What Algoma Steel does

Algoma Steel is a publicly traded Canadian steel manufacturer (NASDAQ:ASTL, TSX:ASTL) founded in 1901 and headquartered in Sault Ste. Marie, Ontario. It operates a fully integrated steelworks that completed its transition from legacy blast furnace / basic oxygen steelmaking to Electric Arc Furnace (EAF) steelmaking in 2025, with first EAF steel produced July 10, 2025 and decommissioning of integrated assets (Blast Furnace No. 7 and Coke Batteries No. 7, 8, 9) completed by January 2026. The company's core production assets are the Direct Strip Production Complex (DSPC) for continuous casting and direct hot rolling of sheet, a modernized Plate Mill capable of producing plate up to 154 inches (3,912 mm) wide (Canada's only discrete plate producer), an in-plant heat-treating facility, a Ladle Metallurgy Furnace, and two new fume treatment plants supporting the EAF transition. Production capacity is approximately 2.8 million liquid tonnes per year, ramping to a target of 3.7 million tons per year at full EAF operation, with the new EAFs adding roughly 700,000 tons of finished steel capacity.

Algoma produces steel plate (Volta Plate, AR225, AlgoTuf 450F/500, AlgoLaser, AlgoGrip, The Heavies, Armour Plate to MIL-DTL-46100E(MR) Class 1, Algoma 100) and steel sheet (Hot-Rolled Sheet via DSPC, AR200, Cold-Rolled Sheet including HSLA 60ksi), with all EAF-produced steel sold under the Volta brand, marketed as low-carbon steel with up to 70% lower CO2 emissions, powered by Ontario's clean electricity grid and produced primarily from recycled scrap. Revenue is generated through quote-based B2B sales of plate and sheet on a per-ton basis, supplemented by by-products (slag, mill scale, coke products) and surplus equipment sales, and historically by carbon-credit sales that have been disrupted by Ontario's carbon-pricing reset following the EAF transition. The company sells direct to enterprise customers across automotive, construction, defence, energy, infrastructure, manufacturing, and transportation verticals, with a Burlington, Ontario sales office serving North American customers and a Head Office / steelworks in Sault Ste. Marie. Defence is the primary segment, supported by armour plate and naval procurement under Canada's National Shipbuilding Strategy, with Caterpillar (18 consecutive years of Supplier Excellence certification), Roshel, Davie, Hanwha Ocean, the Canadian Armed Forces, and the U.S. Armed Forces as anchor customers and partners.

Revenue model

1. Steel Product Sales (Plate and Sheet): Primary revenue stream from sale of steel plate (Volta Plate — Canada's only discrete plate producer), hot-rolled sheet (Volta Hot-Rolled Sheet), and cold-rolled sheet products to industrial customers. Includes proprietary branded products AlgoTuf, AlgoLaser, AlgoGrip, AR200, AR225, and The Heavies. Unit-based pricing on per-ton basis.
2. By-Products and Surplus Equipment Sales: Revenue from sale of by-products (slag, mill scale, coke products) and surplus equipment generated from steelmaking operations through a Request for Quotation process.
3. Carbon Credits and Offsets: Historically generated carbon credits from efficient operations that could be sold to other industrial emitters; this was impacted by Ontario's intensity-based carbon pricing system reset that prevented credit generation following the EAF transition.

Core offering

Algoma Steel is a fully integrated Canadian steel manufacturer that produces hot-rolled sheet, cold-rolled sheet, and discrete steel plate products via Electric Arc Furnace (EAF) steelmaking using primarily recycled scrap metal and Ontario's low-emissions electricity grid. Its products serve automotive, construction, defence, energy, infrastructure, manufacturing, and transportation end-markets, with branded specialty products (AlgoTuf, AlgoLaser, AlgoGrip, AR200, AR225, Algoma 100, Armour Plate) and the Volta low-carbon steel sub-brand.

Product overview

Algoma Steel offers a single integrated product portfolio centered on steel plate and sheet (hot-rolled and cold-rolled), marketed under the Volta™ sub-brand for all steel produced through its Electric Arc Furnace (EAF) operations. The portfolio is structured as a core plate-and-sheet offering plus specialty sub-products and a sub-brand layer: the core plate line comprises AR225, Heat-Treated Plates (AlgoTuf 450F and AlgoTuf 500), AlgoLaser, AlgoGrip, and The Heavies; the core sheet line comprises Hot-Rolled Sheet – DSPC, AR200, and Cold-Rolled Sheet (including Cold-Rolled 60ksi HSLA Formable Steel); specialty products include Algoma 100 for transportation and MIL-DTL-46100E Class 1 Armour Plate for defence; and the Volta™ sub-brand wraps EAF-produced plate (Volta Plate) and EAF-produced hot-rolled sheet (Volta Hot-Rolled Sheet). Adjacent offerings include industrial By-Products & Surplus Equipment sold via Request for Quotation. Together these share Algoma's modernized Plate Mill (up to 154"/3,912 mm wide) and DSPC as common production assets, now fully transitioned to EAF steelmaking for up to 70% lower carbon intensity.

Direct peers

• Cleveland-Cliffs: Largest flat-rolled steel producer in North America and a primary competitor to Algoma in automotive, construction, and infrastructure-grade steel. Also investing in green steel and EAF technology, making it a directly comparable transformation peer.
• Nucor: Largest steel producer in the United States and the dominant EAF-based mini-mill operator. Directly comparable on technology stack (EAF), sheet and plate product mix, and end-market exposure to automotive, construction, and energy.
• Steel Dynamics: U.S.-based EAF steelmaker producing flat-rolled steel, structural steel, and specialty products. Closely comparable on EAF technology, recycled scrap feed, and competitive positioning in North American flat-rolled sheet markets.
• Stelco Holdings: Hamilton, Ontario-based flat-rolled steel producer and Algoma's most direct Canadian competitor. Both serve similar North American automotive, construction, and industrial customers with EAF-produced flat-rolled steel.
• SSAB: Swedish specialty steel producer and global leader in green steel transition with its HYBRIT initiative. Directly comparable on EAF technology adoption, specialty plate focus (including Hardox abrasion-resistant steel), and decarbonisation strategy mirroring Algoma's Volta brand.
• Gerdau: Brazil-headquartered long and flat-rolled steel producer operating the largest EAF mini-mill network in the Americas. Comparable on EAF technology, recycled scrap feed, and serving North American automotive, construction, and industrial OEM customers.
• Commercial Metals Company (CMC): U.S.-based EAF steelmaker and metals recycler with growing flat-rolled and structural steel operations. Directly comparable on EAF technology, scrap-based production, and serving construction and infrastructure end markets.

Broad incumbents

• U.S. Steel: Historic integrated steelmaker with broad portfolio across flat-rolled, tubular, and stainless products. Comparable end-market exposure and ongoing EAF investments under Nippon Steel ownership make it an incumbent comparable, though far larger in scale than Algoma.
• ArcelorMittal: World's largest steelmaker with broad portfolio including automotive, construction, and packaging steels. Incumbent comparable on global flat-rolled production scale and ongoing decarbonisation investments, though much broader and geographically diversified than Algoma.

Regional players

• Ternium: Latin American flat and long steel producer serving automotive, construction, and industrial markets. Comparable on integrated steelmaking operations and end-market mix, though geographically focused on Mexico and South America rather than competing directly in Canada/U.S. plate markets.
