What does it do?
Century Aluminum Company is a maturing business that earns money by smelting alumina into primary aluminum and selling it to industrial customers at prices tied to global benchmarks. The process requires immense amounts of electricity to run electrolytic cells, called pots, which separate oxygen from aluminum oxide. Money flows into the business when customers like Boeing or Ford buy standard grade or specialized aluminum products. The company's profit is the difference between the global market price for aluminum and its own costs for power, labor, and raw alumina. Customers pay a regional premium on top of the base metal price to ensure delivery to their specific locations.
Where does revenue come from?
The vast majority of revenue comes from the sale of primary aluminum produced at its smelters in Kentucky, South Carolina, and Iceland. Century also generates smaller amounts of revenue by selling value-added products like high-purity aluminum and alloyed ingot, which carry higher margins. Geographic revenue is split between the United States, which accounts for about 60 percent of sales, and Iceland, which serves the European market and accounts for the remainder.

Who are its customers?
Century Aluminum Company serves a concentrated group of industrial manufacturers and metal traders, including 130,632 tonnes of aluminum shipped in the most recent quarter alone. Its primary customers are companies in the transportation, construction, and packaging industries that require bulk raw materials for their own manufacturing lines. In the United States, it provides roughly 50 percent of the total domestic primary aluminum supply, making it a critical vendor for the U.S. defense and aerospace sectors. While the company does not disclose individual customer counts, it relies on a handful of major contracts with industrial distributors and global trading firms like Glencore.
What gives it staying power?
Century’s staying power comes from its access to long-term, low-cost power contracts and its heavy integration into the domestic U.S. supply chain. Aluminum smelting is a commodity business, so the winner is usually the one with the lowest electricity bill. Its Iceland plant runs on geothermal and hydroelectric power, which is significantly cheaper and cleaner than coal-based energy.
Where is it headed?
The company is making a massive strategic bet on the Inola smelter in Oklahoma to become the leader in "green" domestic aluminum. Management is leveraging federal grants to build a facility that runs entirely on carbon-free energy, which would allow them to charge a premium for low-carbon metal. If successful, this would make Century the cleanest and most cost-competitive producer in North America.
Century Aluminum is seeing a sharp acceleration in revenue and profitability, with Q2 2026 sales rising nearly 16 percent sequentially to $752 million. This jump was driven by a combination of higher production at the Mt. Holly facility and a recovery in global aluminum prices. The business is currently earning record adjusted profits as it benefits from federal tax credits that were not available in prior years.
The quality of cash generation has improved dramatically, with the company reporting that its cash and available credit now exceed its total debt for the first time in recent history. Free cash flow turned positive in 2025 at $80 million and is accelerating as the company receives one-time tax refunds, including a $94.3 million credit received in July 2026. This allows Century to fund its massive Oklahoma expansion project using its own cash rather than taking on expensive new loans.
The balance sheet is in its strongest position in decades, moving from a net debt position to holding $343 million in cash as of June 2026. Total debt is well-covered by current assets, and the successful sale of the Hawesville facility for $200 million earlier this year provided a significant liquidity cushion. This financial resilience is critical for a company that must weather the boom-and-bust cycles typical of the mining and metals industry.
Century Aluminum has transformed from a leveraged commodity producer into a financially stable industrial company with a net cash balance sheet and rising margins.
Century Aluminum does not currently pay a dividend and has prioritized using its cash to eliminate debt and fund future growth. The company has not paid a dividend in recent years, focusing instead on internal investments like the Mt. Holly expansion. While it does not have an active buyback program that significantly reduced the share count, it spent roughly $86 million on treasury stock in prior years. The share count has remained relatively stable over the last twelve months, ensuring that existing owners have not seen their stake diluted during this period of high profitability. This is a growth-oriented holding where investors should expect returns to come from price appreciation rather than regular cash payments.
The company’s debt-free status is a major milestone, with cash balances now exceeding total debt as of July 2026. This was achieved through a combination of high metal prices, the sale of the Hawesville site, and the collection of $94 million in government tax credits. This gives management the freedom to self-fund the Oklahoma project without diluting shareholders.
Electricity price volatility in the United States remains the single biggest risk to production margins. While the Iceland facility has stable power, the U.S. plants are more exposed to local grid prices which can spike during extreme weather. Management is attempting to mitigate this by negotiating long-term fixed-rate power agreements for its new facilities.
The global aluminum market is approximately $200 billion today and is expected to reach $240 billion by 2028 as electric vehicle and green energy demand grows. Aluminum is a mature industry where price is set on global exchanges, making cost control the only way to win. While the industry grows slowly with GDP, the shift toward "green aluminum" is allowing producers with low-carbon power sources to separate themselves from the rest of the pack. Century Aluminum stands as a critical domestic player, providing half of the primary supply in the United States.
The aluminum industry is a brutally competitive market where producers have zero control over the price of their product. Because aluminum is a standardized commodity, the dynamic is a constant race to have the lowest production costs in the world. Barriers to entry are high due to the massive capital required to build a smelter, but existing global players constantly fight for market share based on power availability.
Alcoa is the most direct threat, operating with a much larger scale and owning its own alumina mines, which protects it from raw material price spikes. Rio Tinto competes by using massive Canadian hydroelectric dams to produce some of the world's cheapest and cleanest metal, which puts pressure on Century’s U.S. plants. Norsk Hydro is attacking the market with a "circular" model, focusing heavily on recycling that requires far less energy than Century’s primary smelting process.
