Q&A highlights
7
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.”
asked by Alex Rygiel · answered by Jose Mas
How does the current cycle compare to past ones, and is the mid-30s EPS growth sustainable into 2027, led by Pipeline or Clean Energy?
Jose Mas described the current momentum as "incredible" and the best he's seen in his tenure, with every business "humming" and opportunities across the board. He expects it to get better and will lay out longer-term targets at the Investor Day.
“I can't remember a time where every business was just humming right, where everything just -- everything just had great opportunities in front of it, where we see backlog growing across the board where we see momentum actually increasing. So I think from a total business perspective, it's just as good as I've ever seen.”
asked by Andrew Kaplowitz · answered by Jose Mas
To what extent will the data center piece of Clean Energy and Infrastructure be the main narrative, and how much will natural gas plants contribute?
Jose Mas clarified that CE&I has four buckets (renewables, industrial/conventional power, infrastructure, general buildings/data centers), all showing backlog growth. The data center opportunity is "massive" and will play a "big role," but conventional power generation (gas-fired) will also be a part of the growth story, though not the leading part.
“Obviously, the data center opportunity subset is massive, and it's 1 that I think will play a big role in MasTec's future... It won't be the leading part of our growth story, but it will definitely be a part of our growth story, and I think we're well exposed to all of it.”
asked by Steven Fisher · answered by Jose Mas
On CE&I, where is the strength coming from (clean energy, civil, street highway, GC awards), and did LNTP projects come down with the backlog build?
Jose Mas reiterated that backlog increased across all four CE&I buckets (renewables, industrial, infrastructure, general buildings), not just data centers. LNTP work is either at the same level or has increased, indicating strong potential for continued backlog growth in renewables and the segment overall.
“On our Clean Energy and Infrastructure business, right, in all 4 buckets backlog increased, I think, maybe in general buildings we were flat. So to the point of it being data center driven, it was not. It was really made up from the other 3 parts of the business.”
asked by Brian Brophy · answered by Jose Mas
How does MasTec differentiate between organic growth and M&A, and to what degree is the company prioritizing growth that generates the best margin/return?
Jose Mas stated that after integrating past acquisitions and strengthening the balance sheet, MasTec is now more active in M&A, which is strategic and focused on bolstering existing areas. He emphasized that the company is not chasing revenue but seeking opportunities that align with leadership strength and offer optimal margins, expanding within current businesses rather than jumping into new ones.
“I do think you're going to see us be a lot more active in M&A for sure than we've been in the last couple of years... I don't really see us jumping into a lot of new businesses, but quite frankly, I see us really trying to expand the ones that we're in and take advantage of the opportunities within those.”
asked by Jamie Cook · answered by Jose Mas
Given strong demand, how is MasTec's ability to resource upwards (labor, facilities) to meet demand, and is it getting harder?
Jose Mas highlighted that MasTec is a "people business" and its workforce is a critical, irreplaceable asset. He noted the company is constantly adding resources, with headcount up ~6,000 YoY and ~2,000 sequentially. He acknowledged that hiring can impact margins but sees the business as more consistent now, benefiting from growth and associated margin opportunities.
“When we look at just pure numbers, right, I think we're up about 6,000 people year-over-year. We're up just under 2,000 sequentially. So it's -- quite frankly, it's a machine, right? We're constantly adding people. We're constantly adding resources. We're constantly manning to the opportunities that are in front of us.”
asked by Sangita Jain · answered by Jose Mas
How does the tax equity pause by banks impact renewables visibility, especially for 2027 projects, and has MasTec assessed its portfolio exposure?
Jose Mas expressed confidence in MasTec's '27 book of business due to strong customer alignment. He also stated that issues like the tax equity pause will be fixed by the administration because renewables are critical for the country's growth, and the implications of not fixing it are too great.
“I have a high level of confidence that the things that need to be done to fix issues like this will happen irrespective of that, that was a general comment for the industry. I feel good about our portfolio.”

Detailed narrative
01
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.
02
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.
03
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.
04
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.
05
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.
06
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.
