Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	GENERAL General and basis of presentation —In December 2024, Old Aptiv (as defined below), a public limited company formed under the laws of Jersey on May 19, 2011, completed its previously announced reorganization transaction (the “Transaction,” or the “reorganization transaction”), in which Old Aptiv established a new publicly-listed Jersey parent company, Aptiv Holdings Limited (“New Aptiv”), which is resident for tax purposes in Switzerland. As a result of the Transaction, all issued and outstanding ordinary shares of Old Aptiv were exchanged on a one-for-one basis for newly issued ordinary shares of New Aptiv. Following consummation of the Transaction, holders of Old Aptiv shares became ordinary shareholders of New Aptiv, Old Aptiv became a wholly-owned subsidiary of New Aptiv and New Aptiv was renamed “Aptiv PLC.” The previous publicly-listed Jersey parent company, which was an Irish tax resident, is referred to as “Old Aptiv” throughout this Annual Report on Form 10-K. New Aptiv’s ordinary shares are publicly traded on the New York Stock Exchange (“NYSE”) under the symbol “APTV,” the same symbol under which the Old Aptiv shares were previously listed. Aptiv PLC remains a public limited company incorporated under the laws of Jersey, and continues to be subject to U.S. Securities and Exchange Commission reporting requirements. In December 2024, following the completion of the Transaction, Old Aptiv merged with and into Aptiv Swiss Holdings Limited (“Aptiv Swiss Holdings”), a newly formed Jersey incorporated private limited company, and a direct, wholly-owned subsidiary of New Aptiv, with Aptiv Swiss Holdings surviving as a direct, wholly owned subsidiary of New Aptiv, and Old Aptiv ceasing to exist. Except as otherwise noted, all property, rights, privileges, powers and franchises of Old Aptiv vested in Aptiv Swiss Holdings, and all debts, liabilities and duties of Old Aptiv became debts, liabilities and duties of Aptiv Swiss Holdings. In connection with the Transaction, New Aptiv assumed Old Aptiv’s Long-Term Incentive Plans and its existing obligations in connection with awards granted thereunder, and Aptiv Swiss Holdings (i) entered into a supplemental indenture to each indenture in which Aptiv Swiss Holdings assumed all of Old Aptiv’s obligations under each series of Old Aptiv’s outstanding Notes and (ii) entered into an assumption and/or supplement agreement relating to each Credit Agreement in which New Aptiv assumed all of Old Aptiv’s obligations under each Credit Agreement as the “parent entity” thereunder. In addition, New Aptiv (i) entered into a supplemental indenture to each indenture in which New Aptiv guaranteed the outstanding Notes and (ii) entered into a guarantee joinder relating to each Credit Agreement in which New Aptiv guaranteed the obligations under each Credit Agreement. Following the reorganization transaction, Aptiv Swiss Holdings replaced Old Aptiv as an obligor under the Credit Agreements, the senior notes and the junior notes, and New Aptiv became a guarantor under the Credit Agreements (and will act as the “parent entity” thereunder) and the indentures. The Transaction described above was accounted for as a reorganization between entities under common control. As a result of the Transaction, there were no material changes in Aptiv PLC’s operations or governance. The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). References in this Annual Report on Form 10-K, including the exhibits being filed as part of this report, to “Aptiv PLC,” “Aptiv,” the “Company,” “we,” “us” and “our” refers to Old Aptiv (Aptiv PLC before the Transaction in December 2024) and to New Aptiv (Aptiv PLC after the Transaction in December 2024).

Accounting Policies [Abstract]
Significant Accounting Policies	SIGNIFICANT ACCOUNTING POLICIES Consolidation —The consolidated financial statements include the accounts of Aptiv and the subsidiaries in which Aptiv holds a controlling financial or management interest and variable interest entities of which Aptiv has determined that it is the primary beneficiary. Aptiv’s share of the earnings or losses of non-controlled affiliates, over which Aptiv exercises significant influence (generally a 20% to 50% ownership interest), is included in the consolidated operating results using the equity method of accounting. When Aptiv does not have the ability to exercise significant influence (generally when ownership interest is less than 20%), investments in non-consolidated affiliates without readily determinable fair value are measured at cost, less impairments, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer, while investments in publicly traded equity securities are measured at fair value based on quoted prices for identical assets on active market exchanges as of each reporting date. The Company monitors its investments in affiliates for indicators of other-than-temporary declines in value on an ongoing basis. If the Company determines that such a decline has occurred, an impairment loss 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 based on discounted cash flows or negotiated transaction values. Intercompany transactions and balances between consolidated Aptiv businesses have been eliminated. During the years ended December 31, 2024, 2023 and 2022, Aptiv received dividends of $12 million, $5 million and $5 million, respectively, from its equity method investments. The dividends were recognized as a reduction to the investment and represented a return on investment included in cash flows from operating activities. Aptiv’s investments in publicly traded equity securities totaled $11 million and $14 million as of December 31, 2024 and 2023, respectively, and are classified within other long-term assets in the consolidated balance sheets. Aptiv's non-publicly traded investments totaled $167 million and $51 million as of December 31, 2024 and 2023, respectively, and are classified within other long-term assets in the consolidated balance sheets. Refer to Note 5. Investments in Affiliates for further information regarding Aptiv’s investments. In 2022, the Company acquired 85% of the equity interests of Intercable Automotive Solutions S.r.l. (“Intercable Automotive”). Concurrent with the acquisition, the Company entered into an agreement with the noncontrolling interest holders that provides the Company with the right to purchase, and the noncontrolling interest holders with the right to sell, the remaining 15% of Intercable Automotive for cash at a contractually defined value beginning in 2026. As a result of this redemption feature, the Company recorded the redeemable noncontrolling interest at its acquisition-date fair value to temporary equity in the consolidated balance sheet. The redeemable noncontrolling interest is adjusted each reporting period for the income (loss) attributable to the noncontrolling interest, and for any measurement period adjustments necessary to record the redeemable noncontrolling interest at the higher of its redemption value, assuming it was redeemable at the reporting date, or its carrying value. Any measurement period adjustments are recorded to retained earnings, with a corresponding increase or reduction to net income attributable to Aptiv. Redeemable noncontrolling interest was $92 million and $99 million as of December 31, 2024 and 2023, respectively. Refer to Note 20. Acquisitions and Divestitures for further information regarding this acquisition and the redeemable noncontrolling interest. Use of estimates —Preparation of consolidated financial statements in conformity with U.S. GAAP requires the use of estimates and assumptions that affect amounts reported therein. Generally, matters subject to estimation and judgment include amounts related to accounts receivable realization, inventory obsolescence, asset impairments, useful lives of intangible and fixed assets, deferred tax asset valuation allowances, income taxes, pension benefit plan assumptions, accruals related to litigation, warranty costs, environmental remediation costs, contingent consideration arrangements, redeemable noncontrolling interest, worker’s compensation accruals and healthcare accruals. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be based upon amounts that differ from those estimates. Revenue recognition —Revenue is measured based on consideration specified in a contract with a customer. Customer contracts for production parts generally are represented by a combination of a current purchase order and a current production schedule issued by the customer. Substantially all of the Company's revenue is generated from the sale of manufactured production parts, wherein there is a single performance obligation. Transfer of control and revenue recognition for the Company’s sales of production parts generally occurs upon shipment or delivery of the product, which is when title, ownership, and risk of loss pass to the customer and is based on the applicable customer shipping terms. Revenue is measured based on the transaction price and the quantity of parts specified in a contract with a customer. Refer to Note 24. Revenue for further detail of the Company’s accounting for its revenue from sales of production parts. Customer contracts for software licenses are generally represented by a sales contract or purchase order with contract durations typically ranging from one to three years. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. Revenue from software licenses and professional software services is generally recognized at a point in time upon delivery or when the services are provided. Revenue from post delivery support and maintenance for software contracts is generally recognized over time on a ratable basis over the contract term. Certain software license contracts contain multiple performance obligations, for which the Company allocates the contract’s transaction price to each performance obligation based on the estimated relative standalone selling price of each distinct performance obligation in the contract. The standalone selling prices are generally determined based on observable inputs, such as the prices of standalone sales and historical contract pricing. Under certain of these arrangements, timing may differ between revenue recognition and billing. Refer to Note 24. Revenue for further detail of the Company’s accounting for its revenue from contracts with customers, including contract balances associated with software sales. From time to time, Aptiv enters into pricing agreements with its customers that provide for price reductions on production parts, some of which are conditional upon achieving certain joint cost saving targets, which are accounted for as variable consideration. In these instances, revenue is recognized based on the agreed-upon price at the time of shipment if available, or in the event the Company concludes that a portion of the revenue for a given part may vary from the purchase order and requires estimation, the Company records consideration at the most likely amount that the Company expects to be entitled to based on historical experience and input from customer negotiations. Sales incentives and allowances are recognized as a reduction to revenue at the time of the related sale. In addition, from time to time, Aptiv makes payments to customers in conjunction with ongoing business. These payments to customers are generally recognized as a reduction to revenue at the time of the commitment to make these payments. However, certain other payments to customers, or upfront fees, meet the criteria to be considered a cost to obtain a contract as they are directly attributable to a contract, are incremental and management expects the fees to be recoverable. Aptiv collects and remits taxes assessed by different governmental authorities that are both imposed on and concurrent with a revenue-producing transaction between the Company and the Company’s customers. These taxes may include, but are not limited to, sales, use, value-added, and some excise taxes. Aptiv reports the collection of these taxes on a net basis (excluded from revenues). Shipping and handling fees billed to customers are included in net sales, while costs of shipping and handling are included in cost of sales. Refer to Note 24. Revenue for further information. Net income per share —Basic net income per share is computed by dividing net income attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period. Diluted net income per share reflects the weighted average dilutive impact of all potentially dilutive securities from the date of issuance and is computed using the treasury stock and if-converted methods. Prior to the conversion of the 5.50% Mandatory Convertible Preferred Shares, Series A, $0.01 par value per share (the “MCPS”) into ordinary shares in June 2023, the if-converted method was used to determine if the impact of the conversion of the MCPS into ordinary shares was more dilutive than the MCPS dividends to net income per share. If so, the MCPS were assumed to have been converted at the later of the beginning of the period or the time of issuance, and the resulting ordinary shares were included in the denominator and the MCPS dividends were added back to the numerator. Unless otherwise noted, share and per share amounts included in these notes are on a diluted basis. Refer to Note 15. Shareholders’ Equity and Net Income Per Share for additional information including the calculation of basic and diluted net income per share. Research and development —Costs are incurred in connection with research and development programs that are expected to contribute to future earnings. Such costs are charged against income as incurred. Total research and development expenses, including engineering, net of customer reimbursements, were approximately $1,097 million, $1,289 million and $1,120 million for the years ended December 31, 2024, 2023 and 2022, respectively. Cash and cash equivalents —Cash and cash equivalents are defined as short-term, highly liquid investments with original maturities of three months or less, for which the book value approximates fair value. Restricted cash —Restricted cash primarily includes balances on deposit at financial institutions that have issued letters of credit in favor of Aptiv and cash deposited into escrow accounts. Short-term investments —Short-term investments are comprised of term deposits with original maturities greater than three months, for which book value approximates fair value. As described further in Note 11. Debt, these short-term investments were utilized to redeem the €700 million in aggregate principal amount of 1.50% Euro-denominated senior unsecured notes due 2025 (the “2015 Euro-denominated Senior Notes”) in December 2024. Accounts receivable —Aptiv enters into agreements to sell certain of its accounts receivable, primarily in Europe. Sales of receivables are accounted for in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 860, Transfers and Servicing (“ASC 860”). Agreements which result in true sales of the transferred receivables, as defined in ASC 860, which occur when receivables are transferred 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. Agreements that allow Aptiv to maintain effective control over the transferred receivables and which do not qualify as a sale, as defined in ASC 860, are accounted for as secured borrowings and recorded in the consolidated balance sheets within accounts receivable, net and short-term debt. The expenses associated with receivables factoring are recorded in the consolidated statements of operations within interest expense. The Company exchanges certain amounts of accounts receivable, primarily in the Asia Pacific region, for bank notes with original maturities greater than three months. The collection of such bank notes are included in operating cash flows based on the substance of the underlying transactions, which are operating in nature. Bank notes held by the Company with original maturities of three months or less are classified as cash and cash equivalents within the consolidated balance sheets, and those with original maturities of greater than three months are classified as notes receivable within other current assets. The Company may hold such bank notes until maturity, exchange them with suppliers to settle liabilities, or sell them to third-party financial institutions in exchange for cash. Credit losses —Aptiv is exposed to credit losses primarily through the sale of vehicle components, software licenses and services. Aptiv assesses the creditworthiness of a counterparty by conducting ongoing credit reviews, which considers the Company’s expected billing exposure and timing for payment, as well as the counterparty’s established credit rating. When a credit rating is not available, the Company’s assessment is based on an analysis of the counterparty’s financial statements. Aptiv also considers contract terms and conditions, country and political risk, and business strategy in its evaluation. Based on the outcome of this review, the Company establishes a credit limit for each counterparty. The Company continues to monitor its ongoing credit exposure through active review of counterparty balances against contract terms and due dates, which includes timely account reconciliation, payment confirmation and dispute resolution. The Company may also employ collection agencies and legal counsel to pursue recovery of defaulted receivables, if necessary. Aptiv primarily utilizes historical loss and recovery data, combined with information on current economic conditions and reasonable and supportable forecasts to develop the estimate of the allowance for doubtful accounts in accordance with ASC Topic 326, Financial Instruments – Credit Losses (“ASC 326”). As of December 31, 2024 and December 31, 2023, the Company reported $3,261 million and $3,546 million, respectively, of accounts receivable, net of the allowances, which includes the allowance for doubtful accounts of $37 million and $52 million, respectively. The provision for doubtful accounts was $11 million, $12 million, and $27 million for the years ended December 31, 2024, 2023 and 2022, respectively. Other changes in the allowance were not material for the year ended December 31, 2024. Inventories —As of December 31, 2024 and 2023, inventories are stated at the lower of cost, determined on a first-in, first-out basis, or net realizable value, including direct material costs and direct and indirect manufacturing costs. Refer to Note 3. Inventories for additional information. Obsolete inventory is identified based on analysis of inventory for known obsolescence issues, and, generally, the net realizable value of inventory on hand in excess of one year’s supply is fully-reserved. From time to time, payments may be received from suppliers. These payments from suppliers are recognized as a reduction of the cost of the material acquired during the period to which the payments relate. In some instances, supplier rebates are received in conjunction with or concurrent with the negotiation of future purchase agreements and these amounts are amortized over the prospective agreement period as purchases are made. Property —Major improvements that materially extend the useful life of property are capitalized. Expenditures for repairs and maintenance are charged to expense as incurred. Depreciation is determined based on a straight-line method over the estimated useful lives of groups of property. Leasehold improvements under finance leases are depreciated over the period of the lease or the life of the property, whichever is shorter. Refer to Note 6. Property, Net and Note 25. Leases for additional information. Pre-production costs related to long-term supply agreements —The Company incurs pre-production engineering, development and tooling costs related to products produced for its customers under long-term supply agreements. Engineering, testing and other costs incurred in the design and development of production parts are expensed as incurred, unless the costs are reimbursable, as specified in a customer contract. As of December 31, 2024 and 2023, $305 million and $285 million of such contractually reimbursable costs were capitalized, respectively. These amounts are recorded within other current and other long-term assets in the consolidated balance sheets, as further detailed in Note 4. Assets. Special tools represent Aptiv-owned tools, dies, jigs and other items used in the manufacture of customer components that will be sold under long-term supply arrangements, the costs of which are capitalized within property, plant and equipment if the Company has title to the assets. Special tools also include capitalized unreimbursed pre-production tooling costs related to customer-owned tools for which the customer has provided Aptiv a non-cancellable right to use the tool. Aptiv-owned special tool balances are depreciated over the expected life of the special tool or the life of the related vehicle program, whichever is shorter. The unreimbursed costs incurred related to customer-owned special tools that are not subject to reimbursement are capitalized and depreciated over the expected life of the special tool or the life of the related vehicle program, whichever is shorter. At December 31, 2024 and 2023, the special tools balance, net of accumulated depreciation, was $489 million and $474 million, respectively, included within property, net in the consolidated balance sheets. As of December 31, 2024 and 2023, the Aptiv-owned special tools balance was $361 million and $373 million, respectively, and the customer-owned special tools balance was $128 million and $101 million, respectively. Valuation of long-lived assets —The carrying value of long-lived assets held for use, including definite-lived intangible assets, is periodically evaluated when events or circumstances warrant such a review. The carrying value of a long-lived asset held for use is considered impaired when the anticipated separately identifiable undiscounted cash flows from the asset are less than the carrying value of the asset. In that event, a loss is recognized based on the amount by which the carrying value exceeds the estimated fair value of the long-lived asset. Impairment losses on long-lived assets held for sale are recognized if the carrying value of the asset is in excess of the asset’s estimated fair value, reduced for the cost to dispose of the asset. Fair value of long-lived assets is determined primarily using the anticipated cash flows discounted at a rate commensurate with the risk involved (an income approach), and in certain situations Aptiv’s review of appraisals (a market approach). Refer to Note 6. Property, Net and Note 7. Intangible Assets and Goodwill for additional information. Leases —The Company accounts for leases in accordance with FASB ASC Topic 842, Leases . The Company determines whether an arrangement is a lease at inception. For leases where the Company is the lessee, a lease liability and a right-of-use asset is recognized for all leases, with the exception of short-term leases with terms of twelve months or less. The lease liability represents the lessee’s obligation to make lease payments arising from a lease, and is measured as the present value of the lease payments. As the rate implicit in the lease is usually not known at lease commencement, the Company uses its incremental borrowing rate to discount the lease obligation. The right-of-use asset represents the lessee’s right to use a specified asset for the lease term, and is measured at the lease liability amount, adjusted for lease prepayment, lease incentives received and the Company’s initial direct costs. The Company applies the short-term lease exception, which results in a single lease cost being allocated over the lease term, generally on a straight-line basis, for leases with a term of twelve months or less. These leases are not presented in the consolidated balance sheets. Additionally, the Company applies the practical expedient to not separate lease components from non-lease components and instead accounts for both as a single lease component for all asset classes. Refer to Note 25. Leases for additional information. Assets and liabilities held for sale —The Company considers assets to be held for sale when management, having the appropriate authority, approves and commits to a formal plan to actively market the assets for sale at a price reasonable in relation to their estimated fair value, the assets are available for immediate sale in their present condition, an active program to locate a buyer and other actions required to complete the sale have been initiated, the sale of the assets is probable and expected to be completed within one year and it is unlikely that significant changes will be made to the plan. Upon designation as held for sale, the Company records the assets at the lower of their carrying value or their estimated fair value, less cost to sell, and ceases to record depreciation expense on the assets. Assets and liabilities of a discontinued operation are reclassified as held for sale for all comparative periods presented in the consolidated balance sheets. For assets that meet the held for sale criteria but do not meet the definition of a discontinued operation, the Company reclassifies the assets and liabilities in the period in which the held for sale criteria are met, but does not reclassify prior period amounts. Intangible assets —The Company amortizes definite-lived intangible assets over their estimated useful lives. The Company has definite-lived intangible assets related to patents and developed technology, customer relationships and trade names. Indefinite-lived in-process research and development intangible assets are not amortized, but are tested for impairment annually, or more frequently when indicators of potential impairment exist, until the completion or abandonment of the associated research and development efforts. Upon completion of the projects, the assets will be amortized over the expected economic life of the asset, which will be determined on that date. Should the project be determined to be abandoned, and if the asset developed has no alternative use, the full value of the asset will be charged to expense. 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. These indefinite-lived trade name assets are tested for impairment annually, or more frequently when indicators of potential impairment exist. Costs to renew or extend the term of acquired intangible assets are recognized as expense as incurred. No intangible asset impairment charges were recorded during the years ended December 31, 2024, 2023 and 2022. Refer to Note 7. Intangible Assets and Goodwill for additional information. Goodwill —Goodwill is the excess of the purchase price over the estimated fair value of identifiable net assets acquired in business combinations. The Company tests goodwill for impairment annually in the fourth quarter, or more frequently when indications of potential impairment exist. The Company monitors the existence of potential impairment indicators throughout the fiscal year. The Company tests for goodwill impairment at the reporting unit level. Our reporting units are the components of operating segments which constitute businesses for which discrete financial information is available and is regularly reviewed by segment management. The impairment test involves first qualitatively assessing goodwill for impairment. If the qualitative assessment is not met the Company then performs a quantitative assessment by comparing the estimated fair value of each reporting unit to its carrying value, including goodwill. Fair value reflects the price a market participant would be willing to pay in a potential sale of the reporting unit. If the estimated fair value exceeds carrying value, then we conclude that no goodwill impairment has occurred. If the carrying value of the reporting unit exceeds its estimated fair value, the Company recognizes an impairment loss in an amount equal to the excess, not to exceed the amount of goodwill allocated to the reporting unit. When a quantitative assessment is required, the estimated fair value of the Company’s reporting units is primarily determined using discounted cash flow projections. Significant assumptions include management’s forecasted cash flows, including estimated future revenue growth, and the discount rate. Forecasts of future cash flows are based on management’s best estimates. The discount rate is determined using a weighted average cost of capital adjusted for risk factors specific to the reporting unit. The fair value of the reporting unit’s goodwill is sensitive to differences between estimated and actual cash flows, including changes in the projected revenue and discount rate. Refer to Note 20. Acquisitions and Divestitures, for further information on the goodwill attributable to the Company’s acquisitions. Goodwill impairment —The Company performs an annual goodwill impairment assessment in the fourth quarter. In 2024, the Company completed a qualitative goodwill impairment assessment and, after evaluating the results, events and circumstances of the Company, we concluded that sufficient evidence existed to assert qualitatively that it was more likely than not that the estimated fair value of all but one of our reporting units remained in excess of their carrying values. The Company performed a quantitative goodwill impairment test for its Wind River reporting unit within the Advanced Safety and User Experience segment, which has goodwill of $2,279 million, and determined its fair value to be in excess of its carrying value by less than 1%. No goodwill impairments were recorded in 2024, 2023 or 2022. Refer to Note 7. Intangible Assets and Goodwill for additional information. Although we believe our estimate of fair value is reasonable based on current and future market conditions and the best information available at the impairment assessment date, the reporting unit’s future financial performance is dependent on our ability to execute our business plan. Future changes in the judgments, assumptions and estimates used in our impairment testing for goodwill, including discount rates and cash flow projections, could result in significantly different estimates of the fair value. A reduction in the estimated fair value could result in non-cash impairment charges in a future period. Warranty and product recalls —Expected warranty costs for products sold are recognized at the time of sale of the product based on an estimate of the amount that eventually will be required to settle such obligations. These accruals are based on factors such as past experience, production changes, industry developments and various other considerations. 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 our warranty accrual at the time an obligation becomes probable and can be reasonably estimated. These estimates are adjusted from time to time based on facts and circumstances that impact the status of existing claims. Refer to Note 9. Warranty Obligations for additional information. Income taxes —Deferred tax assets and liabilities reflect temporary differences between the amount of assets and liabilities for financial and tax reporting purposes. Such amounts are adjusted, as appropriate, to reflect changes in tax rates expected to be in effect when the temporary differences reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period that includes the enactment date. A valuation allowance is recorded to reduce deferred tax assets to the amount that is more likely than not to be realized. In the event the Company determines it is more likely than not that the deferred tax assets will not be realized in the future, the valuation allowance adjustment to the deferred tax assets will be charged to earnings in the period in which the Company makes such a determination. In determining whether an uncertain tax position exists, the Company determines, based solely on its technical merits, whether the tax position is more likely than not to be sustained upon examination, and if so, a tax benefit is measured on a cumulative probability basis that is more likely than not to be realized upon the ultimate settlement. In determining the provision for income taxes for financial statement purposes, the Company makes certain estimates and judgments which affect its evaluation of the carrying value of its deferred tax assets, as well as its calculation of certain tax liabilities. As it relates to changes in accumulated other comprehensive income (loss), the Company’s policy is to release tax effects from accumulated other comprehensive income (loss) when the underlying components affect earnings. Refer to Note 14. Income Taxes for additional information. Foreign currency translation —Assets and liabilities of non-U.S. subsidiaries that use a currency other than U.S. dollars as their functional currency are translated to U.S. dollars at end-of-period currency exchange rates. The consolidated statements of operations of non-U.S. subsidiaries are translated to U.S. dollars at average-period currency exchange rates. The effect of translation for non-U.S. subsidiaries is generally reported in other comprehensive income (“OCI”). The accumulated foreign currency translation adjustment related to an investment in a foreign subsidiary is reclassified to net income upon sale or upon complete or substantially complete liquidation of the respective entity. The effect of remeasurement of assets and liabilities of non-U.S. subsidiaries that use the U.S. dollar as their functional currency is primarily included in cost of sales. Also included in cost of sales are gains and losses arising from transactions denominated in a currency other than the functional currency of a particular entity. Net foreign currency transaction losses of $1 million, $23 million and $30 million were included in the consolidated statements of operations for the year ended December 31, 2024, 2023 and 2022, respectively. Restructuring —Aptiv continually evaluates alternatives to align the business with the changing needs of its customers and to lower operating costs. This includes the realignment of its existing manufacturing capacity, facility closures, or similar actions, either in the normal course of business or pursuant to significant restructuring programs. These actions may result in employees receiving voluntary or involuntary employee termination benefits, which are mainly pursuant to union or other contractual agreements or statutory requirements. Voluntary termination benefits are accrued when an employee accepts the related offer. Involuntary termination benefits are accrued upon the commitment to a termination plan and when the benefit arrangement is communicated to affected employees, or when liabilities are determined to be probable and estimable, depending on the existence of a substantive plan for severance or termination. Contract termination costs and certain early termination lease costs are recorded when contracts are terminated. All other exit costs are expensed as incurred. Refer to Note 10. Restructuring for additional information. Customer concentrations —We sell our products and services to the major global OEMs in every region of the world. Our ten largest customers accounted for approximately 55%, 54% and 55% of our tota

