Table of Contents
This section and the discussions contained in Item 1A, “Risk Factors,” and in Item 7, subheading “Critical Accounting Policies and Estimates” in this report, are intended to provide meaningful cautionary statements for purposes of the safe harbor provisions of the Act. This should not be construed as a complete list of all of the economic, competitive, governmental, technological and other factors that could adversely affect our expected consolidated financial position, results of operations or liquidity. Additional risks and uncertainties, including without limitation those not currently known to us or that we currently believe are immaterial, also may impair our business, operations, liquidity, financial condition and prospects.
Use of Non-GAAP Financial Measures
In addition to results presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”), this report may include non-GAAP financial measures. The Company believes that these non-GAAP financial measures provide additional information that is useful to investors in understanding the underlying performance and trends of the Company. Readers should be aware that non-GAAP financial measures have inherent limitations and should be cautious with respect to the use of such measures. To compensate for these limitations, we use non-GAAP measures as comparative tools, together with GAAP measures, to assist in the evaluation of our operating performance or financial condition. We calculate these measures using the appropriate GAAP components in their entirety and compute them in a manner intended to facilitate consistent period-to-period comparisons. The Company’s method of calculating these non-GAAP measures may differ from methods used by other companies. These non-GAAP measures should not be considered in isolation or as a substitute for those financial measures prepared in accordance with GAAP. Where non-GAAP financial measures are used, the most directly comparable GAAP financial measure, as well as the reconciliation to the most directly comparable GAAP financial measure, can be found in this report.

The Company’s automotive products are generally sold directly to OEMs, substantially pursuant to negotiated annual contracts, long-term supply agreements or terms and conditions as may be modified by the parties. Deliveries are subject to periodic authorizations based upon OEM production schedules. The Company typically ships its products directly from its plants to the OEMs.
Sales and Marketing
Each of the Company’s businesses within its reportable segments has its own sales function. Account executives for each of the Company’s businesses are assigned to serve specific customers for one or more businesses’ products. Account executives spend the majority of their time in direct contact with customers’ purchasing and engineering employees and are responsible for servicing existing business and for identifying and obtaining new business. Because of their close relationship with customers, account executives are able to identify and meet customers’ needs based upon their knowledge of the Company’s product design and manufacturing capabilities. Upon securing a new order, account executives participate in product launch team activities and serve as a key interface with customers. In addition, sales and marketing employees of the Company’s reportable segments often work together to explore cross-development opportunities where appropriate.
Seasonality
The Company’s operations are directly related to the automotive and commercial-vehicle industry. Consequently, the Company’s segments may experience seasonal fluctuations to the extent vehicle production slows at certain times of the year. For example, model changeovers and vacations during the summer months have generally resulted in lower sales volume in the Company’s third quarter, and in China, the Company typically experiences lower sales in the first quarter due to the Chinese New Year.
Research and Development
The Company conducts advanced propulsion research. This advanced engineering function seeks to leverage know-how and expertise across product lines to create new electrified propulsion systems and modules that can be commercialized. This function oversees the Company's investments in certain venture capital funds that provide seed money for start-up businesses developing new technologies pertinent to the automotive industry and the Company's propulsion strategies.

Raw Materials
The Company uses a variety of raw materials in the production of its products, including aluminum, copper, nickel, plastic resins, steel, magnets, certain alloy elements and semiconductor chips. Manufacturing operations for each of the Company’s operating segments are dependent upon natural gas, fuel oil and electricity.
The Company uses a variety of tactics in an attempt to limit the impact of supply shortages, tariffs, export bans and inflationary pressures. The Company’s global procurement organization works to accelerate cost reductions, purchase from lower cost regions, optimize the supply base, mitigate risk and collaborate on its buying activities. In addition, the Company uses long-term contracts, cost sharing arrangements, design changes, dual sourcing, customer buy programs and limited financial instruments to help control costs. The Company intends to use similar measures in 2026 and beyond. Refer to Note 17, “Financial Instruments,” to the Consolidated Financial Statements in Item 8 of this report for information related to the Company’s hedging activities.
For 2026, the Company believes there will be continued inflationary pressures in certain raw materials, labor and energy. While the Company believes inflation will decrease in some areas, it does not expect to see “deflation,” which means that it expects supplier costs to remain elevated relative to prior years. Supplies of raw materials are adequate and available from multiple sources to support the Company’s manufacturing requirements.
Regulations
The Company operates in a constantly evolving global regulatory environment and is subject to numerous and varying regulatory requirements for its product performance and material content. The Company’s practice is to identify potential regulatory and quality risks early in the design and development process and proactively manage them throughout the product lifecycle through the use of routine assessments, protocols, standards, performance measures and audits. New regulations and changes to existing regulations are managed in collaboration with the Company’s OEM customers and implemented through its global systems and procedures designed to ensure compliance with existing laws and regulations. The Company demonstrates material content compliance through the International Material Data System (“IMDS”), which is the automotive industry material data system. In the IMDS, all materials used for automobile manufacturing are archived and maintained to meet the obligations placed on the automobile manufacturers, and thus on their suppliers, by national and international standards, laws and regulations.
The Company works collaboratively with a number of stakeholder groups, including government agencies, such as the National Highway Traffic Safety Administration, its customers and its suppliers to proactively engage in federal, state and international public policy processes.
Refer to Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” for a discussion of the impact of environmental regulations on the Company’s business. Also, see Item 1A, “Risk Factors.”

Item 1A. Risk Factors
Investors should carefully consider the following risk factors and other information included in this report. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impact our business operations. If any of the following risks occur, our business, including our financial performance, financial condition, operating results and cash flows, could be adversely affected. In such an event, the market price of our common stock could decline, and you could lose all or part of your investment.
Risks related to our strategy
Our portfolio strategy may prove unsuccessful.
Our strategy is to focus on profitable growth across our technology-focused product portfolio that supports electric, hybrid and combustion vehicles by growing our eProducts as well as continuing our focus on Foundational products. Our balanced portfolio is particularly critical as the automotive industry continues to see electric vehicle adoption volatility across different regions.
We may not prove successful in our strategy due to many factors, including any of the risks identified in the paragraphs that follow, failure to develop new products that our customers will purchase, technology changes that could render our products obsolete, or the introduction of new technology to which we do not have access, among other things.
Our future success is dependent upon us making the right investments at the right times, with the right customers who can rapidly adapt to the market, to support product development in areas of evolving vehicle technologies. We have made, and expect to continue to make, significant investments to grow our eProducts. If the overall adoption of electric vehicles continues to be slower as compared to our expectations, we may not only fail to realize expected rates of return on our existing investments, we may also incur further losses on such investments. Further, if we invest in relationships with the wrong customers or in the wrong markets, then we may still fail to realize expected returns.
We expect to continue to pursue business ventures, acquisitions, and strategic alliances that leverage our technology capabilities and enhance our customer base, geographic representation, and scale to complement our current businesses. We regularly evaluate potential growth opportunities. While we believe that such transactions are an integral part of our long-term strategy, there are risks and uncertainties related to these activities. Assessing a potential growth opportunity involves extensive due diligence. However, the amount of information we can obtain about a potential growth opportunity can be limited, and we can give no assurance that past or future business ventures, acquisitions, and strategic alliances will positively affect our financial performance or will perform as planned. Assessing a price for potential transactions is inexact.
As noted, we conduct certain of our operations through joint ventures, where we may share ownership and management responsibilities with one or more partners that may not share our goals and objectives. Operating a joint venture may require additional organizational formalities as well as the sharing of information and decision making with our partners. Additional risks associated with joint ventures include one or more partners failing to satisfy contractual obligations, the ability to enforce such obligations, conflicts arising between us and any of our partners, a change in the ownership of any of our partners and less of an ability to control compliance with applicable rules and regulations, including the Foreign Corrupt Practices Act and related rules and regulations.
Goodwill and indefinite-lived intangible assets, which are subject to periodic impairment evaluations, represent a significant portion of our total assets. An impairment charge on these assets could have a material adverse impact on our financial condition and results of operations.
17

Table of Contents
We have recorded goodwill and indefinite-lived intangible assets related to acquisitions. We periodically assess these assets to determine if they are impaired. Significant negative industry or macroeconomic trends, disruptions to our business, inability to effectively integrate acquired businesses, unexpected significant changes or planned changes in use of the assets, dispositions and market capitalization declines may impair these assets.
We review goodwill and indefinite-lived intangible assets for impairment either annually or whenever changes in circumstances indicate that the carrying value may not be recoverable. The risk of impairment to goodwill and indefinite-lived intangible assets is higher during the early years following an acquisition as the fair values of these assets align very closely with what was paid to acquire the reporting units to which these assets are assigned. As a result, the difference between the carrying value of the reporting unit and its fair value (typically referred to as “headroom”) is smaller at the time of acquisition. Until this headroom grows over time, due to business growth or lower carrying value of the reporting unit, a relatively small decrease in reporting unit fair value can trigger impairment charges. When impairment charges are triggered, they tend to be material due to the size of the assets involved. Future acquisitions could present similar risks. Any charges relating to such impairments, such as those recorded for the years ended December 31, 2025 and 2024, could adversely affect our results of operations in the periods recognized.
The failure to realize the expected benefits of acquisitions and other risks associated with acquisitions could adversely affect our business.
The success of our acquisitions is dependent, in part, on our ability to realize the expected benefits from combining our businesses and businesses that we acquire. To realize these anticipated benefits, both companies must be successfully combined, which is subject to our ability to consolidate operations, corporate cultures and systems and to eliminate redundancies and costs. If we are unsuccessful in combining companies, the anticipated benefits of the acquisitions may not be realized fully or at all or may take longer to realize than expected. Further, there is potential for unknown or inestimable liabilities relating to the acquired businesses. In addition, the actual integration may result in additional and unforeseen expenses, which could reduce the anticipated benefits of the acquisitions.
The combination of independent businesses is a complex, costly and time-consuming process that requires significant management attention and resources. It is possible that the integration process could result in the loss of key employees, the disruption of our operations, the inability to maintain or increase our competitive presence, inconsistencies in standards, controls, procedures and policies, difficulties in achieving anticipated cost savings, synergies, business opportunities and growth prospects from the acquisition, the diversion of management’s attention to integration matters and/or difficulties in the assimilation of employees and corporate cultures. Any or all of these factors could adversely affect our ability to maintain relationships with customers and employees or to achieve the anticipated benefits of the acquisition and could have an adverse effect on the combined company. In addition, many of these factors are outside of our control, and any one of these factors could result in increased costs, decreases in the amount of expected revenues, unanticipated risks and liabilities associated with the acquired business, and additional diversion of management’s time and energy, which could materially adversely impact our business, financial condition and results of operations. In addition, if the expected benefits of an acquisition do not meet the expectations of investors or securities analysts, the market price of our common stock may decline.
We may not be able to execute dispositions of assets or businesses successfully.
When we decide to dispose of assets or a business, we may have difficulty finding buyers or alternative exit strategies on acceptable terms in a timely manner, which could delay our ability to achieve our strategic objectives. We may also dispose of a business at a price or on terms that are less desirable
18

Table of Contents
than we had anticipated. Buyers of the assets or business may from time to time agree to indemnify us for operations of such businesses after the closing. We cannot be assured that any of these indemnification provisions will fully protect us, and, as a result, may face unexpected liabilities that adversely affect our business, financial condition and results of operations. In addition, we may experience fewer synergies than expected or even negative synergies from separating a business, and the impact of the disposition on our financial results may be larger than projected.
After reaching an agreement for the disposition of a business, we are subject to satisfaction of pre-closing conditions as well as necessary regulatory and governmental approvals on acceptable terms, which, if not satisfied or obtained, may prevent us from completing the transaction. Such regulatory and governmental approvals may be required in jurisdictions around the world, and any delays in the timing of such approvals could materially delay or prevent the transaction.
Risks related to our industry
Conditions in the automotive industry may adversely affect our business.
Our financial performance depends on conditions in the global automotive industry. Automotive and truck production and sales are cyclical and sensitive to general economic conditions, geopolitical and trade-related issues and other factors, including interest rates, declines in the availability of consumer credit, increased borrowing costs and consumer spending and preferences. Economic declines that result in significant reduction in automotive or truck production would result in a decline in the production levels of our major customers and, by extension, in our sales to OEMs which would adversely affect our business, results of operations, cash flows and financial condition.
We face strong competition.
We compete globally with a number of other manufacturers and distributors that produce and sell similar products. Price, quality, delivery, technological innovation, engineering development and program launch support are the primary elements of competition. Our competitors include vertically integrated units of our major OEM customers, as well as a large number of independent domestic and international suppliers. Additionally, our competitors include start-ups that may be well funded, with the result that they could have more operational and financial flexibility than we have. A number of our competitors are larger than we are, and some competitors have greater financial and other resources than we do. Although many OEMs have indicated that they will continue to rely on outside suppliers, a number of major OEM customers have indicated their intent to insource certain components that we produce, and many do manufacture products for their own uses that directly compete with our products. These OEMs have elected and could elect to manufacture such products for their own uses in place of the products we currently supply. Our traditional OEM customers, faced with intense international competition, have continued to expand their global sourcing of components. As a result, we have experienced competition from suppliers in other parts of the world that enjoy economic advantages, such as lower labor costs, lower health care costs, lower tax rates and, in some cases, export or raw materials subsidies. Increased competition could adversely affect our business. In addition, any of our competitors may foresee the course of market development more accurately than we do, develop products that are superior to our products, produce similar products at a cost that is lower than our cost, or adapt more quickly than we do to new technologies or evolving customer requirements. As a result, our products may not be able to compete successfully with our competitors' products, and we may not be able to meet the growing demands of customers. These trends may adversely affect our sales as well as the profit margins on our products.
19

Table of Contents
If we do not respond appropriately, the evolution of the automotive industry could adversely affect our business.
The automotive industry is increasingly focused on improved vehicle efficiency and reduced emissions, including the development of hybrid and electric vehicles, largely as a result of changing consumer preferences and increasingly stringent global regulatory requirements related to climate change, and of advanced driver-assistance technologies, with the goal of developing and introducing a commercially viable, fully automated driving experience. There has also been an increase in consumer preferences for mobility-on-demand services, such as car and ride sharing, as opposed to automobile ownership, which may result in a long-term reduction in the number of vehicles per capita. In addition, some industry participants are exploring transportation through alternatives to automobiles. These evolving areas have also attracted increased competition from entrants outside the traditional automotive industry. While we are focused on driving growth through our ability to capitalize on certain potential trends, such as the move toward hybrid and electric vehicles, some of the focuses and trends are not part of our product line or strategy. If we do not continue to innovate and develop, or acquire, new and compelling products that capitalize upon new technologies, including artificial intelligence (“AI”) and machine learning, or improve in response to OEM and consumer preferences, this could have an adverse impact on our results of operations.
We may be subject to potential governmental investigations and related proceedings relating to vehicle emissions standards.
In recent years, within the automotive industry, there have been governmental investigations and related proceedings relating to alleged or actual violations of vehicle emissions standards. Any potential alleged violations by BorgWarner of existing or future emissions standards could result in government investigations and other legal proceedings, the recall of one or more of our products, negotiated remedial actions, fines, disgorgement of profits, restricted product offerings, reputational harm or a combination of any of those items. Any of these actions could have a material adverse effect on our business and financial results.
Risks related to our business
We are under substantial pressure from OEMs to reduce the prices of our products.
There is substantial and continuing pressure on OEMs to reduce costs, including costs of products we supply. Virtually all automakers have implemented aggressive price-reduction initiatives and objectives each year with their suppliers, and such actions are expected to continue in the future. OEM customers expect annual price reductions in our business. To maintain our profit margins, we seek price reductions from our suppliers, improved production processes to increase manufacturing efficiency, and streamlined product designs to reduce costs, and we attempt to develop new products, the benefits of which support stable or increased prices. Price reductions have impacted the Company’s sales and profit margins and are expected to continue to do so in the future. Our ability to pass through increased raw material or other inflationary costs to our OEM customers is limited, with cost recovery often less than 100% and often on a delayed basis. Inability to reduce or offset costs in an amount equal to annual price reductions, increases in raw material costs, and increases in employee wages and benefits could have an adverse effect on our business and results of operations.
20

Table of Contents
We continue to face volatile costs of commodities used in the production of our products and elevated levels of inflation.
We use a variety of commodities (including aluminum, copper, nickel, plastic resins, steel, other raw materials and energy) and materials purchased in various forms such as castings, powder metal, forgings, stampings and bar stock. The costs and availability of raw materials can fluctuate due to factors beyond our control. Increasing commodity costs negatively impact our operating margins and results. While we seek to alleviate the impact of increasing costs by including material pass-through provisions in our customer contracts wherever possible and by selectively hedging certain commodity exposures, we may not be successful in these efforts. The discontinuation or lessening of our ability to pass through or hedge increasing commodity costs could adversely affect our business.
From time to time, commodity prices may also fall rapidly. If this happens, suppliers may withdraw capacity from the market until prices improve, which may cause periodic supply interruptions. The same may be true of transportation carriers and energy providers. If these supply interruptions occur, it could adversely affect our business.
Many global economies, including the United States, have experienced and continue to experience elevated levels of inflation more generally, which have driven an increase in input costs. Following non-contractual negotiations, we reached cost-recovery agreements with various customers in 2024, 2023 and 2022, but these agreements did not enable us to recover 100 percent of our increased costs, and as a result, our operating margins were negatively impacted. Elevated levels of inflation could adversely affect our business.
We may not achieve some or all of the expected benefits of our restructuring plans and our restructuring actions may adversely affect our business.
We have taken, are taking, and may in the future take restructuring actions to realign and resize our production capacity and cost structure to meet current and projected operational and market requirements. Implementation of any restructuring action may be costly and disruptive to our business, and we may not be able to realize the cost savings, operational improvements and estimated workforce reductions that we anticipate within the projected timing or at all. We are also subject to the risks of labor unrest, negative publicity and business disruption in connection with our restructuring actions. Additionally, as a result of restructuring initiatives, we may experience a loss of continuity, loss of accumulated knowledge and/or inefficiency, loss of key employees and/or other retention issues during transitional periods. Restructuring can require a significant amount of time and focus, which may divert attention from operating and growing our business. Moreover, we base projections of any cost savings or other benefits associated with our restructuring actions on current business operations and market dynamics, and various factors, including but not limited to our evolving business models, future investment decisions, market environment and technology landscape, could significantly impact the success of these actions. Refer to Note 4, “Restructuring,” to the Consolidated Financial Statements for more information.
Changes in administrative policy on the part of the U.S. or other countries, including the imposition of or increases in tariffs, changes to existing trade agreements and any resulting changes in international trade relations, may have an adverse effect on us.
In 2025, the U.S. announced significant tariffs on imports from a broad range of countries, including the European Union, Canada, Mexico and China. These tariffs have increased the cost of raw materials and components we purchase, and to the extent the tariffs announced to date or announced in the future become or remain effective and are maintained, these tariffs would likely further increase the cost of raw materials and components we purchase. The imposition of tariffs by the U.S. has resulted in retaliatory tariffs from other countries, including China, which has increased and would continue to increase the cost
21

Table of Contents
of products we sell. Additionally, ongoing changes in U.S. and foreign government trade policies, including potential modifications to existing trade agreements and further restrictions on free trade, could introduce additional uncertainty with respect to trade policies and government regulations affecting international trade. Tariffs or retaliatory tariffs announced to date or announced in the future, current trade tensions, any escalation of trade tensions, additional tariffs, retaliatory measures by foreign governments, shifts in U.S. or international trade policies or related uncertainties affecting the conduct of business and consumer spending could continue to adversely impact our supply chain, increase costs of components and materials and reduce demand for our products, directly or indirectly due to negative effects on our customers, the U.S. economy, the economies of other countries in which we operate or the global economy, any or all of which could have a material adverse effect on our business, financial condition, results of operations and cash flows. Further, the duration and scope of these potential effects are unknown. Although we have taken steps to attempt to mitigate these effects, including entering into contractual agreements with our customers to recover tariff impacts incurred to date, and are considering others to counter the impact of such tariffs on our business, financial condition and results of operations, there is no assurance that we will continue to be successful in recovering such costs from our customers or implementing the other mitigation efforts without disrupting our business, operations and financial performance.
In addition to potential increases in customs duties and tariffs in the U.S. and other countries, the United States-Mexico-Canada Agreement ("USMCA") is subject to renewal in 2026. There can be no assurance that the USMCA will be renewed or, if renewed, any newly negotiated terms in the USMCA will not adversely affect our business. Also, China presents unique risks to U.S. automotive manufacturers due to the strain in U.S.-China relations and the level of integration with key components in our global supply chain. It remains unclear what additional actions the current U.S. administration may take with respect to trade issues involving China and other countries.
In 2025, we imported approximately $918 million in value to the U.S. Approximately 68% of that value originated in Mexico, approximately 9% originated in Canada and approximately 6% originated in South Korea.
We use important intellectual property in our business. If we are unable to protect our intellectual property or if a third party makes assertions against us or our customers relating to intellectual property rights, our business could be adversely affected.
We own important intellectual property, including patents, trademarks, copyrights, and trade secrets and are involved in numerous licensing arrangements. Our intellectual property plays an important role in maintaining our competitive position in a number of the markets that we serve. Our competitors may develop technologies that are similar or superior to our proprietary technologies or design around the patents we own or license. Further, as we expand our operations in jurisdictions where the enforcement of intellectual property rights is less robust, the risk of others duplicating our proprietary technologies increases, despite efforts we undertake to protect them. Our inability to protect or enforce our intellectual property rights or claims that we are infringing intellectual property rights of others could adversely affect our business and our competitive position.
We are subject to business continuity risks associated with increasing centralization of our information technology (“IT”) systems.
22

