Son Vann
Vice President of Investor Relations
Thanks, Daniel, and good morning, everyone. Welcome to Legion's second quarter 2026 earnings call. With me today are Jeff Sprau, Chief Executive Officer, Stephen Butz, Chief Financial Officer, and Steve Hansen, Chief Operating Officer. This morning we issued a press release that covers our second quarter 2026 financial results and posted a presentation that accompanies the earnings release. All materials can be found on the investor relations section of the company's website, wearelegions.com. Before we begin, I want to remind you that comments made during this call contain certain forward-looking statements and are subject to risk and uncertainties, including those identified in our risk factors contained in our SEC filings. Our actual results could differ materially, and we undertake no obligations to update any such forward-looking statements. During this call, we will refer to certain non-GAAP Thank you, Son, and thanks everyone for joining today to discuss our second quarter performance and current outlook for legions.
Jeff Sprau
Chief Executive Officer
As we have talked about on our past earnings calls, the demand environment for mission-critical building systems continues to be robust. This strength is evident in the exceptional growth in both our record revenue and backlog. Excluding the impact of acquisitions, organic revenue growth was nearly 60%, while backlog and awards grew organically by over 35% year over year. And when we include acquisitions, Revenue more than doubled with similar growth in total backlog. As you would expect, the data center and technology end market led this growth. Recent discussions with our data center clients suggest continued risk demand over the next several years. These discussions suggest no change in the pace of activity from what was discussed at the beginning of the year, and in some cases, speed to market has actually accelerated. Within the data centers and technology end market, it's worth noting that this sector also includes semiconductors, an area where we're also experiencing solid revenue growth. Our growth extends to other core markets as well, including life science and healthcare, education, and state and local government, all of which are experiencing solid high single to double digit organic revenue growth year to date. Also worth noting is our activity level in manufacturing, which is embedded in our other end market category. While this end market represents less than 3% of our overall revenue base, it is experiencing very strong revenue growth and is now about equal to the size of our mixed-use market. We expect reshoring to favorably impact our manufacturing end market in the coming years. As I mentioned before, I really like our exposure to diverse end markets, understanding that growth rates between markets can ebb and flow. By intentionally focusing on attractive, higher growth, target-rich sectors that align well with our mission-critical services, this diversity can offset, to a degree, some of the volatility of each market. We, of course, value every client relationship and strive to deliver exceptional outcomes on every project. This customer-first philosophy has served us well for decades, and in some cases, over a century, and is the foundation of the reputation, trust, and long-standing partnerships that we've built across our broad client base. On our quarterly results, Stephen will go into greater detail, but at a high level, total revenue of $1.3 billion increased by 111% year-over-year, and over half of this growth was organic. in a similar fashion, adjusted EBITDA grew by 114% year-over-year. Adjusted EBITDA margins expanded by almost 90 basis points sequentially. Total backlog and awards ended the quarter at a record $5.7 billion, up 105% year-over-year and 5% sequentially. We saw strong growth in backlog in both segments, notably Our engineering segment backlog grew by 27% year-over-year and 11% sequentially, mostly on an organic basis. Our consolidated book-to-bill ratio for the three months ended June 2026 was 1.2 times. Book-to-bill over the last 12 months was 1.4 times. As our markets evolve, particularly the data centers and technology markets, The award sizes have grown quite significantly. In fact, it's not uncommon these days for some of the larger bookings to exceed $100 million. These bookings can come in waves with some of the large projects burning pretty quickly. All of these factors can create some volatility in our quarterly net bookings and book-to-bill ratio, which is why we like to also look at the book-to-bill ratio over a 12-month period. We feel confident in our ability to continue to grow total backlog as the year progresses based on what we see in our opportunity pipeline. Our confidence in the future is also reflected in our revised guidance for full year 2026, which Stephen will walk you through shortly. To support the execution of our growing backlog, we continue to grow and invest in our workforce. Total employee headcount is now close to 11,000 at the end of July. including approximately 8,000 skilled technicians and craftspeople. As demand for our services continues to grow, we expect to further expand our labor force. Combined with our continuous efforts to drive operational efficiencies, optimize workforce scheduling and stay selective on our project pursuit, these efforts position us to better serve our customers going forward. Our fabrication footprint is a big part of our efficiency efforts. During the second quarter, we grew our fabrication capacity by about 200,000 square feet, putting our current capacity at 1.5 million square feet. And we expect to add another 100,000 within the next couple weeks and are looking at opportunities to expand even further. There are a lot of efficiencies that we can implement in our square footage through the use of advanced tooling, automation, optimization of floor spacing, and flexibility with labor shifts, among other levers. I should also note that the capacity expansion is based on existing demand that we see in our backlog. When adding this incremental capacity with the organic expansion that we've completed over the past year and the capacity that came with Bowers, we will have grown our fabrication capacity by over a million square feet across our key geographies. Our third-party fabrication demand continues to be concentrated on data center and, to a lesser extent, pharmaceutical clients. More recently, we've seen increased demand from semiconductors and memory chip clients. Before handing the call to Stephen, I want to point out the continued improvement to our net leverage. During our IPO process, we heard from the investment community about the importance of having a strong balance sheet and, as a result, prioritize the entire IPO proceeds toward debt reduction. This allowed us to exit the IPO at three times net leverage last September. In just three quarters, we've essentially cut our financial leverage in half, with pro forma net leverage now standing at 1.5 times. This reduction was achieved during a period when Legions completed our largest acquisition in company history, namely Bowers in the DMV. And at 1.5 times net leverage, we're in a great financial position to pursue other attractive, impactful acquisition opportunities that meet our strategic and financial objectives. Our M&A pipeline has never been as active as it is today. and of course we'll be disciplined with our evaluation of these opportunities.
