Preliminary Prospectus Supplement

(To Prospectus dated February 9, 2022)

€     % Senior Notes due 20    

Aptiv PLC, a public limited company incorporated under the laws of Jersey (the “Issuer”), and Aptiv Global Financing Limited, incorporated in Ireland and an indirect subsidiary of Aptiv PLC (the “Co-Obligor” and, together with Aptiv PLC, the “Issuers”), are offering €    of     % Senior Notes due 20     (the “Notes”). The Notes will mature on      , 20     . The Issuers will pay interest on the Notes annually in arrears on     of each year, beginning on     , 2025. Interest on the Notes will accrue from     , 2024.

The Issuers may, at their option, redeem all or part of the Notes at any time at the redemption prices described herein. See “Description of Notes—Optional Redemption.” In addition, the Issuers may, at their option, redeem all, but not a part, of the Notes at any time in the event of certain developments affecting taxation as described herein. See “Description of Notes—Tax Redemption.” If the Issuers experience a change of control triggering event (as described herein), the Issuers must offer to repurchase the Notes. See “Description of Notes—Change of Control Triggering Event.”

The obligations under the Notes will initially be fully and unconditionally guaranteed by Aptiv Corporation, a Delaware corporation and an indirect subsidiary of Aptiv PLC (the “Guarantor”). The Notes and the guarantees will be general unsecured obligations of the Issuers and the Guarantor, respectively, and will rank equally in right of payment with all of the Issuers’ and the Guarantor’s respective existing and future senior indebtedness, including all of Aptiv PLC’s outstanding notes, which are also issued or guaranteed by Aptiv Corporation and Aptiv Global Financing Limited. The Notes and the guarantees will be effectively subordinated to any of the Issuers’ and the Guarantor’s respective future secured debt to the extent of the value of the collateral securing such indebtedness. The Notes will be structurally subordinated to all liabilities of the Issuers’ respective subsidiaries.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

Investing in the Notes involves risks. See “Risk Factors“ beginning on page S-6 of this prospectus supplement, as well as the risks set forth in our other filings with the Securities and Exchange Commission that are incorporated by reference in this prospectus supplement and the accompanying prospectus.

The Issuers intend to apply to list the Notes on the New York Stock Exchange (the “NYSE”). If such a listing is obtained, the Issuers will have no obligation to maintain such listing, and the Issuers may delist the Notes at any time. There is currently no established trading market for the Notes.

The Issuers expect that delivery of the Notes will be made to investors in book-entry form only through a common depositary of Euroclear Bank SA/NV (“Euroclear”) and Clearstream Banking, société anonyme (“Clearstream”), on or about     , 2024.

The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom (“UK”).

UK MIFIR Product Governance / Professional Investors and ECPs Only Target Market

Solely for the purposes of each manufacturer’s product approval process, the target market assessment in respect of the Notes has led to the conclusion that: (i) the target market for the Notes is only eligible counterparties, as defined in the FCA Handbook Conduct of Business Sourcebook (“COBS”), and professional clients, as defined in Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (“UK MiFIR”); and (ii) all channels for distribution of the Notes to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the Notes (a “UK distributor”) should take into consideration the manufacturers’ target market assessment; however, a UK distributor subject to the FCA Handbook Product Intervention and Product Governance Sourcebook is responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining the manufacturer’s target market assessment) and determining appropriate distribution channels.

SPECIAL NOTE ON FORWARD-LOOKING STATEMENTS

This prospectus supplement, including the documents incorporated by reference in this prospectus supplement and accompanying prospectus, contains forward-looking statements that reflect, when made, our current views with respect to current events, certain investments and acquisitions and financial performance. Such forward-looking statements are subject to many risks, uncertainties and factors relating to our operations and business environment, which may cause our actual results to be materially different from any future results, express or implied, by such forward-looking statements. All statements that address future operating, financial or business performance or our strategies or expectations are forward-looking statements. In some cases, you can identify these statements by forward-looking words such as “may,” “might,” “will,” “should,” “expects,” “plans,” “intends,” “anticipates,” “believes,” “estimates,” “predicts,” “projects,” “potential,” “outlook” or “continue,” and other comparable terminology. Factors that could cause actual results to differ materially from these forward-looking statements include, but are not limited to, the following: global and regional economic conditions, including conditions affecting the credit market; global inflationary pressures; uncertainties created by the conflict between Ukraine and Russia, and its impacts to the European and global economies and our operations in each country; uncertainties created by the conflicts in the Middle East and their impacts on global economies;

S-v

fluctuations in interest rates and foreign currency exchange rates; the cyclical nature of global automotive sales and production; the potential disruptions in the supply of and changes in the competitive environment for raw material and other components integral to our products, including the ongoing semiconductor supply shortage; our ability to maintain contracts that are critical to our operations; potential changes to beneficial free trade laws and regulations, such as the United States-Mexico-Canada Agreement; changes to tax laws; future significant public health crises; our ability to integrate and realize the expected benefits of recent transactions; our ability to attract, motivate and/or retain key executives; our ability to avoid or continue to operate during a strike, or partial work stoppage or slow down by any of our unionized employees or those of our principal customers; and our ability to attract and retain customers. Additional factors are discussed under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our filings with the Securities and Exchange Commission, including those set forth in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 and our Quarterly Report on Form 10-Q for the three months ended March 31, 2024. New risks and uncertainties arise from time to time, and it is impossible for us to predict these events or how they may affect us. We disclaim any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events and/or otherwise, except as may be required by law.

Although we believe the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, level of activity, performance or achievements. Moreover, neither we nor any other person assumes responsibility for the accuracy and completeness of any of these forward-looking statements. We are under no duty to update any of these forward-looking statements after the date of this prospectus supplement to conform our prior statements to actual results or revised expectations.

RISK FACTORS

Investing in the Notes involves risks. You should carefully consider all the information set forth in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein before deciding to invest in the Notes. In particular, we urge you to carefully consider the risk factors set forth below as well as those under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2023 incorporated by reference in this prospectus supplement and the accompanying prospectus.

Risks Related to the Notes

Holders of the Notes will receive payments solely in euro except under the limited circumstances provided herein.

All payments of interest on and the principal of the Notes and any redemption price for, or Additional Amounts with respect to, the Notes will be made in euro except under the limited circumstances provided herein. See “Description of Notes—Issuance in Euro; Currency Conversion.” We, the underwriters, the trustee and the paying agent with respect to the Notes will not be obligated to convert, or to assist any registered owner or beneficial owner of such Notes in converting, payments of interest, principal, any redemption price or any Additional Amounts in euro made with respect to such Notes into U.S. dollars or any other currency.

Holders of the Notes may be subject to certain risks relating to the euro, including the effects of foreign currency exchange rate fluctuations, as well as possible exchange controls.

The initial investors in the Notes will be required to pay for the Notes in euro. Neither we nor the underwriters will be obligated to assist the initial investors in obtaining euro or in converting other currencies into euro to facilitate the payment of the purchase price for the Notes.

An investment in any security denominated in, and all payments with respect to which are to be made in, a currency other than the currency of the country in which an investor in the Notes resides or the currency in which an investor conducts its business or activities (the “investor’s home currency”), entails significant risks not associated with a similar investment in a security denominated in the investor’s home currency. In the case of the Notes offered hereby, these risks may include the possibility of:

We have no control over a number of factors affecting the Notes and foreign exchange rates, including economic, financial and political events that are important in determining the existence, magnitude and longevity of these risks and their effects. Changes in foreign currency exchange rates between two currencies result from the interaction over time of many factors directly or indirectly affecting economic and political conditions in the countries issuing such currencies, and economic and political developments globally and in other relevant countries. Foreign currency exchange rates may be affected by, among other factors, existing and expected rates of inflation, existing and expected interest rate levels, the balance of payments between countries and the extent of governmental surpluses or deficits in various countries. All of these factors are, in turn, sensitive to the monetary, fiscal and trade policies pursued by the governments of various countries important to international trade and finance. Moreover, the recent global economic crisis and the actions taken or to be taken by various national governments in response to the crisis as well as market perceptions concerning the instability of the euro could significantly affect the exchange rates between the euro and the investor’s home currency.

S-6

The exchange rates of an investor’s home currency for euro and the fluctuations in those exchange rates that have occurred in the past are not necessarily indicative of the exchange rates or the fluctuations therein that may occur in the future. Depreciation of the euro against the investor’s home currency would result in a decrease in the investor’s home currency equivalent yield on a note, in the investor’s home currency equivalent of the principal payable at the maturity of that note and generally in the investor’s home currency equivalent market value of that note. Appreciation of the euro in relation to the investor’s home currency would have the opposite effects.

The European Union or one or more of its member states may, in the future, impose exchange controls and modify any exchange controls imposed, which controls could affect exchange rates, as well as the availability of euro at the time of payment of principal of, interest on, or any redemption payment or Additional Amounts with respect to, the Notes.

Furthermore, the indenture is, and the Notes will be, governed by the laws of the State of New York. Under New York law, a New York state court rendering a judgment on the Notes would be required to render the judgment in euro. However, the judgment would be converted into U.S. dollars at the exchange rate prevailing on the date of entry of the judgment. Consequently, in a lawsuit for payment on the Notes, investors would bear currency exchange risk until a New York state court judgment is entered, and we cannot predict how long this would take. A federal court sitting in New York with diversity jurisdiction over a dispute arising in connection with the Notes would apply the foregoing New York law. In courts outside of New York, investors may not be able to obtain a judgment in a currency other than U.S. dollars. For example, a judgment for money in an action based on the Notes in many other U.S. federal or state courts ordinarily would be rendered in the United States only in U.S. dollars. The date used to determine the rate of conversion of euro into U.S. dollars would depend upon various factors, including which court renders the judgment and when the judgment is rendered.

This description of foreign exchange risks does not describe all the risks of an investment in securities, including, in particular, the Notes, that are denominated or payable in a currency other than an investor’s home currency. You should consult your own financial, legal and tax advisors as to the risks involved in an investment in the Notes.

The Notes permit us to make payments in U.S. dollars if we are unable to obtain euro, which could adversely affect the value of the Notes.

If, as described under “Description of Notes—Issuance in Euro; Currency Conversion,” the euro is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the Notes will be made in U.S. dollars until the euro is again available to us or so used. In such circumstances, the amount payable on any date in euro will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second business day prior to the relevant payment date or, in the event the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the then most recent U.S. dollar/euro exchange rate available on or prior to the second business day prior to the relevant payment date as determined by us in our sole discretion. There can be no assurance that this exchange rate will be as favorable to holders of Notes as the exchange rate otherwise determined by applicable law. These potential developments, or market perceptions concerning these and related issues, could adversely affect the value of the Notes.

Trading in the clearing systems is subject to minimum denomination requirements.

The Notes will be issued only in minimum denominations of €100,000 and integral multiples of €1,000 in excess thereof. It is possible that the clearing systems may process trades which could result in amounts being

S-7

held in denominations smaller than the minimum denominations. If definitive notes are required to be issued in relation to such notes in accordance with the provisions of the relevant global notes, a holder who does not have the minimum denomination or an integral multiple of €1,000 in excess thereof in its account with the relevant clearing system at the relevant time may not receive all of its entitlement in the form of definitive notes unless and until such time as its holding satisfies the minimum denomination requirement.

Our debt exposes us to certain risks.

As of March 31, 2024, after giving effect to this offering and the application of the net proceeds therefrom, the total indebtedness of the Issuers and the Guarantor would have been $     million. Our indebtedness could have important consequences, including:

Despite the level of our indebtedness, we may still incur significantly more indebtedness. This could further increase the risks associated with our indebtedness.

Despite our current level of indebtedness, we and our subsidiaries may be able to incur significant additional indebtedness, including secured indebtedness, in the future. For example, we had no drawings and $2 billion of available borrowings under our revolving credit facility as of March 31, 2024. Additionally, the Notes offered hereby contain no restrictive covenants on our ability to incur more debt. If new indebtedness is added to our and our subsidiaries’ current debt levels, the related risks that we and they face would be increased, and we may not be able to meet all our debt obligations, including the Issuers’ repayment of the Notes, in whole or in part.

We may not be able to generate sufficient cash from operations to service our debt.

Our ability to make payments on, and to refinance, our indebtedness and to fund planned capital expenditures and research and development efforts will depend on our ability to generate cash in the future and our ability to borrow under our credit agreement to the extent of available borrowings. This, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control. If economic conditions worsen, we could experience decreased revenues from our operations and could fail to generate sufficient cash to fund our liquidity needs or fail to satisfy the restrictive covenants and borrowing limitations which we are subject to under certain of our indebtedness.

Based on our current and expected level of operations, we believe our cash flow from operations, available cash and available borrowings under our credit agreement will be adequate to meet our future liquidity needs. We cannot assure you, however, that our business will generate sufficient cash flow from operations or that future borrowings will be available to us under our credit agreement or otherwise in an amount sufficient to enable us to pay our indebtedness or to fund our other liquidity needs. We may need to refinance all or a portion of our

S-8

indebtedness on or before the maturity thereof. We cannot assure you that we will be able to refinance any of our indebtedness on commercially reasonable terms or at all. If we cannot service our indebtedness, we may have to take actions such as selling assets, seeking equity or reducing or delaying capital expenditures, strategic acquisitions, investments and alliances. We cannot assure you that any such actions, if necessary, could be effected on commercially reasonable terms or at all.

If we default on our obligations to pay our other indebtedness, the Issuers may not be able to make payments on the Notes.

