(To Prospectus dated October 26, 2018)

10,000,000 Shares

Aptiv PLC

    % Series A Mandatory Convertible Preferred Shares

Aptiv PLC is offering 10,000,000 of our     % Series A Mandatory Convertible Preferred Shares, par value $0.01 per share (the “Mandatory Convertible Preferred Shares”).

Dividends on our Mandatory Convertible Preferred Shares will be payable on a cumulative basis when, as and if declared by our board of directors, or an authorized committee of our board of directors, at an annual rate of     % of the liquidation preference of $100.00 per share. We may pay declared dividends in cash or, subject to certain limitations, in our ordinary shares, or in any combination of cash and ordinary shares, on March 15, June 15, September 15 and December 15 of each year, commencing on September 15, 2020 and ending on, and including, June 15, 2023. Each of our Mandatory Convertible Preferred Shares has a liquidation preference of $100.00.

Each of our Mandatory Convertible Preferred Shares will automatically convert on the second business day immediately following the last trading day (as defined herein) of the Settlement Period (as defined herein) into between                and                 of our ordinary shares (respectively, the “Minimum Conversion Rate” and “Maximum Conversion Rate”), each subject to anti-dilution adjustments. The number of our ordinary shares issuable on conversion of the Mandatory Convertible Preferred Shares will be determined based on the Average VWAP (as defined herein) per ordinary share over the 20 consecutive trading day period (the “Settlement Period”) commencing on, and including, the 21st scheduled trading day immediately preceding June 15, 2023. At any time prior to June 15, 2023, holders may elect to convert each Mandatory Convertible Preferred Share into ordinary shares at the Minimum Conversion Rate of our ordinary shares per Mandatory Convertible Preferred Share. If you elect to convert any Mandatory Convertible Preferred Shares during a specified period beginning on the effective date of a Fundamental Change (as defined herein), such Mandatory Convertible Preferred Shares will be converted into ordinary shares at the Fundamental Change Conversion Rate (as defined herein), and you will also be entitled to receive a Fundamental Change Dividend Make-whole Amount and Accumulated Dividend Amount (each as defined herein).

Concurrently with this offering of Mandatory Convertible Preferred Shares and pursuant to a separate prospectus supplement, we are offering $1.0 billion of our ordinary shares (the “ordinary shares”) to the public (the “Concurrent Ordinary Shares Offering”) (or $1.15 billion if the underwriters for the Concurrent Ordinary Shares Offering exercise in full their option to purchase additional ordinary shares). The closing of this offering of Mandatory Convertible Preferred Shares is not contingent upon the closing of the Concurrent Ordinary Shares Offering, and the closing of the Concurrent Ordinary Shares Offering is not contingent upon the closing of this offering of Mandatory Convertible Preferred Shares. The Concurrent Ordinary Shares Offering is being made by means of a separate prospectus supplement and accompanying prospectus, and nothing contained in this prospectus supplement shall constitute an offer to sell or a solicitation of an offer to buy any securities being offered in the Concurrent Ordinary Shares Offering. See “Concurrent Ordinary Shares Offering.”

Prior to this offering, there has been no public market for our Mandatory Convertible Preferred Shares. We intend to apply to list the Mandatory Convertible Preferred Shares on the New York Stock Exchange (the “NYSE”) under the symbol “APTV PR A.” Our ordinary shares are listed on the NYSE under the symbol “APTV.” The closing price of our ordinary shares on the NYSE on June 5, 2020 was $85.85 per share.

Investing in our Mandatory Convertible Preferred Shares involves a high degree of risk. Before making an investment decision, you should carefully consider the risks described under “Risk Factors” beginning on page S-18 of this prospectus supplement, page 5 of the accompanying prospectus, under Item 1A in our Annual Report on Form 10-K for the year ended December 31, 2019 and under Item 1A in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020, which have been filed with the Securities and Exchange Commission and are incorporated by reference in this prospectus supplement and the accompanying prospectus.

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 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; uncertainties posed by the novel coronavirus (COVID-19) pandemic and the difficulty in predicting its future course and its impact on the global economy and our future operations; fluctuations in interest rates and foreign currency exchange rates; the cyclical nature of global automotive sales and production; the potential disruptions in the supply of and changes in the competitive environment for raw material integral to our products; 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 and its predecessor agreement, the North American Free Trade Agreement; our ability to integrate and realize the expected benefits of recent transactions; our ability to attract, motivate and/or retain key executives; our ability to avoid or continue to operate during a strike, or partial work stoppage or slow down by any of our unionized employees or those of our principal customers, and our ability to attract and retain customers. Additional factors are discussed under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our filings with the Securities and Exchange Commission, including those set forth in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019 and our Quarterly Report on Form 10-Q for the three months ended March 31, 2020. 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 Mandatory Convertible Preferred Shares as well as the underlying 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 supplement to conform our prior statements to actual results or revised expectations.

RISK FACTORS

Investing in our Mandatory Convertible Preferred Shares 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 our Mandatory Convertible Preferred Shares. 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 fiscal year ended December 31, 2019 and in our Quarterly Report on Form 10-Q for the three months ended March 31, 2020 incorporated by reference in this prospectus supplement and the accompanying prospectus.

Risks Related to COVID-19

The effects of a pandemic or widespread outbreak of an illness, such as the novel coronavirus (COVID-19) pandemic, could have a material adverse effect on our business, financial condition, results of operations and cash flows.

The global spread of the COVID-19 pandemic, which originated in late 2019 and was later declared a pandemic by the World Health Organization in March 2020, has negatively impacted the global economy, disrupted supply chains and created significant volatility in global financial markets. Although we have taken decisive actions to enhance our financial flexibility and minimize the impact on our business, such as the ramping down of certain production facilities in response to customer plant closures and changes in vehicle production schedules, imposing certain travel restrictions, suspending our cash dividend, drawing down all remaining availability under our existing revolving credit facility and actively managing costs, capital spending and working capital to further strengthen our liquidity, the ultimate impact to our business continues to remain uncertain. The extent to which the COVID-19 pandemic will impact our business will depend on a number of evolving factors, including the duration and spread of the pandemic, as well as the possibility of the pandemic reoccurring, actions taken by governmental authorities to restrict certain business operations and social activity, impose travel restrictions or other actions, the impact of the pandemic on economic activity and whether recessionary conditions will persist, consumer demand and vehicle production schedules, the ability of our supply chain to deliver in a timely and cost-effective manner, the ability of our employees, manufacturing and distribution facilities to operate efficiently and effectively, the continued viability and financial stability of our customers and suppliers and future access to capital, all of which remain uncertain. To date, the COVID-19 pandemic has adversely impacted our business, financial condition, results of operations and cash flows. The adverse impacts of the pandemic have included extended work stoppages and travel restrictions at our facilities and those of our customers and suppliers, decreases in consumer demand and vehicle production schedules, disruptions to our supply chain and other resultant adverse global economic impacts, particularly those resulting from governmental “lock-down” orders for all non-essential activities in China, Europe and North America. Our total net sales during the three months ended March 31, 2020 were $3.2 billion, a decrease of 10% compared to the same period of 2019, primarily attributable to volume decreases largely resulting from the impacts of the COVID-19 pandemic. In addition, many of our largest customers have experienced vehicle production shutdowns across their global production facilities, specifically in the North American and European regions, beginning in the first quarter of 2020 and extending into the second quarter of 2020. As a result, these or any further production shutdowns, or an extended period of global and economic disruption resulting from this pandemic and its effects could have a material adverse effect on our business, financial condition, results of operations and cash flows. To the extent the COVID-19 pandemic adversely affects our business, financial condition, results of operations and cash flows, it may also have the effect of heightening many of the other risks described in this ‘‘Risk Factors’’ section, as well as those under the heading “Risk Factors” in our Annual Report on Form 10-K and in our Quarterly Report on Form 10-Q incorporated by reference in this prospectus supplement and the accompanying prospectus.

Risks Related to the Mandatory Convertible Preferred Shares and this Offering

You will bear the risk of a decline in the market price of our ordinary shares between the pricing date for the Mandatory Convertible Preferred Shares and the Mandatory Conversion Date.

The number of our ordinary shares that you will receive upon mandatory conversion of the Mandatory Convertible Preferred Shares is not fixed but instead will depend on the Applicable Market Value of our ordinary shares, which is the Average VWAP per ordinary share over the Settlement Period, which is the 20 consecutive Trading Day period beginning on, and including, the 21st Scheduled Trading Day immediately preceding June 15, 2023. The aggregate market value of the ordinary shares that you would receive upon mandatory conversion may be less than the aggregate Liquidation Preference of the Mandatory Convertible Preferred Shares. Specifically, if the Applicable Market Value of our ordinary shares is less than the Initial Price, which is calculated by dividing $100.00 by the Maximum Conversion Rate of                 ordinary shares (and initially is approximately equal to the per share public offering price of our ordinary shares in the concurrent offering of our ordinary shares (or, if such concurrent offering does not price, the closing price of our ordinary shares on June     , 2020)), the market value of our ordinary shares that you would receive upon mandatory conversion of each Mandatory Convertible Preferred Share will be less than the $100.00 liquidation preference per Mandatory Convertible Preferred Share, and an investment in the Mandatory Convertible Preferred Shares would result in a loss. Accordingly, you will bear the risk of a decline in the market price of our ordinary shares. Any such decline could be substantial.

In addition, because the number of shares delivered to you upon mandatory conversion will be based upon the Applicable Market Value, the ordinary shares you receive upon mandatory conversion may be worth less than the ordinary shares you would have received had the Applicable Market Value been equal to the VWAP per ordinary share on the Mandatory Conversion Date or the Average VWAP of our ordinary shares over a different period of days.

Purchasers of our Mandatory Convertible Preferred Shares may not realize any or all of the benefit of an increase in the market price of our ordinary shares. The opportunity for equity appreciation provided by your investment in the Mandatory Convertible Preferred Shares is less than that provided by a direct investment in our ordinary shares.

The market value of each ordinary share that you will receive upon mandatory conversion of each Mandatory Convertible Preferred Share on the Mandatory Conversion Date (assuming that all dividends on Mandatory Convertible Preferred Shares will be declared and paid in cash) will only exceed the Liquidation Preference of $100.00 per Mandatory Convertible Preferred Share if the Applicable Market Value of our ordinary shares exceeds the Threshold Appreciation Price, which is calculated by dividing $100.00 by the Minimum Conversion Rate and initially is approximately equal to $            . The Threshold Appreciation Price represents an appreciation of approximately     % over the Initial Price. If the Applicable Market Value of our ordinary shares is greater than the Threshold Appreciation Price, you will receive on the Mandatory Conversion Date approximately     % (which percentage is approximately equal to the Initial Price divided by the Threshold Appreciation Price) of the value of our ordinary shares that you would have received if you had made a direct investment in our ordinary shares on the date of this prospectus supplement. This means that the opportunity for equity appreciation provided by an investment in the Mandatory Convertible Preferred Shares is less than that provided by a direct investment in our ordinary shares.

In addition, if the market value of our ordinary shares appreciates and the Applicable Market Value of our ordinary shares is equal to or greater than the Initial Price but less than or equal to the Threshold Appreciation Price, the aggregate market value of our ordinary shares that you would receive upon mandatory conversion (assuming that all dividends on the Mandatory Convertible

S-19

Table of Contents

Preferred Shares will be declared and paid in cash) will only be equal to the aggregate Liquidation Preference of the Mandatory Convertible Preferred Shares, and you will realize no equity appreciation on our ordinary shares.

The market price of our ordinary shares has been and could remain volatile and will directly affect the market price for our Mandatory Convertible Preferred Shares.

We expect that, generally, the market price of our ordinary shares will affect the market price of our Mandatory Convertible Preferred Shares more than any other single factor. This may result in greater volatility in the market price of our Mandatory Convertible Preferred Shares than would be expected for nonconvertible preferred shares. As the price of our ordinary shares on NYSE constantly changes, it is impossible to predict whether the price of our ordinary shares will rise or fall. Our share price could materially fluctuate or decrease in response to a number of events and factors, including but not limited to: quarterly variations in operating results; operating and stock price performance of comparable companies; changes in our financial strength ratings; regulatory developments and negative publicity relating to us or our competitors. In addition, broad market and industry fluctuations may materially and adversely affect the trading price of our ordinary shares, regardless of our actual operating performance. In addition, general market conditions, including the level of, and fluctuations in, the trading prices of equities generally, could affect the price of our ordinary shares.

In addition, we expect that the market price of our Mandatory Convertible Preferred Shares will be influenced by yield and interest rates in the capital markets, the time remaining to the Mandatory Conversion Date, our creditworthiness and the occurrence of certain events affecting us that do not require an adjustment to the Fixed Conversion Rates. Fluctuations in yield rates in particular may give rise to arbitrage opportunities based upon changes in the relative values of our Mandatory Convertible Preferred Shares and our ordinary shares. Any such arbitrage could, in turn, affect the market prices of our ordinary shares and our Mandatory Convertible Preferred Shares. The market price of our ordinary shares could also be affected by possible sales of our ordinary shares by investors who view our Mandatory Convertible Preferred Shares as a more attractive means of equity participation in us and by hedging or arbitrage trading activity that we expect to develop involving our ordinary shares. This trading activity could, in turn, affect the market price of our Mandatory Convertible Preferred Shares.

Future sales of substantial amounts of our ordinary shares could affect the market price of our ordinary shares.

Future sales of substantial amounts of our ordinary shares or other securities convertible or exchangeable into our ordinary shares into the public market whether by us or any of our security holders, including ordinary shares issued and delivered pursuant to the terms of the Mandatory Convertible Preferred Shares or issued upon exercise of options or warrants, or the vesting of restricted stock units, or in connection with other potential acquisitions or business combinations, or perceptions that those sales and/or conversions or exchanges could occur, could adversely affect the prevailing market price of our ordinary shares and our ability to raise capital in the future.

The adjustment to the conversion rate and the payment of the Fundamental Change Dividend Make-whole Amount upon the occurrence of certain Fundamental Changes may not adequately compensate you for the lost option value and lost dividends as a result of early conversion upon a Fundamental Change.

If a Fundamental Change (as defined in “Description of Mandatory Convertible Preferred Shares—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-whole Amount”) occurs on or prior to June 15, 2023, the Fundamental Change Conversion Rate will apply to any Mandatory Convertible Preferred Shares converted during the

S-20

Table of Contents

Fundamental Change Conversion Period (as defined in “Description of Mandatory Convertible Preferred Shares—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-whole Amount”). The Fundamental Change Conversion Rate will be determined as described in “Description of Mandatory Convertible Preferred Shares—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-whole Amount.” In addition, with respect to those Mandatory Convertible Preferred Shares converted, you will also receive, among other consideration, a Fundamental Change Dividend Make-whole Amount in cash (subject to our right to deliver ordinary shares in lieu of all or part of such amount in cash), subject to the limitations described in “Description of Mandatory Convertible Preferred Shares—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-whole Amount.” If these limitations to the delivery in shares in payment of the Fundamental Change Dividend Amount are reached, we will pay the shortfall in cash to the extent we are permitted to do so under applicable Jersey law. To the extent we are not permitted to pay in cash or deliver shares in respect of the Fundamental Change Dividend Make-whole Amount, in whole in part, due to limitations of applicable Jersey law, we will make an adjustment to the conversion rate subject to certain limitations; provided that, we will not have an obligation to pay any shortfall in cash if these limitations to the adjustment of the conversion rate are reached, nor shall we have any obligation to deliver ordinary shares in respect of such shortfall if these limitations to the adjustment of the conversion rate are reached.

Although this adjustment to the conversion rate and the payment of the Fundamental Change Dividend Make-whole Amount are generally designed to compensate you for the lost option value of the Mandatory Convertible Preferred Shares and lost dividends that you will suffer as a result of converting your Mandatory Convertible Preferred Shares upon a Fundamental Change, the Fundamental Change Conversion Rate and Fundamental Change Dividend Make-whole Amount are only an approximation of such lost option value and lost dividends and may not adequately compensate you for your actual loss. In addition, if the price of our ordinary shares is less than $             per share or more than $             per share, the feature of the Fundamental Change Conversion Rate will not compensate you for any loss suffered in connection with a Fundamental Change.

Furthermore, our obligation to adjust the conversion rate in connection with a Fundamental Change and pay the Fundamental Change Dividend Make-whole Amount (whether paid or delivered, as the case may be, in cash or ordinary shares) could be considered a penalty under applicable law, in which case the enforceability thereof would be subject to general principles of reasonableness and equitable remedies and therefore may not be enforceable in whole or in part.

The Fixed Conversion Rates of the Mandatory Convertible Preferred Shares may not be adjusted for all dilutive events that may adversely affect the market price of the Mandatory Convertible Preferred Shares or the ordinary shares issuable upon conversion of the Mandatory Convertible Preferred Shares.

