Berkshire Hathaway has unveiled a series of major leadership appointments across its non-insurance, insurance, and corporate divisions, marking a significant evolution in its senior ranks. It also announced the leaving of long-time investment manager and GEICO head Todd Combs.
Non-Insurance Operations
Adam M. Johnson, longtime CEO of NetJets, has been named President of Berkshire’s Consumer Products, Service and Retailing group. Johnson will continue leading NetJets while supporting the CEOs of 32 businesses in the consumer portfolio. Gregory E. Abel, Vice Chairman for Non-Insurance Operations, praised Johnson’s record of delivering long-term value and strengthening global operations. Abel will continue overseeing the remaining non-insurance units—including BNSF, Berkshire Hathaway Energy, Pilot, McLane, and industrial and building products—as he prepares to assume the role of Berkshire’s President and CEO in 2026.
Insurance Operations
Nancy L. Pierce has been appointed CEO of GEICO. A GEICO veteran since 1986, Pierce rises from her role as COO, bringing decades of experience across claims, underwriting, product management, and regional leadership. Ajit Jain, Vice Chairman for Insurance Operations, emphasized her practical and results-driven leadership.
The move coincides with the departure of Todd A. Combs, GEICO’s CEO since 2020, who is leaving Berkshire to take a senior role at JPMorgan Chase. Warren E. Buffett credited Combs with expanding GEICO’s capabilities and making strong leadership hires.
Corporate Leadership
Marc D. Hamburg, Berkshire’s long-serving CFO, will retire in 2027 after four decades with the company. Buffett called Hamburg’s contributions “indispensable” and praised his integrity and judgment. Charles C. Chang, currently CFO of Berkshire Hathaway Energy, will succeed Hamburg in June 2026, with a yearlong transition underway.
Berkshire is also creating a new corporate role: Senior Vice President and General Counsel. Michael J. O’Sullivan will step into the position on January 1, 2026. O’Sullivan joins from Snap Inc. and previously spent over twenty years at Munger, Tolles & Olson advising on governance, litigation, and major transactions.
Together, these appointments underscore Berkshire Hathaway’s longstanding focus on selecting leaders who embody its culture, demonstrate strong judgment, and preserve the company’s distinctive decentralized approach.
