Its latest results show why the opportunity is credible: fiscal 2027 second-quarter contract revenue reached $2.006 billion, up 45.6% from the prior-year quarter, while backlog hit a record $12.242 billion. Yet Communications, the larger segment, delivered a 13.6% Adjusted EBITDA margin, down 134 basis points year over year. Building Systems produced a much higher 24.5% margin, but that quarter included project-specific benefits that should not be treated as a permanent run rate.
The practical conclusion for investors is qualified: Dycom has real exposure to the physical buildout needed by cloud and AI workloads, and organic growth remains substantial. The key question is whether the company can convert that demand into durable margins while managing customer concentration, project timing, acquisitions and operating costs.

What Dycom actually does—and where AI fits
Dycom sells specialty contracting services for communications networks and critical facilities. Its Communications segment covers program management, planning, engineering and design, aerial and underground construction, wireless construction, maintenance, fulfillment and utility locating. These services help telecom operators deploy and maintain fiber, wireless and other network infrastructure.
Its Building Systems segment provides electrical, energy-management, security and fire-safety systems for data centers and other critical facilities. Those capabilities connect Dycom to the physical side of cloud and AI expansion: more computing demand requires more data-center capacity, power distribution, cabling, cooling-related infrastructure and security systems.
#1 Best Overall
That is an infrastructure connection, not a reported AI product or AI revenue stream. Dycom’s filings describe fiber infrastructure and data-center building systems as demand drivers associated with cloud and AI growth, but they do not disclose a standalone percentage of revenue generated by AI projects. Investors should therefore avoid treating all of Dycom’s growth as AI-derived.
The company expanded its data-center electrical presence in the Washington, D.C., Maryland and Virginia region through the Power Solutions acquisition completed on December 23, 2025. In fiscal 2027’s second quarter, Dycom also acquired National Technology Integrators, which adds inside-plant structured cabling, audiovisual and security systems. Management presents these additions as ways to broaden its data-center and critical-facility capabilities; the financial statements still combine demand from many communications and building projects.
Fiscal 2027 second-quarter results at a glance
Dycom’s latest reported quarter ended August 1, 2026, and the company released results on August 26, 2026. The consolidated figures were:

Adjusted EBITDA is a non-GAAP measure that Dycom uses to discuss operating performance before interest, taxes, depreciation and amortization, with the company’s specified adjustments. The 15.7% figure is consolidated; it is not the margin of either reportable segment.
Management described the first half as delivering record organic revenue, increased profitability and above-market growth. That statement is management’s characterization, not an independent measurement of the broader infrastructure market.

Total growth is impressive, but organic growth tells the cleaner story
The 45.6% increase in contract revenue includes acquired operations and other changes in the company’s footprint. Organic growth was 16.7%, so the difference between the two rates is material. Acquisitions are contributing meaningfully to reported expansion, and investors should separate purchased revenue from growth generated by the pre-existing business.
For fiscal 2026, Dycom reported $5.546 billion of contract revenue, up 17.9% overall and 6.5% organically. Fiscal 2026 included the results of Power Solutions after its December 23, 2025 acquisition. Those figures provide a useful baseline, but they are not perfectly comparable with earlier periods.
Recommended Free Tools
- Fiscal 2026 had 53 weeks, compared with 52 weeks in fiscal 2025.
- Dycom changed its segment presentation in the fourth quarter of fiscal 2026, moving from one reportable segment to Communications and Building Systems.
- Fiscal 2027 comparisons include acquired businesses, including National Technology Integrators in the second quarter.
When evaluating growth, use organic revenue, acquisition contribution and the number of weeks in each fiscal year together. A large reported increase can be economically attractive while still requiring more work to determine the underlying pace.
The margin mix is the central issue
Dycom’s two reportable segments have different work mixes, cost structures and project timing. Comparing their quarterly margins without that context can lead to an incorrect conclusion about the company’s normalized profitability.
| Segment | Fiscal 2027 Q2 revenue | Margin or growth detail | What management reported |
|---|---|---|---|
| Communications | $1.608 billion | 16.7% organic revenue growth; 13.6% Adjusted EBITDA margin | Margin down 134 basis points from 14.9% in the prior-year quarter |
| Building Systems | $397.5 million | 24.5% Adjusted EBITDA margin | Benefit from execution, operating leverage and favorable changes in project cost estimates and scope |
Communications is much larger by revenue, so its margin carries more weight in the consolidated result. Its 13.6% margin was below the 14.9% reported in the comparable quarter. Management cited spending to scale operations, operating-leverage effects from wireless projects deferred into the next fiscal year and higher year-over-year fuel prices.
Building Systems posted the stronger 24.5% margin. The release attributed that result partly to favorable changes in cost estimates and scope of services on projects. Such changes can improve a specific quarter without establishing a repeatable long-term margin. The 24.5% result is therefore evidence of earning power in the segment, not a guaranteed steady-state rate.
Why Communications margins are under pressure
Scaling costs arrive before all revenue
Management is investing to expand operating capacity. Hiring, supervision, equipment, systems and other overhead can be incurred before the related projects reach full production. That creates operating deleverage in the short term: revenue can grow while the incremental margin is lower.
Wireless work shifted into a later fiscal year
Approximately $150 million of wireless program revenue moved from fiscal 2027 into fiscal 2028, according to management, while the overall program scope remained unchanged. The deferral changes quarterly timing and can reduce the leverage expected from the Communications cost base in fiscal 2027. It does not mean the company canceled that work, but it does make the reported year more dependent on other projects.
Fuel and field execution matter
Higher fuel prices directly affect fleets and field operations. Weather, labor availability, materials, equipment utilization and project execution can also move margins from quarter to quarter. Communications work is performed across many locations and customer programs, so a strong backlog does not eliminate operating variability.
Management expects a slight year-over-year decline in Communications Adjusted EBITDA margin for fiscal 2027. That outlook is more cautious than the revenue trajectory and is the clearest reason to watch mix and execution rather than revenue alone.
Rank #4
Building Systems can lift the mix, but do not extrapolate one quarter
Building Systems’ 24.5% second-quarter Adjusted EBITDA margin was well above Communications’ 13.6%. A greater share of Building Systems revenue could raise consolidated margins if the segment sustains its performance. However, several qualifications matter.
- The segment’s quarterly result reflected favorable project cost-estimate and scope changes identified by the company.
- Project timing and completion stages can make a single quarter unusually strong or weak.
- Management expects Building Systems margins in the high-teens to low-twenties as a percentage of segment revenue for the remainder of fiscal 2027, below the 24.5% second-quarter figure.
The outlook implies that management itself does not regard the second-quarter percentage as the expected ongoing rate. Investors should use the guided range for forward analysis and treat the quarter’s 24.5% as a data point requiring normalization.
Revenue outlook and backlog: strong visibility, not guaranteed earnings
Dycom raised its fiscal 2027 contract-revenue outlook to $7.48 billion–$7.66 billion. The range incorporates the wireless timing change and the company’s current expectations for its programs. Management said the approximately $150 million of deferred wireless revenue moved into fiscal 2028 without changing total program scope.
Backlog reached $12.242 billion at the end of the second quarter, up 53.2% year over year. Backlog indicates contracted or expected work under the company’s arrangements, but it is not the same as recognized revenue, cash flow or profit. Projects can be rescheduled, repriced, terminated or executed at different margins.

