Sylvamo Corporation (the “Company” or “Sylvamo”, which may also be referred to as “we” or “us”) is a global uncoated papers company with a broad portfolio of top-tier brands and low-cost, large-scale paper mills located in and serving the most attractive geographies, including Europe, Latin America and North America, which are our business segments. We produce uncoated freesheet (“UFS”) for paper products such as cutsize and offset paper, as well as market pulp. With roots going back to 1898, we have a long history of offering premium quality papers to meet the needs of our customers and end-users. Our mills predominantly rank in the lowest quartile on global and regional UFS cost curves, and we believe our low-cost operations enable us to serve our customers with the highest quality products at attractive margins. Our industry-leading brands, known for their long-standing reputation in their respective markets for product quality and performance, allow us to maintain our long-term relationships with top-tier customers throughout economic cycles. Our international reach and strong positioning across retail, merchant and e-commerce channels optimally positions us to meet the paper needs of our end-users around the world. This also provides geographical diversification of our revenue and profits. From 2022 to 2024, on average, we generated 46% of our revenues and 41% of our Business Segment Operating Profit in Europe and Latin America. Each region in which we operate exhibits different supply and demand characteristics. Both Latin America and North America have strong profitability for the uncoated paper industry relative to other geographies. See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Business Segment Results - Results of Operations for a definition of Business Segment Operating Profit.

During the second quarter of 2022, we committed to a plan to sell our Russian operations (which were sold on October 2, 2022). Our operations in Russia included a paper mill in Svetogorsk, Russia and long-term harvesting rights on 860,000 acres of government-owned forestland. As this divestiture was a strategic shift away from the Russian markets, we have presented the historical operating results of the Russian operations as “discontinued operations” as applicable (see Note 8 Divestiture and Impairment of Business to the Consolidated Financial Statements included in Item 8 in this Annual Report on 10-K for additional discontinued operations information). As a result, the narrative discussion in this Item 1 relates only to our continuing operations, and all other financial results, disclosures and discussions of the Company’s continuing operations appearing elsewhere in this Annual Report on Form 10-K exclude our Russian operations, unless otherwise noted.

In January 2023, the Company completed the previously announced acquisition of Stora Enso’s uncoated freesheet paper mill in Nymölla, Sweden, for €157 million (approximately $167 million), subject to customary purchase price adjustments. The integrated mill has the capacity to produce approximately 500,000 short tons of uncoated freesheet on two paper machines. The Nymölla mill’s results of operations are included in Sylvamo’s consolidated financial statements from the date of acquisition. See Note 7 Acquisitions to the Consolidated Financial Statements included in Item 8 in this Annual Report on 10-K for further details.

The markets in which we operate are highly competitive with well-established domestic and foreign manufacturers. For instance, in North America, the four largest manufacturers of UFS, including Sylvamo, represent approximately 80% of the total annual production capacity. As the use of electronic mediums and alternative products increases, and because paper production does not generally rely on proprietary processes, except for highly specialized papers or products, the areas into which Sylvamo sells its principal products are increasingly competitive. Furthermore, the level of competitive pressure Sylvamo may face is dependent, in part, upon exchange rates, particularly the rate between the U.S. dollar and the Euro and the U.S. dollar and the Brazilian real. Some of our competitors have shut down or converted mills or paper machines at their mills to linerboard, pulp and boxboard capacity, which reduced the supply of UFS and other printing papers.

Sylvamo sells products directly to end users and converters, as well as through agents, resellers and paper distributors.

The Company’s principal products are described in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Raw materials essential to our businesses include wood fiber, chemicals, water and energy. Information about our sources and the availability to us of raw materials, particularly wood, the principal raw material from which our products are made, is included in Item 1A. Risk Factors - “Changes in the cost or availability of raw materials and energy used to manufacture our products could have a material adverse effect on our business, financial condition and results of operations” and Item 7. Managements’s Discussion and Analysis of Financial Condition and Results of Operations.

Sylvamo’s capabilities and potential are delivered through our dedicated, talented and diverse workforce, which we believe is among the best in the industry. We employ over 6,500 people globally, with 25%, 49% and 26% of our workforce located primarily in 13 countries in Europe, Latin America and North America, respectively. A portion of our workforce is represented by unions in Brazil, France, Sweden and, in the United States, at our mill in Ticonderoga, New York. We believe that our relationships with our unions are constructive.

We strive to be the employer of choice. We aim to attract, retain and develop talented and diverse employees that reflect our diverse communities and global end-users of our paper. To that end, we work to foster a safe and inclusive workplace where all employees feel safe, welcomed, valued, engaged, fairly compensated and have opportunities for professional development.

Our priority is people before paper -- the health and safety of our employees, contractors and visitors to our facilities are paramount. We strive to design and operate injury-free workplaces for our employees and everyone who enters our facilities. As responsible stewards of people and their communities, we have emphasized safety at our Company and strictly complied with national regulations such as, in the United States, the Occupational Safety and Health Administration’s regulations. Based on our safety record and our comparison of it against publicly available industry safety information, we are an industry-leading company in employee safety.

We track our safety record. Information about our safety record is available on our website, sylvamo.com, and in our annual sustainability performance review. Our Sustainability Performance Review for 2023 is available on our website, sylvamo.com. We will post our Sustainability Performance Review for 2024 on our website when it is completed, which is expected in the first half of 2025.

We take precautions to protect the health and safety of our employees and comply with applicable government requirements and safety guidance in the three regions where we operate. We continue to promote safety through our “People Before Paper” program, which we first introduced in 2022. This program promotes increasing safety, especially in the manufacturing setting, by emphasizing focus on one safe task a time and stopping work if work conditions appear unsafe. It further emphasizes mental health and overall well-being as important to increasing safety. Since we introduced the program, we have consistently worked to increase safety through initiatives developed and implemented under the program. These initiatives included ongoing communications and training, as well as our leadership’s insistence that employees put people’s safety before operations, always.

As we have promoted safety and tracked our safety performance, we have found it challenging to ensure that injuries are avoided. Therefore, in 2024, we ramped up efforts under our safety program, including: adding even more frequent communications from our leadership emphasizing safety; implementing further safety training at our facilities with a focus on specific areas for safety improvements; conducting an organization-wide safety “stand-down,” ceasing work, to emphasize that we want employees to speak up and stop work if conditions seem unsafe; providing recognition to employees who have improved safety, such as by seeing and bringing attention to a potentially unsafe issue or proposing safety improvements; and having employees who have contributed to safety improvements share how they improved safety, at periodic company-wide safety meetings. Additionally, we frequently communicate and emphasize to employees the importance of, and have provided opportunities for them to enhance, their physical and mental health and well-being. We have Employee Assistance Programs and additional benefit resources available in all regions where we operate to support our employees’ health and well-being.

Notwithstanding our efforts to ensure a safe workplace and support the physical and mental health of our employees, we cannot guarantee that our efforts will always be successful. Success is subject to risks and uncertainties, both known and unknown, including risks noted in Item 1A. Risk Factors, including A public health crisis could have a material adverse effect on our business, financial condition, results of operations and cash flows and elsewhere in this Annual Report on Form 10-K. A failure to keep our employees and others safe on our premises could disrupt our operations, result in losses associated with liability or potential liability to the harmed individual and to applicable governmental agencies responsible for regulation of safety, and cause us reputational harm.

Our talent strategy focuses on attracting and retaining the best employee talent from the diverse backgrounds of the communities where we operate. We aim to foster for employees a work culture where employees from those diverse backgrounds work well together, are treated fairly, and are valued for their talents and the viewpoints that they bring to the table. We aim to provide competitive compensation and benefits, reward individual, team and company performance, provide professional development opportunities, promote employee health and well-being, and encourage engagement by showing our employees that we value their commitment to our company objectives, to each other and to their communities.

To provide our employees globally competitive and fair compensation and benefits, we periodically review, adjust and align our compensation practices with best practices around the material elements of our compensation structure.

Our employee recruiting includes developing and recruiting new talent through lateral and college recruiting efforts. As an example of such college recruiting efforts, in the United States, Brazil and Europe, we have programs that include internships and trainee programs to attract college hires, with a special focus on preparing early career engineers and safety professionals to be future leaders at Sylvamo. We believe that these efforts help develop a strong, talented and diverse workforce at Sylvamo.

We support, encourage and provide our employees with opportunities to strengthen their connection and commitment to Sylvamo and the communities where they work and live, because a highly engaged workforce is important to our business success. In 2024, we launched a global engagement survey. Through the survey, we determined that engagement levels at Sylvamo in all regions where we have employees are fairly high, and we established a baseline for engagement levels to consistently work to improve upon. Also in 2024, we provided multiple opportunities, in the various regions where we operate, for our employees to engage in and help their communities. We share information about some of these engagement opportunities at the “Why we Care” tab on our website, sylvamo.com.

We develop the capabilities of our employees through our continuous learning, development and performance management programs. We invest in their growth and development by providing a multi-dimensional approach to learning. This approach includes various learning journeys to help employees grow personally and professionally and advance within our organization, including for specific positions, for specific development targets, and for development of competencies and Sylvamo’s culture. These learning resources are intended to provide employees with the skills they need to achieve their career goals, build management skills and be leaders at Sylvamo.

A component of our overall effort to attract and retain exceptional employee talent, supporting our objective to be the employer of choice, is to cultivate a workforce where employees from diverse backgrounds are represented, engaged and empowered to inspire innovative ideas and decisions, where employees feel welcome, included and valued, and where all employees are treated fairly, regardless of background.

Our senior management team is internationally diverse with global experience, hailing from all of the geographies in which we operate — Europe, Latin America and North America. We have a Global I&D Council that develops our I&D strategy and helps identify and implement means for our strategy to succeed. The Global I&D Council meets quarterly and includes a range of employees at various levels of leadership, who are from the regions where we operate and are of diverse races, genders and cultural backgrounds. In 2024, the efforts of the Global I&D Council resulted in initiatives that included training managers on strengthening the ability of our leaders to facilitate inclusive work teams, providing employee mentoring and networking opportunities, and facilitating means for employees to identify and leverage opportunities for their career growth and advancement. Our employee inclusion networks, which we started in 2022, continued to meet in 2024. All initiatives and employee inclusion networks are voluntary and open to all employees.

Management keeps our senior leadership and board of directors aware of our I&D initiatives and progress through periodic reports. The Management Development and Compensation Committee of our board of directors is responsible for oversight of I&D matters.

Our hiring and retention efforts are challenged by competition for labor having a high level of the various skills needed in our industry, particularly at our mills, which makes our cost of labor high compared to industries that require less skilled labor. We have not experienced any material shortage of labor, but if the labor supply were to contract substantially in any of the regions where we operate, it could impede our ability to attract and retain employee talent and further increase our cost of labor. For more information regarding our risks relating to the labor market, see Item 1A. Risk Factors, particularly – “Our business and business prospects could be materially adversely affected if we fail to attract and retain senior management and other key employees.”

Our hiring and retention efforts focus on ensuring equal opportunities in hiring and promotion, enhanced by our inclusion and diversity efforts that value employees of all backgrounds and talents and that, without regard to their backgrounds, provide employees with access to the support we provide for career growth and success. There is risk, particularly in the United States, that such efforts could expose us to legal challenges relating to such efforts. There is also risk that, despite our efforts, we will not achieve our aspirational goals or adequately foster the work culture described above.

In 2023 and 2024, we conducted “Project Horizon” to streamline our organization and reduce costs, based upon an evaluation of our needs at all levels of the organization. We eliminated a number of salaried positions and reorganized job responsibilities. We believe that the streamlining resulted in a leaner, stronger organization.

Sylvamo is subject to a wide range of general and industry-specific laws and regulations that are complex and changing in the regions, countries, states and other jurisdictions where we operate. They include, but are not limited to, laws pertaining to: environmental, health and safety; climate change; tax; privacy and data security; antitrust; product liability; intellectual property ownership and infringement; labor and employment; anti-corruption; import, export and trade; and foreign exchange controls and foreign ownership and investment. In addition, new laws or regulations affecting our facilities are routinely passed or proposed.

We have procedures in place to stay informed about developments concerning possible new legislation and laws in the countries where we operate. We regularly assess whether such legislation or laws may have a material effect on us, our operations and financial condition.

Current or proposed environmental laws (by “laws,” we also mean regulations and other governmental rules) include those governing wood harvesting, air emissions, climate change, waste water discharges, storage, management and disposal of hazardous substances and wastes, contaminated sites, landfill operation and closure obligations, and health and safety matters. Compliance with these laws in all jurisdictions where we operate, therefore, is a significant factor in the operation of our business and may result in capital expenditures as well as additional operating costs. For example, our United States mills are in compliance with the U.S. Environmental Protection Agency’s (“EPA”) maximum achievable control technology (“MACT”)

standards that require owners of specified pulp and paper process equipment and boilers to meet air emissions standards for certain substances. However, as required by the Clean Air Act, the EPA is expected to conduct a Risk and Technology Review (“RTR”) after the application of the MACT standards to determine if the standard was protective enough for human health. It is possible that such review could result in future MACT and RTR regulations that necessitate our making future capital project expenditures to comply with such regulations.

We are subject to the European Union Deforestation Regulation (“EUDR”), which has a compliance deadline of December 30, 2025. The EUDR will require companies trading in wood, cattle, cocoa, coffee, oil palm, rubber and soya, as well as products derived from these commodities such as paper, to conduct extensive diligence on the value chain to ensure the goods do not result from recent deforestation, forest degradation or breaches of local laws in order to trade such products in or from the European Union market. We have incurred costs and devoted significant time and effort to assess how, and to prepare, to comply with the EUDR, and will continue to incur costs and devote time and effort to comply after its requirements go into effect. The EUDR may also reduce the availability of and increase the price of goods supplied to us that are subject to its rules.

Several Canadian provinces, most countries in Europe, and some states in the United States have adopted, and more jurisdictions may adopt, extended producer responsibility, or “EPR,” laws. EPR laws assign producers of the materials covered by the laws some financial responsibility for the end-of-life management of those materials within the adopting jurisdiction. These laws can apply to various types of materials, and some of them apply to packaging and paper products. We are, or in 2025 will be, subject to EPR laws in various European countries, Canadian provinces and states in the United States, including, among others, California, Colorado, Maine, Minnesota and Oregon, where we are or will be required to pay fees to manage the end-of-life cost of our products. EPR laws also may cause us to pay higher prices for the packaging and other materials that we purchase from suppliers subject to EPR laws, who may pass through to their customers some of their increased costs resulting from such laws.

Some of the foregoing and various other environmental and health and safety laws applicable to us provide for substantial fines or penalties and other civil and criminal sanctions for failure to comply. Certain environmental laws provide for strict liability and, under certain circumstances, joint and several liability; for example, for investigation and remediation of the release of hazardous substances into the environment.

We are committed to avoiding adverse impacts on the environment, including by controlling emissions and discharges from our facilities and by responsible sourcing of materials to produce our paper, both as an environmental steward and to maintain our compliance with applicable laws. However, we may encounter situations in which our operations failed to maintain full compliance with applicable requirements, or we may learn that previous owners of our property failed to comply with applicable requirements for which responsibility may be imposed on us by law (for example, if they released substances in violation of environmental laws), which could possibly lead to civil or criminal fines, fees, penalties or enforcement actions against us. These could include governmental or judicial orders that stop or interrupt our operations or that require us to take corrective measures at substantial costs, such as installation of additional pollution control equipment or environmental remediation. See Item 1A. Risk Factors – “We are subject to extensive environmental laws and regulations and could incur substantial costs as a result of compliance with, violations of or liabilities under these laws and regulations.” An environmental clean-up matter in Brazil, which has been ongoing since prior to our spin-off from International Paper, and which has not had, but could have, a material financial impact on us, is described in Note 13 Commitments and Contingent Liabilities to the Consolidated Financial Statements included in Item 8 in this Annual Report on 10-K.

In 2024 we spent approximately $2.5 million and over the course of 2025 and 2026, we expect to spend $14-$15 million on capital projects in the aggregate for our mills in the three regions where we operate to control environmental releases into the air and water and to assure environmentally sound management and disposal of waste. Depending on how project timelines develop, we expect to spend about $6-$12 million of such amount in 2025.

Multiple laws have been passed in various jurisdictions addressing climate change that apply to us and may have a material impact on us.

The Paris Agreement, an international treaty on climate change, went into effect in November 2016 and continues international efforts and voluntary commitments toward reducing greenhouse gas (“GHG”) emissions. Consistent with this objective, participating countries aim to balance GHG emissions generation and sequestration in the second half of this century or, in effect, achieve net zero global GHG emissions. Although the United States has withdrawn from the Paris Agreement, our two mills in Europe and our three mills in Brazil are impacted by GHG reduction commitments made by member countries under the Paris Agreement. In the EU, there is a GHG Emissions Trading System ("EU ETS"). Our Saillat and Nymolla mills are under Phase IV of the EU ETS that established a trading period ending in 2030, during which the two mills may benefit from free allocation of GHG emission allowances.

However, the mills’ continued participation is subject to various factors, including potential changes to the EU ETS system, and our Nymölla mill’s eligibility to participate will terminate on December 31, 2025, absent any governmental action that would allow continued participation. The financial impact on us of such termination will depend in part on factors not within our control, including any governmental action ameliorating the impact of termination. The Paris Agreement and EU ETS may have a material impact on us depending on, among other factors, how binding the GHG emissions reduction commitments made by Paris Agreement member countries are, how market prices for GHG emissions credits evolve under applicable rules over the coming years, and the extent to which our mills are subject to requirements of member countries imposed in connection with the Paris Agreement.

