Burger King fuels RBI growthPhoto: Burger KingAugust 6, 2026 by Valerie GrittonSummarize with ChatGPT Grok Perplexity ClaudeRestaurant Brands International (RBI), the parent company of Burger King, Tim Hortons, Popeyes and Firehouse Subs, reported strong second-quarter 2026 results, driven largely by Burger King's continued momentum, the company said in a press release. Burger King posted 6.4% systemwide sales growth and 3.8% comparable sales growth, with Burger King U.S. leading the portfolio of brands at 8.5% U.S. comp sales growth while its international markets posted a 5.5% gain. The company said it remains on track to achieve its long-term goal of more than 8% organic adjusted operating income growth in 2026. Tim Hortons delivered modest same-store sales growth, while revenue and operating income increased. RBI's international markets remained a growth engine for the company and was driven by higher royalty revenue from its Burger King and Popeyes restaurants and the return of franchise royalty payments from Burger King China following the formation of a joint venture earlier this year.
