Analysis

Bayer AG NA (BAYN) currently trades at €48.85, while our model-based Fair Value estimate is €52.73, implying the stock looks roughly 7.4% fairly valued today. The Quality Score stands at 46/100 (below-average quality), in the Healthcare sector. Bull case: the Multiples group reads highest at a median of €95.79 per share, and 6 of the 15 models we run sit above the €48.85 price. Bear case: the Growth DCF group reads lowest at €5.58, and 9 of the 15 models stay below the price. Evidence for this calculation is medium.

Over the trailing twelve months, Bayer AG NA generated revenue of €45.2B at a net margin of −4.8%. Revenue declined 2.4% year over year. It earns a return on equity of −6.9%. Net debt stands at €30.8B. Fundamentals as of Aug 29, 2026

Our scenario range runs from €39.32 (bear case) to €88.24 (bull case); at €48.85, 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 2% below its 52-week high and 99% above its 52-week low, currently above its 200-day average. For context, the median of 10 Healthcare peers we cover trades at −18% fair-value upside, at 8%, BAYN screens cheaper than that median.

Fair Value models

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.

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

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.
