A slide presentation is provided as a companion to our remarks and is posted on the Investor Relations section of the company's website found at ComfortSystemsUSA.com. Joining me on the call today are Brian Lane, Chief Executive Officer, Trent McKenna, President and Chief Operating Officer, and Bill George, Chief Financial Officer. Brian will open our remarks.

Thanks, Julie. Good morning, and thank you for joining our call today. We had a fantastic quarter and a strong start to 2026, driven by continued outstanding performance by our field teams. Our same-store revenue grew by 51%, and quarterly gross margins hit a new all-time high. We earned $10.51 per share this quarter, more than double our strong first quarter in 2025. We also entered the quarter with record backlog of $12.5 billion, reflecting persistent demand, including strong demand from our tech customers. And we entered the second quarter of 2026 with total backlog that is $5 billion higher than it was one year ago. We also announced another increase to our quarterly dividend to $0.80 by adding $0.10 per share. And we remain committed to consistently rewarding our shareholders while maintaining a strong balance sheet. We'll discuss our business and outlook in a few minutes, but first I will turn the call over to Bill to review our financial performance.

Thanks, Brian. So, yeah, we had a really great start to 2026. Our first quarter revenue was $2.9 billion, an increase of 56% compared to last year. Same-store revenue increased by 51%, or $943 million. Revenue increased in both segments, with an increase of 88% in our electrical segment, while our mechanical segment revenue increased by 47%. Both segments also continue to benefit from strong demand in the technology sector. Although we will face higher comparables in the second half of 2026, We believe same-store revenue for the full year 2026 is likely to be higher than 2025 revenue by percentage growth in the mid to high 20% range. It was $754 million for the first quarter of 2026, which is $351 million higher compared to a year ago. Our gross profit percentage grew to 26.3% this quarter, compared to 22.0% for the first quarter of 2025. Gross profit in the quarter benefited from $43 million in favorable developments on late-stage projects, including change orders, especially in our mechanical segment. Quarterly gross profit percentage in our mechanical segment improved to 26.9% this year, compared to 21.7% last year. Margins also moved up by almost two full percentage points in our electrical segment to 24.9% as compared to 23% in the first quarter of 2025. We currently expect that gross profit margins will continue in the strong ranges that we have averaged over the past several quarters. SG&A expense for the quarter was $269 million compared to $195 million in the same quarter of 2025. as we grew people and rewarded our busy teams in markets across the nation with the large jump in revenue SG&A as a percentage of revenue was 9.4% this quarter compared to 10.6% in the prior year our operating income increased by 132% from 209 million in the first quarter of 2025 to 486 million for the first quarter of 2026. With improved gross profit margins and SG&A leverage, our operating income percentage increased sharply from 11.4 percent to 17.0. Quarter to date effective tax rate was 23.2 percent compared to 18.6 percent in 2025. Our prior year effective tax rate was lower due to interest we received on a prior year tax refund. We expect our full year effective tax rate to be around 23 percent. After considering all these factors, net income for the first quarter of 2026 was $370 million, or $10.51 per share. And that compares to net income for the first quarter of 2025 of $169 million, or $4.75 per share. EBITDA increased by 116 percent to $524 million this quarter, from $243 million in the first quarter of 2025. And our trailing 12-month EBITDA at the end of March 2026 is $1.74 billion. Our free cash flow was a positive $242 million in the first quarter. Capital expenditures were $147 million in the quarter. CapEx was 5.1% of revenue, compared to 1.2% in 2025. Expenditures included a large modular assembly building purchase in Texas and other investments in our modular capabilities. We plan similar capital investment for the remainder of the year and we estimate full-year capex will be in the range of 5% of revenue. So happy to note that during March we entered into a definitive agreement subject mainly to regulatory approval to acquire another highly skilled electrical contractor. The transaction is expected to close in early May and we expect our new partner to initially contribute annualized revenues of roughly 250 million with EBITDA margins in the 8 to 10% range

