DEFSEC TECHNOLOGIES INC. ANNOUNCES BOARD CHANGES

Defsec Technologies Inc. has made changes to its board of directors as it heads into its 2027 fiscal year (FY) commencing Oct. 1, 2026.

Board changes

"We're delighted to welcome George Weber to the board as vice-chairman," said David Luxton, who moves from the role of executive chairman to non-executive chairman. "George (bio below) is a respected veteran of the defence and security industry, with extensive international experience in the public safety market from many years leading the Canadian and International Red Cross and Red Crescent. His background also includes experience in building software companies, which is highly relevant to our business at Defsec. As former chair of the Calian Group Ltd. (TSX: CGY) he brings long experience in governance of a large public defence company." Calian is one of Canada's premier defence and security companies with revenue of almost $900-million and a market cap approaching $1-billion.

Mr. Weber replaces Paul Fortin, who is retiring from the board. "Paul has served as a committed and faithful board member since Defsec first went public in 2021," added Mr. Luxton. "We are fortunate and grateful to have had the benefit of his service."

Sean Homuth, president and chief executive officer, added that: "George Weber adds substantially to our domain knowledge at the board level as we plan expansion into public safety markets in FY 2027. As well, his senior experience in public company governance is important to maturing board oversight as we continue to grow our business and position it in a dynamic operating environment, one that we believe is increasingly favourable to our business as a Canadian defence company.
