Warren Buffett has publicly voiced his disappointment with Kraft Heinz, acknowledging the investment as a mistake before his retirement. In response to ongoing financial struggles, including an alarming 21% share loss in 2025 and deep debt levels, Kraft Heinz is initiating a split into two separate businesses: Global Taste Elevation Co. and North American Grocery Co. This restructuring aims to address persistent underperformance and may influence Berkshire Hathaway's decision to sell its substantial stake in the company, which constitutes 2.4% of its portfolio.
