Analysis
Natural Gas Services Group (NGS) currently trades at $37.01, while our model-based Fair Value estimate is $18.03, implying the stock looks roughly 51.3% overvalued today. The Quality Score stands at 59/100 (solid 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, Natural Gas Services Group generated revenue of $179M at a net margin of 12.2%. Revenue grew 17.1% year over year. It earns a return on equity of 8.1%. Net debt stands at $230M. Fundamentals as of Jul 18, 2026
Our scenario range runs from $15.49 (bear case) to $27.01 (bull case); at $37.01, 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 16% below its 52-week high and 65% above its 52-week low, currently above its 200-day average. For context, the median of 10 Energy peers we cover trades at -36% fair-value upside, at -51%, NGS 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 ($32.71) versus Dividend Discount ($2.62). Highest evidence: Growth DCF (80).
