Restaurant Brands International is one of the largest restaurant companies in the world, with more than $35 billion in 2021 systemwide sales across a footprint that spans more than 28,000 restaurants and 100 countries. The firm generates revenue primarily from retail sales at its company-owned restaurants, royalty fees and lease income from franchised stores, and from its Tim Horton's supply chain operations. Formed in 2014 after 3G Capital's acquisition of Tim Horton's International, the Restaurant Brands portfolio now includes Burger King (19,250 units), Tim Horton's (5,300 units), and Popeyes Louisiana Kitchen (3,700 units). The 2021 acquisition of Firehouse Subs brings another 1,200 units and $1.1 billion in systemwide sales in-house.