Any default under the agreements governing our indebtedness, including a default under our credit agreement or under the indentures governing our existing notes, that is not waived by the required lenders or holders of such indebtedness, and the remedies sought by the holders of such indebtedness could prevent the Issuers from paying principal and interest on the Notes and substantially decrease the market value of the Notes. If we are unable to generate sufficient cash flow or are otherwise unable to obtain funds necessary to meet required payments of principal and interest on our indebtedness, or if we otherwise fail to comply with the various covenants in the agreements governing our indebtedness, including the covenants contained in our credit agreement and in the indentures governing our existing notes, we would be in default under the terms of the agreements governing such indebtedness. In the event of such a default under our credit agreement:

As a result of such default and any actions the lenders may take in response thereto, we could be forced into bankruptcy or liquidation.

Your rights as a holder of the Notes are effectively subordinated to claims of creditors of our subsidiaries, other than the Co-Obligor and the Guarantor, which are not obligors under the Notes.

On the issue date, none of our subsidiaries other than the Co-Obligor and the Guarantor will be obligors under the Notes. The Issuers will not be required under the indenture for the Notes to add subsidiary Guarantors in the future. As a result, you will be creditors of only the Issuers and the Guarantor. Substantially all of our operations are conducted by subsidiaries, which, other than the Co-Obligor and the Guarantor, will not be obligors under the Notes on the issue date. All of the existing and future liabilities of those other subsidiaries, including any claims of trade creditors, debtholders and preferred stockholders, if any, will be effectively senior to your claim as a holder of the Notes and related guarantees, meaning creditors of such subsidiaries generally will have priority with respect to the assets and earnings of such subsidiaries over the claims of our other creditors, including holders of the Notes. Our subsidiaries may incur significant additional indebtedness in the future. In the event of a bankruptcy, liquidation or reorganization of any of our non-guarantor subsidiaries, their creditors will be entitled to payment of their claims from the assets of those subsidiaries before any assets are made available for distribution to us. The indenture will not limit the ability of our non-guarantor subsidiaries to incur debt or other liabilities.

Our non-guarantor subsidiaries contribute substantially all of our revenues and operating income, and had total assets of $ 23,357 million and total liabilities of $ 5,967 million, including total debt of $ 39 million, or 99% of our total assets and 49% of our total liabilities, as of March 31, 2024 (giving effect to intercompany eliminations).

S-9

The Notes are obligations of the Issuer, the Co-Obligor and the Guarantor only, but our operations are conducted through, and a substantial portion of our consolidated assets are held by, subsidiaries other than the Co-Obligor and the Guarantor.

The Notes are obligations of the Issuer, the Co-Obligor and the Guarantor only. A substantial portion of our consolidated assets are held by our non-guarantor subsidiaries, which means that our ability to service our debt, including the Notes, depends on the results of operations of their subsidiaries and upon the ability of those subsidiaries to provide us with cash, whether in the form of dividends, loans or otherwise, to pay amounts due on our obligations, including the Notes. Our subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to make payments on the Notes or to make any funds available for that purpose. In addition, dividends, loans or other distributions to us from such subsidiaries may be subject to contractual and other restrictions and are subject to other business considerations.

The Notes will be subject to a change of control triggering event provision, and the Issuers may not have the ability to raise the funds necessary to fulfill their respective obligations under the Notes following a change of control triggering event.

The Issuers may not have the ability to raise the funds necessary to fulfill their respective obligations under the Notes following a “change of control triggering event” as defined in the indenture governing the Notes. Under the indenture, upon the occurrence of a change of control triggering event, the Issuers will be required to offer to repurchase all outstanding Notes at 101% of the principal amount thereof plus accrued and unpaid interest to the date of repurchase. However, the Issuers may not have sufficient funds at the time of the change of control triggering event to make the required repurchase of the Notes. The Issuers’ failure to make or complete a change of control offer would place the Issuers in default under the indenture governing the Notes. In addition, certain change of control events are an event of default under our credit agreement, so the Issuers would need to repay any debt then outstanding thereunder or obtain the requisite consents from the lenders thereunder. However, there can be no assurance that the Issuers would be able to repay such debt or obtain such consents at such time.

The Notes will be unsecured and rank behind any of the Issuers’ and the Guarantor’s respective future secured creditors to the extent of the value of the collateral securing their claims.

At March 31, 2024, the Issuers and the Guarantor had no secured debt. However, subject to limits in the indenture we may incur secured debt. Holders of any future secured indebtedness of the Issuers and the Guarantor will have claims that are prior to your claims as holders of the Notes to the extent of the value of the assets securing such indebtedness. In the event of any distribution or payment in respect of the Issuers’ or the Guarantor’s assets in any foreclosure, dissolution, winding-up, liquidation, reorganization or other bankruptcy proceeding, holders of the Issuers’ or the Guarantor’s secured indebtedness will have prior claims to the assets that constitute their collateral. If any of these events occurs, the secured creditors could sell those of the assets in which they have been granted a security interest, to your exclusion, even if an event of default exists under the indenture governing the Notes at such time. Only when the applicable secured debt obligations are satisfied in full will the proceeds of the collateral securing such indebtedness be available to satisfy obligations under the Notes. Holders of the Notes will participate ratably with all holders of the Issuers’ and the Guarantor’s respective unsecured indebtedness that is deemed to rank equally with the Notes, based upon the respective amount owed to each creditor. Upon the occurrence of any of the aforementioned events, because the Notes will not be secured by any of the Issuers’ or the Guarantor’s assets, it is possible that any remaining assets might be insufficient to satisfy your claims in full.

An active trading market may not develop for these Notes, which may make it more difficult to sell and accurately price the Notes.

The Notes are a new issue of securities. There are no established public trading markets for the Notes and active trading markets may not develop. Although the Issuers expect the Notes to be listed for trading on the

S-10

NYSE, no assurance can be given that the Notes will become or remain listed, that trading markets for the Notes will develop or of the price at which investors may be able to sell the Notes, if at all. In addition, if such listings are obtained, the Issuers will have no obligation to maintain such listings, and the Issuers may delist the Notes at any time. The underwriters have advised the Issuers that they intend to make markets in the Notes after the Issuers complete this offering. However, the underwriters are not obligated to do so and may cease their market-making activities at any time. The liquidity of the trading markets in the Notes, and the market prices quoted for the Notes, may be adversely affected by changes in the overall markets for these types of securities and by changes in our financial performance or prospects or in the prospects for companies in our industries generally. As a result, the Issuers cannot assure you that active trading markets will develop for the Notes.

A downgrade, suspension or withdrawal of the rating assigned by a rating agency to our company or the Notes, if any, could cause the liquidity or market values of the Notes to decline.

The Notes have been rated by nationally recognized rating agencies and may in the future be rated by additional rating agencies. The Issuers cannot assure you that any rating assigned will remain for any given period of time or that a rating will not be lowered or withdrawn entirely by a rating agency if, in that rating agency’s judgment, circumstances relating to the basis of the rating, such as adverse changes in our business, so warrant. Any downgrade, suspension or withdrawal of a rating by a rating agency (or any anticipated downgrade, suspension or withdrawal) could reduce the liquidity or market values of the Notes.

Any future lowering of our ratings may make it more difficult or more expensive for the Issuers to obtain additional debt financing. If any credit rating initially assigned to the Notes is subsequently lowered or withdrawn for any reason, you may not be able to resell your Notes without a substantial discount.

The indenture will contain only limited covenants for the benefit of the Notes.

The indenture governing the Notes will contain limited covenants, including those restricting our ability and our subsidiaries’ ability to create certain liens, and enter into certain sale and leaseback transactions. The limitation on liens and limitation on sale and leaseback covenants will contain exceptions that will allow us and our subsidiaries to incur liens with respect to certain material assets. See “Description of Notes—Certain Covenants.” In light of these exceptions, holders of the Notes may be structurally or contractually subordinated to new lenders. In addition, the covenants will not limit our ability to repurchase stock or pay dividends. We currently have an ordinary share repurchase program in place, and we paid regular quarterly dividends on our ordinary shares from the first quarter of 2013 until the first quarter of 2020. During the first quarter of 2020, we suspended dividend payments due to the COVID-19 pandemic, but we may decide to resume paying dividends at any time.

For purposes of voting under the indenture governing the Notes, the Notes offered hereby and all other debt securities issued thereunder will generally constitute a single class of debt securities. Therefore, any action under the indenture governing the Notes other than those actions affecting only the Notes will require the consent of the holders of a majority in aggregate principal amount of the debt securities issued thereunder that are affected thereby. See “Description of Notes—Amendments and Waivers.” Consequently, any action requiring the consent of holders of the Notes under the indenture governing the Notes may also require the consent of holders of a significant portion of the remaining debt securities issued thereunder, and the individual voting interest of each holder of the Notes may be accordingly diluted with respect to such actions. In addition, holders of debt securities could vote in favor of certain actions under the indenture that holders of the Notes vote against, and the requisite consent to such action could be received nonetheless. The Issuers also may, from time to time, issue additional debt securities under the indenture governing the Notes which could further dilute the individual voting interest of each holder of the Notes with respect to such actions.

S-11

The Notes and other securities of other series under the Indenture will vote together as a single class in many circumstances. The principal amount of the Notes and such other securities for purposes of any act, consent or waiver under the Indenture shall be determined as the dollar equivalent thereof, converted based on the spot rate (as determined by us in our discretion) at 11:00 a.m. on the business day before the record date for such act, waiver or consent (or, if there is no such record date, the date when such act, consent or waiver is taken).

USE OF PROCEEDS

We estimate that the net proceeds from this offering will be approximately €     million or $    million, based on the euro/U.S. $ exchange rate of €1.00 = U.S. $    as of     , 2024, as published by Bloomberg L.P., after deducting the underwriting discounts and our estimated offering expenses.

We expect to use the net proceeds from this offering to repay the 2025 Euro Notes in full prior to their maturity, with any remaining net proceeds to be used for general corporate purposes. As of March 31, 2024, €700 million of the 2025 Euro Notes was outstanding. The 2025 Euro Notes have a fixed interest rate coupon of 1.500% and mature on March 10, 2025. Pending final use, we may hold the net proceeds from this offering in cash or deposit accounts or invest the net proceeds from this offering in short-term marketable securities.

DESCRIPTION OF NOTES

Definitions of certain terms used in this Description of Notes may be found under the heading “—Certain Definitions.” For purposes of this section, the term “Company” refers only to Aptiv International Holdings (UK) LLP (and its successors), Aptiv PLC’s directly owned subsidiary, and not to any of its subsidiaries; the term “Aptiv” refers only to Aptiv PLC and not to any of its subsidiaries; the term “Co-Obligor” refers only to Aptiv Global Financing Limited (“AGFL”) and not to any of its subsidiaries; the term “Issuers” refers to Aptiv PLC and Aptiv Global Financing Limited; the terms “we,” “our” and “us” refer to the Issuers and, unless the context otherwise requires, their respective subsidiaries. The Notes will initially be guaranteed (the “Note Guarantee”) by Aptiv Corporation, an indirect subsidiary of Aptiv PLC. Aptiv Corporation is referred to as the “Guarantor.”

We will issue the     % Senior Notes due 20     (the “Notes”) pursuant to the Senior Notes Indenture, dated as of March 10, 2015 (the “Base Indenture”), as supplemented by a tenth supplemental indenture, to be dated as of     , 2024 (the “Tenth Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), among the Issuers, the Guarantor, Wilmington Trust, National Association, as trustee (the “Trustee”) and Deutsche Bank Trust Company Americas, as a registrar, paying agent and authenticating agent (the “Registrar”, “Paying Agent” and “Authenticating Agent”). The Notes will be issued as a separate series under the Indenture.

The Notes will be in the form of one or more global notes that we will deposit with or on behalf of a common depositary for the accounts of Clearstream and Euroclear (each as defined below) and will be registered in the name of the nominee of the common depositary. See “Book-entry, Delivery and Form.”

The Indenture contains provisions which define your rights under the Notes. In addition, the Indenture governs the obligations of the Issuers and the Guarantor under the Notes. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the TIA.

The following description is meant to be only a summary of the provisions of the Indenture that we consider material. It does not restate the terms of the Indenture in their entirety. We urge that you carefully read the Indenture because the Indenture, and not this description, governs your rights as holders. You may request copies of the Indenture at our address set forth above under the heading “Where You Can Find More Information.”

Overview of the Notes

The Notes:

Principal, Maturity and Interest

The Issuers will initially issue the Notes in an aggregate principal amount of €    . The Notes will mature on     , 20    . The Notes will bear interest at a rate of     % per annum from the Issue Date or from the most recent date to which interest has been paid or provided for.

The Issuers will pay interest on the Notes annually to Holders of record at the close of business on the immediately preceding the interest payment date on      of each year. The first interest payment date for

S-16

the Notes will be     , 2025. Interest on the Notes will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the date from which interest begins to accrue for the period (or from the Issue Date if no interest has been paid on the Notes) to, but excluding the next scheduled interest payment date. This payment convention is referred to as Actual/Actual (ICMA) as defined in the rulebook of the International Capital Markets Association.

We will issue the Notes in fully registered form, without coupons, in minimum denominations of €100,000 and integral multiples of €1,000 in excess thereof.

Issuance in Euro; Currency Conversion

Initial holders will be required to pay for the Notes in euro, and all payments of interest and principal, including payments made upon any redemption of the Notes, will be payable in euro. If, on or after the issuance of the Notes, the euro is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the Notes will be made in U.S. dollars until the euro is again available to us or so used. In such circumstances, the amount payable on any date in euro will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second business day prior to the relevant payment date or, in the event the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the then most recent U.S. dollar/euro exchange rate available on or prior to the second business day prior to the relevant payment date as determined by us in our sole discretion. Any payment in respect of the Notes so made in U.S. dollars will not constitute an event of default under the Notes or the indenture governing the Notes. Neither the Trustee nor the Paying Agent shall have any responsibility for any calculation or conversion in connection with the foregoing. Investors will be subject to foreign exchange risks as to payments of principal and interest, including payments made upon any redemption of the Notes, that may have important economic and tax consequences to them. See “Risk Factors.”

