Algoma Steel Issues 2024 ESG Annual Report

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 publication of its second annual Environmental, Social, and Governance (“ESG”) report (the “Report”).

Michael Garcia, Algoma’s Chief Executive Officer said, “As detailed in our latest ESG report, we are driving change across our business to ensure that our transformation to become a North American leader in green steel is supported by robust governance processes, strong stakeholder relationships and investments in our people and communities.”

“We are now in the final phase of construction of our Electric Arc Furnace steelmaking facilities and plan to start commissioning by the end of the year. As we move closer to this milestone, we are moving closer to a future of sustainable steel making in which we expect to reduce emissions by up to 70%, while enhancing the quality of our product, increasing production, and realizing our purpose to build better lives through steel.”

Over the past twelve months, in parallel to progress on the construction of our Electric Arc Furnace (EAF) Steelmaking Facilities, Algoma has continued to advance the development and implementation of its ESG strategy. Led by a cross-functional working group, the Company conducted reviews of governance and enterprise risk management processes to ensure that ESG and climate change factors are embedded into business processes and aligned with best practice.

In the Report, Algoma builds on the benchmarks and reporting frameworks established in its inaugural ESG report, in alignment with the Sustainability Accounting Standards Board (SASB) and the recommendations of the Task Force on Climate-related Financial Disclosures.

The Report is available on Algoma Steel’s website at www.algoma.com.
