(Updates shares in paragraph 2, adds analyst comment in paragraph 3) Aug 7 (Reuters) - Restaurant Brands missed quarterly profit estimates on Thursday, hurt by aggressive marketing that boosted demand at Burger King and its other brands in the U.S. and international markets. U.S.-listed shares of the company fell 4% after Restaurant Brands posted an adjusted profit of 94 cents per share, below analysts' estimates of 97 cents, as per data compiled by LSEG, as supply chain and commodity costs also surged. The company's profit miss "highlights the tough terrain quick service restaurants are navigating as cost-conscious consumers continue to pull back," said Zak Stambor, analyst with eMarketer. The Trump administration's unpredictable trade policies have disrupted business operations and shaken consumers, especially lower-income groups, who are increasingly seeking bargains and scaling back dining out plans as they grapple with inflation.