The Fixed Conversion Rates of the Mandatory Convertible Preferred Shares are subject to adjustment only for the issuance of certain share dividends on our ordinary shares, subdivisions or combinations of our ordinary shares, the issuance of certain rights, options or warrants to holders of our ordinary shares, distributions of share capital, indebtedness, or assets to holders of our ordinary shares, cash dividends on our ordinary shares, and certain issuer tender or exchange offers as described under “Description of Mandatory Convertible Preferred Shares—Anti-dilution Adjustments.” However, other events, such as employee stock option grants, offerings of our ordinary shares or securities convertible into ordinary shares for cash or in connection with acquisitions, or third-party tender or exchange offers, which may adversely affect the market price of our ordinary shares, may not result in any adjustment, even though these other events may adversely affect the market price of our ordinary shares and, therefore, the market price of the Mandatory Convertible Preferred Shares. In

S-21

Table of Contents

addition, the terms of our Mandatory Convertible Preferred Shares do not restrict our ability to offer ordinary shares or securities convertible into ordinary shares in the future or to engage in other transactions that could dilute our ordinary shares. We have no obligation to consider the specific interests of the holders of our Mandatory Convertible Preferred Shares in engaging in any such offering or transaction.

Regulatory actions may adversely affect the trading price and liquidity of the Mandatory Convertible Preferred Shares.

Investors in, and potential purchasers of, the Mandatory Convertible Preferred Shares who employ, or seek to employ, a convertible arbitrage strategy with respect to the Mandatory Convertible Preferred Shares may be adversely impacted by regulatory developments that may limit or restrict such a strategy. The SEC and other regulatory and self-regulatory authorities have implemented various rules and may adopt additional rules in the future that restrict and otherwise regulate short selling and over-the-counter swaps and security-based swaps, which restrictions and regulations may adversely affect the ability of investors in, or potential purchasers of, the Mandatory Convertible Preferred Shares to conduct a convertible arbitrage strategy with respect to the Mandatory Convertible Preferred Shares. This could, in turn, adversely affect the trading price and liquidity of the Mandatory Convertible Preferred Shares.

The concurrent offering of our ordinary shares, and the possibility of the sale of our ordinary shares in the future, could reduce the market price of our ordinary shares and, in turn, the Mandatory Convertible Preferred Shares.

Concurrently with this offering, we are offering $1.0 billion of our ordinary shares (or $1.15 billion if the underwriters for the Concurrent Ordinary Shares Offering exercise in full their option to purchase additional ordinary shares). This offering is not conditioned on the closing of the concurrent offering of our ordinary shares, and the concurrent offering of our ordinary shares is not conditioned on the closing of this offering. We are not restricted, other than as described in “Underwriting,” from issuing additional ordinary shares, including securities that are convertible into or exchangeable for, or that represent the right to receive, ordinary shares, including any ordinary shares that may be issued upon the conversion of the Mandatory Convertible Preferred Shares. In the future, we may sell additional ordinary shares to raise capital or acquire interests in other companies by using a combination of cash and our ordinary shares or just our ordinary shares. Any of these events may dilute your ownership interest in our company and have an adverse impact on the price of our ordinary shares and, in turn, the Mandatory Convertible Preferred Shares. Furthermore, sales of a substantial amount of our ordinary shares in the public market, or the perception that these sales may occur, could reduce the market price of our ordinary shares and, in turn, the Mandatory Convertible Preferred Shares. This could also impair our ability to raise additional capital through the sale of our securities.

You will have no rights with respect to our ordinary shares until the Mandatory Convertible Preferred Shares are converted, but you may be adversely affected by certain changes made with respect to our ordinary shares.

You will have no rights with respect to our ordinary shares, including voting rights, rights to respond to ordinary share tender offers, if any, and rights to receive dividends or other distributions on ordinary shares, if any (other than through a conversion rate adjustment), prior to the conversion date with respect to a conversion of the Mandatory Convertible Preferred Shares, but your investment in the Mandatory Convertible Preferred Shares may be negatively affected by these events. Upon conversion, you will be entitled to exercise the rights of a holder of ordinary shares only as to matters for which the record date occurs on or after the conversion date. For example, in the event that an amendment is proposed to our memorandum or articles of association requiring shareholder approval

S-22

Table of Contents

and the record date for determining the shareholders of record entitled to vote on the amendment occurs prior to the conversion date, you will not be entitled to vote on the amendment (subject to certain limited exceptions, unless it would materially and adversely affect the special rights, preferences, privileges and voting powers of the Mandatory Convertible Preferred Shares), although you will nevertheless be subject to any changes in the powers, preferences or special rights of our ordinary shares, even if your Mandatory Convertible Preferred Shares have been converted into ordinary shares prior to the effective date of such change. See “Description of Share Capital” in the accompanying prospectus for further discussion of our ordinary shares.

You will have no voting rights with respect to the Mandatory Convertible Preferred Shares except under limited circumstances.

You will have no voting rights with respect to the Mandatory Convertible Preferred Shares, except with respect to certain amendments to the terms of the Mandatory Convertible Preferred Shares, in the case of certain dividend arrearages, in certain other limited circumstances and except as specifically required by applicable Jersey law or by our memorandum and articles of association. You will have no right to vote for any members of our board of directors except in the case of certain dividend arrearages.

If dividends on any Mandatory Convertible Preferred Shares have not been declared and paid for the equivalent of six or more dividend periods (including, for the avoidance of doubt, the dividend period beginning on, and including, the initial issue date of the Mandatory Convertible Preferred Shares and ending on, but excluding, September 15, 2020), whether or not for consecutive dividend periods, the holders of such Mandatory Convertible Preferred Shares, voting together as a single class with holders of all other series of preferred shares ranking equally with the Mandatory Convertible Preferred Shares and having similar voting rights, will be entitled at our next special or annual meeting of shareholders to vote for the election of a total of two additional members of our board of directors, subject to certain limitations described in “Description of Mandatory Convertible Preferred Shares—Voting Rights.”

The Mandatory Convertible Preferred Shares will rank junior to all of our and our subsidiaries’ consolidated liabilities.

In the event of a bankruptcy, liquidation, dissolution or winding up, our assets will be available to pay obligations on the Mandatory Convertible Preferred Shares only after all of our consolidated liabilities have been paid. In addition, the Mandatory Convertible Preferred Shares will rank structurally junior to all existing and future liabilities of our subsidiaries. Your rights to participate in the assets of our subsidiaries upon any bankruptcy, liquidation, dissolution or winding up of any subsidiary will rank junior to the prior claims of that subsidiary’s creditors. In the event of a bankruptcy, liquidation, dissolution or winding up, there may not be sufficient assets remaining, after paying our and our subsidiaries’ liabilities, to pay amounts due on any or all of the Mandatory Convertible Preferred Shares then outstanding. As of March 31, 2020, we had total outstanding indebtedness of approximately $6,224 million, and no outstanding preferred shares. In addition, we have the ability to, and may, incur additional indebtedness in the future.

Our memorandum and articles of association authorize our board of directors to issue one or more additional series of preferred shares and set the terms of the preferred shares without seeking any further approval from our shareholders. Any preferred shares that are issued will rank ahead of our ordinary shares in terms of dividends and liquidation rights. If we issue additional preferred shares, it may adversely affect the market price of our ordinary shares. Our board of directors also has the power, without shareholder approval, subject to applicable Jersey law, to set the terms of any such series of preferred shares that may be issued, including voting rights, dividend rights and preferences

over our ordinary shares with respect to dividends or upon our dissolution, winding-up and liquidation and other terms. If we issue additional preferred shares in the future that have a preference over our ordinary shares with respect to the payment of dividends or upon our liquidation, dissolution, or winding up, or if we issue additional preferred shares with voting rights that dilute the voting power of our ordinary shares, the rights of holders of the Mandatory Convertible Preferred Shares and our ordinary shares or the market price of the Mandatory Convertible Preferred Shares and our ordinary shares could be adversely affected. See “Description of Share Capital—Preferred Shares” in the accompanying prospectus.

Our ability to declare and pay dividends on our share capital, including the Mandatory Convertible Preferred Shares may be limited.

Our declaration and payment of dividends on our share capital, including the Mandatory Convertible Preferred Shares in the future will be determined by our board of directors (or an authorized committee thereof) in its sole discretion and will depend on our financial condition, earnings, growth prospects, other uses of cash, funding requirements, applicable Jersey law and other factors our board of directors deems relevant. Our ability to pay dividends on our share capital may also be limited by the terms of our then-existing contracts.

In addition, under applicable Jersey law, our board of directors (or an authorized committee thereof) may only declare and pay dividends on our share capital out of funds legally available therefor under the Companies (Jersey) Law 1991, as amended. Further, even if we are permitted under Jersey law to declare and pay cash dividends on our share capital, including the Mandatory Convertible Preferred Shares, we may not have sufficient cash to declare and pay dividends in cash on our share capital, including the Mandatory Convertible Preferred Shares.

If upon mandatory conversion we have not declared all or any portion of the accumulated and unpaid dividends payable on the Mandatory Convertible Preferred Shares, the applicable conversion rate will be adjusted so that holders receive an additional number of ordinary shares having a market value generally equal to the amount of such accumulated and unpaid dividends, subject to the limitations described under “Description of the Mandatory Convertible Preferred Shares—Mandatory Conversion.” As a result of such limitations, the market value of such additional number of ordinary shares may be less than the amount of such accumulated and unpaid dividends. To the extent that the amount of such accumulated and unpaid dividends exceeds the product of such number of additional shares and 97% of the Average Price (as defined herein), we will, if we are able to do so under applicable Jersey law, declare and pay such excess amount in cash pro rata to the holders of the Mandatory Convertible Preferred Shares. However, to the extent we are not permitted to do so under applicable Jersey law, you will not receive such dividends or any other consideration in respect thereof.

If upon an early conversion at the option of a holder (other than during a Fundamental Change), we have not declared and paid all or any portion of the accumulated dividends payable on the Mandatory Convertible Preferred Shares for all full dividend periods ending on or before the dividend payment date prior to the related Early Conversion Date, the applicable conversion rate will be adjusted so that converting holders receive an additional number of ordinary shares having a market value generally equal to the amount of such accumulated and unpaid dividends, subject to the limitations described under “Description of Mandatory Convertible Preferred Shares—Early Conversion at the Option of the Holder.” As a result of such limitations, the market value of such additional number of ordinary shares may be less than the amount of such accumulated and unpaid dividends. To the extent that the amount of such accumulated and unpaid dividends exceeds the product of such number of additional shares and the Early Conversion Average Price, we will not have any obligation to pay the shortfall in cash or to deliver ordinary shares in respect of such shortfall.

Table of Contents

If upon an early conversion during the Fundamental Change Conversion Period we have not declared all or any portion of the accumulated and unpaid dividends payable on the Mandatory Convertible Preferred Shares for specified periods, we will pay the amount of such accumulated and unpaid dividends in cash, ordinary shares or any combination thereof, in our sole discretion, subject to the limitations described under “Description of Mandatory Convertible Preferred Shares—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-whole Amount.” If these limitations to the delivery in shares in payment of accumulated and unpaid dividends are reached, we will pay the shortfall in cash if we are permitted to do so under applicable Jersey law. However, to the extent we are not permitted to do so under applicable Jersey law, you will not receive such dividends or any other consideration in respect thereof.

You may be subject to tax upon an adjustment to the conversion rate of the Mandatory Convertible Preferred Shares or upon a distribution paid in ordinary shares even though you do not receive a corresponding cash distribution.

The conversion rate of the Mandatory Convertible Preferred Shares is subject to adjustment in certain circumstances. See “Description of Mandatory Convertible Preferred Shares—Anti-dilution Adjustments.” If your proportionate interest in our assets or earnings and profits is increased as a result of an adjustment (or failure to make an adjustment), you may be deemed to have received, for U.S. federal income tax purposes and Irish income tax purposes, a taxable dividend without the receipt of any cash or property. In addition, we may make distributions to holders of the Mandatory Convertible Preferred Shares that are paid (in whole or in part) in ordinary shares, and, although there is some uncertainty for U.S. federal income tax purposes, we believe that any such distribution will be taxable to the same extent as an equivalent cash distribution would be taxable. In these circumstances and possibly others, a holder of Mandatory Convertible Preferred Shares generally will be subject to tax even though it has received no cash with which to pay that tax, thus giving rise to an out-of-pocket expense.

See “Tax Considerations—U.S. Federal Income Tax Considerations” for a further discussion of the material U.S. federal income tax implications for U.S. Holders (as defined therein) of an investment in the Mandatory Convertible Preferred Shares and any ordinary shares received in exchange therefor.

See “Tax Considerations—Irish Tax Considerations” for a further discussion of the Irish tax implications for Non-Irish Holders (as defined therein) of an investment in the Mandatory Convertible Preferred Shares and any ordinary shares received in exchange therefor.

Certain rights of the holders of the Mandatory Convertible Preferred Shares could delay or prevent an otherwise beneficial takeover or takeover attempt of us and, therefore, the ability of holders of Mandatory Convertible Preferred Shares to exercise their rights associated with a potential Fundamental Change.

Certain rights of the holders of the Mandatory Convertible Preferred Shares could make it more difficult or more expensive for a third party to acquire us. For example, if a Fundamental Change were to occur on or prior to June 15, 2023, holders of the Mandatory Convertible Preferred Shares may have the right to convert their Mandatory Convertible Preferred Shares, in whole or in part, at an increased conversion rate and will also be entitled to receive a Fundamental Change Dividend Make-whole Amount equal to the present value of all remaining dividend payments on their Mandatory Convertible Preferred Shares. See “Description of Mandatory Convertible Preferred Shares—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-whole Amount.” These features of the Mandatory Convertible Preferred Shares could increase the cost of acquiring us or otherwise discourage a third party from acquiring us or removing incumbent management.

S-25

Table of Contents

In addition, provisions of Jersey law and our memorandum and articles of association could make it more difficult for a third party to acquire control of us or have the effect of discouraging a third party from attempting to acquire control of us. See “—Risks Related to Our Ordinary Shares—Provisions of our Articles of Association could delay or prevent a takeover of us by a third party.”

An active trading market for the Mandatory Convertible Preferred Shares does not exist and may not develop.

The Mandatory Convertible Preferred Shares are a new issue of securities with no established trading market. The liquidity of the trading market in the Mandatory Convertible Preferred Shares, and the market price quoted for the Mandatory Convertible Preferred Shares, may be adversely affected by changes in the overall market for this type of security and by changes in our financial performance or prospects or in the prospects for companies in our industry generally. We intend to apply to list the Mandatory Convertible Preferred Shares on NYSE under the symbol “APTV PR A.” Even if the Mandatory Convertible Preferred Shares are approved for listing on NYSE, such listing does not guarantee that a trading market for the Mandatory Convertible Preferred Shares will develop or, if a trading market for the Mandatory Convertible Preferred Shares does develop, the depth or liquidity of that market. If an active trading market does not develop or is not maintained, the market price and liquidity of the Mandatory Convertible Preferred Shares may be adversely affected. In that case you may not be able to sell your Mandatory Convertible Preferred Shares at a particular time or you may not be able to sell your Mandatory Convertible Preferred Shares at a favorable price. In addition, as the Mandatory Convertible Preferred Shares are converted, the liquidity of the Mandatory Convertible Preferred Shares that remains outstanding may decrease.

This offering is not contingent on the consummation of the Concurrent Ordinary Shares Offering.

The consummation of this offering and the consummation of the Concurrent Ordinary Shares Offering are not contingent upon one another. We cannot assure you that the Concurrent Ordinary Shares Offering will be consummated on the anticipated time frame, or at all. Accordingly, if you decide to purchase Mandatory Convertible Preferred Shares in this offering, you should be willing to do so whether or not we complete the Concurrent Ordinary Shares Offering.

Risks Related to Our Ordinary Shares

The market price and trading volume of our ordinary shares may be volatile, which could result in rapid and substantial losses for our shareholders.

The market price of our ordinary shares may be highly volatile and could be subject to wide fluctuations. In addition, the trading volume of our ordinary shares may fluctuate and cause significant price variations to occur. Some of the factors that could negatively affect the price of our ordinary shares, or result in fluctuations in the price or trading volume of our ordinary shares, include:

S-26

Table of Contents

In the event of a drop in the market price of our ordinary shares, you could lose a substantial part or all of your investment in our ordinary shares. Consequently, you may not be able to sell our ordinary shares at prices equal to or greater than the price paid by you in the offering.

Reports published by securities or industry analysts, including projections in those reports that exceed our actual results, could adversely affect our share price and trading volume.

Securities research analysts publish their own annual and/or quarterly projections regarding our operating results. These projections may vary widely from one another and may not accurately predict the results we actually achieve. Our share price may decline if we fail to meet securities research analysts’ projections. Similarly, if one or more of the analysts who covers us downgrades our shares or publishes inaccurate or unfavorable research about our business, our share price could decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, our share price or trading volume could decline. Additionally, while we are covered by securities research analysts, if securities or industry analysts cease coverage of us at any time, the trading price of our shares and the trading volume could decline.

The availability of ordinary shares for sale in the future could reduce the market price of our ordinary shares.

