Setup Analysis:

2. Thesis Layer

• Primary Secular Thesis: Reshoring & Industrial Automation (Materials & Inputs) — Tier Direct, Confidence High.
• Century Aluminum is a primary beneficiary of the U.S. drive to restore domestic primary aluminum production, specifically for defense and critical infrastructure. The company's role is direct: it is executing the physical expansion of U.S. smelting capacity to replace imports and supply military-grade requirements.
• Secondary Secular Themes:
• Critical Minerals & Materials (Specialty & Advanced Materials): Tier Direct, Confidence Moderate. The company is restoring production of military-grade high-purity aluminum.
• Energy Transition & Electrification (Electrification Materials): Tier Second Order, Confidence Moderate. Demand is driven by lightweighting and power infrastructure build-out.

Conviction Weighting: The convergence of these three themes creates a robust secular tailwind. The "Reshoring" thesis is the dominant driver, supported by the specific narrative of "rearmament manufacturing" and "defense" mentioned in the evidence. The fact that the company is simultaneously addressing supply disruptions in the Gulf (via E8) and expanding domestic capacity (via E1, E2, E6) positions CENX as a structural solution to a multi-regional supply deficit. The direct tier exposure to Reshoring carries the highest conviction weight, as it aligns with government policy and industrial necessity rather than just cyclical demand.

3. Business Overview

Century Aluminum Company is a producer of primary aluminum and owns a 55% interest in a bauxite mining and alumina refinery joint venture (E9). The company operates smelters in the United States (Mt. Holly, Indiana) and Iceland (Grundartangi), and manages a carbon anode facility in the Netherlands (E24).

Operational Status as of June 13, 2026:

• Mt. Holly Expansion: The company is in the final stages of a major expansion. Management stated on May 7, 2026, that the first pots at Mt. Holly started 3 weeks prior (early May) and the project is "on schedule to bring the full expansion project online by the end of June" (E1). This expansion will increase Mt. Holly's total production to approximately 230,000 metric tons (E2).
• Grundartangi Restart: The restart of Line 2 at the Grundartangi facility began on April 23, 2026, and is on schedule to restore all pots by the end of July (E4).
• Full Capacity Milestone: Management expects that by the end of July 2026, "for the first time in over a decade, all Century assets should be operating at full production capacity" (E5).
• Strategic Asset Sale: On February 2, 2026, the company sold a facility to an affiliate of Terawulf, Inc. for $200.0 million in cash and a 6.8% non-dilutive minority equity interest in Raylan Data Holdings LLC (E13).
• Hedging & Pricing: As of March 31, 2026, the company had significant open positions to fix forward prices: 59,500 tonnes of LME aluminum and 99,400 tonnes of MWP aluminum, settling through December 2027 (E10, E11). Additionally, the company holds 957,552 MWh of Indiana Hub power price swaps through December 2027 (E14).
• Customer Concentration: Approximately 54.0% of consolidated sales in 2025 were derived from Glencore plc and its affiliates (E18).

4. Archetype and Conviction

• Archetype: Cyclical Recovery (Margin Inflector).
• The company is transitioning from a period of curtailed capacity and operational restarts to a phase of full utilization and expanded output. The "margin inflector" aspect is driven by the completion of the Mt. Holly expansion and the full restart of Grundartangi, which management expects to "increase Mt. Holly's profitability significantly" (E3).
• Valuation Context:
• Forward consensus EPS for FY1 (2026) is estimated at $11.42, and FY2 (2027) at $13.83 (E25).
• The company expects the Mt. Holly project to "fully repay its capital cost by the end of 2026" (E3), suggesting a rapid return on invested capital and a potential shift in the capital structure.
• Conviction Stack:
• Thesis Strength: High. The alignment with U.S. defense and industrial reshoring is structural and policy-backed.
• Evidence Quality: High. Multiple primary sources (earnings transcripts, SEC filings) from May and March 2026 confirm specific operational milestones and financial hedging.
• Structural Quality: Strong. The company is moving from a "curtailed" state to "full capacity" with a new 750,000-tonne plant (E6, E19) that will double U.S. production.
• Rerating Potential: Significant. The combination of full capacity utilization, hedged forward prices through 2027, and the strategic sale of the data center site provides a clear path to margin expansion.

5. Invalidations, Strengtheners, and Gaps

• Invalidation Triggers:
• Failure to meet the "end of June" full production target at Mt. Holly or the "end of July" full restart at Grundartangi would contradict management's guidance and weaken the cyclical recovery thesis.
• A significant disruption in the Strait of Hormuz or a resolution of the Gulf supply issues that drastically lowers global aluminum prices (though the company is hedged, this impacts the spot price component of revenue).
• Strengtheners:
• Confirmation that the Mt. Holly expansion is fully online by the end of June 2026 as stated.
• Further evidence of demand acceleration in the defense or data center sectors (leveraging the Terawulf partnership).
• Extension of the hedging program beyond December 2027 at favorable rates.
• Evidence Gaps:
• Specific Q2 2026 Financials: While the March 31, 2026, filing provides data, specific Q2 2026 earnings results or updated guidance on the *actual* realized margins post-expansion are not yet in the evidence base (as the date is June 13, 2026, and Q2 results are typically released in July).
• Power Supply Agreement: The evidence notes that construction of the new Oklahoma plant is subject to completing negotiations with Public Service Company of Oklahoma (E17). The status of these negotiations as of June 13 is not explicitly detailed in the provided evidence, though the Mt. Holly expansion is the immediate focus.

PRIVATE ANALYST CALL

Judgment: Buy Confidence: high Key evidence: Management confirmed Mt. Holly expansion is on schedule for full online status by end of June 2026; All assets expected to reach full production capacity by end of July 2026; Company has secured significant forward price hedges for aluminum and power through December 2027. Key risks: Failure to meet the end-of-June production timeline at Mt. Holly; Potential delays in power supply negotiations for the new Oklahoma facility; High volatility (7.7% ATR) may trigger stop-losses before a sustained breakout occurs. Expected path: Management expects the Mt. Holly expansion to fully repay capital costs by end of 2026, driving a significant margin inflection as the company transitions to full capacity utilization across all global assets. Expected horizon: 6 to 12 months for the full thesis to play out as capacity ramps and hedged contracts settle.
