PROSPECTUS SUPPLEMENT

(To Prospectus Dated December 2, 2019)

AerCap Holdings N.V.

4,000,000 Ordinary Shares

Waha AC Coöperatief U.A. ("Waha"), a wholly owned subsidiary of Waha Capital PJSC ("Waha Capital"), and Avia Holding Limited, a wholly owned subsidiary of Waha Capital ("Avia" and, together with Waha, the "Selling Shareholders"), are offering 4,000,000 ordinary shares, par value €0.01 per share, of AerCap Holdings N.V. ("ordinary shares"). We will not receive any proceeds from the sale of the ordinary shares by the Selling Shareholders.

We have been advised by the Selling Shareholders that, contemporaneously with this offering, Avia is terminating its existing funded collar

transactions relating to our ordinary shares and that this offering and the termination of the funded collar transactions are conditioned on each other. See "Summary-Recent Developments-Terminationof Funded Collar Transactions."

In connection with this offering, we have entered into an agreement with the Selling Shareholders and Waha Capital (the "Repurchase Agreement") to repurchase 2,427,790 ordinary shares directly from Avia in a privately negotiated transaction at a purchase price per share equal to the per share price at which the underwriter will purchase the ordinary shares from the Selling Shareholders in this offering (the "Share Repurchase"). This offering is not conditioned upon the completion of the Share Repurchase, but the Share Repurchase is conditioned upon the completion of this offering. See "Summary- Recent Developments-ShareRepurchase."

Our ordinary shares are listed on The New York Stock Exchange ("NYSE") under the symbol "AER." On November 29, 2019, the closing sale price of our ordinary shares on the NYSE was $61.81 per share. You are urged to obtain current market quotations for our ordinary shares.

The underwriter has agreed to purchase the ordinary shares from the Selling Shareholders at the price of $59.66 per share, resulting in aggregate proceeds of approximately $238,640,000 to the Selling Shareholders. The underwriter may offer the ordinary shares from time to time to purchasers directly or through agents, or through brokers in brokerage transactions on the NYSE, or to dealers in negotiated transactions or in a combination of such methods of sale, at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices.

Investing in our ordinary shares involves risk. See "Risk Factors" beginning on page S-8 of this prospectus supplement and in the documents incorporated by reference herein before you make an investment in our ordinary shares.

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

The underwriter expects to deliver the ordinary shares sold in this offering on or about December 5, 2019 through the book-entry facilities of The Depository Trust Company.

FORWARD LOOKING STATEMENTS

This prospectus supplement, the accompanying prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus include "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. We have based these forward looking statements largely on our current beliefs and projections about future events and financial trends affecting our business. Many important factors, in addition to those discussed in this prospectus supplement, could cause our actual results to differ substantially from those anticipated in our forward looking statements, including, among other things:

  • the availability of capital to us and to our customers and changes in interest rates;
  • the ability of our lessees and potential lessees to make operating lease payments to us;
  • our ability to successfully negotiate aircraft purchases, sales and leases, to collect outstanding amounts due and to repossess aircraft under defaulted leases, and to control costs and expenses;
  • changes in the overall demand for commercial aircraft leasing and aircraft management services;
  • the effects of terrorist attacks on the aviation industry and on our operations;
  • the economic condition of the global airline and cargo industry and economic and political conditions;
  • development of increased government regulation, including regulation of trade and the imposition of import and export controls, tariffs and other trade barriers;
  • competitive pressures within the industry;
  • the negotiation of aircraft management services contracts;
  • regulatory changes affecting commercial aircraft operators, aircraft maintenance, engine standards, accounting standards and taxes; and
  • the risks described or referred to in "Risk Factors" in this prospectus supplement, in the accompanying prospectus, in our Annual Report on Form 20-F for the year ended December 31, 2018 and in our Reports on Form6-K furnished to the SEC from time to time.

The words "believe," "may," "will," "aim," "estimate," "continue," "anticipate," "intend," "expect" and similar words are intended to identify forward looking statements. Forward looking statements include information concerning our possible or assumed future results of operations, business strategies, financing plans, competitive position, industry environment, potential growth opportunities, the effects of future regulation and the effects of competition. Forward looking statements speak only as of the date they were made and we undertake no obligation to update publicly or to revise any forward looking statements because of new information, future events or other factors. In light of the risks and uncertainties described above, the forward looking events and circumstances described in this prospectus supplement might not occur and are not guarantees of future performance. The factors described above should not be construed as exhaustive and should be read in conjunction with the other cautionary statements and the risk factors that are included under "Risk Factors" herein, in the accompanying prospectus, in our Annual Report on Form20-F for the year ended December 31, 2018 incorporated by reference herein and in any Report on Form 6-K furnished to the SEC from time to time incorporated by reference herein.

SUMMARY

This summary highlights the information contained elsewhere in or incorporated by reference into this prospectus supplement. Because this is only a summary, it does not contain all of the information that may be important to you. You should read this entire prospectus supplement carefully together with the information incorporated by reference herein, including "Risk Factors" and the financial statements, and notes related thereto, incorporated by reference in this prospectus supplement, before making an investment decision.

Our Business

We are the global leader in aircraft leasing. We focus on acquiringin-demand aircraft at attractive prices, funding them efficiently, hedging interest rate risk prudently and using our platform to deploy these assets with the objective of delivering superior risk-adjusted returns. We believe that by applying our expertise, we will be able to identify and execute on a broad range of market opportunities that we expect will generate attractive returns for our shareholders. We are an independent aircraft lessor, and, as such, we are not affiliated with any airframe or engine manufacturer. This independence provides us with purchasing flexibility to acquire aircraft or engine models regardless of the manufacturer.

As of September 30, 2019, we owned 946 aircraft and we managed 94 aircraft. As of September 30, 2019, we also had 320 new aircraft on order, including 151 Airbus A320neo Family aircraft, 95 Boeing 737 MAX aircraft, 45 Embraer E-Jets E2 aircraft, 26 Boeing 787 aircraft, and three Airbus A350 aircraft. As of September 30, 2019, the weighted average age of our 946 owned aircraft fleet, weighted by net book value, was 6.2 years and as of September 30, 2018, the weighted average age of our 952 owned aircraft fleet, weighted by net book value, was 6.6 years. We operate our business on a global basis. As of September 30, 2019, our owned and managed aircraft were leased to approximately 200 customers in approximately 80 countries.

We have the infrastructure, expertise and resources to execute a large number of diverse aircraft transactions in a variety of market conditions. During the three months ended September 30, 2019, we executed 108 aircraft transactions. Our teams of dedicated marketing and asset trading professionals have been successful in leasing and managing our aircraft portfolio. During the three months ended September 30, 2019, our weighted average owned aircraft utilization rate was 99.8%, calculated based on the number of days each aircraft was on lease during the period, weighted by the net book value of the aircraft.

We lease most of our aircraft to airlines under operating leases. Under these leases, the lessee is responsible for the maintenance and servicing of the equipment during the lease term and we receive the benefit, and assume the risks, of the residual value of the equipment at the end of the lease.

Recent Developments

Termination of Funded Collar Transactions

We have been advised by the Selling Shareholders that, contemporaneously with this offering, Avia is terminating its existing funded collar transactions with Deutsche Bank AG, London Branch, Nomura International plc and Citibank N.A., London Branch (each, a "Collar Counterparty" and, collectively, the "Collar Counterparties") relating to our ordinary shares (the "Funded Collar Transactions") and that this offering and the termination of the Funded Collar Transactions are conditioned on each other. See "Underwriting-Terminationof Funded Collar Transactions."

Share Repurchase

In June 2019, our board of directors approved a share repurchase program authorizing total repurchases of up to $200 million of our ordinary shares (the "June Share Repurchase Program"). In November 2019, our board of directors approved a share repurchase program authorizing total repurchases of up to $200 million of our ordinary shares (the "November Share Repurchase Program" and, together with the June Share Repurchase Program, the "Share Repurchase Programs"). Repurchases under the Share Repurchase Programs may be made through open market purchases or privately negotiated transactions in accordance with applicable U.S. federal securities laws. The Share Repurchase Programs may be suspended or discontinued at any time. As of November 27, 2019, we had repurchased 2.3 million ordinary shares under the June Share Repurchase Program for approximately $123.6 million, and approximately $76.4 million remained available for repurchases under the June Share Repurchase Program. As of November 27, 2019, we had not repurchased any ordinary shares under the November Share Repurchase Program.