As of     , 2024, the euro/U.S. $ exchange rate was €1.00 = U.S. $    , as published by Bloomberg L.P.

The Notes and other securities of other series under the Indenture will vote together as a single class in many circumstances. To the extent that any other securities are issued under the Indenture and denominated in a currency other than euro, the principal amount of the Notes and such other securities for purposes of any act, consent or waiver under the Indenture shall be determined as the dollar equivalent thereof, converted based on the spot rate (as determined by us in our discretion) at 11:00 a.m. on the business day before the record date for such act, waiver or consent (or, if there is no such record date, the date when such act, consent or waiver is taken).

Indenture May Be Used For Future Issuances

We may issue additional Notes of the same series as the Notes offered hereby having identical terms and conditions to the Notes that the Issuers are currently offering (the “Additional Notes”) under the Indenture from time to time; provided, however, that if such Additional Notes are not fungible with the other Notes of the same series for U.S. federal income tax purposes, such Additional Notes will not have the same “CUSIP” or “ISIN” number, “Common Code” or other applicable identification number as the other Notes of such series (it being understood that, as described in the “—U.S. Federal Income Tax Treatment” section below, any Additional Notes that have a different allocation than the initial allocation with respect to the outstanding Notes shall not be considered as not fungible for U.S. federal income tax purposes under this proviso solely as a result of such difference in allocation). Any Additional Notes will be part of the same series as the Notes that the Issuers are currently offering and will vote on all matters with the Notes. We may also issue notes of different series under the Indenture from time to time.

S-17

Registrar and Paying Agent

The Issuers will pay the principal of, premium, if any, and interest on the Notes at any office of the Issuers or any agency designated by the Issuers. The Issuers have initially designated Deutsche Bank Trust Company Americas to act as the agent of the Issuers in such matters.

Holders may exchange or transfer their Notes at the Registrar and Paying Agent’s office. No service charge will be made for any registration or transfer or exchange of Notes. However, the Issuers may require Holders to pay any transfer tax or other similar governmental charge payable in connection with any such transfer or exchange.

Optional Redemption

Prior to    , 20     (    months prior to the maturity date of the Notes) (the “Par Call Date”), the Issuers may redeem the Notes, at their option, in whole or in part, at any time and from time to time, at a redemption price equal to the greater of:

plus, in each case, accrued and unpaid interest on the principal amount of the Notes to be redeemed to, but not including, the redemption date. The Comparable Government Bond Rate will be calculated on the third Business Day next preceding the date fixed for redemption (the “Calculation Date”).

On or after the Par Call Date, the Issuers may redeem the Notes, at their option, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest thereon to, but not including, the redemption date.

“Comparable Government Bond Rate” means the yield to maturity, expressed as a percentage (rounded to three decimal places, with 0.0005 being rounded upwards), on the third Business Day prior to the date fixed for redemption, of the Comparable Government Bond (as defined below) on the basis of the middle market price of the Comparable Government Bond prevailing at 11:00 a.m. (London time) on such Business Day as determined by an independent investment bank selected by us.

“Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, at the discretion of an independent investment bank selected by us, a German government bond whose maturity is closest to the maturity of the notes to be redeemed, or if such independent investment bank in its discretion determines that such similar bond is not in issue, such other German government bond as such independent investment bank may, with the advice of three brokers of, and/or market makers in, German government bonds selected by us, determine to be appropriate for determining the Comparable Government Bond Rate.

The Issuers’ actions and determinations in determining the redemption price for the Notes shall be conclusive and binding for all purposes, absent manifest error.

Notice of such redemption must be mailed by first-class mail to each Holder’s registered address, or delivered electronically if held by any depositary in accordance with such depositary’s customary procedures, not less than 10 nor more than 60 days prior to the redemption date. If the Issuer partially redeems the Notes, the Notes to be redeemed shall be selected pro rata in accordance with the applicable procedures of Clearstream or

S-18

Euroclear, although no Note less than €100,000 in original principal amount will be redeemed in part. If the Issuer redeems any Note in part only, the notice of redemption relating to such Note shall state the portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note. On and after the redemption date, interest will cease to accrue on Notes or portions thereof called for redemption so long as the Issuer has deposited with the Registrar and Paying Agent funds sufficient to pay the principal of the Notes to be redeemed, plus accrued and unpaid interest thereon. Any notice of redemption may be conditioned on the satisfaction of one or more conditions precedent.

Except as described above and as described in “—Tax Redemption” below, the Notes will not be redeemable by us prior to maturity. In addition, the Notes will not be entitled to the benefit of any sinking fund.

U.S. Federal Income Tax Treatment

On the Issue Date, all or a portion of the proceeds of the offering of the Notes will be borrowed by Aptiv Global Financing Limited and the remaining portion of the proceeds of the offering of the Notes, if any, will be borrowed by Aptiv. The portion of the proceeds of Notes that will be borrowed by Aptiv Global Financing Limited and the portion of the proceeds of Notes that will be borrowed by Aptiv, in each case, on the Issue Date, and after any subsequent change to such allocation (as discussed below), will be made available to a Holder or beneficial owner upon request by contacting Aptiv Investor Relations (which can be reached through Aptiv’s website or at ir@aptiv.com). Notwithstanding the foregoing or anything to the contrary in the Indenture, (x) each Holder and beneficial owner acknowledge that Aptiv Global Financing Limited and Aptiv have the right to change the foregoing allocations between Aptiv Global Financing Limited and Aptiv for any reason (including, but not limited, as a result of a redemption of any Notes or the issuance of Additional Notes, in each case, in a different allocation than the initial allocation with respect to the outstanding Notes), and (y) the Issuers are entitled (i) not to treat any Additional Notes that have a different allocation than the initial allocation with respect to the outstanding Notes as non-fungible for U.S. federal income tax purposes solely as a result of such different allocation, and (ii) to treat the issuance of Additional Notes as resulting in a change in the allocation of the outstanding Notes so as to have the same allocation across the Additional Notes and the outstanding Notes.

Note Guarantees

The Guarantor, as a primary obligor and not merely as a surety, will irrevocably and unconditionally guarantee on a senior unsecured basis the performance and full and punctual payment when due, whether at Stated Maturity, by acceleration or otherwise, of all obligations of the Issuers under the Indenture (including obligations to the Trustee and the Registrar and Paying Agent) and the Notes, whether for payment of principal of or interest on the Notes, expenses, indemnification or otherwise (all such obligations guaranteed by the Guarantor being herein called the “Guaranteed Obligations”). The Guarantor is 100% owned, directly or indirectly, by Aptiv.

The Guarantor will agree to pay, in addition to the amount stated above, any and all costs and expenses (including reasonable counsel fees and expenses) incurred by the Trustee in enforcing any rights under the Note Guarantee. The Note Guarantee will be limited in amount to an amount not to exceed the maximum amount that can be guaranteed by the Guarantor without rendering the Note Guarantee voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

The Note Guarantee is a continuing guarantee and shall (a) remain in full force and effect until payment in full of all the Guaranteed Obligations (subject to release as described below), (b) be binding upon the Guarantor and its successors and (c) inure to the benefit of, and be enforceable by, the Trustee, the Holders and their successors, transferees and assigns.

The Note Guarantee of the Guarantor will be released without any further action required on the part of the Trustee or any holder: (a) upon (i) the sale or other disposition (including by way of consolidation, merger,

S-19

dissolution or otherwise) of the Capital Stock of the Guarantor such that it is no longer a Subsidiary of either of the Issuers or (ii) the sale or other disposition of all or substantially all of the assets of the Guarantor; (b) when the Guarantor is no longer an obligor (whether as an issuer or guarantor) on any of Aptiv’s senior notes outstanding on the Issue Date; or (c) upon legal or covenant defeasance or satisfaction and discharge of the Notes.

The Issuers, at their option, may cause any other Subsidiary of the Issuers to become a Guarantor.

Ranking

The indebtedness evidenced by the Notes and the Note Guarantees is unsecured and ranks pari passu in right of payment to the senior indebtedness of each of the Issuers and the Guarantor, respectively. All of Aptiv’s currently outstanding notes are obligations of each of the Co-Obligor and the Guarantor.

The Notes are unsecured obligations of each of the Issuers. Secured debt and other secured obligations of each of the Issuers will be effectively senior to the Notes to the extent of the value of the assets securing such debt or other obligations.

As of March 31, 2024, after giving effect to the offering of the Notes, the Issuers and the Guarantor would have had total indebtedness of $    million.

Aptiv currently conducts substantially all of its operations through its subsidiaries. Creditors of such subsidiaries (other than the Co-Obligor and the Guarantor), including trade creditors, and preferred stockholders, if any, of such subsidiaries generally will have priority with respect to the assets and earnings of such subsidiaries over the claims of creditors of Aptiv, including Holders. The Notes, therefore, will be effectively subordinated to the claims of creditors, including trade creditors, and preferred stockholders, if any, of the subsidiaries of Aptiv other than the Co-Obligor or the Guarantor.

Our non-guarantor subsidiaries contribute substantially all of our revenues and operating income, and had total assets of $ 23,357 million and total liabilities of $ 5,967 million, including total debt of $ 39 million, or 99% of our total assets and 49% of our total liabilities, as of March 31, 2024 (giving effect to intercompany eliminations).

The Indenture does not limit the incurrence of indebtedness by each of the Issuers or any of their respective subsidiaries. Each of the Issuers and their respective subsidiaries may be able to incur substantial amounts of additional Indebtedness in certain circumstances.

Such Indebtedness may be senior indebtedness and, subject to the limitations under “—Certain Covenants—Limitation on Liens” below, may also be secured.

The Notes will rank equally in all respects with all other senior indebtedness of each of the Issuers. Unsecured Indebtedness is not deemed to be subordinate or junior to secured indebtedness merely because it is unsecured.

Change of Control Triggering Event

Upon the occurrence of a Change of Control Triggering Event, each Holder of Notes will have the right to require the Issuers to purchase all or any part of such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof plus accrued and unpaid interest to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

“Change of Control Triggering Event” means the occurrence of both a (1) Change of Control and (2) (i) the ratings of the Notes are downgraded by each of the Ratings Agencies during the 60-day period (the “Trigger Period”) commencing on the earlier of (x) the occurrence of such Change of Control or (y) the first public

S-20

announcement of the occurrence of such Change of Control or our intention to effect such Change of Control (which Trigger Period will be extended so long as the ratings of the Notes are under publicly announced consideration for possible downgrade by any of the Ratings Agencies) and (ii) the Notes are rated below an Investment Grade Rating by each of the Ratings Agencies on any date during the Trigger Period; provided that (x) a Change of Control Triggering Event will not be deemed to have occurred in respect of a particular Change of Control if each Ratings Agency does not publicly announce or confirm or inform the Trustee in writing at our request that the reduction was the result of the Change of Control (whether or not the applicable Change of Control has occurred at the time of the Change of Control Triggering Event) and (y) the Trigger Period will terminate with respect to each Ratings Agency when such Ratings Agency takes action (including affirming its existing ratings) with respect to such Change of Control. Notwithstanding the foregoing, no Change of Control Triggering Event will be deemed to have occurred in connection with any particular Change of Control unless and until such Change of Control has actually been consummated. The Trustee and Paying Agent are under no obligation to ascertain whether a Change of Control or any event that could lead to the occurrence of or could constitute a Change of Control has occurred, and until a responsible officer of the Trustee or Paying Agent, as applicable, has actual knowledge or express notice to the contrary, the Trustee and Paying Agent may conclusively assume that no Change of Control or other such event has occurred.

“Change of Control” means the occurrence of any of the following:

Notwithstanding the foregoing, a transaction will not be deemed to involve a Change of Control if (1) Aptiv becomes a direct or indirect Subsidiary of a holding company and (2) no person (as defined above) (other than a holding company) owns, directly or indirectly, a majority of the voting power of the Equity Interests of such holding company.

Within 30 days following any Change of Control Triggering Event, an Issuer shall (unless prior to such date such Change of Control Triggering Event ceases to exist) deliver by mail or electronic means a notice to each Holder of Notes with a copy to the Trustee (the “Change of Control Offer”) and the Paying Agent, stating:

The Issuers will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance

S-21

with the requirements set forth in the Indenture applicable to a Change of Control Offer made by the Issuers and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. In addition, the Issuers will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if the Notes have been or are called for redemption by the Issuers prior to them being required to deliver notice of the Change of Control Offer, and thereafter redeem all Notes called for redemption in accordance with the terms set forth in such redemption notice. Notwithstanding anything to the contrary contained herein, a revocable Change of Control Offer may be made in advance of a Change of Control Triggering Event, conditioned upon the consummation of the relevant Change of Control, if a definitive agreement is in place for such Change of Control at the time the Change of Control Offer is made.

The Issuers will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the purchase of Notes pursuant to this covenant. To the extent that the provisions of any securities laws or regulations conflict with provisions of this covenant, the Issuers will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this covenant by virtue thereof.

The Change of Control Triggering Event purchase feature is a result of negotiations between the Issuers and the underwriters. Management of Aptiv has no present intention to engage in a transaction involving a Change of Control, although it is possible that Aptiv would decide to do so in the future. Subject to the limitations discussed below, Aptiv could, in the future, enter into certain transactions, including acquisitions, refinancings or recapitalizations, that would not constitute a Change of Control under the Indenture, but that could increase the amount of Indebtedness outstanding at such time or otherwise affect Aptiv’s capital structure or credit ratings.

