Altius Minerals is proud to announce that its common shares will be added to the S&P/TSX Composite, effective prior to the opening of trading on June 22, 2026. Brian Dalton, CEO, comments, “Inclusion in Canada’s premier market index, amongst a humbling list of Canada’s strongest public companies, represents an honour for the entire team at Altius. It is certainly fair to say that this achievement was not on our list of goals when we established Altius 29 years ago as a junior capital pool company. We would like to offer a sincere thank you to our shareholders for their long-term support and encouragement while also pledging to continue to work hard to find ways to grow enduring value on your behalf. I would also like to personally express my gratitude and congratulations to current and former colleagues for your incredible efforts and camaraderie.” Full PR: altiusminerals.com/_resource… $ALS.TO #Altius #Royalties #TSX #Index #Membership
