WHERE YOU CAN FIND MORE INFORMATION; INCORPORATION BY REFERENCE

We are subject to the information reporting requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as applicable to foreign private issuers. As a foreign private issuer, we are exempt from the rules under the Exchange Act prescribing certain disclosure and procedural requirements for proxy solicitations, and our officers, directors and principal shareholders (including the selling shareholder) are exempt from the reporting and “short-swing” profit recovery provisions contained in Section 16 of the Exchange Act with respect to their purchases and sales of shares. We file with the SEC an Annual Report on Form 20-F containing financial statements audited by an independent registered public accounting firm. We also furnish reports on Form 6-K containing unaudited interim financial information for the first three quarters of each fiscal year.

The SEC maintains an Internet site that contains reports, proxy and information statements, and other information regarding issuers that file electronically with the SEC. You can review our SEC filings, including the registration statement, by accessing the SEC’s Internet site at www.sec.gov.

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 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 and the accompanying 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” herein, in the accompanying prospectus, in our 2022 Annual Report incorporated by reference herein and in any Report 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.

RISK FACTORS

Investing in our ordinary shares involves risk. Those risks are specified below and in the section captioned “Risk Factors” in Item 3 of our 2022 Annual Report and any risk factors described in any Report on Form 6-K furnished to the SEC and incorporated by reference herein. You should carefully consider those risks together with the other information contained or incorporated by reference in this prospectus supplement before deciding to invest in our ordinary shares. If any of those risks actually occurs, 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.

GE holds, and will continue to hold, a significant portion of our outstanding ordinary shares, which may limit the ability of our public shareholders to influence significant corporate decisions.

Currently, our largest shareholder is General Electric Company (together with its affiliates, “GE”), which owns approximately 33.6% of our ordinary shares. Upon completion of this offering, including the concurrent share repurchase, GE will beneficially own approximately 20.7% of our outstanding ordinary shares (approximately 18.7% if the underwriters’ option is exercised in full). The foregoing beneficial ownership percentages are based on 231,548,669 outstanding ordinary shares as of September 8, 2023.

Pursuant to the terms of the shareholders’ agreement between GE and AerCap, GE is entitled to nominate two directors for election to our board of directors for so long as it holds at least 10% of our ordinary shares. As a result of its share ownership and director nomination rights, GE may be able to significantly influence significant corporate matters and transactions, including mergers, acquisitions or dispositions, or the amendment of our articles of association. This concentration of ownership may delay, deter or prevent acts that would be favored by our public shareholders, such as a change of control transaction that would result in the payment of a premium to such shareholders.

Future sales by GE of our ordinary shares issued to GE in connection with the GECAS Transaction may negatively affect the market price of our ordinary shares.

The ordinary shares issued to GE in connection with the acquisition of GE Capital Aviation Services (the “GECAS Transaction”) were subject to a lock-up period that expired in stages over a nine to 15 month period following the completion of the GECAS Transaction. As a result, subject to compliance with applicable securities laws and regulation and, after the consummation of this offering, subject to the selling restrictions described under the caption “Underwriting—No Sales of Similar Securities,” GE is now permitted to sell the ordinary shares it holds. GE has agreed to certain selling restrictions in connection with this offering, as described herein under the caption “Underwriting—No Sales of Similar Securities,” which selling restrictions may be waived at any time by Goldman Sachs & Co. LLC, Citigroup Global Markets Inc. and any one of

S-5

Barclays Capital Inc., BofA Securities, Inc. and J.P. Morgan Securities LLC and will expire 90 days after the date of this prospectus supplement. Future sales by GE of our ordinary shares, or the perception in the market that those sales could occur, may negatively affect the price of our ordinary shares.

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.

S-6

USE OF PROCEEDS

We will not receive any proceeds from the sale of the ordinary shares offered hereby.

S-7

DIVIDEND POLICY

To date, we have not declared or paid any dividends on our ordinary shares. We intend to retain our future earnings to fund working capital, growth, debt repayments and additional share repurchases. We do not expect to pay dividends in the foreseeable future.

S-8

SELLING SHAREHOLDER

The following table sets forth information regarding the beneficial ownership of our ordinary shares as of September 8, 2023 by the selling shareholder, before and after giving effect to this offering, including the concurrent share repurchase.

UNDERWRITING

Goldman Sachs & Co. LLC, Citigroup Global Markets Inc., Barclays Capital Inc., BofA Securities, Inc. and J.P. Morgan Securities LLC are acting as representatives of the underwriters named below. Subject to the terms and conditions stated in the underwriting agreement dated                 , 2023, each underwriter named below has severally agreed to purchase, and the selling shareholder has agreed to sell to such underwriter, the number of shares set forth opposite such underwriter’s name , which includes the ordinary shares that we intend to repurchase from the underwriters pursuant to the concurrent share repurchase.