The occurrence of certain of the events which would constitute a Change of Control could constitute a default under the Credit Agreement. Future senior indebtedness of each of the Issuers and their respective subsidiaries may contain prohibitions of certain events which would constitute a Change of Control or require such senior indebtedness to be repurchased or repaid upon a Change of Control. Moreover, the exercise by the Holders of their right to require the Issuers to purchase the Notes could cause a default under the Credit Agreement or such other senior indebtedness, even if the Change of Control itself does not, due to the financial effect of such repurchase on the Issuers or restrictions contained in the Credit Agreement or the applicable agreements governing such other senior indebtedness. Finally, the Issuers’ ability to pay cash to the Holders upon a purchase may be limited by each of the Issuers’ then existing financial resources. There can be no assurance that sufficient funds will be available when necessary to make any required purchases.

The provisions under the Indenture relative to the Issuers’ respective obligations to make an offer to purchase the Notes as a result of a Change of Control Triggering Event may be waived or modified with the written consent of the Holders of a majority in principal amount of the Notes.

Tax Redemption

The Issuers may redeem the Notes as a whole but not in part, at their option at any time prior to maturity, upon the giving of a notice of redemption to the holders, if the Issuers determine that, as a result of:

which change or amendment is announced and becomes effective after the Issue Date (or, if the Relevant Jurisdiction becomes a Relevant Jurisdiction on a date after the Issue Date, after such later date) (each of the foregoing, a “Change in Tax Law”), each of the Issuers or the Guarantor is or will become obligated to pay Additional Amounts with respect to the Notes or the Note Guarantees on the next succeeding interest payment

S-22

date, as described below under “—Payment of Additional Amounts” (but in the case of the Guarantor, only if the payments giving rise to such obligation cannot be made by the Issuers or another Guarantor without the obligation to pay Additional Amounts) and the payment of such Additional Amounts cannot be avoided by the use of reasonable measures available to the Issuers or the Guarantor. The redemption price will be equal to 100% of the principal amount of the Notes plus accrued and unpaid interest to but excluding the date fixed for redemption (a “Tax Redemption Date”), and all Additional Amounts (if any) then due or which will become due on the Tax Redemption Date as a result of the redemption or otherwise (subject to the right of Holders of the Notes on any record date occurring prior to the Tax Redemption Date to receive interest due on the relevant interest payment date and Additional Amounts (if any) in respect thereof). The date and the applicable redemption price will be specified in the notice of tax redemption. Notice of such redemption will be irrevocable, and must be mailed by first-class mail to each Holder’s registered address, or delivered electronically if held by any depositary in accordance with such depositary’s customary procedures, not less than 15 nor more than 60 days prior to the earliest date on which we would be obligated to pay such Additional Amounts if a payment in respect of the Notes were actually due on such date. No such notice of redemption will be given unless, at the time such notification of redemption is given, such obligation to pay such Additional Amounts remains in effect.

Prior to giving the notice of tax redemption, we will deliver to the Trustee and the Paying Agent:

The foregoing provisions shall apply mutatis mutandis to any successor to the Issuers or the Guarantor.

Payment of Additional Amounts

Payments made by the Issuers, the Guarantor or a paying agent, as applicable, on the Notes or in respect of the Note Guarantee will be made free and clear of, and without withholding or deduction for or on account of, any present or future income, stamp or other tax, duty, levy, impost, assessment or other governmental charge of any nature whatsoever (“Taxes”), unless the Issuers, the Guarantor or a paying agent is required to withhold or deduct Taxes by law.

If any withholding or deduction for or on account of Taxes imposed or levied by or on behalf of Jersey, Ireland, any other jurisdiction in which the Issuers or the Guarantor is incorporated, organized, engaged in business or otherwise resident for tax purposes, or any other jurisdiction from or through which such payment is made, or in each case any political subdivision or taxing authority or agency thereof or therein (each, a “Relevant Jurisdiction”) is at any time required by law to be made from any payment made with respect to the Notes or the Note Guarantee, the Issuers, or the Guarantor, as applicable, will pay such additional amounts (“Additional Amounts”) on the Notes or in respect of the Note Guarantee as may be necessary so that the net amount received by each holder of the Notes (including Additional Amounts) after such withholding or deduction will not be less than the amount the holder would have received if such Taxes had not been withheld or deducted; provided that no Additional Amounts will be payable with respect to Taxes:

S-23

nor shall Additional Amounts be paid with respect to any payment of the principal of or interest, if any, on any Note or any payment in respect of the Note Guarantee to any such holder who is a fiduciary or a partnership that is not the sole beneficial owner of such payment to the extent a beneficiary or settlor with respect to such fiduciary or a member of such partnership or the beneficial owner would not have been entitled to such Additional Amounts had it been the holder of the Note.

The Issuers, the Guarantor or the paying agent, as applicable, will (i) make any required withholding or deduction, and (ii) remit the full amount deducted or withheld by it to the relevant jurisdiction in accordance with applicable law.

S-24

In addition, the Issuers shall pay any present or future stamp, issue, registration, court, documentary, excise, property, or similar Taxes (i) imposed by any Relevant Jurisdiction in respect of the execution, issuance, delivery, or registration of the Notes, the Note Guarantee, the Indenture, or any other document or instrument referred to therein, or the receipt of any payments with respect to the Notes, or (ii) imposed by any jurisdiction in respect of the enforcement of the Notes, the Note Guarantee, the Indenture, or any other document or instrument referred to therein.

The Issuers’ and the Guarantor’s respective obligations to pay Additional Amounts if and when due will survive the termination of the Indenture and the payment of all other amounts in respect of the Notes and shall apply mutatis mutandis to any successor of either of the Issuers or the Guarantor, and to any jurisdiction (other than the United States or any state thereof or the District of Columbia, or any political subdivision of any such state or the District of Columbia, or taxing authority or agency thereof or therein) in which such successor is incorporated, organized, engaged in business or otherwise resident for tax purposes, and any political subdivision or governmental authority thereof or therein.

Certain Covenants

The Indenture contains covenants including, among others, those summarized below.

Limitation on Liens

The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly, incur or permit to exist any Lien (the “Initial Lien”) of any nature whatsoever on any Principal Property (as defined below) or Capital Stock of a Restricted Subsidiary, whether owned at the Issue Date or thereafter acquired, which Initial Lien secures any Indebtedness, without effectively providing that the Notes shall be secured equally and ratably with (or prior to) the obligations so secured for so long as such obligations are so secured, other than the following (“Permitted Liens”):

S-25

S-26

“Principal Property” means any manufacturing or production plant located in the United States of America (including fixtures but excluding leases and other contract rights which might otherwise be deemed real property) owned by the Company or any Restricted Subsidiary, whether owned on the date hereof or thereafter, provided each such plant has a net book value at the date as of which the determination is being made of in excess of 1% of the Consolidated Total Assets of the Company and its Subsidiaries, other than any such plant which, in the opinion of the Board of Directors (evidenced by a certified board resolution thereof delivered to the Trustee), is not of material importance to the business conducted by the Company and its Subsidiaries taken as a whole. As of the Issue Date, neither the Company nor any Restricted Subsidiary owns any “Principal Property.” If the Company acquires property in the future that is “Principal Property,” it will be subject to this covenant.

Any Lien created for the benefit of the Holders of the Notes pursuant to the first paragraph of this covenant shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien.

For purposes of determining compliance with this covenant, (A) a Lien securing an item of Indebtedness need not be permitted solely by reference to one category of permitted Liens described in the definition of “Permitted Liens” but may be permitted in part under any combination thereof and (B) in the event that a Lien securing an item of Indebtedness (or any portion thereof) meets the criteria of one or more of the categories of permitted Liens described in the definition of “Permitted Liens,” the Company shall, in its sole discretion, classify or reclassify, or later divide, classify or reclassify, such Lien securing such item of Indebtedness (or any portion thereof) in any manner that complies with this covenant and will only be required to include the amount and type of such Lien or such item of Indebtedness secured by such Lien in one of the clauses of the definition of “Permitted Liens” and such Lien securing such item of Indebtedness will be treated as being incurred or existing pursuant to only one of such clauses.

Limitation on Sale and Leaseback Transactions

The Company will not, and will not permit any Restricted Subsidiary to, enter into any Sale and Leaseback Transaction with respect to any Principal Property unless:

S-27

Merger and Consolidation

Aptiv will not, directly or indirectly, consolidate with or merge with or into, or convey, transfer or lease all or substantially all its assets in one or a series of related transactions to, any Person, unless:

The Successor Company will succeed to, and be substituted for, and may exercise every right and power of, Aptiv under the Indenture, and the predecessor Issuers other than in the case of a lease, will be released from the obligation to pay the principal of and interest on the Notes.

In addition, the Co-Obligor will not, directly or indirectly, consolidate with or merge with or into any Person unless:

S-28

The Successor Co-Obligor will succeed to, and be substituted for, and may exercise every right and power of, the Co-Obligor under the Indenture, and the predecessor Co-Obligor will be released from the obligation to pay the principal of and interest on the Notes.

Notwithstanding the first paragraph above or the immediately preceding paragraph: (A) any Subsidiary of the Company may consolidate with, merge into or transfer all or part of its properties and assets to an Issuer, the Guarantor or any Subsidiary of the Company; and (B) the Issuers and the Guarantor may merge with an Affiliate organized solely for the purpose of reorganizing the Issuers or the Guarantor in another jurisdiction.

Defaults

Each of the following is an “Event of Default” with respect to the Notes:

The foregoing will constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body.

However, a default under clauses (4) or (5) will not constitute an Event of Default with respect to any Notes until the Trustee notifies the Issuers or the Holders of at least 25% in principal amount of the outstanding Notes and notes of all series affected thereby notify the Issuers and the Trustee of the default and the Issuers do not cure such default within the time specified in clauses (4) or (5) hereof after receipt of such notice.

If an Event of Default (other than an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Issuers) occurs and is continuing, the Trustee (at the direction of the Holders) or the Holders of at least 25% in principal amount of the outstanding Notes and all other notes issued under the Indenture affected thereby (all such series voting as a single class) by notice to the Issuers may declare the principal of and accrued but unpaid interest on all of the Notes and such other notes of the affected series to be

S-29

due and payable. Upon such a declaration, such principal and interest will be due and payable immediately. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of either of the Issuers occurs, the principal of and interest on all of the Notes will become immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. Under certain circumstances, the Holders of a majority in principal amount of the outstanding Notes and all other notes issued under the Indenture affected thereby (all such series voting as a single class) may rescind any such acceleration and its consequences.

Subject to the provisions of the Indenture relating to the duties of the Trustee, in case an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under the Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee security or indemnity satisfactory to it against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no Holder of a Note may pursue any remedy with respect to the Indenture or the Notes unless:

Subject to certain restrictions, the Holders of a majority in principal amount of the outstanding Notes and all other notes of all series affected thereby will be given the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee with respect to the Notes. However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder of a Note or that would involve the Trustee in personal liability. Prior to taking any action under the Indenture, the Trustee will be entitled to security or indemnification satisfactory to it in its sole discretion against all losses, liabilities and expenses.

If a Default occurs and is continuing and is actually known to the Trustee with respect to the Notes, the Trustee must deliver to each Holder of the Notes, notice of the Default within 30 days after it is actually known to a Trust Officer or written notice of it is received by the Trustee. Except in the case of a Default in the payment of principal of, premium (if any) or interest on any Note (including payments pursuant to the redemption provisions of such Note), the Trustee may withhold notice if and so long as a committee of its Trust Officers in good faith determines that withholding notice is in the interests of the Holders. In addition, the Issuers will be required to deliver to the Trustee, within 120 days after the end of each fiscal year, a certificate indicating whether the signers thereof know of any Default that occurred during the previous year. The Issuers will also be required to deliver to the Trustee, Registrar and Paying Agent, within 30 days after the occurrence thereof, written notice of any event which would constitute certain Events of Default, their status and what action the Issuers are taking or proposes to take in respect thereof.

Amendments and Waivers

Subject to certain exceptions, the Indenture or the Notes may be amended as it relates to the Notes with the written consent of the Holders of a majority in principal amount of the Notes then outstanding and all other notes issued under the Indenture affected thereby (all such series voting as a single class) and any past default or

S-30

compliance with any provisions with respect to the Notes may be waived with the consent of the Holders of a majority in principal amount of the Notes then outstanding and all other notes of all series affected thereby voting as a single class. However, without the consent of each Holder of an outstanding Note affected, no amendment may, among other things:

Notwithstanding anything herein or otherwise, the provisions under the Indenture relative to the Issuers’ respective obligations to make any offer to repurchase the Notes as a result of a Change of Control Triggering Event as described under the heading “—Change of Control Triggering Event” above may be waived or modified with the written consent of the Holders of a majority in principal amount of the Notes.

Without the consent of any Holder of the Notes, the Issuers and the Trustee, as applicable, may amend the Indenture and the Notes to:

S-31

The consent of the Holders will not be necessary to approve the particular form of any proposed amendment or waiver. It will be sufficient if such consent approves the substance of the proposed amendment or waiver.

An amendment that changes or eliminates any covenant or event of default set forth in the Indenture or other provision of the Indenture that has been expressly included solely for the benefit of one or more particular series of debt securities, if any, or which modifies the rights of the holders of debt securities of such series with respect to such covenant, event of default or other provision, shall be deemed not to affect the rights under the Indenture of the holders of debt securities of any other series.

After an amendment becomes effective, the Issuers are required to deliver to Holders a notice briefly describing such amendment. However, the failure to give such notice to all Holders, or any defect therein, will not impair or affect the validity of the amendment.

Transfer and Exchange

A Holder will be able to transfer or exchange Notes in accordance with the restrictions set forth in the Indenture. Upon any transfer or exchange, the Registrar, Paying Agent and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuers may require Holders to pay any transfer tax or other similar governmental charge payable in connection with any such transfer or exchange that are required by law or permitted by the Indenture. The Issuers will not be required to transfer or exchange any Note selected for redemption or to transfer or exchange any Note for a period of 15 days prior to a selection of Notes to be redeemed. The Notes will be issued in registered form and the Holder will be treated as the owner of such Note for all purposes.

