Thank you for standing by, and welcome to MasTec's Second Quarter 2025 Financial Results Conference Call. Today's call is being recorded. I'd like to turn the call over to Chris Mecray, Vice President of Investor Relations.

Chris Mecray

Management

Good morning, everybody, and thank you for joining us for MasTec's Second Quarter 2025 Financial Results Conference Call. Joining me today are Jose Mas, Chief Executive Officer; and Paul Dimarco, Chief Financial Officer. We've prepared slides to supplement our remarks, which are posted on MasTec's website under the Investors tab and through the webcast link. There's also a companion document with information and analytics on the quarter and a guidance summary to assist in financial modeling. Please read the forward-looking statement disclaimer contained in the slides accompanying this call. During this call, we will make forward-looking statements regarding our plans and expectations about the future as of the date of this call. Because these statements are based on current assumptions and factors that involve risks and uncertainties, our actual performance and results may differ materially from our forward-looking statements. Our Form 10-K, as updated by our current and periodic reports, includes a detailed discussion of risks and uncertainties that may cause such differences. In today's remarks, we'll be discussing adjusted financial metrics reconciled in yesterday's press release and supporting schedules. We may also use certain non-GAAP financial measures in this conference call. A reconciliation of any non-GAAP financial measures not reconciled in these comments to the most comparable GAAP financial measures can be found in our earnings press release, slides or companion documents. I'll now turn the call over to Jose.

Jose Ramon Mas

Management

Thank you. Good morning, and welcome to MasTec's 2025 Second Quarter Call. Today, I will be reviewing our second quarter results as well as providing my outlook for the markets we serve. I am pleased to report that we exceeded guidance in revenue, met our EBITDA expectation and beat our EPS guidance for the second quarter. We're happy to have delivered significant year-over-year growth in revenue despite the difficult comparison from the Mountain Valley pipeline completion in the first half of last year. The remaining segments, our non-pipeline business improved EBITDA from $181 million to $257 million in this year's second quarter, a 42% year-over-year increase. Revenue for our non-pipeline business was up 26% with Power Delivery and Clean Energy and Infrastructure, both up 20% and Communications up 40% year-over-year. We expect revenues to sequentially increase again by double digits in the third quarter. Margins for our non-Pipeline segments also improved 100 basis points year-over-year and posted a strong 230 basis point sequential improvement. Both our Communications segment and Power Delivery segment improved EBITDA margins 300 basis points sequentially and Clean Energy improved 120 basis points. We expect further sequential improvements in the third quarter in both our Communications and Power Delivery segments with margins in our Clean Energy segment expected to be about even with the second quarter. Total company backlog in the quarter also remained healthy, posting a 23% year-over-year growth, including a 4% sequential increase, resulting in a book-to-bill ratio in the second quarter of 1.2x. The sequential growth from first quarter included an 11% increase from Clean Energy and Infrastructure, inclusive of solid growth for both renewables and infrastructure and by ongoing growth of 2% from Communications, offset partly by flatter performance in pipeline and power delivery, inclusive of stronger burn rates in the period. We…

Paul Dimarco

Management

Thank you, Jose, and good morning. As Jose mentioned, we are very pleased that our second quarter results exceeded guidance, coming in large part from strong sequential volume development and continued solid execution. We remain highly confident in our business positioning today and into the years ahead, and this is true across all of our end markets given solid demand drivers that will require a significant investment in infrastructure for years to come. This is the case regardless of which technologies are favored and whether financing mechanisms include government incentives. Our customers are clear. They need us to fulfill plans that include major projects across the spectrum of markets we serve. Let me start with some quarterly highlights. Second quarter revenue was well above expectations at $3.54 billion, a new quarterly record, with 20% growth year-over-year and 25% growth sequentially from the first quarter. Adjusted EBITDA of $275 million met our forecast. Three of our 4 segments beat volume expectations in the period, while the standout performance in profit and margins came from Clean Energy and Infrastructure. 18-month backlog at quarter end totaled $16.45 billion, an increase of 4% from the first quarter and 23% year-over-year. This represents another record level of total backlog for MasTec with the growth led by an 11% increase recorded at CE&I that included continued strong bookings in the renewables portfolio, which is fully booked for the current year and continues to build momentum for 2026 and beyond. We generated cash flow from operations of $6 million in the second quarter and $84 million year-to-date, with DSOs at 65 days, a 1-day improvement from the first quarter, both in line with our expectations. Our strong second quarter revenue growth with consistent DSOs drove higher working capital investment in the quarter. Free cash flow for Q2…

[Operator Instructions] We will now take our first question from Steven Fisher from UBS.

