Organization, Consolidation and Presentation of Financial Statements [Abstract]  
INTRODUCTION
INTRODUCTION
The accompanying Consolidated Financial Statements and notes present the consolidated statements of operations, cash flows, comprehensive income and stockholders’ equity and balance sheets of PHINIA Inc. (PHINIA or the Company). PHINIA is a leader in the development, design and manufacture of integrated components and systems that are designed to optimize performance, enhance efficiency and reduce emissions in combustion and hybrid propulsion for commercial vehicles and industrial applications (medium-duty and heavy-duty trucks, buses and other off-highway construction, marine, agricultural and industrial applications), light commercial vehicles (vans and trucks) and light passenger vehicles (passenger cars, mini-vans, cross-overs and sport-utility vehicles). The Company is a global supplier to most major original equipment manufacturers (OEMs) seeking to meet or exceed evolving and increasingly stringent global regulatory requirements and satisfy consumer demands for an enhanced user experience. Additionally, the Company offers a wide range of original equipment service (OES) solutions and remanufactured products as well as an expanded range of products for the independent (non-OEM) aftermarket.
Transition to Standalone Company
On July 3, 2023, PHINIA became an independent publicly traded company as a result of the legal and structural separation of the Fuel Systems and Aftermarket businesses from BorgWarner Inc. (BorgWarner or Former Parent). The separation was completed in the form of a distribution of the outstanding common stock of PHINIA to holders of record of common stock of BorgWarner on a pro rata basis (the Spin-Off). In connection with the Spin-Off, we entered into an agreement with the Former Parent which governs the Company’s and the Former Parent’s respective rights, responsibilities and obligations after the distribution with respect to taxes for any tax period ending on or before the distribution date, as well as tax periods beginning before and ending after the distribution date (Tax Matters Agreement).

Accounting Policies [Abstract]  
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
The following paragraphs briefly describe the Company’s significant accounting policies.
Basis of presentation Prior to the Spin-Off on July 3, 2023, the historical financial statements of PHINIA were prepared on a stand-alone combined basis and were derived from BorgWarner’s consolidated financial statements and accounting records as if the Fuel Systems and Aftermarket businesses of BorgWarner had been part of PHINIA for all periods presented. Accordingly, for periods prior to July 3, 2023, our financial statements are presented on a combined basis and for the periods subsequent to July 3, 2023 are presented on a consolidated basis (all periods hereinafter are referred to as “consolidated financial statements”). The Company’s Consolidated Financial Statements were prepared in accordance with accounting principles in the United States of America (U.S. GAAP) pursuant to the rules and regulations of the Securities and Exchange Commission (SEC).
Management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and accompanying notes, as well as amounts of revenues and expenses reported during the periods covered by those financial statements and accompanying notes. The Consolidated Financial Statements may not be indicative of the Company’s future performance and do not necessarily reflect what the financial position, results of operations, and cash flows would have been had it operated as a standalone company during the periods presented prior to the Spin-Off.
The Consolidated Statements of Operations include all revenues and costs directly attributable to the Company, including costs for facilities, functions, and services utilized. Costs for certain centralized functions and programs provided and administered by BorgWarner were charged directly to the Company prior to Spin-Off. These centralized functions and programs included, but were not limited to research and development and information technology.
A portion of BorgWarner’s total corporate expenses were allocated to the Company for services rendered by BorgWarner prior to the Spin-Off. These expenses included the cost of corporate functions and resources, including, but not limited to, executive management, finance, accounting, legal, human resources, research and development and sales. Additionally, a portion of the Company’s corporate expenses were allocated to BorgWarner for charges incurred related to subsidiaries of BorgWarner historically supported by the Company, primarily related to information technology. These expenses were allocated based on direct usage when identifiable or, when not directly identifiable, on the basis of proportional net revenues, legal entities, headcount or weighted-square footage, as applicable. The Company considers the basis on which the expenses have been allocated to reasonably reflect the utilization of services provided to, or the benefit received by, both the Company and BorgWarner during the periods presented. However, the allocations may not reflect the expenses the Company would have incurred if the Company had been a standalone company for the periods presented prior to July 3, 2023. The year ended December 31, 2023 included net corporate allocation expenses incurred prior to the Spin-Off totaling $89 million. Corporate allocation expenses were primarily included in Selling, general and administrative expenses.
Use of estimates The preparation of financial statements in conformity with U.S. 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 with a controlling financial interest. All inter-company balances and transactions have been eliminated in consolidation.
Joint venture and equity securities The Company has an investment in one unconsolidated joint venture: Delphi-TVS Diesel Systems Ltd (D-TVS), of which the Company owns 52.5%. This joint venture is a non-controlled affiliate in which the Company exercises significant influence but does not have a controlling financial interest and, therefore, is accounted for under the equity method. Although the Company is the majority owner, it does not have the ability to control significant decisions or management of the entity. The Company evaluated this investment under Accounting Standards Codification (ASC) Topic 810 and based on the following factors the Company does
not have the power to control the significant decisions of the entity and therefore does not have a controlling financial interest.
•Both partners appoint a managing director and these directors jointly manage all of the affairs of D-TVS, subject to supervision by the board of directors;
•The Company has only a 36% representation on the board of directors; and
•The construct of the board of directors prevents either party from having power/control as described in ASC Topic 810 because both parties lack the ability to directly and/or indirectly control governance and management of D-TVS through either its ownership interest or the board representation.
Generally, under the equity method, the Company’s original investment is recorded at cost and subsequently adjusted by the Company’s share of equity in income or losses. The carrying value of the Company’s investment was $60 million and $51 million as of December 31, 2025 and 2024, respectively. 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 this non-controlled affiliate 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.
Interests in privately held companies that do not have readily determinable fair values are accounted for using the measurement alternative under ASC Topic 321, 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.
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 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 the term of the arrangement and recognizes revenue based on the estimated amount of consideration to be received from these arrangements.
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. Cash and cash equivalents are primarily held in foreign locations. 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.
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.
Sales of receivables are accounted for in accordance with the ASC Topic 860. Agreements which result in true sales of the transferred receivables, as defined in ASC Topic 860, which occur when receivables are transferred to a third party without recourse to the Company, are excluded from amounts reported in the Consolidated Balance Sheets. Cash proceeds received from such sales are included in operating cash flows. The expenses associated with receivables factoring are recorded in the Consolidated Statements of Operations within interest expense. Refer to Note 8, “Receivables, Net,” to the Consolidated Financial Statements for more information.
Inventories Inventory is measured using first-in, first-out (FIFO) or average-cost methods at the lower of cost or net realizable value. Refer to Note 9, “Inventories,” to the Consolidated Financial Statements for more information.
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 fifteen to forty years, and useful lives for machinery and equipment range from three to twelve 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 amortizable intangible assets, when events and circumstances warrant such a review under 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 recorded for the amount by which the carrying value of the long-lived asset exceeds its fair value.
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 (1) an assessment as to whether an adverse event or circumstance has triggered the need for an impairment review; (2) undiscounted future cash flows generated by the asset; and (3) fair valuation of the asset.
Goodwill and other indefinite-lived intangible assets During the fourth quarter of each year, the Company qualitatively assesses its goodwill. This 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. In addition, the Company also tests goodwill in between annual test dates if an event occurs or circumstances change that could more-likely-than-not reduce the fair value of a reporting unit below its carrying value.
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 expenses are incurred.
Similar to goodwill, the Company can elect to perform the impairment test for indefinite-lived intangibles other than goodwill (trade names) using a qualitative analysis, considering similar factors as outlined in the goodwill discussion in order to determine if it is more-likely-than-not that the fair value of the intangibles are 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 for more information.
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, in certain cases, initial customer claims exceed the amount accrued. Facts may become known related to these claims that may result in additional losses that could be material to the Company’s results of operations or cash flows. The product warranty accrual is allocated to Other current liabilities and Other 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 and are not material.
Refer to Note 20, “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 and 2024, the Company recorded $8 million and $7 million in Other non-current liabilities, respectively, in the Company’s Consolidated Balance Sheets. During the years ended December 31, 2025, 2024 and 2023, the Company recorded $24 million, $28 million and $21 million of government grant-related credits in Selling, general and administrative expenses, respectively, and $5 million, $2 million and $1 million in 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 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 consider mitigating such risks through various methods, including financial derivatives. The majority of 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 16, “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 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 19, “Accumulated Other Comprehensive Loss,” to the Consolidated Financial Statements for more information.
Pensions  The Company’s defined benefit pension plans are accounted for in accordance with ASC Topic 715. Disability early retirement benefits are accounted for in accordance with ASC Topic 712.
Pension 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 U.S. 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 17, “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 they are entitled to 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 accrued over the required service period.
Income taxes The Company accounts for income taxes in accordance ASC Topic 740 (ASC 740). Income taxes as presented in the Company’s Consolidated Financial Statements have been allocated in a manner that is systematic, rational, and consistent with the broad principles of ASC 740. Prior to Spin-Off, the Company’s operations have been included in the Former Parent’s U.S. federal consolidated tax return, certain foreign tax returns, and certain state tax returns.
In accordance with ASC 740, 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.
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 credits 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.

