[6-K] BIRKS GROUP INC. Current Report (Foreign Issuer)

Rhea-AI Filing Summary

Birks Group Inc. filed a Form 6-K disclosing shareholder voting tallies and a communication from its auditor, KPMG LLP. The filing furnishes and incorporates a KPMG letter (Exhibit 16.1) dated September 24, 2025. KPMG communicated material weaknesses in the company’s internal control over financial reporting related to: (1) insufficient accounting and financial reporting personnel to segregate duties for certain reconciliations and journal entries; (2) inadequate design of management review controls and retention of documentary evidence for assessments of operations and inventory reserves; and (3) an insufficient control over review of classification of a cash flow transaction. Voting results included large majorities of Votes For (e.g., 83,371,520; 83,373,520) with non-votes of 966,150. The filing does not state remediation steps or timelines.

Positive

• KPMG letter was furnished and incorporated as Exhibit 16.1 to the Form 6-K, demonstrating auditor communication has been formally filed
• Shareholder voting results are disclosed, showing clear vote tallies with substantial 'Votes For' on recorded items

Negative

• KPMG reported material weaknesses in internal control over financial reporting related to segregation of duties for reconciliations and journal entries
• Insufficient design of management review controls and inadequate retention of documentary evidence for assessments of operations and inventory reserves
• Insufficient control over review of classification of a cash flow transaction, increasing risk of misclassification in financial statements
• No remediation plans or timelines disclosed in the filing, leaving uncertainty about resolution and the timing to restore effective controls

Insights

Financial Analyst

TL;DR: Auditor flagged multiple material weaknesses in controls, which raises short-term reliability concerns for reported financials.

The auditor, KPMG, identified three specific design and resource-related material weaknesses affecting reconciliations, journal entry segregation, management review evidence, and cash flow classification review. These weaknesses materially affect the company’s internal control over financial reporting and consequently increase the risk of misstatements in historical and interim financial statements until remediated. The filing includes shareholder vote tallies but does not provide remediation plans, timelines, or management’s response, limiting clarity for valuation adjustments or near-term credit assessment.

Risk & Controls Analyst

TL;DR: Identified control design and resourcing gaps indicate elevated operational and reporting risk requiring prompt remediation.

KPMG’s communication specifies lack of adequate segregation of duties, weak management review evidence retention, and an insufficient control over cash flow classification review. These are control design and personnel issues that commonly require governance action, staffing changes, and documented remediation to restore control effectiveness. The absence of disclosed remediation steps or timelines in the filing increases uncertainty about the company’s ability to correct these deficiencies quickly.

1. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

On September 18, 2025, the Annual Meeting of Shareholders (the “Meeting”) of Birks Group Inc. (the “Company”) was held in Montreal, Quebec. The shareholders of record at the close of business on July 25, 2025 (the “Record Date”) were entitled to vote at the Meeting. As of the Record Date, the Company had 11,876,717 Class A voting shares outstanding (which entitle the holder to one vote per share), 7,717,970 Class B multiple voting shares outstanding (which entitle the holder to 10 votes per share) and no preferred shares outstanding.

Imbriglio, and Deborah Shannon Trudeau, to hold office until the next succeeding annual meeting of shareholders of the Company or until their successors are elected or appointed. The election of directors by the shareholders was by the following votes:

Name		Votes For		Votes Against		Votes Withheld		Non-Votes
Niccolò Rossi di Montelera		83,371,520		7,405		n/a		966,150

The shareholders authorized the appointment of Grant Thornton S.E.N.C.R.L. as the Company’s independent auditors and authorized the directors to fix Grant Thornton S.E.N.C.R.L.’s remuneration by 84,152,893 votes in favor, 190,409 votes against, 1,773 votes withheld/abstained and 0 non-votes.

2. CHANGE IN COMPANY’S AUDITORS

On September 9, 2025, the Company issued a press release (the “Press Release”) announcing that the board of directors of the Company (the “Board”) 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”) and thus effectively ending KPMG LLP’s (“KPMG”) term as auditors. The Press Release was furnished on Form 6-K with the Securities and Exchange Commission (“SEC”).

KPMG has served as the Company’s independent auditors since January 25, 2000. On July 29, 2025, following the issuance of KPMG’s audit report on the Company’s consolidated financial statements for the fiscal year ended March 29, 2025, the Company launched a competitive request for proposal (“RFP”) process inviting KPMG and other 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. The Company reviewed the various proposals received, which led to the Board’s recommendation of the appointment of Grant Thornton as the Selected Auditors.

KPMG’s audit reports on the financial statements of the Company as of and for the fiscal years ended March 29, 2025 (“fiscal year 2025”) and March 30, 2024 (“fiscal year 2024”) did not contain any adverse opinion or disclaimer of opinion, nor were such reports qualified or modified as to uncertainty, audit scope or accounting principles. During fiscal year 2024, fiscal year 2025 and to the date of the change of auditors, there were:

(i) no “disagreements”, as such term is defined in Item 16F(a)(1)(iv) of Form 20-F (and the related instructions thereto), between the Company and KPMG on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreement, if not resolved to the satisfaction of KPMG, would have caused it to make reference to the subject matter of such disagreement in connection with its audit reports on the Company’s financial statements; and

(ii) no “reportable events”, as such term is defined in Item 16F(a)(1)(v) of Form 20-F, except for the KPMG’s communication of material weaknesses in internal control over financial reporting as of March 29, 2025 related to (i) the lack of sufficient accounting and financial reporting personnel to appropriately segregate duties in the preparation and review of certain account reconciliations (purchases and leases) and journal entries, (ii) the insufficient design of certain management review controls (assessment of future operation and inventory reserves) due to the inadequate retention of documentary evidence including management’s assessment related to the completeness and accuracy of the underlying information, and (iii) the insufficient design of a control related to the review of the classification of a cash flow transaction.
