NOTICE-AND-ACCESS

We are using "notice-and-access" to deliver the Circular and our audited consolidated annual financial statements for Fiscal 2024, accompanied by management's discussion and analysis (together with the Circular, the "Meeting Materials"), pursuant to an exemption obtained by the Company under the Canada Business Corporations Act. Under the notice and access procedure, you are still entitled to receive a form of proxy (or voting instruction form) enabling you to vote at the Meeting. However, instead of receiving paper copies of the Meeting Materials, you are receiving this Notice of Meeting which contains information about how to access the Meeting Materials electronically. The use of notice-and-access will directly benefit the Company by reducing our printing and mailing costs and is more environmentally friendly, as it reduces paper use. It also helps expedite our Shareholders' receipt of our Meeting Materials.

The Meeting Materials have been posted at https://investors.groupedynamite.com/annual-general-meeting-documents and under Groupe Dynamite's profile on www.sedarplus.ca. Before the Meeting, you may request paper copies of the Meeting Materials by following the instructions below:

Please note that you will not receive another form of proxy or voting instruction form; please retain your current one to vote your shares. Requests for paper copies should be received at least five business days prior to the proxy cut-off time, which is set for June 13, 2025, at 1:30 p.m. (Montreal time), in order to receive the Meeting Materials in advance of such date and the Meeting. To receive paper copies in advance of the voting deadline and Meeting, we recommend that your request be received by no later than 5:00 p.m. (Montreal time) on June 6, 2025.

After the Meeting, you may request paper copies of the Meeting Materials by calling us at 514-733-3962 or by email at [email protected]. We will send your Meeting Materials within ten calendar days after receiving your request.
