Why Subway Is Closing Another 500 U.S. Stores

Feeling the need to improve its store fleet amid intense competition in the sandwich industry, Subway is planning to close 500 U.S. locations this year, according to Bloomberg News.

Subway restaurants are small in size, but ubiquitous. The chain is the largest in the U.S. by store count of any quick-service chain with nearly 26,000 locations, well above the 14,000 McDonald’s mcd restaurants in this country. This has long been a point of pride for the company.

But as Subway faces more intense competition from everyone from a stronger McDonald’s to Panera Bread to Starbucks sbux , the company is finding it preferable to have nicer restaurants even if that means fewer of them. And competition isn’t limited to direct competitors—everyone from Target tgt to Walgreens wba has been adding take-out sandwiches to their food offering.

“We want to be sure that we have the best location,” Subway Restaurants CEO Suzanne Greco told Bloomberg News in an interview. “Store count isn’t everything.” The 2018 closings will come on the heels of similar moves in the last two years. A Subway spokeswoman told Fortune the company expects “having a slightly smaller, but more profitable footprint in North America” but with far more stores overseas.
