded in the share register.
121


The transfer of shares may also be made in accordance with the provisions of Article 1690 of the Luxembourg Civil Code. As evidence of the transfer of registered shares, Ternium S.A. may also accept any correspondence or other documents evidencing the agreement between transferor and transferee as to the transfer of registered shares.
 
Repurchase of Shares
 
Ternium S.A. may repurchase its own shares in the cases and subject to the conditions set by the Luxembourg Company Law and, in the case of acquisitions of shares or ADSs made through NYSE, with any applicable laws and regulations of such market. See Item 16.E. “Purchases of Equity Securities by the Issuer and Affiliated Purchasers” for further information on the authorization to Ternium S.A. or its subsidiaries to repurchase Ternium S.A.’s shares, including shares represented by ADSs.
 
Limitation on Securities Ownership
 
There are no limitations currently imposed by Luxembourg law or the articles of association on the rights of Ternium S.A.’s non-resident or foreign shareholders to hold or vote Ternium S.A.’s shares.

Change in Control
 
None of our outstanding securities has any special control rights. The articles of association do not contain any provision that would have the effect of delaying, deferring or preventing a change in control of Ternium S.A. and that would operate only with respect to a merger, acquisition or corporate restructuring involving Ternium S.A. or any of its subsidiaries. In addition, the company does not know of any significant agreements or other arrangements to which the company is a party and which take effect, alter or terminate in the event of a change of control of Ternium S.A. There are no agreements between Ternium S.A. and members of its board of directors or employees providing for compensation if they resign or are made redundant without reason, or if their employment ceases following a change in control of Ternium S.A.

There are no rights associated with Ternium S.A.’s shares other than those described above.
 
C.     Material Contracts
 
For a summary of any material contract entered into by us outside of the ordinary course of business during the last two years, see Item 4. “Information on the Company—B. Business Overview—Raw Materials, Slabs, Energy and Other Inputs.”
 
D.     Exchange Controls
 
Many of the countries which are important markets for us or in which we have substantial assets have a history of substantial government intervention in currency markets, volatile exchange rates and government-imposed currency controls. These include Mexico, Brazil and Argentina. For additional information regarding Ternium’s ability to hedge against exchange rate fluctuations, see Item 3. “Key Information—D. Risk Factors—Risks Relating to Ternium's Business—Changes in exchange rates or any limitation in the ability of the Ternium companies to hedge against exchange rate fluctuations could adversely affect Ternium’s business and results.”

Mexico
 
Historically, the Mexican economy has suffered balance of payment deficits and shortages in foreign exchange reserves. While the Mexican government does not currently restrict the ability of Mexican or foreign persons or entities to convert Mexican pesos to U.S. dollars and the terms of USMCA—to which Mexico is a signatory—generally prohibit exchange controls, the Mexican government could institute a restrictive exchange control policy in the future.

Brazil
 
While currently there are no significant exchange controls in Brazil, in the past, the Brazilian central bank has intervened occasionally to control unstable movements in foreign exchange rates including through the introduction of different exchange markets.
122


We cannot predict whether the central bank or the Brazilian government will continue to let the real float freely or will intervene in the exchange rate market through the return of a currency band system or otherwise. Furthermore, the real may depreciate or appreciate against the U.S. dollar and this may have an impact on our operations (see Item 11. Quantitative and Qualitative Disclosures About Market Risk—Foreign Exchange Exposure Risk.)

Argentina
 
From time to time, the Argentine authorities have taken measures to reduce the volatility of the ARS/$ exchange rate and have implemented formal and informal restrictions on capital inflows and outflows.

Between September 2019 and December 2023, the Argentine government imposed significant restrictions on foreign exchange transactions; however, the current administration in Argentina eased certain restrictions since taking office and other changes to such regulations are expected. At the date of this annual report, the scope and timing of upcoming changes remain unknown. Currently, Argentine companies are required to repatriate export proceeds from sales of goods and services (including U.S. dollars obtained through advance payment and pre-financing facilities) and convert such proceeds into ARS at the official exchange rate. Since December 13, 2023, up to 20% of export proceeds can be sold for Argentine pesos through securities transactions resulting in a higher implicit exchange rate as explained below. This percentage has changed and is expected to change over time. Import payments for services rendered and goods no longer require government approval but cannot be paid in advance or at sight and are subject to a minimum 30-day deferred payment. In addition, until January 1, 2025, import payments were subject to import taxes that significantly increased prices of imported goods and services. Argentine companies must still obtain prior Argentine Central Bank authorization, which is rarely (if ever) granted, to access the foreign exchange market to make dividend payments.

Furthermore, foreign exchange controls in Argentina limiting the purchase and transfer abroad of foreign currency for saving purposes, restrict Ternium Argentina’s ability to hold excess cash reserves in foreign bank accounts. The existing measures substantially limit the ability of Argentine companies to obtain foreign currency and make certain payments and distributions out of Argentina at the official exchange rate.

For more information on our foreign exchange restrictions in Argentina, see note 30 “Foreign exchange restrictions in Argentina” to our consolidated financial statements included in this annual report.

Regulations or restrictions imposed by the former government administration as well as new regulations enacted by the current administration, may restrict Ternium Argentina’s ability to access the official foreign exchange market, expose Ternium to the risk of losses arising from fluctuations in the ARS/$ exchange rate, or impair Ternium Argentina’s ability to make payments abroad (including dividends or royalties), or fund investments or other activities offshore.

For additional information regarding factors affecting the Argentine economy, see Item 3. “Key Information—D. Risk Factors—Risks Relating to the Countries in Which Ternium Operates—Argentina.”; for additional information on current foreign exchange restrictions in Argentina, see note 30 “Foreign exchange restrictions in Argentina” to our consolidated financial statements included in this annual report.

Colombia
 
Under Colombian foreign exchange regulations, payments in foreign currency related to certain foreign exchange transactions must be conducted through the commercial exchange market, by means of an authorized financial intermediary, and the payment must be declared to the Colombian central bank. This mechanism applies to payments in connection with, among others, imports and exports of goods, foreign loans and related financing costs, investment of foreign capital and the remittances of profits thereon, investment in foreign securities and assets and endorsements and guarantees in foreign currency. Transactions through the commercial exchange market are made at market rates freely negotiated with the authorized intermediaries.
 
E.     Taxation
 
The following discussion of the material Luxembourg and U.S. federal income tax consequences of an investment in our shares and ADSs is based upon laws and relevant interpretations thereof in effect as of the date of this annual report, all of which are subject to change. This discussion does not address all possible tax consequences relating to an investment in our shares or ADSs, including the tax consequences under U.S. state and local tax laws.

 Grand Duchy of Luxembourg
 
This section describes the material Luxembourg tax consequences of owning or disposing of shares or ADSs.
It is not intended to be, nor should it be construed to be, legal or tax advice. You should, therefore, consult your own tax advisor regarding local or foreign tax consequences, including Luxembourg tax consequences of owning and disposing of shares or ADSs in your particular circumstances.
As used herein, a “Luxembourg individual” means an individual resident in Luxembourg who is subject to personal income tax (impôt sur le revenu) on his or her worldwide income from Luxembourg or foreign sources, and a “Luxembourg corporate holder” means a company (that is, a fully taxable collectivité within the meaning of Article 159 of the Luxembourg Income Tax Law) resident in Luxembourg subject to Luxembourg corporate income tax (impôt sur le revenu des collectivités) and Luxembourg municipal business tax (impôt commercial communal, on its worldwide income from Luxembourg or foreign sources). For the purposes of this summary, Luxembourg individuals and Luxembourg corporate holders are collectively referred to as “Luxembourg Holders”. A “non-Luxembourg Holder” means any investor in shares or ADSs of Ternium S.A. other than a Luxembourg Holder.
Corporate Reorganization
 
Ternium S.A. was established as a Luxembourg société anonyme holding under Luxembourg’s 1929 holding company regime. Until termination of such regime on December 31, 2010, holding companies incorporated under the 1929 regime (including Ternium S.A.) were exempt from Luxembourg corporate income tax, Luxembourg municipal business tax, Luxembourg net wealth tax and Luxembourg withholding tax over dividends distributed to shareholders.

On January 1, 2011, Ternium S.A. became an ordinary public limited liability company (société anonyme) and, effective as from that date, it is subject to all applicable Luxembourg taxes (including, among others, Luxembourg corporate income tax on its worldwide income).

In light of the impending termination of Luxembourg’s 1929 holding company regime, in the fourth quarter of 2010, Ternium S.A. carried out a multi-step corporate reorganization, which included, among other transactions, the contribution of most of its assets and liabilities to a wholly-owned, newly-incorporated Luxembourg subsidiary, and the restructuring of indirect holdings in certain subsidiaries.

The first phase of the corporate reorganization was completed in December 2010 and resulted in a non-taxable revaluation of the accounting value (under Luxembourg GAAP) of Ternium S.A.’s assets. The second phase of the reorganization was completed in 2011.

Following the completion of the first phase of the corporate reorganization, and upon its conversion into an ordinary Luxembourg holding company, Ternium S.A. recorded a special reserve in its tax balance sheet for an amount of $7.9 billion ($1.7 billion remaining at 2024 year-end). Dividend distributions will be charged to the special reserve and therefore should not be subject to Luxembourg withholding tax (up-to- the remaining amount of such special reserve).

Tax regime applicable to realized capital gains
 
Luxembourg Holders
 
Luxembourg resident individual holders
 
Capital gains realized by Luxembourg resident individuals who do not hold their shares or ADSs as part of a trade or business (i.e. capital gains on private assets) and who hold (together, directly or indirectly, with their spouse or civil partner and underage children) no more than 10% of Ternium S.A.’s share capital at any time during the five-year period preceding the disposition will only be taxable (at a progressive rate) if they are realized on a sale of shares or ADSs that takes place before their acquisition or within the first six months following their acquisition (i.e. speculative gain). After the six-months period, capital gains are not taxed unless the resident individual holds (together, directly or indirectly, with his or her spouse or civil partner and underage children) more than 10% of Ternium S.A.’s share capital at any time during the five-year period preceding the disposition.

If such shares or ADSs are held as part of a commercial or industrial business, capital gains would be taxable in the same manner as income from such business.
124



Capital gains realized by Luxembourg resident individuals holding (alone or together with the resident’s spouse or civil partner and underage children) directly or indirectly more than 10% of Ternium S.A.’s capital at any time during the five years prior to the sale, (or if the Luxembourg resident individuals have received the shares for no consideration within the last five years and the former holder held at least 10% in Ternium S.A.’s capital at any moment during said five years) will be taxable at half of the individual’s applicable global tax rate (as determined progressively), if a holding period of six months following their acquisition elapsed (21% for 2024). Within the six month period, progressive income tax rates apply (ranging from 0 to 42%* in 2024).

*A 7% surcharge for the Employment Fund applies on the income tax due. The surcharge for the Employment Fund amounts to 9% for taxpayer in tax class 1 or 1a with taxable income exceeding EUR 150,000 (EUR 300,000 for taxpayer in tax class 2).

Luxembourg resident corporate holders
 
Capital gains, including currency exchange gains realized upon the disposal of shares or ADSs by a fully taxable resident corporate holder, will in principle be subject to Luxembourg corporate income tax and Luxembourg municipal business tax. The combined applicable rate (including an unemployment fund contribution) for a corporate holder established in Luxembourg City is 24.94% for the fiscal year ending 2024. An exemption from such taxes may be available to the Luxembourg resident corporate holder pursuant to Article 1 of the Grand Ducal Decree dated December 21, 2001 as amended, in combination with article 166 of the Luxembourg Income Tax Law subject to the fulfillment of the conditions set forth therein.
 
Non-Luxembourg Holders

Non-Luxembourg individual holders
An individual who is a non-Luxembourg Holder of shares or ADSs (and who does not have a permanent establishment, a permanent representative or a fixed place of business in Luxembourg) will only be subject to Luxembourg taxation on capital gains arising upon disposal of such shares or ADSs if such holder has (alone or together with his or her spouse, civil partner and underage children) directly or indirectly held more than 10% of Ternium S.A.’s capital at any time during the past five years preceding the disposal, and either (i) such non-Luxembourg Holder has been a resident of Luxembourg for tax purposes for at least 15 years and has become a non-resident within the last five years preceding the realization of the gain, subject to any applicable tax treaty, or (ii) the disposal of shares or ADSs occurs within six months from their acquisition (or prior to their actual acquisition), subject, however, to any applicable tax treaty.

Non-Luxembourg corporate holders
A corporate non-Luxembourg Holder (that is, a collectivité within the meaning of Article 159 of the Luxembourg Income Tax Law), which has a permanent establishment, a permanent representative or a fixed place of business in Luxembourg to which shares or ADSs are attributable, will bear Luxembourg corporate income tax and Luxembourg municipal business tax on a gain realized on a disposal of such shares or ADSs as set forth above for a Luxembourg corporate holder. However, capital gains, including currency exchange gains, realized on the sale of the shares or ADSs may benefit from the full exemption provided for by Article 1 of the Grand Ducal Decree dated December 21, 2001, as amended, in combination with Article 166 of the Luxembourg Income Tax Law subject in each case to fulfillment of the conditions set out therein.

A corporate non-Luxembourg Holder, which has no permanent establishment, permanent representative or fixed place of business in Luxembourg to which the shares or ADSs are attributable, will bear non-resident capital gains tax on a gain realized on a disposal of such shares or ADSs under the same conditions applicable to an individual non-Luxembourg Holder, as set out above.
 
125


Tax regime applicable to distributions
 
Withholding tax
 
Distributions to holders are in principle subject to a 15% Luxembourg withholding tax computed on the gross amount distributed. The rate of the withholding tax may be reduced pursuant to a double tax treaty existing between Luxembourg and the country of residence of the relevant holder, subject to the fulfillment of the conditions set forth therein. However, distributions imputed for tax purposes to the special reserve (please see above paragraph “Corporate Reorganization”) should be exempt from Luxembourg withholding tax under the current tax law.

Nevertheless, a withholding tax exemption may apply if the distribution is made to (as far as relevant in the case at hand):

•a Luxembourg resident corporate holder (that is, a fully taxable collectivité within the meaning of article 159 of the Luxembourg Income Tax Law);
•the Luxembourg State, a municipality, or a public body;
•an undertaking of collective character which is resident of a Member State of the European Union and is referred to by article 2 of the EU Council Directive of November 30, 2011 concerning the common fiscal regime applicable to parent and subsidiary companies of different member states (2011/96/UE) as amended, (subject to the general anti-abuse rule provided for by Council Directive 2015/121/EU as implemented into Luxembourg law);
•a capital company or a cooperative company resident in Norway, Iceland or Liechtenstein and subject to a tax comparable to corporate income tax as provided by the Luxembourg Income Tax Law;
•a Luxembourg permanent establishment of one of the above-mentioned categories;
•a capital company resident in Switzerland which is subject to corporate income tax in Switzerland without benefiting from an exemption; and
•an undertaking with a collective character subject to a tax comparable to corporate income tax as provided by the Luxembourg Income Tax Law which is resident in a country that has concluded a double tax treaty with Luxembourg.

provided each time that at the date of payment, the holder holds or commits to hold directly (or through a company regarded as tax transparent from a Luxembourg tax perspective), during an uninterrupted period of at least twelve months, shares or ADSs representing at least 10% of Ternium S.A.’s share capital or acquired for an acquisition price of at least EUR 1,200,000.
 
Luxembourg Holders
 
With the exception of Luxembourg corporate holders benefiting from the application of Luxembourg participation exemption as per Article 166 of Luxembourg Income Tax Law (provided that the relevant requirements are met), Luxembourg individual holders, and Luxembourg corporate holders fully subject to Luxembourg corporate tax, must include the distributions received on the shares or ADSs in their taxable income, 50% of the amount of such dividends being exempt from tax. The applicable withholding tax can, under certain conditions, entitle the relevant Luxembourg Holder to a tax credit.

Non Luxembourg Holders

Non-Luxembourg Holders of shares or ADSs and who do not have a permanent establishment, a permanent representative or a fixed place of business in Luxembourg to which the shares or ADSs would be attributable are not liable for any Luxembourg tax on dividends received on the shares or ADSs, other than a potential withholding tax as described above.

Net wealth tax
 
Luxembourg Holders
 
Luxembourg net wealth tax will not be levied on a Luxembourg Holder with respect to the shares or ADSs held unless (i) the Luxembourg Holder is a legal entity subject to net wealth tax in Luxembourg; or (ii) the shares or ADSs are attributable to an enterprise or part thereof which is carried on through a permanent establishment, a fixed place of business or a permanent representative in Luxembourg.

126


Net wealth tax is levied annually at the rate of 0.5% for taxable net wealth not exceeding EUR 500,000,000 and at a rate of 0.05% for the net wealth exceeding EUR 500,000,000, of enterprises resident in Luxembourg, as determined for net wealth tax purposes. The shares or ADSs may be exempt from net wealth tax subject to the conditions set forth by Paragraph 60 of the Luxembourg Law of October 16, 1934 on the valuation of assets (Bewertungsgesetz), as amended.

A minimum net wealth tax charge applies as of January 1, 2016 for all corporate entities having their statutory seat or central administration in Luxembourg. Subject to certain conditions, the amount of minimum net wealth tax may vary.
 
Non-Luxembourg Holders
 
Luxembourg net wealth tax will not be levied on a non-Luxembourg Holder with respect to the shares or ADSs held unless the shares or ADSs are attributable to an enterprise or part thereof which is carried on through a permanent establishment or a permanent representative in Luxembourg. The shares or ADSs may be exempt from net wealth tax subject to the conditions set forth by Paragraph 60 of the Luxembourg Law of October 16, 1934 on the valuation of assets (Bewertungsgesetz), as amended.

Stamp and registration taxes
 
No registration tax or stamp duty will be payable by a holder of shares or ADSs in Luxembourg solely upon the disposal of shares or ADSs by sale or exchange.
 
Estate and gift taxes
 
No estate or inheritance tax is levied on the transfer of shares or ADSs upon the death of a holder of shares or ADSs in cases where the deceased was not a resident of Luxembourg for inheritance tax purposes and no gift tax is levied upon a gift of shares or ADSs if the gift is not passed before a Luxembourg notary or recorded in a deed registered in Luxembourg.

Where a holder of shares or ADSs is a resident of Luxembourg for tax purposes at the time of the holder's death, the shares or ADSs are included in its taxable estate for inheritance tax or estate tax purposes.
 
U.S. federal income taxation
 
This section describes the material U.S. federal income tax consequences to a U.S. holder (as defined below) of owning shares or ADSs. It applies to you only if you hold your shares or ADSs as capital assets for U.S. federal income tax purposes. This discussion addresses only U.S. federal income taxation and does not discuss all of the tax consequences that may be relevant to you in light of your individual circumstances, including foreign, state or local tax consequences, estate and gift tax consequences, and tax consequences arising under the Medicare contribution tax on net investment income or the alternative minimum tax. This section does not apply to you if you are a member of a special class of holders subject to special rules, including:
 
•a dealer in securities,
•a bank,
•a trader in securities that elects to use a mark-to-market method of accounting for securities holdings,
•a tax-exempt organization,
•a person who invests through a pass-through entity, including a partnership,
•a life insurance company,
•a person that actually or constructively owns 10% or more of the combined voting power of our voting stock or of the total value of our stock (including ADSs),
•a person that holds shares or ADSs as part of a straddle or a hedging or conversion transaction for U.S. federal income tax purposes,
•a person that purchases or sells shares or ADSs as part of a wash sale for U.S. federal income tax purposes, or
•a person whose functional currency is not the U.S. dollar.

This section is based on the Internal Revenue Code of 1986, as amended, its legislative history, existing and proposed regulations, published rulings and court decisions, all as currently in effect, as well as on the Convention between the Government of the Grand Duchy of Luxembourg and the Government of the United States of America for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with respect to Taxes on Income and Capital (the “Treaty”).
127


These laws are subject to change, possibly on a retroactive basis. In addition, this section is based in part upon the assumption that each obligation in the ADS deposit agreement and any related agreement will be performed in accordance with its terms.
 
If an entity or arrangement that is treated as a partnership for U.S. federal income tax purposes holds the shares or ADSs, the U.S. federal income tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. Each such partner of a partnership that holds the shares or ADSs is urged to consult his, her or its own tax advisor.
 
You are a U.S. holder if you are a beneficial owner of shares or ADSs and you are, for U.S. federal income tax purposes:
 
•an individual citizen or resident of the United States,
•a domestic corporation (or an entity treated as a domestic corporation),
•an estate whose income is subject to U.S. federal income tax regardless of its source, or
•a trust if (i) a U.S. court can exercise primary supervision over the trust’s administration and one or more U.S. persons are authorized to control all substantial decisions of the trust or (ii) the trust has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

In general, and taking into account the earlier assumptions, for U.S. federal income tax purposes, if you hold ADSs, you will be treated as the owner of the shares represented by those ADSs. Exchanges of shares for ADSs, and ADSs for shares, generally will not be subject to U.S. federal income tax.

The tax treatment of your shares or ADSs will depend in part on whether or not we are classified as a passive foreign investment company (“PFIC”), for U.S. federal income tax purposes. Except as discussed below under ”PFIC Rules”, this discussion assumes that we are not classified as a PFIC for United States federal income tax purposes.