Table of Contents
To improve efficiency and reduce costs, we have regionally centralized the information systems that support our business processes such as invoicing, payroll, and general management operations. If the centralized systems are disrupted or disabled, key business processes could be interrupted, which could adversely affect our business.
A failure of or disruption in our information technology infrastructure, including a disruption related to cybersecurity, could adversely impact our business and operations.
We rely on the capacity, reliability and security of our IT systems and infrastructure to operate our business. IT systems are vulnerable to disruptions, including those resulting from natural disasters, cyber-attacks or failures in third-party provided services. Disruptions and attacks on our IT systems pose a risk to our business operations and our ability to protect our systems, networks and communications, and the confidentiality and availability of third-party and internal data, including our employees. Some cyber-attacks depend on human error or manipulation, including phishing attacks, social engineering schemes or ransomware to gain access to systems or carry out disbursement of funds or other frauds, which raise the risks from such events and the costs associated with protecting against such attacks. Although we have implemented security policies, processes, and layers of defense designed to help identify and protect against intentional and unintentional misappropriation or corruption of our systems and information and disruptions of our operations (and, to date, we are not aware that we have experienced a cybersecurity incident that has materially affected our business strategy, results of operations, or financial condition), we have been, and likely will continue to be, subjected to such attacks or disruptions which could be material. Future attacks or disruptions could potentially lead to the inappropriate disclosure of confidential information, including our intellectual property or employee data, improper use of our systems and networks, access to and manipulation and destruction of our or third-party data, production downtimes, lost revenues, inappropriate disbursement of funds and both internal and external supply shortages. In addition, we may be required to incur significant costs to protect against damage caused by such attacks or disruptions in the future. These consequences could cause significant damage to our reputation, affect our relationships with our customers and suppliers, lead to claims against us and ultimately adversely affect our business.
Additionally, some of our products contain complex digital technologies designed to support today’s increasingly connected vehicles. Although we continue to employ capabilities, processes and other security measures designed to reduce risks of cyber-attacks against our products, such measures may not provide absolute security and may not sufficiently mitigate all potential risks under all scenarios. Failure of such products to effectively protect against attacks targeted at our products can negatively impact our brand and our business or results of operation.
Further, we continually update and expand our information technology systems to enable us to run our business more efficiently, including the potential incorporation of AI solutions into our information systems and processes. The increasing use and evolution of advanced technology solutions creates potential risks for loss or misuse of Company data that forms part of any data set that was collected, used, stored or transferred to run our business. Any unintentional dissemination or intentional destruction of confidential information stored in our or our third-party providers' systems, portable media or storage devices may result in significantly increased business and security recovery costs, a damaged reputation, administrative penalties, or costs related to defending legal claims. The use of AI in the development of our products and services could also cause loss or theft of intellectual property as well as subject us to risks related to intellectual property infringement or misappropriation, data privacy and cybersecurity. In addition, if the content, analyses, or recommendations that AI programs assist in producing are or are alleged to be deficient, inaccurate, or biased, then our business, financial condition, and results of operations and our reputation may be adversely affected. We also face risks of competitive disadvantage if our competitors more effectively use AI to drive internal efficiencies or create new or enhanced products
23

Table of Contents
or services that we are unable to compete against on cost, quality or other attributes. Any of these risks could negatively impact our business or results of operation.
Our business success depends on attracting and retaining qualified personnel.
Our ability to sustain and grow our business requires us to hire, retain and develop a highly skilled and diverse management team and workforce worldwide. In particular, any unplanned turnover or inability to attract and retain key employees and employees with engineering, technical and software capabilities in numbers sufficient for our needs could adversely affect our business.
Our profitability and results of operations may be adversely affected by new business launch difficulties.
The launch of new business is a complex process, the success of which depends on a wide range of factors, including the production readiness of our manufacturing facilities and manufacturing processes and those of our suppliers, as well as factors related to tooling, equipment, employees, initial product quality and other factors. Our failure to successfully launch new business, or our inability to accurately estimate the cost to design, develop and launch new business, could have an adverse effect on our profitability and results of operations.
To the extent we are not able to successfully launch new business, vehicle production at our customers could be significantly delayed or shut down. Such situations could result in loss of customers, significant financial penalties to us or a diversion of personnel and financial resources to improving launches rather than investment in continuous process improvement or other growth initiatives and could result in our customers shifting work away from us to a competitor, all of which could result in loss of revenue or loss of market share and could have an adverse effect on our profitability and cash flows.
Part of our workforce is unionized, which could subject us to work stoppages.
As of December 31, 2025, approximately 13% of our U.S. workforce was unionized. We have a domestic collective bargaining agreement for one facility in New York, which expires in September 2028. The workforce at certain of our international facilities is also unionized. A prolonged dispute with our employees could have an adverse effect on our business.
Work stoppages, production shutdowns and similar events could significantly disrupt our business.
Because the automotive industry relies heavily on just-in-time delivery of components during the assembly and manufacture of vehicles, a work stoppage or production shutdown at one or more of our manufacturing and assembly facilities could have adverse effects on our business. Similarly, if one or more of our customers were to experience a work stoppage or production shutdown, that customer would likely halt or limit purchases of our products, which could result in the shutdown of the related manufacturing facilities. A significant disruption in the supply of a key component due to supply constraints or due to a work stoppage or production shutdown at one of our suppliers or any other supplier could have the same consequences and, accordingly, have an adverse effect on our financial results.
Our benefit plan expenses and obligations may fluctuate depending on various factors, including changes in interest rates, changes in regulations and plan asset returns.
We have unfunded obligations under certain of our defined benefit pension and other postemployment benefit plans. The valuation of our future payment obligations under the plans and the related plan assets is subject to significant adverse changes if the credit and capital markets cause interest rates and
24

Table of Contents
projected rates of return to decline. Such declines could also require us to make significant additional contributions to our pension plans in the future. Additionally, a material deterioration in the funded status of the plans could significantly increase our pension expenses and reduce profitability in the future.
We also sponsor post-employment medical benefit plans in the U.S. that are unfunded. If medical costs continue to increase or actuarial assumptions are modified, this could have an adverse effect on our business.
We continually monitor changes in global pension regulations as the complexity of pension laws in the jurisdictions where we sponsor plans can present financial risks in the event of noncompliance.
We are subject to extensive environmental regulations that are subject to change and involve significant risks.
Our operations are subject to laws governing, among other things, emissions to air, discharges to waters, and the generation, management, transportation and disposal of waste and other materials. The operation of automotive parts manufacturing plants entails risks in these areas, and we cannot assure that we will not incur material costs or liabilities as a result. Through various acquisitions over the years, we have acquired a number of manufacturing facilities, and we cannot assure that we will not incur material costs and liabilities relating to activities that predate our ownership. In addition, potentially significant expenditures could be required to comply with evolving interpretations of existing environmental, health and safety laws and regulations or any new such laws and regulations (including concerns about global climate change and its impact) that may be adopted in the future. Costs associated with failure to comply with such laws and regulations could have an adverse effect on our business.
Our operations may be affected by greenhouse emissions and climate change and related regulations.
Climate change is receiving increasing attention worldwide, which has led to significant legislative and regulatory efforts to limit greenhouse gas emissions. Our manufacturing plants use energy, including electricity and natural gas, and certain of our plants emit amounts of greenhouse gas that may be affected by these legislative and regulatory efforts. Greenhouse gas regulation could increase the price of the electricity we purchase, increase costs for use of natural gas, potentially restrict access to or the use of natural gas, require us to purchase allowances to offset our own emissions or result in an overall increase in costs of raw materials, any one of which could increase our costs, reduce competitiveness in a global economy or otherwise negatively affect our financial condition, results of operations and reputation. Many of our suppliers face similar circumstances. Supply disruptions would raise market rates and jeopardize the continuity of production and could have an adverse effect on our financial results.
Climate changes could also disrupt our operations by impacting the availability and cost of materials within our supply chain and could also increase insurance and other operating costs. In addition, extreme weather events may damage a facility or surrounding infrastructure, making the facility unusable for a time. These factors may impact our decisions to construct new facilities.

We have been and are exposed to liabilities related to environmental, product warranties, product recalls, litigation and other claims.
We and certain of our current and former direct and indirect corporate predecessors, subsidiaries and divisions have been identified by the United States Environmental Protection Agency and certain state environmental agencies and private parties as potentially responsible parties at various hazardous waste disposal sites under the Comprehensive Environmental Response, Compensation and Liability Act and equivalent state laws, and, as such, may be liable for the cost of clean-up and other remedial activities at such sites. While responsibility for clean-up and other remedial activities at such sites is typically shared among potentially responsible parties based on an allocation formula, we could have greater liability under applicable statutes. Refer to Note 21, “Contingencies,” to the Consolidated Financial Statements in Item 8 of this report for further discussion.
We provide product warranties to our customers for some of our products. Under these product warranties, we may be required to bear costs and expenses for the repair or replacement of these products. As suppliers become more integrally involved in the vehicle design process and assume more of the vehicle assembly functions, auto manufacturers are increasingly looking to their suppliers for contribution when faced with recalls and product warranty claims. A recall claim brought against us, or a product warranty claim brought against us, could adversely impact our results of operations. In addition, a recall claim could require us to review our entire product portfolio to assess whether similar issues are present in other product lines, which could result in significant disruption to our business and could have an adverse impact on our results of operations. We cannot assure that costs and expenses associated with these product warranties will not be material or that those costs will not exceed our available insurance, or any amounts accrued for such product warranties in our financial statements.
We are involved, from time to time, in legal proceedings and commercial or contractual disputes, which could have an adverse impact on our business.
We are involved in legal proceedings and commercial or contractual disputes that, from time to time, are significant. These claims typically arise in the normal course of business and may include, but not be limited to, commercial or contractual disputes with our customers and suppliers, intellectual property matters, personal injury, product liability, tax matters, environmental and employment claims. There is a possibility that such claims may have an adverse impact on our business that is greater than we anticipate. While we maintain insurance for certain risks, the amount of insurance may not be adequate to cover all insured claims and liabilities. The incurrence of significant liabilities for which there is no, or insufficient, insurance coverage could adversely affect our business.
For more information regarding our legal matters, see Item 3. Legal Proceedings of this report.
Compliance with and changes in laws could be costly and could affect our operating results.
We have operations in multiple countries that can be impacted by expected and unexpected changes in the legal and business environments in which we operate. Compliance-related issues in certain countries associated with laws such as the Foreign Corrupt Practices Act and other anti-corruption laws could adversely affect our business. We have internal policies and procedures relating to compliance with such laws; however, there is a risk that such policies and procedures will not always protect us from the improper acts of employees, agents, business partners, joint venture partners, or representatives, particularly in the case of recently acquired operations that may not have significant training in applicable compliance policies and procedures. Violations of these laws, which are complex, may result in criminal penalties, sanctions and/or fines that could have an adverse effect on our business, financial condition, and results of operations and reputation.

Table of Contents
Changes that could impact the legal environment include new legislation, new regulations, new policies, investigations and legal proceedings, and new interpretations of existing legal rules and regulations, in particular, changes in import and export control laws or exchange control laws, additional restrictions on doing business in countries subject to sanctions, additional limitations on greenhouse gas emissions or other matters related to climate change and other changes in laws in countries where we operate or intend to operate.
Changes in tax laws or tax rates by taxing authorities and the outcome of tax audits could adversely affect our business.
Changes in tax laws or tax rates, the resolution of tax assessments or audits by various tax authorities, and the inability to fully utilize our tax loss carryforwards and tax credits could adversely affect our operating results. In addition, we may periodically restructure our legal entity organization, and if taxing authorities were to disagree with our tax positions in connection with any such restructurings, our effective tax rate could be materially affected. On July 4, 2025, the U.S. government enacted tax legislation commonly referred to as the One Big Beautiful Bill Act (the “OBBBA”). The OBBBA made permanent or extended several provisions from the Tax Cuts and Jobs Act of 2017, including the restoration of expensing of domestic research and development expenditures. Future changes to these or other tax laws, as well as related regulations and interpretations, could materially affect our financial statements.
Our tax filings for various periods are subject to audit by the tax authorities in most jurisdictions where we conduct business. We have received tax assessments from various taxing authorities and are currently at varying stages of appeals and/or litigation regarding these matters. These audits may result in assessment of additional taxes that are resolved with the authorities or through the courts. We believe these assessments may occasionally be based on erroneous and even arbitrary interpretations of local tax law. Resolution of tax matters involves uncertainty, and there are no assurances that the outcomes will be favorable.
We are subject to risks related to our international operations.
We have manufacturing and technical facilities in many regions, including Europe, Asia, and the Americas. For 2025, approximately 84% of our consolidated net sales were outside the U.S. We also purchase raw materials and other supplies from many different countries around the world. Consequently, our results could be affected by changes in trade, monetary and fiscal policies, trade restrictions or prohibitions, import or other charges or taxes, fluctuations in foreign currency exchange rates, limitations on the repatriation of funds, data protection regulations, changing economic conditions, unreliable intellectual property protection and legal systems, including the ability to enforce commercial agreements, insufficient infrastructures, social unrest, political instability and disputes, international terrorism and other factors that may be discrete to a particular country or geography. Compliance with multiple and potentially conflicting laws and regulations of various countries is challenging, burdensome and expensive.
The financial statements of foreign subsidiaries are translated to U.S. Dollars using the period-end exchange rate for assets and liabilities and an average exchange rate for each period for sales revenues, expenses and capital expenditures. The local currency is typically the functional currency for our foreign subsidiaries. Significant foreign currency fluctuations and the associated translation of those foreign currencies to U.S. Dollars could adversely affect our business. Additionally, significant changes in currency exchange rates, particularly the Euro, Korean Won and Chinese Renminbi, could cause fluctuations in the reported results of our businesses’ operations that could negatively affect our results of operations.
Because we are a U.S. holding company, one significant source of our funds is distributions from our non-U.S. subsidiaries. Certain countries in which we operate have adopted or could institute currency
27

Table of Contents
exchange controls that limit or prohibit our non-U.S. subsidiaries' ability to convert local currency into U.S. Dollars or to make payments outside the country. This could subject us to the risks of local currency devaluation and business disruption.
Our business in China is subject to aggressive competition and is sensitive to economic, political, and market conditions.
Maintaining a strong position in the Chinese market is a key component of our global growth strategy. The automotive supply market in China is highly competitive, with competition from many of the largest global manufacturers and numerous smaller domestic manufacturers. As the Chinese market evolves, market participants have acted, and we anticipate will continue to act aggressively to increase or maintain their market share. Increased competition may result in price reductions, reduced margins and our inability to gain or hold market share. Domestic Chinese OEMs continue to expand their market share in and outside of China, and are increasingly insourcing certain components once sourced from Tier 1 suppliers. In addition, our business in China is sensitive to economic, political, social and market conditions that drive sales volumes in China. If we are unable to maintain our position in the Chinese market or if vehicle sales in China decrease, our business and financial results could be adversely affected.
For 2025, approximately 21% of our consolidated net sales were attributable to China.
A downgrade in the ratings of our debt could restrict our ability to access the debt capital markets.
Changes in the ratings that rating agencies assign to our debt may ultimately impact our access to the debt capital markets and the costs we incur to borrow funds. If ratings for our debt fall below investment grade, our access to the debt capital markets could become restricted and our cost of borrowing or the interest rate for any subsequently issued debt would likely increase.
Our revolving credit agreement includes an increase in interest rates if the ratings for our debt are downgraded. The interest cost on our revolving credit agreement is based on a rating grid. Further, an increase in the level of our indebtedness and related interest costs may increase our vulnerability to adverse general economic and industry conditions and may affect our ability to obtain additional financing.
Risks related to our customers
We rely on sales to major customers and our supply agreements with them are generally requirements contracts, and a decline in the production requirements of any of our customers, and in particular our major customers could adversely impact our revenues and profitability.
We rely on sales to OEMs around the world of varying credit quality and manufacturing demands. Supply to several of these customers requires significant investment by us. We base our growth projections, in part, on commitments made by our customers. In most instances, our OEM customers agree to purchase their requirements for specific products but are not required to purchase any minimum amount of products from us. These commitments generally renew yearly during a program life cycle. Among other things, the level of production orders we receive is dependent on the ability of our OEM customers to design and sell products that consumers desire to purchase. If actual production orders from our customers do not approximate such commitments due to a variety of factors, including non-renewal of purchase orders, a customer's financial hardship or other unforeseen reasons, it could adversely affect our business.
28

Table of Contents
Some of our sales are concentrated. Our worldwide sales in 2025 to Volkswagen and Ford constituted approximately 13% and 12% of our 2025 consolidated net sales, respectively. Sales to the Company’s top ten customers represented 71% of sales for the year ended December 31, 2025. Changes in our business relationships with any of our major customers or in the timing, size and continuation of their various programs could have a disproportionately material adverse impact on our business. While we continually bid on new business with our existing customers and continually seek to diversify our customer base, our efforts may not be successful. The loss of any of these major customers, the loss of business with respect to one or more of their vehicle models for which we have high component content, or a significant decline in the production levels of such vehicles would negatively impact our business, results of operations and financial condition.
We are sensitive to the effects of our major customers’ labor relations.
All three of our primary North American customers, Ford, Stellantis, and General Motors, have major union contracts with the International Union, United Automobile, Aerospace and Agricultural Implement Workers of America (or “UAW”). Because of domestic OEMs’ dependence on a single union, we are affected by labor difficulties and work stoppages at OEMs’ facilities, such as the UAW strikes that occurred in 2023. Such stoppages at OEMs’ facilities could halt our businesses with those facilities, and an increase in the number of OEMs facilities with union contracts with the UAW could increase the negative impact to our business. Similarly, a majority of our global customers’ operations outside of North America are also represented by various unions. Any extended work stoppage at one or more of our customers could delay the manufacture and sale of our products and have an adverse effect on our business and operating results.
Risks related to our suppliers
We could be adversely affected by supply shortages of components from our suppliers.
In an effort to manage and reduce the cost of purchased goods and services, we have been rationalizing our supply base. As a result, we remain dependent on fewer sources of supply for certain components used in the manufacture of our products. We select suppliers based on total value (including total landed price, quality, delivery, and technology), taking into consideration their production capacities and financial condition. We expect that they will deliver to our stated written expectations.
However, there can be no assurance that capacity limitations, industry shortages, labor or social unrest, weather emergencies, commercial disputes, government actions, riots, wars, sabotage, cyber-attacks, non-conforming parts, acts of terrorism, “Acts of God,” or other problems that our suppliers experience will not result in shortages or delays in their supply of components to us. If we experience a prolonged shortage of critical components from any of our suppliers and cannot procure the components from other sources, we may be unable to meet the production schedules for some of our key products and could miss customer delivery expectations. In addition, with fewer sources of supply for certain components, each supplier may perceive that it has greater leverage and, therefore, some ability to seek higher prices from us at a time that we face substantial pressure from OEMs to reduce the prices of our products, which could adversely affect our customer relations and business.
29

