May 18 (Reuters) - Campbell Soup Co Chief Executive Officer Denise Morrison unexpectedly stepped down on Friday, at the same time the company said it would embark on a review of its vast array of brands and issued a bleak forecast for the year.
Campbell's stock fell 11 percent in morning trading, hitting a more than five-year low and putting it on track for its worst one-day decline since 1999.
Shares of B&G Foods, General Mills and Kraft Heinz also slipped after Campbell said it anticipates higher import tariffs and freight costs to weigh on profit margins until its fiscal year 2019 ends in August next year.
Morrison, 64, departs the company after seven years at the helm. Campbell provided no reason for her departure, but said board member Keith McLoughlin, 61, would replace her in the interim immediately.
The company also said it would conduct a thorough, critical review of all its business plans and portfolio composition over several months to improve its financial performance.
"Everything is on the table. There are no sacred cows," McLoughlin said on a conference call with analysts.
Packaged food companies like Campbell have been pressured as consumers increasingly move away from processed food toward healthier options. These shifting consumer tastes are partly to blame for four straight years of declines at Campbell's U.S. soup business, a period during which Morrison was in command.
Other parts of the business such as juices and its Campbell Fresh division have also struggled, resulting in a two-year decline in organic sales.
"This news comes as a surprise. Morrison has faced some missteps as CEO (declining soup sales and Campbell-Fresh execution issues) and the sudden departure likely reflects ongoing execution issues," Edward Jones analyst Brittany Weissman said.
JPMorgan analyst Ken Goldman said he expects the Campbell Fresh unit, which sells baby carrots and high-end juices, to be a top-priority candidate for review. The unit had sales of $251 million in the third quarter ended April 29.
On Friday, Campbell Soup posted a loss of $393 million or $1.31 per share for the third quarter, compared with a profit a year ago, mainly due to a $619 million charge related to Campbell Fresh.
Excluding one-time items, the company earned 70 cents per share, 10 cents above analysts' average estimate, according to Thomson Reuters I/B/E/S. Net sales rose 15 percent to $2.13 billion.
Campbell said the acquisition of snacks maker Snyder's-Lance, a deal it closed just eight weeks ago, would reduce adjusted earnings in fiscal year 2019.
The company expects earnings per share to fall between 5 percent and 6 percent, compared with its earlier forecast for a rise of 2 percent to 4 percent. The prior forecast did not include the impact from Snyder's-Lance. (Reporting by Nivedita Balu and Siddharth Cavale in Bengaluru; Editing by Maju Samuel, Bernard Orr)