You should consult your own tax advisor regarding the U.S. federal, state and local and other tax consequences of owning and disposing of shares or ADSs in your particular circumstances.

Taxation of distributions

Under the U.S. federal income tax laws, if you are a U.S. holder, the gross amount of any distribution we pay out of our current or accumulated earnings and profits (as determined for U.S. federal income tax purposes), other than certain pro-rata distributions of our shares will be treated as a dividend that is subject to U.S. federal income taxation. If you are a non-corporate U.S. holder, dividends paid to you that constitute qualified dividend income will be taxable to you at the preferential rates applicable to long-term capital gains provided that you hold shares or ADSs for more than 60 days during the 121-day period beginning 60 days before the ex-dividend date and meet other holding period requirements. Dividends we pay with respect to the shares or ADSs generally will be qualified dividend income, provided that, in the year that you receive the dividend, we are eligible for the benefits of the Treaty. We believe that we are currently eligible for the benefits of the Treaty and therefore expect that dividends on the shares or ADSs will be qualified dividend income, but there can be no assurance that we will continue to be eligible for the benefits of the Treaty.
 
You must generally include any Luxembourg tax withheld from the dividend payment in this gross amount even though you do not in fact receive it. The dividend is taxable to you when you receive it, or, in the case of ADSs, when the depositary receives the dividend, actually or constructively. The dividend will not be eligible for the dividends-received deduction generally allowed to U.S. corporations in respect of dividends received from other U.S. corporations. Distributions in excess of current and accumulated earnings and profits, as determined for U.S. federal income tax purposes, will be treated as a non-taxable return of capital to the extent of your basis in the shares or ADSs and thereafter as capital gain. However, we do not expect to calculate earnings and profits in accordance with U.S. federal income tax principles. Therefore, you should expect that a distribution will generally be treated as a dividend (as discussed above).
 
Dividends will generally be income from sources outside the United States and generally will be “passive” income for purposes of computing the foreign tax credit allowable to you.
 
Subject to certain limitations, the Luxembourg tax withheld in accordance with the Treaty and paid over to Luxembourg will be creditable or deductible against your U.S. federal income tax liability. However, under recently finalized Treasury regulations, it is possible that taxes may not be creditable unless you are eligible for and elect to apply the benefits of the Treaty.
128


Special rules apply in determining the foreign tax credit limitation with respect to dividends that are subject to the preferential tax rates. To the extent a refund of the tax withheld is available to you under Luxembourg law or under the Treaty, the amount of tax withheld that is refundable will not be eligible for credit against your U.S. federal income tax liability.
 
In certain circumstances, if you have held ADSs for less than a specified minimum period during which you are not protected from risk of loss, or are obligated to make payments related to the dividends, you will not be allowed a foreign tax credit for foreign taxes imposed on dividends that we pay.
 
The rules governing the foreign tax credit are complex. You are urged to consult your tax advisors regarding the availability of the foreign tax credit under your particular circumstances.

Taxation of capital gains
 
If you are a U.S. holder and you sell or otherwise dispose of your shares or ADSs, you will recognize capital gain or loss for U.S. federal income tax purposes equal to the difference between the U.S. dollar value of the amount that you realize and your tax basis, determined in U.S. dollars, in your shares or ADSs. Capital gains of a non-corporate U.S. holder is generally taxed at preferential rates where the property is held for more than one year. The gain or loss will generally be income or loss from sources within the United States for foreign tax credit limitation purposes. The deductibility of capital losses is subject to limitations.
 
    Additional U.S. Federal Income Tax Considerations
 
PFIC Rules: Based on Ternium S.A.’s current and expected income and assets, we believe that the shares or ADSs should not currently be treated as stock of a PFIC for U.S. federal income tax purposes and we do not expect to become a PFIC in the foreseeable future. However this conclusion is a factual determination that is made annually and thus may be subject to change. It is therefore possible that we could become a PFIC in a future taxable year. If we were to be treated as a PFIC, gains realized on the sale or other disposition of your shares or ADSs would in general not be treated as capital gains. Furthermore, if you are a U.S. holder, unless you are permitted to elect and you do elect to be taxed annually on a mark-to-market basis with respect to the shares or ADSs, upon sale or disposition of shares or ADSs you would generally be treated as if you had realized such gain and certain “excess distributions” ratably over your holding period for the shares or ADSs and would be taxed at the highest tax rate in effect for each such year to which the gain was allocated, together with an interest charge in respect of the tax attributable to each such year. With certain exceptions, your shares or ADSs will be treated as stock in a PFIC if we were a PFIC at any time during your holding period in your shares or ADSs. Dividends that you receive from us will not be eligible for the special tax rates applicable to qualified dividend income if we are a PFIC (or are treated as a PFIC with respect to you) either in the taxable year of the distribution or the preceding taxable year, but instead will be taxable at rates applicable to ordinary income and subject to the excess distribution regime described above.

Item 11. Quantitative and Qualitative Disclosures About Market Risk
 
The multinational nature of our transactions, operations and customer base expose us to a variety of risks, including the effects of changes in interest rates, foreign currency exchange rates and commodity prices. We selectively manage these exposures through the use of derivative instruments to mitigate market risk and interest rate costs. In addition, we may use derivative instruments embedded in investment instruments, in compliance with Ternium’s policy for financial investments. We do not use derivative financial instruments for other purposes. In addition, in the ordinary course of business we also face risks with respect to financial instruments that are either non-financial or non-quantifiable. Such risks principally include country risk and credit risk and are not presented in the following analysis. For additional information about our financial risk management, see note 29 to the consolidated financial statements included in this annual report.
 
The following tables provide a breakdown of Ternium’s debt instruments as of December 31, 2024, by type of interest rate fixing mechanism and year of maturity. The following information should be read together with note 29 “Financial Risk Management” to the consolidated financial statements included in this annual report.

Foreign Exchange Exposure Risk
 
Ternium operates and sells its products in different countries, and as a result is exposed to foreign exchange rate volatility. Ternium’s subsidiaries may use derivative contracts in order to hedge their exposure to exchange rate risk derived from their trade and financial operations. A significant portion of Ternium’s business is carried out in currencies other than the U.S. dollar, Ternium’s reporting currency. As a result of this foreign currency exposure, exchange rate fluctuations impact Ternium’s results as reported in its income statement and statement of comprehensive income in the form of both translation and transaction risk. Translation risk is the risk that Ternium’s consolidated financial statements for a particular period or as of a certain date may be affected by changes in the prevailing rates of the various functional currencies of the reporting subsidiaries against the U.S. dollar. Transaction risk is the risk that the value of transactions executed in currencies other than the subsidiary’s functional currency may vary according to currency fluctuations.
 
Ternium’s foreign exchange policy seeks to minimize the impact of fluctuations in the value of other currencies with respect to the U.S. dollar, with the exception of the currencies of countries where it has operations in Latin America, in which Ternium may, from time to time, choose not to hedge operational short exposures to such currencies.
131


Ternium’s subsidiaries, with the exception of Usiminas, monitor their actual and expected short-term net cash flows in currencies other than the U.S. dollar and analyze potential hedging according to its needs in line with its derivative policy. Usiminas and its subsidiaries monitor their net operating cash flows in currencies other than the Brazilian real and analyse potential hedging strategies according to its exposure to the Brazilian real. This hedging can be carried out either by netting positions or by financial derivatives. However, regulatory or legal restrictions in the countries in which Ternium’s subsidiaries operate, could limit the possibility of the company carrying out its hedging policy.

U.S. dollar ($) (187)
E.U. euro (EUR) (5)
Other currencies (0)
The exposure sensitivities to the Mexican peso, Brazilian real, Colombian peso and Argentine peso are the following:

(a) Mexican peso vs. U.S. dollar. If the Mexican peso had weakened by 1% against the U.S. dollar, it would have generated a pre-tax gain of $8.0 million and $3.1 million as of December 31, 2024 and 2023, respectively.

(b) Brazilian real vs. U.S. dollar. If the Brazilian real had weakened by 1% against the U.S. dollar, it would have generated a pre-tax loss of $3.0 million and $5.3 million as of December 31, 2024 and 2023, respectively.

(c) Colombian peso vs. U.S. dollar. If the Colombian peso had weakened by 1% against the U.S. dollar, it would have generated a pre-tax gain of $0.6 million and $0.2 million as of December 31, 2024 and 2023, respectively.

(d) Argentine peso vs. U.S. dollar. If the Argentine peso had weakened by 1% against the U.S. dollar, it would have generated a pre-tax loss of $0.2 million and a pre-tax gain of $1.3 million as of December 31, 2024 and 2023, respectively.

We estimate that if the Mexican peso, the Brazilian real, the Colombian peso and the Argentine peso had weakened simultaneously by 1% against the U.S. dollar with all other variables held constant, total pre-tax gain for 2024 would have been $5.4 million higher, as a result of foreign exchange gains/losses on translation of U.S. dollar-denominated financial positions, local currency cash, trade receivables, trade payables, tax credits and liabilities, lease liabilities, borrowings and other liabilities.

Considering the same variation of the currencies against the U.S. dollar of all net investments in foreign operations amounting to $2.3 billion, the currency translation adjustment included in total equity would have been $5.2 million higher, arising mainly from the adjustment on translation of the equity related to the Brazilian real during the year 2024.
 
Foreign Exchange Contracts
 
During 2024, 2023 and 2022, Ternium Mexico entered into several forward agreements mainly to manage the exchange rate exposure generated by future payables in EUR related to the investment plan in Pesquería, Mexico, among other standard liabilities in EUR. The outstanding notional amount hedged as of December 31, 2024, was EUR570.3 million.
132


These agreements will be due up to December 2025 and have been accounted for as cash flow hedges. As of December 31, 2024, the aggregate notional amount on these agreements amounted to $617.4 million.

In addition, during 2024 Ternium Mexico entered into multiple non-deliverable forward agreements to manage the exposure arising from future payables in MXN linked to the investment plan in Pesquería, Mexico, seeking to mitigate the impact of exchange rate volatility on the budget assigned for the investment. These agreements will be settled in March 2026 and have been accounted for as cash flow hedges. As of December 31, 2024, their notional value amounted to $900.0 million.

Furthermore, during 2024 Ternium Mexico entered into non-deliverable forward agreements to manage the exchange rate exposure generated by future payables in JPY related to the investment plan in Pesquería, Mexico. The notional amount hedged as of December 31, 2024, was JPY1.8 billion. These agreements will be settled in May 2025, and have been accounted for as cash flow hedges. As of December 31, 2024, the notional amount on these agreements amounted to $11.8 million.

During 2024, 2023 and 2022, Ternium Colombia S.A.S. entered into non-deliverable forward agreements to manage the aggregate exposure arising from its balance sheet position in conjunction with expected future trade receivables denominated in its local currency. As of December 31, 2024, the notional amount on these agreements amounted to $30.0 million, which were settled on January 30 and 31, 2025.

During 2024 and 2023, Ternium Guatemala entered into several non-deliverable forward agreements in order to manage the exchange rate exposure generated primarily by trade receivables denominated in Guatemalan quetzals. As of December 31, 2024, the notional amount on these agreements amounted to $2.0 million, which were settled on January 27, 2025.

During 2024 and 2023, Ternium del Atlántico entered into several non-deliverable forward agreements to manage the aggregate exposure arising from its balance sheet position in conjunction with expected future trade receivables denominated in Colombian pesos. As of December 31, 2024, the notional amount on these agreements amounted to $38.0 million, which were settled on January 29 and 31, 2025.

During 2024 and 2023, Ternium Procurement entered into forward agreements in order to manage the exchange rate exposure generated by purchases of semi-finished steel products. As of December 31, 2024, the notional amount on these agreements amounted to $17.7 million, which were settled on February 14, 2025.

During 2024, Ternium Argentina conducted forward agreements as a strategy to convert financing rates in Argentine pesos to competitive $ rates through cross currency transactions, enhancing its overall financial costs. As of December 31, 2024, the notional amount on these agreements amounted to $37.8 million.

The consolidated net fair value of the exchange rate derivative contracts as of December 31, 2024, was negative $45.9 million. For further information on our foreign exchange contracts see note 22(b) to the consolidated financial statements included in this annual report.
 
Interest Rate Exposure Risk
 
Ternium manages its exposure to interest rate volatility through its financing alternatives and hedging instruments. Borrowings issued at variable rates expose the company to the risk of increased interest expense in the event of a raise in market interest rates, while borrowings issued at fixed rates expose the company to a variation in its fair value. The company’s interest-rate risk mainly arises from long-term borrowings that bear variable-rate interest that could be partially fixed through different derivative transactions, such as interest rate swaps.

Ternium’s nominal weighted average interest rate for its debt instruments, which do not include neither the effect of derivative financial instruments, nor the devaluation of the local currencies, was 8.83% and 8.46% as of December 31, 2024 and 2023, respectively. These rates were calculated using the rates set for each instrument in its corresponding currency and weighted using the dollar-equivalent outstanding principal amount of each instrument.

Ternium’s total variable interest rate debt amounted to $1,140.1 million (51% of total borrowings) as of December 31, 2024, and $1,065.9 million (50% of total borrowings) as of December 31, 2023. If interest rates on the aggregate average notional of U.S. dollar denominated borrowings held during 2024, excluding borrowings with derivatives contracts mentioned in note 22(a), had been 100 basis points higher with all other variables held constant, total pre-tax income for 2024 would have been $21.1 million lower ($18.3 million lower as of December 31, 2023).
133


 
Commodity Exposure Risk
 
During 2024, 2023 and 2022, Ternium Mexico entered into swap agreements to mitigate the impact of zinc price fluctuations affecting the manufacturing cost of galvanized products to be sold with a fixed zinc price. As of December 31, 2024, Ternium Mexico has several agreements outstanding with an aggregate notional amount of $9.0 million.

During 2024, 2023 and 2022, Mineração Usiminas, one of Usiminas’ subsidiaries, entered into forward agreements to manage the impact of the fluctuation of iron ore prices affecting its sales in the foreign market. As of December 31, 2024, Mineração Usiminas has several agreements outstanding with an aggregate notional amount of $61.5 million. These transactions are accounted for as cash flow hedges.

Item 15. Controls and Procedures
    Evaluation of Disclosure Controls and Procedures
 
Under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, we have evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act as of December 31, 2024). Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that, as of December 31, 2024, our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and to ensure that such information is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives. The Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures are effective at a reasonable assurance level.
 
Management’s Report on Internal Control over Financial Reporting
 
Management is responsible for establishing and maintaining adequate internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Our internal control over financial reporting was designed by management to provide reasonable assurance regarding the reliability of financial reporting and the preparation and fair presentation of its financial statements for external purposes in accordance with IFRS.

In addition, under Ternium S.A.’s articles of association, as supplemented by the audit committee’s charter, the audit committee assists the board of directors in fulfilling its oversight responsibilities relating to the effectiveness of its systems of internal control, risk management and internal audit over financial reporting. In particular, the audit committee is required to review the scope and results of the activities of Ternium S.A.’s external auditors and the internal audit function relating to its internal control over financial reporting, and obtain reports on significant findings and recommendations; and is also required to assess, at least annually at the time the annual accounts are approved, the effectiveness of Ternium S.A.’s systems of internal control and risk management over financial reporting.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements or omissions. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
135



On an yearly basis, management conducts its assessment of the effectiveness of Ternium’s internal control over financial reporting based on the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

On February 18, 2025, management reported to the audit committee that management had conducted its assessment of the effectiveness of Ternium S.A.’s internal control over financial reporting as of December 31, 2024, and that, based on management’s evaluation and considering the inherent limitations to the effectiveness of any internal control system, management concluded that the internal control over financial reporting was effective as of December 31, 2024.

The effectiveness of Ternium S.A.’s internal control over financial reporting as of December 31, 2024, has been audited by PwC Luxembourg, as stated in their report included herein. See “Attestation Report of Registered Public Accounting Firm.”
 

Attestation Report of Registered Public Accounting Firm
 
See page F-1 of the audited consolidated financial statements included in this annual report.

Change in Internal Control over Financial Reporting
 
On July 3, 2023, the company completed the acquisition of an additional participation in Usiminas and began to fully consolidate Usiminas’s balance sheet and results of operations in Ternium’s consolidated financial statements. In addition, Usiminas has been included into Ternium S.A.’s assessment of internal controls over financials reporting as of December 31, 2024. Except as disclosed above, there was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the period covered by this Annual Report on Form 20-F that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 16A. Audit Committee Financial Expert
 
Ternium S.A.’s board of directors has determined that none of the audit committee members meets the attributes defined in Item 16A of Form 20-F for “audit committee financial experts”. However, the audit committee as a whole has sufficient relevant knowledge of the business and financial experience to properly discharge its functions. In addition, the audit committee has the authority to engage, at Ternium S.A.’s expense, independent counsel and other internal or external advisors to review, investigate or otherwise advise on, any matter, as the audit committee may determine to be necessary to carry out its purposes and responsibilities.

Item 16B. Code of Ethics
 
The company has adopted a general code of conduct incorporating guidelines and standards of integrity and transparency applicable to all directors, officers and employees. As far as the nature of each relation permits, all principles detailed in the code of conduct also apply to relations with our contractors, subcontractors, suppliers and associated persons. In addition, the company has adopted a code of ethics, which is intended to supplement the company's code of conduct, and applies specifically to the principal executive officer, the principal financial officer, the principal accounting officer or controller, as well as persons performing similar functions.

Our code of conduct and our code of ethics for senior financial officers are posted on our website at:
“https://www.ternium.com/media/hjqbvp0a/tx-code-of-conduct.pdf” and
“https://www.ternium.com/media/4a3gmogx/c-ethics_ternium.pdf”, respectively.

Item 16C. Principal Accountant Fees and Services
 
Fees Paid to the Company’s Principal Accountant
 
In 2024 and 2023, PwC Luxembourg served as the principal external auditor for the company. Fees paid to PwC Luxembourg and other PwC member firms for the years ended December 31, 2024 and December, 2023 are detailed below: 
  For the year ended December 31,
In thousands of U.S. dollars 2024 2023
Audit fees 3,954  4,783 
Audit-related fees 338  268 
All other fees 119  289 
Total 4,411  5,340 
 
Audit Fees
 
Audit fees were paid for professional services rendered by the external auditors for the audit of the consolidated financial statements and internal control over financial reporting of the company, the statutory financial statements of Ternium S.A. and its subsidiaries, and any other audit services required in connection with the filings with the SEC or other regulatory filings.
 

Audit-Related Fees
 
Audit-related fees are typically referred to services that are reasonably related to the performance of the audit or review of the consolidated financial statements of the company, or the statutory financial statements of the company and its subsidiaries, and are not reported under the audit fee item above. This item includes fees for attestation services on financial information of the company and its subsidiaries included in annual reports filed with the applicable regulators.
 
Audit Committee’s Pre-approval Policies and Procedures
 
Ternium S.A.’s audit committee is responsible for, among other things, the oversight of external auditors. The audit committee has adopted in its charter a policy of pre-approval of audit and permissible non-audit services provided by its external auditors.

Under the policy, the audit committee makes its recommendations to the shareholders’ meeting concerning the continuing appointment or termination of the company’s external auditors. On a yearly basis, the audit committee reviews together with management and the external auditor, the audit plan, audit related services and other non-audit services and approves, ad-referendum of the general shareholders’ meeting, the related fees. Any changes to the approved fees must be reviewed and approved by the audit committee. The general shareholders’ meeting normally approves such audit fees and authorizes the audit committee to approve any increase or reallocation of such audit fees as may be necessary, appropriate or desirable under the circumstances. No services outside the scope of the audit committee’s approval can be undertaken by the external auditor.
 
During 2024, the audit committee did not approve any fees pursuant to the de minimis exception to the pre-approval requirement provided by paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

Item 16D. Exemptions from the Listing Standards for Audit Committees
 
Not applicable. 

Item 16E. Purchases of Equity Securities by the Issuer and Affiliated Purchasers
 
137


There were no purchases of any class of registered equity securities of Ternium S.A. by Ternium S.A. or, to our knowledge, by any other affiliated purchaser, during 2024.

The annual general meeting of shareholders held on May 3, 2021, authorized Ternium S.A. and its subsidiaries, for a period of five years, to purchase, acquire or receive, from time to time, Ternium S.A.'s shares, including shares represented by ADSs (collectively, “Securities”), on the terms and conditions set forth below.

•Purchases, acquisitions or receipts of Securities may be made in one or more transactions as Ternium S.A.'s board of directors or the board of directors or other governing body of the relevant entity, as applicable, considers advisable.

•The maximum number of Securities acquired pursuant to this authorization may not exceed 10% of Ternium S.A.’s issued and outstanding shares or, in the case of acquisitions made through a stock exchange in which the Securities are traded, such lower amount as may not be exceeded pursuant to any applicable laws or regulations of such market. The number of Securities acquired as a block may amount to the maximum permitted amount of purchases.

