To The Moon

I am acutely aware that pitching an aluminium producer at a tech-stock multiple sounds like a violation of several unwritten investing laws. Aluminium is supposed to be dull, cyclical, and cheap—something you hedge, not something you underwrite with conviction. Yet $Century Aluminum(CENX)$ has forced me into an awkward position: defending a 60× P/E smelter as a rational way to play US reshoring, industrial policy, and ESG-driven scarcity. If nothing else, this is proof that the market has entered a strange new phase of adulthood.

Aluminium reshaped by innovation, policy, and ESG imperatives

This is not a value story. It is not even really a commodity story. It is a policy-enabled growth trade disguised as heavy industry, and the sooner investors accept that framing, the sooner Century’s valuation starts to make sense.

Where Aluminium Gets Inevitable

The gravitational centre of the Century thesis is its roughly 40% stake in the planned Inola smelter in Oklahoma. Everything else—Mt. Holly, Iceland, legacy assets—exists to buy time. Inola is the future the market is paying for.

This is not incremental capacity. It is a purpose-built, next-generation smelter designed around modern potlines, low-carbon power, and domestic offtake. By 2026, aerospace and automotive manufacturers will not be gently nudging suppliers toward lower carbon intensity. They will be enforcing it contractually, backed by disclosure rules, supply-chain reporting requirements, and internal procurement mandates that leave little room for negotiation.

The key insight investors often miss is that the ‘green aluminium premium’ is not primarily about charging more per tonne. It is about staying in the room. In aerospace and EV supply chains, the premium may be somewhere between 5% and 10%, but the real economic lever is exclusion risk. If you cannot certify carbon intensity and domestic provenance, you are not haggling over price—you are simply disqualified. Inola is being built explicitly for that regime. There is nothing accidental about this inevitability.

Growth in Value’s Clothing

On conventional metrics, Century looks indefensible. A market capitalisation just over $5 billion, enterprise value around $5.5 billion, and trailing EBITDA of roughly $250 million imply an EV/EBITDA multiple in the low-20s using headline numbers. The company itself screens closer to the high-20s once you adjust for downtime and normalised run-rates. Either way, this is not cheap.

Margins underline the discomfort. Operating margins sit just above 9%, net margins barely clear 3%, and free cash flow remains thin. This is not a business minting cash today.

But the market is not capitalising today’s earnings stream. It is capitalising protection. US aluminium tariffs and trade barriers have quietly become one of the most powerful industrial subsidies in the market, lifting the effective clearing price for domestic producers well above what global supply-demand dynamics alone would justify. Call it protectionism, call it national security, or call it industrial policy in a hard hat—the effect is the same.

Viewed through that lens, Century is not expensive for what it is; it is expensive for what it used to be. The elevated beta reflects this reality. Investors are trading execution and policy durability, not spot aluminium.

A Financial Base That Explains the Anxiety

That future promise, however, still rests on today’s messy financials.

Century’s trailing twelve-month revenue of roughly $2.5 billion and EBITDA around $253 million place it in an awkward middle ground. Margins are meaningfully below Norsk Hydro’s low-teens profile but materially stronger than what ageing US smelting assets historically delivered. This is a business mid-transition, not yet optimised but no longer structurally broken.

The balance sheet is where the nerves live. Total debt of about $620 million equates to roughly 2.5× EBITDA—uncomfortable, but not reckless given tariff protection and locked-in power costs. Liquidity is adequate, with a current ratio north of 1.7, but there is no margin for serial mistakes.

One underappreciated stabiliser is ownership structure. Nearly 40% insider ownership is unusually high for a company of this size. That concentration magnifies both upside and downside, but it also means management’s incentives are brutally aligned. There is no hiding behind adjusted numbers here.

When Execution Fails, the Bill Arrives Immediately

The transformer failure at the Grundartangi smelter in Iceland is the clearest illustration of Century’s execution risk. This was not cosmetic. Grundartangi represents roughly a fifth of Century’s aluminium capacity and, in a normal year, contributes on the order of 20% of consolidated EBITDA. When it goes offline, the income statement feels it immediately.

Insurance will cover much of the physical damage, but it does not eliminate the timing mismatch. Cash flow takes the hit first; reimbursement follows later. In a business with thin margins and meaningful leverage, that gap matters. Aluminium smelting is unforgiving in this way. Single-point failures can erase quarters of earnings in an afternoon, and there is no graceful workaround.

Rather than downplaying this episode, I see it as central to the thesis. Legacy assets are fragile. New capacity is not just greener; it is more reliable. The market will forgive disruptions if it believes they are transitional. It will not forgive a pattern. This is why Mt. Holly’s return to full capacity by mid-2026 is so critical. It is the financial bridge that allows Century to get from today’s volatility to Inola’s promise.

Why the Giants Don’t Get the Same Multiple

Century’s appeal only becomes obvious in contrast. $Alcoa(AA)$ remains the most obvious comparator, but its earnings are still heavily exposed to international aluminium pricing, with a majority of revenue generated outside the US. That global footprint dilutes the direct benefit of US trade protection in a way Century’s increasingly domestic focus does not.

$Rio Tinto PLC(RIO)$ owns world-class aluminium assets, but aluminium competes internally with iron ore and copper for capital. Policy tailwinds do not get ring-fenced; they get blended into a diversified mining complex.

Norsk Hydro sets the standard for low-carbon aluminium, but its economics are inseparable from European energy politics. Clean power is an advantage—until it becomes a geopolitical vulnerability.

Century’s edge is not operational supremacy. It is strategic purity. It is one of the few public names where US aluminium self-sufficiency is not an ancillary narrative but the entire investment case.

How and When This Gets Re-Rated

The market is not waiting for a single announcement; it is watching a sequence. Inola’s permitting and construction milestones will matter more than quarterly earnings noise. Mt. Holly’s stabilisation is the near-term test of balance-sheet resilience. Any formal tightening or extension of US trade protections would act as an accelerant, while the first long-term offtake agreements explicitly tied to low-carbon domestic aluminium would likely force a repricing.

The asymmetry resolves over the next eighteen to twenty-four months. Execution compresses the multiple by lifting earnings power. Failure does the opposite, quickly and without sentimentality.

A Verdict Without a Safety Net

$Century Aluminum(CENX)$ is not a safe stock. It is volatile, capital-intensive, and exposed to both politics and execution risk. But it is also one of the cleanest expressions I can find of a simple view: the US is serious about reshoring heavy industry, and it is willing to subsidise the outcome through trade policy.

If Inola delivers and Mt. Holly normalises, today’s valuation will not look reckless—it will look early. If management stumbles, the downside will be sharp and unapologetic. That is the deal.

I am comfortable with that bargain. This is not for defensive portfolios or investors who flinch at volatility. But as a high-conviction bet on where industrial policy, ESG mandates, and domestic manufacturing collide, Century Aluminium is far more compelling than a 60× P/E aluminium stock has any right to be.
