While investors originally cheered the merger, the luster began to fade as the combined company's U.S. sales faltered. Then came a disclosure in February 2019 that Kraft Heinz had received a subpoena from the Securities and Exchange Commission related to its accounting policies and internal controls. The company also slashed its dividend by 36% and took a $15.4 billion write-down on Kraft and Oscar Mayer, two of its biggest brands. Days later, Buffett told CNBC that Berkshire Hathaway had overpaid for Kraft. A leadership shakeup and more write-downs of iconic brands, like Maxwell House and Velveeta, followed. Kraft Heinz also began divesting some of its businesses, selling off most of its cheese unit to French dairy giant Lactalis and its nuts division, including the Planters brand, to Hormel. In recent quarters, the company has invested in boosting some of its brands, like Lunchables and Capri Sun. Despite turnaround efforts, shares of Kraft Heinz have slid roughly 60% since the merger closed in 2015.
