Analysis
BT Group (BT-A) currently trades at £2.02, while our model-based Fair Value estimate is £1.49, implying the stock looks roughly 35.5% overvalued today. The Quality Score stands at 51/100 (solid quality), in the Communication Services sector. Bull case: the Multiples group reads highest at a median of £2.40 per share, and 8 of the 23 models we run sit above the £2.02 price. Bear case: the Growth DCF group reads lowest at £0.8100, and 15 of the 23 models stay below the price. Evidence for this calculation is high.
Over the trailing twelve months, BT Group generated revenue of £19.7B at a net margin of 5.5%. Revenue declined 3.9% year over year. It earns a return on equity of 8.5%. Net debt stands at £22.5B. Fundamentals as of Aug 27, 2026
Our scenario range runs from £1.10 (bear case) to £2.66 (bull case); at £2.02, 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 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. For context, the median of 10 Communication Services peers we cover trades at 30% fair-value upside, at −26%, BT-A screens richer than that median.
Fair Value models
This estimate rests on fiscal year 2026 figures, and about 5 months have passed since. In that time the company retained roughly £0.0121 per share, which is 0.8 % 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 23 models by family
Widest divergence: Multiples (£2.40) versus Growth DCF (£0.8100). Highest evidence: Residual Income (76).

Quality Score breakdown
Of which business quality 48 · Market factors (momentum, volatility) 53
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.
