Preliminary Prospectus Supplement

(To Prospectus dated August 1, 2024)

$     % Fixed-to-Fixed Reset Rate Junior Subordinated Notes due 20 

Aptiv PLC, a public limited company incorporated under the laws of Jersey (the “Issuer”), and Aptiv Global Financing Designated Activity Company (formerly known as 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  % Fixed-to-Fixed Reset Rate Junior Subordinated Notes due 20  (the “Notes”). The Notes will bear interest (i) from and including the date of original issuance to, but excluding,    , 20  at an annual rate of  % and (ii) from and including   , 20 , during each Interest Reset Period (as defined herein) at an annual rate equal to the Five-Year Treasury Rate (as defined in herein) as of the most recent Reset Interest Determination Date (as defined herein), plus  %. The Notes will mature on   , 20 . Interest on the Notes will, subject to our right to defer interest payments (as described below), be payable semi-annually in arrears on    and     of each year, beginning on    , 2025. See “Description of Notes—Principal, Maturity and Interest”

So long as no Event of Default (as defined herein) with respect to the Notes has occurred and is continuing, we may, at our option, defer interest payments on the Notes on one or more occasions, from time to time, for up to 20 consecutive semi-annual Interest Payment Periods (as defined herein). During any deferral period, interest on the Notes will continue to accrue at the then-applicable interest rate on the Notes, and, in addition, interest on deferred interest will accrue at the then-applicable interest rate on the Notes, compounded semi-annually, to the extent permitted by applicable law, as described in this prospectus supplement. See “Description of Notes—Option to Defer Interest Payments.”

The Issuers may, at their option, redeem all or part of the Notes at the times and at the redemption prices described herein. See “Description of Notes—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—Redemption—Tax Redemption.”

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 guarantee will be general unsecured and subordinated obligations of the Issuers and the Guarantor, respectively, and will rank (a) junior and subordinate in right of payment with all of the Issuers’ and the Guarantor’s respective existing and future Senior Indebtedness (as defined herein), including all of Aptiv PLC’s outstanding notes, which are also issued or guaranteed by Aptiv Corporation and Aptiv Global Financing Designated Activity Company, and borrowings under Aptiv’s credit facilities, and (b) equal in right of payment with all of the Issuers’ and the Guarantor’s respective future unsecured indebtedness that may be incurred from time to time if the terms of such indebtedness provide that it ranks equally with the Notes in right of payment. The Notes and the guarantee 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 (other than the Guarantor). See “Description of Notes—Ranking; Subordination.”

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-8 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 the facilities of The Depository Trust Company and its participants, including Clearstream Banking, société anonyme (“Clearstream”) and Euroclear Bank SA/NV (“Euroclear”), on or about    , 2024.

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; 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 Reports on Form 10-Q for the three months ended March 31, 2024 and June 30, 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.

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

The Notes are subordinated to all of the Issuers’ and the Guarantor’s indebtedness (other than any unsecured indebtedness that the Issuers or the Guarantor may in the future incur that ranks junior to or pari passu with the Notes).

Pursuant to the terms of the indenture that will govern the Notes, the Notes and the related guarantee will be subordinated in right of payment to all of the Issuers’ and the Guarantor’s existing and future Senior Indebtedness (as defined herein). This means that, in the event of (a) the Issuers’ or the Guarantor’s dissolution, winding-up, liquidation or reorganization, (b) the Issuers’ or the Guarantor’s failure to pay any interest, principal or other monetary amounts due on any of their Senior Indebtedness when due (and continuance of that default beyond any applicable grace period) or (c) acceleration of the maturity of any of the Issuers’ or the Guarantor’s Senior Indebtedness as a result of a default, we will not be permitted to make any payments on the Notes until, in the case of clause (a), all amounts due or to become due on all of such Senior Indebtedness have been paid in full, or, in the case of clauses (b) and (c), all amounts due on such Senior Indebtedness have been paid in full. See “Description of Notes—Subordination.” Additionally, the Notes will rank equally in right of payment with any future unsecured indebtedness that the Issuers or the Guarantor may incur from time to time if the terms of such indebtedness provide that it ranks equally with the Notes in right of payment.

Our debt exposes us to certain risks.

As of June 30, 2024, after giving effect to the Transactions, the total indebtedness of the Issuers and the Guarantor would have been $  million, of which $  million would have ranked senior in right of payment to the Notes. 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

S-8

available borrowings under our revolving credit facility as of June 30, 2024. Additionally, the Notes offered hereby and all of our senior notes (including the Senior Notes) contain no restrictive covenants on our ability to incur more debt, including debt that ranks senior in right of payment to the Notes. 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 revolving credit facility 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 revolving credit facility 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 revolving credit facility 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 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 will not be able to make payments on the Notes.

Any default under the agreements governing our indebtedness, including a default under our credit agreements 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 (and in the case of payment default, will) 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 agreements 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 agreements:

S-9

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 $23,236 million and total liabilities of $5,927 million, including total debt of $34 million, or 94% of our total assets and 46% of our total liabilities, as of June 30, 2024 (giving effect to intercompany eliminations).

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 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 June 30, 2024, the Issuers and the Guarantor had no secured debt. However, the indenture that will govern the Notes will not, and the indenture governing our senior notes does not, restrict our ability to 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 and our other obligations. Holders

S-10

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.

We can defer interest payments on the Notes on one or more occasions, from time to time, for up to 20 consecutive semi-annual interest payment periods. This may affect the market price of the Notes.

So long as no Event of Default (as defined herein) with respect to the Notes has occurred and is continuing, we may, at our option, defer interest payments on the Notes on one or more occasions, from time to time, for up to 20 consecutive semi-annual interest payment periods, except that no such Optional Deferral Period may extend beyond the Stated Maturity of the Notes or end on a day other than the day immediately preceding an interest payment date, and we may not begin a new Optional Deferral Period, and may not pay current interest on the Notes until we have paid all accrued interest on the Notes from the previous Optional Deferral Period. As a result, we may elect, on one or more occasions, not to pay interest on the Notes for up to ten years. Moreover, following the end of any Optional Deferral Periods, if all amounts then due on the Notes are paid, we could immediately start a new Optional Deferral Period of up to 20 consecutive semi-annual interest payment periods. No interest will be due or payable on the Notes during any such Optional Deferral Period, except upon a redemption of the Notes on any redemption date during such Optional Deferral Period (in which case all accrued and unpaid interest (including, to the extent permitted by applicable law, any interest on the deferred interest (“Compound Interest”)) on the Notes to be redeemed to, but excluding, such redemption date will be due and payable on such redemption date), or unless the principal of and interest on the Notes shall have been declared due and payable as the result of an Event of Default with respect to the Notes (in which case all accrued and unpaid interest, including, to the extent permitted by applicable law, any Compound Interest, on the Notes shall become due and payable). Instead, interest on the Notes would be deferred but would continue to accrue at the then-applicable interest rate on the Notes. In addition, during any Optional Deferral Period, Compound Interest would accrue at the then-applicable interest rate on the Notes (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes), compounded semi-annually, to the extent permitted by applicable law. If we exercise this interest deferral right, the Notes may trade at a price that does not reflect the value of accrued and unpaid interest on the Notes or that is otherwise substantially less than the price at which the Notes would have traded if we had not exercised such interest deferral right. If we exercise this interest deferral right and you sell your Notes during an Optional Deferral Period, you may not receive the same return on your investment as a holder that continues to hold its Notes until we pay the deferred interest following the end of such Optional Deferral Period. In addition, as a result of our right to defer interest payments, the market price of the Notes may be more volatile than other securities that do not have these rights.

