Birks Group Inc. (the "Company" or "Birks Group") (NYSE:BGI), today reported its sales results for the 8-week interim sales period ended December 27^th, 2025 (the "FY2026 Holiday Period"), resulting in an increase of 11.8% in net sales as compared to the corresponding period in FY2025. Comparable store sales for the FY2026 Holiday Period increased by 2.5% as compared to the corresponding period in FY2025.

The 11.8% increase in net sales for the FY2026 Holiday Period, as compared to the corresponding period in FY2025, is attributable in part to the acquisition of the European Boutique luxury timepieces and jewelry stores as well as an increase in sales of branded timepieces and Birks branded jewelry, both in retail and in e-commerce. The 2.5% increase in comparable store sales in the FY2026 Holiday Period versus the comparable period in FY2025 was also attributable to the performance of branded timepieces and Birks branded jewelry.

Mr. Niccolò Rossi di Montelera, Executive Chairman of the Board and Interim CEO of Birks Group, commented: "Our teams have delivered good sales results this holiday period as compared to the corresponding period last year, due in part to the acquisition of the European Boutique stores but also due to our strong retail and e-commerce performances. We are focused on building on this momentum and on delivering excellence in customer service. I would like to sincerely thank all our employees for their continued hard work and dedication."

Comparable Store Sales

We use comparable store sales as a key performance measure for our business. Comparable store sales include stores open in the same period in both the current and prior period. We include e-commerce sales in our comparable store sales calculations. Stores enter the comparable store calculation in their thirteenth full month of operation under our ownership. Stores that have been resized or relocated are evaluated on a case-by-case basis to determine if they are functionally the same store or a new store and then are included or excluded from comparable store sales, accordingly. Comparable store sales measure the percentage change in net sales for comparable stores in a period compared to the corresponding period in the previous year. If a comparable store is not open for the entirety of both periods, comparable store sales measure the change in net sales for the portion of time that such store was open in both periods. We believe that this measure provides meaningful information on our performance and operating results. However, readers should know that this financial measure has no standardized meaning and may not be comparable to similar measures presented by other companies.