Stephen Butz
Chief Financial Officer
With that, let me turn the call over to Stephen. Thank you Jeff and good morning everyone. I'll begin with a review of second quarter 2026 results in comparison to second quarter of 2025. Following my review of our historical results, I'll provide a brief update on our current guidance and discuss our balance sheet and liquidity position before turning the call back to Jeff. Starting with the second quarter of 2026, we generated revenue of $1,262,000,000, an increase of $663,000,000 or 111% from the year-ago quarter. The Bowers Group acquisition contributed approximately $300,000,000 of revenue. Excluding Bowers, our revenues grew by nearly 60% year-over-year. Looking at our latest quarterly revenue growth at the segment level, Starting with engineering and consulting, segment revenue increased by 6% to $207 million, which was mostly organic. Program and project management service revenues grew by 17%, with particularly strong growth in state and local government as we're working on several large projects in Washington, D.C., South Carolina, Colorado, and Minnesota. We also saw strength in data centers and technology. Engineering and design revenues declined by 4%, with the decrease mainly attributable to soft demand from our sustainability consulting services for mixed-use clients, primarily large owners of commercial real estate. Our sustainability consulting business has experienced softer market conditions over the past several quarters, reflecting both broader challenges across the commercial real estate sector and evolving client demand for these services. Because impairment testing reflects our longer-term forecast, but the near-term is often underpinned by customer contracts, the downward trend we've seen in backlog for those services was a key consideration and led to our decision to impair goodwill and other intangibles for this business during the second quarter. We still have conviction in the long-term value that our sustainability consulting services can deliver to clients, particularly in an environment with rising energy costs. Turning now to our larger installation and maintenance segment, segment revenue of $1,055,000,000 increased by 162% versus the year-ago quarter. Over half of the segment's revenue growth was organic, while the remainder was largely attributable to the addition of Bowers. Installation and fabrication services drove the majority of the segment growth, increasing by 189% year-over-year due to both strong organic growth and, again, a meaningful contribution from Bowers. With respect to the organic growth, data center and technology was a key driver. But our other core markets, such as life science and healthcare and education, also saw solid organic growth in the low to mid-teens. And state and local government growth was also very strong, though from a lower base. Maintenance and service revenue increased by 58% year over year. Excluding the impact of Bowers, this service line delivered organic growth of nearly 20%. The high growth rate was spread across essentially all of our end markets with the exception of mixed use. Turning to reported gross profit. Consolidated gross profit for the second quarter 2026 increased by 71%. to approximately $220 million. Similar to our prior quarterly results, reported gross profit includes stock-based and other compensation expense related to legacy profit interest units, where the payment of which is entirely borne by entities outside of Legions Corp., essentially the legacy pre-IPO shareholders. As a reminder, the settlement of legacy profit interest expense does not impact Legions Corp. either in the form of cash outlay or the issuance of additional common shares. Because these profit interest units are marked to market, any significant change to our share price will have a material impact on this expense, as it did in the second quarter. Excluding the impact of profit interest and related expense, adjusted gross profit on a consolidated basis totals approximately $234 million, and adjusted gross margin was 18.5% for the second quarter 2026, compared to approximately 130 million and 21.8% in the second quarter 2025. The decrease in adjusted gross margin was primarily driven by the combined impact of a shift in revenue mix to our installation and maintenance segment, reflecting the addition of Bowers and the segment's higher growth rate. as well as somewhat lower adjusted gross margin within the engineering and consulting segment. Looking into margins at the segment level, second quarter 2026 engineering and consulting adjusted gross margin was 31.1% down from 33.2% in the second quarter 2025. The adjusted gross margin decline largely reflects a revenue mix shift toward the program and project management service line, which accounted for 51% of segment revenue compared to 46% in the year-ago quarter. The installation and maintenance segment generated an adjusted gross profit margin of 16.1%, essentially in line with 16.2% reported in the year-ago quarter. As you would expect, there are a lot of moving parts that take us to that flat level year over year in the I&M segment. But to name a few, we saw a mixed shift toward the installation and fabrication service line at the expense of the higher margin maintenance and service line, but our overall mix of fabrication only work within the installation and fabrication service line increased year over year. Turning to SG&A, this expense includes approximately $59 million of stock-based and non-cash compensation expense, the vast majority of which, almost $54 million, was related to the legacy profit interest that is paid for by entities outside of Allegiance Corp. Excluding the impact of stock-based compensation expense, as well as approximately $2 million of acquisition and strategic initiative expenses, Our adjusted SG&A expense was $87 million, up from $62 million in the year-ago quarter. This increase was primarily driven by the addition of Bowers and higher general headcount to support our strong growth. More importantly, though, adjusted SG&A as a percentage of revenue improved significantly to 6.9%, down from 10.3% in the year-ago quarter as we benefit from greater economies of