Analysis
Voltalia SA (VLTSA) currently trades at €6.58, while our model-based Fair Value estimate is €7.45, implying the stock looks roughly 13.3% undervalued today. The Quality Score stands at 19/100 (below-average quality), in the Utilities 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, Voltalia SA generated revenue of €588M at a net margin of -21.8%. Revenue grew 17.6% year over year. It earns a return on equity of -9.3%. Net debt stands at €2.2B. Fundamentals as of Aug 13, 2026
Our scenario range runs from €4.25 (bear case) to €10.01 (bull case); at €6.58, 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 31% below its 52-week high and 12% above its 52-week low, currently below its 200-day average. For context, the median of 10 Utilities peers we cover trades at -11% fair-value upside, at 13%, VLTSA 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 4 models by family
Widest divergence: Asset-Based (€4.88) versus Dividend Discount (€4.06). Highest evidence: Gordon GGM (70).
