On September 18, 2026, Reuters reported that Warren Buffett stepped down as chairman of Berkshire Hathaway Inc. (NYSE:BRK-B), becoming chairman emeritus effective immediately. His son Howard Buffett is taking over as non-executive chairman. The move comes nearly nine months after Buffett stepped down as CEO in favor of longtime lieutenant Greg Abel, and Buffett, aged 96, will remain a director on the board.

Bull Case
Berkshire Hathaway Inc. (NYSE:BRK-B) planned this transition years in advance. It reduces the likelihood of operational disruption. The company identified Abel as Buffett’s successor in 2021, while Howard Buffett has served on Berkshire’s board since 1993. Abel has also held senior leadership positions at Berkshire since 2018. This long preparation gives both leaders extensive knowledge of Berkshire’s decentralized operating structure and unusually long-term corporate culture.
The new governance structure assigns clear responsibilities rather than concentrating every role in one person. Abel controls operations and capital allocation, Howard protects Berkshire’s culture as non-executive chairman, and Susan Decker provides independent board leadership. Buffett also remains a director and can offer limited judgment and perspective without interfering with Abel’s authority. This arrangement preserves institutional knowledge while establishing clear accountability under the new CEO.
Berkshire enters the post-Buffett era from a position of considerable financial strength. Reuters reported that second-quarter operating profit increased 16% to $12.98 billion and that the company held $364.7 billion in cash and equivalents. Berkshire’s shares also compounded at 19.7% annually from 1965 through 2025, compared with 10.5% for the S&P 500. Its diversified businesses and enormous liquidity give Abel substantial flexibility for acquisitions, investments, and repurchases.

Bear Case
Berkshire Hathaway Inc. (NYSE:BRK-B)’s final departure from the chairmanship could speed up the erosion of Berkshire’s valuation premium. LSEG data cited by Reuters show that Berkshire’s price-to-book ratio declined from approximately 1.62 to 1.53 after Buffett first announced his CEO departure. Investors historically paid a premium for Buffett’s capital-allocation record and ability to reassure shareholders during crises. The market may assign a lower multiple until Abel shows comparable results independently.
Berkshire’s recent stock performance raises questions about whether its immense size now limits future returns. Reuters reported that Berkshire had gained only around 1% in 2026, compared with approximately 12% for the S&P 500, and had trailed the index slightly on an annualized basis over the preceding decade. Berkshire now requires very large investments to move its overall results, which makes reproducing Buffett’s historical outperformance increasingly difficult.
The transition also places more responsibility on Abel while removing Buffett as a regular adviser. Reuters reported that Buffett will not retain a management position or routinely serve as Abel’s sounding board. Howard provides cultural continuity, but he has never managed a public company and will hold a non-executive role. Therefore, Abel must prove that he can place Berkshire’s cash balance effectively and maintain discipline across a sprawling collection of businesses.
Hedge Fund Sentiment
Berkshire Hathaway Inc. (NYSE:BRK-B)’s Class B shares saw hedge fund interest grow to 135 holders in the second quarter from 126 in the first, with position value rising to $22.73 billion from $21.63 billion, according to Insider Monkey’s database. Markel Group, a smaller insurance-led conglomerate often compared to Berkshire’s model, saw holders decline slightly to 51 from 53, with position value edging up to $2.04 billion from $1.88 billion.
Conclusion
The leadership change does not create an immediate operating crisis because Berkshire prepared for it well in advance and has a strong balance sheet, experienced managers, and clear governance roles. However, Buffett’s departure removes the unique capital allocator and symbolic anchor that supported Berkshire’s valuation for decades.
The stock’s long-term direction will now depend less on preserving Buffett’s image and more on Abel’s execution, particularly how he places Berkshire’s $364.7 billion cash reserve and whether he can improve performance relative to the S&P 500. The transition looks operationally manageable but financially consequential: Berkshire remains a high-quality company, although investors should demand evidence before assuming that its historical “Buffett premium” will survive unchanged.
