EMCOR (EME) Q3 2026 earnings review
EMCOR's backlog hits $18.6 billion, while mechanical margins slip
EMCOR, the electrical and mechanical construction contractor, is growing faster as data center builders order more power and cooling systems. Sales from businesses owned a year ago rose 26%, while contracted backlog jumped 47% to $18.6 billion. Chief executive Tony Guzzi raised the full-year outlook for a third time, and by our math the plan points to 21% revenue growth in the fourth quarter.
| Sales from businesses owned a year ago | +25.5% total revenue $5.54B (+28.8% from a year ago) |
|---|---|
| Profit per share, excluding one-offs | $9.60 +46.1% from a year ago (reported: $9.04, +37.6%) |
| Remaining performance obligations (backlog) | $18.57B +47.2% from a year ago |
| Full-year revenue outlook | Raised $550M middle of the range: $20.8B (+22.5%) |
⚖️ Verdict: 🟢 Bullish
The story got better because the first-half cash shortfall reversed and the newly bought electrical contractors are already lifting sales. Third-quarter operating cash flow reached $797 million by our math, and electrical margins expanded by 2 percentage points. One caution: mechanical construction margins slipped again, and the company took an unexplained $34 million write-off on intangible assets.
The question now is whether the $18.6 billion backlog will turn into revenue at its historical pace or stretch out over multiple years as data center projects grow more complex. If conversion holds steady, sales growth stays above 20% next year; if timelines lengthen, growth slows despite record orders. The third-quarter 10-Q backlog table and February's 2027 outlook will settle it.
🐂 Bull Case
Contract Backlog Reaches $18.6 Billion on Data Centers
EMCOR tracks its contracted backlog through remaining performance obligations (RPOs), the value of signed customer contracts it has not yet completed. That backlog drives future sales, but critics worry that heavy reliance on data center builders leaves the contractor exposed if tech companies pause spending. In the third quarter, total RPOs climbed 47.2% from a year ago to $18.57 billion, adding $1.43 billion since June by our math.
The company said the largest gains came from Network and Communications, its segment serving data centers, as "mission critical facilities continue to require substantial electrical infrastructure and increasingly sophisticated cooling systems". Healthcare, water, institutional and industrial projects also added to the backlog. Sales from businesses owned a year ago accelerated to 25.5% growth, so the backlog is turning into revenue faster while broadening across industries.
What to watch: the share of RPOs scheduled to convert into revenue within 12 months in the quarterly filing. A drop below last quarter's 75% to 76% range would mean larger projects are taking longer to start.
Electrical Margins and Lower Overhead Lift Profit
"Our strong revenue growth, coupled with excellent field execution and improved SG&A leverage, resulted in meaningful expansion of our operating margin," chief executive Tony Guzzi said. Last year, electrical margins dipped when EMCOR spent money hiring workers in new regions and absorbing the Miller Electric acquisition.
- US electrical construction operating margin: 13.3%, up 2.0 percentage points from a year ago
- Selling, general and administrative overhead: 9.5% of revenue, down 0.5 percentage points
- Gross margin (profit after direct job costs): 20.0%, up 0.6 percentage points by our math
- Operating margin excluding one-offs: 10.5%, up 1.1 percentage points from 9.4%
Guzzi's claim holds up against the numbers because both field profitability and office overhead improved at the same time. Even including a $34.0 million write-off on intangible assets, reported operating margin rose 0.4 percentage points to 9.8%. The company also raised its full-year operating margin plan excluding one-offs to about 10%.
What to watch: fourth-quarter electrical operating margin in the year-end report. Holding above 13% would confirm that the newly acquired electrical contractors are not diluting segment profitability.
Electrical Acquisitions Closed and Added $313 Million
EMCOR agreed last quarter to buy five electrical contractors for about $750 million upfront to expand its data center workforce. The cash flow statement shows the company paid $702 million for acquisitions in the third quarter by our math, bringing nine-month buyout spending to $797.4 million.
Those deals immediately lifted the top line, as revenue from acquired businesses jumped to $313.3 million in the quarter from $169.2 million in the second quarter. That already exceeds the $250 million to $275 million second-half target management had baked into its prior plan, which explains a large part of the full-year revenue raise.
What to watch: fourth-quarter acquisition revenue in the full-year reconciliation table. A reading above $150 million would show the five new contractors are running ahead of their $625 million pre-deal annual pace.
Cash Flow Rebounded With $797 Million in Q3
In the first half of 2026, operating cash flow trailed last year because fast project growth tied up money in unpaid customer bills. Management maintained that full-year cash flow would still match net income, and the third quarter backed up that view.
By our math, EMCOR generated $796.7 million of operating cash flow in the third quarter alone, lifting the nine-month total to $1.09 billion vs $777.7 million a year ago. Nine-month operating cash flow reached 98% of reported net income, up from 41% at the halfway mark, because advance customer payments (contract liabilities) rose $359 million during the quarter.
What to watch: full-year operating cash flow against full-year operating income in February. Reaching 80% to 85% of operating income would retire the working-capital concern for the year.
