Analysis
Riber S.A (ALRIB) currently trades at €9.78, while our model-based Fair Value estimate is €1.93, implying the stock looks roughly 80.3% overvalued today. The Quality Score stands at 58/100 (solid 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: high).
Over the trailing twelve months, Riber S.A generated revenue of €40.3M at a net margin of 13.0%. Revenue grew 8.0% year over year. It earns a return on equity of 20.6%. The balance sheet holds a net cash position of €5.7M. Fundamentals as of Jul 15, 2026
Our scenario range runs from €1.41 (bear case) to €2.86 (bull case); at €9.78, 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 47% below its 52-week high and 301% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -75% fair-value upside, at -80%, ALRIB 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 20 models by family
Widest divergence: Growth Earnings (€4.20) versus Dividend Discount (€0.7900). Highest evidence: Growth DCF (80).
