Dear Sirs/Mesdames:

RE: Groupe Dynamite Inc. (the “Company”)

We refer to the short form base shelf prospectus of the Company dated April 20, 2026 relating to the offer and sale, from time to time, of subordinate voting shares, preferred shares, debt securities, subscription receipts, warrants or units (the “Prospectus”).

We, Deloitte LLP, consent to being named and to the use, through incorporation by reference in the Prospectus, of our report dated March 31, 2026 to the Shareholders and the Board of Directors of the Company on the following financial statements:

Consolidated statements of financial position as at January 31, 2026 and February 1, 2025;

Consolidated statements of net earnings and comprehensive income, consolidated statements of changes in equity and consolidated statements of cash flows for the years then ended, and notes to the consolidated financial statements, including material accounting policy information.

We report that we have read the Prospectus and all information specifically incorporated by reference therein and have no reason to believe that there are any misrepresentations in the information contained therein that are derived from the financial statements upon which we have reported or that are within our knowledge as a result of our audit of such financial statements. We have complied with Canadian generally accepted standards for an auditor's consent to the use of a report of the auditor included in an offering document, which does not constitute an audit or review of the Prospectus as these terms are described in the CPA Canada Handbook – Assurance.

Yours truly,

/s/ Deloitte LLP[1]