scale. All in all, we generated adjusted EBITDA of $155 million in the second quarter of 2026, an increase of 114% from second quarter 2025 levels. Adjusted EBITDA margin for the second quarter of 2026 improved by almost 20 basis points to 12.2% when compared to the year ago quarter. However, given the sequential comparison to first quarter 2026 adjusted EBITDA margins includes Bowers, we believe this is probably a more relevant comparison and yields an almost 90 basis point improvement. Depreciation and amortization totaled $44 million in the second quarter of 2026, up from $29 million in the year-ago quarter, with the increase largely due to the incremental depreciation and amortization that stem from the Bowers acquisition. Interest expense net of income was $15 million for the second quarter of 2026 and declined by almost $15 million from a year ago, primarily due to lower average debt balance and average interest rates than the year ago period. Turning to income tax, though we reported a pre-tax loss for the second quarter of 2026, we recorded income tax expense of $11 million due to the non-deductible nature of various items, primarily the legacy profit interest expense. As a result, on a reported basis, the effective tax rate for the quarter isn't all that meaningful. This dynamic is expected to continue through 2026 and into 2027 to some degree. Excluding the impact of these material non-recurring and non-cash items, The normalized effective tax rate would be closer to the high 20 to low 30% range, which we would expect to gravitate towards over time. Regarding cash taxes, our current estimate for 2026 is in the mid $50 million range. This is an increase from our prior estimate based on our revised profit outlook and states where our revised profit outlook originates from. Aside from our cash tax payments, we continue to expect to make a TRA payment of around $8-9 million related to our 2025 operating activity, likely in early 2027. Our TRA payment related to estimated 2026 activity is expected to total between $25 and the low $30 million range, and this payment is likely to occur in early 2028. To the extent we have additional share exchanges, this could slightly reduce our cash tax payments while increasing our TRA payments by 85% of the reduction in cash tax. So the net difference for allegiance is a 15% reduction in cash outflow. Now switching gears to backlog. We ended June with consolidated backlog and awards of $5.7 billion, up 105% from year-ago levels. compared to the first quarter of 2026, backlog in awards grew by approximately 289 million, translating to a book-to-bill for the second quarter of 1.2 times. Considering that our bookings tend to fluctuate due to the growing size of our project awards, viewing book-to-bill over a longer time horizon is also important. To that end, our last 12 months book-to-bill ratio was 1.4 times. In either case, these are fairly solid ratios, especially when taking into account our particularly strong quarterly revenue realization. In terms of our organic growth and backlog in awards, the data center and technology end market remains the primary driver. However, we are seeing healthy growth in state and local government, education, and manufacturing clients. Now turning to our guidance. We are establishing third quarter 2026 guidance for consolidated revenue of between $1.225 and $1.275 billion and adjusted EBITDA of between $150 and $160 million. For full year 2026, we're increasing our revenue guidance to a range of $4.7 to $4.8 billion. At the midpoint, This is increased by 13% from our previous guidance range of $4.1 to $4.3 billion that we presented during our first quarter report in mid-May. We're also raising our full year 2026 EBITDA guidance range by about 20% from prior guidance to $565 to $585 million, up from $470 to $490 million, again just three months ago. While part of our full year guidance increase is to account for our second quarter outperformance relative to guidance, it's more of a reflection on our growing backlog, current expectations on project timing, and a continuation of the strong execution that we've experienced in recent quarters. Now just a few additional housekeeping items to support your modeling efforts. Interest expense net of interest income for the second half of the year is expected to average approximately 15 million per quarter. Depreciation and amortization for the third quarter is expected to be similar to second quarter levels of 44 million. In terms of capital spending for the second half of 2026, we currently expect to spend between 40 and 45 million. This represents an increase to our prior full year guidance by 15 to 20 million, largely reflecting additional spending related to incremental fabrication capacity expansion that Jeff discussed earlier to outfit the new space, including cranes and advanced tooling, as well as additional spend on existing facilities. Our current capital spending forecast remains within 2% of expected revenue for the year, consistent with our historical spending levels for growth and maintenance capex. Now turning to our balance sheet, liquidity, and leverage. We ended the second quarter with $292 million of cash, up from $245 million at the end of the first quarter. Total liquidity was $461 million at quarter end, compared to $414 million at the end of the first quarter. Total debt at the end of June was slightly over a billion dollars, approximately flat from the end of the first quarter. Based on pro forma last 12-month EBITDA, which would include pro forma EBITDA from Bowers during the second half of 2025, our pro forma net leverage ratio is now 1.5 times, which is about half the level that we were after our IPO last September. During the quarter, we further lowered our debt costs with the repricing of our term loan. That repricing lowered our interest costs by 25 basis points at the outset. In early June, we received a credit rating upgrade from Standard & Poor's from B-plus to BB-minus, as well as from Moody's from B-1 to BA-3. With our credit rating upgrade, the loan pricing will step down by an additional 25 basis points to SOFR plus 175. That concludes my remarks, and now I'll turn the call back to Jeff.