The underwriting agreement provides that the obligations of the underwriters to purchase the ordinary shares included in this offering are subject to approval of legal matters by counsel and to other conditions. The underwriters are obligated to purchase all the ordinary shares (other than those covered by the underwriters’ option to purchase additional ordinary shares described below) if they purchase any of the ordinary shares.

The selling shareholder has granted to the underwriters a 30-day option to purchase up to 4,860,000 additional ordinary shares from the selling shareholder at the public offering price less the underwriting discounts and commissions. To the extent the option is exercised, each underwriter must purchase a number of additional ordinary shares approximately proportionate to such underwriter’s initial purchase commitment. Any ordinary shares issued or sold under the option will be issued and sold on the same terms and conditions as the other ordinary shares that are the subject of this offering. The underwriters will not receive any underwriting discount for the ordinary shares being repurchased by us pursuant to the concurrent share repurchase.

Ordinary shares sold by the underwriters to the public will initially be offered at the initial public offering price set forth on the cover of this prospectus supplement. The underwriters may sell the ordinary shares to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters for whom they act as agents or to whom they may sell as principals. If all the ordinary shares are not sold at the initial offering price, the underwriters may change the offering price and the other selling terms. The following table shows the underwriting discounts and commissions that the selling shareholder is to pay to the underwriters in connection with this offering. These amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase additional ordinary shares.

We estimate that the total expenses of this offering payable by us will be $            , including certain offering expenses we have agreed to pay on behalf of the selling shareholder incurred in connection with this offering.

We and the selling shareholder have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make because of any of those liabilities.

S-12

Concurrent Share Repurchase

Subject to the completion of this offering, the underwriters have reserved, and we intend to purchase from the underwriters, 12,150,000 ordinary shares offered in this offering, plus a corresponding portion of any additional shares purchased by the underwriters pursuant to the underwriters’ option, at a price per ordinary share equal to the lesser of (i) the price at which the underwriters purchase the ordinary shares from the selling shareholder in this offering and (ii) 110% of the lesser of (x) the closing price per ordinary share as reported on the NYSE on the date of the pricing of this offering and (y) the closing price per ordinary share as reported on the NYSE on the trading date immediately prior to the pricing of this offering.

No Sales of Similar Securities

We have agreed with the underwriters 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 Goldman Sachs & Co. LLC, Citigroup Global Markets Inc. and any one of Barclays Capital Inc., BofA Securities, Inc. and J.P. Morgan Securities LLC, other than any ordinary shares issued upon the exercise of options or the vesting of equity awards granted under terms of any employee plan, benefit or compensation arrangement or employment agreement described in this prospectus supplement or the documents incorporated by reference herein. The foregoing restrictions will apply to AerCap for a period of 90 days from the date of this prospectus supplement.

General Electric Company, on behalf of itself and each of its subsidiaries (including the selling shareholder) (collectively, the “GE Restricted Parties”), has agreed with the underwriters, subject to certain customary limitations and exceptions, not to (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of any class of shares of AerCap (collectively, the “Company Securities”) or any other securities convertible into or exercisable or exchangeable for any Company Securities (collectively, the “Restricted Securities”); (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Company Securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Company Securities or such other securities, in cash or otherwise; (iii) file any registration statement with the SEC relating to the offering of any Restricted Securities; or (iv) publicly announce any intention to engage in any of the transactions described in clauses (i) through (iii) above; provided that clause (iv) will not apply to disclosure by a GE Restricted Party of its general intent with respect to its ordinary securities if such disclosure makes no reference to any specific transaction of the type described in clause (i), (ii) or (iii). The foregoing restrictions will apply to the GE Restricted Parties for a period of 90 days from the date of this prospectus supplement.

Price Stabilization, Syndicate Covering Transactions and Penalty Bids

In connection with the underwritten offering, the underwriters 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 underwriters of a greater number of shares than they are required to purchase in this offering. The underwriters 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 underwriters are 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 underwriters in the open market prior to the completion of the underwritten offering.

S-13

The underwriters may also impose a penalty bid. This occurs when a broker or dealer repays to the underwriters a portion of the underwriting discounts or commissions received by it because the underwriters have 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 NYSE, in the over-the-counter market or otherwise.

New York Stock Exchange Listing

The ordinary shares are currently listed on the NYSE under the symbol “AER.”

Electronic Offer, Sale and Distribution of Shares

The underwriters 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 websites maintained by one or more of the underwriters. Other than the prospectus supplement and accompanying prospectus in electronic format, the information on any underwriter’s website and any information contained in any other website maintained by an 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 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 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 underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non-financial activities and services. Certain of the underwriters and their respective affiliates have provided, and may in the future provide, a variety of these services to us, to persons and entities with relationships with us, to the selling shareholder and to persons and entities with relationships with the selling shareholder, for which they received or will receive customary fees and expenses. In addition, affiliates of certain of the underwriters from time to time have acted or in the future may continue to act as agents and lenders to us and our affiliates and subsidiaries under our or their respective credit facilities, for which services the affiliates of the underwriters expect to receive customary compensation. For example, an affiliate of Citigroup Global Markets Inc. serves as administrative agent and collateral agent under certain of our revolving credit facilities, and an affiliate of BofA Securities Inc. serves as an arranger and/or a lender under certain of our term loans and revolving facilities, as described in our 2022 Annual Report.

