Even as Starbucks has been expanding aggressively in recent years—adding 1,677 stores in fiscal 2015 for a total of 23,043 in 68 countries—it’s striving to make its coffee shops more attractive and efficient. It has grown its same-store sales: 7% on average over the past five years, compared with a rate of 4.6% for the coffee- and snack-shop industry, according to IbisWorld. “Existing stores are becoming larger and more productive over time,” says Dan Davidowitz, chief investment officer and portfolio manager at Polen Capital, overseeing $9 billion in assets. And Starbucks is applying its methods to make each new store it opens better than the last. “We do not believe the company is nearing saturation, because its new stores are more profitable and have higher returns on investment than ever before,” Davidowitz adds.

The company has been increasing foot traffic with heartier food options (and a loyalty rewards program) and using its app and mobile-ordering feature to speed up service. Starbucks has room to open 5% more stores a year in the Americas and “much more than that in Europe and Asia, which are still very underpenetrated,” Davidowitz says. While he thinks Starbucks’ EPS growth could slow from the 30% it has averaged for the past five years, he still expects earnings to more than double by 2021, “enough conservatively estimated to get us to a strong double-digit return.” It also pays a dividend yielding more than 1%.
