Otis joined Darden in 1995, ascended to the CEO spot in late 2004 and became chairman a year later. His departure isn't entirely a surprise, given Darden's troubles. The company has been pressured to turn around declining sales at Olive Garden and Red Lobster. Customers had begun turning away from those chains as they cut back on spending during the recession.
Darden Restaurants Inc. earlier on Monday announced that it had completed the sale of Red Lobster to investment firm Golden Gate Capital. Activist investors Barington Capital and Starboard Value had objected to the nature of the breakup.
Barington had also said in March that it was time for Darden to start looking for a new chief executive, citing the company's "rapidly deteriorating financial performance." Last week, Starboard said it was suing Darden for documents related to Red Lobster's sale.
The company also said it expects to nominate nine of its independent directors for its board, meaning that at least three Starboard nominees would be elected. But Darden said it failed to reach an agreement with Starboard over the investment firm's pending proxy contest after settlement discussions.
A new CEO and an independent chairman were "positive steps," but three Starboard board seats were not enough, said Barington CEO James Mitarotonda in an emailed statement. "Significant change is required in the Darden boardroom that can only be accomplished through the election to the board of a new slate of independent directors," he said.
Starboard has nominated 12 directors for Darden's board. The investment firm did not immediately return messages Monday.
Otis will serve as CEO until a successor is named or Dec. 31, whichever comes first. The company said it will start looking for a replacement for him.
