The document indicates that Berkshire Hathaway may reduce its shares in Kraft Heinz by 27.5%.

According to a regulatory document, Berkshire Hathaway may reduce its 27.5% stake in Kraft Heinz and exit this investment made over a decade ago, as it has not been successful for the conglomerate's chairman Warren Buffett. Kraft Heinz's products include Heinz ketchup and Oscar Mayer meats. The company submitted a supplemental prospectus filing to the SEC on Tuesday, aiming to register Berkshire's potential resale of its 325.4 million shares. Berkshire is the largest shareholder of Kraft Heinz to date. In 2015, Berkshire helped Kraft Heinz merge with Brazilian private equity firm 3G Capital. The company divested its Kraft Heinz stake in 2023. The merger of the former Kraft Foods and H.J. Heinz companies proved to be disappointing, as the combined company announced in September that it would split in two later this year. Buffett told the media at the time that he and Greg Abel, then vice chairman of Berkshire and now CEO, did not support the split. Kraft Heinz's stock closed up 23 cents on Tuesday at $23.76, valuing Berkshire's stake at about $7.7 billion. In after-hours trading following the filing of the supplemental prospectus, Kraft Heinz's stock fell by 4.9% to $22.59.
