What matters now
- Solid quality (47/100) at a price below fair value, the discount is the argument here, not the business quality.
- The price sits in the lower half of our model range, the side with the larger margin of safety.
- The data supports the verdict: every model runs on fully documented inputs.

How to read this chart
60‑month range €92.54 – €279.43 · fair‑value band €184.24 – €331.48 · the €203.20 price screens below the €265.19 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). Dashed = 300-day average. As of Sep 3, 2026.
Analysis
Acciona (ANA) currently trades at €203.20, while our model-based Fair Value estimate is €265.19, implying the stock looks roughly 23.4% undervalued today. The Quality Score stands at 47/100 (below-average quality), in the Industrials sector. Bull case: the Growth Earnings group reads highest at a median of €644.40 per share, and 17 of the 26 models we run sit above the €203.20 price. Bear case: the Asset-Based group reads lowest at €57.85, and 9 of the 26 models stay below the price. Evidence for this calculation is high.
Over the trailing twelve months, Acciona generated revenue of €21.5B at a net margin of 3.7%. Revenue declined 1.7% year over year. It earns a return on equity of 17.8%. Net debt stands at €8.2B. Fundamentals as of Sep 3, 2026
Our scenario range runs from €184.24 (bear case) to €331.48 (bull case); at €203.20, 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. Analysts expect earnings well below the last reported figure (earnings in transition, for example expiring patents or contracts); a fair value that looks fair on trailing earnings may then be too optimistic. The share trades about 24% below its 52-week high and 48% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at −46% fair-value upside, at 31%, ANA screens cheaper 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 €6.10 per share, which is 2.3 % 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 (€644.40) versus Asset-Based (€57.85). Highest evidence: EPV (74).

Quality Score breakdown
Of which business quality 44 · Market factors (momentum, volatility) 51
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.
