Yum Brands missed analysts' estimates for second-quarter comparable sales and profit on Tuesday, hit by higher ingredient costs and muted demand that weighed on its businesses, including Taco Bell.

Lower-income consumers are pulling back visits from QSR concepts across the country, but not at Taco Bell. Not even close. The Mexican giant’s same-store sales rose 4 percent in Q1, outpacing the limited-service category by 4 percentage points.
