Analysis
CSN Mineração S.A (CMIN3) currently trades at R$5.45, while our model-based Fair Value estimate is R$6.44, implying the stock looks roughly 18.1% undervalued today. The Quality Score stands at 50/100 (solid quality), in the Basic Materials sector. Bull case: trading below our estimate, it may offer upside if the fundamentals hold. Bear case: a low price can be a value trap when quality is weak or the data is thin (evidence: high), always confirm before acting.
Over the trailing twelve months, CSN Mineração S.A generated revenue of R$17.8B at a net margin of 12.5%. Revenue declined 5.3% year over year. It earns a return on equity of 25.7%. Net debt stands at R$449M. Fundamentals as of Jul 16, 2026
Our scenario range runs from R$4.83 (bear case) to R$8.05 (bull case); at R$5.45, the current price sits within that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades about 15% below its 52-week high and 34% above its 52-week low, currently above its 200-day average. For context, the median of 10 Basic Materials peers we cover trades at -7% fair-value upside, at 18%, CMIN3 screens cheaper than that median.
Fair Value models
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small.
All 17 models by family
Widest divergence: Growth Earnings (R$10.32) versus Asset-Based (R$0.8200). Highest evidence: Residual Income (76).
