Solvency

Interest expense is not separately reported in the latest filings, so interest coverage cannot be computed.

Bullet Takeaways

• A 50% tariff on certain primary aluminum imports has left Century's American and Icelandic plants selling into those markets duty-free, a position the annual filing describes as an advantage "over our competitors who sell into these markets under these tariff regimes".

• The profit stream behind today's price is a cycle-peak stream: normalized across five years with one-time charges added back, operating income runs near 160 million dollars against the 490.8 million dollars booked over the trailing year.

• The next checkpoint is the Inola, Oklahoma smelter, where construction is expected to begin by the end of 2026 and still depends on a long-term power agreement, a definitive joint venture with EGA, and 500 million dollars of Department of Energy funding the company describes as subject to negotiation.

Bull Case

The market is paying close to ten dollars for every dollar of operating profit this business earned over the past year, and folded into that price is a demand for roughly 27% annual growth in operating profit held for five years. For a commodity smelter that reads as absurd until you look at what changed underneath it. Washington now applies a 50% tariff to certain primary aluminum imports, and Century's plants sit inside the wall. The 10-K puts it without decoration: "Our U.S. and Icelandic businesses currently access these respective markets duty-free which provides us with an advantage over our competitors who sell into these markets under these tariff regimes." A tariff does not raise the world price of aluminum. It raises the price paid inside the protected market, and a producer already inside collects that gap without building anything to get there.

Smelting is the business of turning electricity into metal, so the power contract is the business. Sebree runs on a market-based electrical power agreement, and the filing describes the fleet more broadly as running on "market-based power contracts that have historically provided electricity to these operations at competitive prices". On the input side the hedge is structural rather than financial: the company buys "certain of our alumina requirements under supply contracts with prices tied to the same indices as our aluminum sales contracts". When metal falls, that cost falls with it. What remains exposed is power and the handful of costs that do not track the exchange, which is exactly the ground the bear case works on.

Owning the alumina goes further than contracting for it. Century took 55% of Jamalco in May 2023, and the Jamaican operation is not a passive stake: 391 holes were drilled across the bauxite pits during 2025, producing 2,748 assays for the resource work. The reporting was recast in the March 2026 quarter to match how the company is actually run, concluding that "the Company has determined that it has only one operating and only one reportable segment, and that segment is managed on a consolidated basis". Aluminum is about 89% of revenue and alumina the remainder, but they are one machine. The value of holding the refinery is that when alumina spikes, the profit shows up on the other side of the same ledger instead of walking out the door to a supplier.

The Hawesville trade is the clearest read available on how management treats assets that have stopped earning. On February 2, 2026 Century "completed the sale of our Hawesville, Kentucky facility to an affiliate of Terawulf, Inc." for 200 million dollars plus a 6.8% non-dilutive interest in the buyer and a put option that comes alive once the site delivers at least 375 MW of critical IT load to data center customers. An idle Kentucky smelter became 200 million dollars, an interest and option carried together at 97.0 million dollars, and a claim on data center buildout. Note who is on each side of that: shareholders received the proceeds of a plant that was producing nothing, and the buyer received a site already wired for very large industrial load. Both sides got the thing they valued more.

Then there is Oklahoma. "The new plant, to be built in Inola, Oklahoma, is expected to produce 750,000 tonnes of aluminum per year, more than doubling current U.S. production." That is the company's own filed description of a project it intends to build and operate with EGA, with construction expected to start by the end of 2026. A domestic producer adding capacity of that scale, inside a tariff wall, with federal money attached, is underwriting something different from a bet on the metal price. It is a bet that American primary aluminum production is a policy priority for long enough to build a plant.

Against the wider metals cohort the current margin sits at the top. KALU earned a 6.6% operating margin on 3.70 billion dollars of revenue; ATI managed 14.3%; WS came in at 4.2%. Century's trailing operating margin is 19.3%. Those companies convert and fabricate while Century smelts, so the spread describes position on the chain rather than management skill. That is still the point. When the metal price and the tariff are both working, smelting is where the money lands first.

Bear Case

The balance sheet looks harmless, and that is the trap. Gross borrowings of 545.9 million dollars against 244.1 million dollars of liquid assets leave net debt near 301.8 million dollars, or 0.61 times operating profit, which is nothing at all for an industrial company. The problem is the denominator. Take the cycle out of it and the picture changes: normalized across five years with one-time charges added back, operating income runs near 160 million dollars, roughly a third of the trailing figure. The same borrowings measured against that number are not comfortable, and the London Metal Exchange, not management, decides which of the two figures describes next year.

Cash generation tells a harsher story than profit does. Free cash flow over the trailing year was about 27.3 million dollars, set against operating income of 490.8 million dollars. Aluminum plants absorb capital continuously: pots need relining, working capital swells with the metal price, and a 750,000-tonne project sits in front of them. A business converting that small a share of its operating profit into free cash has less room than a leverage ratio suggests, and that is before the first shovel goes into Oklahoma ground.

The credit line is sized for calm weather. At the end of 2025 the US revolving facility carried a 250 million dollar maximum with 205.3 million dollars of borrowing availability, and it contains "a springing financial covenant that requires us to maintain a fixed charge coverage ratio of at least 1.0 to 1.0 any time availability under the U.S. revolving credit facility is less than or equal to $25.0 million". A covenant shaped that way only engages after liquidity has already thinned, which is precisely the moment a smelter buying power at market prices is losing money on every tonne it ships. The structure is not fragile today. It is fragile in the state of the world where the rest of this section is right.

