Warren Buffett's Berkshire Hathaway saw a significant increase in operating profit for Q3 2025, rising 34% year over year to $13.485 billion. This boost was largely due to a remarkable 200% jump in insurance underwriting income, which hit $2.37 billion. Despite the company's stock price decline, Buffett opted against buybacks, maintaining the cash reserve at a record $381.6 billion, up from $347.7 billion earlier in the year. Class A and B shares have both increased by 5% in 2025, although they lag behind the S&P 500's 16.3% rise. Berkshire's net selling of equities in the third quarter resulted in a taxable gain of $10.4 billion, indicating a lack of attractive investment opportunities. Buffett, who announced plans to step down as CEO by year-end, will pass leadership to Greg Abel, the current vice chairman of noninsurance operations. This transition has led to a notable drop in Berkshire's stock, reflecting what some are calling the "Buffett premium"—the extra valuation investors assign due to Buffett's renowned investment acumen. In a notable strategic move, Berkshire agreed to purchase Occidental Petroleum's petrochemical unit, OxyChem, for $9.7 billion in cash, marking its largest acquisition since 2022. Overall earnings, which factor in gains from investments in publicly traded companies, increased by 17% to $30.8 billion compared to the previous year.