•The purchase price per share to be paid in cash may not exceed 125% (excluding transaction costs and expenses), nor may it be lower than 75% (excluding transaction costs and expenses), in each case of the average of the closing prices of the Securities in the stock exchange through which the Securities are acquired, during the five trading days in which transactions in the Securities were recorded in such stock exchange preceding (but excluding) the day on which the Securities are acquired. For over-the-counter or off-market transactions, the purchase price per ADS to be paid in cash may not exceed 125% (excluding transactions costs and expenses) nor may it be lower than 75% (excluding transaction costs and expenses), in each case of the average of the closing prices of the ADSs in the New York Stock Exchange during the five trading days in which transactions in ADSs were recorded in the New York Stock Exchange preceding (but excluding) the day on which the ADSs are acquired, and, in the case of acquisition of Securities, other than in the form of ADSs, such maximum and minimum per Security purchase prices shall be equal to the prices that would have applied in case of an ADS purchase pursuant to the formula above divided by the number of underlying shares represented by an ADS at the time of the relevant purchase. Compliance with maximum and minimum purchase price requirements in any and all acquisitions made pursuant to this authorization (including, without limitation, acquisitions carried out through the use of derivative financial instruments or option strategies) shall be determined on and as of the date on which the relevant transaction is entered into, irrespective of the date on which the transaction is to be settled.

•The above maximum and minimum purchase prices shall, in the event of a change in the par value of the shares, a capital increase by means of a capitalization of reserves, a distribution of shares under compensation or similar programs, a stock split or reverse stock split, a distribution of reserves or any other assets, the redemption of capital, or any other transaction impacting on equity, be adapted automatically, so that the impact of any such transaction on the value of the shares shall be reflected.

•The acquisitions of Securities may not have the effect of reducing Ternium S.A.'s net assets below the sum of capital stock plus its undistributable reserves.

•Only fully paid-up Securities may be acquired pursuant to this authorization.

•The acquisitions of Securities may be carried out for any purpose, as may be permitted under applicable laws and regulations, including, without limitation, to reduce Ternium S.A.'s share capital, to offer such Securities to third parties in the context of corporate mergers or acquisitions of other entities or participating interests therein, for distribution to Ternium S.A.'s or its subsidiaries’ directors, officers or employees or to meet obligations arising from convertible debt instruments.

•The acquisitions of Securities may be carried out by any and all means, as may be permitted under applicable laws and regulations, including through any stock exchange in which the Securities are traded, through public offers to Ternium S.A.'s shareholders to buy Securities, through the use of derivative financial instruments or option strategies, or in over-the-counter or off-market transactions or in any other manner.

•The acquisitions of Securities may be carried out at any time and from time to time during the duration of the authorization, including during a tender offer period, as may be permitted under applicable laws and regulations.

138


•The authorization granted to acquire Securities shall be valid for such maximum period as may be provided for under applicable Luxembourg law as in effect from time to time (such maximum period being, as of to date, five years).

•The acquisitions of Securities shall be made at such times and on such other terms and conditions as may be determined by Ternium S.A.'s board of directors or the board of directors or other governing body of the relevant entity, provided that any such purchase shall comply with Article 430-15 et seq. of the Luxembourg Company Law and, in the case of acquisitions of Securities made through a stock exchange in which such Securities are traded, with any applicable laws and regulations of such market.

In the future, we may, on the terms and subject to the conditions above referenced, initiate a share capital repurchase or similar program or engage in other transactions pursuant to which we would repurchase, directly or indirectly, Securities. In addition, we or our subsidiaries may enter into transactions involving sales or purchases of derivatives or other instruments (either settled in cash or through physical delivery of Securities) with returns linked to the Securities. The timing and amount of repurchase transactions under any such program, or sales or purchases of derivatives or other instruments, would depend on market conditions as well as other corporate and regulatory considerations. 

Item 16F. Change in Registrant’s Certifying Accountant
 
Not applicable. 

Item 16G. Corporate Governance

Ternium S.A.'s corporate governance practices are governed by the Luxembourg Company Law, as amended, its articles of association and applicable securities laws and regulations. As a Luxembourg company listed on NYSE, Ternium S.A. is required to comply with some, but not all, of the corporate governance standards of NYSE. We, however, believe that Ternium S.A.'s corporate governance practices meet, in all material respects, the corporate governance standards that are generally required for controlled companies by NYSE.

The following is a summary of the significant ways that Ternium S.A.'s corporate governance practices differ from the corporate governance standards required for foreign controlled companies by NYSE. Ternium S.A.’s corporate governance practices may differ in non-material ways from certain other standards required by NYSE that are not detailed here:

Non-management directors’ meetings

Under NYSE standards, non-management directors must meet at regularly scheduled executive sessions without management present and, if such group includes directors who are not independent, a meeting should be scheduled once per year including only independent directors. Neither Luxembourg law nor Ternium S.A.’s articles of association require the holding of such meetings and Ternium S.A. does not have a set policy for these meetings. For additional information on board meetings, please see Item 6. “A. Directors, Senior Management and Employees—Board of Directors”.

In addition, NYSE-listed companies are required to provide a method for interested parties to communicate directly with non-management directors as a group. While Ternium S.A. does not have such a method, it has set up a compliance line for investors and other interested parties to communicate their concerns directly to the members of our audit committee, all of whom are non-management independent directors.
 
Audit committee composition
 
Under NYSE standards, listed U.S. companies are required to have an audit committee composed of independent directors that satisfy the requirements of Rule 10A-3 promulgated under the Exchange Act. Pursuant to Ternium S.A.,’s articles of association, as supplemented by the audit committee’s charter, for as long as Ternium S.A.'s shares are listed on at least one regulated market, the Ternium S.A. must have an audit committee composed of at least three members, the majority of whom must qualify as independent directors (as defined in the articles of association), provided, however, that the composition and membership of the audit committee shall satisfy such requirements as are applicable to, and mandatory for, audit committees of issuers such as Ternium S.A. under any applicable law, rule or regulation (including, without limitation, the applicable laws, rules and regulations of such regulated market or markets).
139


The audit committee, which currently consists of three members, complies with such requirements. In accordance with NYSE standards, Ternium S.A. has an audit committee entirely composed of independent directors for purposes of the Exchange Act Rule 10A-3(b)(1). For more information on the audit committee see Item 6. “Directors, Senior Management and Employees—C. Board Practices-Audit Committee”.
 
Under NYSE standards, all audit committee members of listed U.S. companies are required to be financially literate or must acquire such financial knowledge within a reasonable period and at least one of its members shall have experience in accounting or financial administration. In addition, if a member of the audit committee is simultaneously a member of the audit committee of more than three public companies, and the listed company does not limit the number of audit committees on which its members may serve, then in each case the board must determine whether the simultaneous service would prevent such member from effectively serving on the listed company’s audit committee and shall publicly disclose its decision. No comparable provisions on audit committee membership exist under applicable Luxembourg law or Ternium S.A.'s articles of association.

Standards for evaluating director independence
 
Under NYSE standards, the board is required, on a case-by-case basis, to express an opinion with regard to the independence or lack of independence of each individual director. Neither Luxembourg law nor our articles of association requires that the board of directors express such an opinion. In addition, the definition of “independent” under NYSE rules differs in some non-material respects from the definition contained in articles of association. For more information on Ternium S.A.'s independent directors and the definition of “independent” under the articles of association, see Item 6. “Directors, Senior Management and Employees—C. Board Practices-Audit Committee”. 

Audit committee responsibilities
 
Pursuant to the articles of association, the audit committee shall assist the board of directors in fulfilling its oversight responsibilities relating to the integrity of its consolidated financial statements, the effectiveness of its systems of internal control, risk management and internal audit over financial reporting and the independence and performance of the external auditors. The audit committee is required to review and, where applicable, approve material transactions between Ternium S.A. or its subsidiaries and related parties and also perform the other duties entrusted to it by the board. NYSE requires certain matters to be set forth in the audit committee charter of U.S. listed companies.

The audit committee's charter provides for many of the responsibilities that are expected from such bodies under the NYSE standard; however, due to Ternium S.A.’s equity structure and holding company nature, the charter does not contain all such responsibilities, including provisions related to procedures for the receipt and treatment of complaints other than complaints regarding accounting, internal accounting controls and audit matters (although the company has established such procedures), funding for payment of administrative expenses and compensation to advisors (although the audit committee has the authority to engage outside advisors), setting hiring policies for employees or former employees of external auditors and an annual performance evaluation of the audit committee. For more information on Ternium S.A.’s audit committee see Item 6. “Directors, Senior Management and Employees—C. Board Practices-Audit Committee”.
 
Standards for approval of related-party transactions

Ternium S.A. is subject to Luxembourg laws governing approval of material related party transactions; and the articles of association and the audit committee's charter require the audit committee to review material transactions with related parties to determine whether their terms are consistent with the interests of Ternium S.A. and its shareholders and with market conditions or are otherwise fair to Ternium S.A. and its subsidiaries. In addition, NYSE standard on related-party transactions requires all NYSE-listed companies’ audit committees (or another independent body of the board of directors) to conduct a reasonable prior review and oversight of all related party transactions for potential conflicts of interest and to prohibit such a transaction if it determines it to be inconsistent with the interests of Ternium S.A. and its shareholders. The rule defines the term “related party transaction” by reference to the disclosure requirements for annual reports under the Exchange Act. The materiality threshold applicable to foreign private issuers differs to the one applicable to U.S companies. For further details on the approval process for related party transactions, see Item 6.C. “Directors, Senior Management and Employees – Board Practices – Audit Committee”.

Shareholder voting on equity compensation plans
 
140


Under NYSE standards, shareholders must be given the opportunity to vote on equity-compensation plans and material revisions thereto, except for employment inducement awards, certain grants, plans and amendments in the context of mergers and acquisitions, and certain specific types of plans. Ternium does not currently offer equity-based compensation to its directors, officers or employees, and therefore does not have a policy on this matter. For further information on directors' compensation, see Item 6. “Directors, Senior Management and Employees—B. Compensation”.
 
Disclosure of corporate governance guidelines
 
NYSE-listed companies must adopt and disclose corporate governance guidelines. Neither Luxembourg law nor the articles of association require the adoption or disclosure of corporate governance guidelines. The board of directors follows corporate governance guidelines consistent with its equity structure and holding company nature, but Ternium S.A. has not codified them and therefore does not disclose them on its website.
 
Code of business conduct and ethics

In addition, it has adopted a supplementary code of ethics for senior financial officers which is also posted on our website. For further information, see Item 16B. “Code of Ethics”.

Item 16K. Cybersecurity

Under Ternium S.A.’s articles of association, as supplemented by the audit committee’s charter, the audit committee assists the board of directors in fulfilling its oversight responsibilities relating to the effectiveness of its systems of internal control, risk management and internal audit over financial reporting. In addition, Ternium S.A. has established a management-level Critical Risk Committee (“CRC”) in connection with the monitoring, assessment and review of risks to which Ternium is exposed and in the oversight of the risk management framework and processes, with a focus on critical risks (including among them, cybersecurity risks), the development of mitigating actions, and the monitoring of action plans. The CRC is composed of certain senior managers, including the Chief Information Officer, the Global Cybersecurity Director, the Chief Financial Officer and the Chief Executive Officer. The Chief Financial Officer oversees the risk management strategy. In particular with respect to cybersecurity risks, Ternium S.A. has appointed an Information Security Officer who is responsible for assessing cybersecurity risks and managing cybersecurity incidents, and reports to the Chief Information Officer, who, in turn, reports to the Chief Financial Officer. Ternium S.A.’s board of directors receives quarterly reports from the Chief Executive Officer and the Chief Financial Officer on risk management, including cybersecurity risk management and relevant cybersecurity incidents. In addition, at least once a year, the Chief Information Officer reports to the board of directors on Ternium S.A.’s cybersecurity management

Identified risks, including cybersecurity risks, are categorized as critical, very significant, significant or less significant, based on their potential impact, likelihood of occurrence and severity. Currently cybersecurity risks are categorized as critical, very significant, significant and less significant. Critical, very significant and significant risks and are assessed or reassessed at least three times per year.

In today's digital age, where cybersecurity is a critical priority for organizations, collaboration with third-party service providers has become increasingly common and necessary. Third-party service providers play a critical role in strengthening information security processes, providing specialized expertise and additional resources to address the complexities of the ever-evolving cyber threat landscape.

Our Global Cybersecurity Director leads our cybersecurity team, acting as the internal focal point for risk management and implementation of security controls. However, we recognize that cybersecurity encompasses a wide range of expertise, and it is in these cases that we turn to specialized consultants. Specialized cybersecurity consultants are engaged when specific expertise is required to address particular challenges or to conduct comprehensive risk assessments. These professionals bring a valuable external perspective, offering expertise and skills that complement our team's internal capabilities. Tasks and responsibilities outsourced to third-party service providers may include:

1.    Risk and Vulnerability Assessment: Consultants can conduct comprehensive risk assessments and vulnerability scans to identify potential gaps in our security infrastructure.

2.    Security audits: They perform independent audits to ensure compliance with information security standards and regulations, or industry-specific regulations.

3.    Penetration Testing: Consultants perform ethical penetration tests to identify weaknesses in our network and systems, simulating real attacks to evaluate the resistance of our defenses.

4.    Development of security policies and controls: They collaborate in the creation and review of information security policies, as well as in the design and implementation of appropriate controls to mitigate risks.

5.    Training and awareness: They provide cybersecurity training and awareness programs for our staff, helping to promote a culture of security throughout the organization.

6.    Security Operation Centers ("SOC"): The SOC plays a critical role in detecting, analyzing and responding to security incidents in real time.

Tasks are distributed between external vendors and the Global Cybersecurity Director based on the nature and scope of each project. The Global Cybersecurity Director and his team closely monitor all cybersecurity-related activities, ensuring that they align with the organization's security objectives and standards. In addition, he or she coordinates communication and collaboration between third-party vendors and other relevant internal teams, ensuring effective integration of cybersecurity efforts across the enterprise. Third-party vendors are carefully selected based on their experience, credentials and demonstrated capabilities in the cybersecurity field. We look for partners who hold recognized certifications, and who have a proven track record of success in similar projects.
142


Transparency and trust are core values in our relationship with third-party vendors, and we work closely with them to ensure comprehensive protection of our information assets.

Our Global Cybersecurity Director has been working on Ternium’s cybersecurity area since 2006. He holds a degree in Information Systems Engineering and a CISM-Certified Information Security Manager certification from ISACA.

As Ternium relies heavily on information systems to conduct its operations, it has adopted information security policies and controls aligned with the industry’s best practices and standards, in compliance with international frameworks including the U.S. National Institute of Standards and Technology, or NIST, the Open Worldwide Application Security Project, or OWASP, and ISO, among others.

Our information security teams regularly evaluate the effectiveness of our policies and controls, learning from past incidents and implementing continuous improvements. We closely evaluate and supervise the information security practices of our suppliers and third parties with access to our assets and critical data.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated statements of financial position of Ternium S.A. and its subsidiaries (the “Company”) as of 31 December 2024 and 2023, and the related consolidated income statements, consolidated statements of comprehensive income, consolidated statements of changes in equity and consolidated statements of cash flows for each of the three years in the period ended 31 December 2024, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of 31 December 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of 31 December 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended 31 December 2024 in conformity with IFRS Accounting Standards as issued by the International Accounting Standards Board and IFRS Accounting Standards as adopted by the European Union. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of 31 December 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.
____________________________________________________________________________________
Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control over Financial Reporting appearing under Item 15. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits.

We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
____________________________________________________________________________________
Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

____________________________________________________________________________________
Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Litigation - Acquisition of a participation in Usiminas
.
As described in Notes 4(p) and 25(i)(a) to the consolidated financial statements, the Company has a provision for the litigation related to acquisition of a participation in Usiminas for 410.2 million USD at 31 December 2024. Provisions are recognised when the Company has a present legal or constructive obligation as a result of past events, it is probable that an outflow of resources will be required to settle the obligation and the amount can be reliably estimated. The Company also discloses the contingency in circumstances where management concludes no loss is probable or reasonably estimable but it is reasonably possible that a loss may be incurred.

The principal considerations for our determination that performing procedures relating to the litigation related to the acquisition of a participation in Usiminas is a critical audit matter are (i) the significant judgment by management when assessing whether a loss is probable and when determining whether the amount of the loss or range of loss can be reasonably estimated, and (ii) a high degree of auditor judgment and effort in performing procedures and evaluating audit evidence related to management’s assessment of the legal contingency.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s assessment of the litigation related to the acquisition of a participation in Usiminas, including controls over determining whether a loss is probable and when determining whether the amount of loss or range of loss can be reasonably estimated, as well as financial statement disclosures. These procedures also included, among others, (i) confirming with internal and external legal counsel the possibility or probability of an unfavorable outcome and the extent to which the loss or range of loss is reasonably estimable; (ii) evaluating the reasonableness of management’s assessment regarding whether an unfavorable outcome is reasonably possible or probable and reasonably estimable; and (iii) evaluating the sufficiency of the Company’s litigation disclosures in the consolidated financial statements.

Notes to the Consolidated Financial Statements
1.    GENERAL INFORMATION
Ternium S.A. (the “Company” or “Ternium”), was incorporated on December 22, 2003 to hold investments in flat and long steel manufacturing and distributing companies. The Company has an authorized share capital of a single class of 3.5 billion shares having a nominal value of $1.00 per share. As of December 31, 2024, there were 2,004,743,442 shares issued. All issued shares are fully paid.

Ternium’s American Depositary Shares (“ADSs”) trade on the New York Stock Exchange under the symbol “TX”.

The Company was initially established as a public limited liability company (société anonyme) under Luxembourg’s 1929 holding company regime. Until termination of such regime on December 31, 2010, holding companies incorporated under the 1929 regime (including the Company) were exempt from Luxembourg corporate and withholding tax over dividends distributed to shareholders.

On January 1, 2011, the Company became an ordinary public limited liability company (société anonyme) and, effective as from that date, the Company is subject to all applicable Luxembourg taxes (including, among others, corporate income tax on its worldwide income) and its dividend distributions will generally be subject to Luxembourg withholding tax. However, dividends received by the Company from subsidiaries in high income tax jurisdictions, as defined under Luxembourg law, will continue to be exempt from corporate income tax in Luxembourg under Luxembourg’s participation exemption.

As part of the Company’s corporate reorganization in connection with the termination of Luxembourg’s 1929 holding company regime, on December 6, 2010, the Company contributed its equity holdings in all its subsidiaries and all its financial assets to its Luxembourg wholly-owned subsidiary Ternium Investments S.à r.l., or Ternium Investments, in exchange for newly issued corporate units of Ternium Investments. As the assets contributed were recorded at their historical carrying amount in accordance with Luxembourg GAAP, the Company’s December 2010 contribution of such assets to Ternium Investments resulted in a non-taxable revaluation of the accounting value of the Company’s assets under Luxembourg GAAP. The amount of the December 2010 revaluation was equal to the difference between the historical carrying amounts of the assets contributed and the value at which such assets were contributed and amounted to $4.0 billion. However, for the purpose of these consolidated financial statements, the assets contributed by Ternium to its wholly-owned subsidiary Ternium Investments were recorded based on their historical carrying amounts in accordance with IFRS, with no impact on the financial statements.

Following the completion of the corporate reorganization, and upon its conversion into an ordinary Luxembourg holding company, the Company voluntarily recorded a special reserve exclusively for tax-basis purposes. As of December 31, 2024 and 2023, this special tax reserve amounted to $4.1 billion and $4.7 billion, respectively. The Company expects that, as a result of its corporate reorganization, its current overall tax burden will not increase, as all or substantially all of its dividend income will come from high income tax jurisdictions.

3.    ACQUISITION OF BUSINESS – INCREASE OF THE PARTICIPATION IN USIMINAS CONTROL GROUP AND NEW GOVERNANCE STRUCTURE OF USIMINAS

     (a) The participation in Usiminas as of June 30, 2023

On January 16, 2012, the Company’s subsidiaries, Ternium Investments and Ternium Argentina (together with its wholly-owned subsidiary Prosid Investments S.A., or "Prosid", and the Company’s affiliate, Confab Industrial S.A., a subsidiary of Tenaris, or TenarisConfab), joined the existing control group of Usiminas, a leading steel company in the Brazilian flat steel market, through the acquisition of 84.7, 30.0, and 25.0 million ordinary shares, respectively, and formed the so-called Ternium/Tenaris (T/T) Group.

On October 30, 2014, Ternium Investments acquired 51.4 million additional ordinary shares of Usiminas. On April 20, 2016, Ternium Investments subscribed to 7.0 million preferred shares of Usiminas and Ternium Argentina, together with Prosid, subscribed to an aggregate 1.5 million preferred shares of Usiminas. On July 19, 2016, Usiminas’ extraordinary general shareholders’ meeting homologated a capital increase, and Ternium Investments acquired 62.6 million additional ordinary shares, and Ternium Argentina and Prosid acquired an aggregate 13.8 million additional ordinary shares. As a result of these transactions, Ternium, through its subsidiaries Ternium Investments, Ternium Argentina and Prosid, owned as of June 30, 2023, 242.6 million ordinary shares of Usiminas (representing 34.4% of Usiminas’ ordinary shares) and 8.5 million of Usiminas’ preferred shares (representing 1.6% of Usiminas’ preferred shares), representing, in the aggregate, 20.4% of Usiminas’ share capital.

