Wingstop shares fell 5.2% after Q1, as investors were disappointed by a sharp 8.7% decline in same-store sales and management’s reduced full-year outlook, now anticipating “low single digit” declines. Execution progress and margin gains were outweighed by concerns about sales deceleration and weak near-term guidance.

• Domestic same-store sales dropped 8.7% in Q1, declining sequentially during the quarter, with management citing atypical winter weather and higher gas prices impacting traffic.
• Full-year same-store sales outlook was revised downward, now expected to be "down low single digits" versus prior expectations for growth.
• Despite the sales weakness, adjusted EBITDA grew double digits, and brand partner margins “strengthened” in the quarter.
• The company opened 97 net new restaurants in Q1, representing 17% unit growth year-over-year.
• Management highlighted operational improvements from the Wingstop Smart Kitchen and ongoing investments in digital and loyalty initiatives, but expects sales trends to recover only in the second half.
