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.

The Company has provided KPMG with a copy of this 6-K and requested that KPMG furnish a letter addressed to the SEC stating whether or not it agrees with the Company’s statements. A copy of KPMG’s letter is furnished hereto as Exhibit 16.1 to this Form 6-K and is incorporated herein by reference.

GENERAL

The information included in this Form 6-K shall not be deemed filed for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act other than this Form 6-K, except as shall be expressly set forth by specific reference in such filing to this Form 6-K.
