Costco Adds 7 New Stores in August, Targets 30+ Openings per Year

For brick‑and‑mortar retailers, Costco’s announcement of seven August openings is the clearest signal yet that the warehouse club juggernaut is betting big on physical expansion when most peers are shrinking footprints. Each new warehouse doesn’t just generate product sales—it captures thousands of high‑loyalty member households who pay annual fees, delivering a recurring revenue stream that insulates Costco from e‑commerce headwinds. As the company pushes toward its long‑term goal of 30‑plus net new stores every year, rivals from Kroger to Target must contend with a retailer that leverages 82.9 million members and buying power that reshapes local markets.

Costco is set to open seven new warehouse locations in August 2026, marking another step in an aggressive global expansion strategy that saw recent openings in Syracuse, Utah, and Pensacola, Florida in June, and a new Taiwan store this month. The retailer continues to press its advantage as one of the few big‑box chains still growing its physical footprint at scale, with 928 warehouses worldwide and 82.9 million paid members. The August openings, while location details remain limited, underscore a deliberate counter‑cyclical bet on brick‑and‑mortar at a time when many retailers are contracting. The company’s real‑estate pipeline is robust: on the May 28 earnings call, President and CEO Ron Vachris announced a revised 2026 target of 26 net new stores, while maintaining a long‑term aspiration of 30‑plus net openings per year. This cadence would add roughly 3% to the store base annually, compounding Costco’s already formidable scale advantages in buying power, supply chain efficiency, and membership economics.

The membership‑fee structure—$65 for Gold Star, $130 for Executive—provides a reliable, high‑margin revenue stream.

The expansion arrives as competitors like Walmart’s Sam’s Club also grow but at a much slower rate. Costco’s model thrives on high volume, low margins, and membership fees that contribute the lion’s share of operating profit. Each new warehouse not only adds immediate top‑line revenue through product sales but, more importantly, injects thousands of new member households into its recurring‑fee ecosystem. With membership renewal rates consistently above 90% in the U.S. and Canada, these new stores become annuity‑like assets that strengthen Costco’s moat against e‑commerce giants and discount rivals alike. The ability to self‑fund real‑estate expansion from cash flow—without relying on debt—gives Costco a strategic flexibility few retailers enjoy.

The Buffalo, New York area exemplifies the pent‑up demand Costco can unlock. There, the nearest warehouse is 75 miles away in Rochester; the new Amherst location, slated for the last week of October, will be the region’s first. Business First reports that local officials have confirmed the opening timeline and that Costco is actively hiring. Such underserved markets represent high‑return greenfield opportunities, as initial member sign‑ups and shopping frequency tend to spike upon entry, creating immediate positive unit economics. Similarly, the Taiwan opening this month extends Costco’s successful international playbook, where it has thrived in markets such as Canada, Mexico, Japan, and Korea.

Financially, the expansion supports the thesis that Costco can continue to deliver low‑double‑digit earnings growth without relying on price increases. The membership‑fee structure—$65 for Gold Star, $130 for Executive—provides a reliable, high‑margin revenue stream. Approximately 45% of members hold the Executive card, which generates 2% annual rewards and drives higher average spend. With 82.9 million paid members and a growing base, even modest fee adjustments (historically every five to six years) provide a substantial earnings tailwind. The expansion plan, therefore, is not merely about square footage but about layering in a scalable, recurring‑revenue customer base that amplifies comparable‑sales growth through increased membership income.
