Century Aluminum Company (CENX) has a Lemma Quality Score of 6.7 out of 10 as of October 19, 2026, which reads as solid quality. A solid reading is a respectable business with clear strengths and at least one area that falls short of the best in its field. Five pillars feed it, and every one of them is computed from what the company reported rather than from its share price.
Among the 77 Materials companies with a published score, that ranks at the 83rd percentile, among the stronger quarter of the group. The median across the group is 4.4, and the top quarter begins at 6.2, so Century Aluminum Company is well above the typical company here.
On profitability, Century Aluminum Company scores 8.4, a strong reading. Its peers have a median of 4.4 across 74 Materials companies, which places it well above them, at the 93rd percentile. A reading this strong says the business earns well on what it sells and on the capital it uses, the kind of margin profile competitors find hard to copy.
Century Aluminum Company’s solvency score is 8.2 out of 10 (strong). Against a median of 6.7 among 66 Materials companies, that is above the group and the 72nd percentile. Strong solvency points to a balance sheet that can carry its debts comfortably, with interest well covered and little pressure from creditors.
On growth, Century Aluminum Company scores 5.9, an average reading. Its peers have a median of 3.2 across 57 Materials companies, which places it well above them, at the 80th percentile. Growth near the median is neither a reason to buy nor a concern, but it does mean the quality case rests more on the other pillars.
Efficiency scores 8.3 out of 10, which reads as strong. None of the other Materials companies scores higher here, against a median of 5.2 across 71 of them. High efficiency means assets and earnings are being turned into cash and output better than at most peers, a sign of a well run operation.
Predictability scores 2.5 out of 10, which reads as weak. The median across 76 Materials companies is 4.5, so Century Aluminum Company is well below its peers on this pillar and ranks at the 21st percentile. When results are this uneven, the averages behind the other pillars hide a lot of movement, and a longer history tells more than the latest year.
This is a lopsided profile. Profitability scores 8.4 but predictability only 2.5, a gap of 5.9 points, so the overall hides a business that is excellent in one respect and weak in another. Leading with profitability is the most valuable kind of strength, because margins and returns are what the other pillars ultimately feed. A predictability shortfall means the record is volatile, so the averages behind the other pillars move more than they appear to.
The pillar with the most room to move the score is predictability. If it rose to the median of Materials companies, 4.5, Century Aluminum Company’s overall score would go from 6.7 to about 7.1. All five pillars could be scored, so the overall uses the full set of weights out of 100: profitability 25, solvency 20, growth 20, efficiency 15, predictability 20.
These are the Materials companies closest to Century Aluminum Company in market value. Each has its own page scored on the same five pillars, so the comparison is like for like.
How much profit the company generates from its capital and sales.
The company’s ability to service debt and meet its obligations.
How fast revenue, earnings and cash flow are compounding.
How well assets and earnings convert into cash and output.
How stable and consistent results have been over time.
Each metric is scored from 0 to 10 against sector-aware benchmarks, where higher is better. Metrics roll up into five pillars, and the pillars combine into the overall score using the weights shown. Sector-sensitive metrics are judged relative to peers in the same sector.
This score is a systematic, backward-looking read of reported fundamentals. It does not judge valuation, management quality, competitive moat, or future prospects, and can be distorted by one-off items or unusual accounting. Treat it as a starting point, not a recommendation.

No. Quality and valuation are separate questions, and a good business at the wrong price is still a bad purchase. Score the business here, then price it with a DCF you control.
Inside Lemma Analysis the same five pillars run on every company we cover, with the metrics behind each one, current fundamentals, a DCF you control and a watchlist that tells you when the price catches up.