In connection with this offering, we have agreed to repurchase from Avia, in a privately negotiated transaction, 2,427,790 ordinary shares at a price per share equal to the price per share that the underwriter will purchase ordinary shares from the Selling Shareholders in this offering. This offering is not conditioned upon the completion of the Share Repurchase, but the Share Repurchase is conditioned upon the completion of this offering. We expect the Share Repurchase to be completed substantially concurrently with the completion of this offering. The consummation of the Share Repurchase will also be contingent on the satisfaction of certain other closing conditions. We intend to fund the Share Repurchase with cash on hand.

The Share Repurchase is being consummated pursuant to, and will count toward, the Share Repurchase Programs.

The description of, and the other information in this prospectus supplement regarding, the Share Repurchase are included in this prospectus supplement for informational purposes only. Nothing in this prospectus supplement should be construed as an offer to sell, or the solicitation of an offer to buy, any of our ordinary shares that we repurchase.

Resignation of Directors

Effective upon the sale of any ordinary shares in this offering, Salem Al Noaimi and Homaid Al Shimmari will resign from our board of

directors and the Selling Shareholders and Waha Capital will no longer have any designees on, nor the right to nominate any designees to, our board of directors pursuant to the terms of the Repurchase Agreement. See "Selling Shareholders-MaterialRelationships."

CERTAIN TAX CONSIDERATIONS

Certain Irish tax considerations relating to an investment in our ordinary shares are set forth in the section captioned "Taxation-Irishtax considerations" in Item 10 of our Annual Report on Form20-F for the fiscal year ended December 31, 2018, filed with the SEC on March 8, 2019, which report is incorporated by reference herein.

U.S. Tax Considerations

Subject to the limitations and qualifications stated herein, this discussion sets forth the material U.S. federal income tax consequences of the purchase, ownership and disposition of the ordinary shares. The discussion of the holders' tax consequences addresses only those persons that hold those ordinary shares as capital assets for U.S. federal income tax purposes and does not address the tax consequences to any special class of holder, including without limitation, holders of (directly, indirectly or constructively) 10% or more of our ordinary shares (as measured by vote or value), dealers in securities or currencies, banks, tax-exempt organizations, life insurance companies, financial institutions, broker dealers, regulated investment companies, real estate investment trusts, traders in securities that elect the mark-to-market method of accounting for their securities holdings, persons that hold securities that are a hedge or that are hedged against currency or interest rate risks or that are part of a straddle, conversion or "integrated" transaction, certain U.S. expatriates, partnerships or other entities classified as partnerships for U.S. federal income tax purposes, persons required to accelerate the recognition of any item of gross income with respect to the ordinary shares as a result of such income being recognized on an applicable financial statement and U.S. Holders whose functional currency for U.S. federal income tax purposes is not the U.S. dollar. This discussion does not address the effect of the U.S. federal alternative minimum tax or any state, local or foreign tax laws on a holder of ordinary shares. The discussion is based on the Code, its legislative history, existing and proposed regulations thereunder, published rulings and court decisions, all as currently in effect and all subject to change at any time, possibly with retroactive effect.

For purposes of this discussion, a "U.S. Holder" means a beneficial owner of ordinary shares that is for U.S. federal income tax purposes an individual citizen or resident of the U.S.; a U.S. corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States or any political subdivision thereof; a trust if the trust (i) is subject to the primary supervision of a U.S. court and one or more U.S. persons are able to control all substantial decisions of the trust; or (ii) has elected to be treated as a U.S. person; or an estate the income of which is subject to U.S. federal income tax regardless of its source. A "non-U.S. Holder" is a beneficial owner of our ordinary shares that is neither a U.S. Holder nor a partnership for U.S. federal income tax purposes.

If an entity or arrangement that is treated as a partnership for U.S. federal income tax purposes holds the shares, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and activities of the partnership. Partnerships holding shares and partners therein should consult their own tax advisors as to the particular U.S. federal income tax consequences of acquiring, owning and disposing of the shares.

Cash Dividends and Other Distributions

A U.S. Holder of ordinary shares generally will be required to treat distributions received with respect to such ordinary shares (including any amounts withheld) as dividend income to the extent of AerCap's current or accumulated earnings and profits (computed using U.S. federal income tax principles), with the excess treated as a non-taxable return of capital to the extent of the holder's adjusted tax basis in the ordinary shares and, thereafter, as capital gain, subject to the PFIC rules discussed below. Dividends paid to a U.S. Holder that is a corporation are not eligible for the dividends received deduction generally available to corporations. Current tax law provides for a maximum 20% U.S. tax rate on the dividend income of an individual U.S. Holder with respect to dividends paid by a domestic corporation or "qualified foreign corporation" if certain holding period

S-11

Table of Contents

requirements are met. A qualified foreign corporation generally includes a foreign corporation (other than a PFIC) if (i) its ordinary shares are readily tradable on an established securities market in the United States; or (ii) it is eligible for benefits under a comprehensive U.S. income tax treaty. The ordinary shares are expected to be readily traded on the NYSE. As a result, assuming we are not treated as a PFIC, we should be treated as a qualified foreign corporation with respect to dividends paid on our ordinary shares and, therefore, dividends paid to an individual U.S. Holder with respect to ordinary shares for which the requisite holding period is satisfied should be taxed at a maximum federal tax rate of 20%.

Distributions to U.S. Holders of additional ordinary shares or preemptive rights with respect to ordinary shares that are made as part of a pro rata distribution to all of our shareholders generally will not be subject to U.S. federal income tax, but in other circumstances may constitute a taxable dividend.

Distributions paid in a currency other than U.S. dollars will be included in a U.S. Holder's gross income in a U.S. dollar amount based on the spot exchange rate in effect on the date of actual or constructive receipt whether or not the payment is converted into U.S. dollars at that time. The U.S. Holder will have a tax basis in such currency equal to such U.S. dollar amount, and any gain or loss recognized upon a subsequent sale or conversion of the foreign currency for a different U.S. dollar amount will be U.S. source ordinary income or loss. If the dividend is converted into U.S. dollars on the date of receipt, a U.S. Holder generally should not be required to recognize foreign currency gain or loss in respect of the dividend income.

Subject to applicable limitations that may vary depending upon the circumstances, foreign taxes withheld from dividends on ordinary shares, to the extent the taxes do not exceed those taxes that would have been withheld had the holder been eligible for and actually claimed the benefits of any reduction in such taxes under applicable law or tax treaty, will be creditable against the U.S. Holder's federal income tax liability. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. The rules governing foreign tax credits are complex and, therefore, prospective purchasers of ordinary shares should consult their own tax advisors regarding the availability of foreign tax credits in their particular circumstances. Instead of claiming a credit, a U.S. Holder may, at his election, deduct such otherwise creditable foreign taxes in computing his taxable income, subject to generally applicable limitations under U.S. law.

A non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax on dividends paid with respect to ordinary shares unless such income is effectively connected with the conduct by the non-U.S. Holder of a trade or business within the United States.

Sale or Disposition of Ordinary Shares

A U.S. Holder generally will recognize gain or loss on the taxable sale or exchange of the ordinary shares in an amount equal to the difference between the U.S. dollar amount realized on such sale or exchange (determined in the case of shares sold or exchanged for currencies other than U.S. dollars by reference to the spot exchange rate in effect on the date of the sale or exchange or, if the ordinary shares sold or exchanged are traded on an established securities market and the U.S. Holder is a cash basis taxpayer or an electing accrual basis taxpayer, the spot exchange rate in effect on the settlement date) and the U.S. Holder's adjusted tax basis in the ordinary shares determined in U.S. dollars. The initial tax basis of the ordinary shares to a U.S. Holder will be the U.S. Holder's U.S. dollar purchase price for the shares (determined by reference to the spot exchange rate in effect on the date of the purchase, or if the shares purchased are traded on an established securities market and the U.S. Holder is a cash basis taxpayer or an electing accrual basis taxpayer, the spot exchange rate in effect on the settlement date). Assuming that AerCap is not a PFIC and has not been treated as a PFIC during your holding period for our ordinary shares, such gain or loss will be capital gain or loss and will be long-term gain or loss if the ordinary shares have been held for more than one year. Under current law, the maximum long-term capital gain rate for an individual U.S. Holder is 20%. The deductibility of capital losses is subject to limitations. Capital gain or loss, if any, recognized by a U.S. Holder generally will be treated as U.S. source income or loss for U.S. foreign tax credit purposes.

