Analysis
Priner Serviços Industriais S.A (PRNR3) currently trades at R$18.40, while our model-based Fair Value estimate is R$17.29, implying the stock looks roughly 6.0% fairly valued today. The Quality Score stands at 28/100 (below-average quality), in the Industrials sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: medium).
Over the trailing twelve months, Priner Serviços Industriais S.A generated revenue of R$1.6B at a net margin of 2.3%. Revenue grew 14.2% year over year. It earns a return on equity of 11.6%. Net debt stands at R$467M. Fundamentals as of Jul 14, 2026
Our scenario range runs from R$10.04 (bear case) to R$23.35 (bull case); at R$18.40, 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 17% below its 52-week high and 28% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at -45% fair-value upside, at -6%, PRNR3 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 16 models by family
