Berkshire Hathaway Inc. announced a handful of leadership changes including the retirement of its longtime chief financial officer, as the $1 trillion conglomerate prepares for the retirement of Warren Buffett. Marc Hamburg will end his 40-year tenure at the firm in 2027 and hand over his role as chief financial officer next year to Charles Chang, according to a statement Monday. Separately, Nancy Pierce will become CEO of Geico, filling a spot held by Todd Combs, a Berkshire investment manager who is leaving to take a job at JPMorgan Chase & Co.