Jeff Sprau
Chief Executive Officer
Thanks, Stephen. In closing, and before we get to the Q&A, I want to thank our entire team at Legions. Your commitment to safely serving our customers every single day makes it possible to deliver the incredible results that we are reporting today. Operationally, we continue to experience very robust organic growth across our diverse end markets and service lines, backlog continues to grow to record levels, and we are leveraging our growing scale and national footprint to deliver higher EBITDA margins. We expect these trends to continue and I'm really excited for what's next. With that, we'll now open the call up to your questions. Operator?

As a reminder, to ask a question, please press star 11 on your telephone and wait for your name to be announced. To withdraw your question, please press star 11 again. In the interest of time, we ask that you please limit yourself to one question and one follow-up. Please stand by while we compile the Q&A roster. Our first question comes from Adam Bubes with Goldman Sachs. Your line is open.
Adam Bubes
Analyst, Goldman Sachs
Hi, good morning. Morning. Morning. Nice to see the sequential bookings acceleration in the quarter, I think to about 1.5 billion in bookings. Can you just give us a sense of the size of the largest projects you're putting in backlog this quarter and make up of data center customers, whether hyperscalers or co-locators? And how are you thinking about the bookings trajectory in the balance of the year?
Steve Hansen
Chief Operating Officer
Yeah, we've had some really strong bookings in the data center, specifically in some TFO projects, which follow after base builds. They're ranging in anywhere from the $175 million range to between $200 million range there, as well as in our off-site manufacturing, third-party manufacturing. We've had some solid bookings there as well. and the trend, our pipeline that we don't report on is strong now and we feel like that trend will continue to be positive going forward.
Adam Bubes
Analyst, Goldman Sachs
And then can you just update us on a high-level breakdown on your key data center regions today and to what extent are your crews traveling and do you expect travel to increase as data center developments shift towards more rural markets?
Steve Hansen
Chief Operating Officer
Yeah, today Boots on the Ground, California, Phoenix, and the DMV are three major locations that we are performing installation work. Our fabrication is shipping all around the country from Salt Lake City to Georgia to Charlotte, North Carolina. So we are covering a large part of the country where we aren't located and have resources to do installation.
Jeff Sprau
Chief Executive Officer
Adam, this is Jeff. We've also, over the last several quarters, begun to travel into Texas via our adjacent business in New Mexico and are serving a handful of customers in that region as well.
Daniel
Conference Operator
Great. Thanks so much.
Jeff Sprau
Chief Executive Officer
Thanks, Adam.
Daniel
Conference Operator
Thank you. Our next question comes from Julian DeMullen-Smith with Jefferies. Your line is open.
Julian DeMullen-Smith
Analyst, Jefferies
Yeah, kudos. I've got to echo that last comment. Nice acceleration all around here. Jeff and team, look, if I can ask, just to lead off of this, bookings trend, how do you think about 27? You've obviously started, continued this year fabulously, put up even better results. It looks like the order book is accelerating here quarter over quarter. I just want to get a little bit of your commentary. You said it even at the end in your concluding comments that you're seeing an acceleration here. How is this portend into the next year? I just want to make sure I'm hearing you very clearly because obviously the near-term results are translating very squarely. I just want to hear how it extends here and sort of the duration, maybe if I were to zero in on one aspect of this. Can you compound off these elevated levels in the same confidence?
Jeff Sprau
Chief Executive Officer
Yeah, you know, it's really, I use the word momentum. The momentum continues to increase, Julian, and it's remarkable, and I think it's a function of Of course, amazing demand drivers. It's also a function of the fact that these projects are getting bigger. And as you are well aware, only certain companies are positioned to accommodate those larger projects. You need to have lots of employees. You need to have lots of square footage. And most importantly, you have to have the technical expertise and the relationships to be able to capitalize. and so we're just seeing it continuing to go up and up and to the right and I think the fact that we're not a one-trick pony in terms of just doing one service line, we do all service lines and we do it for many, many customers and so when you have that sort of, I guess, diversity of capability and diversity of customer and you have an amazing market backdrop That turns into momentum, and that's what we're seeing. And I don't see if you have anything to add.
