nVent is a leading global provider of electrical connection and protection solutions. We believe our inventive electrical solutions enable safer systems and ensure a more secure world. We connect and protect some of the world's most critical electrical systems to make them safer, more efficient and resilient. We design, manufacture, market, install and service high performance products and solutions that connect and protect mission critical equipment, buildings and essential processes. We have a comprehensive portfolio of bus systems, cable management, control buildings, cooling solutions, both liquid and air, electrical connections, enclosures, equipment protection, power connections and power management solutions, and switchgear systems, and we are recognized globally for quality, reliability and innovation.

Our broad range of products and solutions support infrastructure, industrial, commercial and residential, and energy applications around the world. Our solutions help our customers improve energy efficiency, ensure resiliency and protection, increase customer productivity, enhance safety and contribute to more sustainable operations.

At nVent, we operate across two segments: Systems Protection and Electrical Connections. In 2025, we renamed our Enclosures segment to Systems Protection and our Electrical & Fastening Solutions segment to Electrical Connections.

Our portfolio of premier, industry-leading brands, some of which have a history spanning over 100 years, includes nVent CADDY, ERICO, HOFFMAN, ILSCO, SCHROFF and TRACHTE.

Unless the context otherwise indicates, references herein to "nVent," the "Company," and such words as "we," "us," and "our" include nVent Electric plc and its consolidated subsidiaries. Our principal office is in London, United Kingdom and our management office in the United States ("U.S.") is in Minneapolis, Minnesota. The Company was incorporated in Ireland on May 30, 2017. Although our jurisdiction of organization is Ireland, we manage our affairs so that we are centrally managed and controlled in the United Kingdom (the "U.K.") and have our tax residency in the U.K.

On April 30, 2018, Pentair plc ("Pentair") completed the separation of its Water business and its Electrical business into two independent, publicly-traded companies (the "separation"). To effect the separation, Pentair distributed to its shareholders one ordinary share of nVent for every ordinary share of Pentair held as of the record date of April 17, 2018. As a result of the distribution, nVent became an independent publicly-traded company and began trading under the symbol "NVT" on the New York Stock Exchange on May 1, 2018.

Our roots within Pentair trace back to the acquisition of Federal-Hoffman Corporation in 1988, which included the nVent HOFFMAN Systems Protection brand. From that starting point, we have grown both organically and via acquisitions. Our Systems Protection business first applied lean principles within the organization in the 1990s, leveraging its culture of customer service and operational excellence. In 2015, Pentair acquired ERICO Global Company, a leading global manufacturer of superior engineered electrical and fastening products, which operates as our Electrical Connections business, broadening our product offering and enabling us to provide additional global solutions to our combined customers.

In 2023, as part of our Electrical Connections reporting segment, we completed the acquisition of ECM Investors, LLC, the parent of ECM Industries, LLC ("ECM Industries"), for approximately $1.1 billion in cash. ECM Industries is a leading provider of high-value electrical connectors, tools and test instruments and cable management.

In 2024, we completed the acquisition of Trachte, LLC ("Trachte") as part of our Systems Protection reporting segment, for approximately $0.7 billion in cash. Trachte is a leading manufacturer of engineered control building solutions designed to protect critical infrastructure assets.

In 2025, we completed the sale of the Thermal Management business to BCP VI Summit Holdings LP (as assignee of BCP Acquisitions LLC), an affiliate of funds managed by Brookfield Asset Management, for $1.6 billion in net cash proceeds, subject to certain customary purchase price adjustments. The Thermal Management business was previously disclosed as a stand-alone reporting segment, and is now presented as a discontinued operations in our Consolidated Financial Statements for all periods presented.

In 2025, we completed the acquisition of the enclosures, switchgear and bus systems businesses of Avail Infrastructure Solutions (the "Electrical Products Group") for approximately $1.0 billion in cash. The Electrical Products Group is a leading provider of infrastructure solutions, designed to help ensure safe and reliable electrical operations primarily in the infrastructure vertical, including power utilities and data centers.

We are “One nVent”, with a unified focus on commercial excellence, digital transformation, scaled and integrated technology, and global presence and capabilities. As we continue scaling our capabilities under our umbrella brand of nVent, we expect to expand our products and solutions and to continue to differentiate our company by creating solutions that solve problems for our customers.

Our Spark management system defines how we operate. The five elements of Spark are People, Growth, Lean, Digital and Velocity. Together, they provide the mindset and operating system to propel the success of our company. Spark supports the high performance culture we are building at nVent.

•People are at the core of Spark, positively impacting our business and growing their careers.

•Growth is the foundation of Spark, driving shareholder, customer and employee value.

•Lean is the relentless pursuit of eliminating waste and increasing velocity.

•Digital transforms our products and how we do business, improving both customer and employee experiences.

•Velocity is increasing speed in all we do for each other and our customers.

Our Systems Protection business provides innovative solutions to help protect electronics, systems and data in mission critical applications, including data centers, that improve resiliency and energy efficiency.

We are an enclosures and liquid cooling leader in the U.S. and globally. We believe that trends like electrification, sustainability and digitalization, including increased use of artificial intelligence, are helping to drive the need for our products. Our standard and custom protective enclosures, cooling solutions, both liquid and air, control buildings, switchgear systems and power distribution solutions help protect operating environments for mission critical applications.

Our solutions help make systems more resilient, helping avoid downtime. We sell globally but serve locally with regional manufacturing and supply chains. Our solutions are primarily used by hyperscalers, utilities, original equipment manufacturers, panel builders and contractors.

Our Systems Protection brands include nVent HOFFMAN, SCHROFF and TRACHTE.

Our Electrical Connections business provides innovative solutions that connect power and data infrastructure. Our offerings enhance end-user safety, reduce installation time and provide resiliency for critical systems.

We are a leading global provider known for our application expertise and innovative labor saving solutions. Our bus systems, cable management, electrical connections and solutions, and power connections help make electrical systems safe, efficient and resilient.

Our products and solutions are primarily used by contractors, electrical utilities, electricians and panel builders.

Our Electrical Connections brands include nVent CADDY, ERICO and ILSCO.

The markets for our products and services are geographically diverse and highly competitive. We compete against large and well-established national and global companies, as well as regional and local companies and lower-cost manufacturers. Some of our competitors, in particular smaller companies, attempt to compete based primarily on price, localized expertise and local relationships. The number and size of competitors vary considerably depending on the product line.

Our success depends on a variety of factors, including technical expertise, reputation for quality and reliability, timeliness of delivery, new product innovation, previous installation history, contractual terms and price. As many of our products sell through electrical distributors, retail, contractors and original equipment manufacturers, our success also depends on building and partnering with a strong channel and distribution network.

We generally experience increased demand for Electrical Connections products during the spring and summer months in the Northern Hemisphere.

A majority of our revenues result from orders received and products delivered in the same month and products generally ship within 90 days of the date on which a customer places an order. However, a growing portion of our backlog, particularly in the infrastructure vertical, has a longer design and manufacturing process, and can take more than one year depending on the size and type of order. We record as part of our backlog all orders from external customers, which represent firm commitments, and are supported by a purchase order or other legitimate contract. The increase in backlog from 2024 to 2025 was primarily the result of the acquisition of the Electrical Products Group and the growth of our data centers business. We expect the majority of our backlog at December 31, 2025 will be shipped in 2026.

The principal materials we use in manufacturing our products are mild steel, stainless steel, electronic components, copper, aluminum and paint (powder and liquid). In addition to the purchase of raw materials, we purchase some finished goods for distribution through our sales channels.

We purchase the materials we use in various manufacturing processes on the open market and the majority is available through multiple sources which are in adequate supply. We have certain long-term commitments, principally price commitments, for the purchase of various component parts and raw materials and believe that it is unlikely that any of these agreements would be terminated prematurely. Alternate sources of supply at competitive prices are available for most materials for which long-term commitments exist and we believe that the termination of any of these commitments would not have a material adverse effect on our financial position, results of operations or cash flows.

See Item 1A, Risk Factors, in this Form 10-K for additional information on risks related to supply chain and inflation.

Patents, non-compete agreements, proprietary technologies, customer relationships, trademarks, trade names and brand names are important to our business. However, we do not regard our business as being materially dependent upon any single patent, non-compete agreement, proprietary technology, customer relationship, trademark, trade name or brand name.

Patents, patent applications and license agreements will expire or terminate over time by operation of law, in accordance with their terms or otherwise. We do not expect the termination of patents, patent applications or license agreements to have a material adverse effect on our financial position, results of operations or cash flows.

We insure certain general and product liability, property, workers' compensation and automobile liability risks through our regulated wholly-owned captive insurance subsidiary, Tonka Bay Insurance Company ("Tonka Bay"). Reserves for policy claims are established based on actuarial projections of ultimate losses. Accruals are established with respect to liabilities insured by third parties, such as liabilities arising from acquired businesses, pre-Tonka Bay liabilities and those of certain non-U.S. operations.

Matters pertaining to Tonka Bay are discussed in ITEM 3, included in this Form 10-K.

As of December 31, 2025, we employed approximately 12,000 people worldwide, of which approximately 48% are located in the U.S. Outside the U.S., we have employees in certain countries that are represented by an employee representative organization, such as a union, works council or employee association.

Guided by our Win Right values, we are committed to creating a workplace culture where everyone is included and respected. We believe that the unique contributions of individuals with varying backgrounds and experiences will benefit our businesses. Our Code of Conduct outlines our commitment to equal opportunity and fair treatment for all.

We currently have nine Employee Resource Groups (“ERGs”) designed to create opportunities for development while assisting in meeting business objectives. All ERGs are employee-led and employee-driven and open to all nVent employees. They provide a support system to foster awareness, inclusion and respect.

In 2025, our ERG membership grew to over 2,000 members.

We strive to offer our employees across the world comprehensive benefit programs that reflect the market practices in their country of employment. We participate in and review remuneration surveys from leading, independent consultants for all of our countries so that we have the information to set competitive wages and salaries.

We are dedicated to providing equitable compensation as a commitment to our people. By focusing on equitable pay, we enhance our ability to grow, retain and motivate diverse employees on our team. We believe diverse teams drive innovation, connection and growth for our employees.

As part of this commitment to our people, we conduct pay parity reviews of our compensation. The goal of these reviews is to ensure internal pay alignment and equitable treatment for employees, as well as providing competitive and performance-based pay.

We believe it is important to hear from our employees to learn about what we are doing well and where we can become stronger through regular employee engagement surveys. Since 2018, we continue to have above benchmark participation in our employee engagement surveys, and our employee engagement score has increased 7 points since our first survey.

All of our people leaders were required to share survey results with their teams and develop action plans to address specific areas of improvement. In addition, throughout 2025, we conducted two pulse surveys and one full engagement survey, which included questions focused on our Inclusion Index and employee satisfaction. Leaders reviewed the results with their teams and created focused action plans based on the results. As part of our annual goal planning process, all of our people leaders were assigned a people leader goal focused on engaging and developing their employees. Action items in the people leader goal included: completing all performance processes including goal setting, mid-year, and annual reviews; creating an action plan from the 2025 employee engagement survey results; focusing on our safety-first approach; ensuring new employees complete nVent culture training; driving diverse slates within the interviewing process; and helping to ensure the completion of all ethics and compliance trainings.

Career development was identified as an area of focus following our 2025 engagement survey, and we continued our efforts to develop our people throughout 2025. We focus on developing our employees through Continuous Conversation development discussions between employees and people leaders. We provide development opportunities for employees to learn through interactions with other leaders in our enterprise-wide and senior level mentorship programs. We also offer a rotational program for early career hires to grow in their careers. We continue to grow our employees in their capabilities to lead through change and transition. Lastly, we are continuing to digitalize and standardize our performance process for our global hourly production employees so that our leaders continue to regularly engage with their employees to discuss performance, development and career aspirations.

In 2025, our Code of Business Conduct and Ethics training was offered in 12 different languages to employees in 35 countries. 100% of professional employees completed the training, including topics such as responsible use of social media, the importance of reporting ethical concerns, identifying and mitigating bribery and corruption risks and cybersecurity, data privacy, and acceptable use of artificial intelligence. In 2025, we also trained 100% of our offline, factory team members globally on our Code of Conduct.

We offer a number of resources to report concerns, including a confidential helpline, website, text messaging support and dedicated email inbox. We prohibit any form of retaliation against anyone reporting in good faith and take all reported concerns seriously.

We are committed to maintaining a healthy and safe work environment and preventing workplace injuries. We use a safety model based on three pillars: employee engagement, controlled hazards and management commitment.

We have strong participation in safety committees and behavior-based safety activities, and we empower employees to actively identify areas for improvement and solutions. We actively encourage employees to report all incidents so that we can identify opportunities to improve before significant events occur.

We have established a detailed list of safety standards, hold sites accountable to those standards and continuously look for ways to improve and comply with relevant regulations and expectations.

Our managers invest in continuous improvement, lead by example, communicate openly, lead safety initiatives, build trust within teams and consistently model the right safety behavior to create an environment where employee safety is prioritized.

We make available free of charge (other than an investor's own Internet access charges) through our Internet website (http://www.nvent.com) our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and if applicable, amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act as soon as reasonably practicable after we electronically file such material with, or furnish it to, the Securities and Exchange Commission ("SEC"). Reports of beneficial ownership filed by our directors and executive officers pursuant to Section 16(a) of the Exchange Act are also available on our website. We are not including the information contained on our website as part of, or incorporating it by reference into, this Annual Report on Form 10-K.

You should carefully consider all of the information in this document and the following risk factors before making an investment decision regarding our securities. Any of the following risks could materially and adversely affect our business, financial condition, results of operations, cash flows and the actual outcome of matters as to which forward-looking statements are made in this document.

