Key Highlights

● Third-quarter results come Thursday after the close, with a call at 5 pm Eastern.

● Earlier guidance called for adjusted EBITDA of $325 million to $345 million.

● Mt. Holly is back at full capacity and the Iceland smelter's second line restarted.

● Cash exceeded total Debt by late July.

Century Aluminum (NASDAQ:CENX) will report third-quarter results on Thursday after the market closes, according to a notice the company issued in late October. A conference call and webcast are scheduled for five in the afternoon Eastern time, with a replay available about two hours after the call ends. The release lands after a second quarter in which the primary aluminum producer posted its strongest results in years.

That earlier report put net sales at about $752 million and adjusted EBITDA attributable to the company at roughly $327 million, and it set a third-quarter adjusted EBITDA range of 320-$5 million to $345 million. The coming release will show whether the company landed inside that range and what it says about the restarts, power costs and the proposed Oklahoma smelter.

It covers the second-quarter record, the guidance drivers, the status of each smelter, Tariff rules, the Data Center connection at a former plant site and the balance sheet. It does not estimate the result and is based on company filings and published coverage.

When does Century Aluminum report and what is on the agenda?

The company said it will distribute the third-quarter release through a wire service on Thursday after the close of trading. The call begins at five in the afternoon Eastern time, and listeners can register on the company website shortly before it starts. An archived version is posted soon after the call ends.

The notice was issued in late October from Chicago and listed a company contact for questions. Management usually opens with prepared remarks on results and market conditions, followed by questions about restart progress, energy costs and project financing.

How strong was the second quarter?

Second-quarter net sales were about $752 million, up roughly $103 million from the first quarter and about 35% above the prior year's second quarter. Net Earnings attributable to the company were about $249 million, or $2.39 per diluted share. The first quarter had included a one-time gain of about $288 million from the sale of the Hawesville site, which is why reported earnings fell sequentially.

Adjusted net earnings were about $257 million, or $2.46 per share, versus about $171 million in the first quarter. Adjusted EBITDA attributable to the company climbed to roughly $327 million from about $231 million. Gross earnings were about $228 million, nearly double the first-quarter level.

What does the guidance range assume?

According to the call transcript, higher lagged aluminum prices and regional premiums were expected to add $5 million to $10 million to adjusted EBITDA in the third quarter compared with the second. Volume and mix, reflecting the first full quarter of the expanded Mt. Holly plant, were expected to add $15 million to $25 million. Energy was seen as a $10 million to $15 million headwind because of seasonally warmer weather, and other raw materials about $5 million.

Below the EBITDA line, the company expected realized hedge settlements of $20 million to $25 million in losses and tax expense of $10 million to $15 million, both of which affect adjusted net earnings. Operating expenses were expected to be flat. These components give readers a way to compare actual results with expectations item by item.

What happened with shipments and prices?

Primary aluminum shipments were about 131,000 tonnes in the second quarter, up about 6% from the first quarter. American shipments were about 95,000 tonnes and Icelandic shipments about 36,000. The company noted that finished goods inventory rose at quarter end because of shipment timing, and said much of it should ship in the third quarter and convert to cash.

Management cited a realized benchmark price near $3,250 per tonne in the second quarter, up about $350 from the first, and a Midwest premium of roughly $2,480 per tonne, up about 280. The European duty-paid premium averaged about $450. These are management figures from the call, and the filing itself describes price movements only in general terms.

Where do the restarts stand?

At Mt. Holly in South Carolina, the final 90 pots were restarted in late June, on time and on budget, bringing the plant back to full capacity. Management said the expansion lifts total American aluminum output by nearly a tenth and created more than 150 full-time jobs. It also acknowledged some instability after the restart, which it expected to resolve in the third quarter.

In Iceland, the second line at the Grundartangi smelter finished restarting at the end of July, around six months ahead of the timetable shared a year earlier. The line is running at slightly reduced amperage until replacement transformers are installed in the fourth quarter. The plant had suffered an equipment failure in the prior autumn, and insurance recoveries of about $40 million were recorded in the second quarter.

What is the story at Jamalco?

Jamalco, the Jamaican alumina refinery in which the company owns a majority stake of 55%, brought a new power turbine online in early August. The unit lets the refinery generate its own electricity and stop drawing from the grid, and it can run in island mode if the grid fails. Management estimated a benefit of roughly $20 per ton, phased in over the rest of the year.

The refinery was restarted after Hurricane Melissa, and the company's share of those costs was about $10.6 million in the first quarter, with none in the second. Management also flagged lower-quality bauxite from some Mining areas as a modest cost and volume headwind, saying a revised mining plan will take a couple more quarters to implement fully.

How do tariffs and the July executive order affect the company?

The company has said that the national-security tariff program on aluminum imports has helped level the field for American smelters. An executive order issued in July allows companies that build or expand domestic primary aluminum capacity to Import an amount equal to that new production at a 25% tariff, rather than 50%.

On the call, management said the Oklahoma project is expected to qualify for up to 750,000 tons a year, split 60 to 40 between its Emirati partner and Century, which would equal up to 300,000 tons for Century starting next year. The Commerce Department has not yet issued implementing rules, and management said it would provide a final assessment afterward. The company does not expect Mt. Holly to qualify because the program covers imports during construction.

