Executive summary

Century Aluminum Q2 FY26 — Full Capacity Achieved, Strong Market, and Oklahoma Project Progress

Century Aluminum delivered a strong second quarter, achieving full operating capacity across its Mt. Holly and Grundartangi plants ahead of schedule, capitalizing on robust market conditions with high LME and regional premiums. The company made significant progress on its Oklahoma smelter project, bolstered by a new executive order providing tariff incentives for new U.S. production. With a strengthened balance sheet and improved cash flow, Century is well-positioned to fund future growth initiatives and consider shareholder returns.

Highlights

5
  • Completed Mt. Holly expansion to full capacity (90 pots) on time and on budget by late June, increasing U.S. primary aluminum production by nearly 10%.

  • Restarted Grundartangi Line 2 by end of July, six months ahead of schedule, returning the plant to near full production.

  • Reported adjusted net income of $257 million ($2.46 per share) and adjusted EBITDA of $327 million for Q2 FY26.

  • Achieved a cash balance of $388 million by quarter-end, with net debt reduced to $98 million, and cash exceeding total debt as of end of July.

  • Secured a significant policy incentive for the Oklahoma project, allowing import of up to 300,000 MT/year at a reduced 25% tariff rate starting 2027.

Concerns

5
  • Experienced some instability at Mt. Holly following the restart, with impacts included in the Q3 outlook.

  • Jamalco refinery continues to see lower quality bauxite from certain mining areas, posing a modest headwind to costs and volumes for another couple of quarters.

  • Anticipates energy headwinds of $10 million to $15 million in Q3 due to warmer summer weather.

  • Expects a small headwind of $5 million in Q3 from moderate increases in other raw material input costs.

  • Forecasts a $20 million to $25 million headwind from realized hedge settlements in Q3, impacting adjusted net income.

Deals & partnerships

Emirates Global Aluminum (EGA) Development of a new primary aluminum smelter in Oklahoma, U.S.

EGA is Century's joint venture partner for the Oklahoma smelter project. The project is progressing with detailed engineering, energy contract negotiations, and financing efforts. Century's share of the tariff benefit from the executive order (300,000 MT/year) will help fund its share of the project.

TeraWulf Sale of Hawesville site and retention of non-dilutive interest in data center $200 million (initial cash proceeds)

Century sold the Hawesville site to TeraWulf in February, retaining a 6.8% interest in the completed data center. TeraWulf has since signed Anthropic as a tenant for a 20-year lease, expected to generate $19 billion in total revenue. Energization is expected in H2 2027, with Century's put option exercisable one year after that.

Anthropic 20-year lease for data center space at Hawesville site $19 billion 20 years (with two 5-year extensions)

Anthropic signed a 20-year lease with TeraWulf, the partner at the Hawesville data center. This contract significantly de-risks the project and enhances the value of Century's retained stake.

Capital programs

Mt. Holly Expansion completed

Benefit:90 pots restarted, plant returned to full capacity, nearly 10% increase in U.S. primary aluminum production, 150 full-time jobs

Q&A highlights

How will the company source metal under the new executive order, and how should investors value the benefit in terms of EBITDA and cash flow?

Century will source metal from various places, including its own resources in Iceland, but will await final rules from Commerce. The benefit can be estimated by taking the reduced tariff rate (25% vs 50%) applied to the LME price, multiplied by Century's 300,000 tons share of new production. This benefit is expected to be material for both EBITDA and cash flow.

“you can just simply take that reduced tariff level. So if we're paying 25% versus the 50% kind of quick rule of thumb, if you just take that, chose your LME. So today, we're at $32.50, apply that, that will give you a sense of the benefit per ton. And then Century should be able to import our share of the new production, which is 300,000 tons and you just multiply those together, and you can see it would be quite material, the benefit, should be the same on both the EBITDA and cash flow side.”

Detailed narrative

Operational Achievements and Capacity Restorations

Century Aluminum successfully completed two major capital projects ahead of schedule, bringing all assets to full capacity for the first time in over a decade. The Mt. Holly expansion, involving 90 pots, was finished in late June, adding nearly 10% to U.S. primary aluminum production.

Concurrently, the Grundartangi Line 2 restart was completed by the end of July, six months early, restoring the plant to near full production. These achievements were executed safely and involved welcoming hundreds of new employees.

Market Conditions and Outlook

The company is operating in a strong market, with LME prices at approximately $3,250 per tonne, U.S. Midwest premium at $1.11 per pound, and European duty-paid premium at $500 per tonne. Demand is robust, driven by power and data infrastructure, commercial aerospace, defense, and reshoring efforts.

Management expects a global aluminum deficit of around 1 million tonnes in 2026, persisting into 2027, leading to historically low inventory levels and a tight market.

Oklahoma Smelter Project and Policy Support

Progress continues on the new Oklahoma smelter project, a joint venture with Emirates Global Aluminum, with detailed engineering underway and negotiations for the final energy contract and financing advancing. The company anticipates FID and groundbreaking by the end of 2026, with first hot metal by the end of 2029.

A new executive order from President Trump provides a significant incentive, allowing approved companies like Century to import primary aluminum at a reduced 25% tariff rate, with Century's share for the Oklahoma project estimated at 300,000 metric tons per year starting in 2027.

Financial Strength and Capital Allocation

Century's balance sheet has significantly strengthened, with a cash balance of $388 million at the end of Q2 FY26 and net debt reduced to $98 million. As of July-end, cash on hand exceeded total debt. The company also received $94 million in 45X tax credits and $19 million in insurance recoveries post-quarter.

This robust financial position, combined with potential monetization of its 6.8% stake in the Hawesville data center (valued at $19 billion over 20 years), provides ample capacity to fund the Oklahoma project and pursue other strategic priorities, including capital returns.

Jamalco and Sebree Performance

At Jamalco, the new TG4 power generation turbine came online in early August, enabling self-generated energy and eliminating expensive grid purchases, expected to yield a $20 per ton benefit. However, the refinery faces a modest headwind from lower quality bauxite, which is expected to take a couple more quarters to resolve.

Sebree continued its strong performance, consistently delivering top-tier operating and financial results, setting a high standard for the portfolio.
