EMCOR and MasTec are both benefiting from strong demand in data centers and infrastructure projects. EMCOR shows stronger execution with a record $17.14B RPO (up 43.9% YoY) and superior ROE of 35.49%, supported by strategic electrical contractor acquisitions.

MasTec has a growing $21.4B backlog and the Superior Group acquisition, but faces headwinds from weakening Communications segment profitability and downward earnings revisions. Both stocks carry a Zacks Rank #4 (Sell), though EMCOR appears more attractive due to stable earnings estimates and better operational efficiency.

MasTec is expected to report Q3 2026 earnings of $2.94 per share (up 18.6% YoY) and revenues of $4.94 billion (up 24.6% YoY) on October 29. However, the company carries a negative Earnings ESP of -0.51% and a Zacks Rank #4, making it difficult to predict an earnings beat. While MasTec has beaten consensus estimates in the last four quarters, recent analyst revisions suggest bearish sentiment on near-term earnings prospects.

Everus Construction Group's Transmission & Distribution segment showed modest growth in Q2 2026 with revenues up 7.1% to $227.5 million and EBITDA margin improving to 14.4%. However, backlog growth remains limited at 1% sequentially and declined year-over-year, suggesting slower order momentum. The company faces competition from larger players like Quanta Services and MasTec, which are experiencing stronger utility infrastructure demand with significantly higher backlog growth.

MasTec (MTZ) has underperformed its industry peers over the past six months, declining 34.3%. While the company benefits from strong backlog and solid demand across infrastructure markets, near-term challenges including Communications segment weakness, negative free cash flow, project timing delays, and premium valuation warrant caution. The stock has been assigned a Zacks Rank #4 (Sell) rating.

MasTec (MTZ) delivered robust Q2 2026 results with 23.4% revenue growth and 48.8% EPS surge to $2.22, supported by a record $21.4 billion backlog up 30% year-over-year. The company raised full-year EPS guidance to $9.30 (42% growth) and completed the Superior Group acquisition, adding 3,000 employees and strengthening data-center capabilities.

MasTec (MTZ) reported record second-quarter revenues of $4.4 billion with a 18-month backlog of $21.4 billion, driven by strong demand in clean energy, power delivery, and pipeline infrastructure.

However, MTZ faces intense competition from Quanta Services and EMCOR Group, and the stock trades at a premium valuation with a Zacks Rank #4 (Sell) rating.

MYR Group's Transmission & Distribution segment reported 10% revenue growth to $1.06B in H1 2026 with operating income jumping 32.6%, driven by strong demand for grid upgrades, electrification, and data center infrastructure.

(EME) reported strong second quarter 2026 results for its U.S. Industrial Services segment, with revenues climbing 25.9% to $353.8 million and returning to profitability with $9.6 million in operating income.

Quanta Services (PWR) has delivered impressive 64.6% YTD returns driven by strong infrastructure demand, record $53.4B backlog, and strategic acquisitions. However, elevated valuation at 36.92X forward P/E—significantly above industry average of 23.67X—raises concerns about sustainability. The company maintains a Hold rating despite favorable long-term prospects, as much of expected growth appears already priced in.

Dycom Industries (DY) reported 50.6% revenue growth to $3.97B in H1 fiscal 2027 with record backlog of $12.24B, driven by AI-driven digital infrastructure investments in fiber and data centers. The company raised fiscal 2027 guidance and authorized a $150M buyback, but faces headwinds from heavy telecommunications customer concentration (80% of revenues), margin pressures, tariff risks, and project timing uncertainties. Despite trading at a discount to peers with strong ROE of 25.3%, analysts maintain a cautious Hold rating citing execution risks.

Quanta Services stock rose 3% on Friday after Citigroup analysts identified it as one of four construction stocks that historically outperform the S&P 500 by ~2% in the 10 days following major storms. The analysts cited Hurricane Isaias as a potential catalyst.
