Cincinnati Financial is the parent of The Cincinnati Insurance Company and its sister carriers. It writes business-owner, commercial auto, workers' compensation, property and liability coverage for small and mid-sized businesses, homeowner and auto coverage for individuals including high net worth clients, and hard-to-place E&S risks through Cincinnati Specialty Underwriters. Cincinnati Re writes reinsurance, Cincinnati Global operates Syndicate 318 at Lloyd's, and The Cincinnati Life Insurance Company sells life products. Everything moves through independent agents, not direct online sales or captive agents. The massive American property and casualty insurer was founded in Fairfield, Ohio in 1950, aggressively building an absolute fortress of financial stability by exclusively utilizing highly loyal, independent local insurance agents.
Cincinnati Financial makes money in two ways. First, its insurance subsidiaries collect premiums for commercial, personal, excess and surplus (E&S), reinsurance and Lloyd's policies and aim to pay less in claims and expenses than they collect; a combined ratio under 100% means an underwriting profit, and the 2025 ratio was 94.9%. Second, it invests the premiums it holds before claims are paid. Unlike most insurers, it keeps a large share of that portfolio in common stocks, so investment income rose 14% in 2025 while swings in equity values flow straight into net income. Policies are sold only through independent agencies, and field underwriters and claims staff live in the territories they serve.