🐻 Bear Case
Mechanical Margins Fall and Intangibles Take a Hit
Guzzi praised "excellent field execution" across the business, and US mechanical construction — which installs heating, cooling and piping systems — grew sales 43.1% to $2.55 billion. Yet the segment's operating margin fell for a fourth straight quarter against prior-year levels, dropping 0.8 percentage points to 12.1%.
The company also recorded a "non-cash impairment loss on identifiable intangible assets of $34.0 million" in the quarter, which it excluded from its preferred profit numbers. The release did not name which acquired business lost value. Together, the lower mechanical margin and the write-off show that rapid expansion and past buyouts carry hidden cost pressures.
What to watch: the footnote explaining the $34 million intangible write-off in the third-quarter 10-Q filing. It will reveal whether a recent construction acquisition fell short of its contract targets.
Industrial Profit Shrank Ahead of Refiner Slowdown
EMCOR's US industrial services unit performs maintenance and turnarounds for oil refineries and petrochemical plants. Management warned last quarter that Middle East supply conditions would cause refiners to delay maintenance in the second half of the year.
That slowdown showed up in the third quarter, as industrial revenue stayed flat at $287.5 million (up 0.2% from a year ago) after growing 25.9% in the second quarter. Segment operating profit fell 18.6% to $5.1 million, cutting its operating margin from 2.2% to 1.8%, so the energy services business is once again dragging on consolidated returns.
What to watch: fourth-quarter industrial services operating income. A drop into a loss during the peak autumn maintenance season would confirm that refinery customers have pushed work into 2027.
Risks this quarter didn't answer
Four standing concerns from prior quarters cannot be measured from the earnings release alone and await the quarterly filing or conference call.
- Backlog duration: the release does not split RPOs into work due within 12 months versus later years; Note 3 of the 10-Q will show if project timelines stretched further.
- Data center share of sales and backlog: the release gives no dollar figures for Network and Communications; the 10-Q segment tables will show if concentration passed 35% of sales.
- Field supervision bottleneck: Guzzi highlighted "foremen, superintendents, project managers" qualitatively, but the release provides no headcount or labor retention metrics.
- Local power and permitting delays: listed only as a standard risk factor; call commentary is needed to see if grid limits delayed any data center starts.

Board Adds $500 Million to Share Buyback Plan
EMCOR spent $188.0 million buying back its own stock in the third quarter by our math, bringing nine-month repurchases to $456.5 million and reducing its diluted share count by 1.6% from a year ago. The board approved an additional $500 million for future buybacks, which the contractor will fund from operations alongside its $797.4 million of year-to-date acquisition spending.
💲 Other KPIs
Up 38.5% from a year ago and 13.8% from June, outpacing the 28.8% rise in quarterly revenue. Contract liabilities are advance payments from customers for work not yet performed, so their growth funds project costs upfront and drove the third-quarter cash flow rebound.
Unpaid customer bills rose 34.7% from a year ago and 30.4% since the end of 2025, running ahead of revenue growth. The $1.29 billion increase since December absorbed cash during the first half, though faster customer advances in the third quarter more than offset the billing buildup.
Sales in the commercial building maintenance unit grew 4.7% from a year ago, following 5.6% growth in the second quarter and 4.0% in the first. Operating margin expanded by 0.5 percentage points to 7.8%, extending the division's turnaround after its 2025 reorganization.
🔮 Guidance
Raised. The middle of the range moved up $550 million to $20.8 billion, or 22.5% growth for the year. By our math, that leaves $5.48 billion for the fourth quarter, up 21.3% from a year ago (or 23.9% excluding the sold UK unit). This is the third raise this year: +$750M in Q1, +$1,375M in Q2, and +$550M in Q3.
Raised. The middle of the range rose $2.38 to $35.00 per share, or 35.3% growth over last year's profit excluding one-offs. By our math, that leaves $9.52 per share for the fourth quarter, up 32.4% from a year ago when excluding last year's UK sale gain. It is the third raise this year: +$0.75, +$3.63, and +$2.38.
Raised. The full-year target moved up by about 0.35 percentage points to roughly 10%, up from 9.4% in 2025. With nine-month margin already at 10.0% excluding the intangible write-off, the plan points to about 10.0% in the fourth quarter by our math, down from 10.5% in the third quarter.
❓ Key Questions
Which business caused the $34 million intangible write-off?
EMCOR booked a $34.0 million non-cash impairment on identifiable intangible assets in the third quarter and excluded it from adjusted profit. Knowing which acquired contractor missed projections will show whether past buyouts are struggling.
What share of the $18.6B backlog converts within 12 months?
The portion of RPOs burning inside one year fell from about 85% historically to 75%–76% last quarter as data center projects grew larger. The 10-Q table will show if conversion slowed further.
How big is Network and Communications in sales and backlog?
Data center work reached 34.4% of revenue in the second quarter, and the release named it the top backlog driver again. Disclosing the exact dollar share will show how concentrated EMCOR's risk has become.
Did Schmidt Electric and Connelly Electric both close in Q3?
Cash paid for acquisitions jumped by $702 million in the quarter and acquisition revenue hit $313 million. Management should confirm that all five electrical deals are now closed and state their expected fourth-quarter contribution.
