Walmart Inc

Walmart operates a global network of discount retail stores and membership warehouse clubs. In the U.S., it runs roughly 4,600 Walmart stores selling groceries (about 60% of U.S. revenue), general merchandise, and pharmacy products to everyday consumers at low prices. Sam's Club (~600 locations) is a members-only warehouse format that charges annual membership fees on top of merchandise sales. Internationally, operations are concentrated in Mexico, with additional presence in India and other markets. Revenue comes almost entirely from product sales, with smaller contributions from membership fees and advertising. Customers are primarily everyday shoppers seeking low prices on groceries and household goods.
