Delphi Solar

What Delphi Solar does

Delphi Financial Group, Inc. is a financial holding company focused on specialty insurance and insurance-related services in North America. Founded in 1987 by Robert Rosenkranz, the company built its franchise through a series of strategic acquisitions: Reliance Standard Life Insurance Company (1987, employee benefits and group life/disability), Safety National Casualty Corporation (1996, excess workers' compensation and risk solutions), Matrix Absence Management (1998, absence management services), and Custom Disability Solutions (2006, reinsurance support services). The company was publicly listed on NASDAQ in 1990, transferred to NYSE in 1996, and merged into Tokio Marine Group in May 2012, becoming a wholly-owned subsidiary of Japan's largest non-life insurer.

Delphi operates a decentralized model in which subsidiaries (Reliance Standard, Safety National, Matrix Absence Management, Custom Disability Solutions, Tokio Marine Delphi Capital Management) maintain their own brands and operating autonomy while benefiting from centralized investment management and parent-level financial resources. Revenue is generated primarily through insurance premiums (life, disability, group term life, excess workers' compensation) on a recurring subscription-like basis, supplemented by service fees from absence management and reinsurance arrangements. Distribution combines independent brokers and agents for mid-market employer benefits, direct enterprise sales to self-insured employers for workers' compensation, and specialized sales to large commercial and public entity clients.

The company's competitive position is anchored by 75+ years of Safety National's specialized workers' compensation expertise, A++ A.M. Best financial strength at the Tokio Marine parent level, and approximately $200 billion in parent assets supporting underwriting capacity and acquisitions. AM Best affirmed Delphi's credit ratings in 2025 with a positive outlook revision for Standard Security Life Insurance Company of New York, and S&P assigned an A+ rating to a new Safety National reinsurance subsidiary in the same year. Most recently, Delphi agreed in November 2025 to acquire a majority stake in ACORE Capital, expanding into U.S. commercial real estate investment management.
