The unit is one deployed craft worker. In 2025 each year-end employee carried about $410k of revenue, $61.5k of gross profit and $23k of operating income, against $272k, $36k and $11k in 2016. Profit per worker has grown because the work has moved to larger, more complex and more often fixed-price jobs, not because Quanta charges a markup on materials.
| What it is | The largest US specialty contractor for the electric grid, power generation and large-load sites, plus a smaller gas-utility, pipeline and industrial arm. |
|---|---|
| How it makes money | Paid per unit installed, cost plus a margin, or a lump sum for labor, equipment and project management on assets the customer owns. |
| What protects it | Journeyman labor and the training to grow it, preferred-provider status with utilities, and the balance sheet to bond ($21.5bn of performance bonds) and staff decade-long programs. |
| What drives earnings | Utility grid capex and load growth; mix toward large fixed-price, EPC and data-center work; acquisitions ($9.3bn of cash in 2016–2025). |
| Cycle exposure | Medium. Regulated utility work is recurring; project work swings. Today: record backlog and record margins. |
Utilities building new high-voltage lines, hyperscalers needing substations and data-hall electrical work, and gas utilities replacing old mains all need large numbers of certified craft workers, specialised equipment and crews that can move fast. Few owners keep that capacity in-house for peak programs. Quanta sells it through dozens of decentralized operating companies. At year-end 2025 it had about 69,500 employees, 55,700 of them hourly, and “more than 85,000” after the mid-2026 acquisitions. Customers usually supply most materials, so Quanta’s value-add is labor, equipment, engineering and the willingness to carry execution risk.
A unit of work moves from award to cash in four steps: an MSA, alliance or project award; field work recognised by units completed or, for 63.8% of 2025 revenue, by cost-to-cost progress; milestone or periodic billing; then collection, at 60 days DSO at year-end 2025 against a 75-day five-year average. Disputed scope sits in change orders. Quanta carried $983.6m of unapproved change orders and claims at year-end 2025, mostly on one Canadian transmission project. Its approval in 2026 cut the balance to $411.1m.
Electric (81% of 2025 revenue, 10.3% segment margin) spans transmission, distribution, substations, renewable and gas generation EPC, storm restoration and inside-the-fence data-center electrical work. It also carries the 50% LUMA venture that runs Puerto Rico’s grid, plus transformer and breaker manufacturing. Underground and Infrastructure (19%, 7.3%) covers gas utility, pipeline integrity, industrial services, civil site work and mechanical systems for large load centers. The more important shift is in how Quanta is paid. Fixed-price work rose from 49% to 61% of revenue between 2023 and 2025, and MSAs fell from 65% of backlog in 2022 to 41% by mid-2026. Quanta is moving from supplying recurring utility crews to building large projects, accepting more performance risk for higher margins. Along the way it exited oil-linked operations, a Peru telecom project and Latin America, and Canada fell from 9.8% to 3.6% of revenue.
Utilities own the grid and earn a regulated return for decades on what they spend. That spending sets the size of the pool. Investor-owned utility capex was $178.2bn in 2024 and is projected at $207.9bn in 2025 and $248.4bn in 2029, about half of it T&D (outside: EEI). Contractors earn a one-time margin on labor, and only while crews are working. Equipment makers currently hold real scarcity. Power transformer lead times average about 128 weeks and roughly 80% of supply is imported (outside: Wood Mackenzie), which is why Quanta now builds transformers and breakers itself.
Contracting is fragmented and local. MSAs are regional, and Quanta itself admits to low entry barriers in some lines:
The barriers that do bind are qualified labor, bonding capacity for large jobs, and safety-based qualification. Quanta leads its peers on scale and margin:
| FY2025 segment | Revenue | Margin measure | Margin |
|---|---|---|---|
| Quanta Electric | $23.00bn | Segment operating | 10.3% |
| MasTec Power Delivery | $4.18bn | Segment EBITDA | 8.1% |
| Primoris Utilities | $2.69bn | Gross | 11.5% |
| MYR Group T&D | $2.00bn | Segment operating | 7.9% |
Outside evidence only partly supports the company’s story. The “largest provider” claim holds: Electric is about 5.5x MasTec Power Delivery. Labor scarcity is real, with median lineman pay up about 4.7% a year from $72,520 (2019) to $95,320 (2025), but supply responds. Contractor-employed linemen grew 21.4% from 2019 to 2023, and union hiring halls give rivals the same pool. Outsourcing is rising: contractors employed 30.2% of linemen in 2023, up from 25.9% in 2014 (outside: BLS OEWS). Even so, MSAs are non-exclusive and re-bid, and price is “often a principal factor” (outside: MasTec). What a rival could not copy quickly is the combination: roughly 69,500 people, a lineman college and training budget of about $250m a year, energized-work methods, helicopters, and the balance sheet to run several 765 kV programs at once.
The winners in this industry have the most trained, safe crews and the estimating discipline to take fixed-price risk without blow-ups. MYR’s T&D margin fell to 3.7% in 2024, showing how quickly that discipline can lapse. Quanta clearly passes the first two tests. The third is open, with fixed-price work now 61% of revenue. Data-center electrical is the most contested arena: EMCOR paid about 10.8x EBITDA for Miller Electric and Dycom $1.95bn for Power Solutions (outside: EMCOR 8-K; Dycom 10-K).
