Dunkin' is permanently closing about 800 locations throughout the country — about eight percent of its restaurants in the U.S.

The company detailed the changes in its quarterly earnings report on Thursday.

Dunkin' described the closures as "real estate portfolio rationalizations." It also said the locations have low sales volume and represent only two percent of its U.S. sales last year.

More than half of the closures are in Speedway convenience stores — a change Dunkin' previously announced in February.

The company said it may permanently close about 350 locations outside of the U.S.

The announcement comes a day after McDonald's said it would close around 200 locations, most of them in Walmart stores.
