DALLAS — Christina Clarke has been named chief marketing officer at Wingstop, Inc.

Ms. Clarke has been a key driver of growth since joining the chain as interim c.m.o. last year, said Charlie Morrison, chairman and chief executive officer at Wingstop.  In February, she helped launch the “Where Flavor Gets its Wings” campaign. Along with increased delivery rollout and expanded digital sales mix, the campaign contributed to same-store sales growth of 12.3% during the third quarter. System-wide sales increased 21.6%.

“Cultivating and promoting talent within our organization is a cornerstone of the path toward long-term growth and success at Wingstop,” Mr. Morrison said. “Christina has contributed tremendously to our marketing strategy.”

Advertising is a key part of Wingstop’s plan to become a top 10 global restaurant brand. The company recently doubled its marketing spend, resulting in a 16.6% increase in same-store sales since 2017.

Ms. Clarke brings more than a decade of experience at PepsiCo to her new role. Before joining Wingstop, she was senior director of marketing for Frito-Lay North America. She was promoted alongside Donnie Shaw, senior vice-president of people, who previously was vice-president of human resources.

“Both Christina and Donnie embody the leadership qualities that will continue to help us execute against our growth strategy,” Mr. Morrison said.