Table of Contents

A non-U.S. Holder of ordinary shares will not be subject to United States income or withholding tax on gain from the sale or other disposition of ordinary shares unless (i) such gain is effectively connected with the conduct of a trade or business within the United States; or (ii) the non-U.S. Holder is an individual who is present in the United States for at least 183 days during the taxable year of the disposition and certain other conditions are met.

Potential Application of PFIC Provisions

We do not believe we will be classified as a PFIC for 2018. We cannot yet make a determination as to whether we will be classified as a PFIC for

2019 or subsequent years. In general, a non-U.S. corporation will be classified as a PFIC for U.S. federal income tax purposes in any taxable year in which, after applying certain look-through rules, either (i) at least 75% of its gross income is "passive income;" or (ii) at least 50% of the average value of its gross assets is attributable to assets that produce "passive income" or are held for the production of "passive income." Passive income for this purpose generally includes dividends, interest, royalties, rents and gains from commodities, foreign currency and securities transactions. Certain exceptions are provided, however, for rental income derived in the active conduct of a business.

The determination as to whether a foreign corporation is a PFIC is a complex determination that is based on all of the relevant facts and circumstances and that depends on the classification of various assets and income under applicable rules. It is unclear how some of these rules apply to us. Further, this determination must be tested annually at the end of the taxable year and, while we intend to conduct our affairs in a manner that will reduce the likelihood of our becoming a PFIC, our circumstances may change or our business plan may result in our engaging in activities that could cause us to become a PFIC. Accordingly, there can be no assurance that we will not be classified as a PFIC for the current taxable year or any future taxable year.

If we are or become a PFIC in a taxable year in which we pay a dividend or the prior taxable year, the dividend rate discussed above with respect to dividends paid to non-corporate holders would not apply. If we are a PFIC, subject to the discussion of themark-to-market election and the qualified electing fund election below, a U.S. Holder of ordinary shares will be subject to additional tax and an interest charge on "excess distributions" received with respect to the ordinary shares or gains realized on the disposition of such ordinary shares. Such a U.S. Holder will have an excess distribution if distributions during any tax year exceed 125% of the average amount received during the three preceding tax years (or, if shorter, the U.S. Holder's holding period). A U.S. Holder may realize gain on an ordinary share not only through a sale or other disposition, but also by pledging the ordinary share as security for a loan or entering into certain constructive disposition transactions. To compute the tax on an excess distribution or any gain, (i) the excess distribution or gain is allocated ratably over the U.S. Holder's holding period; (ii) the amount allocated to the current tax year and amounts allocated to any year before the first year in which we are a PFIC is taxed as ordinary income in the current tax year; and (iii) the amount allocated to each previous tax year (other than any year before the first year in which we are a PFIC) is taxed at the highest applicable marginal rate in effect for that year and an interest charge is imposed to recover the deemed benefit from the deferred payment of the tax. These rules effectively prevent a U.S. Holder from treating the gain realized on the disposition of an ordinary share as capital gain.

If we are a PFIC and our ordinary shares are "regularly traded" on a "qualified exchange," a U.S. Holder may make amark-to-market election, which may mitigate the adverse tax consequences resulting from AerCap's PFIC status. The ordinary shares will be treated as "regularly traded" in any calendar year during which more than a de minimis quantity of ordinary shares are traded on a qualified exchange on at least 15 days during each calendar quarter. The NYSE, on which the ordinary shares are expected to be regularly traded, is a qualified exchange for U.S. federal income tax purposes.

If a U.S. Holder makes the mark-to-market election, for each year in which we are a PFIC the holder generally will include as ordinary income the excess, if any, of the fair market value of the ordinary shares at the end of the taxable year over their adjusted basis, and will be permitted an ordinary loss in respect of the excess, if any, of the adjusted basis of the ordinary shares over their fair market value at the end of the taxable year (but

S-13

Table of Contents

only to the extent of the net amount of previously included income as a result of the mark-to-market election). If a U.S. Holder makes the election, his basis in the ordinary shares will be adjusted to reflect any such income or loss amounts. Any gain recognized on the sale or other disposition of ordinary shares, for which the mark-to-market election has been made, will generally be treated as ordinary income.

Alternatively, if we become a PFIC in any year, a U.S. Holder of ordinary shares may wish to avoid the adverse tax consequences resulting from our PFIC status by making a qualified electing fund ("QEF") election with respect to our ordinary shares in such year. If a U.S. Holder makes a QEF election, the holder will be required to include in gross income each year (i) as ordinary income, its pro rata share of our earnings and profits in excess of net capital gains; and (ii) as long-term capital gains, its pro rata share of our net capital gains, in each case, whether or not cash distributions are actually made. The amounts recognized by a U.S. Holder making a QEF election generally are treated as income from sources outside the U.S. If, however, U.S. Holders hold at least half of the ordinary shares, a percentage of our income equal to the proportion of our income that we receive from U.S. sources will be U.S. source income for the U.S. Holders of ordinary shares. Because a U.S. Holder of shares in a PFIC that makes a QEF election is taxed currently on its pro rata share of our income, the amounts recognized will not be subject to tax when they are distributed to the U.S. Holder. An electing U.S. Holder's basis in the ordinary shares will be increased by any amounts included in income currently as described above and decreased by any amounts not subjected to tax at the time of distribution. If we are or become a PFIC, a U.S. Holder would make a QEF election in respect of its ordinary shares by attaching a properly completed IRS Form 8621 in respect of such shares to the holder's timely filed U.S. federal income tax return. For any taxable year that we determine that we are a PFIC, we will (i) provide notice of our status as a PFIC as soon as practicable following such taxable year; and (ii) comply with all reporting requirements necessary for U.S. Holders to make QEF elections, including providing to shareholders upon request the information necessary for such an election.

Although a U.S. Holder normally is not permitted to make a retroactive QEF election, a retroactive election (a "retroactive QEF election") may be made for a taxable year of the U.S. Holder (the "retroactive election year") if the U.S. Holder (i) reasonably believed that, as of the date the QEF election was due, the foreign corporation was not a PFIC for its taxable year that ended during the retroactive election year; and (ii) to the extent provided for in applicable Treasury Regulations, filed a protective statement with respect to the foreign corporation, applicable to the retroactive election year, in which the U.S. Holder described the basis for its reasonable belief and extended the period of limitation on the assessment of taxes for all taxable years of the shareholder to which the protective statement applies. If required to be filed to preserve the U.S. Holder's ability to make a retroactive QEF election, the protective statement must be filed by the due date of the investor's return (including extensions) for the first taxable year to which the statement is to apply. U.S. Holders should consult their own tax advisors regarding the advisability of filing a protective statement.

As discussed above, if we are a PFIC, a U.S. Holder of ordinary shares that makes a QEF election (including a proper retroactive QEF election) will be required to include in income currently its pro rata share of our earnings and profits whether or not we actually distribute earnings. The use of earnings to fund reserves or pay down debt or to fund other investments could result in a U.S. Holder of ordinary shares recognizing income in excess of amounts it actually receives. In addition, our income from an investment for U.S. federal income tax purposes may exceed the amount we actually receive. If we are a PFIC and a U.S. Holder makes a valid QEF election in respect of its ordinary shares, such holder may be able to elect to defer payment, subject to an interest charge for the deferral period, of the tax on income recognized on account of the QEF election. Prospective purchasers of ordinary shares should consult their own tax advisors about the advisability of making a QEF election, protective QEF election and deferred payment election.

Certain expenses of AerCap might be a miscellaneous itemized deduction if incurred by an individual. A U.S. person that owns an interest in a "pass-through entity" is treated as recognizing income in an amount corresponding to its share of any item of expense that would be a miscellaneous itemized deduction, but may not take a deduction for such amounts. If it is determined that we are a PFIC, the IRS could take the position that we are a "pass-through entity" with respect to a U.S. Holder of ordinary shares that makes a QEF election.

