What matters now
- The price sits above even our optimistic bull case (kr 66.56). The favourable scenario is already priced in.
- Weak quality (40/100) and above fair value at the same time, the margin of safety is missing on both counts.
- The model range is unusually wide (kr 18.77 to kr 66.56). The outcome hinges heavily on assumptions, so read the point estimate with caution.

Analysis
TGS NOPEC Geophysical Company ASA (TGS) currently trades at kr 137.30, while our model-based Fair Value estimate is kr 48.33, implying the stock looks roughly 64.8% overvalued today. The Quality Score stands at 40/100 (below-average quality), in the Energy 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: high).
Over the trailing twelve months, TGS NOPEC Geophysical Company ASA generated revenue of 1.3B NOK at a net margin of -0.2%. Revenue declined 42.2% year over year. It earns a return on equity of -0.1%. Net debt stands at 438M NOK. Fundamentals as of Aug 20, 2026
Our scenario range runs from kr 18.77 (bear case) to kr 66.56 (bull case); at kr 137.30, 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 about 13% below its 52-week high and 104% above its 52-week low, currently above its 200-day average. For context, the median of 10 Energy peers we cover trades at -40% fair-value upside, at -65%, TGS 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 26 models by family
Widest divergence: DCF Models (kr 205.40) versus Earnings-Based (kr 10.96). Highest evidence: Growth DCF (80).
