Building new stores and refreshing the old ones

Wingstop's management argued that the company's store network expansion is working. Wingstop opened 129 net new locations in the second quarter, and intends to continue this "record pace" for the foreseeable future. The total store network now stands at 2,818 locations.

It's not all roses and chicken tenders, though. Same-store sales fell 1.9%, reflecting tight consumer budgets in this unpredictable economy. However, there's a fix on the way.

Wingstop has been testing a new operating model in its company-owned stores, demonstrating shorter ticket completion times and robust same-store growth in the test kitchens. The Wingstop Smart Kitchen solution is rolling out to franchised locations over the next few quarters, with about 1,000 conversions already completed.
