“I will become Chairman Emeritus and remain a Director.”

Warren Buffett, Berkshire chairman, signed shareholder letter 18 September 2026 Berkshire news release Sep 18, 2026 (Howard Buffett elected Chairman) (Berkshire Hathaway)

Warren Buffett becomes Chairman Emeritus of Berkshire and remains a director.

Delivered on time The record shows it happened or was so.

The evidence is the person's or their organisation's own records.

Said for an organisation they lead or work for; it counts on both records.

What would count as true or false

The claim has two parts: Buffett takes the title Chairman Emeritus of Berkshire Hathaway, and he stays on the board as a director, both by 2026-09-18. True: an official Berkshire announcement, 8-K or proxy filing shows that by 2026-09-18 Buffett holds the title Chairman Emeritus and is still a sitting director. Mostly true: both hold, but the effective date or exact wording of the title differs slightly in a way the claim does not depend on (for example 'Chairman Emeritus of the Board'). Mostly false: only one part holds (for example he remains a director but receives no emeritus title, or gets the title but leaves the board), or both happen only after 2026-09-18. False: filings or announcements dated on or after 2026-09-18 show that he neither has the emeritus title nor remains a director, or that he kept the role of chairman or left Berkshire's board entirely.

Evidence

  1. Berkshire Hathaway Inc. News Release Business Wire · 18 September 2026 Own record
    “Berkshire Hathaway Inc. today announced that Warren E. Buffett has been named Chairman Emeritus, effective immediately, in recognition of his extraordinary contributions to Berkshire and its owners. As Chairman Emeritus, Mr. Buffett will remain a member of the Board of Directors and will continue to offer his valued judgment and perspective.”
  2. Berkshire Hathaway Inc. News Release Business Wire · 18 September 2026 Own record
    “Consistent with the company's long-standing succession plan, the Board has elected Howard G. Buffett, a Berkshire director since 1993, as Chairman of the Board.”

Reasoning

Berkshire Hathaway's official news release dated 2026-09-18 [E1] says Warren E. Buffett has been named Chairman Emeritus, effective immediately, and will remain a member of the Board of Directors. The same release [E3] says the Board elected Howard G. Buffett as Chairman of the Board, which confirms that Warren Buffett did not keep the chairman role. Both parts of the claim are shown to hold by the deadline in an official company announcement, which the criteria accept as sufficient.
