The company reported revenues of $3.26 billion last year, or nearly three times that of Burger King. What's more, Tim Hortons churned out those sales with just under 4,500 locations worldwide, while Burger King has more than 13,000 restaurants around the globe. The Canadian coffee shop's efficiency is such that it outsold Dunkin' Donuts by a factor of almost eleven to one on a per-store basis.
