AMERICAN COASTAL INSURANCE Corp

There have been no material changes to the risk factors previously disclosed in Part I. Item 1A "Risk Factors" of the Company's Annual Report on Form 10-K for the year ended December 31, 2024, except as set forth below.

Because we rely on insurance agents, the loss of these agent relationships, particularly our relationship with AmRisc, LLC (AmRisc), or our inability to attract and incentivize new agents could have an adverse impact on our business.

AmCoastal has a managing agency contract (the MGA contract) with AmRisc, pursuant to which AmRisc serves as AmCoastal’s managing general agent for binding and writing commercial residential property lines for condominium, townhome and homeowners association insurance written in Florida. The contract between AmCoastal and AmRisc is exclusive. Under the MGA contract with AmCoastal, AmRisc must produce a certain volume of business for AmCoastal. Therefore, failure of AmRisc to produce the required volume of business could cause us to lose substantial premiums and could require us to seek one or more alternative managing general agents. If we were unable to find a replacement managing general agent, our revenues could decrease, which could have a material adverse effect on our business, financial condition and results of operations. Given the concentration of AmCoastal’s commercial business and operations with AmRisc, AmRisc may have substantial leverage in negotiations with AmCoastal regarding the MGA contract, and amendments to the terms and conditions of the MGA contract or other changes to the commercial relationship between AmRisc and AmCoastal could have a material adverse effect on our business, financial condition and results of operations. Following the termination or expiration of the MGA contract, AmCoastal’s ability to compete for and solicit renewals of business previously underwritten by AmRisc may be limited by legal, commercial and other impediments, including AmRisc’s relationship with other insurance producers that control the business. Such impediments could have a material adverse effect on our financial condition and results of operations due to the concentration of AmCoastal’s business with AmRisc.

As of September 30, 2025, we market our apartment insurance product through a network of 10 independent wholesalers. These wholesalers and their brokers own the customer relationships and are not under our direct control. Our contracts restrict us from directly soliciting their policyholders, and most brokers also represent competing insurers. As a result, we must continually compete for their attention and business. Competitors may offer broader product options, lower premiums, or higher broker commissions. Consequently, our success depends heavily on the strength of our broker relationships and our ability to offer competitive, well-aligned insurance solutions. Losing any of these wholesale relationships—or failing to attract, retain, or motivate new brokers—could negatively impact new business production and retention of in-force policies.