S-14

Table of Contents

Special rules apply to determine the foreign tax credit with respect to withholding taxes imposed on distributions on shares in a PFIC. If a U.S. Holder owns ordinary shares during any year in which we are a PFIC, such holder must file IRS Form 8621.

We urge prospective purchasers of ordinary shares to consult their own tax advisors concerning the tax considerations relevant to an investment in a PFIC, including the availability and consequences of making the mark-to-market election and QEF election discussed above.

Additional Tax on Net Investment Income

Certain U.S. Holders that are individuals, trusts or estates may be subject to a 3.8% tax, in addition to otherwise applicable U.S. federal income tax, on the lesser of (i) the U.S. Holder's "net investment income" (or undistributed "net investment income," in the case of a trust or estate) for the relevant taxable year; and (ii) the excess of the U.S. Holder's modified adjusted gross income (or adjusted gross income, in the case of a trust or estate) for the relevant taxable year above a certain threshold (which in the case of an individual ranges from $125,000 to $250,000, depending on the individual's circumstances). A U.S. Holder's "net investment income" generally includes, among other things, dividend income on and capital gain from the disposition of shares, subject to certain exceptions. If you are a U.S. Holder that is an individual, trust or estate, you should consult their own tax advisors regarding the applicability of this tax to the ordinary shares.

Information Reporting and Backup Withholding

Information reporting to the IRS generally will be required with respect to payments on the ordinary shares and proceeds of the sale of the ordinary shares paid to holders that are U.S. taxpayers, other than certain corporations and other exempt recipients. A 24% "backup" withholding tax may apply to those payments if such a holder fails to provide a taxpayer identification number to the paying agent and to certify that no loss of exemption from backup withholding has occurred. Holders that are not subject to U.S. taxation may be required to comply with applicable certification procedures to establish that they are not U.S. taxpayers in order to avoid the application of such information reporting requirements and backup withholding. The amounts withheld under the backup withholding rules are not an additional tax and may be refunded, or credited against the holder's U.S. federal income tax liability, if any, provided the required information is timely furnished to the IRS.

The above discussion is a general summary. It does not cover all tax matters that may be of importance to particular investors. All prospective investors are strongly urged to consult their own tax advisors about the tax consequences of an investment in our ordinary shares.

UNDERWRITING

Subject to the terms and conditions set forth in an underwriting agreement dated the date of this prospectus supplement, the underwriter named below has agreed to purchase, and the Selling Shareholders have agreed to sell to it, the number of our ordinary shares set forth opposite its name below:

Underwriter

Number of

Shares

Citigroup Global Markets Inc.

4,000,000

The underwriter has agreed to purchase the ordinary shares from the Selling Shareholders at the price of $59.66 per share, resulting in aggregate proceeds of approximately $238,640,000 to the Selling Shareholders. The underwriter may offer the ordinary shares from time to time to purchasers directly or through agents, or through brokers in brokerage transactions on the NYSE, or to dealers in negotiated transactions or in a combination of such methods of sale, at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. The offering of the ordinary shares by the underwriter is subject to receipt and acceptance and subject to the underwriter's right to reject any order in whole or in part.

The underwriter may effect such transactions by selling the ordinary shares to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriter and/or purchasers of ordinary shares for whom they may act as agents or to whom they may sell as principal. In connection with the underwritten offering, the difference between the price at which the underwriter purchases the ordinary shares and the price at which the underwriter resells such shares may be deemed underwriting compensation.

The underwriting agreement provides that the obligations of the underwriter to purchase the ordinary shares offered hereby pursuant to the

underwritten public offering are subject to certain conditions precedent and that the underwriter will purchase all of such ordinary shares if any of such ordinary shares are purchased.

The ordinary shares sold in this offering are expected to be ready for delivery on or about December 5, 2019, against payment in immediately available funds.

We have agreed to indemnify the underwriter and the Selling Shareholders against certain liabilities, including liabilities under the Securities Act, or to contribute payments that may be required to be made in respect of any of these liabilities.

Pursuant to the Repurchase Agreement, the Selling Shareholders will pay our expenses related to the offering, including registration fees, printing fees, and legal and accounting fees, which will be approximately $600,000.

Termination of Funded Collar Transactions

We have been advised by the Selling Shareholders that, contemporaneously with this offering, Avia is terminating its existing funded collar transactions with Deutsche Bank AG, London Branch, Nomura International plc and Citibank N.A., London Branch (each, a "Collar Counterparty" and, collectively, the "Collar Counterparties") relating to our ordinary shares (the "Funded Collar Transactions" and, such termination, the "Termination") and the Collar Counterparties are releasing the related security interest they have over our ordinary shares owned by Avia. This offering and the Termination are conditioned on each other. In connection with the Termination, the Collar Counterparties will return 5,722,733 of our ordinary shares to Avia, all of which are being sold in this offering and the Share Repurchase, and Avia will make certain cash payments to the Collar Counterparties. We have been advised by the Collar Counterparties that they do not expect to engage in any market activity in connection with the Termination or the unwind of any of their related hedge positions.

No Sales of Similar Securities

We have agreed for a period of 30 days from the date of this prospectus supplement not to (i) offer, pledge, sell, contract to sell, sell any option or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, or file with the SEC a registration statement under the Securities Act relating to, any ordinary shares or any securities convertible into or exercisable or exchangeable for ordinary shares, or publicly disclose the intention to make any offer, sale, pledge, disposition or filing, or (ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the ordinary shares or any such other securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of ordinary shares or such other securities, in cash or otherwise, without the prior written consent of the underwriter, other than any shares of our ordinary shares issued upon the exercise of options granted under terms of any employee plan, benefit or compensation arrangement or employment agreement described in the underwriting agreement and this prospectus supplement.

Price Stabilization, Short Positions and Penalty Bids

In connection with the underwritten offering, the underwriter may purchase and sell shares of our ordinary shares in the open market. These transactions may include short sales, purchases to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriter of a greater number of shares than they are required to purchase in this offering. The underwriter must close out such naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriter is concerned that there may be downward pressure on the price of the shares in the open market prior to the completion of the underwritten offering. Stabilizing transactions consist of various bids for or purchases of our ordinary shares made by the underwriter in the open market prior to the completion of the underwritten offering.

The underwriter may also impose a penalty bid. This occurs when a broker or dealer repays to the underwriter a portion of the underwriting discounts or commissions received by it because the underwriter has repurchased shares sold by or for the account of such broker or dealer in stabilizing or short covering transactions.

Purchases to cover a short position and stabilizing transactions may have the effect of preventing or slowing a decline in the market price of our ordinary shares. Additionally, these purchases, along with the imposition of the penalty bid, may stabilize, maintain or otherwise affect 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. These transactions may be effected on The New York Stock Exchange, in the over-the-counter market or otherwise.

New York Stock Exchange Listing

Our ordinary shares are listed on The New York Stock Exchange under the symbol "AER."

Electronic Offer, Sale and Distribution of Shares

The underwriter or certain securities dealers may distribute prospectus supplements and accompanying prospectuses by electronic means, such as e-mail. A prospectus supplement and accompanying prospectus in electronic format may be made available on a website maintained by the underwriter. Other than the prospectus supplement and accompanying prospectus in electronic format, the information on the underwriter's website and any information contained in any other website maintained by the underwriter is not part of the prospectus supplement or accompanying prospectus or the registration statement of which the prospectus supplement or accompanying prospectus forms a part.

Taxation

Purchasers of the shares of our ordinary shares offered in this prospectus supplement may be required to pay registration taxes, stamp taxes and other charges under the laws and practices of the country of purchase, in

S-18

addition to the offering price. Accordingly, we urge you to consult a tax advisor with respect to whether you may be required to pay those taxes or charges, as well as any other tax consequences that may arise under the laws of the country of purchase or other jurisdictions in which the purchaser of the shares is required to pay taxes.

Other Relationships

The underwriter and its affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions.

