Good morning, ladies and gentlemen, and welcome to Sterling Infrastructure Fourth Quarter and Full Year Webcast and Conference Call. At this time, all lines are in listen-only mode, and following the presentation, we will conduct a question-and-answer session.
If at any time during this call you require immediate assistance, please press *0 for the operator. As a reminder, this call is being recorded on Thursday, February 26, 2026.
I would now like to turn the call over to Noelle Dilts, Vice President, Investor Relations and Corporate Strategy. Please go ahead.
Noelle Dilts
Good morning to everyone joining us, and welcome to Sterling Infrastructure's fourth-quarter and full-year 2025 earnings conference call and webcast. I'm pleased to be here today to discuss our results with Joe Cutillo, Sterling's Chief Executive Officer, and Nick Grindstaff, Sterling's Chief Financial Officer.
Joe will open the call with an overview of the company and its performance in the quarter. Nick will then discuss our financial results and 2026 guidance, after which Joe will provide some additional commentary on our markets and outlook.
We will then open the call up for questions. As a reminder, there are accompanying slides on the Investor Relations section of our website.
These slides include details on our full-year 2026 financial guidance. Before turning the call over to Joe, I'll read the Safe Harbor statement.
The discussion today may include forward-looking statements. Actual results could differ materially from the statements made today.
Please refer to Sterling's most recent 10-K and 10-Q filings for a more complete description of risk factors that could affect these projections and assumptions. The company assumes no obligations to update forward-looking statements as a result of new information, future events, or otherwise.
Please also note that management may reference EBITDA, adjusted EBITDA, adjusted net income, or adjusted earnings per share on this call, which are all financial measures not recognized under U.S. GAAP.
As required by SEC rules and regulations, these non-GAAP financial measures are reconciled to their most comparable GAAP financial measures in our earnings release issued yesterday afternoon. Our discussion of all results today, including revenue and backlog, refer to figures that adjust prior-period results to conform to the current accounting of our RHB JV, unless otherwise noted.
I'll now turn the call over to our CEO, Joe Cutillo.
Joseph Cutillo
Thanks, Noelle. Good morning, everyone, and thank you for joining Sterling's fourth-quarter and full-year 2025 earnings call.
I'd like to start by thanking our team for delivering another outstanding year in 2025. We achieved strong revenue growth of over 32% and adjusted diluted EPS growth of over 53%.
This is the fifth consecutive year we have achieved adjusted EPS growth of over 35%. Full-year gross margins reached 23%, and adjusted EBITDA margins exceeded 20% for the first time in our history.
The strength of our margins reflect our continued focus on pursuing opportunities that offer the most attractive returns. Additionally, our operating cash generation remains strong at $440 million.
We are pleased to discuss these results with you today, but even more excited about the opportunities ahead of us. The Sterling Way, which is our commitment to take care of our people, our environment, our investors, and our communities, while we work to build America's infrastructure, remains our guiding principle as we execute our strategy and grow the company.
Moving to the fourth-quarter results, revenue grew 69%, fueled by 123% growth in E-Infrastructure Solutions, and 24% growth in our Transportation Solutions. Organic growth in the quarter was 36%.
We grew adjusted earnings per share by 78% to $3.08, and adjusted EBITDA by 70% to $142 million. Additionally, operating cash flow generation in the quarter was again very strong at $186 million.
Our backlog position and strong visibility drive our confidence in the future. Signed backlog at the end of the quarter totaled $3 billion, a 78% increase from year-end 2024.
On a same-store basis, backlog increased approximately 50%. When you layer in our unsigned awards of $301 million and pipeline of future phase opportunities, which now exceeds $1 billion, we have visibility into a pool of work approaching $4.5 billion for Sterling.
Now, I'd like to discuss our segment results for the full year and fourth quarter in more detail. In E-Infrastructure, full-year revenue grew 59%, including 40% organic growth, and adjusted operating income grew 67%.
Adjusted operating margins reached nearly 25%, an increase of more than 120 basis points. This was driven by our shift towards large, mission-critical projects, where our superior project management and the ability to finish jobs on or ahead of schedule is extremely valuable to our customers.
