Quanta Services (PWR) Q3 2026 earnings review
Quanta's backlog hits a record, and its full-year plan rises
Quanta Services, the largest electric grid and energy contractor in the US, grew faster across every part of its business while signing record new orders. Third-quarter revenue rose 57% from a year ago, and profit per share excluding one-offs climbed 82% as operating margins widened in both divisions. Chief executive Duke Austin lifted the full-year outlook for a third straight quarter, and third-quarter free cash flow of $1.2 billion beat what the prior plan implied for the entire second half by our math.
| Revenue | $12.01B +57.4% from a year ago |
|---|---|
| Profit per share, excluding one-offs | $6.06 +82.0% from a year ago |
| Total backlog | $63.7B +62.7% from a year ago |
| Full-year revenue outlook | Raised $1.95B middle of the range: 45.5% growth |
⚖️ Verdict: 🟢 Bullish
The story got better because signed project orders accelerated and the dip in routine utility maintenance estimates reversed. Firm orders due within a year more than doubled from a year ago, while estimated 12-month maintenance orders rebounded 19% from last quarter by our math. One caution: the company closed six acquisitions since April, and the earnings release does not disclose how much of the sales and backlog jump came from bought businesses.
The question now is how much of this step-up is organic demand versus purchased growth, and whether higher fixed-price project exposure brings cost-overrun risk. One view is that utilities and data centers are locking in crew capacity at higher margins; the other is that aggressive deal-making is masking the true underlying growth rate. The acquired-revenue and contract-mix footnotes in the upcoming quarterly filing will settle the first part.
🐂 Bull Case
Contracted Backlog Nearly Doubled From Last Year
Quanta builds and repairs electric grids, power plants and pipelines. The company tracks future work in two ways: total backlog, which includes estimates under multi-year service agreements, and remaining performance obligations (RPO), which count only firm, signed orders. Chief executive Duke Austin said demand is broadening across utility, power generation and technology customers, and "we believe there is opportunity to deliver strong double-digit adjusted EPS growth in 2027, supported by continued backlog growth."
- Total backlog: $63.7 billion, up 62.7% from a year ago and up $10.3 billion from last quarter by our math
- Firm orders (total RPO): $41.8 billion, up 99.1% from a year ago
- Firm orders due within 12 months: $28.0 billion, up 107.9% from a year ago
The numbers support Austin's claim because the firmest part of the order book is growing the fastest. Signed orders due over the next four quarters more than doubled from a year ago, giving the infrastructure contractor unusually high visibility into next year's sales.
What to watch: the backlog breakdown in the quarterly filing. It will show whether the 3-gigawatt NiSource power project entered the order book this quarter as management previously anticipated.
Both Operating Segments Expanded Their Margins Again
Quanta runs two operating divisions: Electric, which builds power lines, substations and generation facilities, and Underground and Infrastructure, which handles gas pipelines, industrial facilities and underground cables. Austin said the company's ability to move its skilled crews across different markets lets it place workers where demand is strongest and deliver more predictable results.
- Operating margin: 8.5% of revenue, up 1.8 percentage points from a year ago by our math
- Cost of services (direct project labor and materials): 83.3% of revenue, down 0.8 percentage points
- Selling, general and administrative overhead: 6.5% of revenue, down 1.0 percentage point
- Electric operating margin: 12.6%, up 1.2 percentage points; Underground: 9.4%, up 1.0 percentage point
Profit grew nearly twice as fast as revenue because both field execution and corporate overhead scaled efficiently. Neither division relied on the other to carry profitability, proving that larger project scale is absorbing fixed costs across the business.
What to watch: fourth-quarter segment operating margins. Holding Underground margins near 9% during winter weather would confirm that the division's profitability has permanently stepped up.
Customer Upfront Payments Lifted Free Cash Flow
Large infrastructure projects often require working capital upfront, but Quanta has been negotiating advance billings from customers before incurring costs. Those upfront payments sit on the balance sheet as contract liabilities. In the third quarter, contract liabilities reached $5.54 billion, up 69.9% from the end of 2025 by our math.
Because customers funded the work early, third-quarter free cash flow nearly tripled from a year ago to $1.20 billion. By our math, that single quarter topped the $1.18 billion middle of the range that the prior full-year outlook implied for the entire second half. In response, the company raised its full-year free cash flow plan by $500 million.
What to watch: fourth-quarter free cash flow, which the raised outlook implies at $230 million to $730 million by our math. Finishing near the top of that range would show that customer advance payments are not reversing.
Multi-Year Maintenance Estimates Stopped Shrinking
Alongside firm project orders, Quanta's backlog includes estimated work under master service agreements (MSAs), which are multi-year contracts for routine utility maintenance. In the first half of 2026, the 12-month MSA estimate shrank by 13.4%, raising concern that the company's recurring base business was contracting.
This quarter argued against that concern. Estimated 12-month MSA orders rebounded 19.2% from last quarter to $10.49 billion by our math, and rose 18.3% from a year ago. Both Electric and Underground MSA estimates grew from the second quarter, showing that utility maintenance work is expanding alongside large project awards rather than being cannibalized by them.
What to watch: 12-month estimated MSA orders at year-end. Another sequential increase in the fourth quarter would settle the concern that recurring utility work is slowing.
🐻 Bear Case
Acquisitions Blur the True Underlying Growth Rate
Quanta is buying companies to "strengthen its front-end, fabrication and supply chain capabilities", adding engineering and equipment manufacturing to its contracting model. In September and October, the Houston-based group bought an energy engineering firm and a steel monopole manufacturer for $245 million in cash and stock. It has now closed five deals in the first nine months of 2026 after buying eight companies in 2025.
