Quanta Services
Combined average of Moat (AI Resilience), Growth, and Valuation scores.
Moat Score
The largest specialty electrical and pipeline contractor in North America with a 20,000+ skilled-craft workforce and multi-decade master service agreements with US investor-owned utilities — a moat built on labour scarcity, safety record, and utility relationship depth.
Quanta's moat is scarce skilled craft labour plus utility customer entrenchment — neither can be replicated quickly, and both are accelerating as the AI grid build-out collides with a structural lineman shortage:
- Lineman and Skilled-Craft Scarcity: The US faces a multi-decade shortage of qualified linemen, transmission engineers, and high-voltage substation technicians. Quanta operates the country's largest private lineman training college (Northwest Lineman College) and its captive workforce of 20,000+ craft labourers is effectively impossible to replicate — competitors must hire from the same scarce pool, which advantages the largest, best-paying employer.
- Utility Master Service Agreements: Quanta holds long-tenured MSAs with most US investor-owned utilities. These framework contracts provide first-call status on transmission, distribution, and substation work for the duration of the relationship — switching contractors mid-program is operationally painful for utilities and rarely happens once Quanta is embedded.
- Self-Perform Scale and Equipment Fleet: Quanta self-performs ~85% of its work versus subcontracting, owns one of the largest specialised heavy equipment fleets in the industry, and runs proprietary safety and productivity systems. This vertical integration is the reason it converts backlog at higher margins than smaller rivals and wins large EPC awards on schedule certainty.
Moat Verdict
Quanta is the cleanest pure-play on the US grid build-out and AI power demand, with a genuinely scarce moat in skilled craft labour and entrenched utility relationships. The franchise is durable for the cycle's duration; the only meaningful risk is valuation, which already prices in a long super-cycle with little room for disappointment.

physical EPC services contractor, no end-user interface.
Proprietary project management, safety, and productivity systems are real internal tooling but not an externally defensible software franchise.
no public-data moat.
Quanta's 20,000+ craft workforce, captive Northwest Lineman College training pipeline, and ability to pay top-of-market wages compound as the US lineman shortage deepens — this is the single most durable moat the company has.
Self-perform across transmission, distribution, substation, communications and renewables interconnect lets Quanta bid integrated EPC scope smaller specialists cannot. Breadth is real but unproven as a lock — no attach rate, retention figure or failed-unbundler on file — so it rates intact.
Decades of project execution data inform bid pricing and safety analytics, but the data is internal and not externally monetised.
Utility prequalification, OSHA safety records, and union/IBEW relationships create real new-entrant barriers — clearing them takes years and a clean incident history.
services contractor with no network effect.
Master service agreements and multi-year framework contracts with most US IOUs make Quanta a default first-call contractor for a program's life. MSAs are re-bid and rivals (MasTec, MYR, Primoris) hold them too, and no renewal figure is on file, so it rates intact.

The largest specialty utility contractor: fleet, equipment and crew scale win large programmes, but the scarce input is craft labour, rated under talentScarcity.
Buyers are enterprises choosing on switching cost, integration and performance, which the other pillars rate. The name carries reputation, not a price premium it could hold on brand alone.

Growth Score
Q2 2026 revenues $9.56B, +41% YoY (+27% organic), with Electric Infrastructure Solutions revenue +44% and Underground Utility & Infrastructure Solutions +31%. Adjusted EBITDA was ~$1.1B (~11.5% margin vs 9.9% in Q2 2025). Total backlog hit a record $53.4B, up $17.6B YoY. FY26 guidance was raised to $39.3–39.7B revenue and $4.1–4.2B adjusted EBITDA, including $1.2–1.4B of revenue from the Phalcon, Enerfab, Percheron and PSD acquisitions closed in Q2.
Valuation Score
At ~$635 (September 23, 2026 close) — ~20% below the $788.75 52-week high and below the May file's ~$762 — PWR trades at ~38× the raised FY26 adjusted EPS guide ($16.45–16.95) and ~32× forward consensus. Earnings caught up with the stock rather than the other way round: the FY26 guide midpoint rose ~20% (from ~$13.90) after a Q2 adjusted EPS beat of $4.24 and a record $53.4B backlog, so the multiple fell from the ~54× 'record premium' of May. On the reset ladder the price sits just below the $645 base (about 94% of the way from the $470 bear), yielding a valuation score of 66 — fairly valued on consensus, with limited margin of safety.

