Warren Buffett expressed disappointment over the Kraft Heinz split, a decade after orchestrating the merger. Berkshire Hathaway, the largest shareholder with a 27.5% stake, hasn't traded its shares since 2015. Buffett believes the merger wasn't successful and the split won't solve the company's problems. Kraft Heinz, now split into two companies, faced declining sales due to changing consumer habits and cost-cutting measures. The company has been trying to revitalize its brands and portfolio through investments and divestitures.