In the fourth quarter, revenue grew 123%, including 67% organic growth. The data center market again was the primary growth driver in the quarter.
Additionally, our geographic expansion efforts are really paying off. Our Rocky Mountain site development operation, which is solely focused on mission-critical work, grew more than 150% from the prior-year period.
Adjusted E-Infrastructure operating income grew 91%. Operating margin for the legacy E-Infrastructure site development business were flat with prior-year levels.
Margins continue to benefit from our focus on large, mission-critical projects, and strong execution. The CEC acquisition is performing very well.
In the quarter, CEC revenue increased 21% from its prior-year fourth quarter, and margins were in line with our expectations. The Texas market, in particular, is very strong, and we continue to see tremendous opportunities ahead for both electrical and site development.
Our multiyear visibility in E-Infrastructure business remains excellent. The aggregate of our E-Infrastructure signed backlog, unsigned electrical awards, and future phase site development opportunities totaled more than $3 billion.
Mission-critical work, including data centers, large manufacturing projects, and semiconductor, represented 84% of E-Infrastructure signed backlog at the end of the year. Future phase work is predominantly related to mission-critical projects.
Moving to Transportation Solutions, for the full year, revenue grew 17%, and adjusted operating profit grew 66%, driven by strong market demand and the benefit of mix towards higher-margin services. Fourth-quarter revenue grew 24%, and adjusted operating profit grew over 100%.
We ended the quarter with Transportation Solutions backlog at $1.1 billion, an 81% year-over-year increase, driven by strong award activity and the conversion of unsigned backlog to signed backlog. Shifting to Building Solutions, full-year revenue declined 6%, and adjusted operating profit declined 23%.
In the fourth quarter, segment revenue declined 9%, and adjusted operating margins were 10%. Overall demand for homes has been impacted as potential buyers struggle with affordability challenges.
Even with the headwinds in Building Solutions, the strength of Sterling's diversified portfolio and strategy to focus on growth in high-margin end markets enabled us to deliver another fantastic year. With that, I'd like to turn it over to Nick to give you more details on some of our financial metrics and the 2026 guidance.
Nick?
Nicholas Grindstaff
Thanks, Joe, and good morning. I'll begin with our consolidated backlog metrics.
Our year-end backlog totaled $3 billion, a 78% increase from year-end 2024, or 49% excluding CEC. Combined backlog of $3.3 billion increased 81% from prior year-end, or 42% excluding CEC.
Fourth-quarter 2025 book-to-burn ratios were 1.64 times for backlog and 0.81 times for combined backlog. Moving to our cash flow metrics, cash flow from operating activities for 2025 was a strong $440 million.
We expect continued strength in operating cash flow in 2026 in both the legacy and recently acquired businesses. Cash flow used in investing activities for 2025 included $77 million of CapEx and $482 million for acquisitions, including CEC.
For 2026, we are forecasting CapEx in the range of $100 to $110 million, with the increase driven by investments to support growth and productivity. Cash flow from financing activities was $162 million outflow, primarily driven by share repurchases of $74 million at an average price of $168.72 per share.
In the quarter, we deployed $26 million into share repurchases at an average price of $310.09 per share. Remaining availability under the existing repurchase authorization is $374 million.
We will remain opportunistic in our approach to share repurchases. We are in great shape from a balance sheet perspective.
We ended the quarter with $391 million of cash and debt of $291 million, for cash net of debt balance of $100 million. Additionally, our $150 million revolving credit facility remained undrawn during the period.
Given our strong liquidity, we are in an excellent position to continue to take advantage of both organic and inorganic growth opportunities in the years ahead. Now, I'd like to discuss our guidance.
Our current backlog, visibility, and strong market tailwinds position us well for another great year ahead. We are initiating the following guidance ranges for 2026: revenue of $3.05 billion to $3.2 billion; diluted EPS of $11.65 to $12.25; adjusted diluted EPS of $13.45 to $14.05; EBITDA of $587 million to $620 million; adjusted EBITDA of $626 million to $659 million.