Satisfaction and Discharge

When (1) the Issuers deliver to the Registrar and Paying Agent all outstanding Notes for cancellation or (2) all outstanding Notes have become due and payable or will become due and payable within one year, whether at maturity or on a redemption date as a result of the delivery by the Issuers of a notice of irrevocable redemption to the Trustee, Registrar and Paying Agent and, in the case of clause (2), the Issuers deposit with the Registrar and Paying Agent funds or Government Obligations sufficient to pay at maturity or upon redemption all outstanding Notes, including premium, if any, interest thereon to maturity or such redemption date, and if in any case the Issuers pay all other sums payable under the Indenture by the Issuers with respect to the Notes, then the Indenture shall, subject to certain exceptions, cease to be of further effect with respect to all outstanding Notes; provided that in a discharge in connection with any redemption that requires the payment of a premium based on the Comparable Government Bond Rate plus a specified amount of basis points (the “Applicable Premium”), the amount deposited shall be sufficient for purposes of the Indenture to the extent that an amount is deposited with the Paying Agent equal to the Applicable Premium with respect to such Notes calculated as of the date of the notice of redemption, with any deficit on the date of redemption (the “Applicable Premium Deficit”) only required to be deposited with the Paying Agent on or prior to the date of the redemption. Any Applicable Premium Deficit shall be set forth in an Officer’s Certificate delivered to the Paying Agent with a copy to the Trustee simultaneously with the deposit of such Applicable Premium Deficit that confirms that such Applicable Premium Deficit shall be applied toward such redemption.

Defeasance

The Issuers may, as described below, at any time terminate all their and the Guarantor’s respective obligations under the Indenture with respect to the Notes (“legal defeasance”), except for certain obligations,

S-32

including those respecting the defeasance trust and obligations to register the transfer or exchange of the Notes, to replace mutilated, destroyed, lost or stolen Notes and to maintain a Registrar and Paying Agent in respect of the Notes.

In addition, the Issuers may, as described below, at any time terminate in respect of the Notes:

In the event that the Issuers exercise their legal defeasance option or their covenant defeasance option with respect to the Notes, the Guarantor will be released from all of its obligations with respect to its Note Guarantee in respect of such Notes.

The Issuers may exercise their legal defeasance option notwithstanding its prior exercise of their covenant defeasance option. If the Issuers exercise their legal defeasance option with respect to the Notes, payment of the Notes may not be accelerated because of an Event of Default with respect thereto. If the Issuers exercise their covenant defeasance option with respect to the Notes, payment of the Notes may not be accelerated because of an Event of Default specified in, or resulting from a breach of, the defeased provisions.

In order to exercise either defeasance option with respect to the Notes, the Issuers must deposit in trust (the “defeasance trust”) with the Paying Agent money in an amount sufficient or Government Obligations, the principal of and interest on which will be sufficient, or a combination thereof sufficient, without consideration of any reinvestment of such principal and interest, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Paying Agent, to pay the principal of, premium (if any) and interest in respect of the Notes to redemption or maturity, as the case may be, and must comply with certain other conditions, including delivery to the Paying Agent with a copy to the Trustee of an Opinion of Counsel to the effect that beneficial owners of Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such deposit and defeasance and will be subject to U.S. federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred (and, in the case of legal defeasance only, such Opinion of Counsel must be based on a ruling of the Internal Revenue Service or other change in applicable U.S. federal income tax law).

Book-Entry, Delivery and Form

We have obtained the information in this section concerning Clearstream Banking, société anonyme (“Clearstream”), and Euroclear Bank S.A./N.V. (“Euroclear”) and their book-entry systems and procedures from sources that we believe to be reliable. We take no responsibility for an accurate portrayal of this information. In addition, the description of the clearing systems in this section reflects our understanding of the rules and procedures of Clearstream and Euroclear as they are currently in effect. Those clearing systems could change their rules and procedures at any time.

The Notes will initially be represented by one or more fully registered global notes. Each such global note will be deposited with, or on behalf of, a common depositary, and registered in the name of the nominee of the common depositary for the accounts of Clearstream and Euroclear. Except as set forth below, the global notes may be transferred, in whole and not in part, only to Clearstream or Euroclear or their respective nominees. You may hold your interests in the global notes in Europe through Clearstream or Euroclear, either as a participant in such systems or indirectly through organizations which are participants in such systems. Clearstream and Euroclear will hold interests in the global notes on behalf of their respective participating organizations or

S-33

customers through customers’ securities accounts in Clearstream’s or Euroclear’s names on the books of their respective depositories. Book-entry interests in the Notes and all transfers relating to the Notes will be reflected in the book-entry records of Clearstream and Euroclear. The address of Clearstream is 42 Avenue JF Kennedy, L-1855 Luxembourg, Luxembourg and the address of Euroclear is 1 Boulevard du Roi Albert II, B-1210 Brussels, Belgium.

The distribution of the Notes will be cleared through Clearstream and Euroclear. Any secondary market trading of book-entry interests in the Notes will take place through Clearstream and Euroclear participants and will settle in same-day funds. Owners of book-entry interests in the Notes will receive payments relating to their Notes in euro, except as described in this prospectus supplement under “—Issuance in Euro; Currency Conversion.”

Clearstream and Euroclear have established electronic securities and payment transfer, processing, depository and custodial links among themselves and others, either directly or through custodians and depositories. These links allow the Notes to be issued, held and transferred among the clearing systems without the physical transfer of certificates. Special procedures to facilitate clearance and settlement have been established among these clearing systems to trade securities across borders in the secondary market.

The policies of Clearstream and Euroclear will govern payments, transfers, exchanges and other matters relating to the investor’s interest in the Notes held by them. We have no responsibility for any aspect of the records kept by Clearstream or Euroclear or any of their direct or indirect participants. We also do not supervise these systems in any way.

Clearstream and Euroclear and their participants perform these clearance and settlement functions under agreements they have made with one another or with their customers. You should be aware that they are not obligated to perform or continue to perform these procedures and may modify them or discontinue them at any time.

Except as provided below, owners of beneficial interests in the Notes will not be entitled to have the Notes registered in their names, will not receive or be entitled to receive physical delivery of the Notes in definitive form and will not be considered the owners or holders of the Notes under the indenture. Accordingly, each person owning a beneficial interest in the Notes must rely on the procedures of the depository, and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, in order to exercise any rights of a holder of Notes.

We have been advised by Clearstream and Euroclear, respectively, as follows:

Clearstream. Clearstream is incorporated under the laws of Luxembourg as a professional depository. Clearstream holds securities for its participating organizations (“Clearstream Participants”) and facilitates the clearance and settlement of securities transactions between Clearstream Participants through electronic book-entry changes in accounts of Clearstream Participants, thereby eliminating the need for physical movement of certificates. Clearstream provides Clearstream Participants with, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries. As a professional depository, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission de Surveillance du Secteur Financier). Clearstream Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, and may include the underwriters. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Participant either directly or indirectly.

Distributions with respect to interests in the Notes held beneficially through Clearstream will be credited to cash accounts of Clearstream Participants in accordance with its rules and procedures.

S-34

Euroclear. Euroclear was created in 1968 to hold securities for participants of Euroclear (“Euroclear Participants”) and to clear and settle transactions between Euroclear Participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear includes various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A./N.V. (the “Euroclear Operator”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator. Euroclear Participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

The Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, or the Euroclear Terms and Conditions, and applicable Belgian law govern securities clearance accounts and cash accounts with the Euroclear Operator. Specifically, these terms and conditions govern:

All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the terms and conditions only on behalf of Euroclear Participants and has no record of or relationship with persons holding securities through Euroclear Participants. Distributions with respect to interests in the Notes held beneficially through Euroclear will be credited to the cash accounts of Euroclear Participants in accordance with the Euroclear Terms and Conditions.

Clearance and Settlement Procedures. We understand that investors that hold their Notes through Clearstream or Euroclear accounts will follow the settlement procedures that are applicable to conventional eurobonds in registered form. Notes will be credited to the securities custody accounts of Clearstream and Euroclear participants on the business day following the settlement date against payment for value on the settlement date.

We understand that secondary market trading between Clearstream and/or Euroclear participants will occur in the ordinary way following the applicable rules and operating procedures of Clearstream and Euroclear. Secondary market trading will be settled using procedures applicable to conventional eurobonds in registered form.

You should be aware that investors will only be able to make and receive deliveries, payments and other communications involving the Notes through Clearstream and Euroclear on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States.

In addition, because of time-zone differences, there may be problems with completing transactions involving Clearstream and Euroclear on the same business day as in the United States. U.S. investors who wish to transfer their interests in the Notes, or to make or receive a payment or delivery of the Notes, on a particular day, may find that the transactions will not be performed until the next business day in Luxembourg or Brussels, depending on whether Clearstream or Euroclear is used.

Clearstream or Euroclear will credit payments to the cash accounts of Clearstream customers or Euroclear participants, as applicable, in accordance with the relevant system’s rules and procedures, to the extent received

S-35

by its depository. Clearstream or the Euroclear Operator, as the case may be, will take any other action permitted to be taken by a holder under the indenture on behalf of a Clearstream customer or Euroclear participant only in accordance with its relevant rules and procedures.

Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of the Notes among participants of Clearstream and Euroclear. However, they are under no obligation to perform or continue to perform those procedures, and they may discontinue those procedures at any time.

Certificated Notes

Subject to certain conditions, the Notes represented by the global notes are exchangeable for certificated notes in definitive form of like tenor in minimum denominations of €100,000 principal amount and integral multiples of €1,000 in excess thereof if:

Any note of that is exchangeable as above is exchangeable for certificated notes issuable in authorized denominations and registered in such names as the common depositary shall direct. Subject to the foregoing, a global note is not exchangeable, except for a global note of the same aggregate denomination to be registered in the name of the common depositary (or its nominee).

Concerning the Trustee and the Registrar and Paying Agent

Wilmington Trust, National Association is the Trustee under the Indenture and Deutsche Bank Trust Company Americas (“DBTCA”) has been appointed by the Issuers as Registrar and Paying Agent with regard to the Notes. The Trustee and its affiliates have engaged and may in the future engage in financial or other transactions with the Issuers, the Guarantor and their respective affiliates in the ordinary course of their respective businesses, subject to the TIA.

The Registrar and Paying Agent have engaged, currently are engaged, and may in the future engage in financial or other transactions with the Issuers, the Guarantor and their respective affiliates in the ordinary course of their respective businesses.

TAX CONSIDERATIONS

The information presented under the caption “Jersey Tax Considerations” below is a discussion of the material Jersey tax consequences of investing in the Notes. The information presented under the caption “Irish Tax Considerations” below is a discussion of Aptiv PLC’s status as a resident of Ireland for Irish tax purposes and of the material Irish tax consequences of investing in the Notes. The information presented under the caption “U.S. Federal Income Tax Considerations” below is a discussion of the material U.S. federal income tax consequences to U.S. Holders (as defined below) of investing in the Notes.

You should consult your tax adviser regarding the applicable tax consequences to you of investing in the Notes under the laws of Ireland, Jersey and the United States (federal, state and local) and any other applicable foreign jurisdiction.

Irish Tax Considerations

The following is a summary of the principal Irish withholding tax consequences for individuals and companies of ownership of the Notes, and some other miscellaneous tax matters, based on the laws and practice of the Irish Revenue Commissioners currently in force in Ireland and may be subject to change. It deals with Holders who beneficially own their Notes as an investment and who are not associated with the Issuer (otherwise than by virtue of holding the notes). Particular rules not discussed below may apply to certain classes of taxpayers holding Notes, such as dealers in securities, trusts, etc. The summary does not constitute tax or legal advice and the comments below are of a general nature only. Prospective investors in the Notes should consult their professional advisers on the tax implications of the purchase, holding, redemption or sale of the Notes and the receipt of interest thereon under the laws of their country of residence, citizenship or domicile.

Taxation of Holders

Withholding Tax

In general, tax at the standard rate of income tax (currently 20%) is required to be withheld from payments of Irish-source interest, which may include interest payable on the Notes.

The Issuers will not be obliged to make a withholding or deduction for or on account of Irish income tax from a payment of interest on a Note so long as interest paid on the relevant Note falls within one of the following categories:

Thus, so long as the Notes continue to be quoted on the NYSE and are held in DTC, Euroclear and/or Clearstream, interest on the Notes can be paid by any paying agent acting on behalf of the Issuers free of any withholding or deduction for or on account of Irish income tax. If the Notes continue to be quoted but cease to be held in a recognised clearing system, interest on the Notes may be paid without any withholding or deduction for or on account of Irish income tax, provided such payment is made through a paying agent outside Ireland.

S-42

Encashment Tax

Irish tax will be required to be withheld at a rate of 25% from interest on any Note, where such interest is collected or realised by a bank or encashment agent in Ireland on behalf of any Holder. There is an exemption from encashment tax where (i) the beneficial owner of the interest is not resident in Ireland and has made a declaration to this effect in the prescribed form to the encashment agent or bank or (ii) the beneficial owner of the interest is a company which is within the charge to Irish corporation tax in respect of the interest.

Stamp Duty

No stamp duty, capital duty or similar tax is imposed in Ireland on the issue of the Notes. Furthermore, no stamp duty is imposed in Ireland on the transfer of the Notes within DTC, Euroclear or Clearstream.

Jersey Tax Considerations

The following summary of the anticipated treatment of Aptiv and holders of Notes (other than residents of Jersey) is based on Jersey taxation law and practice as they are understood to apply at the date of this document and is subject to changes in such taxation law and practice. It does not constitute legal or tax advice and does not address all aspects of Jersey tax law and practice. Prospective investors in the Notes should consult their professional advisers on the implications of acquiring, buying, selling or otherwise disposing of the Notes under the laws of any jurisdiction in which they may be liable to taxation.

