American Integrity Insurance Group, Inc. Announces Full Placement of 2025-2026 CAT XOL Reinsurance Program

American Integrity Insurance Group, Inc. (NYSE:AII) ("American Integrity" or the "Company"), a Tampa-based property and casualty insurance holding company, announced today that it has fully placed its 2025-2026 indemnity based, catastrophe excess-of-loss reinsurance program for its insurance subsidiary, American Integrity Insurance Company of Florida, Inc. ("AIICFL"), which is effective as of June 1, 2025.

Robert Ritchie, CEO of American Integrity, commented, "I am pleased to announce the successful completion of our 2025-2026 catastrophe excess of loss reinsurance program. Due to the significant growth in premium and exposure we have experienced in the past year due to our robust voluntary writings and our participation in the fourth quarter 2024 and 2025 Citizens take-out programs, we have increased our reinsurance limit by $799 million to $2.59 billion. The placement is a combination of protection provided by traditional reinsurers, Insurance Linked Securities ("ILS") investors, the Florida Hurricane Cat Fund and our captive reinsurer."

Key points of the 2025-2026 catastrophe reinsurance program include:

• The reinsurance program provides third-party coverage of $1.93 billion for a single catastrophic event. The total third-party coverage provided for all occurrences is $2.59 billion, representing an increase of $799 million or 45% over the 2024 treaty.
• The total incurred net consolidated catastrophe reinsurance premiums ceded to third parties are expected to total $433 million for the treaty year, an increase of $96 million, or 28%, over the 2024 treaty year estimate.
• The program includes multi-year indemnity coverage totaling $565 million sourced through new catastrophe bonds issued by Integrity Re III Ltd in 2025. This catastrophe bond issuance was the eighth and largest ILS transaction the Company has sponsored.
• The Company's net retention is $35 million for each of the first and second events with $10 million retained by AIICFL and an additional $25 million retained by our segregated cell captive reinsurer. Our net retention for the third and fourth event decreases to $15.8 million and $10 million respectively and is solely with AIICFL.
• Florida Hurricane Catastrophe Fund participation of 90.0%, consistent with the prior year program.
• The entire program is indemnity based, with no parametric covers. All reinsurers participating in our 2025-2026 catastrophe reinsurance program were rated A- or better by A.M. Best or were required to post collateral up to 100% of all obligations to the Company.
• The increased coverage and net retention associated with the XOL reinsurance program reflects our growth in written premium, exposure and capital.

Jon Ritchie, President of American Integrity, commented, "We are grateful for the ongoing support of the global catastrophe reinsurance community, who have been essential to Florida's ability to withstand multiple catastrophic events in recent years."
