American Integrity Insurance Group, Inc. Announces Full Placement of 2026-2027 CAT XOL Reinsurance Program

American Integrity Insurance Group, Inc. (NYSE:AII) ("American Integrity," "we," "us," "our" or the "Company"), a Tampa-based property and casualty insurance holding company and one of Florida's leading providers of residential property insurance, announced today that it has fully placed its 2026-2027 indemnity based, catastrophe excess of loss reinsurance program for its insurance subsidiary, American Integrity Insurance Company ("AIIC"), which is effective as of June 1, 2026.

Jon Ritchie, President of American Integrity, commented, "I am pleased to announce the successful completion of our 2026-2027 catastrophe excess of loss reinsurance program. This year's placement benefits from meaningful risk-adjusted rate reductions at the upper end of a US property catastrophe market that was publicly expected to be priced down 15-20% for June 1 renewals, improved terms and conditions, and an improved net retention profile. Due to the continued growth in premium and exposure that we have experienced over the past year, we have increased our total third-party excess of loss reinsurance limit for all occurrences by $409.1 million, or 15.8%, to $2.99 billion, over the 2025 treaty."

Highlights of the 2026-2027 catastrophe reinsurance program include:

• The reinsurance program provides third-party coverage of $2.25 billion for a single catastrophic event.
• The total incurred net consolidated catastrophe reinsurance premiums ceded to third parties is expected to total $430 - $440 million for the 2026 treaty year.
• The first event tower, including retentions, is equal to a 1-in-130 year return period, consistent with last year's program.
• Market conditions were favorable for this year's renewal, largely as a result of a healthy reinsurance market, the success of the Florida legislative reforms and the lack of severe storm activity in 2025. Market observers have publicly stated that U.S. property catastrophe cedents are experiencing up to 20% reductions in risk-adjusted pricing, and we believe our renewal is consistent with that market dynamic. The exception is that no risk-adjusted pricing benefit was realized on the $515 million of limit purchased from the Florida Hurricane Catastrophe Fund ("FHCF") or the $565 million of multi-year bonds issued in 2025.
• The Company took advantage of the favorable pricing environment to reduce the Company's net retention exposure despite an estimated 19% growth in peak season in-force exposure versus the prior year treaty. Our first event retention will remain flat at $35 million, and our second event retention will decrease from $35 million to $20 million for named storms (with $10 million of those amounts retained by AIIC and the remainder retained by our segregated cell captive reinsurer). Our net retention for the third event decreases from $15.8 million to $10 million, our fourth event will remain flat at $10 million, and our net retention for the third and fourth event is retained by AIIC. In a four-event hurricane season, our aggregate retention has decreased from $95 million to $75 million. Additionally, our ex-Florida first storm retention decreased from $35 million to $10 million.
• The $3 billion placement is a combination of protection provided by traditional reinsurers, Insurance Linked Securities ("ILS") investors, the FHCF and our captive reinsurer. The entire program is indemnity based, with no parametric covers. All reinsurers participating in our 2026-2027 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 traditional reinsurance market represents $1.65 billion of limit, up from $1.1 billion last year. There is no material multi-year coverage in the traditional reinsurance placement.
  • The ILS market includes the $565 million catastrophe bonds issued in 2025, which expire at the end of the 2026 treaty year (May 2027), and an additional $260 million of catastrophe bonds issued in 2026 at more favorable pricing, which expire at the end of the 2028 treaty year (May 2029).
  • The FHCF provides $572 million of limit (with a participation of 90%).