Steve Hansen
Chief Operating Officer
Well said. I think the diversity in our end markets helps to continue that growth as well. And we're seeing, you know, we're just starting to see, Jeff mentioned it, the manufacturing end market and the reshoring that's happening gives us nothing but positive outlook.
Julian DeMullen-Smith
Analyst, Jefferies
Excellent. If I can zero in a little bit more on this. I mean, if you can speak a little bit more specifically, the working capital needs. as you think about like that as maybe an offset here just as the business accelerates and then related modular capacity expansion, you know, how large does your capacity need to be to adequately serve, right? Just if you can kind of speak into like how you accommodate this accelerating outlook as well in terms of the different pieces of this.
Stephen Butz
Chief Financial Officer
Yeah, Julian, good question. On working capital, as you'll probably recall, At the time we went public, we said that we could drive some improvements in working capital management, and I think you saw that the first few quarters out of the box where we even generated cash from working capital despite really strong revenue growth. We're probably now much closer to what I'd call normalized levels. This quarter it was a modest use of cash. I'd expect with revenue growth that to continue to be the case generally. It's always hard to call quarter to quarter because of the lumpiness of a balance sheet type metric like that, but I think that most of the improvements have already been driven through. That said, where we're working on customized fabrication modules, we tend to generate higher levels of prepayment than we do for our other services, so to the extent that continues to increase in our mix, that could be a positive.
Steve Hansen
Chief Operating Officer
And then from a fabrication square footage, Julian, we're sitting at 1.5 million square feet today. We have capacity for growth with that number now, and we can pull several levers within that footprint. We can add multiple shifts, more days on manpower load. but we will continue to grow. We look to add about another 100,000 square feet here in the coming weeks to that number and we'll monitor our incoming requests and backlog and size appropriately for work to come.
Julian DeMullen-Smith
Analyst, Jefferies
Awesome, guys. Nicely done. Yeah, kudos.
Steve Hansen
Chief Operating Officer
Thank you. Thank you.
Daniel
Conference Operator
Thank you. Our next question comes from Chad Dillard with Bernstein. Your line is open.
Chad Dillard
Analyst, Bernstein
Hey, good morning, guys. Good morning. Hey, good morning. I was hoping you could talk about your gross margins and backlog. What are they today? And can you bridge it to the gross margins that you have in your current P&L?
Stephen Butz
Chief Financial Officer
Yeah, our gross margins and backlog are generally similar, you know, to what our recent realizations are. You know, we haven't seen a dramatic change in pricing across the service lines versus, say, what we would have reported this quarter or even last, if that answers your question. Of course, there's always changes in mix, like what's in the backlog, but for the underlying services and service lines, similar levels of margin.
Chad Dillard
Analyst, Bernstein
Okay, yeah, that's helpful. And so as you look forward over the next couple of years, what share of your revenues do you think will be on like the modular and prefab side? and how do you put that in the context of your margin potential for just a broader business?
Stephen Butz
Chief Financial Officer
Yeah, great question. You know, we did see, as you recall, you know, really a ramp in our mix of FAB only type work, particularly in the second and third, fourth quarter of 2025. It's been at a relatively similar percentage the last three quarters when we think about our overall I&M revenue. It's been in the low 20% range the last three quarters now. And while we're experiencing really nice growth in that fab-only work, we're also winning large installation jobs. So both have been growing at a pretty similar rate. I'll hand it to Jeff or Steve in terms of the outlook for both of those.
Steve Hansen
Chief Operating Officer
From a manufacturing, third-party manufacturing, solid outlook, lots of inbound stuff, as we continue to see large projects built in more rural areas where there's just not a lot of resources there, we expect to see that continue. And to Stephen's point, the large installation projects that are inbound and continuing to get booked and run into our pipeline. You just see a solid outlook there.
Daniel
Conference Operator
Thank you. Our next question comes from Brian Brophy with Stifel. Your line is open.
Brian Brophy
Analyst, Stifel
Yeah, thanks. Good morning, everybody. Thanks for taking the question. Just continuing the conversation on some of the regional areas where you have data center exposure. Are you experiencing any notable difference in demand trends by region and particularly curious on DMV relative to other areas? Thanks.
Jeff Sprau
Chief Executive Officer
Yeah, I'll start, Brian, and I'll hand it over to Steve. You know, I think any changes that we've seen probably happened a couple of quarters ago when we started to see data centers get placed in more rural parts of the country, you know, call it middle America. which really changed the ship-to address on our fabrication work. And so now we are shipping to the Iowas of the world and the North Carolinas of the world and the Ohios of the world. That we obviously didn't see a couple of years ago. And so I think that's a notable difference. Now within sort of the primary markets, they are still the primary markets. The DMV is still data center alley. You know, Arizona and I'd say the broader southwest is still humongous. And obviously over the last probably 12 plus months, Texas is sort of broken into the top three.
