Bio-Gate AG (BIG1) Fair Value & Analysis
Healthcare · DE · Market cap €6.8M
Fair value as of: Jul 18, 2026
From 1 valuation models · updated 23 days ago
Share price +450.4% over the past month.
Below-average quality, and screening another 85% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case (€0.7500). The favourable scenario is already priced in.
- Weak quality (35/100) 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 (€0.4000 to €0.7500) leaves room in how you read the outcome.

Analysis
Bio-Gate AG (BIG1) currently trades at €3.28, while our model-based Fair Value estimate is €0.5000, implying the stock looks roughly 84.7% overvalued today. The Quality Score stands at 35/100 (below-average quality), in the Healthcare 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, Bio-Gate AG generated revenue of €7.0M at a net margin of -19.7%. Revenue declined 2.8% year over year. It earns a return on equity of -87.8%. Fundamentals as of Jul 18, 2026
Our scenario range runs from €0.4000 (bear case) to €0.7500 (bull case); at €3.28, 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. For context, the median of 10 Healthcare peers we cover trades at -43% fair-value upside, at -85%, BIG1 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.

A separate quality layer scores the fundamentals. Every input is real reported data, nothing guessed.
