Restaurant Brands International beat Q1 2026 Wall Street estimates, behind an aggressive domestic Burger King turnaround and steady international expansion. Total revenue rose 7.3% year-over-year to $2.26 billion, while adjusted diluted EPS climbed 14.6% to $0.86, beating the $0.83 consensus. Portfolio-wide comparable sales increased 3.2%, anchored by a 5.8% same-store sales surge at Burger King U.S. under its "Reclaim the Flame" modernization push and a 5.7% international gain. Brand performance remained mixed elsewhere, as Canadian macro softness slowed Tim Hortons to 1.6% comparable growth, and Popeyes cratered 6.5%.
Restaurant Brands International fully reaffirmed its full-year 2026 outlook while balancing domestic turnaround momentum against localized soft consumer demand. The company reiterated its full-year guidance of 8% or more in organic adjusted operating income growth, supported by a $500 million share repurchase target. Management detailed specific 2026 financial parameters, guiding segment G&A to $600 million–$620 million, net adjusted interest expense to $500 million–$520 million, and capital expenditures plus franchise inducements to roughly $400 million.
Long-term, QSR remains anchored to its 2028 growth algorithm, targeting minimums of 3% comparable sales growth, 5% net restaurant growth, and 8% adjusted operating income growth.
RBI is one of the largest fast-food restaurant chains in the world, and it is a combination of four iconic brands - Burger King, Tim Hortons, Popeyes, and Firehouse Subs. In addition, the company operates International operations for all these brands outside U.S. and China. QSR also established a new operating segment after the acquisition of Carrols Restaurant Group Inc and Popeyes China.
Burger King's restaurants fall into the quick service restaurants category in the U.S. and Canada - that features flame-grilled hamburgers, fish and chicken combos, french fries, soft drinks, and other affordable food items. Burger King restaurants appeal to a wide range of consumers, with multiple dayparts and product platforms appealing to varied customer groups. The fast-food chain competes with McDonald's and Wendy's in the Fast Food Hamburger Restaurant (FFHR) category.
Tim Hortons restaurants are quick-service restaurants with a menu that includes premium blend coffee, tea, espresso-based hot and cold specialty drinks, fresh baked goods, including donuts, bagels, cookies and pastries, grilled paninis, classic sandwiches, wraps, soups, and more. These account for operations in the U.S. and Canada.
Popeyes Louisiana Kitchen is a chain of quick-service restaurants that distinguish themselves with a unique Louisiana-style menu that features spicy chicken, chicken tenders, fried shrimp and other seafood, red beans and rice, and other regional items. Popeyes is a highly differentiated QSR brand with a passion for its Louisiana heritage and flavorful, authentic food. Restaurant Brands International acquired Popeyes Louisiana Kitchen (PLK) in March 2017. These account for operations in the U.S. and Canada
Firehouse Subs is a leading player in the QSR sandwich category in North America. This brand was acquired by QSR on December 15, 2021. These account for operations in the U.S. and Canada
Below are key drivers of Restaurant Brands International's value that present opportunities for upside or downside to the current Trefis price estimate:

Company-operated restaurants are low-margin businesses (~10-15% operating margin) as compared to franchised restaurants (~70% operating margin). The difference in margins is mainly because of the extra costs involved with company-operated restaurants, such as employees and operational costs, which are absent from franchised restaurants.
Approximately 95% of system-wide restaurants were franchised. As Restaurant Brands International looks to become a 100% franchised model, it will mean lower revenues but higher margins for the company.
The company benefits from a diversified portfolio of well-recognized brands with strong international appeal. Burger King and Popeyes, in particular, offer significant white space for expansion in emerging markets.
RBI’s investment in digital platforms and loyalty programs is driving higher customer engagement, improved order frequency, and better data-driven decision-making, strengthening long-term growth potential.
Consumers continue to favor quick-service restaurants due to convenience and affordability, especially in uncertain economic environments. RBI is well-positioned to benefit from this trend given its global scale and strong value offerings.
The company is aggressively expanding in international markets, where QSR penetration remains relatively low. This strategy is expected to drive long-term system-wide sales growth and diversify revenue streams beyond North America.
RBI is leveraging technology to enhance ordering convenience and operational efficiency. Growth in mobile ordering, delivery partnerships, and loyalty ecosystems is expected to remain a key driver of comparable sales growth.