Steve Hansen
Chief Operating Officer
Yeah, well said. And, you know, to Jeff's point, DMV continues to be strong. The Phoenix market and that Texas market that we have moved into and are shipping our manufactured product into Texas has been a strong growth pattern for us.
Brian Brophy
Analyst, Stifel
Appreciate it. That's very helpful. And then just maybe touching on the demand environment you're seeing on the semi-fab side, did you book anything notable in the quarter? And just general thoughts on the outlook there. Thanks.
Steve Hansen
Chief Operating Officer
Yeah, semiconductor still is ramping and getting stronger. We're seeing some incoming demand for OSM manufactured product for our semiconductor clients. We did grow our revenue in that end market as well in the quarter, and we are booking projects to continue that growth. Appreciate it.
Daniel
Conference Operator
Thank you. Our next question comes from Joseph Osho of Guggenheim Partners. Your line is open.
Joseph Osho
Analyst, Guggenheim Partners
Oh, hi. Thanks for taking my question. I was going to ask about semiconductors as well. I want to drill down on that a bit. If you look at Intel and TSMC down in Arizona and Micron up in New York, I mean, the numbers are pretty substantial with perhaps the four spaces is not quite the same. So I guess I'm curious, looking a few years out, can we imagine this segment may be becoming as large few as data centers, or am I being overly optimistic there? And then I have a follow-up.
Stephen Butz
Chief Financial Officer
Yeah, and Steve alluded to the fact that we did have nice revenue growth in semiconductors, you know, the contribution this quarter. I mean, it was stellar, over 50% growth. That said, that of course even pales to what we're seeing in the data center space.
Steve Hansen
Chief Operating Officer
Over time, though, I mean, the outlook is certainly good for semiconductors, but tough to... Yeah, I would say, and you hit on some of the key players that are growing and building out right now, and we will target them as Intel is one of our main clients in the Bay Area and other places. The TMC Phoenix market is super competitive in that region right there for the...
Jeff Sprau
Chief Executive Officer
The characteristics required for success in the semiconductor and the memory space are the same characteristics you need for success in data centers. They're complex systems. They're really, really big. They're custom, but they're high volume. and you have to be in that space. And we grew up in the semiconductor space. We grew up in the biotech space and we grew up in the data center space. So we love to see those announcements because that's going to fit right into our wheelhouse.
Joseph Osho
Analyst, Guggenheim Partners
Excellent. Thanks. And then just as a follow-up, we're starting to see some conversation following the 232 announcement ruling on larger scale investments in stale wafer and ingot capacity onshore in the US. I mean, notably that Tesla announcement the other day. I'm curious, is that a market that is of interest to you all? Thank you.
Jeff Sprau
Chief Executive Officer
You know, I'd say, Joe, that's, you know, certainly we're interested in our large clients and in what drives their demand. But I wouldn't say there's an outsized reliance upon or attractiveness to that sort of, I guess, evolution or volatility, for lack of a better term.
Daniel

Thank you. Our next question comes from Sabahat Khan with RBC Capital Markets. Your line is open.
Sabahat Khan
Analyst, RBC Capital Markets
Great. Thanks and good morning. I just wanted to talk a little bit about the sort of the non-semis, non-data center manufacturing side that you called up, more on the industrial side. Can you maybe just talk about some of the silos where you are seeing some of that reshoring activity? There's some folks out there saying they're not really seeing it in their business lines. Maybe if you can talk about which end markets you're seeing that in, you know, kind of the opportunity set. Are you doing some of the same type of work? You're providing some of the technology customers. Just a little bit more color on that opportunity. Thanks.
Steve Hansen
Chief Operating Officer
Yeah. So, I mean, we're, you know, reshoring I think is still kind of in early stages and we expect to see that grow over coming years. Currently, places like Tesla, SpaceX for us are great clients and we're seeing growth with them. and you know they're going to continue to build and inbound we've got a great engineering relationship with them as well as the installation so from both sides of our business will benefit from that.
Jeff Sprau
Chief Executive Officer
Yeah and you know it's interesting from a terminology perspective obviously GLP-1 drugs on the pharma side are huge. We have some great clients that we're helping them out in that regard. Now is that reshoring or onshoring or just starting from scratch I'm not sure. But again, those same characteristics, highly complex. You need engineering chops to be able to pull it off. You need the relationships. You need to have a resume. You've got to prove that you can do it. And so we, as Steve mentioned, in this baseball season, feel early innings on the reshoring perspective from our view.
Sabahat Khan
Analyst, RBC Capital Markets
Great. And then just in terms of my follow-up, it looks like sort of the $5.67 billion number here is about 60% of the data center technology space. You know, a round number is almost double the mix of last year. Do you have sort of a threshold in mind for the right mix of this business or look, the opportunities there, you'll capitalize on it and go from there? Just trying to Think about how you think about your go-to-market strategy. Are you still actively pursuing these customers? And if the mix gets larger, that's fine. Just how do you think about the mix of end markets across your business? Thanks.
