The company's Tim Hortons franchise is having some hiccups, but its other two brands are doing well. Specifically, in Q3 2019, Tim Hortons had comparable sales of -1.4%, which was worse than the poor 0.6% in the comparable period in the prior year. On a bright note, Burger King and Popeyes Louisiana Kitchen, respectively, had strong comparable sales of 4.8% and 9.7%.