Equity Method Investments and Joint Ventures [Abstract]
Investments in Affiliates	INVESTMENTS IN AFFILIATES Equity Method Investments As part of Aptiv’s operations, it has investments in five non-consolidated affiliates accounted for under the equity method of accounting. These affiliates are not publicly traded companies and are located primarily in North America, Europe and Asia Pacific. Aptiv’s ownership percentages vary generally from approximately 15% to 50%, with the most significant investments being in Motional AD LLC (“Motional”) (of which Aptiv owns 15%), TTTech Auto AG (“TTTech Auto”) (of which Aptiv owns approximately 20%) and in Promotora de Partes Electricas Automotrices, S.A. de C.V. (of which Aptiv owns approximately 40%). The Company’s aggregate investments in affiliates was $1,433 million and $1,443 million at December 31, 2024 and 2023, respectively. Dividends of $12 million, $5 million and $5 million for the years ended December 31, 2024, 2023 and 2022, respectively, have been received from these non-consolidated affiliates. During the year ended December 31, 2024, Aptiv recorded a non-cash, pre-tax impairment charge of approximately $36 million for TTTech Auto, as described below, within net gain on equity method transactions in the consolidated statements of operations. There were no impairment charges recorded for the years ended December 31, 2023 and 2022. The following is a summary of the combined financial information of significant affiliates accounted for under the equity method as of December 31, 2024 and 2023 and for the years ended December 31, 2024, 2023 and 2022: December 31, 2024 2023 (in millions) Current assets $ 727 $ 681 Non-current assets 2,432 2,499 Total assets $ 3,159 $ 3,180 Current liabilities $ 235 $ 222 Non-current liabilities 73 86 Shareholders’ equity 2,851 2,872 Total liabilities and shareholders’ equity $ 3,159 $ 3,180 Year Ended December 31, 2024 2023 2022 (in millions) Net sales $ 974 $ 813 $ 761 Gross loss $ (136) $ (327) $ (357) Net loss $ (397) $ (624) $ (589) A summary of transactions with affiliates is shown below: Year Ended December 31, 2024 2023 2022 (in millions) Sales to affiliates $ 15 $ 15 $ 35 Purchases from affiliates $ 8 $ 15 $ 18 A summary of amounts recorded in the Company’s consolidated balance sheets related to its affiliates is shown below: December 31, 2024 2023 (in millions) Receivables due from affiliates $ — $ 2 Payables due to affiliates $ 13 $ 13 Motional Joint Venture Funding and Ownership Restructuring Transactions On April 19, 2024, Aptiv and Hyundai Motor Group (“Hyundai”) entered into an agreement to restructure Aptiv’s ownership interest in Motional and for Hyundai to provide additional funding to Motional, each as described below. Prior to these transactions, Motional was 50% owned by each of Aptiv and Hyundai. As part of the agreement, on May 2, 2024, Hyundai invested $475 million in Motional in exchange for an additional 11.7% common equity interest. Aptiv did not participate in this funding round. This transaction resulted in the dilution of Aptiv’s common equity interest in Motional from 50% to approximately 44%, prior to the completion of any further transactions as described below. As these units were issued at a valuation greater than the carrying value of our investment in Motional, the Company recognized a gain of approximately $91 million during the year ended December 31, 2024, within net gain on equity method transactions in the consolidated statements of operations. Also as part of the agreement, on May 16, 2024, Aptiv sold 11% of its common equity interest in Motional to Hyundai for approximately $448 million of cash consideration. Aptiv also exchanged approximately 21% of its common equity in Motional for a like number of Motional preferred shares. These transactions resulted in the reduction of Aptiv’s common equity interest in Motional from approximately 44% to approximately 15%. As a result of these transactions, the Company recognized a gain of approximately $550 million during the year ended December 31, 2024, within net gain on equity method transactions in the consolidated statements of operations. The total gain recorded as a result of the Motional funding and ownership restructuring transactions completed in May 2024, all as described above, was approximately $641 million ($2.50 per diluted share) for the year ended December 31, 2024. As of December 31, 2024, the carrying values of the Company’s common equity and preferred equity investments in Motional were $256 million and $899 million, respectively. As of December 31, 2023, the carrying value of the Company’s common equity investment in Motional was $1,096 million. These investments are recorded within investment in affiliates in the consolidated balance sheets and included in the Advanced Safety and User Experience segment. The Company's preferred equity investment in Motional was initially measured at fair value, and subsequently accounted for under the measurement alternative in accordance with ASC Topic 321, Investments – Equity Securities , as it does not have a readily determinable fair value. Investment in TTTech Auto AG On March 15, 2022, Aptiv acquired approximately 20% of the equity interests of TTTech Auto, a leading provider of safety-critical middleware solutions for advanced driver-assistance systems and autonomous driving applications, for €200 million (approximately $220 million, using foreign currency rates on the investment date). The Company made the investment in TTTech Auto utilizing cash on hand. The shareholders of TTTech Auto entered into an agreement for the sale of 100% of TTTech Auto to an unrelated third party. As a result, the Company determined there was an other-than-temporary impairment to its equity method investment in TTTech Auto in the fourth quarter of 2024 based on the anticipated acquisition value of TTTech Auto. During the year ended December 31, 2024, the Company’s equity investment in TTTech Auto was written down to its estimated fair value of $147 million, resulting in a non-cash, pre-tax impairment charge of approximately $36 million within net gain on equity method transactions in the consolidated statements of operations. Upon completion of the sale, Aptiv will no longer hold an equity interest in TTTech Auto. The sale is anticipated to occur in 2025 and is subject to regulatory approvals and customary closing conditions. The impairment was based on the fair value of the investment at the balance sheet date. The fair value was determined based on the contractual sales price of TTTech Auto pursuant to the executed purchase and sale agreement. Contractual sales prices are considered observable inputs other than quoted prices, and are therefore classified as a Level 2 measurement. As of December 31, 2024 and 2023, the carrying value of the Company’s investment in TTTech Auto was $147 million and $200 million, respectively, which is included in the Advanced Safety and User Experience segment. As of December 31, 2024 and 2023, the difference between the amount at which the Company’s investment is carried and the amount of the Company’s share of the underlying equity in net assets of TTTech Auto was approximately $111 million and $156 million, respectively. The basis difference is primarily attributable to equity method goodwill associated with the investment, which is not amortized. Technology Investments The Company has made technology investments in certain non-consolidated affiliates for which Aptiv does not have the ability to exercise significant influence (generally when ownership interest is less than 20%) as described in Note 2. Significant Accounting Policies. Equity investments in nonconsolidated affiliates without readily determinable fair values are measured at cost, less impairments, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer. Investments in available-for-sale debt securities are measured at fair value based on significant inputs that are not observable in the market. Equity investments in publicly traded equity securities are measured at fair value based on quoted prices for identical assets on active market exchanges. The following is a summary of technology investments, which are classified within other long-term assets in the consolidated balance sheets, as of December 31, 2024 and 2023: December 31, Investment Name Segment 2024 2023 (in millions) Publicly traded equity securities: Smart Eye AB Advanced Safety and User Experience $ 5 $ 8 Urgently, Inc.

Advanced Safety and User Experience 55 — Other investments Various 6 7 Total non-publicly traded investments 167 51 Total technology investments $ 178 $ 65 In September 2024, the Company’s Advanced Safety and User Experience segment made an investment totaling approximately 399 million Chinese Yuan Renminbi (“RMB”) (approximately $57 million, using foreign currency rates on the investment date) in preferred equity of MAXIEYE Automotive Technology (Ningbo) Co., Ltd. (“Maxieye”), a provider of advanced driver-assistance systems and autonomous driving applications. Due to the Company’s redemption rights, the Company’s investment in Maxieye is classified as an available-for-sale debt security within other long-term assets in the consolidated balance sheets, with changes in fair value recorded in other comprehensive income. The Company also agreed to invest an additional 171 million RMB (approximately $24 million, using December 31, 2024 foreign currency rates) in preferred equity of Maxieye, contingent on the achievement of certain technical milestones, which have not yet been met as of December 31, 2024, and the satisfaction of customary closing conditions. As of December 31, 2024, the Company’s investment in Maxieye was recorded at $55 million. Refer to Note 18. Fair Value of Financial Instruments for additional information. In July 2024, the Company’s Advanced Safety and User Experience segment made an investment of approximately 33 billion Korean Won (“KRW”) (approximately $24 million, using foreign currency rates on the investment date) in convertible redeemable preferred shares of StradVision, Inc. (“StradVision”), a provider of deep learning-based camera perception software for automotive applications. The Company previously made KRW-denominated investments in StradVision totaling approximately $40 million in the first quarter of 2024 and approximately $44 million in prior years (using foreign currency rates on the date of the respective investments). Due to the Company’s redemption rights, the Company’s investment in StradVision is classified as an available-for-sale debt security within other long-term assets in the consolidated balance sheets, with changes in fair value recorded in other comprehensive income. As of December 31, 2024, the Company’s investment in StradVision was recorded at $106 million. Refer to Note 18. Fair Value of Financial Instruments for additional information. The Company evaluated the measurement guidance for equity securities without a readily determinable fair value and performed a qualitative assessment of various impairment indicators and concluded that one of its equity investments was impaired. As a result, the Company recognized an impairment loss of $18 million during the year ended December 31, 2023, within other income (expense), net in the consolidated statements of operations. The impairment recorded was equal to the difference between the fair value of Aptiv’s ownership interest in the investment and its carrying amount. As of December 31, 2024, none of the Company’s equity securities were subject to contractual sales restrictions prohibiting the sale of securities. There were no other material transactions, events or changes in circumstances requiring an impairment or an observable price change adjustment to our investments without readily determinable fair value. The Company continues to monitor these investments to identify potential transactions which may indicate an impairment or an observable price change requiring an adjustment to its carrying value.

Product Warranties Disclosures [Abstract]
Warranty Obligations	WARRANTY OBLIGATIONS Expected warranty costs for products sold are recognized principally at the time of sale of the product based on an estimate of the amount that eventually will be required to settle such obligations. These accruals are based on factors such as past experience, production changes, industry developments and various other considerations. The estimated costs related to product recalls based on a formal campaign soliciting return of that product are accrued at the time an obligation becomes probable and can be reasonably estimated. These estimates are adjusted from time to time based on facts and circumstances that impact the status of existing claims. Aptiv has recognized a reasonable estimate for its total aggregate warranty reserves, including product recall costs, across all of its operating segments as of December 31, 2024. The Company estimates the reasonably possible amount to ultimately resolve all matters in excess of the recorded reserves as of December 31, 2024 to be zero to $40 million. The table below summarizes the activity in the product warranty liability for the years ended December 31, 2024 and 2023: Year Ended December 31, 2024 2023 (in millions) Accrual balance at beginning of year $ 61 $ 52 Provision for estimated warranties incurred during the year 33 31 Changes in estimate for pre-existing warranties 38 23 Settlements (57) (47) Foreign currency translation and other (1) 2 Accrual balance at end of year $ 74 $ 61

Restructuring and Related Activities [Abstract]
Restructuring and Related Activities Disclosure [Text Block]	RESTRUCTURING Aptiv’s restructuring activities are undertaken as necessary to implement management’s strategy, streamline operations, take advantage of available capacity and resources, and ultimately achieve net cost reductions. These activities generally relate to the realignment of existing manufacturing capacity and closure of facilities and other exit or disposal activities, as it relates to executing Aptiv’s strategy, either in the normal course of business or pursuant to significant restructuring programs. As part of the Company’s continued efforts to optimize its cost structure, it has undertaken several restructuring programs which include workforce reductions as well as plant closures. These programs are primarily focused on reducing global overhead costs, the continued rotation of our manufacturing footprint to best cost locations in Europe and aligning our manufacturing capacity with the current levels of automotive production in each region. During the year ended December 31, 2024, the Company recorded employee-related and other restructuring charges related to these programs totaling approximately $193 million, of which $25 million and $57 million were recognized for programs initiated in the fourth quarter of 2024 and 2023, respectively, focused on global salaried workforce optimization, primarily in the North American and European regions. We expect to recognize additional charges of approximately $35 million in 2025 related to the restructuring program initiated in the fourth quarter of 2024, with cash payments expected to be principally completed in 2025. There have been no changes in previously initiated programs that have resulted (or are expected to result) in a material change to our restructuring costs. The Company expects to incur additional restructuring costs of approximately $55 million (of which approximately $40 million relates to the Signal and Power Solutions segment and approximately $15 million relates to the Advanced Safety and User Experience segment) for programs approved as of December 31, 2024, inclusive of $35 million related to the global salaried headcount reduction program described above, and are expected to be incurred within the next twelve months. During the year ended December 31, 2023, Aptiv recorded employee-related and other restructuring charges totaling approximately $211 million, of which $68 million was recognized for a program initiated in the fourth quarter of 2023 focused on global salaried workforce optimization, primarily in the North American and European regions. The charges recorded during the year ended December 31, 2023 also included the recognition of approximately $27 million of employee-related and other costs related to the initiation of the closure of a Western European manufacturing site within the Advanced Safety and User Experience segment pursuant to the Company’s ongoing European footprint rotation strategy. Restructuring charges for employee separation and termination benefits are paid either over the severance period or in a lump sum in accordance with either statutory requirements or individual agreements. Aptiv incurred cash expenditures related to its restructuring programs of approximately $238 million, $128 million and $67 million in the years ended December 31, 2024, 2023 and 2022, respectively. The following table summarizes the restructuring charges recorded for the years ended December 31, 2024, 2023 and 2022 by operating segment: Year Ended December 31, 2024 2023 2022 (in millions) Signal and Power Solutions $ 140 $ 82 $ 30 Advanced Safety and User Experience 53 129 55 Total $ 193 $ 211 $ 85 The table below summarizes the activity in the restructuring liability for the years ended December 31, 2024 and 2023: Employee Termination Benefits Liability Other Exit Costs Liability Total (in millions) Accrual balance at January 1, 2023 $ 83 $ — $ 83 Provision for estimated expenses incurred during the year 211 — 211 Payments made during the year (128) — (128) Foreign currency and other 1 — 1 Accrual balance at December 31, 2023 $ 167 $ — $ 167 Provision for estimated expenses incurred during the year $ 193 $ — $ 193 Payments made during the year (238) — (238) Foreign currency and other (4) — (4) Accrual balance at December 31, 2024 $ 118 $ — $ 118

