Algoma Steel Group Inc.

Algoma is a producer of hot and cold rolled steel products, including coiled sheet and plate, located on the Great Lakes in Sault Ste. Marie, Ontario, Canada. The Company is a flat-rolled steel producer in North America and the only producer of discrete plate in Canada, with an estimated annual liquid steel production capacity of approximately 2.8 million tons as of December 31, 2025. Algoma supplies customers primarily in the automotive, construction, energy, defense and manufacturing sectors. The Company currently operates one EAF. Construction of a second EAF is expected to be completed in the first half of 2026, with commissioning and ramp-up anticipated thereafter. The transition to EAF steelmaking has replaced production from Blast Furnace No. 7, which was decommissioned in January 2026. Blast Furnace No. 6 remains idled. Algoma’s downstream facilities include its Direct Strip Production Complex ( DSPC ) for production of sheet steel products, constructed in 1995 at an approximate cost of C$450 million, and which integrates continuous casting and hot rolling. We also operate Canada’s only discrete plate rolling mill, which is 166 inches wide, as well as discrete plate heat treating. The Company’s sheet steel products include a wide variety of widths, gauges and grades, and are available in unprocessed form as hot rolled coil ( HRC ). Primary end users of sheet products include service centers, automotive, manufacturing, construction and tubular industries.
