Analysis

Groupe Tera SA (ALGTR) currently trades at €4.18, while our model-based Fair Value estimate is €5.12, implying the stock looks roughly 22.4% undervalued today. The Quality Score stands at 40/100 (below-average quality), in the Technology 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: medium), always confirm before acting.

Over the trailing twelve months, Groupe Tera SA generated revenue of €14.2M at a net margin of -4.3%. Revenue grew 8.8% year over year. It earns a return on equity of -47.4%. The balance sheet holds a net cash position of €12.8M. Fundamentals as of Aug 13, 2026

Our scenario range runs from €3.84 (bear case) to €6.40 (bull case); at €4.18, 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. The share trades about 36% below its 52-week high and 67% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -46% fair-value upside, at 22%, ALGTR 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