We are not permitted to pay current interest on the Notes until we have paid all outstanding deferred interest, and this could have the effect of extending interest deferral periods.

During an Optional Deferral Period, we will be prohibited from paying current interest on the Notes until we have paid all accrued and unpaid deferred interest plus any accrued interest thereon. As a result, we may not be able to pay current interest on the Notes if we do not have available funds to pay all accrued and unpaid deferred interest plus any accrued interest thereon (including, to the extent permitted by applicable law, Compounded Interest).

Holders of the Notes subject to United States federal income taxation may have to pay taxes on interest before they receive payments from us.

If we defer payments of interest on the Notes, the Notes will be treated at that time, solely for purposes of the United States federal income tax original issue discount rules, as having been retired and reissued with original issue discount. A holder of the Notes subject to United States federal income tax on a net income basis

S-11

would be required to accrue that original issue discount for United States federal income tax purposes in respect of such holder’s proportionate share of the accrued but unpaid interest on the Notes, regardless of such holder’s method of tax accounting. As a result, a holder will be required to include the accrued interest in such holder’s gross income for United States federal income tax purposes even though such holder will not have received any associated cash. A holder’s adjusted tax basis in a Note generally will be increased by such amounts that it was required to include in gross income. Unpaid interest accrued on the Notes during an Optional Deferral Period will be payable on the Interest Payment Date immediately following the last day of such Optional Deferral Period. If a holder sells its Notes on or before the record date for such Interest Payment Date, then all of the interest accrued on such Notes during the Optional Deferral Period will be paid to the person who is the registered owner of those Notes at the close of business on such record date, and the holder that sold those Notes will not receive from us any of the interest that accrued on those Notes during the Optional Deferral Period and that such holder reported as income for tax purposes. Holders should consult with their tax advisors regarding the tax consequences of an investment in the Notes. For more information regarding the U.S. tax consequences of owning and disposing of the Notes, see “Material U.S. Federal Income Tax Considerations.”

Holders of the Notes will have limited rights of acceleration.

Holders of the Notes and the trustee under the indenture that will govern the Notes may accelerate payment of the principal and interest on the Notes only upon the occurrence and continuation of certain Events of Default. Payment of principal and interest on the Notes may be accelerated upon the occurrence of an Event of Default related to failure to pay interest within 30 days after it is due, failure to pay principal or premium, if any, on the Notes when due and certain events of bankruptcy, insolvency, receivership or reorganization relating to the Issuers. Holders of the Notes and the trustee will not have the right to accelerate payment of the principal or interest on the Notes upon the breach of any other covenant in the indenture that will govern the Notes. See “Description of Notes—Defaults.”

We may redeem the Notes before they mature.

We may redeem the Notes in whole or in part at our option as described under “Description of Notes—Redemption.” These redemption rights may, depending on prevailing market conditions at the time, create reinvestment risk for the holders of the Notes in that they may be unable to find a suitable replacement investment with a comparable return to the Notes.

The interest rate will reset for the Notes on     , 20 and each subsequent Reset Date, and any interest payable after a Reset Date may be less than an earlier interest rate.

The interest rate on the Notes for each Interest Reset Period will equal the Five-Year Treasury Rate as of the most recent Reset Interest Determination Date, plus  %. Therefore, the interest rate after     , 20 could be less than the initial interest rate applicable to the Notes, and any interest payable after a subsequent Reset Date may be less than the interest rate for a prior period. We have no control over the factors that may affect United States Treasury rates, including geopolitical conditions and economic, financial, political, regulatory, judicial or other events. See “Description of Notes—Principal, Maturity and Interest.” In the past, United States Treasury rates have experienced significant fluctuations. Historical levels, fluctuations and trends of United States Treasury rates are not necessarily indicative of future levels. Any historical upward or downward trend in United States Treasury rates is not an indication that United States Treasury rates are more or less likely to increase or decrease at any time after    , 20 , and historical United States Treasury rates are not an indication of future Five-Year Treasury Rates.

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-12

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 a listing is obtained, the Issuers will have no obligation to maintain such listing, 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. In addition, we may redeem the Notes if a rating agency makes certain changes in the equity credit methodology for securities such as the Notes.

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.

In addition, we may, at our option, redeem the Notes, in whole, but not in part, if a rating agency makes certain changes in the equity credit methodology for securities such as the Notes. See “Description of Notes—Redemption—Redemption Following a Rating Agency Event.”

The Notes are not protected by restrictive covenants.

The indenture that will govern the Notes will not contain any financial or operating covenants or restrictions on the payments of dividends (except during an Optional Deferral Period), the making of investments, the incurrence of indebtedness or the purchase or prepayment (except, with respect to securities that rank equally with or junior to the Notes in right of payment, during an Optional Deferral Period) of securities by us or any of our subsidiaries. In addition, the indenture that will govern the Notes will not require us to achieve or maintain any minimum financial results relating to our financial position or results of operations.

Our ability to recapitalize, incur additional debt and take a number of other actions that are not limited by the terms of the Notes could have the effect of diminishing our ability to make payments on the Notes when due, and require us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, which would reduce the availability of cash flow to fund our operations, working capital and capital expenditures.

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

The Notes will be issued only in minimum denominations of $200,000 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 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 of $200,000 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.

S-13

USE OF PROCEEDS

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 terms “Company” and “Aptiv” refer only to Aptiv PLC and not to any of its subsidiaries; the term “Co-Obligor” refers only to Aptiv Global Financing Designated Activity Company (formerly known as Aptiv Global Financing Limited) (“AGFDAC”), an indirect subsidiary of Aptiv PLC, and not to any of its subsidiaries; the term “Issuers” refers to Aptiv PLC and AGFDAC; 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.”

The Issuers will issue the  % Fixed-to-Fixed Reset Rate Junior Subordinated Notes due 20  (the “Notes”) pursuant to a Subordinated Notes Indenture, to be dated as of    , 2024 (the “Base Indenture”), as supplemented by a first supplemental indenture, to be dated as of    , 2024 (the “First 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 and Paying Agent”). The Notes will be issued as a separate series under the Indenture.