Table of Contents
Suppliers’ economic distress could result in supply interruptions and, in turn, disrupt our operations and adversely affect our business.
Rapidly changing industry conditions such as volatile production volumes, including volatility in electric vehicle adoption across different regions; our need to seek price reductions from our suppliers as a result of the substantial pressure we face from OEMs to reduce the prices of our products; credit tightness; changes in foreign currency exchange rates; raw material, commodity, tariffs, transportation, and energy price escalation; drastic changes in consumer preferences; and other factors could adversely affect our supply chain, and sometimes with little advance notice. These conditions could also result in increased commercial disputes and supply interruption risks. In certain instances, it would be difficult and expensive for us to change suppliers that are critical to our business. On occasion, we must provide financial support to distressed suppliers or take other measures to protect our supply lines. We cannot predict with certainty the potential adverse effects these costs might have on our business and results of operations.
We are subject to possible insolvency of financial counterparties.
We engage in numerous financial transactions and contracts, including insurance policies, letters of credit, credit line agreements, financial derivatives, and investment management agreements involving various counterparties. We are subject to the risk that one or more of these counterparties may become insolvent and, therefore, be unable to meet its obligations under such contracts.
Risks related to the spin-off of PHINIA Inc.
The spin-off of PHINIA may not achieve anticipated tax benefits and may expose us to additional tax risks.
We may not realize the anticipated tax benefits of the spin-off of PHINIA. While it is intended that the transaction was tax-free to the Company’s stockholders for U.S. federal income tax purposes, there is no assurance that the transaction will qualify for this treatment. If the spin-off is ultimately determined to be taxable, the Company, PHINIA, or the Company’s stockholders could incur income tax liabilities that could be significant. If we do not realize the anticipated tax benefits of the spin-off, it could adversely affect our business, results of operations, cash flows and financial condition.
Potential liabilities pursuant to the spin-off of PHINIA could materially and adversely affect our business.
In connection with the spin-off, we entered into a separation and distribution agreement and related agreements with PHINIA to govern the spin-off and the relationship between the two companies following the completion of the spin-off. These agreements provide for specific indemnity and liability obligations of each party and have led, and could in the future lead, to disputes between us. For example, on September 19, 2024, we commenced a lawsuit against PHINIA, seeking to recover from PHINIA approximately $120 million of value added tax (“VAT”) refunds that PHINIA received or expects to receive from governmental agencies as well as damages and interest. These refunds consisted of VAT paid by the Company in periods prior to or directly related to the spin-off that established PHINIA as an independent company. PHINIA responded to the lawsuit and also asserted counterclaims against the Company. On October 15, 2025, the Company entered into a settlement agreement (the “Settlement Agreement”) with PHINIA, pursuant to which PHINIA agreed to pay the Company $78 million, resolving the lawsuit and certain other matters relating to the spin-off. In connection with the Settlement Agreement, the Company and PHINIA also entered into an amended and restated tax matters agreement that, among other things, limits the Company’s responsibility to certain defined tax obligations. As a result, the Company recorded a net charge of $40 million as of December 31, 2025, for the reduction of VAT-related receivables, the elimination of certain Company liabilities under the amended and restated tax matters agreement and related legal fees, which is included in Other operating expense, net in the Company’s

Consolidated Statements of Operations in Item 8 of this report. If we are required to indemnify PHINIA and other parties under the circumstances set forth in the agreements with PHINIA, we may be subject to future liabilities. In addition, with respect to the liabilities for which PHINIA and the other parties have agreed to indemnify us under these agreements, the indemnity rights we have against PHINIA and such other parties may not be sufficient to protect us against the full amount of the liabilities, further PHINIA or such other parties may not be able to fully satisfy their indemnification obligations. It is also possible that a court could disregard the allocation of assets and liabilities agreed to among the Company, PHINIA and such other parties and require the Company to assume responsibility for obligations allocated to PHINIA or such other parties or to cause the Company to not realize an asset on its Consolidated Balance Sheet. Any of these outcomes could result in additional costs, reduce the value of our assets or otherwise negatively affect our business and financial results.
Other risks
A variety of other factors could adversely affect our business.
Any of the following could materially and adversely affect our business and results of operations: the loss of or changes in supply contracts or sourcing strategies of our major customers or suppliers; start-up expenses associated with new vehicle programs or delays or cancellation of such programs; low levels of utilization of our manufacturing facilities, which can be dependent on a single product line or customer; inability to recover engineering and tooling costs; market and financial consequences of recalls that may be required on products we supplied; delays or difficulties in new product development; the possible introduction of similar or superior technologies by others; global excess capacity and vehicle platform proliferation; and the impact of fire, flood, or other natural disasters, including pandemics and quarantines.
Item 1B. Unresolved Staff Comments
The Company has received no written comments regarding its periodic or current reports from the staff of the Securities and Exchange Commission that were issued 180 days or more preceding the end of its 2025 fiscal year that remain unresolved.
Item 1C. Cybersecurity
BorgWarner’s Board of Directors acknowledges the importance of upholding the trust and confidence of BorgWarner’s customers, business partners, employees and other stakeholders. The Board, in conjunction with the Audit Committee, is involved in the oversight of the Company’s risk management program, including its Cybersecurity Program. The Cybersecurity Program is managed by the Chief Information Officer (“CIO”), whose information technology (“IT”) team is responsible for enterprise-wide IT, including cybersecurity strategy, policy, standards, architecture and processes. The Company benchmarks the Cybersecurity Program, including its standards, processes and practices, against recognized cybersecurity frameworks. The Cybersecurity Program continually enhances the enterprise security structure and contingency plans with the goal of preventing cybersecurity incidents to the extent feasible and minimizing the business impact should an incident occur.
Risk Management and Strategy
Collaborative Approach: The Company has implemented a comprehensive, cross-functional approach to identifying, preventing and mitigating cybersecurity threats and incidents. The Cybersecurity Program has various tools and programs in place to monitor and address potential threats and incidents impacting the Company’s operations and to determine the materiality of and ensure timely public disclosure of such threat or incident, if appropriate.
31

Table of Contents
Technical Safeguards: The Company deploys technical safeguards designed to protect the Company’s information systems from cybersecurity threats. The Company deploys tools in an effort to detect vulnerabilities, and when a weakness is identified, the Company seeks to assess the significance of the impact and mitigate before the weakness is exploited by an unauthorized actor.
Incident Response and Recovery Plan: The Company has an incident response and recovery plan, which details the steps to be taken from the initial internal reporting of a potential cybersecurity incident.
Third-Party Risk Management: The Company continues to review processes and procedures that identify and oversee cybersecurity risks presented by third parties, including service providers, vendors and other users of the Company’s systems. In December 2024, the Company updated its indirect Purchase Order Terms and Conditions, effective January 1, 2025, to address (i) supplier cybersecurity incident notification requirements and (ii) the Company’s right to audit supplier IT systems.
Education and Awareness: The Company provides regular, mandatory training for applicable personnel on cybersecurity threats to help them identify, avoid and address cybersecurity threats and to communicate the Cybersecurity Program, including applicable policies, standards, processes and practices.
Governance
The Board and the Audit Committee actively discuss cybersecurity risks with management and among themselves. The CIO annually reports on the Cybersecurity Program and the Company’s approach to cybersecurity risk management to the Audit Committee of the Board of Directors and to the full Board periodically, as appropriate. These reports include updates on the Company’s cybersecurity risks and threats, the status of projects to strengthen the Company’s information security systems, assessments of the Cybersecurity Program, recent developments, evolving standards and emerging threats or trends within cybersecurity. The Audit Committee and Board receive prompt and timely information regarding cybersecurity threats and incidents that meet specified thresholds, as well as ongoing updates regarding any such threats or incidents until they have been addressed.
The Cybersecurity Program is managed by the CIO, and the Company’s IT team is responsible for enterprise-wide informational technology, coordinating with various functions and business groups to ensure they are following best practices. The current CIO has over two decades of experience in various roles in IT and information security. The CIO and the IT team work with the business to implement the Cybersecurity Program, which is designed to protect the Company’s information systems from cybersecurity threats and to promptly respond to any cybersecurity incidents in accordance with the Company’s Cybersecurity Incident Response Plan. The CIO and the IT team use detection tools to monitor for cybersecurity threats and incidents in real time, apply mitigation and remediation steps and then report such threats to the Audit Committee and the Board, as appropriate.
The Company’s efforts include a wide range of actions, including audits, assessments, tabletop exercises, threat modeling, vulnerability testing and other exercises focused on evaluating and improving the effectiveness of the Company’s cybersecurity measures and planning. The Company engages in periodic assessment and testing of the Cybersecurity Program and may periodically engage a third-party expert to conduct assessments, audits and testing. The results of such assessments, audits and testing are reported to the CIO and the Audit Committee or full Board, as applicable, and the Company makes adjustments as appropriate.
As of the date of this report, the Company is not aware of any material risks from cybersecurity threats that have materially affected or are reasonably likely to materially affect the Company, including its business strategy, results of operations, or financial condition. Despite the extensive approach we take to cybersecurity, we may not be successful in preventing or mitigating a cybersecurity incident that could

Purchase of Equity Securities
In April 2024, the Company’s Board of Directors authorized the purchase of up to $767 million of the Company’s common stock, which replaced the previous repurchase authorization. By its terms, this share repurchase authorization was scheduled to expire on December 31, 2027. As of June 30, 2025, the Company had purchased $408 million of common stock under this repurchase authorization, excluding any related fees and taxes, including $108 million purchased during the six month ended June 30, 2025. In July 2025, the Company’s Board of Directors authorized the purchase of up to $1 billion of the Company’s common stock, which replaced the previous authorization. By its terms, this share repurchase authorization expires on December 31, 2028. As of December 31, 2025, the Company had repurchased $400 million of common stock under this authorization, excluding any related fees and taxes. Shares purchased under this authorization may be repurchased in the open market at prevailing prices and at times and in amounts to be determined by management based on the Company's capital position. The Company may use Rule 10b5-1 and 10b-18 plans to facilitate share repurchases. Repurchased shares will be deemed common stock held in treasury and may subsequently be reissued.
Employee transactions include restricted stock withheld to offset statutory minimum tax withholding that occurs upon vesting of restricted stock. The BorgWarner Inc. 2023 Stock Incentive Plan provides that the withholding obligations be settled by the Company retaining stock that is part of the award.

manufacturers (“OEMs”) of light vehicles (passenger cars, sport-utility vehicles, vans and light trucks). The Company’s products are also sold to OEMs of commercial vehicles (medium-duty trucks, heavy-duty trucks and buses) and off-highway vehicles (agricultural and construction machinery and marine applications). The Company also manufactures and sells its products to certain tier one vehicle systems suppliers and into the aftermarket for light, commercial and off-highway vehicles. The Company operates manufacturing facilities serving customers in Europe, the Americas and Asia and is an original equipment supplier to nearly every major automotive OEM in the world.
BorgWarner Strategy
The Company’s current strategy is to focus on profitable growth across its technology-focused product portfolio that supports electric, hybrid and combustion vehicles. This entails growing its product portfolio through organic investments and technology-focused acquisitions. The Company’s balanced portfolio is particularly critical as the automotive industry continues to see electric vehicle adoption volatility across different regions. During the years ended December 31, 2025, 2024 and 2023, the Company’s revenue from eProducts, which include all products utilized on or for electric vehicles (“EVs”) plus those same products and components that are included in hybrid powertrains whose underlying technologies are adaptable or applicable to those used in or for EVs, was approximately $2.6 billion, $2.3 billion and $2.0 billion, respectively, or 18%, 17% and 14% of its total revenue, respectively, and the Company’s revenue from Foundational products, which include all products utilized on internal combustion engines plus those same products and components that are also included in hybrid powertrains, was approximately $11.7 billion, $11.8 billion and $12.2 billion, respectively, or 82%, 83% and 86% of its total revenue, respectively.
Lawsuit Against PHINIA
On September 19, 2024, the Company commenced a lawsuit against PHINIA, seeking to recover from PHINIA approximately $120 million of value added tax (“VAT”) refunds that PHINIA received or expects to receive from governmental agencies as well as damages and interest. These refunds consisted of VAT paid by the Company in periods prior to or directly related to the spin-off that established PHINIA as an independent company. PHINIA responded to the lawsuit and also asserted counterclaims against the Company. On October 15, 2025, the Company entered into a settlement agreement (the “Settlement Agreement”) with PHINIA, pursuant to which PHINIA agreed to pay the Company $78 million, resolving the lawsuit and certain other matters relating to the spin-off. In connection with the Settlement Agreement, the Company and PHINIA also entered into an amended and restated tax matters agreement that, among other things, limits the Company’s responsibility to certain defined tax obligations. As a result, the Company recorded a net charge of $40 million during the year ended December 31, 2025, for the reduction of VAT-related receivables, the elimination of certain Company liabilities under the amended and restated tax matters agreement and related legal fees, which is included in Other operating expense, net in the Company’s Consolidated Statements of Operations. As of December 31, 2025, after giving effect to the Settlement Agreement and the $31 million payment received during the fourth quarter of 2025, the Company had assets related to these VAT refunds of approximately $47 million included in Receivables, net in the Company’s Consolidated Balance Sheet in Item 8 of this report.

Portfolio Actions
In February 2025, the Company made the decision to exit its charging business within the Battery & Charging Systems reportable segment. Production operations ceased during the second quarter of 2025. This decision was made following the Company’s continuing evaluation of its product portfolio and future investments. This action was intended to create a more focused portfolio and is expected to eliminate approximately $30 million of annualized adjusted operating losses by 2026. Refer to Note 2, “Acquisitions and Dispositions,” to the Consolidated Financial Statements in Item 8 of this report for more information.
The Company also made the decision to consolidate its North American battery systems business, which is expected to align the business’ cost structure to current market dynamics. This action is expected to result in annual cost savings of approximately $20 million by 2026.
North Carolina Facility Hurricane
On September 26, 2024, a hurricane made landfall in North Carolina disrupting operations at the Company’s facility in Arden, North Carolina (the “Arden Plant”). The Arden Plant was largely untouched, but the Company experienced some loss or damage to the Company’s assets amounting to less than $10 million. The Arden plant resumed full operations during the fourth quarter of 2024. The Company’s insurance policies (less applicable deductibles) covered the repair or replacement of the Company’s assets that incurred loss or damage and provided coverage for interruption to its business, including lost profits, and reimbursement for other expenses and costs that were incurred related to the damages and losses sustained. For the year ended December 31, 2025, the Company recorded committed insurance recoveries of approximately $9 million, which are included as a reduction of Cost of sales in the Company’s Consolidated Statements of Operations in Item 8 of this report and were fully collected.
Acquisitions and Dispositions
Acquisitions have been an integral component of the Company’s growth and value creation strategy. Refer to Note 2, “Acquisitions and Dispositions,” to the Consolidated Financial Statements in Item 8 of this report for more information, including a summary of recent acquisitions.
Key Trends and Economic Factors
Economic Conditions. The Company’s financial performance depends on conditions in the global automotive industry. Automotive and truck production and sales are cyclical and sensitive to general economic conditions and other factors, including interest rates, consumer credit and consumer spending and preferences. Government policies, such as the imposition of, termination of or other changes in tariffs (including retaliatory tariffs), or the commencement or termination of consumer tax incentives, such as EV tax credits and programs to invest in infrastructure, including EV charging stations, may affect consumer preferences. Economic declines or impacts of tariffs that result in a material reduction in automotive or truck production would have an adverse effect on the Company’s sales. The weighted average market production, as estimated by the Company for the year ended December 31, 2025, was approximately flat from the year ended December 31, 2024. Weighted average market production reflects light and commercial vehicle production as reported by S&P Global, weighted for the Company’s geographic exposure, as estimated by the Company.
Commodities and Other Inflationary Impacts. During 2025, prices for commodities showed a lower level of volatility in comparison to what the Company had experienced from the beginning of 2021. The Company expects commodities and other costs to be relatively flat in 2026. However, the Company has experienced impacts from commodity pricing, inflation and tariffs over the last several years. Volatility in these areas and other factors could cause actual costs to be materially higher than expected in 2026.

Outlook
The Company expects global industry production to be flat to down modestly year-over-year in 2026. The Company expects a negative sales impact from declining sales in the Company’s Battery & Charging Systems segment. As a result, at the mid-point of its outlook, the Company expects total sales in 2026 to decline year-over-year, excluding the impact of foreign currencies.
The Company maintains a positive long-term outlook for its global business and is committed to new product development and strategic investments to enhance its product leadership strategy. There are several trends that are driving the Company’s long-term growth that management expects to continue, including adoption of product offerings for electrified vehicles and increasingly stringent global emissions standards that support demand for the Company’s products that drive vehicle efficiency.

Turbos & Thermal Technologies net sales for the year ended December 31, 2025 decreased $115 million, or 2%, and Segment Adjusted Operating Income increased $2 million from the year ended December 31, 2024. The sales decrease was primarily due to volume of approximately $192 million driven by lower volumes in Europe, partially offset by higher volumes in the Americas and aftermarket. These decreases were partially offset by the impact of foreign currencies, which resulted in a year-over-year increase in sales of approximately $77 million, primarily due to the strengthening of the Euro and British Pound, partially offset by the weakening of the Brazilian Real and Korean Won, in each case relative to the U.S. Dollar. Segment Adjusted Operating margin was 15.2% for the year ended December 31, 2025, compared to 14.9% in the year ended December 31, 2024. The Segment Adjusted Operating margin increase was primarily due to supply chain savings, manufacturing efficiencies and restructuring savings, partially offset by decremental conversion on lower sales.
Drivetrain & Morse Systems net sales for the year ended December 31, 2025 increased $77 million, or 1%, and Segment Adjusted Operating Income increased $31 million from the year ended December 31, 2024. Foreign currencies resulted in a year-over-year increase in sales of approximately $42 million, primarily due to the strengthening of the Euro and Thai Baht, partially offset by the weakening of the Korean Won, in each case relative to the U.S. Dollar. The increase was also due to approximately $35 million of volume, mix and net new business driven by higher transfer case volumes in the Americas, partially offset by lower sales in China and downtime at one of the Company’s European customers due to a cyber related shutdown. Segment Adjusted Operating margin was 18.4% in the year ended December 31, 2025, compared to 18.1% in the year ended December 31, 2024. The Segment Adjusted Operating margin increase was primarily due to incremental conversion on higher sales, supply chain savings and manufacturing efficiencies.

PowerDrive Systems net sales for the year ended December 31, 2025 increased $410 million, or 21%, and Segment Adjusted Operating Loss decreased $61 million from the year ended December 31, 2024. The sales increase was primarily due to approximately $388 million of volume, mix and net new business driven by eProducts growth in China and Europe. Foreign currencies also resulted in a year-over-year increase in sales of approximately $22 million, primarily due to the strengthening of the Euro, partially offset by the weakening of the Korean Won, in each case relative to the U.S. Dollar. Segment Adjusted Operating margin was (3.5)% in the year ended December 31, 2025, compared to (7.4)% in the year ended December 31, 2024. The increase in Segment Adjusted Operating margin was primarily due to incremental conversion on higher sales, customer volume recoveries and supply chain and restructuring savings.
Battery & Charging Systems net sales for the year ended December 31, 2025 decreased $139 million, or 19%, and Segment Adjusted Operating Loss decreased $8 million from the year ended December 31, 2024. The sales decrease was primarily due to approximately $65 million of lower volume, mix and net new business primarily due to lower battery back volumes. Additionally, sales decreased approximately $56 million related to the exit of the charging business. Finally, a decrease in normal contractual customer commodity pass-through arrangements decreased net sales by $31 million. These decreases were partially offset by the impact of foreign currencies, which resulted in a year-over-year increase in sales of approximately $13 million, primarily due to the strengthening in the Euro relative to the U.S. Dollar. Segment Adjusted Operating margin was (6.6)% in the year ended December 31, 2025, compared to (6.4)% in the year ended December 31, 2024. The decrease in the Segment Adjusted Operating margin was primarily due to lower sales and higher depreciation costs, offset by restructuring savings, customer recoveries and other operational improvements.

