What matters now
- The price sits above even our optimistic bull case (€26.34). The favourable scenario is already priced in.
- Solid but not exceptional quality (61/100) and above fair value, neither a clear bargain nor a standout compounder.
- A fairly wide model range (€10.89 to €26.34) leaves room in how you read the outcome.

Analysis
Renk Group AG (R3NK) currently trades at €43.16, while our model-based Fair Value estimate is €21.08, implying the stock looks roughly 104.8% overvalued today. The Quality Score stands at 61/100 (solid quality), in the Industrials sector. Bull case: the Growth Earnings group reads highest at a median of €40.68 per share, and 2 of the 26 models we run sit above the €43.16 price. Bear case: the Asset-Based group reads lowest at €3.25, and 24 of the 26 models stay below the price. Evidence for this calculation is high.
Over the trailing twelve months, Renk Group AG generated revenue of €1.4B at a net margin of 8.4%. Revenue grew 4.0% year over year. It earns a return on equity of 24.2%. Net debt stands at €383M. Fundamentals as of Sep 5, 2026
Our scenario range runs from €10.89 (bear case) to €26.34 (bull case); at €43.16, 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 last reported earnings sit well below what analysts expect (earnings in transition, for example after write-downs or an earnings dip); whether the stock is cheap or expensive hinges on the expected recovery actually arriving. Read the fair value with that caveat. The share trades about 52% below its 52-week high and 2% above its 52-week low, currently below its 200-day average. For context, the median of 10 Industrials peers we cover trades at −44% fair-value upside, at −51%, R3NK screens richer than that median.
Fair Value models
This estimate rests on fiscal year 2025 figures, and about 8 months have passed since. In that time the company retained roughly €0.3790 per share, which is 1.8 % of the fair value. The fair value deliberately does not add this in: the models value reported figures, not a projection.
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted, family-balanced 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. Every input is real reported data, nothing guessed.
All 26 models by family
Widest divergence: Growth Earnings (€40.68) versus Asset-Based (€3.25). Highest evidence: FCF DCF (74).

Quality Score breakdown
Of which business quality 58 · Market factors (momentum, volatility) 11
Non-valuation factor families (profitability, growth, cashflow, financial strength, momentum …), each academically grounded. Valuation itself sits in the Fair Value and is deliberately excluded here to avoid double-counting.
All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
