Analysis
2G Energy AG (2GB) currently trades at €57.50, while our model-based Fair Value estimate is €10.57, implying the stock looks roughly 81.6% overvalued today. The Quality Score stands at 48/100 (below-average quality), in the Industrials 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, 2G Energy AG generated revenue of €416M at a net margin of 5.9%. Revenue grew 29.8% year over year. It earns a return on equity of 18.3%. Net debt stands at €10.2M. Fundamentals as of Jul 13, 2026
Our scenario range runs from €7.45 (bear case) to €13.34 (bull case); at €57.50, 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 22% below its 52-week high and 131% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at -48% fair-value upside, at -82%, 2GB 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 17 models by family