ACQUISITION ACQUISITION
On August 1, 2025, the Company acquired 100% of Swedish Electromagnet Invest AB (SEM) for $47 million, comprised of $15 million of cash consideration and $32 million cash used to extinguish debt assumed through the acquisition. SEM is part of the Fuel Systems segment, and is a provider of advanced natural gas, hydrogen and other alternative fuel ignition systems, injector stators and linear position sensors.
The SEM acquisition was accounted for as a business combination, with the purchase price, net of cash acquired, allocated on a preliminary basis as of August 1, 2025. The preliminary allocation of the purchase price to acquired assets and liabilities assumed, including the residual amount recognized as goodwill, is based upon estimated information and is subject to change within the measurement period. The measurement period is a period not to exceed one year from the acquisition date during which the Company may adjust estimated or provisional amounts recorded during purchase accounting if new information is obtained about facts and circumstances that existed as of the acquisition date that, if known, would have resulted in revised estimated values of those assets or liabilities as of that date. Measurement period adjustments are recorded in the period identified. The Company is in the process of finalizing all purchase accounting adjustments. Certain estimated values for the acquisition, including goodwill, intangible assets and deferred taxes are not yet finalized, and the preliminary purchase price allocations are subject to change as the Company completes its analysis of the fair value at the date of acquisition. The final valuation of assets acquired and liabilities assumed may be materially different from the estimated values shown below.
The following table summarizes the preliminary fair values of the assets acquired and liabilities assumed as of the date of acquisition:

____________
1 Total purchase consideration excludes cash paid of $32 million used to extinguish debt assumed through the acquisition.
2 Goodwill is not deductible for tax purposes.
The preliminary valuation of intangible assets consisted of the following assets subject to amortization (in millions, except weighted-average useful life):
Fair ValueWeighted-Average Useful LifeValuation MethodologyKey Assumptions
Customer relationships$18 12 yearsMulti-period excess earningsDiscount rate, customer attrition rate
Patented and unpatented technology96 yearsRelief-from-royaltyRoyalty rate, discount rate, obsolescence factor
The purchase price, net of cash acquired, was allocated based on the estimated fair value of the assets acquired and liabilities assumed at the date of acquisition with the excess purchase price recorded as goodwill, all of which was allocated to the Fuel Systems segment. The goodwill is primarily the result of expected synergies as well as enhancing the Company’s product portfolio and strategy, enabling the Company to explore adjacent market opportunities to increase Fuel Systems sales globally. Amortization expense of purchased intangible assets is primarily recognized on a straight-line basis.

REVENUE FROM CONTRACTS WITH CUSTOMERS REVENUE FROM CONTRACTS WITH CUSTOMERS
The Company manufactures and sells products and solutions, primarily to OEMs of commercial vehicle, industrial applications and light 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.
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. As of December 31, 2025, the balance of contract liabilities was $17 million, of which $7 million was reflected in Other current liabilities and $10 million was reflected as Other non-current liabilities. As of December 31, 2024, the balance of contract liabilities was $7 million, of which $3 million was reflected in Other current liabilities and $4 million was reflected as Other non-current liabilities. 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 following table represents a disaggregation of revenue from contracts with customers by reportable segment and region for the years ended December 31, 2025, 2024, and 2023.

Restructuring and Related Activities [Abstract]  
RESTRUCTURING RESTRUCTURING
The Company’s restructuring activities are undertaken as necessary to execute the Company’s strategy and streamline operations, consolidate and take advantage of available capacity and resources, and ultimately achieve net cost reductions. During the year ended December 31, 2025, the Company has implemented actions as part of a strategic effort to align its legacy infrastructure with current business needs and reduce costs in response to ongoing industry headwinds. Beginning in 2025 and continuing through 2027, the Company anticipates incurring approximately $35 million in restructuring charges under these initiatives, with estimated annual savings of $25 million once fully implemented.
The Company’s restructuring expenses consist primarily of employee termination benefits (principally severance and/or other termination benefits) and other costs, which are primarily professional fees and costs related to equipment moves.
The following table displays a roll forward of the restructuring liability recorded within the Company’s Consolidated Balance Sheets and the related cash flow activity:

During the years ended December 31, 2025, 2024 and 2023, the Company recorded $17 million, $14 million and $12 million of restructuring costs for individually-approved restructuring actions that primarily related to reductions in headcount in the Fuel Systems segment and aligning its legacy infrastructure with current business needs.
Estimates of restructuring expense are based on information available at the time such charges are recorded. Due to the inherent uncertainty involved in estimating restructuring expenses, actual amounts paid for such activities may differ from amounts initially recorded. Accordingly, the Company may record revisions of previous estimates by adjusting previously established accruals.
The Company will recognize restructuring expense associated with any future actions at the time they are approved and become probable or are incurred. Any future actions could result in significant restructuring expense and cash payments.