The midpoints of these ranges reflect strong year-over-year growth of 25% or higher for each of these metrics. Now, I will turn the call back to Joe.
Joseph Cutillo
Thanks, Nick. As we look to the future, we remain very bullish on the multiyear opportunity in each of our markets.
Our strong backlog, future phase opportunities, and conversations with our core customers on the size and number of future projects contribute to our confidence. In E-Infrastructure site development, we anticipate that the current strength in data center demand will continue for the foreseeable future.
We have discussed for some time that we're in conversations with our customers regarding how we can best support their strong multiyear capital deployment programs. As part of this, we are being pulled more rapidly into new geographies, including Texas and the Pacific Northwest.
Additionally, our projects are getting larger and are spanning longer time periods. In the semiconductor and manufacturing markets, there remains a very big pool of megaprojects on the horizon for the later part of the decade.
This would include planned semiconductor fabrication facilities. We believe that some of these projects are close to shore and will be awarded in 2026.
In e-commerce distribution, awards strengthened significantly in 2025 as large customers restarted their investment programs following the post-COVID buildout and correction. We believe that that momentum will continue into 2026 as these programs accelerate.
Together, these dynamics across our end markets support strong growth opportunities over a multiyear period. We have very good momentum in our electrical business for 2026.
Customer demand is very strong, particularly in the Texas data center market. We have a high degree of confidence in our ability to leverage the combination of our site development and electrical services to drive growth and margin expansion across the platform.
For 2026, we expect to deliver E-Infrastructure revenue growth of 40% or higher. This includes 20% growth or higher in the legacy business.
Adjusted operating profit margins for E-Infrastructure are expected to be in the 23 to 24% range. In Transportation Solutions, we're in the final year of the current federal funding cycle, which concludes in September of 2026.
We have built over two years of backlog and continue to see good levels of bid activity. For 2026, we anticipate continued growth in our core Rocky Mountain market.
The downsizing of our low-bid heavy highway business in Texas is progressing according to plan, resulting in some moderation of Transportation Solutions top line and backlog, which should continue to drive margin improvement as we move through the year. We expect Transportation Solutions revenue growth in the low to mid-single digits in 2026 and continued margin expansion.
In Building Solutions, we believe the business is well-positioned for growth over a multiyear period. Our key geographies of Dallas-Fort Worth, Houston, and Phoenix are all expected to see population growth, driving new home demand.
Additionally, there's an opportunity for share gain coming out of the down cycle. In the near term, we believe the current soft market conditions will continue.
We anticipate that Building Solutions revenue will decline in the high single to low double digits in 2026, and that adjusted operating margins will remain in the low double digits. As a reminder, from a seasonality perspective, our fourth quarter and first quarter tend to be slower than our second and third quarter, with the first quarter typically our lowest of the year.
On the acquisition front, we are continuing to look for acquisitions that are the right strategic fit to enhance our service offering and geographic footprint. We're seeing more high-quality acquisition targets in the market today than we did a year ago.
Moving to our full-year 2026 guidance, the midpoint of our guidance range would represent 25% revenue growth, 26% adjusted EPS growth, and 28% adjusted EBITDA growth. With that, I'd like to turn it over for questions.
Operator
Thank you. Ladies and gentlemen, we'll now begin the question-and-answer session.
Should you have a question, please press the *, followed by the 1 on your touch-tone phone. You will hear a prompt that your hand has been raised.
Should you wish to decline from the polling process, please press *, followed by the 2. If you are using a speakerphone, please lift the handset before pressing any keys.
One moment, please, for your first question. Your first question comes from Brian Brophy from Stifel.
Please go ahead.
Brian Brophy
Thanks. Good morning, everybody.
Appreciate you taking the question. I guess just wanted to ask about transportation awards in backlog.
It seems like it was a lot stronger than folks were expecting. Anything notable to call out there?
Were there any large awards worth highlighting? Thanks.
Joseph Cutillo
Thanks, Brian. Nothing in particular.
