Starboard put corporate America on notice with its campaign in 2013 against Darden Restaurants, the owner of Olive Garden and Longhorn Steakhouse, among other dining chains. With less than a 10% stake Smith replaced the entire 12-person board and assumed the role of chairman. By the time Smith stepped down in 2016, Darden stock had gained nearly 50% and Starboard had accrued more than $500 million in profits.
