12 Stock Price, Scenarios & Sensitivity

  • BRK.B closed at $573.50 on 10 Nov 2026, 2.1% below the 52 week high of $586.00 and 23.5% above the low of $464.36; market value $1.22tn on 2.12bn Class B equivalent shares.
  • Scenario basis: price to book value per Class B share. Book value per Class B share is derived for this report as Berkshire shareholders' equity of $761.4bn divided by 2.13bn Class B equivalent shares (Class A shares times 1,500): $357.73 at 30 Sep 2026, against $332.55 at 31 Dec 2025 (+7.6%). Price to book 1.60x now; 1.37x to 1.51x at the year ends FY2022 to FY2025 and 1.39x at 30 Sep 2026.
  • Other measures: 25.8x TTM operating earnings of $47.2bn and 15.8x TTM net earnings, which include $34.3bn of investment gains. Implied price = book value per Class B share in three years times the exit price to book multiple.

Repurchases$9.6bn in Q3 2026; $14.4bn in 9Mcontinued repurchases below intrinsic valueForm 10-Q Part II Item 2; $30bn cash floor
Short term ratesinsurance investment income pretax $3.32bn in Q3, (10.7%)stable short term ratesForm 10-Q MD&A
  • Base: book value per Class B share $357.73 at 30 Sep 2026 (derived). TTM operating earnings equal 6.2% of equity; the equity portfolio equals 44.1% of equity, so a 10% move in its value changes book value by about 3.5% after a 21% deferred tax rate.
  • Best case: book value per Class B share +10% a year, exit price to book 1.7x, above the 1.60x of 10 Nov 2026; operating earnings growth and equity gains above the base.
  • Base case: +8% a year, below the 10.1% annualized rate of 9M 2026 and the 15.4% CAGR of FY2022 to FY2025; exit 1.5x, the level of FY2024 and FY2025 year ends.
  • Worst case: +3% a year, with equity portfolio losses offsetting part of retained operating earnings; exit 1.3x, below the FY2022 to Q3 2026 range of 1.37x to 1.51x.
  • No dividend; repurchases at prices above book value reduce book value per share slightly and are inside the growth assumptions. Implied annual return is the price change only.
