ARCH CAPITAL GROUP LTD.

Arch Capital Group Ltd. (NASDAQ: ACGL) operates as a global provider of insurance, reinsurance, and mortgage insurance products through its wholly owned subsidiaries. The company maintains its website at www.archgroup.com and serves clients worldwide with a focus on specialty lines of insurance and reinsurance where underwriting expertise creates meaningful competitive advantages.

The company operates through three primary underwriting segments: insurance, reinsurance, and mortgage operations. The insurance segment conducts operations across Bermuda, the United States, the United Kingdom, Europe, Canada, and Australia, offering specialty lines on both admitted and non-admitted bases through multiple subsidiaries including Arch Insurance Company, Arch Specialty Insurance Company, and Arch Indemnity Insurance Company. The reinsurance segment operates globally through Arch Reinsurance Ltd. in Bermuda, Arch Reinsurance Company in the United States, Arch Reinsurance Europe in Ireland, and Lloyd's of London syndicates, writing both proportional and non-proportional business on a treaty and facultative basis. The mortgage operations segment provides direct mortgage insurance in the United States through Arch Mortgage Insurance Company and United Guaranty Residential Insurance Company, international mortgage insurance through European and Australian platforms, and participates in government-sponsored enterprise credit risk-sharing transactions.

For 2025, the company wrote $16.5 billion in net premiums and reported net income available to common shareholders of $4.4 billion, with approximately $26.9 billion in capital at year-end 2025. The company maintains a diversified geographic footprint with underwriting platforms across multiple continents and operates through experienced management teams specializing in talent-intensive rather than labor-intensive business lines. Arch Capital has pursued strategic acquisitions including the August 2024 acquisition of Allianz's U.S. Middle Market Property and Casualty Insurance and Entertainment businesses, which enhanced its capabilities in the U.S. middle market. The company also holds significant investments in affiliated entities including a 30 percent stake in Greysbridge Holdings Ltd., 25 percent of Premia Holdings Ltd., and 29.5 percent of Coface SA, a France-based trade credit insurance leader.