In the future, we may issue additional securities to raise capital. We may also acquire interests in other companies by using a combination of cash and our ordinary shares or just our ordinary shares. We may also issue securities convertible into our ordinary shares. Any of these events may dilute your ownership interest in our Company and have an adverse impact on the price of our ordinary shares. In addition, sales of a substantial amount of our ordinary shares in the public market, or the perception that these sales may occur, could reduce the market price of our ordinary shares. This could also impair our ability to raise additional capital through the sale of our securities.

Provisions of our Articles of Association could delay or prevent a takeover of us by a third party.

Our Articles of Association could delay, defer or prevent a third party from acquiring us, despite any possible benefit to our shareholders, or otherwise adversely affect the price of our ordinary shares. For example, our Articles of Association:

S-27

Table of Contents

These provisions may discourage potential takeover attempts, discourage bids for our ordinary shares at a premium over the market price or adversely affect the market price of, and the voting and other rights of the holders of, our ordinary shares. These provisions could also discourage proxy contests and make it more difficult for you and other shareholders to elect directors other than the candidates nominated by our board of directors.

The rights of shareholders of Jersey corporations differ in some respects from those of shareholders of U.S. corporations.

We are incorporated under the laws of Jersey. The rights of holders of ordinary shares are governed by Jersey law, including the Companies (Jersey) Law 1991, as amended, and by our Articles of Association. These rights differ in some respects from the rights of shareholders in corporations incorporated in the United States, and holders of our ordinary shares may have more difficulty protecting their interests than would shareholders of a corporation incorporated in a jurisdiction within the United States. See “Description of Share Capital” in the accompanying prospectus.

The Mandatory Convertible Preferred Shares may adversely affect the market price of our ordinary shares.

The market price of our ordinary shares is likely to be influenced by the Mandatory Convertible Preferred Shares. For example, the market price of our ordinary shares could become more volatile and could be depressed by:

Our ordinary shares will rank junior to our Mandatory Convertible Preferred Shares with respect to dividends and amounts payable in the event of our liquidation, dissolution or winding-up of our affairs.

Our ordinary shares will rank junior to our Mandatory Convertible Preferred Shares with respect to the payment of dividends and amounts payable in the event of our liquidation, dissolution or winding-up of our affairs. This means that, unless accumulated dividends have been paid on all our Mandatory Convertible Preferred Shares through the most recently completed dividend period, no dividends may be declared or paid on our ordinary shares and we will not be permitted to repurchase any of our ordinary shares, subject to limited exceptions. Likewise, in the event of our voluntary or involuntary liquidation, dissolution or winding-up of our affairs, no distribution of our assets may be made to holders of our ordinary shares until we have paid to holders of our Mandatory Convertible Preferred Shares a liquidation preference equal to $100 per share plus accumulated and unpaid dividends.

Holders of our Mandatory Convertible Preferred Shares will have the right to elect two directors in the case of certain dividend arrearages.

If dividends on any our Mandatory Convertible Preferred Shares have not been declared and paid for the equivalent of six or more quarterly dividend periods, whether or not for consecutive dividend

periods, the holders of our Mandatory Convertible Preferred Shares, voting together as a single class with holders of any and all other series of our share capital on a parity with our Mandatory Convertible Preferred Shares (as to the payment of dividends and amounts payable on a liquidation, dissolution or winding up of our affairs) upon which like voting rights have been conferred and are exercisable will be entitled to vote for the election of a total of two additional members of our board of directors, subject to certain terms and limitations. This right to elect directors will dilute the representation of the holders of our ordinary shares on our board of directors and may adversely affect the market price of our ordinary shares.

We may use the net proceeds of this offering in ways with which you may not agree and in ways that may not generate profitable or advantageous returns.

We intend to use the net proceeds of this offering for general corporate purposes, which may include, without limitation and in our sole discretion, funding potential future investments (including acquisitions), capital expenditures, working capital, repayment of outstanding indebtedness, and satisfaction of other obligations. The precise amounts and timing of these uses of proceeds will depend on our funding requirements and those of our subsidiaries. See “Use of Proceeds.” You may not agree with the ways we decide to use the proceeds of this offering, and our use of the proceeds may not generate profitable or advantageous returns.

USE OF PROCEEDS

We estimate that the net proceeds from this offering will be approximately $969 million, after deducting underwriting discounts and commissions and our estimated offering expenses. If the underwriters’ over-allotment option is exercised in full, we estimate that the net proceeds from this offering will be approximately $1,115 million, after deducting underwriting discounts and commissions and our estimated offering expenses. We intend to use the estimated net proceeds of this offering for general corporate purposes, which may include, without limitation and in our sole discretion, funding potential future investments (including acquisitions), capital expenditures, working capital, repayment of outstanding indebtedness, and satisfaction of other obligations. The precise amounts and timing of these uses of proceeds will depend on our funding requirements and those of our subsidiaries. We may invest the net proceeds of this offering in short-term bank deposits or interest-bearing, investment-grade securities or use such proceeds to repay our revolving credit borrowings until they are used for their stated purpose. Certain of the underwriters and/or their respective affiliates that are lenders under our credit facility may receive a portion of the proceeds of this offering to the extent such proceeds are used to repay our revolving credit borrowings. See “Underwriting—Other Relationships.”

DIVIDEND POLICY

We have historically paid quarterly cash dividends on our ordinary shares. During the first quarter of 2020, following the payment of our first quarter dividend, we suspended our annual cash dividend of $0.88 per ordinary share, primarily to provide additional liquidity and financial flexibility to mitigate the impacts on our business resulting from the uncertainty caused by the global spread of the COVID-19 pandemic. Any future determination as to the declaration and payment of dividends will be at the discretion of our board of directors, subject to compliance with contractual covenants, and will depend on our results of operations, financial condition, capital requirements and other factors that our board of directors may deem relevant.

CONCURRENT ORDINARY SHARES OFFERING

Concurrently with this offering of our Mandatory Convertible Preferred Shares and pursuant to a separate prospectus supplement, we are offering $1.0 billion of our ordinary shares (or $1.15 billion if the underwriters for the Concurrent Ordinary Shares Offering exercise in full their option to purchase additional ordinary shares) in an underwritten public offering. However, amounts sold in each offering may increase or decrease based on market conditions relating to a particular security. This offering is not contingent upon the closing of our Concurrent Ordinary Shares Offering and our Concurrent Ordinary Shares Offering is not contingent upon the closing of this offering. We cannot assure you that the Concurrent Ordinary Shares Offering will be completed.

Assuming no exercise of the underwriters’ option to purchase additional ordinary shares, we estimate that the net proceeds of the Concurrent Ordinary Shares Offering, after deducting underwriting discounts and commissions and our estimated offering expenses, will be approximately $969 million.

DESCRIPTION OF MANDATORY CONVERTIBLE PREFERRED SHARES

The following description is a summary of certain provisions of our     % Series A Mandatory Convertible Preferred Shares, par value $0.01 per share (the “Mandatory Convertible Preferred Shares”). The following summary supplements and, to the extent that it is inconsistent therewith, replaces the description of our preferred shares in the accompanying prospectus.

A copy of the statement of rights setting forth the terms of the Mandatory Convertible Preferred Shares, which we refer to as the “Statement of Rights,” as well as our memorandum and articles of association, which we refer to as our “Articles,” is available upon request from us at the address set forth in the section of this prospectus supplement entitled “Where You Can Find More Information.” This description of the terms of the Mandatory Convertible Preferred Shares is not complete and is subject to, and qualified in its entirety by reference to, the provisions of our Articles and the Statement of Rights.

For purposes of this description, references to:

General

Under our Articles, our board of directors is authorized to provide, without further shareholder action, for the issuance of up to 50,000,000 preferred shares, par value of $0.01 per share, and the designation of each series of preferred shares and, with respect to each such series, to fix the number of shares constituting such series and fix the voting power, full or limited or no voting power, the powers, preferences and relative, participating, option or other special rights, if any, and any qualifications, limitations or restrictions thereof, of the shares of each series. As of the date of this prospectus supplement, no preferred shares are outstanding.

At the closing of this offering, we will issue 10,000,000 Mandatory Convertible Preferred Shares. In addition, we have granted the underwriters an option to purchase up to 1,500,000 additional Mandatory Convertible Preferred Shares, solely to cover over-allotments, as described under “Underwriting.”

When issued, the Mandatory Convertible Preferred Shares and our ordinary shares issued upon the conversion of the Mandatory Convertible Preferred Shares will be fully paid and nonassessable.

Ranking

The Mandatory Convertible Preferred Shares, with respect to dividend rights and/or distribution rights upon our liquidation, winding-up or dissolution, as applicable, will rank:

In addition, with respect to dividend rights and distribution rights upon our liquidation, winding-up or dissolution, the Mandatory Convertible Preferred Shares will be structurally subordinated to existing and future indebtedness and other obligations of each of our subsidiaries. See “Risk Factors—Risks Related to the Mandatory Convertible Preferred Shares—The Mandatory Convertible Preferred Shares will rank junior to all of our consolidated liabilities.”

As of March 31, 2020, we had total outstanding indebtedness of approximately $6.2 billion, and no outstanding preferred shares. We have the ability to, and may incur, additional indebtedness in the future.

Listing

We intend to apply to list the Mandatory Convertible Preferred Shares on the NYSE under the symbol “APTV PR A” and, if approved, we expect trading to commence within 30 days of the Initial Issue Date. In addition, upon listing, we have agreed to use our commercially reasonable efforts to keep the Mandatory Convertible Preferred Shares listed on NYSE so long as the ordinary shares are listed on NYSE. However, there can be no assurance that the Mandatory Convertible Preferred Shares will be listed, and if listed, that it will continue to be listed. Listing the Mandatory Convertible Preferred Shares on NYSE does not guarantee that a trading market will develop or, if a trading market does develop, the depth of that market or the ability of holders to sell their Mandatory Convertible Preferred Shares easily.

Dividends

Subject to the rights of holders of any class or series of our share capital ranking senior to the Mandatory Convertible Preferred Shares as to dividend rights, holders of the Mandatory Convertible

S-36

Table of Contents

Preferred Shares will be entitled to receive, when, as and if declared by our board of directors, or an authorized committee thereof, out of funds legally available therefor under The Companies (Jersey) Law 1991, as amended) (collectively, the “funds available to pay dividends”), in the case of dividends paid in cash, and ordinary shares legally permitted to be issued, in the case of dividends paid in ordinary shares, cumulative dividends at the rate per annum of     % of the Liquidation Preference of $100.00 per Mandatory Convertible Preferred Share (equivalent to $            per annum per share), payable in cash, by delivery of ordinary shares or through any combination of cash and ordinary shares, as determined by us in our sole discretion (subject to the limitations described below). See “—Method of Payment of Dividends.”

If declared, dividends on the Mandatory Convertible Preferred Shares will be payable quarterly on March 15, June 15, September 15 and December 15 of each year to, and including, June 15, 2023 commencing on September 15, 2020 (each, a “Dividend Payment Date”), at such annual rate, and dividends shall accumulate from the most recent date as to which dividends shall have been paid or, if no dividends have been paid, from the Initial Issue Date of the Mandatory Convertible Preferred Shares, whether or not in any dividend period or periods there have been funds available to pay dividends.

If declared, dividends will be payable on the relevant Dividend Payment Date to holders of record of the Mandatory Convertible Preferred Shares as they appear on our share register at the close of business on the March 1, June 1, September 1 and December 1, as the case may be, immediately preceding the relevant Dividend Payment Date (each, a “Regular Record Date”), whether or not such holders early convert their shares, or such shares are automatically converted, after a Regular Record Date and on or prior to the immediately succeeding Dividend Payment Date. These Regular Record Dates will apply regardless of whether a particular Regular Record Date is a Business Day. If a Dividend Payment Date is not a Business Day, payment will be made on the next succeeding Business Day, without any interest or other payment in lieu of interest accruing with respect to this delay.

A full dividend period is the period from, and including, a Dividend Payment Date to, but excluding, the next Dividend Payment Date, except that the initial dividend period will commence on, and include, the Initial Issue Date of the Mandatory Convertible Preferred Shares and will end on, and exclude, the September 15, 2020 Dividend Payment Date. The amount of dividends payable on each Mandatory Convertible Preferred Share for each full dividend period (subsequent to the initial dividend period) will be computed by dividing the annual dividend rate by four. Dividends payable on the Mandatory Convertible Preferred Shares for the initial dividend period and any other partial dividend period will be computed based upon the actual number of days elapsed during the period over a 360-day year (consisting of twelve 30-day months). Accordingly, the dividend on the Mandatory Convertible Preferred Shares for the initial dividend period, assuming the Initial Issue Date is                 , 2020 will be $             per Mandatory Convertible Preferred Share (based on the annual dividend rate of     % and a Liquidation Preference of $100.00 per share) and will be payable, when, as and if declared, on September 15, 2020 to the holders of record thereof on September 1, 2020. The dividend on the Mandatory Convertible Preferred Shares for each subsequent full dividend period, when, as and if declared, will be $             per Mandatory Convertible Preferred Share (based on the annual dividend rate of      % and a Liquidation Preference of $100.00 per share). Accumulated dividends on the Mandatory Convertible Preferred Shares will not bear interest, nor shall additional dividends be payable thereon, if they are paid subsequent to the applicable Dividend Payment Date.

No dividend will be paid unless and until our board of directors, or an authorized committee of our board of directors, declares a dividend payable with respect to the Mandatory Convertible Preferred Shares. No dividend will be declared or paid upon, or any sum of cash or number of ordinary shares set apart for the payment of dividends upon, any outstanding Mandatory Convertible Preferred Shares with respect to any dividend period unless all dividends for all preceding dividend periods have been

S-37

Table of Contents

declared and paid upon, or a sufficient sum of cash or number of ordinary shares has been set apart for the payment of such dividends upon, all outstanding Mandatory Convertible Preferred Shares.

Our ability to declare and pay dividends may be limited by the terms of our and our subsidiaries’ existing and any future indebtedness. In addition, our ability to declare and pay dividends may be limited by applicable Jersey law. See “Risk Factors—Risks Related to the Mandatory Convertible Preferred Shares—Our ability to declare and pay dividends on the Mandatory Convertible Preferred Shares may be limited.”

Method of Payment of Dividends

Subject to the limitations described below, we may pay any declared dividend (or any portion of any declared dividend) on the Mandatory Convertible Preferred Shares (whether or not for a current dividend period or any prior dividend period) determined in our sole discretion:

We will make each payment of a declared dividend on the Mandatory Convertible Preferred Shares in cash, except to the extent we elect to make all or any portion of such payment in ordinary shares. We will give the holders of the Mandatory Convertible Preferred Shares notice of any such election, and the portion of such payment that will be made in cash and the portion that will be made in ordinary shares no later than ten Scheduled Trading Days (as defined under “—Mandatory Conversion—Definitions”) prior to the Dividend Payment Date for such dividend; provided that if we do not provide timely notice of this election, we will be deemed to have elected to pay the relevant dividend in cash.

All cash payments to which a holder of the Mandatory Convertible Preferred Shares is entitled in connection with a declared dividend on the Mandatory Convertible Preferred Shares will be computed to the nearest cent. If we elect to make any such payment of a declared dividend, or any portion thereof, in ordinary shares, such shares shall be valued for such purpose, in the case of any dividend payment or portion thereof, at 97% of the Average VWAP (as defined under “—Mandatory Conversion—Definitions”) per ordinary share over the five consecutive Trading Day (as defined under “—Mandatory Conversion— Definitions”) period ending on, and including, the Trading Day prior to the applicable Dividend Payment Date, or the “Average Price.”

No fractional ordinary shares will be delivered to the holders of the Mandatory Convertible Preferred Shares in payment or partial payment of dividends. We will instead pay a cash adjustment (computed to the nearest cent) to each holder that would otherwise be entitled to a fraction of an ordinary share based on the Average Price with respect to such dividend.

To the extent a shelf registration statement is required in our reasonable judgment in connection with the issuance of or for resales of ordinary shares issued as payment of a dividend on the Mandatory Convertible Preferred Shares, including dividends paid in connection with a conversion, we will, to the extent such a shelf registration statement is not currently filed and effective, use our commercially reasonable efforts to file and maintain the effectiveness of such a shelf registration statement until the earlier of such time as all such ordinary shares have been resold thereunder and such time as all such shares are freely tradable without registration by holders thereof that are not, and have not been within the three months preceding, “affiliates” of ours for purposes of the Securities Act. To the extent applicable, we will also use our commercially reasonable efforts to have the ordinary

S-38

Table of Contents

shares approved for listing on NYSE (or if our ordinary shares are not listed on NYSE, on the principal other U.S. national or regional securities exchange on which our ordinary shares are then listed), and qualified or registered under applicable state securities laws, if required; provided that we will not be required to qualify as a foreign corporation or to take any action that would subject us to general service of process in any such jurisdiction where we are not presently qualified or where we are not presently subject to taxation as a foreign corporation and such qualification or action would subject us to such taxation.

