The Quality Score stands at 53/100 (solid quality), in the Utilities sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: medium).
Over the trailing twelve months, Thessaloniki Water Supply & Sewerage Co generated revenue of €87.5M at a net margin of 8.8%. Revenue declined 5.3% year over year. It earns a return on equity of 4.1%. The stock trades on a trailing P/E of 20.6. Fundamentals as of Jul 17, 2026
Our scenario range runs from €2.87 (bear case) to €3.88 (bull case); at €4.59, the current price sits above 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 near its 52-week high and 45% above its 52-week low, currently above its 200-day average. For context, the median of 10 Utilities peers we cover trades at -10% fair-value upside, at -24%, EYAPS screens richer 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 12 models by family