The provision for income taxes resulted in an effective tax rate of approximately 34%, 58% and 50% for the years ended December 31, 2025, 2024 and 2023, respectively.
The Company’s tax rate is affected by the tax laws and rates of the U.S. and other jurisdictions in which the Company operates, the relative amount of income earned by jurisdiction and the relative amount of losses or income for which no tax benefit or expense was recognized due to a valuation allowance.
The Company’s effective tax rate was impacted beneficially by certain entities in China with the High and New Technology Enterprise (HNTE) status. The income tax benefit for HNTE status was approximately $6 million, $5 million and $6 million for the years ended December 31, 2025, 2024 and 2023, respectively. HNTE status is granted for three-year periods, and the Company seeks to renew such status on a regular basis.

In 2025, the Company recognized discrete tax benefits of $11 million related to unremitted earnings as a result of a favorable change in withholding tax rates and favorable provision to return adjustments of $21 million in various jurisdictions, partially offset by an increase in pre-Spin-Off and post-Spin-off uncertain tax positions of $21 million and $5 million, respectively.
In 2024, the Company recognized discrete tax expense of $21 million related to the establishment of a valuation allowance on its Polish operations as a result of the changes in judgment related to the recovery of its deferred tax assets. This expense was fully offset by a discrete tax benefit related to unremitted earnings as a result of change in structure and favorable provision to return adjustments in various jurisdictions.
In 2023, the Company recognized discrete tax benefits of $7 million, primarily due to certain unrecognized tax benefits and accrued interest related to a matter for which the statute of limitations had lapsed.
The Company recognizes taxes due under the Global Intangible Low-Taxed Income (GILTI) provision as a current period expense.

The Company and/or one of its subsidiaries file income tax returns in the U.S. federal, various state jurisdictions and various foreign jurisdictions. In certain tax jurisdictions, the Company may have more than one taxpayer. The PHINIA U.S. group filed its first U.S. federal return for the tax year 2023 in 2024; therefore, tax years 2023 and 2024 are the only open periods subject to Internal Revenue Service (IRS) audit. 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, certain non-U.S. operations had net operating loss carryforwards totaling $652 million, available to offset future taxable income. These carryforwards are subject to expiration at various dates from 2026 through 2044. The Company has a valuation allowance against $641 million of these non-U.S. net operating loss carryforwards.
The Company reviews the likelihood that the benefit of its deferred tax assets will be realized and, therefore, the need for valuation allowances on a quarterly basis. 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 foreign jurisdictions that include entities in Luxembourg, Poland, and certain deferred tax assets in the United Kingdom will not be realized in the future.

As of December 31, 2025, the Company recorded deferred tax liabilities of $46 million with respect to foreign unremitted earnings. The Company did not provide deferred tax liabilities with respect to certain book versus tax basis differences not represented by undistributed earnings of approximately $430 million as of December 31, 2025, because the Company continues to assert indefinite reinvestment of these basis differences. These basis differences would become taxable upon the sale or liquidation of the foreign subsidiaries. Based on the Company's structure, it is impracticable to determine the unrecognized deferred tax liability on these earnings. Actual tax liability, if any, would be dependent on circumstances existing when a repatriation, sale, or liquidation occurs.

Factoring
The Company has arrangements with various financial institutions to sell eligible trade receivables from certain customers in North America and Europe. These arrangements can be terminated at any time subject to prior written notice. The receivables under these arrangements are sold without recourse by the Company and are, therefore, accounted for as true sales. During the years ended December 31, 2025, 2024 and 2023, the Company sold $162 million, $122 million and $152 million of receivables, respectively, under these arrangements. Additionally, during the
same periods, expenses of $6 million, $6 million and $9 million, respectively, were recognized within interest expense.

Goodwill and Intangible Assets Disclosure [Abstract]  
GOODWILL AND OTHER INTANGIBLES GOODWILL AND OTHER INTANGIBLES
The Company’s goodwill is tested for impairment annually in the fourth quarter for all reporting units, and more frequently if events or circumstances warrant such a review. The Company performed quantitative impairment testing during the fourth quarter of 2025. The estimated fair value was determined using a combined 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.
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 primary assumptions affecting the Company’s 2025 goodwill quantitative impairment review are as follows:
•Discount rates: The Company used 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.
•EBITDA margins: The Company used historical and expected EBITDA margins, which may vary based on the projections 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.
•Market multiples: The Company used appropriate multiples based on market data for comparable companies.
In addition to the above primary assumptions, the Company notes 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.
The results of the impairment testing performed indicated that the estimated fair value of the Fuel Systems and Aftermarket reporting units exceeded their carrying values by considerable amounts. It was determined that the estimated fair value of each reporting unit exceeded its respective carrying value and as such, the Company’s goodwill was not considered impaired as of the fourth quarter of 2025.
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. The Company has determined that each of the reportable segments is also a reporting unit. Refer to Note 24, “Reportable Segments and Related Information” for more information.

PRODUCT WARRANTY

Product Warranties Disclosures [Abstract]  
PRODUCT WARRANTY PRODUCT WARRANTY
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 the Company believes it is probable that a loss will be incurred and the amount can be reasonably estimated. See Note 20, “Contingencies”, for further discussion on the Company’s quarterly process for accruals relating to commercial and legal matters. Management believes that the warranty accrual is appropriate; however, in certain cases, initial customer claims exceed the amount accrued. Facts may become known related to these claims that may result in additional losses that could be material to the Company’s results of operations or cash flows. The Company’s warranty provisions are primarily included in Cost of sales in the Consolidated Statements of Operations. The product warranty accrual is allocated to Other current liabilities and Other non-current liabilities in the Consolidated Balance Sheets.