Notwithstanding the foregoing, in no event will the number of ordinary shares delivered in connection with any declared dividend, including any declared dividend payable in connection with a conversion, exceed a number equal to:

To the extent that the amount of the declared dividend exceeds the product of (x) the number of ordinary shares delivered in connection with such declared dividend and (y) 97% of the Average Price, we will, if we are able to do so under applicable Jersey law, notwithstanding any notice by us to the contrary, pay such excess amount in cash (computed to the nearest cent). To the extent that we are not able to pay such excess amount in cash under applicable Jersey law, we will not have any obligation to pay such amount in cash or deliver additional ordinary shares in respect of such amount.

Dividend Stopper

So long as any Mandatory Convertible Preferred Share remains outstanding, no dividend or distribution shall be declared or paid on our ordinary shares or any other class or series of Junior Shares, and no ordinary shares or any other class or series of Junior Shares or Parity Shares shall be, directly or indirectly, purchased, redeemed or otherwise acquired for consideration by us or any of our subsidiaries unless all accumulated and unpaid dividends for all preceding dividend periods have been declared and paid in full in cash, ordinary shares or a combination thereof upon, or a sufficient sum of cash or number of ordinary shares has been set apart for the payment of such dividends upon, all outstanding Mandatory Convertible Preferred Shares.

The foregoing limitation shall not apply to:

S-39

Table of Contents

The phrase “Share Dilution Amount” means the increase in the number of diluted ordinary shares outstanding (determined in accordance with U.S. GAAP, and as measured from the Initial Issue Date) resulting from the grant, vesting or exercise of equity-based compensation to directors, employees and agents and equitably adjusted for any share split, share dividend, reverse share split, reclassification or similar transaction.

When dividends on the Mandatory Convertible Preferred Shares (i) have not been paid in full on any Dividend Payment Date (or, in the case of Parity Shares having dividend payment dates different from such Dividend Payment Dates, on a dividend payment date falling within a regular dividend period related to such Dividend Payment Date), or (ii) have been declared but a sum of cash or number of ordinary shares sufficient for payment thereof has not been set aside for the benefit of the holders thereof on the applicable Regular Record Date, no dividends may be declared or paid on any Parity Shares unless dividends are declared on the Mandatory Convertible Preferred Shares such that the respective amounts of such dividends declared on the Mandatory Convertible Preferred Shares and such Parity Shares shall be allocated pro rata among the holders of the Mandatory Convertible Preferred Shares and the holders of any Parity Shares then outstanding. For purposes of calculating the pro rata allocation of partial dividend payments, we shall allocate those payments so that the respective amounts of those payments for the declared dividend bear the same ratio to each other as all accumulated and unpaid dividends per share on the Mandatory Convertible Preferred Shares and such Parity Shares bear to each other (subject to their having been declared by our board of directors, or an authorized committee thereof, out of funds available to pay dividends); provided that any unpaid dividends on the Mandatory Convertible Preferred Shares will continue to accumulate. For purposes of this calculation, with respect to non-cumulative Parity Shares, we will use the full amount of dividends that would be payable for the most recent dividend period if dividends were declared in full on such non-cumulative Parity Shares.

Subject to the foregoing, and not otherwise, such dividends as may be determined by our board of directors, or an authorized committee thereof, may be declared and paid (payable in cash or other property or securities) on any securities, including our ordinary shares and other Junior Shares, from time to time out of funds available to pay dividends, and holders of the Mandatory Convertible Preferred Shares shall not be entitled to participate in any such dividends.

Redemption

The Mandatory Convertible Preferred Shares will not be redeemable. However, at our option, we may purchase or otherwise acquire (including in an exchange transaction) (by way of converting the

S-40

Table of Contents

relevant shares into redeemable shares and redeeming them) the Mandatory Convertible Preferred Shares from time to time in the open market, by tender or exchange offer or otherwise, without the consent of, or notice to, holders.

In the event of our voluntary or involuntary liquidation, winding-up or dissolution, each holder of the Mandatory Convertible Preferred Shares will be entitled to receive a Liquidation Preference in the amount of $100.00 per Mandatory Convertible Preferred Share, or the “Liquidation Preference,” plus an amount equal to accumulated and unpaid dividends on the shares, whether or not declared, to, but excluding, the date fixed for liquidation, winding-up or dissolution to be paid out of our assets legally available for distribution to our shareholders, after satisfaction of liabilities to our creditors and holders of shares of any class or series of our share capital ranking senior to the Mandatory Convertible Preferred Shares as to distribution rights upon our liquidation, winding-up or dissolution and before any payment or distribution is made to holders of any class or series of our share capital ranking junior to the Mandatory Convertible Preferred Shares as to distribution rights upon our liquidation, winding-up or dissolution (including our ordinary shares). If, upon our voluntary or involuntary liquidation, winding-up or dissolution, the amounts payable with respect to the Liquidation Preference, plus an amount equal to accumulated and unpaid dividends to, but excluding, the date fixed for such liquidation, winding up or dissolution, whether or not declared, on the Mandatory Convertible Preferred Shares and all Parity Shares are not paid in full, the holders of the Mandatory Convertible Preferred Shares and any other such Parity Shares will share equally and ratably in any distribution of our assets in proportion to their respective liquidation preferences and amounts equal to accumulated and unpaid dividends (if any) to which they are entitled. After payment of the full amount of the Liquidation Preference and an amount equal to accumulated and unpaid dividends to which they are entitled, the holders of the Mandatory Convertible Preferred Shares will have no right or claim to any of our remaining assets.

Neither the sale of all or substantially all of our assets or business (other than in connection with our liquidation, winding-up or dissolution), nor our merger or consolidation into or with any other person, will be deemed to be our voluntary or involuntary liquidation, winding-up or dissolution.

The Statement of Rights will not contain any provision requiring funds to be set aside to protect the Liquidation Preference of the Mandatory Convertible Preferred Shares even though it is substantially in excess of the par value thereof.

Voting Rights

The holders of the Mandatory Convertible Preferred Shares will not have voting rights other than those described below, except as specifically required by Jersey law or by our Articles from time to time.

Whenever dividends on any of the Mandatory Convertible Preferred Shares have not been declared and paid for the equivalent of six or more dividend periods (including, for the avoidance of doubt, the dividend period beginning on, and including, the Initial Issue Date and ending on, but excluding, September 15, 2020), whether or not for consecutive dividend periods (a “Nonpayment”), the authorized number of directors on our board of directors will, at the next annual meeting of shareholders or at a special meeting of shareholders as provided below, automatically be increased by two and the holders of such Mandatory Convertible Preferred Shares, voting together as a single class with holders of any and all other series of Voting Preferred Shares (as defined below) then outstanding, will be entitled, at our next annual meeting of shareholders or at a special meeting of shareholders as provided below, to vote for the election of a total of two additional members of our board of directors, or

S-41

Table of Contents

the “Preferred Share Directors”; provided that the election of any such Preferred Share Directors will not cause us to violate our Articles or the corporate governance requirements of NYSE (or any other exchange or automated quotation system on which our securities may be listed or quoted); provided further that our board of directors shall, at no time, include more than two Preferred Share Directors.

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

At any meeting at which the holders of the Mandatory Convertible Preferred Shares are entitled to elect Preferred Share Directors, the holders of a majority of the then outstanding Mandatory Convertible Preferred Shares and all other series of Voting Preferred Shares, present in person or represented by proxy, will constitute a quorum and the vote of the holders of a majority of such Mandatory Convertible Preferred Shares and other Voting Preferred Shares so present or represented by proxy at any such meeting at which there shall be a quorum shall be sufficient to elect the Preferred Share Directors.

As used in this prospectus supplement, “Voting Preferred Shares” means any other class or series of our Parity Shares upon which like voting rights for the election of directors have been conferred and are exercisable. Whether a plurality, majority or other portion in voting power of the Mandatory Convertible Preferred Shares and any other Voting Preferred Shares have been voted in favor of any matter shall be determined by reference to the respective liquidation preference amounts of the Mandatory Convertible Preferred Shares and such other Voting Preferred Shares voted.

If and when all accumulated and unpaid dividends have been paid in full (a “Nonpayment Remedy”), the holders of the Mandatory Convertible Preferred Shares shall immediately and, without any further action by us, be divested of the foregoing voting rights, subject to the revesting of such rights in the event of each subsequent Nonpayment. If such voting rights for the holders of the Mandatory Convertible Preferred Shares and all other holders of Voting Preferred Shares have terminated, the term of office of each Preferred Share Director so elected will terminate at such time and the authorized number of directors on our board of directors shall automatically decrease by two.

Any Preferred Share Director may be removed at any time, with or without cause, by the holders of record of a majority in voting power of the outstanding Mandatory Convertible Preferred Shares and any other series of Voting Preferred Shares then outstanding (voting together as a single class) when they have the voting rights described above. In the event that a Nonpayment shall have occurred and there shall not have been a Nonpayment Remedy, any vacancy in the office of a Preferred Share Director (other than prior to the initial election of Preferred Share Directors after a Nonpayment) may be filled by the written consent of the Preferred Share Director remaining in office, except in the event that such vacancy is created as a result of such Preferred Share Director being removed or if no Preferred Share Director remains in office, such vacancy may be filled by a vote of the holders of record of a majority in voting power of the outstanding Mandatory Convertible Preferred Shares and any other series of Voting Preferred Shares then outstanding (voting together as a single class) when they have the voting rights described above; provided that the election of any such Preferred Share Directors will not cause us to violate our Articles or the corporate governance requirements of NYSE (or any other exchange or automated quotation system on which our securities may be listed or

quoted). The Preferred Share Directors will each be entitled to one vote per director on any matter that comes before our board of directors for a vote.

So long as any Mandatory Convertible Preferred Shares remain outstanding, we will not, without the affirmative vote or consent of the holders of at least two-thirds in voting power of the outstanding Mandatory Convertible Preferred Shares, voting as a separate class, given in person or by proxy, either in writing or at an annual or special meeting of such shareholders:

provided, however, that in the event that a transaction would trigger voting rights under both the second and third bullet point above, the third bullet point will govern; provided, further, however, that each of:

will be deemed not to adversely affect the special rights, preferences, privileges or voting powers of the Mandatory Convertible Preferred Shares and shall not require the affirmative vote or consent of holders of the Mandatory Convertible Preferred Shares.

In addition, without the consent of the holders of the Mandatory Convertible Preferred Shares, so long as such action does not materially adversely affect the rights, preferences, privileges or voting powers of the Mandatory Convertible Preferred Shares and limitations and restrictions thereof, we may amend, alter, supplement or repeal any terms of the Mandatory Convertible Preferred Shares to:

Table of Contents

Without the consent of the holders of the Mandatory Convertible Preferred Shares, we may amend, alter, supplement or repeal any terms of the Mandatory Convertible Preferred Shares to (i) conform the terms of the Mandatory Convertible Preferred Shares to the description thereof in the accompanying prospectus as supplemented and/or amended by this “Description of Mandatory Convertible Preferred Shares” section of the preliminary prospectus supplement for the Mandatory Convertible Preferred Shares, as supplemented by the related pricing term sheet, (ii) file a certificate of correction with respect to the Statement of Rights to the extent permitted by The Companies (Jersey) Law 1991, as amended or (iii) amend the Statement of Rights for the Mandatory Convertible Preferred Shares in connection with a Reorganization Event pursuant to the provisions below under the heading “—Recapitalization, Reclassifications and Changes of Our Ordinary Shares.”

Mandatory Conversion

Each outstanding Mandatory Convertible Preferred Share, unless previously converted, will automatically convert on the Mandatory Conversion Date (as defined below), into a number of ordinary shares equal to the conversion rate described below.

The conversion rate, which is the number of ordinary shares issuable upon conversion of each Mandatory Convertible Preferred Share on the Mandatory Conversion Date (excluding any ordinary shares issued in respect of accumulated and unpaid dividends, as described below), will be as follows:

We refer to the Minimum Conversion Rate and the Maximum Conversion Rate collectively as the “Fixed Conversion Rates.” The “Threshold Appreciation Price” is calculated by dividing $100.00 by the Minimum Conversion Rate, and represents an approximately    % appreciation over the Initial Price. The “Initial Price” is calculated by dividing $100.00 by the Maximum Conversion Rate of                  ordinary shares, and initially is approximately equal to the per share public offering price of our ordinary shares in the concurrent offering of our ordinary shares (or, if such concurrent offering does not price, the closing price of our ordinary shares on June    , 2020). The Fixed Conversion Rates are subject to adjustment as described in “—Anti-dilution Adjustments” below.

If we declare a dividend for the dividend period ending on, but excluding, June 15, 2023, we will pay such dividend to the holders of record as of the immediately preceding Regular Record Date, as described above under “—Dividends.” If on or prior to June 15, 2023 we have not declared all or any portion of the accumulated and unpaid dividends on the Mandatory Convertible Preferred Shares, the conversion rate will be adjusted so that holders receive an additional number of ordinary shares equal to:

S-44

Table of Contents

To the extent that the Mandatory Conversion Additional Conversion Amount exceeds the product of the number of additional shares and 97% of the Average Price, we will, if we are able to do so under applicable Jersey law, pay such excess amount in cash (computed to the nearest cent) pro rata to the holders of the Mandatory Convertible Preferred Shares. To the extent that we are not able to pay such excess amount in cash under applicable Jersey law, we will not have any obligation to pay such amount in cash or deliver additional ordinary shares in respect of such amount.

Hypothetical Conversion Values upon Mandatory Conversion

For illustrative purposes only, the following table shows the number of ordinary shares that a holder of the Mandatory Convertible Preferred Shares would receive upon mandatory conversion of one Mandatory Convertible Preferred Share at various Applicable Market Values for our ordinary shares. The table assumes that there will be no conversion adjustments as described below in “—Anti-dilution Adjustments” and that dividends on the Mandatory Convertible Preferred Shares will be declared and paid in cash (and not in additional ordinary shares). The actual Applicable Market Value of our ordinary shares may differ from those set forth in the table below. Given an Initial Price of approximately $             and a Threshold Appreciation Price of approximately $            , a holder of Mandatory Convertible Preferred Shares would receive on the Mandatory Conversion Date the number of ordinary shares per Mandatory Convertible Preferred Share set forth below:

Accordingly, assuming that the market price of our ordinary shares on the Mandatory Conversion Date is the same as the Applicable Market Value of our ordinary shares, the aggregate market value of our ordinary shares you receive upon mandatory conversion of a Mandatory Convertible Preferred Share (excluding any of our ordinary shares you receive in respect of accumulated and unpaid dividends) will be:

Definitions

“Applicable Market Value” means the Average VWAP per ordinary share over the Settlement Period.

S-45

Table of Contents

“Settlement Period” means the 20 consecutive Trading Day period commencing on, and including, the 21st Scheduled Trading Day immediately preceding June 15, 2023.

“Mandatory Conversion Date” means the second Business Day immediately following the last Trading Day of the Settlement Period. The Mandatory Conversion Date is expected to be June 15, 2023.

A “Trading Day” means a day on which:

provided that if our ordinary shares are not listed or admitted for trading on a Relevant Stock Exchange, “Trading Day” means a “Business Day.”

A “Scheduled Trading Day” is any day that is scheduled to be a Trading Day.

“Market Disruption Event” means:

“Relevant Stock Exchange” means NYSE or, if our ordinary shares are not then listed on NYSE, on the principal other U.S. national or regional securities exchange on which our ordinary shares are then listed or, if our ordinary shares are not then listed on a U.S. national or regional securities exchange, on the principal other market on which our ordinary shares are then listed or admitted for trading.

“VWAP” per ordinary share on any Trading Day means the per share volume-weighted average price as displayed on Bloomberg page “APTV <EQUITY> AQR” (or its equivalent successor if such page is not available) in respect of the period from the scheduled open of trading until the scheduled close of trading of the primary trading session on such Trading Day (or if such volume-weighted average price is not available, the market value per ordinary share on such Trading Day as determined, using a volume-weighted average method, by a nationally recognized independent investment banking firm retained by us for this purpose). The “Average VWAP” per share over a certain period means the arithmetic average of the VWAP per share for each Trading Day in such period.

Early Conversion at the Option of the Holder

Other than during a Fundamental Change Conversion Period (as defined below in “—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-whole Amount”), holders of Mandatory Convertible Preferred Shares have the right to convert their Mandatory Convertible Preferred Shares, in whole or in part (but in no event less than one Mandatory Convertible Preferred Share), at any time prior to June 15, 2023 (an “Early Conversion”), into our ordinary shares at the Minimum Conversion Rate of our ordinary shares per Mandatory Convertible Preferred Share.

S-46

Table of Contents

If, as of the conversion date (as defined below under “—Conversion Procedures—Upon Early Conversion or Upon a Conversion in Connection with a Fundamental Change”) of any Early Conversion, or the “Early Conversion Date,” we have not declared all or any portion of the accumulated and unpaid dividends for all full dividend periods ending on or before the Dividend Payment Date immediately prior to such Early Conversion Date, the conversion rate for such Early Conversion will be adjusted so that holders converting their Mandatory Convertible Preferred Shares at such time receive an additional number of ordinary shares equal to:

To the extent that the Early Conversion Additional Conversion Amount exceeds the product of such number of additional shares and the Early Conversion Average Price, we will not have any obligation to pay the shortfall in cash or deliver ordinary shares in respect of such shortfall.

