Lancashire Holdings Ltd. is a specialty insurance and reinsurance company that underwrites complex, niche, and difficult-to-price risks often avoided by broader commercial insurers. The company operates through two primary segments: Reinsurance and Insurance. The Reinsurance segment, which accounted for approximately 53% of gross premiums written in 2025, provides casualty, property, and specialty reinsurance, including catastrophe-exposed and excess-of-loss treaty portfolios. The Insurance segment, generating the remaining 47% of premiums, offers direct coverage across property, energy, marine, and aviation classes. Lancashire operates globally with key underwriting platforms in Bermuda, London (including its Lloyd's of London Syndicate 2010), and Australia. The company's business model relies on disciplined underwriting, active cycle management, and capital efficiency, generating revenue through premium collection and investment returns on its portfolio.