We compete in various geographic regions and product markets around the world. Among these, the most significant are global infrastructure, industrial, and commercial and residential markets. We expect to experience fluctuations in revenues and results of operations due to economic and business cycles. Important factors for our business and the businesses of our customers include the overall strength of the global economy and our customers’ confidence in the economy, industrial and governmental capital spending, the strength of infrastructure and commercial and residential markets, unemployment rates, availability of commercial financing, interest rates, inflation rates, and energy and commodity prices. Recessions, economic downturns, inflation, slowing economic growth and social and political instability in the industries and/or markets where we compete could negatively affect our revenues and financial performance in future periods, result in future restructuring charges, and adversely impact our ability to grow or sustain our business. Macroeconomic and political instability caused by global supply chain disruptions, inflation and the strength of the U.S. dollar could adversely impact our results of operations. In addition, military conflicts and their impact on economies may adversely impact our results of operations. The businesses of many of our industrial customers are to varying degrees cyclical and have experienced periodic downturns. While we attempt to minimize our exposure to economic or market fluctuations by serving a balanced mix of end markets and geographic regions, any of the above factors, individually or in the aggregate, or a significant or sustained downturn in a specific end market or geographic region could reduce demand for our products and services, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

The markets for our products and services are geographically diverse and highly competitive. We compete against large and well-established national and global companies, as well as regional and local companies and lower-cost manufacturers. Competition may also result from new entrants into the markets we serve offering products and/or services that compete with ours. We compete based on technical expertise, reputation for quality and reliability, timeliness of delivery, previous installation history, contractual terms and price. Some of our competitors attempt to compete based primarily on price, localized expertise and local relationships. In addition, economic downturns could adversely affect pricing as market participants compete more aggressively on price. If we are unable to continue to differentiate our products, services and solutions, or if our pricing is adversely impacted or we incur additional costs to remain competitive, it could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We operate in global markets that are characterized by customer demand that is often global in scope but localized in delivery. We compete with thousands of smaller regional and local companies that may be positioned to offer products produced at lower cost than ours, or to capitalize on highly localized relationships. Also, in several emerging markets potential customers prefer local suppliers, in some cases because of existing relationships and in other cases because of local legal restrictions or incentives that favor local businesses. In addition, we need to be flexible to adapt our products to ever changing customer preferences, including those relating to regulatory, sustainability and social responsibility matters.

Accordingly, our future success depends upon a number of factors, including our ability to adapt our products, services, organization, workforce and sales strategies to fit localities throughout the world, particularly in high-growth emerging markets; identify emerging technological and other trends in our target end markets; and develop or acquire competitive products and services and bring them to market quickly and cost-effectively. The failure to effectively adapt our products or services could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our business strategy includes acquiring businesses and making investments that complement our existing business. We expect to analyze and evaluate the acquisition of strategic businesses or product lines with the potential to extend or strengthen our industry position or enhance our existing set of product and service offerings. We may not be able to identify suitable acquisition candidates, obtain financing or have sufficient cash necessary for acquisitions or successfully complete acquisitions in the future. Acquisitions and investments may involve significant cash expenditures, debt incurrences, equity issuances, operating losses and expenses. Acquisitions involve numerous other risks, including:

•diversion of management time and attention from daily operations;

•difficulties integrating acquired businesses, technologies and personnel into our business;

•difficulties in obtaining and verifying the financial statements and other business information of acquired businesses;

•inability to obtain required regulatory approvals;

•potential loss of key employees, key contractual relationships or key customers of acquired companies or of ours;

•assumption of the liabilities and exposure to unforeseen liabilities of acquired companies; and

•dilution of interests of holders of nVent ordinary shares through the issuance of equity securities or equity-linked securities.

It may be difficult for us to complete transactions quickly and to integrate acquired operations efficiently into our business operations or realize expected financial benefits of acquired businesses. Any acquisitions or investments may not be successful and may ultimately result in impairment charges and have a material adverse effect on our business, financial condition, results of operations and cash flows.

During 2025 and 2024, we continued execution of certain business restructuring initiatives aimed at reducing our fixed cost structure and realigning our business. In order to align our resources with our growth strategies, operate more efficiently and control costs, we may periodically announce future restructuring plans, which may include workforce reductions, global plant closures and consolidations, asset impairments and other cost reduction initiatives. As these plans and actions are complex, we may not be able to achieve the operating efficiencies to reduce costs or realize benefits that were anticipated in connection with these initiatives. If we are unable to execute these initiatives as planned, we may not realize all or any of the anticipated benefits, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

In 2025 and 2024, we experienced inflationary increases of raw materials, logistics and labor costs. We strive for productivity improvements and implement increases in selling prices to help mitigate cost increases in raw materials, freight, energy, wage and other costs such as pension, health care and insurance. We continue to implement operational initiatives in order to mitigate the impact of this inflation and continuously reduce our costs. However, these actions may not be successful in managing our costs or increasing our productivity. Continued cost inflation or failure of our initiatives to increase prices, generate cost savings or improve productivity could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our business is subject to risks associated with global manufacturing and sourcing. We use a variety of raw materials in the production of our products including steel, copper, aluminum and paints. We also purchase certain electronic components, electrical and packaging materials from a number of suppliers. Although we regularly monitor the financial health and operations of companies in our supply chain, and use alternative suppliers when necessary and available, supply chain constraints could cause a disruption in our ability to obtain raw materials or components required to manufacture our products and adversely affect our operations. Significant shortages in the availability of these materials or price increases could increase our operating costs and adversely impact the competitive positions of our products. We rely on materials, components and finished goods that are sourced from or manufactured in locations outside the U.S., including Mexico, China and other countries, and these countries may experience political or trade instability, which could disrupt our supply of products or materials.

We rely on our suppliers to produce high quality materials, components and finished goods according to our specifications. Although we have quality control procedures in place, there is a risk that products may not meet our specifications which could impact our ability to ship quality products to our customers on a timely basis.

Our backlog is comprised of the portion of firm signed purchase orders or other written contractual commitments received from customers that we have not recognized as revenue. Backlog may increase or decrease based on the addition of large multi-year projects and their subsequent completion. Backlog may also be favorably or unfavorably affected by foreign currency rate fluctuations. The dollar amount of backlog as of December 31, 2025 was $2.3 billion. The timing of our recognition of revenue out of our backlog is subject to a variety of factors that may cause delays, many of which, including fluctuations in our customers’ delivery schedules, are beyond our control. Such delays may lead to significant fluctuations in results of operations from quarter to quarter, making it difficult to predict our financial performance on a quarterly basis. Further, while we have historically experienced few order cancellations and the amount of order cancellations has not been material compared to our total contract volume, if we were to experience a significant amount of cancellations of or reductions in purchase orders, it would reduce our backlog and, consequently, our future sales and could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our future revenue and overall results of operations require us to successfully bid on new contracts and, in particular, contracts for large greenfield projects, which are frequently subject to competitive bidding processes. Our revenue from major projects depends in part on the level of capital expenditures in some of our principal end markets, particularly in the infrastructure vertical, which includes our data centers and power utilities businesses. The number of such projects we win in any year fluctuates, and is dependent upon the number of projects available and our ability to bid successfully for such projects. Contract proposals and negotiations are complex and frequently involve a lengthy bidding and selection process, which is affected by a number of factors, such as competitive position, market conditions, financing arrangements and required governmental approvals. If negative market conditions arise, or if we fail to secure adequate financial arrangements or required governmental approvals, we may not be able to pursue particular projects or win new contracts, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Sales outside of the U.S. for the year ended December 31, 2025 accounted for approximately 24% of our net sales. Further, our business obtains some products, components and raw materials from non-U.S. suppliers. Accordingly, our business is subject to the political, regulatory, economic and other risks that are inherent in operating in numerous countries. These risks include:

•changes in diplomatic and trade relationships, as well as the imposition of tariffs, sanctions, duties, exchange controls, currency restrictions or other trade restrictions;

•changes in general economic and political conditions in countries where we operate, particularly in emerging markets;

•relatively more severe economic conditions in some international markets than in the U.S.;

•the difficulty of enforcing agreements and collecting receivables through non-U.S. legal systems;

•the difficulty of communicating and monitoring standards and directives across our global facilities;

•the difficulty of ensuring that our products, services and supply chains meet ever-changing regional regulations and requirements;

•trade protection measures and import or export licensing requirements and restrictions;

•the possibility of terrorist action or military conflict affecting us, our operations, supply chains or end-markets or economies generally;

•the threat of nationalization and expropriation;

•difficulty in staffing and managing widespread operations in non-U.S. labor markets;

•changes in tax treaties, laws or rulings that could have a material adverse impact on our effective tax rate;

•limitations on repatriation of earnings;

•the difficulty of protecting intellectual property in non-U.S. countries; and

•changes in and required compliance with a variety of non-U.S. laws and regulations.

Our success depends in part on our ability to anticipate and effectively manage these and other risks. We cannot assure you that these and other factors will not have a material adverse effect on our international operations or on our business as a whole.

Our net sales to our largest customer represented approximately 11% of our consolidated net sales in 2025. While we do not have any other customers that accounted for more than 10% of our consolidated net sales in 2025, we have other customers that are key to the success of our business. Our concentration of sales to a number of larger customers makes our relationship with each of these customers important to our business. Our success is dependent on retaining these customers, which requires us to successfully manage relationships and anticipate the needs of our customers in the channels in which we sell our products. Our customers also may be impacted by economic conditions in the industries of those customers, which could result in reduced demand for or a delay in purchases of our products. In addition, our customers may cancel orders for purchases of our products or may not order products at rates consistent with past order levels, or we may not be able to timely deliver products to our largest customers due to supply chain interruptions or otherwise. We cannot provide assurance that we will be able to retain our largest customers. In addition, some of our customers may shift their purchases to our competitors in the future. The loss of one or more of our largest customers, any material cancellation, reduction, or delay in purchases by or delivery of products to these customers, or our inability to successfully develop relationships with additional customers could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We often rely on third party subcontractors as well as third party suppliers and manufacturers to complete projects. To the extent that we cannot engage subcontractors or acquire supplies or materials from third parties for these projects, our ability to complete a project in a timely fashion or at a profit may be impaired. If the amount we are required to pay for these goods and services exceeds the amount we have estimated in bidding for fixed-price contracts, we could experience losses on these contracts. In addition, if a subcontractor, supplier or manufacturer is unable to deliver its services or materials according to the negotiated contract terms for any reason, including the deterioration of its financial condition or over-commitment of its resources, we may be required to purchase the services or materials from another source at a higher price. This may reduce the profit to be realized or result in a loss on a project for which the services or materials were needed.

Patents, non-compete agreements, proprietary technologies, customer relationships, trademarks, trade names and brand names are important to our business. Intellectual property protection, however, may not preclude competitors from developing products similar to ours or from challenging our names or products. Our pending patent applications, and our pending copyright and trademark registration applications, may not be allowed or competitors may challenge the validity or scope of our patents, copyrights or trademarks. In addition, our patents, copyrights, trademarks and other intellectual property rights may not provide us a significant competitive advantage. Furthermore, participants in our markets may use challenges to intellectual property as a means to compete. Patent and trademark challenges increase our costs to develop, engineer and market our products. We may need to spend significant resources monitoring our intellectual property rights and we may or may not be able to detect infringement by third parties. If we fail to successfully enforce our intellectual property rights or register new patents, our competitive position could suffer, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We test goodwill and other indefinite-lived intangible assets for impairment on at least an annual basis, and more frequently if circumstances warrant, by comparing the estimated fair value of our reporting unit to its respective carrying values on its balance sheets. As of December 31, 2025, our goodwill and intangible assets were $4.6 billion and represented 66% of our total assets. Changes in economic and operating conditions impacting the assumptions used in our impairment tests could result in future goodwill and intangible asset impairment expense.

As a result of changes to U.S. and foreign government administrative policy, there may be changes to existing trade agreements, greater restrictions on free trade generally, the imposition of or significant increases in tariffs on goods imported into the U.S. particularly tariffs on steel, aluminum and copper and products manufactured in China, Canada and Mexico, and adverse responses by foreign governments to U.S. trade policies, among other possible changes. Beginning in the second quarter of 2025, new tariffs were announced on imports to the U.S. (“U.S. Tariffs”), including additional tariffs on imports from China, Mexico and the European Union (“EU”), among others. In response, several countries have imposed, or threatened to impose, reciprocal tariffs on imports from the U.S. and other retaliatory measures. Various modifications to the U.S. Tariffs have been announced and further changes could be made in the future.

The ultimate impact of such changes remains uncertain and will depend on several factors, including whether additional or incremental U.S. Tariffs or other measures are announced or imposed, to what extent other countries implement tariffs or other retaliatory measures in response, and the overall magnitude and duration of these measures. Additionally, the U.S. government has announced enhanced focus on customs enforcement, including through the creation of a Trade Fraud Task Force, a cross-agency initiative of the U.S. Departments of Justice and Homeland Security to address trade fraud, tariff evasion, and customs violations. This heightened enforcement paradigm, along with the ongoing litigation regarding tariffs imposed under the International Emergency Economic Powers Act (IEEPA) that was recently heard by the U.S. Supreme Court, have created additional uncertainty as to the scale and short and long-term effect these tariffs will have. A trade war, other governmental action related to tariffs or trade agreements, changes in U.S. social, political, regulatory and economic conditions or in laws and policies governing foreign trade, manufacturing, development and investment in the territories and countries where we currently purchase, manufacture and sell products, and any resulting negative sentiments towards the U.S. as a result of such changes, could have a material adverse effect on our business, financial condition, results of operations and cash flows.

The U.S. Foreign Corrupt Practices Act and similar anti-corruption laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments to government officials or other persons for the purpose of obtaining or retaining business. We operate in many parts of the world that are recognized as having governmental and commercial corruption and in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices. Because many of our customers and end users are involved in infrastructure construction, they are often subject to increased scrutiny by regulators.

Further, our global operations require importing and exporting goods and technology across international borders on a regular basis. Certain of the products we manufacture are “dual use” products, which are products that may have both civil and military applications, or may otherwise be involved in weapons proliferation, and are often subject to more stringent export controls. From time to time, we may obtain or receive information alleging improper activity in connection with imports or exports. Our policies mandate strict compliance with applicable laws and regulations, including those pertaining to anti-corruption, anti-bribery and trade. However, even when we are in strict compliance with law and our policies, we may suffer reputational damage if certain of our products are sold through various intermediaries to entities operating in sanctioned countries. We cannot assure that our internal control policies and procedures will always protect us from reckless or criminal acts committed by our employees or third-party intermediaries. In the event that we believe or have reason to believe that our employees or agents have or may have violated applicable laws, we may be required to investigate or have outside counsel investigate the relevant facts and circumstances, which can be expensive and require significant time and attention from senior management. Violations of these laws may require self-disclosure to governmental agencies and result in criminal or civil sanctions, which could disrupt our business, cause denial of import or export privileges, and result in a material adverse effect on our reputation, business, financial condition, results of operations and cash flows.