Except as described above, upon any Early Conversion of any Mandatory Convertible Preferred Shares, we will make no payment or allowance for unpaid dividends on such Mandatory Convertible Preferred Shares, unless such Early Conversion Date occurs after the Regular Record Date for a declared dividend and on or prior to the immediately succeeding Dividend Payment Date, in which case such dividend will be paid on such Dividend Payment Date to the holder of record of the converted Mandatory Convertible Preferred Shares as of such Regular Record Date, as described under “—Dividends.”

Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-whole Amount

General

If a “Fundamental Change” (as defined below) occurs on or prior to June 15, 2023, holders of the Mandatory Convertible Preferred Shares will have the right, or the “Fundamental Change Conversion Right,” during the Fundamental Change Conversion Period (as defined below) to:

subject in the case of clauses (ii) and (iii) to certain limitations with respect to the number of ordinary shares that we will be required to deliver, all as described below. Notwithstanding clauses (ii) and (iii) above, if the Fundamental Change Effective Date (as defined below) or the Fundamental Change Conversion Date (as defined below) falls after the Regular Record Date for a declared dividend and prior to the next Dividend Payment Date, such dividend will be paid on such Dividend Payment Date to the holders as of such Regular Record Date, as described under “—Dividends” and will not be included in the Accumulated Dividend Amount, and the Fundamental Change Dividend Make-whole Amount will not include the present value of the payment of such dividend.

S-47

Table of Contents

To exercise this Fundamental Change Conversion Right, holders must submit their Mandatory Convertible Preferred Shares for conversion at any time during the period, which we call the “Fundamental Change Conversion Period,” beginning on, and including, the Fundamental Change Effective Date and ending at the close of business on the date that is 20 calendar days after the Fundamental Change Effective Date (or, if later, the date that is 20 calendar days after the date of notice of such Fundamental Change), but in no event later than June 15, 2023. Holders of the Mandatory Convertible Preferred Shares that submit the shares for conversion during the Fundamental Change Conversion Period shall be deemed to have exercised their Fundamental Change Conversion Right. Holders of the Mandatory Convertible Preferred Shares who do not submit their shares for conversion during the Fundamental Change Conversion Period will not be entitled to convert their Mandatory Convertible Preferred Shares at the relevant Fundamental Change Conversion Rate or to receive the relevant Fundamental Change Dividend Make-whole Amount or the relevant Accumulated Dividend Amount. The “Fundamental Change Conversion Date” refers to the conversion date (as defined below under “—Conversion Procedures—Upon Early Conversion or Upon a Conversion in Connection with a Fundamental Change”) during the Fundamental Change Conversion Period.

We will notify holders of the Fundamental Change Effective Date no later than the second Business Day immediately following the Fundamental Change Effective Date.

A “Fundamental Change” will be deemed to have occurred, at any time after the Initial Issue Date of the Mandatory Convertible Preferred Shares, if any of the following occurs:

S-48

Table of Contents

However, a transaction or transactions described in clause (i) or clause (ii) above will not constitute a Fundamental Change if at least 90% of the consideration received or to be received by our common shareholders, excluding cash payments for fractional shares or pursuant to statutory appraisal rights, in connection with such transaction or transactions consists of shares of common equity, depositary receipts representing common equity interests or similar certificates, in each case, that are listed or quoted on any of NYSE, the Nasdaq Global Select Market or the Nasdaq Global Market (or any of their respective successors) or will be so listed or quoted when issued or exchanged in connection with such transaction or transactions and as a result of such transaction or transactions such consideration (excluding cash payments for fractional shares or pursuant to statutory appraisal rights) becomes the Exchange Property.

Fundamental Change Conversion Rate

The Fundamental Change Conversion Rate will be determined by reference to the table below and is based on the effective date of the Fundamental Change, or the “Fundamental Change Effective Date,” and the price, or the “Fundamental Change Share Price,” paid (or deemed paid) per ordinary share in such Fundamental Change. If all holders of our ordinary shares receive only cash in exchange for their ordinary shares in the Fundamental Change, the Fundamental Change Share Price shall be the cash amount paid per share. Otherwise, the Fundamental Change Share Price shall be the Average VWAP per ordinary share over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the relevant Fundamental Change Effective Date.

The Fundamental Change Share Prices set forth in the first row of the table (i.e., the column headers) will be adjusted as of any date on which the Fixed Conversion Rates of the Mandatory Convertible Preferred Shares are adjusted. The adjusted Fundamental Change Share Prices will equal (i) the Fundamental Change Share Prices applicable immediately prior to such adjustment, multiplied by (ii) a fraction, the numerator of which is the Minimum Conversion Rate immediately prior to the adjustment giving rise to the Fundamental Change Share Price adjustment and the denominator of which is the Minimum Conversion Rate as so adjusted. Each of the Fundamental Change Conversion Rates in the table will be subject to adjustment in the same manner and at the same time as each Fixed Conversion Rate as set forth in “—Anti-dilution Adjustments.”

The following table sets forth the Fundamental Change Conversion Rate per Mandatory Convertible Preferred Share for each Fundamental Change Share Price and Fundamental Change Effective Date set forth below.

The exact Fundamental Change Share Price and Fundamental Change Effective Date may not be set forth in the table, in which case:

Fundamental Change Dividend Make-whole Amount and Accumulated Dividend Amount

For any Mandatory Convertible Preferred Shares that are converted during the Fundamental Change Conversion Period, in addition to the ordinary shares issued upon conversion at the Fundamental Change Conversion Rate, we will at our option (subject to satisfaction of the requirements described below):

In addition, to the extent that the Accumulated Dividend Amount exists as of the Fundamental Change Effective Date, holders who convert their Mandatory Convertible Preferred Shares within the Fundamental Change Conversion Period will be entitled to receive such Accumulated Dividend Amount upon conversion. As used herein, the term “Accumulated Dividend Amount” means, in connection with a Fundamental Change, the aggregate amount of accumulated and unpaid dividends, if any, for dividend periods prior to the relevant Fundamental Change Effective Date, including for the partial dividend period, if any, from, and including, the Dividend Payment Date immediately preceding such Fundamental Change Effective Date to, but excluding, such Fundamental Change Effective Date. The Accumulated Dividend Amount will be payable at our election (subject to satisfaction of the requirements described below):

We will pay the Fundamental Change Dividend Make-whole Amount and the Accumulated Dividend Amount in cash, except to the extent we elect on or prior to the second Business Day following the Fundamental Change Effective Date to make all or any portion of such payments in ordinary shares.

S-50

Table of Contents

If we elect to deliver ordinary shares in respect of all or any portion of the Fundamental Change Dividend Make-whole Amount or the Accumulated Dividend Amount, to the extent that the Fundamental Change Dividend Make-whole Amount or the Accumulated Dividend Amount (or, if applicable, the dollar amount of any portion thereof paid in ordinary shares) exceeds the product of the number of additional shares we deliver in respect thereof and 97% of the Fundamental Change Share Price, we will, if we are able to do so under applicable Jersey law, pay such excess amount in cash (computed to the nearest cent). To the extent that we are not able to pay such excess amount in cash under applicable Jersey law, we will not have any obligation to pay such amount in cash or deliver additional ordinary shares in respect of such amount.

No fractional ordinary shares will be delivered to converting holders of the Mandatory Convertible Preferred Shares in respect of the Fundamental Change Dividend Make-whole Amount or the Accumulated Dividend Amount. We will instead pay a cash adjustment (computed to the nearest cent) to each converting holder that would otherwise be entitled to a fraction of an ordinary share based on the Average VWAP per ordinary share over the five consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the relevant conversion date.

However, if we are prohibited from paying or delivering, as the case may be, the Fundamental Change Dividend Make-whole Amount (whether in cash or in ordinary shares), in whole or in part, due to limitations of applicable Jersey law, the Fundamental Change Conversion Rate will instead be increased by a number of ordinary shares equal to the cash amount of the aggregate unpaid and undelivered Fundamental Change Dividend Make-whole Amount, divided by the greater of (i) the Floor Price and (ii) 97% of the Fundamental Change Share Price. To the extent that the cash amount of the aggregate unpaid and undelivered Fundamental Change Dividend Make-whole Amount exceeds the product of such number of additional shares and 97% of the Fundamental Change Share Price, we will not have any obligation to pay the shortfall in cash or deliver additional ordinary shares in respect of such amount.

Not later than the second Business Day following the Fundamental Change Effective Date, we will notify holders of:

Our obligation to deliver shares at the Fundamental Change Conversion Rate and pay the Fundamental Change Dividend Make-whole Amount could be considered a penalty, in which case the enforceability thereof would be subject to general principles of reasonableness of economic remedies and therefore may not be enforceable in whole or in part.

Conversion Procedures

Upon Mandatory Conversion

Any outstanding Mandatory Convertible Preferred Shares will automatically convert into ordinary shares on the Mandatory Conversion Date.

If more than one Mandatory Convertible Preferred Share held by the same holder is automatically converted on the Mandatory Conversion Date, the number of ordinary shares issuable upon

S-51

Table of Contents

conversion thereof shall be computed on the basis of the aggregate number of our Mandatory Convertible Preferred Shares so converted.

You will not be required to pay any transfer taxes or duties relating to the issuance or delivery of our ordinary shares upon conversion, but you will be required to pay any tax or duty that may be payable relating to any transfer involved in the issuance or delivery of the ordinary shares in a name other than your own.

So long as the Mandatory Convertible Preferred Shares being converted are in global form, the ordinary shares issuable upon conversion will be delivered to the converting holder through the facilities of DTC, in each case together with delivery by the Company to the converting holder of any cash to which the converting holder is entitled, on the later of (i) the Mandatory Conversion Date and (ii) the Business Day after you have paid in full all applicable taxes and duties, if any.

The person or persons entitled to receive the ordinary shares issuable upon mandatory conversion of the Mandatory Convertible Preferred Shares will be treated as the record holder(s) of such shares as of the close of business on the Mandatory Conversion Date. Except as provided in “—Anti-dilution Adjustments,” prior to the close of business on the Mandatory Conversion Date, the ordinary shares issuable upon conversion of the Mandatory Convertible Preferred Shares will not be deemed to be outstanding for any purpose and you will have no rights with respect to such ordinary shares, including voting rights, rights to respond to tender offers and rights to receive any dividends or other distributions on the ordinary shares, by virtue of holding the Mandatory Convertible Preferred Shares.

Upon Early Conversion or Upon a Conversion in Connection with a Fundamental Change

If a holder elects to convert the Mandatory Convertible Preferred Shares prior to June 15, 2023, in the manner described in “—Early Conversion at the Option of the Holder” or “—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-whole Amount,” you must observe the following conversion procedures:

The “conversion date” will be the date on which you have satisfied the foregoing requirements, to the extent applicable.

If more than one Mandatory Convertible Preferred Share is surrendered for conversion at one time by or for the same holder, the number of ordinary shares issuable upon conversion thereof shall be computed on the basis of the aggregate number of Mandatory Convertible Preferred Shares so surrendered.

You will not be required to pay any taxes or duties relating to the issuance or delivery of our ordinary shares upon conversion, but you will be required to pay any tax or duty that may be payable relating to any transfer involved in the issuance or delivery of the ordinary shares in a name other than your own.

So long as the Mandatory Convertible Preferred Shares being converted are in global form, the ordinary shares will be issued and delivered to the converting holder through the facilities of DTC on

S-52

Table of Contents

the latest of (i) the second Business Day immediately succeeding the conversion date, (ii) the second Business Day immediately succeeding the last day of the Early Conversion Settlement Period and (iii) the Business Day after you have paid in full all applicable taxes and duties, if any.

The person or persons entitled to receive the ordinary shares issuable upon early conversion of the Mandatory Convertible Preferred Shares will be treated as the record holder(s) of such shares as of the close of business on the applicable Early Conversion Date or Fundamental Change Conversion Date. Except as provided in “—Anti-dilution Adjustments,” prior to the close of business on the applicable Early Conversion Date or Fundamental Change Conversion Date, the ordinary shares issuable upon early conversion of the Mandatory Convertible Preferred Shares will not be outstanding for any purpose and you will have no rights with respect to such ordinary shares, including voting rights, rights to respond to tender offers and rights to receive any dividends or other distributions on the ordinary shares, by virtue of holding the Mandatory Convertible Preferred Shares.

Fractional Shares

No fractional ordinary shares will be issued to holders of the Mandatory Convertible Preferred Shares upon conversion. In lieu of any fractional ordinary shares otherwise issuable in respect of the aggregate number of Mandatory Convertible Preferred Shares of any holder that are converted, that holder will be entitled to receive an amount in cash (computed to the nearest cent) equal to the product of: (i) that same fraction; and (ii) the Average VWAP of our ordinary shares over the five consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the relevant conversion date.

Anti-dilution Adjustments

Each Fixed Conversion Rate will be adjusted as described below, except that we will not make any adjustments to the Fixed Conversion Rates if holders of the Mandatory Convertible Preferred Shares participate (other than in the case of a share split or share combination or a tender or exchange offer described in clause (5) below), at the same time and upon the same terms as holders of our ordinary shares and solely as a result of holding the Mandatory Convertible Preferred Shares, in any of the transactions described below without having to convert their Mandatory Convertible Preferred Shares as if they held a number of ordinary shares equal to (i) the Maximum Conversion Rate as of the record date for such transaction, multiplied by (ii) the number of Mandatory Convertible Preferred Shares held by such holder.

Any adjustment made under this clause (1) shall become effective immediately after the close of business on the record date for such dividend or distribution, or immediately after the open of business on the effective date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this clause (1) is declared but not so paid or made, each Fixed Conversion Rate shall be immediately readjusted, effective as of the date our board of directors or a committee thereof determines not to pay such dividend or distribution, to such Fixed Conversion Rate that would then be in effect if such dividend or distribution had not been declared. For the purposes of this clause (1), the number of ordinary shares outstanding immediately prior to the close of business on the relevant record date or immediately prior to the open of business on the relevant effective date, as the case may be, and the number of ordinary shares outstanding immediately after giving effect to such dividend, distribution, share split or share combination shall, in each case, not include shares that we hold in treasury.

“Effective date” as used in this clause (1) means the first date on which the ordinary shares trade on the Relevant Stock Exchange, regular way, reflecting the relevant share split or share combination, as applicable.

“Record date” means, with respect to any dividend, distribution or other transaction or event in which the holders of our ordinary shares (or other applicable security) have the right to receive any cash, securities or other property or in which our ordinary shares (or such other security) are exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of holders of our ordinary shares (or such other security) entitled to receive such cash, securities or other property (whether such date is fixed by our board of directors or a duly authorized committee thereof, statute, contract or otherwise).

Table of Contents

Any increase made under this clause (2) will be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the close of business on the record date for such issuance. To the extent that such rights, options or warrants are not exercised prior to their expiration or ordinary shares are not delivered after the exercise of such rights, options or warrants, each Fixed Conversion Rate shall be decreased to such Fixed Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of ordinary shares actually delivered, if any. If such rights, options or warrants are not so issued, or if no such rights, options or warrants are exercised prior to their expiration, each Fixed Conversion Rate shall be immediately readjusted, effective as of the date our board of directors or a committee thereof determines not to pay such dividend or distribution, or upon such expiration, as the case may be, to such Fixed Conversion Rate that would then be in effect if such record date for such issuance had not occurred.

For the purpose of this clause (2), in determining whether any rights, options or warrants entitle the holders of our ordinary shares to subscribe for or purchase ordinary shares at less than such Average VWAP per share for the ten consecutive trading day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, and in determining the aggregate offering price of such ordinary shares, there shall be taken into account any consideration received by us for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by us in good faith (which determination will be final).

S-55

Table of Contents

then each Fixed Conversion Rate will be increased based on the following formula:

where,

“Ex-date” means the first date on which the ordinary shares trade on the applicable exchange or in the applicable market, regular way, without the right to receive the issuance, dividend or distribution in question, from us or, if applicable, from the seller of our ordinary shares on such exchange or market (in the form of due bills or otherwise) as determined by such exchange or market.

Any increase made under the portion of this clause (3) above will become effective immediately after the close of business on the record date for such distribution. If such distribution is not so paid or made, each Fixed Conversion Rate shall be immediately readjusted, effective as of the date our board of directors or a committee thereof determines not to pay such dividend or distribution, to be such Fixed Conversion Rate that would then be in effect if such distribution had not been declared.

Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP₀” (as defined above), in lieu of the foregoing increase, each holder shall receive, in respect of each Mandatory Convertible Preferred Share, at the same time and upon the same terms as holders of our ordinary shares, the amount and kind of our share capital, evidences of our indebtedness, other assets or property of ours or rights, options or warrants to acquire our share capital or other securities that such holder would have received if such holder owned a number of ordinary shares equal to the Maximum Conversion Rate in effect on the record date for the distribution.

