Dividend

In connection with AerCap’s dividend policy, in April 2026, AerCap’s Board of Directors declared a quarterly cash dividend of $0.40 per share, with a payment date of June 4, 2026, to shareholders of record as of the close of business on May 13, 2026.

The dividend will be subject to Irish dividend withholding tax at a current statutory rate of 25% unless an exemption applies. Pursuant to a confirmation obtained from the Irish Revenue Commissioners, U.S. resident shareholders who hold their shares through the Depository Trust Company (“DTC”) should be exempt from Irish dividend withholding tax provided the address of the beneficial owner of the shares in the records of their broker, or otherwise provided to AerCap’s qualifying intermediary, is in the United States. The confirmation from the Irish Revenue Commissioners is operative for a period of five years until July 25, 2029. Individuals and certain corporate shareholders that are tax resident in a country (other than Ireland) which is a member of the European Union or a country with which Ireland has a double tax treaty in effect (which includes the United States) may be exempt from Irish dividend withholding tax if they provide a relevant declaration as prescribed by the Irish Revenue Commissioners establishing their exemption from Irish dividend withholding tax provided such corporate shareholder is not itself controlled by Irish tax residents.

In addition, the dividend will be subject to Dutch dividend withholding tax (currently at a rate of 15%) for persons who are resident, or deemed to be resident, in the Netherlands (“Dutch resident holders”). To confirm that a shareholder is not a Dutch resident holder, such shareholder must provide an Irish dividend withholding tax relevant declaration as prescribed by the Irish Revenue Commissioners representing that the shareholder is not a Dutch resident holder except that, pursuant to the confirmation from the Irish Revenue Commissioners referred to above, U.S. resident shareholders who hold their shares through the DTC and have a U.S. address of the beneficial owner of the shares in the records of their broker, or that has otherwise been provided to AerCap’s qualifying intermediary, need not provide this declaration form. AerCap intends to presume that shareholders who do not comply with the above requirements are Dutch resident holders.

For a further discussion of Irish and Dutch dividend withholding taxes, see “Irish tax considerations—Dividend withholding tax” and “Dutch withholding tax considerations” in Item 10 of AerCap’s Annual Report on Form 20-F for the year ended December 31, 2025, filed with the U.S. Securities and Exchange Commission on February 12, 2026. The summary provided therein is not exhaustive and shareholders should consult their own tax advisor to determine the Irish and Dutch tax consequences of the dividend in their particular circumstances.