General, in December 2024, Old Aptiv established a new publicly-listed Jersey parent company, New Aptiv, which is resident for tax purposes in Switzerland. Following consummation of the Transaction, Old Aptiv became a wholly-owned subsidiary of New Aptiv and New Aptiv was renamed “Aptiv PLC.” Old Aptiv merged with and into Aptiv Swiss Holdings, a newly formed Jersey incorporated private limited company, and a direct, wholly-owned subsidiary of New Aptiv, with Aptiv Swiss Holdings surviving as a direct, wholly owned subsidiary of New Aptiv, and Old Aptiv ceasing to exist. Except as otherwise noted, all property, rights, privileges, powers and franchises of Old Aptiv vested in Aptiv Swiss Holdings, and all debts, liabilities and duties of Old Aptiv became debts, liabilities and duties of Aptiv Swiss Holdings. In connection with the Transaction, Aptiv Swiss Holdings (i) entered into a supplemental indenture to each indenture in which Aptiv Swiss Holdings assumed all of Old Aptiv’s obligations under each series of Old Aptiv’s outstanding Notes and (ii) entered into an assumption and/or supplement agreement relating to each Credit Agreement in which New Aptiv assumed all of Old Aptiv’s obligations under each Credit Agreement as the “parent entity” thereunder. In addition, New Aptiv (i) entered into a supplemental indenture to each indenture in which New Aptiv guaranteed the outstanding Notes and (ii) entered into a guarantee joinder relating to each Credit Agreement in which New Aptiv guaranteed the obligations under each Credit Agreement. Following the reorganization transaction, Aptiv Swiss Holdings replaced Old Aptiv as an obligor under the Credit Agreements, the senior notes and the junior notes, and New Aptiv became a guarantor under the Credit Agreements (and will act as the “parent entity” thereunder) and the indentures. Credit Agreement Aptiv PLC and its wholly-owned subsidiary Aptiv Corporation entered into a credit agreement (the “Credit Agreement”) with, among others, JPMorgan Chase Bank, N.A., as administrative agent (the “Administrative Agent”), under which it maintains a senior unsecured credit facility currently consisting of a revolving credit facility of $2 billion (the “Revolving Credit Facility”). The Revolving Credit Facility matures on June 24, 2026. Aptiv Global Financing Designated Activity Company (“AGF DAC,” formerly known as Aptiv Global Financing Limited), a wholly-owned subsidiary of Aptiv PLC, previously executed a joinder agreement to the Credit Agreement, which allows it to act as a borrower under the Credit Agreement, and a guaranty supplement, under which AGF DAC guarantees the obligations under the Credit Agreement, subject to certain exceptions. As a result of the reorganization transaction, Aptiv Swiss Holdings replaced Old Aptiv as an obligor under the Credit Agreement. The Credit Agreement was entered into in March 2011 and has been subsequently amended and restated on several occasions, most recently on June 24, 2021, and was further amended on April 19, 2023. The June 2021 amendment, among other things, (1) refinanced and replaced the term loan A and revolver with a new term loan A with an original maturity in 2026, and a new five-year revolving credit facility with aggregate commitments of $2 billion, (2) utilized the Company’s existing sustainability-linked metrics and commitments, that, if achieved, would change the facility fee and interest rate margins as described below, and (3) established the leverage ratio maintenance covenant that requires the Company to maintain total net leverage (as calculated in accordance with the Credit Agreement) of less than 3.5 to 1.0 (or 4.0 to 1.0 for four full fiscal quarters following completion of material acquisitions, as defined in the Credit Agreement) and allowed for dividends and other payments on equity. Effective from the date of the April 2023 amendment, all interest rate benchmarks within the Credit Agreement that were previously based on the London Interbank Offered Rate were transitioned to a rate based on the Secured Overnight Financing Rate (“SOFR”). The Credit Agreement also contains an accordion feature that permits Aptiv to increase, from time to time, the aggregate borrowing capacity under the Credit Agreement by up to an additional $1 billion upon Aptiv’s request, the agreement of the lenders participating in the increase, and the approval of the Administrative Agent. Borrowings under the Credit Agreement are prepayable at Aptiv’s option without premium or penalty. As of December 31, 2024, Aptiv had no amounts outstanding under the Revolving Credit Facility and approximately $2 million in letters of credit were issued under the Credit Agreement. Letters of credit issued under the Credit Agreement reduce availability under the Revolving Credit Facility. Loans under the Credit Agreement bear interest, at Aptiv’s option, at either (a) the Administrative Agent’s Alternate Base Rate (“ABR” as defined in the Credit Agreement) or (b) SOFR plus in either case a percentage per annum as set forth in the table below (the “Applicable Rate”). The rates under the Credit Agreement on the specified dates are set forth below: December 31, 2024 December 31, 2023 SOFR plus ABR plus SOFR plus ABR plus Revolving Credit Facility 1.06 % 0.06 % 1.06 % 0.06 % The Applicable Rate under the Credit Agreement, as well as the facility fee, may increase or decrease from time to time based on changes in the Company’s credit ratings and whether the Company achieves or fails to achieve certain sustainability-linked targets with respect to greenhouse gas emissions and workplace safety. Such adjustments may be up to 0.04% per annum on interest rate margins on the Revolving Credit Facility, 0.02% per annum on interest rate margins on the Tranche A Term Loan (prior to its repayment, as described above) and 0.01% per annum on the facility fee. Accordingly, the interest rate is subject to fluctuation during the term of the Credit Agreement based on changes in the ABR, SOFR, changes in the Company’s corporate credit ratings or whether the Company achieves or fails to achieve its sustainability-linked targets. The Credit Agreement also requires that Aptiv pay certain facility fees on the Revolving Credit Facility, which are also subject to adjustment based on the sustainability-linked targets as described above, and certain letter of credit issuance and fronting fees. The Company achieved the sustainability-linked targets for the 2023 calendar year, and the interest rate margins and facility fees were reduced from the Applicable Rates, by the amounts specified above, effective in the third quarter of 2024. The Credit Agreement contains certain covenants that limit, among other things, the Company’s (and the Company’s subsidiaries’) ability to incur certain additional indebtedness or liens or to dispose of substantially all of its assets. In addition, the Credit Agreement requires that the Company maintain a consolidated leverage ratio (the ratio of Consolidated Total Indebtedness to Consolidated EBITDA, each as defined in the Credit Agreement) of not more than 3.5 to 1.0 (or 4.0 to 1.0 for four full fiscal quarters following completion of material acquisitions, as defined in the Credit Agreement). The Credit Agreement also contains events of default customary for financings of this type. The Company was in compliance with the Credit Agreement covenants as of December 31, 2024. As of December 31, 2024, all obligations under the Credit Agreement were borrowed by Aptiv Corporation and jointly and severally guaranteed by AGF DAC, Aptiv PLC and Aptiv Swiss Holdings, subject to certain exceptions set forth in the Credit Agreement. Previously, the Company also maintained a senior unsecured credit facility in the form of a term loan (the “Tranche A Term Loan”). On October 27, 2023, the Company fully repaid the outstanding principal balance of $301 million on the Tranche A Term Loan, utilizing cash on hand. As a result, Aptiv recognized a loss on debt extinguishment of approximately $1 million during the year ended December 31, 2023 within other income (expense), net in the consolidated statements of operations. Bridge Credit Agreement On August 1, 2024, Aptiv PLC and certain of its subsidiaries entered into a $2.5 billion senior unsecured bridge facility under a Bridge Credit Agreement (the “Bridge Credit Agreement”) with JPMorgan Chase Bank, N.A., as administrative agent, JPMorgan Chase Bank, N.A. and Goldman Sachs Lending Partners LLC, as joint lead arrangers and joint bookrunners, and Goldman Sachs Lending Partners LLC, as syndication agent. The proceeds of the loans under the Bridge Credit Agreement were utilized to provide initial funding for a portion of the share repurchases under the accelerated share repurchase program, as further described in Note 15. Shareholders’ Equity and Net Income Per Share. Aptiv incurred approximately $17 million of issuance costs in connection with the Bridge Credit Agreement. The loans available under the Bridge Credit Agreement were fully drawn on August 1. The Bridge Credit Agreement was fully repaid and terminated during the third quarter of 2024 using proceeds from the Term Loan A and proceeds from the issuance of the 2024 Senior Notes and 2024 Junior Notes, as described below. As a result of the repayment of the Bridge Credit Agreement, Aptiv recognized a loss on debt extinguishment of approximately $11 million during the year ended December 31, 2024, within other income (expense), net in the consolidated statements of operations. Term Loan A Credit Agreement On August 19, 2024, Aptiv PLC and its wholly-owned subsidiaries AGF DAC and Aptiv Corporation entered into a new senior unsecured term loan A credit agreement (the “Term Loan A Credit Agreement”) with, among others, JPMorgan Chase Bank, N.A., as Administrative Agent, under which it maintains a senior unsecured credit facility consisting of a term loan (the “Term Loan A”) in aggregate principal amount of $600 million. Aptiv incurred approximately $2 million of issuance costs in connection with the Term Loan A. As described above, proceeds from the Term Loan A were used to repay a portion of the loans incurred under the Bridge Credit Agreement during the three months ended September 30, 2024. This transaction was accounted for as a modification of debt in accordance with ASC Topic 470-50, Debt Modifications and Extinguishments . Accordingly, a pro-rata portion of the unamortized fees from the Bridge Credit Agreement in the amount of $4 million was transferred to the Term Loan A and, together with the $2 million of direct issuance costs referenced above, will be amortized to interest expense over the term of the Term Loan A. On December 20, 2024, the Company repaid $350 million of the outstanding principal balance on the Term Loan A, utilizing cash on hand. As a result, Aptiv recognized a loss on debt extinguishment of approximately $3 million during the year ended December 31, 2024 within other income (expense), net in the consolidated statements of operations. The Term Loan A matures on August 19, 2027. Borrowings under the Term Loan A Credit Agreement are prepayable at Aptiv’s option without premium or penalty. No principal payment is required until the outstanding principal amount is due in full on the maturity date. In the first quarter of 2025, the Company fully repaid the remaining outstanding principal balance of $250 million on the Term Loan A, utilizing cash on hand. Loans under the Term Loan A Credit Agreement bear interest, at Aptiv’s option, at either (a) ABR or (b) SOFR plus in either case a percentage per annum as set forth in the table below (the “Term Loan Applicable Rate”).

Retirement Benefits [Abstract]
Pension Benefits	PENSION BENEFITS Certain of Aptiv’s non-U.S. subsidiaries sponsor defined benefit pension plans, which generally provide benefits based on negotiated amounts for each year of service. Aptiv’s primary non-U.S. plans are located in France, Germany, Mexico, Portugal and the United Kingdom (“U.K.”). The U.K. and certain Mexican plans are funded. In addition, Aptiv has defined benefit plans in South Korea, Turkey and Italy for which amounts are payable to employees immediately upon separation. The obligations for these plans are recorded over the requisite service period. Aptiv sponsors a Supplemental Executive Retirement Program (“SERP”) for those employees who were U.S. executives of the former Delphi Corporation prior to September 30, 2008 and were still U.S. executives of the Company on October 7, 2009, the effective date of the program. This program is unfunded. Executives receive benefits over five years after an involuntary or voluntary separation from Aptiv. The SERP is closed to new members. Funded Status The amounts shown below reflect the change in the U.S. defined benefit pension obligations during 2024 and 2023. Year Ended December 31, 2024 2023 (in millions) Benefit obligation at beginning of year $ 2 $ 3 Benefits paid (1) (1) Benefit obligation at end of year $ 1 $ 2 Change in plan assets: Fair value of plan assets at beginning of year $ — $ — Aptiv contributions 1 1 Benefits paid (1) (1) Fair value of plan assets at end of year $ — $ — Underfunded status $ (1) $ (2) Amounts recognized in the consolidated balance sheets consist of: Current liabilities $ — $ (1) Long-term liabilities (1) (1) Total $ (1) $ (2) Amounts recognized in accumulated other comprehensive loss consist of (pre-tax): Actuarial loss $ 2 $ 3 Total $ 2 $ 3 The amounts shown below reflect the change in the non-U.S. defined benefit pension obligations during 2024 and 2023.

The projected benefit obligation (“PBO”), accumulated benefit obligation (“ABO”), and fair value of plan assets for pension plans with accumulated benefit obligations in excess of plan assets and with plan assets in excess of accumulated benefit obligations are as follows: U.S. Plans Non-U.S. Plans 2024 2023 2024 2023 (in millions) PBO $ 1 $ 2 $ 465 $ 521 ABO $ 1 $ 2 $ 417 $ 462 Fair value of plan assets at end of year $ — $ — $ 77 $ 90 Plans with Plan Assets in Excess of ABO PBO $ — $ — $ 196 $ 225 ABO $ — $ — $ 186 $ 214 Fair value of plan assets at end of year $ — $ — $ 222 $ 251 Total PBO $ 1 $ 2 $ 661 $ 746 ABO $ 1 $ 2 $ 603 $ 676 Fair value of plan assets at end of year $ — $ — $ 299 $ 341 Benefit costs presented below were determined based on actuarial methods and included the following: U.S. Plans Year Ended December 31, 2024 2023 2022 (in millions) Amortization of actuarial losses $ 1 $ 1 $ 1 Net periodic benefit cost $ 1 $ 1 $ 1 Non-U.S. Plans Year Ended December 31, 2024 2023 2022 (in millions) Service cost $ 18 $ 16 $ 15 Interest cost 39 39 23 Expected return on plan assets (17) (15) (17) Settlement loss 2 2 — Amortization of actuarial losses 1 1 8 Net periodic benefit cost $ 43 $ 43 $ 29 Other postretirement benefit obligations were approximately $1 million at December 31, 2024 and 2023. Experience gains and losses, as well as the effects of changes in actuarial assumptions and plan provisions are recognized in other comprehensive income. Cumulative actuarial gains and losses in excess of 10% of the PBO for a particular plan are amortized over the average future service period of the employees in that plan. The principal assumptions used to determine the pension expense and the actuarial value of the projected benefit obligation for the U.S. and non-U.S. pension plans were: Assumptions used to determine benefit obligations at December 31: Pension Benefits U.S. Plans Non-U.S. Plans 2024 2023 2024 2023 Weighted-average discount rate 4.90 % 5.50 % 6.23 % 5.91 % Weighted-average rate of increase in compensation levels N/A N/A 2.66 % 2.93 % Assumptions used to determine net expense for years ended December 31: Pension Benefits U.S. Plans Non-U.S. Plans 2024 2023 2022 2024 2023 2022 Weighted-average discount rate 5.50 % 5.20 % 1.90 % 5.91 % 5.95 % 3.09 % Weighted-average rate of increase in compensation levels N/A N/A N/A 2.93 % 2.82 % 2.47 % Weighted-average expected long-term rate of return on plan assets N/A N/A N/A 5.18 % 4.98 % 4.46 % Aptiv selects discount rates by analyzing the results of matching each plan’s projected benefit obligations with a portfolio of high-quality fixed income investments rated AA or higher by Standard and Poor’s or Moody’s. Aptiv does not have any U.S. pension assets; therefore no U.S. asset rate of return calculation was necessary. The primary funded non-U.S. plans are in the U.K. and Mexico. For the determination of 2024 expense, Aptiv assumed a long-term expected asset rate of return of approximately 4.50% and 8.00% for the U.K. and Mexico, respectively. Aptiv evaluated input from local actuaries and asset managers, including consideration of recent fund performance and historical returns, in developing the long-term rate of return assumptions. The assumptions for the U.K. and Mexico are primarily conservative long-term, prospective rates. To determine the expected return on plan assets, the market-related value of our plan assets is actual fair value. Aptiv’s pension expense for 2025 is determined at the 2024 year end measurement date. For purposes of analysis, the following table highlights the sensitivity of the Company’ pension obligations and expense attributable to changes in key assumptions: Change in Assumption Impact on Impact on PBO 25 basis point (“bp”) decrease in discount rate Less than + $1 million ‘ + $15 million 25 bp increase in discount rate Less than + $1 million ‘ - $15 million 25 bp decrease in long-term expected return on assets ‘ + $1 million — 25 bp increase in long-term expected return on assets ‘ - $1 million — The above sensitivities reflect the effect of changing one assumption at a time. It should be noted that economic factors and conditions often affect multiple assumptions simultaneously and the effects of changes in key assumptions are not necessarily linear. The above sensitivities also assume no changes to the design of the pension plans and no major restructuring programs. Pension Funding The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid: Projected Pension Benefit Payments U.S. Plans Non-U.S. Plans (in millions) 2025 $ — $ 52 2026 $ 1 $ 46 2027 $ — $ 50 2028 $ — $ 53 2029 $ — $ 55 2030 – 2034 $ — $ 316 Aptiv anticipates making pension contributions and benefit payments of approximately $22 million in 2025. Aptiv sponsors defined contribution plans for certain hourly and salaried employees. Expense related to the contributions for these plans was $38 million, $42 million, and $39 million for the years ended December 31, 2024, 2023 and 2022, respectively. Plan Assets Certain pension plans sponsored by Aptiv invest in a diversified portfolio consisting of an array of asset classes that attempts to maximize returns while minimizing volatility. These asset classes include developed market equities, emerging market equities, private equity, global high quality and high yield fixed income, real estate and absolute return strategies. The fair values of Aptiv’s pension plan assets weighted-average asset allocations at December 31, 2024 and 2023, by asset category, are as follows: Fair Value Measurements at December 31, 2024 Asset Category Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (in millions) Cash, cash equivalents and repurchase agreements (1) $ (55) $ 4 $ (59) $ — Time deposits 31 — 31 — Equity mutual funds 20 — 20 — Bond mutual funds 180 124 56 — Real estate trust funds 19 — — 19 Private debt funds 19 — — 19 Insurance contracts 1 — — 1 Debt securities 49 49 — — Equity securities 35 35 — — Total $ 299 $ 212 $ 48 $ 39 (1) Level 2 includes repurchase agreements of $64 million within non-U.S. plans.

Following is a description of the valuation methodologies used for pension assets measured at fair value. Repurchase agreements —Due to the short-term nature of repurchase agreements, fair value is estimated as the outstanding balance of the obligation. Time deposits —The fair value of fixed-maturity certificates of deposit was estimated using the rates offered for deposits of similar remaining maturities. Equity mutual funds —The fair value of the equity mutual funds is determined by the indirect quoted market prices on regulated financial exchanges of the underlying investments included in the fund. Bond mutual funds —The fair value of the bond mutual funds is determined by the indirect quoted market prices on regulated financial exchanges of the underlying investments included in the fund. Real estate —The fair value of real estate properties is estimated using an annual appraisal provided by the administrator of the property investment. Management believes this is an appropriate methodology to obtain the fair value of these assets. Private debt funds —The fair value of the private debt funds is determined by the fund administrator based on available market quotes on the subject securities or an income approach valuation in order to estimate fair value. Management believes this is an appropriate methodology to obtain the fair value of these assets. Insurance contracts —The insurance contracts are invested in a fund with guaranteed minimum returns. The fair values of these contracts are based on the net asset value underlying the contracts.

Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES Ordinary Business Litigation Aptiv is from time to time subject to various legal actions and claims incidental to its business, including those arising out of alleged defects, alleged breaches of contracts, product warranties, intellectual property matters, and employment-related matters. It is the opinion of Aptiv that the outcome of such matters will not have a material adverse impact on the consolidated financial position, results of operations, or cash flows of Aptiv. With respect to warranty matters, although Aptiv cannot ensure that the future costs of warranty claims by customers will not be material, Aptiv believes its established reserves are adequate to cover potential warranty settlements. Environmental Matters Aptiv is subject to the requirements of U.S. federal, state, local and non-U.S. environmental, health and safety laws and regulations. As of December 31, 2024 and 2023, the undiscounted reserve for environmental investigation and remediation recorded in other liabilities was approximately $4 million. Aptiv cannot ensure that environmental requirements will not change or become more stringent over time or that its eventual environmental remediation costs and liabilities will not exceed the amount of its current reserves. In the event that such liabilities were to significantly exceed the amounts recorded, Aptiv’s results of operations could be materially affected. At December 31, 2024, the difference between the recorded liabilities and the reasonably possible range of potential loss was not material.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES In connection with the change of tax residency described in Note 1. General, in December 2024, Aptiv established a new publicly-listed Jersey parent company, New Aptiv, which is resident for tax purposes in Switzerland. Following consummation of the Transaction, Aptiv PLC became a wholly-owned subsidiary of New Aptiv and New Aptiv was renamed “Aptiv PLC.” Income before income taxes and equity income for U.S. and non-U.S. operations are as follows: Year Ended December 31, 2024 2023 2022 (in millions) U.S. (loss) income $ (78) $ (162) $ 24 Non-U.S. income 2,229 1,499 966 Income before income taxes and equity loss $ 2,151 $ 1,337 $ 990 The provision (benefit) for income taxes is comprised of: Year Ended December 31, 2024 2023 2022 (in millions) Current income tax expense (benefit): U.S. federal $ (25) $ 25 $ 45 Non-U.S. 277 208 205 U.S. state and local 5 3 15 Total current 257 236 265 Deferred income tax expense (benefit), net: U.S. federal (67) (62) (43) Non-U.S. 35 (2,091) (90) U.S. state and local (2) (11) (11) Total deferred (34) (2,164) (144) Total income tax provision (benefit) $ 223 $ (1,928) $ 121 Cash paid or withheld for income taxes was $249 million, $307 million and $194 million for the years ended December 31, 2024, 2023 and 2022, respectively. For purposes of comparability and consistency, the Company uses the notional U.S. federal income tax rate when presenting the Company’s reconciliation of the income tax provision. The Company is a Swiss resident taxpayer as of December 31, 2024. Prior to December 2024, the Company was an Irish resident taxpayer. A reconciliation of the provision for income taxes compared with the amounts at the notional U.S. federal statutory rate was: Year Ended December 31, 2024 2023 2022 (in millions) Notional U.S. federal income taxes at statutory rate $ 452 $ 281 $ 208 Income taxed at other rates (236) (131) (61) Change in valuation allowance (12) 1 (63) Other change in tax reserves 16 (7) 10 Intercompany reorganizations (27) (2,082) — Withholding taxes 62 57 38 Tax credits (32) (19) (19) Change in tax law — (17) — Other adjustments — (11) 8 Total income tax expense (benefit) $ 223 $ (1,928) $ 121 Effective tax rate 10 % (144) % 12 % The Company’s tax rate is affected by the fact that its parent entity was an Irish resident taxpayer and became a Swiss resident tax payer in December 2024, the tax rates in Ireland, Switzerland 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. Included in the non-U.S. income taxed at other rates are tax incentives obtained in various non-U.S. countries, primarily the High and New Technology Enterprise (“HNTE”) status in China and various incentives in Morocco, which totaled $27 million in 2024, $23 million in 2023 and $12 million in 2022, as well as tax benefit for income earned, and no tax benefit for losses incurred, in jurisdictions where a valuation allowance has been recorded. The Company currently benefits from tax holidays in various non-U.S. jurisdictions with expiration dates from 2025 through 2044. The income tax benefits attributable to these tax holidays are approximately $5 million ($0.02 per share) in 2024, $7 million ($0.03 per share) in 2023 and $3 million (less than $0.01 per share) in 2022. The effective tax rate in the year ended December 31, 2024 includes discrete tax benefits primarily associated with intercompany reorganizations. Also included as a discrete item in the effective tax rate for the year ended December 31, 2024 is the beneficial impact of approximately 4 points resulting from the Motional funding and ownership restructuring transactions, as described further in Note 5. Investments in Affiliates. There was no tax expense associated with these gains as Aptiv’s interest in Motional is exempt from capital gains tax in the jurisdiction in which it is owned. The effective tax rate in the year ended December 31, 2023 was primarily impacted by the Company’s transfers of intellectual property, as described below. The effective tax rate in the year ended December 31, 2022 was impacted by favorable changes in valuation allowances offset by changes in reserves and provision to return adjustments. The effective tax rate was also impacted by impairments and charges related to our exit from our former majority owned Russian subsidiary and other charges in Ukraine for which no tax benefit was recognized. On December 15, 2022, the European Union (the “E.U.”) Member States formally adopted the Pillar Two Framework, which generally provides for a minimum effective tax rate of 15%, as established by the Organisation for Economic Co-operation and Development (the “OECD”). Many countries have enacted legislation consistent with the Framework effective at the beginning of 2024. The OECD continues to release additional guidance on these rules. The Company has proactively responded to these tax policy changes, as described below, and will continue to closely monitor developments. Our effective tax rate for the year ended December 31, 2024 includes an unfavorable impact from the enacted Framework. The Tax Cuts and Jobs Act, which was enacted in the U.S. in 2017, created a provision known as Global Intangible Low-Taxed Income (“GILTI”) that imposes a tax on certain earnings of foreign subsidiaries. U.S. GAAP allows companies to make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or to provide for the tax expense related to GILTI in the year the tax is incurred. We have elected to account for GILTI in the year the tax is incurred. As described above, certain of the Company’s Chinese subsidiaries benefit from a reduced corporate income tax rate as a result of their HNTE status. Aptiv regularly submits applications to reapply for HNTE status as they expire. The Company believes each of the applicable entities will continue to renew HNTE status going forward and has reflected this in calculating total income tax expense. Intellectual Property Transfer In response to the Framework, the Company initiated changes to its corporate entity structure, including intercompany transfers of certain intellectual property to one of its subsidiaries in Switzerland, during the second half of 2023. The Company transferred certain intellectual property during the year ended December 31, 2023 between wholly-owned legal entities in different tax jurisdictions. These transfers were intercompany transactions. Consequently, the resulting gains on these transfers were eliminated for purposes of the consolidated financial statements. However, certain of these transfers resulted in a gain that is subject to income tax in the local jurisdiction, which was offset with the utilization of existing net operating loss carryforwards. A portion of the net operating loss carryforwards were previously reduced by deferred tax liabilities from recapturable deductions, which were eliminated as part of the intercompany transactions, while the remaining net operating loss carryforwards were largely offset by a valuation allowance. Consequently, during the year ended December 31, 2023, the Company recognized a net deferred tax expense of approximately $55 million, which is comprised of deferred tax benefits of approximately $2,075 million related to the release of valuation allowances as a result of the transfers and deferred tax expense of approximately $2,130 million to reflect utilization of the loss carryforwards. As a result of the intellectual property transfers during the year ended December 31, 2023, the Company’s Swiss subsidiary, which received the intellectual property, recognized a step-up in tax basis on the fair value of the transferred intellectual property. This resulted in the creation of a temporary difference between the book basis and tax basis of the specified intellectual property. Consequently, the Company recorded a deferred tax benefit of approximately $1,820 million during the year ended December 31, 2023, which was increased from the amounts disclosed as of September 30, 2023, primarily as a result of additional intellectual property transfers in the fourth quarter of 2023. Furthermore, the Company’s Swiss subsidiary was granted a ten-year tax incentive, beginning in 2024. A deferred tax benefit of approximately $330 million, net of a valuation allowance, was recorded during the year ended December 31, 2023 to reflect the estimated future reductions in tax associated with the incentive. This amount was increased from the amount disclosed as of September 30, 2023, primarily as a result of changes in the estimated utilization of the tax incentive from the additional transfers of intellectual property in the fourth quarter of 2023. The total income tax benefit recorded as a result of the intercompany transfers of intellectual property and negotiated tax incentive, all as described above, combined with related additional current year tax expense as a result of the transactions, was approximately $2,080 million during the year ended December 31, 2023. The measurement of certain deferred tax assets, as described above, and associated income tax benefits resulting from these transactions was impacted by tax legislation in Switzerland enacted in the fourth quarter of 2023, which increased the statutory income tax rate, resulting in additional deferred tax benefit impacts of approximately $365 million, net of valuation allowances (which are reflected in the amounts above), during the three months ended December 31, 2023, from the amounts disclosed as of September 30, 2023. Deferred Income Taxes The Company accounts for income taxes and the related accounts under the liability method. Deferred income tax assets and liabilities reflect the impact of temporary differences between amounts of assets and liabilities for financial reporting purposes and the bases of such assets and liabilities as measured by tax laws. Significant components of the deferred tax assets and liabilities are as follows: December 31, 2024 2023 (in millions) Deferred tax assets: Pension $ 61 $ 73 Employee benefits 57 54 Net operating loss carryforwards 578 1,756 Warranty and other liabilities 72 85 Operating lease liabilities 109 126 Capitalized R&D 110 125 Tax credit carryforwards 1,605 1,597 Intangibles 1,634 1,773 Other 175 193 Total gross deferred tax assets 4,401 5,782 Less: valuation allowances (1,704) (3,032) Total deferred tax assets (1) $ 2,697 $ 2,750 Deferred tax liabilities: Fixed assets $ 27 $ 49 Tax on unremitted profits of certain foreign subsidiaries 82 74 Intangibles 496 550 Operating lease right-of-use assets 101 120 Total gross deferred tax liabilities 706 793 Net deferred tax assets $ 1,991 $ 1,957 (1) Reflects gross amount before jurisdictional netting of deferred tax assets and liabilities. Deferred tax assets and liabilities are classified as long-term in the consolidated balance sheets. Net deferred tax assets and liabilities are included in the consolidated balance sheets as follows: December 31, 2024 2023 (in millions) Long-term assets $ 2,281 $ 2,351 Long-term liabilities (290) (394) Total deferred tax asset $ 1,991 $ 1,957 The net deferred tax asset of $1,991 million as of December 31, 2024 is primarily comprised of deferred tax asset amounts in Switzerland, Mexico, Brazil and India, partially offset by deferred tax liabilities primarily in the U.S., Italy, Luxembourg and Ireland. Net Operating Loss and Tax Credit Carryforwards As of December 31, 2024, the Company has gross deferred tax assets of approximately $553 million for non-U.S. net operating loss (“NOL”) carryforwards with recorded valuation allowances of $368 million. These NOLs are available to offset future taxable income and realization is dependent on generating sufficient taxable income prior to expiration of the loss carryforwards. The NOLs primarily relate to Luxembourg, Poland, Switzerland, Germany, the U.K. and France. The NOL carryforwards have expiration dates ranging from one year to an indefinite period. Deferred tax assets include $1,605 million and $1,597 million of tax credit carryforwards with recorded valuation allowances of $1,267 million and $1,263 million at December 31, 2024 and 2023, respectively. The tax credits are primarily related to Switzerland and the U.S. These tax credit carryforwards expire at various times from 2025 through 2044. OECD Pillar Two Framework Amendment On January 15, 2025, the OECD released Administrative Guidance (the “Guidance) on Article 9.1 of the Global Anti-Base Erosion Model Rules (the “Model Rules”) which amends the Pillar Two Framework. Jurisdictions that have adopted the Framework may implement and administer their domestic laws consistent with the Model Rules and guidance. The Guidance eliminates the tax basis in certain deferred tax assets and tax credit carryforwards for purposes of global minimum tax established under the Framework. This Guidance may lead to an adjustment to the tax incentive granted to the Company’s Swiss subsidiary in 2023 under the terms of the incentive agreement and a reduction of deferred tax assets of up to approximately $300 million, net of valuation allowance. The Company is continuing to analyze the impacts of the Guidance and will recognize any resulting provisions in the first quarter of 2025. Cumulative Undistributed Foreign Earnings No income taxes have been provided on indefinitely reinvested earnings of certain foreign subsidiaries at December 31, 2024. Taxes of $82 million have been accrued on undistributed earnings that are not indefinitely reinvested and are primarily related to China, Honduras, Morocco and Germany. As of December 31, 2024, taxes have not been provided on approximately $624 million of temporary differences related to undistributed earnings in various subsidiaries as those earnings have been indefinitely invested. If, in the future, these earnings were to be repatriated to Switzerland, additional tax provisions would be required. It is not practicable to determine the unrecognized deferred tax liability on these temporary differences. There are no other material liabilities for income taxes on the undistributed earnings of foreign subsidiaries, as the Company has concluded that such earnings are either indefinitely reinvested or should not give rise to additional income tax liabilities as a result of the distribution of such earnings. Uncertain Tax Positions The Company recognizes tax benefits only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Unrecognized tax benefits are tax benefits claimed in the Company’s tax returns that do not meet these recognition and measurement standards. A reconciliation of the gross change in the unrecognized tax benefits balance, excluding interest and penalties is as follows: Year Ended December 31, 2024 2023 2022 (in millions) Balance at beginning of year $ 222 $ 224 $ 224 Additions related to current year 3 4 12 Additions related to prior years 14 11 29 Reductions related to prior years (9) (12) (33) Reductions due to expirations of statute of limitations (1) (2) (7) Settlements (2) (3) (1) Balance at end of year $ 227 $ 222 $ 224 A portion of the Company’s unrecognized tax benefits would, if recognized, reduce its effective tax rate. The remaining unrecognized tax benefits relate to tax positions that, if recognized, would result in an offsetting change in valuation allowance and for which only the timing of the benefit is uncertain. Recognition of these tax benefits would reduce the Company’s effective tax rate only through a reduction of accrued interest and penalties. As of December 31, 2024 and 2023, the amounts of unrecognized tax benefit that would reduce the Company’s effective tax rate were $196 million and $185 million, respectively. For 2024 and 2023, respectively, $92 million and $74 million of reserves for uncertain tax positions would be offset by the write-off of a related deferred tax asset, if recognized. The Company recognizes interest and penalties relating to unrecognized tax benefits as part of income tax expense. Total accrued liabilities for interest and penalties were $31 million and $27 million at December 31, 2024 and 2023, respectively. Total interest and penalties recognized as part of income tax expense were an expense of $6 million, expense of $1 million, and benefit of $2 million for the years ended December 31, 2024, 2023 and 2022, respectively. The Company files tax returns in multiple jurisdictions and is subject to examination by taxing authorities throughout the world. Taxing jurisdictions significant to Aptiv include China, Germany, Ireland, Mexico, South Korea, Switzerland, the U.K. and the U.S. Open tax years related to these taxing jurisdictions remain subject to examination and could result in additional tax liabilities. In general, the Company’s affiliates are no longer subject to income tax examinations by foreign tax authorities for years before 2002. It is reasonably possible that audit settlements, the conclusion of current examinations or the expiration of the statute of limitations in several jurisdictions could impact the Company’s unrecognized tax benefits. A reversal of approximately $10 million is reasonably possible in the next 12 months, due to the running of statutes of limitations in various taxing jurisdictions. Pledged Assets

