American Integrity (AII) — a supplier view for investors
American Integrity underwrites Florida homeowners and commercial property risk and monetizes by writing net premiums while transferring peak catastrophe exposure through a blended reinsurance program: traditional reinsurers, catastrophe bonds issued by its sponsored Integrity Re vehicles, participation in the Florida Hurricane Cat Fund, and captive reinsurance coverage. The company funds growth through capital markets activity (secondary equity offerings) and professional asset management of invested surplus.

How the relationship map explains the operating model
American Integrity’s public relationships show a hybrid risk-transfer posture and capital-markets dependence rather than sole reliance on traditional treaty reinsurance. Recurrent issuance through Integrity Re vehicles and a multi-year ILS placement demonstrate that the company systematically securitizes Florida named-storm risk to scale capacity and protect surplus. Simultaneously, large policy take-outs from Citizens and use of the Florida Hurricane Cat Fund imply concentration in Florida catastrophe exposure and a strategic focus on policy acquisition via state take-out programs.
Counterparty composition highlights maturity and market access: AII works with global reinsurers that front capital markets transactions, top-tier asset managers to steward invested assets, and bulge‑bracket and specialty underwriters as bookrunners for equity capital moves. These relationships produce three operational characteristics that matter for suppliers and counterparties: high counterparty criticality for reinsurance and asset management, concentration risk driven by geographic peril focus, and market-access dependency that can change funding and collateral dynamics quickly.

What investors and suppliers should act on
- Concentration is the central risk: AII’s model is growth via Citizens take‑outs and Florida homeowners lines; counterparty stress in a severe Florida season would rapidly propagate to reinsurers, ILS investors and asset managers.
- Capital markets are mission‑critical: Reinsurance capacity is provided materially through Integrity Re ILS issuances and fronting by Hannover Re; suppliers should stress‑test collateral and payment waterfalls tied to ILS triggers.
- Ratings and asset management matter operationally: Demotech/KBRA ratings and $375m run by Goldman Sachs affect collateral requirements, investment income and liquidity profiles.
