Berkshire Hathaway Inc. (NYSE: BRK.A) remains a different kind of large-cap equity story: less about rapid top-line growth and more about underwriting discipline, operating durability, liquidity, and long-term capital allocation. Berkshire reported full-year 2025 net earnings attributable to shareholders of $67.0 billion, down from $89.0 billion in 2024, but its own annual report again emphasized that operating earnings are the better measure of underlying business performance. On that basis, Berkshire delivered $44.5 billion of operating earnings in 2025, compared with $47.4 billion in 2024.

What Drives Berkshire’s Business?

Berkshire is best understood as a capital allocation platform built on a large insurance base. The company itself describes insurance as its core business, with substantial investments and operating subsidiaries across railroads, energy, manufacturing, services, and retail. That structure matters because Berkshire’s earnings power is not dependent on a single operating segment; instead, it comes from a mix of underwriting profits, float, wholly owned operating businesses, and investment income.

How Strong Was Berkshire’s Operating Performance?

Why Does Berkshire Emphasize Operating Earnings Over Net Income?

Because GAAP net income can be heavily distorted by unrealized gains and losses in the equity portfolio. Berkshire explicitly says these swings are often “meaningless” for understanding periodic business performance. In 2025, after-tax investment gains and losses still had a major impact on reported results, which is why management directs investors toward operating earnings as the cleaner measure.

What Were the Most Important Operating Strengths in 2025?

Cash generation remained a major strength. Berkshire produced $46 billion of net cash flows from operating activities in 2025, above its five-year average of more than $40 billion. Shareholders’ equity reached $717.4 billion at year-end, up $68.1 billion from the prior year. These numbers underline one of Berkshire’s core advantages: it can remain patient and opportunistic because its balance sheet is unusually strong.

How Important Is Insurance to Berkshire?

Insurance remains the most important operating foundation. Berkshire said its property and casualty businesses produced a combined ratio of 87.1% in 2025, better than its five-year average of 90.7%, ten-year average of 93.0%, and twenty-year average of 92.2%. In insurance, lower is better; that makes 2025 an excellent underwriting year by Berkshire’s own historical standards. The report also highlighted GEICO’s continued improvement in cost structure and underwriting discipline, though it cautioned that restoring retention while maintaining pricing discipline will take time.

Why Did Berkshire Stock Remain Supported Recently?

Berkshire’s recent support has come less from excitement and more from confidence in quality. Investors continue to value the company’s balance-sheet strength, insurance underwriting discipline, and ability to earn more on cash and T-bills when liquidity is high. Berkshire also noted that increased investments in U.S. Treasury Bills were a major reason corporate investment income rose in 2025. In more uncertain macro environments, that kind of optionality tends to support the stock’s defensive appeal.

What Are Analysts Focused on in Berkshire?

Analyst Insights

The main investor questions around Berkshire are relatively consistent: can insurance underwriting stay this strong, can large subsidiaries improve productivity, and how effectively will Berkshire deploy capital when opportunities arise? The annual report was candid that some operating businesses still have room for improvement, including BNSF, where operating margin improved to 34.5% in 2025 from 32.0% in 2024 but still lagged the best operators in the industry. That candor is important because Berkshire’s story is often about incremental operational improvement plus exceptional capital allocation rather than rapid growth.

What Is the Bull Case for Berkshire?

The bull case is built on resilience. Berkshire has insurance float, diversified operating businesses, large investment income, and enormous liquidity. It generated $46 billion in operating cash flow in 2025, maintained very strong underwriting results, and ended the year with substantially higher shareholders’ equity. For investors seeking quality and downside resilience rather than aggressive growth, those are powerful characteristics.

What Is the Bear Case for Berkshire?

The bear case is mostly about relative growth and capital deployment. Berkshire is so large that it is harder to move the needle with new investments, and reported earnings can look less impressive when investment gains are lower or when operating earnings soften versus a prior strong year. The company also recorded goodwill impairment losses in 2025 tied to certain building products, consumer products, and retailing businesses, underscoring that not every operating segment is firing equally well.

How Sustainable Is Berkshire’s Performance?

Berkshire’s performance is sustainable in a different way than growth tech. It is sustained by underwriting discipline, diversified operating cash flows, and balance-sheet strength rather than by rapid revenue growth. That makes it less explosive but often more durable across cycles. The core question for long-term holders is whether Berkshire can continue allocating capital at attractive rates as scale increases and leadership transitions continue.
