Berkshire Hathaway Reports Nearly 30% Drop in Q4 Operating Earnings as Buffett Concludes CEO Tenure

Operating Earnings Decline Marks End of an Era

Berkshire Hathaway Inc. announced a substantial decline in its operating earnings for the fourth quarter of 2025, reporting a nearly 30% drop. This period notably marks Warren Buffett's final quarter as the conglomerate's Chief Executive Officer, a role he held for decades before handing the reins to Greg Abel at the start of 2026. Despite the decrease in operating profit, Buffett will continue to serve as chairman.

The company's operating profit fell to $10.2 billion in the fourth quarter of 2025, down from $14.53 billion in the same period a year earlier. This reduction was largely attributed to challenges within its insurance operations and a significant impairment charge related to an investment.

Insurance Sector Faces Headwinds

A primary factor contributing to the overall earnings decline was a substantial reduction in income from Berkshire Hathaway's insurance businesses. Insurance underwriting profits saw a sharp decrease, plummeting by 54% to $1.56 billion. Concurrently, insurance investment income also fell by nearly 25%, settling at $3.1 billion. These figures underscore the pressures experienced by the company's core insurance segments during the quarter.

Occidental Petroleum Writedown Impacts Results

Further impacting the quarterly results was a $4.5 billion impairment charge. This writedown was associated with Berkshire Hathaway's long-standing investment in Occidental Petroleum. The company indicated that this charge reflected its assessment that the recent decline in the oil company's stock price was not 'temporary.' Despite this significant writedown, Berkshire Hathaway stated its intention to retain its shares in Occidental Petroleum.

Leadership Transition and Financial Position

The fourth quarter of 2025 concluded Warren Buffett's tenure as CEO, a position he held for 60 years. Greg Abel officially assumed the role of CEO at the beginning of 2026, with Buffett remaining as chairman. Berkshire Hathaway ended 2025 with a substantial cash reserve of $373.3 billion. While net income for the quarter saw a modest 3% decrease to $19.2 billion from $19.69 billion, Buffett has consistently advised investors to prioritize operating earnings as a more accurate measure of the company's performance, given the volatility of GAAP net income influenced by investment gains and losses.