Shareholders' Equity and Net Income Per Share Note [Abstract]
Shareholders' Equity And Net Income Per Share	SHAREHOLDERS’ EQUITY AND NET INCOME PER SHARE Change of Tax Residency In connection with the reorganization transaction as further described in Note 1. General, in December 2024, Old Aptiv established a new publicly-listed Jersey parent company, New Aptiv, which is resident for tax purposes in Switzerland. As a result of the Transaction, all issued and outstanding ordinary shares of Old Aptiv were exchanged on a one-for-one basis for newly issued ordinary shares of New Aptiv. Following consummation of the Transaction, holders of Old Aptiv shares became ordinary shareholders of New Aptiv, Old Aptiv became a wholly-owned subsidiary of New Aptiv and New Aptiv was renamed “Aptiv PLC.” Old Aptiv merged with and into Aptiv Swiss Holdings, a newly formed Jersey incorporated private limited company, and a direct, wholly-owned subsidiary of New Aptiv, with Aptiv Swiss Holdings surviving as a direct, wholly owned subsidiary of New Aptiv, and Old Aptiv ceasing to exist. Conversion of the MCPS On June 15, 2023, (the “Mandatory Conversion Date”), each outstanding share of the Company’s 5.50% Mandatory Convertible Preferred Shares, Series A, $0.01 par value per share (the “MCPS”) converted into 1.0754 ordinary shares of the Company. In aggregate, the MCPS converted into approximately 12.37 million ordinary shares of the company, pursuant to the Statement of Rights governing the MCPS. The number of the Company’s ordinary shares issued upon conversion was determined based on the volume-weighted average price per share of the Company’s ordinary shares over the 20 consecutive trading day period beginning on, and including, the 21st scheduled trading day immediately before the Mandatory Conversion Date. Prior to their conversion, holders of the MCPS were entitled to receive, when and if declared by the Company’s Board of Directors, cumulative dividends at the annual rate of 5.50% of the liquidation preference of $100 per share (equivalent to $5.50 annually per share), payable in cash or, subject to certain limitations, by delivery of the Company’s ordinary shares or any combination of cash and the Company’s ordinary shares, at the Company’s election. Dividends on the MCPS were payable quarterly on March 15, June 15, September 15 and December 15 of each year (commencing on September 15, 2020 to, and including June 15, 2023), to the holders of record of the MCPS as they appear on the Company’s share register at the close of business on the immediately preceding March 1, June 1, September 1 and December 1, respectively. Net Income Per Share Basic net income per share is computed by dividing net income attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period. Diluted net income per share reflects the weighted average dilutive impact of all potentially dilutive securities from the date of issuance and is computed using the treasury stock and if-converted methods. Prior to the conversion of the MCPS into ordinary shares in June 2023, the if-converted method was used to determine if the impact of the conversion of the MCPS into ordinary shares was more dilutive than the MCPS dividends to net income per share. If so, the MCPS were assumed to have been converted at the later of the beginning of the period or the time of issuance, and the resulting ordinary shares were included in the denominator and the MCPS dividends were added back to the numerator. Unless otherwise noted, share and per share amounts included in these notes are on a diluted basis. For the year ended December 31, 2023, the calculation of net income per share includes the dilutive impacts of the MCPS under the if-converted method. For the year ended December 31, 2022, the impact of the MCPS calculated under the if-converted method was anti-dilutive, and as such 12.37 million ordinary shares underlying the MCPS were excluded from the diluted net income per share calculation. For all periods presented, the calculation of net income per share also contemplates the dilutive impacts, if any, of the Company’s share-based compensation plans. Refer to Note 21. Share-Based Compensation for additional information. Weighted Average Shares The following table illustrates net income per share attributable to ordinary shareholders and the weighted average shares outstanding used in calculating basic and diluted income per share: Year Ended December 31, 2024 2023 2022 (in millions, except per share data) Numerator, basic: Net income attributable to ordinary shareholders $ 1,787 $ 2,909 $ 531 Numerator, diluted: Net income attributable to Aptiv $ 1,787 $ 2,938 $ 594 MCPS dividends (1) — — (63) Numerator, diluted $ 1,787 $ 2,938 $ 531 Denominator: Weighted average ordinary shares outstanding, basic 256.38 276.92 270.90 Dilutive shares related to RSUs 0.28 0.17 0.28 Weighted average MCPS converted shares (1) — 5.79 — Weighted average ordinary shares outstanding, including dilutive shares 256.66 282.88 271.18 Net income per share attributable to ordinary shareholders: Basic $ 6.97 $ 10.50 $ 1.96 Diluted $ 6.96 $ 10.39 $ 1.96 (1) For purposes of calculating net income per share under the if-converted method, the Company has excluded the impact of the MCPS dividends for the year ended December 31, 2023, as the assumed conversion of the MCPS into ordinary shares on a weighted average basis was more dilutive to net income per share than the impact of the MCPS dividends. The Company has included the impact of the MCPS dividends for the year ended December 31, 2022, as the impact was more dilutive to net income per share than the impact of assuming the conversion of the MCPS into ordinary shares on a weighted average basis. Share Repurchase Programs In July 2024, the Board of Directors authorized a share repurchase program of up to $5.0 billion of ordinary shares, which commenced in August 2024 following completion of the Company’s $2.0 billion January 2019 share repurchase program. This share repurchase program provides for share purchases in the open market or in privately negotiated transactions (which may include derivative transactions, including an accelerated share repurchase program (“ASR”)), depending on share price, market conditions and other factors, as determined by the Company. Accelerated Share Repurchase Agreement As part of the Company’s share repurchase program, on August 1, 2024, the Company entered into ASR agreements with each of Goldman Sachs International and JPMorgan Chase Bank, N.A. to repurchase an aggregate of $3.0 billion of Aptiv’s ordinary shares (the “ASR Agreements”). Under the terms of the ASR Agreements, on August 2, 2024, the Company made an aggregate payment of $3.0 billion (the “Repurchase Price”) and received initial deliveries of approximately 30.8 million ordinary shares with a value of $2.25 billion, which were retired immediately and recorded as a reduction to shareholders’ equity. Aptiv incurred approximately $4 million of direct costs in connection with the ASR Agreements. Given the Company’s ability to settle in shares, as described below, the remaining $750 million prepaid forward contract was classified as a reduction to additional paid-in capital as of December 31, 2024. In January 2025, a portion of the ASR Agreements were settled, and Aptiv received approximately 5.6 million ordinary shares, which were retired immediately. The Company initially funded the accelerated share repurchase program with cash on hand and borrowings under the Bridge Credit Agreement. The Bridge Credit Agreement was subsequently repaid and terminated during the third quarter of 2024 using proceeds from the Term Loan A and issuance of the 2024 Senior Notes and 2024 Junior Notes, as further described in Note 11. Debt. The total number of shares to be repurchased under each ASR Agreement will be based on the average daily volume-weighted average price of our ordinary shares on specified dates during the term of such ASR Agreement, less a discount and subject to adjustments pursuant to the terms and conditions of the ASR Agreements. Upon final settlement of the ASR Agreements, under certain circumstances, the relevant counterparty may be required to deliver additional ordinary shares, or we may be required to deliver ordinary shares or to make a cash payment to the relevant counterparty, at our election. The final settlements under the ASR Agreements are scheduled to occur no later than the second quarter of 2025, and in each case may be accelerated at the option of the applicable counterparty. A summary of the ordinary shares repurchased during the years ended December 31, 2024 and 2023 is as follows: Year Ended December 31, 2024 2023 Total number of shares repurchased 44,431,332 4,701,558 Average price paid per share $ 75.40 $ 84.59 Total (in millions) $ 3,350 $ 398 There were no shares repurchased during the year ended December 31, 2022. As of December 31, 2024, approximately $2,515 million of share repurchases remained available under the July 2024 share repurchase program. All previously repurchased shares were retired, and are reflected as a reduction of ordinary share capital for the par value of the shares, with the excess applied as reductions to additional paid-in-capital and retained earnings. Preferred Dividends During the year ended December 31, 2023, the Board of Directors declared and paid quarterly cash dividends of approximately $1.375 per MCPS for a total of $32 million during the year.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives And Hedging Activities	DERIVATIVES AND HEDGING ACTIVITIES Cash Flow Hedges Aptiv is exposed to market risk, such as fluctuations in foreign currency exchange rates, commodity prices and changes in interest rates, which may result in cash flow risks. To manage the volatility relating to these exposures, Aptiv aggregates the exposures on a consolidated basis to take advantage of natural offsets. For exposures that are not offset within its operations, Aptiv enters into various derivative transactions pursuant to its risk management policies, which prohibit holding or issuing derivative financial instruments for speculative purposes, and designation of derivative instruments is performed on a transaction basis to support hedge accounting. The changes in fair value of these hedging instruments are offset in part or in whole by corresponding changes in the fair value or cash flows of the underlying exposures being hedged. Aptiv assesses the initial and ongoing effectiveness of its hedging relationships in accordance with its documented policy. As of December 31, 2024, the Company had the following outstanding notional amounts related to commodity and foreign currency forward and option contracts designated as cash flow hedges that were entered into to hedge forecasted exposures: Commodity Quantity Hedged Unit of Measure Notional Amount (Approximate USD Equivalent) (in thousands) (in millions) Copper 101,754 pounds $ 410 Foreign Currency Quantity Hedged Unit of Measure Notional Amount (Approximate USD Equivalent) (in millions) Mexican Peso 35,127 MXN $ 1,700 Chinese Yuan Renminbi 2,737 RMB $ 375 Polish Zloty 915 PLN $ 225 Hungarian Forint 25,837 HUF $ 65 British Pound 21 GBP $ 25 As of December 31, 2024, Aptiv has entered into derivative instruments to hedge cash flows extending out to December 2026. Gains and losses on derivatives qualifying as cash flow hedges are recorded in accumulated OCI, to the extent that hedges are effective, until the underlying transactions are recognized in earnings. Unrealized amounts in accumulated OCI will fluctuate based on changes in the fair value of hedge derivative contracts at each reporting period. Net losses on cash flow hedges included in accumulated OCI as of December 31, 2024 were $123 million (approximately $100 million, net of tax). Of this total, approximately $ 73 million cost of sales 50 million Net Investment Hedges The Company is also exposed to the risk that adverse changes in foreign currency exchange rates could impact its net investment in non-U.S. subsidiaries. To manage this risk, the Company designates certain qualifying derivative and non-derivative instruments, including foreign currency forward contracts and foreign currency-denominated debt, as net investment hedges of certain non-U.S. subsidiaries. The gains or losses on instruments designated as net investment hedges are recognized within OCI to offset changes in the value of the net investment in these foreign currency-denominated operations. Gains and losses reported in accumulated OCI are reclassified to earnings only when the related currency translation adjustments are required to be reclassified, usually upon sale or liquidation of the investment. Cash flows from derivatives designated as net investment hedges are classified as investing activities within the consolidated statements of cash flows. The Company has entered into a series of forward contracts, each of which have been designated as net investment hedges of the foreign currency exposure of the Company’s investments in certain RMB-denominated subsidiaries. During the years ended December 31, 2024, 2023 and 2022, the Company paid $2 million, and received $6 million and $7 million, respectively, at settlement related to these series of forward contracts which matured throughout each respective year. In September 2024, the Company entered into forward contracts with a total notional amount of 700 million RMB (approximately $100 million, using foreign currency rates on the trade date), which mature in March 2025. Refer to the tables below for details of the fair value recorded in the consolidated balance sheets and the effects recorded in the consolidated statements of operations and consolidated statements of comprehensive income related to these derivative instruments. The Company has designated the €750 million 2024 Euro-denominated Senior Notes and the €500 million 2016 Euro-denominated Senior Notes as net investment hedges of the foreign currency exposure of its investments in certain Euro-denominated subsidiaries, and had designated the €700 million 2015 Euro-denominated Senior Notes prior to being redeemed in December 2024, as more fully described in Note 11. Debt. Due to changes in the value of the Euro-denominated debt instruments designated as net investment hedges, during the years ended December 31, 2024 and 2023, $77 million of gains and $39 million of losses, respectively, were recognized within the cumulative translation adjustment component of OCI. Included in accumulated OCI related to these net investment hedges were cumulative gains of $75 million as of December 31, 2024 and losses of $2 million as of December 31, 2023. Derivatives Not Designated as Hedges In certain occasions the Company enters into certain foreign currency and commodity contracts that are not designated as hedges. When hedge accounting is not applied to derivative contracts, gains and losses are recorded to other income (expense), net and cost of sales in the consolidated statements of operations. Fair Value of Derivative Instruments in the Balance Sheet The fair value of derivative financial instruments recorded in the consolidated balance sheets as of December 31, 2024 and 2023 are as follows: Asset Derivatives Liability Derivatives Net Amounts of Assets and (Liabilities) Presented in the Balance Sheet Balance Sheet Location December 31, Balance Sheet Location December 31, December 31, (in millions) Derivatives designated as cash flow hedges: Commodity derivatives Other current assets $ 5 Accrued liabilities $ 5 Foreign currency derivatives* Other current assets 10 Other current assets 3 $ 7 Foreign currency derivatives* Accrued liabilities 10 Accrued liabilities 80 (70) Commodity derivatives Other long-term assets 1 Other long-term liabilities 7 Foreign currency derivatives* Other long-term liabilities 3 Other long-term liabilities 35 (32) Derivatives designated as net investment hedges: Foreign currency derivatives Other current assets 5 Accrued liabilities — Total derivatives designated as hedges $ 34 $ 130 Derivatives not designated: Foreign currency derivatives* Other current assets $ 1 Other current assets $ — 1 Foreign currency derivatives* Accrued liabilities — Accrued liabilities 1 (1) Total derivatives not designated as hedges $ 1 $ 1 Asset Derivatives Liability Derivatives Net Amounts of Assets and (Liabilities) Presented in the Balance Sheet Balance Sheet Location December 31, 2023 Balance Sheet Location December 31, 2023 December 31, 2023 (in millions) Derivatives designated as cash flow hedges: Commodity derivatives Other current assets $ 1 Accrued liabilities $ 4 Foreign currency derivatives* Other current assets 133 Other current assets — $ 133 Commodity derivatives Other long-term assets 2 Other long-term liabilities 1 Foreign currency derivatives* Other long-term assets 22 Other long-term assets 1 21 Derivatives designated as net investment hedges: Foreign currency derivatives Other current assets — Accrued liabilities 2 Total derivatives designated as hedges $ 158 $ 8 Derivatives not designated: Foreign currency derivatives* Other current assets $ 4 Other current assets $ — 4 Total derivatives not designated as hedges $ 4 $ — * Derivative instruments within this category are subject to master netting arrangements and are presented on a net basis in the consolidated balance sheets in accordance with accounting guidance related to the offsetting of amounts related to certain contracts.

Fair Value Of Financial Instrum

Fair Value Of Financial Instruments	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Of Financial Instruments	FAIR VALUE OF FINANCIAL INSTRUMENTS Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value measurements are based on one or more of the following three valuation techniques: Market —This approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. Income —This approach uses valuation techniques to convert future amounts to a single present value amount based on current market expectations. Cost —This approach is based on the amount that would be required to replace the service capacity of an asset (replacement cost). Aptiv uses the following fair value hierarchy prescribed by U.S. GAAP, which prioritizes the inputs used to measure fair value as follows: Level 1 —Unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 —Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 —Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Typically, assets and liabilities are considered to be fair valued on a recurring basis if fair value is measured regularly. However, if the fair value measurement of an instrument does not necessarily result in a change in the amount recorded on the consolidated balance sheets, assets and liabilities are considered to be fair valued on a nonrecurring basis. This generally occurs when accounting guidance requires assets and liabilities to be recorded at the lower of cost or fair value, or assessed for impairment. Fair Value Measurements on a Recurring Basis Derivative instruments —All derivative instruments are required to be reported on the balance sheet at fair value unless the transactions qualify and are designated as normal purchases or sales. Changes in fair value are reported currently through earnings unless they meet hedge accounting criteria. Aptiv’s derivative exposures are with counterparties with long-term investment grade credit ratings. Aptiv estimates the fair value of its derivative contracts using an income approach based on valuation techniques to convert future amounts to a single, discounted amount. Estimates of the fair value of foreign currency and commodity derivative instruments are determined using exchange traded prices and rates. Aptiv also considers the risk of non-performance in the estimation of fair value, and includes an adjustment for non-performance risk in the measure of fair value of derivative instruments. The non-performance risk adjustment reflects the credit default spread (“CDS”) applied to the net commodity by counterparty and foreign currency exposures by counterparty. When Aptiv is in a net derivative asset position, the counterparty CDS rates are applied to the net derivative asset position. When Aptiv is in a net derivative liability position, estimates of peer companies’ CDS rates are applied to the net derivative liability position. In certain instances where market data is not available, Aptiv uses management judgment to develop assumptions that are used to determine fair value. This could include situations of market illiquidity for a particular currency or commodity or where observable market data may be limited. In those situations, Aptiv generally surveys investment banks and/or brokers and utilizes the surveyed prices and rates in estimating fair value. As of December 31, 2024 and 2023, Aptiv was in a net derivative liability position of $96 million and a net derivative asset position of $154 million, respectively, and no significant adjustments were recorded for nonperformance risk based on the application of peer companies’ CDS rates, evaluation of our own nonperformance risk and because Aptiv’s exposures were to counterparties with investment grade credit ratings. Refer to Note 17. Derivatives and Hedging Activities for further information regarding derivatives. Contingent consideration —The liability for contingent consideration is estimated as of the date of the acquisition and is recorded as part of the purchase price, and is subsequently re-measured to fair value at each reporting date, based on a probability-weighted analysis using a rate that reflects the uncertainty surrounding the expected outcomes, which the Company believes is appropriate and representative of market participant assumptions. The measurement of the liability for contingent consideration is based on significant inputs that are not observable in the market, and is therefore classified as a Level 3 measurement in accordance with ASC Topic 820-10-35. Examples of utilized unobservable inputs are estimated future earnings or milestone achievements of the acquired businesses and applicable discount rates. The estimate of the liability may fluctuate if there are changes in the forecast of acquired businesses’ future earnings or milestone achievements, as a result of actual earnings or milestone achievements or in the discount rates used to determine the present value of contingent future cash flows. The Company regularly reviews these assumptions and makes adjustments to the fair value measurements as required by facts and circumstances. There was no liability for contingent consideration as of December 31, 2024 and 2023. During the year ended December 31, 2023, the Company paid $10 million of contingent consideration based on the actual level of earnings of the acquired business during the contractual earn-out period, reducing the contingent consideration liability to zero as of December 31, 2023. This payment was recorded as a cash outflow from financing activities in the consolidated statements of cash flows in accordance with ASC Topic 230-10-45, as the full amount of the payment represented the acquisition date fair value of the contingent consideration liability. Publicly traded equity securities —All publicly traded equity securities are reported at fair value as of each reporting date. The measurement of the asset is based on quoted prices for identical assets on active market exchanges. Gains and losses from changes in the fair value of these securities are recorded within other income (expense), net on the consolidated statements of operations. Available-for-sale debt securities —Investments in available-for-sale debt securities are reported at fair value with changes in the fair value recorded in other comprehensive income. Changes in the fair value of available-for-sale debt securities impact earnings only when such securities are sold, or an allowance for expected credit losses or impairment is recognized. As further described in Note 5. Investments in Affiliates, the Company owns investments in Maxieye and StradVision, which are classified as available-for-sale debt securities due to the Company’s redemption rights. The balance of these investments totaled $161 million as of December 31, 2024 and is included within other long-term assets in the consolidated balance sheet. The fair value measurements of these investments are based on significant inputs that are not observable in the market, and are therefore classified as a Level 3 measurement. The below table summarizes the cost, cumulative unrealized gains, cumulative unrealized losses and estimated fair value of Aptiv’s debt securities as of December 31, 2024: Cost basis Gross unrealized gains Gross unrealized losses Estimated fair value (in millions) As of December 31, 2024 Available-for-sale debt securities $ 165 $ 8 $ (12) $ 161 Total debt securities $ 165 $ 8 $ (12) $ 161 The change in fair value of available-for-sale debt securities classified as a Level 3 measurement for the year ended December 31, 2024 is as follows: December 31, (in millions) Fair value at beginning of period $ — Additions 165 Measurement adjustments (4) Fair value at end of period $ 161 There were no impairment charges related to these investments during the year ended December 31, 2024. As of December 31, 2024 and 2023, Aptiv had the following assets measured at fair value on a recurring basis: Total Quoted Prices in Active Markets Significant Other Observable Inputs Significant Unobservable Inputs (in millions) As of December 31, 2024 Commodity derivatives $ 6 $ — $ 6 $ — Foreign currency derivatives 13 — 13 — Publicly traded equity securities 11 11 — — Available-for-sale debt securities 161 — — 161 Total $ 191 $ 11 $ 19 $ 161 As of December 31, 2023 Commodity derivatives $ 3 $ — $ 3 $ — Foreign currency derivatives 158 — 158 — Publicly traded equity securities 14 14 — — Total $ 175 $ 14 $ 161 $ — As of December 31, 2024 and 2023, Aptiv had the following liabilities measured at fair value on a recurring basis: Total Quoted Prices in Active Markets Significant Other Observable Inputs Significant Unobservable Inputs (in millions) As of December 31, 2024 Commodity derivatives $ 12 $ — $ 12 $ — Foreign currency derivatives 103 — 103 — Total $ 115 $ — $ 115 $ — As of December 31, 2023 Commodity derivatives $ 5 $ — $ 5 $ — Foreign currency derivatives 2 — 2 — Total $ 7 $ — $ 7 $ — Non-derivative financial instruments —Aptiv’s non-derivative financial instruments include cash and cash equivalents, accounts and notes receivable, accounts payable, as well as debt, which consists of its accounts receivable factoring arrangement, finance leases and other debt issued by Aptiv’s non-U.S. subsidiaries, the Revolving Credit Facility, the Term Loan A and all series of outstanding senior and junior notes. The fair value of debt is based on quoted market prices for instruments with public market data or significant other observable inputs for instruments without a quoted public market price (Level 2). As of December 31, 2024 and 2023, total debt was recorded at $8,352 million and $6,213 million, respectively, and had estimated fair values of $7,125 million and $5,255 million, respectively. For all other financial instruments recorded as of December 31, 2024 and 2023, fair value approximates book value. Fair Value Measurements on a Nonrecurring Basis In addition to items that are measured at fair value on a recurring basis, Aptiv also has items in its balance sheet that are measured at fair value on a nonrecurring basis. As these items are not measured at fair value on a recurring basis, they are not included in the tables above. Financial and nonfinancial assets and liabilities that are measured at fair value on a nonrecurring basis include long-lived assets, assets and liabilities held for sale, intangible assets, equity investments without readily determinable fair values and liabilities for exit or disposal activities measured at fair value upon initial recognition. During the year ended December 31, 2024, Aptiv recorded non-cash long-lived asset impairment charges of $14 million within cost of sales related to operating lease right-of-use assets that will no longer be in use during the remaining lease terms and $8 million within cost of sales related to the declines in the fair value of certain fixed assets in connection with planned site exits. In addition, Aptiv recorded a non-cash long-lived asset impairment charge of $36 million within net gain on equity method transactions related to its equity method investment in TTTech Auto, as further discussed in Note 5. Investments in Affiliates. During the year ended December 31, 2023, Aptiv recorded non-cash long-lived asset impairment charges of $11 million within cost of sales primarily related to an operating lease right-of-use asset in Ukraine that will no longer be in use during the remaining lease term, $7 million within cost of sales related to the abandonment of certain fixed assets and declines in the fair values of certain fixed assets, and additional non-cash asset impairment charges of $18 million within other income (expense), net related to its equity investments without readily determinable fair value. During the year ended December 31, 2022, Aptiv recorded non-cash long-lived asset impairment charges of $8 million and other charges of $3 million. These charges were primarily related to the conflict between Ukraine and Russia and were recorded within cost of sales. In addition, Aptiv determined that our former majority owned subsidiary in Russia met the held for sale criteria as of June 30, 2022. Consequently, during the year ended December 31, 2022, the Company recorded a charge of $51 million to reduce the carrying value of the subsidiary to fair value, which was recorded primarily within cost of sales. Fair value of long-lived and other assets is determined primarily using the anticipated cash flows discounted at a rate commensurate with the risk involved and a review of appraisals or other market indicators and management estimates. As such, Aptiv has determined that the fair value measurements of long-lived and other assets principally fall in Level 3 of the fair value hierarchy. The fair value of the Company’s investment in TTTech Auto was determined based on the contractual sales price pursuant to the executed purchase and sale agreement, as further discussed in Note 5. Investments in Affiliates. As such, Aptiv has determined that the fair value measurement of TTTech Auto falls in Level 2 of the fair value hierarchy.

