MasTec Lifts 2026 EBITDA to $1.5B: Is Execution Catching Up to Demand?
Read MoreHide Full Article
Key Takeaways
MasTec's Q1 revenues jumped 34% to $3.83B, and adjusted EBITDA rose 73% to $284M.
MasTec now guides 2026 revenues of $17.5B, adjusted EBITDA of $1.5B and EPS of $8.79.
MTZ says AI-led data center, fiber and grid projects offer a multiyear tens-of-billions opportunity.
MasTec, Inc. (MTZ - Free Report) delivered one of the strongest quarters in its history, prompting management to raise its 2026 adjusted EBITDA guidance to $1.5 billion from prior expectations. The company’s first-quarter performance highlighted not only accelerating demand across key infrastructure markets, but also improving execution as large-scale investments begin translating into stronger profitability.
First-quarter 2026 revenues rose 34% year over year to $3.83 billion, while adjusted EBITDA climbed 73% to $284 million. Adjusted EPS surged 174% to $1.39, significantly ahead of guidance. Management emphasized that growth was broad-based, with strength across Power Delivery, Clean Energy & Infrastructure, Communications, and Pipeline operations. Backlog also reached a record $20.3 billion, supported by a consolidated 1.4x book-to-bill ratio.
A major driver behind the improved outlook is MasTec’s growing exposure to AI-related infrastructure spending. The company continues to benefit from rising investment in data centers, fiber connectivity, grid modernization and power generation. Management noted that AI-driven demand for data center interconnectivity and electricity infrastructure is creating multiyear opportunities worth “tens of billions of dollars.” These trends are fueling stronger demand across both telecom and power delivery operations.
Importantly, profitability improvements are no longer limited to just one segment. Power Delivery EBITDA increased 40% year over year, supported by expanding margins and strong transmission demand. Pipeline EBITDA more than tripled as utilization and execution improved, while Clean Energy & Infrastructure generated 56% EBITDA growth amid robust renewable and data center-related activity. Even Communications, despite one-time charges tied to exiting select DIRECTV markets, continued to post solid organic growth and improved visibility.
Looking ahead, MasTec now expects 2026 revenues of $17.5 billion, adjusted EBITDA of $1.5 billion and EPS of $8.79, representing year-over-year growth of 22%, 30% and 34%, respectively. With AI infrastructure, power transmission, pipeline expansion and data center construction all accelerating simultaneously, management believes the company is entering one of the strongest growth cycles in its history.
MasTec Competes in a Fast-Scaling Infrastructure Market
Within energy and infrastructure construction markets, MasTec operates alongside well-established peers such as Sterling Infrastructure, Inc. (STRL - Free Report) and Quanta Services, Inc. (PWR - Free Report) , both of which are similarly navigating the challenge of scaling growth while maintaining margin discipline.
Sterling has recently been seeing its strongest momentum in mission-critical site development. In the first quarter of 2026, revenues surged 92% year over year, while adjusted EBITDA more than doubled and margins expanded to a first-quarter record of 20%. That performance was led primarily by the E-Infrastructure segment, where revenues increased 174%, supported by robust data center activity, large semiconductor-related awards and expanding multi-year customer programs. Sterling’s combined backlog climbed to $5.2 billion, with management highlighting more than $5 billion of visibility within E-Infrastructure alone.
Quanta, by contrast, remains most deeply positioned in electric power infrastructure, where its scale, transmission and distribution expertise and long-standing utility relationships continue to provide a competitive advantage. Management highlighted particularly strong demand tied to grid expansion, generation buildout and the rapid growth of technology and load-center infrastructure. Scale benefits showed up clearly in consolidated profitability. In the first quarter of 2026, Quanta’s gross profit increased to $1.11 billion from $834 million in the year-ago quarter. Gross margin expanded to 14.1% from 13.4%, reflecting improved profitability on higher revenue volume.
