Buffett's Berkshire Sees Major Leadership Shake-Up
10 Dec
Summary
- Berkshire Hathaway announced significant leadership changes, including an unexpected departure.
- Finance chief Marc Hamburg will transition responsibilities over two years.
- Leadership shifts signal preparations for Warren Buffett's upcoming retirement.

Berkshire Hathaway has initiated a significant management restructuring, marking one of the most substantial leadership changes in decades. The shake-up includes a surprising executive exit, the planned retirement of finance chief Marc Hamburg, and the creation of a new general counsel role. These transitions are strategically timed as Warren Buffett prepares to hand over the CEO reins to Greg Abel on January 1.
Finance head Marc Hamburg will transition his duties to Charles Chang, head of Berkshire Hathaway Energy's finance, by June 2026, with his retirement set for June 2027. Observers note that Hamburg's extended transition period highlights his dedication to Berkshire's stability. His contributions to deal structuring and financial management have been deemed critically important, though perhaps historically underappreciated.
