E&S Property Market Share American Coastal Insurance Corporation 7 We believe the admitted market in Florida makes sense for most habitational risks due to the FHCF and the individual rating of risk over $5m of TIV. For all other states and risks that are ineligible for the FHCF in Florida or require an AM Best rated carrier, the E&S market represents the best path to sustainable underwriting profitability.

Debt • In the long-term, we plan to target ≤25% debt to total capital ratio. • We plan to reduce but not fully eliminate our long-term debt upon maturity. Equity • When management believes ACIC stock is significantly undervalued, we may participate in stock buybacks. • The Board of Directors previously authorized repurchasing up to $25 million of ACIC stock (no buybacks to date). • Where the Company determines prudent, we may issue further shares to raise capital in lieu of debt issuance. Dividends • When our capital position is in excess of our projected needs, particularly, when we experience lower catastrophe losses than what management considers to be a typical year, a special dividend may be declared for shareholders. • As a catastrophe exposed underwriter, we believe this approach provides the Company with a stronger capital position than a regular quarterly dividend.