There wasn't one big giant project or anything. I think what people tend to get confused with is even though we're coming to the end of a funding cycle, only about 50 to 60% of the total funding has been spent.
We will continue to see good bit activity through that September timeframe as projects are continuing to be let, which will obviously be built for a time period after that. We feel very good of where we're positioned, and we like the bid activity.
Nothing major, just kind of good singles, doubles, and maybe a little triple now and then as we go forward. I also want to just remind you and everybody that at the end of the funding cycle, the world doesn't stop.
This isn't a toggle switch. Generally, what happens if they don't have the next funding bill in place is they will do an extension of the existing funding bill.
They generally or historically adjusted that for inflation. As a result, bids will continue to come out.
Brian Brophy
That's helpful. Then I guess just as a follow-up, you touched on this a bit in your opening comments, but hoping you could expand a little bit more, but just an update on some of the progress entering into Texas on the site prep side.
How is progress going kind of marrying that with some of the joint awards at CEC? Thanks.
Joseph Cutillo
We're really excited about the Texas market, one from the CEC side on what we're seeing for data center expansion electrical, but two, we're getting pulled very rapidly on the site development side. I think in the first half of this year, we're going to be able to talk about some very nice awards that take place in Texas.
We have been, I will tell you, what I believe ahead of schedule and more optimistic about the strength of putting these two together and the responses that we're receiving from customers. We're very pleased on the thesis is coming true.
I think we'll see some very good activity in the first half of this year that'll make everybody happy.
Brian Brophy
Great to hear. I'll pass it on.
Thank you.
Joseph Cutillo
Thanks, Brian.
Operator
Thank you. Your next question comes from Brent Thielman from D.A.
Davidson. Please go ahead.
Brent Thielman
Hey, thanks. Great quarter, guys.
Hey Joe, maybe
Joseph Cutillo
just
Brent Thielman
to tack on to Brian's question, if you could add a little bit more about how the pipeline has evolved at CEC since you've acquired it. Are the award opportunities getting a lot bigger?
Maybe if you could comment on kind of what you're doing or seeing already that might support a higher threshold for margins for that business going forward.
Joseph Cutillo
Yeah. The jobs are getting a lot bigger.
These data centers in Texas when we were joking at a recent leadership meeting, our team said, "Remember when we were so excited we got the first 100-acre data center?" This is just a few years ago.
We said, "Yeah, we thought it was the biggest project and all that kind of stuff." They said, "Yeah, we just started one in Texas and the parking lot is 100 acres," right?
Kind of put it in perspective. These things keep getting larger and larger, are having more and more.
These aren't data centers anymore. They're data campuses.
I think people get confused about that, and we'll have multiple buildings on them. CEC is got great traction.
Combined, the site development and CEC are getting great traction. We see margin improvements in a couple areas.
Obviously, as CEC moves more of their mix shift towards data center, that margin is historically better than the smaller kind of industrial commercial jobs. Also, as we're combining the exterior electric with the site development, we have already seen significant margin improvements with the small dry utility business we bought in Georgia last year.
The exact same thing will happen with CEC over a period of time. We're in the early phases of getting into those projects.
That's where I say I think we'll see some great progress in the first half of this year, and we'll start seeing some of that impact as we get to the second half of this year.
Brent Thielman
Okay. All right.
Thanks, Joe. Then, maybe just on the legacy site development margins, as you mentioned sort of flat here, obviously at great levels.
Maybe if Joe, you could just comment on why we shouldn't think they've peaked at this point?
Joseph Cutillo
Sorry, Brent. I misheard you.
You're asking about site development margins in the quarter? We don't see them going negative, that's for sure, especially as we're seeing larger and larger jobs come out.
We're also seeing some opportunities in the Northeast for some larger jobs that will help their margins improve significantly. One of the things we'll begin talking about more and more is we said in the script, our Rocky Mountain site development business grew 150% year-over-year.
We're really excited about that. One of the things we have that hurts our margins out in that area is we tend to have a little bit smaller and different equipment suite than we use on the East Coast.
