Arch Reinsurance

What Arch Reinsurance does

Arch Reinsurance Ltd. is a Bermuda-domiciled reinsurance company founded in 2001 and operating as a wholly-owned subsidiary of Arch Capital Group Ltd. (Nasdaq: ACGL). The company provides treaty and facultative property, casualty, specialty, and multi-line reinsurance to ceding insurance companies, with a portfolio of more than 14 product lines spanning Property Treaty, Property Facultative, Casualty Facultative, Aviation, Marine & Offshore Energy, Credit & Surety, Agriculture, Accident & Health, Life & Health, Liability, Malicious Acts, Capital Markets, and Customized Products, supplemented by the Alwyn Managing General Agent platform and the related Somers Re Ltd. sub-brand. Its core technology is a reinsurance underwriting platform that supports both treaty (portfolio) and facultative (individual risk) placements with substantial 'large-line' capacity.

The company distributes reinsurance directly to insurance companies and ceding entities through an enterprise field sales motion, with headquarters in Bermuda and additional operations in the United States (Arch Reinsurance Company) and a São Paulo representative office serving Brazil and Latin America. Reinsurance premiums are the primary revenue stream, structured as subscription/recurring contracts negotiated on a bilateral, deal-by-deal basis — contract terms and pricing are not publicly disclosed. Arch Reinsurance's competitive positioning rests on substantial capital capacity, an experienced underwriting team (including long-tenured leaders such as William Soares, who joined in 2006 and was promoted to CEO of the Bermuda operations in July 2026), and a flexible market for large lines on selected P&C and specialty contracts. The 2026 leadership restructuring — establishing Jerome Halgan as CEO of the newly formed Arch Global Reinsurance Group with dual CEOs for Bermuda and U.S. operations — signals organizational scaling and continued investment in global origination.