Revenue compounded at 15.7% from $7.65bn (2016) to $28.48bn (2025). Quanta reports no organic rate, but it does disclose revenue from acquired businesses, which allows an approximation. Nearly 60% of 2025’s growth was bought. In 2026 organic growth accelerated sharply. Guidance is now $39.3–39.7bn of revenue and $16.45–16.95 of adjusted EPS, including $1.2–1.4bn from businesses bought in Q2 and July 2026.
| Period | Reported | From acquisitions | Organic (approx.) |
|---|---|---|---|
| 2024 vs 2023 | +13.4% | ~$1.76bn | ~+5.0% |
| 2025 vs 2024 | +20.3% | ~$2.80bn | ~+8.5% |
| Q2 2026 vs Q2 2025 | +41.1% | ~$0.93bn | ~+27.4% |
| H1 2026 vs H1 2025 | +34.0% | ~$1.73bn | ~+20.7% |
About 70% of revenue. Management says the large 765/500/345 kV and generation programs are mostly not yet in backlog and reach the field from about 2H 2027. That is a claim not yet visible in the numbers, and NERC confirms construction “has yet to increase substantially” (outside).
$9.3bn of cash in 2016–2025, more than capex and buybacks combined, plus about $1.24bn upfront in Q2 and July 2026.
Rose from 6% of revenue (2023) to 13% (2025) and 15–20% by mid-2026 per the CEO, built on Cupertino Electric and Dynamic Systems. It depends on hyperscaler budgets, which can be cut faster than utility rate-base plans.
Transformers, breakers, poles and right-of-way services, packaged so Quanta wins more of each customer’s program budget.
Renewables were 33% of 2024 revenue and depend on tax credits. Gas plants are taken only on acceptable terms; the NiSource 3 GW award is the first large test.
Storm work is higher-margin but lumpy. Large-pipeline revenue has “declined significantly” since the shale build-out.
Cost of services is 85% of revenue, mostly wages, subcontractors, materials and equipment. Margin is therefore a matter of crew utilization and job mix, not markup. Fuller crews absorb fixed equipment and overhead costs, which is why U&I margin rose from 5.7% to 7.3% in 2025. Large high-voltage, complex data-center and storm work earns more. Subcontracted work (15–20%) and procured materials earn less. Management puts the Electric range at 10–12%, with 12% reached only at full utilization on stacked large projects. Hiring about 15,500 people in a year, half of them organically, drags on productivity while they train.
| 2016 | 2019 | 2022 | 2025 | |
|---|---|---|---|---|
| Revenue ($bn) | 7.65 | 12.11 | 17.07 | 28.48 |
| Gross margin | 13.3% | 13.2% | 14.8% | 15.0% |
| Operating margin (GAAP) | 4.2% | 4.6% | 5.1% | 5.7% |
| Diluted EPS, GAAP ($) | 1.26 | 2.73 | 3.32 | 6.80 |
| Operating cash flow ($bn) | 0.38 | 0.53 | 1.13 | 2.23 |
| Total backlog ($bn) | 9.75 | 15.00 | 24.09 | 43.98 |
The GAAP-to-adjusted gap ($6.80 against $10.75 EPS in 2025) is mostly acquisition amortization, stock compensation and deal costs. It will widen as long as the deal pace continues. Cash conversion is strong. Operating cash flow was $2.23bn in 2025 and $1.49bn in H1 2026, helped by the Canadian claim settlement and favorable EPC billing terms. The target is free cash flow of 55–60% of adjusted EBITDA. Capex rises to $750–800m in 2026, including $250–350m for manufacturing.
Where the decade’s cash went: about $10.4bn of operating cash flow funded roughly $9.3bn of acquisitions, $3.7bn of capex, $1.1bn of buybacks and $0.3bn of dividends. Debt filled the gap, rising from $0.36bn (2016) to $6.10bn by mid-2026, followed by $2.0bn of new notes in August 2026. Share count has held at about 145–151m since 2019 because deal stock offsets buybacks. Acquisitions are the default use of capital, and buybacks are the hurdle deals are measured against.
Quanta contains two cycles. Regulated utility maintenance and upgrade work is resilient: total utility capex fell only about 10% in 2008–2010, recovered by 2012, and rose in 2020 (outside: EEI). Project work swings. In the 2014–2016 oil downturn revenue stalled near $7.6bn and operating margin hit 3.1% in 2015. Today Quanta is at or near a peak on backlog, gross margin and operating margin. The downside would arrive through the project layers. Grid Strategies judges data-center load forecasts overstated by about 25 GW, wind and solar credits end for projects placed in service after 2027 unless construction began by 4 July 2026, and residential power prices are forecast to rise from 17.3¢ to 18.7¢/kWh by 2027 (outside). Each would leave crews waiting and dilute absorption.
Large transmission is lagging: 41,000 miles are in development but construction has barely risen, and sources conflict on 2024 345 kV+ completions (322 against a revised 888 miles), both far below the roughly 5,000 a year needed (outside: NERC, Grid Strategies). Labor is the binding input. A journeyman takes about four years, and Quanta adds roughly 5,000–7,000 people a year organically.