We're going to be investing in some capital and doing some different capital planning that we think we can drive their margins up a fair amount as well just by duplicating exactly what we do in the Southeast and the East Coast. Then strategically, we'll continue to look at more vertical integration.
There's some leverage and productivity we can get out of vertical integration. As we move to a new geography, that's not where we start.
We kind of get our feet wet, get into the site development, execute that, gives us time to evaluate some of those players around the vertical integration, pick the best ones, and you'll see over the next 12 to 18 months us tucking in some of those around the U.S. I do want to add one more comment, though, on your CEC question on how rapid they're growing and everything else.
I would tell you if I had another 1,000 electricians in Texas and I have a much bigger number, I think we could put them to work in 30 days or less. When we bought CEC, they had a small modular build facility.
We just are in the process of signing a lease that triple the size of that. That will also help their margins so we can start pre-building more in a factory condition and ship those to the field.
Brent Thielman
Okay. Hey, great.
Thanks. I'll pass it on.
Operator
Thank you. Your next question comes from Manish Somaiya from Cantor.
Please go ahead.
Manish Somaiya
Good morning, Noelle, Joe, Nick. Congrats on the quarter.
A couple of questions from me. Maybe beginning with Joe, you talked about a billion dollars of high probability future phase work.
Can you give us a sense if that's tied to existing customers or programs, or is it completely new? How should we think about the expected conversion window?
Joseph Cutillo
First, that billion-plus is tied to projects we're actively working on today. That's real work.
That's what it's going to take at a minimum to finish out those projects. If you remember, as they continue to design, they release that work in a package.
We bid that next phase of work and then we execute it. It's very solid.
We can't technically call it backlog, but internally for capacity planning and everything else, it's backlog for us. It's tied to existing customers, but we're always getting a new customer here and there.
We're not just fixated on one or two. The lion's share of that are with the big name hyperscalers that everybody knows that have all announced their budgets, plans, and future forecasts, which are all up significantly.
I will tell you as we look ahead to the next 3 to 5 years and work with them on their planning, we don't see anything slowing down. If anything, we continue to see it accelerating.
Manish Somaiya
A question for Nick. As you guys scale up the E-infra business, how should we think about investments in working capital and free cash flow conversion?
Nicholas Grindstaff
We expect to continue to have strong free cash flow conversion. Conservatively, we're seeing free cash flow conversion to EBITDA in the 80% range or so, and that's a conservative number.
We expect that to continue as we move further into the E-Infrastructure space throughout the year.
Manish Somaiya
Okay. Then back to Joe, as we think about capital allocation, Joe, you mentioned obviously, you have a active share buyback program, $400 million, initiated back in November of last year.
You talked about M&A. You're talking about good assets coming on the market, which is interesting because I haven't heard that in a while.
Obviously, multiples are high. Maybe if you can just give us your sense of your priorities, is there a fourth leg that we should be thinking about to the Sterling business?
How do you sort of think about capital allocation, M&A, fourth leg, and why this whole abundance of good acquisitions, because we've heard that on a couple of calls and it's been a little bit surprising. If you can please help us understand that.
Thank you.
Joseph Cutillo
Our focus won't be necessarily on a fourth leg. It's really around when we step back and we look at data centers, semiconductors, pharma's coming, some other manufacturing that we see along with longer-term projects, right now, for the next 5 to 7 years, the best returns for us are going to be how do we grow, expand good services and geographic footprint within E-Infrastructure.
Now, that's not to say we won't, if the right fourth leg came along, we wouldn't aggressively go after it, but right now, the opportunities that are ahead of us and what our core customers are asking us for locations to go to, services to provide for the next 3 to 5 years, really has us focused on continuing to look for that geographic expansion of site development, and then also incremental electrical footprint and services and skills, and we will be looking at mechanical along the way as well as kind of a natural progression. That's where we're focusing.
Why do I think there's more quality businesses on the market? I think two things.
Multiples are certainly up some on the businesses. Two, I think a lot of these owners see this tremendous opportunity ahead of them, and they're not able to capitally fund the growth and they feel like they're going to miss the opportunity.
