Revenue Model & Pricing
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.

Growth Strategy
Growth is mostly organic: appointing more independent agencies, expanding into new states, and adding specialty products. Recent emphasis includes high net worth personal lines, E&S casualty and property through CSU, Cincinnati Re, and Cincinnati Global at Lloyd's. Management prices policy by policy using its own data and modeling, aiming for steady premium growth with combined ratios in the low-to-mid 90s rather than market share at any price.
