Adverse Development Cover Reinsurance Agreements On October 26, 2025, Everest Re and Bermuda Re (the “Ceding Companies”) entered into adverse development cover reinsurance agreements with State National Insurance Company, Inc. and MS Transverse Insurance Company. The adverse development cover reinsurance agreements are supported on a retrocessional basis by Longtail Re, an affiliate of Stone Ridge Capital. The adverse development cover reinsurance agreements are effective October 1, 2025 and cover risks arising out of the Ceding Companies’ North American Insurance and Other Segment liabilities and relating to premium earned during 2024 and prior years (the “Subject Business”). The reinsurance agreements exclude certain liabilities, including among others those related to the Ceding Companies’ Asbestos and Environmental reserves included in the Other Segment. The aggregate of the statutory reserves held for the Subject Business, pursuant to the Reinsurance Agreements, is $5.4 billion, as of September 30, 2025. The adverse development cover is composed of two layers in excess of the $5.4 billion of North America Insurance and Other segment liability subject reserves. The first layer is $700 million, upon which Everest will transfer $1.3 billion of in-the-money reserves in consideration upon closing of the transaction. The second layer is $500 million, upon which Everest will pay approximately $122 million of consideration upon closing of the transaction, which will be reported in the consolidated statement of operations for the fourth quarter of 2025. Everest will have a co-participation of $100 million in each layer.

(“AIG”) to sell the renewal rights for certain lines of commercial property and casualty insurance business written by the Company in the U.S., U.K. and Asia Pacific, for an aggregate purchase price of $252 million (the “Master Transaction Agreement”). In addition, pursuant to the Master Transaction Agreement, AIG has agreed to pay Group $30 million for certain expenses. The closing of the transaction, occurred on October 26, 2025.

Completion of the transaction will be subject to certain regulatory approvals. The purchase price under the Master Transaction Agreements is subject to adjustment such that the final purchase price will be equal to 15% of the actual premiums written for the period beginning January 1, 2025 to and including December 31, 2025, including premiums on renewed policies between November 1, 2025 and December 31, 2025.