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 bear interest (i) from and including the Issue Date to, but excluding,    , 20 at an annual rate of  % and (ii) from and including    , 20 during each Interest Reset Period (as defined below) at an annual rate equal to the Five-Year Treasury Rate (as defined below) as of the most recent Reset Interest Determination Date (as defined below), plus  %. The Notes will mature on    , 20 . Interest on the Notes will accrue from    , 2024 and will, subject to our right to defer interest payments (as described below under “—Option to Defer Interest Payments”), be payable semi-annually in arrears on      and      of each year (each, an “Interest Payment Date”), beginning on    , 2025. If interest payments are deferred or otherwise

S-18

not paid, they will accrue and compound until paid at the same rate at which the Notes bear interest (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes) to the extent permitted by law. As permitted by the terms of the Notes, if interest payments are deferred or otherwise not paid up to a redemption date that does not fall on an Interest Payment Date, they will accrue and compound until paid at the same rate at which the Notes bear interest (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes) to the extent permitted by law. The amount of interest payable for any interest accrual period will be computed on the basis of a 360-day year consisting of twelve 30-day months. The amount of interest payable for any period shorter than a full semi-annual period for which interest is computed will be computed on the basis of the number of days in the period using 30-day calendar months. The Notes will be subject to redemption at our option as described below under “—Redemption.”

In this prospectus supplement the term “interest” includes semi-annual interest payments and applicable interest on interest payments accrued but not paid on the applicable Interest Payment Date.

“Business Day” means any day other than a Saturday, a Sunday or a day on which the Federal Reserve Bank of New York is authorized or required by law or executive order to close or be closed.

Unless all of the outstanding Notes have been redeemed, the Issuers will appoint a calculation agent (the “Calculation Agent”) with respect to the Notes prior to the applicable Reset Interest Determination Date. The Issuers or any of their Affiliates may assume the duties of the Calculation Agent. The applicable interest rate for each Interest Reset Period will be determined by the Calculation Agent as of the applicable Reset Interest Determination Date. If the Issuers or one of their Affiliates is not the Calculation Agent, the Calculation Agent will notify the Issuers of the interest rate for the relevant Interest Reset Period promptly upon such determination. The Issuers will notify the Paying Agent of such interest rate, promptly upon making or being notified of such determination. The Calculation Agent’s determination of any interest rate and its calculation of the amount of interest for any Interest Reset Period will be conclusive and binding absent manifest error, will be made in the Calculation Agent’s sole discretion and, notwithstanding anything to the contrary in the documentation relating to the Notes, will become effective without consent from any other person or entity. Such determination of any interest rate and calculation of the amount of interest will be on file at the Issuers’ principal offices and will be made available to any Holder of the Notes upon request. In no event shall the Trustee be the Calculation Agent, nor shall it have any liability for any determination made by or on behalf of such Calculation Agent.

“Five-Year Treasury Rate” means, as of any Reset Interest Determination Date, the average of the yields on actively traded United States Treasury securities adjusted to constant maturity, for five-year maturities, for the most recent five Business Days appearing under the caption “Treasury Constant Maturities” in the most recent H.15.

If the Five-Year Treasury Rate cannot be determined pursuant to the method described above, the Calculation Agent, after consulting such sources as it deems comparable to any of the foregoing calculations, or any such source as it deems reasonable from which to estimate the Five-Year Treasury Rate, will determine the Five-Year Treasury Rate in its sole discretion, provided that if the Calculation Agent determines there is an industry-accepted successor Five-Year Treasury Rate, then the Calculation Agent will use such successor rate. If the Calculation Agent has determined a substitute or successor base rate in accordance with the foregoing, the Calculation Agent in its sole discretion may determine the business day convention, the definition of “Business Day” and the Reset Interest Determination Date to be used and any other relevant methodology for calculating such substitute or successor base rate, including any adjustment factor needed to make such substitute or successor base rate comparable to the Five-Year Treasury Rate, in a manner that is consistent with industry-accepted practices for such substitute or successor base rate.

“H.15” means the daily statistical release designated as such, or any successor publication as determined by the Calculation Agent in its sole discretion, published by the Federal Reserve Board, and “most recent H.15” means the H.15 published closest in time but prior to the close of business on the applicable Reset Interest Determination Date.

S-19

“Reset Date” means     , 20 and each date falling on the five-year anniversary of the preceding Reset Date.

“Interest Reset Period” means the period from and including     , 20 to but excluding the next following Reset Date and thereafter each period from and including a Reset Date to but excluding the next following Reset Date, or the Stated Maturity or date of redemption, as the case may be.

“Reset Interest Determination Date” means, in respect of any Interest Reset Period, the day falling two Business Days prior to the beginning of the applicable Interest Reset Period.

Interest will be paid to the person in whose name a Note is registered at the close of business on     or      (whether or not a Business Day), as the case may be, immediately preceding the relevant Interest Payment Date (each, a “Regular Record Date”).

If any Interest Payment Date, the Stated Maturity or a redemption date falls on a day that is not a Business Day, the required payment will be made on the next succeeding Business Day with the same force and effect as if made on such scheduled payment date, and no interest on such payment will accrue in respect of the delay.

The Issuers will issue the Notes in fully registered form, without coupons, in minimum denominations of $200,000 and integral multiples of $1,000 in excess thereof.

Option to Defer Interest Payments

So long as no Event of Default (as defined below under “—Defaults”) with respect to the Notes has occurred and is continuing, the Issuers may, at their option, defer interest payments on the Notes on one or more occasions, from time to time, for up to 20 consecutive semi-annual Interest Payment Periods (as defined below) (each such deferral period, which will commence on the Interest Payment Date on which the first such deferred interest payment otherwise would have been made, an “Optional Deferral Period”), except that no such Optional Deferral Period may extend beyond the Stated Maturity of the Notes or end on a day other than the day immediately preceding an Interest Payment Date, and the Issuers may not begin a new Optional Deferral Period, and may not pay current interest on the Notes until the Issuers have paid all accrued interest on the Notes from the previous Optional Deferral Period.

If the Issuers defer interest for a period of 20 consecutive Interest Payment Periods from the commencement of an Optional Deferral Period, the Issuers will be required to pay all accrued and unpaid interest at the conclusion of the 20 consecutive Interest Payment Periods. If the Issuers fail to pay in full all accrued and unpaid interest at the conclusion of the 20 consecutive Interest Payment Periods, and such failure continues for 30 days, an Event of Default that gives rise to acceleration of principal and interest on the Notes will occur under the Indenture.

During any Optional Deferral Period, interest on the Notes will continue to accrue at the then-applicable interest rate on the Notes. In addition, during any Optional Deferral Period, interest on the deferred interest (“Compound Interest”) will accrue at the then-applicable interest rate on the Notes, compounded semi-annually, to the extent permitted by applicable law. No interest will be due and payable on the Notes until the end of the Optional Deferral Period except upon a redemption of the Notes during the Optional Deferral Period. The Interest Payment Date falling immediately after the last day of an Optional Deferral Period shall not be deemed to fall on a day during such Optional Deferral Period.

