Century Aluminum Company Q2 2026 Earnings Recap

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.