We are subject to U.S. federal, state, local and non-U.S. laws and regulations governing our environmental practices, public and worker health and safety, and the indoor and outdoor environment. Compliance with these environmental, health and safety regulations could require us to satisfy environmental liabilities, increase the cost of manufacturing our products or otherwise have a material adverse effect on our business, financial condition, results of operations and cash flows. Any violations of these laws by us could cause us to incur unanticipated liabilities. We are also required to comply with various environmental laws and maintain permits, some of which are subject to renewal from time to time, for many of our businesses and we could suffer if we are unable to renew existing permits or to obtain any additional permits that we may require. Compliance with environmental requirements also could require significant operating or capital expenditures or result in significant operational restrictions. We cannot assure you that we have been or will be at all times in compliance with environmental and health and safety laws. If we violate these laws, we could be fined, criminally charged or otherwise sanctioned by regulators.

We have been named as defendant, target or a potentially responsible party ("PRP") in a number of environmental cleanups relating to our current or former businesses. We may be named as a PRP at other sites in the future for existing businesses, as well as both divested and acquired businesses. In addition to clean-up actions brought by governmental authorities, private parties could bring personal injury or other claims due to the presence of, or exposure to, hazardous substances. Certain environmental laws impose liability on current or previous owners or operators of real property for the cost of removal or remediation of hazardous substances at their properties or at properties at which they have disposed of hazardous substances. The cost of clean-up and other environmental liabilities can be difficult to accurately predict. In addition, environmental requirements change and tend to become more stringent over time. Our eventual environmental clean-up costs and liabilities could exceed the amount of our current reserves.

From time to time, we receive notices from third parties alleging intellectual property infringement. Any dispute or litigation involving intellectual property could be costly and time-consuming due to the complexity and the uncertainty of intellectual property litigation. Our intellectual property portfolio may not be useful in asserting a counterclaim, or negotiating a license, in response to a claim of infringement or misappropriation. In addition, as a result of such claims, we may lose our rights to utilize critical technology, may be required to pay substantial damages or license fees with respect to the infringed rights or may be required to redesign our products at a substantial cost, any of which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Growing concerns over climate change have resulted in, and may continue to result in, new laws, regulations and accords intended to reduce or limit emissions of certain greenhouse gases. Existing and new laws, regulations and accords relating to emissions of certain greenhouse gases may be difficult and costly to comply with, may adversely impact certain aspects of our operations (including but not limited to the manufacture and distribution of our products), may adversely impact certain industries in which we operate, may result in increased energy, input, compliance and other costs, and may decrease demand for certain of our products. Because it is uncertain what laws will be enacted, we cannot predict the potential impact of such laws on our future financial condition, results of operations and cash flows.

Further, concern over climate change has led to legislative and regulatory initiatives across various jurisdictions in which we operate related to disclosures and reporting, including for example the European Sustainability Reporting Standards and the Corporate Sustainability Reporting Directive. Proposals that would impose mandatory disclosure requirements on sustainability matters and greenhouse gas emissions continue to be considered by policy makers and regulators. We cannot predict what climate change related legislation or regulations will be enacted in the future or how existing or future laws or regulations will be administered or interpreted, or if and to what extent existing or future laws or regulations may be subsequently rolled back. Compliance may significantly increase compliance burdens and associated regulatory costs and complexity, and the failure to comply with such legislation and regulations could result in fines to us, and could affect our business, financial condition, results of operations and cash flows.

We may make public statements about various sustainability-related matters and initiatives from time to time, including on our website, in our press releases, in our sustainability report, and in other communications. Addressing stakeholder expectations and regulatory requirements relating to sustainability matters requires an investment of time, money and other resources, any or all of which may increase our cost of doing business. As investor and other stakeholder expectations relating to sustainability matters change and evolve over time, any failure or perceived failure by us to adequately address those expectations may damage our reputation , which could adversely impact the perception of our brands and our products and services by current and potential investors and customers, which could in turn adversely impact our business, results of operations or financial condition.

We rely upon information technology systems and networks in connection with a variety of business activities, some of which are managed by third parties. As our business increasingly interfaces with employees, customers, distributors and suppliers using information technology systems and networks, we are subject to an increased risk to the secure operation of these systems and networks. Our evolution into connected products subjects us to increased cyber and technology risks. The secure operation of these information technology systems and networks is critical to our business operations and strategy.

Cybersecurity threats from user error to attacks designed to gain unauthorized access to our systems, networks and data are increasing in frequency and sophistication, including the risk that threat actors will leverage emerging technology, such as artificial intelligence, to exploit vulnerabilities. These threats pose a risk to the security of our systems and networks and the confidentiality, availability and integrity of the data we process and maintain and pose a risk of theft to our assets. The risk of cybersecurity attacks may increase as artificial intelligence capabilities improve and are increasingly used to identify vulnerabilities and construct increasingly sophisticated cybersecurity attacks, with the possibility of additional vulnerabilities being introduced through our own use of artificial intelligence and its use by our stakeholders, including vendors and customers. Establishing systems and processes to address these threats and changes in legal requirements relating to data collection and storage may increase our costs. Previous cybersecurity incidents have not materially affected us, including our business strategy, results of operations or financial condition. There can be no assurance of similar results in the future. Should future attacks succeed, it could expose us and our employees, customers, distributors and suppliers to the theft of assets, misuse of information or systems, the compromising of confidential information, manipulation and destruction of data, product failures, production downtimes and operations disruptions. The occurrence of any of these events could have a material adverse effect on our reputation, business, financial condition, results of operations and cash flows. In addition, such cybersecurity incidents could result in litigation, regulatory action and potential liability and the costs and operational consequences of implementing further cybersecurity measures.

We collect and store data that is sensitive to us and our employees, customers, distributors and suppliers. A variety of state, national, foreign and international laws and regulations apply to the collection, use, retention, protection, security, disclosure, transfer and other processing of personal and other data. Many foreign data privacy regulations, including the General Data Protection Regulation (the “GDPR”) in the EU and the U.K., are more stringent than federal regulations in the United States. Within the United States, many states are considering adopting, or have already adopted privacy regulations, including, for example, the California Consumer Privacy Act. These laws and regulations are rapidly evolving and changing, and could have an adverse effect on our operations. Companies’ obligations and requirements under these laws and regulations are subject to uncertainty in how they may be interpreted by courts and governmental authorities. The costs of compliance with, and the other burdens imposed by, these and other laws or regulatory actions may increase our operational costs, and/or result in interruptions or delays in the availability of systems. In the case of non-compliance with these laws, including the GDPR, regulators have the authority to levy significant fines. In addition, if there is a breach of privacy, we may be required to make notifications under data privacy laws or regulations, or could become subject to litigation. The occurrence of any of these events could have a material adverse effect on our reputation, business, financial condition, results of operations and cash flows.

We may use artificial intelligence in our business operations. Challenges associated with developing, deploying and governing such technologies could adversely affect our business, reputation and competitive position. The development and use of artificial intelligence involve risks, including the potential for inaccurate, incomplete or biased outputs, that could lead to errors in our decision-making and adversely impact business operations. In addition, employee use of artificial intelligence tools could result in the inadvertent disclosure of confidential or proprietary information to third parties, the misuse of our intellectual property or claims that we have violated third party intellectual property rights.

The rapid evolution of artificial intelligence technologies, together with emerging and potentially divergent governmental regulations and industry standards, may require ongoing investment in governance, monitoring, data security, training and compliance. Failure to appropriately develop, manage, secure and oversee our artificial intelligence activities could expose us to legal liability, operational disruptions, reputational harm and other adverse effects on our business and results of operations.

We are currently, and may in the future become, subject to litigation and other claims. We have been made parties to a number of actions filed or have been given notice of potential claims relating to the conduct of our business, including those pertaining to commercial disputes, product liability, asbestos, environmental, safety and health, patent infringement and employment matters. The outcome of such legal proceedings cannot be predicted with certainty and some may be disposed of unfavorably to us. Our business exposes us to potential litigation, such as product liability claims relating to the design, manufacture and sale of our products. While we currently maintain what we believe to be suitable product liability insurance, we may not be able to maintain this insurance on acceptable terms and this insurance may not provide adequate protection against potential or previously existing liabilities. In addition, we self-insure a portion of product liability claims. Successful claims against us for significant amounts could have a material adverse effect on our reputation, business, financial condition, results of operations and cash flows.

As of December 31, 2025, we had $1.6 billion of total debt on a consolidated basis. We and our subsidiaries may incur additional indebtedness in the future, subject to limitations in our debt agreements. This increase and any future increases in our level of indebtedness will have several important effects on our future operations, including, without limitation:

•we will have additional cash requirements to support the payment of interest on our outstanding indebtedness;

•increases in our outstanding indebtedness and leverage may increase our vulnerability to adverse changes in general economic and industry conditions, as well as to competitive pressure;

•our ability to obtain additional financing for working capital, capital expenditures, general corporate and other purposes may be reduced;

•our flexibility in planning for, or reacting to, changes in our business and our industry may be reduced; and

•our flexibility to make acquisitions and develop technology may be limited.

Our ability to make payments of principal and interest on our indebtedness depends upon our future performance, which will be subject to general economic conditions and financial, business and other factors affecting our consolidated operations, many of which are beyond our control. If we are unable to generate sufficient cash flow from operations in the future to service our debt and meet our other cash requirements, we may be required, among other things:

•to seek additional financing in the debt or equity markets;

•to refinance or restructure all or a portion of our indebtedness;

•to sell selected assets or businesses; or

•to reduce or delay planned capital or operating expenditures.

Such measures might not be sufficient to enable us to service our debt and meet our other cash requirements. In addition, any such financing, refinancing or sale of assets might not be available at all or on economically favorable terms.

Sales outside of the U.S. for the year ended December 31, 2025 accounted for approximately 24% of our net sales. Our financial statements reflect translation of items denominated in non-U.S. currencies to U.S. dollars. Therefore, if the U.S. dollar strengthens in relation to the principal non-U.S. currencies from which we derive revenue as compared to a prior period, our U.S. dollar-reported revenue and income will effectively be decreased to the extent of the change in currency valuations and vice-versa. For the year ended December 31, 2025, foreign currency translations did not have a significant impact on our net sales. Fluctuations in foreign currency exchange rates, most notably the strengthening of the U.S. dollar against the euro, could have a material adverse effect on our reported revenue and income in future periods.

In the normal course of our business, we may access credit markets for general corporate purposes, which may include repayment of indebtedness, acquisitions, additions to working capital, repurchase of shares and capital expenditures. Although we expect to have sufficient liquidity to meet our foreseeable needs, our access to and the cost of capital could be negatively impacted by disruptions in the credit markets, which have occurred in the past and made financing terms for borrowers unattractive or unavailable. These factors may make it more difficult or expensive for us to access credit markets if the need arises. In addition, these factors may make it more difficult for our suppliers to meet demand for their products or for prospective customers to commence new projects, as customers and suppliers may experience increased costs of debt financing or difficulties in obtaining debt financing. Disruptions in the financial markets in the past have had adverse effects on other areas of the economy and have led to a slowdown in general economic activity that may adversely affect our businesses. One or more of these factors could adversely affect our business, financial condition, results of operations and cash flows.

Our credit agreements and indentures contain customary financial covenants, including those that limit the amount of our debt, which may restrict the operations of our business and our ability to incur additional debt to finance acquisitions. Our ability to meet the financial covenants can be affected by events beyond our control, and we cannot provide assurance that we will meet those tests. A breach of any of these covenants could result in a default under our credit agreements or indentures. Upon the occurrence of an event of default under any of our credit facilities or indentures, the lenders or trustees could elect to declare all amounts outstanding thereunder to be immediately due and payable and, in the case of credit facility lenders, terminate all commitments to extend further credit. If the lenders or trustees accelerate the repayment of borrowings, we cannot provide assurance that we will have sufficient assets to repay our credit facilities and our other indebtedness. Furthermore, acceleration of any obligation under any of our material debt instruments will permit the holders of our other material debt to accelerate their obligations, which could have a material adverse effect on our financial condition.

We may increase our debt or raise additional capital in the future, subject to restrictions in our debt agreements. If our cash flow from operations is less than we anticipate, if our cash requirements are more than we expect, or if we intend to finance acquisitions, we may require more financing. However, debt or equity financing may not be available to us on acceptable terms, if at all. If we incur additional debt or raise equity through the issuance of additional capital shares, the terms of the debt or capital shares issued may give the holders rights, preferences and privileges senior to those of holders of our ordinary shares, particularly in the event of liquidation. The terms of the debt may also impose additional and more stringent restrictions on our operations than we currently have. If we raise funds through the issuance of additional equity, the percentage ownership of existing shareholders in our company would decline. If we are unable to raise additional capital when needed, our financial condition could be adversely affected.

Unfavorable changes in the ratings that rating agencies assign to our debt may ultimately negatively impact our access to the debt capital markets and increase the costs we incur to borrow funds. If ratings for our debt are downgraded, our access to the debt capital markets may become restricted. Additionally, our credit agreements generally include an increase in interest rates if the ratings for our debt are downgraded. To the extent that our interest rates increase, our interest expense will increase, which could adversely affect our financial condition, results of operations and cash flows.

While we believe that we should be able to maintain a worldwide effective corporate tax rate that is competitive in our industry, we cannot give any assurance as to what our effective tax rate will be in the future, because of, among other things, uncertainty regarding the tax policies of the jurisdictions where we operate. Our actual effective tax rate may vary from our expectation and that variance may be material. Also, the tax laws of the U.S., the U.K., Ireland and other jurisdictions could change in the future, and such changes could cause a material change in our worldwide effective corporate tax rate. For example, the Organization for Economic Co-operation and Development introduced an international tax framework under Pillar II (the "Pillar II framework") which includes a global minimum tax of 15%. The Pillar II framework has been implemented by several jurisdictions, including jurisdictions in which we operate, with effect from January 1, 2024. Countries continue to announce changes in their tax laws and regulations based on the Pillar II framework. While we continue to evaluate the impact of these legislative changes as additional guidance becomes available, uncertainty remains regarding the timing and interpretation by tax authorities in affected jurisdictions. In addition, legislative or administrative action could be taken by the U.S., the U.K., Ireland or the EU which could override tax treaties or modify tax statutes or regulations upon which we expect to rely, limit the availability of tax benefits or deductions we currently claim or otherwise affect the taxes imposed on our worldwide operations and materially adversely affect our effective tax rate. We cannot predict the outcome of any specific legislative proposals. If proposals were enacted that had the effect of disregarding our incorporation in Ireland or limiting our ability as an Irish company to maintain tax residency in the U.K. and take advantage of the tax treaties among the U.S., the U.K. and Ireland, we could be subject to increased taxation, which could materially adversely affect our financial condition, results of operations, cash flows or our effective tax rate in future reporting periods.