In addition, in the ordinary course of their business activities, the underwriter and its affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriter and its affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

RISK FACTORS

Investing in our ordinary shares involves risk. Before you decide to buy our ordinary shares, you should read and carefully consider the risks and uncertainties discussed in the section captioned "Risk Factors" in Item 3 of our Annual Report on Form20-F for the year ended December 31, 2018, filed with the SEC on March 8, 2019 and in Part II, Item 1A of each of our interim financial reports contained in our Current Reports on Form 6-K subsequently furnished to the SEC under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and incorporated by reference herein, as well as any risks described in any applicable prospectus supplement and any related free writing prospectus or in other documents that are incorporated by reference therein. Additional risks not currently known to us or that we currently deem immaterial may also have a material adverse effect on us. You should carefully consider the aforementioned risks together with the other information in this prospectus and incorporated by reference herein before deciding to invest in our ordinary shares. If any of those risks actually occur, our business, financial condition and results of operations could be materially and adversely affected. In that case, the trading price of our ordinary shares could decline, and you may lose all or part of your investment.

The trading price of our ordinary shares may be volatile, and purchasers of our ordinary shares could incur substantial losses.

The market price of our ordinary shares may be subject to significant fluctuations in response to actual or anticipated variations in our operating results or other factors beyond our control. In addition, the securities markets have from time to time experienced extreme price and volume fluctuations that often have been unrelated or disproportionate to the operating performance of particular companies. These broad market fluctuations, as well as general market, economic and political conditions, such as recessions, tariffs or potential application thereof, loss of investor confidence or interest rate changes, may negatively affect our business and the market price of our ordinary shares. If any of the foregoing occurs, it could cause our share price to fall and may result in purchasers of our ordinary shares losing some or all of the value of their investment in our ordinary shares.

Possible future sales may adversely affect the price of our ordinary shares.

Possible future sales of our ordinary shares in the public or private market, or the perception that these sales may occur, could cause the market price of our ordinary shares to decline. Any transaction involving newly issued ordinary shares could also result in dilution, possibly substantial, to existing shareholders. A decline in the market price of our ordinary shares or the perception of future sales may make it more difficult for us to raise capital through the sale of equity or equity-related securities in the future at a time and price favorable to us.

We do not expect to pay any dividends in the foreseeable future.

In the past we have not paid dividends on our ordinary shares. We do not currently intend to pay dividends on our ordinary shares. In addition, the terms of certain existing and any future debt agreements may preclude us from paying dividends. As a result, capital appreciation, if any, of our ordinary shares may be your sole source of gain for the foreseeable future.

If securities analysts do not publish research or reports about our business, or if they issue unfavorable commentary or negative recommendations with respect to our ordinary shares, the price of our ordinary shares could decline.

The trading market for our ordinary shares is influenced by the research and reports that equity research and other securities analysts publish about us, our business and our industry. We do not have control over these analysts. Analysts could issue negative recommendations with respect to our ordinary shares or publish other unfavorable commentary or cease publishing reports about us, our business or our industry. If one or more of

3

Table of Contents

these analysts cease coverage of us, we could lose visibility in the market. Further, one or more analysts could downgrade their evaluations of our shares. As a result of one or more of these factors, the market price of our ordinary shares could decline rapidly and our ordinary shares trading volume could be adversely affected.

Proposed changes in Irish dividend withholding tax laws may increase taxes on any dividends you may receive.

As described in the section captioned "Taxation-Irishtax considerations-Dividendwithholding tax" in Item 10 of our Annual Report on Form 20-F for the fiscal year ended December 31, 2018, Irish dividend withholding tax ("DWT") will arise in respect of dividends or other distributions we pay unless an exemption applies. Legislation has been introduced in Ireland which, if enacted, would increase the rate of DWT from 20% to 25%, effective from January 1, 2020. In addition, The Irish Revenue Commissioners have begun a consultation process with a view toward changes in the manner in which DWT is administered, effective from January 1, 2021. As described above, we do not currently intend to pay dividends on our ordinary shares. If we were to pay dividends, however, you could be subject to a higher rate of DWT if you were unable to qualify for an exemption under the law in effect at that time. For more information on the tax consequences of owning our ordinary shares under current law, see "Tax Considerations."

FORWARD LOOKING STATEMENTS

This prospectus and the documents incorporated by reference herein may contain "forward looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. We have based these forward looking statements largely on our current beliefs and projections about future events and financial trends affecting our business. Many important factors, in addition to those discussed in this prospectus, could cause our actual results to differ substantially from those anticipated in our forward looking statements, including, among other things:

  • the availability of capital to us and to our customers and changes in interest rates;
  • the ability of our lessees and potential lessees to make operating lease payments to us;
  • our ability to successfully negotiate aircraft purchases, sales and leases, to collect outstanding amounts due and to repossess aircraft under defaulted leases, and to control costs and expenses;
  • changes in the overall demand for commercial aircraft leasing and aircraft management services;
  • the effects of terrorist attacks on the aviation industry and on our operations;
  • the economic condition of the global airline and cargo industry and economic and political conditions;
  • development of increased government regulation, including regulation of trade and the imposition of import and export controls, tariffs and other trade barriers;
  • competitive pressures within the industry;
  • the negotiation of aircraft management services contracts;
  • regulatory changes affecting commercial aircraft operators, aircraft maintenance, engine standards, accounting standards and taxes; and
  • the risks described or referred to in "Risk Factors" in this prospectus or any prospectus supplement, in our Annual Report on Form20-F for the year ended December 31, 2018 and in our Reports on Form 6-K furnished to the SEC from time to time.

The words "believe," "may," "will," "aim," "estimate," "continue," "anticipate," "intend," "expect" and similar words are intended to identify forward looking statements. Forward looking statements include information concerning our possible or assumed future results of operations, business strategies, financing plans, competitive position, industry environment, potential growth opportunities, the effects of future regulation and the effects of competition. Forward looking statements speak only as of the date they were made and we undertake no obligation to update publicly or to revise any forward looking statements because of new information, future events or other factors. In light of the risks and uncertainties described above, the forward looking events and circumstances described in this prospectus might not occur and are not guarantees of future performance. The factors described above should not be construed as exhaustive and should be read in conjunction with the other cautionary statements and the risk factors that are included under "Risk Factors" in this prospectus or any prospectus supplement, in our Annual Report on Form20-F for the year ended December 31, 2018 incorporated by reference herein and in our Reports on Form 6-K furnished to the SEC from time to time incorporated by reference herein. Except as required by applicable law, we do not undertake any obligation to publicly update or review any forward looking statement, whether as a result of new information, future developments or otherwise.

The discussion of the holders' tax consequences addresses only those persons that hold those ordinary shares as capital assets for U.S. federal income tax purposes and does not address the tax consequences to any special class of holder, including without limitation, holders of (directly, indirectly or constructively) 10% or more of our ordinary shares (as measured by vote or value), dealers in securities or currencies, banks, tax-exempt organizations, life insurance companies, financial institutions, broker dealers, regulated investment companies, real estate investment trusts, traders in securities that elect the mark-to-market method of accounting for their securities holdings, persons that hold securities that are a hedge or that are hedged against currency or interest rate risks or that are part of a straddle, conversion or "integrated" transaction, certain U.S. expatriates, partnerships or other entities classified as partnerships for U.S. federal income tax purposes, persons required to accelerate the recognition of any item of gross income with respect to the ordinary shares as a result of such income being recognized on an applicable financial statement and U.S. Holders whose functional currency for U.S. federal income tax purposes is not the U.S. dollar. This discussion does not address the effect of the U.S. federal alternative minimum tax or any state, local or foreign tax laws on a holder of ordinary shares. The discussion is based on the Code, its legislative history, existing and proposed regulations thereunder, published rulings and court decisions, all as currently in effect and all subject to change at any time, possibly with retroactive effect.

For purposes of this discussion, a "U.S. Holder" means a beneficial owner of ordinary shares that is for U.S. federal income tax purposes an individual citizen or resident of the U.S.; a U.S. corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States or any political subdivision thereof; a trust if the trust (i) is subject to the primary supervision of a U.S. court and one or more U.S. persons are able to control all substantial decisions of the trust; or (ii) has elected to be treated as a U.S. person; or an estate the income of which is subject to U.S. federal income tax regardless of its source. A "non-U.S. Holder" is a beneficial owner of our ordinary shares that is neither a U.S. Holder nor a partnership for U.S. federal income tax purposes.

If an entity or arrangement that is treated as a partnership for U.S. federal income tax purposes holds the shares, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and activities of the partnership. Partnerships holding shares and partners therein should consult their own tax advisors as to the particular U.S. federal income tax consequences of acquiring, owning and disposing of the shares.

