Thesis Summary

Century Aluminum (CENX) is transitioning from a cyclical survivor to a core beneficiary of global energy transition trends and supportive U.S. trade policies. The company is capitalizing on record-high Midwest premiums driven by increased tariffs on imported aluminum, while expanding production at its Mt. Holly and Grundartangi smelters. Furthermore, its joint development agreement with Emirates Global Aluminium to build a greenfield smelter in Oklahoma represents a transformative long-term growth catalyst.

Scenarios · 12-month scenario targetsAnchored at research date

Bear CaseDownside scenario

$60.00

Geopolitical resolutions in the Middle East lead to a rapid destocking and a drop in aluminum prices below $2,800/metric ton. High energy costs or localized power grid disruptions squeeze smelting margins, and the Oklahoma project faces delays in securing power or financing.

Base CaseCentral scenario

$70.50

Matches the consensus mean

Aluminum prices stabilize around S&P's updated assumption of $3,300/metric ton for 2026 and $3,000 for 2027. Mt. Holly successfully completes its potline expansion and Grundartangi reaches full capacity by late summer 2026. Leverage continues to decline below 2.0x debt-to-EBITDA.

Bull CaseUpside scenario

$83.00

LME aluminum prices remain elevated above $3,300/metric ton and the Midwest premium stays near record highs. The Oklahoma greenfield project secures highly favorable power contracts and breaks ground on schedule, while Mt. Holly and Grundartangi expansions run at maximum efficiency, driving record free cash flow.

Scenarios are anchored to street consensus at the research date, with our probabilities and rationale.

Key Investment Merits

Strong margin expansion driven by record-high U.S. Midwest premiums and supportive trade policies.
Immediate volume growth from the restart of idled capacity at Mt. Holly and the rapid recovery of Grundartangi.
Transformative long-term upside from the Oklahoma greenfield smelter project, backed by a $500 million DOE grant.
Significantly improved balance sheet with debt-to-EBITDA declining to 2.6x at the end of 2025 and further deleveraging expected.

Key Investment Risks

High sensitivity to volatile LME aluminum prices and regional premiums.
Exposure to energy price volatility and potential power grid curtailments.
Operational single-point-of-failure risks, as demonstrated by the historical transformer failure in Iceland.
Execution risks associated with large-scale capital projects like the Oklahoma smelter.

Thesis Invalidation Triggers

A sharp decline in LME aluminum prices below $2,500/metric ton.
Inability to secure a viable power agreement for the Oklahoma project, leading to its cancellation.
Severe power supply disruptions or cost spikes at the Kentucky or South Carolina smelting operations.