We are incorporated in Ireland and we are an Irish tax resident under Irish domestic law unless we are regarded as being resident elsewhere (and not Ireland) under the terms of a double tax treaty. Under domestic U.K. law, a company that is centrally managed and controlled in the U.K. is regarded as resident in the U.K. for taxation purposes unless it is treated as resident in another jurisdiction pursuant to any appropriate double tax treaty with the U.K. Other jurisdictions may also seek to assert taxing jurisdiction over us.

Effective for tax periods beginning on or after November 1, 2019, where a company is treated as tax resident under the domestic laws of both the U.K. and Ireland, the Double Tax Convention between the U.K. and Ireland (the “Convention”) signed on June 2, 1976, and as modified by paragraph 1 of Article 4 of the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting (the “Multilateral Instrument” or “MLI”) provides that the residence of a dual-resident entity should be determined by way of mutual agreement between the Irish Revenue Commissioners and His Majesty’s Revenue Commissioners. The tie-breaker test provides that, in cases of dual residence, the competent authorities of the two states shall determine by mutual agreement the territory of which the person shall be deemed to be resident for purposes of the Convention.

Our application under the Mutual Agreement Procedure provided for in Article 24 of the Convention (as amended pursuant to the MLI) seeking confirmation that we will continue to be tax resident solely in the U.K. was approved by the competent authorities of the U.K. and Ireland effective December 31, 2019.

It is possible that in the future, whether as a result of a change in law or the practice of any relevant tax authority or as a result of any change in the conduct of our affairs, we could become, or be regarded as having become, resident in a jurisdiction other than the U.K. If we cease to be resident in the U.K. and become resident in another jurisdiction, we may be subject to U.K. exit charges, and could become liable for additional tax charges in the other jurisdiction (including dividend withholding taxes or corporate income tax charges). If we were to be treated as resident in more than one jurisdiction, we could be subject to taxation in multiple jurisdictions. If, for example, we were considered to be a tax resident of Ireland, we could become liable for Irish corporation tax and any dividends paid by us could be subject to Irish dividend withholding tax.

It may not be possible to enforce court judgments obtained in the U.S. against us in Ireland based on the civil liability provisions of the U.S. federal or state securities laws. In addition, there is some uncertainty as to whether the courts of Ireland would recognize or enforce judgments of U.S. courts obtained against us or our directors or officers based on the civil liabilities provisions of the U.S. federal or state securities laws or hear actions against us or those persons based on those laws. We have been advised that the U.S. currently does not have a treaty with Ireland providing for the reciprocal recognition and enforcement of judgments in civil and commercial matters. Therefore, a final judgment for the payment of money rendered by any U.S. federal or state court based on civil liability, whether or not based solely on U.S. federal or state securities laws, would not automatically be enforceable in Ireland.

As an Irish company, we are governed by the Companies Act 2014, which differs in some material respects from laws generally applicable to U.S. corporations and shareholders, including, among others, differences relating to interested director and officer transactions and shareholder lawsuits. Likewise, the duties of directors and officers of an Irish company generally are owed to the company only. Shareholders of Irish companies generally do not have a personal right of action against directors or officers of the company and may exercise such rights of action on behalf of the company only in limited circumstances. Accordingly, holders of our securities may have more difficulty protecting their interests than would holders of securities of a corporation incorporated in a jurisdiction of the U.S.

In addition, our articles of association provide that the Irish courts have exclusive jurisdiction to determine any and all derivative actions in which a holder of nVent ordinary shares asserts a claim in the name of nVent, actions asserting a claim of breach of a fiduciary duty of any of the directors of nVent and actions asserting a claim arising pursuant to any provision of Irish law or our articles of association. Under Irish law, the proper claimant for wrongs committed against nVent, including by our directors, is considered to be nVent itself. Irish law permits a shareholder to initiate a lawsuit on behalf of a company such as nVent only in limited circumstances and requires court permission to do so.

Under Irish law, we must have authority from our shareholders to issue any ordinary shares, including shares that are part of our authorized but unissued share capital. In addition, unless authorized by its shareholders, when an Irish company issues shares for cash to new shareholders, it is required first to offer those shares on the same or more favorable terms to existing shareholders on a pro-rata basis. If we are unable to obtain these authorizations from our shareholders, or are otherwise limited by the terms of our authorizations, our ability to issue ordinary shares under our equity compensation plans and, if applicable, to facilitate funding acquisitions or otherwise raise capital could be adversely affected.

Transfers of nVent ordinary shares effected by means of the transfer of book entry interests in the Depository Trust Company ("DTC") will not be subject to Irish stamp duty. However, if you hold your nVent ordinary shares directly, rather than beneficially through DTC, any transfer of your nVent ordinary shares could be subject to Irish stamp duty (currently at the rate of 1 percent of the higher of the price paid or the market value of the shares acquired). Payment of Irish stamp duty is generally a legal obligation of the transferee.

We currently intend to pay (or cause one of our affiliates to pay) stamp duty in connection with share transfers made in the ordinary course of trading by a seller who holds shares directly to a buyer who holds the acquired shares beneficially. In other cases we may, in our absolute discretion, pay (or cause one of our affiliates to pay) any stamp duty. Our constitution provides that, in the event of any such payment, we (i) may seek reimbursement from the buyer, (ii) will have a lien against the shares acquired by such buyer and any dividends paid on such shares and (iii) may set-off the amount of the stamp duty against future dividends on such shares. Parties to a share transfer may assume that any stamp duty arising in respect of a transaction in nVent ordinary shares has been paid unless one or both of such parties is otherwise notified by us.

Irish capital acquisitions tax (“CAT”) could apply to a gift or inheritance of nVent ordinary shares irrespective of the place of residence, ordinary residence or domicile of the parties. This is because nVent ordinary shares will be regarded as property situated in Ireland. The person who receives the gift or inheritance has primary liability for CAT. Gifts and inheritances passing between spouses are exempt from CAT. Children have a tax-free threshold which Irish Revenue typically updates annually in respect of taxable gifts or inheritances received from their parents.

We cannot predict the prices at which nVent ordinary shares may trade. The market price of nVent ordinary shares may fluctuate widely, depending on many factors, some of which may be beyond our control, including:

•actual or anticipated fluctuations in our results of operations due to factors related to our business;

•success or failure of our business strategy;

•our quarterly or annual earnings, or those of other companies in our industry;

•our ability to obtain third-party financing as needed;

•announcements by us or our competitors of significant acquisitions or dispositions;

•changes in accounting standards, policies, guidance, interpretations or principles;

•changes in earnings estimates by us or securities analysts or our ability to meet those estimates;

•the operating and share price performance of other comparable companies or of companies in industries that are our customers;

•investors' perceptions of us;

•natural or other environmental disasters that investors believe may affect us;

•overall market fluctuations;

•results from any material litigation, including government investigations or environmental liabilities;

•changes in laws and regulations affecting our business; and

•general economic conditions and other external factors.

Stock markets in general have experienced volatility that has often been unrelated to the operating performance of a particular company. These broad market fluctuations could have a material adverse effect on our share price.

Our ability to sustain and grow our business requires us to hire, retain and develop a highly skilled and diverse management team and workforce. Failure to ensure that we have the depth and breadth of personnel with the necessary skill set and experience, or the loss of key employees, could impede our ability to deliver our growth objectives and execute our strategy.

If operations at any of our manufacturing facilities or those of our suppliers were to be disrupted as a result of significant equipment failures, natural disasters, earthquakes, power outages, fires, explosions, terrorism, military conflicts, international hostilities, cybersecurity incidents, adverse weather conditions, labor disputes, public health epidemics or other catastrophic events or events outside of our control, we may be unable to fill customer orders and otherwise meet customer demand for our products. In addition, these types of events may negatively impact consumer, commercial and industrial spending in impacted regions or, depending on the severity, globally. As a result, any of such events could have a material adverse effect on our business, financial condition, results of operations and cash flows. Interruptions in production, in particular at our manufacturing facilities, could increase our costs and reduce our sales. Any interruption in production capability could require us to make substantial capital expenditures to fill customer orders. We maintain property damage insurance that we believe to be adequate to provide for reconstruction of facilities and equipment, as well as business interruption insurance to mitigate losses resulting from any production interruption or shutdown caused by an insured loss. However, any recovery under our insurance policies may not offset the lost sales or increased costs that may be experienced during the disruption of operations, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

None.

We have implemented a comprehensive cybersecurity program designed to protect the confidentiality, integrity, and availability of our information systems and data. The program is aligned with the National Institute of Standards and Technology (NIST)

Cybersecurity Framework and zero trust model, incorporates industry best practice standards, and includes policies, standards, procedures, controls and technology platforms that help manage cybersecurity risk.

Our cybersecurity program includes the following capabilities:

Our Board of Directors oversees cybersecurity risk management and is supported by the Audit and Finance Committee of the Board (the "Audit Committee"). The Audit Committee interacts with the Executive Leadership Team ("ELT"), including our Chief Technology Officer ("CTO"), and other members of management with respect to cybersecurity matters. The Board of Directors and the Audit Committee receive periodic reports from management on the effectiveness of the cybersecurity program and any material cybersecurity incidents that have occurred. The Board of Directors and the Audit Committee work with management to help ensure that our cybersecurity program is effective in addressing the risks associated with cybersecurity threats and are committed to continuously improving our cybersecurity program to stay apprised of emerging threats. The CTO oversees our cybersecurity program, including assessing and managing material risks from cybersecurity threats. The Chief Information Security Officer ("CISO") reports to the CTO and leads the cybersecurity program and team.

The CTO has served in various roles in technology for over 25 years and in information security including product security for over a decade. The CTO holds a PhD in engineering and degrees in technology and management. The CISO has served in various roles in information technology and information security for over 25 years, including serving as a cybersecurity leader for global public companies for over a decade. The CISO holds a degree in technology.

We have processes in place to assess, identify, and manage material risks from cybersecurity threats. We track cybersecurity risk as an enterprise risk through our enterprise-wide risk management ("ERM") framework. The Board of Directors is actively involved in oversight of our ERM framework and receives regular reports on risks, including cybersecurity risks. We engage third parties to conduct threat assessments, information system penetration tests, and simulation exercises to validate and further mature our cybersecurity program, the results of which are reported to the Executive Leadership Team, including CTO, and the Board of Directors. We maintain cybersecurity insurance coverage to help mitigate the financial impact of a cybersecurity incident.

We deploy technical safeguards that are designed to protect our information systems from cybersecurity incidents, including firewalls, intrusion prevention and detection systems, anti-malware functionality and access controls, all of which are evaluated and improved through vulnerability assessments and cybersecurity threat intelligence.

We have established and maintain comprehensive incident response and business continuity plans that address our response to, and mitigation and remediation of, a cybersecurity incident, which includes the support of external cyber-specialist resources when deemed necessary, in addition to managed services to support our Security Operations Center function. We have implemented controls and procedures that provide for the prompt escalation of cybersecurity incidents to the ELT, and the Board of Directors when appropriate, so that decisions regarding the public disclosure and reporting of such incidents can be made by management in a timely manner.

We maintain a comprehensive, risk-based approach to assessing and overseeing cybersecurity risks presented by third parties, including vendors, service providers and other external users of our systems, as well as the systems of third parties that could adversely impact our business in the event of a cybersecurity incident affecting those third-party systems.

We have implemented a security awareness and training program designed to educate employees on the importance of information security and to help them identify and respond to potential security incidents. The program includes annual required cybersecurity training for professional employees, role-based cybersecurity training, and a phishing awareness program for all employees. Additionally, the ELT and Board of Directors have conducted cybersecurity incident and response simulation exercises.

Previous cybersecurity incidents have not materially affected us, including our business strategy, results of operations or financial condition. However, risks from cybersecurity threats, including but not limited to exploitation of vulnerabilities, ransomware, denial of service, supply chain disruption, or other similar incidents may materially affect us, including our execution of business strategy, reputation, results of operations and/or financial condition. See Item 1A, Risk Factors, “Increased cybersecurity threats and computer crime pose a risk to our systems, networks, products and services, which expose us to potential regulatory, financial and reputational risks.” for a discussion of cybersecurity risks.

Our principal office is located in leased premises in London, U.K., and our management office in the U.S. is located in leased premises in Minneapolis, Minnesota.

Our key operations are conducted in manufacturing and distribution facilities throughout the world. The following is a summary of our principal manufacturing and distribution properties:

We believe that our production facilities are suitable for their purpose and are adequate to support our businesses.

We have been made parties to a number of actions filed or have been given notice of potential claims relating to the conduct of our business, including those pertaining to commercial disputes, product liability, asbestos, environmental, safety and health, patent infringement and employment matters.

While we believe that a material impact on our financial position, results of operations or cash flows from any such future claims or potential claims is unlikely, given the inherent uncertainty of litigation, a remote possibility exists that a future adverse ruling or unfavorable development could result in future charges that could have a material adverse impact. We do and will continue to periodically reexamine our estimates of probable liabilities and any associated expenses and receivables and make appropriate adjustments to such estimates based on experience and developments in litigation. As a result, the current estimates of the potential impact on our financial position, results of operations and cash flows for the proceedings and claims described in the notes to our consolidated financial statements could change in the future.

We have been named as defendant, target or a potentially responsible party ("PRP") in a number of environmental clean-ups relating to our current or former businesses. We may be named as a PRP at other sites in the future for existing businesses, as well as both divested and acquired businesses. In addition to clean-up actions brought by governmental authorities, private parties could bring personal injury or other claims due to the presence of, or exposure to, hazardous substances.

Certain environmental laws impose liability on current or previous owners or operators of real property for the cost of removal or remediation of hazardous substances at their properties or at properties at which they have disposed of hazardous substances. Our accruals for environmental matters are recorded on a site-by-site basis when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. It can be difficult to estimate reliably the final costs of investigation and remediation due to various factors. In our opinion, the amounts accrued are appropriate based on facts and circumstances as currently known. As of December 31, 2025, our recorded reserves for environmental matters were not material. We do not anticipate these environmental conditions will have a material adverse effect on our financial position, results of operations or cash flows. However, unknown conditions, new details about existing conditions or changes in environmental requirements may give rise to environmental liabilities that will exceed the amount of our current reserves and could have a material adverse effect in the future.

