CENX is up 53% in 2026, trades at roughly 5x forward earnings, controls ~60% of all US primary aluminum production, and just guided for $215–$235M in Q1 adjusted EBITDA. That would be its best single quarter ever — and the Iran war’s supply shock hasn’t fully hit prices yet.
This is the kind of setup that’s hard to find: a company that benefits from tariffs, geopolitical disruption, and a decade-long reshoring trend simultaneously. The catch? The stock has already run 291% over two years, and Q1 EBITDA that good is a hard number to repeat.
Here’s the full picture.
What Century Aluminum Actually Does
Century Aluminum (NASDAQ: CENX) is the largest producer of primary aluminum in the United States, accounting for nearly 60% of domestic smelting capacity. “Primary aluminum” means they take bauxite and smelt it from scratch — energy-intensive, capital-heavy, and the reason so much production left the US decades ago when electricity was cheap elsewhere.
CENX runs three main facilities: Grundartangi in Iceland (their largest, benefits from cheap geothermal power), Sebree in Kentucky, and Mt. Holly in South Carolina (currently mid-restart after a $50 million investment). Combined annual capacity: ~770,000 tonnes. In FY2025, they shipped about 638,000 tonnes.
Revenue for FY2025 came in at $2.53 billion. Q4 net sales hit $633.7 million, up slightly year-over-year, though it missed analyst estimates of $658 million. Gross profit jumped 35.7% to $90 million as realized prices improved. The GAAP headline — net income of just $1.8 million, EPS of $0.02 versus the $1.32 consensus — scared some people. But that was driven by non-cash impairment charges. The underlying business was fine.
More importantly, guidance for Q1 2026 pointed to adjusted EBITDA of $215–$235 million. That’s more than the company earned in adjusted EBITDA for all of 2024.
The Three Tailwinds Stacking Up Right Now
1. Tariffs Doubled the Midwest Premium
In 2025, the US hiked aluminum import tariffs to 50%. The Midwest premium — the surcharge buyers pay above the London Metal Exchange benchmark for domestic delivery — more than doubled. That’s a direct windfall for CENX: they produce here, they sell here, they capture the full premium.
About 85% of US industrial aluminum demand is currently met by imports. Every dollar of tariff-driven premium that pushes up the domestic market price flows to CENX’s realized prices without a corresponding increase in their production costs (which are largely fixed).
2. Iran Strikes Hit the Gulf’s Biggest Smelters
Last month, Iranian drone and missile strikes hit two major Persian Gulf aluminum facilities. The two plants combined produce 3.2 million tonnes of aluminum per year. On the first day of trading after the strikes were confirmed, LME aluminum futures surged 6%. Bloomberg called it “one of the biggest supply shocks in the history of the aluminum market.”
The Middle East accounts for roughly 9% of global aluminum production, but the disruption is amplified because inventories had already been depleted. As of April 2, 2026, LME aluminum is trading around $3,482 per tonne — up roughly 10% from pre-war levels even as copper and other base metals have softened.
Even before the strikes, the Strait of Hormuz closure had cut off key alumina inputs to Gulf smelters. The cascade of production cuts is still in progress, and disruption could persist into Q3 2026 even if the Strait reopens. None of this hurts CENX — their Grundartangi plant runs on Icelandic geothermal power and their US plants aren’t dependent on Middle Eastern supply chains. They’re a pure beneficiary.
3. The Oklahoma Mega-Smelter Changes CENX’s Story Entirely
On January 26, 2026, Century Aluminum announced a joint development agreement with Emirates Global Aluminium (EGA) to build the first new primary aluminum smelter in the United States since 1980. The site: Inola, Oklahoma. CENX owns 40%; EGA owns 60%.
The planned capacity: 750,000 tonnes per year. Current total US primary aluminum production is around 800,000 tonnes annually — this plant would more than double it. Bechtel was selected in February to lead engineering. Construction is targeted to begin by end of 2026, with first production before 2030.
Total project investment: approximately $4 billion. CENX’s 40% share is ~$1.6 billion, likely funded through equity, project debt, and federal support (Energy Secretary Chris Wright met with EGA and CENX leadership in February specifically to discuss this project). The Oklahoma smelter is 3–4 years from production, so it contributes nothing to near-term earnings. But it repositions CENX from “operator of legacy smelters” to “builder of the US aluminum industrial base.” That narrative shift alone is worth something.
Financials: Liquidity Is Solid, Forward Estimates Rising Fast
As of December 31, 2025, CENX held $134.2 million in cash and $283.8 million in available borrowing capacity — $418 million total liquidity. They reduced net debt by $54 million during Q4 alone.
Analyst consensus estimates for 2026 EPS have increased 42.1% over the past 60 days. The stock currently trades at ~5.47x forward adjusted earnings — a meaningful discount to the metals processing industry average. Analyst price targets range from $62 to $66. At $63.51, the stock is right at the bottom of that band.
Bull Case
The bull case runs on overlapping catalysts — you don’t need all three to work:
Scenario A — Sustained High Prices: LME aluminum holds above $3,400/tonne through Q2, the Midwest premium stays elevated, and Q1 EBITDA prints at $225M or higher. The market re-rates toward 8–10x earnings. At 8x, $63.51 is the floor.
Scenario B — Oklahoma FID: A Final Investment Decision on the Inola project — expected later in 2026 — would be a major catalyst. The market hasn’t priced in the capacity expansion. When it does, the stock’s narrative changes completely.
Scenario C — Structural Reshoring: 50% tariffs and the critical minerals designation of aluminum look durable regardless of political cycles. The production math for domestic smelters keeps improving.
Bear Case
Q4 Was Already a Miss: Revenue came in $24 million below expectations. That’s not a non-cash issue — demand was softer than forecast.
10-K Delay: On March 3, CENX disclosed it couldn’t file its annual 10-K on time, citing increased complexity from the Oklahoma JV. These delays often turn out to be nothing. But “we’re building our first new smelter in 45 years” is exactly the kind of complexity that can surface accounting surprises. Yellow flag.
Iran War Can End: The supply shock driving aluminum prices higher could reverse quickly. A ceasefire, Strait reopening, and Gulf production resuming would compress the Midwest premium and push LME prices back toward $2,800–$3,000/tonne. CENX’s margins compress significantly in that scenario.
The Stock Has Run Hard: Up 291% over two years. If Q1 EBITDA comes in at the low end or Q2 guidance disappoints, the stock could give back 20%+ fast. High-conviction momentum stocks punish misses.
Energy Costs Are a Silent Risk: Aluminum smelting is one of the most energy-intensive industries in existence. Electricity costs at the US plants are materially higher than at Grundartangi. If the Iran war keeps energy prices elevated, that starts biting into the production economics it’s simultaneously improving on the sales side.
The Verdict
CENX is a legitimate play on three things at once: tariff protection, geopolitical aluminum supply disruption, and US industrial reshoring. The Q1 EBITDA guidance of $215–$235M, if real, would be the company’s best quarter ever. At 5.47x forward earnings, the stock is still cheap relative to that earnings power.
The Oklahoma smelter isn’t generating revenue yet, but it changes the story completely: CENX goes from a company managing aging US smelters to the company building America’s aluminum future. That’s a different stock.
The honest entry question is whether you’re early enough. If you’re buying now, you’re betting on sustained Iran-driven supply disruption continuing into Q2–Q3 and tariffs holding at 50%. Both are reasonable given current macro. Neither is guaranteed.
Compelling at $55, fair at current levels (~$63), expensive above $75 unless the Oklahoma FID lands with significant federal financing attached.
