Fair value as of: Jul 19, 2026
From 1 valuation models · updated 22 days ago
Share price +1.3% over the past month.
Below-average quality, and screening another 67% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case (€2.24). The favourable scenario is already priced in.
- Weak quality (30/100) and above fair value at the same time, the margin of safety is missing on both counts.
- 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 (€1.12 to €2.24) leaves room in how you read the outcome.

Analysis
Rubean AG (R1B) currently trades at €4.54, while our model-based Fair Value estimate is €1.50, implying the stock looks roughly 66.9% overvalued today. The Quality Score stands at 30/100 (below-average quality), in the Technology 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: low).
Over the trailing twelve months, Rubean AG generated revenue of €1.8M at a net margin of -93.3%. Revenue declined 10.2% year over year. It earns a return on equity of -21.0%. Fundamentals as of Jul 19, 2026
Our scenario range runs from €1.12 (bear case) to €2.24 (bull case); at €4.54, 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 50% below its 52-week high and 12% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -50% fair-value upside, at -67%, R1B 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.