Acquisition of Controlling Interest in Intercable Automotive Solutions S.r.l. On November 30, 2022, Aptiv acquired 85% of the equity interests of Intercable Automotive Solutions S.r.l. (“Intercable Automotive”), a manufacturer of high-voltage busbars and interconnect solutions, for total consideration of $609 million. Intercable Automotive was formerly a subsidiary of Intercable S.r.l. The results of operations of Intercable Automotive are reported within the Signal and Power Solutions segment from the date of acquisition. The Company acquired its interest in Intercable Automotive utilizing cash on hand. Upon completion of the acquisition, Aptiv incurred transaction related expenses totaling approximately $10 million, which were recorded within other income (expense), net in the consolidated statements of operations in the fourth quarter of 2022. The acquisition was accounted for as a business combination, with the total purchase price allocated on a preliminary basis using information available, in the fourth quarter of 2022. The purchase price was increased by a net working capital adjustment of approximately $3 million, which was paid to the seller and recorded in the second quarter of 2023, and was allocated to goodwill. Additional adjustments recorded from the amounts disclosed as of December 31, 2022 also included an increase to property, plant and equipment of $9 million and minor adjustments to various other assets acquired and liabilities assumed, which, together with the net working capital adjustment described above, resulted in a net reduction to goodwill of $7 million. The final purchase price and related allocation to the acquired net assets of Intercable Automotive based on their estimated fair values is shown below (in millions): Assets acquired and liabilities assumed Purchase price, cash consideration, net of cash acquired $ 609 Inventory $ 78 Property, plant and equipment 86 Intangible assets 286 Deferred tax liabilities (83) Other liabilities, net (13) Identifiable net assets acquired 354 Goodwill resulting from purchase 350 Total 704 Less: redeemable noncontrolling interest (95) Total purchase price allocation $ 609 Intangible assets include $202 million recognized for the fair value of customer-based assets with approximate useful lives of nineteen years, $63 million of technology-related assets with estimated useful lives of approximately fifteen years and $21 million recognized for the fair value of the trade name license with an approximate useful life of fifteen years. The estimated fair value of these assets was based on third-party valuations and management’s estimates, generally utilizing income and market approaches. Goodwill recognized in this transaction is primarily attributable to synergies expected to arise after the acquisition and the assembled workforce of Intercable Automotive and is not deductible for tax purposes. Concurrent with the acquisition, the Company entered into an agreement with the noncontrolling interest holders that provides the Company with the right to purchase, and the noncontrolling interest holders with the right to sell, the remaining 15% of Intercable Automotive for cash of up to €155 million, beginning in 2026. The final purchase price is contractually defined and will be determined based on Intercable Automotive’s 2025 operating results. Due to the noncontrolling interest holders’ redemption rights, the noncontrolling interest has been classified as redeemable noncontrolling interest in the temporary equity section of the consolidated balance sheet. The fair value of the noncontrolling interest was determined using a Monte Carlo simulation approach and includes several assumptions including estimated future profitability, expected volatility rate and risk free rate. The pro forma effects of this acquisition would not materially impact the Company’s reported results for any period presented, and as a result no pro forma financial statements were presented. Sale of Interest in Majority Owned Russian Subsidiary Given the sanctions put in place by the E.U., U.S. and other governments, which restrict our ability to conduct business in Russia, we initiated a plan in the second quarter of 2022 to exit our 51% owned subsidiary in Russia. As a result, the Company determined that this subsidiary, which was reported within the Signal and Power Solutions segment, initially met the held for sale criteria as of June 30, 2022. Consequently, during the year ended December 31, 2022, the Company recorded a pre-tax charge of $51 million to impair the carrying value of the Russian subsidiary’s net assets to fair value. On May 30, 2023, the Company completed the sale of its entire interest in the Russian subsidiary to JSC Samara Cables Company, the sole minority shareholder in the Russian subsidiary, for a nominal amount in exchange for all of the Company’s shares in the subsidiary. As a result of this transaction, the net assets held for sale of the Russian subsidiary were deconsolidated from the Company’s consolidated financial statements and the Company did not record any incremental gain or loss resulting from this disposition. Furthermore, losses relating to the Russian subsidiary during the held for sale period were de minimis. The former Russian subsidiary is not considered to be a related party of the Company after deconsolidation.

Share-Based Payment Arrangement [Abstract]
Share-based Compensation	SHARE-BASED COMPENSATION Long Term Incentive Plan The Aptiv PLC Long-Term Incentive Plan, as amended and restated effective April 23, 2015 (the “PLC LTIP”), allowed for the grant of awards of up to 25,665,448 ordinary shares for long-term compensation. The PLC LTIP was designed to align the interests of management and shareholders. The Company has awarded annual long-term grants of RSUs under the PLC LTIP in order to align management compensation with Aptiv’s overall business strategy. All of the RSUs granted under the PLC LTIP are eligible to receive dividend equivalents for any dividend paid from the grant date through the vesting date. When applicable, dividend equivalents are paid out in ordinary shares upon vesting of the underlying RSUs. In April 2024, the Company’s shareholders approved a new long-term incentive plan, the 2024 Long-Term Incentive Plan (the “2024 LTIP”). The 2024 LTIP allows for the grant of awards of up to 9,880,000 ordinary shares for long-term compensation. Similar to the PLC LTIP, the 2024 LTIP is designed to align the interests of management and shareholders. The awards can be in the form of shares, options, stock appreciation rights, restricted stock, RSUs, performance awards and other share-based awards to the employees, directors, consultants and advisors of the Company. Beginning in April 2024, all awards of equity compensation are made under the 2024 LTIP and no further awards will be made under the PLC LTIP. In addition, the Company has competitive and market-appropriate ownership requirements for its directors and officers. In connection with the reorganization transaction as further described in Note 1. General, in December 2024, Old Aptiv established a new publicly-listed Jersey parent company, New Aptiv, which is resident for tax purposes in Switzerland. As a result of the Transaction, all issued and outstanding ordinary shares of Old Aptiv were exchanged on a one-for-one basis for newly issued ordinary shares of New Aptiv. In connection with the Transaction, New Aptiv assumed Old Aptiv’s PLC LTIP and 2024 LTIP. Board of Director Awards Aptiv has granted RSUs to the Board of Directors as detailed in the table below: Grant Date RSUs granted Grant Date Fair Value (1) Vesting Date Shares Issued Upon Vesting Fair Value of Shares at Issuance Shares Withheld to Cover Withholding Taxes (dollars in millions) April 2024 30,497 $ 2 April 2025 N/A N/A N/A April 2023 20,584 $ 2 April 2024 18,272 $ 1 2,312 April 2022 23,387 $ 2 April 2023 20,457 $ 2 2,930 (1) Determined based on the closing price of the Company’s ordinary shares on the date of the grant. Executive Awards Aptiv has made annual grants of RSUs to its executives in February of each year beginning in 2012. These awards include a time-based vesting portion and a performance-based vesting portion, as well as continuity awards in certain years. The time-based RSUs, which make up 40% (25% prior to 2021) of the awards for Aptiv’s officers and 50% for Aptiv’s other executives, vest ratably over three years beginning on the first anniversary of the grant date. The performance-based RSUs, which make up 60% (75% prior to 2021) of the awards for Aptiv’s officers and 50% for Aptiv’s other executives, vest at the completion of a three-year performance period if certain targets are met. Each executive will receive between 0% and 200% of his or her target performance-based award based on the Company’s performance against established company-wide performance metrics, which are: Metric 2020 - 2024 Grants Average return on net assets (1) 33% Cumulative net income 33% Relative total shareholder return (2) 33% (1) Average return on net assets is measured by tax-affected operating income divided by average net working capital plus average net property, plant and equipment for each calendar year during the respective performance period. (2) Relative total shareholder return is measured by comparing the average closing price per share of the Company’s ordinary shares for the specified trading days in December of the performance period to the average closing price per share of the Company’s ordinary shares for the specified trading days in December of the year preceding the grant, including dividends, and assessed against a comparable measure of competitor and peer group companies. The details of the annual executive grants were as follows: Grant Date RSUs Granted Grant Date Fair Value Time-Based Award Vesting Dates Performance-Based Award Vesting Date (in millions) February 2020 0.75 $ 62 Annually on anniversary of grant date, 2021 - 2023 December 31, 2022 February 2021 0.44 $ 72 Annually on anniversary of grant date, 2022 - 2024 December 31, 2023 February 2022 0.59 $ 80 Annually on anniversary of grant date, 2023 - 2025 December 31, 2024 February 2023 0.79 $ 99 Annually on anniversary of grant date, 2024 - 2026 December 31, 2025 February 2024 1.12 $ 94 Annually on anniversary of grant date, 2025 - 2027 December 31, 2026 The grant date fair value of the RSUs is determined based on the target number of awards issued, the closing price of the Company’s ordinary shares on the date of the grant of the award, including an estimate for forfeitures, and a contemporaneous valuation performed by a third-party valuation specialist with respect to the relative total shareholder return awards. Any new executives hired after the annual executive RSU grant date may be eligible to participate in the 2024 LTIP. The Company has also granted additional awards to employees in certain periods under both the PLC LTIP and 2024 LTIP. Any off-cycle grants made to new hires or other employees are valued at their grant date fair value based on the closing price of the Company’s ordinary shares on the date of such grant. The details of shares issued for vested annual executive grants are as follows: Time-Based Awards Performance-Based Awards Vesting Date Ordinary Shares Issued Upon Vesting Fair Value of Shares at Issuance Ordinary Shares Withheld to Cover Withholding Taxes Ordinary Shares Issued Upon Vesting Fair Value of Shares at Issuance Ordinary Shares Withheld to Cover Withholding Taxes (dollars in millions) Q1 2024 461,052 $ 36 188,897 151,245 $ 12 65,910 Q1 2023 286,337 $ 33 116,753 315,664 $ 37 138,036 Q1 2022 354,600 $ 46 140,409 325,283 $ 42 136,143 A summary of RSU activity, including award grants, vesting and forfeitures is provided below: RSUs Weighted Average Grant Date Fair Value (in thousands) Nonvested, January 1, 2022 1,344 $ 131.40 Granted 939 $ 122.73 Vested (713) $ 109.36 Forfeited (323) $ 134.75 Nonvested, December 31, 2022 1,247 $ 136.61 Granted 1,545 $ 117.09 Vested (549) $ 135.17 Forfeited (247) $ 119.13 Nonvested, December 31, 2023 1,996 $ 124.06 Granted 1,972 $ 77.95 Vested (714) $ 123.39 Forfeited (484) $ 114.99 Nonvested, December 31, 2024 2,770 $ 92.98 As of December 31, 2024, there were approximately 138,000 Aptiv performance-based RSUs, with a weighted average grant date fair value of $139.99, that were vested but not yet distributed. Aptiv recognized share-based compensation expense of $112 million ($96 million, net of tax), $107 million ($90 million, net of tax) and $86 million ($85 million net of tax) based on the Company’s best estimate of ultimate performance against the respective targets during the years ended December 31, 2024, 2023 and 2022, respectively. Aptiv will continue to recognize compensation expense, based on the grant date fair value of the awards applied to the Company’s best estimate of ultimate performance against the respective targets, over the requisite vesting periods of the awards. Based on the grant date fair value of the awards and the Company’s best estimate of ultimate performance against the respective targets as of December 31, 2024, unrecognized compensation expense on a pre-tax basis of approximately $172 million is anticipated to be recognized over a weighted average period of approximately two years. For the years ended December 31, 2024, 2023 and 2022, respectively, approximately $23 million, $33 million and $36 million of cash was paid and reflected as a financing activity in the consolidated statements of cash flows related to the tax withholding for vested RSUs. Subsidiary Awards During 2023, certain employees of Wind River were granted stock options in Westerly, LLC (a subsidiary of the Company and parent company of Wind River) (the “Subsidiary Awards”). These Subsidiary Awards vest ratably over a three year period subject to continuing employment. Subsidiary Awards become exercisable upon vesting. Refer to Note 20. Acquisitions and Divestitures for further information on the Wind River acquisition. A summary of the status of the Company’s non-vested Subsidiary Awards is provided below: Subsidiary Award Stock Options Weighted Average Grant Date Fair Value (in thousands) Nonvested, January 1, 2023 — $ — Granted 8,102 $ 3.66 Vested (2,305) $ 3.69 Forfeited (731) $ 3.69 Nonvested, December 31, 2023 5,066 $ 3.65 Granted 1,780 $ 3.19 Vested (1,898) $ 3.65 Forfeited (1,535) $ 3.66 Nonvested, December 31, 2024 3,413 $ 3.41 The following summarizes the weighted average inputs used in the Black-Scholes model to value the Subsidiary Awards granted during the years ended December 31, 2024 and 2023: Year Ended December 31, 2024 2023 Expected volatility (1) 35.16 % 42.99 % Expected term 3.5 years 3.5 years Expected dividends $ — $ — Risk-free interest rate 4.05 % 4.41 % (1) Expected volatility was primarily based on the historical volatility of a group of comparable publicly traded entities as determined by the Company.

Segment Reporting

Segment Reporting [Abstract]
Segment Reporting	SEGMENT REPORTING Aptiv operates its core business along the following operating segments, which are grouped on the basis of similar product, market and operating factors: • Signal and Power Solutions, which includes complete electrical architecture and component products. • Advanced Safety and User Experience, which includes vehicle technology and services in advanced safety, user experience and smart vehicle compute and software, as well as cloud-native software platforms, autonomous driving technologies and DevOps tools. • Eliminations and Other, which includes i) the elimination of inter-segment transactions, and ii) certain other expenses and income of a non-operating or strategic nature. The accounting policies of the segments are the same as those described in Note 2. Significant Accounting Policies, except that the disaggregated financial results for the segments have been prepared using a management approach, which is consistent with the basis and manner in which management internally disaggregates financial information for which Aptiv’s chief operating decision maker (“CODM”), who is the Company’s chairman and chief executive officer, regularly reviews financial results to assess performance of, and make internal operating decisions about allocating resources to, the segments. Generally, Aptiv evaluates segment performance based on stand-alone segment net income before interest expense, other income (expense), net, income tax (expense) benefit, equity income (loss), net of tax, amortization, restructuring, other acquisition and portfolio project costs (which includes costs incurred to integrate acquired businesses and to plan and execute product portfolio transformation actions, including business and product acquisitions and divestitures), asset impairments and other related charges, compensation expense related to acquisitions and gains (losses) on business divestitures and other transactions (“Adjusted Operating Income”). Aptiv’s management, including the CODM, utilizes Adjusted Operating Income as the key performance measure of segment income or loss to evaluate segment performance, and for planning and forecasting purposes to allocate resources to the segments, as management believes this measure is most reflective of the operational profitability or loss of Aptiv’s operating segments. The CODM regularly evaluates budget-to-actual and period-over-period variances for this metric when making decisions about the allocation of operating and capital resources to each segment. The CODM also uses Adjusted Operating Income in evaluating the operating performance of each segment and as part of determining the compensation of the segment managers and certain other employees. Segment Adjusted Operating Income should not be considered a substitute for results prepared in accordance with U.S. GAAP and should not be considered an alternative to net income attributable to Aptiv, which is the most directly comparable financial measure to Adjusted Operating Income that is prepared in accordance with U.S. GAAP. Segment Adjusted Operating Income, as determined and measured by Aptiv, should also not be compared to similarly titled measures reported by other companies. Included below are sales, significant expenses and operating data for Aptiv’s segments for the years ended December 31, 2024, 2023 and 2022, as well as balance sheet data as of December 31, 2024 and 2023.

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer	REVENUE Refer to Note 2. Significant Accounting Policies for a complete description of the Company’s revenue recognition accounting policy. Nature of Goods and Services The principal activity from which the Company generates its revenue is the manufacturing of production parts for OEM customers. Aptiv recognizes revenue for production parts at a point in time, rather than over time, as the performance obligation is satisfied when customers obtain control of the product upon title transfer and not as the product is manufactured or developed. Although production parts are highly customized with no alternative use, Aptiv does not have an enforceable right to payment as customers have the right to cancel a product program without a notification period. The amount of revenue recognized is based on the purchase order price and adjusted for revenue allocated to variable consideration (i.e., estimated rebates and price discounts), as applicable. Customers typically pay for production parts based on customary business practices with payment terms averaging 60 days. The Company also generates revenue from the sale of software licenses, post delivery support and maintenance and professional software services, primarily from Wind River, which the Company acquired in December 2022. Refer to Note 20. Acquisitions and Divestitures for further information on this acquisition. The Company generally recognizes revenue for software licenses and professional software services at a point in time upon delivery or when the services are provided. Revenue from post delivery support and maintenance for software contracts is generally recognized over time on a ratable basis over the contract term. Under certain of these arrangements, timing may differ between revenue recognition and billing. Disaggregation of Revenue Revenue generated from Aptiv’s operating segments is disaggregated by primary geographic market and by core product line in the following tables for the years ended December 31, 2024, 2023 and 2022. Information concerning geographic market reflects the manufacturing location. Revenue by geographic market for the years ended December 31, 2024, 2023 and 2022 is as follows: For the Year Ended December 31, 2024: Signal and Power Solutions Advanced Safety and User Experience Eliminations and Other Total (in millions) Geographic Market North America $ 5,106 $ 2,050 $ (15) $ 7,141 Europe, Middle East and Africa 3,849 2,655 (15) 6,489 Asia Pacific 4,667 1,086 (31) 5,722 South America 361 — — 361 Total net sales $ 13,983 $ 5,791 $ (61) $ 19,713 For the Year Ended December 31, 2023: Signal and Power Solutions Advanced Safety and User Experience Eliminations and Other Total (in millions) Geographic Market North America $ 5,343 $ 1,860 $ (8) $ 7,195 Europe, Middle East and Africa 4,040 2,713 (15) 6,738 Asia Pacific 4,600 1,122 (25) 5,697 South America 421 — — 421 Total net sales $ 14,404 $ 5,695 $ (48) $ 20,051 For the Year Ended December 31, 2022: Signal and Power Solutions Advanced Safety and User Experience Eliminations and Other Total (in millions) Geographic Market North America $ 5,026 $ 1,435 $ (10) $ 6,451 Europe, Middle East and Africa 3,289 2,094 (11) 5,372 Asia Pacific 4,236 1,058 (20) 5,274 South America 392 — — 392 Total net sales $ 12,943 $ 4,587 $ (41) $ 17,489 Revenue by core product line for the years ended December 31, 2024, 2023 and 2022 is as follows: Year Ended December 31, 2024 2023 2022 (in millions) Electrical Distribution Systems $ 8,247 $ 8,719 $ 7,628 Engineered Components Group 6,401 6,440 5,997 Eliminations (665) (755) (682) Signal and Power Solutions 13,983 14,404 12,943 Active Safety 2,932 2,522 1,961 Smart Vehicle Compute and Software 506 506 70 User Experience and Other 2,412 2,723 2,557 Eliminations (59) (56) (1) Advanced Safety and User Experience 5,791 5,695 4,587 Eliminations (61) (48) (41) Total net sales $ 19,713 $ 20,051 $ 17,489 Contract Balances Contract liabilities solely consist of deferred revenue. As of December 31, 2024 and 2023, the balance of contract liabilities was $124 million (of which $111 million was recorded in other current liabilities and $13 million was recorded in other long-term liabilities) and $109 million (of which $93 million was recorded in other current liabilities and $16 million was recorded in other long-term liabilities), respectively. The increase in the contract liabilities balance was primarily driven by cash payments received or due in advance of the performance obligation being satisfied, partially offset by $95 million of revenues recognized during the year ended December 31, 2024 that were included in the contract liability balance as of December 31, 2023. Contract assets are primarily comprised of unbilled receivables, which consist of amounts related to the Company’s unconditional right to consideration for completed performance obligations that have not been invoiced. As of December 31, 2024 and 2023, the balance of contract assets was $130 million (of which $65 million was recorded in other current assets and $65 million was recorded in other long-term assets) and $122 million (of which $55 million was recorded in other current assets and $67 million was recorded in other long-term assets), respectively. Remaining Performance Obligations For production parts, customer contracts generally are represented by a combination of a current purchase order and a current production schedule issued by the customer. There are no contracts for production parts outstanding beyond one year. Aptiv does not enter into fixed long-term supply agreements. As permitted, Aptiv does not disclose information about remaining performance obligations that have original expected durations of one year or less for production parts. Customer contracts for sales of software and related services are generally represented by a sales contract or purchase order with contract durations typically ranging from one to three years. Remaining performance obligations include contract liabilities and unbilled amounts that will be recognized as revenue in future periods. Transaction price allocated to the remaining performance obligation is based on the standalone selling price. The value of the transaction price allocated to remaining performance obligations under software and related service contracts as of December 31, 2024 was approximately $194 million. The Company expects to recognize approximately 70% of remaining performance obligations as revenue in the next twelve months, and the remainder thereafter. Payments to Customers From time to time, Aptiv makes payments to customers in conjunction with ongoing business. These payments to customers are generally recognized as a reduction to revenue at the time of the commitment to make these payments. However, certain other payments to customers, or upfront fees, are capitalized as they are directly attributable to a contract, are incremental and management expects the fees to be recoverable. As of December 31, 2024 and 2023, Aptiv has recorded $53 million (of which $10 million was classified within other current assets and $43 million was classified within other long-term assets) and $61 million (of which $12 million was classified within other current assets and $49 million was classified within other long-term assets), respectively, related to these capitalized upfront fees. Capitalized upfront fees are amortized to revenue based on the transfer of goods and services to the customer for which the upfront fees relate, which typically range from three to five years. There have been no impairment losses in relation to the costs capitalized. The amount of amortization to net sales was $17 million, $27 million and $28 million for the years ended December 31, 2024, 2023 and 2022, respectively.