If we issue rights, options or warrants that are only exercisable upon the occurrence of certain triggering events, then:

With respect to an adjustment pursuant to this clause (3) where there has been a payment of a dividend or other distribution on our ordinary shares of shares of share capital of any class or series, or similar equity interest, of or relating to a subsidiary or other business unit, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange, which we refer to as a “spin-off,” each Fixed Conversion Rate will be increased based on the following formula:

S-56

Table of Contents

where,

The increase to each Fixed Conversion Rate under the preceding paragraph will be calculated as of the close of business on the last Trading Day of the valuation period but will be given retroactive effect as of immediately after the open of business on the ex-date of the spin-off. Because we will make the adjustment to each Fixed Conversion Rate with retroactive effect, we will delay the settlement of any conversion of Mandatory Convertible Preferred Shares where any date for determining the number of ordinary shares issuable to a holder occurs during the valuation period until the second Business Day after the last Trading Day of such valuation period. If such dividend or distribution is not so paid, each Fixed Conversion Rate shall be decreased, effective as of the date our board of directors or a committee thereof determines not to make or pay such dividend or distribution, to be such Fixed Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

Any increase made under this clause (4) shall become effective immediately after the close of business on the record date for such dividend or distribution. If such dividend or distribution is not so paid, each Fixed Conversion Rate shall be decreased, effective as of the date our board of directors or a committee thereof determines not to make or pay such dividend or distribution, to be such Fixed Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP₀” (as defined above), in lieu of the foregoing increase, each holder shall receive, in respect of each

Mandatory Convertible Preferred Share, at the same time and upon the same terms as holders of our ordinary shares, the amount of cash that such holder would have received if such holder owned a number of ordinary shares equal to the Maximum Conversion Rate on the record date for such cash dividend or distribution.

where,

The increase to each Fixed Conversion Rate under the preceding paragraph will be calculated at the close of business on the last Trading Day of the averaging period but will be given retroactive effect as of immediately after the close of business on the expiration date. Because we will make the adjustment to each Fixed Conversion Rate with retroactive effect, we will delay the settlement of any conversion of Mandatory Convertible Preferred Shares where any date for determining the number of ordinary shares issuable to a holder occurs during the averaging period until the second Business Day after the last Trading Day of such averaging period. For the avoidance of doubt, no adjustment under this clause (5) will be made if such adjustment would result in a decrease in any Fixed Conversion Rate.

In the event that we or one of our subsidiaries is obligated to purchase ordinary shares pursuant to any such tender offer or exchange offer, but we or such subsidiary is permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then each Fixed Conversion Rate shall again be adjusted to be such Fixed Conversion Rate that would then be in effect if such tender offer or exchange offer had not been made (or had been made only in respect of the purchases that have been made and not rescinded).

S-58

Table of Contents

We may, to the extent permitted by law and the rules of NYSE or any other securities exchange on which our ordinary shares or the Mandatory Convertible Preferred Shares are then listed, increase each Fixed Conversion Rate by any amount for a period of at least 20 Business Days if such increase is irrevocable during such 20 Business Days and we determine that such increase would be in our best interest. In addition, we may make such increases in each Fixed Conversion Rate as we deem advisable in order to avoid or diminish any income tax to holders of our ordinary shares resulting from any dividend or distribution of our ordinary shares (or issuance of rights or warrants to acquire our ordinary shares) or from any event treated as such for income tax purposes or for any other reason. We may only make such a discretionary adjustment if we make the same proportionate adjustment to each Fixed Conversion Rate.

Holders of the Mandatory Convertible Preferred Shares may, in certain circumstances, including a distribution of cash dividends to holders of our ordinary shares, be deemed to have received a distribution subject to U.S. Federal income tax as a dividend as a result of an adjustment or the nonoccurrence of an adjustment to the Fixed Conversion Rates. See “Tax Considerations—U.S. Federal Income Tax Considerations.”

If we have a rights plan in effect upon conversion of the Mandatory Convertible Preferred Shares into ordinary shares, you will receive, in addition to any ordinary shares received in connection with such conversion, the rights under the rights plan. However, if, prior to any conversion, the rights have separated from the ordinary shares in accordance with the provisions of the applicable rights plan, each Fixed Conversion Rate will be adjusted at the time of separation as if we distributed to all or substantially all holders of our ordinary shares, shares of our share capital, evidences of indebtedness, assets, property, rights, options or warrants as described in clause (3) above, subject to readjustment in the event of the expiration, termination or redemption of such rights. We do not currently have a shareholder rights plan in effect.

Adjustments to the Fixed Conversion Rates will be calculated to the nearest 1/10,000th of an ordinary share. No adjustment to any Fixed Conversion Rate will be required unless the adjustment would require an increase or decrease of at least 1% to each of the Fixed Conversion Rates; provided that if an adjustment is not made because the adjustment does not change each of the Fixed Conversion Rates by at least 1%, then such adjustment will be carried forward and taken into account in any future adjustment. Notwithstanding the foregoing, on each date for determining the number of ordinary shares issuable to a holder upon any conversion of the Mandatory Convertible Preferred Shares we will give effect to all adjustments that we have otherwise deferred pursuant to this sentence, and those adjustments will no longer be carried forward and taken into account in any future adjustment.

The Fixed Conversion Rates will not be adjusted:

S-59

Table of Contents

Except as otherwise provided above, we will be responsible for making all calculations called for under the Mandatory Convertible Preferred Shares. These calculations include, but are not limited to, determinations of the Fundamental Change Share Price, the VWAPs, the Average VWAPs and the Fixed Conversion Rates of the Mandatory Convertible Preferred Shares. We will make these calculations in good faith and, absent manifest error, our calculations will be final and binding.

We will be required, reasonably promptly after the Fixed Conversion Rates are adjusted, to provide or cause to be provided written notice of the adjustment to the holders of the Mandatory Convertible Preferred Shares. We will also be required to deliver a statement setting forth in reasonable detail the method by which the adjustment to each Fixed Conversion Rate was determined and setting forth each adjusted Fixed Conversion Rate.

For the avoidance of doubt, if an adjustment is made to the Fixed Conversion Rates, no separate inversely proportionate adjustment will be made to the Initial Price or the Threshold Appreciation Price because the Initial Price is equal to $100.00 divided by the Maximum Conversion Rate (as adjusted in the manner described herein) and the Threshold Appreciation Price is equal to $100.00 divided by the Minimum Conversion Rate (as adjusted in the manner described herein).

Whenever the terms of the Mandatory Convertible Preferred Shares require us to calculate the VWAP per ordinary share over a span of multiple days, we will make appropriate adjustments in good faith (including, without limitation, to the Applicable Market Value, the Early Conversion Average Price, the Fundamental Change Share Price and the Average Price (as the case may be)) to account for any adjustments to the Fixed Conversion Rates (as the case may be) that become effective, or any event that would require such an adjustment if the record date, ex-date, effective date or Expiration Date (as the case may be) of such event occurs, during the relevant period used to calculate such prices or values (as the case may be).

If:

then we will deem the holders of the Mandatory Convertible Preferred Shares to be holders of record of our ordinary shares for purposes of that dividend or distribution. In this case, the holders of the Mandatory Convertible Preferred Shares would receive the dividend or distribution on our ordinary shares together with the number of our ordinary shares issuable upon mandatory conversion of the Mandatory Convertible Preferred Shares.

Recapitalizations, Reclassifications and Changes of Our Ordinary Shares

In the event of:

in each case, as a result of which our ordinary shares would be converted into, or exchanged for, stock, other securities or other property or assets (including cash or any combination thereof) (each, a “Reorganization Event”), each Mandatory Convertible Preferred Share outstanding immediately prior to such Reorganization Event shall, without the consent of the holders of the Mandatory Convertible Preferred Shares, become convertible into the kind of stock, other securities or other property or assets (including cash or any combination thereof) that such holder would have been entitled to receive if such holder had converted its Mandatory Convertible Preferred Shares into ordinary shares immediately prior to such Reorganization Event (such stock, other securities or other property or assets (including cash or any combination thereof), the “Exchange Property,” with each “Unit of Exchange Property” meaning the kind and amount of Exchange Property that a holder of one ordinary share is entitled to receive), and, at the effective time of such Reorganization Event, we may amend the Statement of Rights without the consent of the holders of the Mandatory Convertible Preferred Shares to provide for such change in the convertibility of the Mandatory Convertible Preferred Shares.

If the transaction causes our ordinary shares to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of shareholder election), the Exchange Property into which the Mandatory Convertible Preferred Shares will be convertible will be deemed to be the weighted average of the types and amounts of consideration actually received by the holders of our ordinary shares in such Reorganization Event.

The number of Units of Exchange Property we will deliver upon conversion of each Mandatory Convertible Preferred Share or as a payment of dividends on the Mandatory Convertible Preferred Shares, as applicable, following the effective date of such Reorganization Event will be determined as if references to our ordinary shares in the description of the conversion rate applicable upon mandatory conversion, conversion at the option of the holder or conversion at the option of the holder upon a Fundamental Change and/or the description of the relevant dividend payment provisions, as the case may be, were to Units of Exchange Property (without interest thereon and without any right to dividends or distributions thereon which have a record date prior to the date on which holders of the Mandatory Convertible Preferred Shares become holders of record of the underlying ordinary shares). For the purpose of determining which bullet of the definition of conversion rate in the second paragraph under “—Mandatory Conversion” will apply upon mandatory conversion, and for the purpose of calculating the conversion rate if the second bullet is applicable, the value of a Unit of Exchange Property will be determined in good faith by us (which determination will be final), except that if a Unit of Exchange Property includes common equity or American Depositary Receipts (“ADRs”), that are traded on a U.S. national securities exchange, the value of such common equity or ADRs will be the average over the 20 consecutive Trading Day period used for calculating the Applicable Market Value of the volume-weighted average prices for such common equity or ADRs, as displayed on the applicable Bloomberg screen (as determined in good faith by us (which determination will be final)); or, if such price is not available, the average market value per share of such common equity or ADRs over

S-61

Table of Contents

such period as determined, using a volume-weighted average method, by a nationally recognized independent investment banking firm retained by us for this purpose. The provisions of this paragraph will apply to successive Reorganization Events, and the provisions summarized under “—Anti-dilution Adjustments” will apply to any shares of common equity or ADRs of us or any successor received by the holders of our ordinary shares in any such Reorganization Event. We (or any successor to us) will, as soon as reasonably practicable (but in any event within 20 calendar days) after the occurrence of any Reorganization Event provide written notice to the holders of the Mandatory Convertible Preferred Shares of such occurrence and of the kind and amount of cash, securities or other property that constitute the Exchange Property. Failure to deliver such notice will not affect the operation of the provisions described in this section.

It is possible that certain consolidations, mergers, combinations or other transactions could result in tax gains or losses to the holders either as a result of the transaction or the conversion thereafter. Holders are encouraged to consult with their own tax advisors regarding the tax consequences of the ownership, disposition and conversion of the Mandatory Convertible Preferred Shares.

Reservation of Shares

We will at all times reserve and keep available out of our authorized and unissued ordinary shares, solely for issuance upon conversion of the Mandatory Convertible Preferred Shares, the maximum number of our ordinary shares as shall be issuable from time to time upon the conversion of all the Mandatory Convertible Preferred Shares then outstanding.

Transfer Agent, Registrar and Conversion and Dividend Disbursing Agent

Computershare Trust Company, N.A. is the transfer agent and registrar of our ordinary shares and will serve as transfer agent, registrar, conversion and dividend disbursing agent for the Mandatory Convertible Preferred Shares.

Book-Entry, Delivery and Form

The Mandatory Convertible Preferred Shares will be issued in global form. DTC or its nominee will be the sole registered holder of the Mandatory Convertible Preferred Shares. Ownership of beneficial interests in the Mandatory Convertible Preferred Shares in global form will be limited to persons who have accounts with DTC (“participants”), or persons who hold interests through such participants. Ownership of beneficial interests in the Mandatory Convertible Preferred Shares in global form will be shown on, and the transfer of that 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).

So long as DTC, or its nominee, is the registered owner or holder of a global certificate representing the Mandatory Convertible Preferred Shares, DTC or such nominee, as the case may be, will be considered the sole holder of the Mandatory Convertible Preferred Shares represented by such global certificate for all purposes under the Statement of Rights establishing the terms of the Mandatory Convertible Preferred Shares. No beneficial owner of an interest in the Mandatory Convertible Preferred Shares in global form will be able to transfer that interest except in accordance with the applicable procedures of DTC in addition to those provided for under the Statement of Rights establishing the terms of the Mandatory Convertible Preferred Shares.

Payments of dividends on the global certificate representing the Mandatory Convertible Preferred Shares will be made to DTC or its nominee, as the case may be, as the registered holder thereof.

S-62

Table of Contents

None of us, the transfer agent, registrar, conversion or dividend disbursing agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a global certificate representing the Mandatory Convertible Preferred Shares or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

We expect that DTC or its nominee, upon receipt of any payment of dividends in respect of a global certificate representing the Mandatory Convertible Preferred Shares, will credit participants’ accounts with payments in amounts proportionate to their respective beneficial ownership interests in the aggregate Liquidation Preference of such global certificate representing the Mandatory Convertible Preferred Shares as shown on the records of DTC or its nominee, as the case may be. We also expect that payments by participants to owners of beneficial interests in such global certificate representing the Mandatory Convertible Preferred Shares held through such participants will be governed by standing instructions and customary practices, 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 in accordance with DTC rules and will be settled in same-day funds. We understand that DTC is:

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:

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 is expected to follow the foregoing procedures in order to facilitate transfers of interests in a global security among its participants, it is under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time. None of us, the transfer agent, registrar, conversion or dividend disbursing agent 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.

If DTC is at any time unwilling or unable to continue as a depositary for the Mandatory Convertible Preferred Shares in global form or DTC ceases to be registered as a clearing agency under the Exchange Act, and in either case a successor depositary is not appointed by us within 90 days, we will issue certificated shares in exchange for the global securities. Beneficial interests in

Mandatory Convertible Preferred Shares in global form held by any direct or indirect participant may also be exchanged for certificated shares upon request to DTC by such direct participant (for itself or on behalf of an indirect participant), to the transfer agent in accordance with their respective customary procedures.

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 Mandatory Convertible Preferred Shares. The information presented under the caption “Irish Tax Considerations” below is a discussion of Aptiv PLC’s status as a resident of Ireland for Irish tax purposes and of the material Irish tax consequences of investing in the Mandatory Convertible Preferred Shares. 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 Mandatory Convertible Preferred Shares.

You should consult your tax adviser regarding the applicable tax consequences to you of investing in the Mandatory Convertible Preferred Shares 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 material Irish tax considerations for certain Non-Irish Holders (as defined below) of acquiring, owning and disposing of Mandatory Convertible Preferred Shares and any ordinary shares received upon conversion. A “Non-Irish Holder” is an individual beneficial owner of Mandatory Convertible Preferred Shares or ordinary shares that is neither a resident nor ordinarily a resident in Ireland for Irish tax purposes and does not hold Mandatory Convertible Preferred Shares or ordinary shares in connection with a trade carried on by such person through an Irish branch or agency. The summary does not purport to be a comprehensive description of all of the Irish tax considerations that may be relevant to each Non-Irish Holder. The summary is based upon Irish tax laws and the practice of the Irish Revenue Commissioners in effect on the date of this prospectus supplement. Changes in law and/or administrative practice may result in a change in the Irish tax considerations described below, possibly with retrospective effect.

The summary does not constitute tax advice and is intended only as a general guide. The summary is not exhaustive and shareholders should consult their tax advisors about the Irish tax consequences (and tax consequences under the laws of other relevant jurisdictions) of the acquisition, ownership and disposal of Mandatory Convertible Preferred Shares and ordinary shares. The summary applies only to Non-Irish Holders who hold their Mandatory Convertible Preferred Shares or ordinary shares, and will own Mandatory Convertible Preferred Shares or ordinary shares, as capital assets and does not apply to other categories of Non-Irish Holders, such as dealers in securities, trustees and Non-Irish Holders who acquired their Mandatory Convertible Preferred Shares or ordinary shares or who have, or who are deemed to have, acquired their Mandatory Convertible Preferred Shares or ordinary shares by virtue of an Irish office or employment (performed or carried on to any extent in Ireland). Shareholders who are not Non-Irish Holders should consult their tax advisors about the Irish tax consequences of the acquisition, ownership and disposal of Mandatory Convertible Preferred Shares and ordinary shares.

Stamp Duty

Irish stamp duty will not apply on the issue of Mandatory Convertible Preferred Shares or to transfers of Mandatory Convertible Preferred Shares or ordinary shares on the NYSE. Irish stamp duty will not apply on the conversion of Mandatory Convertible Preferred Shares into ordinary shares.

Withholding Tax on Distributions

Distributions made by the Company will, in the absence of one of many exemptions, be subject to dividend withholding tax (“DWT”), currently at a rate of 25%.

