Insights

Insurance and reinsurance analyst

ACIC secures 2026 catastrophe reinsurance, stabilizing potential loss volatility.

American Coastal Insurance Corporation has locked in two major catastrophe reinsurance layers for the 2026 contract year. The renewed all other perils catastrophe excess of loss agreement gives up to $95.6M of occurrence limit above a $10.0M attachment, with a $10.0M per‑occurrence retention net of quota share, at a cost of about $11.4M. This structure is designed to cap losses from non‑wind, non‑earthquake catastrophe events.

The catastrophe aggregate excess of loss cover adds a $40M aggregate limit, with a $20M per‑occurrence cap, after a $40M annual aggregate deductible is reached, for the full year ending December 31, 2026. Priced at about $4.9M, this contract addresses the combined impact of multiple events, including named windstorms and severe convective storms. Overall, these renewals outline the company’s 2026 catastrophe risk transfer framework, though actual financial impact will depend on catastrophe activity during the period.