Credit Agreement
On July 3, 2023, the Company entered into a $1.225 billion Credit Agreement (as amended, the Credit Agreement) consisting of a $500 million revolving credit facility (the Revolving Facility), a $300 million Term Loan A Facility (the Term Loan A Facility) and a $425 million Term Loan B Facility (the Term Loan B Facility; together with the Revolving Facility and the Term Loan A Facility, collectively, the Facilities) in connection with the Spin-Off that occurred on the same date, maturing on July 3, 2028. The Credit Agreement contains customary covenants relating to the Company and its subsidiaries concerning, among other things, investments, dispositions of assets, indebtedness, liens on assets, and dividends and other distributions. The Credit Agreement also contains financial covenants related to the total net leverage ratio as discussed below and the consolidated interest coverage ratio of the Company, determined as of the end of each fiscal quarter, to be at least 3.00 to 1.00. The Term Loan B Facility was fully repaid in connection with the issuance of the 6.75% Senior Secured Notes due 2029 on April 4, 2024, as discussed below. The Term Loan A Facility was fully repaid in connection with the issuance of the 6.625% Senior Notes due 2032 on September 17, 2024, as discussed below.
On April 4, 2024, the Company, as borrower, and certain subsidiaries of the Company, each acting as guarantors, entered into Amendment No. 1 to the Credit Agreement (the Credit Agreement Amendment No. 1). The Credit Agreement Amendment No. 1, among other things, modified certain covenants in the Credit Agreement to be more favorable to the Company, and increased the total net leverage ratio required to be satisfied under the Company’s financial covenant from 3.00:1.00 to 3.25:1.00 (subject to a step-up to 3.75:1.00 in connection with a qualifying acquisition for the fiscal quarter when such qualifying acquisition is consummated and the following three fiscal quarters).
On September 17, 2024, the Company, as borrower, and certain subsidiaries of the Company, each acting as guarantors, entered into Amendment No. 2 to the Credit Agreement (the Credit Agreement Amendment No. 2). The Credit Agreement Amendment No. 2, among other things, (i) reduced the applicable margin with respect to the loans under the Revolving Facility and (ii) modified certain covenants in the Credit Agreement.
The Company utilizes its committed revolving credit facility for short-term working capital requirements, which are reported in Short-term borrowings and current portion of long-term debt on the Consolidated Balance Sheets. As of December 31, 2025 and 2024 the Company had no outstanding borrowings under the Revolving Facility, and availability of $500 million and $499 million, respectively.
Senior Secured Notes due 2029
On April 4, 2024, the Company issued $525 million aggregate principal amount of 6.75% Senior Secured Notes due 2029 (the 2029 Notes) pursuant to an indenture among the Company, as issuer, certain subsidiaries of the Company named as guarantors, and U.S. Bank Trust Company, National Association, as trustee and collateral agent. The 2029 Notes were sold to investors at 100% plus accrued interest, if any, from April 4, 2024 in a private transaction exempt from the registration requirements of the Securities Act. The net proceeds of the offering of the 2029 Notes were used to repay all of the Company’s outstanding borrowings and accrued interest under the Term Loan B Facility and the Revolving Facility and to pay fees and expenses in connection with the offering. During the second quarter of 2024, the Company recorded a non-cash pre-tax loss on extinguishment of $20 million related to the difference between the repayment amount and net carrying amount of the Term Loan B Facility, which is included in the Interest expense line item on the Consolidated Statements of Operations.
The 2029 Notes bear interest at a rate of 6.75% per annum. Interest on the 2029 Notes is payable semiannually on April 15 and October 15 of each year, commencing on October 15, 2024. The 2029 Notes will mature on April 15, 2029.
The 2029 Notes are senior secured obligations of the Company and are jointly and severally, fully and unconditionally, guaranteed on a senior secured basis by certain of the Company’s existing and future direct and indirect domestic restricted subsidiaries that incur or guarantee indebtedness under the Facilities or other qualifying indebtedness that, in the aggregate, exceeds $25 million, including the 2032 Notes (as defined below). The 2029 Notes and the guarantees are secured by a first-priority security interest in substantially all of the Company’s and the guarantors’ assets, subject to certain excluded assets, exceptions and permitted liens, which security interest ranks equally with the first-priority security interest securing the Facilities.
Senior Unsecured Notes due 2032
On September 17, 2024, the Company issued $450 million aggregate principal amount of 6.625% Senior Notes due 2032 (the 2032 Notes) pursuant to an indenture among the Company, as issuer, certain subsidiaries of the Company named as guarantors, and U.S. Bank Trust Company, National Association, as trustee. The 2032 Notes were sold to investors at 100% plus accrued interest, if any, from September 17, 2024 in a private transaction exempt from the registration requirements of the Securities Act of 1933, as amended (the Securities Act). The net proceeds of the offering of the 2032 Notes were used to repay all of the Company’s outstanding borrowings under the Term Loan A Facility, to pay fees and expenses in connection with the offering, and for general corporate purposes. During the third quarter of 2024, the Company recorded a non-cash pre-tax loss on extinguishment of $2 million related to the difference between the repayment amount and net carrying amount of the Term Loan A Facility, which is included in the Interest expense line item on the Consolidated Statements of Operations.
The 2032 Notes bear interest at a rate of 6.625% per annum. Interest on the 2032 Notes is payable semiannually on April 15 and October 15 of each year, commencing on April 15, 2025. The 2032 Notes will mature on October 15, 2032.
The 2032 Notes are senior unsecured obligations of the Company and are jointly and severally, fully and unconditionally, guaranteed on a senior unsecured basis by certain of the Company’s existing and future direct and indirect domestic restricted subsidiaries that incur or guarantee indebtedness under the Facilities or other qualifying indebtedness that, in the aggregate, exceeds $25 million, including the 2029 Notes.
Senior Notes due 2025
In 2020, the Former Parent completed its acquisition of Delphi Technologies PLC (Delphi Technologies). In connection therewith, the Former Parent completed its offer to exchange Delphi Technologies’ outstanding 5.0% Senior Notes due 2025 (the 2025 Notes). Approximately 97% of the $800 million total outstanding principal amount of the 2025 Notes, were validly exchanged and cancelled for new Former Parent notes. In connection with the Spin-Off, the obligations under the remaining $24 million in aggregate principal amount of the 2025 Notes were assumed
by the Company. On October 1, 2025, the Company paid in full the outstanding $24 million of the 5.0% Senior Notes.

The Company’s long-term debt includes various covenants, none of which are expected to restrict future operations. The Company was in compliance with all covenants as of December 31, 2025.
As of December 31, 2025, the estimated fair values of the Company’s long-term debt totaled $1,011 million, which is $47 million higher than carrying value for the same period. As of December 31, 2024, the estimated fair value of the Company’s long-term debt totaled $1,007 million, which was $21 million higher than carrying value for the same period. Fair market values of the long-term debt 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 other debt facilities approximate fair value. The fair value estimates do not necessarily reflect the values the Company could realize in the current markets.

