Fair value updated Aug 13, 2026, revised from €1.92 to €0.3700 (−80.7%) since Jul 24, 2026. Share price −26.4% over the past month.

Below-average quality, screening 34% undervalued on our models.

What matters now

  • The large discount to fair value meets weak quality (34/100). That raises the risk this is a value trap rather than a bargain.
  • The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.
  • A fairly wide model range (€0.2400 to €0.4600) leaves room in how you read the outcome.

Analysis

ATON Green Storage S.p.A (ATON) currently trades at €0.2760, while our model-based Fair Value estimate is €0.3700, implying the stock looks roughly 34.1% undervalued today. The Quality Score stands at 34/100 (below-average quality), in the Industrials sector. Bull case: trading below our estimate, it may offer upside if the fundamentals hold. Bear case: a low price can be a value trap when quality is weak or the data is thin (evidence: low), always confirm before acting.

Trailing-twelve-month revenue stands at €5.9M. Revenue declined 44.9% year over year. It earns a return on equity of -94.0%. Net debt stands at €25.7M. Fundamentals as of Aug 13, 2026

Our scenario range runs from €0.2400 (bear case) to €0.4600 (bull case); at €0.2760, 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. For context, the median of 10 Industrials peers we cover trades at -48% fair-value upside, at 34%, ATON screens cheaper 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.

Model Bear Bear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull Bull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. Evidence