Steven Michael Fisher

Analyst

Just to follow up on the clean energy comments you made. Just curious about kind of what you experienced in terms of customer feedback and activity during the quarter as all the policy uncertainty played out, I know you -- it sounds like you're pretty well set on '25, but did that kind of change things around with any specific projects or what you might have already had booked for 2026? And how much actually do you have in your '26 plan booked at the moment?

Jose Ramon Mas

Management

Steve. So I would say a couple of things. I'd say our customers so far have been unaffected, right? I think what everybody's plans were for '25 are ongoing, quite frankly, what everybody's plans were for '26 are ongoing. The work that we've booked, the success that we've had in bookings in both the first and the second quarter have nothing to do with the federal legislative process as it's played out. I think it's completely solidified our plan for '25. It's put us in an incredible position for '26 where we would expect to further grow that piece of the business. And at the end of the day, we're really excited about what came out of the legislation. We think the one big beautiful bill is a good bill for MasTec. Obviously, we've got an executive order that we're paying attention to. But we work for top-tier developers, and we think that they're in the best position to really maintain their business over a really long cycle.

Steven Michael Fisher

Analyst

Okay. That's helpful. And then in power delivery, just curious how you're thinking about the timing of bookings here. I think, Jose, you said the coming periods. Could that mean still the second half of this year? And what you think are your focus projects here? Is it more on the very high-voltage lines? Or it would be substations or anything else or all the above?

Jose Ramon Mas

Management

Well I mean we're focused on all of the above. I think we've made great progress in the business. If you look at our guidance, we're guiding to grow just under 20% for the year. That's virtually all organic. So I think we've done a great job in that business of building off of what already was a good 2024. I think margin progression is happening in that business as we expected. We're really excited about what the second half is going to bring for us in power delivery. We think our positioning in the market is fantastic. We expect to be a player on big projects as we go forward, but also on the day-to-day business, right? The day-to-day business is really important for us. It's the bulk of what we do. We're constantly winning projects. We're constantly getting more competitive. We're talking a lot about margin expansion opportunities and what we've done to build margins. And if you think about where we've come in that business from just a few years ago in '22, '23 as we were very acquisitive in that business, I think we've made tremendous inroads in margin expansion and then really positioning in the market, and we're really excited about what's going to come in that market for us.

We will take our next question from Philip Shen from ROTH Capital Partners.

Philip Shen

Analyst

First one as a follow-up, Jose, on the [indiscernible] your expectations for how that could play out and maybe the different outcomes? And how are the Tier 1 customers positioned for those different outcomes?

Jose Ramon Mas

Management

Sure. So look, I think a number of our customers today have a lot of -- a very large portfolio of safe harbor projects. The way that the legislation is written is through '27, everybody keeps their credits. Beyond '27 it's what you have safe harbor. There's a lot of opportunities for people to further safe harbor projects all the way into the middle of '26. There will be some changes in the executive order relative to that. We think they'll be manageable. And more importantly, we think they'll be manageable by the top-tier developers. I think the work that we've done post the IA acquisition in terms of really focusing ourselves on the customers that we were working for, the relationships that we're creating. When you look at our customer base today in that industry, we think it's best-in-class. It's Tier 1, and we think those are the ones that are best positioned to take advantage of the opportunities that will exist to safe harbor. It literally puts your projects in play all the way to 2030. Obviously, there's another election in 2028. So we'll see what happens. But we're excited about, again, not just '26, where I have no doubt in my mind that this business is going to grow for us in 2026. I think it will grow beyond that. And over time, and we said it in our prepared remarks, I actually think the market is becoming a lot more competitive. When you look at the sources of power that exist, right, you've got nuclear, which is a ways out. You've got gas that we'll see significant increases in 3 to 5 years. But when you look at the price of that, renewables start getting really competitive even without subsidies. When you look at the rest of the world and what they're able to build renewables at in a free market, it's a low cost. So it is a formidable form of power generation at a low cost, especially when you consider storage. And we think the market is going to be strong for a really, really long time with or without federal incentives.

