Discount grocer Aldi said Wednesday it's acquiring 400 Winn-Dixie and Harveys supermarkets in the Southern U.S. Under a proposed merger agreement, Aldi will acquire all outstanding shares of Jacksonville, Florida-based Southeastern Grocers Inc., the parent company of Winn-Dixie and Harveys. If the deal is approved by regulators, it's expected to close in the first half of 2024. Financial terms of the deal weren’t disclosed. Both Southeastern Grocers and Aldi are private companies. Aldi is based in Germany with its U.S. headquarters in Batavia, Illinois. Aldi said it will convert some locations to its own brand and format but will operate some stores under the Winn-Dixie and Harveys brands.