In the United States, the EPA manages regulations to: (i) control GHG emissions from mobile sources by adopting transportation fuel efficiency standards; (ii) control GHG emissions from new Electric Generating Units ("EGUs"); (iii) control emissions from new oil and gas processing operations; and (iv) require reporting of GHG emissions from sources of GHG emissions greater than 25,000 tons per year. Several U.S. states have enacted or are considering legal measures to require the reduction of GHG emissions by companies and public utilities. These federal and state regulations have not had a material impact on us. We monitor proposed programs, but it is unclear what impacts, if any, future GHG rules would have on our operations. Although not required by current regulations, we aim to reduce our Scope 1, 2 and 3 GHG emissions by 35% and define a pathway to net zero emissions by 2030 against a 2019 baseline, although we cannot provide assurance that we will be successful in these efforts.

Furthermore, governments may enact additional laws to protect the environment and address climate change, which could expose us to the costs of additional compliance and the risks of potential noncompliance. Environmental and climate change regulation continues to evolve in the various countries and U.S. states where we do business. For example, some U.S. states in which we have manufacturing operations, including New York, are taking measures to reduce GHG emissions, such as by developing a cap-and-trade program. While it is likely that governmental action and legislation regarding environmental protection and climate change (including GHG emissions) will continue or increase in the future, it is not possible to predict what additional laws relating to environmental protection and climate change may be implemented, which countries, U.S. states or other jurisdictions may adopt such laws, or the extent to which such laws may impact our business; nor is it possible to predict how existing or future laws will be administered or interpreted. In addition to possible direct impacts, such as our costs of compliance and risk of penalties and corrective measures in the event of violations, future laws could impact us indirectly, such as causing us higher prices for transportation, energy and other inputs, as well as generating more protracted air permitting processes, and causing delays and higher costs to implement capital projects.

If and as regulators increase their focus on climate change and other sustainability issues, we have been, or may become, subject to new disclosure frameworks and regulations. For example, the European Parliament adopted the Corporate Sustainability Reporting Directive (“CSRD”), and EU sustainability reporting standards are being developed by the European Financial Reporting Advisory Group, with such standards to be tailored to EU policies building on and contributing to international standardization initiatives. Such reporting will apply not only to local operations in the EU, but under certain circumstances, to entire global companies that have EU operations. The CSRD will require us to begin reporting for European operations in 2026 and for the entire Company globally in 2029, with the option to voluntarily commence reporting for the entire Company earlier than 2029. As another example, the State of California has adopted new climate change disclosure rules that will apply to us because we conduct business in California. Reporting by us under the rules will be required starting in 2026. The SEC announced proposed climate change disclosure rules in March 2021 that are the subject of litigation challenging them. The SEC deferred their effectiveness as a result of such litigation, and the future status of such rules is uncertain, particularly in view of the new U.S. presidential administration. The SEC’s rules were initially proposed to become effective in 2026. Compliance with the CSRD, the California rules and, if implemented, the SEC rules, has required and may continue to require us to incur costs and devote significant resources, time and attention by our management and other personnel. While we expect to fully comply with all such rules as they apply to us, if we fail to comply, it would subject us to potential penalties and fines.

Regional, national, state and local regulations apply to us in Europe, Latin America and North America that regulate the licensing and inspection of our facilities, including, in the United States, compliance with the Occupational Safety and Health Act that sets health and safety standards to protect our employees from accidents, and Department of Labor regulations that set employment practice standards for workers.

We are subject to highly complex tax laws in various countries in Europe, Latin America and North America, most notably in the countries where we have significant operations – Brazil, France, Sweden and the United States – that if violated, could result in significant fines, interest charges and costs associated with litigation.

In Brazil, our business is subject to various tax proceedings, including those discussed in Note 13 Commitments and Contingent Liabilities and Note 12 Income Taxes to the Consolidated Financial Statements included in Item 8 in this Annual Report on 10-K.

Our global operations subject us to complex and evolving privacy and information security laws and regulations such as the EU General Data Protection Regulation, Brazil's Lei Geral de Proteçāo de Dados Pessoais, the California Consumer Privacy Act of 2018 and the California Privacy Rights Act. These laws require us to comply with a range of obligations regarding the handling of personal data. There are significant penalties for non-compliance including monetary fines, disruption of operations and reputational harm. Moreover, governmental authorities around the world are considering, or are in the process of implementing, new data protection regulations. We identify various risks associated with privacy and information security laws and regulations in Item 1A. Risk Factors – “We are subject to information technology risks, including risks related to breaches of security pertaining to sensitive company, customer, employee and vendor information, breaches in the technology used to manage operations and other business processes, and the increasing use of artificial intelligence.”

Our operations around the world are subject to anti-corruption laws and regulations, such as the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act of 2010.

For further information about the regulatory risks of our business, see Item 1A. Risk Factors – “Our business is subject to a wide variety of other laws, regulations and other government requirements that may change in significant ways, and the cost of compliance with such requirements could have a material adverse effect on our business, financial condition, results of operations and cash flows.”

Sylvamo remains committed to operating responsibly and sustainably, and incorporates this into our strategies and everyday processes as we seek to seize opportunities, address risks and create long-term value for our shareholders. Our commitment to sustainability spans our value chain, from the safety of our employees, to the responsible sourcing of raw materials, to using renewable energy and ensuring the recyclability of our products. Our commitment is part of our Code of Conduct and it requires us to operate as responsible stewards for our communities and the environment. We believe that operating in this manner creates healthy communities, enhances our competitive position with our customers, increases our desirability as an investment and helps engender employee pride in the Company, thereby helping us achieve our vision to be the world’s paper company: the employer, supplier and investment of choice.

Our 2023 Sustainability Performance Review (available at sylvamo.com/us/en/sustainability) illustrates our 2023 contributions to the circular, low-carbon economy, to our employees’ safety, well-being and success, and to supporting our communities. It reflects our goal to operate as a sustainable company that generates profits for our shareholders, protects the environment, and improves people’s lives. In the 2023 Sustainability Performance Review, we highlight and report on our key initiatives for achieving that goal. We plan to report on our initiatives for 2024 in our 2024 Sustainability Performance Review, to be published in 2025. Our annual sustainability reporting includes disclosures aligned with the Global Reporting Initiative (“GRI”) and the Task Force On Climate Related Financial Disclosures (“TCFD”) frameworks (available at sylvamo.com/us/en/sustainability/reporting). We cannot guarantee that we will achieve our goals and initiatives described in our Sustainability Performance Reviews and in this Annual Report on Form 10-K. Our ability to achieve them is subject to risks and uncertainties both known and unknown, including various risks noted in Item 1A. Risk Factors and elsewhere in this Annual Report on Form 10-K.

Sylvamo recognizes the environmental, social and economic values of forested landscapes. We seek to play an active role in preventing deforestation and forest degradation, promoting and increasing the use of responsibly managed forests, and meeting market demand for sustainably certified products, through our efforts described below.

In addition to our Code of Conduct, our Environmental, Health, Safety and Sustainability Policy sets forth the principles we follow to ensure the health and safety of all employees, contractors and visitors, improve our environmental impact and our stewardship of natural resources. Our Global Fiber Procurement Policy sets forth requirements for the wood we accept, including requirements intended to protect the environment and rights of indigenous peoples and local communities. Our Third Party Code of Conduct requires the parties with which we do business to comply with all laws and encourages them to reduce their impact on the environment. We make these policies available on our website.

Our operations strive to incorporate responsible forest stewardship to ensure healthy and productive forest ecosystems for generations to come. For example, we promote healthy and productive forest ecosystems by committing to source 100% of our fiber from sustainably managed forests and aiming to conserve, enhance or restore 250,000 acres of ecologically significant forestland globally by 2030. Towards this goal, in 2024 we continued investing in reforestation in the Atlantic Forest region of Brazil and the Appalachians of the United States, through joint efforts with international and local organizations.

We maintain longstanding partnerships with several of the world’s largest and most respected environmental and conservation organizations to restore and protect forests and advance the understanding of the role of forests as natural climate solutions, including the Arbor Day Foundation, the Nature Conservancy, the World Wildlife Fund and various local environmental organizations in the communities where we live and work. We also help our suppliers with their efforts to develop actions that improve forest management and fiber procurement practices. We believe that these strategic informal partnerships are essential to achieve the scale necessary for positive long-term impact and to develop sustainable solutions that address critical regional and global forestry issues.

We support and use third-party certification of sustainable forest management through forest certification and chain-of-custody systems, and we work to continue to meet our customer’s demand for certified-fiber products. Sylvamo follows these credible certification systems: Forest Stewardship Council® (FSC®); the Sustainable Forestry Initiative® (SFI®); and the Programme for the Endorsement of Forest Certification (PEFC). In 2024, all of our sourced fiber followed the FSC® Controlled Wood Standard, and based on the latest figures available, approximately 60% of our sourced fiber was from forests certified to the FSC®, SFI® or PEFC Forest Management Standards. Additionally, nearly all of our owned forestland is certified to the FSC® (C101761) Forest Management Standard.

Sylvamo is working to reduce our water usage by an incremental 25% compared to a 2019 baseline. To that end, in 2024 we conducted a thorough internal water study at our mill in Saillat, France, and shared best practices with our other mills based on the results of the study. We intend to update our progress reducing water usage at least annually on our Company website or in our Sustainability Performance Reviews.

Sylvamo recognizes that the climate is changing. The GHGs carbon dioxide and methane trap higher amounts of heat in the atmosphere than many other atmospheric gasses and remain in the atmosphere for years; therefore, we believe it is prudent to reduce those emissions. We seek to reduce our GHG emissions by working to reduce our Scope 1, 2 and 3 emissions, and by advancing a lower-carbon economy by designing 100% reusable, recyclable or compostable papers that people depend on for education, communication and entertainment. Additionally, various jurisdictions where we operate have passed laws to address climate change that have an impact on us and our work to reduce GHG emissions, as described above in “-Environmental and Other Regulations - Environmental and Climate Change Regulation.”

We seek to achieve an incremental 35% reduction in our mills’ Scope 1, 2 and 3 GHG emissions by 2030, as compared against a 2019 baseline, and continue efforts to further decarbonize our operations by defining a pathway to net zero. Our GHG emissions reduction targets were validated by the Science Based Targets Initiative (SBTi) in April 2023 and are consistent with a well below 2 degrees Celsius scenario and the Paris Agreement. The Paris Agreement impacts our mills in Europe and Brazil, due to GHG emissions reduction commitments in accord with the Paris Agreement that have been made by the respective countries in which those mills are located. Our mills in Europe may benefit from free allocation of GHG emission allowances under the EU ETS to meet GHG emissions reduction targets, subject to various factors, including that our Nymölla mill’s eligibility to participate in allocations is expected to terminate at the end of 2025, as described in “- Environmental and Other Regulations - Environmental and Climate Change Regulation”

Based on the most recent available data, Sylvamo’s mills generated at least 85% of the energy used in the mills from carbon-neutral biomass residuals, which minimizes the use of fossil fuels that our company would otherwise use in its operations. Our mill in Nymölla, Sweden, has EU Ecolabel and Nordic Swan Ecolabel certification, which are third party certifications of products that meet high environmental standards and, in the case of EU Ecolabel certification, contribute to the EU’s goal of climate neutrality by 2050.

Sylvamo participates in the Carbon Disclosure Project (“CDP”) questionnaires concerning climate change, forests and water, to quantify and provide transparency on our environmental practices and progress. We also participate in the EcoVadis rating platform that assesses supply chain environmental, social and ethical practices.

Our responses to CDP questionnaires and our EcoVadis performance overview are published at www.sylvamo.com/us/en/sustainability.

The long-term effects of climate change on the global economy, our industry and us are unclear, especially in view of the political significance and uncertainty around regulatory actions proposed or being taken to address climate change. Changes in climate where we, our customers and our suppliers operate could have an adverse impact on our business, results of operations, and financial condition, as could regulatory actions to address climate change. More information about risks related to climate change and climate change regulation is available in Item 1A. Risk Factors – “We are subject to physical, financial and reputational risks associated with climate conditions and climate change, including global, regional and local weather conditions, the availability of wood fiber, water and fuel, and the impact of increasing regulatory and investor focus on climate change.”

We have a steering team for sustainability matters consisting of a cross functional group of employees and commercial leaders. The team guides the company’s sustainability and community engagement strategies and monitors progress. It is chaired by our Senior Vice President, Chief Administrative and Legal Officer (“SVP CA&LO”), the highest-ranking non-board company executive with direct oversight of climate-related issues, who reports to our CEO. We have a Chief Sustainability Officer (“CSO”) who oversees another team of employees who report to the CSO. The CSO’s team is responsible for our global sustainability strategy and initiatives, which are intended to protect the environment and improve the lives of those we interact with, while creating profit for shareowners. Our CSO reports to our SVP CA&LO. Our CSO provides regular reports to our board’s Nominating and Corporate Governance Committee, which is the board committee responsible for oversight of sustainability matters, including oversight of climate-related matters.

Our sustainability efforts are carried out in all of the regions where we operate, by multiple business teams into whose responsibilities sustainability concepts have been integrated. In addition to the dedicated sustainability team of employees led by our CSO, our human resources and sourcing teams handle various aspects of sustainability programs in their respective areas. Also, designated staff at our corporate, business and facility levels help identify, prioritize and manage sustainability-related risks and opportunities, and we have a responsible operations working group made up of global manufacturing and technical experts who are focused on key operational issues related to water and GHG emissions.

Sylvamo’s internet address is www.sylvamo.com. We make available, free of charge, on or through our internet website, our annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to those reports, as soon as reasonable practicable after we electronically file such material with, or furnish it to, the SEC.

This Annual Report on Form 10-K contains information that includes or is based upon forward-looking statements. Forward-looking statements forecast or state expectations concerning future events. These statements often can be identified by the fact that they do not relate strictly to historical or current facts. They typically use words such as “anticipate,” “assume,” “could,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” “should,” “will” and other words and terms of similar meaning, or they are tied to future periods in connection with discussions of the Company’s performance. Some examples of forward-looking statements include those relating to our business and operating outlook, future obligations and anticipated expenditures.

Forward-looking statements are not guarantees of future performance. Any or all forward-looking statements may turn out to be incorrect, and actual results could differ materially from those expressed or implied in forward-looking statements. Forward-looking statements are based on current expectations and the current economic environment. They can be affected by inaccurate assumptions or by known or unknown risks, uncertainties and other factors that are difficult to predict. Although it is not possible to identify all of these risks, uncertainties and other factors, the impact of the following factors, among others, on us or on our suppliers or customers, could cause our actual results to differ from those in the forward-looking statements: deterioration of global and regional economic, civil and political conditions and trade relations; physical, financial and reputational risks associated with climate conditions and climate change, including adverse environmental events such as floods and fires; reduced demand for our products due to the cyclical nature of the paper industry, the industry-wide secular decline in paper demand, or competition from other businesses; increased costs or reduced availability of the raw materials, energy, transportation (truck, rail and ocean) and labor needed to manufacture and deliver our products; a material disruption at any of our manufacturing facilities; information technology risks including potential cybersecurity breaches affecting us or third parties with which we do business; extensive environmental, tax and other laws and regulations in the Brazil, Europe, the United States and other jurisdictions to which we are subject, including our compliance costs and risk of liability and loss for violations; our reliance on a small number of customers; and the factors disclosed in Item 1A.

Risk Factors, as such disclosures may be amended, supplemented or superseded from time to time by other reports we file with the U.S. Securities and Exchange Commission (the “SEC”), including subsequent annual reports on Form 10-K and quarterly reports on Form 10-Q.

We assume no obligation to update any forward-looking statements made in this Annual Report on Form 10-K to reflect subsequent events or circumstances or actual outcomes.

Sylvamo faces risks in the normal course of business and through global, regional and local events. In addition to the risks and uncertainties discussed elsewhere in this Annual Report on Form 10-K, including in Item 1. Business, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, and Item 1C. Cybersecurity, the following are some important risk factors that we face. The occurrence of any of the following risk factors, or of additional risks and uncertainties not presently known to us or that we currently believe to be immaterial, could cause a material adverse effect on our business, financial condition, results of operations and cash flows. In any such case, the trading price of our common stock could decline. In addition, many of these risks are interrelated and could occur under similar business and economic conditions, and the occurrence of certain of them could in turn cause the emergence or exacerbate the effect of others.

This Annual Report on Form 10-K also contains forward-looking statements and estimates that involve risks and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of specific factors, including the factors described below. See Item 1. Business - Forward-Looking Statements.