Taxation of Aptiv

Aptiv is not regarded as a resident for tax purposes in Jersey. Therefore, Aptiv will not be liable to Jersey income tax other than on Jersey source income (except where such income is exempted from income tax pursuant to the Income Tax (Jersey) Law 1961, as amended) and payments in respect of the Notes may be paid by Aptiv without withholding or deduction for or on account of Jersey income tax. The holders of Notes (other than residents of Jersey) will not be subject to any tax in Jersey in respect of the holding, sale or other disposition of such Notes.

Stamp Duty

In Jersey, no stamp duty is levied on the issue or transfer of the Notes except that stamp duty is payable on Jersey grants of probate and letters of administration, which will generally be required to transfer the Notes on the death of a holder of such Notes where such Notes are situated in Jersey. In the case of a grant of probate or letters of administration, stamp duty is levied according to the size of the estate (wherever situated in respect of a holder of Notes domiciled in Jersey, or situated in Jersey in respect of a holder of Notes domiciled outside Jersey) and is payable on a sliding scale at a rate of up to 0.75% of such estate and such duty is capped at £100,000. Where the Notes are in registered form and the register is not maintained in Jersey, such Notes should not be considered to be situated in Jersey for these purposes.

Jersey does not otherwise levy taxes upon capital, inheritances, capital gains or gifts nor are there other estate duties.

If you are in any doubt as to your tax position you should consult your professional tax adviser.

U.S. Federal Income Tax Considerations

The following summary describes material U.S. federal income tax consequences of ownership and disposition of the Notes to U.S. Holders, as defined below. This discussion applies only if you:

S-43

This discussion does not describe all of the tax consequences that may be relevant to you in light of your particular circumstances or if you are in a category of persons that are subject to special rules, such as:

If you are a partner in an entity that is classified as a partnership for U.S. federal income tax purposes and that holds Notes, your U.S. federal income tax treatment with respect to the Notes will generally depend on your status and upon the activities of the partnership. You and the partnership should each consult your own tax advisor as to the particular U.S. federal income tax consequences of owning and disposing of the Notes.

This summary is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury Regulations, changes to any of which subsequent to the date of this prospectus supplement may affect the tax consequences described herein (possibly with retroactive effect). You should consult your own tax advisor with regard to the application of the U.S. federal income tax laws (including the unearned income Medicare contribution tax under Section 1411 of the Code) to your particular situation as well as any tax consequences arising under other U.S. federal tax laws (such as estate and gift tax laws) or the laws of any state, local or non-U.S. taxing jurisdiction.

As used herein, the term “U.S. Holder” means a beneficial owner of a Note that is, for U.S. federal income tax purposes:

S-44

Possible Application of Rules Governing Contingent Payment Debt Instruments

Under certain circumstances, including as described under “Description of the Notes—Change of Control Triggering Event” and “Description of the Notes—Additional Amounts,” payments on the Notes may be made at times and/or in amounts that differ from the times and amounts which are otherwise required under the Notes. We intend to take the position that the possibility of such payments does not result in the Notes being treated as contingent payment debt instruments under the applicable Treasury Regulations. Our position is binding on you unless you disclose that you are taking a contrary position in the manner required by applicable Treasury Regulations. Our position is not, however, binding on the IRS, and if the IRS were to challenge this position, you might be required to use the accrual method, even if you were otherwise a cash method taxpayer, to accrue income on a Note in excess of the stated interest on the Note and to treat as ordinary income rather than capital gain any income that you recognize on the taxable disposition of the Note. The remainder of this discussion assumes that the Notes will not be considered contingent payment debt instruments.

Effect of Co-Issuance

On the Issue Date, all or a portion of the proceeds of the offering of the Notes will be borrowed by Aptiv Global Financing Limited and the remaining portion of the proceeds of the offering of the Notes will be borrowed by Aptiv. The portion of the proceeds of the Notes that will be borrowed by Aptiv Global Financing Limited and the portion of the proceeds of the Notes that will be borrowed by Aptiv, if any, in each case, on the Issue Date, and after any subsequent change to such allocation (as discussed below), will be made available to a holder or beneficial owner of the Notes upon request by contacting Aptiv Investor Relations (which can be reached through Aptiv’s website or at ir@aptiv.com).

Aptiv Global Financing Limited and Aptiv have the right to change the allocation of the Notes between Aptiv Global Financing Limited and Aptiv for any reason (including, but not limited, as a result of a redemption of any Notes or the issuance of Additional Notes, in each case, in a different allocation between Aptiv Global Financing Limited and Aptiv than the initial allocation with respect to the outstanding Notes). Aptiv Global Financing Limited and Aptiv may issue Additional Notes that have a different allocation than the initial allocation with respect to the outstanding Notes. In such event, we intend to take the position that, while not entirely clear, such Additional Notes are fungible with the outstanding Notes for U.S. federal income tax purposes, resulting in a change in the allocation of the outstanding Notes so as to have the same allocation across the Additional Notes and the outstanding Notes. While we also intend to take the position that any such transaction will not result in a taxable event for U.S. federal income tax purposes, there can be no assurance that the IRS or a court will agree with our position, in which case beneficial owners may recognize gain, but potentially not loss, in such transaction.

You should consult your own tax advisor as to the treatment of the Notes (including any related U.S. federal income tax consequences).

Stated Interest

Stated interest paid on a Note (including any amounts withheld and any Additional Amounts paid in respect of withholding taxes imposed on payments on the Note) will be taxable to a U.S. Holder as ordinary interest income at the time it accrues or is received in accordance with the U.S. Holder’s method of accounting for U.S. federal income tax purposes. It is expected and this discussion assumes that the Notes will be issued without original issue discount for U.S. federal income tax purposes.

U.S. Holders that use the cash method of accounting for U.S. federal income tax purposes will be required to include in income the U.S. dollar value of a euro interest payment determined based on the spot rate on the date the payment is received, regardless of whether the payment is in fact converted into U.S. dollars. Such U.S. Holders generally will not recognize foreign currency exchange gain or loss with respect to the receipt of interest payments. U.S. Holders that use the accrual method of accounting for U.S. federal income tax purposes will accrue interest income on the Notes in euro and translate that amount into U.S. dollars at the average rate of

S-45

exchange for the accrual period (or, with respect to an accrual period that spans two taxable years, at the average rate of exchange for the partial period within the taxable year). Alternatively, an accrual-method U.S. Holder may elect to translate accrued interest income into U.S. dollars at the spot rate in effect on the last day of the accrual period (or the last day of the taxable year, in the case of a partial accrual period) or at the spot rate on the date the payment is received, if that date is within five business days of the last day of the accrual period. This election must be applied consistently to all debt instruments from year to year and cannot be changed without the consent of the IRS. Accrual-method U.S. Holders will recognize foreign currency exchange gain or loss in an amount equal to the difference between the U.S. dollar value of a euro interest payment received in respect of an accrual period (determined based on the spot rate on the date the payment is received) and the U.S. dollar value of interest income that has accrued during the accrual period (as described above), regardless of whether the payment is in fact converted into U.S. dollars. Any foreign currency exchange gain or loss will generally be treated as U.S.-source ordinary income or loss.

Foreign Tax Credit

Interest paid on a Note generally will be foreign-source “passive category income” for purposes of computing the foreign tax credit allowable to a U.S. Holder under U.S. federal income tax law. Non-U.S. withholding taxes, if any, paid by or on behalf of a U.S. Holder at the rate applicable to such U.S. Holder may be eligible for foreign tax credits (or, at such U.S. Holder’s election, deductions in lieu of such credits) for U.S. federal income tax purposes, subject to applicable limitations and conditions (including that the election to deduct or credit non-U.S. taxes applies to all of the U.S. Holder’s applicable non-U.S. taxes for a particular tax year). Applicable U.S. Treasury regulations may restrict the availability of any foreign tax credit based on the nature of the withholding tax imposed by a non-U.S. jurisdiction. The calculation of foreign tax credits involves the application of complex rules that depend on a U.S. Holder’s particular circumstances. A U.S. Holder should consult its own tax advisor regarding the creditability or deductibility of any non-U.S. withholding taxes.

Sale, Exchange, Redemption or Retirement

Upon the sale, exchange, redemption, retirement or other taxable disposition of a Note, a U.S. Holder will generally recognize taxable gain or loss equal to the difference between the amount realized on the sale, exchange, redemption, retirement or other taxable disposition of the Note and the U.S. Holder’s tax basis in the Note. A U.S. Holder’s tax basis in a Note will generally be the U.S. dollar value of the euro amount paid for the Note, generally determined on the date of the purchase. However, if the Notes are traded on an established securities market, and the U.S. Holder is a cash-method taxpayer (or an accrual-method taxpayer that so elects), the U.S. Holder will determine the U.S. dollar value of the euro amount paid for the Note at the spot rate on the settlement date of the purchase. An accrual-method U.S. Holder that makes this election must apply it consistently to all debt instruments from year to year and cannot change the election without the consent of the IRS. If a Note is sold, exchanged or otherwise disposed of in a taxable transaction for an amount denominated in euro, a U.S. Holder’s amount realized generally will equal the U.S. dollar value of the euro received in the sale, exchange or other taxable disposition, generally calculated at the spot rate in effect on the date of the disposition (or the settlement date of the disposition if the Notes are traded on an established securities market and the U.S. Holder is a cash method taxpayer or an electing accrual method taxpayer, as described above). Except to the extent of foreign currency gain or loss (as described below), gain or loss recognized on the sale, exchange, redemption, retirement or other taxable disposition of a Note will generally be capital gain or loss and will be long-term capital gain or loss if at the time of sale, exchange, redemption, retirement or other taxable disposition the Note has been held for more than one year. Long-term capital gains recognized by non-corporate U.S. Holders are subject to reduced tax rates. The deductibility of capital losses may be subject to limitations.

A U.S. Holder may recognize foreign currency gain or loss upon the sale, exchange, redemption, retirement or other taxable disposition of a Note as a result of fluctuations in the euro-U.S. dollar exchange rate. Gain or loss attributable to such fluctuations will equal the difference between (i) the U.S. dollar value of the U.S. Holder’s purchase price in euro of the Note, determined using the spot rate on the date the Note is disposed of

S-46

(or, possibly, in the case of cash method or electing accrual method taxpayers, the settlement date of such disposition, if the Note is treated as traded on an established securities market), and (ii) the U.S. dollar value of the U.S. Holder’s purchase price in euro of the Note, determined using the spot rate on the date the U.S. Holder acquired the Note. The foreign currency gain or loss will be recognized only to the extent of the total gain or loss recognized by a U.S. Holder on the sale, exchange, redemption, retirement or other taxable disposition of the Note. Any such gain or loss generally will be ordinary income or loss and generally will constitute U.S.-source income. If a U.S. Holder recognizes a loss upon a sale, exchange, redemption, retirement or other taxable disposition of a Note and such loss is above certain thresholds (which thresholds are, in the case of individuals and trusts, significantly lower for foreign currency losses than for other loss transactions), the U.S. Holder may be required to file a disclosure statement with the IRS. U.S. Holders should consult their own tax advisors regarding this reporting obligation and the significant penalties for non-compliance.

Foreign Financial Asset Reporting

Certain U.S. Holders may be required to report information relating to an interest in “specified foreign financial assets,” subject to certain exceptions (including an exception for specified foreign financial assets held in accounts maintained by financial institutions), by attaching a complete IRS Form 8938, Statement of Specified Foreign Financial Assets, to their tax return for each year in which they hold an interest in such specified foreign financial assets. If a U.S. Holder does not file a required IRS Form 8938, such holder may be subject to substantial penalties and the statute of limitations on the assessment and collection of all U.S. federal income taxes of such holder for the related tax year may not close before the date which is three years after the date on which such report is filed. U.S. Holders should consult their own tax advisors regarding information reporting requirements relating to their ownership of the Notes, including the significant penalties for non-compliance.

Backup Withholding and Information Reporting

Information returns will be filed with the IRS in connection with stated interest payments on the Notes to, and the proceeds from a sale or other disposition (including a retirement or redemption) of the Notes by, a U.S. Holder unless the U.S. Holder is an exempt recipient. A U.S. Holder will be subject to U.S. backup withholding on payments of these amounts if the U.S. Holder fails to provide the U.S. Holder’s taxpayer identification number to the appropriate withholding agent and complies with certain certification procedures, or otherwise fails to establish an exemption from backup withholding. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the U.S. Holder’s U.S. federal income tax liability and may entitle the U.S. Holder to a refund, if the U.S. Holder timely provides the required information to the IRS.

S-47

UNDERWRITING

Subject to the terms and conditions of the underwriting agreement dated the date of this prospectus supplement, the underwriters named below have severally, and not jointly, agreed to purchase from the Issuers, and the Issuers have agreed to sell to the underwriters, the principal amount of Notes listed opposite their names below at the public offering price less the underwriting discount set forth on the cover page of this prospectus supplement:

The underwriting agreement provides that the obligations of the several underwriters to purchase the Notes offered hereby are subject to certain conditions and that the underwriters will purchase all of the Notes offered by this prospectus supplement if any of the Notes are purchased. The underwriting agreement also provides that if an underwriter defaults with respect to the Notes, the purchase commitments of non-defaulting underwriters may be increased or the offering of the Notes may be terminated under certain conditions.

The Issuers have been advised by the underwriters that the underwriters propose to offer the Notes directly to the public at the public offering price set forth on the cover page of this prospectus supplement. After the initial public offering, the underwriters may change the offering price and other selling terms. The underwriters may offer and sell Notes through certain of their affiliates. The offering of the Notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

The following table shows the underwriting discounts that the Issuers are to pay to the underwriters in connection with this offering (expressed as a percentage of the principal amount of the Notes and in total):

The Issuers estimate that their expenses of this offering, excluding the underwriting discounts, will be approximately €     million.

