Warren Buffett stepped down as chief executive officer of Berkshire Hathaway on January 1, 2026, ending a legendary 60-year tenure that transformed the conglomerate into one of the world’s most powerful investment engines. Greg Abel, who joined Berkshire in 1992 and served as vice chairman of non-insurance operations, took over the CEO role while Buffett remained as chairman.
Buffett’s six-decade run delivered staggering returns for shareholders. From 1964 to 2024, Berkshire achieved compounded annual gains of 19.9%, nearly double the S&P 500’s 10.4%, resulting in an overall return of more than 5.5 million percent, according to CNBC. When Buffett took control of what was then a struggling textile company, shares traded around $19; by the end of 2025, a single Class A share was worth over $750,000.
The transition marked one of several major CEO changes in 2026, a year that saw leadership shifts across technology, retail, and industrial sectors. Buffett’s departure was particularly significant because his tenure spanned nearly the entire modern era of professional investing, and his annual shareholder letters and presence at Berkshire’s “Woodstock for Capitalists” annual meeting shaped how investors thought about markets, capital allocation, and long-term value creation.
Abel faces the challenge of managing a $1.03 trillion conglomerate with dozens of operating businesses, including Geico insurance, the BNSF railroad, Berkshire Hathaway Energy, and Dairy Queen. The company held $373 billion in cash at the end of 2025, underscoring both its financial firepower and Buffett’s caution in what he viewed as a richly valued market. Berkshire has been a net seller of equities for 12 consecutive quarters, according to Reuters, reflecting limited investment opportunities at its massive scale.
Abel, 63, has over 30 years of Berkshire experience and served as president and CEO of MidAmerican Energy before his elevation to vice chairman in 2018. At the 2026 annual shareholder meeting in May, he emphasized continuity with Buffett’s investment philosophy and culture of patient, long-term thinking. However, investors have focused attention on how Abel will manage Berkshire’s approximately $300 billion equity portfolio, which includes major stakes in Apple, Coca-Cola, and American Express. When Todd Combs, who had overseen much of the stock portfolio, departed for JPMorgan Chase in December 2025, Abel inherited responsibility for 94% of the holdings.
Buffett signaled he would “go quiet” as he stepped back from the public role he held for six decades. He will no longer write Berkshire’s annual shareholder letters, a tradition he began in 1965 that became essential reading on Wall Street for its plainspoken wisdom on markets, management, and capital allocation. Instead, Abel assumed responsibility for the letters starting in 2026. Buffett will continue to pen a Thanksgiving message to shareholders, but his reduced public presence marked a symbolic end to an era that defined how many investors approached their craft.
Berkshire shares underperformed the S&P 500 significantly in the months following Buffett’s announced departure in May 2025. By April 2026, Berkshire was down 12% from the announcement, while the broader index had risen 25%, according to Reuters. Some investors attributed the gap partly to uncertainty about the transition and the company’s limited options for deploying its massive cash hoard in a market that Buffett had deemed overvalued.