Derivative Instruments and Hedging Activities Disclosure [Abstract]  
FINANCIAL INSTRUMENTS FINANCIAL INSTRUMENTS
The Company’s financial instruments may include long-term debt, 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.
The Company is exposed to certain market risks relating to our ongoing business operations, including foreign currency exchange rate risk, commodity price risk and interest rate risk. The Company, at times, may use certain financial instruments, primarily derivative contracts, to protect against these risks. The Company uses financial instruments to manage foreign currency exchange rate risk related to forecasted cash flows, including capital expenditures, purchases, operating expenses or sales transactions, and the remeasurement of monetary assets and liabilities denominated in currencies other than the functional currency of the operating unit, and the foreign currency risk exposure associated with our net investment in certain foreign operations.
As of December 31, 2025 and 2024, the United States dollar equivalent notional values of outstanding currency derivative instruments used for foreign currency cash flow hedging were $43 million and $85 million, respectively. These amounts are primarily related to Euro denominated forward contracts at British Pound and Chinese Renminbi functional currency locations.
The Company recognized immaterial amounts of gains and losses in Accumulated other comprehensive loss (AOCI) at December 31, 2025 and 2024 related to derivative instruments designated as foreign currency cash flow hedges, as defined by ASC Topic 815, “Derivatives and Hedging.” The Company also recognized a gain of $3 million in Selling, general and administrative expenses in Net earnings for the year ended December 31, 2025. Balances in AOCI are reclassified to earnings when transactions related to the underlying risk are recognized. At December 31, 2025 and 2024, there were no significant derivative asset or liability balances recorded in the Consolidated Balance Sheets as being payable to or receivable from counterparties under ASC Topic 815, “Derivatives and Hedging”.
The table below shows deferred gains (losses) reported in AOCI related to a $95 million British Pound principal value loan designated as a net investment hedge of a Euro functional holding company’s investment in a British Pound functional subsidiary.

The Company utilizes foreign currency derivatives not designated as hedging instruments to mitigate the variability of the remeasurement of monetary assets and liabilities denominated in currencies other than the operating units' functional currency. In February 2025, the Company entered into a $100 million notional value Chinese Renminbi, U.S. Dollar fixed rate cross-currency swap intended to mitigate the marked-to-market gains and losses of an intercompany loan. The cross-currency swap derivative resulted in a gain of $5 million for the year ended December 31, 2025 which is included in Selling, general and administrative expenses in the Consolidated Statements of Operations. At December 31, 2025, the $5 million fair value of the cross-currency swap is recorded in Prepayments and other current assets in the Consolidated Balance Sheets.

Retirement Benefits [Abstract]  
RETIREMENT BENEFIT PLANS 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.
Prior to the Spin-Off, certain of the Company’s employees participated in defined benefit pension plans sponsored in part by BorgWarner. The Company recorded negligible expense for the year ended 2023 to record its allocation of pension expense related to this plan. In connection with the completion of the Spin-Off, the Company was required to assume additional defined benefit plan liabilities, along with the associated deferred costs in Accumulated other comprehensive loss.
The Company has a number of defined benefit pension plans covering eligible salaried and hourly employees and their dependents. The defined pension benefits provided are primarily based on (1) years of service and (2) average compensation or a monthly retirement benefit amount. The Company provides defined benefit pension plans in France, Germany, India, Japan, Mexico, Turkey, South Korea and the United Kingdom. Some of the Company’s defined benefit plans are frozen, and no additional service cost is being accrued, most notably the U.K. Pension Plan. The measurement date for all plans is December 31.
The following table summarizes the expenses (income) for the Company’s defined contribution and defined benefit pension plans:

 100 %100 % 
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 a total of $12 million to $14 million into its defined benefit pension plans during 2026.
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.
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).
The following tables classify the Company’s defined benefit plan assets measured at fair value on a recurring basis:

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 asset assumptions by evaluating estimates of future market returns and the plans’ asset allocation. The Company also considers the impact of active management of the plans’ invested assets.

STOCK-BASED COMPENSATION

Dec. 31, 2025
Share-Based Payment Arrangement [Abstract]  
STOCK-BASED COMPENSATION 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 PHINIA Inc. 2023 Stock Incentive Plan (2023 Plan). The Company’s Board of Directors adopted the 2023 Plan in July 2023. The 2023 Plan authorizes the issuance of a total of 4.7 million shares. Approximately 3.1 million shares were available for future issuance as of December 31, 2025.
The Former Parent granted 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 (2018 Plan). The Former Parent’s Board of Directors adopted the 2018 Plan in February 2018, and the Former Parent stockholders
approved the 2018 Plan at the annual meeting of stockholders on April 25, 2018. As discussed further below, outstanding awards under the 2018 Plan were replaced with PHINIA equity awards.
Stock-based compensation expense within the consolidated financial statements for periods prior to the Spin-Off was allocated to PHINIA based on the awards and terms previously granted to PHINIA employees while part of BorgWarner and includes the cost of PHINIA employees who participated in the 2018 Plan, as well as an allocated portion of the cost of the Former Parent corporate employee awards.
In connection with the Spin-Off, outstanding equity awards to employees under the 2018 Plan were replaced with PHINIA equity awards using a formula designed to maintain the economic value of the awards immediately before and after the Spin-Off. Accordingly, the number of restricted stock underlying each unvested award outstanding as of the date of the Spin-Off was multiplied by a factor of 1.74, which resulted in no increase in the intrinsic value of awards outstanding. The replaced restricted stock awards continue to vest in accordance with their original vesting period. These replacement awards did not result in additional compensation expense to the Company.
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, PHINIA granted restricted stock in the amount of approximately 210 thousand shares and 30 thousand shares to employees and non-employee directors, respectively. The value of the awards is recognized as compensation expense ratably over the restriction periods, generally two or three years for employees and one year for non-employee directors. As of December 31, 2025, there was $13 million of unrecognized compensation expense related to restricted stock that will be recognized over a weighted average period of approximately 1.5 years.
Restricted stock compensation expense recorded in the Consolidated Statements of Operations is as follows:

Performance stock units: The Company grants performance stock units to members of senior management that vest at the end of three-year periods based on the following metric:
•Total Stockholder Return: This performance metric is based on the Company’s market performance in terms of total stockholder return relative to a peer group of automotive and industrial companies. Based on the Company’s relative ranking within the performance peer group, it is possible for none of the awards to vest or for a range of up to 200% of the target shares to vest.
The Company recognizes compensation expense relating to these performance stock units ratably over the performance period regardless of whether the market conditions are expected to be achieved. Compensation expense associated with these performance stock units are calculated using a lattice model (Monte Carlo simulation).
As of December 31, 2025, there was $10 million of unrecognized compensation expense related to total stockholder return units that will be recognized over a weighted average period of approximately 1.7 years.
The amounts expensed and common stock issued for performance stock units for the years ended December 31, 2025, 2024 and 2023 were as follows:

Commitments and Contingencies Disclosure [Abstract]  
CONTINGENCIES 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, including relating to alleged or actual violations of vehicle emissions standards, general liability and various 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, if not, what the impact might be. The Company records accruals for outstanding legal matters when it believes it is probable that a loss will be incurred and the amount can be reasonably estimated. The Company evaluates, on a quarterly basis, developments in commercial and legal matters that could affect the amount of any accrual and developments that would make a loss contingency both probable and reasonably estimable. If a loss contingency is not both probable and reasonably estimable, the Company does not establish an accrued liability. The Company’s management does not expect that an adverse outcome in any of these commercial and legal claims, actions and complaints that are currently pending will 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, financial position or cash flows.
BorgWarner Dispute
On October 15, 2025, the Company entered into a settlement agreement (the “Settlement Agreement”) with the Former Parent to resolve previously disclosed claims asserted by the Former Parent against the Company, and counterclaims asserted by the Company against the Former Parent, in Delaware Superior Court related to payments and other obligations under the Tax Matters Agreement. The Settlement Agreement provides for, among other things, the Company to make payments to the Former Parent pursuant to the following schedule: an initial payment of $31 million, which was made in the fourth quarter of 2025, a second payment of $21 million, which was made in the first quarter of 2026, and a third and final payment of $26 million to be made over the course of 2026 as the Company receives refunds related to certain indirect tax payments prior to the Spin-Off from various tax
authorities. The Company expects that a substantial portion of these payments will be funded through the refunds obtained by the Company from tax authorities that relate to the indirect tax payments made prior to the Spin-Off, with the remaining portion of the payments to be funded with available liquidity. The Company recorded a $39 million loss in the year ended December 31, 2025 in connection with the settlement, representing the aggregate amount of the payments to be made to the Former Parent less the amount the Company had previously recorded for the matter.
In addition, the Settlement Agreement required the Former Parent to pay to the Company approximately $7 million, which was received in the fourth quarter of 2025, related to the reimbursement of certain pre-Spin-Off corporate income taxes. The Settlement Agreement also provides for the release of certain other claims asserted by the Former Parent against the Company.
In connection with the Settlement Agreement, the Company and the Former Parent also entered into an amendment to the Tax Matters Agreement to provide for, among other things, clarification of the Former Parent’s responsibility for certain pre-Spin-Off tax liabilities and the Company’s ability to obtain and use the benefit of certain pre-Spin-Off credits and other offsets. Although the credits remain subject to completion of necessary filings and governmental approvals, the Company believes these credits can result in the Company receiving up to approximately $29 million in cash.

LEASES AND COMMITMENTS

Leases [Abstract]  
LEASES AND COMMITMENTS 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 Sheet, and lease expense is recognized on a straight-line basis over the lease term.

In the years ended December 31, 2025, 2024 and 2023, the Company recorded operating lease expense of $21 million, $20 million and $15 million, respectively.
In the years ended December 31, 2025, 2024 and 2023, the operating cash flows for operating leases were $20 million.
In the years ended December 31, 2025, 2024 and 2023, the Company recorded short-term lease costs of $4 million, $5 million and $1 million, respectively.
Finance lease costs were immaterial for the periods presented.

LEASES AND COMMITMENTS 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 Sheet, and lease expense is recognized on a straight-line basis over the lease term.

EARNINGS PER SHARE

Dec. 31, 2025
Earnings Per Share [Abstract]  
EARNINGS PER SHARE 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 by the weighted average shares of common stock outstanding during the reporting period. Diluted EPS is calculated by dividing net earnings 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 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 following table reconciles the numerators and denominators used to calculate basic and diluted earnings per share of common stock:

RELATED PARTY RELATED PARTY
Pursuant to the Spin-Off, the Former Parent ceased to be a related party to PHINIA and accordingly, no related party transactions or balances have been reported subsequent to July 3, 2023. In connection with the Spin-Off, we entered into a number of agreements with the Former Parent to govern the Spin-Off and provide a framework for the relationship between the parties going forward, including a Transition Services Agreement, Tax Matters Agreement, and certain Contract Manufacturing Agreements.
The following discussion summarizes activity between the Company and the Former Parent that occurred prior to the completion of the Spin-Off.
Allocation of General Corporate and Other Expenses
The Consolidated Statements of Operations include expenses for certain centralized functions and other programs provided and administered by the Former Parent that were charged directly to the Company prior to the Spin-Off. In addition, for purposes of preparing the financial statements on a carve-out basis, a portion of the Former Parent’s total corporate expenses was allocated to the Company. Similarly, certain centralized expenses incurred by the Company prior to the Spin-Off on behalf of subsidiaries of the Former Parent had been allocated to the Former Parent. See Note 1, “Summary of Significant Accounting Policies,” for a discussion of the methodology used to allocate corporate expenses for purposes of preparing these financial statements on a carve-out basis for periods prior to July 3, 2023.
Net corporate allocation expenses, primarily related to separation and transaction costs, in the year ended December 31, 2023 totaled $89 million. These expenses were primarily included in Selling, general and administrative expenses and Other operating expense, net in the Consolidated Statements of Operations.
Royalty Income from Former Parent and R&D Income from Former Parent
The Company participated in royalty arrangements and provided applications testing and other R&D services to the Former Parent prior to the Spin-Off.

Segment Reporting [Abstract]  
REPORTABLE SEGMENTS AND RELATED INFORMATION REPORTABLE SEGMENTS AND RELATED INFORMATION
The Company’s business is comprised of two reportable segments, which are further described below. These segments are strategic business groups, which are managed separately as each represents a specific grouping of related automotive components and systems.
In the fourth quarter of 2025, the Company made a strategic decision to shift a significant portion of the OES business, previously reported in its Aftermarket segment, to the Fuel Systems segment, as distribution will now be handled by the Fuel Systems locations that manufacture the products. This is expected to streamline the sales structure to external customers while also reducing administrative efforts. The reporting segment disclosures have been updated accordingly which included recasting prior period information for the new reporting structure.
•Fuel Systems. This segment provides advanced fuel injection systems, fuel delivery modules, canisters, sensors, electronic control modules and associated software. Our highly engineered fuel injection systems portfolio includes pumps, injectors, fuel rail assemblies, engine control modules, and complete systems, including software and calibration services, that reduce emissions and improve fuel economy for traditional and hybrid applications.
•Aftermarket. Through this segment, the Company sells products to independent aftermarket customers. Its product portfolio includes a wide range of products as well as maintenance, test equipment and vehicle diagnostics solutions. Additionally, it offers a diverse portfolio of original equipment service solutions and remanufactured products. The Aftermarket segment also includes sales of starters and alternators to OEM and OES customers.
Segment Adjusted Operating Income (AOI) is the measure of segment income or loss used by the Company. Segment AOI is comprised of segment operating income adjusted for restructuring, separation and transaction costs, intangible asset amortization expense, impairment charges, other net expenses and other items not reflective of ongoing operating income or loss. The Company believes Segment AOI is most reflective of the operational profitability or loss of its reportable segments. Segment AOI excludes certain corporate costs, which primarily represent corporate expenses not directly attributable to the individual segments.
The Company’s chief operating decision maker (CODM) is the chief executive officer.
The CODM uses Segment AOI for the financial planning and review process. The CODM considers actual-to-forecast and actual-to-actual variances on a quarterly basis for Segment AOI when making decisions about the allocation of operating and capital resources to each segment. The CODM also uses Segment AOI for evaluating pricing strategy and to assess the performance of each segment by comparing the results of each segment with one another and in determining the compensation of certain employees.
The following tables show segment revenues and significant expenses, Segment AOI, and segment information for the Company’s reportable segments:

