Markel Group Inc (NYSE: MKL) is a financial holding company that operates specialty insurance, reinsurance, and diversified industrial and services businesses. It earns money through insurance premiums written across its underwriting segment, investment income from a float-driven portfolio, and operating earnings from its Markel Ventures portfolio of owned businesses. The company is headquartered in Richmond, Virginia and was founded in 1930. Its insurance operations focus on hard-to-place, specialty, and surplus lines risks, where standard carriers typically do not compete. The Markel Ventures segment owns controlling interests in a range of non-insurance businesses spanning manufacturing, construction services, and consumer products. Per the 10-K filed 2026-02-26 for fiscal year ended December 31, 2025, Markel operates across three reported segments: Insurance, Reinsurance, and Markel Ventures. Investment income and net investment gains from the float-backed portfolio represent a material portion of total revenues alongside earned premiums.
