Kinsale Capital Group Business Summary

Kinsale Capital Group, Inc. (KNSL) is a specialty insurance holding company that generates revenue primarily through net earned premiums and investment income, operating exclusively within the U.S. Excess and Surplus (E&S) lines market. The company focuses on hard-to-place risks for small-to-mid-sized accounts, with its business concentrated in Casualty (70.7% of gross written premiums) and Property (29.3%) lines, while maintaining a single reportable segment. Kinsale distinguishes itself through a proprietary technology platform that enables a best-in-class expense ratio of approximately 20.8% and a disciplined underwriting approach, resulting in a 2025 combined ratio of 75.9%. Its primary competitors include Markel Group, W.R. Berkley, RLI Corp., and James River Group Holdings; within this landscape, Kinsale occupies a high-margin niche as a technology-driven, low-cost operator that consistently outpaces industry growth rates through superior risk selection and operational efficiency. The company was founded in 2009 by Michael P. Kehoe, who serves as Chairman and CEO and brings extensive E&S experience from his former role as CEO of James River Insurance Company. The current executive leadership team includes President and COO Brian D. Haney (scheduled to retire March 2, 2026), EVP and CFO Bryan Petrucelli, EVP and Chief Underwriting Officer Stuart P. Winston, and EVP and Chief Information Officer Diane Schnupp, who manages the firm’s critical proprietary technology infrastructure.
