Analysis
Teixeira Duarte, S.A (TDSA) currently trades at €0.4800, while our model-based Fair Value estimate is €1.20, implying the stock looks roughly 150.0% undervalued today. The Quality Score stands at 52/100 (solid quality), in the Industrials 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, Teixeira Duarte, S.A generated revenue of €717M at a net margin of 7.0%. Revenue declined 1.8% year over year. It earns a return on equity of 31.7%. Net debt stands at €467M. Fundamentals as of Jul 25, 2026
Our scenario range runs from €0.8100 (bear case) to €2.46 (bull case); at €0.4800, 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 41% below its 52-week high and 78% above its 52-week low, currently below its 200-day average. For context, the median of 10 Industrials peers we cover trades at -45% fair-value upside, at 150%, TDSA 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.