that's what I've got Trent thanks Bill Brian has asked me to comment on our business operations and provide an assessment of our outlook backlog at the end of the first quarter was a record 12.5 billion a same store sequential increase of just over 500 million and a remarkable same-store year-over-year increase of 5.3 billion first quarter bookings were especially strong in the technology sector our companies are collaborating more than ever to deliver superior mechanical and electrical solutions for our customers our revenue mix continues to be led by the industrial sector with that sector accounting for 75% of our volume in the quarter. Advanced technology dominated by data center work increased to 56% of our revenue, and advanced technology remains the largest driver of pipeline and backlog. In institutional markets, including education, health care, and government are also solid comprising 17% of our revenue. The commercial sector now accounts for about 8% of revenue with most of our commercial sector revenue flowing through our service activities. The construction accounted for 90% of our revenue with projects for new buildings representing 75% and existing building construction 15%. Modular revenue was 17% of total revenue in the quarter We are on track to have 4 million square feet of modular capacity by the end of 2026, and we are actively evaluating additional capacity investments. We include modular in new building construction and in our mechanical segment. Service revenue was up 8% this year, but with faster growth in construction, service is now 10% of total revenue. Service profitability was strong this quarter, and service continues to be a growing and reliable source of profit and cash flow. Before we turn the call over for questions, I want to join Brian and Bill and the team here in Houston in thanking our over 23,000 employees for their hard work and dedication. Comfort Systems USA's success is a direct result of the people that serve our customers every single day. We're now going to turn this call back to Lateef for questions. Thank you.

Thank you. As a reminder, to ask a question, you will need to press star 11 on your telephone. To remove yourself from the queue, you may press star 11 again. Please stand by while we compile the Q&A roster. Our first question comes from the line of Adam Thalimer of Thompson Davis. Your line is open to Adam. Hey, good morning, guys. Great quarter.

Thanks, Adam. Good morning.

Bill, the CapEx forecast for the rest of the year, can you give a little more color on what that is? And is that more geared towards projects you've already booked, or are you getting ready to handle future orders?

So, you know, just as it's been for the last, really, couple years, the answer to that question is all of the above. So we did buy our biggest building ever in Houston in the first quarter. Once you buy them, you then have to spend tens of millions of dollars putting cranes and robots and various turntables and paint booths and stuff like that into the building. One of the reasons we're buying these buildings now is because we've become a lot more automated and we put so much money into the building that it doesn't make sense to make those big investments into a building you don't own. We are looking at other building investments later in the year. We are, you know, this building was part of getting to the 4 million square feet. But, of course, you know, we definitely have the demand from our existing largest customers and from new customers that we're doing, you know, trial, trial, large, very large trial orders with that additional capacity if we if we become comfortable with that later in the year.

Okay. And then the other one for me, geographically, I'm curious where you are seeing more of the data center demand these days and how that matches up with your capabilities.

I would say by far, in a way, the biggest epicenter of demand is Texas, right? And it's really, really strong. But we're seeing data centered. I don't know that there is a strongest place. I mean, there's certainly the Mid-Atlantic, you know, Carolinas, and Virginia continue to have a ton of activity. And then you've got stuff in places like Mississippi and, I don't know, up in the Upper West, there's stuff going in. So it's just kind of amazing just the sheer, you know, the sheer sort of stand of it.

And, Adam, we can handle the geographies because we have a significant traveling workforce. So, you know, whether they want to build them, we pretty much can accommodate them.

Great. All right. Thanks, guys.

Thank you. Our next question comes from the line, Blair. Your line is open, Tim.

Hey, this is Sam Cuff from On4Tim. Thanks for taking our questions here. You know, I want to dig a bit more into your new guidance here. Mid to high 20% organic growth for the year would obviously be a great result. It does imply, though, a fair amount of growth moderation through the year. And I understand the comps get a bit harder here, but you had great momentum in the first quarter, and your backlog growth continues to outpace revenue growth. I guess given this, I think it would be helpful for us to understand a bit more or how you came to the mid to high 20% organic growth rate for the year here?

