Coral Gables, FL, October 29, 2026 — MasTec, Inc. (NYSE: MTZ) today announced third quarter 2026 financial results and updated full year 2026 financial guidance.

MasTec reported third quarter revenue of $5.2 billion and Adjusted EBITDA of $486 million, both up ~30% year-over-year. Backlog of $24.5 billion was ~46% higher year-over-year.

Jose Mas, MasTec’s Chief Executive Officer, stated, “We are pleased with our third-quarter performance, as both revenue and Adjusted EBITDA were ahead of our expectations, driven by strong Power Delivery results. Strength in Power Delivery was driven by both legacy operations and Superior, with both groups exceeding revenue and EBITDA guidance for the quarter.”

“As we noted throughout the third quarter, permitting related access delays on certain Pipeline projects impacted margins, as crews and equipment were underutilized. Construction has now commenced, and we are ramping production. Given the substantial number of pipelines expected to enter service over the next few years, we believe retaining our experienced crews is critical to capitalize on the significant level of industry investment ahead. We’re seeing this demand set play out, with Pipeline Infrastructure backlog growing ~26% sequentially in the quarter.”

Mr. Mas continued, “In Communications, as discussed in our second quarter earnings call, we saw certain customers defer spending in the second half of 2026, impacting our full-year revenue expectations. We are taking actions to improve this segment's margin profile and operating leverage through market cycles by streamlining our operations, procurement strategies, and support models to reduce indirect costs, including exiting underperforming markets. We expect these initiatives to begin contributing to improved profitability in 2027. We see a fundamental multi-year need for sustained investment in telecommunications infrastructure upgrades and maintenance to enable a significant increase in AI driven data consumption over the next several years.”

“With sequential backlog growth of $3 billion and another record consolidated backlog in the quarter, we have strong visibility for continued revenue and earnings growth across our diversified end-markets – with increasing geographic reach. We continue to see sustained demand strength across our service offerings, most notably in support of utility and large-load infrastructure, where our converging operations allow us to provide more integrated solutions to our partners.”

Paul DiMarco, MasTec’s Executive Vice President and Chief Financial Officer, noted, “We are updating our full-year guidance, introducing a range that results in Adjusted EBITDA change of ~1% at the midpoint versus our previous guidance. The range reflects the potential impact of delayed Pipeline project starts on labor and equipment utilization. With less time to hit run-rate production in 2026, near term margin recognition could be impacted. Revenue and earnings not recognized this year as a result of project timing are expected to shift into 2027.”

“We expect to generate over $1 billion in operating cash flow for 2026. Our strong financial position provides us significant flexibility to pursue accretive investments to support organic growth, execute our acquisition strategy and return capital to shareholders.”
