Jack in the Box CEO Darin Harris said: “I am very pleased with the momentum of our top line performance to close 2022, which we have seen continue into the first several weeks of Q1, and the consistency we showed throughout the year in driving sales and improving traffic, as we continue to remain careful on the price we are taking to maintain a consistent value equation for our guests.

“We continue to navigate operational headwinds, but Jack and Del Taco franchisees and operators showed their ability to be resilient and manage through them effectively all throughout 2022.

“While we will continue to attack the inflationary impact on margins, our top line fundamentals, operational focus, and expectation for positive net unit growth for Jack all demonstrate that 2023 will be a big year for our company and another positive step in the transformation of the Jack brand.”