Frankly, if they don't team up with somebody big, they're going to be on the outside looking into this, and they're going to ultimately lose that work. They've been around this world a long time, and this is something that none of us have seen in our career from a standpoint of it's not billions.
I think it'll get to trillions of dollars of infrastructure spend that's coming in front of us that whether it's our yellow iron or our electrical skills or some of our other things fit right into.
Manish Somaiya
That's super helpful. Thank you, Joe.
Joseph Cutillo
Thank you.
Operator
Thank you. Your next question comes from Alex Rygiel from Texas Capital.
Please go ahead.
Alex Rygiel
Thank you, and good morning, gentlemen. When you talk about manufacturing and high-tech and fab plants, can you sort of help us to maybe understand how big that market opportunity could be sort of in the coming years?
Joseph Cutillo
We can start with the semiconductor stuff. I'm a believer that we're at the early innings of semiconductor.
I don't think we're going to see a major phase of semiconductor come on until 2030 or so, just with the length of time of the announced capital spend that it takes to get a project ready to break ground. In the meantime, there are a few projects that are going to be hitting here in the near future.
Put it in perspective, a data center job for us is kind of a three-year average, I would say. A semiconductor plant that are coming out will be closer to 7- to 10-year projects.
Instead of hundreds of millions of dollars, the total scope of those projects could approach a billion dollars. That's pretty sizable for us.
The pharma plants have announced multiple facilities around the country. Again, don't get confused when they announce it.
From the time they announce it to the time anything happens is going to be 3 to 5 years. It's just the cycle by the time you get the land, you permit it, you get utilities run.
They have to purchase equipment. Usually, that's specialty equipment, and it's not quick turnaround.
There's anywhere from 2 to 5 years of lead times depending on the parts and components in the industry. We see all of that coming.
In parallel, I will tell you our data center customers over that same time horizon are not slowing down. They're talking about bigger builds, more builds, and working with us to try to commit capacity and capabilities.
Also, when you see our geographic expansion taking place over the next 12 to 18 months, it's not necessarily because there's something there today. It's because we know something is coming in the future, and we're working with our customers to be prepared for that.
The Texas market is on fire, to say the least. It is unbelievable what is happening in Texas, and we're attacking that from the east and we're attacking it from the west.
Then we've got our CEC business right in the middle in Dallas. We feel very, very good about what Texas will add to our company over the next 3 to 5 years.
Alex Rygiel
Very helpful. Thank you.
Operator
Thank you. Your next question comes from Louie DePalma from William Blair.
Please go ahead.
Louie DePalma
Joe, Nick, and Noelle, good morning. Sorry that I joined the call late.
Joseph Cutillo
Good morning.
Louie DePalma
Joe, you previously on past calls you've discussed Sterling's entry into West Texas. Are you able to further expand into Texas to cover other key markets?
I know you said that you're attacking it from the east and attacking it from the west. Have you already won jobs on the east side of Texas and in other markets across the state?
Joseph Cutillo
Let me talk about the attacking from the east, attacking from the west, and then the market, okay? Just to make sure I don't create more confusion.
West Texas is growing very rapidly. I will tell you we're actively working and winning jobs in West Texas that we'll be able to announce in the first quarter.
What we consider east is kind of Dallas, Houston, that corridor. Not East Texas as the piney forests, there's not a lot going on there yet, maybe there will be.
When I say we're attacking it from the east and attacking it from the west, we're using our Plateau business to come and start hitting what we call East Texas, so that Dallas market. There's stuff going on up in Oklahoma in the near future that's coming out.
Then believe it or not, what most people don't realize is it's almost the same distance from Houston to West Texas as it is from Salt Lake City to West Texas, that's how big the state is. We're attacking the west using our Rocky Mountain resources and assets.
We'll be looking for strategic acquisitions obviously within Texas or closer proximity to continue to add assets and resources and capability and capacity. Does that help?
Louie DePalma
Yes, that was great, Joe. Should investors view 2026 as a year in which you're focused, in terms of your geographic expansion, you're focused mostly on Texas, or are there other data center and mission-critical geographies outside of the Southeast and outside of Texas that you can potentially expand into for 2026?
