Is Dycom's 13.4% EBITDA Margin Set for Another Profitability Lift?

Dycom Industries, Inc. DY is showing encouraging signs of sustained profitability improvement as strong demand for digital infrastructure drives operating leverage across its business. In fiscal 2027 first-quarter results, adjusted EBITDA surged 74.6% year over year to $262.5 million, while the adjusted EBITDA margin expanded 141 basis points (bps) to 13.4%. The improvement came despite continued investments in workforce and footprint expansion.

The Communications segment remained a key contributor, generating $1.57 billion in revenues, up 24.7% organically, while adjusted EBITDA increased 28% to $192.4 million. Its margin reached 12.3%, up 31 bps year over year, supported by operating leverage as fiber-to-the-home and other multiyear infrastructure programs ramped. The Building Systems segment provided an even stronger catalyst for profitability. The segment generated $395.4 million in revenues and achieved a 17.7% adjusted EBITDA margin, with Power Solutions' performance exceeding initial expectations. Management now expects Building Systems to maintain margins in the high teens throughout fiscal 2027.

DY also expects modest margin improvement in Communications as operating leverage offsets investments needed to support growth. Strategic acquisitions could further strengthen profitability by expanding capabilities and creating cross-selling opportunities. The pending $275 million acquisition of National Technology Integrators is expected to add approximately $175 million in annual revenues at mid-to-high-teen historical EBITDA margins.

With record backlog, strong fiber and data center demand, disciplined project selection and continued operating leverage, Dycom appears positioned for further profitability gains. However, the company must execute effectively while scaling its workforce and integrating acquisitions to sustain the margin trajectory.

Dycom vs. EMCOR & Quanta: Who Has the Margin Edge?

Dycom is well-positioned to benefit from accelerating AI, data center and digital infrastructure spending, alongside other market players, including EMCOR Group, Inc. EME and Quanta Services, Inc. PWR.

DY combines fiber-to-the-home, long-haul and middle-mile demand with expanding data center capabilities, while its $11.9 billion backlog, up 46.5% year over year, provides strong visibility. EMCOR benefits from robust data center-related electrical and mechanical construction demand, with RPOs reaching a record $17.14 billion in June 2026. Quanta offers broader exposure to power and utility infrastructure supporting rising electricity demand, with second-quarter 2026 backlog reaching $53.4 billion and RPOs $33.6 billion.

Overall, Dycom's fiber concentration and improving profitability provide an attractive growth profile alongside its larger diversified peers, EMCOR and Quanta.
