Our scenario range runs from R$7.19 (bear case) to R$13.72 (bull case); at R$8.51, the current price sits within that range.

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
Widest divergence: Growth Earnings (R$11.36) versus Dividend Discount (R$2.46). Highest evidence: Residual Income (76).
