Summary
Summary of the 8-K filed November 3, 2025. Cited figures are marked; the original filing is the authoritative source.
Berkshire Hathaway's third-quarter 2025 earnings release, issued November 1, 2025, shows net earnings attributable to Berkshire shareholders of $30.8 billiona, up from $26.3 billion a year earlier.
However, this headline figure is heavily inflated by investment gains, which were $17.3 billionb in the quarter, driven largely by changes in unrealized gains on equity holdings and $8.2 billion of after-tax realized gains. Management explicitly cautions that quarterly investment gains or losses are usually meaningless and can be misleading on a per-share basis, so investors should focus on operating results. Operating earnings, which exclude investment gains and losses, rose to $13.5 billion in Q3 2025 from $10.1 billion in Q3 2024, a 34% increase.
The improvement was led by insurance underwriting, which swung to $2.4 billionc from $750 million, and by manufacturing, service and retailing, BNSF, and a $1.4 billion contribution from Other, which included a foreign currency gain on non-U.S. dollar debt of roughly $331 million. Insurance investment income declined modestly to $3.2 billion, and Berkshire Hathaway Energy's earnings fell to $1.5 billion from $1.6 billion. For the first nine months of 2025, net earnings were $47.8 billion versus $69.3 billion in 2024, a decline reflecting much smaller investment gains and a $3.8 billion after-tax other-than-temporary impairment on Kraft Heinz.
Operating earnings for the nine-month period were $34.3 billiond, up from $32.9 billion. Insurance float reached approximately $176 billion at September 30, 2025, up $5 billion since year-end 2024. The release itself warns that it is not adequate for an informed investment decision and directs readers to the 10-Q for full detail.

03—Questions
Frequently Asked Questions
Why did Berkshire's net earnings rise in Q3 2025 while nine-month earnings fell?
Q3 2025 net earnings benefited from $17.3 billion of investment gains, largely from changes in unrealized gains on equity holdings plus $8.2 billion of after-tax realized gains. Nine-month net earnings fell from $69.3 billion to $47.8 billion because 2024 included much larger investment gains, including $76.5 billion of realized gains, and 2025 included a $3.8 billion Kraft Heinz impairment.
What is the difference between net earnings and operating earnings for Berkshire?
Net earnings include investment gains and losses, which are volatile and largely driven by stock market movements in equity holdings. Operating earnings exclude these items and reflect the performance of Berkshire's businesses, including insurance, railroad, utilities and energy, and manufacturing, service and retailing. Management considers operating earnings a more meaningful measure of ongoing performance.
What drove the strong improvement in insurance underwriting?
Insurance underwriting earnings rose to $2.4 billion in Q3 2025 from $750 million in Q3 2024, a sharp improvement. The release does not provide detailed causes in this summary, so investors should consult the 10-Q for information on underwriting results, catastrophe losses, and loss ratios.
Why did Berkshire Hathaway Energy and insurance investment income decline?
Berkshire Hathaway Energy operating earnings fell to $1.5 billion in Q3 2025 from $1.6 billion, and insurance investment income dropped to $3.2 billion from $3.7 billion. The release does not explain these declines in detail, so the 10-Q is the appropriate source for underlying reasons, such as interest rate changes or segment-specific factors.
Is this earnings release sufficient for making an investment decision?
No. Berkshire explicitly states that the press release is not adequate for making an informed investment judgment and urges investors to read the 10-Q, which provides fuller financial statements, segment detail, and risk disclosures.
