Watch Items from the Filing
Glencore, a 30% shareholder, accounted for approximately 44.0% of consolidated net sales in Q2 2026, down from 58.5% a year earlier.
Management concluded disclosure controls were not effective as of June 30, 2026, due to an unremediated material weakness in internal controls over the Jamalco joint venture consolidation.
Grundartangi's second potline remained impaired following an October 2025 transformer failure, cutting facility output by about two-thirds before a partial restart in April 2026; near-full production is expected by Q3 2026 end.
Section 232 tariffs on imported aluminum rose from 25% to 50% effective June 4, 2025, pushing the Midwest premium to historically high levels, which management says had a material positive impact on results.
Sale of the Hawesville facility for $200M cash plus a 6.8% minority stake in a Terawulf data-center JV generated a $287.9M gain in Q1 2026; Terawulf has since signed a 20-year, ~401MW lease with Anthropic PBC for the site.
