Algoma Steel Group reported heavy losses for the three and twelve months ended December 31, 2025, while completing its transition to electric arc furnace (EAF) steelmaking. Fourth quarter results were described as in-line with previously announced expectations despite severe trade and transition headwinds.
Fourth quarter revenue was $455.0 million, down from $590.3 million a year earlier, with shipments falling 31.0% to 378,533 tons. Net loss widened to $364.7 million from $66.5 million, driven by Section 232 tariff costs, lower volumes, higher per‑ton costs and transition-related depreciation, stranded inventory and severance.
For 2025, revenue was $2,085.7 million versus $2,461.7 million the prior year, and net loss expanded to $984.9 million from $139.0 million. Adjusted EBITDA swung to a loss of $261.4 million from a $22.4 million gain, reflecting reduced shipments, a large non‑cash impairment and $225.0 million of tariff costs. Cash fell to $77.5 million, though Algoma highlighted $194.5 million of undrawn revolver capacity and $417 million available under a $500 million government-backed liquidity facility as it ramps its new EAF platform and pivots toward higher‑value discrete plate production.