Contractual Obligations
The Company’s significant cash requirements for contractual obligations as of December 31, 2025 primarily consisted of the principal and interest payments on its notes payable and long-term debt, non-cancelable financing lease obligations, capital spending obligations and purchase obligations. The principal amount of notes payable due within the next twelve months was $5 million and long-term debt was $3,925 million, excluding the impact of unamortized premiums and discounts of approximately $31 million, as of December 31, 2025. The projected interest payments over the terms of that debt due within the next twelve months and beyond were $109 million and $805 million, respectively, as of December 31, 2025. Refer to Note 14, “Debt,” to the Consolidated Financial Statements in Item 8 of this report for more information.
As of December 31, 2025, non-cancelable operating lease obligations due within twelve months and beyond were $39 million and $165 million, respectively. Refer to Note 22, “Leases and Commitments,” to the Consolidated Financial Statements in Item 8 of this report for more information. Capital spending obligations due within the next twelve months were $116 million as of December 31, 2025.
The Company enters into agreements with its suppliers to assist in meeting its customers’ production needs. These agreements vary as to duration and terms, and historically, most do not provide for minimum purchases by the Company, or they are requirements-based arrangements. However, as of December 31, 2025, the Company had contractual purchase commitments of approximately $180 million for certain electronics components to be paid through 2027.
Management believes that the combination of cash from operations, cash balances, available credit facilities, and the universal shelf registration capacity will be sufficient to satisfy the Company’s cash needs for its current level of operations and its planned operations for the foreseeable future. Management will continue to balance the Company’s needs for organic growth, inorganic growth, debt reduction, cash conservation and return of cash to shareholders.
Postretirement Defined Benefits
The Company’s policy is to fund its defined benefit pension plans in accordance with applicable government regulations and to make additional contributions when appropriate. At December 31, 2025, all legal funding requirements had been met. The Company contributed $23 million, $39 million and $21 million to its defined benefit pension plans in the years ended December 31, 2025, 2024 and 2023, respectively.
The Company expects to contribute approximately $25 million into its defined benefit pension plans during 2026. Of the $25 million in projected 2026 contributions, $8 million are contractually obligated, while any remaining payments would be discretionary.
The funded status of all pension plans was a net unfunded position of $36 million and $66 million at December 31, 2025 and 2024, respectively. The decrease in the net unfunded position was a result of a higher pension assets, which was primarily due to asset returns during the period and the impact of foreign exchange. Of the total net unfunded amounts, $17 million and $32 million at December 31, 2025 and 2024, respectively, were related to plans in Germany, where there is no tax deduction allowed under the applicable regulations to fund the plans; hence, the common practice is to make contributions as benefit payments become due.
Other postemployment benefits primarily consist of health care benefits for certain former employees and retirees of the Company’s U.S. operations. The Company funds these benefits as retiree claims are incurred. Other postemployment benefits had an unfunded status of $27 million and $29 million at December 31, 2025 and 2024, respectively.

In August 2025, the Company executed an amendment to the plan document of one of the Company’s U.S. defined benefit pension plans (“U.S. Pension Plan”) to terminate the plan effective October 31, 2025. The termination of the U.S. Pension Plan is expected to take up to eighteen months to complete. As part of the termination process, the Company expects to settle benefit obligations under the U.S. Pension Plan through a combination of lump sum payments to eligible plan participants and the purchase of a group annuity contract under which future benefit obligations and administration will be transferred to a third-party insurance company. Such settlements will be funded primarily from plan assets. At December 31, 2025, the U.S. Pension Plan’s projected benefit obligation exceeded the fair value of the assets by $4 million under U.S. GAAP.
In December 2024, the Company entered into a second buy-in contract (the first buy-in contract was entered into in 2019) with an insurance company related to its U.K. pension plan. Pursuant to this agreement, the Company liquidated approximately $50 million of pension plan assets to invest in an insurance annuity. At December 31, 2025, the U.K. pension plan had plan assets of $131 million, all held by the insurance company. The projected benefit obligation of the U.K. pension plan at December 31, 2025 was $104 million under U.S. GAAP. The U.K. pension plan was overfunded by $27 million as of December 31, 2025, under U.S. GAAP.
The Company believes it will be able to fund the requirements of these plans through cash generated from operations or other available sources of financing for the foreseeable future.
Refer to Note 18, “Retirement Benefit Plans,” to the Consolidated Financial Statements in Item 8 of this report for more information regarding costs and assumptions for employee retirement benefits.
OTHER MATTERS
Contingencies
In the normal course of business, the Company is party to various commercial and legal claims, actions and complaints, including matters involving warranty claims, intellectual property claims, governmental investigations and related proceedings, general liability and other risks. It is not possible to predict with certainty whether or not the Company will ultimately be successful in any of these commercial and legal matters or what the impact might be. The Company does not believe that adverse outcomes in any of these commercial and legal claims, actions and complaints are reasonably likely to have a material adverse effect on the Company’s results of operations, financial position or cash flows. An adverse outcome could, nonetheless, be material to the results of operations or cash flows as the ultimate resolutions of these matters are inherently unpredictable.

Lawsuit Against PHINIA
On September 19, 2024, the Company commenced a lawsuit against PHINIA, seeking to recover from PHINIA approximately $120 million of VAT refunds that PHINIA received or expects to receive from governmental agencies as well as damages and interest. These refunds consisted of VAT paid by the Company in periods prior to or directly related to the Spin-Off that established PHINIA as an independent company. PHINIA responded to the lawsuit and also asserted counterclaims against the Company. On October 15, 2025, the Company entered into the Settlement Agreement with PHINIA, pursuant to which PHINIA agreed to pay the Company $78 million, resolving the lawsuit and certain other matters relating to the Spin-Off. In connection with the Settlement Agreement, the Company and PHINIA also entered into an amended and restated tax matters agreement that, among other things, limits the Company’s responsibility to certain defined tax obligations. As a result, the Company recorded a net charge of $40 million during the year ended December 31, 2025, for the reduction of VAT-related receivables, the elimination of certain Company liabilities under the amended and restated tax matters agreement and related legal fees, which is included in Other operating expense, net in the Company’s Consolidated Statements of Operations. As of December 31, 2025, after giving effect to the Settlement Agreement and the $31 million payment received during the fourth quarter of 2025, the Company had assets related to these VAT refunds of approximately $47 million included in Receivables, net on the Company’s Consolidated Balance Sheet.
Environmental
The Company and certain of its current and former direct and indirect corporate predecessors, subsidiaries and divisions have been identified by the United States Environmental Protection Agency and certain state environmental agencies and private parties as potentially responsible parties (“PRPs”) at various hazardous waste disposal sites under the Comprehensive Environmental Response, Compensation and Liability Act (“Superfund”) and equivalent state or local laws and, as such, may have been liable for the cost of clean-up and other remedial activities at 16 and 17 such sites as of December 31, 2025 and 2024, respectively. Responsibility for clean-up and other remedial activities at a Superfund site is typically shared among PRPs based on an allocation formula.
The Company believes that none of these matters, individually or in the aggregate, will have a material adverse effect on its results of operations, financial position or cash flows. Generally, this is because either the estimates of the maximum potential liability at a site are not material or the liability will be shared with other PRPs, although no assurance can be given with respect to the ultimate outcome of any such matter.
Refer to Note 21, “Contingencies,” to the Consolidated Financial Statements in Item 8 of this report for further details and information respecting the Company’s environmental liability.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
The consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States (“GAAP”). In preparing these financial statements, management has made its best estimates and judgments of certain amounts included in the financial statements, giving due consideration to materiality. Critical accounting policies are those that are most important to the portrayal of the Company’s financial condition and results of operations. Some of these policies require management's most difficult, subjective or complex judgments in the preparation of the financial statements and accompanying notes. Management makes estimates and assumptions about the effect of matters that are inherently uncertain, relating to the reporting of assets, liabilities, revenues, expenses and the disclosure of contingent assets and liabilities. The Company’s most critical accounting policies are discussed below.
53

Table of Contents
Business combinations The Company allocates the cost of an acquired business to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The excess value of the cost of an acquired business over the estimated fair value of the assets acquired and liabilities assumed is recognized as goodwill. The valuation of the acquired assets and liabilities will impact the determination of future operating results. The Company uses a variety of information sources to determine the value of acquired assets and liabilities, including third-party appraisers for the values and lives of property, identifiable intangibles and inventories, and actuaries for defined benefit retirement plans. Goodwill is assigned to reporting units as of the date of the related acquisition. If goodwill is assigned to more than one reporting unit, the Company utilizes a method that is consistent with the manner in which the amount of goodwill in a business combination is determined. Costs related to the acquisition of a business are expensed as incurred.
Acquired intangible assets include customer relationships, developed technology and trade names. The Company estimates the fair value of acquired intangible assets using various valuation techniques. The primary valuation techniques used include forms of the income approach, specifically the relief-from-royalty and multi-period excess earnings valuation methods. Under these valuation approaches, the Company is required to make estimates and assumptions from a market participant perspective, which may include revenue growth rates, estimated earnings, royalty rates, obsolescence factors, contributory asset charges, customer attrition and discount rates. Under the multi-period excess earnings method, value is estimated as the present value of the benefits anticipated from ownership of the asset, in excess of the returns required on the investment in contributory assets that are necessary to realize those benefits. The intangible asset’s estimated earnings are determined as the residual earnings after quantifying estimated earnings from contributory assets. When the Company estimates fair value using the relief-from-royalty method, it calculates the cost savings associated with owning rather than licensing the assets. Assumed royalty rates are applied to projected revenue for the remaining useful lives of the assets to estimate the royalty savings.
While the Company uses its best estimates and assumptions, fair value estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Any adjustments required after the measurement period are recorded in the consolidated statement of earnings.
Future changes in the judgments, assumptions and estimates that are used in acquisition valuations and intangible asset and goodwill impairment testing, including discount rates or future operating results and related cash flow projections, could result in significantly different estimates of the fair values in the future. An increase in discount rates, a reduction in projected cash flows or a combination of the two could lead to a reduction in the estimated fair values, which may result in impairment charges that could materially affect the Company’s financial statements in any given year.
Impairment of long-lived assets, including definite-lived intangible assets The Company reviews the carrying value of its long-lived assets, whether held for use or disposal, including other amortizing intangible assets, when events and circumstances warrant such a review under Accounting Standards Codification (“ASC”) Topic 360. In assessing long-lived assets for an impairment loss, assets are grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. In assessing long-lived assets for impairment, management generally considers individual facilities to be the lowest level for which identifiable cash flows are largely independent. A recoverability review is performed using the undiscounted cash flows if there is a triggering event. If the undiscounted cash flow test for recoverability identifies a possible impairment, management will perform a fair value analysis. Management determines fair value under ASC Topic 820 using the appropriate valuation technique of market, income or cost approach. If the carrying value of a long-lived asset is considered impaired, an impairment charge is
54

Table of Contents
recorded for the amount by which the carrying value of the long-lived asset exceeds its fair value, calculated based on independent appraisals, discounted cash flows, estimated salvage value, or estimated orderly liquidation value, giving consideration to the highest and best use of the relevant assets.
Management believes that the estimates of future cash flows and fair value assumptions are reasonable; however, changes in assumptions underlying these estimates could affect the valuations. Significant judgments and estimates used by management when evaluating long-lived assets for impairment include (i) an assessment as to whether an adverse event or circumstance has triggered the need for an impairment review; (ii) undiscounted future cash flows generated by the asset; and (iii) fair valuation of the asset. Events and conditions that could result in impairment in the value of long-lived assets include changes in the industries in which the Company operates, particularly the impact of a downturn in the global economy, as well as competition and advances in technology, adverse changes in the regulatory environment, or other factors leading to reduction in expected long-term sales or profitability.
Goodwill and other indefinite-lived intangible assets During the fourth quarter of each year, the Company tests goodwill for impairment by either performing a qualitative assessment or a quantitative analysis. In addition, the Company may test goodwill in between annual test dates if an event occurs or circumstances change that could indicate it is more-likely-than-not that the fair value of a reporting unit is below its carrying value.
The qualitative assessment evaluates various events and circumstances, such as macroeconomic conditions, industry and market conditions, cost factors, relevant events and financial trends, that may impact a reporting unit's fair value. Using this qualitative assessment, the Company determines whether it is more-likely-than-not the reporting unit's fair value exceeds its carrying value. If it is determined that it is not more-likely-than-not the reporting unit's fair value exceeds the carrying value, or upon consideration of other factors, including recent acquisition, restructuring or disposal activity or to refresh the fair values, the Company performs a quantitative goodwill impairment analysis.
During the first quarter of 2025, as a result of the Company’s plan to exit the charging business, the Company separately allocated the goodwill from its historical reporting unit of Battery & Charging Systems to the battery systems business and to the charging business on a relative fair value basis. The Company estimated the allocated fair values of the businesses from the historical reporting unit based upon the present value of their anticipated future cash flows. The estimated fair value of the charging business was determined using a cost approach. The Company’s determination of fair value involved judgment and the use of estimates and assumptions. During the first quarter, the relative fair value analysis resulted in an allocation, and subsequent impairment, of $13 million related to the goodwill allocated to the charging business. Refer to Note 2, “Acquisitions and Dispositions,” to the Consolidated Financial Statements in Item 8 of this report for more information.
In conjunction with the goodwill allocation in the first quarter of 2025, the Company performed a quantitative impairment assessment of the Battery & Charging Systems’ goodwill after the impairment of the charging business’ goodwill. Based on the interim impairment test in the first quarter of 2025, the Battery & Charging Systems reporting unit had an estimated fair value that exceeded its carrying value, including goodwill, by approximately 18%, resulting in no impairment at that time.

During the fourth quarter of 2025, the Company performed a qualitative analysis on its Turbos & Thermal Technologies and Drivetrain & Morse Systems reporting units and performed a quantitative analysis on its Battery & Charging Systems reporting unit. The goodwill associated with the Company’s PowerDrive Systems reporting unit was fully impaired during the year ended December 31, 2024. The Company’s qualitative assessment indicated it was more-likely-than-not that the fair value of the Turbos & Thermal Technologies and Drivetrain & Morse Systems reporting units exceeded their carrying values. For the quantitative analysis, the estimated fair values were determined using an income approach. Under the income approach, fair value is determined based on present value of estimated future cash flows, discounted at an appropriate risk-adjusted rate. The Company used internal forecasts to estimate future cash flows and included an estimate of long-term future growth rates based on the Company’s most recent views of the long-term outlook for its business.
For the reporting unit for which the Company performed a quantitative analysis, the Company believes the assumptions and estimates used to determine the estimated fair value are reasonable. Different assumptions could materially affect the estimated fair value. The significant assumptions affecting the Company’s 2025 goodwill quantitative impairment review were as follows:
•Discount rates: The Company used a 14% weighted average cost of capital (“WACC”) as the discount rates for future cash flows. The WACC is intended to represent a rate of return that would be expected by a market participant.
•Operating income (loss) margin: The Company used historical and expected operating income (loss) margins, which may vary based on the projection of the reporting unit being evaluated.
•Revenue growth rates: The Company used a global automotive market industry growth rate forecast adjusted to estimate its own market participation for product lines.
In addition to the above significant assumptions, the Company noted the following risks to volume and operating income assumptions that could have an impact on the discounted cash flow models:
•The automotive industry is cyclical, and the Company’s results of operations could be adversely affected by industry downturns.
•The automotive industry is evolving, and if the Company does not respond appropriately, its results of operations could be adversely affected.
•The Company is dependent on market segments that use its key products and could be affected by decreasing demand in those segments.
•The Company is subject to risks related to international operations.
During the fourth quarter of 2025, in connection with the preparation of the Company’s annual financial statements, the Company noted deterioration in the forecast for its Battery & Charging Systems business. This deterioration was due to dual sourcing actions by certain customers, pricing pressures from competitors and electric vehicle adoption delays in North America. As a result, during the fourth quarter of 2025, the Company recorded a goodwill impairment charge of $410 million related to the Battery & Charging Systems reporting unit.
The fair value of the Battery & Charging Systems reporting unit’s goodwill is sensitive to differences between estimated and actual cash flows, including changes in the projected revenue, projected operating margin and discount rate used to evaluate the fair value of these assets and market multiples assumptions applied by the Company. Future changes in the judgments, assumptions and estimates from those used in valuations and goodwill impairment testing, including discount rates or future operating results and related cash flow projections, could result in significantly different estimates of the fair values in the future. An increase in discount rates, a reduction in projected cash flows or a combination of the

two could lead to a reduction in the estimated fair values, which may result in impairment charges that could materially affect the Company’s financial statements in any given year.
Similar to goodwill, the Company can elect to perform the impairment test for indefinite-lived intangibles other than goodwill (primarily trade names) using a qualitative analysis, considering similar factors as outlined in the goodwill discussion, to determine if it is more-likely-than-not that the fair value of the trade names is less than the respective carrying values. If the Company elects to perform or is required to perform a quantitative analysis, the test consists of a comparison of the fair value of the indefinite-lived intangible asset to the carrying value of the asset as of the impairment testing date. The Company estimates the fair value of indefinite-lived intangibles using the relief-from-royalty method, which it believes is an appropriate and widely used valuation technique for such assets. The fair value derived from the relief-from-royalty method is measured as the discounted cash flow savings realized from owning such trade names and not being required to pay a royalty for their use.
Refer to Note 12, “Goodwill and Other Intangibles,” to the Consolidated Financial Statements in Item 8 of this report for more information regarding goodwill.
Product warranties The Company provides warranties on some, but not all, of its products. The warranty terms are typically from one to three years. Provisions for estimated expenses related to product warranty are made at the time products are sold. These estimates are established using historical information about the nature, frequency and average cost of warranty claim settlements as well as product manufacturing and industry developments and recoveries from third parties. Management actively studies trends of warranty claims and takes action to improve product quality and minimize warranty claims. Costs of product recalls, which may include the cost of the product being replaced as well as the customer’s cost of the recall, including labor to remove and replace the recalled part, are accrued as part of the Company’s warranty accrual at the time an obligation becomes probable and can be reasonably estimated. Management believes that the warranty accrual is appropriate; however, if actual claims incurred differ from the original estimates or there are changes in our assumptions, it could materially affect the Company’s financial statements.
At December 31, 2025, the total accrued warranty liability was $254 million. The accrual is represented as $86 million in Other current liabilities and $168 million in Other non-current liabilities on the Consolidated Balance Sheets.
Refer to Note 13, “Product Warranty,” to the Consolidated Financial Statements in Item 8 of this report for more information regarding product warranties.
Postretirement defined benefits The Company provides postretirement defined benefits to a number of its current and former employees. Costs associated with postretirement defined benefits include pension and other postemployment health care expenses for former employees, retirees and surviving spouses and dependents.
The Company’s defined benefit pension and other postemployment benefit plans are accounted for in accordance with ASC Topic 715. The determination of the Company’s obligation and expense for its pension and other postemployment benefits, such as retiree health care, is dependent on certain assumptions used by actuaries in calculating such amounts. Certain assumptions, including the expected long-term rate of return on plan assets, discount rate, rates of increase in compensation and health care costs trends are described in Note 18, “Retirement Benefit Plans,” to the Consolidated Financial Statements in Item 8 of this report. The effects of any modification to those assumptions, or actual results that differ from assumptions used, are either recognized immediately or amortized over future periods in accordance with GAAP.
57

Table of Contents
The primary assumptions affecting the Company’s accounting for employee benefits under ASC Topics 712 and 715 as of December 31, 2025 are as follows:
•Expected long-term rate of return on plan assets: The expected long-term rate of return is used in the calculation of net periodic benefit cost. The required use of the expected long-term rate of return on plan assets may result in recognized returns that are greater or less than the actual returns on those plan assets in any given year. Over time, however, the expected long-term rate of return on plan assets is designed to approximate actual earned long-term returns. The expected long-term rate of return for pension assets has been determined based on various inputs, including historical returns for the different asset classes held by the Company’s trusts and its asset allocation, as well as inputs from internal and external sources regarding expected capital market return, inflation and other variables. The Company also considers the impact of active management of the plans’ invested assets. In determining its pension expense for the year ended December 31, 2025, the Company used long-term rates of return on plan assets ranging from 2.8% to 7.9% outside of the U.S. and 5% in the U.S. The primary funded non-U.S. plans are in the U.K. and Germany.
Actual returns on U.S. pension assets were 7.3% and 0.6% for the years ended December 31, 2025 and 2024, respectively, compared to the expected rate of return assumptions of 5% for the years ended December 31, 2025 and 2024.
Actual returns on U.K. pension assets were 5.9% and (3.7)% for the years ended December 31, 2025 and 2024, respectively, compared to the expected rate of return assumption of 4.8% and 4.0%, respectively, for the same years ended.
Actual returns on German pension assets were 0.8% and 7.0% for the years ended December 31, 2025 and 2024, respectively, compared to the expected rate of return assumptions of 4.2% for the years ended December 31, 2025 and 2024.
•Discount rate: The discount rate is used to calculate pension and other postemployment benefit (“OPEB”) obligations. In determining the discount rate, the Company utilizes a full-yield approach in the estimation of service and interest components by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. For its significant plans, the Company used discount rates ranging from 1.0% to 10.5% to determine its pension and other benefit obligations as of December 31, 2025, including weighted average discount rates of 4.1% in the U.S., 4.6% outside of the U.S. (including 5.5% in the U.K.) and 4.9% for U.S. other postemployment health care plans. The U.S. and U.K. discount rates reflect the fact that the U.S. and U.K. pension plans have been closed for new participants.
•Health care cost trend: For postemployment employee health care plan accounting, the Company reviews external data and Company-specific historical trends for health care cost to determine the health care cost trend rate assumptions. In determining the projected benefit obligation for postemployment health care plans as of December 31, 2025, the Company used health care cost trend rates of 6.8%, declining to an ultimate trend rate of 4.8% by the year 2034.
While the Company believes that these assumptions are appropriate, significant differences in actual experience or significant changes in these assumptions may materially affect the Company's pension and OPEB and its future expense.

