COSTCO WHOLESALE CORP /NEW

Operating through a membership warehouse model, Costco Wholesale Corporation generates revenue primarily from the sale of merchandise and ancillary services to its member base. The company's product assortment spans groceries, non-perishable foods, health and beauty items, appliances, electronics, apparel, furniture, and seasonal goods. Fresh food offerings include meat, produce, and prepared items from in-house bakeries and delis. Costco also derives significant revenue from ancillary operations including gasoline stations, pharmacies, optical centers, tire installation, food courts, and hearing-aid services.

The company maintains an e-commerce platform alongside its core warehouse operations and operates business centers and travel services. Membership fees constitute a separate revenue stream distinct from merchandise sales.