Our business is subject to numerous risks and uncertainties, including those described in “Risk Factors” below. The principal risks and uncertainties affecting our business include the following:

•global and regional economic and political conditions and trade relations;

•physical, financial and reputational risks associated with climate conditions and climate change;

•a public health crisis;

•the fluctuating and cyclical nature of paper and pulp supply and demand that periodically results in declines in prices for paper and pulp;

•changes in the cost or availability of raw materials and energy needed to manufacture our products;

•reduced truck, rail and ocean freight availability;

•industry-wide decline in demand for paper and related products;

•competition from other businesses and consolidation within the paper industry;

•material disruptions at one or more of our manufacturing facilities;

•information technology risks, including risk of cybersecurity breaches;

•extensive laws, regulations and government requirements, including those related to the environment and climate change, including costs of compliance and any liabilities under such laws;

•our reliance on a small number of significant customers;

•the significant capital needed for our operations;

•our failure to attract and retain senior management and other key employees;

•a significant write-down of our goodwill or other intangible assets;

•failure to achieve expected investment returns on pension plan assets or regulatory or other factors affecting the plans’ funded level;

•labor disputes;

•inability to achieve expected benefits from strategic corporate actions;

•inability to protect our intellectual property and other proprietary rights;

•loss of commercial agreements with International Paper;

•failure of transactions in connection with our spin-off from International Paper to qualify for non-recognition treatment for U.S. federal income tax purposes;

•satisfaction of indemnification obligations between us and International Paper;

•our indebtedness having a material adverse effect on our financial condition, or our inability to generate sufficient cash to service our indebtedness;

•future offerings of debt or equity securities senior to our common stock, depressing its price;

•if we do not continue to declare dividends, repurchase shares of our common stock or otherwise return capital to shareholders, shareholders must rely on appreciation in our stock’s value for investment returns;

•future issuances of equity, diluting our outstanding common stock;

•a shareholder’s sale of a substantial number of shares of our common stock, causing its price to decline;

•actions of activist shareholders that cause us to incur costs and adversely affect our stock price; and

•provisions in our certificate of incorporation and bylaws that could hinder a change in control of our company, cause a reduction in the price of our stock and limit the forum for actions against, and the liability of, our directors and officers.

We operate in three primary regions, each of which contributes significantly to our financial performance: Europe, Latin America and North America. Five of the seven mills that we own are located outside the United States: three in Brazil, one in France and one in Sweden. Deterioration of economic, civil or political conditions, either globally or in a region where we operate, could have a material adverse effect on our business, financial condition, results of operations and cash flows. As examples, a recession could reduce demand for our products, impact capacity utilization, and erode our profits; significant inflation could increase our costs, reduce demand for our products if we increase prices, and erode our profits; and an unstable economic environment could disrupt our business strategies and destabilize demand for our products. Such conditions could also generally affect industrial non-durable goods production, consumer spending, commercial printing and advertising activity, white-collar employment levels, and consumer confidence, all of which could impact our costs of operating and demand for our products.

Also, civil or political unrest or conflict, including military conflict, could hinder the supply to us of, and increase the cost of, materials needed for our operations. Military conflicts that were ongoing in 2024 could have a material adverse effect on us in the future; for example, if the war in Ukraine were to spread further in Europe, or if, notwithstanding a recent ceasefire, armed conflict in and near the Middle East were to spread or Houthis attacks affecting Red Sea shipping were to recommence and increase in severity. With respect to these specific conflicts, in 2024 we experienced inflation in transportation costs due to shipping disruptions in and around the Red Sea that, in turn, resulted in global increases in shipping and container costs and supply chain disruptions. However, we believe that, generally, our operations in Europe are at more risk than our operations in Latin America and North America from potential expansion of these conflicts, because geographic proximity to such conflicts elevates the risk of transportation network, energy and supply chain disruptions and related price increases.

Other unfavorable economic, political or civil conditions in the three regions where we operate, such as strikes, lack of availability and high cost of credit, and fluctuations in the value of local currency versus the U.S. dollar could adversely affect our cost and ability to manufacture and deliver our products to customers, obtain credit on favorable terms, and maintain profit margins.

The imposition of trade protection measures, such as governmental subsidies and tax benefits, favoring locally produced products that compete with ours, but which do not also protect our products, could have a material adverse effect on our results of operations and business prospects. Conversely, the removal of trade protection measures that protect our products could have a material adverse effect on our results of operations and business prospects. For example, our mills in Brazil have historically benefited from policies favoring domestic producers. We cannot guarantee that any such policies will continue or that we will continue to benefit from existing or future policies, nor can we guarantee that we will not be harmed by future policies.

Disruption in existing trade agreements, or increased trade friction between countries, could result in protective measures such as tariffs and anti-dumping and countervailing duties. Protective trade measures could skew markets and disrupt the cross-border flow of globally traded materials needed to make our products and the distribution of our products. For example, tariffs imposed or proposed by the United States on items that we import into the United States could increase our costs for such items. If we were to increase our products’ prices to mitigate the increase in our costs, it could decrease demand for our products. Also, protective trade measures taken by other countries in response to tariffs imposed by the United States could make our exported products more expensive and less desirable to customers in those countries. The impact on us of tariffs imposed or proposed by the United States or other countries is currently uncertain and depends upon various factors, including the extent to which we would import or export the items subject to the tariffs, the impact of the tariffs on the pricing, distribution and availability of items we import, the impact on demand for products that we export, and whether the negative impact on us of any tariffs imposed on products that we import is ameliorated by the positive impact of any competitive advantage conferred on products that we produce and sell within the same country. One of our significant imports into the United States is energy from Canada, and we export products from the United States to various locations globally, including Mexico. Our products sold within the United States compete with similar imported products and may benefit from tariffs imposed by the United States.

Climate conditions, including those that may be associated with climate change, have the potential to disrupt our business and cause us financial loss. Increases in global average temperatures, which can be caused by increased concentrations of carbon dioxide and other GHGs in the atmosphere, could significantly change weather patterns, including precipitation patterns and growing seasons. An increase in global temperature could also lead to an increase in the frequency and severity of severe weather events and other natural disasters. Changes in weather patterns, severe weather events and other natural disasters pose significant risks for our operations and the operations of our suppliers and customers, including, without limitation, that hurricanes, tornados, hail, fire, extreme precipitation, flooding, snow, ice storms, extreme heatwaves and drought could cause heavy damage to or destruction of our valuable assets and have multiple adverse impacts on our business:

•Decreased productivity of forests, increased frequency and severity of wildfires, heavy rain or drought, inadequate distribution and abundance of tree species, and the spread of disease or insect epidemics in forestlands, could adversely affect timber production and harvesting, thereby reducing the availability to us of, or reducing the density and quality of, the virgin fiber upon which we rely to manufacture our products. Thus, any one or more of these events could significantly increase the costs to manufacture our products and potentially delay or interrupt our manufacturing operations (see “ – Changes in the cost or availability of raw materials and energy used to manufacture our products could have a material adverse effect on our business, financial condition and results of operations”). If occurring in Brazil, such events could further increase the costs that we have been incurring to replenish the trees on our owned and managed Brazil forestlands and to source virgin fiber from third parties for our mills in Brazil, because such forestlands have been producing sub-optimal yields of mature virgin fiber for our operations. Also, as a result of drought in Brazil, in 2024 wildfires burned approximately 1% of our Brazil forestlands. The 2024 wildfires did not have a material impact on us, but if drought and wildfires in Brazil worsen, we could incur further increased costs to source more wood in Brazil from third parties and, if we were unable to source an adequate supply of suitable wood, production at our mills in Brazil could decrease.

•A steady supply of significant volumes of water are necessary to the manufacturing operations at our mills, and weather events interrupting such supply could slow or interrupt our mill operations. For example,as a result of periodic drought conditions in Mogi Guaçu, Brazil, water flow sometimes slows and is interrupted to our mill, slowing operations. Although this has not had a material adverse impact in the past,if there were a severe, extended drought, it could cause production at the mill to be suspended for an unknown period of time. Also, because of the need for a steady supply of water, our mills are located near rivers, exposing them to the risk of floods. A flood at any of our mills could result in severe damage to our assets, require costly repairs and cause the mill to suspend operations.

•Our manufacturing operations rely significantly on a steady supply of energy, and fuel is critical to the transport to us of inputs and the distribution by us of our products. Energy or fuel shortages or delivery disruptions caused by climate-related events, or the transition to a lower-carbon economy, could increase the price of energy needed to manufacture our products, the cost to us of having inputs transported to us, and costs of delivering our products to customers. Disruptions have the potential to cause us to suspend or stop operations until energy or fuel again become available.

•Unpredictable weather patterns or extended periods of severe weather could impact our suppliers and disrupt our supply chain, and thus increase our material costs and potentially delay or stop our operations. They also could impact our customers and result in decreased demand for our products by affected customers.

•Our ability to mitigate the adverse physical impacts of severe weather events and other natural disasters depends in part upon our disaster preparedness and response and business continuity planning, but we cannot guarantee that our disaster preparedness and business continuity planning would adequately mitigate such impacts.

•The introduction of a carbon tax or government mandates to reduce GHG emissions, and more stringent or complex environmental and other permitting requirements, could result in costs to meet such requirements and other additional costs of compliance.

•There is no assurance that we can recover, through increased prices, any increased costs to us of fiber, energy, other materials, manufacturing stoppages or delays, regulatory compliance, or any other factor related to climate conditions or climate change, and if we were to pass these costs on to customers, it could reduce demand for our products.

•There has been an increased focus, including from investors, customers, regulators and other stakeholders regarding climate change, which has resulted or could result in more prescriptive reporting requirements with respect to climate change-related topics and increased expectations and pressure to voluntarily disclose such topics, all of which increase compliance costs. Additional details are available in Item 1. Business “— Environmental and Other Regulations” and “— Sustainability.”

•We have established and publicly disclosed targets, and our progress towards achieving targets, related to certain sustainability matters, including to reduce Scope 1, 2 and 3 GHG emissions. Our sustainability targets are subject to assumptions, risks and uncertainties, many of which are outside of our control. If we cannot meet these targets by 2030, or if they are perceived negatively, including the perception that they are not sufficiently robust or, conversely, are too costly, our reputation could be harmed.

The impact of events resulting from any one or more of these climate-related risks could, directly or indirectly, have a material adverse effect on our business, financial condition, results of operations and cash flows. We are assessing our climate-related risks and determining the best strategies to address identified risks and increase our business’s climate resilience.

Additional discussion of our environmental regulatory risk is included in – “We are subject to extensive environmental laws and regulations, and could incur substantial costs as a result of compliance with, violations of or liabilities under these laws and regulations” and Item 1. Business – Environmental and Other Regulations.

If a public health crisis were to curtail business activities or result in the imposition of governmental restrictions on the general public or on business activities, or were to cause widespread illness among our or our customers’ or suppliers’ employees, it could, in turn, have a material adverse effect on our business, financial condition, results of operations and cash flows. For example, a public health crisis could reduce demand for our paper as a result of school and business closures and increased remote work among the general public, disrupt operations at our mills due to employee attrition, illness, quarantines, government actions or other restrictions, and cause labor shortages, supply chain disruptions and inflation that constrain our operations and increase our costs to operate.

The paper and pulp industry, including the demand for our products, is cyclical. Historically, economic and market shifts, fluctuations in capacity and changes in foreign currency exchange rates have created cyclical changes in prices, sales volume and margins for our products. The length and magnitude of industry cycles have varied over time and by product, but generally reflect changes in macroeconomic conditions and levels of industry capacity. Most of our products are commodities that are available from other producers. While brand recognition and service levels impact the demand for products, because commodity products have few other distinguishing qualities from producer to producer, competition for these products is significantly based on price, which is determined by supply relative to demand. The overall levels of demand for the products that we manufacture, and consequently our sales and profitability, reflect fluctuations in levels of end-user demand, which depend in part on general macroeconomic conditions, competition, including from electronic substitution, and other factors also described in this Item 1A. Risk Factors in “—The industry-wide decline in demand for paper and related products could have a material adverse effect on our business, financial condition, results of operations and cash flows.”

Industry supply of paper and pulp products is also subject to fluctuation, as changing industry conditions have and will continue to influence producers to idle or permanently close individual machines or entire mills or convert them to different products to offset a decline in demand. Any such closures by us would result in significant cash and non-cash charges. In addition, to avoid substantial cash costs in connection with idling or closing a mill, some producers will choose to continue to operate at a loss, sometimes even a cash loss, which could prolong weak pricing environments due to oversupply. As a result, prices for our products are driven by many factors outside of our control, and we have little influence over the timing and extent of price changes, which are often volatile. Our profitability with respect to our products depends on managing our cost structure, particularly wood fiber, chemicals, transportation and energy costs, which represent some of the largest components of our operating costs and can fluctuate based upon factors beyond our control. If the prices or demand for our paper or pulp products decline, or if wood fiber, chemicals, transportation or energy costs increase, or both, our business, financial condition, results of operations and cash flows could be materially adversely affected. See “—Changes in the cost or availability of raw materials and energy used to manufacture our products could have a material adverse effect on our business, financial condition, results of operations and cash flows.”

We rely heavily on the use of certain raw materials (principally virgin wood fiber, caustic soda, starch and water) and energy sources (principally biomass, natural gas, electricity and fuel oil) to manufacture our products. Our profitability has been, and will continue to be, affected by changes in the cost and availability of the raw materials and energy sources we use. Future inflation in the costs of and decreases in the availability of raw materials and energy is not within our control and could increase our costs of production and slow or stop our production.

In 2024, as compared to 2023, we did not experience significant inflation in the costs of raw materials and energy, except for inflation in the cost of virgin wood fiber, driven primarily by tight wood supply in Europe and high wood demand in Latin America. The market price of virgin wood fiber varies based upon demand, availability, source, and the costs of labor and the fuels used in harvesting and transporting the fiber.

The cost and availability of wood fiber can also be affected by weather, climate variations, natural disasters, general logging conditions, geography, human activity and regulatory activity.

An example of regulatory activity that has the potential to decrease the supply of wood fiber available to us are carbon sequestration regulations. Such regulations limit the availability of forestlands for harvest and could increase our cost of wood fiber and potentially create shortages having an impact on our operations. In particular, the EUDR in the European Union, to become effective on December 30, 2025, will prevent companies trading in certain goods and products derived from such goods, such as paper, from selling those products in Europe unless they conduct extensive diligence on the value chain to ensure that the products do not result from recent deforestation, forest degradation or breaches of local laws. The EUDR could decrease the volume of wood supplied in the European Union and increase prices there for wood generally.

Also in Europe, there is a heightened level of sensitivity in the pricing and availability of raw materials and energy from the geopolitical conflicts in Europe, the Middle East and the Red Sea. We cannot predict whether these geopolitical conflicts will cause future increases in the costs of raw materials and energy for our mills, particularly our mills in Sweden and France.

If we were to experience increases in our operating costs for any of the reasons described above, we might be unable to pass on the increases to customers. The commodity nature of our products means that supply and demand primarily determine our ability to increase our prices. Any sustained increase in the prices of raw materials and energy required for our manufacturing operations without any corresponding increase in our product pricing would reduce our operating margins and could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We rely on third parties to transport materials to us used in our operations and to deliver our products to our customers, including transport by third party rail, trucks and ships. If any of these providers fail to deliver materials to us in a timely manner, we could experience delays in our ability to manufacture our products and be unable to meet customer demand. If any of our transportation providers fail to deliver our products to customers in a timely manner, it could result in additional costs to us in order to remedy the untimely delivery. Further, reduced availability of transportation causes inflationary pressure on the prices charged by our transportation providers, increasing our costs of production and delivery to customers. If any of our transportation providers were to cease operations or cease doing business with us, we could be unable to replace them at a reasonable cost. Any of the circumstances described in this paragraph could result in lost sales, increased supply chain costs and damage to our reputation, and have a material adverse effect on our business, financial condition, results of operations and cash flows.

In 2024, we experienced significant inflation in ocean freight rates and, in the second half of the year, supply chain disruptions due to the global impact on shipping of attacks by the Houthis on and near the Red Sea, which reduced container and ship availability in all three regions where we operate, and also, with respect to our Latin American operations, due to congested ports that increased demand for space on ships. We cannot predict whether continued disruption in ocean freight on and near the Red Sea or demand at Brazilian ports will continue or in the future cause us to experience disruptions in our supply chain, increases in our transportation costs or difficulty supplying our customers. Although such events in 2024 caused increases in our costs, it did not have a material adverse effect on our business, financial condition, results of operations or cash flows.

We rely heavily on the sale of paper products, an industry that has experienced, and is expected to continue experiencing, a decline in demand, which could put pressure on our future revenue, profit margin and growth opportunities. The global demand for uncoated freesheet (“UFS”) decreased at 2.4% CAGR from 2019 to 2024 (which includes the COVID-19 pandemic’s atypical impact in 2020 of a 10.2% decline year-over-year), based on third party RISI industry data reporting as of December 2024. This secular decline in demand is due in large part to competing technologies and materials, including the increased use of e-mail and other electronic forms of communication, increased and permanent product substitution, including less print advertising, more electronic billing, more e-commerce, fewer catalogs and a reduced volume of mail.

The secular decline in demand historically has had a material adverse effect on our business, financial condition, results of operations and cash flows. As the use of non-paper alternatives continue to grow, demand for paper products is likely to decline further, which could have a further material adverse effect on our business, financial condition, results of operations and cash flows.

We operate in a competitive environment in Europe, Latin America and North America. Product innovations, manufacturing and operating efficiencies, and marketing, distribution and pricing strategies pursued or achieved by competitors could have a material adverse effect on our business, financial condition, results of operations and cash flows.

In addition, there has been a trend toward consolidation in the paper industry. Consolidation could result in the emergence of competitors with greater resources and scale than ours, which could adversely impact our competitive position. Further, actual or speculated consolidation among competitors, or the acquisition by, or of, our third party service providers and business partners by competitors could increase the competitive pressures faced by us as customers could delay spending decisions or not purchase our products at all.