As of June 30, 2023, the Usiminas control group held, in the aggregate, 483.6 million ordinary shares bound to the Usiminas shareholders’ agreement, representing approximately 68.6% of Usiminas’ voting capital. The Usiminas control group, which was bound by a long-term shareholders’ agreement that governs the rights and obligations of Usiminas’ control group members, was composed as of such date of three sub-groups: the T/T Group; the NSC Group, comprising Nippon Steel Corporation (“NSC”), Metal One Corporation and Mitsubishi Corporation; and Usiminas’ pension fund Previdência Usiminas. The T/T Group held approximately 47.1% of the total shares held by the control group (39.5% corresponding to the Ternium entities and the other 7.6% corresponding to TenarisConfab); the NSC Group held approximately 45.9% of the total shares held by the control group; and Previdência Usiminas held the remaining 7%. The corporate governance rules reflected in the Usiminas shareholders agreement provided, among other things, that Usiminas’ executive board was composed of six members, including the chief executive officer and five vice-presidents, with Ternium and NSC nominating three members each. The right to nominate Usiminas’ chief executive officer alternated between Ternium and NSC at every 4-year interval, with the party that did not nominate the chief executive officer having the right to nominate the chairman of Usiminas’ board of directors for the same 4-year period. The Usiminas shareholders agreement also provided for an exit mechanism consisting of a buy-and-sell procedure—exercisable at any time after November 16, 2022, and applicable with respect to shares held by NSC and the T/T Group—, which would allow either Ternium or NSC to purchase all or a majority of the Usiminas shares held by the other shareholder.

(b) The acquisition of the additional participation

On March 30, 2023, Ternium S.A. announced that its subsidiaries Ternium Investments and Ternium Argentina, together with Confab, a subsidiary of its affiliate Tenaris S.A., all of which compose the T/T group within Usiminas control group, entered into a share purchase agreement to acquire from Nippon Steel Corporation, Mitsubishi and MetalOne (the “NSC group”), pro rata to their current participations in the T/T group, 68.7 million ordinary shares of Usinas Siderúrgicas de Minas Gerais S.A. - USIMINAS ("Usiminas") at a price of BRL10 per ordinary share.

3.    ACQUISITION OF BUSINESS – INCREASE OF THE PARTICIPATION IN USIMINAS CONTROL GROUP AND NEW GOVERNANCE STRUCTURE OF USIMINAS (continued)

On July 3, 2023, the Company announced the completion of the acquisition of this additional participation. Pursuant to the transaction, Ternium paid $118.7 million in cash for 57.7 million ordinary shares, increasing its participation in the Usiminas control group to 51.5%.

The Usiminas control group holds the majority of Usiminas’ voting rights. Following the completion of the transaction, the T/T group holds an aggregate participation of 61.3% in the control group, with the NSC group and Previdência Usiminas (Usiminas employees’ pension fund) holding 31.7% and 7.1%, respectively. The Usiminas control group members also agreed a new governance structure, as a result of which the T/T group nominated a majority of the Usiminas board of directors, the CEO and four other members of Usiminas board of officers, and ordinary decisions are approved with a 55% majority of the control group shares.

Pursuant to the Usiminas shareholders agreement, as supplemented by the T/T Group shareholders’ agreement, Ternium started fully consolidating Usiminas balance sheet and results of operations in its consolidated financial statements beginning in July 2023.

(c) Remeasurement of the previously held interest

As of July 3, 2023, Ternium remeasured its former participation (20.4%) at its fair value as of such date.

Consequently, Ternium valued its previously held interest by means of the market quotation of Usiminas share in the Brazilian stock market. Such value as of July 3, 2023, was of 7.36 BRL per share, amounting to a total of $385.9 million. This valuation results in the recognition of a loss of $441.4 million, which is included along with the gain related to the bargain purchase amounting to $270.4 million (see note 3 (d)) in the “Effect related to the increase of the participation in Usiminas” in the income statement for a total of $171.0 million.

In addition, IFRS 3, paragraph 42, establishes that the previous interest must be remeasured, and necessary adjustments made as if it were a disposal of the investment. In this case, items previously recognized in other comprehensive income, mainly the CTA (currency translation adjustment) should be recycled to results of the period. The accumulated loss in “Other comprehensive income” as of the acquisition date was $934.9 million.

(d) Fair value of net assets acquired

The fair values determined for the assets acquired and liabilities assumed arising from the acquisition are as follows:

Fair value of acquired assets and assumed liabilities: in $ thousands
Property, plant and equipment (note 12) 904,780 
Investments in non-consolidated companies 400,037 
Inventories 1,707,311 
Cash and cash equivalents 781,072 
Other investments 247,005 
Trade receivables 764,257

Other receivables 854,917 
Deferred tax assets 1,327,232 
Borrowings (1,224,399)
Provisions (856,153)
Trade payables (758,687)
Other assets and liabilities, net (509,486)
Net assets acquired 3,593,260 
Non-controlling interest (2,818,358)
Remeasurement of previously held interest in Usiminas (385,851)
Total Purchase consideration (118,686)
Bargain purchase gain 270,365 
Loss on the remeasurement of previously held interest in Usiminas (441,410)
Net loss effect related to the increase of the participation in Usiminas (171,045)


The purchase price allocation disclosed above was prepared with the assistance of a third-party expert. Management applied significant judgment in estimating the fair value of assets acquired and liabilities assumed, which involved the use of significant estimates and assumptions in particular with respect to the estimation of the loss probability for the contingencies, including revenue forecasts, EBITDA margins, capital expenditures and discount rate for the cash flow projections. According to the purchase price allocation, the transaction led to the recognition of a bargain purchase of $270.4 million.

(e) Put and call option

In addition to the share purchase and the new governance structure, a “put” and “call” mechanism was established according to the following scheme:

–NSC group will have the right, at any time after the closing of the transaction, to withdraw its remaining shares from the control group and sell them in the open market after giving the T/T group the opportunity to buy them at the equivalent in U.S. dollars of the 40-trading day average price per share immediately prior to the NSC group’s notice of withdrawal, as well as the right, at any time after the second anniversary of the closing, to sell such shares to the T/T group at $2.0584 per share.

3.    ACQUISITION OF BUSINESS – INCREASE OF THE PARTICIPATION IN USIMINAS CONTROL GROUP AND NEW GOVERNANCE STRUCTURE OF USIMINAS (continued)

–At any time after the second anniversary of the closing of the transaction, the T/T group will have the right to buy the NSC group’s remaining interest in the Usiminas control group (153.1 million ordinary shares) at the higher of $2.0584 per share and the equivalent in U.S. dollars of the 40-trading day average price per share immediately prior to the date of exercising the option.
–In the case of the T/T Group, Ternium will decide at its own discretion the execution of the call option, having Confab and Ternium Argentina the option to acquire the shares owned by NSC pro rata to their participation.

IAS 32 requires a liability to be recognized for written puts over non-controlling interests. The liability reflects the entity’s obligation to deliver cash or a financial asset. The financial liability is recognized at present value of the redemption amount and accreted through finance charges in the income statement over the contract period up to the final redemption amount. Ternium has recognized a liability associated with the put option of $242.5 million ($263.2 million as of December 31, 2024), accounted for in the statement of financial position under Other liabilities, with the corresponding debit in the statement of changes in equity under Non-controlling interest.

(f) Recognition of non-controlling interest

Ternium recognizes non-controlling interests in an acquired entity either at fair value or at the non-controlling interest’s proportionate share of the acquired entity’s net identifiable assets. This decision is made on an acquisition-by-acquisition basis. For the non-controlling interests in Usiminas, the Company elected to recognize the non-controlling interests at its proportionate share of the acquired net identifiable assets, which led to a non-controlling interest of $2,575.9 million, as of the acquisition date.

(g) Main contingencies associated with the acquired business

Contrary to the recognition principles in IAS 37 Provisions, Contingent Liabilities and Contingent Assets, IFRS 3 Business Combinations requires an acquirer of a business to recognize contingent liabilities assumed in a business acquisition at the acquisition date even if it is not probable that an outflow of resources will be required to settle the obligation.

Labour related contingencies (49,655)
Total Provision for contingencies (856,153)

Contingencies estimated by Management were related to possible losses arising from administrative proceedings and litigation related to tax, civil and labor matters and based on the advice and assessment of internal and external legal advisors.

4.    ACCOUNTING POLICIES

The following is a summary of the principal accounting policies followed in the preparation of these Consolidated Financial Statements:

(a)Group accounting
(1)    Subsidiary companies and transactions with non-controlling interests
Subsidiaries are all entities over which the Company has control. The Company controls an entity when the Company is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Company. They are deconsolidated from the date that control ceases.

The Company uses the acquisition method of accounting to account for business combinations. The consideration transferred for the acquisition of a subsidiary is the fair values of the assets transferred, the liabilities incurred and the equity interests issued by the Company. The consideration transferred includes the fair value of any asset or liability resulting from a contingent consideration arrangement. Acquisition-related costs are expensed as incurred. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at the fair values at the acquisition date. Indemnification assets are recognized at the same time that the Company recognizes the indemnified item and measures them on the same basis as the indemnified item, subject to the need for a valuation allowance for uncollectible amounts. The Company measures the value of a reacquired right recognized as an intangible asset on the basis of the remaining contractual term of the related contract regardless of whether market participants would consider potential contractual renewals in determining its fair value.

The Company recognizes any non-controlling interest in the acquiree at the non-controlling interest's proportionate share of the acquiree's net identifiable assets. The recognition of business combinations requires the acquirer to measure at the acquisition date components of non‑controlling interests in the acquiree that are present ownership interests and entitle their holders to a proportionate share of the entity’s net assets in the event of liquidation at either (a) fair value; or (b) the present ownership instruments’ proportionate share in the recognized amounts of the acquiree’s identifiable net assets. The Company opted for the proportional share in the recognized amounts of the identifiable net assets for the recognition described in note 3 related to Usiminas.

The excess of the consideration transferred, the amount of any non-controlling interest in the acquiree and the acquisition-date fair value of any previous equity interest in the acquiree over the fair value of the Company's share of the identifiable net assets acquired is recorded as goodwill. If this is less than the fair value of the net assets of the subsidiary acquired in the case of a bargain purchase, the difference is recognized directly in the income statement.

The measurement period is the earlier of the date that the acquirer receives the information that it is looking for or cannot obtain the information and one year after the acquisition date. Where the accounting for a business combination is not complete by the end of the reporting period in which the business combination occurred provisional amounts are reported.

The Company treats transactions with non-controlling interests as transactions with equity owners of the Company. For purchases from non-controlling interests, the difference between any consideration paid and the relevant share acquired of the carrying value of net assets of the subsidiary is recorded in equity. Gains or losses on disposals to non-controlling interests are also recorded in equity.

TERNIUM S.A.
Consolidated Financial Statements as of December 31, 2024 and 2023
and for the years ended December 31, 2024, 2023 and 2022

4.    ACCOUNTING POLICIES (continued)
When the Company ceases to have control or significant influence, any retained interest in the entity is remeasured to its fair value, with the change in carrying amount recognized in profit or loss. The fair value is the initial carrying amount for the purposes of subsequently accounting for the retained interest as an associate, joint venture or financial asset. In addition, any amounts previously recognized in other comprehensive income in respect of that entity are accounted for as if the group had directly disposed of the related assets or liabilities. This may mean that amounts previously recognized in other comprehensive income are reclassified to profit or loss.

Inter-company transactions, balances and unrealized gains on transactions between group companies are eliminated. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the transferred asset. Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the group. However, the fact that the functional currency of some subsidiaries is their respective local currency, generates some financial gains (losses) arising from intercompany transactions, that are included in the consolidated income statement under Other financial expenses, net.    

(2) Investments in non-consolidated companies

Associated companies are those entities in which Ternium has significant influence, but which it does not control.

Joint arrangements are understood as combinations in which there are contractual agreements by virtue of which two or more companies hold an interest in companies that undertake operations or hold assets in such a way that any financial or operating decision is subject to the unanimous consent of the partners. A joint arrangement is classed as a joint operation if the parties hold rights to its assets and have obligations in respect of its liabilities or as a joint venture if the venturers hold rights only to the investee's net assets.

Investments in non-consolidated companies (associated companies and joint ventures) are accounted for using the equity method of accounting. Under this method, interests in joint ventures and associates are initially recognized in the consolidated statement of financial position at cost and adjusted thereafter to recognize the Company’s share of the post-acquisition profits or losses in the income statement, and its share of post-acquisition changes in reserves recognized in reserves and in other comprehensive income in the income statement. Unrealized gains on transactions among the Company and its non-consolidated companies are eliminated to the extent of the Company’s interest in such non-consolidated companies; unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the transferred asset. When the Company’s share of losses in a non-consolidated company equals or exceeds its interest in such non-consolidated company, the Company does not recognize further losses unless it has incurred obligations or made payments on behalf of such non-consolidated company. Accounting policies of non-consolidated companies have been changed where necessary to ensure consistency with the policies adopted by the Company.

The Company’s investment in associates and joint ventures includes notional goodwill identified on acquisition.

The Company determines at each reporting date whether there is any objective evidence that the investment is impaired. If this is the case, the group calculates the amount of impairment as the difference between the recoverable amount of the investment and its carrying value and recognizes the amount within “Equity on earnings (losses) of non-consolidated companies”.

4.    ACCOUNTING POLICIES (continued)
(b)Foreign currency translation
(1)Functional and presentation currency

Items included in the financial statements of each of the Company's subsidiaries and associated companies are measured using the currency of the primary economic environment in which the entity operates (the "functional currency"). Except for Usiminas and the non-consolidated companies whose functional currencies are their local currencies, Ternium determined that the functional currency of its subsidiaries is the U.S. dollar. Although Ternium is located in Luxembourg, it operates in several countries with different currencies. The $ is the currency that best reflects the economic substance of the underlying events and circumstances relevant to Ternium as a whole.

(2)    Subsidiary companies

The results and financial position of all the group entities (except for the ones which operated in a hyperinflationary economy, if any) that have a functional currency different from the presentation currency, are translated into the presentation currency as follows:

(i) assets and liabilities are translated at the closing rate of each statement of financial position;
(ii) income and expenses for each income statement are translated at average exchange rates (unless this average is not a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates, in which case income and expenses are translated at the rate on the dates of the transactions); and
(iii) all resulting translation differences are recognized within other comprehensive income.

In the case of a sale or other disposition of any such subsidiary, any accumulated translation differences would be recognized in the income statement as part of the gain or loss on sale.

(3)    Transactions in currencies other than the functional currency

Transactions in currencies other than the functional currency are translated into the functional currency using the exchange rates prevailing at the date of the transactions or valuation where items are re-measured.

At the end of each reporting period: (i) monetary items denominated in currencies other than the functional currency are translated using the closing rates, (ii) non-monetary items that are measured in terms of historical cost in a currency other than the functional currency are translated using the exchange rates prevailing at the date of the transactions; and (iii) non-monetary items that are measured at fair value in a currency other than the functional currency are translated using the exchange rates prevailing at the date when the fair value was determined.

Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in currencies other than the functional currency are recorded as gains and losses from foreign exchange and included in "Other financial income (expenses), net" in the consolidated income statement, except when deferred in equity as qualifying cash flow hedges and qualifying net investment hedges. Translation differences on non-monetary financial assets and liabilities such as equities held at fair value through profit or loss are recognized in profit or loss as part of the "fair value gain or loss," while translation differences on non-monetary financial assets such as equities classified as fair value through other comprehensive income are included in other gains/(losses).

(c)Financial instruments
Non derivative financial instruments
Non derivative financial instruments comprise investments in equity and debt securities, trade and other receivables, cash and cash equivalents, loans and borrowings, and trade and other payables.
The Company classifies its financial instruments in the following measurement categories:
–Amortized cost: instruments that are held for collection or repayment of contractual cash flows where those cash flows represent solely payments of principal and interest are measured at amortized cost. Interest income and expenses from these financial instruments are included in finance income or expense using the effective interest rate method. Any gain or loss arising on derecognition is recognized directly in profit or loss and presented in finance income or expense, together with foreign exchange gains and losses. Impairment losses are presented as separate line items in the statement of profit or loss.
–Fair value through other comprehensive income (“FVOCI”): financial instruments that are held for collection of contractual cash flows and for selling the financial instruments, where the instruments’ cash flows represent solely payments of principal and interest, are measured at FVOCI. Movements in the carrying amount are taken through OCI, except for the recognition of impairment gains or losses, interest revenue or expense and foreign exchange gains and losses which are recognized in profit or loss. When the financial instrument is derecognized, the cumulative gain or loss previously recognized in OCI is reclassified from equity to profit or loss and recognized in other gains/(losses), except for equity instruments, for which there is no reclassification from OCI to profit or loss. Interest income or expense from these financial instruments is included in finance income using the effective interest rate method. Foreign exchange gains and losses are presented in other gains/(losses) and impairment expenses are presented as separate line item in the statement of profit or loss.
–Fair value through profit or loss (“FVPL”): financial instruments that do not meet the criteria for amortized cost or FVOCI are measured at FVPL. A gain or loss on a debt investment that is subsequently measured at FVPL is recognized in profit or loss and presented net within other gains/(losses) in the period in which it arises.
The classification depends on the Company’s business model for managing the financial instruments and the contractual terms of the cash flows.
For financial instruments measured at fair value, gains and losses will either be recorded in profit or loss or OCI. For investments in equity instruments that are not held for trading, this will depend on whether the group has made an irrevocable election at the time of initial recognition to account for the equity investment at FVOCI.
At initial recognition, the Company measures a financial instrument at its fair value plus, in the case of a financial instrument not at FVPL, transaction costs that are directly attributable to the acquisition of the financial instrument. Transaction costs of financial instruments carried at FVPL are expensed in profit or loss. Subsequent measurement of debt instruments depends on the Company’s business model for managing the asset and the cash flow characteristics of the asset.

4.    ACCOUNTING POLICIES (continued)
The classification depended on the nature and purpose of the financial assets and was determined at the time of initial recognition.
Financial assets and liabilities were recognized and derecognized on the settlement date.
Financial assets were initially measured at fair value, net of transaction costs, except for those financial assets classified as financial assets at fair value through profit or loss.
Financial liabilities, including borrowings, were initially measured at fair value, net of transaction costs and subsequently measured at amortized cost using the effective interest method, with interest expense recognized on an effective yield basis.
Impairment of financial assets
The Company assesses on a forward-looking basis the expected credit losses associated with its debt instruments carried at amortized cost and FVOCI. The impairment methodology applied depends on whether there has been a significant increase in credit risk.
For trade receivables, the Company applies the simplified approach permitted by IFRS 9, which requires expected lifetime losses to be recognized from initial recognition of the receivables, see note 4 (i) for further details.
For loans and receivables category and for held-to-maturity investments, the amount of the loss was measured as the difference between the asset's carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the financial asset's original effective interest rate. The carrying amount of the asset was reduced and the amount of the loss was recognized in the consolidated income statement.
If, in a subsequent period, the amount of the impairment loss decreased and the decrease could be related objectively to an event occurring after the impairment was recognized, the reversal of the previously recognized impairment loss was recognized in the consolidated income statement.
Derivative financial instruments
Information about accounting for derivative financial instruments and hedging activities is included in Note 29 "Financial Risk management" and Note 4 (y).
Put option valuation method
IFRS presents the following options to recognize the value of a put option:

- Under IFRS 10, the terms of the forward and option contracts should be analyzed to assess whether they provide the parent or the non-controlling interest with access to the risks and rewards associated with the actual ownership of the shares. The non-controlling interest should be recognized if risks and rewards associated with ownership have been retained by the non-controlling interest. A financial liability (recognized at the present value of the redemption amount) is recorded to reflect the forward or put option.

4.    ACCOUNTING POLICIES (continued)

- Under IAS 32, a liability is recognized for written puts over non-controlling interests. The liability reflects the entity’s obligation to deliver cash or a financial asset. The financial liability is recognized at present value of the redemption amount and accreted through finance charges in the income statement over the contract period up to the final redemption amount.

(d)Property, plant and equipment
(1) Property, plant and equipment
Land and buildings comprise mainly factories and offices. All property, plant and equipment are recognized at historical acquisition or construction cost less accumulated depreciation and accumulated impairment (if applicable), except for land, which is carried at acquisition cost less accumulated impairment (if applicable). There are no material residual values for property, plant and equipment items.
Major overhaul and rebuilding expenditures are recognized as a separate asset when future economic benefits are expected from the item, and the cost can be measured reliably.
Ordinary maintenance expenses on manufacturing properties are recorded as cost of products sold in the period in which they are incurred.
Where a tangible fixed asset comprises major components having different useful lives, these components are accounted for as separate items. Spare parts are included in property, plant and equipment.
Depreciation method is reviewed at each year end. Depreciation is calculated using the straight-line method to amortize the cost of each asset to its residual value over its estimated useful life as follows:
Land No depreciation
Buildings and improvements
10-50 years
Production equipment
5-40 years
Vehicles, furniture and fixtures and other equipment
3-20 years
Property, plant and equipment used in mining activities are depreciated over its useful life or over the remaining life of the mine if shorter and there is no alternative use possible.
The assets' useful lives are reviewed, and adjusted if appropriate, at each year end. The re-estimation of assets useful lives by the Company did not materially affect depreciation charges in 2024, 2023 and 2022.
Gains and losses on disposals are determined by comparing the proceeds with the corresponding carrying amounts and are included in the income statement.
If the carrying amount of an asset were greater than its estimated recoverable amount, it would be written down to its recoverable amount (see Note 4 (f) "Impairment").
Amortization charges are included in cost of sales, selling, general and administrative expenses.