We are subject to various product liability lawsuits and personal injury claims. A substantial number of these lawsuits and claims are insured and accrued for by Tonka Bay, a captive insurance subsidiary of nVent. Tonka Bay records a liability for these claims based on actuarial projections of ultimate losses. For all other claims, accruals covering the claims are recorded, on an undiscounted basis, when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on existing information. The accruals are adjusted periodically as additional information becomes available. We have not experienced significant unfavorable trends in either the severity or frequency of product liability lawsuits or personal injury claims.

Our ordinary shares are listed for trading on the New York Stock Exchange and trade under the symbol "NVT." As of December 31, 2025, there were 11,116 shareholders of record.

The timing, declaration and payment of future dividends to holders of our ordinary shares will depend upon many factors, including our financial condition and results of operations, the capital requirements of our businesses, industry practice and any other relevant factors.

The following information under the caption "Share Performance Graph" in this ITEM 5 of this Annual Report on Form 10-K is not deemed to be "soliciting material" or to be "filed" with the Securities and Exchange Commission or subject to Regulation 14A or 14C under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or to the liabilities of Section 18 of the Exchange Act and will not be deemed to be incorporated by reference into any filing under the Securities Act of 1933, as amended, or the Exchange Act, except to the extent we specifically incorporate it by reference into such a filing.

The following graph sets forth the cumulative total shareholder return on our ordinary shares from December 31, 2020, assuming the investment of $100 and the reinvestment of all dividends since that date to December 31, 2025. The graph also contains for comparison purposes the S&P Mid Cap 400 Index and the S&P Mid Cap 400 Industrials Index, assuming the same investment level and reinvestment of dividends. By virtue of our market capitalization, we are a component of the S&P Mid Cap 400 Index. On the basis of our size and diversity of businesses, we believe the S&P Mid Cap 400 Industrials Index is an appropriate published industry index for comparison purposes.

The terms "us," "we," "our," "the Company" or "nVent" refer to nVent Electric plc. nVent is a leading global provider of electrical connection and protection solutions. We believe our inventive electrical solutions enable safer systems and ensure a more secure world. We connect and protect some of the world's most critical electrical systems to make them safer, more efficient and resilient. We design, manufacture, market, install and service high performance products and solutions that connect and protect mission critical equipment, buildings and essential processes. We have a comprehensive portfolio of bus systems, cable management, control buildings, cooling solutions, both liquid and air, electrical connections, enclosures, equipment protection, power connections and power management solutions, and switchgear systems, and we are recognized globally for quality, reliability and innovation.

We classify our operations into business segments based primarily on types of products offered and markets served. We operate across two segments: Systems Protection and Electrical Connections, which represented approximately 67% and 33% of total revenues during 2025, respectively. In 2025, we renamed our Enclosures segment to Systems Protection and our Electrical & Fastening Solutions segment to Electrical Connections.

•Systems Protection—The Systems Protection segment provides innovative solutions to help protect electronics, systems and data in mission critical applications, including data centers, that improve resiliency and energy efficiency. Our standard and custom protective enclosures, cooling solutions, both liquid and air, control buildings, switchgear systems and power distribution solutions help protect operating environments for mission critical applications in infrastructure, industrial and commercial verticals.

•Electrical Connections—The Electrical Connections segment provides innovative solutions that connect power and data infrastructure. Our offerings enhance end-user safety, reduce installation time and provide resiliency for critical systems. Our bus systems, cable management, electrical connections and solutions, and power connections help make electrical systems safe, efficient and resilient, and are used across commercial and residential, infrastructure and industrial verticals.

On May 18, 2023, as part of our Electrical Connections reporting segment, we completed the acquisition of ECM Investors, LLC, the parent of ECM Industries, LLC ("ECM Industries"), for approximately $1.1 billion in cash. ECM Industries is a leading provider of high-value electrical connectors, tools and test instruments and cable management. The purchase price was funded primarily through borrowings under the 2033 Notes and 2023 Term Loan Facility (as defined below).

On July 16, 2024, we completed the acquisition of Trachte, LLC ("Trachte") as part of our Systems Protection reporting segment, for approximately $0.7 billion in cash. Trachte is a leading manufacturer of engineered control building solutions designed to protect critical infrastructure assets. The purchase price was funded primarily through borrowings under the 2024 Term Loan Facility and Revolving Credit Facility (as defined below).

On January 30, 2025, we completed the sale of the Thermal Management business to BCP VI Summit Holdings LP (as assignee of BCP Acquisitions LLC), an affiliate of funds managed by Brookfield Asset Management, for $1.6 billion in net cash proceeds, subject to certain customary purchase price adjustments. The results of the Thermal Management business have been presented as discontinued operations in our Consolidated Financial Statements for all periods presented. The assets and liabilities of this business have been presented as held for sale in the Consolidated Balance Sheets for all periods presented prior to the sale. The Thermal Management business was previously disclosed as a stand-alone reporting segment. For further details, see ITEM 8, Note 6 of the Notes to the Consolidated Financial Statements.

On May 1, 2025, we completed the acquisition of the enclosures, switchgear and bus systems businesses of Avail Infrastructure Solutions (the "Electrical Products Group") for approximately $1.0 billion. We funded the purchase price for the acquisition with available cash on hand. The Electrical Products Group is a leading provider of infrastructure solutions, designed to help ensure safe and reliable electrical operations primarily in the infrastructure vertical, including power utilities and data centers. We operate the Electrical Products Group predominantly within our Systems Protection reporting segment.

The following trends and uncertainties affected our financial performance in 2024 and 2025, and are reasonably likely to impact our results in the future:

•During 2024 and 2025, we experienced general inflationary increases, primarily related to labor, transportation and raw material costs. In addition, we continue to monitor and evaluate recently implemented tariffs, and the potential imposition of modified or additional tariffs. We may experience increased supply chain challenges, inflationary cost increases, and economic uncertainty due to the rapid changes in global trade policies. The effects from new tariffs imposed in 2025 did not have a material impact on our financial results in 2025 due to mitigating actions. We have taken pricing actions, and may take additional pricing actions going forward, and implemented, and plan to continue to implement, supply chain optimization and other productivity improvements that have helped, and could continue to help, offset expected cost increases. Given the uncertainty regarding the scope and duration of tariffs and other changes in trade policies, the potential impact remains uncertain, but we expect inflationary cost increases, including impacts related to tariffs, to continue in 2026 and beyond, which could negatively impact our results of operations.

•Our global operations make our effective tax rate sensitive to significant tax law changes. The Organization for Economic Co-operation and Development introduced an international tax framework under Pillar II (the "Pillar II framework") which includes a global minimum tax of 15%. The Pillar II framework has been implemented by several jurisdictions, including jurisdictions in which we operate, with effect from January 1, 2024, which resulted in an increase to our effective tax rate. Countries continue to announce changes in their tax laws and regulations based on the Pillar II framework. While we continue to evaluate the impact of these legislative changes as additional guidance becomes available, uncertainty remains regarding the timing and interpretation by tax authorities in affected jurisdictions.

•The converging megatrends of the electrification of everything, sustainability and digitalization, including the increased use of artificial intelligence, have led to sales growth, particularly in the infrastructure vertical, which includes our data centers business that is primarily in our Systems Protection segment. We expect these megatrends to continue and drive sales growth in 2026 and beyond.

•We have invested in innovation and new products, which has contributed to sales growth. We expect continued investment in new products to further drive sales growth in 2026 and beyond.

In 2026, our operating objectives include the following:

•Achieving differentiated revenue growth through focus on higher growth verticals, new products and innovation, global expansion and acquisitions;

•Deploying capital strategically to drive growth and value creation;

•Integrating recent acquisitions with our existing operations;

•Driving operational excellence through lean and agile, with specific focus on our digital transformation and supply chain resiliency;

•Optimizing our technological capabilities to increasingly generate innovative new and connected products and advance digital transformation;

•Enhancing and supporting employee engagement, development and retention; and

•Executing our sustainability strategy focused on People, Products, Planet and Governance.

The consolidated results of operations were as follows:

N.M. Not Meaningful

The components of the change in consolidated net sales were as follows:

•sales of $489.9 million in 2025 as a result of the Electrical Products Group and Trachte acquisitions; and

•organic sales growth contribution of approximately 12.0% from our infrastructure business in 2025 from 2024, which includes selective increases in selling prices.

•inflationary increases, including the impacts related to tariffs, primarily related to raw materials and labor costs, compared to 2024; and

•investments in capacity to drive growth.

•higher sales volume resulting in increased leverage on fixed expenses; and

•increased productivity as a result of supply chain management and manufacturing efficiencies.

•organic sales growth resulting in increased leverage on fixed expenses; and

•savings generated from restructuring and other productivity initiatives.

•intangible amortization expense of $147.1 million in 2025 compared to $94.7 million in 2024 as a result of the Electrical Products Group and Trachte acquisitions;

•inflationary increases impacting our labor costs, professional fees and other administrative costs; and

•investments in capacity, new products and digital to drive growth.

•the repayment of certain outstanding term loan facilities during 2025; and

•interest income earned on the cash proceeds from the sale of the Thermal Management business.

In 2025 and 2024, we recognized a pre-tax, non-cash pension and other post-retirement mark-to-market gain of $12.9 million and $0.1 million, respectively.

In 2024, we recorded $12.5 million of income related to the release of a guarantee liability.

•$92.8 million of non-cash expense recorded in 2024 related to the establishment of valuation allowances on deferred tax assets related to tax-deductible statutory losses in Luxembourg initially established in 2023.

•increased earnings in higher tax rate jurisdictions.

•the gain on the sale of the Thermal Management business, net of transaction costs, of $435.3 million, partially offset by tax expense recorded as a result of the sale of $152.7 million.

The summary that follows provides a discussion of the results of operations of both of our reportable segments (Systems Protection and Electrical Connections). Both of these segments comprise various product offerings that serve multiple end users.

We evaluate performance based on net sales and reportable segment income ("segment income") and use a variety of ratios to measure performance of our reporting segments. Segment income represents operating income, which includes certain corporate overhead allocations, exclusive of intangible amortization, acquisition related expenses, costs of restructuring activities, impairments and other unusual non-operating items.

The net sales, segment income and segment income as a percentage of net sales for Systems Protection were as follows:

The components of the change in Systems Protection net sales from the prior period were as follows:

•sales of $443.9 million in 2025 as a result of the Electrical Products Group and Trachte acquisitions; and

•organic sales growth contribution of approximately 16.0% from our infrastructure business in 2025 from 2024, which includes selective increases in selling prices and growth in the data centers business.

The components of the change in Systems Protection segment income as a percentage of net sales from the prior period were as follows:

•inflationary increases, including the impacts related to tariffs, primarily related to labor costs and raw materials, compared to 2024; and

•investments in capacity, new products and digital to drive growth.

•organic sales growth resulting in increased leverage on fixed expenses; and

•increased productivity as a result of supply chain management and manufacturing efficiencies.

The net sales, segment income and segment income as a percentage of net sales for Electrical Connections were as follows:

The components of the change in Electrical Connections net sales from the prior period were as follows:

•organic sales growth contribution of approximately 5.5% from our infrastructure business in 2025 from 2024, which includes selective increases in selling prices; and

•sales of $46.0 million in 2025 as a result of the Electrical Products Group acquisition.

The components of the change in Electrical Connections segment income as a percentage of net sales from the prior period were as follows:

The 1.3 percentage point decrease in segment income for Electrical Connections as a percentage of net sales in 2025 from 2024 was primarily the result of:

•inflationary increases, including the impacts related to tariffs, primarily related to raw materials and labor costs, compared to 2024; and

•investments in digital, selling and marketing to drive growth.

•organic sales growth resulting in increased leverage on fixed expenses; and

•increased productivity as a result of supply chain management and manufacturing efficiencies.

The primary source of liquidity for our business is cash flows provided by operations. We expect to continue to have cash requirements to support working capital needs and capital expenditures, to pay interest and service debt and to pay dividends to shareholders quarterly. We believe we have the ability and sufficient capacity to meet these cash requirements by using available cash, internally generated funds and borrowing under committed credit facilities. We are focused on increasing our cash flow, while continuing to fund our research and development, sales and marketing and capital investment initiatives. Our intent is to maintain investment grade metrics and a solid liquidity position. As of December 31, 2025, we had $237.5 million of cash on hand, of which $72.7 million is held in certain countries in which the ability to repatriate is limited due to local regulations or significant potential tax consequences.

We experience seasonal cash flows primarily due to increased demand for Electrical Connections products during the spring and summer months in the Northern Hemisphere.

Net cash provided by operating activities from continuing operations was $649.0 million in 2025. Net cash provided by operating activities in 2025 primarily reflects net income from continuing operations of $634.5 million, net of non-cash depreciation, amortization, changes in deferred taxes and pension and other-post retirement mark-to-market gain, partially offset by a $23.0 million increase in net working capital.

Net cash provided by operating activities from continuing operations was $501.0 million in 2024. Net cash provided by operating activities in 2024 primarily reflects net income from continuing operations of $472.0 million, net of non-cash depreciation, amortization, changes in deferred taxes and pension and other post-retirement mark-to-market gain, and a $3.5 million decrease in net working capital.

Net cash used for investing activities from continuing operations was $1,063.7 million in 2025, which primarily related to cash paid for the Electrical Products Group acquisition of $979.6 million and capital expenditures of $93.3 million. Net cash provided by investing activities from discontinued operations of $1,584.5 million in 2025 primarily relates to proceeds from the sale of the Thermal Management business, net of transaction costs and cash transferred.

Net cash used for investing activities from continuing operations was $750.8 million in 2024, which primarily related to cash paid for the Trachte acquisition of $677.7 million, net of cash acquired, and capital expenditures of $74.0 million.

Net cash used for financing activities was $968.4 million in 2025, which primarily related to repayments of long-term debt of $873.3 million, share repurchases of $253.1 million and dividends paid of $130.4 million, partially offset by proceeds from long-term debt of $275.0 million.