In the underwriting agreement, the Issuers have agreed that they will indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act, or contribute to payments the underwriters may be required to make in respect of any of these liabilities.

The Issuers intend to apply to list the Notes on the NYSE. If such listings are obtained, the Issuers will have no obligation to maintain such listings, and the Issuers may delist the Notes at any time. There is currently no established trading market for the Notes. The underwriters have advised the Issuers that they currently intend to make a market in the Notes. However, they are not obligated to do so, and they may discontinue any market-making with respect to the Notes without notice. Accordingly, the Issuers cannot assure you as to the development or liquidity of any market for the Notes.

In connection with this offering of the Notes, the underwriters may engage in overallotments, stabilizing transactions and syndicate covering transactions. Overallotment involves sales in excess of the aggregate principal amount of Notes offered pursuant to this prospectus, which creates a short position for the underwriters.

S-48

Stabilizing transactions involve bids to purchase the Notes in the open market for the purpose of pegging, fixing or maintaining the price of the Notes. Syndicate covering transactions involve purchases of the Notes in the open market after the distribution has been completed in order to cover short positions. Any of these activities may cause the market prices of the Notes to be higher than they would otherwise be in the absence of those transactions. The underwriters are not required to engage in any of these activities, and may end any of them at any time.

The Issuers expect that the delivery of the Notes will be made against payment therefor on or about     , 2024, which will be the      day following the date of pricing of the notes (such settlement cycle being herein referred to as “T+ ”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes prior to the date that is more than one business day preceding the settlement date will be required, by virtue of the fact that the Notes initially will settle T+ , to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of Notes who wish to trade Notes prior to the date that is more than one business day preceding the settlement date should consult their own advisor.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. The underwriters and their respective affiliates have from time to time provided, and may provide in the future, various financial advisory, investment banking and commercial banking services to us and our affiliates, for which they have received or will receive customary fees and reimbursement of expenses. In particular, certain of the underwriters and/or their respective affiliates are parties to and are agents and/or lenders under our credit facility and receive customary compensation in connection therewith. The credit facility was negotiated on an arm’s length basis and contains terms pursuant to which the lenders receive customary fees. The underwriters and/or their respective affiliates may hold notes issued by either of the Issuers and, as a result, may receive a portion of the net proceeds from this offering.

In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments, including serving as counterparties to certain derivative and hedging arrangements, and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments of the Company. The underwriters and their respective affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

If any of the underwriters or their respective affiliates have a lending relationship with us, certain of those underwriters or their respective affiliates routinely hedge, and certain other of those underwriters or their respective affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the Notes offered hereby.

Under this shelf process, we may sell the securities or any combination of the securities described in this prospectus, and the selling shareholders may sell our ordinary shares, in one or more offerings. This prospectus provides you with a general description of the securities we and the selling shareholders may offer. Each time we sell securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering and, as the case may be, the identity of the selling shareholders. The prospectus supplement may also add, update or change information contained in this prospectus. You should read both this prospectus and any prospectus supplement together with additional information described under the heading “Where You Can Find More Information.”

SPECIAL NOTE ON FORWARD-LOOKING STATEMENTS

This prospectus, including the documents incorporated by reference herein, contains forward-looking statements that reflect, when made, our current views with respect to current events and financial performance including the potential impact of the proposed acquisition of Wind River Systems, Inc. Such forward-looking statements are subject to many risks, uncertainties and factors relating to our operations and business environment, which may cause our actual results to be materially different from any future results, express or implied, by such forward-looking statements. All statements that address future operating, financial or business performance or our strategies or expectations are forward-looking statements. In some cases, you can identify these statements by forward-looking words such as “may,” “might,” “will,” “should,” “expects,” “plans,” “intends,” “anticipates,” “believes,” “estimates,” “predicts,” “projects,” “potential,” “outlook” or “continue,” and other comparable terminology. Factors that could cause actual results to differ materially from these forward-looking statements include, but are not limited to, the following: global and regional economic conditions, including conditions affecting the credit market; uncertainties posed by the COVID-19 pandemic and the difficulty in predicting its future course and its impact on the global economy and our future operations; fluctuations in interest rates and foreign currency exchange rates; the cyclical nature of global automotive sales and production; the potential disruptions in the supply of and changes in the competitive environment for raw material and other components integral to our products, including the current semiconductor supply shortage; our ability to maintain contracts that are critical to our operations; potential changes to beneficial free trade laws and regulations, such as the United States-Mexico-Canada Agreement; our ability to integrate and realize the expected benefits of recent transactions; our ability to attract, motivate and/or retain key executives; our ability to avoid or continue to operate during a strike, or partial work stoppage or slow down by any of our unionized employees or those of our principal customers; and our ability to attract and retain customers. Additional factors are discussed under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our filings with the Securities and Exchange Commission, including those set forth in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021. New risks and uncertainties arise from time to time, and it is impossible for us to predict these events or how they may affect us. It should be remembered that the price of the ordinary shares and any income from them can go down as well as up. We disclaim any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events and/or otherwise, except as may be required by law.

5

Although we believe the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, level of activity, performance or achievements. Moreover, neither we nor any other person assumes responsibility for the accuracy and completeness of any of these forward-looking statements. We are under no duty to update any of these forward-looking statements after the date of this prospectus to conform our prior statements to actual results or revised expectations.

RISK FACTORS

Before making an investment decision, you should carefully consider the risks described under “Risk Factors” in the applicable prospectus supplement and in our then most recent Annual Report on Form 10-K, and in any updates to those risk factors in our Quarterly Reports on Form 10-Q, together with all of the other information appearing or incorporated by reference in this prospectus and any applicable prospectus supplement, in light of your particular investment objectives and financial circumstances.

USE OF PROCEEDS

Unless otherwise indicated in a prospectus supplement, the net proceeds from the sale of the securities will be used for general corporate purposes, including working capital, acquisitions, retirement of debt and other business opportunities. In the case of a sale by a selling shareholder, we will not receive any of the proceeds from such sale.

DESCRIPTION OF SHARE CAPITAL

The following descriptions are summaries of the material terms of our Articles of Association and Memorandum of Association (as amended, our “Articles of Association” and “Memorandum of Association,” respectively). Reference is made to the more detailed provisions of, and the descriptions are qualified in their entirety by reference to, the Articles of Association and Memorandum of Association, which are incorporated by reference as an exhibit to the registration statement of which this prospectus is a part, and applicable law.

Ordinary Shares

As of January 28, 2022, there were 270,514,140 ordinary shares issued and outstanding. All outstanding ordinary shares are validly issued, fully paid and non-assessable. The ordinary shares do not have preemptive, subscription or redemption rights. Neither our Memorandum of Association or Articles of Association nor the laws of Jersey restrict in any way the ownership or voting of ordinary shares held by non-residents of Jersey.

Our Board may issue authorized but unissued ordinary shares, and the selling shareholders identified in a prospectus supplement may sell ordinary shares, without further shareholder action, unless shareholder action is required by applicable law or by the rules of a stock exchange or quotation system on which any series of our shares may be listed or quoted.

Dividend and Liquidation Rights. Holders of ordinary shares are entitled to receive equally, share for share, any dividends that may be declared in respect of our ordinary shares by the Board of Directors out of funds legally available therefor. If, in the future, we declare cash dividends, such dividends will be payable in U.S. dollars. In the event of our liquidation, after satisfaction of liabilities to creditors, holders of ordinary shares are entitled to share pro rata in our net assets. Such rights may be affected by the grant of preferential dividend or distribution rights to the holders of a class or series of preferred shares that may be authorized in the future. Our Board of Directors has the power to declare such interim dividends as it determines. Declaration of a final dividend (not exceeding the amounts proposed by our Board of Directors) requires shareholder approval by adoption of an ordinary resolution. Failure to obtain such shareholder approval does not affect previously paid interim dividends.

6

Voting, Shareholder Meetings and Resolutions. Holders of ordinary shares have one vote for each ordinary share held on all matters submitted to a vote of holders of ordinary shares. These voting rights may be affected by the grant of any special voting rights to the holders of a class or series of preferred shares that may be authorized in the future. Pursuant to Jersey law, an annual general meeting shall be held once every calendar year at the time (within a period of not more than 18 months after the last preceding annual general meeting) and at the place as may be determined by the Board of Directors. The quorum required for an ordinary meeting of shareholders consists of shareholders present in person or by proxy who hold or represent between them a majority of the outstanding shares entitled to vote at such meeting.

An ordinary resolution (such as a resolution for the declaration of dividends) requires approval by the holders of a majority of the voting rights represented at a meeting, in person or by proxy, and voting thereon.

Amendments to Governing Documents. A special resolution (such as, for example, a resolution amending our Memorandum of Association or Articles of Association or approving any change in authorized capitalization, or a liquidation or winding-up) requires approval of the holders of two-thirds of the voting rights represented at the meeting, in person or by proxy, and voting thereon. A special resolution can only be considered if shareholders receive at least fourteen days’ prior notice of the meeting at which such resolution will be considered.

Requirements for Advance Notification of Shareholder Nominations and Proposals. Our Articles of Association establish advance notice and related procedures with respect to shareholder proposals and nomination of candidates for election as directors.

Limits on Written Consents. Any action required or permitted to be taken by the shareholders must be effected at a duly called annual or special meeting of shareholders and may not be effected by any consent in writing in lieu of a meeting of such shareholders.

Transfer of Shares and Notices. Fully paid ordinary shares are issued in registered form and may be freely transferred pursuant to the Articles of Association unless the transfer is restricted by applicable securities laws or prohibited by another instrument. Each shareholder of record is entitled to receive at least fourteen days’ prior notice (excluding the day of notice and the day of the meeting) of an ordinary shareholders’ meeting and of any shareholders’ meeting at which a special resolution is to be adopted. For the purposes of determining the shareholders entitled to notice and to vote at the meeting, the Board of Directors may fix a date as the record date for any such determination.

Modification of Class Rights. The rights attached to any class (unless otherwise provided by the terms of issue of that class), such as voting, dividends and the like, may be varied with the sanction of a special resolution passed at a separate general meeting of the holders of the shares of that class.

Election and Removal of Directors. The ordinary shares do not have cumulative voting rights in the election of directors. As a result, the holders of ordinary shares that represent more than 50% of the voting power have the power to elect any of our directors who are up for election. All of our directors will be elected at each annual meeting.

Our Board of Directors currently consists of 12 directors. Our Articles of Association state that shareholders may only remove a director for cause. Our Board of Directors has sole power to fill any vacancy occurring as a result of the death, disability, removal or resignation of a director or as a result of an increase in the size of the Board of Directors.

Preferred Shares

We have 50,000,000 authorized preferred shares. As of December 31, 2021, we have 11,500,000 preferred shares issued and outstanding. The Board of Directors has the authority to issue the preferred shares in one or

7

more series and to fix the rights, preferences, privileges and restrictions of such shares, including dividend rights, dividend rates, conversion rights, voting rights, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any series, without further vote or action by the shareholders.

When we offer to sell a particular series of preferred shares, we will describe the specific terms of the securities in a supplement to this prospectus. The preferred shares will be issued under a statement of rights relating to each series of preferred shares and they are also subject to our Articles of Association.

Our Board may issue authorized preferred shares without further shareholder action, unless shareholder action is required by applicable law or by the rules of a stock exchange or quotation system on which any series of our shares may be listed or quoted.

All preferred shares offered will be fully paid and non-assessable. Any preferred shares that are issued may have priority over the ordinary shares with respect to dividend or liquidation rights or both.

The purpose of authorizing the Board of Directors to issue preferred shares and to determine their rights and preferences is to eliminate delays associated with a shareholder vote on specific issuances. The issuance of preferred shares, while providing desirable flexibility in connection with possible equity financings, acquisitions and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from acquiring, a majority of our outstanding voting shares.

Convertible Preferred Shares

On June 12, 2020, we closed an offering pursuant to an effective shelf registration statement on Form S-3 (Registration File No. 333-228021) (the “Shelf Registration Statement”), in which we agreed to issue and sell to certain underwriters 11,500,000 5.50% Series A Mandatory Convertible Preferred Shares, par value $0.01 per share and liquidation preference $100.00 per share (the “MCPS”), in a registered public offering (“MCPS Offering”). In connection with the MCPS Offering, on June 12, 2020, we adopted a Statement of Rights (the “Statement of Rights”) to establish the preferences, limitations and relative rights of the MCPS.

Unless converted earlier in accordance with the terms of the Statement of Rights, each MCPS will convert automatically on the mandatory conversion date, which is expected to be June 15, 2023, into between 1.0754 and 1.3173 ordinary shares, subject to anti-dilution and other adjustments. The number of ordinary shares issuable upon conversion will be determined based on the average volume weighted average price per ordinary share over the 20 consecutive trading day period beginning on, and including, the 21st scheduled trading day immediately prior to June 15, 2023.

The ordinary shares rank junior to MCPS with respect to the payment of dividends and amounts payable in the event of the our liquidation, dissolution or winding up of its affairs. Subject to certain exceptions, so long as any MCPS remains outstanding, no dividend or distributions will be declared or paid on ordinary shares or any other class or series of share capital ranking junior to the MCPS, and no ordinary shares or any other class or series shares ranking junior or on parity with the MCPS shall be, directly or indirectly, purchased, redeemed, or otherwise acquired for consideration by us or any of our subsidiaries unless all accumulated and unpaid dividends for all preceding dividend periods have been declared and paid upon, or a sufficient sum of cash or number of ordinary shares has been set aside for the payment of such dividends upon, all outstanding MCPS.