(2) Right-of-use assets
The Company is a party to lease contracts for:
–Land
–Plants and equipment for the production of industrial gases and other production materials.
–Transportation and maintenance equipment.
–Warehouses and office spaces.

These leases are recognized, measured and presented in accordance to IFRS 16 “Leases”, following the guidelines described below.
Accounting by the lessee
The Company recognizes a right-of-use asset and a lease liability at the commencement date of each lease contract that grants the right to control the use of an identified asset during a period of time. The commencement date is the date in which the lessor makes an underlying asset available for use by the lessee.
The Company applied exemptions for leases with a duration lower than 12 months, with a value lower than thirty thousand U.S. dollars and/or with clauses related to variable payments. These leases have been considered as short-term leases and, accordingly, no right-of-use asset or lease liability have been recognized.
At initial recognition, the right-of-use asset is measured considering:
–The value of the initial measurement of the lease liability;
–Any lease payments made at or before the commencement date, less any lease incentives; and
–Any initial direct costs incurred by the lessee.

After initial recognition, the right-of-use assets are measured at cost, less any accumulated depreciation and/or impairment losses, and adjusted for any re-measurement of the lease liability.

Depreciation of the right-of-use asset is calculated using the straight-line method over the estimated duration of the lease contract, as follows:
Land                            1-30 years
Buildings and facilities                    1-25 years
Machinery                        1-13 years

If the lease transfers ownership of the underlying asset to the Company by the end of the lease term, or if the cost of the right-of-use asset reflects that the Company will exercise a purchase option, the Company depreciates the right-of-use asset from the commencement date to the end of the useful life of the underlying asset. Otherwise, the Company depreciates the right-of-use asset from the commencement date to the earlier of the end of the useful life of the right-of-use asset or the end of the lease term.
Accounting by the lessor
When the Company is acting as a lessor, each of its leases is classified as either operating or finance lease:
–Leases where a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases.
–Leases where all substantial risks and rewards of ownership are transferred by the lessor to the lessee are classified as finance leases.

(e)Intangible assets
(1)    Information system projects
Generally, costs associated with developing or maintaining computer software programs are recognized as an expense as incurred. However, costs directly related to the acquisition and implementation of information systems are recognized as intangible assets if they have a probable economic benefit exceeding the cost beyond one year and comply with the recognition criteria of IAS 38.
Information system projects recognized as assets are amortized using the straight-line method over their useful lives, not exceeding a period of 3 years. Amortization charges are included in cost of sales, selling, general and administrative expenses.
(2)    Mining assets
Mining assets include:
(a)Mining licenses acquired;
(b)Capitalized exploration and evaluation costs, reclassified from exploration and evaluation costs (see note 4 (e) 3); and
(c)Capitalized developmental stripping costs (see note 4 (u)).
Mining licenses were recognized as separate intangible assets upon the acquisition of the investment in Mexico and in Usiminas and comprise the right to exploit the mines and are recognized at its fair value at acquisition date less accumulated amortization.
Mexico’s mining concessions were granted for a 50-year period; following the expiration of the initial concession term, the concessions are renewable for an additional 50-year term in accordance with, and subject to the procedures set forth in, applicable Mexican mining law.
Usiminas’ mining concessions were granted for an indefinite period and until complete depletion of mineral reserves and are subject to the procedures set forth in applicable Brazilian mining law.
Amortization charge is calculated by using the unit-of-production method, on the basis of actual mineral extracted in each period compared to the estimated mineral reserves, and is included in cost of sales. Any change in the estimation of reserves is accounted for prospectively. The resulting amortization rate for the years ended December 31, 2024, 2023 and 2022, is approximately 19%, 13% and 12% per year, respectively.
Considering that there are no concrete development plans in the short term and for production feasibility in certain areas of the mining concessions held by Las Encinas S.A. de C.V., the Company decided to recognize an impairment charge over these assets of $32.4 million as of December 31,2024. As of December 31, 2023, the Company has already recognized an impairment charge over these assets held by Las Encinas S.A. de C.V. for an amount of $42.3 million.

(3)Exploration and evaluation costs
Exploration and evaluation activities involve the search for iron ore resources, the determination of technical feasibility and the assessment of commercial viability of an identified resource.
Exploration and evaluation costs are measured at cost. Costs directly associated with exploration and evaluation activities are capitalized as intangible assets until the determination of reserves is evaluated. The costs associated to the acquisition of machinery and equipment are recognized as property, plant and equipment. If it is determined that commercial discovery has been achieved, costs incurred are reclassified into Mining assets and amortization starts once production begins.
Exploration costs are tested for impairment whenever there are indicators that impairment exists. Indicators of impairment include, but are not limited to:
–Rights to explore in an area have expired or will expire in the near future without renewal;
–No further exploration and evaluation is planned or budgeted;
–A decision to discontinue exploration and evaluation in an area because of the absence of commercial reserves; and
–Sufficient data exists to indicate that the book value will not be fully recovered from future development and production.

When analyzing the existence of impairment indicators, the exploration and evaluation areas from the mining units will be evaluated.
(4)    Goodwill
Goodwill represents the excess of the acquisition cost over the fair value of Ternium's participation in acquired companies' net assets at the acquisition date. Under IAS 36, goodwill is considered to have an indefinite life and not amortized, but is subject to annual impairment testing.
Goodwill is allocated to Cash-generating units ("CGU") for the purpose of impairment testing. The allocation is made to those cash-generating units expected to benefit from the business combination which generated the goodwill being tested. The impairment losses on goodwill cannot be reversed.
As of December 31, 2024 and 2023, the carrying amount of goodwill allocated to the Mexico CGUs was $662.3 million, of which $619.8 million corresponds to Steel Mexico CGU and $42.5 million to Mining Mexico CGU.
(5)    Research and development
Research expenditures are recognized as expenses as incurred. Development costs are recorded as cost of sales in the income statement as incurred because they do not fulfill the criteria for capitalization. Research and development expenditures for the years ended December 31, 2024, 2023 and 2022 totaled $23.8 million, $19.0 million and $16.3 million, respectively.

(6)    Customer relationships acquired in a business combination
As of December 31, 2024, Ternium has no customer relationships acquired in a business combination recognized in its consolidated financial statements.

(7)    Trademarks acquired in a business combination
Trademarks are amortized using the straight-line method over a useful life of between 5 to 10 years.
(f)    Impairment
Assets that have an indefinite useful life (including goodwill) are not subject to amortization and are tested annually for impairment or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Assets that are subject to amortization and investments in affiliates are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for the amount by which the asset's carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset's fair value less cost to sell and the value in use.
To carry out these tests, assets are grouped at the lowest levels for which there are separately identifiable cash flows (each, a CGU). When evaluating long-lived assets for potential impairment, the Company estimates the recoverable amount based on the higher of the CGU’s fair value less costs to sell and its value in use. The value in use of each CGU is determined on the basis of the present value of net future cash flows which will be generated by the assets tested.
Determining the present value of future cash flows involves highly sensitive estimates and assumptions specific to the nature of each CGU's activities, including estimates and assumptions relating to amount and timing of projected future cash flows. Application of the discounted cash flow (DCF) method to determine the value in use of a CGU begins with a forecast of all expected future net cash flows. Significant assumptions considered in forecasts include the gross domestic product (GDP) growth rates of the country under study and their correlation with steel demand, changes in the growth rate for the perpetuity rate, changes in steel prices, changes in certain significant raw material costs and changes in discount rates.
Ternium uses, for the steel segment impairment tests, cash flow projections over a five-year period based on past performance and expectations of market development; for the subsequent years beyond the five-year period, a terminal value was calculated based on perpetuity. The growth rate used for the perpetuity rate is of 2.19%. This rate does not exceed the average long-term growth rate for the relevant markets. In the case of the mining segment and the mining activity developed by Usiminas, cash flow projections are prepared until the mines are fully depleted and are based on past performance and expectations of market development.
Cash flows are discounted at rates that reflect specific country and currency risks associated with the cash flow projections. The discount rates used are based on the weighted average cost of capital (WACC), which is considered to be a good indicator of cost of capital.

Considering the uncertainty of the future evolution of the macroeconomic and financial situation in Argentina and the reduction of the operating margin as of December 31, 2024, the Company decided to assess the recoverability of its investments in Argentina, resulting in no impairment charges to be recognized. As of December 31, 2024, the post-tax discount rate used to test the investment in Argentine subsidiaries for impairment was 14.0%. The recoverable value of CGU Argentina amounted to $1.7 billion as of December 31, 2024. The Company estimates that an increase higher than 0.5% in the discount rate or a decrease higher than 5.0% in the operating income before amortization and depreciation per ton may result in the recognition of an impairment charge in the CGU Argentina.

As of December 31, 2022, the Company recognized an impairment charge of $99.0 million over the property, plant and equipment in the Brazil CGU. As of December 31, 2023, Management assessed the business situation as of such date and concluded that the recovery of impairment indicators was not significantly enough and that there were no significant positive events to proceed with a reversal of previously recognized impairment charges. Considering the uncertainty of the future evolution of the macroeconomic situation in Brazil, mainly the devaluation of the Brazilian reais, and the reduction of the volume of sales and operating margin as of December 31, 2024, the Company decided to assess the recoverability of its investments in Brazil, resulting in no impairment charges to be recognized. As of December 31, 2024, the post-tax discount rate used to test the investment in Brazilian subsidiaries for impairment was 10.3%.

As of September 30, 2022, the Company recognized an impairment charge of $120.4 million over the investment in Usiminas. On July 3, 2023, the Company acquired an additional participation in Usiminas and started the full consolidation of assets and liabilities of Usiminas (see note 3). As of December 31, 2023, no impairment triggers were detected and, consequently, no impairment test was prepared. Considering the uncertainty of the future evolution of the macroeconomic situation in Brazil, mainly the devaluation of the Brazilian reais, and the decrease of the market value of the shares as of December 31, 2024, the Company decided to assess the recoverability of its investments in Usiminas, resulting in no impairment charges to be recognized. As of December 31, 2024, the post-tax discount rate used to test the investment in Brazilian subsidiaries for impairment was 10.3%.

In the case of the Steel Mexico CGU, considering that there is a value registered for goodwill, the Company performed the mandatory impairment test over goodwill, resulting in no impairment charges to be recognized. Also, in the case of the Mining Mexico CGU and considering the registered goodwill, the Company performed the mandatory impairment test over goodwill, resulting in no impairment charges to be recognized. As of December 31, 2024, the post-tax discount rate used to test the recoverability of the goodwill in the Steel and Mining Mexico CGUs for impairment was 12.4% (as of December 31, 2023, 12.1%).

During the years 2024, 2023 and 2022, no impairment provisions were recorded in connection with assets that have an indefinite useful life (including goodwill) in the Company’s CGUs.

(g)    Other investments
Other investments consist primarily of investments in financial debt instruments and equity investments where the Company holds a minor equity interest and does not exert significant influence.

All purchases and sales of investments are recognized on the settlement date, which is not significantly different from the trade date, which is the date that Ternium commits to purchase or sell the investment.
Income from financial instruments at fair value through profit or loss is recognized in Other financial income (expenses), net in the consolidated income statement. The fair value of quoted investments is based on current bid prices. If the market for a financial investment is not active or the securities are not listed, the Company estimates the fair value by using standard valuation techniques. Dividends from investments in equity instruments are recognized in the income statement when the Company's right to receive payments is established.
Certain fixed income financial instruments purchased by the Company have been categorized as at fair value through other comprehensive income. The results of these financial investments are recognized in Finance Income in the Consolidated Income Statement using the effective interest method. Unrealized gains and losses other than impairment and foreign exchange results are recognized in Other comprehensive income. On maturity or disposal, net gain and losses previously deferred in Other comprehensive income are recognized in Finance Income in the Consolidated Income Statement.
(h)Inventories
Inventories are stated at the lower of cost (calculated using the first-in-first-out "FIFO" method) or net realizable value. The cost of finished goods and goods in process comprises raw materials, direct labor, depreciation, other direct costs and related production overhead costs. It excludes borrowing costs. Goods acquired in transit at year end are valued at supplier's invoice cost.
The cost of iron ore produced in our mines comprises all direct costs necessary to extract and convert stockpiled inventories into raw materials, including production stripping costs, depreciation of fixed assets related to the mining activity and amortization of mining assets for those mines under production.
The Company assesses the recoverability of its inventories considering their selling prices, if the inventories are damaged, or if they have become wholly or partially obsolete.
(i)Trade receivables and other receivables
Trade and other receivables are recognized initially at fair value, generally the original invoice amount. The Company applies the IFRS 9 simplified approach to measuring expected credit losses which uses a lifetime expected loss allowance for all trade receivables. To measure the expected credit losses, trade receivables are grouped based on shared credit risk characteristics and the days past due. The Company keeps an allowance for trade receivables, recorded in an asset account to offset the trade receivables in an amount estimated sufficient to cover the losses resulting from the impossibility for the debtors to cancel the amounts owed. This allowance for trade receivables is recorded with a charge to selling expenses.
Judicial deposits are those made in a bank account, in connection with legal proceedings, in Brazilian currency and monetarily restated to ensure the settlement of potential future liabilities. Some judicial deposits that are linked to taxes payable in installments are presented at their net amount.

(j)    Cash and cash equivalents

Cash and cash equivalents and highly liquid short-term securities are carried at fair market value or at a historical cost which approximates fair market value.

For purposes of the cash flow statement, cash and cash equivalents comprise cash, bank current accounts and short-term highly liquid investments (original maturity of three months or less at date of acquisition) and overdrafts.

In the consolidated statement of financial position, bank overdrafts are included in borrowings within current liabilities.

(k)     Assets (disposal groups) classified as held for sale

Assets (disposal groups) are classified as assets held for sale, complying with the recognition criteria of IFRS 5, and stated at the lower of carrying amount and fair value less cost to sell if their carrying amount is recovered principally through a sale transaction rather than through continuing use.

The carrying value of assets classified as held for sale, as of December 31, 2024 and 2023 totals $7.3 million and $6.7 million, respectively, which corresponds principally to land and other real estate items. Sale is expected to be completed within a one-year period.

(l)     Borrowings

Borrowings, including bonds and debentures issued by Usiminas, are recognized initially for an amount equal to the net proceeds received. In subsequent periods, borrowings, including bonds and debentures, are stated at amortized cost following the effective interest method.

(m)    Lease liabilities

The lease liability is initially measured at the present value of the lease payments that are not paid at such date, including the following concepts:
–Fixed payments, less any lease incentives receivable;
– Variable lease payments that depend on an index or rate, initially measured using the index or rate as of the commencement date;
– Amounts expected to be payable by the lessee under residual value guarantees;
– The exercise price of a purchase option if the lessee is reasonably certain to exercise that option; and
– Payments of penalties for terminating the lease, if the lease term reflects the lessee exercising an option to terminate the lease.

Variable lease liabilities with payments dependent on external factors, such as minimum volumes sold or used, are not included in the initial measurement of the lease liabilities and such payments are recognized directly in profit and loss.
Lease payments are discounted using incremental borrowing rates for the location and currency of each lease contract or, if available, the rate implicit in the lease contract.
The finance cost is charged to profit or loss over the lease period to produce a constant periodic rate of interest on the remaining balance of the liability for each period.

The lease term determined by the Company comprises:
– Non-cancelable period of lease contracts;
– Periods covered by an option to extend the lease if the lessee is reasonably certain to exercise that option; and
– Periods covered by an option to terminate the lease if the lessee is reasonably certain not to exercise that option.

After the commencement date, the Company measures the lease liability by:
– Increasing the carrying amount to reflect interest on the lease liability;
– Reducing the carrying amount to reflect lease payments made; and
– Re-measuring the carrying amount to reflect any reassessment or lease modifications.

(n)    Income taxes - current and deferred
The current income tax charge is calculated on the basis of the tax laws in force in the countries in which Ternium and its subsidiaries operate. Management evaluates positions taken in tax returns with respect to situations in which applicable tax regulation could be subject to interpretation. A liability is recorded for tax benefits that were taken in the applicable tax return but have not been recognized for financial reporting.
Deferred income taxes are calculated using the liability method on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the financial statements. Deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting, nor taxable profit or loss. The principal temporary differences arise on fixed assets, intangible assets, inventories valuation and provisions for pensions. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the period when the asset is realized or the liability is settled, based on tax rates and tax laws that have been enacted or substantially enacted at year end. Under IFRS, deferred income tax assets (liabilities) are classified as non-current assets (liabilities).
Deferred tax assets are recognized to the extent it is probable that future taxable income will be available to offset temporary differences.
Deferred income tax is provided on temporary differences arising on investments in subsidiaries and associated companies, except where the timing of the reversal of the temporary difference is controlled by the Company and it is probable that the temporary difference will not reverse in the foreseeable future.
Deferred tax assets and liabilities are re-estimated if tax rates change. These amounts are charged or credited to the consolidated income statement or to the item “Other comprehensive income for the year” in the consolidated statement of comprehensive income, depending on the account to which the original amount was charged or credited.

4.    ACCOUNTING POLICIES (continued)
A defined benefit plan is a pension plan that defines an amount of pension benefit that an employee will receive on retirement, usually dependent on one or more factors such as age, years of service and compensation.
The liability recognized in the statement of financial position in respect of defined benefit pension plans is the present value of the defined benefit obligation at the end of the reporting period less the fair value of plan assets. The defined benefit obligation is calculated annually (at year end) by independent actuaries using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid, and that have terms to maturity approximating to the terms of the related pension obligation. In countries where there is no deep market in such bonds, the market rates on government bonds are used.
Actuarial gains and losses arising from experience adjustments and changes in actuarial assumptions are charged or credited to equity in other comprehensive income in the period in which they arise. Past-service costs are recognized immediately in income. For defined benefit plans, net defined benefit liability/asset is calculated based on the surplus or deficit derived by the difference between the defined benefit obligations less plan assets.

For defined contribution plans, the Company pays contributions to publicly or privately administered pension insurance plans on a mandatory, contractual or voluntary basis. The Company has no further payment obligations once the contributions have been paid. The contributions are recognized as employee benefit expense when they are due. Prepaid contributions are recognized as an asset to the extent that a cash refund or a reduction in the future payments is available.

Mexico
Ternium Mexico has defined benefit and defined contribution plans.
The valuation of the liabilities for the defined benefit employee retirement plans (pensions and seniority premiums) covers all employees and is based primarily on their years of service, their present age and their remuneration at the date of retirement. The cost of the employee retirement plans (pension, health-care expenses and seniority premiums) is recognized as an expense in the year in which services are rendered in accordance with actuarial studies made by independent actuaries. The formal retirement plans are congruent with and complementary to the retirement benefits established by the Mexican Institute of Social Security. Additionally, the Company has established a plan to cover health-care expenses of retired employees. The Company has established a commitment for the payment of pensions and seniority premiums, as well as for health-care expenses.
The defined contribution plans provide a benefit equivalent to the capital accumulated with the company's contributions, which are provided as a match of employees' contributions to the plan. The plan provides vested rights according to the years of service and the cause of retirement.

Ternium Argentina implemented an unfunded defined benefit employee retirement plan for certain senior officers.

This unfunded plan provides defined benefits based on years of service and final average salary.
Brazil
Usiminas operates various post-employment schemes, including defined benefit pension plans, defined/variable contribution pension plans and a post-retirement healthcare plan. The retirement plans offer to employees’ supplementary retirement and pension benefits and are managed by Previdência Usiminas, which in line with the applicable legislation, has as its main purpose the management and running of private pension plans.

Usiminas has different defined benefit pension plans:
1) Benefit plan 1 (PB1), defined benefit plan, closed for new enrolments since November 1996.
2) Defined benefit plan (PBD), defined benefit plan, closed for new enrolments since December 2000; the beneficiaries of this plan are also entitled to self-funded retirement plan, vesting, redemption, and portability.

The liability recognized in the balance sheet in respect of defined benefit pension plans is the present value of the defined benefit obligation at the balance sheet date minus the market value of plan assets, adjusted for: (i) actuarial gains and losses; (ii) rules to determine the asset ceiling; and (iii) minimum funding requirements.

Usiminas has taken out debts in connection with the minimum requirements for payment of contributions, for the purpose of covering the gap in relation to the services already received. In the event of non-recoverable surplus, the debts taken are recognized as an additional liability in the computation of net actuarial liabilities.

The PBD plan debit balance is determined at the end of each year, based on a direct actuarial revaluation. During the subsequent year, the liability is adjusted by the monthly surplus or deficit determined in the PBD plan and by the amount of payments falling due in the period. The debt balance should be repaid in 148 installments.

Also, Usiminas has different defined contribution pension plans:

3) Benefit plan 2 (USIPREV), variable contribution benefit plan, operating since August 1998, provides post-employment benefits to the employees of the sponsor companies. Currently, this is the only plan accepting new enrolments.

4) COSIPREV, defined contribution plan has been closed for new enrolments since April 30, 2009. For this defined contribution plan (COSIPREV), Usiminas pays contributions to a private pension entity on compulsory, contractual or voluntary bases. The contributions are recognized as finance costs in the period in which they are due. The entity has no further payment obligations once the contributions have been paid.

4.    ACCOUNTING POLICIES (continued)

USIPREV and COSIPREV plans have a Pension Fund formed from members’ account balances not used in benefit payouts. As provided for in the plans’ regulations, this Fund may be used to cover the cost of these plans in the future.

