Wingstop Inc. reported its fiscal first-quarter financial results showing a 15.7% increase in system-wide sales to $1.3 billion and a 221% rise in net income to $92.3 million, or $3.24 per diluted share. Adjusted net income, a non-GAAP measure, was $28.3 million, or $0.99 per diluted share. Despite challenging macroeconomic conditions, Wingstop achieved positive same-store sales growth of 0.5% in Q1, continuing a trend of strong transaction growth following two years of over 20% same-store sales increases. The company also reported an 11% increase in average unit volume, 1% same-store sales growth, and an 18% increase in store count. However, Wingstop joined other food companies in lowering its outlook amid economic concerns impacting consumer dining behavior. Following the earnings release, Wingstop's shares fell 4% in pre-market trading but later rose 10% during the day.
