1044 ET - Papa John's CEO Todd Penegor says the company's turnaround strategy is working, even though it's not progressing as fast as he'd like. "We are seeing encouraging signs of progress," he says on a call with analysts, citing a growing membership program, better-optimized supply chain, and investments in AI that have improved the customer ordering experience. "At the same time, we felt the impacts of the softer consumer backdrop and highly promotional QSR environment, which have continued to challenge our financial performance," Penegor says. "While our focus is unrelenting, it's clear that our transformation is taking longer than expected." Shares sink 15%.