A material disruption at our corporate headquarters or one of our manufacturing facilities, or involving any of our machines within such facilities, could prevent us from meeting customer demand and reduce our sales, which could have a material adverse effect on our business, financial condition, results of operations and cash flows. Any of our manufacturing facilities, or any of our machines within an otherwise operational facility, could cease operations unexpectedly due to a number of events, including:

• fires, floods, earthquakes, hurricanes or other catastrophes;

• the effect of a drought, reduced rainfall or a flood on any of our mills’ water supply;

• the effect of severe weather conditions on equipment and facilities;

• disruption in the supply of raw materials, including wood fiber, or other manufacturing inputs;

•    information system disruptions or failures due to any number of causes, including cyber-attacks on us or third parties with which we do business;

•    domestic and international laws and regulations applicable to our business and our business partners around the world;

• unscheduled maintenance outages;

• prolonged power failures;

• an equipment failure or damage to any of our paper-making equipment;

• a chemical spill or release of pollutants or hazardous substances;

• explosion of or damage to a boiler or other equipment;

• damage or disruptions caused by third parties operating on or adjacent to one of our manufacturing facilities;

• disruptions in the transportation infrastructure, including roads, bridges, railroad tracks and tunnels; • a widespread outbreak of an illness or any other communicable disease, such as a viral pandemic or other public health crisis;

• failure of our third-party service providers and business partners to satisfactorily fulfill their commitments and responsibilities in a timely manner and in accordance with agreed upon terms;

• labor difficulties; and

• other operational problems.

Our business operations rely upon secure information technology systems for data capture, processing, storage and reporting. Despite careful security and controls design, implementation, updating and independent third-party verification, our information technology systems could become subject to employee error or malfeasance, cyber-attacks, geopolitical events, natural disasters, failures or impairments of telecommunications networks or other catastrophic events.

Also, third parties with which we do business are potential sources of cybersecurity risks. For example, we outsource certain information technology functions that allow access to our information technology systems, which could lead to a compromise of our systems or the introduction of vulnerable or malicious code, resulting in security breaches adversely affecting us or our customers. We have in place third-party cyber risk management to reduce this risk, and many of our agreements with third parties include relevant indemnification provisions. However, we cannot guarantee that our efforts to minimize third-party cyber risk will prevent a third-party cyber incident from occurring that has a material adverse impact on us. Additionally, if we were to experience loss as a result of a third-party cyber incident, we cannot guarantee that we would be able to recover any or all of such loss under any relevant contractual indemnity.

Although in 2024 we did not experience any significant breaches of our information technology systems from cybersecurity attacks, we cannot be certain that the security measures we maintain to protect our information technology systems are able to prevent, contain or detect cyber-attacks, cyber terrorism or security breaches from known or future cyber-attacks. We expect cyber-attacks to continue to increase in sophistication and frequency for a number of reasons, including increases in technology-based products and services used by us and our customers, the growing use of mobile, cloud, and other emerging technologies such as artificial intelligence, and the increasing sophistication and activities of organized crime, hackers, terrorists, nation-states, activists and other external parties. If a cyber-attack against us successfully resulted in network, system, application or data breaches, it could cause us harm, including, but not limited to, interruption of our systems’ availability, cyber criminals’ misuse of our applications, our inability to access applications required for our operations (such that we may be delayed or unable to source materials, manufacture and ship finished goods and account for orders and deliveries), theft of our intellectual property and trade secrets, inappropriate disclosure of confidential company, employee, customer and vendor information, including disclosures in violation of laws, including privacy laws, and our contractual obligations. The loss to us could be significant, including financial losses resulting from remediating damages to our systems, loss from our inability to operate or delays in our operations, lost sales, negative publicity, litigation and government penalties. As a result, such incidents could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We have processes and controls in place to prevent, detect, respond to and mitigate potential cybersecurity breaches. Nonetheless, we could experience significant cybersecurity breaches.

For additional pertinent information, see Item 1C. Cybersecurity.

Artificial Intelligence (“AI”) is increasingly being integrated into applications and systems used by us and third parties with which we do business. The development, adoption and use of AI is in its early stages. We use only limited AI-enhanced tools at the Company, which are approved after review by our information security team. Yet, our employees could use unauthorized AI tools on our systems, notwithstanding that we require only approved software be used, and our vendors and third-party partners could incorporate AI tools into their software or systems with or without disclosing it to us. AI tools not vetted by us may not meet existing or rapidly evolving regulatory or industry standards concerning privacy and data protection, and may result in a loss of intellectual property or confidential information, resulting in fines, litigation, harm to our reputation, and diminished public perception of the effectiveness of our security measures.

Additionally, unapproved AI tools that are faulty or inadequate for the use to which they are put could harm our Company systems or data. We also could incur substantial costs to address and mitigate privacy and data protection violations, to correct errors and data corruption or loss, and to resolve other resulting issues for affected third parties (for example, customers or other business partners who rely on our systems). Additionally, cyber criminals are increasingly using AI to enhance the sophistication and effectiveness of their cyber attacks, which increases our risk of cybersecurity incidents and our cost to protect ourselves against cybersecurity incidents.

We are subject to extensive environmental laws and regulations, and could incur substantial costs as a result of compliance with, violations of or liabilities under these laws and regulations.

We are subject to extensive environmental laws and regulations in Europe, Latin America and North America. Environmental laws and regulations continue to evolve, and we could become subject to increasingly stringent environmental standards in the future, particularly under air quality and water quality laws and standards, including those intended to address climate change discussed at “— We are subject to physical, financial and reputational risks associated with climate change, including the impact of global, regional and local weather conditions, the availability of wood fiber, water and fuel, and the impact of increasing regulatory and investor focus on climate change” and Item 1. Business - Sustainability - Climate Change and Reduction of GHGs. We anticipate continued or increased regulatory activity at the local, state, federal and international levels regarding environmental matters and environmental public policies that have an impact on our manufacturing operations. Compliance with regulations that implement new, more stringent requirements or new public policy could require significant expenditures on our part or even the curtailment of certain of our manufacturing operations.

We have incurred, and expect that we will continue to incur, significant costs complying with applicable environmental laws and regulations. Our environmental expenditures include, among others, those related to air and water quality, waste disposal and the cleanup of contaminated soil and groundwater. See Note 13 Commitments and Contingent Liabilities to the Consolidated Financial Statements included in Item 8 in this Annual Report on 10-K for additional information on environmental matters.

Further, we are required to comply with environmental laws and the terms and conditions of multiple environmental permits. In the countries where we manufacture paper, our industry is subject to various performance-based rules associated with effluent and air emissions. For example, in the United States, federal, state and local laws and regulations require us to routinely obtain authorizations from and comply with the evolving standards of the appropriate governmental authorities, which have considerable discretion over the terms of permits. Failure to comply with environmental laws and permit requirements imposed by a governmental authority having jurisdiction over our operations could result in civil or criminal fines or penalties or enforcement actions, including regulatory or judicial orders enjoining or curtailing our operations or requiring us to take corrective measures, install pollution control equipment, or take other remedial actions, such as product recalls or labeling changes. There can be no assurance that future environmental permits will be granted or that we will be able to maintain and renew existing permits, and the failure to do so could have a material adverse effect on our business, financial condition, results of operations and cash flows.

In addition, as the owner and operator of real property, we could be liable under environmental laws for investigation, cleanup, closure and other costs and damages resulting from the presence and release of hazardous substances on or from our properties or operations, including properties that we no longer own or operate. For example, at our Mogi Guaçu mill in Brazil, we are working with environmental regulators to determine the work necessary to address historic contamination on areas that we own near the mill. See Note 13 Commitments and Contingent Liabilities to the Consolidated Financial Statements included in Item 8 in this Annual Report on Form 10-K for additional information. The amount and timing of environmental expenditures is difficult to predict, and, in some cases, our liability may be imposed without regard to contribution or to whether we knew of, or caused, the release of hazardous substances and may exceed forecasted amounts or the value of the property itself. The discovery of additional contamination or the imposition of additional cleanup obligations at our or third-party sites may result in significant additional costs. Any material liability we incur could preclude us from making capital expenditures that would otherwise benefit our business and have a material adverse effect on our business, financial conditions, results of operations and cash flows.

Environmental and Other Regulations, that increase our costs of operating and, if we fail to be fully compliant, could result in fines, penalties and reputational harm.

Our compliance with existing and new environmental laws, and any future remediation requirements relating to discharges under environmental laws, including, potentially, with respect to an ongoing environmental matter in Brazil (see Note 13 Commitments and Contingent Liabilities to the Consolidated Financial Statements included in Item 8 in this Annual Report on 10-K), could require significant expenditures by us, and there is no assurance that our existing reserves for specific matters will be adequate to cover our future costs. We also could incur substantial fines or sanctions, enforcement actions (including orders limiting our operations or requiring corrective measures), natural resource damages claims, investigation, cleanup and closure costs, and third-party claims for property damage and personal injury as a result of violations of, or liabilities under, environmental laws, regulations, codes and common law. The amount and timing of environmental expenditures is difficult to predict, and, in some cases, liability may be imposed without regard to contribution or to whether we knew of, or caused, a release of hazardous substances.

For more information about risks related to environmental laws, regulations and governmental requirements, see Item 1. Business – Environmental and Other Regulations.

In addition to environmental laws and regulations, as discussed immediately above and in Item 1 Business – Environmental and Other Regulations, our operations are subject to regulation under a wide variety of other laws, regulations and government requirements in Europe, Latin America and North America, including those relating to health and safety, labor and employment, data privacy, taxes, antitrust and competition, trade, and health care. There can be no assurance that laws, regulations and government requirements will not be changed, applied or interpreted in ways that will require us to modify our operations and objectives, affect our returns on investments by restricting existing activities and products or subjecting them to escalating costs, or require us to spend significant amounts to comply.

For example, we are subject to complex and evolving U.S. and international privacy laws and regulations, including those pertaining to the handling of personal data, such as the EU General Data Protection Regulation (“GDPR”), Brazil’s Lei General de Proteção de Dados Pessoais (“LGPD”), and the California Consumer Privacy Act of 2018 (“CCPA”), as amended and expanded by the California Privacy Rights Act (“CPRA”). The GDPR, which applies with respect to all member states of the European Union, and Brazil’s LGPD both establish rules for the collection, use, processing, storage and transfer of personal data and impose significant penalties for noncompliance. The GDPR gives European Union citizens and residents, and the LGPD gives Brazilian data subjects, expanded rights to control their personal data and access to it, and includes requirements with respect to maintaining the security of personal data, limiting the processing of personal data, reporting data breaches and cross-border data transfers. The CCPA, as amended by the CPRA, affords California residents and households expanded privacy protections. Additionally, governmental authorities in these and other jurisdictions may implement new data protection laws and regulations that apply to us.

Improper disclosure of personal data in violation of the GDPR, LGPD, the CCPA or other current or future personal data protection laws could harm our reputation, cause loss of consumer confidence, subject us to government enforcement actions and fines, and result in private litigation against us, which, in turn, could result in loss of revenue, increased costs, liability for monetary damages, fines or criminal prosecution, all of which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Additionally, as new privacy laws and regulations are passed, we could incur additional, potentially significant, compliance costs, including costs to modify our business practices, data processing and security systems. Regulatory authorities could determine that our data handling practices fail to address all the requirements of any new laws or regulations, which could subject us to penalties, litigation and the other fallout from violating privacy laws and regulations that are noted above.

There is no assurance that our security controls over personal data, the training of employees and vendors on data privacy and data security, and the policies, procedures and practices we implement will prevent the improper disclosure of personal data in violation of any privacy laws or regulations.

We are subject to tax laws in Europe, Latin America and North America that are subject to interpretation by taxing authorities, and we are subject to audit by taxing authorities. Additionally, administrative guidance can be incomplete or vary from legislative intent, and therefore the application of some tax law is uncertain. While we believe the positions reported by Sylvamo comply with relevant tax laws and regulations, taxing authorities could interpret our application of certain laws and regulations differently. We are currently subject to tax audits in the United States, Brazil and other taxing jurisdictions around the world. In some cases, International Paper appealed and we have continued to appeal, certain assessments by taxing authorities in the court system, particularly in Brazil. As such, tax controversy matters may result in previously unrecorded tax expenses, higher future tax expenses or the assessment of interest and penalties. See Note 13 Commitments and Contingent Liabilities and Note 12 Income Taxes to the Consolidated Financial Statements included in Item 8 in this Annual Report on Form 10-K.

For example, the Brazilian Federal Revenue Service has challenged the deductibility of goodwill amortization generated in a 2007 acquisition by International Paper do Brasil Ltda., now named Sylvamo do Brasil Ltda. (“Sylvamo Brasil”), a wholly-owned subsidiary of Sylvamo (the “Brazil Tax Dispute”). Sylvamo Brasil’s assessments for the tax years 2007-2015 total approximately $95 million in tax and $235 million in interest, penalties and fees (adjusted for variation in currency exchange rates). After a previous favorable ruling challenging the basis for these assessments, Sylvamo Brasil received other subsequent unfavorable decisions from the Brazilian Administrative Council of Tax Appeals. These decisions are being appealed. The appeal involves several separate cases. In October 2024, at the first level of appeal in the Brazilian federal court system, the court ruled in favor of Sylvamo Brasil in cases covering approximately two thirds of the disputed amounts. The remaining one third of the disputed amounts is still under challenge at the Brazilian administrative court level and was not part of the ruling. The Brazilian tax authorities have appealed the October 2024 ruling, and there is no assurance that Sylvamo Brasil will ultimately prevail. The Brazilian government may enact a tax amnesty program that would allow Sylvamo Brasil to resolve the Brazil Tax Dispute for less than the assessed amount. There is no assurance that any such amnesty program will be enacted or that we will participate. Pursuant to a tax matters agreement between Sylvamo and International Paper, Sylvamo’s payments for any liability in this matter are capped at 40% of the first $300 million of any final settlement amount (up to $120 million). All decisions concerning the conduct of the litigation related to the Brazil Tax Dispute, including as to strategy, settlement, pursuit, abandonment and participation in any tax amnesty program, are and will continue to be made by International Paper. Sylvamo will thus have no control over any decision related to the ongoing litigation. As legally required by the Brazilian federal court, Sylvamo Brasil has provided surety bonds in connection with the Brazil Tax Dispute. Sylvamo Corporation and International Paper have indemnified the provider of the surety bonds for their respective portions of potential liability during the pendency of the appeal in the Brazilian federal court. If Sylvamo Brasil were unable to renew the surety bonds upon their expiration, or if Sylvamo Brasil were unable to provide additional surety bonds as and when required by the Brazilian federal court, Sylvamo Brasil could be required to post acceptable collateral in order to continue the litigation. International Paper has agreed to provide such additional collateral in respect of its portion of the potential liability, on behalf of Sylvamo Brasil. If Sylvamo Brasil were unable to secure any required surety bond, or if International Paper and Sylvamo were unable to provide acceptable collateral for such surety bond, such that we are not able to continue our appeals, or if the Brazil Tax Dispute is resolved unfavorably, the tax and related costs could have a material adverse effect on our business, financial condition, results of operations and cash flows. We cannot predict when resolution of the Brazil Tax Dispute through the Brazilian courts will occur, but estimate that it could take up to an additional nine years.

The pension plans that we maintain for employees in the United States and former employees in the United Kingdom (“U.K.”) are heavily regulated, and changes in the applicable laws and regulations, or interpretations that impact us, could increase our costs of compliance or negatively impact funding. For example, in a 2024 pension plan case in the U.K. (Virgin Media Ltd v. NTL Pension Trustees II), the presiding court invalidated certain pension plan amendments, the earliest being in 1999, on grounds that the U.K.’s statutory process required that any amendments materially changing plan benefits must undergo certain regulatory notifications and actuarial confirmation. As a result of this ruling, all U.K. pension plans (including our U.K. pension plan) are subject to the risk that any plan amendment made since the late 1990s may be void if such statutory process was not followed. The Company is reviewing its archival U.K. pension files to verify that such process was followed and documented for its U.K. pension plan amendments. If for any amendment to our U.K. pension plan the process was not followed, or if we cannot document that it was followed, and if the amendment is void as a result, we may have to revisit benefits paid out under the Company’s U.K. pension plan and make backdated payments to plan members. In such event, there could be a material increase in the Company’s U.K. pension plan liabilities that requires increased Company contributions to make up the difference.

Increases to income tax rates and other tax rates in the jurisdictions in which we operate could have an adverse effect on our business, financial condition and results of operations. Tax laws, regulations and administrative practices in various jurisdictions may be subject to significant change, with or without advance notice, due to economic, political and other conditions, and significant judgment is required in evaluating and estimating our provision and accruals for these taxes. There are many transactions that occur during the ordinary course of business for which the ultimate tax determination is uncertain. Our effective tax rates could be affected by numerous factors, such as changes in tax laws, regulations, administrative practices, principles and interpretations, the mix and level of earnings in a given taxing jurisdiction or our ownership or capital structures. It is difficult to predict whether and when tax law changes will be enacted that would have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our operations are subject to anti-corruption laws and regulations, such as the U.S. Foreign Corrupt Practices Act (“FCPA”), the U.K. Bribery Act of 2010 (“Bribery Act”), France’s Sapin II Act, and other anti-corruption laws in various jurisdictions where we operate. These laws prohibit us and our officers, directors, employees, and agents acting on our behalf from corruptly offering, promising, authorizing, or providing anything of value to foreign officials for the purposes of influencing official decisions or obtaining or retaining business or otherwise obtaining favorable treatment. Our operations are also subject to economic and trade sanctions laws and regulations, such as those administered and enforced by the U.S. Department of Treasury’s Office of Foreign Assets Control, the U.S. Department of State, the U.S. Department of Commerce, the United Nations Security Council and other relevant sanctions authorities. Our global operations may expose us to the risk of violating, or being accused of violating, the foregoing laws and regulations, or other anti-corruption or economic and trade sanctions laws. Such violations could expose us to reputational harm and could be punishable by criminal fines, imprisonment, civil penalties, disgorgement of profits, injunctions, and exclusion from government contracts, as well as other remedial measures. Investigations of alleged violations can be expensive and disruptive.