Philip Shen

Analyst

Great. And then you talked about also how bookings have accelerated, I think, for clean energy. And I think in the back half, that might continue. And so I was wondering if you could just kind of give a little bit more color post-OBB, what the conversations were like with customers? Did you see really an aggressive kind of amount of activity in July? And then do you expect that acceleration to sustain through Q3 and Q4? Or do you think that kind of slows down as we get through the year?

Jose Ramon Mas

Management

I would say not yet. So the bookings that we enjoyed in Q1 and Q2 had nothing to do with the bill, right? So in Q1, we booked over $1 billion in new projects, which we were really excited about. I think we had a -- I don't remember, 1.4x book-to-bill in that market in Q1. We booked $1.6 billion in Q2. And I think that acceleration is critically important. I think we're going to have a really strong second half of the year. I think we're going to have a really good third quarter yet again. And I would argue that none of that has to do with the bill. depending on what happens with the executive order, there is a possibility in place that people work really hard to safe harbor and pull in a lot of work. We have not taken any of that into account in any of our thought process. That would -- we don't know. Obviously, that would be upside to MasTec and others in the industry, but we'll keep working with our customers to see if that's going to be required or not. Hopefully, it won't be and people will work off their current safe harboring over the course of the next 5 or so years.

Philip Shen

Analyst

Great. One more, if I may, as it relates to margin. In terms of EBITDA margin, what are your latest thoughts on the overall trajectory in '26 and '27? Are double-digit margins still on the table in the near to medium term?

Jose Ramon Mas

Management

Yes. So the question is from a -- I'm not sure if the question is from a total company perspective or specific to clean energy.

Philip Shen

Analyst

Total company.

Jose Ramon Mas

Management

Yes. So from a total company perspective, look, we're really bullish on every segment that we operate in. We're seeing significant acceleration. As we said, obviously, the big driver to margins in our business is our Pipeline segment. It's historically been our highest margin business. We're really bullish about what's going to come there. I think when you look at our guidance for this year, we're in that low 8% range. I don't know that we're not going to sit here today and talk about getting to double digits in 2026. But over the long term, that is our goal. That we think we can achieve that. Obviously, it has a lot to do with the mix of our business. But we think today, when we look at our outlook over the next few years, the mix potential of our business has never been better.

Operator

We will now move to Andy Kaplowitz from Citigroup.

Andrew Alec Kaplowitz

Analyst

Jose, so you did raise your pipeline revenue forecast a bit, but as you said, backlog was down slightly sequentially. So could you give us a little more color on what you're seeing? You mentioned, I think, some projects you expect to book shortly. Is it possible to quantify that? And then I know you've talked about revenue at least as big as in '24 and '26. So maybe you could update us on the potential of this cycle. Could it be comparable to pre-COVID levels?

Jose Ramon Mas

Management

Sure. Thanks for the question, Andy. So a couple of things I'd say. Our pipeline business isn't about this year, and quite frankly, it isn't even about next year. We stand firm with what we said before, which is we think that our 2026 pipeline business will look a lot more like our '24 pipeline business. which is a sizable increase from where we'll be in 2025. Historically, obviously, it's been our best-performing business. It's been our highest margin business. It peaked at about $3.5 billion of revenues. I think on our last call, we said if the market plays out the way that we're seeing, there's potential to ultimately get there over time. We still feel that way. It's somewhat remarkable that we're even saying that based on where the business has been in the last couple of years. But the level of activity that we're seeing today is, in my mind, somewhat unprecedented. Again, not necessarily for '26, but even beyond '26. And we're making significant investments today, right? We're investing in people. We're investing in equipment, and we're preparing for what we think is going to be a really large cycle, which we'll see the beginning of in '26.

Andrew Alec Kaplowitz

Analyst

Helpful, Jose. And maybe a similar question in communications. There seems to be a ton of drivers there, whether it's fiber-to-the-home, but now fiber to the data center. I think the big beautiful bill helps with 100% bonus depreciation. So maybe you can talk about sort of the durability and duration of the cycle as you see it today, both in wireline and wireless.