Net cash provided by financing activities was $146.2 million in 2024, which primarily related to proceeds from long-term debt of $500.0 million, partially offset by dividends paid of $126.8 million, repayments of long-term debt of $126.5 million and share repurchases of $100.0 million.

In November 2021, nVent Finance issued $300.0 million aggregate principal amount of 2.750% fixed rate senior notes due 2031 (the "2031 Notes").

Interest on the 2028 Notes is payable semi-annually in arrears on April 15 and October 15 of each year, and interest on the 2031 Notes and 2033 Notes is payable semi-annually in arrears on May 15 and November 15 of each year.

In February 2026, we entered into a supplemental indenture to the indenture governing the Notes as a result of which nVent Electric plc and Hoffman Schroff Holdings, Inc. fully and unconditionally and jointly and severally guarantee the Notes of nVent Finance (together with nVent Electric plc and Hoffman Schroff Holdings, Inc., the "Obligor Group"). nVent Electric plc is a holding company that has no independent assets or operations unrelated to its investments in consolidated subsidiaries. nVent Finance is a holding company that has no independent assets or operations unrelated to its investments in consolidated subsidiaries and the issuance of the Notes and other external debt. Hoffman Schroff Holdings, Inc. is a United States holding company and a 100 percent-owned indirect subsidiary of nVent Electric plc that has no independent assets or operations unrelated to its investments in consolidated subsidiaries and the guarantees of the Notes and other external debt. nVent Electric plc’s principal source of cash flow, including cash flow to make payments on the Notes pursuant to the guarantees, is dividends from its subsidiaries. nVent Finance's principal source of cash flow, including to make payments on the Notes, is interest income from its subsidiaries. Hoffman Schroff Holdings, Inc.'s principal source of cash flow, including to make payments on the Notes pursuant to the guarantees, is interest income from its subsidiaries. None of the other subsidiaries of any of the Obligor Group are under any direct obligation to pay or otherwise fund amounts due on the Notes or the guarantees, whether in the form of dividends, distributions, loans or other payments. In addition, there may be statutory and regulatory limitations on the payment of dividends from certain subsidiaries of the Obligor Group. If such subsidiaries are unable to transfer funds to the Obligor Group and sufficient cash or liquidity is not otherwise available, the Obligor Group may not be able to make principal and interest payments on their outstanding debt, including the Notes or the guarantees.

The following table presents summarized financial information as of December 31, 2025 for the Obligor Group on a combined basis after elimination of (i) intercompany transactions and balances among the guarantors and issuer and (ii) equity in earnings from and investments in any subsidiary that is a non-Guarantor or issuer.

(1) Includes assets due from non-guarantor subsidiaries of $0.7 million.

(2) Includes assets due from non-guarantor subsidiaries of $1,592.1 million.

(3) Includes liabilities due to non-guarantor subsidiaries of $0.2 million.

(4) Includes liabilities due to non-guarantor subsidiaries of $17.9 million.

The Obligor Group does not have material results of operations on a combined basis.

In June 2025, nVent and its subsidiaries nVent Finance and Hoffman Schroff Holdings, Inc. entered into an amended and restated credit agreement (the "Credit Agreement") with a syndicate of banks providing for a five-year $275.0 million senior unsecured term loan facility (the "2025 Term Loan Facility") and a five-year $600.0 million senior unsecured revolving credit facility (the "Revolving Credit Facility" and, together with the 2025 Term Loan Facility, the "Senior Credit Facilities"). The Credit Agreement amended and restated in its entirety the 2021 Credit Agreement. Borrowings under the Revolving Credit Facility are permitted from time to time during the full five-year term of the Revolving Credit Facility. nVent Finance has the option to request to increase the Revolving Credit Facility in an aggregate amount of up to $300.0 million, subject to customary conditions, including the commitment of the participating lenders.

Borrowings under the Senior Credit Facilities bear interest at a rate equal to an adjusted base rate, the Term Secured Overnight Financing Rate ("SOFR"), Euro Interbank Offer Rate (“EURIBOR”), Sterling Overnight Index Average (“SONIA”) or, solely for swingline loans denominated in Euros, the Euro Short Term Rate ("ESTR"), plus, in each case, an applicable margin. The applicable margin will be based on, at nVent Finance’s election, nVent's net leverage ratio or public debt rating.

In April 2023, nVent and nVent Finance entered into a loan agreement providing for another unsecured term loan facility of $300.0 million for five years (the "2023 Term Loan Facility"), which was used to fund the acquisition of ECM Industries. In 2025, nVent repaid the remainder of the borrowings on the 2023 Term Loan Facility.

In June 2024, nVent and nVent Finance entered into a loan agreement providing for an additional senior unsecured term loan facility of $500.0 million for two years (the "2024 Term Loan Facility"). In July 2024, we partially financed the acquisition of Trachte using the 2024 Term Loan Facility. In 2025, nVent repaid the remainder of the borrowings on the 2024 Term Loan Facility.

Our debt agreements contain certain financial covenants, the most restrictive of which are in the Senior Credit Facilities, including that we may not permit (i) the ratio of our consolidated debt (net of our consolidated unrestricted cash in excess of $5.0 million but not to exceed $250.0 million) to our consolidated net income (excluding, among other things, non-cash gains and losses) before interest, taxes, depreciation, amortization and non-cash share-based compensation expense ("EBITDA") on the last day of any period of four consecutive fiscal quarters (each a "testing period") to exceed 3.75 to 1.00 (or, at nVent Finance's election and subject to certain conditions, 4.25 to 1.00 for four testing periods in connection with certain material acquisitions) and (ii) the ratio of our EBITDA to our consolidated interest expense for the same period to be less than 3.00 to 1.00. In addition, subject to certain qualifications and exceptions, the Senior Credit Facilities also contain covenants that, among other things, restrict our ability to create liens, merge or consolidate with another person, make acquisitions and incur subsidiary debt. As of December 31, 2025, we were in compliance with all financial covenants in our debt agreements, and there is no material uncertainty about our ongoing ability to meet those covenants.

On May 17, 2024, the Board of Directors authorized the repurchase of our ordinary shares up to a maximum dollar limit of $500.0 million (the "2024 Authorization"). The 2024 Authorization began on July 23, 2024 and expires on July 22, 2027.

During the year ended December 31, 2025, we repurchased 4.8 million of our ordinary shares for $253.1 million under the 2024 Authorization.

As of December 31, 2025, we had $146.9 million available for share repurchases under the 2024 Authorization.

Dividends paid per ordinary share were $0.80 and $0.76 for the years ended December 31, 2025 and 2024, respectively.

Under Irish law, the payment of future cash dividends and repurchases of shares may be paid only out of nVent Electric plc's "distributable reserves" on its statutory balance sheet. nVent Electric plc is not permitted to pay dividends out of share capital, which includes share premiums. Distributable reserves may be created through the earnings of the Irish parent company and through a reduction in share capital approved by the Irish High Court. Distributable reserves of nVent Electric plc are not linked to a generally accepted accounting principles in the United States of America ("GAAP") reported amount (e.g., retained earnings). Our distributable reserve balance was $2.1 billion and $2.4 billion as of December 31, 2025 and 2024, respectively.

In general, we require cash to fund working capital investments, acquisitions, capital expenditures, debt and interest payments, taxes, dividends and share repurchases.

Our material contractual cash requirements as of December 31, 2025 include principal and interest on long-term debt as well as payments for lease liabilities. Servicing these obligations includes the following estimated cash outflows from December 31, 2025:

We also incur purchase obligations in the ordinary course of business that are enforceable and legally binding. We have contractual purchase obligations of $69.8 million for 2026, which represent commitments for raw materials to be utilized in the normal course of business for which all significant terms have been confirmed. Contractual purchase obligations beyond 2026 are not material.

The total gross liability for uncertain tax positions at December 31, 2025 was estimated to be $10.3 million. We record penalties and interest related to unrecognized tax benefits in Provision (benefit) for income taxes and Net interest expense, respectively in the Consolidated Statements of Operations and Comprehensive Income, which is consistent with our past practices. As of December 31, 2025, we have liabilities of $1.5 million for the possible payment of penalties and $1.5 million related to the possible payment of interest expense, which are recorded in Other current liabilities in the Consolidated Balance Sheet.

In addition to measuring our cash flow generation or usage based upon operating, investing and financing classifications included in the Consolidated Statements of Cash Flows, we also measure our free cash flow. Free cash flow is a non-GAAP financial measure that we use to assess our cash flow performance. We believe free cash flow is an important measure of liquidity because it provides us and our investors a measurement of cash generated from operations that is available to pay dividends, make acquisitions, repay debt and repurchase shares.

In addition, free cash flow is used as a criterion to measure and pay annual incentive compensation. Our measure of free cash flow may not be comparable to similarly titled measures reported by other companies.

The following table is a reconciliation of free cash flow:

We have been, and in the future may be, made parties to a number of actions filed or have been, and in the future may be, given notice of potential claims relating to the conduct of our business, including those pertaining to commercial or contractual disputes, product liability, environmental, safety and health, patent infringement and employment matters.

While we believe that a material impact on our consolidated financial position, results of operations or cash flows from any such future claims or potential claims is unlikely, given the inherent uncertainty of litigation, a remote possibility exists that a future adverse ruling or unfavorable development could result in future charges that could have a material impact. We do and will continue to periodically re-examine our estimates of probable liabilities and any associated expenses and receivables and make appropriate adjustments to such estimates based on experience and developments in litigation. As a result, the current estimates of the potential impact on our consolidated financial position, results of operations and cash flows for the proceedings and claims described in ITEM 8, Note 18 of the Notes to the Consolidated Financial Statements could change in the future.

We have adopted various accounting policies to prepare the consolidated financial statements in accordance with GAAP. Our significant accounting policies are more fully described in ITEM 8, Note 1 of the Notes to Consolidated Financial Statements. Certain of our accounting policies require the application of significant judgment by management in selecting the appropriate assumptions for calculating financial estimates. By their nature, these judgments are subject to an inherent degree of uncertainty. These judgments are based on our historical experience, terms of existing contracts, our observance of trends in the industry and information available from other outside sources, as appropriate. We consider an accounting estimate to be critical if:

•it requires us to make assumptions about matters that were uncertain at the time we were making the estimate; and

•changes in the estimate or different estimates that we could have selected would have had a material impact on our financial condition or results of operations.

Assets and liabilities acquired in a business combination are recorded at their estimated fair values at the acquisition date. Goodwill is recorded when the purchase price exceeds the estimated fair value of the net identifiable tangible and intangible assets acquired. Estimates of intangible asset fair value represent management’s best estimate of assumptions and about future events and uncertainties, including significant judgments related to future cash flows, discount rates, margin and revenue growth assumptions including royalty rates and customer attrition rates, and others. Inputs used are generally obtained from historical data supplemented by current and anticipated market conditions and growth rates. If the actual results differ from the estimates and judgments used in these fair values, the amounts recorded in the consolidated financial statements could result in a possible impairment of the intangible assets and goodwill or require acceleration of the amortization expense of finite-lived intangible assets.

Allocations of the purchase price for acquisitions are based on estimates of the fair value of the net assets acquired and are subject to adjustment upon finalization of the purchase price allocation. During this measurement period, which may be up to one year from the acquisition date, we will adjust assets or liabilities if new information is obtained about facts and circumstances that existed as of the acquisition date that, if known, would have resulted in the recognition of those assets and liabilities as of that date. All changes that do not qualify as measurement period adjustments are included in current period earnings.

The fair value of each reporting unit is determined using a discounted cash flow analysis and market approach. Projecting discounted future cash flows requires us to make significant estimates regarding future revenues and expenses, projected capital expenditures, changes in working capital and the appropriate discount rate. Use of the market approach consists of comparisons to comparable publicly-traded companies that are similar in size and industry. Actual results may differ from those used in our valuations.

Determining the fair value of the reporting units required the use of significant judgment, including assumptions about future revenues and expenses, capital expenditures and changes in working capital and discount rates, which are based on our annual operating plan and long-term business plan. These plans take into consideration numerous factors including historical experience, anticipated future economic conditions, and growth expectations for the industries and end markets in which the reporting unit participates. The level of judgment and estimation is inherently high. These assumptions are determined over a six year long-term planning period. The six year growth rates for revenues and operating profits vary for each reporting unit being evaluated. Revenues and operating profit beyond 2031 are projected to grow at a perpetual growth rate of 3.0% to 3.5%.

Discount rate assumptions for each reporting unit take into consideration our assessment of risks inherent in the future cash flows of the respective reporting unit and our weighted-average cost of capital. We utilized a 9.5% discount rate for each reporting unit in determining the discounted cash flows in our fair value analysis.

There was no impairment expense recorded in 2025, 2024 or 2023 related to goodwill. A 10% decrease in the fair values determined in the quantitative impairment assessment for each of the reporting units would not have changed our determination that the fair value of each reporting unit was in excess of its carrying value for 2025.

There is a risk that changes in economic and operating conditions affecting the assumptions used in our impairment tests could adversely affect future estimates or fair value and result in additional goodwill or other intangible asset impairment expense in the future.

Our primary identifiable intangible assets include: customer relationships, trade names, proprietary technologies and patents. Identifiable intangibles with definite lives are amortized and those identifiable intangibles with indefinite lives are not amortized. Identifiable intangible assets that are subject to amortization are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Identifiable intangible assets not subject to amortization are tested for impairment annually or more frequently if events warrant. We complete our annual impairment test during the fourth quarter each year for those identifiable assets not subject to amortization.

The impairment test for trade names consists of a comparison of the fair value of the trade name with its carrying value. Fair value is measured using the relief-from-royalty method. This method assumes the trade name has value to the extent that the owner is relieved of the obligation to pay royalties for the benefits received from them. This method requires us to estimate the future revenue for the related brands, the appropriate royalty rate and the weighted-average cost of capital. We utilized a royalty rate ranging from 2.0% to 5.5% for each trade name in our fair value analysis.

There was no impairment expense recorded in 2025, 2024 or 2023 related to identifiable intangible assets. A 10% decrease in the fair values determined in the quantitative impairment assessment for each of the trade names would not have changed our determination that the fair value of each trade name was in excess of its carrying value for 2025.

We sponsor defined-benefit pension plans and a post-retirement health plan. The defined benefit plans cover certain non-U.S. employees and retirees and the pension benefits are based principally on an employee's years of service and/or compensation levels near retirement.

