Analysis
TIM S.A (TIMB) currently trades at $18.43, while our model-based Fair Value estimate is $39.00, implying the stock looks roughly 111.6% undervalued today. The Quality Score stands at 64/100 (solid quality), in the Communication Services 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, TIM S.A generated revenue of $27.0B at a net margin of 16.0%. Revenue grew 6.5% year over year. It earns a return on equity of 17.7%. Net debt stands at $28.5B. Fundamentals as of Jul 21, 2026
Our scenario range runs from $29.25 (bear case) to $48.75 (bull case); at $18.43, 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 35% below its 52-week high and 10% above its 52-week low, currently below its 200-day average. For context, the median of 10 Communication Services peers we cover trades at 32% fair-value upside, at 112%, TIMB 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 26 models by family
Widest divergence: DCF Models ($271.90) versus Asset-Based ($33.63). Highest evidence: Growth DCF (80).

A separate quality layer scores the fundamentals. Every input is real reported data, nothing guessed.
