What matters now
- Weak quality (34/100) and above fair value at the same time, the margin of safety is missing on both counts.
- A fairly wide model range ($42.93 to $87.60) leaves room in how you read the outcome.

Analysis
National Grid PLC ADR (NGG) currently trades at $78.17, while our model-based Fair Value estimate is $63.94, implying the stock looks roughly 22.2% overvalued today. The Quality Score stands at 34/100 (below-average quality), in the Utilities sector. Bull case: the Growth Earnings group reads highest at a median of $49.94 per share, and 0 of the 15 models we run sit above the $78.17 price. Bear case: the Economic Profit group reads lowest at $12.95, and 15 of the 15 models stay below the price. Evidence for this calculation is high.
Over the trailing twelve months, National Grid PLC ADR generated revenue of $17.7B at a net margin of 18.3%. Revenue grew 2.0% year over year. It earns a return on equity of 8.4%. Net debt stands at $46.4B. Fundamentals as of Aug 14, 2026
Our scenario range runs from $42.93 (bear case) to $87.60 (bull case); at $78.17, 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 15% below its 52-week high and 21% above its 52-week low, currently below its 200-day average. For context, the median of 10 Utilities peers we cover trades at −38% fair-value upside, at −18%, NGG screens cheaper 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 $1.69 per share, which is 2.6 % 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 15 models by family
Widest divergence: Growth Earnings ($49.94) versus Economic Profit ($12.95). Highest evidence: Residual Income (76).

Quality Score breakdown
Of which business quality 34 · Market factors (momentum, volatility) 58
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.
