AI brief of an SEC Form 8-K · Berkshire Hathaway (BRK-B)

Berkshire Hathaway names Charles C. Chang CFO, succeeding Marc Hamburg on June 1, 2026

Neutral Impact 4 of 5 leadership Written later

Berkshire Hathaway said Charles C. Chang will succeed Marc D. Hamburg as chief financial officer on June 1, 2026, with an annual cash salary of $8 million. The filing also covers a May 2, 2026 annual meeting, where shareholders approved executive pay and rejected a shareholder proposal on workforce oversight, and a May 3, 2026 bylaw update; the 8-K itself does not report first-quarter earnings figures.

Key points

  • Charles C. Chang succeeds Marc D. Hamburg as CFO on June 1, 2026, at an annual cash salary of $8 million.
  • Berkshire estimates the cost of Hamburg's NetJets flight benefit at about $490,000 per year, for up to 30 flight hours a year through May 31, 2037.
  • Advisory say-on-pay vote: 403,351 for and 30,251 against at the May 2, 2026 annual meeting.
  • Shareholder proposal on workforce and human-capital oversight: 65,023 for and 367,387 against, so it did not pass.
