Alongside these changes, Donald Birak will step down as a director, effective Nov. 4, 2026. The company sincerely thanks Mr. Birak for his service and valuable support throughout Arc's transition to a mineral royalty company and its relisting on the TSX Venture Exchange. The board wishes him every success in his future endeavours. The company also thanks Mr. York for his leadership as chair during this important period; his continued service as a director will provide valuable continuity as Arc enters its next phase of growth.

Adam Davidson, chief executive officer and executive director of Arc, commented: "We are delighted to welcome Ruby to the board and for Greg to take on the role of chair. Ruby brings a valuable combination of royalty investment experience and technical mining expertise, which will complement the experience already on our board. Having worked with Greg previously, I am confident that he will bring strong leadership and commercial judgment to the role of chair. We believe that bolstering these key areas of our business will help to support our strategy as we continue to build and diversify Arc's royalty portfolio.

"Additionally, on behalf of the Arc board, I would like to thank Jeff for his leadership during an important period in the company's development, particularly through our transition to a mining royalty company. We are pleased that he will remain on the board as we continue to execute on our growth strategy. I would also like to thank Don for his contributions, service and support throughout this transition."