No interest will be due or payable on the Notes during any such Optional Deferral Period, except upon a redemption of any Notes on any redemption date during such Optional Deferral Period (in which case all accrued and unpaid interest (including, to the extent permitted by applicable law, any Compound Interest) on the Notes to be redeemed to, but excluding, such redemption date will be due and payable on such redemption date), or unless

S-20

the principal of and interest on the Notes shall have been declared due and payable as the result of an Event of Default with respect to the Notes (in which case all accrued and unpaid interest, including, to the extent permitted by applicable law, any Compound Interest, on the Notes shall become due and payable).

All references in the Notes and, insofar as relates to the Notes, the Indenture, to “interest” on the Notes shall be deemed to include any such deferred interest and, to the extent permitted by applicable law, any Compound Interest, unless otherwise expressly stated or the context otherwise requires.

Before the end of any Optional Deferral Period that is shorter than 20 consecutive Interest Payment Periods, the Issuers may elect, at their option, to extend such Optional Deferral Period, so long as the entire Optional Deferral Period does not exceed 20 consecutive Interest Payment Periods or extend beyond the Stated Maturity of the Notes. The Issuers may also elect, at their option, to shorten the length of any Optional Deferral Period. No Optional Deferral Period (including as extended or shortened) may end on a day other than the day immediately preceding an Interest Payment Date. At the end of any Optional Deferral Period, if all amounts then due on the Notes, including all accrued and unpaid interest thereon (including, without limitation and to the extent permitted by applicable law, any deferred interest and any Compound Interest), are paid, the Issuers may elect to begin a new Optional Deferral Period; provided, however, that, without limitation of the foregoing, the Issuers may not begin a new Optional Deferral Period unless the Issuers have paid all accrued and unpaid interest on such Notes (including, without limitation and to the extent permitted by applicable law, any deferred interest and any Compound Interest) from any previous Optional Deferral Period.

During any Optional Deferral Period, Aptiv (and its majority-owned subsidiaries, as applicable) will not do any of the following (subject to the exceptions set forth in the next succeeding paragraph):

However, during an Optional Deferral Period, the exceptions will permit (a) distributions or other payments to Aptiv or any direct or indirect subsidiary of Aptiv; (b) purchases, redemptions or other acquisitions of the Issuers’ or the Guarantor’s Share Capital in connection with any employment contract, incentive plan, benefit plan or other similar arrangement with or for the benefit of employees, officers, directors, agents, consultants or a share purchase, dividend reinvestment or similar plan, or the satisfaction of the Issuers’ obligations pursuant to any contract or security outstanding on the date that the payment of interest is deferred requiring the Issuers to purchase, redeem or acquire the Issuers’ or the Guarantor’s Share Capital, (c) any payment, repayment, redemption, purchase, acquisition or declaration of a dividend as a result of any reclassification of the Issuers’ or the Guarantor’s Share Capital or the exchange or conversion of all or a portion of one class or series of the Issuers’ or the Guarantor’s Share Capital for another class or series of the Issuers’ or the Guarantor’s Share Capital, (d) the purchase of fractional interests in shares of the Issuers’ or the Guarantor’s Share Capital pursuant to the conversion or exchange provisions of such Share Capital or the security being converted or exchanged or in connection with the settlement of share purchase contracts, (e) dividends, payments or distributions payable in shares of the Issuers’ or the Guarantor’s Share Capital (or rights to acquire the Issuers’ or the Guarantor’s Share Capital), or purchases, redemptions or acquisitions of the Issuers’ or the Guarantor’s Share Capital in connection with the issuance or exchange of the Issuers’ or the Guarantor’s Share Capital (or of securities convertible into or exchangeable for shares of the Issuers’ or the Guarantor’s Share Capital) and distributions in connection with the

S-21

settlement of share purchase contracts outstanding on the date that the payment of interest is deferred, (f) redemptions, exchanges, acquisitions or repurchases of, or with respect to, any rights outstanding under any employment contract, incentive plan, benefit plan or similar arrangement of the Issuers or the Issuers’ subsidiaries or in connection with a dividend reinvestment or share purchase plan, (g) implementing a shareholder rights plan, or issuing rights, shares or other property under such plan, or any redemption, repurchase or acquisition of any such rights pursuant thereto, (h) settling conversion of any convertible notes that rank equally with the Notes or (i) payments under any preferred trust securities or subordinated notes, or any guarantee thereof, executed and delivered by the Issuers or any of the Issuers’ majority-owned subsidiaries, in each case that rank equal in right of payment to the Notes with respect to which the Issuers have elected to defer the payment of interest, or the related guarantee (as the case may be), so long as the amount of payments made on account of such securities or guarantees is paid on all such securities and guarantees then outstanding on a pro rata basis in proportion to the full payment to which each series of such securities and guarantees is then entitled if paid in full.

The Issuers will give The Depository Trust Company (“DTC”), the Holders of the Notes, the Trustee and the Registrar and Paying Agent written notice of the Issuers’ election of, or any shortening or extension of, an Optional Deferral Period at least 15 Business Days prior to the earlier of (1) each next succeeding Interest Payment Date or (2) the date upon which the Issuers are required to give notice to any applicable self-regulatory organization or to Holders of the Notes of the next succeeding Interest Payment Date or the Regular Record Date therefor. The record date for the payment of deferred interest and, to the extent permitted by applicable law, any Compound Interest payable on the Interest Payment Date immediately following the last day of an Optional Deferral Period will be the Regular Record Date with respect to such Interest Payment Date.

“Share Capital” means (i) in the case of a corporation or a company, corporate stock or shares; (ii) in the case of an association or business entity, any and all shares, interests, participations, rights or other equivalents (however designated) of corporate stock or shares; (iii) in the case of a partnership or limited liability company, partnership or membership interests (whether general or limited); and (iv) any other interest or participation that confers on a person the right to receive a share of the profits and losses of, or distributions of assets of, the issuing person.

“Interest Payment Period” means the semi-annual period from, and including, an Interest Payment Date to, but excluding, the next succeeding Interest Payment Date, except for the first interest payment period, which shall be the period from, and including,    , 2024 to, but excluding,     , 2025.

Indenture May Be Used For Future Issuances

The Issuers 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” number 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. The Issuers may also issue notes of different series under the Indenture from time to time.

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.

S-22

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.

Redemption

Optional Redemption

The Issuers may redeem the Notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest to, but excluding, the redemption date (i) on any day in the period commencing on the date falling 90 days prior to the first Reset Date and ending on and including the first Reset Date and (ii) after the first Reset Date, on any Interest Payment Date.

Redemption Following a Rating Agency Event

The Issuers may, at their option, redeem the Notes, in whole but not in part, at 102% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest to, but excluding, the redemption date, at any time within 120 days after the occurrence of a Rating Agency Event.

