The outlook of the Long-Term ICR has been revised to stable from positive while the outlook of the FSR is stable.

These Credit Ratings (ratings) reflect Kinsale’s balance sheet strength, which AM Best assesses as very strong, as well as its strong operating performance, favorable business profile and appropriate enterprise risk management (ERM).

The Long-Term ICR upgrade reflects the strengthening of Kinsale’s business profile, supported by its increased scale, established position in the U.S. excess and surplus lines market and demonstrated ability to grow while maintaining disciplined underwriting and strong profitability. Kinsale is a property/casualty insurance company founded in June of 2009, operating exclusively in the U.S. excess and surplus lines market and has grown to approximately $2.0 billion of gross written premiums as of year-end 2025. The company benefits from an experienced management team, specialized underwriting expertise and proprietary technology. Kinsale distributes its surplus lines policies primarily through a network of independent wholesale brokers throughout the United States.

The ratings are also supported by the company’s risk-adjusted capitalization at the strongest level, as measured by Best’s Capital Adequacy Ratio (BCAR), as well as continued organic surplus growth driven by consistent profitable underwriting performance and reliable net investment income. Kinsale has a strong focus on underwriting fundamentals.
