What it means: The company formally changed governance rules that govern officer roles, appointments, authorities, or related procedures. The filing does not disclose the specific text of the amendments within the provided content, so the exact operational or control effects are not stated.

Why it matters: Changes to officer- and agent-related by‑laws can alter delegation of authority, signing rights, succession mechanics, or administrative procedures. These are governance-level adjustments that may affect internal controls and decision workflows; however, the filing excerpt provides no detail on substantive rights or limitations, so material financial or strategic impact is not demonstrated in the disclosure.

ITEM 5.03 Amendments to Articles of Incorporation or Bylaws; Changes in Fiscal Year

(a) On September 30, 2025, the Board of Directors (the “Board”) of Berkshire Hathaway Inc., a Delaware corporation (the “Company”) voted to amend and restate the Company’s By-Laws effective immediately. The primary purpose of the amendment was to separate the role of the Chairman of the Board of Directors and the role of the Chief Executive Officer of the Company. As previously reported on a Form 8-K dated May 3, 2025, on May 4, 2025, the Board voted unanimously to appoint Mr. Greg Abel to become the Company’s President and Chief Executive Officer effective January 1, 2026. Mr. Abel will replace Mr. Warren Buffett, Berkshire’s current Chief Executive Officer on that date. Mr. Buffett will continue to be Chairman of the Company’s Board of Directors.

As a result of the upcoming change whereby the Company’s Chairman of the Board of Directors and the Company’s Chief Executive Officer will no longer be positions held by the same person, a new Paragraph 3.5 was added to Section 3 – Board of Directors of the Company’s By-Laws and various changes were made to Section 4 – Officers and Agents of the Company’s By-Laws.

The foregoing description of the amendment and restatement of the By-Laws does not purport to be complete and is qualified in its entirety by reference to the full text of the By-Laws attached hereto as Exhibit 3(ii) and incorporated by reference.
