Century Aluminum Signals Strong Upswing in Earnings

Century Aluminum Co ((CENX)) has held its Q1 earnings call. Read on for the main highlights of the call.

Century Aluminum’s latest earnings call struck an optimistic tone as management highlighted a sharp upswing in profitability, a cleaner balance sheet and visible growth projects ramping through 2024. Executives acknowledged cost and operational headwinds but framed them as temporary, arguing that rising aluminum prices and a tightening global market put the company in a strong position for the rest of the year.

Adjusted EBITDA Jumps on Pricing and Efficiency

Century reported adjusted EBITDA of $231 million for the first quarter, a sequential increase of $60 million or about 35 percent. Management credited higher London Metal Exchange prices, better regional premiums, tighter cost control and a favorable sales mix for the stronger profitability, positioning the company well as it enters a higher price environment.

Realized Prices and Premiums Provide Major Tailwind

Realized LME prices climbed to about $2,900 per ton, up roughly $285 per ton quarter over quarter, while U.S. Midwest and European premiums rose sharply. The combined uplift from these price and premium gains added an estimated $85 million of benefit versus the prior quarter, underscoring how quickly Century’s earnings power improves when physical aluminum markets tighten.

Cash Strength and Net Debt Below Target

Century ended the quarter with $332 million in cash, including proceeds from the Hawesville transaction, and reduced net debt to $220 million. Management emphasized that net leverage is now comfortably below the company’s $300 million target, giving it additional flexibility to fund growth projects and navigate commodity volatility.

Mt. Holly Expansion Nears Full Ramp

The Mt. Holly expansion remains on schedule, with the first pots energized roughly three weeks ago and a full ramp targeted by the end of June. Once complete, Mt. Holly’s output is expected to reach about 230,000 metric tons, adding over 125 U.S. manufacturing jobs and lifting total domestic primary aluminum production by nearly 10 percent.

Grundartangi Restart Back Online

Century has begun restarting Potline 2 at its Grundartangi smelter in Iceland, with the process kicking off on April 23. Management expects all pots to be restored by the end of July, and the incremental volumes from this restart are already embedded in the company’s second quarter and full year production guidance.

Q2 Outlook Points to Further Earnings Momentum

For the second quarter, the company guided to adjusted EBITDA of $315 million to $335 million based on lagged realized prices and premiums. Executives noted that if current spot prices for aluminum and regional premiums were to carry through future quarters, EBITDA could run closer to a $400 million quarterly pace, implying meaningful upside beyond the formal guidance.

Oklahoma Smelter Project Gains Traction

Century also highlighted progress on its proposed large scale smelter in Oklahoma being developed with Emirates Global Aluminium. The project envisions capacity of about 750,000 metric tons, which would more than double current U.S. primary aluminum production and is expected to benefit from potential federal support as engineering, power and financing talks advance.

Solid Operational Performance Across Smelters

Operationally, the company reported strong first quarter performance across key assets, including Grundartangi, Mt. Holly and Sebree, despite winter power challenges at Sebree. At the Jamalco alumina operation, Century noted continued progress on commissioning the TG4 steam turbine, an important step toward more efficient and stable output.

Tax Credits and Insurance Support Liquidity

Century ended the quarter with $198 million of accrued 45X tax credits receivable and expects to collect roughly $94 million for 2025 in the near term. Insurance recoveries have reached $83 million so far, and an additional $46 million advance in April is helping to bridge timing gaps between claims and cash payments.

Shipments Dip on Iceland Line Outage

First quarter shipments totaled around 123,000 tons, down sequentially due to Line 2 in Iceland being offline for the full period after its idling late last year. Management noted that the full shipment benefit from the Grundartangi restart will not be visible until the third quarter, when volumes should reflect a more normal run rate.

Energy and Raw Material Costs Pressure Margins

Higher energy and raw material costs weighed on results, with winter power price spikes at Sebree and rising fuel oil, coke, pitch and caustic costs. The company expects these factors to create roughly a $10 million sequential headwind into the second quarter, partially offsetting the benefit of higher realized prices.

Operating Expenses Rise with Seasonal and Growth Needs

Operating expenses are projected to increase by $15 million to $20 million in the second quarter due to seasonal summer hiring and training, as well as higher activity at Mt. Holly and Grundartangi. Management signaled that only part of this seasonal cost build will unwind in the third quarter as the workforce and operations adjust to the expanded production base.

Insurance Timing and Iceland Interruption

While insurance has helped cushion the financial impact of prior disruptions, the timing of recoveries has lagged recognized claims by about $38 million in the first quarter. The business interruption losses in Iceland were treated as exceptional items, highlighting how temporary factors can complicate comparisons between adjusted and reported results.

Jamalco Alumina and Bauxite Issues

At Jamalco, the company continues to recover from Hurricane Melissa while managing lower quality bauxite from certain mining zones, which is forcing changes to mine plans. These factors, combined with depressed global alumina prices linked to Middle East disruptions, are expected to create cost and volume headwinds in the near term.

Temporary Production Limits at Grundartangi

Even after the restart, Grundartangi will operate at modestly reduced amperage until new transformers are installed in the fourth quarter, constraining output relative to full capacity. Management stressed that the electrical upgrade is underway and that the site should return to normal production levels once the replacement equipment is commissioned.

Exceptional Items Add Noise to Results

The quarter also included several exceptional items such as unrealized derivative losses, restart expenses at Mt. Holly, gains from the Hawesville transaction and Iceland business interruption costs. Executives reminded investors that market volatility and contractual price lags mean the second quarter will not fully capture the recent rally in spot aluminum and premiums.

Guidance Signals Stronger Second Half Potential

Looking ahead, management expects second quarter adjusted EBITDA to rise to the $315 million to $335 million range on higher realized LME prices and richer regional premiums, even as costs remain elevated. With Mt. Holly nearing its 230,000 ton run rate, Grundartangi’s Line 2 restart progressing and a forecast global aluminum deficit of roughly 1.4 million tons by 2026, Century sees scope for further earnings growth as market fundamentals tighten.

Century Aluminum’s call painted a picture of a company emerging from a complex period with stronger earnings, a healthier balance sheet and multiple growth levers. While energy, raw materials and operational hiccups in Iceland and at Jamalco pose near term challenges, the combination of rising prices, expanding capacity and potential megaprojects like Oklahoma suggests a constructive setup for investors tracking the stock.
