SAULT STE. MARIE, Ontario, June 04, 2026 (GLOBE NEWSWIRE) — Algoma Steel Group Inc. (NASDAQ: ASTL; TSX: ASTL) (“Algoma” or “the Company”), a leading Canadian producer of steel plate and hot rolled sheet products, today announced the release of its 2025 Sustainability Report (the “Report”), covering the 12 months ended December 31, 2025. Algoma reports its sustainability performance on a calendar-year basis, aligned with its financial reporting practices.
Rajat Marwah, Algoma’s Chief Executive Officer, commented, “This Report reflects a pivotal year in Algoma’s nearly 125-year history. With the successful start-up of our first Electric Arc Furnace (EAF) and the subsequent wind-down of our blast furnace and coke oven operations, we have entered a new era as an EAF steel producer. Throughout this transformation, our focus has remained on operating responsibly, protecting the safety and well-being of our employees, and maintaining strong relationships with our customers, communities, and partners. Sustainability remains central to how we operate and how we create long-term value.”
The 2025 Report highlights Algoma’s progress across key sustainability areas during a year defined by transformation and a challenging trade environment. Milestones include the successful commissioning of the first EAF unit in July 2025, marking the beginning of Volta™ steel production, with construction of the second EAF unit on track for 2026. In January 2026, Algoma ceased operating and began decommissioning its Blast Furnace No. 7 and cokemaking assets, completing its shift to EAF steelmaking — Canada’s largest industrial decarbonization project. Once fully operational, the transition is targeted to reduce Algoma’s carbon emissions intensity by approximately 70%, positioning the Company as a leading producer of lower-carbon steel for North American and global markets.
Prepared in alignment with the Sustainability Accounting Standards Board (SASB) and the Task Force on Climate-related Financial Disclosures (TCFD), the Report underscores Algoma’s ongoing commitment to transparency, accountability, and long-term value creation.