So, you know, at Comfort, the way that we come up with this is very organic. We get projections from our field, and we, you know, we know what our work that's committed is. We obviously, if we give guidance, it's at levels that we feel, you know, have very good reasons to believe are extremely achievable. You know, having said that, you know, I'm not sure I agree with you that, you know, to get to something like the I-20s or something, you've still got to be above 20% on average for the next three quarters. And I know you acknowledge this, but we had some really big revenue quarters in the third and fourth quarter. And then the last thing I'll say is revenue is never our goal. Our goal is profit. And so, you know, we just want to make sure that we take the amount of work we can do, that we get paid fairly for the unbelievable productive capacity that we have, and that the risk that we take is also well compensated.

Yeah, that makes sense. That's helpful. Maybe another one on the data center topic here, but, you know, several states have begun talking about data center bans or even limiting access to power. I guess I'm wondering, for the regions you're more exposed to on the data center side, are there any pieces of legislation or proposals that, you know, you're actively tracking or closely following that could put some of your projects or backlog at risk?

At this point, no. There's no states where we're involved that have proposals out that we've been tracking. And they just don't impact our geography. And then, you know, the other thing I'd add to that is anytime a large project that has a big footprint footprint is getting put into some sort of community or state and there's a lot of build occurring. There's always been pushback on these things historically. So this is something that we've been able to, you know, work around for years. It's not, I don't think, a high level of concern. Additionally, we have a very good nexus of work in the states that are not currently in any sort of discussion. In fact, they're encouraging the build out in the states that we are primarily focused on right now with where our geographies are. So, you know, long term, something we'll continue to, you know, keep an eye on, but it's not a pressing concern in the current environment. And as we sit here today, the demand, the data says, still exceeds the supply.

Got it. That's very helpful, guys. Appreciate it.

Thanks.

Thank you. our next question comes from the line of Sanjita Jane of KeyBank Capital

Markets your line is open Sanjita great thank you so much can I ask one on the electrical acquisition that you just mentioned maybe the geography of that acquisition the core and markets it participates in or any other

information that you can help us with so this is a company that is right in our sweet spot. It's the kind of company that is incredibly strong in its market. Its market is in the West. I can't get too specific because obviously until we announce it, you don't need to know about it before the people there know about it. But it's in a core market that we love where we already have a mechanical. It's going to be a great acquisition. Got it. Thanks. And

appreciate your giving us more details on how you came up with the guidance for this year. So as you were planning for your guidance for the remainder of the year, can you talk about where you found the biggest change points for growth? Is it labor? Is it procuring the equipment that you need? Or maybe it's something else, any color would be helpful?

I mean, it's always and forever for us. It's labor. that may change someday but as of today we have unbelievable workforce but they can only do so much work and you know they basically tell us they take the work that they can confidently deliver for their customers if you look at our same-store growth it's unbelievable what these our workforces are accomplishing the you know the additional work they're able to take our our head count if you look at the head count in the first quarter of 2025 it's a it's three or four thousand people higher in the first quarter of 2026 depending whether you include or don't include workers that aren't always w2 employees that's a very very big source of that increase in addition our materials and equipment as a percentage of our revenue is up by a couple hundred basis points and that drives but a lot of that increase in headcount last year happened from the first to the second quarter so a lot of the a lot of the sort of the 23,000 plus level that were we were we were much closer to our current level of employment by the end of the second quarter last year then you know we were We had a great spring hiring season. We're just comfortable mid to high 20s. You know, obviously, if you average that, it's well above 20% on average a quarter for the next three quarters. You know, in the real world, what will happen, we never know, but we feel like we should give you guidance based on what we see and we're confident in.

Great. Appreciate it. Thank you.

Thanks, Anita.

Thank you. Our next question comes from the line of Josh Chan of UBS. Your line is open, Josh.

Hey, good morning, Brian, Bill, Trent, Julie. Congrats on a really good quarter.

Hey, thanks, Josh.

I guess I was wondering if you can talk about the project pipeline, so basically the future projects that could enter the backlog in the future. You know, I guess I'm asking this because, you know, book-to-bill this quarter was like 1.2, which is pretty normal for Q1. But for the last four quarters, you have been running massively strong book-to-bill. So I'm just wondering if there's cadence change or how you're thinking about the market.

