Quanta Services, Inc. (PWR): fair value, margin of safety and Wheel Score
Industrials · Engineering & Construction · United States · High Growth
Is PWR undervalued?
At 660.53 (close of 16 Oct 2026), PWR trades 158% over the GLS average fair value of 256.02, with 0 of 9 models above the price. The stock earns none of the Wheel Score's Value points at this price. That is a statement about price against trailing fundamentals, not about the company's prospects - the Wall Street View and the Growth tab on the Quote page carry the forward numbers.
There is a wide gap between DDM (6.47) and Payback Time (607.83). When the models are this far apart the "fair value" is really a range, and the margin of safety above should be read with that range in mind.
The nightly engine files PWR under High Growth: revenue and earnings growing fast enough that the growth-based models carry the valuation.
Nine valuation models for PWR
Each model turns the latest filed numbers into a value per share; the GLS fair value is the simple average of the ones that produce a positive number. The last two rows are shown for reference and never enter the average. The Quote page lets you switch any model off and add your own margin of safety.

| Lynch | 131.10 | -80% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |

Quality and financial health
Quanta Services, Inc. scores 5 of 9 on the Piotroski F-score: a middling result that falls one point short of the Sunday Scan's "6 or more" rule. Some of the nine tests on profitability, leverage and efficiency are failed, so the accounts are worth a look before selling a put on the name. A GLS Moat score of 8.1/10 puts PWR among the more durable businesses we track: over ten years the metrics the score watches (revenue, EPS, book value, margins, cash flow, ROIC) have mostly moved the right way, year after year.
Returns on capital are moderate - ROIC 6.7%, ROE 11.5%, ROA 4.1% - with debt at 0.72 times equity and a free-cash-flow yield of 2.4%.
The dividend yield is 0.07% with a payout ratio of 5% - a small yield that leaves most of the earnings in the business. Revenue comes mainly from Electric 82%, Underground and Infrastructure 18% (quarter Q2 FY2026).
Institutional ownership scores 10/10, insider activity 1/10 and Congressional trading 6/10 on the GLS smart-money scales; the last recorded Congressional buy was on 27 Aug 2026.
| Piotroski F-score | 5 / 9 | ROIC | 6.7% |
|---|---|---|---|
| GLS Moat | 8.1 / 10 | ROE | 11.5% |
| Debt / equity | 0.72 | ROA | 4.1% |
| Free-cash-flow yield | 2.4% | Payout ratio | 5% |
| Institutions | 10 / 10 | Insiders · Congress | 1 · 6 / 10 |
Wheel Score 61: Fair
A Wheel Score of 61 puts Quanta Services, Inc. in the Fair band - below the 70 the Sunday Scan requires. Value 0/25, Health 11/20, Moat 12/15, Premium 20/20 and Stability 18/20; the weakest part is Value (0/25).
Implied volatility is 52% on the near-the-money contracts 20-60 days out - inside the 35-60% range the Wheel Score pays full marks for: enough premium to be worth selling, not so much that the risk is unpaid. Chain open interest is 48,071 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 1.1M shares a day on a market cap of $99.3B, with a beta of 1.27 - a high beta, so the stock tends to move more than the market and a strike can be gapped through; the Stability part of the Wheel Score gives that 18 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 0 / 25 | -158% margin of safety | |
| Health | 11 / 20 | Piotroski 5/9 | |
| Moat | 12 / 15 | moat 8.1/10 | |
| Premium | 20 / 20 | implied volatility 52% | |
| Stability | 18 / 20 | 1.1M shares/day, $99.3B cap, beta 1.27 |
