But, on Thursday, those roles reversed. The Louisville, Kentucky-based restaurant company, parent of Taco Bell, Pizza Hut, KFC, and Habit Burger Grill, reported an 8% increase in US same-store sales at Pizza Hut for the fourth quarter. It was the chain's best quarter since the fourth quarter of 2010 when US same-store sales jumped 10%, analyst Mark Kalinowski wrote in a post-earnings brief. Taco Bell, on the other hand, reported a 1% increase in the fourth quarter. In a Thursday morning conference call with investors, Yum Brands CEO David Gibbs and Chris Turner, chief financial officer, credited a number of factors in Pizza Hut's rebound including pandemic-fueled pizza buys, improved digital channels, and the closure of underperforming legacy full-service "red roof" locations owned by a bankrupt operator.