Cash Dividends and Other Distributions

A U.S. Holder of ordinary shares generally will be required to treat distributions received with respect to such ordinary shares (including any amounts withheld) as dividend income to the extent of AerCap's current or accumulated earnings and profits (computed using U.S. federal income tax principles), with the excess treated as a non-taxable return of capital to the extent of the holder's adjusted tax basis in the ordinary shares and, thereafter, as capital gain, subject to the PFIC rules discussed below. Dividends paid to a U.S. Holder that is a corporation are not eligible for the dividends received deduction generally available to corporations. Current tax law provides for a maximum 20% U.S. tax rate on the dividend income of an individual U.S. Holder with respect to dividends paid by a domestic corporation or "qualified foreign corporation" if certain holding period

11

Table of Contents

requirements are met. A qualified foreign corporation generally includes a foreign corporation (other than a PFIC) if (i) its ordinary shares are readily tradable on an established securities market in the United States; or (ii) it is eligible for benefits under a comprehensive U.S. income tax treaty. The ordinary shares are expected to be readily traded on the NYSE. As a result, assuming we are not treated as a PFIC, we should be treated as a qualified foreign corporation with respect to dividends paid on our ordinary shares and, therefore, dividends paid to an individual U.S. Holder with respect to ordinary shares for which the requisite holding period is satisfied should be taxed at a maximum federal tax rate of 20%.

Distributions to U.S. Holders of additional ordinary shares or preemptive rights with respect to ordinary shares that are made as part of a pro rata distribution to all of our shareholders generally will not be subject to U.S. federal income tax, but in other circumstances may constitute a taxable dividend.

Distributions paid in a currency other than U.S. dollars will be included in a U.S. Holder's gross income in a U.S. dollar amount based on the spot exchange rate in effect on the date of actual or constructive receipt whether or not the payment is converted into U.S. dollars at that time. The U.S. Holder will have a tax basis in such currency equal to such U.S. dollar amount, and any gain or loss recognized upon a subsequent sale or conversion of the foreign currency for a different U.S. dollar amount will be U.S. source ordinary income or loss. If the dividend is converted into U.S. dollars on the date of receipt, a U.S. Holder generally should not be required to recognize foreign currency gain or loss in respect of the dividend income.

Subject to applicable limitations that may vary depending upon the circumstances, foreign taxes withheld from dividends on ordinary shares, to the extent the taxes do not exceed those taxes that would have been withheld had the holder been eligible for and actually claimed the benefits of any reduction in such taxes under applicable law or tax treaty, will be creditable against the U.S. Holder's federal income tax liability. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. The rules governing foreign tax credits are complex and, therefore, prospective purchasers of ordinary shares should consult their own tax advisors regarding the availability of foreign tax credits in their particular circumstances. Instead of claiming a credit, a U.S. Holder may, at his election, deduct such otherwise creditable foreign taxes in computing his taxable income, subject to generally applicable limitations under U.S. law.

A non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax on dividends paid with respect to ordinary shares unless such income is effectively connected with the conduct by the non-U.S. Holder of a trade or business within the United States.

Sale or Disposition of Ordinary Shares

A U.S. Holder generally will recognize gain or loss on the taxable sale or exchange of the ordinary shares in an amount equal to the difference between the U.S. dollar amount realized on such sale or exchange (determined in the case of shares sold or exchanged for currencies other than U.S. dollars by reference to the spot exchange rate in effect on the date of the sale or exchange or, if the ordinary shares sold or exchanged are traded on an established securities market and the U.S. Holder is a cash basis taxpayer or an electing accrual basis taxpayer, the spot exchange rate in effect on the settlement date) and the U.S. Holder's adjusted tax basis in the ordinary shares determined in U.S. dollars. The initial tax basis of the ordinary shares to a U.S. Holder will be the U.S. Holder's U.S. dollar purchase price for the shares (determined by reference to the spot exchange rate in effect on the date of the purchase, or if the shares purchased are traded on an established securities market and the U.S. Holder is a cash basis taxpayer or an electing accrual basis taxpayer, the spot exchange rate in effect on the settlement date). Assuming that AerCap is not a PFIC and has not been treated as a PFIC during your holding period for our ordinary shares, such gain or loss will be capital gain or loss and will be long-term gain or loss if the ordinary shares have been held for more than one year. Under current law, the maximum long-term capital gain rate for an individual U.S. Holder is 20%. The deductibility of capital losses is subject to limitations. Capital gain or loss, if any, recognized by a U.S. Holder generally will be treated as U.S. source income or loss for U.S. foreign tax credit purposes.

12

Table of Contents

A non-U.S. Holder of ordinary shares will not be subject to United States income or withholding tax on gain from the sale or other disposition of ordinary shares unless (i) such gain is effectively connected with the conduct of a trade or business within the United States; or (ii) the non-U.S. Holder is an individual who is present in the United States for at least 183 days during the taxable year of the disposition and certain other conditions are met.

Potential Application of PFIC Provisions

We do not believe we will be classified as a PFIC for 2018. We cannot yet make a determination as to whether we will be classified as a PFIC for

2019 or subsequent years. In general, a non-U.S. corporation will be classified as a PFIC for U.S. federal income tax purposes in any taxable year in which, after applying certain look-through rules, either (i) at least 75% of its gross income is "passive income;" or (ii) at least 50% of the average value of its gross assets is attributable to assets that produce "passive income" or are held for the production of "passive income." Passive income for this purpose generally includes dividends, interest, royalties, rents and gains from commodities, foreign currency and securities transactions. Certain exceptions are provided, however, for rental income derived in the active conduct of a business.

The determination as to whether a foreign corporation is a PFIC is a complex determination that is based on all of the relevant facts and circumstances and that depends on the classification of various assets and income under applicable rules. It is unclear how some of these rules apply to us. Further, this determination must be tested annually at the end of the taxable year and, while we intend to conduct our affairs in a manner that will reduce the likelihood of our becoming a PFIC, our circumstances may change or our business plan may result in our engaging in activities that could cause us to become a PFIC. Accordingly, there can be no assurance that we will not be classified as a PFIC for the current taxable year or any future taxable year.

If we are or become a PFIC in a taxable year in which we pay a dividend or the prior taxable year, the dividend rate discussed above with respect to dividends paid to non-corporate holders would not apply. If we are a PFIC, subject to the discussion of themark-to-market election and the qualified electing fund election below, a U.S. Holder of ordinary shares will be subject to additional tax and an interest charge on "excess distributions" received with respect to the ordinary shares or gains realized on the disposition of such ordinary shares. Such a U.S. Holder will have an excess distribution if distributions during any tax year exceed 125% of the average amount received during the three preceding tax years (or, if shorter, the U.S. Holder's holding period). A U.S. Holder may realize gain on an ordinary share not only through a sale or other disposition, but also by pledging the ordinary share as security for a loan or entering into certain constructive disposition transactions. To compute the tax on an excess distribution or any gain, (i) the excess distribution or gain is allocated ratably over the U.S. Holder's holding period; (ii) the amount allocated to the current tax year and amounts allocated to any year before the first year in which we are a PFIC is taxed as ordinary income in the current tax year; and (iii) the amount allocated to each previous tax year (other than any year before the first year in which we are a PFIC) is taxed at the highest applicable marginal rate in effect for that year and an interest charge is imposed to recover the deemed benefit from the deferred payment of the tax. These rules effectively prevent a U.S. Holder from treating the gain realized on the disposition of an ordinary share as capital gain.

If we are a PFIC and our ordinary shares are "regularly traded" on a "qualified exchange," a U.S. Holder may make amark-to-market election, which may mitigate the adverse tax consequences resulting from AerCap's PFIC status. The ordinary shares will be treated as "regularly traded" in any calendar year during which more than a de minimis quantity of ordinary shares are traded on a qualified exchange on at least 15 days during each calendar quarter. The NYSE, on which the ordinary shares are expected to be regularly traded, is a qualified exchange for U.S. federal income tax purposes.