Yeah, so, hey, Josh, the high-level answer is the pipelines are still very full, very strong, coast-to-coast. So there's no issue with the pipelines and availability of work. What I and we're really happy to see is we're maintaining our discipline and the selection of work we're taking. There is no sense over committing ourselves and work that we can't do properly. So I think the way we're approaching this is the way we've always approached it, is just to make sure we can deliver a good product and service to our customers. And that means staying within our lanes, the work we're taking is in our wheelhouse, and it's evidence in the margins we're delivering. So, back lines are good, and we're really comfortable with the backlog we have.

In the 30 years I've been watching this industry, almost the whole time, whenever you saw deceleration or whenever you saw limitations, until the last couple years in sort of the ability to convert revenue or book work. It was a demand issue. Today, I think it's really important for people to understand that it's a supply issue. There is plenty more work we could take if we could possibly do it. And so it's very, very hard to really internalize that paradigm after, you know, it never having been true, you know, in living memory. But today, when you see somebody like a prognosticator like McGraw-Hill or FMI revise downward their number for next year, especially if it's anything remotely close to the super cycle and in the kind of markets we're in, in the mid-Atlantic and the southeast and Texas and the really, really hot Rocky Mountain states, it is not that suddenly people don't want to build buildings. It's that only a certain amount of buildings can be built, and that's what's going on.

Okay. Yeah, great, Carlo. Yeah, thanks, Brian and Bill. And then maybe my second question on CapEx. So I know that for the modular capacity, you've historically leased your, you know, buildings, and you mentioned why you're purchasing them now. I guess, like, what does that mean in terms of what you think about the durability of the cycle now that you're willing to kind of actually put your own money into the buildings? Does that suggest you have much more confidence in the outlook?

Well, so for one thing, you know us well enough to know that we don't go invest in buildings without being very, very confident that we have customers for those buildings. And for many of these buildings, we are insisting as a condition of us committing our capacity that customers make multi-year commitments at volume levels. And, you know, that allows us to give them better pricing, right? We would have to demand higher pricing if we were certain that the capacity we were building wouldn't have a longer period to pay off. And it also tightens our relationship with these customers, right? We try to find out what they need, and we try to help them every way we can to get what they need.

Yeah, that's great. Yeah, thank you for that, and thanks for your time.

Thank you.

Thank you. Our next question comes from the line of Brian Brophy of Stiefel. Your line is open, Brian.

Yeah, thanks. Good morning, everybody. Congrats on another nice quarter here. I wanted to ask about the $43 million change order close-up benefit you mentioned in your opening comments. Just any more color on what drove that benefit this quarter? And I guess to the extent, was this more of kind of a one-time benefit from your perspective, or is this more of a reflection of the environment we're in with favorable T and Cs, and is there an opportunity to continue to get these kind of benefits more consistently moving forward?

So I'll talk about it numerically, and then if Trent wants to, he's the one who would be able to talk about sort of what's happening in the jobs. But essentially the reason we called this out, put it in the MD&A, quantified it, is because there really were a few unique things that we don't believe are just business as usual. We had late-stage jobs where we received change orders. You may recall we had something like this two or three quarters ago where we collected some money on a job based on a negotiation that we didn't expect, where we see something that, like, we get the question from shareholders like you, was there anything special in the quarter? We like to be able to answer that truthfully, so to answer it truthfully, we have to disclose it in this forum, and those really are not repeatable things. Things like that can happen in the future. They have happened in the past, but they don't happen every quarter. If you take that $43 million and you back it out, it's almost a dollar a share, and it takes our gross margin, and it puts it sort of at 20 something like 25.2 which sequentially is much much closer much closer it's still very high but it's much closer to what you would expect in a first quarter and so we just you know we just felt like good disclosure would be you know we don't like to give information and where but we did we thought we do do that when we feel like we we owe it to you guys so that's hopefully that helps

it was just a it was just a mixture of change orders from a d scope and then And also, additionally, some really favorable closeouts on some work that was new to the operating companies that were performing it. And, you know, they just recognized disproportionate gains at the end of the job because of their ability to deliver. It's really a credit to the teams that were working so hard to make sure that they delivered for their customers. So that's what it boils down to.