Joseph Cutillo
Yeah. I think in 2026, the lion's share of the data center growth will come in those areas.
There's some good activity taking place now in the Northeast. It's early.
We're excited about some projects up there. The two other markets that are out there in one, I think in 2026, you'll see us start moving more assets and resources to the Pacific Northwest.
Again, there are several projects that will probably be released in '27 up there that could be very exciting for us. The market we haven't figured out how to get into yet is kind of the Ohio-Indiana market.
That's always a potential for us. I won't tell you we're on the 10-yard line of getting in there or anything else, but that's another fairly sizable market.
When I step back and I just look at the Southeast, a few of the projects up in the Northeast, and Texas, man, you got the lion's share of the new stuff coming out, at least with our core customers, and the size of those projects really fit our profile, versus when you get into the Mid-Atlantic, there's a lot of number of data centers, but they're small and just don't necessarily fit our profile.
Louie DePalma
One final one related to this discussion. For your entry into new markets, is it reasonable to assume that the profitability in terms of the operating margins will be lower than the profitability for your core E-Infrastructure mission-critical business, such that as investors and the sell side as we're modeling, should there be any negative impact from expanding into Texas and expanding into the Northwest, or how should we consider that?
Joseph Cutillo
I think, depending on if we move equipment suites as an example from the Southeast to Texas, we're going to see the exact same margins. We've seen a little lower margins, same pricing, same kind of process, a little bit lower margins in our Rocky Mountain, not because of the market, just because we're ramping up that equipment profile.
Remember, we kind of converted highway assets plus some large assets to get them underway. As we continue to build that out, those margins will grow.
Where I think we will see when we look at acquisitions as an example, most acquisitions margins are a little bit lower than ours, right? We believe that after we get those acquisitions in our footprint, introduce our processes, our procedures, our technology, and do those sort of things, we can continue to grow those margins up to where we are.
Just the other thing to keep in mind, Louie, is our projects, remember the multi-phases, anywhere 3, 5, 7, they always start out at a lower margin, and those margins improve based on productivity and what we're able to do staging earlier phases to help productivity on the future phases.
Louie DePalma
Awesome. Thanks, Joe, and thanks, everyone.
Joseph Cutillo
Thank you.
Operator
Thank you. Your next question comes from Adam Thalhimer from Thompson Davis.
Please go ahead.
Adam Thalhimer
Hey, good morning, guys. Nice quarter.
Joseph Cutillo
Thanks, Adam.
Adam Thalhimer
Joe, can you talk more about the CEC modular expansion? Curious what that'll take you to on a square footage basis, and what exactly are you doing modularly versus in the field?
Joseph Cutillo
Yeah. What our simple take on that is, we're not the only ones doing modular, but anything we can take out of the field and prefab to move into the field reduces the number of electricians we need on that site, right?
It also improves productivity and cost. The new facility is over 300,000 square feet.
I will tell you that we're looking at does it or doesn't make sense to have multiple facilities throughout the U.S. that can make these components.
We're doing everything from the exterior piping and conduit around the duct banks to the actual cabinets that go into these centers. We're looking at how do we continue to expand that capability and growth.
It's pretty exciting because it really, when you run the numbers, it's significant on what it frees up for capacity and how it positively impacts your margins.
Adam Thalhimer
Future of construction.
Joseph Cutillo
What's that?
Adam Thalhimer
I said I guess it's the future of construction.
Joseph Cutillo
Dude. I think we will see, regardless of us or our space or other spaces, you're going to continue to see modular activities grow.
Is the labor pool just gets tighter and tighter, it's the most logical thing to do, frankly. Then
Adam Thalhimer
just lastly, I wanted to see where your head was at on the residential biz. Does it make sense to do an acquisition there when multiples might be more depressed, or does it just make sense to let that play out?
Joseph Cutillo
Yeah. I'd like to tell you there's light on the horizon.