If a U.S. Holder makes the mark-to-market election, for each year in which we are a PFIC the holder generally will include as ordinary income the excess, if any, of the fair market value of the ordinary shares at the end of the taxable year over their adjusted basis, and will be permitted an ordinary loss in respect of the excess, if any, of the adjusted basis of the ordinary shares over their fair market value at the end of the taxable year (but

13

Table of Contents

only to the extent of the net amount of previously included income as a result of the mark-to-market election). If a U.S. Holder makes the election, his basis in the ordinary shares will be adjusted to reflect any such income or loss amounts. Any gain recognized on the sale or other disposition of ordinary shares, for which the mark-to-market election has been made, will generally be treated as ordinary income.

Alternatively, if we become a PFIC in any year, a U.S. Holder of ordinary shares may wish to avoid the adverse tax consequences resulting from our PFIC status by making a qualified electing fund ("QEF") election with respect to our ordinary shares in such year. If a U.S. Holder makes a QEF election, the holder will be required to include in gross income each year (i) as ordinary income, its pro rata share of our earnings and profits in excess of net capital gains; and (ii) as long-term capital gains, its pro rata share of our net capital gains, in each case, whether or not cash distributions are actually made. The amounts recognized by a U.S. Holder making a QEF election generally are treated as income from sources outside the U.S. If, however, U.S. Holders hold at least half of the ordinary shares, a percentage of our income equal to the proportion of our income that we receive from U.S. sources will be U.S. source income for the U.S. Holders of ordinary shares. Because a U.S. Holder of shares in a PFIC that makes a QEF election is taxed currently on its pro rata share of our income, the amounts recognized will not be subject to tax when they are distributed to the U.S. Holder. An electing U.S. Holder's basis in the ordinary shares will be increased by any amounts included in income currently as described above and decreased by any amounts not subjected to tax at the time of distribution. If we are or become a PFIC, a U.S. Holder would make a QEF election in respect of its ordinary shares by attaching a properly completed IRS Form 8621 in respect of such shares to the holder's timely filed U.S. federal income tax return. For any taxable year that we determine that we are a PFIC, we will (i) provide notice of our status as a PFIC as soon as practicable following such taxable year; and (ii) comply with all reporting requirements necessary for U.S. Holders to make QEF elections, including providing to shareholders upon request the information necessary for such an election.

Although a U.S. Holder normally is not permitted to make a retroactive QEF election, a retroactive election (a "retroactive QEF election") may be made for a taxable year of the U.S. Holder (the "retroactive election year") if the U.S. Holder (i) reasonably believed that, as of the date the QEF election was due, the foreign corporation was not a PFIC for its taxable year that ended during the retroactive election year; and (ii) to the extent provided for in applicable Treasury Regulations, filed a protective statement with respect to the foreign corporation, applicable to the retroactive election year, in which the U.S. Holder described the basis for its reasonable belief and extended the period of limitation on the assessment of taxes for all taxable years of the shareholder to which the protective statement applies. If required to be filed to preserve the U.S. Holder's ability to make a retroactive QEF election, the protective statement must be filed by the due date of the investor's return (including extensions) for the first taxable year to which the statement is to apply. U.S. Holders should consult their own tax advisors regarding the advisability of filing a protective statement.

As discussed above, if we are a PFIC, a U.S. Holder of ordinary shares that makes a QEF election (including a proper retroactive QEF election) will be required to include in income currently its pro rata share of our earnings and profits whether or not we actually distribute earnings. The use of earnings to fund reserves or pay down debt or to fund other investments could result in a U.S. Holder of ordinary shares recognizing income in excess of amounts it actually receives. In addition, our income from an investment for U.S. federal income tax purposes may exceed the amount we actually receive. If we are a PFIC and a U.S. Holder makes a valid QEF election in respect of its ordinary shares, such holder may be able to elect to defer payment, subject to an interest charge for the deferral period, of the tax on income recognized on account of the QEF election. Prospective purchasers of ordinary shares should consult their own tax advisors about the advisability of making a QEF election, protective QEF election and deferred payment election.

Certain expenses of AerCap might be a miscellaneous itemized deduction if incurred by an individual. A U.S. person that owns an interest in a "pass-through entity" is treated as recognizing income in an amount corresponding to its share of any item of expense that would be a miscellaneous itemized deduction, but may not take a deduction for such amounts. If it is determined that we are a PFIC, the IRS could take the position that we are a "pass-through entity" with respect to a U.S. Holder of ordinary shares that makes a QEF election.

Special rules apply to determine the foreign tax credit with respect to withholding taxes imposed on distributions on shares in a PFIC. If a U.S. Holder owns ordinary shares during any year in which we are a PFIC, such holder must file IRS Form 8621.

We urge prospective purchasers of ordinary shares to consult their own tax advisors concerning the tax considerations relevant to an investment in a PFIC, including the availability and consequences of making the mark-to-market election and QEF election discussed above.

Additional Tax on Net Investment Income

Certain U.S. Holders that are individuals, trusts or estates may be subject to a 3.8% tax, in addition to otherwise applicable U.S. federal income tax, on the lesser of (i) the U.S. Holder's "net investment income" (or undistributed "net investment income," in the case of a trust or estate) for the relevant taxable year; and (ii) the excess of the U.S. Holder's modified adjusted gross income (or adjusted gross income, in the case of a trust or estate) for the relevant taxable year above a certain threshold (which in the case of an individual ranges from $125,000 to $250,000, depending on the individual's circumstances). A U.S. Holder's "net investment income" generally includes, among other things, dividend income on and capital gain from the disposition of shares, subject to certain exceptions. If you are a U.S. Holder that is an individual, trust or estate, you should consult their own tax advisors regarding the applicability of this tax to the ordinary shares.

Information Reporting and Backup Withholding

Information reporting to the IRS generally will be required with respect to payments on the ordinary shares and proceeds of the sale of the ordinary shares paid to holders that are U.S. taxpayers, other than certain corporations and other exempt recipients. A 24% "backup" withholding tax may apply to those payments if such a holder fails to provide a taxpayer identification number to the paying agent and to certify that no loss of exemption from backup withholding has occurred. Holders that are not subject to U.S. taxation may be required to comply with applicable certification procedures to establish that they are not U.S. taxpayers in order to avoid the application of such information reporting requirements and backup withholding. The amounts withheld under the backup withholding rules are not an additional tax and may be refunded, or credited against the holder's U.S. federal income tax liability, if any, provided the required information is timely furnished to the IRS.

The above discussion is a general summary. It does not cover all tax matters that may be of importance to particular investors. All prospective investors are strongly urged to consult their own tax advisors about the tax consequences of an investment in our ordinary shares.

PLAN OF DISTRIBUTION

The Selling Shareholders may, from time to time, sell, transfer or otherwise dispose of any or all of its ordinary shares or interests in ordinary shares on any stock exchange, market or trading facility on which the ordinary shares are traded, in private transactions or a combination thereof. These dispositions may be at fixed prices, at prevailing market prices, at the time of sale at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

The Selling Shareholders may use any one or more of the following methods when disposing of ordinary shares or interests therein:

  • underwritten public offerings, pursuant to which one or more underwriters may resell the ordinary shares in one or more transactions, including in negotiated transactions at a fixed public offering price or at varying prices determined at the time of sales;
  • "at the market" to or through market makers or into an existing market for the ordinary shares;
  • ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
  • block trades in which a broker-dealer will attempt to sell the ordinary shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction;
  • purchases by the broker-dealer as principal and resale by the broker-dealer for its account;
  • an exchange distribution in accordance with the rules of the applicable exchange;
  • privately negotiated transactions;
  • through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise, or through derivative transactions or short sales;
  • in other ways not involving market makers or established trading markets, including direct sales to purchasers or sales effected through agents;
  • by pledge to secure debts and other obligations;
  • broker-dealersmay agree with the Selling Shareholders to sell a specified number of such ordinary shares at a stipulated price per share; or
  • a combination of any such methods of sale.

The Selling Shareholders may enter into derivative transactions with broker-dealers, other financial institutions or third parties or sell securities not covered by this prospectus in privately negotiated or registered transactions. These transactions may involve the sale of ordinary shares by the Selling Shareholders by forward sale or by an offering (directly or by entering into derivative transactions with broker-dealers, other financial institutions or third parties) of options, rights, warrants or other securities that are offered with, convertible into or exchangeable for ordinary shares.