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]
Risk Management and Strategy
As part of our overall risk management program, we describe below the processes used to assess, identify, and manage material risks from cybersecurity threats, including how these processes are used to manage cybersecurity risks through our Enterprise Risk Management (ERM) program and for reporting to management and our Board of Directors (the Board). For a description of cybersecurity risks relevant to our business, see Item 1A, “Risk Factors.”
The Company generally approaches cybersecurity threats through a cross-functional, multilayered approach, with the goals of: (i) identifying, preventing and mitigating cybersecurity threats to the Company; (ii) preserving the confidentiality, security and availability of the information we collect and store for use in operating our business; (iii) protecting the Company’s intellectual property; (iv) maintaining the confidence of our customers, suppliers, other business partners and employees; and (v) providing appropriate disclosure of cybersecurity risks and incidents when required. Our cybersecurity and data protection policies, processes and strategies are informed by regulatory and business requirements, our prior experience addressing cybersecurity attacks and incidents (including with our former affiliates), industry practices and standards, and are periodically adjusted based on the results of assessments conducted through our ERM practices, third-party audits and independent reviews, tabletop exercises, and other processes.
Our cybersecurity policies, processes and strategies focus on the following areas:
•Surveillance and Monitoring. The Company maintains 24/7 cybersecurity threat surveillance in conjunction with a managed security service that monitors system logs and network traffic for indicators of compromise and other suspicious activity, and conducts monthly external vulnerability assessments and annual penetration testing.
•System Safeguards. The Company deploys system safeguards that are designed to protect the Company’s technology systems and infrastructure from cybersecurity threats, including early detection and response antivirus tools, data leak prevention tools and systems, vulnerability scans of data centers, firewalls, anti-malware functionality and access controls, and programs to support remediation, replacement or isolation of systems that have reached, or are expected to reach, end of security life.
•Third-Party Collaboration. The Company utilizes collaboration mechanisms established with public and private entities, including intelligence and enforcement agencies, industry groups, and third-party service providers, to identify, assess and respond to cybersecurity risks.
•Third-Party Risk Management. The Company maintains processes designed to identify and oversee material risks from cybersecurity threats associated with third-party users of the Company’s technology systems and data, as well as third-party service providers’ systems used by the Company.
•Training. The Company requires personnel, including new hires, to complete training regarding cybersecurity threats (including phishing, business email compromise and other schemes or attacks that use social engineering, and new disruptors, such as artificial intelligence), incident and threat reporting procedures, data protection and acceptable use of our technology systems.
•Incident Response Planning. The Company maintains a cybersecurity incident response plan that outlines an organized and timely approach for responding to and handling cybersecurity incidents affecting the Company’s technology systems or data, including intrusions or incidents involving data from a third party.
A key part of the Company’s strategy for managing risks from cybersecurity threats is the ongoing assessment and testing of the Company’s policies, processes and strategies through audits, assessments, tabletop exercises, threat modeling, vulnerability testing and other exercises focused on evaluating the effectiveness of our cybersecurity controls and oversight and identifying potential opportunities for enhancements. Third-party audits and independent reviews of our cybersecurity measures, information security control environment and operating effectiveness are conducted on at least an annual basis.
As a global company, we have experienced cybersecurity attacks and incidents in the past, and we could in the future experience similar attacks. To date, risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, have not materially affected the Company and are not reasonably likely to materially affect our business strategy, results of operations, or financial condition.

Governance
The Board, in coordination with the Audit Committee, oversees risks from cybersecurity threats and the Company’s processes for assessing and managing cybersecurity risks. The Board receives updates from management regarding cybersecurity risks and the Company’s processes in connection with its oversight of the Company’s ERM program and risk management practices. The Board also receives updates from the Chief Information Officer (CIO) regarding the Company’s technology systems and infrastructure in connection with its general oversight of the execution and development of key strategies and initiatives. The Audit Committee receives updates from the CIO, supported by the cybersecurity team, including regarding (i) management’s monitoring, assessment and management of cybersecurity risks, (ii) the Company’s strategies and processes for prevention, detection, mitigation, and remediation, and (iii) recent developments, trends and the general threat environment. Updates to the Board or Audit Committee occur on at least a quarterly basis.
The Company’s cybersecurity team, led by our CIO, oversees the Company’s cybersecurity and data security operations, programs, policies and processes and their general effectiveness. Our CIO directly oversees the broader cybersecurity team while the Company actively searches for a Chief Information Security Officer due to a recent vacancy in the position. The cybersecurity team, in coordination with other Incident Response Team members, works collaboratively across the Company to implement a program designed to protect the Company’s technology systems from cybersecurity threats and to promptly respond to cybersecurity incidents. The Company’s Incident Response Team consists of our CIO and other senior leaders from the Company’s cybersecurity (composed of information security and technology operations), compliance, legal, financial reporting and other key business and corporate functions. The CIO and other Incident Response Team members monitor the prevention, detection, mitigation and remediation of cybersecurity incidents in accordance with the incident response plan. The team is also responsible for informing and coordinating with the Company’s Disclosure Committee in timely reporting such incidents, as appropriate and depending on the severity of the incident, and facilitating updates to the Strategy Board (consisting of our CEO, Chief Financial Officer (CFO), General Counsel, CIO and other members of management), Audit Committee and Board regarding such incidents until addressed.
We have experienced leaders responsible for managing and overseeing risks arising from cybersecurity threats. Our CIO reports to the CEO and has significant experience serving in various roles in technology and information security, including CIO of Gentherm Incorporated immediately prior to joining the Company, where he oversaw Gentherm’s cybersecurity program. In addition, the Company’s CEO, CFO and General Counsel each have experience overseeing the management of cybersecurity and other risks similar to those impacting the Company’s business.

