Restaurant Brands International reported lower-than-expected earnings and revenue in the third quarter, with same-store sales for all four chains missing Wall Street estimates. Restaurant Brands' adjusted earnings per share and revenue fell slightly below analyst expectations. Burger King, Popeyes, and Firehouse Subs all reported same-store sales declines, falling short of expectations amid competitive challenges and changes in consumer spending. Tim Hortons reported domestic same-store sales growth, although it was lower than expected.
