Domino's is a quick service pizza restaurant chain with thousands of locations worldwide. It franchises most of its stores. The company has three main sources of revenue: royalties from franchisees based on a percentage of sales; sales made in company-owned stores; and sales of food, equipment, and supplies to franchisees through the company's supply chain segment. The supply chain segment generates more than half of Dominos' revenue. Its largest food cost is cheese, which it purchases from a single supplier for United States stores. Outside of the United States, the company's largest markets include India, the United Kingdom, Mexico, Australia, and Turkey.
