Century Aluminum (CENX) reported third-quarter earnings of $2.89 per share, beating the $2.61 consensus by 10.7%. Earnings grew 1826.7% from a year ago. Revenue of $961.2 million rose 52.0% year over year but missed the $992.4 million consensus by 3.1%. The year-over-year comparison is spectacular, but it is not the real story. The central tension is that Century has finally reached full operating capacity and generated a dramatic cash build, yet earnings momentum is flattening. Management's fourth-quarter outlook points lower.

The quality of the beat deserves scrutiny. The $2.89 figure is GAAP diluted EPS, and it includes $31.0 million of net exceptional items. These include $34.5 million of after-tax unrealized derivative gains and a $12.7 million insurance gain, partially offset by $15.1 million of Iceland equipment-failure costs. Stripping those out, adjusted EPS was $2.58, a few cents below the $2.61 consensus and only modestly above the second quarter's $2.46. Adjusted EBITDA attributable to Century was $331.6 million, up just $4.7 million sequentially. That result landed in the lower half of management's own $325-$345 million guide.

The top line shows what is working. Shipments jumped to 173,483 tonnes from 130,632 in the second quarter. The driver was the Grundartangi Line 2 restart, which lifted Iceland volumes to 75,300 tonnes from 35,575. Pricing has done much of the heavy lifting from a year ago. Primary aluminum sales of $896.9 million came on about 7% more tonnage than the year-ago quarter's $563.9 million, reflecting much stronger realized metal prices and U.S. premiums. Management said all assets ran at full capacity for the first time in a decade. It expects unit-cost benefits from fuller absorption to persist into 2027.

The conversion of that activity into profit was less clean:

• Higher operating expenses tied to Mt. Holly production instability offset much of the volume gain.
• Extreme summer heat hurt power price realization.
• Management describes the Mt. Holly instability as resolved, but off-spec material from that period will still weigh on fourth-quarter sales mix.

The fourth-quarter outlook is the clearest crack in the story. Management guided adjusted EBITDA to $275-$300 million, well below the third quarter's $332 million. The main driver is a $35-$45 million pricing headwind, with lagged LME expected around $3,150 per tonne versus $3,400 realized in the third quarter. Additional pressure comes from a $5-$10 million raw-material hit, as Middle East tensions lift coke and heavy fuel oil costs, and roughly $5 million of higher operating expense. A firmer European premium, with spot near $575 per tonne, provides only partial offset. Persistent bauxite quality problems at Jamalco add another drag that management says will take several quarters to resolve.

The balance sheet transformation is genuinely significant. Cash and restricted cash reached roughly $755 million against about $486 million of debt, putting Century in a net cash position. Cash flow of about $365 million exceeded adjusted EBITDA. Total liquidity stood at $1.16 billion. About $125 million of 2026 growth capex is complete, so spending should normalize. Further cash support may come from an expected $80 million 45X credit in 2027, ongoing Iceland insurance recoveries, and a $300 million put right on the Hawesville data-center stake. The Hawesville stake has been further de-risked by Fluor's appointment as EPC contractor and Google's credit support.

Bears have legitimate ammunition on the Oklahoma smelter. Financing terms are largely agreed, and the power contract is in final documentation. However, management no longer reiterated the explicit end-of-2026 target for a final investment decision and groundbreaking that it set on prior calls. It referred instead to the "coming months" amid ongoing community and regulatory concerns. Shareholder returns, which earlier looked likely, are now explicitly deferred until that decision. The cash pile is real, but its deployment is tied to a timeline that just softened.

The market has been punishing the stock regardless of these results. Shares fell 31.5% from the $47.85 open after the August report to $32.80. They sit about 34% below the 200-day moving average and only 6.7% above the inter-earnings low of $30.75 set on October 26. That is roughly 41% off the August high. Investor sentiment improved from slightly negative to slightly positive heading into the report, a meaningful shift but not an enthusiastic one. Earnings Whispers trend readings are mixed: sequential growth and momentum are positive, while price and AVWAP trends remain negative.

The bottom line is that Century delivered an operationally pivotal quarter, with full capacity, record cash generation, and a net cash balance sheet. The headline beat, however, overstates its earnings strength. On an adjusted basis, results were roughly in line with expectations, and the fourth-quarter guide implies a sequential step down as metal prices ease and costs rise. With Oklahoma timing slipping and capital returns on hold, the stock's steep drawdown suggests investors are discounting peak-cycle earnings. That leaves management needing to show that full-capacity cost gains and a smelter decision can carry the story into 2027.