Leases [Abstract]
Leases	LEASES Lease Portfolio The Company has operating and finance leases for real estate, office equipment, automobiles, forklifts and certain other equipment. The Company's leases have remaining lease terms of one year to 25 years, some of which include options to extend the leases for up to ten years, and some of which include options to terminate the leases within one year. Certain of our lease agreements include rental payments which are adjusted periodically for inflation. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. When available, we use the rate implicit in the lease to discount lease payments to present value; however, most of our leases do not provide a readily determinable implicit rate. Therefore, we must estimate our incremental borrowing rate to discount the lease payments based on information available at lease commencement. The incremental borrowing rate is not a quoted rate and is primarily derived by applying a spread over U.S. Treasury rates with a similar duration to the Company’s lease payments. The spread utilized is based on the Company’s credit rating and the impact of full collateralization. Related Party Lease Agreement Aptiv subleases certain office space to Motional, our autonomous driving joint venture, which has a remaining lease term of approximately four years as of December 31, 2024. Total income under the agreement was $3 million, $4 million and $4 million during the years ended December 31, 2024, 2023 and 2022, respectively. The sublease income and Aptiv’s associated operating lease cost are recorded to cost of sales in the consolidated statements of operations. The Company believes the terms of the lease agreement have not significantly been affected by the fact the Company and the lessee are related parties. The components of lease expense were as follows: Year Ended December 31, 2024 2023 2022 (in millions) Lease cost: Finance lease cost: Amortization of right-of-use assets $ 4 $ 5 $ 4 Interest on lease liabilities 1 1 1 Total finance lease cost 5 6 5 Operating lease cost 150 142 122 Short-term lease cost 9 17 14 Variable lease cost 22 3 1 Sublease income (1) (3) (5) (5) Total lease cost $ 183 $ 163 $ 137 (1) Sublease income excludes rental income from owned properties of $9 million, $8 million and $8 million for the years ended December 31, 2024, 2023 and 2022, respectively, which is included in other income, net. For the year ended December 31, 2024, the Company recorded impairment charges of $14 million related to operating lease right-of-use assets that will no longer be in use during the remaining lease terms, which was recorded within cost of sales in the consolidated statements of operations. For the year ended December 31, 2023, the Company recorded an impairment charge of $10 million related to an operating lease right-of-use asset in Ukraine that will no longer be in use during the remaining lease term, which was recorded within cost of sales in the consolidated statements of operations. Supplemental cash flow and other information related to leases was as follows: Year Ended December 31, 2024 2023 2022 (in millions) Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows for finance leases $ 1 $ 1 $ 1 Operating cash flows for operating leases $ 143 $ 134 $ 116 Financing cash flows for finance leases $ 5 $ 5 $ 4 Right-of-use assets obtained in exchange for lease obligations: Operating leases $ 54 $ 94 $ 102 Finance leases $ 2 $ 1 $ 3 Supplemental balance sheet information related to leases was as follows: December 31, 2024 2023 (dollars in millions) Operating leases: Operating lease right-of-use assets $ 495 $ 540 Accrued liabilities $ 124 $ 121 Long-term operating lease liabilities 412 453 Total operating lease liabilities $ 536 $ 574 Finance leases: Property and equipment $ 25 $ 38 Less: accumulated depreciation (18) (24) Total property, net $ 7 $ 14 Short-term debt $ 4 $ 5 Long-term debt 5 9 Total finance lease liabilities $ 9 $ 14 Weighted average remaining lease term: Operating leases 6 years 6 years Finance leases 3 years 3 years Weighted average discount rate: Operating leases 4.50 % 4.00 % Finance leases 4.50 % 4.75 % Maturities of lease liabilities were as follows: Operating Finance (in millions) As of December 31, 2024 2025 $ 144 $ 4 2026 125 2 2027 102 2 2028 74 1 2029 44 — Thereafter 116 — Total lease payments 605 9 Less: imputed interest (69) — Total $ 536 $ 9 As of December 31, 2024, the Company has entered into additional operating leases, primarily for real estate, that have not yet commenced of approximately $70 million.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Consolidation, Policy	Consolidation —The consolidated financial statements include the accounts of Aptiv and the subsidiaries in which Aptiv holds a controlling financial or management interest and variable interest entities of which Aptiv has determined that it is the primary beneficiary. Aptiv’s share of the earnings or losses of non-controlled affiliates, over which Aptiv exercises significant influence (generally a 20% to 50% ownership interest), is included in the consolidated operating results using the equity method of accounting. When Aptiv does not have the ability to exercise significant influence (generally when ownership interest is less than 20%), investments in non-consolidated affiliates without readily determinable fair value are measured at cost, less impairments, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer, while investments in publicly traded equity securities are measured at fair value based on quoted prices for identical assets on active market exchanges as of each reporting date. The Company monitors its investments in affiliates for indicators of other-than-temporary declines in value on an ongoing basis. If the Company determines that such a decline has occurred, an impairment loss 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 based on discounted cash flows or negotiated transaction values. Intercompany transactions and balances between consolidated Aptiv businesses have been eliminated. During the years ended December 31, 2024, 2023 and 2022, Aptiv received dividends of $12 million, $5 million and $5 million, respectively, from its equity method investments. The dividends were recognized as a reduction to the investment and represented a return on investment included in cash flows from operating activities. Aptiv’s investments in publicly traded equity securities totaled $11 million and $14 million as of December 31, 2024 and 2023, respectively, and are classified within other long-term assets in the consolidated balance sheets. Aptiv's non-publicly traded investments totaled $167 million and $51 million as of December 31, 2024 and 2023, respectively, and are classified within other long-term assets in the consolidated balance sheets. Refer to Note 5. Investments in Affiliates for further information regarding Aptiv’s investments. In 2022, the Company acquired 85% of the equity interests of Intercable Automotive Solutions S.r.l. (“Intercable Automotive”). Concurrent with the acquisition, the Company entered into an agreement with the noncontrolling interest holders that provides the Company with the right to purchase, and the noncontrolling interest holders with the right to sell, the remaining 15% of Intercable Automotive for cash at a contractually defined value beginning in 2026. As a result of this redemption feature, the Company recorded the redeemable noncontrolling interest at its acquisition-date fair value to temporary equity in the consolidated balance sheet. The redeemable noncontrolling interest is adjusted each reporting period for the income (loss) attributable to the noncontrolling interest, and for any measurement period adjustments necessary to record the redeemable noncontrolling interest at the higher of its redemption value, assuming it was redeemable at the reporting date, or its carrying value. Any measurement period adjustments are recorded to retained earnings, with a corresponding increase or reduction to net income attributable to Aptiv. Redeemable noncontrolling interest was $92 million and $99 million as of December 31, 2024 and 2023, respectively. Refer to Note 20. Acquisitions and Divestitures for further information regarding this acquisition and the redeemable noncontrolling interest.
Use of Estimates, Policy	Use of estimates —Preparation of consolidated financial statements in conformity with U.S. GAAP requires the use of estimates and assumptions that affect amounts reported therein. Generally, matters subject to estimation and judgment include amounts related to accounts receivable realization, inventory obsolescence, asset impairments, useful lives of intangible and fixed assets, deferred tax asset valuation allowances, income taxes, pension benefit plan assumptions, accruals related to litigation, warranty costs, environmental remediation costs, contingent consideration arrangements, redeemable noncontrolling interest, worker’s compensation accruals and healthcare accruals. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be based upon amounts that differ from those estimates.
Revenue Recognition, Policy	Revenue recognition —Revenue is measured based on consideration specified in a contract with a customer. Customer contracts for production parts generally are represented by a combination of a current purchase order and a current production schedule issued by the customer. Substantially all of the Company's revenue is generated from the sale of manufactured production parts, wherein there is a single performance obligation. Transfer of control and revenue recognition for the Company’s sales of production parts generally occurs upon shipment or delivery of the product, which is when title, ownership, and risk of loss pass to the customer and is based on the applicable customer shipping terms. Revenue is measured based on the transaction price and the quantity of parts specified in a contract with a customer. Refer to Note 24. Revenue for further detail of the Company’s accounting for its revenue from sales of production parts. Customer contracts for software licenses are generally represented by a sales contract or purchase order with contract durations typically ranging from one to three years. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. Revenue from software licenses and professional software services is generally recognized at a point in time upon delivery or when the services are provided. Revenue from post delivery support and maintenance for software contracts is generally recognized over time on a ratable basis over the contract term. Certain software license contracts contain multiple performance obligations, for which the Company allocates the contract’s transaction price to each performance obligation based on the estimated relative standalone selling price of each distinct performance obligation in the contract. The standalone selling prices are generally determined based on observable inputs, such as the prices of standalone sales and historical contract pricing. Under certain of these arrangements, timing may differ between revenue recognition and billing. Refer to Note 24. Revenue for further detail of the Company’s accounting for its revenue from contracts with customers, including contract balances associated with software sales. From time to time, Aptiv enters into pricing agreements with its customers that provide for price reductions on production parts, some of which are conditional upon achieving certain joint cost saving targets, which are accounted for as variable consideration. In these instances, revenue is recognized based on the agreed-upon price at the time of shipment if available, or in the event the Company concludes that a portion of the revenue for a given part may vary from the purchase order and requires estimation, the Company records consideration at the most likely amount that the Company expects to be entitled to based on historical experience and input from customer negotiations. Sales incentives and allowances are recognized as a reduction to revenue at the time of the related sale. In addition, from time to time, Aptiv makes payments to customers in conjunction with ongoing business. These payments to customers are generally recognized as a reduction to revenue at the time of the commitment to make these payments. However, certain other payments to customers, or upfront fees, meet the criteria to be considered a cost to obtain a contract as they are directly attributable to a contract, are incremental and management expects the fees to be recoverable. Aptiv collects and remits taxes assessed by different governmental authorities that are both imposed on and concurrent with a revenue-producing transaction between the Company and the Company’s customers. These taxes may include, but are not limited to, sales, use, value-added, and some excise taxes. Aptiv reports the collection of these taxes on a net basis (excluded from revenues). Shipping and handling fees billed to customers are included in net sales, while costs of shipping and handling are included in cost of sales. Refer to Note 24. Revenue for further information. Refer to Note 2. Significant Accounting Policies for a complete description of the Company’s revenue recognition accounting policy. Nature of Goods and Services The principal activity from which the Company generates its revenue is the manufacturing of production parts for OEM customers. Aptiv recognizes revenue for production parts at a point in time, rather than over time, as the performance obligation is satisfied when customers obtain control of the product upon title transfer and not as the product is manufactured or developed. Although production parts are highly customized with no alternative use, Aptiv does not have an enforceable right to payment as customers have the right to cancel a product program without a notification period. The amount of revenue recognized is based on the purchase order price and adjusted for revenue allocated to variable consideration (i.e., estimated rebates and price discounts), as applicable. Customers typically pay for production parts based on customary business practices with payment terms averaging 60 days. The Company also generates revenue from the sale of software licenses, post delivery support and maintenance and professional software services, primarily from Wind River, which the Company acquired in December 2022. Refer to Note 20. Acquisitions and Divestitures for further information on this acquisition. The Company generally recognizes revenue for software licenses and professional software services at a point in time upon delivery or when the services are provided. Revenue from post delivery support and maintenance for software contracts is generally recognized over time on a ratable basis over the contract term. Under certain of these arrangements, timing may differ between revenue recognition and billing.
Net Income Per Share, Policy	Net income per share —Basic net income per share is computed by dividing net income attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period. Diluted net income per share reflects the weighted average dilutive impact of all potentially dilutive securities from the date of issuance and is computed using the treasury stock and if-converted methods. Prior to the conversion of the 5.50% Mandatory Convertible Preferred Shares, Series A, $0.01 par value per share (the “MCPS”) into ordinary shares in June 2023, the if-converted method was used to determine if the impact of the conversion of the MCPS into ordinary shares was more dilutive than the MCPS dividends to net income per share. If so, the MCPS were assumed to have been converted at the later of the beginning of the period or the time of issuance, and the resulting ordinary shares were included in the denominator and the MCPS dividends were added back to the numerator. Unless otherwise noted, share and per share amounts included in these notes are on a diluted basis. Refer to Note 15. Shareholders’ Equity and Net Income Per Share for additional information including the calculation of basic and diluted net income per share. Net Income Per Share Basic net income per share is computed by dividing net income attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period. Diluted net income per share reflects the weighted average dilutive impact of all potentially dilutive securities from the date of issuance and is computed using the treasury stock and if-converted methods. Prior to the conversion of the MCPS into ordinary shares in June 2023, the if-converted method was used to determine if the impact of the conversion of the MCPS into ordinary shares was more dilutive than the MCPS dividends to net income per share. If so, the MCPS were assumed to have been converted at the later of the beginning of the period or the time of issuance, and the resulting ordinary shares were included in the denominator and the MCPS dividends were added back to the numerator. Unless otherwise noted, share and per share amounts included in these notes are on a diluted basis. For the year ended December 31, 2023, the calculation of net income per share includes the dilutive impacts of the MCPS under the if-converted method. For the year ended December 31, 2022, the impact of the MCPS calculated under the if-converted method was anti-dilutive, and as such 12.37 million ordinary shares underlying the MCPS were excluded from the diluted net income per share calculation. For all periods presented, the calculation of net income per share also contemplates the dilutive impacts, if any, of the Company’s share-based compensation plans. Refer to Note 21. Share-Based Compensation for additional information.
Research and Development, Policy	Research and development —Costs are incurred in connection with research and development programs that are expected to contribute to future earnings. Such costs are charged against income as incurred. Total research and development expenses, including engineering, net of customer reimbursements, were approximately $1,097 million, $1,289 million and $1,120 million for the years ended December 31, 2024, 2023 and 2022, respectively.
Cash and Cash Equivalents, Policy	Cash and cash equivalents —Cash and cash equivalents are defined as short-term, highly liquid investments with original maturities of three months or less, for which the book value approximates fair value.
Restricted Cash, Policy	Restricted cash —Restricted cash primarily includes balances on deposit at financial institutions that have issued letters of credit in favor of Aptiv and cash deposited into escrow accounts.
Investment, Policy	Short-term investments —Short-term investments are comprised of term deposits with original maturities greater than three months, for which book value approximates fair value. As described further in Note 11. Debt, these short-term investments were utilized to redeem the €700 million in aggregate principal amount of 1.50% Euro-denominated senior unsecured notes due 2025 (the “2015 Euro-denominated Senior Notes”) in December 2024.
Accounts Receivable, Policy	Accounts receivable —Aptiv enters into agreements to sell certain of its accounts receivable, primarily in Europe. Sales of receivables are accounted for in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 860, Transfers and Servicing (“ASC 860”). Agreements which result in true sales of the transferred receivables, as defined in ASC 860, which occur when receivables are transferred 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. Agreements that allow Aptiv to maintain effective control over the transferred receivables and which do not qualify as a sale, as defined in ASC 860, are accounted for as secured borrowings and recorded in the consolidated balance sheets within accounts receivable, net and short-term debt. The expenses associated with receivables factoring are recorded in the consolidated statements of operations within interest expense. The Company exchanges certain amounts of accounts receivable, primarily in the Asia Pacific region, for bank notes with original maturities greater than three months. The collection of such bank notes are included in operating cash flows based on the substance of the underlying transactions, which are operating in nature. Bank notes held by the Company with original maturities of three months or less are classified as cash and cash equivalents within the consolidated balance sheets, and those with original maturities of greater than three months are classified as notes receivable within other current assets. The Company may hold such bank notes until maturity, exchange them with suppliers to settle liabilities, or sell them to third-party financial institutions in exchange for cash.
Credit Loss, Policy	Credit losses —Aptiv is exposed to credit losses primarily through the sale of vehicle components, software licenses and services. Aptiv assesses the creditworthiness of a counterparty by conducting ongoing credit reviews, which considers the Company’s expected billing exposure and timing for payment, as well as the counterparty’s established credit rating. When a credit rating is not available, the Company’s assessment is based on an analysis of the counterparty’s financial statements. Aptiv also considers contract terms and conditions, country and political risk, and business strategy in its evaluation. Based on the outcome of this review, the Company establishes a credit limit for each counterparty. The Company continues to monitor its ongoing credit exposure through active review of counterparty balances against contract terms and due dates, which includes timely account reconciliation, payment confirmation and dispute resolution. The Company may also employ collection agencies and legal counsel to pursue recovery of defaulted receivables, if necessary. Aptiv primarily utilizes historical loss and recovery data, combined with information on current economic conditions and reasonable and supportable forecasts to develop the estimate of the allowance for doubtful accounts in accordance with ASC Topic 326, Financial Instruments – Credit Losses (“ASC 326”). As of December 31, 2024 and December 31, 2023, the Company reported $3,261 million and $3,546 million, respectively, of accounts receivable, net of the allowances, which includes the allowance for doubtful accounts of $37 million and $52 million, respectively. The provision for doubtful accounts was $11 million, $12 million, and $27 million for the years ended December 31, 2024, 2023 and 2022, respectively. Other changes in the allowance were not material for the year ended December 31, 2024.
Inventories, Policy	Inventories —As of December 31, 2024 and 2023, inventories are stated at the lower of cost, determined on a first-in, first-out basis, or net realizable value, including direct material costs and direct and indirect manufacturing costs. Refer to Note 3. Inventories for additional information. Obsolete inventory is identified based on analysis of inventory for known obsolescence issues, and, generally, the net realizable value of inventory on hand in excess of one year’s supply is fully-reserved. From time to time, payments may be received from suppliers. These payments from suppliers are recognized as a reduction of the cost of the material acquired during the period to which the payments relate. In some instances, supplier rebates are received in conjunction with or concurrent with the negotiation of future purchase agreements and these amounts are amortized over the prospective agreement period as purchases are made.
Property, Policy	Property —Major improvements that materially extend the useful life of property are capitalized. Expenditures for repairs and maintenance are charged to expense as incurred. Depreciation is determined based on a straight-line method over the estimated useful lives of groups of property. Leasehold improvements under finance leases are depreciated over the period of the lease or the life of the property, whichever is shorter. Refer to Note 6. Property, Net and Note 25. Leases for additional information.
Pre-production costs related to long-term supply agreements, Policy	Pre-production costs related to long-term supply agreements —The Company incurs pre-production engineering, development and tooling costs related to products produced for its customers under long-term supply agreements. Engineering, testing and other costs incurred in the design and development of production parts are expensed as incurred, unless the costs are reimbursable, as specified in a customer contract. As of December 31, 2024 and 2023, $305 million and $285 million of such contractually reimbursable costs were capitalized, respectively. These amounts are recorded within other current and other long-term assets in the consolidated balance sheets, as further detailed in Note 4. Assets. Special tools represent Aptiv-owned tools, dies, jigs and other items used in the manufacture of customer components that will be sold under long-term supply arrangements, the costs of which are capitalized within property, plant and equipment if the Company has title to the assets. Special tools also include capitalized unreimbursed pre-production tooling costs related to customer-owned tools for which the customer has provided Aptiv a non-cancellable right to use the tool. Aptiv-owned special tool balances are depreciated over the expected life of the special tool or the life of the related vehicle program, whichever is shorter. The unreimbursed costs incurred related to customer-owned special tools that are not subject to reimbursement are capitalized and depreciated over the expected life of the special tool or the life of the related vehicle program, whichever is shorter. At December 31, 2024 and 2023, the special tools balance, net of accumulated depreciation, was $489 million and $474 million, respectively, included within property, net in the consolidated balance sheets. As of December 31, 2024 and 2023, the Aptiv-owned special tools balance was $361 million and $373 million, respectively, and the customer-owned special tools balance was $128 million and $101 million, respectively.
Valuation of Long-Lived Assets, Policy	Valuation of long-lived assets —The carrying value of long-lived assets held for use, including definite-lived intangible assets, is periodically evaluated when events or circumstances warrant such a review. The carrying value of a long-lived asset held for use is considered impaired when the anticipated separately identifiable undiscounted cash flows from the asset are less than the carrying value of the asset. In that event, a loss is recognized based on the amount by which the carrying value exceeds the estimated fair value of the long-lived asset. Impairment losses on long-lived assets held for sale are recognized if the carrying value of the asset is in excess of the asset’s estimated fair value, reduced for the cost to dispose of the asset. Fair value of long-lived assets is determined primarily using the anticipated cash flows discounted at a rate commensurate with the risk involved (an income approach), and in certain situations Aptiv’s review of appraisals (a market approach). Refer to Note 6. Property, Net and Note 7. Intangible Assets and Goodwill for additional information.
Leases, Policy	Leases —The Company accounts for leases in accordance with FASB ASC Topic 842, Leases . The Company determines whether an arrangement is a lease at inception. For leases where the Company is the lessee, a lease liability and a right-of-use asset is recognized for all leases, with the exception of short-term leases with terms of twelve months or less. The lease liability represents the lessee’s obligation to make lease payments arising from a lease, and is measured as the present value of the lease payments. As the rate implicit in the lease is usually not known at lease commencement, the Company uses its incremental borrowing rate to discount the lease obligation. The right-of-use asset represents the lessee’s right to use a specified asset for the lease term, and is measured at the lease liability amount, adjusted for lease prepayment, lease incentives received and the Company’s initial direct costs. The Company applies the short-term lease exception, which results in a single lease cost being allocated over the lease term, generally on a straight-line basis, for leases with a term of twelve months or less. These leases are not presented in the consolidated balance sheets. Additionally, the Company applies the practical expedient to not separate lease components from non-lease components and instead accounts for both as a single lease component for all asset classes. Refer to Note 25. Leases for additional information.