If the applicable prospectus supplement indicates, in connection with derivative transactions, the broker-dealers, other financial institutions or third parties may sell ordinary shares covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the broker- dealer, other financial institution or third party may use ordinary shares pledged by the Selling Shareholders or borrowed from the Selling Shareholders or others to settle those sales or to close out any related open borrowings of ordinary shares, and may use ordinary shares received from the Selling Shareholders in settlement of derivative transactions to close out any related open borrowing of ordinary shares.

In connection with the sale of our ordinary shares, the Selling Shareholders may loan or pledge, hypothecate or grant a security interest in the ordinary shares to broker-dealers, other financial institutions or third parties

16

Table of Contents

which in turn may resell or otherwise transfer the ordinary shares. The Selling Shareholders may also enter into option or other transactions with broker- dealers, other financial institutions or third parties or enter into one or more derivative securities that in each case may involve the delivery to such broker- dealer, other financial institution or third party of ordinary shares offered by this prospectus, which may then resell or otherwise transfer the ordinary shares.

The Selling Shareholders may also enter into hedging transactions with broker-dealers or other financial institutions and the broker-dealers or other financial institutions may engage in short sales of the ordinary shares in the course of hedging the positions they assume with the Selling Shareholders, including, without limitation, in connection with distributions of the ordinary shares by those broker-dealers or other financial institutions.

This prospectus may be supplemented or amended from time to time to describe a specific plan of distribution and any related transactions.

The aggregate proceeds to the Selling Shareholders from the sale of the ordinary shares offered by them will be the purchase price of the ordinary shares less discounts or commissions, if any. The Selling Shareholders reserve the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of ordinary shares to be made directly or through agents. We will not receive any of the proceeds from any offering or sale hereunder. The Selling Shareholders will pay all fees and expenses incidental to registering the ordinary shares, including any and all SEC filing or registration fees.

The Selling Shareholders also may resell all or a portion of the ordinary shares in open market transactions in reliance upon Rule 144 under the Securities Act, provided that it meets the criteria and conforms to the requirements of that rule.

Any underwriters, broker-dealers or agents that participate in the sale of the ordinary shares or interests therein may be "underwriters" within the meaning of Section 2(a)(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the ordinary shares may be underwriting discounts and commissions under the Securities Act.

To the extent required, the ordinary shares to be sold, the respective purchase prices and public offering prices, the names of any agent, dealer or underwriter, any applicable commissions, discounts or concessions, and other terms with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

In order to comply with the securities laws of some states, if applicable, the ordinary shares may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the ordinary shares may not be sold unless they have been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

We have advised the Selling Shareholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of ordinary shares in the market and to the activities of the Selling Shareholders and its affiliates. In addition, to the extent applicable, we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the Selling Shareholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act.

We and the Selling Shareholders may enter into agreements pursuant to which underwriters, dealers and agents who participate in the distribution of the ordinary shares may be entitled to indemnification by us or the Selling Shareholders against certain liabilities, including liabilities arising under the Securities Act, and to contribution with respect to payments which the underwriters, dealers or agents may be required to make.

ENFORCEMENT OF CIVIL LIABILITY JUDGMENTS UNDER IRISH LAW

As the United States is not a party to a convention with Ireland in respect of the enforcement of judgments, common law rules apply in order to determine whether a judgment of the courts of the United States is enforceable in Ireland. A judgment of a court of the United States will be enforced by the courts in Ireland if the following general requirements are met:

  1. The United States court must have jurisdiction under Irish conflict of law rules. If the Irish courts determine that the jurisdiction of the United States court is not acceptable, then the judgment cannot be enforced or recognized in Ireland.
  2. The judgment must be final and conclusive and the decree must be final and unalterable in the court that produces it. The enforcement of a judgment under appeal in the United States will normally be stayed in Ireland pending the outcome of the appeal.
  3. When enforcing an in personam judgment (action against a specific person as opposed to a judgment specific to an asset), the amount in question must be a definite sum of money.
  4. Once the United States court is shown to have jurisdiction, the Irish courts will not examine the merits of the judgment obtained in the United States.
  5. Enforcement proceedings should be instituted in Ireland within six years of the date of judgment.
  6. The procedural rules of the United States court must have been observed.
  7. There is a practical benefit to the party in whose favor the judgment of the United States court is made in seeking to have that judgment enforced in Ireland.

There are a number of possible defenses to an application to enforce a judgment of the courts of the United States in Ireland, including the following:

  1. A judgment obtained by fraud or trick will not be enforceable.
  2. A judgment in breach of natural or constitutional justice under Irish law will not be enforceable. This would include a failure to notify the other party of the hearing or to give the other party a fair hearing.
  3. A judgment contrary to Irish public policy is not enforceable. This would include, for example, among other things (i) a judgment obtained on foot of a contract recognized as illegal in Ireland such as a contract in restraint of trade or (ii) a judgment granted on foot of foreign penal or revenue (tax) laws or expropriatory laws (the latter of which would include certain laws permitting the requisitioning or confiscation of property).
  4. A judgment which is inconsistent with a prior judgment of an Irish court on the same matter is not enforceable.
  5. Jurisdiction cannot be obtained by the Irish courts over judgment debtors in enforcement proceedings by personal service in Ireland or outside Ireland under Order 11 of the Rules of the Superior Courts.
  6. A judgment will not be enforced where such judgment is shown to be erroneous by a party to the enforcement proceedings in Ireland by such party adducing new evidence which could not have been discovered using reasonable diligence prior to obtaining the judgment in the United States.

ENFORCEMENT OF CIVIL LIABILITY JUDGMENTS UNDER DUTCH LAW

We are advised that there is no enforcement treaty between the Netherlands and the United States providing for reciprocal recognition and enforcement of judgments, other than arbitration awards, in civil and commercial matters. Therefore, a judgment rendered by any federal or state court in the United States in such matters cannot automatically be enforced in the Netherlands. An application will have to be made to the competent Dutch court in order to obtain a judgment that can be enforced in the Netherlands. The Dutch courts can in principle be expected to give conclusive effect to a final and enforceable judgment of a competent United States court in respect of the contractual obligations under the relevant document without re-examination or re-litigation, but would require (i) that the relevant court in the United States had jurisdiction in the matter in accordance with standards that are generally accepted internationally, (ii) the proceedings before such court to have complied with principles of proper procedure (behoorlijke rechtspleging), (iii) such judgment not being contrary to the public policy (openbare orde) of the Netherlands or the European Union, (iv) that recognition and/or enforcement of the judgment is not irreconcilable with a decision of a Dutch court rendered between the same parties or with an earlier decision of a foreign court rendered between the same parties in a dispute that is about the same subject matter and that is based on the same cause, provided that such earlier decision can be recognized in the Netherlands and (v) the judgment is-according to the law of its country of origin-formally capable of being enforced (e.g. is readily enforceable, has not been annulled in appeal or its enforceability has not been subject to a certain time frame), but the court will in either case have discretion to attach such weight to the judgment of any federal or state court in the United States as it deems appropriate and may re-examine or re-litigate the substantive matters adjudicated upon. Furthermore, a Dutch court may reduce the amount of damages granted by a federal or state court in the United States and recognize damages only to the extent that they are necessary to compensate actual losses or damages.

Dutch civil procedure differs substantially from U.S. civil procedure in a number of respects. Insofar as the production of evidence is concerned, U.S. law and the laws of several other jurisdictions based on common law provide for pre-trial discovery, a process by which parties to the proceedings may prior to trial compel the production of documents by adverse or third parties and the deposition of witnesses. Evidence obtained in this manner may be decisive in the outcome of any proceeding. No such pre-trial discovery process exists under Dutch law. In addition, it is doubtful whether a Dutch court would accept jurisdiction and impose civil or other liability in an original action commenced in the Netherlands and predicated solely upon United States federal securities laws.

DISCLOSURE OF SEC POSITION ON INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

Under Dutch law, AerCap is permitted to purchase directors' and officers' insurance. AerCap carries such insurance. In addition, the articles of association of AerCap include indemnification of its directors and officers against liabilities, including judgments, fines and penalties, as well as against associated reasonable legal expenses and settlement payments, to the extent this is allowed under Dutch law. To be entitled to indemnification, these persons must not have engaged in an act or omission of willful misconduct or bad faith. Insofar as such indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling AerCap pursuant to the foregoing provisions, AerCap has been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.
