Berkshire Hathaway

shares slipped Friday as investors digested the formal end of Warren Buffett’s six-decade tenure as chief executive and the start of a new era under successor Greg Abel.

Class A shares fell as much as 1.4% in morning trading on Abel’s first day as CEO, following Buffett’s official handoff of the role and the close of one of the most storied leadership tenures in corporate history. The stock last traded 0.5% lower.

The Omaha-based conglomerate ended 2025 with a gain of 10.9%, trailing the S&P 500′s 16.4% advance but marking its 10th consecutive year of positive returns. Buffett, 95, remains chairman and has sought to reassure shareholders that Berkshire’s future extends well beyond his tenure.
