BLACK DIAMOND GROUP LIMITED

NOTICE AND ACCESS NOTIFICATION TO SHAREHOLDERS

You are receiving this notification as Black Diamond Group Limited (“Black Diamond”) has decided to use the notice and access model (“Notice and Access”) for the delivery of meeting materials to its shareholders who do not hold their common shares of Black Diamond in their own name (the “Beneficial Shareholders”) in respect of its annual meeting of shareholders to be held on May 7, 2026 (the “Meeting”). Under Notice and Access, Beneficial Shareholders still receive a voting instruction form enabling them to vote at the Meeting. However, instead of receiving a paper copy of Black Diamond’s information circular – proxy statement dated March 23, 2026 (the “Information Circular”), Beneficial Shareholders are receiving this notice with information on how they may access the Information Circular electronically. The use of this alternative means of delivery is more environmentally friendly as it will help reduce paper use and it will also reduce Black Diamond’s printing and mailing costs.
