Analysis
Quanta Services Inc (PWR) currently trades at $620.06, while our model-based Fair Value estimate is $143.92, implying the stock looks roughly 330.8% overvalued today. The Quality Score stands at 50/100 (solid quality), in the Industrials sector. Bull case: the DCF Models group reads highest at a median of $195.79 per share, and 0 of the 26 models we run sit above the $620.06 price. Bear case: the Asset-Based group reads lowest at $39.91, and 26 of the 26 models stay below the price. Evidence for this calculation is high.
Over the trailing twelve months, Quanta Services Inc generated revenue of $30.1B at a net margin of 3.7%. Revenue grew 26.3% year over year. It earns a return on equity of 13.5%. Net debt stands at $748M. Fundamentals as of Sep 5, 2026
Our scenario range runs from $106.78 (bear case) to $179.90 (bull case); at $620.06, 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 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. The share trades about 21% below its 52-week high and 82% 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 −77%, PWR 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 $4.64 per share, which is 3.2 % 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: DCF Models ($195.79) versus Dividend Discount ($6.48). Highest evidence: EPV (74).

Quality Score breakdown
Of which business quality 52 · Market factors (momentum, volatility) 61
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.