The sensitivity to a 25 basis point change in the assumptions for discount rate related to 2026 pre-tax pension expense for Company sponsored U.S. and non-U.S. pension plans is expected to be negligible.
The following table illustrates the sensitivity to a change in expected return on assets related to 2026 pre-tax pension expense for Company sponsored U.S. and non-U.S. pension:

(in millions) | Impact on U.S. PBO |  | Impact on Non-U.S. PBO
25 basis point decrease in expected return on assets | $ | 8 |  |  | $ | 1 |
25 basis point increase in expected return on assets | $ | (8) |  |  | $ | (1) |

The following table illustrates the sensitivity to a change in discount rate for Company sponsored U.S. and non-U.S. pension plans on its pension obligations:

(in millions) | Impact on U.S. PBO |  | Impact on Non-U.S. PBO
25 basis point decrease in discount rate | $ | 3 |  |  | $ | 14 |
25 basis point increase in discount rate | $ | (3) |  |  | $ | (13) |

The sensitivity to a 25 basis point change in the discount rate assumption and to the assumed health care cost trend related to the Company’s OPEB obligation and service and interest cost is expected to be negligible.
Refer to Note 18, “Retirement Benefit Plans,” to the Consolidated Financial Statements in Item 8 of this report for more information regarding the Company’s retirement benefit plans.
Restructuring Restructuring costs may occur when the Company takes action to exit or significantly curtail a part of its operations or implements a reorganization that affects the nature and focus of operations. A restructuring charge can consist of severance costs associated with reductions to the workforce, costs to terminate a contract, professional fees and other costs incurred related to the implementation of restructuring activities.
The Company generally records costs associated with voluntary separations at the time of employee acceptance. Costs for involuntary separation programs are recorded when management has approved the plan for separation, the employees are identified and aware of the benefits to which they are entitled and it is unlikely that the plan will change significantly. When a plan of separation requires approval by or consultation with the relevant labor organization or government, the costs are recorded upon agreement. Costs associated with benefits that are contingent on the employee continuing to provide service are expensed over the required service period.
Restructuring accruals can include estimates related to employee termination costs. Actual costs may vary from these estimates. These accruals are reviewed on a quarterly basis and changes to restructuring accruals are appropriately recognized when identified.
Income taxes The Company accounts for income taxes in accordance with ASC Topic 740. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax assets are reduced by a valuation allowance if, based on the weight of available evidence, it is more-likely-than-not that some portion or all of the deferred tax assets will not be realized.
Accounting for income taxes is complex, in part because the Company conducts business globally and, therefore, files income tax returns in numerous tax jurisdictions. Management judgment is required in
59

Table of Contents
determining the Company’s worldwide provision for income taxes and recording the related assets and liabilities, including accruals for unrecognized tax benefits and assessing the need for valuation allowances. In calculating the provision for income taxes on an interim basis, the Company uses an estimate of the annual effective tax rate based upon the facts and circumstances known at each interim period. In determining the need for a valuation allowance, the historical and projected financial performance of the operation recording the net deferred tax asset is considered along with any other pertinent information. Since future financial results may differ from previous estimates, periodic adjustments to the Company’s valuation allowance may be necessary.
The Company is subject to income taxes in the U.S. at the federal and state level and numerous non-U.S. jurisdictions. The determination of accruals for unrecognized tax benefits includes the application of complex tax laws in a multitude of jurisdictions across the Company's global operations. Management judgment is required in determining the accruals for unrecognized tax benefits. In the ordinary course of the Company’s business, there are many transactions and calculations where the ultimate tax determination is less than certain. Accruals for unrecognized tax benefits are established when, despite the belief that tax positions are supportable, there remain certain positions that do not meet the minimum probability threshold, which is a tax position that is more-likely-than-not to be sustained upon examination by the applicable taxing authority. The Company has certain U.S. state income tax returns and certain non-U.S. income tax returns that are currently under various stages of audit by applicable tax authorities. At December 31, 2025, the Company had a liability for tax positions the Company estimates are not more-likely-than-not to be sustained based on the technical merits, which is included in Other non-current liabilities. Nonetheless, the amounts ultimately paid, if any, upon resolution of the issues raised by the taxing authorities may differ materially from the amounts accrued for each year.
The Company records valuation allowances to reduce the carrying value of certain deferred tax assets to amounts that it expects are more-likely-than-not to be realized. Existing deferred tax assets, net operating losses and tax credits by jurisdiction and expectations of the ability to utilize these tax attributes are assessed through a review of past, current and estimated future taxable income and tax planning strategies.
Estimates of future taxable income, including income generated from prudent and feasible tax planning strategies resulting from actual or planned business and operational developments, could change in the near term, perhaps materially, which may require the Company to consider any potential impact to the assessment of the recoverability of the related deferred tax asset. Such potential impact could be material to the Company’s consolidated financial condition or results of operations for an individual reporting period.
In future periods, the Company’s effective tax rate and tax liability may be impacted due to changes in U.S. and non-U.S. tax laws and as a result of regulatory or legislative developments related to such laws. This could include U.S. and non-U.S. tax law developments related to changes to long-standing tax principles arising from proposals made by the Organization for Economic Co-operation and Development that seek to allocate greater taxing rights to countries where customers are located and establish a global minimum tax rate of at least 15%.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
The Company’s primary market risks include fluctuations in interest rates and foreign currency exchange rates. To manage these risks, the Company enters into a variety of derivative contracts with the intent of mitigating our risk to fluctuations in currency exchange rates and interest rates. The Company is also affected by changes in the prices of commodities used or consumed in its manufacturing operations. Some of its commodity purchase price risk is covered by supply agreements with customers and suppliers. Other commodity purchase price risk is occasionally addressed by hedging strategies, which include forward contracts. The Company enters into derivative instruments only with high credit quality counterparties and diversifies its positions across such counterparties to reduce its exposure to credit losses. The Company does not engage in any derivative instruments for purposes other than hedging specific operating risks.
The Company has established policies and procedures to manage sensitivity to interest rate, foreign currency exchange rate and commodity purchase price risk, which include monitoring the level of exposure to each market risk. For quantitative disclosures about market risk, refer to Note 17, “Financial Instruments,” to the Consolidated Financial Statements in Item 8 of this report for information with respect to interest rate risk, foreign currency exchange rate risk and commodity purchase price risk.
Interest Rate Risk
Interest rate risk is the risk that the Company will incur economic losses due to adverse changes in interest rates. The Company manages its interest rate risk by monitoring its exposure to fixed and variable rates while attempting to optimize its interest costs. The Company selectively uses interest rate swaps to reduce market value risk associated with changes in interest rates (fair value hedges). At December 31, 2025, all of the Company’s long-term debt had fixed interest rates.
Foreign Currency Exchange Rate Risk
Foreign currency exchange rate risk is the risk that the Company will incur economic losses due to adverse changes in foreign currency exchange rates. Currently, the Company’s most significant currency exposures relate to the Brazilian Real, British Pound, Chinese Renminbi, Euro, Hungarian Forint, Korean Won, Mexican Peso, Polish Zloty and Swiss Franc. The Company mitigates its foreign currency exchange rate risk by establishing local production facilities and related supply chain participants in the markets it serves, by invoicing customers in the same currency as the source of the products and by funding some of its investments in foreign markets through local currency loans. The Company also monitors its foreign currency exposure in each country and implements strategies to respond to changing economic and political environments. In addition, the Company regularly enters into forward currency contracts, cross-currency swaps and foreign currency-denominated debt designated as net investment hedges to reduce exposure to translation exchange rate risk. As of December 31, 2025 and 2024, the Company recorded a deferred loss of $35 million and a deferred gain of $245 million, respectively, before taxes, for designated cash flow and net investment hedges within accumulated other comprehensive income (loss) in the Consolidated Balance Sheets in Item 8 of this report.
The significant foreign currency translation adjustments, including the impact of the cash flow net investment hedges discussed above, during the years ended December 31, 2025 and 2024, are shown in the following table, which provides the percentage change in U.S. Dollars against the respective currencies and the approximate impacts of these changes recorded within other comprehensive income (loss) for the respective periods.

Commodity Price Risk
Commodity price risk is the possibility that the Company will incur economic losses due to adverse changes in the cost of raw materials used in the production of its products. Commodity forward and option contracts are occasionally executed to offset exposure to potential change in prices mainly for various non-ferrous metals and natural gas consumption used in the manufacturing of vehicle components. As of December 31, 2025 and 2024, the Company had no outstanding commodity swap contracts.

Report of Independent Registered Public Accounting Firm
To the Board of Directors and Stockholders of BorgWarner Inc.
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of BorgWarner Inc. and its subsidiaries (the "Company") as of December 31, 2025 and 2024, and the related consolidated statements of operations, of comprehensive income, of equity and of cash flows for each of the three years in the period ended December 31, 2025, including the related notes (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of 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 consolidated financial statements referred to above 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. Also 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 the COSO.
Basis for Opinions
The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
64

Table of Contents
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matters
The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
Worldwide Provision for Income Taxes
As described in Notes 1 and 7 to the consolidated financial statements, the Company recorded a provision for income taxes of $189 million for the year ended December 31, 2025. Management judgment is required in determining the Company’s worldwide provision for income taxes and recording the related assets and liabilities, including accruals for unrecognized tax benefits and assessing the need for valuation allowances. Accounting for income taxes is complex, in part because the Company conducts business globally and, therefore, files income tax returns in numerous tax jurisdictions. As disclosed by management, the Company is subject to income taxes in the U.S. at the federal and state level and numerous non-U.S. jurisdictions. In the ordinary course of the Company’s business, there are many transactions and calculations where the ultimate tax determination is less than certain. Accruals for unrecognized tax benefits are established when, despite the belief that tax positions are supportable, there remain certain positions that do not meet the minimum probability threshold, which is a tax position that is more-likely-than-not to be sustained upon examination by the applicable taxing authority. The determination of accruals for unrecognized tax benefits includes the application of complex tax laws in a multitude of jurisdictions across the Company’s global operations. The Company records valuation allowances to reduce the carrying value of deferred tax assets to amounts that it expects are more-likely-than-not to be realized. The Company assesses existing deferred tax assets, net operating losses and tax credit carryforwards by jurisdiction and expectations of its ability to utilize these tax attributes through a review of past, current, and estimated future taxable income.
The principal considerations for our determination that performing procedures relating to the worldwide provision for income taxes is a critical audit matter are (i) the significant judgment by management when developing the worldwide provision for income taxes; (ii) a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating management’s worldwide provision for income taxes, including the accruals for unrecognized tax benefits and valuation allowances on deferred tax assets; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the worldwide provision for income taxes, including controls over accruals for unrecognized tax benefits and valuation allowances on deferred tax assets. These procedures also included, among others (i) testing the worldwide provision for income taxes, including the effective tax rate reconciliation, return to provision adjustments, and permanent and temporary differences; (ii) evaluating the completeness of management’s assessment of the identification of tax positions where the tax determination is less than certain, possible outcomes of each less than certain tax position based on the application of relevant tax laws, and the amount of the potential benefit to be realized, including estimated interest and penalties; (iii) evaluating the reasonableness of management’s more-likely-than-not determination of less than certain tax positions in consideration of the tax laws in relevant jurisdictions; (iv) testing the completeness and accuracy of underlying data used in measuring and recognizing deferred tax assets and liabilities; and (v) evaluating management’s assessment of the realizability of deferred tax assets on a jurisdictional basis based on expectations of the ability to utilize its tax attributes through a review of historical and estimated future taxable income. Professionals with specialized skill and knowledge were used to assist in testing (i) foreign tax credits; (ii) foreign-derived intangible income deductions; (iii) the impact of distributions from foreign affiliates; and (iv) evaluating the reasonableness of management’s indefinite reinvestment assertion.

Goodwill Impairment Assessment – Battery & Charging Systems Reporting Unit
As described in Notes 1 and 12 to the consolidated financial statements, the Company’s consolidated goodwill balance was $2,055 million as of December 31, 2025, and the goodwill associated with the Battery & Charging Systems reporting unit was $146 million. During the fourth quarter of each year, management tests goodwill for impairment by either performing a qualitative assessment or a quantitative analysis. During the fourth quarter of 2025, management noted deterioration in the forecast for its Battery & Charging Systems business. This deterioration was due to dual sourcing actions by certain customers and electric vehicle adoption delays in North America. Therefore, as a result of the fourth quarter goodwill impairment test, management recorded a goodwill impairment charge of $410 million related to the Battery & Charging Systems reporting unit. The estimated fair values were determined using a discounted cash flow model (income approach). The significant assumptions affecting management’s cash flow projections for the Battery & Charging Systems reporting unit included discount rates, operating income (loss) margins, and revenue growth rates.
The principal considerations for our determination that performing procedures relating to the goodwill impairment assessment of the Battery & Charging Systems reporting unit is a critical audit matter are (i) the significant judgment by management when developing the fair value estimate of the Battery & Charging Systems reporting unit; (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management’s significant assumptions related to the discount rate, operating income (loss) margins, and revenue growth rates; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s goodwill impairment assessment, including controls over the valuation of the Battery & Charging Systems reporting unit. These procedures also included, among others (i) testing management’s process for developing the fair value estimate of the Battery & Charging Systems reporting unit; (ii) evaluating the appropriateness of the discounted cash flow model used by management; (iii) testing the completeness and accuracy of underlying data used in the discounted cash flow model; and (iv) evaluating the reasonableness of the significant assumptions used by management related to the discount rate, operating income (loss) margins, and revenue growth rates. Evaluating management’s assumptions related to the operating income (loss) margins and revenue growth rates involved evaluating whether the assumptions used by management were reasonable considering (i) the current and past performance of the Battery & Charging Systems reporting unit; (ii) the consistency with external market and industry data; and (iii) whether the assumptions were consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and knowledge were used to assist in evaluating (i) the appropriateness of the discounted cash flow model and (ii) the reasonableness of the discount rate assumption.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
INTRODUCTION
BorgWarner Inc. and Consolidated Subsidiaries (the “Company” or “BorgWarner”) is a Delaware corporation incorporated in 1987. The Company is a global product leader in clean and efficient technology solutions for combustion, hybrid and electric vehicles. BorgWarner’s products help improve vehicle performance, propulsion efficiency, stability and air quality. The Company manufactures and sells these products worldwide, primarily to original equipment manufacturers (“OEMs”) of light vehicles (passenger cars, sport-utility vehicles, vans and light trucks). The Company's products are also sold to OEMs of commercial vehicles (medium-duty trucks, heavy-duty trucks and buses) and off-highway vehicles (agricultural and construction machinery and marine applications). The Company also manufactures and sells its products to certain tier one vehicle systems suppliers and into the aftermarket for light, commercial and off-highway vehicles. The Company operates manufacturing facilities serving customers in Europe, the Americas and Asia and is an original equipment supplier to nearly every major automotive OEM in the world.
On July 3, 2023, BorgWarner completed the spin-off (“Spin-Off”) of its Fuel Systems and Aftermarket segments in a transaction intended to qualify as tax free to the Company’s stockholders for U.S. federal income tax purposes, which was accomplished by the distribution of 100% of the outstanding common stock of PHINIA, Inc. (“PHINIA”) to holders of record of common stock of the Company on a pro-rata basis.
The historical results of operations of PHINIA for periods prior to the Spin-Off are presented as discontinued operations in these Consolidated Financial Statements.
NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
The following paragraphs briefly describe the Company’s significant accounting policies.
Basis of presentation Certain prior period amounts have been reclassified to conform to current period presentation. Additionally, in the year ended December 31, 2024, the Company recognized a $19 million increase in Net earnings attributable to BorgWarner Inc. in the Consolidated Statement of Operations for the correction of misstatements related to certain accruals, of which $12 million related to 2023 (the remainder relates to periods prior to 2023). The Company has evaluated the effect of these out-of-period adjustments for the interim and annual reporting periods in 2024, as well as on the previous interim and annual periods in which they should have been recognized, and concluded that these adjustments are not material to any of the periods affected.
As discussed in the Introduction above, as a result of the Spin-Off, the historical results of operations and the financial position of PHINIA for periods prior to the Spin-Off are presented as discontinued operations in these Consolidated Financial Statements. Refer to Note 26, “Discontinued Operations,” to the Consolidated Financial Statements for more information.
The Company’s Consolidated Financial Statements reflect the results of acquisitions following the date of the respective acquisition. Refer to Note 2, “Acquisitions and Dispositions,” to the Consolidated Financial Statements for more information.
Use of estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the accompanying notes, as well as the amounts of revenues and expenses reported during the periods

covered by these financial statements and accompanying notes. Actual results could differ from those estimates.
Principles of consolidation The Consolidated Financial Statements include all majority-owned subsidiaries in which the Company has a controlling financial interest. All inter-company balances and transactions have been eliminated in consolidation.
Change in accounting method Prior to 2024, certain of the Company’s U.S. inventories were accounted for under the last-in, first-out (“LIFO”) method of accounting. During the fourth quarter of 2024, the Company changed the inventory valuation method for those locations from LIFO to the first-in, first-out (“FIFO”) method. FIFO was deemed a preferable method as it better aligns with the accounting practices of the Company’s peers, it more accurately reflects the current value and physical flow of inventory and it harmonizes the accounting method for the majority of inventories across the Company. Retroactive application of the change to prior periods did not have a material impact on any prior periods’ Consolidated Financial Statements, and therefore the Company recognized the cumulative effect of the change in the fourth quarter of 2024 as a reduction in Cost of sales of $29 million in the Consolidated Statements of Operations, which resulted in an increase in income before taxes of $29 million ($22 million after tax) for the three months ended December 31, 2024 with a corresponding increase in Inventories within the Consolidated Balance Sheet as of December 31, 2024.
Joint ventures and equity securities The Company has investments in three unconsolidated joint ventures, NSK-Warner K.K., Turbo Energy Private Limited and Fast Warner Intelligent Control Systems Co., Ltd. of which the Company owns 50%, 32.6% and 49.0%, respectively. These joint ventures are non-controlled affiliates in which the Company exercises significant influence but does not have a controlling financial interest and, therefore, are accounted for under the equity method. Generally, under the equity method, the Company’s original investments in these joint ventures are recorded at cost and subsequently adjusted by the Company’s share of equity in income or losses. The Company monitors its equity method investments for indicators of other-than-temporary declines in fair value on an ongoing basis. If such a decline has occurred, an impairment charge is recorded, which is measured as the difference between the carrying value and the estimated fair value. The Company’s investment in these non-controlled affiliates is included within Investments and long-term receivables in the Consolidated Balance Sheets. The Company’s share of equity in income or losses is included in Equity in affiliates’ earnings, net of tax in the Consolidated Statements of Operations.
The Company also has certain investments for which it does not have the ability to exercise significant influence (generally when ownership interest is less than 20%). The Company’s investment in these equity securities is included within Investments and long-term receivables in the Consolidated Balance Sheet. Refer to Note 10, “Other Current and Non-Current Assets,” to the Consolidated Financial Statements for more information.
Interests in privately held companies that do not have readily determinable fair values are accounted for using the measurement alternative under Accounting Standards Codification (“ASC”) Topic 321, “Investments - Equity Securities,” which includes monitoring on an ongoing basis for indicators of impairments or upward adjustments. These equity securities are measured at cost less impairments, adjusted for observable price changes in orderly transactions for the identical or similar investment of the same issuer. If the Company determines that an indicator of impairment or upward adjustment is present, an adjustment is recorded, which is measured as the difference between carrying value and estimated fair value. Estimated fair value is generally determined using an income approach on discounted cash flows or negotiated transaction values.
Equity securities that have readily determinable fair values are measured at fair value. Equity securities that do not have a readily determinable fair value and which provide a net asset value (“NAV”) or its equivalent, are valued using NAV as a practical expedient. Changes in fair value and NAV are recorded in