The amounts recognized in our consolidated financial statements related to our defined-benefit pension and other post-retirement plans are determined from actuarial valuations. Inherent in these valuations are assumptions, including: expected return on plan assets, discount rates and rate of increase in future compensation levels. These assumptions are updated annually and are disclosed for our defined-benefit pension plans and post-retirement health plan in ITEM 8, Note 13 to the Notes to Consolidated Financial Statements. Differences in actual experience or changes in assumptions may affect our pension and other post-retirement obligations and future expense.

We recognize changes in the fair value of plan assets and net actuarial gains or losses for pension and other post-retirement benefits annually in the fourth quarter each year (“mark-to-market adjustment”) and, if applicable, in any quarter in which an interim remeasurement is triggered. Net actuarial gains and losses occur when the actual experience differs from any of the various assumptions used to value our pension and other post-retirement plans or when assumptions change, as they may each year. The primary factors contributing to actuarial gains and losses each year are (1) changes in the discount rate used to value pension and other post-retirement benefit obligations as of the measurement date and (2) differences between the expected and the actual return on plan assets. This accounting method also results in the potential for volatile and difficult to forecast mark-to-market adjustments. Mark-to-market adjustments resulted in a pre-tax gain of $12.9 million in 2025, a pre-tax gain of $0.1 million in 2024, and a pre-tax loss of $13.4 million in 2023. The remaining components of pension expense, including service and interest costs and estimated return on plan assets, are recorded on a quarterly basis as ongoing pension expense.

The expected rates of return on our pension plan assets ranged from 0.50% to 3.25%, 1.00% to 3.25% and 1.00% to 3.75% in 2025, 2024 and 2023, respectively. The expected rate of return is designed to be a long-term assumption that may be subject to considerable year-to-year variance from actual returns. In developing the expected long-term rate of return, we considered our historical returns, with consideration given to forecasted economic conditions, our asset allocations, input from external consultants and broader long-term market indices. Any difference in the expected rate and actual returns will be included with the actuarial gain or loss recorded in the fourth quarter when our plans are remeasured.

A 0.25 percentage point change in the discount rates used to measure our pension and other post-retirement benefit plans is estimated to have an impact on our total projected benefit obligation of approximately $4.5 million. A 0.25 percentage point change in the assumed rate of return on pension assets or discount rates for our pension and other post-retirement benefit plans is estimated to have no material impact on our ongoing pension expense. These estimates exclude any potential mark-to-market adjustments.

In determining taxable income for financial statement purposes, we must make certain estimates and judgments. These estimates and judgments affect the calculation of certain tax liabilities and the determination of the recoverability of certain of the deferred tax assets, which arise from temporary differences between the tax and financial statement recognition of revenue and expense. In evaluating our ability to recover our deferred tax assets we consider all available positive and negative evidence including our past operating results, the existence of cumulative losses in the most recent years and our forecast of future taxable income.

In estimating future taxable income, we develop assumptions including the amount of future pre-tax operating income, the reversal of temporary differences and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates we are using to manage the underlying businesses.

We maintain valuation allowances with respect to our deferred tax assets unless it is more likely than not that all or a portion of such deferred tax assets will be realized. Our income tax expense recorded in the future may be reduced to the extent of decreases in our valuation allowances. The realization of our remaining deferred tax assets is primarily dependent on future taxable income in the appropriate jurisdiction. Any reduction in future taxable income including but not limited to any future restructuring activities may require that we record an additional valuation allowance against our deferred tax assets. An increase in the valuation allowance could result in additional income tax expense in such period and could have a significant impact on our future earnings.

Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. Management records the effect of a tax rate or law change on nVent’s deferred tax assets and liabilities in the period of enactment. Future tax rate or law changes could have a material effect on nVent’s financial condition, results of operations or cash flows.

In addition, the calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax regulations in a multitude of jurisdictions across our global operations. We perform reviews of our income tax positions on a quarterly basis and accrue for uncertain tax positions. We recognize potential liabilities and record tax liabilities for anticipated tax audit issues in the tax jurisdictions in which we operate based on our estimate of whether, and the extent to which, additional taxes will be due. These tax liabilities are reflected net of related tax loss carryforwards. As events change or resolution occurs, these liabilities are adjusted, such as in the case of audit settlements with taxing authorities. The ultimate resolution may result in a payment that is materially different from our current estimate of the tax liabilities. If our estimate of tax liabilities proves to be less than the ultimate assessment, an additional charge to expense would result. If payment of these amounts ultimately proves to be less than the recorded amounts, the reversal of the liabilities would result in tax benefits being recognized in the period when we determine the liabilities are no longer necessary. We recognize the effect of income tax positions only if those positions are more likely than not to be sustained. Recognized income tax positions are measured at the largest amount that is more likely than not to be realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.

Market risk is the potential economic loss that may result from adverse changes in the fair value of financial instruments. We are exposed to various market risks, including changes in interest rates and foreign currency rates. Periodically, we use derivative financial instruments for the purpose of hedging interest rate and currency exposures. The major accounting policies and utilization of these instruments is described more fully in ITEM 8, Note 1 of the Notes to Consolidated Financial Statements.

We conduct business in various locations throughout the world and are subject to market risk due to changes in the value of foreign currencies in relation to our reporting currency, the U.S. dollar. Periodically, we use derivative financial instruments to manage these risks. The functional currencies of our foreign operating locations are generally the local currency in the country of domicile. We manage these operating activities at the local level and revenues, costs, assets and liabilities are generally denominated in local currencies, thereby mitigating the risk associated with changes in foreign exchange. However, our results of operations and assets and liabilities are reported in U.S. dollars and thus will fluctuate with changes in exchange rates between such local currencies and the U.S. dollar.

From time to time, we may enter into foreign currency contracts to hedge certain foreign currency risks. As the majority of our foreign currency contracts have an original maturity date of less than one year, there is no material risk of fluctuations in the value of these contracts. Counterparties to all derivative contracts are major financial institutions. All instruments are entered into for other than trading purposes.

At December 31, 2025 and 2024, we had outstanding foreign currency derivative contracts, including those related to cross currency swaps that qualify as a hedge of future cash flows, with gross notional U.S. dollar equivalent amounts of $364.9 million and $259.3 million, respectively. Changes in the fair value of all derivatives that do not qualify as a hedge of future cash flows are recognized immediately in income. Gains and losses related to a hedge are deferred and recorded in the Consolidated Balance Sheets as a component of Accumulated other comprehensive loss and subsequently recognized in the Consolidated Statements of Operations and Comprehensive Income when the hedged item affects earnings.

At December 31, 2025 and 2024, we had a gross notional U.S. dollar equivalent amount of $153.0 million and $135.6 million designated as a net investment hedge for a portion of our net investment in our Euro denominated subsidiaries. The hedge is intended to reduce, but will not eliminate, the impact on our financial results of changes in the exchange rate between the Euro and the U.S. dollar. The currency risk related to the net investment hedge is measured by estimating the potential impact of a 10% change in the value of the U.S. dollar relative to the Euro. The rates used to perform this analysis were based on the market exchange rates in effect on December 31, 2025. A 10% appreciation or a 10% depreciation of the U.S. dollar relative to the Euro would result in a change in Accumulated other comprehensive loss of $15.3 million. However, the change in Accumulated other comprehensive loss would be offset by decreases or increases in the hedged net investments on our balance sheet due to currency translation.

Our debt portfolio as of December 31, 2025 was comprised of debt denominated in U.S. dollars. The debt portfolio is comprised of approximately 83% fixed-rate debt and 17% variable-rate debt. Changes in interest rates have different impacts on the fixed and variable-rate portions of our debt portfolio. A change in interest rates on the fixed portion of the debt portfolio impacts the fair value, but has no impact on interest incurred or cash flows. A change in interest rates on the variable portion of the debt portfolio impacts the interest incurred and cash flows but does not impact the net financial instrument position.

Based on the fixed-rate debt included in our debt portfolio, as of December 31, 2025, a 100 basis point increase or decrease in interest rates would result in a $56.6 million decrease or a $60.2 million increase in fair value, respectively.

Based on the variable-rate debt included in our debt portfolio as of December 31, 2025, a 100 basis point increase or decrease in interest rates would result in a $2.7 million increase or decrease in interest incurred.

Management of nVent Electric plc and its subsidiaries (the "Company") is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Securities Exchange Act of 1934. The Company's internal control over financial reporting is 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. The Company's internal control over financial reporting includes those policies and procedures that (1) pertain to 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 the 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 the effectiveness of internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2025. In making this assessment, management used the criteria for effective internal control over financial reporting described in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management believes that, as of December 31, 2025, the Company's internal control over financial reporting was effective based on those criteria.

In May 2025, the Company acquired the enclosures, switchgear and bus systems businesses of Avail Infrastructure Solutions (the "Electrical Products Group"). The Company is continuing to integrate the Electrical Products Group into its internal control over financial reporting, and management's evaluation of the effectiveness of the Company's internal control over financial reporting excluded the Electrical Products Group as of December 31, 2025. The Electrical Products Group accounted for approximately 4% of total assets, excluding acquired goodwill and identifiable intangible assets which are included within the scope of management's assessment, and approximately 9% of total net sales included within the consolidated financial statements of nVent Electric plc as of and for the fiscal year ended December 31, 2025.

Our independent registered public accounting firm, Deloitte & Touche LLP, has issued an attestation report on the Company's internal control over financial reporting as of December 31, 2025. That attestation report is set forth immediately following this management report.

 

We have audited the internal control over financial reporting of nVent Electric plc and subsidiaries (the "Company") as of December 31, 2025, 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, 2025, 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, 2025, of the Company and our report dated February 17, 2026, expressed an unqualified opinion on those financial statements.

As described in Management’s Report on Internal Control over Financial Reporting, management excluded from its assessment the internal control over financial reporting at the enclosures, switchgear and bus systems businesses of Avail Infrastructure Solutions (the "Electrical Products Group"), which was acquired on May 1, 2025, and whose financial statements constitute approximately 4% of total assets, excluding acquired goodwill and identifiable intangible assets which are included within the scope of management's assessment, and approximately 9% of total net sales included within the consolidated financial statements of nVent Electric plc as of and for the year ended December 31, 2025. Accordingly, our audit did not include the internal control over financial reporting at the Electrical Products Group.

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 Management’s Report 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.

We have audited the accompanying consolidated balance sheets of nVent Electric plc and subsidiaries (the "Company") as of December 31, 2025 and 2024, the related consolidated statements of operations and other comprehensive income, changes in equity, and cash flows, for each of the three years in the period ended December 31, 2025, 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, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, 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, 2025, 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 17, 2026, 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.

On May 1, 2025, the Company completed the acquisition of the enclosures, switchgear and bus systems businesses of Avail Infrastructure Solutions (the “Electrical Products Group”) for consideration paid of $979.6 million. The acquired business operates predominantly within the Systems Protection reporting segment. The Company accounted for the acquisition under the acquisition method of accounting for business combinations. Accordingly, the purchase price was allocated to the assets acquired and liabilities assumed based on their respective fair values, including customer relationship intangible assets of $325.2 million. Management estimated the fair values of the customer relationship intangible assets using the multi-period excess earnings method, which is a specific discounted cash flow method. The fair value determination of the Systems Protection reporting segment customer relationship intangible asset acquired required management to make significant estimates and assumptions related to future cash flows, including earnings before interest and taxes (“EBIT”) margin and revenue growth assumptions, the contributory asset charge, and the selection of the discount and customer attrition rates.

Given the significance of the Systems Protection reporting segment customer relationship intangible asset acquired and the requirement of management to make significant estimates and assumptions to estimate the fair value of this asset, we identified the valuation of the Systems Protection reporting segment customer relationship intangible asset acquired as a critical audit matter. This required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists, when performing audit procedures to evaluate the reasonableness of management’s forecasts of future cash flows, including margin and revenue growth assumptions, the contributory asset charge, and the selection of the discount and customer attrition rates for the Systems Protection reporting segment customer relationship intangible asset acquired.

Our audit procedures related to the forecasts of future cash flows, including the margin and revenue growth rates, the contributory asset charge, and the selection of the discount and customer attrition rates for the acquired Systems Protection reporting segment customer relationship intangible asset included the following, among others:

•We tested the effectiveness of controls over the valuation of the acquired customer relationship intangible asset, including management’s controls over forecasts of future cash flows, including EBIT margin and revenue growth assumptions, the contributory asset charge, and the selection of the discount and customer attrition rates.

•We assessed the reasonableness of management’s forecasts of future cash flows, including EBIT margin and revenue growth assumptions, by comparing the projections to historical results for the Electrical Products Group, certain peer companies’ historical results, and industry reports.

•With the assistance of our fair value specialists, we evaluated the reasonableness of (1) the valuation methodology, (2) the contributory asset charge and (3) the discount and customer attrition rates by:

–Testing the source information underlying the determination of the contributory asset charge and the discount and customer attrition rates.

–Comparing the selected customer attrition rate to the historical customer attrition rate observed by the Electrical Products Group.

–Testing the mathematical accuracy of the contributory asset charge and the discount and customer attrition rate calculations.

–Developing a range of independent estimates and comparing those to the discount rate and customer attrition rate selected by management.

We have served as the Company's auditor since 2017.

1.Basis of Presentation and Summary of Significant Accounting Policies

nVent Electric plc ("nVent," "we," "us," "our" or the "Company") is a leading global provider of electrical connection and protection solutions. The Company is comprised of two reporting segments: Systems Protection and Electrical Connections.

The Company was incorporated in Ireland on May 30, 2017. Although our jurisdiction of organization is Ireland, we manage our affairs so that we are centrally managed and controlled in the United Kingdom (the "U.K.") and have tax residency in the U.K.

The consolidated financial statements have been prepared in United States ("U.S.") dollars ("USD") and in accordance with accounting principles generally accepted in the United States of America ("GAAP"). Intercompany accounts and transactions have been eliminated.

Revenues, expenses, cash flows, assets and liabilities can and do vary during each quarter of the year.

