What matters now
- A high-quality business (quality 75/100), yet the market already pays well above fair value. Quality at a full price, with little margin of safety.
- The model range is unusually wide (€72.73 to €318.69). The outcome hinges heavily on assumptions, so read the point estimate with caution.

How to read this chart
60‑month range €51.48 – €216.20 · fair‑value band €72.73 – €318.69 · the €216.20 price screens above the €95.01 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). Dashed = 300-day average. As of Aug 29, 2026.
Analysis
Gaztransport & Technigaz SAS (GTT) currently trades at €216.20, while our model-based Fair Value estimate is €95.01, implying the stock looks roughly 127.5% overvalued today. The Quality Score stands at 75/100 (high quality), in the Energy sector. Bull case: the Growth Earnings group reads highest at a median of €245.14 per share, and 7 of the 26 models we run sit above the €216.20 price. Bear case: the Asset-Based group reads lowest at €10.63, and 19 of the 26 models stay below the price. Evidence for this calculation is high.
Over the trailing twelve months, Gaztransport & Technigaz SAS generated revenue of €803M at a net margin of 51.5%. Revenue grew 19.6% year over year. It earns a return on equity of 78.7%. The balance sheet holds a net cash position of €218M. Fundamentals as of Aug 29, 2026
Our scenario range runs from €72.73 (bear case) to €318.69 (bull case); at €216.20, 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 near its 52-week high and 50% above its 52-week low, currently above its 200-day average. For context, the median of 10 Energy peers we cover trades at −41% fair-value upside, at −56%, GTT screens richer than that median.
Fair Value models
This estimate rests on fiscal year 2025 figures, and about 8 months have passed since. In that time the company retained roughly €1.26 per share, which is 1.3 % of the fair value. The fair value deliberately does not add this in: the models value reported figures, not a projection.
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted, family-balanced 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. Every input is real reported data, nothing guessed.
All 26 models by family
Widest divergence: Growth Earnings (€245.14) versus Asset-Based (€10.63). Highest evidence: FCF DCF (76).

Quality Score breakdown
Of which business quality 76 · Market factors (momentum, volatility) 79
Non-valuation factor families (profitability, growth, cashflow, financial strength, momentum …), each academically grounded. Valuation itself sits in the Fair Value and is deliberately excluded here to avoid double-counting.
All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
