Company Description
Costco Wholesale Corporation (Nasdaq: COST) is a membership-based warehouse retailer operating in the All Other General Merchandise Stores industry within the retail trade sector. Founded in 1983, Costco has developed a warehouse-club format in which members shop in large, high-volume locations and pay annual membership fees. According to company and third-party descriptions, Costco focuses on delivering high-quality goods and services at consistently low prices through this membership model.
Costco generates revenue primarily from the sale of merchandise in its warehouses and from membership fees. Polygon data indicates that Costco organizes its operations into three broad geographic segments: Costco US, Costco Canada, and Costco International. In that description, Costco US accounts for the majority of total revenue, with Canada and other international operations contributing meaningful portions as well. The same source notes that a substantial share of Costco’s revenue comes from grocery offerings, with additional revenue from general merchandise categories.
Global warehouse footprint and membership model
Recent company news releases show that Costco operates hundreds of warehouses across multiple countries. In its December 2025 and January 2026 sales updates, Costco reported operating 923 warehouses, including locations in the United States and Puerto Rico, Canada, Mexico, Japan, the United Kingdom, Korea, Australia, Taiwan, China, Spain, France, Sweden, Iceland, and New Zealand. Earlier 2025 releases reference slightly lower warehouse counts, reflecting ongoing expansion over time. These warehouses serve millions of members who pay annual fees to access Costco’s warehouse-club format.
The Polygon description highlights that Costco’s membership base numbers in the tens of millions globally and that renewal rates in the United States, Canada, and international markets are high. Within that description, the company is characterized as offering quality products at low prices, which supports strong member loyalty and renewal behavior. Membership fees appear in Costco’s reported revenue breakdowns in its earnings releases, where they are listed separately from net sales.
Sales performance and comparable sales metrics
Costco regularly reports monthly, quarterly, and annual sales results. In multiple 2025 and 2026 press releases, the company discloses net sales for specific retail months, for fiscal quarters, and for the full fiscal year. These releases also present comparable sales metrics, broken out by the U.S., Canada, and Other International, as well as for the total company. Costco additionally reports a separate metric for digitally-enabled or e-commerce sales, which it treats as a supplemental measure alongside net sales reported in accordance with U.S. GAAP.
In its September 2025 and December 2025 operating results announcements, Costco provides consolidated statements of income, balance sheets, and cash flow statements. These show net sales, membership fees, merchandise costs, selling, general and administrative expenses, operating income, and net income. They also outline key balance sheet items such as cash and cash equivalents, merchandise inventories, property and equipment, and various liabilities, including accounts payable, accrued member rewards, deferred membership fees, and long-term debt. These financial statements illustrate how Costco’s warehouse and membership operations translate into revenue, expenses, and cash flows.
Digitally-enabled and e-commerce activity
Costco’s news releases describe the evolution of its digital and e-commerce metrics. In an October 2025 sales release, Costco notes that it changed its ecommerce comparable sales metric to “digitally-enabled” comparable sales. This measure includes all sales delivered to members that are initiated through a digital device, whether fulfilled through a warehouse or a distribution center, and also includes Costco Travel. Across multiple monthly and quarterly updates, Costco reports growth rates for digitally-enabled or e-commerce sales alongside overall comparable sales.
The company also discloses that it operates e-commerce sites in several of the same countries where it has warehouses, including the U.S., Canada, the U.K., Mexico, Korea, Taiwan, Japan, and Australia. These sites provide an additional channel through which members can purchase merchandise or services, complementing the in-warehouse experience.
Corporate governance and executive compensation
Costco’s SEC filings and news releases provide insight into its governance and executive compensation structures. An October 2025 Form 8-K describes the fiscal 2026 executive bonus plan approved by the Compensation Committee and the Nominating and Governance Committee of the Board. Under this plan, executive officer bonuses are tied to targets relating to sales, pre-tax income, and environmental and social performance criteria, including metrics concerning human capital and environmental-related areas. The filing specifies maximum bonus amounts for executive officers and the chief executive officer, with potential payouts based on the level of achievement against these goals.
Another October 2025 Form 8-K reports that Costco’s Board of Directors declared a quarterly cash dividend on the company’s common stock. The filing details the dividend per share and the record and payment dates. These disclosures reflect Costco’s practice of returning capital to shareholders through regular dividends, as well as its approach to linking executive compensation to financial and non-financial performance measures.
In a December 2025 news release, Costco announces the nomination of Gina Raimondo for election to its Board of Directors. The release summarizes her background in public service and business and includes a statement from the Chairman of the Board about the experience she would bring to Costco’s board. This illustrates Costco’s ongoing board-level governance activity and the addition of directors with varied expertise.
Financial reporting and regulatory disclosures
Costco files periodic reports and current reports with the U.S. Securities and Exchange Commission. The September 2025 Form 8-K notes that the company issued a press release containing its operating results for the fourth quarter and full fiscal year and that an earnings release supplement was attached as an exhibit. These materials include detailed financial data, comparable sales metrics, and commentary on performance. Other 8-K filings cover topics such as executive officer changes and compensation arrangements.
Across its public statements and filings, Costco identifies itself as a Washington corporation and provides its Commission file number and employer identification number. The company’s principal executive offices are located in Issaquah, Washington, as disclosed in multiple 8-K filings. These regulatory documents form the official record of Costco’s financial condition, governance decisions, and other material events.
Business mix and merchandise focus
According to the Polygon description, Costco’s merchandise mix includes a significant grocery component and general merchandise categories. That description indicates that a majority of Costco’s revenue in a recent fiscal year came from grocery offerings, with a substantial additional share from general merchandise. This aligns with Costco’s classification in the retail trade sector and the “All Other General Merchandise Stores” industry, reflecting its role as a warehouse retailer offering a broad assortment of goods to members.
Costco’s monthly and quarterly sales releases do not break out detailed product categories, but they consistently reference total net sales and comparable sales across geographic segments and digital channels. The combination of warehouse operations, membership fees, and digitally-enabled sales defines Costco’s core business model as presented in its public disclosures and third-party descriptions.
