The earnings‑per‑share elite
If the ranking were based solely on earnings per share, Markel Group would win in a landslide. The Richmond, Va., specialty insurance business reported diluted earnings per share of $169.22 in 2025 — roughly four times Allstate’s level and more than seven times Cincinnati Financial’s. Its operating margin, at about 18 percent, and net margin, at 13.1 percent, also place it firmly in the profitability elite.
