While Krispy Kreme and Dunkin' share the word "doughnuts" or "donuts" in their name, the two have completely different business models, however, BGB Securities analyst Sam Yake told


recently. "Dunkin' has successfully evolved into a destination restaurant" like

and gets 60% of its revenue from driving repeat customers who go everyday as part of their lifestyle.

By comparison, 88% of retail sales at Krispy Kreme is just doughnuts, and the brand has not been able to evolve from a doughnut-only shop. The average customer visit at Krispy Kreme is once per month, whereas at Dunkin' it's much more, Yake estimated, at six to seven times per month.

Starbucks gained 3.9% to $40.47 on Thursday,

Dunkin' Brands, which also operates the Baskin Robbins ice cream chain of stores, sells coffee, doughnuts and other food items. It boasts a loyal following, particularly in the northeastern U.S. where its stores are concentrated. Nearly 6,700 Dunkin' Donuts stores are in the Northeast, with another 100 or so spread around other parts of the country, but there are virtually no stores in the far West of the U.S. There are also more than 3,000 international locations of Dunkin' Donuts.

"Dunkin' Donuts doesn't have much coverage in the West, there seems to be a lot of potential to expand in that area," Josef Schuster, founder of Chicago-based IPO investment firm IPOX Schuster, told



Baskin Robbins has more stores outside the U.S. than within; with nearly 6,500 stores around the world, just over 2,500 are domestic.

Dunkin' has widely been viewed as a growth stock as the company intends to expand in key geographic areas like Philadelphia, Chicago and South Florida. Stores west of the Mississippi River may be the next big focus of expansion.

Brand Keys

ranked Dunkin' Donuts as the coffee brand with the most customer loyalty and engagement. Starbucks ranked second on the list, followed by McDonald's and Tim Horton's.
