How Does Cincinnati Financial Make Money?
No single line supplies a majority of revenue: the largest, Commercial Lines Insurance, is 39%, which spreads Cincinnati Financial's exposure across several demand drivers. Between fiscal 2024 and 2025, Personal Lines Insurance grew fastest (+21.9%) and Life Insurance slowest (+3.1%), so the revenue mix tilts toward Personal Lines Insurance while that gap lasts.
| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Commercial Lines Insurance | $4.9 billion | $4.5 billion | 38.5% | 8.4% |
| Personal Lines Insurance | $3.2 billion | $2.6 billion | 25.4% | 21.9% |
| Investment Segment of CINF | $2.6 billion | $2.4 billion | 20.6% | 7.9% |
| Excess and Surplus Lines Insurance | $702 million | $618 million | 5.6% | 13.6% |
| Life Insurance | $336 million | $326 million | 2.7% | 3.1% |
What the Segment Figures Do Not Show
The rows above add up to 93% of Cincinnati Financial's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.
Where These Numbers Come From
Every figure on this page is a value Cincinnati Financial reported in the segment note and revenue disclosures of its Form 10-K filed February 23, 2026 (accession 0000020286-26-000008), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.
Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
