Other Events

This week AerCap Holdings N.V. (“AerCap” or “we”) received cash insurance settlement proceeds in the total amount of approximately €91 million in full settlement of our insurance claims under the insurance policies of Limited Liability Company “Nord Wind” (“Nordwind”), in respect of five aircraft owned by AerCap group entities and formerly leased to Nordwind as of February 2022.  Effective upon receipt of these insurance settlement proceeds from Limited Liability Company “Insurance Company NSK” (“NSK”), a Russian insurance company, we have released our claims against NSK, Nordwind and its international reinsurers with respect to these five aircraft.  This insurance settlement and the receipt of the settlement proceeds were approved by the U.S. Department of Commerce and the U.S. Department of the Treasury and are consistent with other applicable sanctions regimes.

In addition, at a hearing earlier this week the Commercial Court in London denied the insurers under the “War and Allied Perils” Coverage section of our contingent and possessed insurance policy (the “C&P Policy”) permission to appeal its decision of June 11, 2025, which awarded AerCap an indemnity of approximately $1 billion in respect of the aircraft and engines which AerCap and its affiliates lost in Russia following its invasion of Ukraine in February 2022.  At the same hearing this week, the Commercial Court in London also ruled that AerCap was entitled to recover interest on the June 11, 2025 judgment in the amount of approximately $234 million.

The receipt of these latest insurance settlement proceeds and the interest award bring our total pre-tax recoveries relating to the Ukraine Conflict since 2023 to approximately $2.9 billion.
