What matters now
- The model range is unusually wide (R$7.03 to R$21.08). The outcome hinges heavily on assumptions, so read the point estimate with caution.
- Solid but not exceptional quality (63/100) and above fair value, neither a clear bargain nor a standout compounder.
- For a financial, book-value and earnings-based methods matter more than a cash-flow DCF, which fits banks and insurers poorly.

Analysis
B3 S.A (B3SA3) currently trades at R$15.36, while our model-based Fair Value estimate is R$11.57, implying the stock looks roughly 24.7% overvalued today. We read business quality at 63/100 (solid quality), in the Financial Services 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: high).
Over the trailing twelve months, B3 S.A generated revenue of R$10.6B at a net margin of 47.0%. Revenue grew 20.3% year over year. It earns a return on equity of 26.7%. Net debt stands at R$13.3B. Fundamentals as of Jul 19, 2026
Our scenario range runs from R$7.03 (bear case) to R$21.08 (bull case); at R$15.36, 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 24% below its 52-week high and 32% above its 52-week low, currently below its 200-day average. For context, the median of 10 Financial Services peers we cover trades at -53% fair-value upside, at -25%, B3SA3 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 24 models by family
Widest divergence: Growth Earnings (R$21.15) versus Asset-Based (R$2.34). Highest evidence: Residual Income (76).