Jeff Sprau
Chief Executive Officer
Yeah, I'll start and then I'll hand it over to Stephen. We've always wanted this growth to be an and versus an or. And I mean by that, we want to be able to satisfy demand from our customers, but not at the exclusion of our amazing customers in these other markets. And so we want it to be additive. Now, in a perfect world, I think it'd be nice and balanced, but so long as we are keeping our customers happy and we're not missing out or turning down opportunities in other markets that maybe are just sort of clicking along at high single digits, we really want it to be both. And to me, if data centers are 60% or 65% or 55% or 70%, doesn't matter so long as that we feel good about handling all of the opportunities. Now, if we have to start making decisions, then that's a different story, but I hope we never get to that position.
Stephen Butz
Chief Financial Officer
I don't know, Stephen, if you... Yeah, great point, Jeff. We don't want to turn away business from any of our good clients, no matter the end market, and so that's going to change our mix over time. The other area where we can change our mix over time is through M&A. Now, as you know are focused on high-end contractors, and of course on the engineering side as well, but those that focus on mission-critical facilities. So many of those are also going to have some data center exposure, but there certainly may be opportunities to add to our mix with other high-quality businesses that maybe are a little bit more skewed towards some of our other mission-critical end markets. That's something that we'll continue to evaluate over time.
Sabahat Khan

Thank you. Our next question comes from Michael Dudoff with Vertical Research Partners. Your line is open.
Michael Dudoff
Analyst, Vertical Research Partners
Yes, good morning, gentlemen. Good morning. Jeff, I get your sense of your customers across the board seem to be quite active. How are you looking at allocating capacity, time, your current labor force? how does that look relative to what you have to execute out of your backlog the next three to five quarters and are your clients looking to secure your services a much greater time into the future trying to secure opportunities where maybe it's even a couple years away before they're going to need what you guys do?
Jeff Sprau
Chief Executive Officer
Yeah, great question Michael and I'll start and then I'll hand it over to Steve and you called it the two levers that we look at After we get inbound demand, which thankfully has continued to be up and to the right, is do we have the labor to accommodate it both on the engineering side and the implementation or the boots on the ground side? And number two, do we have the right square footage? on the fab side. And those obviously work together. The more that we can do in the factory, all things being equal, you can do factory work with fewer people. And so it reduces the, I guess, pressure from a labor perspective. That said, and Steve, correct me if I'm wrong, we are not seeing labor constraints to the extent that we would have to either push out a project or anything like that. The fabrication square footage is an interesting capacity challenge and I'll hand it to Steve to walk through how we think through that.
Steve Hansen
Chief Operating Officer
Yeah, you're right, Jeff. Though there is tight labor around the country, we've been very successful at recruiting and bringing in people. As we build out that capacity and improve our fabrication floor prints, we're doing it with the latest in technologies and automation and skilled labor wants to come work on that stuff, right? So we've been able to track the labor we need. We haven't run into labor shortages. We're always mindful of it and looking and planning ahead. And then from a capacity standpoint on our manufacturing, and we talk a lot about our OSM third party manufacturing, even our installation and everything, we have a high priority on prefabrication, right? Take as much as we can out of the field, put it into our shops where we're much more efficient, you need less head count, it's safer, there's a ton of positives to it. And we can adjust by running multiple shifts. Today we run two shifts in a lot of our facilities and our second shifts are just light shifts to keep things moving for the next day. We can ramp those up and create capacity within our existing footprint to equal demand.
Jeff Sprau
Chief Executive Officer
You know, and the thing that probably is underappreciated, we really benefit from being a unionized it's a national labor force for us that we can pull from and people can travel on a moment's notice and what's beautiful about that, there's several great things about that, one of which is you know exactly you're getting a trained, safe, certified employee and you're pulling from all parts of the country and so if there's a soft part in one area of the country, we get travelers that come and they go to where the work is and certainly one of the ways that you can become a sort of preferred employer is when you have a huge backlog and when you have amazing customers and you have challenging technologies and cutting edge technologies and you're safe. Those are the criteria that folks think about when they decide if they want to go work on a job in say Texas or say Idaho for instance.
Michael Dudoff
Analyst, Vertical Research Partners
And just to follow up, what about on the client side, are they looking to lock you in longer into the future or how are those discussions, how are you allocating those resources to some of your, you know, try to keep it balanced as you mentioned in the response to a prior question of, you know, throughout all your customers in the markets?
Steve Hansen
Chief Operating Officer
No, it's a great question and, you know, we are having those conversations every day with our clients and we are seeing our backlog stretch into further out periods than we had historically. because they're aware too, right, that they need the resources to get their builds completed. So, yes, we are seeing an incoming demand for what does it look like, you know, 27 and beyond. So it continues to be a positive.