In addition, upon our voluntary or involuntary liquidation, winding-up or dissolution, each holder of MCPS will be entitled to receive a liquidation preference in the amount of $100.00 per MCPS, plus an amount equal to accumulated and unpaid dividends on such shares, whether or not declared, to, but excluding, the date fixed for liquidation, winding-up or dissolution, to be paid out of our assets legally available for distribution to shareholders after satisfaction of liabilities to creditors and holders of our share capital ranking senior to the MCPS as to distribution rights upon our liquidation, winding-up or dissolution, and before any payment or distribution is made to holders of any class or series of share capital ranking junior to the MCPS as to distribution rights upon our liquidation, winding-up or dissolution, including, without limitation, the ordinary shares.

8

The holders of the MCPS do not have voting rights except as described below and as specifically required by Jersey law from time to time.

Whenever dividends on any MCPS have not been declared and paid for the equivalent of six or more dividend periods, whether or not for consecutive dividend periods (a “nonpayment”), the authorized number of directors on our Board of Directors will, at the next annual meeting of shareholders or at a special meeting of shareholders as provided below, automatically be increased by two and the holders of record of the MCPS, voting together as a single class with holders of record of any and all other series of voting preferred shares then outstanding, will be entitled, at the next annual or at a special meeting of our shareholders, to vote for the election of a total of two additional members of the Board of Directors (“preferred share directors”); provided that the election of any such directors will not cause us to violate the corporate governance requirements of NYSE (or any other exchange or automated quotation system on which its securities may be listed or quoted) that requires listed or quoted companies to have a majority of independent directors; and provided further that the Board of Directors shall, at no time, include more than two preferred share directors.

In the event of a nonpayment, the holders of at least 25% of the MCPS and any other series of voting preferred shares may request that a special meeting of shareholders be called to elect such preferred share directors (provided that, to the extent permitted by our Memorandum and Articles of Association, if the next annual or a special meeting of shareholders is scheduled to be held within 90 days of the receipt of such request, the election of such preferred share directors will be included in the agenda for and will be held at such scheduled annual or special meeting of shareholders). The preferred share directors will stand for reelection annually, at each subsequent annual meeting of the shareholders, so long as the holders of the MCPS continue to have such voting rights.

At any meeting at which the holders of the MCPS are entitled to elect preferred share directors, the holders of a majority of the then outstanding MCPS and all other series of voting preferred shares, present in person or represented by proxy, will constitute a quorum and the vote of the holders of a majority of such MCPS and other voting preferred shares so present or represented by proxy at any such meeting at which there shall be a quorum shall be sufficient to elect the preferred share directors.

Any preferred share director may be removed at any time, with cause or without cause by the holders of record of a majority in voting power of the outstanding MCPS and any other series of voting preferred shares then outstanding (voting together as a class) when they have the voting rights described above. In the event that a nonpayment shall have occurred and there shall not have been a nonpayment remedy, any vacancy in the office of a preferred share director (other than prior to the initial election after a nonpayment) may be filled by the written consent of the preferred share director remaining in office, except in the event that such vacancy is created as a result of such preferred share director being removed or if no preferred share director remains in office, such vacancy may be filled by a vote of the holders of record of a majority in voting power of the outstanding MCPS and any other series of voting preferred shares then outstanding (voting together as a single class) when they have the voting rights described above; provided that the election of any such preferred share directors will not cause us to violate the corporate governance requirements of NYSE (or any other exchange or automated quotation system on which our securities may be listed or quoted) that requires listed or quoted companies to have a majority of independent directors. The preferred share directors will each be entitled to one vote per director on any matter that comes before our Board of Directors for a vote.

Comparison of United States and Jersey Corporate Law

The following discussion is a summary of the material differences between United States and Jersey corporate law relevant to an investment in the ordinary shares. The following discussion is based upon laws and relevant interpretations thereof in effect as of the date of this prospectus, all of which are subject to change.

As in most United States jurisdictions, unless approved by a special resolution of our shareholders, our directors do not have the power to take certain actions, including an amendment of our Memorandum of

Association or Articles of Association or an increase or reduction in our authorized capital. Directors of a Jersey corporation, without shareholder approval, in certain instances may, among other things, implement certain sales, transfers, exchanges or dispositions of assets, property, parts of the business or securities of the corporation; or any combination thereof, if they determine any such action is in the best interests of the corporation, its creditors or its shareholders.

As in most United States jurisdictions, the board of directors of a Jersey corporation is charged with the management of the affairs of the corporation. In most United States jurisdictions, directors owe a fiduciary duty to the corporation and its shareholders, including a duty of care, pursuant to which directors must properly apprise themselves of all reasonably available information, and a duty of loyalty, pursuant to which they must protect the interests of the corporation and refrain from conduct that injures the corporation or its shareholders or that deprives the corporation or its shareholders of any profit or advantage. Many United States jurisdictions have enacted various statutory provisions that permit the monetary liability of directors to be eliminated or limited. Jersey law protecting the interests of shareholders may not be as protective in all circumstances as the law protecting shareholders in United States jurisdictions. Under our Articles of Association, we are required to indemnify every present and former officer of ours out of our assets against any loss or liability incurred by such officer by reason of being or having been such an officer. The extent of such indemnities shall be limited in accordance with the provisions of the Companies (Jersey) Law 1991, as amended.

In most United States jurisdictions, the Board of Directors is permitted to authorize share repurchases without shareholder consent. Jersey law does not permit share repurchases without shareholder consent. However, our Articles of Association permit our Board of Directors to convert any of our shares that we wish to purchase into redeemable shares, and thus effectively allow our Board of Directors to authorize share repurchases (which shall be effected by way of redemption) without shareholder consent, consistent with the practice in most United States jurisdictions.

The form of indentures filed with the registration statement of which this prospectus forms a part contain certain of these terms, which may be modified in connection with the offering of any debt securities.

Senior Debt

Each of Aptiv PLC, Aptiv Corp. and AGFL will issue under its senior indenture the debt securities that will constitute part of the senior debt of such issuer. These senior debt securities will rank equally and pari passu with all other unsecured and unsubordinated debt of such issuer.

Subordinated Debt

Each of Aptiv PLC and Aptiv Corp. will issue under its subordinated indenture the debt securities that will constitute part of the subordinated debt of such issuer. These subordinated debt securities will be subordinate and junior in right of payment, to the extent and in the manner set forth in the relevant subordinated indenture, to all “senior indebtedness” of such issuer. The specific subordination terms will be set forth in a supplemental indenture to the relevant subordinated indenture and described in the prospectus supplement for the relevant series of debt.

Guarantees

Each prospectus supplement will describe any guarantees of debt securities for the benefit of the series of debt securities to which it relates. Debt securities issued by Aptiv PLC may be guaranteed by any of the subsidiary registrants under the registration statement of which this prospectus forms a part. Debt securities issued by Aptiv Corp. or AGFL will be guaranteed by Aptiv PLC and may be guaranteed by any of the subsidiary registrants. The guarantees will be full and unconditional on a joint and several basis. Each of the subsidiary guarantors is 100% owned by Aptiv PLC.

Concerning the Trustee and the Registrar and Paying Agent

Unless otherwise provided in respect of a series of debt securities, Wilmington Trust, National Association is the Trustee under each indenture and Deutsche Bank Trust Company Americas is the Registrar and Paying Agent with regard to each series of debt securities. The Trustee and its affiliates have engaged in, and may in the future engage in, financial or other transactions with the Company, Aptiv Corp, AGFL and the Guarantors and their and our affiliates in the ordinary course of their respective businesses, subject to the Trust Indenture Act of 1939. The Registrar and Paying Agent have engaged in, are currently engaged in, and may in the future engage in financial or other transactions with the issuers and the guarantors and their and our affiliates in the ordinary course of their respective businesses.

Governing Law

The indentures and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

DESCRIPTION OF WARRANTS

Aptiv PLC may issue warrants to purchase its debt or equity securities or securities of third parties or other rights, including rights to receive payment in cash or securities based on the value, rate or price of one or more specified commodities, currencies, securities or indices, or any combination of the foregoing, subject to the consent of the Jersey Financial Services Commission, if required. Aptiv Corp. may also issue warrants to purchase its debt securities or securities of third parties or other rights, including rights to receive payment in cash or securities based on the value, rate or price of one or more specified commodities, currencies, securities or indices, or any combination of the foregoing. Warrants may be issued independently or together with any other securities and may be attached to, or separate from, such securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between the issuer of such warrants and a warrant agent. The terms of any warrants to be issued and a description of the material provisions of the applicable warrant agreement will be set forth in the applicable prospectus supplement.

The applicable prospectus supplement will describe the following terms of any warrants in respect of which this prospectus and such prospectus supplement is being delivered:

13

DESCRIPTION OF PURCHASE CONTRACTS

Aptiv PLC may, subject to the consent of the Jersey Financial Services Commission, if required, issue purchase contracts for the purchase or sale of:

Aptiv Corp. may issue purchase contracts for the purchase or sale of:

Each purchase contract will entitle the holder thereof to purchase or sell, and obligate the issuer thereof to sell or purchase, on specified dates, such securities, currencies or commodities at a specified purchase price, which may be based on a formula, all as set forth in the applicable prospectus supplement. Aptiv PLC or Aptiv Corp., as applicable, may, however, satisfy its obligations, if any, with respect to any purchase contract by delivering the cash value of such purchase contract or the cash value of the property otherwise deliverable or, in the case of purchase contracts on underlying currencies, by delivering the underlying currencies, as set forth in the applicable prospectus supplement. The applicable prospectus supplement will also specify the methods by which the holders may purchase or sell such securities, currencies or commodities and any acceleration, cancellation or termination provisions or other provisions relating to the settlement of a purchase contract.

The purchase contracts may require the issuer thereof to make periodic payments to the holders thereof or vice versa, which payments may be deferred to the extent set forth in the applicable prospectus supplement, and

14

those payments may be unsecured or prefunded on some basis. The purchase contracts may require the holders thereof to secure their obligations in a specified manner to be described in the applicable prospectus supplement. Alternatively, purchase contracts may require holders to satisfy their obligations thereunder when the purchase contracts are issued. The issuer’s obligation to settle such pre-paid purchase contracts on the relevant settlement date may constitute indebtedness. Accordingly, pre-paid purchase contracts will be issued under one or more of the indentures.

15

DESCRIPTION OF UNITS

As specified in the applicable prospectus supplement, subject to the consent of the Jersey Financial Services Commission, if required, Aptiv PLC may issue units consisting of one or more purchase contracts, warrants, debt securities, preferred shares, ordinary shares or any combination of such securities and Aptiv Corp. may issue units consisting of one or more purchase contracts, warrants, debt securities or any combination of such securities. The applicable supplement will describe:

FORMS OF SECURITIES

Each debt security, warrant and unit will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Certificated securities in definitive form and global securities will be issued in registered form. Definitive securities name you or your nominee as the owner of the security, and in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the trustee, registrar, paying agent or other agent, as applicable. Global securities name a depositary or its nominee as the owner of the debt securities, warrants or units represented by these global securities. The depositary maintains a computerized system that will reflect each investor’s beneficial ownership of the securities through an account maintained by the investor with its broker/dealer, bank, trust company or other representative, as we explain more fully below.

Global Securities

Registered Global Securities. Aptiv PLC, Aptiv Corp. or AGFL may issue the registered debt securities, warrants and units, as applicable, in the form of one or more fully registered global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or nominee. In those cases, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by registered global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a registered global security may not be transferred except as a whole by and among the depositary for the registered global security, the nominees of the depositary or any successors of the depositary or those nominees.

If not described below, any specific terms of the depositary arrangement with respect to any securities to be represented by a registered global security will be described in the prospectus supplement relating to those securities. We anticipate that the following provisions will apply to all depositary arrangements.

Ownership of beneficial interests in a registered global security will be limited to persons, called participants, that have accounts with the depositary or persons that may hold interests through participants. Upon the issuance of a registered global security, the depositary will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal or face amounts of the securities beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the securities will designate the accounts to be credited. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the

16

depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants. The laws of some states may require that some purchasers of securities take physical delivery of these securities in definitive form. These laws may impair your ability to own, transfer or pledge beneficial interests in registered global securities.

So long as the depositary, or its nominee, is the registered owner of a registered global security, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the securities represented by the registered global security for all purposes under the applicable indenture, warrant agreement, guaranteed trust preferred security or unit agreement. Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities under the applicable indenture, warrant agreement, guaranteed trust preferred security or unit agreement. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for that registered global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest, to exercise any rights of a holder under the applicable indenture, warrant agreement, guaranteed trust preferred security or unit agreement. We understand that under existing industry practices, if Aptiv PLC, Aptiv Corp. or AGFL requests any action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the applicable indenture, warrant agreement or unit agreement, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

Principal, premium, if any, and interest payments on debt securities, and any payments to holders with respect to warrants or units, represented by a registered global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of Aptiv PLC, Aptiv Corp., AGFL, the trustees, the warrant agents, the unit agents or any other agent of Aptiv PLC, Aptiv Corp. or AGFL, agent of the trustees or agent of the warrant agents or unit agents will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

We expect that the depositary for any of the securities represented by a registered global security, upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or other property to holders on that registered global security, will immediately credit participants’ accounts in amounts proportionate to their respective beneficial interests in that registered global security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in a registered global security held through participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of those participants.

If the depositary for any of these securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Securities Exchange Act of 1934, and a successor depositary registered as a clearing agency under the Securities Exchange Act of 1934 is not appointed by us within 90 days, Aptiv PLC, Aptiv Corp. or AGFL, as applicable, will issue securities in definitive form in exchange for the registered global security that had been held by the depositary. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee, warrant agent, unit agent or other relevant agent of theirs or of Aptiv PLC, Aptiv Corp. or AGFL. It is expected that the depositary’s instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary.