Although we have implemented anti-corruption policies, procedures and training measures, there can be no guarantee that these policies, procedures, and training will effectively prevent violations by our employees or representatives in the future. Additionally, we face a risk that our business partners may violate the FCPA, the Bribery Act, the Sapin II Act, or similar laws or regulations. Such violations could expose us to liability, and our reputation could be harmed by their violations. Despite our compliance efforts and activities we cannot assure compliance by our employees or representatives for which we may be held responsible, and any such violation could materially adversely affect our reputation, business, financial condition, results of operations and cash flows.

We rely heavily on a small number of significant customers, and if we were to lose one or more of such customers, it could have a material adverse effect on our sales and profitability. For example, our top ten customers represent approximately 41% of our net sales, including one customer that represents approximately 13% of our net sales; see Note 17 Financial Information by Business Segment and Geographic Area to the Consolidated Financial Statements included in Item 8 in this Annual Report on Form 10-K. In particular, because our business operates in a highly competitive industry, we regularly bid for new business or for renewal of existing business. Generally, our customers are not contractually required to purchase any minimum amount of products. Should our customers purchase products in significantly lower quantities than they have in the past, such decreased purchases could have a material adverse effect on our business, financial condition and results of operations.

We are also exposed to risks associated with the ability of our customers to meet their financial obligations to us. The financial viability of our customers is key to maintaining our sales to those customers and their ability to pay for those sales. Any threat to the financial viability of our customers could result in the reduction, delay or cancellation of customer orders and their ability to pay their outstanding receivables with us which could have a material adverse effect on our business, financial condition and results of operations.

In addition, consolidation among our customers could result in changes to the purchasing habits and volumes among our customers and could affect our relationship with our customers. If one of our competitors’ customers acquires any of our customers, we could lose that business. Additionally, as our customers become larger and more concentrated, they could exert pricing pressure on all suppliers, including us. As a result, we could be forced to reduce the prices of our products. The loss or reduction of business from our larger customers, or the renewal of business on less favorable terms, could have a material adverse effect on our business, financial condition and results of operations.

Our operations require substantial capital. We make capital investments, sometimes substantial, primarily to expand and replace existing facilities and equipment, improve our operations, and comply with changes in environmental laws and regulations. Key pieces of equipment in our various manufacturing facilities may, perhaps unexpectedly, need to be repaired or replaced. Increased fixed costs from capital investments or large one-time capital investments could negatively affect our cash flows. In 2025, we will make significant capital investments to enhance and upgrade our manufacturing operations, including a large capital project at our Eastover mill. Additionally, while we expect such projects to result in favorable returns on the capital invested in them, there is no guarantee that they will have the levels of return that we expect. We expect our capital spend in 2025 for all of our mills to be between approximately $220 and $240 million. We also may incur significant costs associated with capital investments that we make to ensure compliance with environmental laws and regulations; see Item 1. Business - Environmental and Other Regulations - Environmental and Climate Change Regulation.

We are led by a strong senior management team that has extensive experience in the paper industry, and we rely upon an extensive and skilled workforce. Our ability to successfully operate our business and our future growth depends, to a significant degree, on the ability to continue to attract and retain senior management with strong leadership experience and relevant knowledge and skills. There is no guarantee that we will be able to continue to attract and retain strong senior management.

Also, as our workforce at our mills ages and retires, we will lose operators and other members of our skilled workforce with 30+ years’ experience, and many of the employees replacing them will have much less tenure. This is due to a large extent on workforce preferences; that is, employee interest in manufacturing jobs with shifts covering 24 hours, seven days per week, has declined, and employees also are more open now to voluntarily leaving their positions and having multiple employers over their career than has historically been the case in our industry. Our training programs are tailored to accelerate training, but it is difficult to replace the number of years of experience our retiring operators and skilled workforce possessed. Although the labor market generally is not as tight as it was in recent years, the market remains tight for labor having the specialized technical and trade skills and experience needed for manufacturing operations at our mill locations. All of these factors drive up our cost of labor and, further, there is no guarantee that we will be able to attract and retain the skilled employees needed to successfully operate our business in the future.

Additionally, we could experience labor shortages if a public health crisis were to affect the supply of labor or ability of employees to work (see “—A public health crisis could have a material adverse effect on our business, financial condition, results of operations and cash flows”) or if our relationships with our employees represented by unions were to deteriorate (see “—We could experience disruptions in operations and increased labor costs due to labor disputes”).

Loss of the services of any members of our senior management team or other key or skilled employees, significant attrition in our workforce, retirements as our workforce ages or the failure to attract and retain qualified persons to serve in management and other positions, could have a material adverse effect on our business and business prospects.

We review our goodwill balance for impairment at least once a year using the qualitative assessment and, when necessary, the quantitative goodwill impairment test allowed in accordance with current accounting standards. Future changes in the cost of capital, expected cash flows, or other factors could cause our goodwill and other intangible assets to be impaired, resulting in a non-cash charge against results of operations to write down these assets for the amount of the impairment. In addition, if we make changes in our business strategy or if external conditions adversely affect our business operations, we may be required to record an impairment charge for goodwill or intangibles, which would lead to decreased assets and reduced net operating results. If a significant write down is required, the charge could have a material adverse effect on our results of operations.

We sponsor various defined benefit pension plans. The assets of the pension plans are diversified in an attempt to mitigate the risk of a large loss. Required funding for our domestic defined benefit pension plan is determined in accordance with guidelines set forth in the federal Employee Retirement Income Security Act of 1974, as amended (“ERISA”) and foreign defined benefit pension plans are funded in accordance with local statutes or practice. Additional contributions to enhance the funded status of the pension plans can be made at our discretion. As of December 31, 2024, the Sylvamo U.K. pension plan was fully funded, and the Sylvamo United States pension plan was 96% funded. We may need to make future contributions to reduce any underfunding and, with respect to the U.K. pension plan, we have agreed with U.K. regulators to contribute to the plan approximately $4 million per year through 2029 to enhance the plan’s self-sufficiency. There can be no assurance that the value of the pension plan assets, or the investment returns on those plan assets, will be sufficient to meet the future benefit obligations of such plans. In addition, during periods of adverse market conditions and declining interest rates, we may be required to make additional cash contributions to the pension plans that could reduce our financial flexibility. Changes in plan demographics, including an increase in the number of retirements or increases in life expectancy assumptions, may also increase the costs and funding requirements of the obligations related to the company’s pension plans. Additionally, interpretations of or changes in laws applicable to our United States or U.K. pension plan could cause us to have to increase funding of the plan; for example, see the disclosure concerning our U.K. pension plan in “— Our business is subject to a wide variety of other laws, regulations and other government requirements that may change in significant ways, and the cost of compliance with such requirements could have a material adverse effect on our business, financial condition, results of operations and cash flows.” An increase in costs or funding requirements could adversely impact our business, financial condition, results of operations and cash flows.

A portion of our workforce is represented by unions and operate under various collective bargaining agreements, including some of our employees that are represented by six unions in Brazil, three unions in France, four unions in Sweden, and a union with two branches representing the hourly employees at our mill in Ticonderoga, New York. We must negotiate to renew or extend any union contracts near or upon their expiration. We may not be able to successfully negotiate new agreements without work stoppages or labor difficulties in the future or renegotiate them on favorable terms. If we are unable to successfully or favorably renegotiate the terms of any of these agreements, or if we experience any extended interruption of operations at any of our facilities as a result of strikes or other work stoppages, this could have a material and adverse effect on our business, financial condition, results of operations and cash flows.

We may pursue strategic acquisitions, joint ventures, divestitures, capital investments and other corporate transactions, such as our acquisition in January 2023 of our paper mill in Nymölla, Sweden. We may not achieve the expected benefits associated with any such transactions in which we engage. Failure to achieve the expected benefits of a transaction could require us to record an impairment charge for goodwill or fixed assets. Among the benefits we would expect from potential acquisitions and joint ventures are synergies, cost savings, growth opportunities and access to new markets (or a combination thereof), and in the case of divestitures, the realization of proceeds from the sale of assets to purchasers who place higher strategic value on such assets than we do. Corporate transactions of this nature which we may pursue involve a number of special risks, including our inability to realize our business goals with respect to such transactions as noted above, the focus of our management’s attention on these transactions and the integration of acquired businesses into our operations, the demands on our financial, operational and information technology systems resulting from acquired businesses, and the possibility that we may become responsible for substantial contingent or unanticipated legal liabilities as the result of acquisitions or other corporate transactions.

In addition, subject to certain exceptions for immaterial transfers, if any portion of the Brazil eucalyptus forest plantations owned by Sylvamo as of October 1, 2021 are directly or indirectly transferred, Sylvamo will be required to make a payment of $100 million to International Paper. For these purposes, a transfer includes any sale, pledge or transfer of any legal or beneficial interest in the Brazil lands, including any grant of an option or other right or interest or entry into any contract that would result in a reduction or diminution of Sylvamo’s economic ownership in the Brazil lands.

A change of control of Sylvamo would also result in the payment becoming due and payable. As a result, we would not realize the full value of any transfer of the Brazil eucalyptus forest plantations, which may make any such transaction less attractive to us, and the provision requiring payment upon a change in control of Sylvamo would be a pricing consideration in any potential strategic transaction.

We rely on a combination of contractual rights with third parties and copyright, trademark, patent and trade secret laws to establish and protect our intellectual property. Although we endeavor to protect our rights, third parties may infringe or misappropriate our intellectual property. We may have to litigate to enforce and protect our copyrights, trademarks, patents, trade secrets and know-how or to determine their scope, validity or enforceability. This would represent a diversion of resources that may be significant and our efforts may not prove successful. The inability to secure or protect our intellectual property assets could harm our reputation and have a material adverse effect on our business and our ability to compete with other companies in our industry. In addition, we have a license from HP Inc. for the right to produce and sell HP branded copy paper in almost all geographies globally. If we were to lose such license, our production volumes could decline and our business, financial condition and results of operations could be materially adversely affected.

In addition, we may be subject to claims by third parties for (i) patent, trademark or copyright infringement, (ii) breach of patent, trademark or copyright license usage rights or (iii) misappropriation of trade secrets. Any such claims or resulting litigation could result in significant expense and liability for damages. If we were found to have infringed or misappropriated a third-party patent or other intellectual property right, we could in some circumstances be enjoined from providing certain products or services to our customers or from utilizing and benefiting from certain patents, copyrights, trademarks, trade secrets or licenses. Alternatively, we could be required to enter into costly licensing arrangements with third parties or implement a costly alternative. Any of these scenarios could harm our reputation and have a material adverse effect on our business, financial condition, results of operations and cash flows.

In connection with our separation from International Paper on October 1, 2021, we and International Paper entered into agreements that govern certain commercial relationships following the separation, including related to the supply and purchase of certain raw materials and finished products, and licenses of certain intellectual property and technology. For example, we entered into offtake agreements related to International Paper’s Georgetown, South Carolina, and Riverdale, Alabama, mills, to provide us with UFS products important to our business.

As of December 31, 2024, we and International Paper, by mutual consent, have terminated the agreement pursuant to which the Georgetown mill supplied the Company with products. The Georgetown mill supplied approximately 250,000 tons to the Company in 2024. After termination of the agreement, we will exit approximately 150,000 tons and, assuming 2024 margins, termination of this agreement is expected to negatively impact the Company’s earnings by $40 million. We retained and qualified approximately 100,000 tons of the most profitable products at our other North American mills.

International Paper has had the right to terminate the offtake agreement related to the Riverdale mill since January 1, 2024, on six months’ advance notice to us, and termination of such agreement could significantly reduce our UFS production capacity in the United States. Such right has not been exercised as of the date of this Annual Report on Form 10-K, but we are preparing for the possibility that the agreement may be terminated. We believe that the Riverdale mill, as a paper mill, is subject to the same or similar economic, external, industry and operational risks that our own mills face (as described in these “Risk Factors”). The expiration or termination of the Riverdale offtake agreement, or the inability of the Riverdale mill to produce our products at a reasonable cost to us or at all, could have an adverse effect on our business, financial condition, results of operations and cash flows if we are unable to acquire or sell the raw materials or finished products to third parties on at least similar terms, or at all.

Moreover, we are required to pay certain fixed costs under the Riverdale offtake agreement regardless of the level of orders received, and we will not be able to terminate the Riverdale offtake agreement until January 1, 2026, even if demand has decreased such that we are no longer able to sell the UFS and other products produced at the Riverdale facility. As a result, until the January 1, 2026 early termination date, we will not be able unilaterally to reduce or eliminate the costs associated with the Riverdale offtake agreement, which may have an adverse effect on our business, financial condition, results of operations and cash flows.

International Paper received a private letter ruling from the U.S. Internal Revenue Service (the “IRS”), and an opinion of a nationally recognized tax counsel, regarding certain aspects of our separation from International Paper, the distribution of shares of Sylvamo and certain related transactions, confirming that such transactions are generally tax-free for U.S. federal income tax purposes to International Paper, Sylvamo and International Paper shareholders. A tax opinion is not binding on the IRS or the courts, and there can be no assurance that the IRS or a court will not take a contrary position. If any of the representations or covenants relied upon for the tax opinion or the private letter ruling are or become inaccurate, are incomplete or are not complied with by International Paper, Sylvamo or any of their respective subsidiaries, the private letter ruling or tax opinion may be invalid in whole or in part, and the conclusions reached therein could be jeopardized.

If the IRS ultimately determines, and a court confirms, that any aspect of the separation, the distribution or any related transaction is taxable, then (i) International Paper could incur significant U.S. federal income tax liabilities and/or (ii) International Paper shareholders that received Sylvamo stock in the distribution could be required to include taxable income or gain with respect to their receipt of Sylvamo stock. Sylvamo may be required to indemnify International Paper for such tax liability in certain circumstances, pursuant to the tax matters agreement; however, there can be no assurance that Sylvamo would have the resources or liquidity needed to satisfy any claim under the indemnity.

Pursuant to the distribution and separation agreement, tax matters agreement and certain other agreements we entered into with International Paper in connection with our separation from International Paper, International Paper agreed to indemnify us for certain liabilities, and we agreed to indemnify International Paper for certain liabilities. Payments that we may be required to make under our indemnity of International Paper are not subject to any cap, may be significant and could negatively impact our business, particularly with respect to indemnities provided in the tax matters agreement.

We may also incur significant costs related to environmental liabilities that may arise at our mills, or other sites that were not owned by International Paper at the time of separation but were primarily operated or used by International Paper’s former printing papers business.

Third parties could also seek to hold us responsible for any of the liabilities that International Paper has agreed to retain. Indemnities from International Paper may not be sufficient to protect us against the full amount of such liabilities if, for example, International Paper is not able to fully satisfy its indemnification obligations. Moreover, even if we ultimately succeed in recovering from International Paper any amounts for which we are indemnified by it, we may be temporarily required to bear these losses ourselves, requiring us to divert cash that would otherwise have been used in furtherance of our operating business. Each of these risks could have a material adverse effect on our financial condition and results of operations.

In 2024, we refinanced our indebtedness to extend its maturity profile and reduce the total amount of our debt facilities. As of December 31, 2024, we have a $400 million cash flow-based revolving credit facility, a $219 million Term Loan A maturing in 2029, a $257 million Term Loan F maturing in 2027, a $232 million Term Loan F-2 maturing in 2031, and a $110 million accounts receivable finance facility maturing in 2027.

As of December 31, 2024, the aggregate principal amount of all of our outstanding debt was approximately $796 million. Our strategy has included a reduction of our outstanding debt obligations, by nearly 48% since 2021, but nonetheless our debt is a risk that could have important consequences to our shareholders, including:

• limiting our ability to obtain additional financing to fund future working capital, capital expenditures, product development, acquisitions or other general corporate requirements;

• requiring a portion of our cash flows to be dedicated to debt service payments instead of other purposes, thereby reducing the amount of cash flows available for working capital, capital expenditures, product development, acquisitions, returning cash to shareowners and other general corporate purposes;

• increasing our vulnerability to general adverse economic and industry conditions;

• increasing our effective tax rate;

• exposing us to the risk of increased interest rates to the extent that our borrowings are at variable rates of interest or upon incurring new debt at maturity at new interest rates;

• limiting our ability to deduct the full amount of the interest payments on any debt from our taxable income;

• limiting our flexibility in planning for and reacting to changes in the industry in which we compete;

• placing us at a competitive disadvantage compared to other, less leveraged competitors or competitors with comparable debt and more favorable terms; and

• increasing our cost of borrowing.

We and our subsidiaries may incur significant additional indebtedness in the future. If new indebtedness is added to our current indebtedness levels, these risks would increase.

Our ability to make scheduled payments on or refinance our anticipated debt obligations will depend on our financial condition and operating performance, which are subject to prevailing economic and competitive conditions and to financial, business, legislative, regulatory and other factors beyond our control, including those discussed under “—Risks Related to Our Industry, the Products We Offer and Product Distribution.” We may not be able to maintain a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness. If our cash flows and capital resources are insufficient to fund our debt service obligations, which would trigger default under the credit agreement, we could face substantial liquidity problems and could be forced to reduce or delay investments and capital expenditures or to dispose of material assets or operations, seek additional debt or equity capital or restructure or refinance our indebtedness. We may not be able to affect any such alternative measures on commercially reasonable terms or at all and, even if successful, those alternative actions may not allow us to meet our scheduled debt service obligations.