On July 31, 2024, we entered into a definitive agreement to sell our Thermal Management business to BCP VI Summit Holdings LP (as assignee of BCP Acquisitions LLC), an affiliate of funds managed by Brookfield Asset Management. We completed the sale of the Thermal Management business on January 30, 2025, which resulted in $1.6 billion in net cash proceeds, subject to certain customary purchase price adjustments. As a result of the agreement, the Thermal Management business met the criteria set forth in Accounting Standards Codification ("ASC") 205-20 to be presented as a discontinued operation and the related assets and liabilities have been presented as held for sale. The Thermal Management business' results of operations and the related cash flows are reflected in Income from discontinued operations, net of tax in the Consolidated Statements of Operations and Comprehensive Income and cash flows from discontinued operations in the Consolidated Statements of Cash Flows, respectively, for all periods presented. For additional information regarding this transaction and its effect on our financial reporting, see Note 6 below.

Our fiscal year ends on December 31. We report our interim quarterly periods on a calendar quarter basis.

The preparation of our consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in these consolidated financial statements and accompanying notes, disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates include our accounting for valuation of goodwill and indefinite lived intangible assets, estimated losses on accounts receivable, estimated realizable value on excess and obsolete inventory, over-time revenue recognition, assets acquired and liabilities assumed in acquisitions, contingent liabilities, income taxes and pension and other post-retirement benefits. Actual results could differ from our estimates.

Revenue is recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for transferring those goods or providing services. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable.

When determining whether the customer has obtained control of the goods or services, we consider any future performance obligations. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in Accounting Standards Codification 606 - Revenue from Contracts with Customers. Generally, there is no post-shipping obligation on product sold other than warranty obligations in the normal and ordinary course of business, except where our products are utilized in projects where additional services such as installation are performed. The timing of satisfaction of the Company's performance obligations does not significantly vary from the typical timing of payment.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account for purposes of revenue recognition. A contract's transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The majority of our contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and, therefore, not distinct. For contracts with multiple performance obligations, stand-alone selling price is generally readily observable.

Our performance obligations are satisfied at a point in time or over time as work progresses. Revenue from products and services transferred to customers at a point in time accounted for 65%, 76% and 79% of our revenue for the years ended December 31, 2025, 2024 and 2023, respectively.

Revenue on these contracts is recognized when obligations under the terms of the contract with our customer are satisfied; generally this occurs with the transfer of control upon shipment.

Revenue from products and services transferred to customers over time accounted for 35%, 24% and 21% of our revenue for the years ended December 31, 2025, 2024 and 2023, respectively. For the majority of our revenue recognized over time, we use an input measure to determine progress towards completion. Under this method, sales and gross profit are recognized as work is performed generally based on the relationship between the actual costs incurred and the total estimated costs at completion ("the cost-to-cost method") or based on efforts for measuring progress towards completion in situations in which this approach is more representative of the progress on the contract than the cost-to-cost method. Contract costs include labor, material, overhead and, when appropriate, general and administrative expenses. Changes to the original estimates may be required during the life of the contract and such estimates are reviewed on a regular basis. Sales and gross profit are adjusted using the cumulative catch-up method for revisions in estimated total contract costs. These reviews have not resulted in adjustments that were significant to our results of operations. For performance obligations related to long-term contracts, when estimates of total costs to be incurred on a performance obligation exceed total estimates of revenue to be earned, a provision for the entire loss on the performance obligation is recognized in the period the loss is determined.

We use an output method to measure progress towards completion for certain of our Systems Protection businesses, as this method appropriately depicts performance towards satisfaction of the performance obligation. Under the output method, revenue is recognized based on number of units produced.

We apply a practical expedient to expense incremental costs of obtaining a contract when incurred because the amortization period would be less than one year. These costs primarily relate to sales commissions and are recorded in Selling, general and administrative in the Consolidated Statements of Operations and Comprehensive Income. Further, we do not adjust the promised amount of consideration for the effects of a significant financing component if we expect, at contract inception, that the period between when we transfer a promised good or service to a customer and when the customer pays for that good or service will be less than one year.

The right of return may exist explicitly or implicitly with our customers. Our return policy allows for customer returns only upon our authorization. Goods returned must be product we continue to market and must be in salable condition. When the right of return exists, we adjust the transaction price for the estimated effect of returns. We estimate the expected returns based on historical sales levels, the timing and magnitude of historical sales return levels as a percent of sales, type of product, type of customer and a projection of this experience into the future.

Our sales contracts may give customers the option to purchase additional goods or services priced at a discount. This can come in many forms, such as customer programs and incentive offerings including pricing arrangements, promotions and other volume-based incentives.

We reduce the transaction price for certain customer programs and incentive offerings including pricing arrangements, promotions and other volume-based incentives that represent variable consideration. Sales incentives given to our customers are recorded using either the expected value method or most likely amount approach for estimating the amount of consideration to which nVent shall be entitled. The expected value is the sum of probability-weighted amounts in a range of possible consideration amounts. An expected value is an appropriate estimate of the amount of variable consideration when there are a large number of contracts with similar characteristics. The most likely amount is the single most likely amount in a range of possible consideration amounts (that is, the single most likely outcome of the contract). The most likely amount is an appropriate estimate of the amount of variable consideration if the contract has limited possible outcomes.

Pricing is established at or prior to the time of sale with our customers and we record sales at the agreed-upon net selling price. However, certain of our businesses allow customers to apply for a refund of a percentage of the original purchase price if they can demonstrate sales to a qualifying end customer. We use the expected value method to estimate the anticipated refund to be paid based on historical experience and the transaction price is reduced for the probable cost of the discount.

Volume-based incentives involve rebates that are negotiated at or prior to the time of sale with the customer and are redeemable only if the customer achieves a specified cumulative level of sales or sales increase. Under these incentive programs, at the time of sale, we estimate the anticipated rebate to be paid based on forecasted sales levels. These forecasts are updated at least quarterly for each customer and the transaction price is reduced for the anticipated cost of the rebate. If the forecasted sales for a customer changes, the accrual for rebates is adjusted to reflect the new amount of rebates expected to be earned by the customer.

Amounts billed to customers for shipping and handling activities after the customer obtains control are treated as a separate performance obligation and recorded in Net sales in the Consolidated Statements of Operations and Comprehensive Income. Shipping and handling costs incurred by nVent for the delivery of goods to customers are considered a cost to fulfill the contract and are included in Cost of goods sold in the Consolidated Statements of Operations and Comprehensive Income.

Contract assets consist of unbilled amounts resulting from sales under long-term contracts when the cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer, such as when the customer retains a small portion of the contract price until completion of the contract. We typically receive interim payments on sales under long-term contracts as work progresses, although for some contracts, we may be entitled to receive an advance payment. Contract liabilities consist of advanced payments and billings in excess of revenue recognized.

Contract assets are recorded within Other current assets and contract liabilities are recorded within Other current liabilities in the Consolidated Balance Sheets.

We conduct research and development activities primarily in our own facilities, which consist primarily of the development of new products, product applications and manufacturing processes.

We consider highly liquid investments with original maturities of three months or less at the date of acquisition to be cash equivalents.

We record an allowance for doubtful accounts to reduce our receivables balance by the amount that is estimated to be uncollectible from our customers, or the expected loss. Estimates used in determining the allowance for doubtful accounts are based on historical collection experience, including write-offs and recoveries, periodic credit evaluations of our customers' financial situation and current circumstances, as well as reasonable and supportable forecasts of future economic conditions. We generally do not require collateral. Accounts receivable from one customer represented approximately 11% of total accounts receivable as of December 31, 2025. No customer receivable balance exceeded 10% of total net receivable balance as of December 31, 2024.

Inventories are stated at the lower of cost or net realizable value with substantially all inventories recorded using the first-in, first-out cost method.

Property, plant and equipment is stated at historical cost. We compute depreciation by the straight-line method based on the following estimated useful lives:

Significant improvements that add to productive capacity or extend the lives of properties are capitalized. Costs for repairs and maintenance are charged to expense as incurred. When property is retired or otherwise disposed of, the recorded cost of the assets and their related accumulated depreciation are removed from the Consolidated Balance Sheets and any related gains or losses are included in income.

We review the recoverability of long-lived assets to be held and used, such as property, plant and equipment, when events or changes in circumstances occur that indicate the carrying value of the asset or asset group may not be recoverable. The assessment of possible impairment is based on our ability to recover the carrying value of the asset or asset group from the expected future pre-tax cash flows (undiscounted and without interest charges) of the related operations. If these cash flows are less than the carrying value of such asset or asset group, an impairment loss is recognized for the difference between estimated fair value and carrying value. Impairment losses on long-lived assets held for sale are determined considering the selling price, and fair values are reduced for the cost to dispose of the assets. The measurement of impairment requires us to estimate future cash flows and the fair value of long-lived assets. There was no material impairment expense recorded in 2025, 2024 or 2023 related to long-lived assets.

The following table presents geographic Property, plant and equipment, net by region as of December 31:

The fair value of each reporting unit is determined using a discounted cash flow analysis and market approach. Determining the fair value of the reporting units required the use of significant judgment, including assumptions about future revenues and expenses, capital expenditures and changes in working capital and discount rates, which are based on our annual operating plan and long-term business plan. These plans take into consideration numerous factors including historical experience, anticipated future economic conditions, and growth expectations for the industries and end markets in which the reporting unit participates. The level of judgment and estimation is inherently high. Inputs used to estimate these fair values included significant unobservable inputs that reflect the Company’s assumptions about the inputs that market participants would use and, therefore, the fair value assessments are classified within Level 3 of the fair value hierarchy defined by the accounting guidance.

Our primary identifiable intangible assets include customer relationships, trade names, proprietary technologies and patents and backlog. Identifiable intangibles with definite lives are amortized and those identifiable intangibles with indefinite lives are not amortized. Identifiable intangible assets that are subject to amortization are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Identifiable intangible assets not subject to amortization are tested for impairment annually or more frequently if events warrant. We complete our annual impairment test during the fourth quarter each year for those identifiable assets not subject to amortization.

The impairment test for trade names consists of a comparison of the fair value of the trade name with its carrying value. Fair value is measured using the relief-from-royalty method. This method assumes the trade name has value to the extent that the owner is relieved of the obligation to pay royalties for the benefits received from them. This method requires us to estimate the future revenue for the related brands, the appropriate royalty rate and the weighted-average cost of capital. The non-recurring fair value measurement is a Level 3 measurement under the fair value hierarchy described below.

There was no impairment expense recorded in 2025, 2024 or 2023 related to identifiable intangible assets.

We use the asset and liability approach to account for income taxes. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax bases using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period when the change is enacted. We maintain valuation allowances unless it is more likely than not that all or a portion of the deferred tax assets will be realized. Changes in valuation allowances from period to period are included in our tax provision in the period of change. We recognize the effect of income tax positions only if those positions are more likely than not to be sustained. Recognized income tax positions are measured at the largest amount that is more likely than not to be realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.

We sponsor defined-benefit pension plans and a post-retirement health plan. The pension and other post-retirement benefit costs for these plans are determined from actuarial assumptions and methodologies, including discount rates and expected returns on plan assets. These assumptions are updated annually and are disclosed in Note 13.

We recognize changes in the fair value of plan assets and net actuarial gains or losses for pension and other post-retirement benefits annually in the fourth quarter each year (“mark-to-market adjustment”) and, if applicable, in any quarter in which an interim remeasurement is triggered. Net actuarial gains and losses occur when the actual experience differs from any of the various assumptions used to value our pension and other post-retirement plans or when assumptions change, as they may each year. The remaining components of pension expense, including service and interest costs and estimated return on plan assets, are recorded on a quarterly basis.

Basic earnings per share are computed by dividing net income by the weighted-average number of ordinary shares outstanding. Diluted earnings per share are computed by dividing net income by the weighted-average number of ordinary shares outstanding including the dilutive effects of ordinary share equivalents, calculated using the treasury stock method.

We recognize all derivatives, including those embedded in other contracts, as either assets or liabilities at fair value in our Consolidated Balance Sheets. If the derivative is designated and is effective as a cash flow or fair value hedge, the effective portion of changes in the fair value of the derivative are recorded in Accumulated other comprehensive loss as a separate component of equity in the Consolidated Balance Sheets and is recognized in the Consolidated Statements of Operations and Comprehensive Income when the hedged item affects earnings. If the underlying hedged transaction ceases to exist or if the hedge becomes ineffective, all changes in fair value of the related derivatives that have not been settled are recognized in current earnings. Cash flows of the derivative financial instruments are classified consistent with the underlying hedged item. For a derivative that is not designated as or does not qualify as a hedge, changes in fair value are reported in earnings immediately.

Gains and losses on net investment hedges are included in Accumulated other comprehensive loss as a separate component of equity in the Consolidated Balance Sheets.

We use derivative instruments for the purpose of hedging interest rate and currency exposures, which exist as part of ongoing business operations. We do not hold or issue derivative financial instruments for trading or speculative purposes. All other contracts that contain provisions meeting the definition of a derivative also meet the requirements for the normal purchases and normal sales scope exception. Our policy is not to enter into contracts with terms that cannot be designated as normal purchases or sales. From time to time, we may enter into short duration foreign currency contracts to hedge foreign currency risks.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities measured at fair value are classified using the following hierarchy, which is based upon the transparency of inputs to the valuation as of the measurement date:

Level 1: Valuation is based on observable inputs such as quoted market prices (unadjusted) for identical assets or liabilities in active markets.

Level 2: Valuation is based on inputs such as quoted market prices for similar assets or liabilities in active markets or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

Level 3: Valuation is based upon other unobservable inputs that are significant to the fair value measurement.

In making fair value measurements, observable market data must be used when available. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement.

The financial statements of subsidiaries located outside of the U.S. are generally measured using the local currency as the functional currency, except for certain corporate entities outside of the U.S. which are measured using USD. Assets and liabilities of these subsidiaries are translated at the rates of exchange at the balance sheet date. Income and expense items are translated at average monthly rates of exchange. The resultant translation adjustments are included in Accumulated other comprehensive loss as a separate component of equity.

In November 2024, the Financial Accounting Standards Board issued Accounting Standards Update 2024-03, "Disaggregation of Income Statement Expenses", which is intended to improve disclosures about a public business entity's expenses. It requires public entities to disaggregate specific types of expenses, including disclosures for purchases of inventory, employee compensation, depreciation, and intangible asset amortization, as well as selling expenses. The guidance is effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027 and may be adopted on a retrospective or prospective basis. We are currently evaluating the potential impact of adopting this new guidance on the related disclosures within our consolidated financial statements.

2.Revenue

We disaggregate our revenue from contracts with customers by geographic location and vertical, as we believe these best depict how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors.

Geographic net sales information, based on geographic destination of the sale, was as follows:
