Business Overview
- • Core business model: Primary aluminum production with significant electric power cost exposure

- • Revenue impact from Hawesville facility sale: $200 million cash received plus 6.8% equity in Terawulf affiliate
- • Noted loss of approx. 84,000 tonnes alumina production in 2023 at Jamalco due to equipment failure, impacting gross margin by $30.4M
- • Operating disruptions: Grundartangi smelter potline idled for ~7 weeks reducing production by two-thirds; full resumption expected April 2026
- • Positive financial impact from US tariffs boost Midwest premium; tariffs increased to 50% effective June 2025