In addition, Usiminas has in place a post-retirement healthcare plan:

(a) CoSaúde, post-retirement healthcare benefits discontinued on November 30, 2021, with the subsequent restructuring of group plans to be offered to former beneficiaries, in compliance with the legal clauses and conditions.
(b) Saúde Usiminas, healthcare plan, which opened for enrolments to all employees and retirees in 2010 and was extinguished as of December 31, 2023, being replaced with two new plans: Usiexato and Usiflex. These two new plans provide with two different methods of payment to the members of the plans: a mixed method, with the Company offering the option of bearing 100% of the monthly fee for active employees until the termination of the labor contracts, or a contributory method, which allows the continuation of the healthcare services after resignation or retirement of the employees.

(2)Termination benefits
Termination benefits are payable when employment is terminated before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. The Company recognizes termination benefits when it is demonstrably committed to either: (i) terminating the employment of current employees according to a detailed formal plan without possibility of withdrawal or (ii) providing termination benefits as a result of an offer made to encourage voluntary redundancy.
(3)    Other compensation obligations
Employee entitlements to annual leave and long-service leave are accrued as earned.
During 2007, Ternium launched an incentive retention program (the "Program") applicable to certain senior officers and employees of the Company, who will be granted a number of Units throughout the duration of the Program. The value of each of these Units is based on Ternium's shareholders' equity (excluding non-controlling interest). Also, the beneficiaries of the Program are entitled to receive cash amounts based on (i) the amount of dividend payments made by Ternium to its shareholders, and (ii) the number of Units held by each beneficiary to the Program. Units vest ratably over a period of four years and will be redeemed by the Company ten years after grant date, with the option of an early redemption at seven years after grant date. From 2018 units were vest ratably over the same period and will be mandatorily redeemed by the Company seven years after grant date. As the cash payment of the benefit is tied to the book value of the shares, and not to their market value, Ternium valued this long-term incentive program as a long term benefit plan as classified in IAS 19.
As of December 31, 2024 and 2023, the outstanding liability corresponding to the Program amounts to $86.0 million and $90.1 million, respectively. The total value of the units granted to date under the program, considering the number of units and the book value per share as of December 31, 2024 and 2023, is $94.0 million and $96.6 million, respectively.
Under Mexican law, Ternium's subsidiaries are required to pay their employees an annual benefit which is determined as a percentage of taxable profit for the year.

4.    ACCOUNTING POLICIES (continued)
(4)    Social security contributions
Social security laws in force in the countries in which the Company operates provide for pension benefits to be paid to retired employees from government pension plans and/or private fund managed plans to which employees may elect to contribute. As stipulated by the respective laws, Ternium Argentina and Ternium Mexico make monthly contributions calculated based on each employee's salary to fund such plans. The related amounts are expensed as incurred. No additional liabilities exist once the contributions are paid.
(p)    Provisions
Ternium has certain contingencies with respect to existing or potential claims, lawsuits and other proceedings. Unless otherwise specified, provisions are recognized when Ternium has a present legal or constructive obligation as a result of past events, it is probable that an outflow of resources will be required to settle the obligation, and the amount can be reliable estimated. Generally, accruals are based on developments to date, Ternium's estimates of the outcomes of these matters and the advice of Ternium's legal advisors. The Company also discloses the contingency in circumstances where management concludes no loss is probable or reasonably estimable but it is reasonably possible that a loss may be incurred.

(q)    Trade payables
Trade payables are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method.
(r)    Revenue recognition and other income
Revenue is recognized at a point of time from sales to direct customers upon the satisfaction of performance obligations, which occurs when control of the goods transfers to the customer and the customer obtains the benefits from the goods, the potential cash flows and the transaction price can be measured reliably, and it is probable that the Company will collect the consideration in connection with the exchange of the goods. The control over the goods is obtained by the customer depending on when the goods are made available to the shipper or the customer takes possession of the goods, depending on the delivery terms. The Company considers that it has completed its performance obligations when the goods are delivered to its customers or to a shipper who will transport the goods to its customers. The revenue recognized by the Company is measured at the transaction price of the consideration received or receivable to which the Company is entitled to, reduced by estimated returns and other customer credits, such as discounts and volume rebates, based on the expected value to be realized and after eliminating sales within the group.
Usiminas Mecánica S.A., one of Usiminas’ subsidiaries, uses the percentage-of-completion (POC) method to account for the revenue from orders in progress sold at fixed prices. The use of the POC method requires Management to estimate the services performed up to the balance sheet date as a proportion of the total services to be performed.
Interest income is recognized on an effective yield basis.
(s)    Borrowing Costs
General and specific borrowing costs that are directly attributable to the acquisition, construction or production of a qualifying asset are capitalized during the period of time that is required to complete and prepare the asset for its intended use or sale. Qualifying assets are assets that necessarily take a substantial period of time to get ready for their intended use or sale.

4.    ACCOUNTING POLICIES (continued)
Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs eligible for capitalization.
Other borrowing costs are expensed in the period in which they are incurred.
The amount of borrowing costs that Ternium capitalized during a period will not exceed the amount of borrowing costs incurred during that period. As of December 31, 2024, 2023 and 2022, the capitalized borrowing costs were nil, nil and $0.4 million, respectively.
(t)    Cost of sales, selling, general and administrative expenses
Cost of sales and expenses are recognized in the income statement on the accrual basis of accounting.
Commissions, freight and other selling expenses, including shipping and handling costs, are recorded in Selling, general and administrative expenses in the Consolidated Income Statement.
(u)    Stripping costs
Stripping costs are the costs associated with the removal of overburden and other waste materials and can be incurred before the mining production commences (“development stripping”) or during the production stage (“production stripping”).
Development stripping costs that contribute to the future economic benefits of mining operations are capitalized as intangible assets (Mining assets). Production stripping costs which are part of on-going activities are included in the cost of the inventory produced (that is extracted) at each mine during the period in which they are incurred.
Capitalization of development stripping costs finishes when the commercial production of the mine commences. At that time, all development stripping costs are presented within Mining assets and depreciated on a unit-of-production basis. It is considered that commercial production begins when the production stage of mining operations begins and continues throughout the life of a mine.
(v)    Mining development costs
Mining development costs are the costs associated to the activities related to the establishment of access to the mineral reserve and other preparations for commercial production. These activities often continue during production.
Development expenditures are capitalized and classified as Work in progress. On completion of development, all assets included in Work in progress are individually reclassified to the appropriate category of property, plant and equipment and depreciated accordingly.
(w)    Asset retirement obligations
Ternium records asset retirement obligations (“ARO”) initially at the fair value of the legal or constructive obligation in the period in which it is incurred and capitalizes the ARO by increasing the carrying amount of property, plant and equipment. The fair value of the obligation is determined as the discounted value of the expected future cash flows and is included in Provisions. The liability is accreted to its present value through net financing cost and the capitalized cost is depreciated based in the unit of production method.

4.    ACCOUNTING POLICIES (continued)
(x)    Earnings per share
Earnings per share are calculated by dividing the net income attributable to shareholders by the daily weighted average number of ordinary shares issued during the year, excluding the average number of shares of the parent Company held by the Group. There are no dilutive securities for the periods presented.
(y)    Derivative financial instruments and hedging activities
Ternium designates certain derivatives as hedges of a particular risk associated with a recognized asset or liability or a highly probable forecast transaction. These transactions are classified as cash flow hedges (mainly interest rate swaps, collars, currency forward contracts on highly probable forecast transactions and commodities contracts). The effective portion of the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in OCI. Amounts accumulated in OCI are recognized in the income statement in the same period as any offsetting losses and gains on the hedged item. The gain or loss relating to the ineffective portion is recognized immediately in the income statement. The fair value of Ternium derivative financial instruments (asset or liability) continues to be reflected in the statement of financial position.
For transactions designated and qualifying for hedge accounting, Ternium documents the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedge transactions. As of December 31, 2024 and 2023, the effective portion of designated cash flow hedges (net of taxes) amounted to ($37.3) million and $15.9 million, respectively, and were included under "changes in the fair value of derivatives classified as cash flow hedges" line item in the statement of comprehensive income (see Note 27 (a)).
More information about accounting for derivative financial instruments and hedging activities is included in Note 29 "Financial risk management".
(z)    Treasury shares
Acquisitions of treasury shares are recorded at acquisition cost, deducted from equity until disposal. The gains and losses on disposal of treasury shares are recognized under "Reserves" in the consolidated statement of financial position.
(aa)    Cash flow
The consolidated statements of cash flows have been prepared using the indirect method and contain the use of the following expressions and their respective meanings:
a)    Operating activities: activities that constitute ordinary Group revenues, as well as other activities that cannot be qualified as investing or financing.
b)    Investing activities: acquisition, sale or disposal by other means of assets in the long-term and other investments not included in cash and cash equivalents.
c)    Financing activities: activities that generate changes in the size and composition of net equity and liabilities that do not form part of operating activities.

4.    ACCOUNTING POLICIES (continued)
(bb)    Critical Accounting Estimates
The preparation of financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and the related disclosure of contingent assets and liabilities. Estimates and judgments are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Management makes estimates and assumptions concerning the future. Actual results may differ significantly from these estimates under different assumptions or conditions.
The principal estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are addressed below.
(1) Goodwill impairment test
Assessment of the recoverability of the carrying value of goodwill requires significant judgment. Management evaluates goodwill allocated to the operating units for impairment on an annual basis or whenever there is an impairment indicator.
Goodwill is tested at the level of the CGUs. Impairment testing of the CGUs is carried out and the value in use determined in accordance with the accounting policy stated in Note 4(f). The discount rates used for these tests are based on Ternium's weighted average cost of capital adjusted for specific country and currency risks associated with the cash flow projections. The post-tax discount rate used as of December 31, 2024 was 12.38% and no impairment charge resulted from the impairment test performed. See notes 4(f) and 4(e)(4).
(2)Income taxes
Management calculates current and deferred income taxes according to the tax laws applicable to each subsidiary in the countries in which such subsidiaries operate. However, due to uncertain tax positions, certain adjustments necessary to determine the income tax provision are finalized only after the balance sheet is issued. In cases in which the final tax outcome is different from the amounts that were initially recorded, such differences will impact the income tax and deferred tax provisions in the period in which such determination is made.
Also, when assessing the recoverability of tax assets, management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies.
(3)    Loss contingencies
Ternium is subject to various claims, lawsuits and other legal proceedings that arise in the ordinary course of business, including customer claims in which a third party is seeking reimbursement or indemnity. The Company's liability with respect to such claims, uncertain tax positions, lawsuits and other legal proceedings cannot be estimated with certainty. Periodically, management reviews the status of each significant matter and assesses potential financial exposure. If the potential loss from the claim or proceeding is considered probable and the amount can be reasonably estimated, a liability is recorded. Management estimates the amount of such liability based on the information available and the assumptions and methods it has concluded are appropriate, in accordance with the provisions of IFRS. Accruals for such contingencies reflect a reasonable estimate of the losses to be incurred based on information available, including the relevant litigation or settlement strategy, as of the date of preparation of these financial statements.

Consolidated Financial Statements as of December 31, 2024 and 2023
and for the years ended December 31, 2024, 2023 and 2022

4.    ACCOUNTING POLICIES (continued)
As additional information becomes available, management will reassess its evaluation of the pending claims, lawsuits and other proceedings and revise its estimates. The loss contingencies provision amounts to $962.8 million and $839.9 million as of December 31, 2024 and 2023, respectively.
(4)    Useful Lives and Impairment of Property, Plant and Equipment and Other Long-lived Assets
In determining useful lives, management considered, among others, the following factors: age, operating condition and level of usage and maintenance. Management conducted visual inspections for the purpose of (i) determining whether the current conditions of such assets are consistent with normal conditions of assets of similar age; (ii) confirming that the operating conditions and levels of usage of such assets are adequate and consistent with their design; (iii) establishing obsolescence levels and (iv) estimating life expectancy, all of which were used in determining useful lives. Management believes, however, that it is possible that the periods of economic utilization of property, plant and equipment may be different than the useful lives so determined. Furthermore, management believes that this accounting policy involves a critical accounting estimate because it is subject to change from period to period as a result of variations in economic conditions and business performance.
When assessing whether an impairment indicator may exist, the Company evaluates both internal and external sources of information, such as the following:
–whether significant changes with an adverse effect on the entity have taken place during the period, or will take place in the near future, in the technological, market, economic or legal environment in which the entity operates or in the market to which an asset is dedicated;
–whether market interest rates or other market rates of return on investments have increased during the period, and those increases are likely to affect the discount rate used in calculating an asset's value in use and decrease the asset's recoverable amount materially;
–whether the carrying amount of the net assets of the entity is more than its market capitalization;
–whether evidence is available of obsolescence or physical damage of an asset.
–whether significant changes with an adverse effect on the entity have taken place during the period, or are expected to take place in the near future, in the extent to which, or manner in which, an asset is used or is expected to be used. These changes include the asset becoming idle, plans to discontinue or restructure the operation to which an asset belongs, plans to dispose of an asset before the previously expected date, and reassessing the useful life of an asset as finite rather than indefinite; and
–whether evidence is available from internal reporting that indicates that the economic performance of an asset is, or will be, worse than expected.

(5)    Post-employment obligation estimates
The Company estimates at each year-end the provision necessary to meet its post-employment obligations in accordance with the advice from independent actuaries. The calculation of post-employment and other employee obligations requires the application of various assumptions. The main assumptions for post-employment and other employee obligations include discount rates, compensation growth rates, pension growth rates and life expectancy.  Changes in the assumptions could give rise to adjustments in the results and liabilities recorded and might have an impact on the post-employment and other employee obligations recognized in the future.

4.    ACCOUNTING POLICIES (continued)
(6)    Business combinations
The recognition of business combinations requires the excess of the purchase price of acquisitions over the net book value of assets acquired to be allocated to the assets and liabilities of the acquired entity. The Company makes judgments and estimates in relation to the fair value of assets acquired and liabilities assumed, including estimation of cash flow projections with significant assumptions related to revenue forecasts, EBITDA margins, capital expenditures, discount rate and estimation of loss probability for the contingencies assumed. If any unallocated portion is positive, it is recognized as goodwill, and if negative, it is recognized in the income statement. See further information in note 3.

(7)    Taxation

At year end, the Company assesses the sufficiency of future taxable income to utilize the recognized deferred tax assets. The Company uses projections of future taxable income to assess the probability that the deferred tax assets will be realized. Management applied significant judgment in assessing the recoverability of deferred tax assets predicting historical profitability, projected future taxable profit, including assumptions related to revenue forecast and EBITDA margins.

(cc) General sustainability matters and climate change

Ternium subscribed to the United Nations Global Compact in October 2019 and has been reporting its contribution to the Sustainable Development Goals since then. The Company has established policies, procedures, and plans that cover various ESG topics, including climate change, environmental management, health and safety management, human resources management, community relations, supply chain management, and principles of behavior and corporate governance.

Climate Change

The Company has established a governance system to address climate change at various levels. The Vice-Chairman of the Board was appointed to report on the evolution of Ternium's climate change strategy to the Board of Directors on a quarterly basis. At the management level, a decarbonization committee, chaired by the CEO, periodically reviews performance indicators, progress on decarbonization projects, and updates on the context, such as regulatory changes, market shifts, and trends.

The Company has also incorporated climate-related risks into its risk management policy and reviews both transition risks and physical risks. For example, during 2021 and 2022, the Company engaged an external consultant to assess the exposure of its assets and provide a conclusion on the level of risk, considering the established preventive measures. The analysis examined exposure and vulnerability to five types of events: pluvial flooding, tropical cyclones, landslides, forest fires, and droughts. The analysis concluded that Ternium's facilities do not present significant risk, given the level of exposure and the mitigation measures implemented by the Company under the scenarios and time periods analyzed. Management assessed that there have been no changes since this analysis was performed.

In 2024, the Company updated its decarbonization target. The new target aims for a 15% reduction in the emission intensity rate per ton of hot-rolled steel equivalent by 2030, compared to a 2023 baseline. This target includes Scope 1, 2, and 3 (Categories 1 and 10) and is measured using the GHG Protocol methodology.

Consolidated Financial Statements as of December 31, 2024 and 2023
and for the years ended December 31, 2024, 2023 and 2022

4.    ACCOUNTING POLICIES (continued)
The Company’s strategy to achieve this 2030 reduction target includes prioritizing low-emission production technologies, increasing the use of renewable sources in the energy mix, improving industrial performance, executing energy efficiency initiatives, expanding carbon capture and usage capacity, and increasing the participation of scrap in the metallic mix. Since these projects take several years to execute and complete, the Company anticipates improvements in its intensity rate after 2025. The Company is also considering several initiatives to continue its journey after 2030, including the possibility of carbon storage, the use of biofuels, and hydrogen as reducing agents, as it aims for carbon neutrality, if and when economically and technologically feasible.

In general, the decarbonization of the steel industry will require significant long-term investments, conditioned by technological innovation, government regulations, capital availability for decarbonization projects, and cooperation within the value chain. Factors such as access to abundant and affordable clean energy, appropriate energy infrastructure, local and global regulations that ensure fair trade and carbon capture storage, access to sustainable finance for low-emission steel-making technologies, and changes in consumer behavior will be key to the development of solutions and outcomes in the coming decades.

Given that Ternium’s climate-change-related decarbonization plans span many years and are subject to significant uncertainty, as described above, they have not been included as part of the assumptions used to calculate future cash flows of the recoverable amount of the company’s CGUs, except for those plans that are already approved or in process. Estimates and assumptions related to the impairment test for long-lived assets and goodwill, useful lives of assets, capital and research and development expenditures, inventory valuation, recovery of deferred tax assets and provisions, and contingent liabilities are based on available information and government regulations in place as of December 31, 2024, as well as the companies already approved or in-process investment plans.

Environmental Management

Given the strong relationship between industrial activity and environmental performance, the Company unified the areas of environment and health and safety in 2021. Currently, these topics fall under the responsibility of the Chief Environment, Health, and Safety Officer, appointed in 2023. Environmental performance is analyzed monthly in Environmental, Health, and Safety meetings with executive officers. Furthermore, environmental issues are included in regular meetings on industrial and business performance reviews held both locally and at a corporate level. Finally, the Board of Directors is informed of events related to environmental issues that could impact nearby communities or Ternium’s reputation and operations. In 2023, Ternium's CEO approved an update to Ternium’s environmental and energy policy, which provides the framework to which the entire company is expected to adhere. The main updates were: inclusion of a decarbonization roadmap and the ambition of achieving carbon neutrality, subject to technological feasibility and market conditions; introduction of the concept of the circular economy, expanding the scope of efficient use of natural resources; specific mention of minimizing air emissions at the sites where we operate, optimizing water use, and maximizing its reuse; inclusion of biodiversity protection in the areas where we operate and compensation for impacts; application of a life cycle perspective and risk management in our continuous improvement processes; and encouragement of purchasing sustainable and energy-efficient products, technologies, and services.

Health and Safety Management

Health and safety incidents undergo monthly reviews at the local level and at the corporate level. The Board of Directors receives quarterly reports on recent events and the progress of the Health and Safety Strategy, alongside the quarterly financial results.

The Company has local EHS teams, hygiene and medical departments. In 2023, the Company strengthened its health and safety management organization by appointing a Chief Environment, Health and Safety (EHS) Officer. The responsibility for ensuring the occupational safety of all individuals within their assigned areas falls on the local managers of every production unit.

Workforce management

People’s management is structured at both local and corporate levels. The local Human Resources teams oversee general working conditions, such as working hours, leave policies, payroll processing, and union relations, which are closely tied to labor regulations. These matters are presented to Regional Presidents and Industrial Directors as necessary.

Compensation policies and procedures, including employee benefits and mobility schemes, are established at the corporate level. Annually, they undergo review in a dedicated meeting attended by the Global Compensation & HR Shared Service Senior Director and team, alongside the Chief Human Resources Officer and the CEO.

Furthermore, as part of the annual performance review process, career committees convene within each division to analyze performance and succession planning. This process is scaled up until a uniform curve and a general plan is developed for the entire company.

Topics related to work-life balance, diversity and inclusion, employee training, as well as talent attraction and retention, fall under the oversight of the Vice President of Global Talent Management. Subsequently, proposals are presented to the Chief Human Resources Officer and the CEO for approval.

Ternium's community programs are developed in collaboration with the Techint Group, aiming to create an international network of support and development across all affiliated companies. Within Ternium there are regional Community Relations teams responsible for implementing community programs in their respective regions and leading the relationship with the community stakeholders.

5.    SEGMENT INFORMATION
As of March 31, 2024, following the acquisition of an additional participation in Usiminas on July 3, 2023, the Chief Operating Decision Maker ("CODM") performed a review of the new business structure to decide on the allocation of resources and the assessment of performance, and decided to organize the Company in two operating segments: Steel and Mining.
The Steel segment includes the sales of steel products done by the Company's subsidiaries, which comprises mainly slabs, heavy plates, hot and cold rolled products, coated products, stamped steel parts for the automotive industry, roll-formed and tubular products, billets, bars and other products, including sales of energy.

