Metro AG is a German multinational company based in Düsseldorf which operates business membership-only cash and carry stores primarily under the Metro brand. As of March 2024, Metro is operating 626 wholesale stores in 21 countries. The company was established in 1964 by Ernst Schmidt and Wilhelm Schmidt-Ruthenbeck. In 2010, it was the fourth-largest retailer in the world measured by revenues, after Walmart, Carrefour and Tesco. Until 2020, it was also active in the general retail business through the Real division, which was sold to an investor consortium. Its current incarnation was launched in 2017 as a spun-off of old Metro AG, which continued to be a consumer electronics retailer and renamed itself Ceconomy. Wikipedia
