American Coastal Insurance Corporation

American Coastal Insurance Corporation (ACIC) is a Delaware-incorporated insurance holding company whose operating business is conducted primarily through its wholly owned subsidiary, American Coastal Insurance Company (AmCoastal). The company writes commercial property and casualty insurance focused on commercial residential risks in Florida, where it states that 100% of premiums and policies are concentrated. ACIC distributes its apartment and assisted living facility policies through Skyway Underwriters and a network of wholesale partners rather than direct retail distribution. The company previously wrote insurance outside Florida through Interboro Insurance Company, but completed the sale of that subsidiary on April 1, 2025, further concentrating the business on Florida commercial residential insurance.