That state of the world has a specific mechanic behind it, and the filing states it flatly: "Because we sell our products based on published market prices, we are not able to pass on to our customers any increased cost of raw materials that are not linked to such prices." Revenue is set by an exchange. A meaningful slice of the cost base is not. Iceland supplies a second version of the same exposure, where output depends on hydrology rather than demand, and the filing notes that "The end of these curtailments remain subject to weather patterns and reservoir levels in Iceland and other factors." Policy is the third: the company's ability to collect Section 45X production credits is listed among its risk factors, with the warning that "expiration of the IRA may materially adversely affect the Company's future operating results and liquidity".

All of which returns to what the price requires. Roughly 27% annual growth in operating profit, sustained five years, is the assumption inside today's quote. Among comparable fast-growers that reached that pace, closer to three in ten were still delivering it half a decade later, and Century controls neither the metal price nor the tariff schedule that would put it in the majority. If the requirement fades, the multiple does not hold. The earnings-power methods, which capitalize normalized profit and assume no growth whatsoever, land far under today's quote, and that is the neighborhood a market that stops crediting the growth would be pricing toward.

One more item sits inside the trailing figures. The gain of 287.9 million dollars recognized on the February transaction was a genuinely good trade, and it happened once. Trailing net income of 349.6 million dollars flatters the run rate accordingly. Meanwhile the share count has drifted up about 1.9% a year over the four years to March 2026, so each share owns slightly less of the company than it did, which is the opposite of what a peak-earnings year is supposed to fund.

Valuation

Today's price embeds a demand. For the quote of $46.22 to make arithmetic sense, operating profit has to compound at roughly 27% a year for five years, and that is a whole-company demand rather than one product line carrying the load. The rate itself is not foreign here; the company has run at that pace recently. The stretch is duration. Of comparable fast-growers that reached it, about 31% were still there five years later. The requirement is also sensitive to the discount assumption sitting behind it, so it is best held as approximate rather than precise.

The methods used to triangulate the business split cleanly, and the split is the information. Asset-based approaches, working from book value near 11.00 dollars a share and the unusually high return the company earned on that book over the trailing year, land within reach: the price sits about 19% above where that family centers. Peer multiples land closer still, with the price roughly 6% above that family. Earnings power is where it breaks, and the price exceeds that family by about 4.7 times. The reason is visible in how one of those methods is built. It averages operating profit over five years, adds back one-time charges, taxes the result, and capitalizes it with no growth assumed at all. That method is not being pessimistic. It is asking what the business earns across a cycle rather than at the top of one, and for a smelter the difference between those two questions is the whole report.

Read together, that is a value read with a cyclical asterisk, not a growth bet. Book value and current-multiple math both defend the price; through-cycle earnings power does not come close. A buyer at today's level is underwriting a specific proposition: that the trailing year sits nearer to normal than the five-year average does, because the tariff structure and the domestic supply position have moved the whole earnings base up rather than merely produced one good year.

The cash line qualifies that further. Free cash flow of about 27.3 million dollars over the trailing year sits behind operating income of 490.8 million dollars, and one method in the set does nothing more than capitalize that free cash flow at a required return, which is why it lands so far below everything else. Neither figure is wrong. They measure different things at different points in a capital cycle, and a year heavy on relining and inventory build will produce exactly that gap. The balance sheet is not the binding constraint against any of it: net debt near 301.8 million dollars, 0.61 times operating profit, 244.1 million dollars of liquid assets, and no cash burn. The company also pushed its maturity wall out during the year, redeeming the 2028 notes into a 2032 issue and booking a 6.2 million dollar loss on the early extinguishment.

Cohort position sharpens the picture without settling it. KALU runs a 6.6% operating margin, ATI 14.3%, CRS 21.3%, and Century's trailing 19.3% sits near the top of that range while the business itself sits at a different point on the chain, closer to the raw metal. AA, the nearest domestic comparison at 12.66 billion dollars of revenue and an 8.2% profit margin, grew revenue essentially flat over the year. The message from the cohort is not that Century is better run than its neighbors. It is that smelting is where the operating leverage lives, and operating leverage is a two-way instrument.

Catalysts

The February transaction is already in the numbers and not yet fully in the story. On February 2, 2026 Century closed the sale of the Hawesville, Kentucky plant to an affiliate of Terawulf, taking 200 million dollars plus a 6.8% non-dilutive interest in the buyer and a put option tied to the site delivering at least 375 MW of critical IT load to data center customers; the interest and the option were carried together at 97.0 million dollars at closing, and the company recognized a gain of 287.9 million dollars. The put option is the piece worth tracking. It converts a stranded smelter site into a claim on data center construction rather than on the metal price, and it pays off on a milestone that is measured in megawatts.

Oklahoma is the larger event. The company intends to build a plant at Inola with EGA expected to produce 750,000 tonnes a year, with construction expected to start by the end of 2026, subject to completion of detailed engineering, a competitive long-term power supply agreement with Public Service Company of Oklahoma, and a definitive joint venture agreement. The federal piece, 500 million dollars from the Department of Energy, is described as "subject to review and will be subject to negotiation of specific terms and contingent on our compliance with the requirements negotiated with the DOE". Each of those three conditions resolves one way or the other over the coming quarters, and the power agreement is the one that sets the project's position on the cost curve for its entire life.

Two policy variables sit above everything management does. The 50% tariff on certain primary aluminum imports is what currently separates the price Century realizes from the world price, and the Section 45X production credits under the Inflation Reduction Act are a direct subsidy on domestic output that the company itself flags as uncertain in its risk factors. Neither is a company decision. Both move the earnings base further in a quarter than any operational change available to management could move it in a year.
