Dunkin’ Donuts unveiled a bold new expansion plan that includes doubling its current store count by adding 9,000 new shops. In the summer of 2016, the chain began a program of limiting its menu at some locations, remodeling stores and introducing new equipment, a strategy that has proved successful, said R.J. Hottovy, a Morningstar analyst who covers the brand, speaking on CNN.

“I’m sure they tested aspects of new concept to give them more confidence about expansion plans,” Hottovy said.

Dunkin’ Brands  CEO Nigel Travis provided no schedule for the launching of the new shops, but he did say that those will take drive-thrus to new levels of convenience.

A portfolio of 18,000 stores would put Dunkin’ Donuts far ahead of 7-Eleven, which has about 8,300 U.S. stores, and Starbucks, which operates nearly 14,000 here.