Assets and Liabilities Held for Sale, Policy	Assets and liabilities held for sale —The Company considers assets to be held for sale when management, having the appropriate authority, approves and commits to a formal plan to actively market the assets for sale at a price reasonable in relation to their estimated fair value, the assets are available for immediate sale in their present condition, an active program to locate a buyer and other actions required to complete the sale have been initiated, the sale of the assets is probable and expected to be completed within one year and it is unlikely that significant changes will be made to the plan. Upon designation as held for sale, the Company records the assets at the lower of their carrying value or their estimated fair value, less cost to sell, and ceases to record depreciation expense on the assets. Assets and liabilities of a discontinued operation are reclassified as held for sale for all comparative periods presented in the consolidated balance sheets. For assets that meet the held for sale criteria but do not meet the definition of a discontinued operation, the Company reclassifies the assets and liabilities in the period in which the held for sale criteria are met, but does not reclassify prior period amounts.
Intangible Assets, Policy	Intangible assets —The Company amortizes definite-lived intangible assets over their estimated useful lives. The Company has definite-lived intangible assets related to patents and developed technology, customer relationships and trade names. Indefinite-lived in-process research and development intangible assets are not amortized, but are tested for impairment annually, or more frequently when indicators of potential impairment exist, until the completion or abandonment of the associated research and development efforts. Upon completion of the projects, the assets will be amortized over the expected economic life of the asset, which will be determined on that date. Should the project be determined to be abandoned, and if the asset developed has no alternative use, the full value of the asset will be charged to expense. 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. These indefinite-lived trade name assets are tested for impairment annually, or more frequently when indicators of potential impairment exist. Costs to renew or extend the term of acquired intangible assets are recognized as expense as incurred. No intangible asset impairment charges were recorded during the years ended December 31, 2024, 2023 and 2022. Refer to Note 7. Intangible Assets and Goodwill for additional information.
Goodwill, Policy	Goodwill —Goodwill is the excess of the purchase price over the estimated fair value of identifiable net assets acquired in business combinations. The Company tests goodwill for impairment annually in the fourth quarter, or more frequently when indications of potential impairment exist. The Company monitors the existence of potential impairment indicators throughout the fiscal year. The Company tests for goodwill impairment at the reporting unit level. Our reporting units are the components of operating segments which constitute businesses for which discrete financial information is available and is regularly reviewed by segment management. The impairment test involves first qualitatively assessing goodwill for impairment. If the qualitative assessment is not met the Company then performs a quantitative assessment by comparing the estimated fair value of each reporting unit to its carrying value, including goodwill. Fair value reflects the price a market participant would be willing to pay in a potential sale of the reporting unit. If the estimated fair value exceeds carrying value, then we conclude that no goodwill impairment has occurred. If the carrying value of the reporting unit exceeds its estimated fair value, the Company recognizes an impairment loss in an amount equal to the excess, not to exceed the amount of goodwill allocated to the reporting unit. When a quantitative assessment is required, the estimated fair value of the Company’s reporting units is primarily determined using discounted cash flow projections. Significant assumptions include management’s forecasted cash flows, including estimated future revenue growth, and the discount rate. Forecasts of future cash flows are based on management’s best estimates. The discount rate is determined using a weighted average cost of capital adjusted for risk factors specific to the reporting unit. The fair value of the reporting unit’s goodwill is sensitive to differences between estimated and actual cash flows, including changes in the projected revenue and discount rate. Refer to Note 20. Acquisitions and Divestitures, for further information on the goodwill attributable to the Company’s acquisitions. Goodwill impairment —The Company performs an annual goodwill impairment assessment in the fourth quarter. In 2024, the Company completed a qualitative goodwill impairment assessment and, after evaluating the results, events and circumstances of the Company, we concluded that sufficient evidence existed to assert qualitatively that it was more likely than not that the estimated fair value of all but one of our reporting units remained in excess of their carrying values. The Company performed a quantitative goodwill impairment test for its Wind River reporting unit within the Advanced Safety and User Experience segment, which has goodwill of $2,279 million, and determined its fair value to be in excess of its carrying value by less than 1%. No goodwill impairments were recorded in 2024, 2023 or 2022. Refer to Note 7. Intangible Assets and Goodwill for additional information.
Warranty and Product Recalls, Policy	Warranty and product recalls —Expected warranty costs for products sold are recognized at the time of sale of the product based on an estimate of the amount that eventually will be required to settle such obligations. These accruals are based on factors such as past experience, production changes, industry developments and various other considerations. 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 our warranty accrual at the time an obligation becomes probable and can be reasonably estimated. These estimates are adjusted from time to time based on facts and circumstances that impact the status of existing claims. Refer to Note 9. Warranty Obligations for additional information.
Income Taxes, Policy	Income taxes —Deferred tax assets and liabilities reflect temporary differences between the amount of assets and liabilities for financial and tax reporting purposes. Such amounts are adjusted, as appropriate, to reflect changes in tax rates expected to be in effect when the temporary differences reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period that includes the enactment date. A valuation allowance is recorded to reduce deferred tax assets to the amount that is more likely than not to be realized. In the event the Company determines it is more likely than not that the deferred tax assets will not be realized in the future, the valuation allowance adjustment to the deferred tax assets will be charged to earnings in the period in which the Company makes such a determination. In determining whether an uncertain tax position exists, the Company determines, based solely on its technical merits, whether the tax position is more likely than not to be sustained upon examination, and if so, a tax benefit is measured on a cumulative probability basis that is more likely than not to be realized upon the ultimate settlement. In determining the provision for income taxes for financial statement purposes, the Company makes certain estimates and judgments which affect its evaluation of the carrying value of its deferred tax assets, as well as its calculation of certain tax liabilities. As it relates to changes in accumulated other comprehensive income (loss), the Company’s policy is to release tax effects from accumulated other comprehensive income (loss) when the underlying components affect earnings. Refer to Note 14. Income Taxes for additional information.
Foreign Currency Translation, Policy	Foreign currency translation —Assets and liabilities of non-U.S. subsidiaries that use a currency other than U.S. dollars as their functional currency are translated to U.S. dollars at end-of-period currency exchange rates. The consolidated statements of operations of non-U.S. subsidiaries are translated to U.S. dollars at average-period currency exchange rates. The effect of translation for non-U.S. subsidiaries is generally reported in other comprehensive income (“OCI”). The accumulated foreign currency translation adjustment related to an investment in a foreign subsidiary is reclassified to net income upon sale or upon complete or substantially complete liquidation of the respective entity. The effect of remeasurement of assets and liabilities of non-U.S. subsidiaries that use the U.S. dollar as their functional currency is primarily included in cost of sales. Also included in cost of sales are gains and losses arising from transactions denominated in a currency other than the functional currency of a particular entity. Net foreign currency transaction losses of $1 million, $23 million and $30 million were included in the consolidated statements of operations for the year ended December 31, 2024, 2023 and 2022, respectively.
Restructuring, Policy	Restructuring —Aptiv continually evaluates alternatives to align the business with the changing needs of its customers and to lower operating costs. This includes the realignment of its existing manufacturing capacity, facility closures, or similar actions, either in the normal course of business or pursuant to significant restructuring programs. These actions may result in employees receiving voluntary or involuntary employee termination benefits, which are mainly pursuant to union or other contractual agreements or statutory requirements. Voluntary termination benefits are accrued when an employee accepts the related offer. Involuntary termination benefits are accrued upon the commitment to a termination plan and when the benefit arrangement is communicated to affected employees, or when liabilities are determined to be probable and estimable, depending on the existence of a substantive plan for severance or termination. Contract termination costs and certain early termination lease costs are recorded when contracts are terminated. All other exit costs are expensed as incurred. Refer to Note 10. Restructuring for additional information.
Customer Concentations, Policy	Customer concentrations —We sell our products and services to the major global OEMs in every region of the world. Our ten largest customers accounted for approximately 55%, 54% and 55% of our total net sales for the years ended December 31, 2024, 2023 and 2022, respectively, none of which individually exceeded 10% for any period presented. During the year ended December 31, 2024, our Signal and Power Solutions segment and our Advanced Safety and User Experience segment recognized net sales to each of our ten largest customers. During the years ended December 31, 2023 and December 31, 2022, our Signal and Power Solutions segment recognized net sales to each of our ten largest customers and our Advanced Safety and User Experience segment recognized net sales to eight of our ten largest customers.
Derivative Financial Instruments, Policy	Derivative financial instruments —All derivative instruments are required to be reported on the balance sheet at fair value unless the transactions qualify and are designated as normal purchases or sales. Changes in fair value are reported currently through earnings unless they meet hedge accounting criteria. Exposure to fluctuations in currency exchange rates and certain commodity prices are managed by entering into a variety of forward and option contracts and swaps with various counterparties. Such financial exposures are managed in accordance with the policies and procedures of Aptiv. Aptiv does not enter into derivative transactions for speculative or trading purposes. As part of the hedging program approval process, Aptiv identifies the specific financial risk which the derivative transaction will minimize, the appropriate hedging instrument to be used to reduce the risk and the correlation between the financial risk and the hedging instrument. Purchase orders, sales contracts, letters of intent, capital planning forecasts and historical data are used as the basis for determining the anticipated values of the transactions to be hedged. Aptiv does not enter into derivative transactions that do not have a high correlation with the underlying financial risk. Hedge positions, as well as the correlation between the transaction risks and the hedging instruments, are reviewed on an ongoing basis. Foreign exchange forward contracts are accounted for as hedges of firm or forecasted foreign currency commitments or foreign currency exposure of the net investment in certain foreign operations to the extent they are designated and assessed as highly effective. All foreign exchange contracts are marked to market on a current basis. Commodity swaps are accounted for as hedges of firm or anticipated commodity purchase contracts to the extent they are designated and assessed as effective. All other commodity derivative contracts that are not designated as hedges are either marked to market on a current basis or are exempted from mark to market accounting as normal purchases. At December 31, 2024 and 2023, the Company’s exposure to movements in interest rates was not hedged with derivative instruments. Refer to Note 17. Derivatives and Hedging Activities and Note 18. Fair Value of Financial Instruments for additional information.
Extended Disability Benefits, Policy	Extended disability benefits —Costs associated with extended disability benefits provided to inactive employees are accrued throughout the duration of their active employment. Workforce demographic data and historical experience are utilized to develop projections of time frames and related expense for post-employment benefits.
Workers' Compensation Benefits, Policy	Workers’ compensation benefits —Workers’ compensation benefit accruals are actuarially determined and are subject to the existing workers’ compensation laws that vary by location. Accruals for workers’ compensation benefits represent the discounted future cash expenditures expected during the period between the incidents necessitating the employees to be idled and the time when such employees return to work, are eligible for retirement or otherwise terminate their employment.
Share-based Compensation, Policy	Share-based compensation —The Company’s share-based compensation arrangements primarily consist of the Aptiv PLC Long Term Incentive Plan, as amended and restated effective April 23, 2015 (the “PLC LTIP”), under which grants of restricted stock units (“RSUs”) have been made in each year prior to April 2024, and the 2024 Long-Term Incentive Plan (the “2024 LTIP”), under which grants of RSUs were made beginning in April 2024. The RSU awards include a time-based vesting portion and a performance-based vesting portion. The performance-based vesting portion includes performance and market conditions in addition to service conditions. The grant date fair value of the RSUs is determined based on the closing price of the Company’s ordinary shares on the date of the grant of the award, including an estimate for forfeitures, or a contemporaneous valuation performed by a third-party valuation specialist with respect to awards with market conditions. Compensation expense is recognized based upon the grant date fair value of the awards applied to the Company’s best estimate of ultimate performance against the respective targets on a straight-line basis over the requisite vesting period of the awards. The performance conditions require management to make assumptions regarding the likelihood of achieving certain performance goals. Changes in these performance assumptions, as well as differences in actual results from management’s estimates, could result in estimated or actual values different from previously estimated fair values. Refer to Note 21. Share-Based Compensation for additional information.
Business Combinations, Policy	Business combinations —The Company accounts for its business combinations in accordance with the accounting guidance in FASB ASC 805, Business Combinations . The purchase price of an acquired business is allocated to its identifiable assets and liabilities based on estimated fair values. The excess of the purchase price over the amount allocated to the assets and liabilities, if any, is recorded as goodwill. Determining the fair values of assets acquired and liabilities assumed requires management’s judgment, the utilization of independent appraisal firms and often involves the use of significant estimates and assumptions with respect to the timing and amount of future cash flows, market rate assumptions, actuarial assumptions, and appropriate discount rates, among other items. Refer to Note 20. Acquisitions and Divestitures for additional information.
Government incentives, Policy	Government incentives —From time to time, Aptiv receives government incentives in the form of cash grants and other incentives in return for past or future compliance with certain conditions. The Company accounts for funds received from government grants that are not in the form of an income tax credit, revenue from a contract with a customer or a loan, by analogy to International Accounting Standards 20, Accounting for Government Grants and Disclosure of Government Assistance . Accordingly, we recognize funds we receive from government grants in the consolidated statements of operations when there is reasonable assurance that Aptiv will comply with the conditions associated with the grant and the grants will be received. Recognition occurs on a systematic basis over the periods in which Aptiv recognizes, as expenses, the related costs for which the grants are intended to defray. Aptiv is eligible to receive certain government grants because we engage in qualifying capital investments and other activities as defined by the relevant governmental entities awarding the grants. Typically, grant agreements require that Aptiv complies with certain conditions, including committing to minimum levels of capital investment and maintenance of a minimum level of headcount at the impacted manufacturing site. Aptiv generally recognizes government grants of an operating nature as a reduction to operating expenses (primarily cost of sales Aptiv records capital-related grants as a reduction to property, plant and equipment, net in the consolidated balance sheets, which ultimately results in a reduction to depreciation expense over the useful life of the corresponding asset. Capital-related grants reduced gross property, plant and equipment by approximately $5 million during the year ended December 31, 2024. Amounts recorded as due from and due to governmental entities in the consolidated balance sheets were not significant for any period presented. Our agreements with governmental entities have an average duration of seven years and certain of these agreements include provisions for the recapture of funding if the Company fails to comply with various aspects of the agreement.
Recently Adopted Accounting Pronouncements, Policy	Recently adopted accounting pronouncements —Aptiv adopted Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, in the fourth quarter of 2024. The amendments in this update require public entities to disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker (the “CODM”) and which are included within each reported measure of segment profit or loss as well as disclosure of other segment items and a description of their composition. The amendments also require public entities to disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. The adoption of this guidance resulted in incremental disclosures in the Company’s financial statements. Recently issued accounting pronouncements not yet adopted —In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses . The amendments in this update require public entities to disclose, on an annual and interim basis, disaggregated information about certain income statement expenses, including purchases of inventory, employee compensation, depreciation, intangible asset amortization and depletion, that are included in each relevant income statement expense line item. The amendments also require qualitative descriptions of the amounts remaining in relevant expense line items not separately disaggregated quantitatively. Certain amounts already disclosed under existing U.S. GAAP are required to be included in the same disclosure as the other disaggregated income statement expense line items. In addition, the amendments require disclosure of the total amount of selling expenses and, in annual reporting periods, an entity’s definition of those expenses. The new guidance will be applied prospectively and is effective for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The adoption of this guidance is expected to result in incremental disclosures in the Company’s financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures . The amendments in this update require public entities to disclose specific categories in the effective tax rate reconciliation, as well as additional information for reconciling items that exceed a quantitative threshold. The amendments also require all entities to disclose income taxes paid disaggregated by federal, state and foreign taxes, and further disaggregated for specific jurisdictions that exceed 5% of total income taxes paid, among other expanded disclosures. The new guidance will be applied prospectively and is effective for fiscal years beginning after December 15, 2024, with the option to apply retrospectively. Early adoption is permitted. The adoption of this guidance is expected to result in incremental disclosures in the Company’s financial statements. In August 2023, the FASB issued ASU 2023-05, Business Combinations - Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement . The amendments in this update require a joint venture to initially recognize all contributions received at fair value upon formation. The new guidance is applicable to joint venture entities with a formation date on or after January 1, 2025 and is to be applied prospectively. Early adoption is permitted. The adoption of this guidance is not expected to have a significant impact on Aptiv’s consolidated financial statements.
Pensions, Policy	Certain of Aptiv’s non-U.S. subsidiaries sponsor defined benefit pension plans, which generally provide benefits based on negotiated amounts for each year of service. Aptiv’s primary non-U.S. plans are located in France, Germany, Mexico, Portugal and the United Kingdom (“U.K.”). The U.K. and certain Mexican plans are funded. In addition, Aptiv has defined benefit plans in South Korea, Turkey and Italy for which amounts are payable to employees immediately upon separation. The obligations for these plans are recorded over the requisite service period. Aptiv sponsors a Supplemental Executive Retirement Program (“SERP”) for those employees who were U.S. executives of the former Delphi Corporation prior to September 30, 2008 and were still U.S. executives of the Company on October 7, 2009, the effective date of the program. This program is unfunded. Executives receive benefits over five years after an involuntary or voluntary separation from Aptiv. The SERP is closed to new members.
Fair Value Measurement, Policy	Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value measurements are based on one or more of the following three valuation techniques: Market —This approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. Income —This approach uses valuation techniques to convert future amounts to a single present value amount based on current market expectations. Cost —This approach is based on the amount that would be required to replace the service capacity of an asset (replacement cost). Aptiv uses the following fair value hierarchy prescribed by U.S. GAAP, which prioritizes the inputs used to measure fair value as follows: Level 1 —Unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 —Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 —Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Typically, assets and liabilities are considered to be fair valued on a recurring basis if fair value is measured regularly. However, if the fair value measurement of an instrument does not necessarily result in a change in the amount recorded on the consolidated balance sheets, assets and liabilities are considered to be fair valued on a nonrecurring basis. This generally occurs when accounting guidance requires assets and liabilities to be recorded at the lower of cost or fair value, or assessed for impairment.
Segment Reporting, Policy	The accounting policies of the segments are the same as those described in Note 2. Significant Accounting Policies, except that the disaggregated financial results for the segments have been prepared using a management approach, which is consistent with the basis and manner in which management internally disaggregates financial information for which Aptiv’s chief operating decision maker (“CODM”), who is the Company’s chairman and chief executive officer, regularly reviews financial results to assess performance of, and make internal operating decisions about allocating resources to, the segments. Generally, Aptiv evaluates segment performance based on stand-alone segment net income before interest expense, other income (expense), net, income tax (expense) benefit, equity income (loss), net of tax, amortization, restructuring, other acquisition and portfolio project costs (which includes costs incurred to integrate acquired businesses and to plan and execute product portfolio transformation actions, including business and product acquisitions and divestitures), asset impairments and other related charges, compensation expense related to acquisitions and gains (losses) on business divestitures and other transactions (“Adjusted Operating Income”). Aptiv’s management, including the CODM, utilizes Adjusted Operating Income as the key performance measure of segment income or loss to evaluate segment performance, and for planning and forecasting purposes to allocate resources to the segments, as management believes this measure is most reflective of the operational profitability or loss of Aptiv’s operating segments. The CODM regularly evaluates budget-to-actual and period-over-period variances for this metric when making decisions about the allocation of operating and capital resources to each segment. The CODM also uses Adjusted Operating Income in evaluating the operating performance of each segment and as part of determining the compensation of the segment managers and certain other employees. Segment Adjusted Operating Income should not be considered a substitute for results prepared in accordance with U.S. GAAP and should not be considered an alternative to net income attributable to Aptiv, which is the most directly comparable financial measure to Adjusted Operating Income that is prepared in accordance with U.S. GAAP. Segment Adjusted Operating Income, as determined and measured by Aptiv, should also not be compared to similarly titled measures reported by other companies.