Century Aluminum is currently holding its ground and slowly gaining an edge in the U.S. market as rivals struggle with higher energy costs. The company’s recent capacity expansion at Mt. Holly proves it can still grow production in a difficult environment.
Century Aluminum’s primary source of protection is its cost advantage derived from unique power arrangements and government subsidies. In Iceland, the company has locked in geothermal and hydroelectric power that is immune to the natural gas price swings that affect competitors in Europe and Asia. This low-cost energy profile allows the company to stay profitable even when the global price of aluminum drops to levels that force other smelters to shut down.
The company's recent financial results, including a 16.7% return on invested capital (ROIC), prove that its current cost structure is superior to its historical performance. While aluminum is a commodity, the 22.6% net margin recorded in the last twelve months is significantly higher than a business with no moat should achieve. Lending further protection is the U.S. government's 45X tax credit, which essentially pays the company for every pound of aluminum it produces domestically.
The moat is currently strengthening. The $500 million federal grant for the new Oklahoma plant is a concrete signal that Century is becoming the "national champion" for U.S. aluminum production. This relationship with the federal government creates a barrier to entry that private competitors without such funding cannot easily overcome, ensuring the company’s domestic dominant position for the next decade.

Capital Allocation Track Record
Jesse Gary has led a remarkable operational turnaround, moving the company from a loss-making commodity player to a highly profitable, net-debt-free business in under three years. His management team has shown a clear ability to navigate complex regulatory and energy environments, particularly in securing the $500 million Department of Energy grant for the Oklahoma project. Their decision to exit the Hawesville site and reinvest that capital into the modern Mt. Holly expansion has proven to be exactly the right strategic call, as evidenced by the 16 percent sequential revenue growth last quarter.
The primary governance risk is the high degree of dependence on Jesse Gary’s strategic vision for the "green aluminum" transition. While the company has a capable bench of operational leaders, the multi-year Oklahoma project requires consistent execution across several presidential and regulatory cycles. There is no dual-class control, and the board is largely independent, but the complexity of the ongoing Iceland insurance recovery and the Oklahoma power negotiations means that a sudden change in leadership could delay the company's most important growth milestones.
We expect revenue to grow from $3.4B in FY2026 to $3.5B in FY2031 (~1% CAGR), with EPS growing from $10.07 to $2.05 (~-27% CAGR). Revenue is driven by global aluminum prices and production volumes which are currently at a cyclical peak, and we expect them to stabilize as the company holds its roughly 1% market share. We expect margins to compress from current record highs as energy costs normalize and the extreme price premiums for primary aluminum revert to historical averages. EPS declines despite flat revenue because the exceptional profit margins seen during the current supply shortage are not sustainable over the long term. Operating margin expected to reach ~15% by FY2031.
Oklahoma smelter doubles domestic capacity with carbon-free power. If successfully built, the Inola plant would make Century the dominant provider of low-carbon aluminum to the U.S. automotive and defense sectors.
Section 45X tax credits provide permanent 10% margin boost. The ongoing capture of manufacturing tax credits effectively subsidizes production costs, allowing Century to remain profitable during market downturns.
Higher realized regional premiums due to U.S. supply deficit. As domestic demand outstrips production, Century can charge higher delivery premiums on top of global metal prices.
Failure to secure long-term low-cost power for Oklahoma. The multi-billion dollar Inola project hinges on an affordable power agreement; without it, the plant’s economics would be severely damaged.
Sharp decline in global aluminum prices (LME). As a price taker, a global recession that crashes aluminum prices would erase Century’s current record margins regardless of its efficiency.
Expiration or repeal of federal green energy manufacturing credits. The current profit surge relies heavily on 45X credits; a shift in political administration could put these subsidies at risk.
Below is our estimate of current and future fair value, with detailed reasoning and assumptions. Fair value is a judgment, not a fact, and other analysts will likely land on different numbers. Use it as one data point in your research, and apply your own discretion in any investing decision.
We use a method that values the company based on its cycle-average earnings rather than today’s record profits. Aluminum is a boom-and-bust business, and the company is currently earning nearly ten times its historical average. Relying on these peak numbers to set a permanent price would be a mistake, so we look forward to a year where profits return to a more sustainable level.
The fair value of $54 is the result of adding up all expected cash profits through 2031 and discounting them back to what they are worth today. We took the estimated 2031 profit of $2.05 per share and applied a 10x multiple, which is roughly what investors have paid for this business over the last five years. We then used a 10% annual discount rate to translate that future $21 stock price and the five years of interim cash flows into today's dollars.
Priced on its current cash profits instead, we get a value of $48—very close to our $54 target. This second method uses a 10x multiple on the company's current cash profits (EBITDA), which is the standard way heavy industry is priced. While this method is slightly lower because it doesn't fully capture the future value of the Oklahoma project, the 11% difference between the two gives us more confidence that our main answer is in the right ballpark.
The single biggest risk is failing to lock in a cheap, long-term electricity contract for the new Oklahoma production plant. Since power is the largest cost in making aluminum, a high-priced contract would make the entire $4.6 billion project unprofitable, likely knocking at least $15 off our fair value. Investors should watch for any updates on "long-term power negotiations" in the next two quarterly reports.
Bear case ($35): The company fails to secure a long-term, low-cost power agreement for its planned Oklahoma smelter by late 2026; or Aluminum prices drop below $2,100 per ton while energy costs in Iceland or the U.S. rise sharply.
Bull case ($78): The "45X" federal tax credits result in a larger margin boost than the expected $1.50–$2.00 per share; or Construction begins on the Inola smelter on schedule, signaling a permanent move toward a lower-cost "green" aluminum model.