The Mining segment includes the sales of mining products, done by the Company’s subsidiaries, mainly iron ore and pellets, and comprises the mining activities of Las Encinas, an iron ore mining company in which Ternium holds a 100% equity interest, the 50% of the operations and results performed by Peña Colorada, another iron ore mining company in which Ternium maintains that same percentage over its equity interest, and the mining activities of Mineraçao Usiminas, an iron ore mining company in which Usiminas holds a 70% equity interest.

Ternium's Chief Executive Officer ("CEO") functions as the CODM. The various geographic regions operate as an integrated steel producer. The CEO allocates resources and assesses performance of the Steel Segment as an integrated business and does the same with the Mining Segment. The CEO uses “Operating income – Management view” as per the below table as the key performance measure which differs from operating income determined in accordance with IFRS principally as follows:

•The use of direct cost methodology to calculate the inventories, while under IFRS is at full cost, including absorption of production overheads and depreciation.
•The use of costs based on previously internally defined cost estimates, while, under IFRS, costs are calculated at historical cost (with the FIFO method).
•In the case of Usiminas, the use of costs based in the weighted average cost, while, under IFRS, costs are calculated under the FIFO method.
•Other differences related to other operating income and expenses.

11.    INCOME TAX EXPENSE (continued)
Income tax expense for the years ended December 31, 2024, 2023 and 2022 differed from the amount computed by applying the statutory income tax rate in force in each country in which the company operates to pre-tax income as a result of the following:
Year ended December 31,
2024 2023 2022
Income before income tax 728,005  1,320,782  2,666,500 
Income tax expense at statutory tax rate (327,243) (643,686) (785,888)
Non taxable income —  39,755  — 
Non deductible expenses (5,793) —  (45,862)
Current tax expense related to Pillar II (21,436) —  — 
Effect of currency translation on tax base (1) (170,078) 180,582  241,426 
Recognition of previously unrecognized deferred tax assets 25,438  128,634  — 
Provision for tax losses (55,112) (53,122) — 
Recovery of income tax —  13,429  16,596 
Income tax expense (554,224) (334,408) (573,728)
(1) Ternium applies the liability method to recognize deferred income tax on temporary differences between the tax bases of assets and their carrying amounts in the financial statements. By application of this method, Ternium recognizes gains and losses on deferred income tax due to the effect of the change in the value on the tax basis in subsidiaries, which have a functional currency different to their local currency, mainly Mexico, Brazil and Argentina.
Tax rates used to perform the reconciliation between tax expense (income) and accounting profit are those in effect at each relevant date or period in each applicable jurisdiction.
In December 2021, the Organization for Economic Co-operation and Development (“OECD”) released the Pillar Two model rules (the Global Anti-Base Erosion rules, or “GloBE”) to reform international corporate taxation. Following Pillar Two OECD's initiative, the European Union adopted in December 2022 a directive to impose a global minimum taxation for multinational companies in the Union, to be effective as from 2024.
In May 2023, the IASB made narrow-scope amendments to IAS 12 setting an exception that provides relief from the requirement to recognize and disclose deferred taxes arising from enacted or substantively enacted tax laws that implement the Pillar Two model rules, including tax laws that implement qualified domestic minimum top-up taxes as per described in those rules.

On December 20, 2023, the Luxembourg Parliament approved the Pillar Two law transposing the EU Pillar Two Directive into domestic legislation. The law enters into force as from fiscal years starting on or after December 31, 2023.

The Company is within the scope of the rules, and therefore will be required to calculate its GloBE effective tax rate for each jurisdiction where it operates and will be liable to pay a top-up tax for the difference between its GloBE effective tax rate per jurisdiction and the 15% minimum rate, as from 2024.

The Company applies the exception to recognizing and disclosing information about deferred tax assets and liabilities related to Pillar Two income taxes, as provided in the amendments to IAS 12 issued in May 2023.

25.    CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS

Ternium is from time to time subject to various claims, lawsuits and other legal proceedings, including customer, employee, tax and environmental-related claims, in which third parties are seeking payment for alleged damages, reimbursement for losses, or indemnity. Management with the assistance of legal counsel periodically reviews the status of each significant matter and assesses potential financial exposure.
Some of these claims, lawsuits and other legal proceedings involve highly complex issues, and often these issues are subject to substantial uncertainties and, therefore, the probability of loss and an estimation of damages are difficult to ascertain. Accordingly, with respect to a large portion of such claims, lawsuits and other legal proceedings, Ternium is unable to make a reliable estimate of the expected financial effect that will result from ultimate resolution of the proceeding. In those cases, Ternium has not accrued a provision for the potential outcome of these cases.
If a potential loss from a claim, lawsuit or other proceeding is considered probable and the amount can be reasonably estimated, a provision is recorded. Accruals for loss contingencies reflect a reasonable estimate of the losses to be incurred based on information available to management as of the date of preparation of the financial statements and take into consideration litigation and settlement strategies. In a limited number of ongoing cases, Ternium was able to make a reliable estimate of the expected loss or range of probable loss and has accrued a provision for such loss but believes that publication of this information on a case-by-case basis would seriously prejudice Ternium’s position in the ongoing legal proceedings or in any related settlement discussions. Accordingly, in these cases, the Company has disclosed information with respect to the nature of the contingency but has not disclosed its estimate of the range of potential loss.
The Company believes that the aggregate provisions recorded for potential losses in its consolidated financial statements are adequate based upon currently available information. However, if management’s estimates prove incorrect, current reserves could be inadequate and Ternium could incur a charge to earnings which could have a material adverse effect on Ternium’s results of operations, financial condition, net worth and cash flows.

(i) Tax claims and other contingencies
The tax claims and other contingencies recognized at the increase of the participation of Usiminas are included in note 3.
(a) Provision for ongoing litigation related to the acquisition of a participation in Usiminas
The Company is party to a longstanding lawsuit filed in Brazil by Companhia Siderúrgica Nacional, or CSN, and various entities affiliated with CSN against Ternium Investments, its subsidiary Ternium Argentina, and Tenaris’s subsidiary Confab, all of which compose the T/T Group under the Usiminas shareholders agreement. The entities named in the CSN lawsuit had acquired participations in Usiminas in January 2012. The CSN lawsuit alleges that, under applicable Brazilian laws and rules, the acquirers were required to launch a tag-along tender offer to all non-controlling holders of Usiminas ordinary shares for a price per share equal to 80% of the price per share paid in such acquisition, or BRL28.8, and seeks an order to compel the acquirers to launch an offer at that price plus interest. If so ordered, the offer would need to be made to 182,609,851 ordinary shares of Usiminas not belonging to the Usiminas control group. Ternium Investments and Ternium Argentina’s respective shares in the offer would be 60.6% and 21.5%.

25.    CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS (continued)

On September 23, 2013, the first instance court dismissed the CSN lawsuit, and on February 8, 2017, the court of appeals maintained the understanding of the first instance court. CSN filed an appeal to the Superior Court of Justice (SCJ), seeking the review and reversal of the decision issued by the Court of Appeals, and on March 7, 2023, the SCJ, by majority vote, rejected CSN’s appeal.

CSN made several submissions in connection with the SCJ decision, including a motion for clarification that challenged the merits of the SCJ decision. Decisions at the SCJ are adopted by majority vote. At an October 17, 2023 session, two justices of the SCJ voted in favor of remanding the case to the first instance for it to be retried following production and assessment of the new evidence, and two justices of the SCJ voted, without requiring any further evidence, in favor of granting CSN’s motion for clarification and reversing the March 7, 2023 decision that rejected CSN’s appeal; because the fifth member of SCJ excused himself from voting, a justice from another panel at the SCJ was summoned to produce the tie-breaking vote. On June 18, 2024, the SCJ completed its voting on CSN’s motion for clarification and reversed, by majority vote, its March 7, 2023 decision, and resolved that Ternium Investments, its subsidiary Ternium Argentina and Tenaris’s subsidiary Confab should pay CSN an indemnification in connection with the acquisition by the T/T Group of the participations in Usiminas in January 2012, with CSN being allowed to retain ownership of the Usiminas ordinary shares it currently owns.

On August 1, 2024, Ternium Investments, Ternium Argentina and the other T/T Group entities filed a motion for clarification against the SCJ decision and, subsequently, CSN filed its reply. On December 6, 2024, the SCJ rejected this motion for clarification, confirming the obligation of the T/T Group entities to pay indemnification in connection with the 2012 acquisition of the participations in Usiminas. Notwithstanding the foregoing, the SCJ unanimously resolved to modify the applicable monetary adjustment mechanism and to cap the applicable attorney’s fees, thereby lowering the aggregate amount that would be payable if CSN ultimately prevails in this claim. Based on such SCJ decision, assuming monetary adjustment thorough December 31, 2024, and attorney’s fees in the amount of BRL5 million, the revised aggregate amount potentially payable by Ternium Investments and Ternium Argentina if CSN finally prevails on its claims would be of approximately BRL1,875.9 million (approximately $302.9 million at the BRL/$ rate as of such date) and BRL664.1 million (approximately $107.3 million at the BRL/$ rate as of such date), respectively.

The Company continues to believe that all of CSN's claims and allegations are unsupported and without merit, as confirmed by several opinions of Brazilian legal counsel, two decisions issued by the Brazilian securities regulator in February 2012 and December 2016, the first and second instance court decisions and the March 7, 2023 SCJ decision referred to above, and that in connection with the Usiminas acquisition the T/T Group was not required either to launch a tender offer or to pay indemnification to CSN. Accordingly, on February 10, 2025, Ternium filed an extraordinary appeal against the SCJ decisions that ordered an indemnification payment, seeking their review and reversal by the Supreme Federal Tribunal. The Company, however, cannot predict the ultimate resolution on the matter.

25.    CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS (continued)
(b) Potential Mexican income tax adjustment
In March 2015, as part of a tax audit with respect to fiscal year 2008, the Mexican tax authority ("SAT") challenged the deduction by Ternium Mexico of a tax loss arising from an intercompany sale of shares in December 2008. In addition, in September 2018, as part of a tax audit for fiscal year 2011, the SAT objected to the deduction by Ternium Mexico of the remainder of the 2008 tax loss. Ternium Mexico requested an injunction from the Mexican courts against the SAT claims and filed its defense and supporting documents with the SAT. After Ternium Mexico obtained an injunction in August 2020, in November 2020 the SAT issued a new preliminary audit report in which it reiterated its objections to the deduction of the 2008 tax loss. In June 2021, the SAT determined income tax adjustments with respect to 2008 and 2011 for amounts currently estimated at approximately $72.8 million and $35.6 million, respectively. Ternium Mexico appealed the SAT determinations.

More recently, however, Ternium Mexico withdrew its appeals and agreed to provide further information and documentation to the SAT. With all of the above-mentioned information and documentation, the SAT reduced the 2008 and 2011 tax adjustments downwards to approximately $17.5 million and $35.8 million, respectively. The Company had a tax provision of $53.3 million already included in its consolidated condensed interim financial statements as of September 30, 2023. The payment to the SAT was done on October 9, 2023, and the Company received formal documentation issued by the SAT with the closure of both audits.
(c) Tax assessments relating to the use of certain ICMS tax credits
The Imposto Sobre Operações Relativas à Circulação de Mercadorias e Serviços, or ICMS, is a Brazilian value-added tax on the services (inter-states) and the transfer of goods in Brazil. Payment of ICMS generates tax credits that, subject to applicable law, rules and regulations, may be either used to offset ICMS payment obligations generated in connection with domestic sales of products and services, or sold and transferred to third parties.
The Rio de Janeiro State Treasury Office is challenging the use by Ternium Brasil of ICMS tax credits generated in connection with purchases of refractory materials in the period from December 2010 through December 2016, and intends to assess taxes and impose fines on Ternium Brasil on the argument that such materials may not be qualified as “raw materials” or “intermediary products” but as “goods for consumption” and, accordingly, ICMS tax credits generated in connection with their purchase are not available and may not be used to offset ICMS payment obligations generated in connection with Ternium Brasil’s domestic sales of carbon steel slabs. Ternium Brasil has appealed against the Rio de Janeiro State Treasury Office tax assessments and fines. A provision in the amount of $57.7 million was recorded as of the acquisition date in connection with this matter ($29.3 million and $37.5 million as of December 31, 2024 and 2023, respectively).

(d) BP Energía México (BPEM) – Arbitration process

On February 2022, BP Energía México (“BPEM”) started an arbitration process against Gas Industrial de Monterrey, S.A. de C.V. (“GIMSA”), Ternium México and Ternium Gas México (“Respondents”), claiming payment for the gas supply from February 12 to February 28, 2021, for $27.6 million, $12.4 million, and $2.4 million, plus V.A.T. and interest, respectively. On June 9, 2024, after the arbitration process was completed, the arbitration award was notified and the Arbitration Tribunal ordered the Respondents to pay BPEM $22.0 million, $9.9 million and $2.1 million, plus V.A.T. and interest, respectively. Additionally, the Parties were ordered to pay expenses and costs for $2.4 million. As of September 30, 2024, the Company recognized a provision of $34.2 million in its consolidated condensed interim financial statements.

On October 25, 2024, the parties reached an agreement settling the reciprocal claims, and all parties formally dismissed the legal actions initiated with respect to the arbitration award.

(e) PIS and COFINS credits defense action - Usiminas

In August 2024, the Federal Government had filed two new tax claims for a total of approximately BRL 503 million ($92 million; BRL518 million or $84 million as of December 31, 2024). The contingencies are related to tax assessments that partially approved offset statements through which Usiminas claimed PIS and COFINS credits arising from a final court decision, which discussed the exclusion of ICMS from the calculation basis of said contributions. The tax authority disagreed with the calculation methodology adopted by Usiminas. Usiminas filed a defense action in the aforementioned proceedings, arguing that the calculations are correct and the credit rights should be recognized.

(ii) Commitments
The following are Ternium’s main off-balance sheet commitments:
(a) Ternium Argentina signed agreements, mainly with Vale S.A. and Mineração Corumbaense Reunida S.A., to cover 80% of its required iron ore, pellets and iron ore fines volumes until December 31, 2024, having no residual value as of such date. Although they do not set a minimum amount or a minimum commitment to purchase a fixed volume, under certain circumstances a penalty is established for the party that fails of:
- 7% in case the annual operated volume is between 70% and 75% of the total volume of purchases of the Company; such percentage is applied over the difference between the actual purchased volume and the 80% of the total volume of purchases.
- 15% in case the annual operated volume is lower than 70% of the total volume of purchases of the Company; such percentage is applied over the difference between the actual purchased volume and the 80% of the total volume of purchases.

(b) Ternium Argentina also signed various contracts for the provision and transportation of natural gas, including Tecpetrol and Energy Consulting Services S.A., both related companies of Ternium, assuming firm commitments for a total of $10.2 million payable until April 2025. Additionally, Ternium Argentina signed contracts for gas transportation with Transportadora de Gas del Norte S.A., a related company of Ternium, assuming firm commitments for a total of $28.5 million payable until April 2028.

(c) Ternium Argentina signed an agreement with Air Liquide Argentina S.A. for the supply of oxygen, nitrogen and argon, for an aggregate amount of $58.8 million, which is due to terminate in 2037.

(d) Ternium Argentina signed various contracts within its investment plan for the future acquisition of Property, plant and equipment for a total of $35.8 million. Also, Vientos de Olavarría, a subsidiary controlled by Ternium Argentina, subscribed various contracts for the maintenance and the operation of the wind farm for a total of $62.0 million payable until the year 2054.

(e) On April 24, 2017, Ternium Mexico entered into a 25-year contract (effective as of December 1, 2016, through December 1, 2041) with Techgen, S.A. de C.V. for the supply of 699 MW (which represents 78% of Techgen’s capacity) and covers most of Ternium Mexico’s facilities electricity needs. Monthly payments are determined on the basis of capacity charges, operation costs, back-up power charges, and transmission charges. As of the seventh contract year (as long as Techgen’s existing or replacing bank facility has been repaid in full), Ternium Mexico has the right to suspend or early terminate the contract if the rate payable under the agreement is higher than the rate charged by Comisión Federal de Electricidad (“CFE”) or its successors. Ternium Mexico may instruct Techgen to sell to any affiliate of Ternium Mexico, to CFE, or to any other third party all or any part of unused contracted energy under the agreement and Ternium Mexico will benefit from the proceeds of such sale. The contract with Techgen is under the Self Supply Scheme. According to this regulatory scheme, CFE needs to authorize the sale of energy to other third party final users. On August 27, 2021, Ternium México and Techgen signed an amendment to the contract to establish changes in the supply to Ternium; these changes were mainly connected to a new direct transmission line between Techgen and Ternium's Pesqueria Site for the direct supply of electricity to this site.
(f) Ternium México issued a guarantee letter covering up to approximately $28.8 million of the obligations of Gas Industrial de Monterrey, S.A. de C.V. (“GIMSA”), under the natural gas trading agreement between GIMSA and NEG Natural S.A. de C.V. (“NEG”). The credit line granted by NEG in connection with this natural gas trading agreement amounted to approximately $19.1 million. As of December 31, 2024, the outstanding amount under the natural gas trading agreement was $9.5 million, which is below the amount included in the guarantee letter issued by Ternium México.
(g) Ternium Mexico issued a guarantee letter covering up to approximately $58.7 million of the obligations of Techgen S.A. de C.V. ("Techgen") under the Clean Energy Certificates trading agreement between Techgen and Enel Green Power ("ENEL"). The amount equals the remnant balance if Techgen decides to terminate the agreement prior to the expiration date (and decreases as time of the contract passes). The contract was signed on May 25, 2018, and terminates on June 30, 2041.

On October 15, 2012, the agreement was authorized by the National Mining Agency (ANM). It has a duration of 30 years, or until the complete depletion of these mineral reserves. The monthly payments are linked to the volume of iron ore extracted from the areas covered by the agreement. Since 2015, a minimum annual volume of 3.6 million metric tons was established. If the annual volume of iron ore extracted is below the minimum volume, a payment under a take-or-pay arrangement will be due, calculated as the difference between the minimum volume and the volume effectively extracted. The outstanding amount was approximately $261.1 million as of December 31, 2024.

(y) In June 2016, Usiminas S.A. entered into electricity purchase agreement with Cemig S.A. for the Cubatão steel plant facilities until December 2030.

28.    RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
The following amendments, standards and interpretations have been applied on the year starting January 1, 2024:

Classification of Liabilities as Current or Non-current – Amendments to IAS 1 Non-current Liabilities with Covenants – Amendments to IAS 1

Amendments made to IAS 1 Presentation of Financial Statements in 2020 and 2022 clarified that liabilities are classified as either current or non-current, depending on the rights that exist at the end of the reporting period. Classification is unaffected by the entity’s expectations or events after the reporting date (e.g. the receipt of a waiver or a breach of covenant). The amendments require disclosures if an entity classifies a liability as non-current and that liability is subject to covenants that the entity must comply with within 12 months of the reporting date. The disclosures include the carrying amount of the liability, information about the covenants, and facts and circumstances, if any, that indicate that the entity may have difficulty complying with the covenants.

As of December 31, 2024, the Company's management had already assessed the effects of applying these amendments on the Company’s financial statements and had not identified any material impact in the application of these amendments.

Lease Liability in a Sale and Leaseback – Amendments to IFRS 16

In September 2022, the IASB finalized narrow-scope amendments to the requirements for sale and leaseback transactions in IFRS 16 Leases which explain how an entity accounts for a sale and leaseback after the date of the transaction.

As of December 31, 2024, the Company's management had already assessed the effects of applying these amendments on the Company’s financial statements and had not identified any material impact in the application of these amendments.

Deferred Tax related to Assets and Liabilities arising from a Single Transaction – Amendments to IAS 12

The amendments to IAS 12 Income Taxes require companies to recognize deferred tax on transactions that, on initial recognition, give rise to equal amounts of taxable and deductible temporary differences, and will require the recognition of additional deferred tax assets and liabilities. The amendment should be applied to transactions that occur on or after the beginning of the earliest comparative period presented. In addition, entities should recognize deferred tax assets (to the extent that it is probable that they can be utilized) and deferred tax liabilities at the beginning of the earliest comparative period for all deductible and taxable temporary differences associated with right-of-use assets and lease liabilities, and decommissioning, restoration and similar liabilities, and the corresponding amounts recognized as part of the cost of the related assets.

As of December 31, 2023, the Company's management had already assessed the effects of applying these amendments on the Company’s financial statements and had not identified any material impact in the application of these amendments.

28.    RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS (continued)

OECD Pillar Two Rules – Amendments to IAS 12

In December 2021, the Organization for Economic Co-operation and Development (“OECD”) released the Pillar Two model rules (the Global Anti-Base Erosion rules, or “GloBE”) to reform international corporate taxation. Following Pillar Two OECD’s initiative, the European Union adopted in December 2022 a directive to impose a global minimum taxation for multinational companies in the Union, to be effective as from 2024. In May 2023, the IASB made narrow-scope amendments to IAS 12 setting an exception that provides relief from the requirement to recognize and disclose deferred taxes arising from enacted or substantively enacted tax laws that implement the Pillar Two model rules, including tax laws that implement qualified domestic minimum top-up taxes as per described in those rules.

No current tax impacts were recognized in the Consolidated Financial Statements as of December 31, 2023, due to the application of Pillar Two rules, as they were applicable as from 2024 in jurisdictions relevant for the Company. As of December 31, 2024, the Company recognized the corresponding charges in current tax (see note 11). In addition, the Company has applied the exception prescribed by the amendments to IAS 12, and therefore it has not recognized any deferred tax impact from the Pillar Two application.

