Key catalyst

Q3 results test the full-capacity run rate • 2026-12-30

Base target: $39 / p=45% prob

Biggest risk

Q2 benefited from favorable realized metal prices and power conditions, while raw-material costs were unfavorable. The Inola moratorium and litigation put the original construction timetable in doubt. A reversal in metal premiums, cost inflation, operational setbacks, or prolonged project delay could overwhelm restart benefits. [#SEC-8K-2026-08-06] Company results; Oklahoma attorney general; KOSU report.

Invalidation

Break below $27 or thesis failure.

What would change my mind?

Q2 sequential sales and adjusted EBITDA gains, completed capacity restarts, and Q3 guidance support the packet's positive directional prior. If the higher run rate persists and the Oklahoma project's legal and power hurdles clear, earnings and project optionality could support upside. [#SEC-8K-2026-08-06] Company results.

Commentary

The supplied news list is mostly from August, outside the latest 30-day window, so its tone is not a reliable current sentiment measure. No supported social, options, short-interest, or employee measures were supplied; the zero fields above denote unavailable data, not measured neutral readings. The packet does not establish a post-release price reaction or verified analyst revisions. Strong operating evidence is offset by the newer Oklahoma timetable risk.

Q3 results test the full-capacity run rate
Century reported Q2 shipments of 130,632 tonnes, adjusted EBITDA of $326.9 million, and Q3 adjusted EBITDA guidance of $325 million–$345 million. The next results will test whether the Mt. Holly restart and Grundartangi recovery sustain shipments and margins despite raw-material and power-cost exposure. [#8-K-2026-08-06] [#SEC-8K-2026-08-06] Company results.

Oklahoma smelter approval and investment decision
Century announced a 40% stake in a proposed 750,000-tonne-per-year Inola smelter and originally expected construction to start by year-end 2026, contingent on development work and power arrangements. [#PR-2026-01-26] Company announcement. A subsequently reported town moratorium through April 7, 2027, and planned referendum make that timetable uncertain; a favorable resolution could restore optionality, while delay or cancellation would impair it.

Jamalco and restarted capacity stabilize output
2027-10-01
Century said Jamalco's new TG4 power turbine came online in August and reported Mt. Holly's final 90 pots restarted and Grundartangi Line 2 returned to near-full production. Sustained operation could improve shipment reliability, but the company has not quantified a separate forward earnings contribution for these changes. [#SEC-8K-2026-08-06] Company results.

Risks

Aluminum prices and regional premiums, alumina and other raw-material costs, and electricity costs can quickly change smelting margins. [#SEC-8K-2026-08-06]
Grundartangi equipment failures and Jamalco recovery create operating and insurance-recovery uncertainty. Company results.
Inola's reported moratorium through April 7, 2027, and planned referendum conflict with Century's original year-end 2026 construction expectation; legal and permitting outcomes remain uncertain. Company announcement; KOSU report.
Trade-policy changes could affect U.S. aluminum premiums; August tariff headlines are not confirmation of a final policy change.
