MEDIA RELEASE

Roshel Algoma Defence Partnership to Strengthen Canada’s
Defence Industrial Base
Two proven Canadian defence suppliers establish Roshel Algoma Defence Solutions Inc.
(“RADS” or “Roshel Algoma Defence”) to deliver sovereign ballistic steel solutions.
SAULT STE. MARIE, Ontario, April 7, 2026 — Algoma Steel Group Inc. (NASDAQ: ASTL; TSX: ASTL) (“Algoma Steel” or “Algoma”), a leading Canadian producer of steel plate and hot rolled sheet products and Roshel Inc. (“Roshel”), a Canadian-owned defence manufacturer of smart armoured vehicles, have formed Roshel Algoma Defence, a joint venture to establish a Canadian Centre of Excellence for Ballistic Steel Production. This partnership is purpose-built to deliver sovereign ballistic steel defence solutions, including full-cycle capabilities such as metal fabrication, forming, welding, and machining in Canada.
This new collaboration comes at a time of historic defence investment by the Government of Canada and aligns with the new Defence Industrial Strategy’s emphasis on strengthening sovereign industrial capabilities and Buy Canadian policies across major procurements. It also responds to the growing need for international defence companies to partner with a local, end-to-end supplier and service provider when operating in Canada.
By advancing a made-in-Canada approach to critical defence inputs, Roshel Algoma Defence will enable new, sovereign production of ballistic steel solutions to support defence procurements, including for Light Utility Vehicles (LUVs), the Domestic Arctic Mobility Enhancement (DAME) program, ships, submarines, and broader Canadian Defence needs. Additionally, Roshel Algoma Defence will support the use of ballistic steel across other industries, including infrastructure, marine, aerospace and security platforms while creating opportunities to export Canadian-made ballistic steel solutions to allied countries.
“Algoma Steel is ready to enhance Canada’s defence capacity, starting now. This partnership with Roshel puts our production capabilities, our workforce, and our Sault Ste. Marie facilities directly in service of Canada’s national security. Buy Canadian isn’t just a policy for us, it’s a strategy and a commitment to hundreds of good jobs.” — Rajat Marwah, CEO, Algoma Steel.
Roman Shimonov, the CEO of Roshel said, “Canada’s Light Utility Vehicle (LUV) procurement, which is expected to deliver thousands of vehicles for the Canadian Armed Forces, represents a cornerstone opportunity for Roshel, as a Canadian armoured vehicle manufacturer of combat proven platforms with a strong operational track record, to strategically partner with the Government of Canada to deliver a fully domestic solution using Canadian ballistic steel produced in Ontario.”
RADS is well-positioned to support over 500 workers, including new, high-quality manufacturing jobs and strengthening Canada’s skilled industrial workforce for the long term, reinforcing broader domestic supply chains, including those supporting automotive manufacturing such as Ford Motor Company and F-Series production in Oakville. Together, Roshel and Algoma Steel are advancing a made-in-Canada solution that will drive economic growth, reinforce national security, and deliver lasting benefits to Canadian workers, industry, and communities.
