Berkshire Hathaway Warren Buffett (10% Owner) Gifts Class A Shares

What Happened

• Warren E. Buffett (reported as a 10% owner) converted derivative securities into 37,500 shares of Berkshire Hathaway Class A common stock on May 18, 2026 and then gifted two blocks of shares—18,646 and 18,646 shares—to charitable organizations. The conversion and gifts are reported at $0.00 per share. The filing also reports a separate 25-share derivative conversion marked as disposed (derivative).

Key Details

• Transaction date: May 18, 2026; Form 4 filed May 20, 2026 (appears timely).
• Conversions/acquisitions: 37,500 shares via conversion of derivative security (reported $0.00).
• Gifts/dispositions: two gifts of 18,646 shares each (reported $0.00); footnote confirms gifts to charitable organizations.
• Additional item: conversion/disposition of 25 shares reported as a derivative transaction (N/A price).
• Shares owned after transaction: reported in Table II of the Form 4 (see full filing for post-transaction holdings).
• Footnotes: F1 confirms gifts were to a charitable organization; F2 notes Class A shares are convertible into 1,500 Class B shares and holdings of Class A are reported in Table II.

Context

• These transactions are charitable gifts and a derivative conversion, not open-market buys or sales — gifts do not necessarily signal Buffett’s view of Berkshire stock price. Conversion of a derivative means a right or instrument was converted into Class A shares (no cash paid). As a 10% owner and long-time chairman, Buffett’s gifts are administrative/charitable moves rather than routine insider buys or sales.