Customer concentration raises the stakes
Three customers represented substantial portions of fiscal 2026 contract revenue: AT&T accounted for 25.4%, Verizon for 14.0% and Lumen for 10.8%. The concentration means decisions by a relatively small group of telecom customers can materially affect Dycom’s workload, pricing, capital programs and payment timing.
Large customers can provide valuable scale and recurring programs, but they also have negotiating power. The annual filing notes that customer spending and contract relationships may change. A reduction, delay or rebidding of work by one major customer could affect revenue and utilization even if industry demand remains healthy.
How to analyze Dycom from here
- Start with organic revenue growth. Compare total growth with organic growth to identify how much expansion comes from acquisitions.
- Track Communications margin separately. This is the larger segment and management expects a slight fiscal 2027 decline. Look for evidence that scaling investments are producing later operating leverage.
- Normalize Building Systems. Compare quarterly results with management’s high-teens to low-twenties outlook rather than assuming the 24.5% quarter repeats.
- Measure backlog conversion. Follow how quickly the $12.242 billion backlog becomes revenue and whether the associated margins meet expectations.
- Watch wireless timing. The $150 million deferral into fiscal 2028 can make fiscal 2027 quarterly comparisons uneven.
- Review customer exposure. Monitor spending plans and contract renewals for the three customers that supplied most fiscal 2026 revenue.
- Check cash generation and acquisitions. Fiscal 2026 free cash flow was $435.3 million, but future cash conversion will depend on working capital, project timing, capital spending and integration of acquired operations.
What could derail the growth thesis?
- Margin dilution: Communications could remain below prior-year margins if scaling costs, fuel or delayed wireless work outweigh operating leverage.
- Project execution: Labor shortages, equipment constraints, materials inflation, adverse weather or inaccurate estimates can reduce profitability.
- Customer changes: Major telecom customers may reduce spending, terminate work or rebid contracts.
- Acquisition integration: Purchased revenue may not translate into expected margins or cross-selling benefits.
- Backlog quality: A large backlog can contain projects with different start dates, terms and economics; it does not assure revenue or earnings.
- Comparability: The 53-week fiscal 2026, segment reclassification and acquisitions can make simple year-over-year percentages misleading.
Bottom line for investors
Dycom’s reported numbers support a genuine infrastructure-demand story tied to fiber, wireless networks and data-center construction. Fiscal 2027 second-quarter organic growth of 16.7%, a $12.242 billion backlog and a raised $7.48 billion–$7.66 billion revenue outlook show substantial activity. The company’s exposure to AI is indirect: it supplies physical connectivity and facility systems rather than AI products, and no AI-specific revenue share is disclosed.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
The caution is the margin mix. Communications generated most of the quarter’s revenue but saw its Adjusted EBITDA margin fall to 13.6%, while Building Systems’ 24.5% margin benefited from project-specific factors and is expected to settle in the high-teens to low-twenties range for the rest of fiscal 2027. The investment case therefore depends on whether backlog converts on acceptable terms, deferred wireless work arrives as planned and operating investments eventually improve—not erode—Communications profitability.