S-65

Table of Contents

For DWT and Irish income tax purposes, a distribution includes any distribution that may be made by the Company to its shareholders, including cash dividends, non-cash dividends and additional stock taken in lieu of a cash dividend. In addition, if, as a result of an adjustment (or failure to make an adjustment) of the conversion rate for the Mandatory Convertible Preferred Shares, a shareholder’s proportionate interest in the Company’s assets or earnings and profits is increased, such shareholder may be deemed to have received for DWT and Irish income tax purposes a taxable distribution without the receipt of any cash. Where an exemption from DWT does not apply in respect of a distribution made to a particular shareholder, the Company is responsible for withholding DWT prior to making such distribution.

Non-Irish Holders that are resident in the United States, any European Union member state or any other country with which Ireland has signed a double tax agreement (an “Exempt Territory”) are likely to be entitled to an exemption from DWT provided such shareholders are beneficially entitled to the distribution and have furnished valid Irish DWT forms. Non-Irish Holders who hold their Mandatory Convertible Preferred Shares or ordinary shares through the Depository Trust Company (“DTC”) and are resident in the United States can alternatively furnish valid W-9 forms which show a valid U.S. address to their broker before the record date for any distribution, to receive such distributions without suffering DWT.

It is strongly recommended that Non-Irish Holders who are residents of Exempt Territories complete, where necessary, valid Irish DWT forms or W-9 forms and provide them, in the case of Mandatory Convertible Preferred Shares or ordinary shares not held through DTC, to the Company’s transfer agent or, in the case of Mandatory Convertible Preferred Shares or ordinary shares held through DTC, their broker, as soon as possible after receiving their Mandatory Convertible Preferred Shares or ordinary shares.

If any Non-Irish Holder who is resident in an Exempt Territory receives a distribution from which DWT has been withheld, the Non-Irish Holder may be entitled to claim a refund of DWT from the Irish Revenue Commissioners, provided the Non-Irish Holder is beneficially entitled to the distribution.

Other Non-Irish Holders of Mandatory Convertible Preferred Shares or ordinary shares that are not described above may nonetheless fall within other exemptions from DWT. If any Non-Irish Holders are exempt from DWT, but receive distributions subject to DWT, such Non-Irish Holders may apply for refunds of such DWT from the Irish Revenue Commissioners provided the shareholder is beneficially entitled to the distributions.

Income Tax on Distributions Paid on Mandatory Convertible Preferred Shares or Ordinary Shares

A Non-Irish Holder that is entitled to an exemption from DWT will have no Irish income tax or universal social charge liability on a distribution from the Company.

A Non-Irish Holder that is not entitled to an exemption from DWT, and therefore is subject to DWT, generally will have no additional Irish income tax or universal social charge liability. The DWT deducted by the Company discharges the Irish income tax and universal social charge liability.

Tax on Chargeable Gains

The current rate of tax on chargeable gains (where applicable) in Ireland is 33%. Non-Irish Holders that have not used, held or acquired their Mandatory Convertible Preferred Shares for the purposes of a trade or business carried on by such Non-Irish Holder through a branch or agency in Ireland will not be within the charge to Irish Capital Gains Tax (“CGT”) on: (i) the conversion of their Mandatory Convertible Preferred Shares into ordinary shares; or (ii) the disposal of their Mandatory Convertible Preferred Shares or ordinary shares.

S-66

Table of Contents

A holder of Mandatory Convertible Preferred Shares or ordinary shares who is an individual and who is temporarily non-resident in Ireland may, under Irish anti-avoidance legislation, be liable to Irish tax on any chargeable gain realized on a disposal of Mandatory Convertible Preferred Shares or ordinary shares during the period in which such individual is non-resident.

Capital Acquisitions Tax

A gift or inheritance comprising of Mandatory Convertible Preferred Shares or ordinary shares will be within the charge to Irish capital acquisitions tax (which subject to available exemptions and reliefs is currently levied at 33%) if either (i) the disponer or the donee/successor in relation to the gift or inheritance is resident or ordinarily resident in Ireland (or in certain circumstances, if the disponer is domiciled in Ireland irrespective of his residence or that of the donee/successor) on the relevant date or (ii) if the Mandatory Convertible Preferred Shares or ordinary shares are regarded as property situate in Ireland.

A foreign domiciled individual will not be regarded as being resident or ordinarily resident in Ireland at the date of the gift or inheritance unless that individual (i) has been resident in Ireland for the five consecutive tax years immediately preceding the tax year in which the gift or inheritance is taken, and (ii) is either resident or ordinarily resident in Ireland on that date.

Neither Mandatory Convertible Preferred Shares nor ordinary shares will be regarded as property situate in Ireland as the register of the Mandatory Convertible Preferred Shares and ordinary shares will not be in Ireland.

The Irish tax considerations summarized above are for general information only. Holders of our Mandatory Convertible Preferred Shares and ordinary shares should consult with their tax advisors regarding the Irish tax consequences relating to the acquisition, ownership and disposal of our Mandatory Convertible Preferred Shares and ordinary shares.

Jersey Tax Considerations

The following summary of the anticipated treatment of the Company and holders of the Mandatory Convertible Preferred Shares (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 Mandatory Convertible Preferred Shares should consult their professional advisers on the implications of acquiring, buying, selling or otherwise disposing of the Mandatory Convertible Preferred Shares under the laws of any jurisdiction in which they may be liable to taxation.

Taxation of the Company

The Company is not regarded as resident for tax purposes in Jersey. Therefore, the Company 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 dividends on Mandatory Convertible Preferred Shares may be paid by the Company without withholding or deduction for or on account of Jersey income tax. The holders of Mandatory Convertible Preferred Shares (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 Mandatory Convertible Preferred Shares.

Stamp Duty

In Jersey, no stamp duty is levied on the issue or transfer of the Mandatory Convertible Preferred Shares except that stamp duty is payable on Jersey grants of probate and letters of administration,

S-67

Table of Contents

which will generally be required to transfer Mandatory Convertible Preferred Shares on the death of a holder of such Mandatory Convertible Preferred Shares. 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 Mandatory Convertible Preferred Shares domiciled in Jersey, or situated in Jersey in respect of a holder of Mandatory Convertible Preferred Shares 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.

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 is a description of the material U.S. federal income tax consequences to U.S. Holders (as defined below) of the ownership, disposition, and conversion of the Mandatory Convertible Preferred Shares issued pursuant to this offering and the ownership and disposition of any ordinary shares into which such Mandatory Convertible Preferred Shares may be converted. It does not set forth all tax considerations that may be relevant to a particular person’s decision to acquire Mandatory Convertible Preferred Shares. This section is general in nature and does not address tax consequences arising under any U.S. federal tax laws other than U.S. federal income tax laws (such as estate and gift tax laws) or the laws of any state, local or non U.S. taxing jurisdiction.

This section applies only to a U.S. Holder that holds Mandatory Convertible Preferred Shares or ordinary shares as “capital assets” for U.S. federal income tax purposes. In addition, it does not set forth all of the U.S. federal income tax consequences that may be relevant in light of the U.S. Holder’s particular circumstances, including alternative minimum tax consequences, the potential application of the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), known as the Medicare contribution tax and tax consequences applicable to U.S. Holders subject to special rules, such as:

S-68

Table of Contents

If an entity that is classified as a partnership for U.S. federal income tax purposes holds Mandatory Convertible Preferred Shares or ordinary shares, the U.S. federal income tax treatment of a partner will depend on the status of the partner and the activities of the partnership. Partnerships considering an investment in Mandatory Convertible Preferred Shares and partners in such partnerships should consult their tax advisers as to the particular U.S. federal income tax consequences of owning and disposing of the Mandatory Convertible Preferred Shares or ordinary shares.

This section is based on the Code, administrative pronouncements, judicial decisions, final, temporary and proposed Treasury regulations, and the income tax treaty between the Ireland and the United States (the “Treaty”) all as of the date hereof, any of which is subject to change or differing interpretations, possibly with retroactive effect.

As used herein, the term “U.S. Holder” is a holder who, for U.S. federal income tax purposes, is a beneficial owner of Mandatory Convertible Preferred Shares or ordinary shares and is eligible for the benefits of the Treaty, and who is:

U.S. Holders should consult their tax advisers concerning the U.S. federal, state, local and non-U.S. tax consequences of owning and disposing of Mandatory Convertible Preferred Shares or ordinary shares in their particular circumstances.

Taxation of Distributions

Subject to the passive foreign investment company rules described below, any distributions (which include any amounts withheld in respect of the distributions) paid on the Mandatory Convertible Preferred Shares or the ordinary shares will be treated as dividends to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles) and included in a U.S. Holder’s income on the date of the U.S. Holder’s receipt of the dividend. Any distribution in excess of current and accumulated earnings and profits will be treated first as a tax-free return of capital to the extent of the U.S. Holder’s adjusted tax basis in the Mandatory Convertible Preferred Shares or the ordinary shares, and then as capital gain. Because we do not maintain calculations of our earnings and profits in accordance with U.S. federal income tax principles, U.S. Holders should assume that any distribution by us with respect to the ordinary shares will constitute ordinary dividend income.

Subject to certain holding-period requirements, for so long as our ordinary shares and Mandatory Convertible Preferred Shares are listed on an established securities market in the United States, such as the NYSE where the ordinary shares are listed and where we currently expect the Mandatory Convertible Shares to be listed, or we are eligible for benefits under the Treaty, any dividends paid to non-corporate U.S. Holders generally will be eligible for taxation as “qualified dividend income,” which is taxable at rates not in excess of the long-term capital gain rate applicable to such U.S. Holders. Any such dividends will not be eligible for the dividends-received deduction available to U.S. corporations under the Code. U.S. Holders should consult their tax advisers regarding the availability of the reduced tax rate on dividends in their particular circumstances. For U.S. foreign tax credit purposes, any dividend generally will be treated as foreign-source dividend income and will generally constitute passive category income. U.S. Holders should consult their tax advisers regarding the availability of the U.S. foreign tax credit under their particular circumstances.

S-69

Table of Contents

If we make a distribution on our Mandatory Convertible Preferred Shares in the form of our ordinary shares, although there is some uncertainty, we believe that such distribution will be taxable for U.S. federal income tax purposes in the same manner as cash distributions described above. The amount of such distribution and a U.S. Holder’s tax basis in such ordinary shares will equal the fair market value of such ordinary shares on the distribution date, and a U.S. Holder’s holding period for such ordinary shares will begin on the day following the distribution date. Because such distribution would not give rise to any cash from which any applicable withholding tax could be satisfied, if we (or an applicable withholding agent) pay backup withholding on behalf of a U.S. Holder (because such U.S. Holder failed to establish an exemption from backup withholding), we may, at our option, or an applicable withholding agent may, withhold such taxes from the ordinary shares or current or subsequent payments of cash to such U.S. Holder.

Extraordinary Dividends

Dividends that exceed certain thresholds in relation to a U.S. Holder’s tax basis in the Mandatory Convertible Preferred Shares or ordinary shares could be characterized as “extraordinary dividends” under the Code. A non-corporate U.S. Holder that receives an extraordinary dividend will generally be required to treat any loss on the sale of our Mandatory Convertible Preferred Shares or ordinary shares as long-term capital loss to the extent of the extraordinary dividends the U.S. Holder receives that qualify for taxation at the special rates discussed above under “—Taxation of Distributions.”

Adjustments to Conversion Rate

The conversion rate of our Mandatory Convertible Preferred Shares is subject to adjustment under specified circumstances. In such circumstances, a U.S. Holder that holds our Mandatory Convertible Preferred Shares may be deemed to have received a constructive distribution if the adjustment has the effect of increasing the U.S. Holder’s proportionate interest in our assets or earnings and profits. In addition, the failure to make certain adjustments on the Mandatory Convertible Preferred Shares may cause a U.S. Holder of our ordinary shares to be deemed to have received a constructive distribution from us, even though the U.S. Holder has not received any cash or property as a result of such adjustments. Such U.S. Holder would be subject to the rules discussed above under “—Taxation of Distributions.” Adjustments to the conversion rate made pursuant to a bona fide reasonable adjustment formula which has the effect of preventing the dilution of the interest of the holders of the Mandatory Convertible Preferred Shares generally will not be deemed to result in a constructive distribution. Certain of the possible adjustments (including, without limitation, adjustments in respect of taxable dividends to our ordinary shareholders) will not qualify as being made pursuant to a bona fide reasonable adjustment formula.

If an adjustment that does not qualify as being pursuant to a bona fide reasonable adjustment formula is made, a U.S. Holder of Mandatory Convertible Preferred Shares will be deemed to have received a constructive distribution from us, even though such U.S. Holder has not received any cash or property as a result of such adjustment. The tax consequences of the receipt of a distribution from us are described above under “—Taxation of Distributions.” Because constructive distributions deemed received by a U.S. Holder would not give rise to any cash from which any applicable withholding tax could be satisfied, if we (or an applicable withholding agent) pay backup withholding on behalf of a U.S. Holder (because such U.S. Holder failed to establish an exemption from backup withholding), we may, at our option, or an applicable withholding agent may, withhold such taxes from payments of cash or the ordinary shares payable to the U.S. Holder.

Sale or Other Disposition of Our Shares

Subject to the passive foreign investment company rules discussed below, upon the sale or the other disposition of Mandatory Convertible Preferred Shares (other than pursuant to a conversion

S-70

Table of Contents

described below) or ordinary shares, a U.S. Holder generally will recognize taxable gain or loss equal to the difference, if any, between the amount realized on the sale or other disposition and the holder’s adjusted tax basis in such shares. Gain or loss recognized on the sale or other disposition generally will be capital gain or loss and will be long-term capital gain or loss if at the time of the sale or other disposition the Mandatory Convertible Preferred Shares or the ordinary shares have been held for more than one year. Any such gain or loss generally will be U.S.-source gain or loss for U.S. foreign tax credit purposes. For non-corporate taxpayers, long-term capital gains generally are eligible for reduced rates of taxation. The deductibility of capital losses may be subject to limitations.

Conversion of Mandatory Convertible Preferred Shares into Ordinary Shares

Subject to the discussions of the passive foreign investment company rules, any cash received in lieu of a fractional ordinary share, and any cash or ordinary shares received in respect of accrued and unpaid dividends or any Fundamental Change Dividend Make-whole Amount, below, a U.S. Holder generally will not recognize any gain or loss upon the conversion of our Mandatory Convertible Preferred Shares into our ordinary shares.

Any cash or ordinary shares received in respect of accrued and unpaid dividends that have been declared will be taxable as described above under “—Taxation of Distributions,” with any ordinary shares received in respect of such dividends treated as if the U.S. Holder had received cash equal to the fair market value of any such ordinary shares determined as of the date of conversion.

Any cash received upon conversion in lieu of a fractional ordinary share generally will be treated as a payment in a taxable exchange for such fractional ordinary share, and gain or loss will be recognized on the receipt of such cash in an amount equal to the difference, if any, between the amount of such cash received and the U.S. Holder’s adjusted tax basis allocable to the fractional ordinary share deemed exchanged. Any such gain or loss will be long-term capital gain or loss if the U.S. Holder has held the Mandatory Convertible Preferred Shares for more than one year at the time of conversion. Any such gain or loss generally will be U.S.-source gain or loss for U.S. foreign tax credit purposes. For non-corporate taxpayers, long-term capital gains generally are eligible for reduced rates of taxation. The deductibility of capital losses may be subject to limitations.

The tax treatment of a U.S. Holder’s receipt of any cash or ordinary shares paid upon conversion in respect of accrued and unpaid dividends that have not been declared, or paid in respect of any Fundamental Change Dividend Make-whole Amount, is uncertain. Although not free from doubt, we believe the receipt of such cash or ordinary shares should be treated as additional consideration received by the U.S. Holder upon conversion of the Mandatory Convertible Preferred Shares into ordinary shares. Accordingly, the receipt of cash should be taxable to the extent of any gain realized by the U.S. Holder. For this purpose, the amount of any such realized gain generally would equal the excess, if any, of (i) the sum of the fair market value of our ordinary shares received upon conversion (including any fractional ordinary share for which cash is received) and any cash received (other than amounts of cash or ordinary shares received in respect of accrued and unpaid dividends that have been declared, and any cash received in lieu of a fractional ordinary share, each of which will be treated as discussed above) over (ii) the U.S. Holder’s aggregate tax basis in our Mandatory Convertible Preferred Shares immediately prior to conversion. The character of any such gain recognized (which will be the lesser of such realized gain and such cash) is uncertain. If the receipt of such cash is considered to have the effect of a dividend, as determined for U.S. federal income tax purposes, any such gain (to the extent recognized) would be taxable as a dividend to the extent of our current and accumulated earnings and profits. Alternatively, such gain could be capital gain. To the extent the amount of any cash received in respect of accrued but unpaid dividends that have not been declared, or in respect of any Fundamental Change Dividend Make-whole Amount, exceeds the gain, if

any, realized by a U.S. Holder, the excess amount would not be taxable to such U.S. Holder but would reduce its adjusted tax basis in our ordinary shares received on conversion.

U.S. Holders should be aware that the tax treatment described above in respect of the payments of cash or ordinary shares made in respect of accrued and unpaid dividends that have not been declared and any Fundamental Change Make-whole Dividend Amount is not certain and may be challenged by the Internal Revenue Service (“IRS”), including on grounds that the amount received attributable to such amounts represents a taxable dividend to the extent we have earnings and profits at the time of conversion, as described above under “—Taxation of Distributions.”

