Top manager leaves Warren Buffett’s Berkshire as incoming CEO names team
December 8, 2025
Incoming Berkshire Hathaway CEO Greg Abel is assembling his team to help him lead the conglomerate Warren Buffett built starting in January after a couple of key departures. Berkshire said Monday that one of its two investment managers besides Buffett who has been leading Geico, Todd Combs, and longtime Chief Financial Officer Mac Hamburg are both leaving. Combs is taking a job helping JP Morgan decide how to invest $10 billion while Hamburg is retiring. Combs’ departure is the most significant news. But CFRA Research analyst Cathy Seifert said that now the question is whether insurance Vice Chairman Ajit Jain, investment manager Ted Weschler and all the CEOs of Berkshire’s myriad businesses will remain.