In the ordinary course of their various business activities, the underwriters and their respective affiliates, officers, directors and employees may purchase, sell or hold a broad array of investments and actively trade securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the accounts of their customers, and such investment and trading activities may involve

S-14

or relate to assets, securities and/or instruments of AerCap (directly, as collateral securing other obligations or otherwise) and/or persons and entities with relationships with us. The underwriters and their respective affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such assets, securities or instruments and may at any time hold, or recommend to clients that they should acquire, long and/or short positions in such assets, securities and instruments.

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.

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 Form 20-F for the year ended December 31, 2022 incorporated by reference herein and in our Reports on Form 6-K furnished to the SEC from time to time incorporated by reference herein.

SELLING SHAREHOLDER

We are registering the ordinary shares in order to permit the selling shareholder to offer our ordinary shares that it owns for resale from time to time. The selling shareholder beneficially owns 111,500,000 ordinary shares as of the date of this prospectus.

The following table sets forth information regarding the beneficial ownership of our ordinary shares by the selling shareholder. The selling shareholder may sell all, some or none of the ordinary shares beneficially owned by it, and therefore we cannot estimate either the number or the percentage of ordinary shares that will be beneficially owned by the selling shareholder following any offering or sale hereunder. See the section captioned “Plan of Distribution.”

9

TAX CONSIDERATIONS

Certain tax considerations relating to an investment in our ordinary shares are set forth in the section captioned “Taxation” in Item 10 of our Annual Report on Form 20-F for the fiscal year ended December 31, 2022, filed with the SEC on March 2, 2023, which report is incorporated by reference herein.

The discussions of tax considerations incorporated herein are general summaries and do 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.

10

PLAN OF DISTRIBUTION

The selling shareholder may, from time to time, sell, transfer or otherwise dispose of any or all of our ordinary shares that it owns 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 shareholder may use any one or more of the following methods when disposing of ordinary shares or interests therein:

The selling shareholder 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 shareholder 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 shareholder or borrowed from the selling shareholder 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 shareholder 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 shareholder may loan or pledge, hypothecate or grant a security interest in the ordinary shares to broker-dealers, other financial institutions or third parties

11

which in turn may resell or otherwise transfer the ordinary shares. The selling shareholder 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 shareholder 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 shareholder, 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 shareholder from the sale of the ordinary shares offered by it will be the purchase price of the ordinary shares less discounts or commissions, if any. The selling shareholder reserves 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 shareholder will pay all fees and expenses incidental to registering the ordinary shares, including any and all SEC filing or registration fees.

The selling shareholder 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 shareholder 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 shareholder 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 shareholder for the purpose of satisfying the prospectus delivery requirements of the Securities Act.

We and the selling shareholder 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 shareholder 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

AerCap is headquartered and has its principal executive offices in Ireland. 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:

(i) 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.

(ii) 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.

(iii) 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.

(iv) 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.

(v) Enforcement proceedings should be instituted in Ireland within six years of the date of judgment.

(vi) The procedural rules of the United States court must have been observed.

(vii) 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:

(i) A judgment obtained by fraud or trick will not be enforceable.

(ii) 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.

(iii) A judgment contrary to Irish public policy is not enforceable. This would include, for example, among other things: (x) a judgment obtained on foot of a contract recognized as illegal in Ireland such as a contract in restraint of trade or (y) 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).

(iv) A judgment which is inconsistent with a prior judgment of an Irish court on the same matter is not enforceable.

(v) Jurisdiction cannot be obtained by the Irish courts over non-domiciled judgment debtors in enforcement proceedings by personal service in Ireland or outside Ireland under Order 11 of the Rules of the Superior Courts.

(vi) 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

AerCap is a public limited liability company organized in the Netherlands under the Dutch Civil Code and has its statutory seat (statutaire zetel) in Amsterdam, the Netherlands.

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 final judgment for the payment of money rendered by any federal or state court in the United States in such matters cannot automatically be recognized and 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.

Enforcement of any foreign judgment in the Netherlands will be subject to the rules of Dutch Code of Civil Procedure (Wetboek van Burgerlijke Rechtsvordering). Judgments may be rendered in a foreign currency but enforcement is executed in euro at the applicable rate of exchange. Under certain circumstances, a Dutch court has the power to stay proceedings (aanhouden) or to declare that it has no jurisdiction if concurrent proceedings are being brought elsewhere.

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.
