Analysis

Telefónica, S.A (TEFN) currently trades at 75.67 MXN, while our model-based Fair Value estimate is 108.96 MXN, implying the stock looks roughly 44.0% undervalued today. The Quality Score stands at 46/100 (below-average 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: medium), always confirm before acting.

Over the trailing twelve months, Telefónica, S.A generated revenue of 35.9B MXN at a net margin of -9.5%. Revenue declined 12.4% year over year. It earns a return on equity of -8.9%. Net debt stands at 25.5B MXN. Fundamentals as of Aug 13, 2026

Our scenario range runs from 80.47 MXN (bear case) to 137.33 MXN (bull case); at 75.67 MXN, 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 21% below its 52-week high and 4% above its 52-week low, currently below its 200-day average. For context, the median of 10 Communication Services peers we cover trades at 14% fair-value upside, at 44%, TEFN 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.

Widest divergence: DCF Models (459.31 MXN) versus Asset-Based (94.43 MXN). Highest evidence: Growth DCF (80).