A “Rating Agency Event” means, as of any date, a change, clarification or amendment in the methodology in assigning equity credit to securities such as the Notes published by any nationally recognized statistical rating organization within the meaning of Section 3(a)(62) of the Exchange Act (or any successor provision thereto) that then publishes a rating for Aptiv (together with any successor thereto, a “Rating Agency”), (a) as such methodology was in effect on the date of this prospectus supplement, in the case of any rating agency that published a rating for Aptiv as of the date of this prospectus supplement, or (b) as such methodology was in effect on the date such rating agency first published a rating for Aptiv, in the case of any rating agency that first publishes a rating for Aptiv after the date of this prospectus supplement (in the case of either clause (a) or (b), the “Current Methodology”), that results in (i) any shortening of the length of time for which a particular level of equity credit pertaining to the Notes by such rating agency would have been in effect had the Current Methodology not been changed, clarified or amended or (ii) a lower equity credit (including up to a lesser amount) being assigned by such rating agency to the Notes as of the date of such change, clarification or amendment than the equity credit that would have been assigned to the Notes by such rating agency had the Current Methodology not been changed, clarified or amended.

Tax Redemption

Redemption Following a Tax Event

The Issuers may, at their option, redeem the Notes, in whole but not in part, at the redemption price equal to the sum of: (1) 100% of the principal amount of the Notes being redeemed plus (2) accrued and unpaid interest to, but excluding, the Tax Event redemption date. In such case, the Issuers will deliver a notice of redemption specifying the tax event redemption date within 120 days after the occurrence of a Tax Event.

A “Tax Event” means that the Issuers have received a written opinion of a nationally recognized accounting firm or counsel experienced in such matters to the effect that, as a result of:

S-23

which amendment, clarification or change is effective or the administrative action is taken or judicial decision, interpretation or pronouncement is issued or threatened challenge is asserted or becomes publicly-known after the date of this prospectus supplement, there is more than an insubstantial risk that interest payable by the Issuers on the Notes is not deductible, or within 90 days would not be deductible, in whole or in part, by the Issuers for income tax purposes in a Relevant Taxing Jurisdiction.

A “Relevant Taxing Jurisdiction” means Ireland or any other jurisdiction in which either of the Issuers is or becomes incorporated, organized, or otherwise resident for tax purposes after the date of this prospectus supplement, including any political subdivision or taxing authority or agency thereof or therein.

Redemption Following a Change in Tax Law Relating to Obligation to Pay Additional Amounts

The Issuers may, at their option, redeem the Notes in whole but not in part, 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 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 the Issuers or the Guarantor 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.

S-24

Prior to giving the notice of tax redemption, the Issuers 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.

Redemption Procedures

Notice of any 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 Issuers partially redeem the Notes, the Registrar and Paying Agent, subject to the procedures of DTC, will select the Notes to be redeemed on a pro rata basis, by lot or by such other method in accordance with the procedures of DTC, although no Note less than $200,000 in original principal amount will be redeemed in part. If the Issuers redeem 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 of such Notes called for redemption so long as the Issuers have 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, 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.

Tax Treatment

On the Issue Date, all or a portion of the proceeds of the offering of the Notes will be borrowed by AGFDAC 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 AGFDAC 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 AGFDAC and Aptiv have the right to change the foregoing allocations between AGFDAC 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.

S-25

Each holder (and beneficial owner) of the Notes will, by accepting any Notes (or a beneficial interest therein), be deemed to have agreed that such holder (or beneficial owner) intends that the Notes constitute indebtedness of the Issuers, and will treat the Notes as indebtedness of Issuers, for (i) United States federal, state and local tax purposes and (ii) tax purposes in or with respect to each Relevant Taxing Jurisdiction.

Note Guarantee

The Guarantor, as a primary obligor and not merely as a surety, will irrevocably and unconditionally guarantee on a subordinated 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, 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 Guarantee is unsecured and ranks junior and subordinate in right of payment to the Senior Indebtedness of each of the Issuers and the Guarantor, respectively. See “—Subordination” below. All of Aptiv’s currently outstanding notes and Aptiv’s borrowings under its credit agreements are senior obligations of each of the Issuers and the Guarantor and rank senior in right of payment to the Notes.

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 June 30, 2024, after giving effect to the Transactions, the Issuers and the Guarantor would have had total indebtedness of $  million, of which $  million would rank senior in right of payment to the Notes.

S-26

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 $23,236 million and total liabilities of $5,927 million, including total debt of $34 million, or 94% of our total assets and 46% of our total liabilities, as of June 30, 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 may also be secured.

The Notes will rank equal in right of payment to all future subordinated obligations of each of the Issuers and the Guarantor.

Subordination

The Notes will be subordinated in right of payment to the prior payment in full of all the Issuers’ and the Guarantor’s Senior Indebtedness. This means that upon:

the holders of all such Senior Indebtedness will be entitled to receive:

before the Holders of the Notes are entitled to receive any payment. So long as any of the events in clauses (a), (b), or (c) above has occurred and is continuing, any amounts payable or assets distributable on the Notes will instead be paid or distributed, as the case may be, directly to the holders of Senior Indebtedness to the extent necessary to pay, in the case of clause (a) above, all amounts due or to become due upon all such Senior Indebtedness, or, in the case of clauses (b) and (c) above, all amounts due on all such Senior Indebtedness, and, if any such payment or distribution is received by the Trustee under the Indenture or the Holders of any of the Notes before all Senior Indebtedness due and to become due or due, as applicable, is paid, such payment or distribution must be paid over to the holders of the unpaid Senior Indebtedness. Subject to paying the Senior Indebtedness due and to become due in the case of clause (a) or the Senior Indebtedness due in the case of clauses (b) and (c), the Holders of the Notes will be subrogated to the rights of the holders of such Senior Indebtedness to receive payments or distributions of assets of the Issuers or the Guarantor applicable to such Senior Indebtedness until the Notes are paid in full.

S-27

Due to the subordination of the Notes, if assets of the Issuers or the Guarantor are distributed upon its dissolution, winding-up, liquidation or reorganization, holders of Senior Indebtedness and other indebtedness and obligations that are not equal or junior to the Notes in right of payment will likely recover more, ratably, than Holders of the Notes, and it is possible that no payments will be made to the Holders of the Notes. The subordination provisions described above will cease to apply in the event of satisfaction and discharge of the Notes as described under “—Satisfaction and Discharge.”

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 (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 the Issuers or the Guarantor is incorporated, organized, engaged in business or otherwise resident for tax purposes, or any other 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) 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-28

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.

All references in this prospectus supplement and the accompanying prospectus, other than under “—Defeasance” and “—Satisfaction and Discharge” in this prospectus supplement, to the payment of the principal or interest, if any, on or the net proceeds received on the sale or exchange of, any Notes or any payment made under the Note Guarantee shall be deemed to include Additional Amounts to the extent that, in that context, Additional Amounts are, were or would be payable.

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.

S-29

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:

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.

S-30

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 clause (3) will not constitute an Event of Default with respect to any Notes until the Trustee notifies the Issuers or the Holders of at least 33% in principal amount of the outstanding Notes and all other notes issued under the Indenture affected thereby notify the Issuers and the Trustee of the default and the Issuers do not cure such default within the time specified in clause (3) hereof after receipt of such notice.