Jose Ramon Mas

Management

So again, Andy, it's been something that somewhat caught us by surprise, the strength of the market. Our revenue guidance this year is north of 20%, again, all organic. When you look at the first 2 quarters, we outpaced that. We're bullish about not just this year, but what's going to, quite frankly, happen in '26 and beyond. We've got a number of new customers that keep coming to us with different plans with different opportunities. We're pricing a lot of things in that market, there's no reason that we don't think that next year is going to be another really strong growth year. And quite frankly, we think we're at the beginning of the cycle there as well. There's been a lot of talk about [indiscernible] and [indiscernible] hasn't even shown up yet. So we'll see how that also impacts the market. But today, the drivers of the business, that middle fiber expansion, which is being built to not only focus on data centers, but really all of the growth that we're seeing across different industries is really driving that business, and we don't expect it to end anytime soon.

Operator

We will take our next question from Sangita Jain from KeyBanc Capital Markets.

Sangita Jain

Analyst

Jose, if I can follow up with one more on the Communications segment. Can you talk specifically about MasTec split wireline versus wireless as you lap the Ericsson order and as we talked about all the fiber opportunities come up?

Jose Ramon Mas

Management

Sure. So again, historically, the wireless business for a long time was the biggest piece of the business. It's not anymore. Our wireless business is probably roughly 40% of what we do. The balance is wireline. Wireline has a lot of growth. Our wireless business, though, we're still really bullish on. The Ericsson project is really less than a year old. It really started in the second half of last year. So we're in the first year of what's going to be a long multiyear cycle on that specific opportunity. We see tons of opportunities with other carriers on the wireless side based on what they've got planned in the coming years. We actually think that, that business will see, again, significant growth opportunities within the entire communications sector. And the wireline market is really -- there's as much demand as we've seen. So that's going to continue to grow for us. So we think both sectors are strong. Both sectors have tremendous growth opportunities over the coming years. And while the wireline is just bigger in total scope, we really like our position in both.

Sangita Jain

Analyst

And if I can follow up on that itself. Would you need to make investments on that wireline side similar to what you are doing in pipelines if the cycle does materialize the way it's looking today?

Jose Ramon Mas

Management

I think we've done it. We talked a little bit about that on our first quarter call. We also added people in that business in a sizable way in the second quarter. I think we've talked about ramping up for the demand. I think we've been in that circumstance now for multiple quarters. So I actually think we're pretty well positioned there. I don't think that the level of investment on a go-forward basis is going to be different than what it's been in the last couple of quarters. So I think we'll continue to build off that.

Operator

Operator

We will take our next question from Julien Dumoulin-Smith from Jefferies.

Julien Patrick Dumoulin-Smith

Analyst

Just maybe to kick it off a little bit, let's talk about margins here a little bit. I mean, obviously, you're talking about investing and reinvesting in the business in anticipation. What's the time line and cadence here of seeing that inflect in certain segments here? I mean, obviously, as you said yourself, some of those may not necessarily fully translate in bookings or at least meaningful revenue increases in '26. How do you think about the cadence of that margin improvement through the cycle here? And then secondly, to follow up on the pipeline commentary earlier, there's some pretty mega projects contemplated here for the back half of the year. I mean, obviously, given your market position, can we make presumptions about some of those large ones and your position there in? I mean, just being aligned with those partners?

Jose Ramon Mas

Management

Yes. So I'd say a couple of things. I'd say when we think about investments relative to margin, our backlog is way up, I mean, considerably up since the beginning of the year. It's been across virtually all of our segments. We see what's coming. We see what's not in backlog, but we feel confident we're going to win. And that's the reason for the investment decisions that we've made. So we're really trying to get ahead of that. We're really trying to be in a position so that when that work comes in, we can hit it and execute on the highest margin that we can relative to that. So we think that a lot of our investment will be captured in '25 relative to what we're going to need to take advantage of some of these growing markets. Obviously, there's always a need for investment, but we think we're doing a lot of that as we speak. As it relates to pipeline, look, we're the largest pipeline builder in North America. We think we're the best pipeline builder in North America, bar none. We've got the largest fleet. We've got great people, and we think that for any owner that's out there that's interested in building a pipeline, there would be no reason not to contact MasTec and want MasTec on your project for lots of reasons. And we think that, that will play out in the marketplace.

