Supervalu is also seeking shareholder support for restructuring itself into a holding company, a move that may ease some logistics as it seeks to sell more of its retail operations in the future. The company since 2016 has been focused on beefing up its wholesale business, which distributes groceries in most regions of the U.S., while scaling back in retail. After the sale of its Save-A-Lot chain for more than $1 billion a year ago, Cub Foods is now the largest of the retail chains still in its portfolio.