If an Event of Default (other than an Event of Default described in clause (3) above) occurs and is continuing, the Trustee (at the direction of the Holders) or the Holders of at least 33% 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 due and payable. Upon such a declaration, such principal and interest will be due and payable immediately. This right does not apply if an Event of Default described in clause (3) above occurs. If one of the Events of Default described in clause (3) above occurs and is continuing, neither the Trustee nor the Holders of the Notes will be entitled to declare the principal amount of all Notes, together with accrued and unpaid interest thereon, to be due and payable immediately. 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:

S-31

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 notice of such Default is given to a Trust Officer of 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 written notice of it is received by a Trust Officer of 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, 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 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:

S-32

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

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 and 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.

S-33

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 and the Registrar and Paying Agent and, in the case of clause (2), the Issuers deposit with the Registrar and Paying Agent funds or U.S. 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.

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, 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 U.S. 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).

S-34

Book-Entry, Delivery and Form

The Notes initially will be represented by one or more permanent global certificates in definitive, fully registered form (the “Global Notes”). The Global Notes will be deposited upon issuance with DTC, and registered in the name of a nominee of DTC in the form of a global certificate. DTC has advised the Issuers that pursuant to procedures established by it (i) upon the issuance of the Global Notes, DTC or its custodian will credit, on its internal system, the principal amount at maturity of the individual beneficial interests represented by such Global Notes to the respective accounts of persons who have accounts with such depositary and (ii) ownership of beneficial interests in the Global Notes will be shown on, and the transfer of such ownership will be effected only through, records maintained by DTC or its nominee (with respect to interests of participants) and the records of participants (with respect to interests of persons other than participants). Ownership of beneficial interests in the Global Notes will be limited to persons who have accounts with DTC (“participants”) or persons who hold interests through participants. Holders may hold their interests in the Global Notes directly through DTC if they are participants in such system, or indirectly through organizations that are participants in such system.

So long as DTC, or its nominee, is the registered owner or Holder of the Notes, DTC or such nominee, as the case may be, will be considered the sole owner or Holder of the Notes represented by such Global Notes for all purposes under the indenture governing the Notes. No beneficial owner of an interest in the Global Notes will be able to transfer that interest except in accordance with DTC’s procedures, in addition to those provided for under the indenture with respect to the Notes.

Payments of the principal of, premium, if any, and interest (including additional interest) on, the Global Notes will be made to DTC or its nominee, as the case may be, as the registered owner of the Global Notes. None of the Issuers, the Trustee or any paying agent under the indenture governing the Notes will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the Global Notes or for maintaining, supervising or reviewing any records relating to such beneficial ownership interest.

DTC has advised the Issuers that its present practice is, upon receipt of any payment of principal, premium, if any, and interest (including additional interest) on the Global Notes, to credit immediately participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the Global Notes as shown on the records of DTC. Payments by participants to owners of beneficial interests in the Global Notes held through such participants will be governed by standing instructions and customary practice, as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. Such payments will be the responsibility of such participants.

Transfers between participants in DTC will be effected in the ordinary way through DTC’s same-day funds system in accordance with DTC rules and will be settled in same-day funds. If a Holder requires physical delivery of a certificated security for any reason, including to sell Notes to persons in states which require physical delivery of the Notes, or to pledge such securities, such Holder must transfer its interest in a Global Note, in accordance with the normal procedures of DTC and with the procedures set forth in the indenture governing the Notes.

DTC has advised the Issuers that it will take any action permitted to be taken by a Holder of Notes, including the presentation of Notes for exchange as described below, only at the direction of one or more participants to whose account the DTC interests in the Global Notes are credited and only in respect of such portion of the aggregate principal amount of Notes as to which such participant or participants has or have given such direction. However, if there is an event of default under the indenture governing the Notes, DTC will exchange the Global Notes for certificated securities, which it will distribute to its participants.

DTC has advised the Issuers as follows: DTC is a limited purpose trust company organized under the laws of the State of New York, a member of the Federal Reserve System, a “clearing corporation” within the meaning

S-35

of the Uniform Commercial Code and a “Clearing Agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC was created to hold securities for its participants and facilitate the clearance and settlement of securities transactions between participants through electronic book-entry changes in accounts of its participants, thereby eliminating the need for physical movement of certificates. Participants include securities brokers and dealers, banks, trust companies and clearing corporations and certain other organizations. Indirect access to the DTC system is available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly (“indirect participants”).

Although DTC has agreed to the foregoing procedures in order to facilitate transfers of interests in the Global Note among participants of DTC, it is under no obligation to perform such procedures, and such procedures may be discontinued at any time. Neither the Issuers nor the trustee will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

Clearstream. Clearstream is incorporated under the laws of Luxembourg as a professional depositary. 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 establishment of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Monetary Institute. 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 Notes held beneficially through Clearstream will be credited to cash accounts of Clearstream Participants in accordance with its rules and procedures to the extent received by DTC for Clearstream.

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 markets in several countries. Euroclear is operated by Euroclear Bank SA/NV (the “Euroclear Operator”), under contract with Euroclear Clearance Systems S.C., a Belgian cooperative corporation (the “Cooperative”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not the Cooperative. The Cooperative establishes policy for Euroclear on behalf of Euroclear Participants. 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 Euroclear Operator is regulated and examined by the Belgian Banking Commission.

Links have been established among DTC, Clearstream and Euroclear to facilitate the initial issuance of the Notes sold outside of the United States and cross-market transfers of the Notes associated with secondary market trading.

S-36

Although DTC, Clearstream and Euroclear have agreed to the procedures provided below in order to facilitate transfers, they are under no obligation to perform these procedures, and these procedures may be modified or discontinued at any time.

Clearstream and Euroclear will record the ownership interests of their participants in much the same way as DTC, and DTC will record the total ownership of each of the U.S. agents of Clearstream and Euroclear, as participants in DTC. When Notes are to be transferred from the account of a DTC participant to the account of a Clearstream participant or a Euroclear participant, the purchaser must send instructions to Clearstream or Euroclear through a participant at least one day prior to settlement. Clearstream or Euroclear, as the case may be, will instruct its U.S. agent to receive Notes against payment. After settlement, Clearstream or Euroclear will credit its participant’s account. Credit for the Notes will appear on the next day (European time).

Because settlement is taking place during New York business hours, DTC participants will be able to employ their usual procedures for sending Notes to the relevant U.S. agent acting for the benefit of Clearstream or Euroclear participants. The sale proceeds will be available to the DTC seller on the settlement date. As a result, to the DTC participant, a cross-market transaction will settle no differently than a trade between two DTC participants.

When a Clearstream or Euroclear participant wishes to transfer Notes to a DTC participant, the seller will be required to send instructions to Clearstream or Euroclear through a participant at least one business day prior to settlement. In these cases, Clearstream or Euroclear will instruct its U.S. agent to transfer these Notes against payment for them. The payment will then be reflected in the account of the Clearstream or Euroclear participant the following day, with the proceeds back valued to the value date, which would be the preceding day, when settlement occurs in New York. If settlement is not completed on the intended value date, that is, the trade fails, proceeds credited to the Clearstream or Euroclear participant’s account will instead be valued as of the actual settlement date.

