The guessing game about who will succeed Warren Buffett as CEO of Berkshire Hathaway has largely focused on vice chairs Greg Abel and Ajit Jain.

But another Berkshire manager, Todd Combs, is a rising star. That status was evident in the move by Geico, Berkshire’s big auto insurance unit, to name him as CEO as of January 1, 2020. Geico is the No. 2 auto insurance company in the US behind only State Farm, and one of the most valuable and important units within Berkshire, which is the world’s largest conglomerate.
