Highlights

How we pick these

Strengths

  • High operating margin. 25.3% of revenue is left as operating profit, against a median of 7.0% for materials companies we cover.
  • Margins widening. Operating margin is up 18.9 points on a year ago.
  • Net cash. Cash exceeds long-term debt by $0.3bn.

Things to watch

  • Results due soon. Results are expected around 6 November; the share price can move sharply on the day.
  • Volatile shares. Over the past year the shares showed annualised volatility of 63% and a beta of 1.6 against the S&P 500.
  • Insiders selling. 10 insiders sold $625M of stock over the past 365 days and none bought (2% under pre-set trading plans).
  • Weak cash conversion. Free cash flow was 25% of net income over the last 12 months.
  • Below peers: stock pay as % of revenue. Stock pay as % of revenue of 1.7% ranks 105 of 137 materials companies we cover (median 0.7%).
  • Heavily shorted. 13.7% of the shares available to trade are sold short (4.9 days of average volume to cover).

Valuation

Century Aluminum Co valuation models and calculator

Fundamentalytics rating

model v1.6 · 2026-11-03

Not rated: held for review: our cash-flow value ($3.57) was left out of our combined valuation (it is 0.11x the share price, outside the 0.2-5x range we accept), so it can't be the basis of a rating.

Our value per share comes from a discounted-cash-flow model of Century Aluminum Co's free cash flow after stock-based pay ( $23.9M, FY2026 Q2 TTM, with after-tax interest added back): growth for five years as below (the first two years from forecasts, guidance and the company's record), fading to 2.5%, discounted at 8.5%, then cash added and debt and other claims subtracted. These are model values under stated assumptions, not price targets or recommendations.

The inputs used by the models below have passed source checks. Individual model values are available below and in the interactive valuator. Their differences are shown explicitly; the platform combined value and recommendation remain withheld.

Valuation models

We value Century Aluminum Co as an operating company, with every model that fits that kind of business. Cost of equity 11%: the 10-year Treasury yield (4.9%) plus a beta of 1.34 times a 4.5% equity risk premium.

Different models fail in different ways, so where several apply we average them rather than trust one. Peer-based models compare Century Aluminum Co with Materials sector in our coverage, using third-party market data.

Moat

28 /100

Weak moat

How hard Century Aluminum's competitive advantage looks for rivals to wear away, judged from 10 years of its own filings: returns on capital, pricing power, profit durability, cash conversion and discipline.

  • Returns on capital 0 / 20

    Net income has been a median 0.2% of total assets over 10 years.

  • Pricing power 3 / 20

    Gross margin has been a median 2.2%, moving by 6.6 percentage points (standard deviation) across 10 years.

  • Durability 10 / 20

    Operating margin has been a median -1.2%; its worst year was -13.3%.

  • Cash conversion 2 / 20

    Free cash flow was positive in 2 of 10 years, at a median -0.7% of revenue.

  • Discipline 13 / 20

    The diluted share count rose 10.8% over five years; stock-based pay has been a median 0.4% of revenue.

AI disruption exposure: Low. In this industry, the business rests on physical assets, regulated networks or products AI itself depends on.

Free cash flow is cash from operations minus capital spending. Growth is left blank when last year's figure was a loss or under 2% of revenue. Share counts and EPS are restated for stock splits. A dash means the company didn't report the figure.