You should be aware that you will only be able to make and receive deliveries, payments and other communications involving the Notes through Clearstream and Euroclear on the days when those clearing 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.

Certificated Securities

A Global Note is exchangeable for certificated securities if:

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 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 Issuers (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-41

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-42

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:

Classification of the Notes

The determination of whether a security should be classified as indebtedness or equity for U.S. federal income tax purposes requires a judgment based on all relevant facts and circumstances. There is no statutory, judicial or administrative authority that directly addresses the U.S. federal income tax treatment of securities

S-43

similar to the notes. Under current law, and based on the facts contained in this prospectus supplement, the terms of the indenture and the Notes, and certain assumptions and representations, the Notes should be classified for U.S. federal income tax purposes as indebtedness (although there is no controlling authority directly on point with respect to the treatment of the Notes and interest thereon). However, no rulings have been or will be sought from the IRS with respect to the classification of the Notes as indebtedness or the U.S. federal income tax consequences of the acquisition, ownership or disposition of the Notes. Accordingly, we cannot assure holders that the IRS will not challenge the classification of the Notes as indebtedness for U.S. federal income tax purposes or that a court would not sustain such a challenge. If the IRS were to successfully challenge the classification of the Notes as indebtedness, interest payments on the Notes could be treated for U.S. federal income tax purposes as dividends to the extent of our current or accumulated earnings and profits. We agree, and by acquiring an interest in a Note, each holder of a Note will agree, to treat the Notes as indebtedness for U.S. federal income tax purposes, and the remainder of this discussion assumes such treatment. U.S. Holders should consult their tax advisors regarding the tax consequences that would apply if the Notes are not treated as indebtedness for U.S. federal income tax purposes.

Payments of Interest

Subject to the discussion immediately below, stated interest paid on a 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.

The Notes should be treated as “variable rate debt instruments” for U.S. federal income tax purposes. If the Notes were not treated as variable rate debt instruments, then the Notes would be treated as “contingent payment debt instruments,” in which case U.S. Holders could be required to accrue interest income on the Notes in excess of stated interest and would be required to treat as ordinary income, rather than as capital gain, any income realized on a taxable disposition of the Notes. Applicable Treasury Regulations set forth rules to determine whether a variable rate debt instrument is treated as issued with original issue discount for U.S. federal income tax purposes (“OID”). Based on the application of these Treasury Regulations and the expected pricing terms of the Notes, we do not expect the pricing of the Notes to result in the Notes as being treated as issued with OID. We have the option under certain circumstances to defer payments of stated interest on the Notes. Under the Treasury Regulations relating to OID, a debt instrument is deemed to be issued with OID if there is more than a “remote” contingency that periodic stated interest payments due on the instrument will not be timely paid. We believe the likelihood of our exercising the option to defer payment of stated interest on the Notes is remote within the meaning of the Treasury Regulations in part because our exercise of the option to defer payments of stated interest on the Notes would generally prevent us from:

Similarly, if certain circumstances occur (see “Description of the Notes—Redemption—Redemption Following a Rating Agency Event” and “—Additional Amounts”), we may be obligated to pay amounts in excess of stated principal on the Notes. If there is only a remote likelihood that such payments will be made, such excess payments will not affect the amount of interest income that a U.S. Holder recognizes. We believe the likelihood that we will make any such payments is remote within the meaning of the Treasury Regulations. If the possibility that we would be required to make such payments were determined not to be remote, the Notes could be treated

S-44

as “contingent payment debt instruments,” in which case, as described above, U.S. Holders could be required to accrue interest income on the Notes in excess of stated interest and would be required to treat as ordinary income, rather than as capital gain, any income realized on a taxable disposition of the Notes.

The meaning of the term “remote” in the Treasury Regulations has not yet been addressed in any rulings or other guidance by the IRS or any court. Our determination that the contingencies described above are remote is binding on a U.S. Holder unless such holder discloses its contrary position in the manner required by applicable Treasury Regulations. Our determination is not, however, binding on the IRS. There can be no assurance that the IRS or a court will agree with these positions.

The remainder of this discussion assumes the Notes will not be treated as issued with OID or as contingent payment debt instruments.

Exercise of Deferral Option

Under the Treasury Regulations, if we exercise our option to defer the payment of interest on the Notes, the Notes will be treated as if they had been redeemed and reissued solely for OID purposes. In that event, all remaining interest payments on the Notes (including interest on deferred interest) would be treated as OID, which U.S. Holders would be required to accrue and include in taxable income, without regard to such U.S. Holders’ regular method of accounting for U.S. federal income tax purposes. The amount of OID income includible in such U.S. Holders’ taxable income would be determined on the basis of a constant yield method over the remaining term of the Notes, and the actual receipt of future payments of stated interest on the Notes would no longer be separately reported as taxable income. The total amount of OID that would accrue during the deferral period would be approximately equal to the amount of the cash payment due immediately following the end of that period. A U.S. Holder’s adjusted tax basis in its Notes would be increased by any OID included in the U.S. Holder’s income and decreased by the actual receipt of cash interest payments on the Notes.

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 Designated Activity Company 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 Designated Activity Company 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 Designated Activity Company and Aptiv have the right to change the allocation of the Notes between Aptiv Global Financing Designated Activity Company 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 Designated Activity Company and Aptiv than the initial allocation with respect to the outstanding Notes). Aptiv Global Financing Designated Activity Company 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.

S-45

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 (generally, its cost). For these purposes, the amount realized does not include any amount attributable to accrued stated interest. Amounts attributable to accrued stated interest and not previously included in income are treated as interest as described under “—Payments of Interest” above. If the Notes are treated as having been issued or reissued with OID, such adjusted tax basis will also be increased by the amount of any OID previously included in a U.S. Holder’s gross income with respect to the Notes and decreased by any payments received on the Notes since and including the date that the Notes were deemed to be issued with OID.

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.

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-46

UNDERWRITING (CONFLICTS OF INTEREST)

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 and the Guarantor 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 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 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. Stabilizing transactions involve bids to purchase the Notes in the open market for the purpose of pegging, fixing

S-47

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.

Extended Settlement

The Issuers expect that the delivery of the Notes will be made against payment therefor on or about     , 2025, 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.

Conflicts of Interest

Certain of the underwriters or their affiliates are lenders under the Bridge Credit Agreement and/or may own 2025 Notes. As a result of the intended use of net proceeds of this offering to redeem in full the 2025 Notes and, together with cash on hand, to repay the loans outstanding under the Bridge Credit Agreement, such underwriters or their affiliates may receive at least 5% of the net proceeds of this offering. The receipt of at least 5% of the net proceeds of this offering by any underwriter or its affiliates would be considered a “conflict of interest” under FINRA Rule 5121 for such underwriters. Consequently, this offering will be conducted in accordance with the applicable requirements of FINRA Rule 5121. Rule 5121 requires prominent disclosure of the nature of the conflict of interest in the prospectus supplement for the public offering. Pursuant to Rule 5121(a)(1)(C), the appointment of a qualified independent underwriter is not necessary in connection with this offering as the securities offered are investment grade rated.

