Wingstop — Jul 29, 2025 release

Quarterly Dividend In recognition of the Company’s strong cash flow generation and our commitment to returning value to stockholders, on July 29, 2025, our board of directors approved an increase in the quarterly dividend payable to Wingstop stockholders from $0.27 to $0.30 per share of common stock, resulting in a total dividend of approximately $8.4 million. This dividend will be paid on September 5, 2025 to stockholders of record as of August 15, 2025. The following definitions apply to these terms as used in this release: Domestic average unit volume (“AUV”) consists of the average annual sales of all restaurants that have been open for a trailing 52-week period or longer. This measure is calculated by dividing sales during the applicable period for all restaurants being measured by the number of restaurants being measured. Domestic AUV includes revenue from both company-owned and franchised restaurants. Domestic AUV allows management to assess our domestic company-owned and franchised restaurant economics. Changes in domestic AUV are primarily driven by increases in same store sales and are also influenced by opening new restaurants. Domestic same store sales reflects the change in year-over-year sales for the same store restaurant base. We define the same store restaurant base to include those restaurants open for at least 52 full weeks. This measure highlights the performance of existing restaurants, while excluding the impact of new restaurant openings
