Risk factors and legal proceedings

The risks Accelerant Holdings names in Item 1A of its 10-K filed Mar 18, 2026: 71 risks under these headings, as written.⁶

• Risks Related to Our Business and Industry
• Risks Related to Our Risk Exchange and Our Members
• Our Risk Exchange has a limited operating history, which makes it difficult to evaluate its prospects, potential for expansion to new Members and product offerings, as well as the future prospects of our overall business. Any expansion efforts that are unsuccessful may materially adversely affect our business, results of operations, financial condition and prospects.
• The addition of any products to our portfolio that may result in a higher loss ratio may be less attractive for our Members and Risk Capital Partners, and may materially adversely affect our business, results of operations, financial condition and prospects.
• A decline in our financial strength rating may adversely affect the volume of business we can write.
• Certain Members may choose to leave our Risk Exchange after their contractual commitments have expired, which would adversely affect our results of operations and our ability to offer attractive risk opportunities to our Risk Capital Partners.
• If we are unable to continue enhancing our technology-based solutions at a pace that allows us to remain attractive to our Members, or continue to gain internal efficiencies and effective internal controls that promote the utility of the analytics we provide to Members, our operating results, relationships with our Members and growth could be adversely affected.
• The rapid development and implementation of artificial intelligence applications and technologies poses business, regulatory and safety risks to our business, results of operation, financial condition and prospects.
• If our Members do not provide the data they are contractually obligated to provide or the data provided by our Members is inaccurate or incomplete, our Risk Exchange and participating Risk Capital Partners may be unable to accurately price the risk transferred through our Risk Exchange.
• If our Members do not maintain consistency in the level of skill and expertise they demonstrate, or adhere to the underwriting guidelines of our Risk Exchange, our Members may experience higher loss ratios and our reputation and relationships with insurance carriers, reinsurers, other Members, other Risk Capital partners, and brokers could be harmed.
• We have generated net losses in the past and may incur losses in the future.
• Our current market share and profitability may decrease as a result of disintermediation within the insurance industry, including increased competition from insurance companies, technology companies, and participants in the financial services industry, as well as the shift away from traditional insurance markets.

Legal proceedings

Other than in the ordinary course of our business operations, we are not currently party to any civil or government investigation. We do not expect that the ultimate outcome of any of the currently ongoing legal proceedings, individually or collectively, would have a material adverse effect on our business, financial condition, results of operations, or prospects. However, the results of litigation and arbitration are inherently unpredictable, and the possibility exists that the ultimate resolution of matters to which we are or could become subject could result in a material adverse effect on our business, financial condition, results of operations or prospects.