Yeah, that's helpful. And then I guess just looking at electrical growth, you know, it was about 80% organic this quarter. It's been around that range for a few quarters now. You know, I realize some of that is price and productivity, but obviously headcount is a big part of that as well. I guess maybe just touch on where are you finding all these electricians and just how sustainable do you think your ability to grow headcount at this pace is?

Well, I think we're finding them, you know, everywhere. But as we've said, we're a really good place to work. We pay people well. We do a lot of training. We have a lot of work that attracts people. So the type of work we're getting is attracting a lot of electricians throughout the country. Can we keep the pace? We're going to try to. We're full-court press on recruiting, hiring, and so far we've had good luck doing it. But we'll continue swinging away at it, Brian.

Understood. I'll pass it on.

Thank you. Our next question comes from the line of Julio Romero of Sidoti and Company. Please go ahead, Julio.

Hey, good morning, everyone. Bill, you mentioned earlier that Comfort's goal and focus is on the gross profit dollars and still the 26.3% gross margin percentage you put up this quarter eye-popping, even backing out the $43 million change order, as you said, $25.2 million is still very strong. just, you know, asking about the sustainability of those gross margins on a core basis going forward. And then kind of related to that, as you take on these additional larger projects, are we seeing any change in the mix of activity versus cost pass-throughs that flow through the revenue line that might cause gyrations in the gross margin line on a percentage basis?

So the answer to the second one is no. Actually, we're seeing, if anything, more uniformity in the work that we're taking and more repeatability, which is one of the reasons that we're, you know, that we're doing so well. We're able now to sort of our parties to make sure that we do work with people. We've done similar work with people who have proven that they're constructive when issues come up. And so I would say, if anything, we with that sort of structural internal cadence. As far as the ability to maintain the margins, you know, we said we expect to stay at the high margins that we've averaged over the last several quarters, for the next several quarters. You know, everything else we said on this call is super supportive of our ability to extract high margins and to get rewarded for the work we do. And I, you know, as much as, you know, Brian Lane likes to complain and cry, we're in a pretty good market and we got the best teams in the world and so at some point we just have to take the win. I want to keep crying

Bill. And Julio, the only one thing I'd like to tack on to that is just we wouldn't be achieving these types of results if it wasn't for the teams in the field and their commitment to constant improvement. It's really our companies, especially our company's field leadership that's fostered a culture of continuous improvement and that is it shows in these results, right? It's just hats off to the teams out there that are making this happen.

Really helpful and insightful. Thank you for that. And then secondly, you know, related to kind of your point earlier, Bill, about partnering with repeat customers and choosing your customers and, you know, repeat in-use customers, I kind of have a broader question about the longer-term revenue opportunity on these technology construction projects. You know, is there an opportunity or have you thought about an opportunity to expand wallet share with the owner-operator of the data center beyond the initial construction scope by cross-selling any adjacent solutions related to monitoring sensors or just overall optimization of the data center?

I think there's a wonderful maintenance and service opportunity that, you know, think about the installed base that's being created and then sort of think about the companies that are doing it, the advantage we have in understanding it. And even if you take our modular stuff, the modular units that we build are built to be maintained. They're built to have great accessibility to the parts and pieces that we'll need in the future. There's a lot of consideration that's going into the work we do today about in what ways things might need to be retrofitted in the future. For example, if they were to achieve chips that do not need to be cooled as much, then at some point you could keep high levels of cooling, but you would still have to add electrical capacity in order to add additional servers. And I know for a fact that in some cases, consideration is being given much more than it has in the past about the ways that the technology might change in the future and making sure that you can't exactly future-proof stuff but you can give yourself options, and a lot of that's happening. It's really one of the great advantages of doing something on this scale. And for us, right, doing it in so many states with so many great companies that talk to each other, we can bring something to our customers that is pretty close to unique.

Fascinating answer. I'll pass it on.

Thank you. I would now like to turn the conference back to Brian Lane for closing remarks, sir.

Thank you. In closing, I really want to thank our amazing employees again. We are truly fortunate to have the people that work at all levels of this organization. It's a real privilege to be here. We appreciate all your interest and comfort systems, and then we look forward to having a really strong 2026. Thanks again, and I hope you all have a great weekend. Thank you.

This concludes today's conference call. Thank you for participating. You may now disconnect.
