What matters now
The price is below even our cautious bear case (R$7.79). The market is more pessimistic than our downside scenario.
Solid quality (48/100) at a price below fair value, the discount is the argument here, not the business quality.
A fairly wide model range (R$7.79 to R$19.87) leaves room in how you read the outcome.
White line = price, green steps = our fair value per fiscal year, dashed = 300-day average. As of Aug 21, 2026.
How to read this chart
60‑month range R$3.08 – R$8.26 · fair‑value band R$7.79 – R$19.87 · the R$4.64 price screens below the R$13.53 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). Dashed = 300-day average. As of Aug 21, 2026.
Grupo Mateus S.A (GMAT3) currently trades at R$4.64, while our model-based Fair Value estimate is R$13.53, implying the stock looks roughly 191.6% undervalued today. The Quality Score stands at 48/100 (below-average quality), in the Consumer Cyclical 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: medium), always confirm before acting.
Over the trailing twelve months, Grupo Mateus S.A generated revenue of R$39.5B at a net margin of 4.5%. Revenue grew 12.9% year over year. It earns a return on equity of 16.0%. Net debt stands at R$5.0B. Fundamentals as of Aug 21, 2026
Our scenario range runs from R$7.79 (bear case) to R$19.87 (bull case); at R$4.64, the current price sits below 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 44% below its 52-week high and 15% above its 52-week low, currently below its 200-day average. For context, the median of 10 Consumer Cyclical peers we cover trades at -15% fair-value upside, at 192%, GMAT3 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.
ModelBear ⓘBear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull ⓘBull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target.Evidence

Non-valuation factor families (profitability, growth, cashflow, financial strength, momentum …), each academically grounded. Valuation itself sits in the Fair Value and is deliberately excluded here to avoid double-counting.
All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
