Costco Wholesale Corporation (NASDAQ: COST) is an American multinational retail corporation that operates a chain of membership-only big-box warehouse clubs. Headquartered in Issaquah, Washington, Costco is recognized as one of the largest retailers in the world, known for its bulk-sale business model, low-margin strategy, and private-label brand, Kirkland Signature.
By 2025, Costco operated 914 warehouses worldwide and employed over 341,000 people, generating $275.2 billion in annual revenue. The company ranks among the top 15 on the Fortune 500 list of U.S. corporations by total revenue and remains a dominant player in the retail and wholesale sectors.
History
Costco traces its roots to Price Club, founded in 1976 by Sol Price in San Diego, California. The first official Costco warehouse was opened on September 15, 1983 in Seattle by James Sinegal and Jeffrey Brotman. Initially targeting small business owners, Costco quickly expanded to include individual consumers seeking value on bulk-priced goods.
In 1993, Price Club merged with Costco to form PriceCostco, combining over 200 locations and generating $16 billion in annual sales. By 1997, all Price Club stores were rebranded as Costco Wholesale. The headquarters later relocated from Kirkland to Issaquah, Washington, in 1996.
Global Operations
As of 2025, Costco operates in 15 countries, including the United States, Canada, Mexico, Japan, Australia, China, France, Spain, South Korea, and the United Kingdom. North America accounts for over 85 percent of its store base.
The company’s warehouses follow a standardized layout emphasizing simplicity and efficiency. Costco also runs Costco Business Centers, focused on small business customers, and Costco Home Showrooms in select regions for furniture and appliance displays.
In 2024, Costco broke ground on its first mixed-use development in Los Angeles, combining a warehouse with 800 residential apartments, reflecting its expansion into urban multi-purpose retail.
Financial Performance
Costco’s fiscal 2025 revenue reached $275.2 billion, with net income of $8.1 billion and total assets of $77.1 billion. The company’s membership-based model remains its primary profit driver — over 65 percent of net operating income derives from annual membership fees, which rose in 2024 to $65 for standard members and $130 for executive members.
Its Kirkland Signature brand contributes nearly one-third of overall sales, generating $86 billion in 2024, surpassing the annual revenue of Procter & Gamble. Costco’s stock continues to be a core component of the NASDAQ-100 and the S&P 500 Index.
Business Model
Costco’s success relies on a low-margin, high-volume approach. The company limits markup to 14 percent for national brands and 15 percent for Kirkland Signature items. Each warehouse carries roughly 3,700 products, compared to over 140,000 in a typical supercenter.
By emphasizing bulk packaging, efficient logistics, and minimal advertising, Costco keeps overhead below 10 percent of revenue. Its lean model and focus on customer trust have built an industry-leading membership retention rate exceeding 90 percent.
Products and Services
Costco sells a wide range of products, including groceries, furniture, electronics, jewelry, and household goods. Its ancillary services include:
- Gas stations and pharmacies
- Optical and hearing aid centers
- Tire centers and photo services
- Costco Travel, a subsidiary offering vacation packages
- Costco Auto and Home Insurance via CONNECT
- Costco Concierge Service for technical support on electronics
Food courts at most warehouses serve the iconic $1.50 hot dog and drink combo, unchanged in price since 1985. Global menus adapt to local tastes — with poutine in Canada, bulgogi bakes in Korea, and seafood pizza in Japan.
Online and Digital Growth
Costco’s digital presence includes Costco.com, launched in 1998, offering both retail and B2B services. Online sales grew rapidly during the COVID-19 pandemic, supported by partnerships with Instacart and Shipt for same-day delivery.
The company’s app and website feature exclusive member pricing, digital membership cards, and access to Costco Connection — a free magazine with over 15 million subscribers, ranking among the top three magazines in U.S. circulation.
Management and Corporate Culture
Costco’s corporate culture emphasizes internal promotion, ethical sourcing, and employee welfare. Most executives, including current CEO Ron Vachris, began their careers in entry-level warehouse positions. The company maintains a 90 percent retention rate among employees after their first year.
Costco consistently ranks among the top U.S. employers for wages and benefits, offering full health insurance to over 85 percent of its workers. In 2021, it raised its minimum wage to $16 per hour, ahead of major competitors.
Sustainability and Ethics
Costco has committed to sourcing 100 percent cage-free eggs globally and enforcing animal-welfare standards for its suppliers. It has invested in renewable energy, low-emission refrigerants, and recycling programs across its warehouses. However, it has faced scrutiny for environmental impact in packaging and raw material sourcing, particularly regarding deforestation and meat supply chains.
Controversies
Over the decades, Costco has addressed several controversies involving labor relations, animal welfare, and product quality. Investigations by NGOs and government bodies have prompted internal reforms, including supplier audits and enhanced employee training.
In 2023, Costco was fined in Taiwan for selling berries contaminated with Hepatitis A and in Iceland for a diesel spill linked to its gas stations. Despite such incidents, Costco remains widely regarded as one of the most transparent and customer-centric retailers globally.