- Goodwill on the balance sheet: $8.08 billion, up $764 million since year-end 2025 by our math
- Intangible amortization expense: $188.6 million in Q3, up 41.6% from a year ago
- Earn-out fair-value charge (contingent consideration): $19.8 million in Q3, nearly triple the $6.8 million a year ago
While the two newest deals are "not expected to contribute materially to Quanta’s full-year 2026 financial results", the four large companies bought in the second quarter and July contributed their first full quarter in Q3. Because the release does not separate sales or backlog from businesses owned a year ago, outsiders cannot see how much of the 57.4% revenue jump and $10.3 billion backlog addition was bought rather than won.
What to watch: the acquired-revenue and backlog footnote in the third-quarter 10-Q filing. If bought companies supplied more than half of the year-over-year sales increase, underlying growth is slower than the headline suggests.
Risks this quarter didn't answer
Six standing items from our prior analysis depend on footnote tables or call commentary that are not in the earnings release.
- Fixed-price contract exposure and estimate swings: the quarterly filing's revenue footnote will show whether fixed-price work rose above last quarter's 63.7% share and whether project estimate revisions moved margins.
- Technology and data-center share of sales: not quantified in the release; call remarks or the filing will show if it moved above the prior 15% to 20% range.
- NiSource power generation and 765-kilovolt transmission awards: the release does not state how much of these flagship programs entered the $63.7 billion backlog.
- Skilled craft labor hiring and training drag: the release mentions the 2025 Sustainability Report on workforce training but gives no headcount or cost figures.
- Data-center permitting and state moratoria: no update beyond standard cautionary language; call Q&A is the next check on local siting delays.
💲 Other KPIs
Uncollected customer bills rose 59.6% from a year ago by our math, tracking right in line with the 57.4% jump in third-quarter sales. Because receivables grew no faster than revenue while upfront customer advances surged, working capital generated cash rather than tying it up.
Total debt minus cash fell by $923 million from last quarter by our math, as strong free cash flow built the cash balance to $2.32 billion. During the quarter, the contractor issued $2.00 billion of senior notes and paid off its $618.8 million term loan early.
The average number of diluted shares rose 0.8% from a year ago and edged up slightly from 152.4 million last quarter. Quanta issued approximately $149 million of common stock to help pay for its two autumn acquisitions and reported no share buybacks in the release.
🔮 Guidance
Raised. The middle of the full-year sales plan moved up $1.95 billion, to 45.5% growth for the year by our math. That leaves about $12.0 billion of revenue for the fourth quarter, or 53.1% growth from a year ago — slightly below the third quarter's 57.4% pace. It is the third raise this year: +$1.45B in Q1, +$4.55B in Q2, and +$1.95B now.
Raised. The middle of the range rose $1.40, pointing to 68.4% full-year growth by our math. That implies $5.12 per share for the fourth quarter, up 62.0% from a year ago. Management raised this target in all three quarters of 2026: +$0.90, +$2.80, and +$1.40.
Raised. The middle of the range increased by $1.105 to $12.77, or 87.8% growth for the year by our math. After $8.97 in the first nine months, the plan leaves $3.80 for the fourth quarter, up 82.7% from a year ago despite higher acquisition amortization.
Raised. Using the reconciliation table's exact range of $1,917.0 million to $1,978.3 million, the middle moved up $169 million to 89.4% full-year growth by our math. That leaves $580.8 million for the fourth quarter, up 84.1% from a year ago.
Raised. The middle of the range rose $296 million to $4.45 billion, or 54.6% growth for the year by our math. That implies $1.24 billion in the fourth quarter, up 47.1% from a year ago. Sequence of raises this year: +$150M, +$580M, and +$296M.
Raised. The middle of the range climbed $239 million to $4.04 billion, representing 57.8% full-year growth by our math. That leaves $1.16 billion for the fourth quarter, up 55.0% from a year ago.
Raised. The outlook moved up $500 million to a middle of $2.75 billion, or 64.4% full-year growth by our math. With $2.27 billion already collected in the first nine months, the plan implies $480 million in the fourth quarter — down 49.3% from last year's fourth quarter, leaving a low bar if advance billings hold.
Raised. The middle of the range rose $575 million to $3.73 billion, up 67.0% for the year by our math. After $2.94 billion in the first nine months, the plan leaves $784 million for the fourth quarter, down 30.5% from a year ago.
Raised. Planned capital spending increased by $75 million at the middle of the range to $975 million, following a $125 million increase last quarter. With $671 million spent in the first nine months, the plan leaves $304 million for the fourth quarter as Quanta builds out its equipment and manufacturing facilities.
❓ Key Questions
How much of Q3 revenue and backlog came from acquisitions?
Quanta closed four large acquisitions in the second quarter and July, plus two more in September and October. Without the organic split from the 10-Q filing, investors cannot tell how much of the 57.4% sales jump and $10.3 billion backlog addition came from existing operations.
Did the 3-gigawatt NiSource power project enter Q3 backlog?
Last quarter, management expected a large portion of the NiSource power generation program to enter backlog in the third quarter. Firm Electric orders rose by $8.2 billion, and confirming whether NiSource drove that jump will clarify how much power plant work is now under contract.
Why does the Q4 plan imply free cash flow halving?
After generating $1.20 billion of free cash flow in the third quarter alone, the raised full-year outlook implies only $480 million at the middle of the range for the fourth quarter. Management should clarify whether customer advance payments will reverse before year-end.
What share of revenue now comes from data-center customers?
Chief executive Duke Austin highlighted broadening demand from technology customers, which accounted for 15% to 20% of the business last quarter. Updating that figure and its margin profile would show how dependent Quanta's margin expansion is on data-center buildouts.