The agreements governing our indebtedness contain restrictive covenants that limit our ability to conduct our business, including certain limitations on our ability to dispose of assets and the use of the proceeds from those dispositions, certain requirements that we use the proceeds from future incurrences of debt or issuances of equity to repay existing indebtedness, and limit our ability to incur additional indebtedness. We may not be able to consummate dispositions or to obtain proceeds in an amount sufficient to meet any debt service obligations then due. Our inability to generate sufficient cash flows to satisfy our debt obligations, or to refinance our indebtedness on commercially reasonable terms or at all, could have a material adverse effect on our financial condition and results of operations and our ability to satisfy our obligations under our indebtedness.

A failure to make scheduled payments on our debt, or a breach of any of the covenants under the agreements governing our indebtedness, if not waived by the lenders, or, to the extent applicable, not cured within specified periods, would result in an event of default under those agreements.

Lenders under the agreements governing our indebtedness could declare all outstanding principal and interest to be due and payable, and lenders could further terminate their commitments to loan money under our existing revolving credit facility or foreclose against the assets securing their borrowings, which could force us to file for bankruptcy protection and either restructure or liquidate. Any of these events could result in our shareholders losing some or all of the value of their investments. Further, an event of default may result in the acceleration of any other debt to which a cross-acceleration or cross-default provision applies. In the event the lenders accelerate the repayment of our borrowings, we and our subsidiaries may not have sufficient assets to repay that indebtedness.

In the future, we may decide to issue senior or subordinated debt securities or preferred stock or other equity securities that rank senior to our common stock. Indentures or other instruments governing such securities may include covenants restricting our operating flexibility and ability to pay dividends and make other distributions to our shareholders. Additionally, any convertible or exchangeable securities that we issue in the future could have rights, preferences and privileges more favorable than those of our common stock and could result in dilution to owners of our common stock. We and, indirectly, our shareholders, will bear the cost of issuing and servicing such securities. Because our decision to issue debt or equity securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. Thus, holders of our common stock will bear the risk of our future offerings, reducing the market price of our common stock and diluting the value of their common stock holdings in us.

Since 2022, we have paid quarterly dividends and have been opportunistically repurchasing shares of our common stock. Our continued declaration and payment of quarterly dividends, continued repurchases of shares, and institution of any other return of cash to our shareholders, including payment of any special dividends, will nonetheless be at the discretion of our board of directors and will depend on many factors, including our earnings, financial condition and results of operations, capital requirements, level of indebtedness, covenants contained within our debt agreements, contractual restrictions with respect to payment of dividends and the repurchase of shares, ability to obtain cash or other assets from our subsidiaries, restrictions imposed by applicable law, general business conditions and other factors that our board of directors may deem relevant. As of December 31, 2024, we have repurchased $218 million of the total $300 million authorized thus far by our board of directors for repurchases of our common stock. Any repurchases in excess of the remaining amount authorized for repurchases would require further authorization by our board of directors.

Among the covenants in our debt agreements, prior to the Brazil Tax Dispute (as defined this Form 10-K) being resolved, if we do not maintain the minimum level of liquidity specified in such agreements, or, if there are adverse rulings in the Brazil Tax Dispute and we do not maintain the specified minimum level of liquidity and deposit $60 million into escrow, then we would be limited in the amount of “restricted payments,” including dividends and share repurchases, that we may make while our indebtedness remains outstanding. For more information about the Brazil Tax Dispute and the terms of our indebtedness, see “ – Our business is subject to a wide variety of other laws, regulations and other government requirements that may change in significant ways, and the cost of compliance with such requirements could have a material adverse effect on our business, financial condition, results of operations and cash flows,” and Note 14 Long-Term Debt and Note 12 Income Taxes to the Consolidated Financial Statements included in Item 8 in this Annual Report on Form 10-K.

There can be no assurance that we will continue to pay dividends or repurchase shares of our common stock in the future. Therefore, the success of an investment in shares of our common stock may in the future depend only upon any future appreciation in their value. There is no guarantee that shares of our common stock will appreciate or even maintain their value.

We grant stock-based equity awards to our directors and certain officers and other employees as partial compensation for their services for us. Equity awards dilute shareholders’ ownership in Sylvamo. In addition, we may issue equity as all or part of the consideration paid for acquisitions and strategic investments that we may make in the future or to finance our ongoing operations.

Sales of a substantial number of shares of our common stock in the public market could occur at any time. These sales (or the possibility that these sales may occur), or speculation that a holder of a large number of shares of our common stock intends to sell its shares, could reduce the market price of our common stock. As of February 11, 2025, we have approximately 40.6 million shares of common stock outstanding, of which approximately 6.3 million are subject to certain restrictions on transfer imposed by contract or the U.S. federal securities laws.

We may be the subject of increased activity by activist shareholders. Responding to shareholder activism can be costly and time-consuming, disrupt our operations and divert the attention of management and our employees from executing our business plans. If faced with an activist shareholder in the future, we may not be able or willing to respond to the activist shareholder’s requests, which could result in a proxy contest and disrupt our operations. Activist campaigns could create perceived uncertainties as to the future direction of the Company or its leadership and strategic plans and may also result in the loss of potential business opportunities, harm our ability to attract qualified personnel and business partners and cause us to incur additional legal, financial advisory and other costs. Activist shareholder activity, or the mere presence of an activist shareholder among our investor base, could adversely impact the market price for our common stock or cause periods of significant price volatility.

Our certificate of incorporation and bylaws contain certain provisions that may discourage, delay or prevent a change in our management or change of control, including that they, collectively:

•    authorize the issuance of “blank check” preferred stock that could be issued by our board of directors to thwart a takeover attempt;

• provide that vacancies on our board of directors, including vacancies resulting from an enlargement of our board of directors, may be filled only by a majority vote of directors then in office;

• prohibit shareholder action by written consent, thereby requiring all actions to be taken at a meeting of the shareholders; and

• establish advance notice requirements for nominations of candidates for election as directors or to bring other business before an annual meeting of our shareholders.

These provisions could prevent our shareholders from receiving the benefit from any premium to the market price of our common stock offered by a bidder in a takeover context. Even in the absence of a takeover attempt, the existence of these provisions could adversely affect the prevailing market price of our common stock if the provisions are viewed as discouraging takeover attempts in the future.

Our certificate of incorporation and bylaws could also make it difficult for shareholders to replace or remove our management. Furthermore, the existence of the foregoing provisions could limit the price that investors might be willing to pay in the future for shares of our common stock. These provisions could facilitate management entrenchment that could delay, deter, render more difficult or prevent a change in our control, which may not be in the best interests of our shareholders.

Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for any (1) derivative action or proceeding brought on our behalf, (2) action asserting a claim of breach of a fiduciary duty owed to us or our shareholders by any of our directors, officers, employees or agents, (3) action asserting a claim arising out of or pursuant to the Delaware General Corporation Law (the “DGCL”) or our certificate of incorporation or bylaws, or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware or (4) action asserting a claim governed by the internal affairs doctrine. Unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States of America will, to the fullest extent permitted by law, be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended (the “Securities Act”), the Exchange Act, and the rules and regulations thereunder. Neither this provision nor the exclusive forum provision will mean that shareholders have waived our compliance with federal securities laws and the rules and regulations thereunder, but it does mean that our shareholders are deemed to have notice of and have consented to these provisions concerning choice of forum. The choice of forum provision in our certificate of incorporation may limit our shareholders’ ability to bring a claim in a judicial forum that they find favorable for disputes with us or any of our current or former directors, officers or shareholders, which may discourage lawsuits with respect to such claims. Additionally, a court could determine that the exclusive forum provision is unenforceable. If a court were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable to an action in which we assert the choice of forum, we could incur additional costs associated with resolving the action in other jurisdictions, which could have a material adverse effect on our business, financial condition and results of operations.

Our certificate of incorporation contains provisions permitted under the DGCL relating to the liability of directors and officers. These provisions eliminate a director’s or officer’s personal liability to the fullest extent permitted by the DGCL for monetary damages resulting from a breach of fiduciary duty, except in circumstances involving:

• any breach of the director’s or officer’s duty of loyalty;

• acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law;

• any transaction from which the director or officer derives an improper personal benefit;

• with respect to directors only, Section 174 of the DGCL (unlawful dividends); or

• with respect to officers only, any action by or in the right of the Company.

The principal effect of the limitation on liability provision is that a shareholder cannot prosecute an action for monetary damages against a director or officer unless the shareholder is able to demonstrate a basis for liability for which indemnification is not available under the DGCL. These provisions, however, should not limit or eliminate our rights or any shareholder’s rights to seek non-monetary relief, such as an injunction or rescission, in the event of a breach of a director’s or officer’s fiduciary duty. These provisions do not alter a director’s or officer’s liability under federal securities laws. The inclusion of this limitation on liability in our certificate of incorporation could discourage or deter shareholders or management from bringing a lawsuit against directors or officers for a breach of their fiduciary duties, even though such an action, if successful, might otherwise have benefited us and our shareholders.

Our overall cybersecurity strategy is to:

•Cultivate a security-embedded organization and culture within the Company

•Extend security from technology throughout the Company’s organization, practices and processes (we call this our cybersecurity mesh)

•Evolve our cyber resiliency.

To that end, we have robust cybersecurity risk management processes that include technical security controls, policy enforcement mechanisms, monitoring systems, contractual arrangements, tools and services and management oversight to assess, monitor, identify, detect and manage risks from cybersecurity threats, and to respond to, conduct forensic analysis of, escalate appropriately and report cybersecurity incidents. We proactively obtain intelligence about potential cybersecurity threats, hunt for cybersecurity threats and consistently work to enhance our cybersecurity operations.

We have adopted cybersecurity control principles based on the National Institute of Standards and Technology Cybersecurity Framework (NIST), the Center for Internet Security (CIS) and ISO 27001. Further, our cybersecurity controls are designed to comply with applicable laws concerning protection of private information, including the EU General Data Protection Regulation (GDPR), Brazil’s Lei General de Proteção de Dados Pessoais (LGPD) and the California Consumer Privacy Act of 2018 (CCPA).

In developing and implementing measures to assess, identify and manage cybersecurity risk, our approach is to evaluate the possible operational and financial effects of those measures and take that information into consideration in conducting a risk-based analysis of the appropriate cybersecurity protections for the Company. We strive to protect the Company with cost-effective, efficient and non-disruptive measures, while robustly protecting the Company against cybersecurity threats.

Our cybersecurity protections include physical, administrative and technical safeguards that cover both our information systems (also referred to herein as “information technology” or “IT” systems) and the people with access to our IT systems. We develop, maintain, test and periodically update detailed plans and procedures that are designed to help us prevent, and if necessary, timely and effectively respond to, cybersecurity incidents, which provide for the appropriate Company personnel and management to be involved depending on the type and severity of the incident.

Our IT systems architecture is embedded with cybersecurity features. We utilize a range of third-party software providing layers of defense against cyberattacks, and we have employees and consultants whose jobs are to continually assess and reduce the potential attack surface, to monitor, detect and respond in near real time to incidents to minimize damage, and to enhance the security environment and scale with business needs as they evolve. We conduct continuous monitoring of our potential cybersecurity vulnerabilities and attack vectors.

Our IT systems are accessible by our employees and certain third parties as necessary and appropriate to perform services for or otherwise do business with us. We strictly limit access to our IT systems, including that we use authentication controls and conduct real-time monitoring of access.

We address the cybersecurity threat risk posed by employees and third parties with access to our IT systems, including that we integrate cybersecurity risk management into the culture of our organization by: maintaining policies addressing various aspects of security necessary to protect our IT assets and data; requiring cybersecurity awareness and training programs for persons with access to our IT systems to build their cybersecurity skills and knowledge; consistent messaging to our employees (including from our top leadership) of the importance of managing cybersecurity risk, participating in our cybersecurity training and following our cybersecurity policies; routinely testing responses by our employees to mock efforts to breach our cybersecurity protections; and policies and procedures to follow in the event a cyber breach were to occur at the Company, including in response to the breach and to evaluate the level and materiality of the breach.

We partner with and build relationships with third parties who have access to our IT systems to support an overall ecosystem around cybersecurity that we believe helps reduce third party cybersecurity risk affecting our level of cybersecurity risk. We assess cybersecurity risk from our suppliers and service providers and have in place oversight processes to identify and manage such risks, including that we have systems that constantly monitor each third party with access to our systems and that allow such third parties to see and resolve their risks while we continue to monitor. Our processes to protect against third party cybersecurity risk are cross-functional and form part of our enterprise risk management program, and they are supported by our security, compliance and sourcing organizations. We require suppliers and service providers identified as potential cybersecurity risks to adopt security-control principles based on NIST or similar global standards, and our form contracts for them include provisions drafted to reduce the cybersecurity risk that they may pose for us. We obtain various Service Organization Control 1 and 2 reports from third parties relating to physical security, information security, account administration, transactional processing and reconciliation, client reporting and layers of electronic security controls. Notwithstanding our cybersecurity controls that cover third parties, because it is more difficult to control and mitigate risk associated with third parties than risk internal to our own organization, we believe that these relationships with third parties create additional exposure to cyber risk.

In the event of a cybersecurity breach, our readiness, responsiveness and resiliency are critical. As part of our continuing efforts to assess and enhance our readiness and responsiveness, we conduct periodic mock practice scenarios in which participants at various levels of the Company — including employees responsible for responsive actions in the event of a breach, IT technical personnel and members of senior management — play out responses to various cybersecurity breach scenarios. Thereafter, we debrief and identify areas of improvement, to continually develop response capabilities and processes that are as efficient and that operate as quickly as possible in the event of a breach, to reduce potential harm that could be caused by inefficiencies and delay. Additionally, we regularly assess our systems’ resiliency and recovery capabilities in case of a cybersecurity breach, both self-managed as well as by qualified third parties.

Furthermore, our approach to improving readiness for potential cybersecurity breaches is designed to be integrated and coordinated among all aspects of the cybersecurity incident management lifecycle, including that we assess and consistently work to improve our site-level emergency response, our technology and cyber incident response, our executive-level crisis management, our business and operational continuity, our IT resilience and our disaster recovery. These efforts also take into account and balance against cybersecurity risk our Company’s business needs and operations, and to inform ourselves in conducting this balancing, we obtain input from appropriate employees from our affected business operations, enterprise risk management, business continuity, business operations, information technology and cybersecurity organizations.

To enhance our cybersecurity risk management, we leverage industry associations, third-party benchmarking, audits, threat intelligence feeds and other similar resources, which inform our cybersecurity efforts and help us determine how best to allocate resources. We utilize third-party service providers to assist us in assessing, enhancing, implementing, monitoring and testing our cybersecurity program, areas of cyber risk and cyber risk management.

A cybersecurity threat resulting in a material cybersecurity incident could materially affect us and our business strategy, results of operations and financial condition, especially if it causes one or more of the following to occur: our incurring substantial costs to resolve the incident and address legal, reputational and other fallout from the incident; one or more of our IT systems become unavailable to operate our business; unauthorized third parties gain access to our sensitive and confidential business information; we lose access to information on our IT systems necessary to operate our business; and our customers’ and suppliers’ trust in our ability to protect their information is damaged to the extent that it impairs our ability to do business with them.

While we have a cybersecurity program designed to protect and preserve the integrity of our information systems, there is no guarantee that our cybersecurity program will be sufficient to prevent or mitigate the risk of a cyberattack or the potentially serious reputational, operational, legal or financial impacts that may result. We have experienced cybersecurity incidents in the past that were not material, but future incidents could have a material impact on our business strategy, results of operations, financial condition, cash flows and reputation. See “We are subject to information technology risks related to breaches of security pertaining to sensitive company, customer, employee and vendor information, breaches in the technology used to manage operations and other business processes, and the increasing use of artificial intelligence” in Item 1A, “Risk Factors” in this Annual Report on Form 10-K.

Our board of directors has overall responsibility for risk management oversight, with its committees assisting the board in performing this function based on their respective areas of expertise. Our board oversees cybersecurity matters and risk, and the Audit Committee also oversees risk that includes cybersecurity risk.

The board periodically reviews our processes for assessing and addressing key strategic, operational, compliance and risk management matters concerning cybersecurity, and as part of such assessment receives briefings on such matters from our Chief Information Security Officer (“CISO”). These briefings include reports on the threat landscape, our strategies, efforts and investments to address threats, and updates on incidents. The Audit Committee also receives reports from the Company’s Vice President of Internal Audit assessing internal controls that include cybersecurity controls. Furthermore, our cybersecurity risk management processes are integrated into our enterprise risk management program and our compliance risk management program, both of which are also overseen by our board.

Our CISO has approximately 21 years of experience in the cybersecurity industry. She is responsible for developing, coordinating and overseeing our cybersecurity strategy, policy, program and solutions, and for providing cybersecurity guidance to key management and internal company oversight bodies. Our CISO manages our cybersecurity organization, which covers all regions in which we operate and which is staffed with employees dedicated full-time to cybersecurity. Our CISO reports directly to our Chief Information Officer (“CIO”) and reports on cybersecurity at least quarterly to senior management and semi-annually to the full board of directors, or more often as needed.

Our CISO is a standing member of our Enterprise Risk Council, which seeks to strengthen our company’s processes with respect to the identification, assessment, management and monitoring the risks most likely to impact our strategic success, including cybersecurity risk. The council is chaired by our VP, Internal Audit, and its members are employees drawn from various areas of our organization. The council meets at least quarterly or more often as needed, to further strengthen risk management activities across the Company, including the risk of cybersecurity incidents.

Cybersecurity threats and incidents are monitored and addressed through the processes described above in “- Risk Management and Strategy” and, as part of such processes, cybersecurity incidents are evaluated by the company’s cybersecurity organization, which escalates information about incidents, as appropriate for the severity of the incident, to the CISO and by the CISO to senior leadership.

