Berkshire Hathaway
, with new CEO Greg Abel in charge, has taken a formal step toward unwinding a rare misstep by Warren Buffett.
The conglomerate, which owns GEICO insurance and BNSF Railway, registered its entire 27.5% stake in Kraft Heinz
in a filing that clears the way for Berkshire to exit its position in the hot dog and mac-and-cheese maker. Berkshire is Kraft Heinz’s largest shareholder.
Shares of Kraft Heinz fell 5% in premarket trading following the news.
