Based on reports through December 31, 2025
The issuer has several share classes — market cap covers the whole company.
American Financial Group insures unusual commercial risks through many independently run units.
Each unit works in its own narrow market: crop insurance, transport liability, directors' liability, marine cover. Price here is set by expertise rather than a rate table, and that is precisely why specialty insurance is more profitable than the mass market.
The company is known for discipline: it cuts volume when rates fall below what is sensible and adds when they rise — growth is not an end in itself. Management has stayed in the family across generations. Risks: litigation trends, reserve adequacy and weather in crop insurance. Investment income on reserves adds to that, and at high rates it lifts the result noticeably. A dividend is paid, including regular special distributions.