The following standards, amendments to standards and interpretations are not mandatory for the financial year beginning January 1, 2024, and have not been early adopted:

IFRS 18, ‘Presentation and disclosure in Financial Statements’

In April 2024, the IASB issued IFRS 18, “Presentation and disclosure in financial statements”, which introduces new requirements to present specified categories and defined subtotals in the statement of profit or loss, provide disclosures on management-defined performance measures (MPMs) in the notes to the financial statements and improve aggregation and disaggregation. Once implemented, it will replace IAS 1, carrying forward many of the requirements in IAS 1 unchanged and complementing them. IFRS 18 must be applied on annual periods beginning on or after January 1, 2027. The Company's management is currently assessing the potential impact that the application of this standard may have on the Company's financial condition or results of operations.

Other standards and interpretations non-significant for the Company’s financial statements:
–Amendments to IAS 7 and IFRS 7 - Supplier finance arrangements
–IFRS 19 Subsidiaries without Public Accountability: Disclosures Ternium’s activities expose the Company to a variety of risks: market risk (including the effects of changes in foreign currency exchange rates, interest rates and commodities prices), credit risk and liquidity risk.

29. FINANCIAL RISK MANAGEMENT
1) Financial risk factors
Ternium’s overall risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse effects on the financial performance. Ternium’s subsidiaries may use derivative financial instruments to hedge certain risk exposures.
1.1) Market Risk
(i) Foreign exchange rate risk
Ternium operates and sells its products in different countries, and as a result is exposed to foreign exchange rate volatility. Ternium’s subsidiaries may use derivative contracts in order to hedge their exposure to exchange rate risk derived from their trade and financial operations.
Ternium’s foreign exchange policy seeks to minimize the impact of fluctuations in the value of other currencies with respect to the U.S. dollar. Ternium’s subsidiaries monitor their actual and expected short-term net cash flows in currencies other than the U.S. dollar and analyze potential hedging according to its needs in line with its derivative policy. This hedging can be carried out either by netting positions or by financial derivatives. However, regulatory or legal restrictions in the countries in which Ternium’s subsidiaries operate, could limit the possibility of the Company carrying out its hedging policy.
The following table shows a breakdown of Ternium’s assessed financial position exposure to currency risk as of December 31, 2024:
Exposure to
functional currency
$ million BRL million
US dollar ($) —  (187)
EU euro (EUR) 33  (5)
Argentine peso (ARS) 18  — 
Mexican peso (MXN) (801) — 
Brazilian real (BRL) (297) — 
Colombian peso (COP) (64) — 
Yen (JPY) 99  — 
Other currencies (1) (0)
    
The main relevant exposures correspond to:
(a)Argentine peso vs. U.S. dollar
If the Argentine peso had weakened by 1% against the U.S. dollar, it would have generated a pre-tax loss of $0.2 million and a pre-tax gain of $1.3 million as of December 31, 2024 and 2023, respectively.
(b)Mexican peso vs. U.S. dollar
If the Mexican peso had weakened by 1% against the U.S. dollar, it would have generated a pre-tax gain of $8.0 million and $3.1 million as of December 31, 2024 and 2023, respectively.

29.    FINANCIAL RISK MANAGEMENT (continued)

(c)Colombian peso vs. U.S. dollar
If the Colombian peso had weakened by 1% against the U.S. dollar, it would have generated a pre-tax gain of $0.6 million and $0.2 million as of December 31, 2024 and 2023, respectively.

(d)    Brazilian real vs. U.S. dollar
If the Brazilian real had weakened by 1% against the U.S. dollar, it would have generated a pre-tax loss of $3.0 million and $5.3 million as of December 31, 2024 and 2023, respectively.

We estimate that if the Argentine peso, Mexican peso, Colombian peso and Brazilian real had weakened simultaneously by 1% against the U.S. dollar with all other variables held constant, total pre-tax gain for the year would have been $5.4 million higher (total pre-tax loss of $0.6 million higher as of December 31, 2023), as a result of foreign exchange gains/losses on translation of U.S. dollar-denominated financial position, mainly local currency cash, trade receivables, trade payables, tax credits and liabilities, lease liabilities, borrowings and other liabilities.
Considering the same variation of the currencies against the U.S. dollar of all net investments in foreign operations amounting to $2.3 billion, the currency translation adjustment included in total equity would have been $5.2 million higher, arising mainly from the adjustment on translation of the equity related to the Brazilian real during the year 2024.
(ii) Interest rate risk
Ternium manages its exposure to interest rate volatility through its financing alternatives and hedging instruments. Borrowings issued at variable rates expose the Company to the risk of increased interest expense in the event of a raise in market interest rates, while borrowings issued at fixed rates expose the Company to a variation in its fair value. The Company’s interest-rate risk mainly arises from long-term borrowings that bear variable-rate interest that could be partially fixed through different derivative transactions, such as interest rate swaps.
Ternium’s nominal weighted average interest rate for its debt instruments, which do not include neither the effect of derivative financial instruments, nor the devaluation of the local currencies, was 8.83% and 8.46% as of December 31, 2024 and 2023, respectively. These rates were calculated using the rates set for each instrument in its corresponding currency and weighted using the dollar-equivalent outstanding principal amount of each instrument.
Ternium’s total variable interest rate debt amounted to $1,140.1 million (51.1% of total borrowings) as of December 31, 2024, and $1,065.9 million (49.7% of total borrowings) as of December 31, 2023.
If interest rates on the aggregate average notional of U.S. dollar denominated borrowings held during 2024, excluding borrowings with derivatives contracts mentioned in Note 22 (a), had been 100 basis points higher with all other variables held constant, total pre-tax income for the year ended December 31, 2024 would have been $21.1 million lower ($18.3 million lower as of December 31, 2023).

29.    FINANCIAL RISK MANAGEMENT (continued)
1.2) Credit risk
Credit risk arises from cash and cash equivalents, deposits with banks and financial institutions, as well as credit exposures to customers, including outstanding receivables and committed transactions. Ternium’s subsidiaries have credit guidelines in place to ensure that derivative and treasury counterparties are limited to high credit quality financial institutions.
Ternium invests in financial assets with a minimum credit rating of investment grade established by an international qualification agency renowned in the financial market, in line with corporate investment portfolio policies. Approximately 41.0% of the Company’s liquid financial assets correspond to investment grade rated instruments as of December 31, 2024, in comparison with approximately 34.8% as of December 31, 2023.

Ternium has no significant concentrations of credit risk from customers. No single customer accounts for more than ten percent of Ternium’s sales. Ternium’s subsidiaries have policies in place to ensure that sales are made to customers with an appropriate credit history, and that credit insurances, letters of credit or other instruments are requested to reduce credit risk whenever deemed necessary. The subsidiaries maintain allowances for potential credit losses. The utilization of credit limits is regularly monitored.
Trade and other receivables are carried at face value less allowance for doubtful accounts, if applicable. This amount does not differ significantly from fair value. The other receivables do not contain significant impaired assets.
As of December 31, 2024, trade receivables total $1,562.1 million ($2,065.5 million as of December 31, 2023). These trade receivables are collateralized by guarantees under letter of credit and other bank guarantees of $1.0 million ($1.4 million as of December 31, 2023), credit insurance of $576.5 million ($686.2 million as of December 31, 2023) and other guarantees of $27.0 million ($9.4 million as of December 31, 2023).
As of December 31, 2024, trade receivables of $1,515.1 million ($1,910.9 million as of December 31, 2023) were fully performing.
As of December 31, 2024, trade receivables of $99.4 million ($214.1 million as of December 31, 2023) were past due (mainly up to 180 days).

29.    FINANCIAL RISK MANAGEMENT (continued)
Fair Value by Hierarchy
Following the requirements contained in IFRS 13, Ternium categorizes each class of financial instrument measured at fair value in the statement of financial position into three levels, depending on the significance of the judgment associated with the inputs used in making the fair value measurements:
–Level 1 comprises financial assets and financial liabilities whose fair values have been determined on the basis of quoted prices (unadjusted) in active markets for identical assets or liabilities.
–Level 2 includes financial assets and financial liabilities for which fair values have been estimated using inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices).
–Level 3 comprises financial instruments for which inputs to estimate fair value of the assets or liabilities are not based on observable market data (unobservable inputs).
The following table presents the assets and liabilities that are measured at fair value as of December 31, 2024 and 2023:
Fair value measurement as of December 31, 2024

29.    FINANCIAL RISK MANAGEMENT (continued)
There were no significant transfers between Level 1 and Level 2 of the fair value hierarchy, there were no transfers from Level 1 to Level 3, and there were transfers of Non-U.S. Government securities from Level 3 to Level 2.
The fair value of financial instruments traded in active markets is based on quoted market prices at the reporting date. A market is regarded as active if quoted prices are readily and regularly available from an exchange, dealer, broker, industry group, pricing service, or regulatory agency, and those prices represent actual and regularly occurring market transactions on an arm’s length basis. The quoted market price used for financial assets held by Ternium is the current mid-price. These instruments are included in Level 1 and comprise primarily corporate and sovereign debt securities.
The fair value of financial instruments that are not traded in an active market (such as certain debt securities, certificates of deposits with original maturity of more than three months, forward and interest rate derivative instruments) is determined by using valuation techniques which maximize the use of observable market data when available and rely as little as possible on entity specific estimates. If all significant inputs required to value an instrument are observable, the instrument is included in Level 2. Ternium values its assets and liabilities included in this level using mid prices, interest rate curves, broker quotations, current exchange rates and forward rates volatilities obtained from market contributors as of the valuation date.
If one or more of the significant inputs are not based on observable market data, the instruments are included in Level 3. Ternium values its assets and liabilities in this level using observable market inputs, information provided by fund managers and management assumptions which reflect the Company’s best estimate on how market participants would price the asset or liability at measurement date.
3)    Accounting for derivative financial instruments and hedging activities
Depending on the nature of the hedged item, Ternium either recognizes its derivative financial instruments’ transactions in the statement of financial position at cost and subsequently measures changes on a monthly basis at fair value, or undertakes hedge accounting, classifying these transactions as cash flow hedges. While changes in fair value are disclosed under “Other financial income (expenses), net” line item in the income statement, changes in transactions classified as cash flow hedges are disclosed as an equity reserve in the statement of comprehensive income. Ternium does not hedge its net investments in foreign entities.
Ternium designates certain derivatives as hedges of a particular risk associated with a recognized asset or liability or a highly probable forecast transaction. These transactions are classified as cash flow hedges (mainly capital expenditures). The effective portion of the fair value of derivatives that are designated and qualify as cash flow hedges is recognized within other comprehensive income. Amounts accumulated in other comprehensive income are recognized in the income statement in the same period than any offsetting losses and gains on the hedged item. Once the hedged item gets settled, the gain or loss relating to the ineffective portion is recognized immediately in the income statement. The fair value of Ternium derivative financial instruments (asset or liability) continues to be reflected on the statement of financial position

TERNIUM S.A.
Consolidated Financial Statements as of December 31, 2024 and 2023
and for the years ended December 31, 2024, 2023 and 2022





29.    FINANCIAL RISK MANAGEMENT (continued)
For transactions designated and qualifying for hedge accounting, Ternium documents the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedge transactions. The Company also documents its assessment, on an ongoing basis, of whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items. As of December 31, 2024 and 2023, the effective portion of designated cash flow hedges (net of taxes) amounted to $(37.3) million and $15.9 million, respectively, and were included under "changes in the fair value of derivatives classified as cash flow hedges" line item in the statement of comprehensive income (see Note 27 (a)).

The fair values of various derivative instruments used for hedging purposes are disclosed in Note 22. The full fair value of a hedging derivative is classified as a non-current asset or liability when the remaining maturity of the hedged item is more than 12 months and as a current asset or liability when the remaining maturity of the hedged item is less than 12 months.

Changes in the fair value of any derivative instruments that do not qualify for hedge accounting under IAS 39 are recognized immediately in the income statement.

4)    Fair value estimation

The estimated fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale.

For the purpose of estimating the fair value of financial assets and liabilities with maturities of less than one year, the Company uses the market value less any estimated credit adjustments. For other investments, the Company uses quoted market prices.

As most borrowings incorporate floating rates that approximate market rates and the contractual repricing occurs mostly every one month, the fair value of the borrowings approximates their carrying amount and it is not disclosed separately.

In assessing the fair value of derivatives and other financial instruments, Ternium uses a variety of methods, including, but not limited to, estimated discounted value of future cash flows using assumptions based on market conditions existing at each year-end.

30.    FOREIGN EXCHANGE RESTRICTIONS IN ARGENTINA

Ternium’s Argentine subsidiary, Ternium Argentina S.A., is currently operating in a complex and volatile economic environment.

Between September 2019 and December 13, 2023, the Argentine government imposed significant restrictions on foreign exchange transactions. Although after a new administration took office in Argentina in December 2023 certain restrictions were eased and other changes to such regulations are expected, at the date of these Consolidated Financial Statements the application of existing foreign exchange regulations remains uncertain and the scope and timing of upcoming changes remain unknown. The main currently applicable measures are described below:

• Access to the Argentine foreign exchange market (“MULC”) to pay for imports of services rendered by related and non-related parties (including royalties) on or before December 12, 2023, is subject to Argentine Central Bank approval. Currently, these approvals are rarely, if ever, granted. Access to the MULC to pay for imports of services that were rendered or accrued as from December 13, 2023, does not require government approval, but payment is deferred 30 calendar days as from the date of supply or accrual of the service (if the service was rendered by a non-related party) or 180 calendar days (if rendered by a related party).

• In the context of high, but decelerating, inflation during 2024, restrictions of access to the MULC to pay for imports of goods remain, but have been gradually made more flexible. The price for imports with customs clearance on or after October 21, 2024, may be paid in full as from on the 30th day from the date of customs clearance. In addition, the price for imports with customs clearance between August 1 and October 20, 2024, may be paid in two equal installments on the 30th and 60th day from the date of customs clearance, and the price for imports with customs clearance between December 13, 2023, and July 31, 2024, may be paid in four equal installments payable on the 30th, 60th, 90th and 120th day from the date of customs clearance. Access to the MULC to pay for imports that obtained customs clearance on or before December 12, 2023, continues to require Argentine Central Bank approval.

• Foreign currency proceeds derived from exports of goods must be sold into the MULC and converted into Argentine pesos within 60 days (if made to related parties) or 180 days (if made to unrelated parties) from shipment date, or, if collected earlier, within five days of collection. Foreign currency proceeds from exports of services must be sold into the MULC and converted into Argentine pesos within five business days of collection. As from December 13, 2023, up to 20% of export of goods or services proceeds can be sold for Argentine pesos through securities transactions resulting in a higher implicit exchange rate, as described further below. This percentage has changed over time.

• Access to the MULC to make dividend payments requires prior Argentine Central Bank approval. When required, Argentine Central Bank approvals are rarely, if ever, granted.

Ternium Argentina carries out all of its import and export transactions through the MULC. Therefore, assets and liabilities in foreign currency as of December 31, 2024, have been valued considering the official exchange rates at the end of the period.

30.    FOREIGN EXCHANGE RESTRICTIONS IN ARGENTINA (continued)

Under Ternium Argentina’s annual accounts as of December 31, 2024, and for the year then ended, revenues amounted to $2,212 million (2023: $3,419 million), net profit from continuing operations to $149 million (2023: $686 million), total assets to $5,726 million (2023: $5,083 million), total liabilities to $790 million (2023: $759 million) and shareholders’ equity to $4,936 million (2023: $4,324 million).

Ternium Argentina’s cash and cash equivalents and other investments amounted to $1,293 million as of December 31, 2024,
broken down as follows:
- $1,275 million in U.S. dollars-denominated instruments in sovereign bonds issued by the Argentine Government and payable in U.S. dollars, and Argentine Treasury bonds related to the official exchange rate. The U.S. dollar value of these instruments recorded in Ternium’s consolidated financial statements is based on their Argentine peso local market price, converted to the U.S. dollar at the ARS/$ official exchange rate. Therefore, the valuation of such investments is subject to the volatility of the Argentine financial market and currency exchange rates, leading to a potential significant reduction of such value in the consolidated financial statements.
- $17 million in Argentine pesos-denominated instruments.
- $1 million in negotiable obligations and promissory notes issued by Argentine export driven companies in U.S. dollars and mainly payable in Argentine pesos.

Ternium Argentina’s financial position in ARS as of December 31, 2024, amounted to $218 million in monetary assets and $184 million in monetary liabilities. All of Ternium Argentina’s ARS-denominated assets and liabilities are valued at the prevailing official exchange rate. In the event of a devaluation, Ternium Argentina may be adversely affected, and will also suffer a loss on deferred tax charge as a result of a deterioration on the tax value of their fixed assets. At this time, the Company is unable to estimate all impacts of a new devaluation of the Argentine peso against the U.S. dollar.

On April 24, 2023, Ternium Argentina’s board of directors approved the payment of a dividend in kind in US dollar-denominated Argentine bonds for a total amount of up to $624 million. On May 4, 2023, Ternium received its share of the dividend in kind. Considering the impact of foreign exchange restrictions in Argentina and based on the value of the bonds in the international market, Ternium recorded in its equity a negative reserve as of the collection date. With the disposal of a portion of these instruments, the Company partially reclassified such reserve to financial results. As of December 31, 2024, the equity reserve was fully reclassified to financial results upon disposal of these remaining bonds.

This context of volatility and uncertainty remains in place as of the issue date of these Consolidated Financial Statements. Management continues to monitor closely the evolution of the main variables affecting its business, identifying the potential impact thereof on its financial and economic situation and determining the appropriate course of action in each case. The Company’s Consolidated Financial Statements should be read taking into account these circumstances.

31. SUBSEQUENT EVENTS

a. Annual Dividend Proposal

Upon approval of the Company´s 2024 annual accounts, the Board of Directors intends to propose, for the approval of the Annual General Shareholders' meeting to be held on May 6, 2025, the payment of an annual dividend of $0.27 per share ($2.70 per ADS), or approximately $530 million, which includes the interim dividend of $0.09 per outstanding share ($0.90 per ADS) or approximately $177 million, paid on November 21, 2024. If the annual dividend is approved by the shareholders, a dividend of $0.18 per share ($1.80 per ADS), or approximately $353 million will be paid on May 14, 2025, with an ex-dividend date of May 9, 2025. These Consolidated Financial Statements do not reflect this dividend payable.

b. Recently Announced Tariffs on Imports in the United States

On February 1, 2025, the U.S. government announced the imposition, through the International Emergency Economic Powers Act (IEEPA), of tariffs applicable to all products imported from Mexico, Canada and China. As of the date of these financial statements, Mexican and Canadian products that comply with USMCA preferential rules of origin, are exempt from this tariff. Further, the Trump administration announced that the U.S. would implement reciprocal tariffs with trading partners by April 2025.

In addition, on March 12, 2025, the U.S. government imposed a 25% tariff on virtually all imports of steel and on certain steel derivatives, revoking previously negotiated country-specific exemptions and quota arrangements.

Moreover, on March 26, 2025, the U.S. government announced a 25% tariff under Section 232 on all imported automobiles produced outside the U.S., effective from April 3, 2025. This tariff will also apply to key auto parts such as engines, transmissions, powertrain parts and electrical components starting on May 3, 2025. However, vehicles and parts that comply with the USMCA will only be subject to this tariff on their non-U.S. specific content, and, in the case of auto parts, only when the government establishes a process to exempt U.S. content from tariffs.

Other countries have announced retaliatory tariffs against U.S. exports. It is also anticipated that parties may bring litigation regarding the timeliness and appropriateness of the Trump administration’s actions. In light of the foregoing uncertainties, Ternium is unable at this time to predict the evolution or ultimate outcome of these developments or to quantify the impact that the new tariffs and measures would have on its business or financial condition.

Alternative performance measures

Free cash flow
Free cash flow (FCF) is a measure of financial performance, calculated as operating cash flow less capital expenditures. FCF represents the cash that a company is able to generate after spending the money required to maintain or expand its asset base. FCF is calculated in the following manner:

Free cash flow = net cash provided by operating activities – capital expenditures.
For the year ended December 31,
U.S. dollar million 2024 2023 2022
Net cash provided by operating activities 1,906 2,501 2,753
Less: capital expenditures (1,865) (1,461) (581)
Free cash flow 41 1,040 2,172


Net cash
This is the net balance of cash and cash equivalents and other investments (current and non-current), adjusted to exclude other investments in SGR (non-current), less borrowings. It provides a summary of the financial solvency and liquidity of the company. Net cash is widely used by investors and rating agencies and creditors to assess the company’s leverage, financial strength, flexibility and risks. Net cash is calculated in the following manner:

Net cash = cash and cash equivalents + other investments (current and non-current) – borrowings (current and non-current).

For the year ended December 31,
U.S. dollar billion 2024 2023 2022
Cash and cash equivalents 1.7 1.8 1.7
Plus: other investments (current and non-current) 2.2 2.2 2.0
Less: borrowings (current and non-current) (2.2) (2.1) (1.0)
Net cash 1.6 1.9 2.6

Note:    Ternium Argentina's consolidated position of cash and cash equivalents and other investments amounted to $1.3, $1.1 and $1.3 billion as of December 31, 2024, 2023 and 2022, respectively.
