When Warren Buffett speaks, Wall Street listens. And when one of his portfolio companies makes a headline-grabbing move, investors can’t help but take notice. That’s precisely what happened last week when Kraft Heinz (KHC) shocked the market with a bold plan to split into two separate companies.
The move didn’t just surprise investors—it also drew a rare public expression of dissatisfaction from none other than Buffett himself. The legendary investor, whose Berkshire Hathaway (BRK.A) (BRK.B) owns more than a 27% stake in Kraft Heinz and remains its largest shareholder, admitted he was “disappointed” with management’s decision to pursue the breakup, arguing that it will be costly, disruptive, and ultimately not the right course for shareholders. However, while Buffett’s critique pushed KHC stock down about 7% in a single session, the announcement has reignited a broader conversation about whether Kraft Heinz could be at an inflection point.
