Warren Buffett's bet on Kraft Heinz is looking like an acquisition stumble with an unclear path forward.

Buffett's Berkshire Hathaway on Saturday turned in a $25.4 billion loss in the fourth quarter, weighed down in part by a $3 billion write-down, largely connected to its investment in the food giant. Last year, Kraft, one of Berkshire's largest holdings, pulled the conglomerate's results down with a $2.7 billion loss, compared with the $2.9 billion in earnings it added in 2017.