Other Relationships

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 facilities and receive customary compensation in connection therewith. The credit facilities were negotiated on an arm’s length basis and contain terms pursuant to which the lenders receive customary fees. In addition, each of the underwriters are acting as underwriters for the Concurrent Offering. Accordingly, each of the underwriters or their affiliates may receive underwriting commissions from the Concurrent Offering. Additionally, certain of the underwriters or their affiliates are lenders under the Bridge Credit Agreement and/or may own 2025 Notes. As a result of the intended use of net proceeds of this offering to redeem in full the 2025 Notes and, together with cash on hand, to repay the loans outstanding under the Bridge Credit Agreement, such underwriters or their affiliates may receive a portion of the net proceeds of 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

S-48

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.

Consequently, no key information document required by Regulation (EU) 1286/2014 as it forms part of domestic law by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the Notes or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation. This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of the Notes in the UK will be made pursuant to an exemption under the UK Prospectus Regulation and the FSMA from the requirement to publish a prospectus for offers of the Notes. Neither this prospectus supplement nor the accompanying prospectus is a prospectus for the purposes of the UK Prospectus Regulation or the FSMA.

In the UK, the communication of this prospectus supplement, the accompanying prospectus, any related free writing prospectus and any other document or materials relating to the issue of the Notes offered hereby is not being made, and such documents and/or materials have not been approved, by an authorized person for the purposes of section 21 of the FSMA.

In the United Kingdom, the Notes offered hereby are only available to, and any investment or investment activity to which this prospectus supplement, the accompanying prospectus and any related free writing prospectus relates will be engaged in only with, relevant persons. Any person in the United Kingdom that is not a relevant person should not act or rely on this prospectus supplement, the accompanying prospectus or any related free writing prospectus or any of their contents. The Notes are not being offered to the public in the UK.

Canada

The Notes may be sold in Canada only to purchasers purchasing, or deemed to be purchasing, as principal that are accredited investors, as defined in National Instrument 45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument 31-103

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, 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; 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 Reports on Form 10-Q for the quarters ended March 31 and June 30, 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. 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.

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.

5

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 June 30, 2024, there were 266,704,200 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.

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.

6

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 10 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 June 30, 2024, we have no preferred shares issued and outstanding. The Board of Directors has the authority to issue the preferred shares in one or 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.

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.

Listing

Our ordinary shares are listed on the NYSE under the symbol “APTV.” We will describe the listing of any series of preferred shares in the prospectus supplement for such series.

Transfer Agent and Registrar

The U.S. transfer agent and registrar for the ordinary shares is Computershare Trust Company, N.A. The U.S. transfer agent and registrar’s address is 250 Royall Street, Canton, MA 02021, Attention: Client Administration. Computershare Investor Services (Jersey) Limited is the transfer agent and registrar for the ordinary shares in Jersey and its address is 13 Castle Street, St Helier, Jersey JE1 1ES.

The transfer agent for each series of preferred shares will be described in the prospectus supplement for such series.

DESCRIPTION OF DEBT SECURITIES AND GUARANTEES OF DEBT SECURITIES

Aptiv PLC (“Aptiv PLC”), Aptiv Corporation (“Aptiv Corp.”) or Aptiv Global Financing Designated Activity Company (formerly known as Aptiv Global Financing Limited) (“AGFDAC”) may offer debt securities, subject to the consent of the Jersey Financial Services Commission, if required. This prospectus describes certain general terms and provisions of the debt securities. When Aptiv PLC, Aptiv Corp. or AGFDAC offer to sell a particular series of debt securities, the specific terms for the securities will be set forth in a supplement to this prospectus. The prospectus supplement will also indicate whether the general terms and provisions described in this prospectus apply to a particular series of debt securities.

Aptiv PLC’s senior debt securities would be issued under a senior indenture dated as of March 10, 2015, as supplemented, among Aptiv PLC, the guarantors party thereto, Wilmington Trust, National Association, as trustee (the “Trustee”) and Deutsche Bank Trust Company Americas, as registrar, paying agent and authenticating agent (the “Registrar and Paying Agent”). Aptiv PLC’s subordinated indentures would be issued under a subordinated indenture among Aptiv PLC, the guarantors party thereto, the Trustee and the Registrar and Paying Agent.

Aptiv Corp.’s senior debt securities would be issued under a senior indenture dated as of February 14, 2013, as supplemented, among Aptiv Corp., Aptiv PLC, as a guarantor, the other guarantors party thereto, the Trustee and the Registrar and Paying Agent. Aptiv Corp.’s subordinated indentures would be issued under a subordinated indenture among Aptiv Corp., Aptiv PLC, as a guarantor, the other guarantors party thereto, the Trustee and the Registrar and Paying Agent.

AGFDAC’s senior debt securities would be issued under a senior indenture among AGFDAC, Aptiv PLC, as a guarantor, the other guarantors party thereto, the Trustee and the Registrar and Paying Agent.

This prospectus refers to each of Aptiv PLC’s senior indenture, Aptiv PLC’s subordinated indenture, Aptiv Corp.’s senior indenture, Aptiv Corp.’s subordinated indenture and AGFDAC’s senior indenture individually as the “indenture” and collectively as the “indentures.” We refer to Aptiv PLC’s senior indenture, Aptiv Corp.’s senior indenture and AGFDAC’s senior indenture collectively as the “senior indentures” and each individually as a “senior indenture.” We refer to Aptiv PLC’s subordinated indenture and Aptiv Corp.’s subordinated indenture collectively as the “subordinated indentures” and each individually as a “subordinated indenture.”

We have summarized certain terms and provisions of the indentures. The summary is not complete. The indentures have been filed as exhibits to the registration statement of which this prospectus forms a part, which we have filed with the SEC. You should read the indentures for the provisions which may be important to you. The indentures are subject to and governed by the Trust Indenture Act of 1939, as amended. The senior indentures and the subordinated indentures are substantially identical, except for the provisions relating to subordination. See “—Subordinated Debt.”

We, Aptiv Corp. or AGFDAC may issue debt securities up to an aggregate principal amount as we, Aptiv Corp. or AGFDAC may authorize from time to time. The prospectus supplement will describe the terms of any debt securities being offered, including:

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 AGFDAC 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.

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.

10

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:

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 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.

13

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:

14

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 AGFDAC 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 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

15

trust preferred security or unit agreement. We understand that under existing industry practices, if Aptiv PLC, Aptiv Corp. or AGFDAC 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., AGFDAC, the trustees, the warrant agents, the unit agents or any other agent of Aptiv PLC, Aptiv Corp. or AGFDAC, 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 Exchange Act, and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, Aptiv PLC, Aptiv Corp. or AGFDAC, 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 AGFDAC. 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.
