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.

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

Kraft Heinz Co. is preparing to break itself up, people familiar with the matter said. Under the plan, the company could spin off a large part of its grocery business into a new entity, according to the people. This would allow it to focus on faster-growing segments such as sauces, they said.
