Price vs Fair Value (5 years)
White line = price, green steps = our fair value per fiscal year, dashed = 300-day average. As of Aug 31, 2026.
How to read this chart
60‑month range €6.48 – €28.34 · fair‑value band €13.35 – €20.44 · the €27.74 price screens above the €19.07 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). 1 fiscal year is left out: there the valuation rested on only a fraction of the usual models. Dashed = 300-day average. As of Aug 31, 2026.
Analysis
Repsol S.A. (REP) currently trades at €27.74, while our model-based Fair Value estimate is €19.07, implying the stock looks roughly 45.5% overvalued today. The Quality Score stands at 57/100 (solid quality), in the Energy sector. Bull case: the Multiples group reads highest at a median of €24.36 per share, and 2 of the 24 models we run sit above the €27.74 price. Bear case: the Growth DCF group reads lowest at €8.54, and 22 of the 24 models stay below the price. Evidence for this calculation is high.
Over the trailing twelve months, Repsol S.A. generated revenue of €49.6B at a net margin of 5.0%. Revenue grew 8.4% year over year. It earns a return on equity of 9.5%. Net debt stands at €13.2B. Fundamentals as of Aug 31, 2026
Our scenario range runs from €13.35 (bear case) to €20.44 (bull case); at €27.74, 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 near its 52-week high and 152% above its 52-week low, currently above its 200-day average. For context, the median of 10 Energy peers we cover trades at −17% fair-value upside, at −31%, REP 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 €0.7399 per share, which is 3.9 % 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 24 models by family
Widest divergence: Multiples (€24.36) versus Growth DCF (€8.54). Highest evidence: FCF DCF (74).

Quality Score breakdown
Of which business quality 55 · Market factors (momentum, volatility) 89
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.
