Wal-Mart Stores is an irresistible (or at least unavoidable) retail force that has yet to meet any immovable objects. The world's largest company by revenue and bigger than Europe's Carrefour, Metro AG, and Tesco combined, Walmart is the world's #1 retailer with more than 2.3 million employees. In the US, Wal-Mart operates more than 5,300 stores, including about 4,570 Wal-Mart stores and 655 Sam's Club warehouses, and a growing number of smaller format stores. The company's faster growing international division (26% of sales) numbers more than 6,100 locations; Wal-Mart is the #1 retailer in Canada and Mexico and has operations in Asia (where it owns a 95% stake in Japanese retailer SEIYU), Africa, Europe, and Latin America.
