Costco Asturias Store Moves Toward 2027 Opening

That matters because Costco’s model is built around high-volume retailing, low prices and member loyalty — the kind of formula that can pull spending away from traditional supermarkets, local wholesalers and smaller specialty chains. In a market still pressured by inflation scars and value-conscious shoppers, a large membership club with aggressive fuel pricing can reshape where households and small businesses buy everything from groceries to bulk supplies.

The economics are straightforward and potentially powerful. The project carries an estimated direct investment of 45 million to 50 million euros, will occupy a 54,586-square-meter parcel and include a 15,680-square-meter retail building, nearly 1,000 parking spaces and a fuel station with about 16 pumps. It is also expected to create at least 170 jobs in the first three years and 260 in the next three, with most positions permanent and nearly half full-time.

For investors, the story is not just about one store in Siero. It is about Costco extending a proven format into a region with room for modern retail infrastructure, while leveraging the kind of scale that can pressure incumbent chains and reward adjacent winners such as logistics, construction and local suppliers. The requirement to source from Asturian producers also creates a secondary opportunity for regional food and consumer-goods companies that can meet Costco’s volume and quality standards.

The project also shows how local governments are now competing for anchor tenants that can stimulate employment and private capital without relying on public spending. Asturias classified the development as strategic earlier this year, overcoming zoning constraints that would otherwise have blocked a store of this size. That kind of designation can become a template if the opening proves successful: big-format retail, fuel, local sourcing and a long runway of consumer traffic.

Costco’s broader European expansion remains limited compared with its U.S. footprint, which makes each new location more meaningful for the company’s long-term growth narrative. With roughly 900 warehouses in 14 countries and only five in Spain, every new opening in the market can deepen brand awareness, reinforce membership economics and build a wider moat around value-seeking shoppers.

The market underestimates how much these projects matter in a slower-growth retail environment. For investors, the key takeaway is simple: the winners are likely to be the companies that supply the buildout, serve the traffic and adapt fastest to Costco’s arrival, while legacy retailers in northern Spain face a new and formidable price-and-scale competitor. Position early around the infrastructure and consumer-distribution names that can benefit from this opening wave.