What is the Oklahoma smelter plan?

The proposed new smelter is a joint venture with Emirates Global Aluminium. Engineering by Bechtel continues, talks on a final energy contract with the Utility advanced during the quarter, and the company said financing talks progressed, including conversations with government sources. A $500 million grant from the Department of Energy is secured but released dollar for dollar against qualifying spending and subject to project milestones.

Management said it wants the power contract finalized before a final decision, which it still aims to take around the end of this year, with first metal by the end of the decade. Executives acknowledged local pushback and said they are engaging communities about technology and process concerns. Capital allocation priorities were described as maintaining liquidity, funding sustaining capital and then pursuing organic growth such as Oklahoma.

What is the connection to a data center?

The company divested its Hawesville site earlier this year for $200 million in cash and retained a minority non-dilutive interest of about 7% in the completed data center. Its partner, TeraWulf, has signed a long Lease with a technology tenant, and management expects total lease Revenue of about $19 billion over the initial term.

Energization is expected in the second half of next year. The company can require its partner to take back the minority stake starting a year later, and it has no obligation to fund development costs. Management said the stake could be a possible source of funds for its Oklahoma share if needed.

What does the Balance Sheet look like for Century Aluminum?

At the end of June, Liquidity was about $785 million, including roughly $343 million in cash, about $45 million in restricted cash and about $397 million of borrowing availability. Long-term debt was $480 million with no current maturities. After a $94 million tax Credit refund in July and insurance recoveries, the company stated that cash exceeded total debt at the end of that month.

Operating cash flow for the first half was about $236 million, against capital spending of about $134 million. Management expects cash conversion to improve as growth spending winds down and capital shifts toward sustaining projects in the second half. It said payments to owners would follow once other priorities are cleared and asked for patience.

How did the first half compare with last year?

For the first six months, net sales were about $1,400 million, compared with about $1,190 million a year earlier. Adjusted net earnings attributable to the company were about $587 million, against only $67 million in the same span last year, and adjusted EBITDA reached roughly $558 million versus about $152 million.

Primary aluminum shipments were lower, about 253,000 tonnes versus about 344,000, because capacity was curtailed or still ramping in the first half. The comparison shows that stronger prices and premiums, not volume, drove the improvement so far this year, and it explains why the full effect of the restarts is expected to appear only in later quarters.

Why do energy costs matter so much for a smelter?

Electricity is the largest single input in making primary aluminum, so a change in power prices flows directly into margins. The company said power prices were favorable in the second quarter because of improved weather conditions, and the guidance for the third quarter includes a headwind of $10 million to $15 million as warmer weather lifts prices. Power arrangements differ by site, with some linked to market prices and others fixed under long-term contracts.

Iceland and Jamaica add different factors. In Iceland, the smelter benefits from a stable electricity Supply but is exposed to currency swings, and in Jamaica the new turbine is designed to cut the refinery's dependence on the grid. Together these sites give the company a mix of energy exposures that management tries to balance through hedges, some of which were expected to produce settlement losses of $20 million to $25 million in the quarter.

What does the supply and Demand picture look like?

Management described the global aluminum market as in Deficit by about a million tons this year, with deficits continuing into next year and inventories near record lows. It said very little cushion is left anywhere in the system. The company noted that prices had come back to pre-conflict levels after a limited reopening of the Strait of Hormuz, and warned against assuming a quick recovery in Gulf output.

Demand was said to be supported by power and data infrastructure, aerospace, defense and reshoring of Downstream fabrication, with the Manufacturing survey reading for July the strongest since the spring of two years earlier. These are management comments, not independent data. The company also pointed to tight inventories as a reason the market has little room to absorb disruptions, and it cautioned that restarts elsewhere may take time.

Because aluminum is traded globally, outcomes at Gulf smelters, Chinese output limits and European energy costs can all shift prices and premiums within weeks, and the company's lagged pricing formula means that such moves reach its earnings with a delay of roughly a month. For that reason, management guided on the basis of lagged rather than spot prices, and the next release will show how well that approach matched the actual market.

Where does the company fit in its sector?

Century is the largest primary aluminum producer based in the United States by its own account, with smelters in South Carolina, Kentucky and Iceland and an interest in Jamalco. It is a smaller company than the diversified producers and the S&P 500 aluminum names, and its results are more directly tied to the price of aluminum and regional premiums.

That sensitivity is visible in the numbers. A move of a few hundred dollars per tonne in the benchmark price changes quarterly EBITDA by tens of millions of dollars, which is why the lagged price assumptions in the guidance are central to any comparison.

What should readers look for on Thursday for Century Aluminum?

Readers can compare reported adjusted EBITDA with the guided range and check each driver, including volume, premiums, energy costs and hedge settlements. They can also look for updates on the timing of the Oklahoma decision, the energy contract, tariff rules and the transformer installation in Iceland.

Differences between guided and reported figures can arise from price timing, hedge settlements, restart costs and one-time items such as insurance recoveries, so a careful reading of the reconciliation tables in the filing will be needed once the release is public. The company's own wording on liquidity, capital spending and the Oklahoma timetable will also be part of that reading.
