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

Kraft Heinz is looking to spin off a large chunk of its grocery business, including many Kraft products, into a new entity that could be valued at as much as $20 billion on its own, the Wall Street Journal reported on Friday.

A decade after the megamerger of Kraft and Heinz, the packaged food powerhouse is preparing to break up amid shifting consumer tastes and mounting financial pressure.