Because payments of ordinary shares that are treated as dividends will not give rise to any cash from which any applicable withholding tax could be satisfied, if we (or an applicable withholding agent) pay backup withholding on behalf of a U.S. Holder (because such U.S. Holder failed to establish an exemption from backup withholding), we may, at our option, or an applicable withholding agent may, withhold such taxes from the ordinary shares or current or subsequent payments of cash to such U.S. Holder.

Except as discussed in the last sentence of this paragraph, a U.S. Holder’s aggregate tax basis in ordinary shares received upon conversion of Mandatory Convertible Preferred Shares (including any fractional ordinary share treated as received upon conversion and then exchanged for cash) will equal the U.S. Holder’s aggregate tax basis in the converted Mandatory Convertible Preferred Shares, increased by any gain recognized on the conversion and reduced by any cash received that was treated as additional consideration received in the conversion as discussed above, and the U.S. Holder’s holding period of such ordinary shares will include the U.S. Holder’s holding period of the converted Mandatory Convertible Preferred Shares. A U.S. Holder’s tax basis in ordinary shares received may be further reduced under the rules described above under “—Extraordinary Dividends.” Ordinary shares received in payment of accrued and unpaid dividends that have been declared and taxed as a dividend upon receipt, if any, will have a tax basis equal to their fair market value on the date of conversion, and a new holding period which will commence on the day after the date of conversion.

In the event a U.S. Holder’s Mandatory Convertible Preferred Shares is converted pursuant to certain transactions (including our consolidation or merger into another person), the tax treatment of such a conversion will depend upon the facts underlying the particular transaction triggering such a conversion. U.S. Holders should consult their tax advisers to determine the specific tax treatment of a conversion under such circumstances.

Passive Foreign Investment Company Rules

Under the Code, we will be a passive foreign investment company (a “PFIC”) for any taxable year in which, after the application of certain “look-through” rules with respect to subsidiaries, either (i) 75% or more of our gross income consists of “passive income,” or (ii) 50% or more of the average quarterly value of our assets consist of assets that produce, or are held for the production of, “passive income.” For purposes of the above calculations, we will be treated as if we hold our proportionate share of the assets of, and receive directly our proportionate share of the income of, any other corporation in which we directly or indirectly own at least 25%, by value, of the shares of such corporation. Passive income includes, among other things, interest, dividends, rents, certain non-active royalties and capital gains. Based on our operations, income, assets and certain estimates and projections, including as to the relative values of our assets, we do not believe that we were a PFIC in 2019 and do not expect to be a PFIC in the foreseeable future. If we were a PFIC for any taxable year during which a U.S. Holder holds Mandatory Convertible Preferred Shares or ordinary shares, we would continue to be treated as a PFIC with respect to that U.S. Holder for all succeeding years during which the U.S. Holder holds

S-72

Table of Contents

Mandatory Convertible Preferred Shares or ordinary shares, even if we ceased to meet the threshold requirements for PFIC status, unless the U.S. Holder makes a valid deemed sale or deemed dividend election under the applicable Treasury regulations with respect to its Mandatory Convertible Preferred Shares or ordinary shares.

If we were a PFIC for any taxable year during which a U.S. Holder held Mandatory Convertible Preferred Shares or ordinary shares, gain recognized by a U.S. Holder on a sale or other disposition (including certain pledges) of the Mandatory Convertible Preferred Shares or ordinary shares would be allocated ratably over the U.S. Holder’s holding period for the Mandatory Convertible Preferred Shares or ordinary shares. The amounts allocated to the taxable year of the sale or other disposition and to any year before we became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate imposed on ordinary income in effect for individuals or corporations, as appropriate, for that taxable year, and an interest charge would be imposed on the amount allocated to that taxable year. Further, to the extent that any distribution received by a U.S. Holder on its Mandatory Convertible Preferred Shares or ordinary shares exceeds 125% of the average of the annual distributions on the Mandatory Convertible Preferred Shares or ordinary shares received during the preceding three years or the U.S. Holder’s holding period, whichever is shorter, that distribution would be subject to taxation in the same manner as gain, described immediately above. Certain elections may be available to a U.S. Holder which would result in different tax consequences from those described above.

In addition, if we were a PFIC or, with respect to a particular U.S. Holder, were treated as a PFIC for the taxable year in which we paid a dividend or for the prior taxable year, the preferential dividend rates discussed above with respect to dividends paid to non-corporate U.S. Holders would not apply.

If a U.S. Holder owns Mandatory Convertible Preferred Shares or ordinary shares during any year in which we are a PFIC, the U.S. Holder generally must file annual reports, containing such information as the U.S. Treasury may require on IRS Form 8621 (or any successor form) with respect to us, with the U.S. Holder’s federal income tax return for that year, unless otherwise specified in the instructions with respect to such form.

U.S. Holders should consult their tax advisers concerning the application of the PFIC rules in their particular circumstances in the event that we are or become a PFIC.

Information Reporting and Backup Withholding

Payments of dividends and proceeds from sales or other dispositions of Mandatory Convertible Preferred Shares or ordinary shares that are made within the United States or through certain U.S.-related financial intermediaries are subject to information reporting, and may be subject to backup withholding, unless (i) the U.S. Holder is a corporation or other exempt recipient or (ii) in the case of backup withholding, the U.S. Holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the holder’s U.S. federal income tax liability and may entitle it to a refund, provided that the required information is timely furnished to the IRS.

Reporting With Respect to Foreign Financial Assets

Certain U.S. Holders who are individuals and certain entities may be required to report information relating to an interest in our ordinary shares by filing a Form 8398 with their U.S. federal income tax return, subject to certain exceptions (including an exception for ordinary shares held in accounts maintained by certain U.S. financial institutions). Failure to file a Form 8398 where required can result in significant monetary penalties and the extension of the relevant statute of limitations with respect to all or a part of the relevant U.S. tax return. U.S. Holders should consult their tax advisers regarding this reporting requirement.

UNDERWRITING

Goldman Sachs & Co. LLC is acting as representative of each of the underwriters named below. Subject to the terms and conditions set forth in an underwriting agreement among us and the underwriters, we have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from us, the number of Mandatory Convertible Preferred Shares set forth opposite its name below.

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the Mandatory Convertible Preferred Shares sold under the underwriting agreement if any of these Mandatory Convertible Preferred Shares are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or the underwriting agreement may be terminated.

In the underwriting agreement, we have agreed that we 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 underwriters are offering the Mandatory Convertible Preferred Shares, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the Mandatory Convertible Preferred Shares, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Commissions and Discounts

We have been advised by the underwriters that the underwriters propose initially to offer the Mandatory Convertible Preferred Shares to the public at the public offering price set forth on the cover page of this prospectus supplement and to dealers at that price less a concession not in excess of $                per share. After the initial offering, the underwriters may change the public offering price,

S-74

Table of Contents

concession or any other selling terms. The underwriters may offer and sell Mandatory Convertible Preferred Shares through certain of their affiliates.

The following table shows the per share and total underwriting discounts and commissions to be paid to the underwriters. The information assumes either no exercise or full exercise by the underwriters of their over-allotment option to purchase additional Mandatory Convertible Preferred Shares.

We estimate that our expenses of the offering, excluding the underwriting discounts, are $1.0 million and are payable by us.

Option to Purchase Additional Shares

We have granted the underwriters an option to purchase, exercisable within a 30-day period after the date of this prospectus supplement, up to an additional 1,500,000 Mandatory Convertible Preferred Shares from us solely to cover over-allotments, if any, at the public offering price, less the underwriting discounts. If the underwriters exercise this option, each will be obligated, subject to conditions contained in the underwriting agreement, to purchase a number of additional Mandatory Convertible Preferred Shares proportionate to that underwriter’s initial amount reflected in the above table.

No Sales of Similar Securities

We, our executive officers and directors have agreed not to sell or transfer any ordinary shares or securities convertible into, exchangeable for, or that represent the right to receive ordinary shares, for 60 days after the date of this prospectus supplement without first obtaining the written consent of Goldman Sachs & Co. LLC. Specifically, we, our executive officers and directors have agreed, with certain limited exceptions, not to offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any ordinary shares, or any options or warrants to purchase any ordinary shares or any securities that are convertible into or exchangeable for, or that represent the right to receive (other than pursuant to employee share option plans existing on, or upon the conversion or exchange of convertible or exchangeable securities outstanding as of the date of such agreement), ordinary shares. In addition, the foregoing restriction also precludes engagement in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the foregoing ordinary shares even if such ordinary shares would be disposed of by other persons. This lock-up provision applies to the ordinary shares and to securities convertible into or exchangeable for or that represent a right to receive ordinary shares. It also applies to ordinary shares owned now or acquired later by the person executing the agreement or for which the person executing the agreement has beneficial ownership within the rules and regulations of the SEC.

Notwithstanding the above, the restrictions described in the immediately preceding paragraph and contained in the lock-up agreements between the lock-up parties and Goldman Sachs & Co. LLC, as representative of the underwriters, do not apply, subject in certain cases to various conditions, to certain transactions, including (i) the sale of ordinary shares in connection with the Concurrent Ordinary Shares Offering, (ii) in connection with the establishment of any sales plan pursuant to Rule 10b5-1 under the Exchange Act; provided that no sale of ordinary shares are made pursuant to such 10b5-1 plan prior to the expiration of the lock-up period described above; (iii) the bona fide pledge by a director or officer of ordinary shares to a financial institution; (iv) the transfer of ordinary shares that

S-75

Table of Contents

such director or officer acquires in the open market following completion of this offering, (v) the transfer of ordinary shares as a bona fide gift or gifts; (vi) the transfer of ordinary shares to any trust, partnership, limited liability company or similar entity for the direct or indirect benefit of such director or officer or the immediate family of such director or officer; (vii) in the case of a corporation, limited liability company or partnership, the transfer of ordinary shares to any shareholder, member or partner of such entity or any subsidiary or other affiliate of such entity; (viii) to any beneficiary of such director or officer pursuant to a will or other testamentary document or applicable laws of descent; (ix) by operation of law, such as pursuant to a qualified domestic order, divorce settlement, divorce decree or separation agreement; (x) to the Company from an employee of the Company upon death, disability or termination of employment, in each case, of such employee; (xi) the transfer of ordinary shares to us or the withholding of ordinary shares by us to satisfy any tax obligations arising upon the vesting of equity awards outstanding on the date of this prospectus or granted hereafter in accordance with the terms of our compensation arrangements described in this prospectus; or (xii) the issuance by us of up to 5% of the outstanding ordinary shares, or securities convertible into, exercisable for, or which are otherwise exchangeable for, ordinary shares, immediately following the closing date of this offering, in acquisitions or other similar strategic transactions; provided that, in the case of any transfer pursuant to (1) clauses (iii), (v), (vi), (vii), (viii), (ix) and (xii) of this paragraph, the recipient agrees to be bound in writing by the lock-up restrictions described above; (2) clauses (ii), (iii), (v), (vi), (vii), (viii) of this paragraph, no filing by any party (donor, donee, transferor or transferee) under the Exchange Act or other public announcement is required or is made voluntarily in connection with such transfer during the lock-up period described above; (3) clauses (v), (vi), (vii), (viii) of this paragraph, any such transfer does not involve a disposition for value; and (4) clauses (ix) or (x) of this paragraph, any public reports or filings, including filings under the Exchange Act, that are required to be made in connection with such transfer will clearly indicate in the footnotes thereto the reason for such transfer pursuant to the circumstances in such clauses.

New York Stock Exchange Listing

Prior to this offering, there has been no public market for the Mandatory Convertible Preferred Shares. We intend to apply to list the Mandatory Convertible Preferred Shares on the NYSE under the symbol “APTV PR A.” See “Description of Mandatory Convertible Preferred Shares—Listing.” Our ordinary shares are listed on the NYSE under the trading symbol “APTV.”

Price Stabilization, Short Positions

Until the distribution of the Mandatory Convertible Preferred Shares is completed, SEC rules may limit underwriters and selling group members from bidding for and purchasing our ordinary shares. However, the representatives may engage in transactions that stabilize the price of the ordinary shares, such as bids or purchases to peg, fix or maintain that price.

In connection with the offering, the underwriters may purchase and sell our Mandatory Convertible Preferred Shares in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriters of a greater number of Mandatory Convertible Preferred Shares than they are required to purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ over-allotment option to purchase additional Mandatory Convertible Preferred Shares described above. The underwriters may close out any covered short position by either exercising their over-allotment option to purchase additional Mandatory Convertible Preferred Shares or purchasing Mandatory Convertible Preferred Shares in the open market. In determining the source of Mandatory Convertible Preferred Shares to close out the covered short position, the underwriters will consider, among other things, the price of Mandatory Convertible

S-76

Table of Contents

Preferred Shares available for purchase in the open market as compared to the price at which they may purchase Mandatory Convertible Preferred Shares through the option granted to them. “Naked” short sales are sales in excess of such option. The underwriters must close out any naked short position by purchasing Mandatory Convertible Preferred Shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our Mandatory Convertible Preferred Shares in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of Mandatory Convertible Preferred Shares made by the underwriters in the open market prior to the completion of the offering.

Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our ordinary shares or preventing or retarding a decline in the market price of our ordinary shares. As a result, the price of our ordinary shares may be higher than the price that might otherwise exist in the open market. The underwriters may conduct these transactions on the NYSE, in the over-the-counter market or otherwise.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our Mandatory Convertible Preferred Shares. In addition, neither we nor any of the underwriters make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

In particular, certain of the underwriters and/or their respective affiliates are parties to and are agents and/or lenders under our credit facility and receive customary compensation in connection therewith.

SPECIAL NOTE ON FORWARD-LOOKING STATEMENTS

This prospectus, including the documents incorporated by reference herein, contains forward-looking statements that reflect, when made, our current views with respect to current events and financial performance. 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 and resulting from the United Kingdom referendum held on June 23, 2016 in which voters approved an exit from the European Union, commonly referred to as “Brexit”; fluctuations in interest rates and foreign currency exchange rates; the cyclical nature of automotive sales and production; the potential disruptions in the supply of and changes in the competitive environment for raw material integral to our products; our ability to maintain contracts that are critical to our operations; potential changes to beneficial free trade laws and regulations such as the North American Free Trade Agreement; our ability to integrate and realize the benefits of recent acquisitions; our ability to achieve the intended benefits from the separation of its Powertrain Systems segment; the ability of the Company; 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, 2017, our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2018 and June 30, 2018. 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.

RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth our ratio of earnings to fixed charges for the periods indicated. The ratio of earnings to fixed charges was calculated by dividing earnings by fixed charges. Earnings were calculated by adding (1) income from continuing operations before income taxes and equity income, (2) cash dividends received from non-consolidated affiliates and other, (3) interest expense (including amortization of any debt fees and any debt discount) on debt, and (4) the interest component of rental expense. Fixed charges were calculated by adding interest expense on debt (including amortization of any debt fees and any debt discount) and the interest component of rental expense.

Table of Contents

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 October 19, 2018, there were 263,472,291 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

7

Table of Contents

two-thirds of the voting rights represented at the meeting, in person or by proxy, and voting thereon. A special resolution can only be considered if shareholders receive at least fourteen days’ prior notice of the meeting at which such resolution will be considered.

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

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

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

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

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

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

Applicability of U.K. Takeover Code.    We do not believe that the U.K. City Code on Takeovers and Mergers will apply to takeover transactions for the Company.

Preferred Shares

We have 50,000,000 authorized preferred shares. 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.

8

Table of Contents

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.

When Aptiv PLC or Aptiv Corp. 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”).

The senior indentures and the subordinated indentures are substantially identical, except for the provisions relating to subordination. See “—Subordinated Debt.”

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.

any of the subsidiary registrants under the registration statement of which this prospectus forms a part. Debt securities issued by Aptiv Corp. will be guaranteed by Aptiv PLC and may be guaranteed by any of the subsidiary registrants. The guarantees will be full and unconditional on a joint and several basis. Each of the subsidiary guarantors is 100% owned by Aptiv PLC.

Concerning the Trustee and the Registrar and Paying Agent

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

Governing Law

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

DESCRIPTION OF WARRANTS

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

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

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

14

Table of Contents

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.

The applicable supplement will describe:

FORMS OF SECURITIES

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

Global Securities

Registered Global Securities.    Aptiv PLC or Aptiv Corp. may issue the registered debt securities, warrants and units 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 trust preferred security or unit agreement. We understand that under existing industry practices, if Aptiv PLC or Aptiv Corp. 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., the trustees, the warrant agents, the unit agents or any other agent of Aptiv PLC or Aptiv Corp., agent of the trustees or agent of the warrant agents or unit agents will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

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

If the depositary for any of these securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Securities Exchange Act of 1934, and a successor depositary registered as a clearing agency under the Securities Exchange Act of 1934 is not appointed by us within 90 days, Aptiv PLC or Aptiv Corp., 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 or Aptiv Corp. 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.
