Berkshire Hathaway closed 2025 with a familiar paradox: hefty cash, concentrated equity stakes and durable operating cash flows alongside weaker underwriting results and a sizable investment writedown. The company reported net income attributable to shareholders of $66.97 billion for the year, down from $89.00 billion in 2024, while full-year operating earnings — the metric management stresses as most meaningful — fell to $44.5 billion from $47.4 billion the year before.
Greg Abel, the new chief executive, authored his first annual shareholder letter as Berkshire’s leader and used it to emphasize continuity in culture and capital allocation even as Warren Buffett formally stepped down as CEO at age 95. Abel made a point of saying that Buffett remains chairman and works “five days a week,” framing the management handover as orderly and reassuring investors that the company’s decentralized management model and long-standing values remain intact.
Underwriting weakness was the principal drag on operating profits in 2025. Insurance underwriting profit fell to $7.26 billion from $9.02 billion a year earlier, and fourth-quarter underwriting profit plunged by more than half versus the prior year. Insurance investment returns also softened, leaving the insurance complex under pressure even as Berkshire’s non-insurance businesses, including BNSF and Berkshire Hathaway Energy, continued to generate steady cash flows.
Abel pointed to recurring volatility in realized and unrealized investment gains and reiterated Berkshire’s preference for judging annual performance by operating earnings and cash generation. Berkshire produced $46.0 billion of net cash from operations in 2025, above the company’s five-year average, and finished the year with a cash reserve of about $373.3 billion. That cash pile gives Berkshire the optionality to pursue large acquisitions or opportunistic share purchases, but Abel stressed a “planned and prudent” capital-allocation stance.
The letter also disclosed a combined $4.5 billion impairment tied to Kraft Heinz and Occidental Petroleum, and flagged disappointment with Kraft Heinz in particular. Meanwhile, roughly two-thirds of Berkshire’s $297.8 billion equity portfolio is concentrated in five names — Apple, American Express, Bank of America, Coca-Cola and Chevron — a concentration Abel said is deliberate and likely to persist unless long-term fundamentals change materially.
On the subject of international exposure, Abel confirmed that Berkshire’s borrowings in Japan roughly match its yen investments, with the cost of those borrowings around 1.2% and an average maturity near 5.75 years. He noted that core U.S. and Japanese holdings, valued at about $194.0 billion, produced roughly $2.5 billion of dividends in 2025 on an original cost base of $24.5 billion, underscoring the long-term yield these positions have generated for shareholders.
The practical takeaway is twofold: Berkshire remains a financially robust conglomerate with ample dry powder, and its culture of decentralized management and capital discipline survives the leadership transition. But the near-term mix is less sanguine — insurance multiples and investment returns can swing widely year to year, and recent writedowns plus weaker underwriting highlight the limits of immunity from cyclical pressures.
Investors will watch how Abel deploys Berkshire’s unprecedented cash balance. Large acquisitions would test both Berkshire’s price discipline and Abel’s instincts as capital allocator; conversely, continued patience preserves optionality but risks criticism that idle cash is an opportunity cost. The upcoming shareholder meeting in Omaha on May 2, where Abel will share the stage with other senior managers, will be an early venue for gauging how shareholders react to his stewardship and to the firm’s strategic priorities.