Julien Patrick Dumoulin-Smith

Analyst

Got it. And just to clarify from earlier, the renewable timing, obviously, you saw good progress here. How do you think about the timing of those projects getting pulled in? You made allusion to it earlier, but maybe to put a finer point on it, do you think that you actually see a shift forward into '26 and '27 specifically on the renewable business even within your existing backlog?

Jose Ramon Mas

Management

It depends on -- well, not in the existing backlog because our existing backlog is only 18 months. So we wouldn't have anything today in backlog for 2027, regardless of where we stand with customers and our expectations for the work that we'll do for them in '27. I'd say that I don't think customers are there yet. I think in a perfect world, customers have dozens of gigawatts of projects planned from now through 2030. And hopefully, they can work that plan off in the process that they're expecting. If something changes relative to the executive order and they have to accelerate that, we will definitely see a significant acceleration of the business, and then we'll have to manage to that. I think that's speculative, so I don't really want to get into that. I actually think that there's going to be a reasonable way to safe harbor projects, and we won't see significant acceleration across the industry, but the time will tell.

Operator

We'll take our next question from Atidrip Modak from Goldman Sachs.

Atidrip Modak

Analyst

Jose, you mentioned a headcount increase on the pipeline side in particular. Can you talk about the capacity building targets there? And how many large pipelines can you be working on at the same time? And is there a difference in utilization rates as we think of margins between the long-haul lines and the connector lines?

Jose Ramon Mas

Management

Sure. So the 4,000 number that we gave was company-wide. Obviously, pipeline was a big part of that. We feel like we perform well on all types of projects, large and small. We've said that in the past. We think the margin opportunity and potential doesn't necessarily vary by type, by size of projects. Sometimes it does by contract structure. So the cost-plus world allows you a lower margin than if you're doing units. So we've predominantly done mostly units with some cost plus. We'll see what that mix looks like in the future. In terms of scale, we would argue we're underutilized, right, at $2 billion. Our peak was, I don't know, a couple of years ago, we were doing $3.5 billion in sales in pipeline. So we think that the opportunity for us to increase the level of productivity with the assets that we own is tremendous. And we don't think that there is a -- we don't think from a terms of scale and our ability to perform that there'll be a lack of projects. So for us, it's going to be about who do we want to partner with, what customers do we want to work for and how big and how quick do we want to scale that business over time.

Atidrip Modak

Analyst

Got it. And then on that note, I guess, on the verbally awarded contract that you were talking about, can you help us understand the nature of that between sort of connector lines or long-haul lines? And is there a way to assess how much of the pipeline on average you are bidding for or you could be getting awards for?

Jose Ramon Mas

Management

In terms of the total market or a specific project?

Atidrip Modak

Analyst

For a long-haul pipeline, I mean, are you bidding for the entire thing? Is it reasonable to expect you're going to get the entire thing or 40%, 50%, anything like that?

Jose Ramon Mas

Management

Yes. Look, so it depends on the customer. There are projects that we've done in their entirety. There are projects where we've done half a project, the majority of a project, and it all depends on the customer, the size of project, the location, the risk tolerance, right? For us, again, we've got a lot of availability. We've got, we think, the most flex in the marketplace relative to our ability to gear up for any project. And we are going to responsibly try to be as strong as we can in that business and grow that business as quickly and as reasonably as we can at the margin profile that we've historically enjoyed.

Operator

We will take our next question from Drew Chamberlain from JPMorgan.

Drew Walker Chamberlain

Analyst

First one, I just want to follow up on the pipeline margins here. And obviously, I appreciate the investment that you've put into the business this quarter. But can you maybe talk a little bit about how much further investment you need to have in 2025 to be ready for the coming years? And then also, I mean, maybe just touching a little bit -- I know we've talked about the revenue volumes in the past being 3.5%. But I mean, also the margin profile then was also in the 20s, right? And so I'm just wondering if you think about as that revenue ramps, do you think there's any structural change in what the margin potential is here? I'm not talking about like what you've guided to, but how you think about the potential for that business? Are there things that have changed, labor costs, other input costs that might have necessarily changed to make you think differently about the margin profile?

