The company’s stock has underperformed since its megamerger in 2015 and changing consumer tastes have hampered results.

Kraft Heinz’s stock jumps after a Wall Street Journal report that the packaged-food giant is planning a breakup, 10 years after its megamerger.

Kraft Heinz’s stock value is down about 70 per cent since the highs it reached in 2017, when the company was seen as a pioneer in the industry. News of the potential break-up was first reported by the Wall Street Journal.