Jeff Sprau
Chief Executive Officer
Yeah, and I don't have data to support it, but generally speaking, you know it's driving ideally earlier decision-making and you know we're very we're a humble company and we basically tell our clients that we need to know because we need to lock in on whether it's designs or headcount or fabrication square footage and I think they realize that and so the earlier that we get engaged and start having those discussions the better that's I think one of the benefits of the fact that we have engineering as well as installation it's earlier client involvement and in mostly any industry the earlier you're talking to a customer the better and the more you understand the customer you understand their decision-making process you understand the competition you understand their pain points all that stuff earlier they're better for us and I think people are realizing and again I don't know that I have any anything other than anecdotes that that you know Since this is such a huge ramp, the earlier we talk, the better.
Michael Dudoff
Analyst, Vertical Research Partners
Very helpful. Thanks, guys.
Daniel
Conference Operator
Thank you. Our next question comes from Oliver Davies with Rothschild and Co. Redburn. Your line is open.
Oliver Davies
Analyst, Rothschild & Co Redburn
Good morning, guys. Just two for me. I mean, firstly, could you just provide a bit of color on the margin difference between installation and third-party fabrication sales? and then secondly I guess you mentioned larger awards but speed to market is key so just any comments on the sort of conversion length of the backlog whether that's materially changed over the past six months or so. Thanks.
Stephen Butz
Chief Financial Officer
Yeah on the first one of course you know we don't we don't disclose the differences of the sub-levels of services versus you know how we disaggregate revenue but but I think I think what what we can happy to say is that When we're completing a full installation job, those margins, the revenue opportunity is much, much bigger than just a FAB only. There's flow through equipment, sometimes subcontractor costs, and so our margins are lower than when we're essentially manufacturing customized products. We do get a nicely higher margin on those. And so that should be a positive to our margins over time as we continue to do more FAB only work. But then I'll hand it to Steve for the second half.
Steve Hansen
Chief Operating Officer
Yeah, on the acceleration of schedules and on these projects, we are seeing acceleration on every end market we're in. There is a race to the finish line, especially in the data center world. and the semiconductor world that we're in, they want to ramp their projects and get them done. They're all competing with their peers just like we are. And so we are seeing those pull in. We're seeing shorter time frames. And again, our ability to leverage the 1.5 million square feet of fabrication capacity allows us to work with our clients and pull those projects in on a timely manner for them.
Son Vann
Vice President of Investor Relations
Great, thank you.
Steve Hansen
Chief Operating Officer
Thank you.

Thank you. Our next question comes from Chris Sung with Wolf Research. Your line is open.
Chris Sung
Analyst, Wolfe Research
Hey, good morning. Just one question for me. Steven, you mentioned project timing continues to run execution as drivers of the race, and I think Steve just talked about the acceleration of projects ramping faster. Can you just separate how much of the increase in guidance this year is revenue being pulled for versus incremental work that wasn't necessarily contemplated last quarter. Thanks.
Stephen Butz
Chief Financial Officer
Yeah, it's hard to provide a split on that. I think it's a combination. I think the pull forward, we certainly benefited from that in a sense in the second quarter, you know, versus our guidance. When I said pull forward, we were just executing on some of the, particularly the FAB projects quicker than originally anticipated. So there's some of that in our guidance, but also, you know, just We've got a strong backlog coverage on our second half results, and so that was part of our overall guidance raise as well.
Daniel
Conference Operator
Okay, thanks. Thank you. And our final question comes from Derek Soderberg with Cantor Fitzgerald. Your line is open.
Michael Dudoff
Analyst, Vertical Research Partners
yeah hey guys um just wanted to uh dig into the engineering and consulting segment i think gross margins there were down a little bit i was wondering if that was more labor costs or you know project mix and then just as a follow-up on that i'm curious if the E&C margins are different for work that's sort of attached to larger projects versus smaller projects thanks yeah i'll take the first first part of that um
Stephen Butz
Chief Financial Officer
You know, our margins, again, the difference in the year-over-year margin was driven by a mix. We had a larger contribution from our program and project management, which includes performance contracting, than our higher margin engineering and design service line. And that's really what accounted for the difference year-over-year. And then just more broadly, as I look at the thing about the margins in that segment, We had one quarter that was an outlier quarter where we had really high margins over the past two years. But otherwise, over the last eight quarters, we've generally been in the 31% to 33% range and the difference driven by mixed shifts. The one area, again, that we talked about, sustainability consulting, where we've seen a little bit of degradation, as we discussed, That's sort of plus or minus 10% of that overall engineering and design service line, so very small piece. Overall, though, the margins for the underlying services have been consistent, essentially, within that period and other than that, and the changes have been driven by makeshifts.
Jeff Sprau
Chief Executive Officer
Yeah, and I would just piggyback on that. We haven't seen, I don't think, a material difference in engineering fees by vertical market. whether the engineering fee for a data center versus a hospital versus a university versus a K-12. I think they're similar. I'm sure they're not identical, but nothing that would sort of move the needle from our perspective.
Sabahat Khan
Analyst, RBC Capital Markets
