Jana is working on the investment with holding company Continental Grain and has identified several industry executives, including Lamb Weston's former executive chairman Timothy McLevish, as potential board candidates. Wall Street analysts have said Cargill, Post, Tyson Foods and Kraft Heinz could be hypothetical buyers. Jana has a history with Lamb Weston and in 2015 pushed Conagra, which owned the business at the time, to divest it. Lamb Weston became a publicly listed company in 2016. Now the activist is pushing Lamb Weston to make changes or possibly face a board challenge. Jana has extensive experience in the food sector, pushing for improvements most recently at pet food manufacturer Freshpet, and in earlier campaigns at companies including Whole Foods, Pinnacle Foods, Safeway and Conagra.
