SAULT STE. MARIE, Ontario, June 04, 2025 (GLOBE NEWSWIRE) -- Algoma Steel Group Inc. (NASDAQ: ASTL; TSX: ASTL) (“Algoma” or “the Company”), a leading Canadian producer of hot and cold rolled steel sheet and plate products, today announced the release of its 2024 Sustainability Report (the “Report”), covering a nine-month transition period from April 1 to December 31, 2024. The reporting period aligns with our 2024 financial reporting period, which now corresponds to a calendar year to reflect a consistent approach to our industry peer reporting.

Michael Garcia, Algoma’s Chief Executive Officer, commented, “At Algoma, sustainability is not a trend—it’s a strategic priority. As we are nearing the completion of our Electric Arc Furnace (EAF) project, we remain focused on operating safely, reliably, and responsibly while delivering high-quality Canadian-made steel. This transformation supports a stronger, low-carbon future for our business, our communities, and Canada’s steel industry.”

The 2024 Report highlights Algoma’s progress across key sustainability areas. The Company advanced enterprise risk management and integrated business planning frameworks strengthening governance, oversight of sustainability performance, and operational reliability. Algoma also reinforced its commitment to workplace safety, inclusion, and community engagement—while making significant strides toward completing Canada’s largest industrial decarbonization project. Once operational, the EAF is expected to reduce carbon emissions by approximately 70%, positioning Algoma to be a Canadian producer of green steel.

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.
