Warren Buffett Steps Down as Berkshire Chairman: What the Transition Means for Shareholders

Warren Buffett announced on Friday, September 18, 2026, in a letter to shareholders that he is stepping down as Chairman of Berkshire Hathaway. The 96-year-old investor is relinquishing the position effective immediately, ending an era that began in 1970. His son Howard Buffett is taking over the chairmanship, while Greg Abel, who has served as CEO since January 2026, continues to lead the company operationally.

Succession planning implemented over months

The transition follows a long-term succession plan. In May 2025, Buffett surprised thousands of shareholders at the annual meeting by announcing his intention to step down from the CEO position. In January 2026, Greg Abel finally took over the CEO post, while Buffett initially remained as Chairman. Now comes the relinquishment of this last operational function as well.

In his letter, Buffett wrote: "Father Time always wins. He has, however, been generous with me. He has given me the opportunity to see Berkshire reach a point where I am more confident than ever about what lies ahead." Buffett will serve as Chairman Emeritus going forward and remains a board member.

Howard Buffett as guardian of culture, Greg Abel leading operations

Howard Buffett, who has served on Berkshire Hathaway's board since 1993, is meant to serve as the "guardian" of the culture and values built over the decades, according to his father's words. Warren Buffett described the division of roles this way: "Think of Howard as a policy the shareholders own and hope never to claim against." Responsibility for strategic and operational decisions lies with CEO Greg Abel.

Buffett spoke approvingly of Abel's performance: Abel has exceeded "sky high" expectations and makes important decisions without Buffett needing to think twice. Abel himself confirmed the division of duties: "Greg runs the company; Howard will guard its culture and values." Abel previously held the position of Vice-Chair and has already initiated share buybacks and other capital allocations.

From textile mill to trillion-dollar conglomerate

When Buffett took over Berkshire Hathaway in 1965 at the age of 34, it was a deteriorating textile mill in New England. Today, the company employs nearly 400,000 employees and has a valuation of approximately 1.1 trillion U.S. dollars. Operating earnings in 2025 amounted to 44.5 billion U.S. dollars.

Berkshire today owns companies such as the insurance company GEICO, the fast-food chain Dairy Queen, and the railroad system BNSF. The conglomerate also holds significant stakes in Apple and Coca-Cola. Under Buffett's leadership, shareholders achieved an average annual return of 19.7 percent—nearly double the S&P 500's performance over the same period.

Cash reserves and stock performance in 2026

In the second quarter of 2026, Berkshire held cash reserves of 365.5 billion U.S. dollars, a decline from the record-high 397 billion U.S. dollars in the prior quarter. In July 2026, Buffett announced that he would completely divest his personal stake of approximately 140 billion U.S. dollars by 2034.

Berkshire Hathaway's stock performance has been subdued so far in 2026. The stock has risen just 1.3 percent since the start of the year, while the S&P 500 rose 11.6 percent over the same period. On Thursday, September 20, 2026, the Class B stock closed at 509.20 U.S. dollars and was little changed on Friday morning.

Textbook governance from investors' perspective

Christopher Davis of Hudson Value Partners commented on the move: "While the share price performance has been frustrating this year despite positive trends in the underlying business, the announcement that Warren Buffett will shift to chairman emeritus is the latest example in the textbook of good governance at Berkshire."

Buffett, known as the "Oracle of Omaha," shaped generations of investors with his value-investing philosophy. His strategy focuses on companies with solid fundamentals that are bought at fair prices and held for decades. His annual shareholder letters and festival-like annual meetings made him a leading mentor in the financial world.

Despite stepping down from the CEO position, Buffett remained active as Chairman until the end. He came to the Omaha office daily to search for new investments and advise Abel. The annual meeting in May 2026, the "Woodstock for Capitalists," was led by someone other than Buffett for the first time—he did, however, attend and give an interview with CNBC reporter Becky Quick. Susan Decker continues to serve as Lead Independent Director on the board.
