1154 ET - Taco Bell sales look like they'll maintain their momentum as the chain puts its food safety issues behind it, UBS analysts say in a research note. Yum Brands just reported a 7% jump in same-store sales for 2Q at its taco-slinging subsidiary, reflecting solid product innovation, compelling value offerings, strong operational execution and gains in its digital channel and loyalty program, the analysts say. The near-term impact of cyclospora-related illnesses linked to lettuce it served was meaningful, hitting the July 18 weekend the hardest, they say. But trends have steadily improved, with a roughly 50% recovery in average sales from the worst levels, showing the pressure is transitory, the analysts say.
