The information in this Amendment No. 1 to Schedule 13D (this “Amendment No. 1”) amends and supplements the Schedule 13D (the “Original Schedule 13D”) filed with the U.S. Securities and Exchange Commission (the “SEC”) by General Electric Company (“GE”), GE Capital Global Holdings, LLC (“GE Capital Global Holdings”) and GE Capital US Holdings, Inc. (“GE Capital US Holdings” and, together with GE and GE Capital Global Holdings, the “Reporting Persons”) on November 10, 2021, relating to the beneficial ownership of stock, nominal value EUR 0.01 per share (the “Ordinary Shares”), of AerCap Holdings N.V., a Netherlands public limited liability company (the “Issuer”), which has its principal executive offices at AerCap House, 65 St. Stephen’s Green, Dublin D02 YX20, Ireland.

Except as set forth herein, the Original Schedule 13D remains unmodified.

The parenthetical in the third sentence of the second paragraph of Item 4 is hereby restated as follows:

(as described in Item 6 below, GE currently has the right under the Shareholders’ Agreement to nominate up to two directors to the Issuer’s board of directors; GE has nominated two such directors).

The response to Item 6 of this Amendment No. 1 is incorporated by reference herein.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

Item 5 of the Schedule 13D is hereby amended and restated as follows:

(e) Not applicable.

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERTAKINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER.

Item 6 is hereby amended and supplemented as follows:

Underwriting Agreement

On March 8, 2023, the Issuer entered into an underwriting agreement (the “Underwriting Agreement”) with GE Capital US Holdings (the “Selling Shareholder”) and Goldman Sachs & Co. LLC, Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, as representatives (collectively, the “Representatives”) of the several underwriters named therein, relating to the secondary public offering (the “Secondary Offering”) of an aggregate of 23,000,000 Ordinary Shares to be sold by the Selling Shareholder, at a price to the public of $58.50 per share. Pursuant to the Underwriting Agreement, the underwriters have an option to purchase up to an additional 3,450,000 Ordinary Shares from the Selling Shareholder within 30 days from the date of the final prospectus supplement relating to the Secondary Offering.

The foregoing description of the terms of the Underwriting Agreement does not purport to be a complete description of the rights and obligations of the parties thereunder and is qualified in its entirety by reference to Exhibit 1.1 incorporated herein by reference.

Lock-Up Agreement

On March 7, 2023, in connection with the Secondary Offering, GE, on behalf of itself and each of its subsidiaries, executed and delivered a lock-up agreement (the “Lock-Up Agreement”) to the Representatives. Pursuant to the Lock-Up Agreement and subject to specified exceptions, GE agreed not to, without the consent of the Representatives, (a) 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 class of stock of the Issuer or any other securities convertible into or exercisable or exchangeable for any of the Issuer’s securities; (b) 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 of the Issuer’s securities, whether any such transaction described (a) or (b) is to be settled by delivery of the Issuer’s securities or such other securities, in cash or otherwise; (c) file any registration statement with the SEC relating to the offering of any restricted securities; or (d) make certain public announcements with respect to any of the foregoing transactions, in cash for a period of 90 days after March 8, 2023.

The foregoing description of the terms of the Lock-Up Agreement does not purport to be a complete description of the rights and obligations of the parties thereunder and is qualified in its entirety by reference to Exhibit 99.3 incorporated herein by reference.

Share Repurchase Agreement

On March 7, 2023, the Issuer and the Selling Shareholder entered into a share repurchase agreement (the “Share Repurchase Agreement”). Pursuant to the Share Repurchase Agreement, the Issuer agreed to repurchase $500 million of Ordinary Shares from the Selling Shareholder at a price per share of $56.89 (the “Share Repurchase”), which is equal to the price paid by the Representatives to the Selling Shareholder in the Secondary Offering, subject to certain limitations. The closing of the Share Repurchase occurred substantially simultaneously with, and was conditioned upon, the closing of the Secondary Offering.

The foregoing description of the terms of the Share Repurchase Agreement does not purport to be a complete description of the rights and obligations of the parties thereunder and is qualified in its entirety by reference to Exhibit 99.2 incorporated herein by reference.
