Shares in Kraft Heinz (KHC) were under pressure premarket after the food giant announced Buffett would be retiring from its board of directors.
"Mr. Buffett decided to retire from the board as he decreases his travel commitments," Kraft Heinz said in a press release on Friday.
Shares in Buffett's investment firm, Berkshire Hathaway (BRKA), were rising after the company published his annual letter to investors on Saturday.
Buffett told investors that Berkshire Hathaway made a $65.3 billion net gain in 2017, but roughly $29 billion of that came from changes to the US tax code.
"A large portion of our gain did not come from anything we accomplished at Berkshire," he wrote.
