Kraft Heinz is preparing to break itself up, a decade after an infamous merger of two of the biggest names in packaged foods that was orchestrated by Warren Buffett and Brazilian private-equity firm 3G Capital Partners.

Kraft Heinz weighs grocery spin-off valued at up to $20 billion, aiming to refocus on growth categories like condiments amid shifting consumer tastes, WSJ reports.

A decade since they tied the knot, the Kraft Heinz union may be headed for splitsville. The packaged food conglomerate, which has been underperforming for years, is mulling a spinoff of a large portion of its grocery business.