Jose Ramon Mas

Management

In the long-term answer is no. There's nothing structurally different. If you look at -- even if you look at '25, which I know we don't want to focus on '25, but if we look at the back half of '25, our guidance profile on the margin side is way up, right? So we'll be back to the mid-teens in the second half of '25 versus the first half of '25. Again, '26 isn't the peak year by any stretch of the imagination. I think the cycle starts in '26. I think the performance in '26 will obviously be better than the performance in '25. Again, we've said approaching '24 levels. But over time, as the volume continues to increase, there is no reason why we shouldn't be able to attain historical margin profiles. Again, we've always guided towards high to mid-teens in that market. The opportunity to outperform that is there, but that's based on execution. So no, we don't think there's anything structurally different that wouldn't allow us, if we execute well to achieve a similar level of margins as we've historically done.

Drew Walker Chamberlain

Analyst

Okay. And then a quick one on cash. I mean, obviously, a big ramp here in the second half of the year in the implied guidance. And can you just maybe talk about what's giving you confidence in that ramp? I mean I appreciate you did it last year, and so it's clearly achievable. But what's giving you confidence this year? And then maybe if there are a few points that make you worried about whether it's achievable or not things that could be headwinds in the second half to cash, I mean, what would those be?

Paul Dimarco

Management

It's really just timing of the sequential growth, right? So we had big sequential growth in Q2, and it will moderate as we go through Q3 and Q4 from the prior quarter. It's just working capital. That's the only working capital timing. Our DSOs in the low to mid-60s are where we think they'll be structurally. So it will have a benefit of reducing those any further. So it's just timing of investing for the various jobs.

We will now move to Jamie Cook from Truist Securities.

Jamie Lyn Cook

Analyst

Nice quarter. I guess, Jose, obviously, lots of growth opportunities ahead of you and you're investing in your business as you talked about increasing your labor. I'm wondering to what degree does that create a short-term headwind as you think about margins, at least in the first part of 2026, I mean just as we're absorbing those costs and training people, et cetera? And then I guess my second question, and I'm sorry if someone's asked this, but there's like 5 calls this morning. Just your thoughts on M&A, your peer is making some pretty aggressive moves on the acquisition front. To what degree do you think you need to do more acquisitions to continue to enhance your competitive positioning? And to what degree do you need to do acquisitions to ramp the labor growth?

Jose Ramon Mas

Management

Yes. So a couple of things. I'd say that when we look at the investments that we're making, we think we're absorbing those costs in 2025. We think we absorbed some of them in the second quarter, which was why we candidly beat revenues, but didn't necessarily have a lot of flow-through on EBITDA. We've got a little bit of that in Q3, again, where we've guided revenue slightly higher, but without a significant amount of flow-through, we think that has to do with the investments. We actually think that starts to turn as early as the fourth quarter. We don't expect there to be significant lingering impacts of that going into '26, where we think will be highly utilized across these investments that we've made. So we're -- again, we think that's a great story and really important. As it relates to M&A and what we've said in the past, Look, we were very acquisitive in the '22, '23 time frame. We talked about really focusing on the organic opportunities that are in front of us. That's been our focus. When you look at our revenue growth this year, when you look at our earnings growth, when you look at our 60% EPS growth this year relative to last year, that's been virtually all organic. And I think that, that was important for the organization at that moment in time with some of the issues that we had with the integration of IEA. We think we're through that. We think we're in a very different position. To your question of do we need to do M&A, our answer is we do not need to do M&A. When we look at '26, right, we see -- we laid out a goal when we did the IEA acquisition in the summer…

We will take our next question from Justin Hauke from Robert W. Baird.

Justin P. Hauke

Analyst

Great. I think most of my questions have been answered. I just have one quick one. Just turning back to the Communications segment. I think your previous guidance for the second half was that it would be kind of flattish. And now 3Q in particular, really strong. And I guess, second half up high single digits, maybe close to 10%. Is that the data center fiber work that's driving that? Or what's the change versus kind of the previous outlook that it would be flattish here in the second half?

