Mitigation:Management is confident in its 2027 portfolio and believes the administration will address such issues due to the critical importance of renewables for national growth.

Q&A highlights

With backlog up 28% YoY, how are pricing and contract terms changing, and will they become more important than volume?

Jose Mas stated that improvements in pricing and repricing from 2025 backlog growth are just beginning to impact financials and will play through 2026 and into 2027. The company feels good about its backlog and intends to improve segment-by-segment margins.

“I would argue that a lot of the improvements that we've seen in the business from a pricing perspective, obviously, from a growth perspective, haven't really even started hitting our financials yet, right? I think we're just at the beginning of seeing some of the improvements that we saw in '25 relative to backlog and repricing, and I think that will play through the balance of '26 and into '27.”

Detailed narrative

Record Q1 Performance and Raised Outlook

MasTec achieved its strongest first quarter in history, with revenue of $3.829 billion, adjusted EBITDA of $284 million, and adjusted EPS of $1.39, all exceeding guidance and showing significant year-over-year growth of 34%, 73%, and 174% respectively. This strong performance led to a raised full-year 2026 guidance for revenue to $17.5 billion, adjusted EBITDA to $1.5 billion, and adjusted EPS to $8.79, reflecting confidence in continued momentum and an improving outlook.

Strategic Positioning in Critical Infrastructure

The company is strategically positioned at the center of significant, durable investment trends in critical infrastructure, including AI-driven data centers, grid reliability, energy demands, and connectivity. Management highlighted the multi-year opportunity in data center interconnectivity, estimated in the tens of billions of dollars, driven by demand for fiber capacity and redundancy.

Power delivery also presents long-duration, highly visible opportunities due to load growth, resilience, and energy transition, with AI and data centers potentially driving up to 12% of total U.S. electricity consumption by the end of the decade.

Pipeline Segment's Strong Visibility and Growth Potential

The Pipeline segment delivered a terrific Q1 with revenue of $682 million, almost doubling year-over-year, and EBITDA margins of 21%. Despite current backlog not fully representing potential, management expressed strong visibility for 2027 and beyond, expecting revenue to exceed $3 billion and potentially reach historical highs of $3.5 billion as early as 2027.

This growth is driven by the growing need for natural gas infrastructure to support gas-fired generation and global LNG demand.

Clean Energy & Infrastructure Driven by Data Centers and Renewables

The Clean Energy and Infrastructure (CE&I) segment saw robust growth, with revenue up 45% year-over-year to $1.3 billion and organic growth over 30%. Renewables revenue increased 63% year-over-year, and general building revenue surged 166%. The segment's backlog reached a new record of $7.3 billion, with a total book-to-bill of 1.6x.

Data center development is identified as a massive, multi-year opportunity leveraging MasTec's construction management and self-perform capabilities across civil, power, telecom, and maintenance.

Focus on Organic Growth and Strategic M&A

Following a period of integrating prior acquisitions and strengthening the balance sheet, MasTec is now poised for more active M&A, particularly in areas that bolster existing segments or geographic presence. Management emphasized that M&A will be strategic, not growth for growth's sake, and will complement the strong organic growth opportunities across all segments.

The company feels well-equipped with leadership strength to handle multiple areas of growth and execute on opportunities.

Workforce Expansion and Operational Efficiency

MasTec continues to expand its workforce, adding approximately 6,000 people year-over-year and nearly 2,000 sequentially, underscoring its commitment to meeting growing demand. Management views its workforce as a critical, irreplaceable asset and a 'machine' constantly adding resources. The company is also focused on improving operational efficiency, evidenced by efforts to reduce seasonality and improve project execution, which contributed to Q1's strong performance and is expected to drive margin expansion.
