Founded in 1945 in Bentonville, Arkansas, Walmart (WMT) is the world’s largest retailer and operates on a truly staggering scale. For example, its 2.2 million employees serve 275 million consumers per week in 27 nations via a network of more than 11,000 stores that collectively sell over $500 billion of merchandise per year. Approximately 50% of Walmart’s stores are located in international markets, which the company entered in 1991. These locations serve about 100 million customers per week under 56 different banners (store brands). While Latin America, the UK, and Canada are important regions, the majority of Walmart’s sales and profits are derived from the company’s U.S. stores (64% of revenue) and Sam’s Club (12%).
