Yum Brands delivered fourth-quarter earnings Thursday that beat Wall Street expectations but were just shy on revenue, as fewer customers ate at its Pizza Hut chains.

Same-store sales were weaker than expected for the company in the quarter, rising 1 percent compared to an expected 1.7 percent, according to FactSet.

Taco Bell and KFC each saw same-store sales growth of 3 percent.

“KFC and Taco Bell had relatively strong performance in December, despite difficult U.S. industry conditions,” David Gibbs, CFO for Yum Brands, said in a statement Thursday.

The company’s third brand, Pizza Hut, suffered, however. Same-store sales fell 2 percent in the quarter.

In previous quarters, Pizza Hut has lagged behind. Analysts have blamed menu fatigue in the past for these soft sales.

The company posted earnings per share of 79 cents, excluding items, on $2.02 billion in revenue. Analysts had anticipated Yum to report earnings of 74 cents per share on $2.09 billion in revenue.

The latest-quarter results are Yum’s first since spinning off its China business in November.

Shares of the company were slightly positive in premarket trading on Thursday.