I think it's going to be, tough certainly first half of 2026, and there's nothing positive that's happening to spark or drive the residential business turnaround. I'll also warn everybody that once it does turnaround, there's three or four months of inventory on the ground that these builders are going to sell before we start seeing new builds start, right?
That's just a fact. You're not far off.
I will tell you, if the right acquisition came along in residential and multiples are down, and by the way, their earnings are down. We feel optimistic long-term because the last time when we went back and looked at Tealstone coming out of the last downturn, they picked up significant market share on the back half of this, and we think we'll pick up market share coming out of this, especially in the Houston and Arizona markets.
If we found the right acquisitions, we wouldn't shy away from them, and we'd get them at a huge discount and we'd look really smart 18 months from now.
Adam Thalhimer
Perfect. Thanks, Joe.
Joseph Cutillo
Thanks, Adam.

Thank you. Your last question comes from Julio Romero from Sidoti & Company.
Please go ahead.
Julio Romero
Thanks. Hey, good morning, Joe, Nick, Noelle.
Wanted to stay on the topic of these projects getting bigger, as you said, Joe, they're not even data centers anymore, they're data center campuses. As these mission-critical projects get bigger, more complex, is the mix of above-ground work versus underground infrastructure changing at all, and if so, is that mix shift margin-accretive?
Joseph Cutillo
I won't tell you we've seen any significant shift on above ground versus below ground. I think what we will see, kind of the next generation of these projects are going to have self power generation on them.
That will create more development opportunities on these, because if you have a power plant, you got all the underground, whether it's water, utilities, you got the electrical coming in, all that stuff. We think that the size and scope of these projects not only in physical size will get bigger, but the amount of stuff that we will touch will continue to grow.
Those projects really won't start hitting till '27 '28. We may see one this year, but that's the lion's share.
It also opens up opportunities to look at other goods and services that we could add to those projects.
Julio Romero
Got it. Does that change at all if the mix within mission-critical does skew over time to semiconductor and advanced manufacturing?
Joseph Cutillo
Yeah. No, there's not a tremendous difference.
Obviously, you got duct banks in the data centers, but what people don't realize is any of these facilities literally has thousands of miles of underground pipe and wire and everything else. It's an underground city.
For us, we're not concerned if the mix shifts more towards semiconductors and away from data centers or more towards manufacturing. We've got more data on the site development side, obviously, but we've seen comparable margins.
That's the beauty of the model we have. Now with electrical and as we continue to expand the footprint of electrical and capabilities, our stuff's fungible.
Big projects obviously are much better for us, but we don't really care if it's a data center or a chip plant or a large automotive facility or a battery plant.
Julio Romero
Very helpful. I wanted to ask how Sterling is positioned amongst other specialty contractors with regards to AI-driven tools.
As these tools kind of become more adopted across the industry, Joe, how are you thinking about staying ahead of competitors? I'm sure some of those competitors would say they're probably using AI to narrow the gap of reliability, or maybe scale versus Sterling.
How do you see Sterling position in that context, and could you be using these tools to maybe widen your differentiation versus some of these peers?
Joseph Cutillo
Yeah. I don't know where our peers are.
I could tell you where we are. I think people would be shocked at what we've done and what we're doing in and around AI and how we're tying that to not only the estimating and bid process but the project execution.
We did three pilots last year. To say the teams were excited is an understatement.
When we first started them, everybody said, "How is AI applicable to what we do?" Remember, we're running drones, we're running all kinds of analytics off our equipment.
We're now tying all that into project management and making things happen faster. Remember, our capacity constraint in site development is project managers.
We picked up somewhere between 15 to 20% of incremental capacity on project managers just from our first AI project. We've got six AI projects underway right now.
I will tell you when people talk about, "Well, is AI real?" and all that, I always say if guys like us are running very quickly at this and our guys every time they touch it, they come up with four or five other things that we can incorporate, which will improve the efficiency, the effectiveness, the quality, and just as importantly, there's some really cool things we're doing on the safety side with this that will help make our employees even safer than they are today.
Julio Romero
Absolutely. Thanks again for taking the questions.
Joseph Cutillo