Accounting Policies [Abstract]  
Basis of presentation
Basis of presentation Prior to the Spin-Off on July 3, 2023, the historical financial statements of PHINIA were prepared on a stand-alone combined basis and were derived from BorgWarner’s consolidated financial statements and accounting records as if the Fuel Systems and Aftermarket businesses of BorgWarner had been part of PHINIA for all periods presented. Accordingly, for periods prior to July 3, 2023, our financial statements are presented on a combined basis and for the periods subsequent to July 3, 2023 are presented on a consolidated basis (all periods hereinafter are referred to as “consolidated financial statements”). The Company’s Consolidated Financial Statements were prepared in accordance with accounting principles in the United States of America (U.S. GAAP) pursuant to the rules and regulations of the Securities and Exchange Commission (SEC).
Management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and accompanying notes, as well as amounts of revenues and expenses reported during the periods covered by those financial statements and accompanying notes. The Consolidated Financial Statements may not be indicative of the Company’s future performance and do not necessarily reflect what the financial position, results of operations, and cash flows would have been had it operated as a standalone company during the periods presented prior to the Spin-Off.
The Consolidated Statements of Operations include all revenues and costs directly attributable to the Company, including costs for facilities, functions, and services utilized. Costs for certain centralized functions and programs provided and administered by BorgWarner were charged directly to the Company prior to Spin-Off. These centralized functions and programs included, but were not limited to research and development and information technology.
A portion of BorgWarner’s total corporate expenses were allocated to the Company for services rendered by BorgWarner prior to the Spin-Off. These expenses included the cost of corporate functions and resources, including, but not limited to, executive management, finance, accounting, legal, human resources, research and development and sales. Additionally, a portion of the Company’s corporate expenses were allocated to BorgWarner for charges incurred related to subsidiaries of BorgWarner historically supported by the Company, primarily related to information technology. These expenses were allocated based on direct usage when identifiable or, when not directly identifiable, on the basis of proportional net revenues, legal entities, headcount or weighted-square footage, as applicable. The Company considers the basis on which the expenses have been allocated to reasonably reflect the utilization of services provided to, or the benefit received by, both the Company and BorgWarner during the periods presented. However, the allocations may not reflect the expenses the Company would have incurred if the Company had been a standalone company for the periods presented prior to July 3, 2023. The year ended December 31, 2023 included net corporate allocation expenses incurred prior to the Spin-Off totaling $89 million. Corporate allocation expenses were primarily included in Selling, general and administrative expenses.
Use of estimates
Use of estimates The preparation of financial statements in conformity with U.S. 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 Principles of consolidation The Consolidated Financial Statements include all majority-owned subsidiaries with a controlling financial interest. All inter-company balances and transactions have been eliminated in consolidation.
Joint ventures and equity securities
Joint venture and equity securities The Company has an investment in one unconsolidated joint venture: Delphi-TVS Diesel Systems Ltd (D-TVS), of which the Company owns 52.5%. This joint venture is a non-controlled affiliate in which the Company exercises significant influence but does not have a controlling financial interest and, therefore, is accounted for under the equity method. Although the Company is the majority owner, it does not have the ability to control significant decisions or management of the entity. The Company evaluated this investment under Accounting Standards Codification (ASC) Topic 810 and based on the following factors the Company does
not have the power to control the significant decisions of the entity and therefore does not have a controlling financial interest.
•Both partners appoint a managing director and these directors jointly manage all of the affairs of D-TVS, subject to supervision by the board of directors;
•The Company has only a 36% representation on the board of directors; and
•The construct of the board of directors prevents either party from having power/control as described in ASC Topic 810 because both parties lack the ability to directly and/or indirectly control governance and management of D-TVS through either its ownership interest or the board representation.
Generally, under the equity method, the Company’s original investment is recorded at cost and subsequently adjusted by the Company’s share of equity in income or losses. The carrying value of the Company’s investment was $60 million and $51 million as of December 31, 2025 and 2024, respectively. 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 this non-controlled affiliate 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.
Interests in privately held companies that do not have readily determinable fair values are accounted for using the measurement alternative under ASC Topic 321, 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.
Revenue recognition
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 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 the term of the arrangement and recognizes revenue based on the estimated amount of consideration to be received from these arrangements.
Cost of sales
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 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. Cash and cash equivalents are primarily held in foreign locations. 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.
Receivables, net and long-term receivables
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.
Sales of receivables are accounted for in accordance with the ASC Topic 860. Agreements which result in true sales of the transferred receivables, as defined in ASC Topic 860, which occur when receivables are transferred to a third party without recourse to the Company, are excluded from amounts reported in the Consolidated Balance Sheets. Cash proceeds received from such sales are included in operating cash flows. The expenses associated with receivables factoring are recorded in the Consolidated Statements of Operations within interest expense.
Inventories Inventories Inventory is measured using first-in, first-out (FIFO) or average-cost methods at the lower of cost or net realizable value.
Pre-production costs related to long-term supply arrangements
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, 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 fifteen to forty years, and useful lives for machinery and equipment range from three to twelve 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
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 amortizable intangible assets, when events and circumstances warrant such a review under 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 recorded for the amount by which the carrying value of the long-lived asset exceeds its fair value.
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 (1) an assessment as to whether an adverse event or circumstance has triggered the need for an impairment review; (2) undiscounted future cash flows generated by the asset; and (3) fair valuation of the asset.
Goodwill and other indefinite-lived intangible assets
Goodwill and other indefinite-lived intangible assets During the fourth quarter of each year, the Company qualitatively assesses its goodwill. This 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. In addition, the Company also tests goodwill in between annual test dates if an event occurs or circumstances change that could more-likely-than-not reduce the fair value of a reporting unit below its carrying value.
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 expenses are incurred.
Similar to goodwill, the Company can elect to perform the impairment test for indefinite-lived intangibles other than goodwill (trade names) using a qualitative analysis, considering similar factors as outlined in the goodwill discussion in order to determine if it is more-likely-than-not that the fair value of the intangibles are 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 for more information.
Product warranties
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, in certain cases, initial customer claims exceed the amount accrued. Facts may become known related to these claims that may result in additional losses that could be material to the Company’s results of operations or cash flows. The product warranty accrual is allocated to Other current liabilities and Other non-current liabilities in the Consolidated Balance Sheets.
Other loss accruals and valuation allowances
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
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 and are not material.
Government grants 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.
Derivative financial instruments
Derivative financial instruments The Company recognizes that certain normal business transactions and foreign currency operations generate risk. Examples of risks include exposure to 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 consider mitigating such risks through various methods, including financial derivatives. The majority of 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.
Foreign currency
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 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.
Pensions
Pensions  The Company’s defined benefit pension plans are accounted for in accordance with ASC Topic 715. Disability early retirement benefits are accounted for in accordance with ASC Topic 712.
Pension 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 U.S. 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.
Restructuring
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 they are entitled to 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 accrued over the required service period.
Income taxes
Income taxes The Company accounts for income taxes in accordance ASC Topic 740 (ASC 740). Income taxes as presented in the Company’s Consolidated Financial Statements have been allocated in a manner that is systematic, rational, and consistent with the broad principles of ASC 740. Prior to Spin-Off, the Company’s operations have been included in the Former Parent’s U.S. federal consolidated tax return, certain foreign tax returns, and certain state tax returns.
In accordance with ASC 740, 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.
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 credits 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.