Unrealized and realized (gain) loss on equity and debt securities in the Consolidated Statements of Operations.
Debt securities During 2022, the Company invested $500 million in convertible debt securities of Wolfspeed, Inc. (“Wolfspeed”) as part of a strategic partnership with Wolfspeed. The Company elected to classify the debt security as trading and remeasured the investment quarterly using fair value in accordance with ASC Topic 320, “Investments.” In 2023, the investment in Wolfspeed was disposed and the Company recorded a loss in Unrealized and realized (gain) loss on equity and debt securities in the Consolidated Statements of Operations. Prior to the disposition, the changes in fair value were recorded in Unrealized and realized (gain) loss on equity and debt securities in the Consolidated Statements of Operations.
Business combinations In accordance with ASC Topic 805, “Business Combinations,” acquisitions are recorded using the acquisition method of accounting. The Company includes the operating results of acquired entities from their respective dates of acquisition. The Company recognizes and measures the identifiable assets acquired, liabilities assumed, and any non-controlling interest at the acquisition date fair value. Various valuation techniques are used to determine the fair value of intangible assets, with the primary techniques being forms of the income approach, specifically the relief-from-royalty and multi-period excess earnings valuation methods. Under these valuation approaches, the Company is required to make estimates and assumptions from a market participant perspective that may include revenue growth rates, estimated earnings, royalty rates, obsolescence factors, contributory asset charges, customer attrition and discount rates. The excess, if any, of total consideration transferred in a business combination over the fair value of identifiable assets acquired, liabilities assumed and any non-controlling interest is recognized as goodwill. Costs incurred as a result of a business combination other than costs related to the issuance of debt or equity securities are recorded in the period the costs are incurred. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to assets acquired and liabilities assumed with the corresponding offset to goodwill.
Revenue recognition Revenue is recognized when performance obligations under the terms of a contract are satisfied, which generally occurs with the transfer of control of the products. For most products, transfer of control occurs upon shipment or delivery; however, a limited number of customer arrangements for highly customized products with no alternative use provide the Company with the right to payment during the production process. As a result, for these limited arrangements, revenue is recognized as goods are produced and control transfers to the customer using the input cost-to-cost method. Revenue is measured at the amount of consideration the Company expects to receive in exchange for transferring the goods. Although the Company may enter into long-term supply arrangements with its major customers, the prices and volumes are not fixed over the life of the arrangements, and a contract does not exist for purposes of applying ASC Topic 606, “Revenue from Contracts with Customers,” until volumes are contractually known.
Sales incentives and allowances (including returns) are recognized as a reduction to revenue at the time of the related sale. The Company estimates the allowances based on an analysis of historical experience. Taxes assessed by a governmental authority collected by the Company concurrent with a specific revenue-producing transaction are excluded from net sales. Shipping and handling fees billed to customers are included in sales, while costs of shipping and handling are included in cost of sales. The Company has elected to apply the accounting policy election available under ASC Topic 606 and accounts for shipping and handling activities as a fulfillment cost.
The Company has a limited number of arrangements with customers where the price paid by the customer is dependent on the volume of product purchased over the term of the arrangement. In other arrangements, the Company will provide a rebate to customers based on the volume of products purchased during the course of the arrangement. The Company estimates the volumes to be sold over

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
the term of the arrangement and recognizes revenue based on the estimated amount of consideration to be received from these arrangements.
The Company continually seeks business development opportunities and at times provides customer incentives for new program awards. The Company evaluates the underlying economics of each amount of consideration payable to a customer to determine the proper accounting by understanding the reasons for the payment, the rights and obligations resulting from the payment, the nature of the promise in the contract, and other relevant facts and circumstances. When the Company determines that the payments are incremental and incurred only if the new business is obtained and expects to recover these amounts from the customer over the term of the new business arrangement, the Company capitalizes these amounts. The Company recognizes a reduction to revenue as products that the upfront payments are related to are transferred to the customer, based on the total amount of products expected to be sold over the term of the arrangement (generally three to seven years). The Company evaluates the amounts capitalized each period end for recoverability and recognizes a reduction to revenue for any amounts that are no longer expected to be recovered over the term of the business arrangement.
Refer to Note 3, “Revenue from Contracts with Customers,” to the Consolidated Financial Statements for more information.
Cost of sales The Company includes materials, direct labor and manufacturing overhead within cost of sales. Manufacturing overhead is comprised of indirect materials, indirect labor, factory operating costs, warranty costs and other such costs associated with manufacturing products for sale.
Cash and cash equivalents Cash and cash equivalents are valued at fair market value. It is the Company's policy to classify all highly liquid investments with original maturities of three months or less as cash and cash equivalents. Cash and cash equivalents are maintained with several financial institutions. Deposits held with banks may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and are maintained with financial institutions of reputable credit and, therefore, bear minimal risk.
Restricted cash Restricted cash includes amounts designated for uses other than current operations and is legally restricted as to use or withdrawal. As of December 31, 2025 and 2024, the Company had no restricted cash.
Receivables, net and long-term receivables Accounts receivable and long-term receivables are stated at cost less an allowance for credit losses. An allowance for credit losses is recorded for amounts that may become uncollectible in the future. The allowance for credit losses is an estimate based on expected losses, current economic and market conditions, and a review of the current status of each customer’s accounts receivable.
Inventories Inventory is measured using FIFO or average-cost methods at the lower of cost or net realizable value.
Pre-production costs related to long-term supply arrangements Engineering, research and development and other design and development costs for products sold on long-term supply arrangements are expensed as incurred unless the Company has a contractual guarantee for reimbursement from the customer. Costs for molds, dies and other tools used to make products sold on long-term supply arrangements for which the Company has title to the assets are capitalized in property, plant and equipment and amortized to cost of sales over the shorter of the term of the arrangement or over the estimated useful lives of the assets, typically three to five years. Costs for molds, dies and other tools used to make products sold on long-term supply arrangements for which the Company has a contractual guarantee for lump sum reimbursement from the customer are capitalized in prepayments and other current assets.

Property, plant and equipment, net Property, plant and equipment is valued at cost less accumulated depreciation. Expenditures for maintenance, repairs and renewals of relatively minor items are generally charged to expense as incurred. Renewals of significant items are capitalized. Depreciation is generally computed on a straight-line basis over the estimated useful lives of the assets. Useful lives for buildings range from 15 to 40 years, and useful lives for machinery and equipment range from three to 12 years. For income tax purposes, accelerated methods of depreciation are generally used. Refer to Note 11, “Property, Plant and Equipment, Net,” to the Consolidated Financial Statements for more information.
Impairment of long-lived assets, including definite-lived intangible assets The Company reviews the carrying value of its long-lived assets, whether held for use or disposal, including other amortizing intangible assets, when events and circumstances warrant such a review under ASC Topic 360, “Property, Plant and Equipment.” In assessing long-lived assets for an impairment loss, assets are grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. In assessing long-lived assets for impairment, management generally considers individual facilities to be the lowest level for which identifiable cash flows are largely independent. A recoverability review is performed using the undiscounted cash flows if there is a triggering event. If the undiscounted cash flow test for recoverability identifies a possible impairment, management will perform a fair value analysis. Management determines fair value under ASC Topic 820, “Fair Value Measurement,” using the appropriate valuation technique of market, income or cost approach. If the carrying value of a long-lived asset is considered impaired, an impairment charge is recorded for the amount by which the carrying value of the long-lived asset exceeds its fair value. The Company’s impairment loss is calculated based on independent appraisals, discounted cash flows, estimated salvage value, or estimated orderly liquidation value, giving consideration to the highest and best use of the relevant assets.
Management believes that the estimates of future cash flows and fair value assumptions are reasonable; however, changes in assumptions underlying these estimates could affect the valuations. Significant judgments and estimates used by management when evaluating long-lived assets for impairment include (i) an assessment as to whether an adverse event or circumstance has triggered the need for an impairment review; (ii) undiscounted future cash flows generated by the asset; and (iii) fair valuation of the asset.
During the year ended December 31, 2025, the Company recorded impairments of $174 million related to certain property, plant and equipment. The recorded impairments were as follows:
•During the year ended December 31, 2025, the Company recorded impairments of property, plant and equipment of $7 million related to the exit of its charging business and the consolidation of the Company’s North American battery systems business footprint within the Battery & Charging Systems reportable segment. The Company estimated fair value using estimated orderly liquidation value based on the Company’s determination of the highest and best use of the relevant assets.
•In the fourth quarter of 2025, the Company recorded impairment of property, plant and equipment of $167 million related to customer volume reduction as a result of electric vehicle adoption delays in North America within the PowerDrive Systems reportable segment and dual sourcing actions by certain customers and pricing pressures from competitors within the Battery & Charging Systems reportable segment. The Company estimated fair value using discounted cash flows and estimated orderly liquidation value based on the Company’s determination of the highest and best use of the relevant assets.
During the year ended December 31, 2025, the Company recorded intangible asset impairment assets of $27 million, of which $22 million related to exit of its charging business and the consolidation of the

Company’s North American battery systems business footprint within the Battery & Charging Systems reportable segment. Refer to Note 2, “Acquisitions and Dispositions,” to the Consolidated Financial Statements for more information. Additionally, the Company recorded impairment of $5 million related to intangible assets at PowerDrive Systems.
During the year ended December 31, 2024, the Company recorded impairment charges of $69 million related to certain property, plant and equipment at locations in the Company’s Battery & Charging Systems and PowerDrive Systems reporting segments. In the fourth quarter of 2024, the Company noted deterioration in the forecast of its PowerDrive Systems and Battery & Charging Systems businesses due to further decreases in demand for eProducts as compared to the Company’s expectations as a result of electric vehicle adoption volatility across different regions. This was viewed as a triggering event, and as a result, individual facilities were tested for recoverability. These impairment charges related to locations that failed a recoverability test or where management had initiated plans to liquidate certain assets.
During the year ended December 31, 2023, the Company recorded charges of $29 million, related to the impairment of certain operating lease assets, a customer incentive asset and certain property, plant and equipment.
The charges referenced above were recognized in Impairment charges within the Consolidated Statements of Operations.
In addition, the Company recognized accelerated depreciation charges of $90 million, $50 million and $4 million during the years ended December 31, 2025, 2024 and 2023, respectively. These charges related to property, plant and equipment that were decommissioned or were in the process of being decommissioned.
Goodwill and other intangible assets During the fourth quarter of each year, the Company tests goodwill for impairment by either performing a qualitative assessment or a quantitative analysis. In addition, the Company may test goodwill in between annual test dates if an event occurs or circumstances change that could indicate it is more-likely-than-not that the fair value of a reporting unit is below its carrying value.
The qualitative assessment evaluates various events and circumstances, such as macroeconomic conditions, industry and market conditions, cost factors, relevant events and financial trends, that may impact a reporting unit's fair value. Using this qualitative assessment, the Company determines whether it is more-likely-than-not that the reporting unit's fair value exceeds its carrying value. If it is determined that it is not more-likely-than-not the reporting unit's fair value exceeds the carrying value, or upon consideration of other factors, including recent acquisition, restructuring or disposal activity or to refresh the fair values, the Company performs a quantitative goodwill impairment analysis.
The Company has definite-lived intangible assets related to patents and developed technology, customer relationships and trade names. The Company amortizes definite-lived intangible assets over their estimated useful lives. The Company also has intangible assets related to acquired trade names that are classified as indefinite-lived when there are no foreseeable limits on the periods of time over which they are expected to contribute cash flows. Costs to renew or extend the term of acquired intangible assets are recognized as expense as incurred.

Similar to goodwill, the Company can elect to perform the impairment test for indefinite-lived intangibles other than goodwill (primarily trade names) using a qualitative analysis, considering similar factors as outlined in the goodwill discussion, to determine if it is more-likely-than-not that the fair value of the trade names is less than the respective carrying values. If the Company elects to perform or is required to perform a quantitative analysis, the test consists of a comparison of the fair value of the indefinite-lived intangible asset to the carrying value of the asset as of the impairment testing date. The Company estimates the fair value of indefinite-lived intangibles using the relief-from-royalty method, which it believes is an appropriate and widely used valuation technique for such assets. The fair value derived from the relief-from-royalty method is measured as the discounted cash flow savings realized from owning such trade names and not being required to pay a royalty for their use.
During the year ended December 31, 2025, the Company recorded charges of $423 million related to the goodwill at Battery & Charging Systems. Refer to Note 2, “Acquisitions and Dispositions,” and Note 12, “Goodwill and Other Intangibles,” to the Consolidated Financial Statements for more information. During the year ended December 31, 2024, the Company recorded charges of $577 million primarily related to the goodwill at PowerDrive Systems and Battery & Charging Systems. Refer to Note 12, “Goodwill and Other Intangibles,” to the Consolidated Financial Statements for more information.
These charges were recognized in Impairment charges within the Consolidated Statements of Operations.
Assets and liabilities held for sale The Company classifies assets and liabilities (disposal groups) to be sold as held for sale in the period in which all of the following criteria are met: (1) management, having the authority to approve the action, commits to a plan to sell the disposal group; (2) the disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such disposal groups; (3) an active program to locate a buyer and other actions required to complete the plan to sell the disposal group have been initiated; (4) the sale of the disposal group is probable, and transfer of the disposal group is expected to qualify for recognition as a completed sale within one year, except if events or circumstances beyond the Company’s control extend the period of time required to sell the disposal group beyond one year; (5) the disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (6) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.
The Company initially measures a disposal group that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a disposal group until the date of sale. The Company assesses the fair value of a disposal group, less any costs to sell, each reporting period it remains classified as held for sale and reports any subsequent changes as an adjustment to the carrying value of the disposal group, as long as the new carrying value does not exceed the carrying value of the disposal group at the time it was initially classified as held for sale. Additionally, depreciation is not recorded during the period in which the long-lived assets, included in the disposal group are classified as held for sale.
Upon determining that a disposal group meets the criteria to be classified as held for sale, the Company reports the assets and liabilities of the disposal group, if material, in the line items assets held for sale and liabilities held for sale in the Consolidated Balance Sheets.
Product warranties The Company provides warranties on some, but not all, of its products. The warranty terms are typically from one to three years. Provisions for estimated expenses related to product warranty are made at the time products are sold. These estimates are established using historical information about the nature, frequency and average cost of warranty claim settlements as well as product manufacturing and industry developments and recoveries from third parties. The Company

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
actively studies trends of warranty claims and takes action to improve product quality and minimize warranty claims. Costs of product recalls, which may include the cost of the product being replaced as well as the customer’s cost of the recall, including labor to remove and replace the recalled part, are accrued as part of the Company’s warranty accrual at the time an obligation becomes probable and can be reasonably estimated. The Company believes that the warranty accrual is appropriate; however, actual claims incurred could differ from the original estimates, requiring adjustments to the accrual. The product warranty accrual is allocated to current and non-current liabilities in the Consolidated Balance Sheets.
Refer to Note 13, “Product Warranty,” to the Consolidated Financial Statements for more information.
Other loss accruals and valuation allowances The Company has numerous other loss exposures, such as customer claims, workers’ compensation claims, litigation and recoverability of certain assets. Establishing loss accruals or valuation allowances for these matters requires the use of estimates and judgment in regard to the risk exposure and ultimate realization. The Company estimates losses using consistent and appropriate methods; however, changes to its assumptions could materially affect the recorded accrued liabilities for loss or asset valuation allowances.
Environmental contingencies The Company accounts for environmental costs in accordance with ASC Topic 450, “Contingencies.” Costs related to environmental assessments and remediation efforts at operating facilities are accrued when it is probable that a liability has been incurred and the amount of that liability can be reasonably estimated. Estimated costs are recorded at undiscounted amounts, based on experience and assessments and are regularly evaluated. The liabilities are recorded in Other current and Other non-current liabilities in the Company’s Consolidated Balance Sheets.
Refer to Note 21, “Contingencies,” to the Consolidated Financial Statements for more information.
Government grants The Company periodically receives government grants representing assistance provided by a government. These government grants are generally received in cash and typically provide reimbursement related to acquisition of property and equipment, product development or local governmental economic relief. The government grants are generally amortized using a systematic and rational method over the life of the grant. As of December 31, 2025, the Company recorded government grant related liabilities of $11 million in Other current liabilities and $74 million in Other non-current liabilities in the Company’s Consolidated Balance Sheet. During the year ended December 31, 2025, the Company recorded $46 million and $8 million of government grant-related credits in Selling, general and administrative expenses and Cost of sales, respectively, in the Company’s Consolidated Statement of Operations.
Derivative financial instruments The Company recognizes that certain normal business transactions and foreign currency operations generate risk. Examples of risks include exposure to foreign currency exchange rate risk related to transactions denominated in currencies other than the functional currency, changes in commodity costs and interest rates. It is the objective of the Company to assess the impact of these transaction risks and offer protection from selected risks through various methods, including financial derivatives. Virtually all derivative instruments held by the Company are designated as hedges, have high correlation with the underlying exposure and are highly effective in offsetting underlying price movements. Accordingly, gains and losses from changes in qualifying hedge fair values are matched with the underlying transactions. Hedge instruments are generally reported gross, with no right to offset, on the Consolidated Balance Sheets at their fair value based on quoted market prices for contracts with similar maturities. The Company does not engage in any derivative transactions for purposes other than hedging specific operational risks.
Refer to Note 17, “Financial Instruments,” to the Consolidated Financial Statements for more information.

Foreign currency The financial statements of foreign subsidiaries are translated to U.S. Dollars using the period-end exchange rate for assets and liabilities and an average exchange rate for each period for revenues, expenses and capital expenditures. The local currency is the functional currency for substantially all of the Company's foreign subsidiaries. Translation adjustments for foreign subsidiaries are recorded as a component of accumulated other comprehensive income (loss) in equity. The Company recognizes transaction gains and losses arising from fluctuations in currency exchange rates on transactions denominated in currencies other than the functional currency in earnings as incurred.
Refer to Note 20, “Accumulated Other Comprehensive Loss,” to the Consolidated Financial Statements for more information.
Postretirement defined benefits The Company’s defined benefit pension and other postemployment benefit plans are accounted for in accordance with ASC Topic 715, “Compensation - Retirement Benefits.” Disability, early retirement and other postemployment benefits are accounted for in accordance with ASC Topic 712, “Compensation - Nonretirement Postemployment Benefits.”
Pensions and other postemployment benefit costs and related liabilities and assets are dependent upon assumptions used in calculating such amounts. These assumptions include discount rates, expected returns on plan assets, health care cost trends, compensation and other factors. In accordance with GAAP, actual results that differ from the assumptions used are accumulated and amortized over future periods, and accordingly, generally affect recognized expense in future periods.
Refer to Note 18, “Retirement Benefit Plans,” to the Consolidated Financial Statements for more information.
Restructuring Restructuring costs may occur when the Company takes action to exit or significantly curtail a part of its operations or implements a reorganization that affects the nature and focus of operations. A restructuring charge can consist of severance costs associated with reductions to the workforce, costs to terminate an operating lease or contract, professional fees and other costs incurred related to the implementation of restructuring activities.
The Company generally records costs associated with voluntary separations at the time of employee acceptance. Costs for involuntary separation programs are recorded when management has approved the plan for separation, the employees are identified and aware of the benefits to which they are entitled and it is unlikely that the plan will change significantly. When a plan of separation requires approval by or consultation with the relevant labor organization or government, the costs are recorded upon agreement. Costs associated with benefits that are contingent on the employee continuing to provide service are expensed over the required service period.
Refer to Note 4, “Restructuring,” to the Consolidated Financial Statements for more information.
Income taxes In accordance with ASC Topic 740, “Income Taxes,” the Company’s income tax expense is calculated based on expected income and statutory tax rates in the various jurisdictions in which the Company operates and requires the use of management’s estimates and judgments. Accounting for income taxes is complex, in part because the Company conducts business globally and, therefore, files income tax returns in numerous tax jurisdictions. Management judgment is required in determining the Company’s worldwide provision for income taxes and recording the related assets and liabilities, including accruals for unrecognized tax benefits and assessing the need for valuation allowances.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
The determination of accruals for unrecognized tax benefits includes the application of complex tax laws in a multitude of jurisdictions across the Company’s global operations. Management judgment is required in determining the gross unrecognized tax benefits’ related liabilities. In the ordinary course of the Company’s business, there are many transactions and calculations where the ultimate tax determination is less than certain. Accruals for unrecognized tax benefits are established when, despite the belief that tax positions are supportable, there remain certain positions that do not meet the minimum probability threshold, which is a tax position that is more-likely-than-not to be sustained upon examination by the applicable taxing authority.
The Company records valuation allowances to reduce the carrying value of deferred tax assets to amounts that it expects are more-likely-than-not to be realized. The Company assesses existing deferred tax assets, net operating losses and tax credit carryforwards by jurisdiction and expectations of its ability to utilize these tax attributes through a review of past, current and estimated future taxable income and tax planning strategies.
Refer to Note 7, “Income Taxes,” to the Consolidated Financial Statements for more information.