The CISO informs, as appropriate, the Enterprise Risk Council, the CIO, the Company’s senior leadership and, as noted above, the board of directors and its Audit Committee, on safeguards to prevent, detect, mitigate and remediate cybersecurity incidents. The CIO and CISO both report directly on a regular basis to the Company’s senior leadership on progress towards specific IT risk management objectives, with the CISO focusing on cybersecurity objectives.

As of December 31, 2024, the Company owned or managed approximately 250,000 acres of forestlands in Brazil. All owned lands in Brazil are independently third-party certified for sustainable forestry under the Brazilian National Forest Certification Program (“CERFLOR”) and the Forest Stewardship Council (“FSC”). As of December 31, 2023, a third party estimated the fair value of our owned forestlands at 4.8 billion reais (approximately $800 million adjusted for variation in currency exchange rates).

Our portfolio of properties spans three continents and includes six vertically-integrated mills and one non-integrated mill with an aggregate annual paper and pulp production capacity of 3.3 million short tons. We have two mills in our North America segment in the United States (Ticonderoga, New York and Eastover, South Carolina), three mills in our Latin America segment in Brazil (Três Lagoas, Mato Grosso do Sul, and Luís Antônio and Mogi Guaçu, São Paulo), and two mills in our Europe segment (Saillat, France and Nymölla, Sweden). Our paper manufacturing operations are further supported by an offtake agreement with International Paper (subject to their earlier termination) for paper production at the North American Riverdale, Alabama, mill for 350,000 short tons of uncoated freesheet. A listing of our production facilities by segment, the vast majority of which we own, can be found in Appendix I hereto, which is incorporated herein by reference.

ITEM 3. LEGAL PROCEEDINGS

The Company may be involved in legal proceedings arising from time to time in the ordinary course of business. The Company is not involved in any legal proceedings, individually or in the aggregate, that we expect to result in a material adverse effect upon our financial condition or results of operations. See Note 12 Income Taxes and Note 13 Commitments and Contingent Liabilities of the Notes to our Consolidated Financial Statements included elsewhere in this Annual Report on Form 10-K, which notes are incorporated into this Item 3, Legal Proceedings, by reference.

Item 103 of Regulation S-K requires disclosure of certain environmental matters when a governmental authority is a party to the proceedings and the proceedings involve potential monetary sanctions, unless we reasonably believe the monetary sanctions will not equal or exceed a threshold of $1 million (which is the threshold we elected to use as permitted by this regulation). The environmental matters set forth in Note 13 Commitments and Contingent Liabilities to the Consolidated Financial Statements included in Item 8 in this Annual Report on 10-K are disclosed in accordance with such requirement and incorporated herein by reference.

The Company’s common stock is traded on the New York Stock Exchange (NYSE: SLVM). As of February 14, 2025, there were approximately 5,010 record holders of common stock of the Company. This number does not include an indeterminate number of “street” holders whose shares of common stock of the Company are held of record by banks, brokers and other financial institutions.

Our Board of Directors approved a quarterly cash dividend of $0.30 per share of the Company’s common stock payable for our first quarter of 2024. They increased the quarterly dividend to $0.45 per share beginning with the dividend payable for our second and continuing though the fourth quarter of 2024. We expect to continue to pay regular quarterly cash dividends in the foreseeable future, though each dividend payment (regular or special) is subject to review and approval by our Board of Directors in its sole discretion. Our ability to pay dividends is, and in the future will continue to be, dependent on the then existing conditions, including our financial condition, results of operations, capital requirements, legal and contractual limitations (including covenants in our agreements governing our indebtedness) and other factors our Board of Directors deems relevant.

On May 18, 2022, the Board approved a share repurchase program under which the Company may purchase up to an aggregate amount of $150 million of shares of its common stock (the “Repurchase Program”). In the third quarter of 2023, the Board authorized an additional $150 million for the Repurchase Program, bringing the total program capacity to $300 million, of which $82 million remains available for repurchases. Pursuant to the Repurchase Program, the Company may repurchase in amounts, at prices and at such times as it deems appropriate, subject to market conditions and other considerations, including all applicable legal requirements. Repurchases may include purchases on the open market or privately negotiated transfers, under Rule 10b5-1 trading plans, under accelerated share repurchase programs, in tender offers and otherwise. The Repurchase Program does not obligate the Company to acquire any particular amount of shares of its common stock and may be modified or suspended at any time at the Company’s discretion. The Company repurchased $68 million of shares during the year ended December 31, 2024.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our audited consolidated financial statements and related notes included in Item 8. Financial Statements and Supplementary Data of this Annual Report on Form 10-K. In addition to historical consolidated financial information, the following discussion contains forward-looking statements that reflect our plans, estimates, and beliefs that involve significant risks and uncertainties. Our actual results could differ materially from those stated and implied in any forward-looking statements. Factors that could cause or contribute to those differences include those discussed below and elsewhere in this Annual Report on Form 10-K, particularly under the headings “Risk Factors” and “Forward-Looking Statements.”

The following generally discusses 2024 and 2023 items and year-to-year comparisons between 2024 and 2023. Discussion of historical items in 2022, and year-to-year comparisons between 2023 and 2022, can be found in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, filed with the SEC on February 21, 2024, under Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The consolidated financial statements have been prepared in United States (“U.S.”) dollars and in conformity with accounting principles generally accepted in the United States (‘‘U.S. GAAP’’) and may not be indicative of the Company’s future performance.

Full-year 2024 net income was $302 million ($7.18 per diluted share) compared with $253 million ($5.93 per diluted share) for 2023. Net sales increased to $3.8 billion in the current year compared with $3.7 billion in 2023. Cash from continuing operations was $469 million in the current year compared to $504 million in the prior year. Adjusted EBITDA was $632 million in 2024, which represents an increase of $25 million from the prior year adjusted EBITDA of $607 million. Additionally, our 2024 adjusted EBITDA margin was 16.8% compared to 16.3% in the prior year and free cash flow was $248 million compared to $294 million last year.

Comparing our performance in 2024 to 2023, higher volumes were driven by stronger demand for uncoated freesheet across all three of our regions. Unabsorbed fixed costs due to economic manufacturing downtime in Europe and North America declined significantly in 2024. These factors, in addition to more favorable input costs and lower planned maintenance outages, were partially offset by lower price and mix and less favorable operations. We generated solid free cash flow again this year. We generated $248 million in free cash flow, repaid $154 million in debt, and returned $130 million in cash to shareholders. Additionally, we reinvested $221 million across our manufacturing network and our Brazil forestlands to strengthen our low-cost position. We also accelerated the development of high-return capital project investments.

Looking ahead to 2025, we remain committed to generating strong adjusted EBITDA and free cash flow while returning cash to shareowners. Our financial results for the three full years since spin-off have established a solid track record and are indicative of our ability to navigate industry conditions, geopolitical events and other uncertainty that we may face. We are confident in our ability to continue to create value for our customers and shareowners.

On January 2, 2023, the Company completed the previously announced acquisition of Stora Enso’s uncoated freesheet paper mill in Nymölla, Sweden. Sylvamo accounted for the acquisition under ASC 805, “Business Combinations” and the Nymölla mill’s results of operations are included in Sylvamo’s consolidated financial statements from the date of acquisition. See Note 7 Acquisitions to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for further details.

During the second quarter of 2022, management committed to a plan to sell the Company’s Russian operations (which were sold on October 2, 2022). As a result, all historical operating results of the Company’s Russian operations have been classified as “Discontinued operations, net of taxes” in the consolidated statements of operations and the notes to the consolidated financial statements. In October 2022, the Company completed the sale of its Russian operations to Pulp Invest Limited Liability Company, a company incorporated in the Russian Federation. See Note 8 Divestiture and Impairment of Business to our financial statements included elsewhere in this Annual Report on Form 10-K for further details.

When reading our financial statements and the information included in this Annual Report on Form 10-K, it should be considered that we have experienced, and continue to experience, several material trends and uncertainties that have affected our financial condition and results of operations and that could affect future performance. We believe that the following material trends and uncertainties are important to understanding our business.

The Company’s operating results are typically closely tied to changes in the general economic conditions in Europe, Latin America and North America, as well as general global economic conditions. The Company’s profitability and operating results are dependent on the price of our products and the market price of raw materials (primarily wood fiber and chemicals), energy sources and third-party transport of our goods. Historically, economic and market shifts, inflationary pressures, fluctuations in capacity and changes in foreign currency exchange rates have created changes in prices, sales volume and margins for our products.

Factors that impact the demand for our products include general macroeconomic conditions, consumer preferences, movements in currency exchange rates, consumer spending, commercial printing and advertising activity, adoption of electronic mediums, and white-collar employment and the shift to hybrid work models.

The Company’s reportable business segments, Europe, Latin America and North America, are organized by geography and are consistent with the internal structure used to manage these businesses. Each of our segments derive their revenue from the manufacture and sale of paper and pulp products. The following summary describes the products and services offered in each of the segments as of December 31, 2024:

Our Europe segment produces a broad portfolio of uncoated freesheet papers for numerous uses and applications, and market pulp. We operate two integrated mills in the region, one in Saillat, France and one in Nymölla, Sweden. Located in the Limousin region of France, the Company’s Saillat mill produces both paper and market pulp. It is the only mill in France to cover the entire production process from wood harvesting to paper, and is one of the leading cutsize producers in France and Western Europe. The Saillat mill produces UFS papers, such as copy paper, and value-added products such as tinted paper and colored laser printing paper under leading brands such as REY Adagio and Pro-Design. We also produce graphic and high-speed inkjet printing papers under the brand Jetstar. The Saillat mill has some of the highest environmental credentials for our products. In January 2023, the Company acquired a paper mill in Nymölla, Sweden. The integrated mill has two pulp lines and the capacity to produce approximately 500,000 short tons of uncoated freesheet on two paper machines. The mill produces several brands, including Multicopy, and paper used for office printing, business forms, digital printing, offset for printing books and much more. The Nymölla mill has an excellent environmental footprint, which complements Sylvamo’s purpose to produce paper in the most responsible and sustainable ways.

Our Latin American operations focus on uncoated freesheet paper and market pulp, supported by the management of approximately 250,000 acres of certified eucalyptus forestlands in Brazil. With a total uncoated freesheet paper capacity exceeding 1.1 million short tons, our three mills in Brazil serve both regional and international markets, being a key supplier in Latin America and a solid global exporter, reaching customers in over 130 countries. Our portfolio includes market-leading brands such as Chamex and Chamequinho copy papers, widely recognized by consumers and distribution channels for their superior quality. Additionally, Chambril offset papers are trusted by printers and converters for their versatility and reliability across various applications. Chambril is available in a wide range of basis weights and specifications to meet the demands of books, notebooks, inserts, leaflets, and industrial end-use requirements. All the products are primarily made from sustainably sourced eucalyptus, which is cultivated and harvested in less than seven years. Latin America operations combine sustainable forestry practices, operational excellence, strong brands and global distribution network.

The North American paper business manufactures uncoated freesheet papers at its mills in Eastover, South Carolina and Ticonderoga, New York and has an offtake agreement to purchase the uncoated papers produced by International Paper’s Riverdale mill in Selma, Alabama. The North American papers business comprises three product lines, Imaging Papers, Commercial Printing Papers and Converting Papers. The imaging papers business, which comprises roughly half of the North American segment’s volume, produces copy paper for use in copiers, desktop and laser printers and digital imaging. These products are important for office use, home office use and in businesses such as education, healthcare and financial services. The commercial printing business comprises about 13% of the North American segment’s volume, and end-use applications in the commercial printing business include advertising and promotional materials such as brochures, pamphlets, greeting cards, books, annual reports and direct mail. The converting business manufactures a variety of grades that are converted by our customers into envelopes, tablets, business forms, file folders and several specialty grades. Uncoated papers are sold under private label and brand names that include Hammermill®, Springhill®, Williamsburg, Accent®, DRM® and Postmark®.

Management provides business segment operating profit, a non-GAAP financial measure, to supplement our GAAP financial information, and it should be considered in addition to, but not instead of, the financial statements prepared in accordance with GAAP. Management believes that business segment operating profit provides investors and analysts useful insights into our operating performance. Business segment operating profit is reconciled to Income from continuing operations before income taxes, the most directly comparable GAAP measure. Business segment operating profit may be determined or calculated differently by other companies and therefore may not be comparable among companies.

The following table presents a comparison of income from continuing operations before income taxes to business segment operating profit:

The following tables present Sales and Operating profit (loss), which is the Company’s measure of segment profitability, for each of the Company’s segments. See Note 17 Financial Information by Business Segment and Geographic Area to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for more information on the Company’s segments.

For the year ended December 31, 2024, our Europe segment sales decreased $20 million compared to the same period in 2023, primarily due to lower sales price and mix ($58 million) which more than offset higher volumes ($39 million).

Europe operating profit for the year ended December 31, 2024 was $35 million higher than the same period in 2023 as lower planned maintenance outages ($26 million), lower unabsorbed costs due to economic downtime ($27 million), lower operating costs ($11 million), lower input costs ($16 million), primarily for chemicals, and higher volumes ($13 million) more than offset the impact of lower sales price and mix ($58 million).

For the year ended December 31, 2024, our Latin America segment sales decreased $32 million compared to the same period in 2023, primarily driven by lower sales price and mix ($35 million) and significant unfavorable foreign exchange impacts which were partially offset by higher volumes ($39 million).

Operating profit for Latin America for the year ended December 31, 2024 was $47 million lower than the same period in 2023, primarily driven by the impact of lower sales price and mix ($34 million), higher operating costs ($18 million) and higher planned maintenance outages ($9 million) which more than offset higher volumes ($9 million) and lower input costs, primarily for chemicals and pulp ($5 million).

For the year ended December 31, 2024, our North America segment sales increased $78 million, compared to the same period in 2023, primarily driven by higher volumes ($145 million) which more than offset lower sales price and mix ($68 million).

Operating profit for North America for the year ended December 31, 2024 was $24 million higher than the same period in 2023 as higher volume ($45 million), lower unabsorbed costs due to economic downtime ($56 million) and lower input costs, primarily for chemicals, wood and distribution ($20 million), more than offset lower sales price and mix ($68 million), higher operating costs ($28 million) and slightly higher planned maintenance outages ($1 million).

Management provides Adjusted EBITDA, a non-GAAP financial measure, to supplement our GAAP financial information, and it should be considered in addition to, but not instead of, the financial statements prepared in accordance with GAAP. Management uses this measure in managing the operating performance of our business and believes that Adjusted EBITDA provide investors and analysts meaningful insights into our operating performance and is a relevant metric for the third-party debt. Adjusted EBITDA is reconciled to Net income, the most directly comparable GAAP measure. Adjusted EBITDA may be determined or calculated differently by other companies and therefore may not be comparable among companies.

Free cash flow is a non-GAAP measure and the most directly comparable GAAP measure is cash provided by operating activities from continuing operations. Management believes that free cash flow is useful to investors as a liquidity measure because it measures the amount of cash generated that is available, after reinvesting in the business, to maintain a strong balance sheet and service debt, and return cash to shareholders. It should not be inferred that the entire free cash flow amount is available for discretionary expenditures. By adjusting for certain items that are not indicative of the Company’s ongoing performance, free cash flow also enables investors to perform meaningful comparisons between past and present periods.

The following are reconciliations of cash provided by operating activities from continuing operations to free cash flow:

The non-GAAP financial measures presented in this Annual Report on Form 10-K as referenced above have limitations as analytical tools and should not be considered in isolation or as a substitute for an analysis of our results calculated in accordance with GAAP. In addition, because not all companies utilize identical calculations, the Company’s presentation of non-GAAP measures in this Annual Report on Form 10-K may not be comparable to similarly titled measures disclosed by other companies, including companies in the same industry as the Company.

Our ability to fund the Company’s cash needs depends on our ongoing ability to generate cash from operations and obtain financing on acceptable terms. Based upon our history of generating strong operating cash flow, we believe we will be able to meet our short-term liquidity needs. We believe we will meet known or reasonably likely future cash requirements through the combination of cash flows from operating activities, available cash balances and available borrowings through the issuance of third-party debt, as needed.

A major factor in our liquidity and capital resource planning is our generation of operating cash flow, which is highly sensitive to changes in the pricing and demand for our products. While changes in key operating cash costs, such as raw materials, energy, mill outages and distribution expenses do have an effect on operating cash generation, we believe that our focus on commercial and operational excellence, as well as our ability to manage costs and working capital, will provide sufficient cash flow generation.

The terms of the agreements governing our debt contain customary limitations as well as other provisions. These provisions may also restrict our business and, in the event we cannot meet the terms of those provisions, may adversely impact our financial condition, results of operations or cash flows.

Cash provided by operating activities from continuing operations totaled $469 million for the year ended December 31, 2024, compared with cash provided by operating activities from continuing operations of $504 million for the year ended December 31, 2023. The decrease in cash provided by operating activities from continuing operations in 2024 relates primarily to changes in working capital which was partially offset by higher net income.

Cash used for working capital components (accounts and notes receivable, inventories, accounts payable and accrued liabilities, and other) was $8 million for the year ended December 31, 2024, compared with cash provided by working capital components of $85 million for the year ended December 31, 2023. Working capital components for the year ended December 31, 2024 primarily reflect $47 million of cash used for accounts and notes receivable and $28 million cash used for other operating activities. This activity was offset by $25 million of cash provided by inventories and $42 million of cash provided by accounts payable and accrued liabilities.

The total cash outflow from investing activities from continuing operations for the year ended December 31, 2024 decreased from the year ended December 31, 2023, primarily due to the purchase of the Nymölla mill which occurred in the prior year.

The following table shows capital spending by business segment, which represents the most significant portion of our recurring investment activities.

Capital spending primarily consists of purchases of machinery and equipment and reforestation related to our global mill operations. As a percentage of depreciation, amortization and cost of timber harvested, capital spending totaled 139% and 147% for the years ended December 31, 2024 and 2023, respectively.

Cash used for financing activities from continuing operations for the year ended December 31, 2024 primarily reflects the payments of $218 million, $49 million, $35 million, $10 million, and $3 million on our outstanding principal debt balances for Term Loan F, Term Loan A, the AR Securitization, Revolving Credit Facility, and Term Loan F-2, respectively. Additionally, payments of $93 million were made to redeem, at a premium, the full value of our 7.00% Senior Notes and pay $5 million in debt issuance costs in connection with the debt refinancing in the third quarter of 2024. These amounts are primarily offset by the issuance of Term Loan F-2, draws on our Revolving Credit Facility, and AR Securitization of $235 million, $10 million, and $6 million, respectively. During the year ended December 31, 2024, the Company also paid $62 million in dividends and paid $69 million to repurchase shares pursuant to our share repurchase program.

Cash used for financing activities from continuing operations for the year ended December 31, 2023 primarily reflects the payments of $70 million, $36 million, $26 million, and $31 million on our outstanding principal debt balances for the Revolving Credit Facility, AR Securitization, Term Loan F, and Term Loan A, respectively. Additionally, $360 million was paid to bond holders as part of our tender offer. These amounts are primarily offset by the issuance of Term Loan A, draws on our Revolving Credit Facility, and AR Securitization of $300 million, $70 million, and $78 million, respectively. During the year ended December 31, 2023, the Company also paid $57 million in dividends and paid $70 million to repurchase shares pursuant to our share repurchase program.

Contractual obligations for future payments at December 31, 2024 primarily relate to lease commitments, raw material purchase obligations and principal debt payments. Operating and financing leases represent minimum required lease payments during the noncancelable lease term. Most real estate leases also require payment of related operating expenses such as taxes, insurance, utilities, and maintenance, which are not included in our estimated capital lease obligation. Our total estimated finance lease obligations total $2 million in 2025, an average of $2 million from 2025 to 2029 and $7 million thereafter.

Purchase obligations for commercial commitments include inventory obligations to purchase raw materials, including starch, electricity, fuel oil, corrugated boxes, wood and Precipitated Calcium Carbonate (“PCC”). Our total estimated commercial commitments include $305 million in 2025, $168 million in 2026 and average $58 million annually from 2027 to 2029, with $109 million thereafter.

At December 31, 2024, contractual obligations for future payments of debt maturities (including finance lease liabilities disclosed in Note 10 Leases) by calendar year were as follows: 2025 - $22 million; 2026 - $25 million; 2027 - $370 million; 2028 - $25 million; 2029 - $191 million; thereafter - $180 million.

For the year ended December 31, 2024, we have invested approximately $221 million, or 5.9% of net sales in total capital expenditures. Of that amount, we spent approximately $195 million, or 5.2% of net sales, on maintenance, regulatory and reforestation capital expenditures, and approximately $27 million, or 0.7% of net sales, on high-return capital projects. Our annual maintenance, regulatory and reforestation capital expenditures are expected to be in the range of approximately $175 to $190 million per year (before inflation) for the next several years, which we believe will be sufficient to maintain our operations and productivity. In addition, we expect to invest approximately $50 to $70 million in high-return projects in 2025.

The Organization for Economic Co-Operation and Development (“OECD”) has been working on a project to act to prevent what it refers to as base erosion and profit shifting (“BEPS”). Most recently, the OECD, through an association of almost 140 countries known as the “inclusive framework,” has announced a consensus to address, among other things, perceived challenges presented by global digital commerce (“Pillar 1”) and the perceived need for a minimum global effective tax rate of 15% (“Pillar 2”). On December 15, 2022, the European Union formally adopted the Pillar Two Directive, and a majority of EU member states have enacted the directive into domestic law as of December 31, 2023. Other countries are taking similar actions. We have evaluated the developments and do not anticipate any material impact on our financial position, results of operations, or cash flows.

The preparation of financial statements in conformity with U.S. GAAP requires the Company to establish accounting policies and to make estimates that affect both the amounts and timing of the recording of assets, liabilities, revenues and expenses. Some of these estimates require subjective judgments about matters that are inherently uncertain.

Accounting policies whose application may have a significant effect on the reported results of operations and financial position of the Company, and that can require judgments by management that affect their application, include the accounting for impairment or disposal of long-lived assets and goodwill, income taxes and commitments and contingencies.

An impairment of a long-lived asset exists when the asset’s carrying amount exceeds its fair value and is recorded when the carrying amount is not recoverable through undiscounted cash flows from future operations or disposals. A goodwill impairment exists when the carrying amount of goodwill exceeds its fair value. Assessments of possible impairments of long-lived assets and goodwill are made when events or changes in circumstances indicate that the carrying value of the asset may not be recoverable or may, if a business is classified as held for sale, exceed the sales price less costs to dispose. Additionally, evaluation for possible impairment of goodwill is required annually. The amount and timing of any impairment charges based on these assessments may require the estimation of future cash flows or the fair market value of the related assets based on management’s best estimates of certain key factors, including future selling prices and volumes, operating, raw material, energy and freight costs, various other projected operating economic factors and other intended uses of the assets. As these key factors change in future periods, the Company will update its impairment analysis to reflect its latest estimates and projections.

Our policy around goodwill impairment testing permits us to perform a qualitative assessment or a quantitative goodwill impairment test. If a qualitative assessment is performed, an entity is not required to perform the quantitative goodwill impairment test unless the entity determines that, based on that qualitative assessment, it is more likely than not that its fair value is less than its carrying value.

The Company performed its annual testing of goodwill impairment by applying the qualitative assessment to its France reporting unit as of October 1, 2024. For the current year evaluation, the Company assessed various assumptions, events and circumstances that would have affected the estimated fair value of the reporting unit under the qualitative assessment. The results of the qualitative assessment indicated that it is not more likely than not that the fair values of its France reporting unit was less than its carrying value.

The Company also performed its annual testing of goodwill impairment by applying the quantitative goodwill impairment test to its Brazil reporting unit due to the length of time lapsed since the previous quantitative goodwill impairment test. The Company calculated the estimated fair value of the Brazil reporting unit using a probability-weighted approach based on discounted future cash flows, market multiples and transaction multiples. As a result, the Company concluded that the fair value of the Brazil reporting unit was substantially in excess of carrying value and no goodwill impairment charge was recorded.

In addition, the Company considered whether there were any events or circumstances outside of the annual evaluation that would reduce the fair value of its reporting units below their carrying amounts and necessitate a goodwill impairment evaluation. In consideration of all relevant factors, there were no indicators that would require goodwill impairment subsequent to October 1, 2024.

No goodwill impairment charges were recorded in 2024, 2023 or 2022.

We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, we determine deferred tax balances on the basis of the differences between the financial statement and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax balances is recognized in income in the period that includes the enactment date.

We recognize deferred tax assets to the extent that we believe that these assets are more likely than not to be realized. Judgment is required in evaluating the need for and magnitude of appropriate valuation allowances against deferred tax assets. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, carryback potential if permitted under the tax law and results of recent operations. If we determine that we would not be able to realize our deferred tax assets in the future in excess of their net recorded amount, we would not benefit the projected losses in our annual effective estimated tax rate and/or make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.

We record uncertain tax positions in accordance with ASC 740. Significant judgment is required in evaluating the need for and magnitude of appropriate uncertain tax positions. We estimate uncertain tax positions on the basis of a two-step process in which (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority.

While we believe that these judgments and estimates are appropriate and reasonable under the circumstances, actual resolution of these matters may differ from recorded estimates and amounts.

Accruals for contingent liabilities, including environmental and safety matters, taxes (including VAT), personal injury, product liability, labor and employment, contracts, sales of property and other matters, are recorded when it is probable that a liability has been incurred or an asset impaired and the amount of the loss can be reasonably estimated. Liabilities accrued for value-added tax and other legal matters require judgments regarding projected outcomes and range of loss based on historical litigation and settlement experience and recommendations of legal counsel and, if applicable, other experts. Liabilities for environmental matters require evaluations of relevant environmental regulations and estimates of future remediation alternatives and costs. Claims-based liabilities require review of recent and historical claims data. The Company utilizes its in-house legal and environmental experts to develop estimates and involves third-party specialists as needed to analyze its most complex contingent liabilities.

See Note 3 Recent Accounting Developments in Item 8. Financial Statements and Supplementary Data for a discussion of new accounting pronouncements.

The Company has operations in a number of countries. Its operations in those countries also export to, and compete with, imports from other regions. As such, currency movements can have a number of direct and indirect impacts on the Company’s financial statements. Direct impacts include the translation of international operations’ local currency financial statements into U.S. dollars and the remeasurement impact associated with non-functional currency financial assets and liabilities. Indirect impacts include the change in competitiveness of imports into, and exports out of, the countries in which we operate due to the local currency pricing of products. The currencies that have the most impact on our continuing operations are the Euro and the Brazilian real.

We use financial instruments, including fixed and variable rate debt. We do not use financial instruments for trading purposes. Additionally, various derivative contracts are used to hedge exposures to interest rate and foreign currency risks.

Sylvamo is subject to interest rate risk in connection with the issuance of debt. Our exposure to interest rate risk arises primarily from changes in SOFR. As of December 31, 2024, Sylvamo had floating rate debt of $796 million comprised of Term Loan F, Term Loan F-2, Term Loan A and amounts drawn on the Securitization Program, which is partially offset by $652 million of interest rate swaps. At December 31, 2024, the applicable one-month SOFR rate was 4.36%. Based on the amounts outstanding, a 100-basis point increase in market interest rates would result in a change to annual interest expense, including the impact of the swaps, of approximately $1 million at December 31, 2024. As of December 31, 2023, Sylvamo had floating rate debt of $859 million comprised of Term Loan F, Term Loan A and amounts drawn on the Securitization Program, which is partially offset by $469 million of interest rate swaps. At December 31, 2023, the applicable one-month SOFR rate was 5.36%. Based on the amounts outstanding, a 100-basis point increase in market interest rates would result in a change to annual interest expense of approximately $4 million at December 31, 2023. For more information about our term loans, Revolving Credit Facility, and Securitization Program see Note 14 Long-Term Debt to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.

The Company transacts business in many currencies and is also subject to currency exchange rate risk through investments and businesses owned and operated outside the United States. Our objective in managing the associated foreign currency risks is to minimize the effect of exchange rate fluctuations on our after-tax cash flows. We address these risks on a limited basis by entering into cross-currency interest rate swaps or foreign exchange contracts. At December 31, 2024 and 2023 the net fair value of financial instruments with exposure to foreign currency risk was approximately a $14 million liability and a $6 million asset, respectively. The potential loss in fair value for such financial instruments from a 10% adverse change in quoted foreign currency exchange rates would have been approximately $14 million and $12 million at December 31, 2024 and 2023, respectively.

The information set forth in Part II, Item 7 of this Annual Report on Form 10-K under “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Market Risk” is incorporated by reference into this Item 7A.

The management of Sylvamo Corporation is responsible for the preparation of the consolidated financial statements in this Annual Report on Form 10-K. The consolidated financial statements have been prepared using accounting principles generally accepted in the United States of America considered appropriate in the circumstances to present fairly the Company’s consolidated financial position, results of operations and cash flows on a consistent basis. Management has also prepared the other information in this annual report and is responsible for its accuracy and consistency with the consolidated financial statements.

As can be expected in a complex and dynamic business environment, some financial statement amounts are based on estimates and judgments. Even though estimates and judgments are used, measures have been taken to provide reasonable assurance of the integrity and reliability of the financial information contained in this annual report. We have formed a Disclosure Committee to oversee this process.

The accompanying consolidated financial statements have been audited by the independent registered public accounting firm Deloitte & Touche LLP (PCAOB ID No. 34). During its audits, Deloitte & Touche LLP was given unrestricted access to all financial records and related data, including minutes of all meetings of shareholders and the Board of Directors and all committees of the board. Management believes that all representations made to the independent auditors during their audits were valid and appropriate.

The management of Sylvamo Corporation is also responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Internal control over financial reporting is the process designed by, or under the supervision of, our principal executive officer and principal financial officer, and effected by our Board of Directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes. All internal control systems have inherent limitations, including the possibility of circumvention and overriding of controls, and therefore can provide only reasonable assurance of achieving the designed control objectives. The Company’s internal control system is supported by written policies and procedures, contains self-monitoring mechanisms, and is audited by the internal audit function. Appropriate actions are taken by management to correct deficiencies as they are identified. Our procedures for financial reporting include the active involvement of senior management, our Audit Committee and our staff of highly qualified financial and legal professionals.

The Company has assessed the effectiveness of its internal control over financial reporting as of December 31, 2024. In making this assessment, it used the criteria described in “Internal Control – Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). Based on this assessment, management believes that, as of December 31, 2024, the Company’s internal control over financial reporting was effective.

The Company’s independent registered public accounting firm, Deloitte & Touche LLP, has issued its report on the effectiveness of the Company’s internal control over financial reporting. The report appears on page 51.

Our internal control environment includes an enterprise-wide attitude of integrity and control consciousness that establishes a positive “tone at the top.” This is exemplified by our ethics program that includes principles and policies on ethical business conduct that require employees to maintain the highest ethical and legal standards in the conduct of Sylvamo business, which have been distributed to all employees; a toll-free telephone helpline whereby any employee may anonymously report suspected violations of law or Sylvamo’s policy; and our Global Ethics and Compliance Office. The internal control system further includes careful selection and training of supervisory and management personnel, appropriate delegation of authority and division of responsibility, dissemination of accounting and business policies throughout Sylvamo, and an extensive program of internal audits with management follow-up.

The Board of Directors, assisted by the Audit Committee, monitors the integrity of the Company’s financial statements and financial reporting procedures, the performance of the Company’s internal audit function and independent auditors, and other matters set forth in its charter. The Audit Committee, which consists of independent directors, meets regularly with representatives of management, and with the independent auditors and the internal auditor, with and without management representatives in attendance, to review their activities. The Audit Committee’s Charter takes into account the New York Stock Exchange rules relating to Audit Committees and the SEC rules and regulations promulgated as a result of the Sarbanes-Oxley Act of 2002. The Committee has reviewed and discussed the consolidated financial statements for the year ended December 31, 2024, including critical accounting policies and significant management judgments, with management and the independent auditors. The Committee’s report recommending the inclusion of such financial statements in this Annual Report on Form 10-K will be set forth in our Proxy Statement.

We have audited the accompanying consolidated balance sheets of Sylvamo Corporation (the "Company") as of December 31, 2024 and December 31, 2023, the related consolidated statements of operations, comprehensive income, changes in equity, and cash flows for each of the three years in the period ended December 31, 2024, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and December 31, 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 20, 2025, expressed an unqualified opinion on the Company's internal control over financial reporting.

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the 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.

The Company accounts for uncertain tax positions on the basis of a two-step process in which management (1) determines whether it is more likely than not that the tax position will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. Specialized skill and knowledge and significant judgment is often required to evaluate each uncertain tax position to determine whether the more likely than not recognition threshold has been met and, if met, to determine the largest amount of benefit greater than 50 percent likely of being realized upon settlement with the taxing authorities.

The Brazilian Federal Revenue Service has challenged the deductibility of goodwill amortization generated in a 2007 acquisition by Sylvamo do Brasil Ltda., a wholly-owned subsidiary of the Company. The Company has determined this tax position meets the more likely than not threshold for recognition, and no liability for this uncertain tax position has been recorded as the Company has determined that the transaction underlying these assessments was appropriately evaluated, and that the Company’s tax position will be sustained, based on Brazilian tax law.

We identified the Company’s accounting for this tax position as a critical audit matter because of the complexity of the Brazilian tax laws and regulations, the materiality of the potential tax consequences, the fact that all decisions concerning this matter are to be made by the Company’s former parent, and the need to involve our income tax specialists when performing audit procedures to evaluate the Company’s conclusion that its position will be sustained based on Brazilian tax law.

With the assistance of our income tax specialists, the audit procedures we performed related to the Company’s conclusion that its position will be sustained based on Brazilian tax law included the following, among others:

•We read the correspondence from the Brazilian Federal Revenue Service that challenged the deductibility of goodwill amortization. We read and evaluated management's documentation, including relevant accounting policies and information obtained by management from outside tax specialists, that detailed the basis of the uncertain tax position.

•We tested the reasonableness of management's judgments regarding the future resolution of the uncertain tax position, including an evaluation of the technical merits of the uncertain tax position.

•We evaluated whether management has appropriately considered new information that could significantly change the recognition, measurement or disclosure of the uncertain tax position, including information gathered from inquiries of the Company’s former parent’s management regarding their intent to vigorously defend the tax position.

•We evaluated the reasonableness of management’s estimates by considering how Brazilian tax law, including statutes, regulations and case law, impacted management’s judgments.

•We evaluated the appropriateness and consistency of management's methods and assumptions used in the identification, recognition, measurement, and disclosure of the uncertain tax position.

We have served as the Company's auditor since 2020.

We have audited the internal control over financial reporting of Sylvamo Corporation (the "Company") as of December 31, 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 Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2024, of the Company and our report dated February 20, 2025, expressed an unqualified opinion on those financial statements.

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Report of Management on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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 (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) 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 (3) 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.
