MERCURY GENERAL CORP (MCY) stock intrinsic value fair value estimate & owner earnings analysis

Mercury General is a California-centred personal lines insurer. Private passenger auto insurance is about 60% of its premiums, and about 85% of its auto premiums are written in California. The rest comes from homeowners, commercial auto, commercial property and umbrella coverage, written in California and ten other states and sold mostly through independent agents (about 88% of direct premiums in 2025). Mercury also runs a small software-development subsidiary in Shanghai that serves its own systems. Its insurance business is entirely in the United States. How we measure earnings. We start from operating cash flow. We strip out the timing swings from growing loss reserves and unearned premiums, and we leave out investment gains and losses, which netted only about $167 million over 2014 to 2025. Share-based pay and the fixed-asset spending needed to stay in business are charged. On that basis, owner earnings per share were $2.51 (2014), $2.91, $2.21, $1.90, $2.15, $2.99, $5.97, $3.39, -$1.31 (2022), $0.68, $6.99 and $7.99 (2025). The swings come from a cycle that is built into the business. California requires approval before auto and home rates change (Proposition 103), so rates lag behind claim inflation and then catch up. Margins troughed in 2017-18 and 2022-23 and peaked in 2020 and 2024-25. Normal earning power. The business has roughly doubled in premium since 2014, mostly through rate increases that passed claim inflation on to customers. We therefore measure the normal level as the median owner-earnings margin on earned premium across the full 2014-2025 cycle. That margin is 4.77%. Applied to 2025 earned premium of $5.51 billion, it gives about $4.63 a share after a roughly $0.10 a share higher interest bill. That higher bill comes from June 2026, when Mercury refinanced its 4.40% notes due 2027 with $525 million of 6.25% notes due 2036. Owner earnings rose 14% in 2025. Our first-year figure of $5.06 is up 9% on the normal level, reflecting premiums already written (earned premium was up 11% in the first half of 2026). We deliberately do not count today's above-average margins (a 2026 first-half combined ratio of 89.6%) as permanent. Base case ($90.91 a share). Earnings run at the cycle-average margin. Premiums grow 2% a year in years 2-10, well below the 6.3% a year earned-premium growth of 2014-2025. Each $2.50 of new premium is charged $1 of capital retained to support it. After year 10, earnings hold flat. That continuation rests on a franchise that has written California auto insurance through its agent network for more than six decades, not on assumed further growth. Bear case ($47.93 a share). Two average years are followed by a repeat of a major Los Angeles-area wildfire without a utility to recover from, costing about $8 a share net of reinsurance. The 2025 Palisades and Eaton fires produced $531 million of catastrophe losses even after $586 million of recoveries, and in the second quarter of 2026 those fires needed about $80 million more in reserves. A rate-lag loss year like 2022 follows. Margins then settle permanently at 3.4%, the lower quarter of the historical range, with no growth. The case also assumes the $538 million booked recovery from Southern California Edison for the Eaton fire (55% of losses) settles at 45% instead, costing about $1.40 a share. Bull case ($109.76 a share). The 2024-25 margin of about 7.8% holds for three years on premiums already in force, and a milder trough at a 4% margin lasts two years. Margins then run at 5.5% with 2% premium growth to year 10, holding flat afterwards. The case adds about $4 a share for statutory surplus ($2.77 billion at June 30, 2026) above what a conventional 2.5-to-1 premium-to-surplus ratio requires. Debt. For an insurer, borrowing and interest are part of running the business, so we value earnings after interest and do not subtract debt again. After the July 2026 redemption of the 2027 notes, holding-company debt is about $575 million: $525 million of 6.25% notes due 2036 and $50 million drawn on a bank facility due November 2027. That is modest against $2.77 billion of statutory surplus, and every case, including the bear case's two loss years, can carry it. Since our previous analysis. Our previous estimates were $24 (bear), $66.60 (base) and $123.70 (bull). The bear and base cases rise mainly because we now discount every case at a fixed 6% and express risk through the cases themselves rather than through a higher discount rate. They also rise because normal earnings are now scaled to today's much larger premium base. The bull case falls because it no longer assumes peak earnings keep compounding indefinitely. What would make this wrong. More frequent large California wildfires, or reinsurance costs that rate approvals do not recover. A longer or deeper rate-lag cycle than 2022-23. Weak recovery on the Eaton fire claim. On the other side, Mercury's recent combined ratios near 90% could last longer than the history suggests.