Growth Analysis
Growth Drivers
Key Risk
If utility capex pulls forward and digests in 2028-29 simultaneously with AI data-centre power moderation, backlog growth pauses and the ~50× multiple compresses sharply — Quanta has shown 30%+ drawdowns on cyclical scares historically and the stock is at a record valuation.
Score Derivation
82.7 base + 2.0 trajectory + 4 margin − 5 risk = 84
Base 82.7 (16–22% CAGR, midpoint 19%) + 2 trajectory (Electric accelerating at +44%; Underground stable, its organic split unsourced) + 4 margin expanding (Q2 adj EBITDA margin ~11.5% vs 9.9%; FY26 guide ~10.5% vs ~10.1% in FY2025) − 5 moderate risk (utility and data-centre capex digestion, same grade as VRT, ETN, TT, GEV and ABB) = 84
Price Scenarios (12–24 Months)
Valuation Multiples
| Forward P/E (FY26 adj) | ~38× |
| Forward P/E (NTM consensus) | ~32× |
| PEG Ratio | ~1.9× |
| Price / Sales (FY26) | ~2.4× |
| Price / FCF (FY26) | ~42× |
The multiple has compressed from ~54× to ~38× current-year EPS without the price collapsing, because guidance kept rising. At ~32× forward the stock trades at a premium to Eaton (~28× FY27) for similar high-teens EPS growth — a premium the $53.4B backlog and self-perform labour moat help justify, but that leaves the stock close to fair value rather than cheap.
Approximate figures as of September 23, 2026 (price ~$635).
Where We Are vs Targets
Loading live price…
AI data-centre power build-out and utility capex digest in 2027–28, book-to-bill slips below 1.0, and the multiple compresses toward an E&C norm while FY27 EPS still grows.
- ~24× FY27 EPS of ~$19.50 (≈$470) — a de-rating from ~32× forward, still above the ~20–22× bear multiples used for Vertiv and Eaton given Quanta's backlog visibility
- Hyperscaler capex growth slows sharply in 2027, delaying data-centre power feed and substation work
- Utility transmission spending digests after the 2025–26 pull-forward; backlog stops growing from the $53.4B record
- Lineman wage inflation and acquisition integration pressure margins
FY26 adjusted EPS lands inside the $16.45–16.95 guide, FY27 grows high-teens toward ~$19.50 on backlog conversion, and the multiple holds a modest premium to electrical peers on visibility.
- ~33× FY27 EPS of ~$19.50 (≈$645), a modest premium to Eaton's ~28× on similar growth, justified by the $53.4B backlog
- Revenue ~$39.5B and adjusted EBITDA $4.1–4.2B in FY26 as guided
- The four Q2 acquisitions (Falcone, Interfab, Percheron, PSD) widen self-perform capacity and geographic reach
- Backlog keeps building with book-to-bill above 1.0 through 2027
The grid super-cycle extends through 2030 as AI power demand compounds; EPS keeps compounding high-teens and the multiple re-expands toward the 2026 highs.
- ~40× FY28 EPS of ~$23 (≈$920) — FY27 ~$19.50 grown ~18% — well above the $788.75 52-week high
- AI data-centre and utility power demand sustain 20%+ growth through 2030
- Utility integrated resource plans formalise multi-decade transmission upgrades
- Quanta keeps consolidating the fragmented specialty-contractor market via accretive M&A
