Material Event (Form 8-K)

Berkshire Hathaway Inc.'s long-standing common stock repurchase policy permits us to repurchase shares of our Class A and Class B Common Stock at any time we believe the repurchase price is below our intrinsic value, conservatively determined. In the interest of transparency with our leadership transition, we are disclosing that we commenced repurchasing shares of our common stock under this policy on Wednesday, March 4, 2026.

Our repurchase policy does not obligate us to acquire any specific number of shares. Shares may be repurchased in open-market repurchases or in privately negotiated transactions, including pursuant to trading plans that may be adopted in accordance with Rule 10b5-1of the Securities Exchange Act of 1934, as amended. The timing and total amount of stock repurchases will depend on the market prices of our Class A and Class B common shares, market conditions, and other relevant factors. Repurchases may be suspended or discontinued at any time without prior notice. Berkshire does not undertake any obligation to update or revise any disclosures regarding our repurchases, including any suspension or termination of the repurchases, except as may be required by applicable law or regulation (including through the disclosure of repurchase activity in Berkshire's periodic reports on Form 10-Qand Form 10-K).