Jose Ramon Mas

Management

Well, I think it's the outperformance in the first half, right? So if you look at the first half, again, we grew first half revenue versus last year in the comps business is up 38%, which is really impressive. I think that, if anything, I'd argue we're being a little conservative in the second half, and I think it's broad-based. I think the wireless business is performing well. It's strong. We've done a really good job of gearing up and we did a really good job of gearing up and preparing for some of the larger projects we had in that business. I think that's showing in execution today. We continue to see tons of wireline opportunities, new ones that we're pricing that will have some impact towards the end of '25, but quite frankly, will probably impact '26 more. So we continue to see activity. I think, obviously, the wireless build-out started in the second half of '25. So the '25 second half comps are more difficult than the first half '25. That's part of the reason for the large variances in growth. But again, when we look at the cycle and what we think we can accomplish in this business over a longer period of time, we think high single to low double-digit top line growth is very reasonable in this market for that segment.

We will now take our next question from Brian Brophy from Stifel.

Brian Daniel Brophy

I wanted to ask about power delivery margins. There was some discussion about project inefficiencies in the Q and I think the press release as well. And I think this is the second quarter you guys have talked about this. Any more color on what is driving these project inefficiencies? Is it related to GreenLink at all? And how should we be thinking about this potential headwind in the second half?

Jose Ramon Mas

Management

Well, if you think about our second half guide for margins in power delivery are double digits. We think we'll achieve that in both quarters, third and fourth. So I think it's no different than the commentary we put out in the past. I don't think there's anything significant to really highlight. I'd say in some areas, I think we had some weather impacts. We had -- geographically, we had areas that really improved in areas that probably held us back a little bit. I do think there -- we said it in Q1, there's some margin that we felt we left on the table there in the first half of the year. With that said, I mean, we were still up, right, in both earnings and in revenue on a year-over-year basis. So our revenue was up about 17% in the first half year-over-year. EBITDA was up 10% in the first half year-over-year. So it's not that we didn't improve. It's -- quite frankly, we thought we could have improved more, and I think we'll start to show that in the second half of the year.

We will take our next question from Brent Thielman from D.A. Davidson.

Brent Edward Thielman

Analyst

Congrats on all the momentum here. Jose, just at look, you got a lot of businesses that sort of benefit indirectly from the AI data center build-out. Maybe just refresh us on some of the things you're doing more directly for data centers, kind of size it for us? And are you investing more in it and trying to scale that up?

Jose Ramon Mas

Management

The short answer is yes. I think everything from -- we started in that world, we talked about it, it feels like a long time ago, but we really started that on the civil side of our business with our infrastructure business. I think it's grown where we're doing a lot of power associated work relative to data centers. We're obviously doing a lot of telecom work related to data centers. Our business continues to grow there. It's performing as expected or better. I think we're probably more optimistic about the longer-term opportunities of what we have in that market than we've ever been. And I think over the next couple of quarters, hopefully, we'll be able to talk more about what that is and what services we're specifically trying to target.

We will take our next question from Liam Burke from B. Riley Securities.

Liam Dalton Burke

Analyst

Jose, pipeline is accelerating and you laid out all the reasons why. Is it just the challenge you have in front of you scaling the business? Or has there been any change in the competitive front?

Jose Ramon Mas

Management

I mean we're not afraid of the competition. I think that it's a matter of -- there's obviously been a huge sentiment change. So if you would have asked our customers a year ago, the outlook was nowhere near what it is today. So I think as the -- obviously, the election changed a lot, the reliance on natural gas in the future has changed a lot. It's changed the business. Our customers are responding to that change, but it doesn't happen overnight, right? So any of these projects, there's obviously a lot of engineering planning, you got to order pipe. You got to work on routes and get permitting and -- and that's happening, right? So we're -- the level of activity that we're seeing is incredible. We will get more than our share of that, we believe, and it's just a matter of timing, right? So we're -- we see what's coming in the second half of the year. We're excited about it, and we're preparing for that. And that's kind of what's driving the business today and the investment decisions that we're making today.

Liam Dalton Burke

Analyst

Great. And then just real quickly, and you mentioned this in your prepared comments that nuclear is way out there. But are there any early discussions on any of the providers on getting you involved?

Jose Ramon Mas

Management

Look, it's the beauty of our business, right? We evolve with every one of our markets. We evolve in the different technologies as they come up. Obviously, we're paying really close attention to it. And there's no doubt in my mind that when the time comes that, that becomes a growing source of generation, we will be engaged.
