Century Aluminum Company Earnings Recaps
Q2 2026
Aug 8, 2026
Shares jumped 9.2% following a solid quarter driven by the on-time completion and full ramp-up of key capacity expansions at Mount Holly and Grundartangi, which positioned the company to benefit from strong market conditions and favorable pricing.
Key takeaways
- Mount Holly expansion completed on time and on budget, adding nearly 10% to U.S. aluminum production; full benefit to be seen starting Q3.
- Grundartangi’s Line 2 restarted smoothly and ahead of schedule, running conservatively until replacement transformers arrive in Q4.
- Jamalco brought a new power turbine online, enabling self-generated energy and reducing reliance on expensive grid purchases.
- Market fundamentals remain robust with LME prices near preconflict levels and strong U.S. demand driven by infrastructure, aerospace, defense, and reshoring trends.
- Some operational headwinds persist, including plant instability post-restart at Mount Holly and lower quality bauxite at Jamalco, but both are being actively managed.
Q1 2026
May 8, 2026
Century Aluminum’s shares fell 5.9% following earnings as investors reacted negatively to a cautious outlook and headwinds in the alumina segment, which overshadowed solid operational progress and the Mt. Holly expansion ramp-up.
Key takeaways
- Production ramp-up at Mt. Holly expansion is on schedule, with full impact expected in Q3; Q2 includes incremental volumes but no full run rate yet.
- Restart of Potline 2 at Grundartangi proceeding as planned, with full production expected after new transformers arrive in Q4.
- Jamalco refinery still recovering from Hurricane Melissa; faced challenges with lower quality bauxite and a weaker global alumina market due to Middle East conflict.
- Increased energy costs partially offset by hedges; however, margin pressures emerged due to raw material and fuel price volatility.
- Management highlighted strong safety and operational execution but maintained a cautious outlook amid global supply disruptions and market uncertainties.