NOTE 2 ACQUISITIONS AND DISPOSITIONS
Acquisitions
In accordance with ASC Topic 805, “Business Combinations,” acquisitions are recorded using the acquisition method of accounting. The Company recognizes and measures the acquisition date fair value of the identifiable assets acquired, liabilities assumed, and any non-controlling interest using a range of methodologies as indicated by generally accepted valuation practices. Various valuation techniques are used to determine the fair value of intangible assets, with the primary techniques being forms of the income approach, specifically the relief-from-royalty and multi-period excess earnings valuation methods. Under these valuation approaches, the Company is required to make estimates and assumptions from a market participant perspective and may include revenue growth rates, estimated earnings, royalty rates, obsolescence factors, contributory asset charges, customer attrition and discount rates.
Due to the insignificant size of the Company’s 2023 and 2022 acquisitions, both individually and in the aggregate, relative to the Company, supplemental pro forma financial information for the current and prior reporting periods is not provided.

The majority of the charging business related to the SSE business, which was marketed for sale and met the criteria to be reported as held-for-sale as of March 31, 2025. The SSE business sale closed in the second quarter of 2025 with proceeds totaling approximately $7 million. During the year ended December 31, 2025, the Company recorded charges of $22 million related to the loss on the sale of the SSE business. The other locations within the charging business ceased operations during the second quarter of 2025 and did not meet the criteria to be reported as held-for-sale.

NOTE 3 REVENUE FROM CONTRACTS WITH CUSTOMERS
The Company manufactures and sells products, primarily to OEMs of light vehicles and, to a lesser extent, to OEMs of commercial vehicles and off-highway vehicles, to certain tier one vehicle systems suppliers and into the aftermarket. The Company’s payment terms are based on customary business practices and vary by customer type and products offered. The Company has evaluated the terms of its arrangements and determined that they do not contain significant financing components.
Generally, revenue is recognized upon shipment or delivery; however, a limited number of the Company’s customer arrangements for its highly customized products with no alternative use provide the Company with the right to payment during the production process. As a result, for these limited arrangements, revenue is recognized as goods are produced and control transfers to the customer using the input cost-to-cost method. The Company recorded a contract asset of $15 million December 31, 2025 and 2024, for these arrangements. These amounts are reflected in Prepayments and other current assets in the Company’s Consolidated Balance Sheets.
In limited instances, certain customers have provided payments in advance of receiving related products, typically at the onset of an arrangement prior to the beginning of production. These contract liabilities are reflected as Other current liabilities and Other non-current liabilities in the Consolidated Balance Sheets. As of December 31, 2025, Other current liabilities and Other non-current liabilities were $1 million, respectively. As of December 31, 2024, Other current liabilities and Other non-current liabilities were $13 million and $29 million, respectively. These amounts are reflected as revenue over the term of the arrangement (typically three to seven years) as the underlying products are shipped and represent the Company’s remaining performance obligations as of the end of the period.
The Company continually seeks business development opportunities and at times provides customer incentives for new program awards. When the Company determines that the payments are incremental and incurred only if the new business is obtained and expects to recover these amounts from the customer over the term of the new business arrangement, the Company capitalizes these amounts. As of December 31, 2025 and 2024, the Company recorded customer incentive payments of $7 million and $22 million, respectively, in Prepayments and other current assets, and $22 million and $23 million, respectively, in Other non-current assets in the Consolidated Balance Sheets. The Company evaluates the amounts capitalized each period end for recoverability and writes off any amounts that are no longer expected to be recovered over the term of the business arrangement. During the year ended December 31, 2025 , the Company wrote off a $7 million customer incentive asset, which was recorded in Net sales in the Company’s Consolidated Statements of Operations.
The Company’s products can be disaggregated by two types: eProducts and Foundational products. eProducts include all products utilized on or for electric vehicles (“EVs”) plus those same products and components that are included in hybrid powertrains whose underlying technologies are adaptable or applicable to those used in or for EVs. Foundational products include all products utilized on internal combustion engines plus those same products and components that are also included in hybrid powertrains. The following table represents a disaggregation of revenue from contracts with customers by Foundational products and eProducts for the years ended December 31, 2025, 2024, and 2023.

In 2024, the Company reflected a $151 million tax impact of non-deductible impairment of goodwill. In addition, the Company recorded a tax benefit of $107 million related to reductions in certain unrecognized tax benefits and accrued interest for matters where the statute of limitations lapsed and a tax benefit of $36 million related to post Spin-Off restructuring.
In 2023, the Company recognized a tax benefit of $19 million related to the resolution of tax audits and reductions in certain unrecognized tax benefits and accrued interest related to matters for which the statute of limitation had lapsed. In addition, the Company recognized a tax benefit of $50 million in relation to the Spin-Off, a tax benefit of $30 million in relation to various changes in filling positions for prior years, and a tax expense of $79 million in relation to changes in judgment related to the recovery of deferred tax assets, primarily due to the impact of the Spin-Off on the allocation of the Company’s profits across jurisdictions for tax purposes as well as various tax structuring actions and strategies.
A roll forward of the Company’s total gross unrecognized tax benefits is presented below:

The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense and accrued approximately $28 million and $22 million for the payment of interest and penalties at December 31, 2025 and 2024, respectively. For the years ended December 31, 2025, 2024 and 2023, the Company recognized expense related to interest and penalties of $4 million, $5 million and $10 million, respectively. During the year ended December 31, 2024, the Company also recorded a reduction in tax expense of $46 million for previously recorded interest related to matters for which the statute of limitations lapsed.
As of December 31, 2025, approximately $80 million represents the amount that, if recognized, would affect the Company's effective income tax rate in future periods. This amount includes a decrease in U.S. federal income taxes that would occur upon recognition of the state tax benefits and U.S. foreign tax credits included therein.
The Company and/or one of its subsidiaries files income tax returns with the U.S. federal and various state and foreign jurisdictions. In certain tax jurisdictions, the Company may have more than one taxpayer. The Company is no longer subject to income tax examinations by tax authorities in its major tax jurisdictions as follows:

As of December 31, 2025, the Company had non-U.S. net operating loss (“NOL”) deferred tax assets of $235 million, $26 million of which expire at various dates from 2026 through 2045 and $209 million of which have an indefinite life. As of December 31, 2025, the Company had a valuation allowance of $201 million with regards to these deferred tax assets. As of December 31, 2025, certain non-U.S. subsidiaries have tax credit carryforwards of $21 million of which expire at various dates from 2026 to 2035. As of December 31, 2025, the Company had a valuation allowance of $2 million with regards to these deferred tax assets.
As of December 31, 2025, U.S. subsidiaries had net operating loss (“NOL”) deferred tax assets of approximately $39 million, of which $15 million expire at various dates from 2026 through 2044 and $24 million of which have an indefinite life. As of December 31, 2025, the Company had a valuation allowance of $36 million with regard to these deferred tax assets. As of December 31, 2025, certain U.S. subsidiaries have tax credit carryforwards of $85 million of which expire at various dates from 2026 to 2045. As of December 31, 2025, the Company had a valuation allowance of $47 million with regard to these deferred tax assets.
On a quarterly basis, the Company reviews the likelihood that the benefit of its deferred tax assets will be realized and, therefore, the need for valuation allowances. The Company assesses existing deferred tax assets, net operating loss carryforwards and tax credit carryforwards by jurisdiction and expectations of its ability to utilize these tax attributes through a review of past, current, and estimated future taxable income and tax planning strategies. If, based upon the weight of available evidence, it is more-likely-than-not the deferred tax assets will not be realized, a valuation allowance is recorded. Due to recent restructurings, the Company concluded that the weight of the negative evidence outweighs the positive evidence in certain foreign jurisdictions. As a result, the Company believes it is more-likely-than-not that the net deferred tax assets in certain jurisdictions that include entities in France, Spain, U.S., Italy, Turkey, Germany, and China will not be realized in the future.

NOTE 12 GOODWILL AND OTHER INTANGIBLES
Goodwill is the excess of the purchase price over the estimated fair value of identifiable net assets acquired in business combinations. As of December 31, 2025, the Company had four reportable segments and four goodwill reporting units.
2025 Goodwill Analyses
During the first quarter of 2025, as a result of the Company’s plan to exit the charging business, the Company separately allocated the goodwill from its historical reporting unit of Battery & Charging Systems to the battery systems business and to the charging business on a relative fair value basis. The Company estimated the allocated fair values of the businesses from the historical reporting unit based upon the present value of their anticipated future cash flows. The estimated fair value of the charging business was determined using a cost approach. The Company’s determination of fair value involved judgment and the use of estimates and assumptions. During the first quarter of 2025, the relative fair value analysis resulted in an allocation, and subsequent impairment, of $13 million related to the goodwill allocated to the charging business. Refer to Note 2, “Acquisitions and Dispositions,” to the Consolidated Financial Statements for more information.
In conjunction with the goodwill allocation in the first quarter of 2025, the Company performed a quantitative impairment assessment of the Battery & Charging Systems’ goodwill after the impairment of the charging business’ goodwill. Based on this interim impairment test, the Battery & Charging Systems reporting unit had an estimated fair value that exceeded its carrying value, including goodwill, by approximately 18%, resulting in no impairment at that time.
During the fourth quarter of 2025, the Company performed a qualitative analysis on its Turbos & Thermal Technologies and Drivetrain & Morse Systems reporting units and performed a quantitative analysis on its Battery & Charging Systems reporting unit. The goodwill associated with the Company’s PowerDrive Systems reporting unit was fully impaired during the year ended December 31, 2024. The Company’s qualitative assessment on its Turbos & Thermal Technologies and Drivetrain & Morse Systems reporting units indicated it was more-likely-than-not the fair value of these reporting units exceeded the carrying value.
For the quantitative analysis of the Battery & Charging Systems reporting unit, the estimated fair values were determined using an income approach. Under the income approach, fair value is determined based on present value of estimated future cash flows, discounted at an appropriate risk-adjusted rate.
The Company believes the assumptions and estimates used to determine the estimated fair value are reasonable. Different assumptions could materially affect the estimated fair value. The significant assumptions affecting the Company’s 2025 goodwill quantitative impairment review were as follows:
•Discount rates: The Company used a 14% weighted average cost of capital (“WACC”) as the discount rates for future cash flows. The WACC is intended to represent a rate of return that would be expected by a market participant.
•Operating income (loss) margin: The Company used historical and expected operating income (loss) margins, which may vary based on the projection of the reporting unit being evaluated.
•Revenue growth rates: The Company used a global automotive market industry growth rate forecast adjusted to estimate its own market participation for product lines.
99

Table of Contents
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
In addition to the above significant assumptions, the Company noted the following risks to volume and operating income assumptions that could have an impact on the discounted cash flow models:
•The automotive industry is cyclical, and the Company’s results of operations could be adversely affected by industry downturns.
•The automotive industry is evolving, and if the Company does not respond appropriately, its results of operations could be adversely affected.
•The Company is dependent on market segments that use its key products and could be affected by decreasing demand in those segments.
•The Company is subject to risks related to international operations.
During the fourth quarter of 2025, in connection with the preparation of the Company’s annual financial statements, the Company noted deterioration in the forecast for its Battery & Charging Systems business. This deterioration was due to dual sourcing actions by certain customers and electric vehicle adoption delays in North America. As a result, during the fourth quarter of 2025, the Company recorded an incremental impairment charge of $410 million. For the year ended December 31, 2025, the Company recorded total goodwill impairment charges of $423 million related to the Battery & Charging Systems reporting unit.
The goodwill impairment charges related to Battery & Charging Systems represent the difference between carrying value and fair value, meaning the carrying value for this reporting unit now approximates its fair value. The fair value of the Battery & Charging Systems reporting unit’s goodwill is sensitive to differences between estimated and actual cash flows, including changes in the projected revenue, projected operating margin and discount rate used to evaluate the fair value of these assets and market multiples assumptions applied by the Company.
2024 Goodwill Analyses
During the first quarter of 2024, the Company reduced the outlook of its PowerDrive Systems business in response to volatility in actual and expected customer production schedules. This was viewed as a triggering event, and as a result, the Company performed an interim quantitative analysis of the fair value of the PowerDrive Systems reporting unit. Based on this interim impairment test, the PowerDrive Systems reporting unit had an estimated fair value that exceeded its carrying value, including goodwill, by approximately 5%, resulting in no impairment, at that time.
During the third quarter of 2024, as a result of the previously disclosed reportable segment realignment, the Company disaggregated certain entities within one of the Company’s historical goodwill reporting units across two reporting units: Drivetrain & Morse Systems and Battery & Charging Systems. As a result of this change, the Company allocated goodwill to these two reporting units on a relative fair value basis. The Company estimated the fair values of the businesses to be split from the historical reporting unit based upon the present value of their anticipated future cash flows. The Company’s determination of fair value involved judgment and the use of estimates and assumptions. In conjunction with the goodwill allocation, the Company performed a quantitative impairment assessment of the historical reporting units’ goodwill immediately before and after the segment realignment. The quantitative analyses did not result in any impairment charges as the fair value of each reporting unit exceeded its respective carrying value.

Table of Contents
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
During the fourth quarter of 2024, the Company performed a qualitative analysis on two of the reporting units and performed a quantitative analysis on the other two reporting units. For the quantitative analyses, the estimated fair values were determined using an income and market approach. The market approach is based on market multiples (revenue and “EBITDA”, defined as earnings before interest, taxes, depreciation and amortization) and requires an estimate of appropriate multiples based on market data for comparable companies. The market valuation models and other financial ratios used by the Company require certain assumptions and estimates regarding the applicability of those models to the Company’s facts and circumstances.
During the fourth quarter of 2024, in connection with the preparation of the Company’s annual financial statements, the Company noted deterioration in the forecast for its PowerDrive Systems and Battery & Charging Systems businesses. This deterioration was due to further decreases in demand for eProducts as compared to the Company’s expectations as a result of electric vehicle adoption volatility across different regions. This downward revision to the outlooks of these businesses was due to volatility in actual and expected customer production schedules. The Company had made capital investments to support new eProducts business that has been delayed and/or launched with lower-than-expected volumes. As a result, during the fourth quarter of 2024, the Company recorded goodwill impairment charges of $468 million and $109 million related to the PowerDrive Systems and Battery & Charging Systems reporting units, respectively.
With respect to the quantitative analyses performed during the years ended December 31, 2025, 2024 and 2023, future changes in the judgments, assumptions and estimates from those used in acquisition-related valuations and goodwill impairment testing, including discount rates or future operating results and related cash flow projections, could result in significantly different estimates of the fair values in the future. An increase in discount rates, a reduction in projected cash flows or a combination of the two could lead to a reduction in the estimated fair values, which may result in impairment charges that could materially affect the Company’s financial statements in any given year.
A summary of the changes in the carrying amount of goodwill is presented in the following tables. Refer to Note 24, “Reportable Segments and Related Information” for more information.

Notes”) and the 5.000% senior notes due in October 2025 (the “October 2025 Senior Notes”). Pursuant to the tender offers, the Company purchased and extinguished $50 million of the March 2025 Senior Notes and $110 million of the October 2025 Senior Notes. On November 1, 2024, the Company redeemed the remaining $343 million outstanding October 2025 Senior Notes at a make-whole redemption price of 101 percent. The tender offers and redemption resulted in a net gain on debt extinguishment of $10 million, primarily related to the write-off of the remaining unamortized fair value up to the October 2025 Senior Notes. The net gain on debt extinguishment is recorded to Interest expense, net, in the Consolidated Statements of Operations.
In September 2023, the Company purchased and extinguished $438 million of senior notes due in 2025, comprised of $115 million and $323 million face value of its March 2025 and October 2025 Senior Notes, respectively. Total cash consideration paid was $430 million. The Company recorded a gain of approximately $28 million during the year ended December 31, 2023, consisting of an $8 million gain related to a cash settlement below the face value of the 2025 notes and $20 million related to the write-off of a portion of the unamortized fair value step up on the October 2025 Senior Notes from the Delphi Technologies acquisition in 2020 and a portion of the unamortized discount on the March 2025 Senior Notes due in 2025 that was recorded at the time of that note issuance. The gain on extinguishment was recorded to Interest expense, net, in the Consolidated Statement of Operations.
The Company may utilize uncommitted lines of credit for short-term working capital requirements. As of December 31, 2025 and 2024, the Company had $3 million and $61 million, respectively, in borrowings under these facilities, which are classified in Short-term debt in the Consolidated Balance Sheets. The short-term borrowings as of December 31, 2024, primarily relate to a European money market loan with an interest rate of Euribor plus 1.75% that is callable upon immediate notice by either party.
The weighted average interest rate on short-term borrowings outstanding as of December 31, 2025 and 2024 was 0.7% and 4.0%, respectively. The weighted average interest rate on all borrowings outstanding, including the effects of outstanding swaps, as of December 31, 2025 and 2024 was 2.5% and 2.8%, respectively. The following table provides details on Interest expense, net included in the Consolidated Statements of Operations.

Total payments | $ | 3,930 |
Less: unamortized premiums, net of discount | (31) |
Total short and long-term debt | $ | 3,899 |

The Company’s long-term debt includes various covenants, none of which are expected to restrict future operations.
The Company has a $2 billion multi-currency revolving credit facility that allows the Company to increase the facility by $1 billion with bank group approval. This facility matures in September 2028. The credit agreement contains customary events of default and one key financial covenant, which is a debt-to-EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) ratio. The Company was in compliance with the financial covenant at December 31, 2025. At December 31, 2025 and 2024, the Company had no outstanding borrowings under this facility.
The Company’s commercial paper program allows the Company to issue up to $2 billion of short-term, unsecured commercial paper notes under the limits of its multi-currency revolving credit facility. Under this program, the Company may issue notes from time to time and use the proceeds for general corporate purposes. The Company had no outstanding borrowings under this program as of December 31, 2025 and 2024.
The total current combined borrowing capacity under the multi-currency revolving credit facility and commercial paper program cannot exceed $2 billion.
As of December 31, 2025 and 2024, the estimated fair values of the Company’s senior unsecured notes totaled $3,690 million and $3,797 million, respectively. The estimated fair values were $175 million and $257 million lower than carrying value at December 31, 2025 and 2024, respectively. Fair market values of the senior unsecured notes are developed using observable values for similar debt instruments, which are considered Level 2 inputs as defined by ASC Topic 820. The carrying values of the Company’s multi-currency revolving credit facility, commercial paper program and other debt facilities approximate fair value. The fair value estimates do not necessarily reflect the values the Company could realize in the current markets.
The Company had outstanding letters of credit of $36 million and $29 million at December 31, 2025 and 2024, respectively. The letters of credit typically act as guarantees of payment to certain third parties in accordance with specified terms and conditions.

NOTE 16 FAIR VALUE MEASUREMENTS
ASC Topic 820 emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering market participant assumptions in fair value measurements, ASC Topic 820 establishes a fair value hierarchy, which prioritizes the inputs used in measuring fair values as follows:
Level 1: Observable inputs such as quoted prices for identical assets or liabilities in active markets;
Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and
Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.
106

Table of Contents
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Assets and liabilities measured at fair value are based on one or more of the following three valuation techniques noted in ASC Topic 820:
A. Market approach: Prices and other relevant information generated by market transactions involving identical or comparable assets, liabilities or a group of assets or liabilities, such as a business.
B. Cost approach: Amount that would be required to replace the service capacity of an asset (replacement cost).
C. Income approach: Techniques to convert future amounts to a single present amount based upon market expectations (including present value techniques, option-pricing and excess earnings models).

1 Certain assets that are measured at fair value using the NAV per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. These amounts represent investments in commingled and managed funds that have underlying assets in fixed income securities, equity securities, and other assets and the fair values have been estimated using the net asset value of the Company's ownership interest in partners' capital. The Company’s redemption of its investments with the funds is governed by the partnership agreements and subject to approval from the general partners. With the exception of annual distributions in connection with the Company’s deemed tax liability, distributions from each fund will be received as the underlying investments of the funds are liquidated, the timing of which is unknown.

