On September 9, 2025, Birks Group Inc. (the “Company”) issued a press release announcing that the board of directors of the Company (the “Board”) has recommended the appointment of Grant Thornton S.E.N.C.R.L. (“Grant Thornton”) as auditors of the Company for the Company’s fiscal year ending March 28, 2026 (“fiscal year 2026”). The Board’s recommendation follows the launch of a competitive request for proposal (“RFP”) inviting qualified firms to submit proposals in order to evaluate and select auditors (the “Selected Auditors”) for fiscal year 2026 to serve until the next annual meeting of shareholders at such remuneration as may be fixed by the Board.

Pursuant to the Company’s Management Proxy Circular dated August 27, 2025 (the “Circular”), at the upcoming annual general meeting (the “Meeting”) of holders of Class A voting shares and Class B multiple voting shares of the Company (collectively, “Shareholders”) to be held on September 18, 2025, Shareholders are being asked to appoint the Selected Auditors as auditors of the Company for fiscal year 2026 to serve until the next annual meeting of shareholders or until a successor is appointed, and to authorize the Board to fix the Selected Auditors’ remuneration. This announcement serves as notice to the Shareholders that the Board has recommended Grant Thornton as the Selected Auditors. Accordingly, at the Meeting, Shareholders are being asked to approve the appointment of Grant Thornton as auditors of the Company for fiscal year 2026, and to authorize the Board to fix their remuneration.

The Company will not issue a new form of proxy or voting instruction form to Shareholders in respect of the Meeting. Shareholders who vote by proxy in advance of the Meeting in respect of the appointment of the “Selected Auditors” as auditors of the Company should be aware that they are voting in respect of the appointment of Grant Thornton and the authorization of the Board to fix their remuneration.

A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