_____________________________
1 A BorgWarner defined benefit plan in the United Kingdom owns an insurance contract that guarantees payment of specified pension liabilities. The Company measures the fair value of the insurance asset by projecting expected future cash flows from the contract and discounting them to present value based on current market rates, including an assessment for non-performance risk of the insurance company. The assumptions used to project expected future cash flows are based on actuarial estimates and are unobservable; therefore, the contract is categorized within Level 3 of the hierarchy.
2 Certain assets that are measured at fair value using the NAV per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. These amounts represent investments in commingled and managed funds that have underlying assets in fixed income securities, equity securities, and other assets.

During the year ended December 31, 2024, the Company recorded asset impairment charges of $69 million related to certain property, plant, and equipment at locations in the Company’s Battery & Charging Systems and PowerDrive Systems reporting segments. Refer to Note 1, “Summary of Significant Accounting Policies,” to the Consolidated Financial Statements for more information.
During the year ended December 31, 2025, the Company recorded investment impairment charges of $16 million. Refer to Note 6, “Other Operating Expense (Income), Net,” to the Consolidated Financial Statements for more information.
NOTE 17 FINANCIAL INSTRUMENTS
The Company’s financial instruments include cash and cash equivalents, marketable securities and accounts receivable. Due to the short-term nature of these instruments, their book value approximates their fair value. The Company’s financial instruments may include long-term debt, investments in equity securities, interest rate and cross-currency swaps, commodity derivative contracts and foreign currency derivative contracts. All derivative contracts are placed with counterparties that have an S&P, or equivalent, investment grade credit rating at the time of the contracts’ placement. An adjustment for non-performance risk is considered in the estimate of fair value in derivative assets based on the counterparty credit default swap (“CDS”) rate. When the Company is in a net derivative liability position, the non-performance risk adjustment is based on its CDS rate. At December 31, 2025 and 2024, the Company had no derivative contracts that contained credit-risk-related contingent features.
Cash Flow Hedges
The Company, at times, uses certain commodity derivative contracts to protect against commodity price changes related to forecasted raw material and component purchases. The Company had no material commodity derivative contracts at December 31, 2025 and 2024.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
The Company manages its interest rate risk by balancing its exposure to fixed and variable rates while attempting to optimize its interest costs. The Company, at times, selectively uses interest rate swaps and options to reduce market value risk associated with changes in interest rates. At December 31, 2025 and 2024, the Company had no outstanding interest rate swaps or options.
The Company uses foreign currency forward and option contracts to protect against exchange rate movements for forecasted cash flows, including capital expenditures, purchases, operating expenses or sales transactions designated in currencies other than the functional currency of the operating unit. Foreign currency derivative contracts require the Company, at a future date, to either buy or sell foreign currency in exchange for the operating units’ local currency.
Effectiveness for cash flow hedges is assessed at the inception of the hedging relationship and quarterly, thereafter. Gains and losses arising from these contracts that are included in the assessment of effectiveness are deferred into accumulated other comprehensive income (loss) (“AOCI”) and reclassified into income as the underlying operating transactions are recognized. These realized gains or losses offset the hedged transaction and are recorded on the same line in the statement of operations. The initial value of any component excluded from the assessment of effectiveness is recognized in income using a systematic and rational method over the life of the hedging instrument. Any difference between the change in fair value of the excluded component and amounts recognized in income under that systematic and rational method is recognized in AOCI.
At December 31, 2025, the following notional amounts related to foreign currency derivative contracts were outstanding, which mature through the December, 2027:

|  | (in millions) |  | Notional Amount 1 |  |
|  | Traded currency |  | Notional in Traded Currency |  | Notional in Approximate U.S. Dollar |  |

Net Investment Hedges
In addition, the Company is also exposed to the risk that adverse changes in foreign currency exchange rates could impact its net investment in non-U.S. subsidiaries.
The Company selectively uses cross-currency swaps to hedge that foreign currency exposure. At December 31, 2025 and 2024, the following cross-currency swap contracts were outstanding and mature through August, 2030:

During the year ended December 31, 2025, the Company unwound $700 million of cross-currency swap contracts originally maturing in July 2027, resulting in a cash outflow of approximately $4 million. The corresponding loss is expected to remain in AOCI until the net investment is sold, completely liquidated or substantially liquidated. Concurrently, the Company executed two U.S. Dollar to Euro cross-currency swap contracts of $500 million maturing in July 2028 and $200 million maturing in August 2030.
In April 2024, the Company terminated its $500 million cross-currency swap contract originally maturing in March 2025, resulting in cash proceeds of $23 million, the corresponding gain is expected to remain in accumulated other comprehensive loss until the net investment is sold, completely liquidated or substantially liquidated. Concurrently, the Company executed a $500 million cross-currency swap contract maturing in March 2029.
In addition, the Company has designated the €1,000 million 1.000% Senior Notes due May 19, 2031, as a net investment hedge of the foreign currency exposure of its investments in certain Euro-denominated subsidiaries. Refer to Note 14, “Debt,” to the Consolidated Financial Statements for more information.
The Company assesses the effectiveness for net investment hedges at the inception of the hedging relationship and quarterly, thereafter. Gains and losses arising from these contracts that are included in the assessment of effectiveness are deferred into foreign currency translation adjustments and only released when the subsidiary being hedged is sold or substantially liquidated. The initial value of any component excluded from the assessment of effectiveness is recognized in income using a systematic and rational method over the life of the hedging instrument. Any difference between the change in fair value of the excluded component and amounts recognized in income under that systematic and rational method is recognized in AOCI.

NOTE 18 RETIREMENT BENEFIT PLANS
The Company sponsors various defined contribution savings plans, primarily in the U.S., that allow employees to contribute a portion of their pre-tax and/or after-tax income in accordance with plan specified guidelines. Under specified conditions, the Company will make contributions to the plans and/or match a percentage of the employee contributions up to certain limits. Total expense related to the defined contribution plans was $44 million, $46 million and $45 million in the years ended December 31, 2025, 2024 and 2023, respectively.
The Company has a number of defined benefit pension plans and other postemployment benefit plans covering eligible salaried and hourly employees and their dependents. The defined pension benefits provided are primarily based on (i) years of service and (ii) average compensation or a monthly retirement benefit amount. The Company provides defined benefit pension plans in Germany, India, Italy, Japan, Mexico, Poland, South Korea, Sweden, Switzerland, Thailand, Turkey, U.K. and the U.S. The other postemployment benefit plans, which provide medical benefits, are unfunded plans. The Company’s U.S. and U.K. defined benefit plans are frozen, and no additional service cost is being accrued. All pension and other postemployment benefit plans in the U.S. have been closed to new employees. The measurement date for all plans is December 31.
In August 2025, the Company executed an amendment to the plan document of one of the Company’s U.S. defined benefit pension plans (“U.S. Pension Plan”) to terminate the plan effective October 31, 2025. The termination of the U.S. Pension Plan is expected to take up to eighteen months to complete. As part of the termination process, the Company expects to settle benefit obligations under the U.S. Pension Plan through a combination of lump sum payments to eligible plan participants and the purchase of a group annuity contract, under which future benefit obligations and administration will be transferred to a third-party insurance company. Such settlements will be funded primarily from plan assets. At December 31, 2025, the projected benefit obligation of the U.S. Pension Plan’s exceeded fair value of plan assets by $4 million under U.S. GAAP.

In December 2024, the Company entered into a second buy-in contract (the first buy-in contract was entered into in 2019) with an insurance company related to its U.K. pension plan. Pursuant to this agreement, the Company liquidated approximately $50 million of pension plan assets to invest in an insurance annuity. At December 31, 2025, the U.K. pension plan had plan assets of $131 million, all held by the insurance company. The projected benefit obligation of the U.K. pension plan at December 31, 2025 was $104 million under U.S. GAAP. The U.K. pension plan was overfunded by $27 million as of December 31, 2025, under U.S. GAAP.

1 The increase in the projected benefit obligation was primarily due to the impact of foreign currency exchange and net periodic pension cost, offset by actuarial gains and benefits paid during the period. The main driver of the actuarial gains was an increase in the weighted average discount rate for the Non-U.S. plans.

The Company’s investment strategy is to maintain actual asset weightings within a preset range of target allocations. The Company believes these ranges represent an appropriate risk profile for the planned benefit payments of the plans based on the timing of the estimated benefit payments. In each asset category, separate portfolios are maintained for additional diversification. Investment managers are retained in each asset category to manage each portfolio against its benchmark. Each investment manager has appropriate investment guidelines. In addition, the entire portfolio is evaluated against a

relevant peer group. The defined benefit pension plans did not hold any Company securities as investments as of December 31, 2025 and 2024. A portion of pension assets is invested in common and commingled trusts.
The Company expects to contribute approximately $25 million into its defined benefit pension plans during 2026. Of the $25 million in projected 2026 contributions, $8 million are contractually obligated, while any remaining payments would be discretionary.
Refer to Note 16, “Fair Value Measurements,” to the Consolidated Financial Statements for more detail surrounding the fair value of each major category of plan assets, as well as the inputs and valuation techniques used to develop the fair value measurements of the plans’ assets at December 31, 2025 and 2024.

The Company's approach to establishing the discount rate is based upon the market yields of high-quality corporate bonds, with appropriate consideration of each plan's defined benefit payment terms and duration of the liabilities. In determining the discount rate, the Company utilizes a full-yield approach in the estimation of service and interest components by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows.
The Company determines its expected return on plan assets assumptions by evaluating estimates of future market returns and each plans’ asset allocation. The Company also considers the impact of active management of the plans’ invested assets.
The estimated future benefit payments for the pension and other postemployment benefits are as follows:

|  | Pension benefits |  | Other postemployment benefits
(in millions) |  |  |  |  |
Year |  | U.S. |  | Non-U.S. |

NOTE 19 STOCK-BASED COMPENSATION
The Company has granted restricted common stock and restricted stock units (collectively, “restricted stock”) and performance stock units as long-term incentive awards to employees and non-employee directors under the BorgWarner Inc. 2018 Stock Incentive Plan, as amended (“2018 Plan”) and the BorgWarner Inc. 2023 Stock Incentive Plan (“2023 Plan”). The Company’s Board of Directors adopted the 2023 Plan as a replacement to the 2018 Plan in February 2023, and the Company’s stockholders approved the 2023 Plan at the annual meeting of stockholders on April 26, 2023. The 2023 Plan authorizes the issuance of a total of 11.3 million shares and approximately 3.9 million shares were available for future issuance as of December 31, 2025.
Restricted Stock: The value of restricted stock is determined by the market value of the Company’s common stock at the date of grant. In 2025, restricted stock in the amount of 1.0 million shares were granted to employees and less than 0.1 million shares were granted to non-employee directors. The value of the awards is recognized as compensation expense ratably over the restriction periods, generally two or three years. As of December 31, 2025, there was $30 million of unrecognized compensation expense related to restricted stock that will be recognized over a weighted average period of approximately 1.6 years.
Restricted stock compensation expense from continuing operations recorded in the Consolidated Statements of Operations is as follows:

NOTE 21 CONTINGENCIES
In the normal course of business, the Company is party to various commercial and legal claims, actions and complaints, including matters involving warranty claims, intellectual property claims, governmental investigations and related proceedings, general liability and other risks. It is not possible to predict with certainty whether the Company will ultimately be successful in any of these commercial and legal matters or what the impact might be. The Company does not believe that adverse outcomes in any of these commercial and legal claims, actions and complaints are reasonably likely to have a material adverse effect on the Company’s results of operations, financial position or cash flows. An adverse outcome could, nonetheless, be material to the results of operations or cash flows as the ultimate resolutions of these matters are inherently unpredictable.
On September 19, 2024, the Company commenced a lawsuit against PHINIA, seeking to recover from PHINIA approximately $120 million of value added tax (“VAT”) refunds that PHINIA received or expects to
125

Table of Contents
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
receive from governmental agencies as well as damages and interest. These refunds consisted of VAT paid by the Company in periods prior to or directly related to the Spin-Off that established PHINIA as an independent company. PHINIA responded to the lawsuit and also asserted counterclaims against the Company. On October 15, 2025, the Company entered into a settlement agreement (the “Settlement Agreement”) with PHINIA, pursuant to which PHINIA agreed to pay the Company $78 million, resolving the lawsuit and certain other matters relating to the Spin-Off. In connection with the Settlement Agreement, the Company and PHINIA also entered into an amended and restated tax matters agreement that, among other things, limits the Company’s responsibility to certain defined tax obligations. As a result, the Company recorded a net charge of $40 million during the year ended December 31, 2025, for the reduction of VAT-related receivables, the elimination of certain Company liabilities under the amended and restated tax matters agreement and related legal fees, which is included in Other operating expense, net in the Company’s Consolidated Statements of Operations. As of December 31, 2025, after giving effect to the Settlement Agreement and the $31 million payment received during the fourth quarter of 2025, the Company had assets related to these VAT refunds of approximately $47 million in Receivables, net in the Company’s Consolidated Balance Sheet.
Environmental
The Company and certain of its current and former direct and indirect corporate predecessors, subsidiaries and divisions have been identified by the United States Environmental Protection Agency and certain local environmental agencies and private parties as potentially responsible parties (“PRPs”) at various hazardous waste disposal sites under the Comprehensive Environmental Response, Compensation and Liability Act (“Superfund”) and equivalent state or local laws and, as such, may have been liable for the cost of clean-up and other remedial activities at 16 and 17 such sites as of December 31, 2025 and 2024, respectively. Responsibility for clean-up and other remedial activities at a Superfund site is typically shared among PRPs based on an allocation formula.
The Company believes that none of these matters, individually or in the aggregate, will have a material adverse effect on its results of operations, financial position or cash flows. Generally, this is because either the estimates of the maximum potential liability at a site are not material or the liability will be shared with other PRPs, although no assurance can be given with respect to the ultimate outcome of any such matter.
The Company had an accrual for environmental liabilities of $6 million and $5 million as of December 31, 2025 and 2024, respectively, included in Other current and Other non-current liabilities in the Consolidated Balance Sheets. As of December 31, 2025, this accrual, which relates to four of the sites, is based on information available to the Company (which, in most cases, includes an estimate of allocation of liability among PRPs; the probability that other PRPs, many of which are large, solvent public companies, will fully pay the cost apportioned to them; currently available information from PRPs and/or federal or local environmental agencies concerning the scope of contamination and estimated remediation and consulting costs; and remediation alternatives). Clean-up and other remedial activities are complete or nearing completion at the other 12 sites, for which there was no accrual as of December 31, 2025.
NOTE 22 LEASES AND COMMITMENTS
The Company’s lease agreements primarily consist of real estate property, such as manufacturing facilities, warehouses and office buildings, in addition to personal property, such as vehicles, manufacturing and information technology equipment. The Company determines whether a contract is or contains a lease at contract inception. The majority of the Company’s lease arrangements are comprised of fixed payments, and a limited number of these arrangements include a variable payment component

based on certain index fluctuations. As of December 31, 2025, a significant portion of the Company’s leases were classified as operating leases.
Generally, the Company’s operating leases have renewal options that extend the lease terms, and some include options to terminate the agreement or purchase the leased asset. The amortizable life of these assets is the lesser of its useful life or the lease term, including renewal periods reasonably assured of being exercised at lease inception.
All leases with an initial term of 12 months or less without an option to extend or purchase the underlying asset that the Company is reasonably certain to exercise (“short-term leases”) are not recorded on the Consolidated Balance Sheets, and lease expense is recognized on a straight-line basis over the lease term.
The following table presents the lease assets and lease liabilities as of December 31, 2025 and 2024:

In the years ended December 31, 2025, 2024 and 2023, the Company recorded operating lease expense of $45 million, $41 million and $33 million, respectively.
In the years ended December 31, 2025, 2024 and 2023, the operating cash flows for operating leases were $44 million, $38 million and $33 million, respectively.
In the years ended December 31, 2025, 2024 and 2023, the Company recorded short-term lease costs of $26 million, $24 million and $29 million, respectively.
Finance lease costs and related cash flows were immaterial for the periods presented.
ASC Topic 842, “Leases”, requires that the rate implicit in the lease be used if readily determinable. Generally, implicit rates are not readily determinable in the Company’s agreements, so the incremental borrowing rate is used instead for such lease arrangements. The incremental borrowing rates are determined using rates specific to the term of the lease, economic environments where lease activity is concentrated, value of lease portfolio, and assuming full collateralization of the loans. The following table presents the terms and discount rates:

| December 31,
| 2025 |  | 2024

Operating leases | 8 |  | 8
Finance leases | 7 |  | 7

Finance leases | 6.5 | % |  | 6.3 | %

NOTE 23 EARNINGS PER SHARE
The Company presents both basic and diluted earnings per share of common stock (“EPS”) amounts. Basic EPS is calculated by dividing net earnings attributable to BorgWarner Inc. by the weighted average shares of common stock outstanding during the reporting period. Diluted EPS is calculated by dividing net earnings attributable to BorgWarner Inc. by the weighted average shares of common stock and common stock equivalents outstanding during the reporting period.
The dilutive impact of stock-based compensation is calculated using the treasury stock method. The treasury stock method assumes that the Company uses the assumed proceeds from the exercise of awards to repurchase common stock at the average market price during the period. The assumed
128

Table of Contents
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
proceeds under the treasury stock method include the purchase price that the grantee will pay in the future and compensation cost for future service that the Company has not yet recognized. The dilutive effects of performance-based stock awards described in Note 19, “Stock-Based Compensation,” to the Consolidated Financial Statements are included in the computation of diluted earnings per share at the level the related performance criteria are met through the respective balance sheet date. There were 1.3 million, 0.9 million and 0.7 million performance stock units excluded from the computation of the diluted earnings per share for the years ended December 31, 2025, 2024 and 2023, respectively. These units were excluded because the related performance criteria had not been met as of the balance sheet dates.
The following table reconciles the numerators and denominators used to calculate basic and diluted earnings per share of common stock:

Segment Adjusted Operating Income (Loss) is the measure of segment income or loss used by the Company. Segment Adjusted Operating Income (Loss) is comprised of operating income for the Company’s reportable segments adjusted to exclude restructuring, merger, acquisition and divestiture expense, intangible asset amortization expense, impairment charges and other items not reflective of ongoing operating income or loss. The Company believes Segment Adjusted Operating Income (Loss) is most reflective of the operational profitability or loss of its reportable segments.
The Company’s CODM uses Segment Adjusted Operating Income (Loss) and the expenses disclosed below to assess the performance of its reportable segments. The CODM uses this information to assist with decisions about future growth, capital investments and cost reduction initiatives by reviewing trends in the business, monitoring variances to historical results and previously forecasted information and performing other analytical comparisons.
The following tables show net sales, segment expenses, Segment Adjusted Operating Income (Loss) and other segment information for the Company’s reportable segments.

In connection with the Spin-Off, the Company entered into a transition services agreement through which the Company and PHINIA provided certain services to each other following the Spin-Off. These services were related to information technology, human resources, finance, facilities, procurement, sales, intellectual property and engineering. In December 2024, the Company and PHINIA executed an amendment to the original transition services agreement to extend certain engineering services until September 30, 2025. The transition services agreement expired and all related services ended on September 30, 2025. The combined impact of these services is reported in results of continuing operations in the Consolidated Financial Statements. During the year ended December 31, 2025, there were no activities related to those services. During the year ended December 31, 2024 and 2023, the Company provided services at a cost of $7 million and $13 million to PHINIA, respectively, and PHINIA provided services at a cost of $2 million and $3 million to the Company, respectively.
The Company incurred $31 million and $132 million of costs relating to the Spin-Off during the year ended December 31, 2024 and 2023, respectively, which are reflected within Net loss from discontinued operations in the Company’s Consolidated Statements of Operations. Spin-Off costs are primarily comprised of professional fees and costs to separate certain operational activities, including costs to separate information technology systems which substantially concluded as of December 31, 2024.

Item 9A. Controls and Procedures
Disclosure Controls and Procedures
A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered

relative to costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. However, the Company’s disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives.
The Company has adopted and maintains disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed in the reports filed or submitted under the Exchange Act, such as this report, is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission. The Company’s disclosure controls and procedures are also designed to provide reasonable assurance that such information is accumulated and communicated to management, as appropriate, to allow timely decisions regarding required disclosure. As required under Exchange Act Rule 13a-15, the Company’s management, including the Chief Executive Officer and Chief Financial Officer, has conducted an evaluation of the effectiveness of disclosure controls and procedures as of December 31, 2025, the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures are effective at the reasonable assurance level.
Management’s Report on Internal Control Over Financial Reporting

Based on the assessment, management concluded that, as of December 31, 2025, the Company’s internal control over financial reporting was effective based on those criteria.
