Ladies and gentlemen, thank you for standing by. My name is Krista, and I will be your conference operator today. At this time, I would like to welcome you to the Jacobs Solutions fiscal first-quarter 2026 earning conference call and webcast. (Operator Instructions) Thank you.
I would now like to turn the call over to Bert Subin, Vice President, Investor Relations. Bert, you may begin.
Bert Subin - Senior Vice President - Investor Relations
Thank you, Krista, and welcome, everyone. Following market close, we issued our earnings announcement, filed our Form 10-Q, and we have posted a slide presentation on our website, which we will reference during the call. I would like to refer you to slide 2 of the presentation for information about forward-looking statements, non-GAAP financial measures, and operating metrics. Now let us turn to the agenda on slide 3.
Speaking on today's call will be Jacobs Chair and CEO, Bob Pragada; and CFO, Venk Nathamuni. Bob will begin by providing comments on the business as well as highlights from our first-quarter results and a recap of notable awards. Venk will then provide a detailed review of our financial performance including commentary on end market trends, cash flow, and balance sheet data. Finally, Bob will provide closing remarks, and then we will open up the call for questions.
With that, I will turn it over to our Chair and CEO, Bob Pragada.
Robert Pragada - Chief Executive Officer, Director
Good afternoon, everyone, and thank you for joining us to discuss our first-quarter 2026 business performance. We delivered very strong results for Q1, exceeding our expectations across all key metrics and made incremental progress toward achieving our FY29 target. I will quickly highlight a few key takeaways
First, adjusted EPS grew 15% to $1.53 supported by robust 8% net revenue growth and solid underlying margin performance. Second, our backlog grew 21% to over $26 billion setting a new record with our trailing 12-month book to bill rising to 1.4 times. And third, we announced an agreement with the shareholders of PA Consulting to acquire the remaining stake in the company. We see PA's core competencies in digital consulting, innovation, and AI advisory as a force multiplier for Jacobs and a key accelerant in our strategy to redefine the asset life cycle.
In summary, we are exiting Q1 with momentum, and the strong start to the year gives us confidence to increase our FY26 outlook for net revenue, adjusted EPS, and free cash flow margin, which Venk will go through in detail shortly.
Turning to slide 4, we provide a detailed overview of our quarterly results. We are very pleased with Q1 results as a strong operating performance paired with our lower share count drove the fourth straight quarter of double-digit growth in adjusted EPS. During Q1, we also reported a substantial increase in our quarterly book to bill to 2.0 times positioning us well for the rest of FY26 and beyond.
Turning to slide 5, I would like to highlight a few notable I&AF project awards for the first quarter. Q1 included several marquee wins that reflect the breadth of our capabilities and the strength of demand across our end market. Starting with water and environmental, we were selected to lead the engineering design for the Bolivar Roads Gate System along the Texas Gulf Coast. Spanning the narrow strait connecting the Gulf to Galveston Bay, this project is expected to be amongst the largest storm surge barriers in the world
Once completed, it will help protect more than 6 million people while safeguarding businesses and maintaining operations along the Houston Ship Channel, a critical energy corridor. This major program underscores our leadership in delivering complex and high-impact water infrastructure focused on long-term resilience.
In life sciences and advanced manufacturing, we were selected to provide engineering, procurement, and program management services for Hut 8 Riverbend Data Center in Louisiana, a flagship AI and high-performance computing project. The facility is poised to be one of the largest of its kind in North America. The region's power dense utility infrastructure enables the speed, reliability, and flexibility required for next-generation AI workload. This project demonstrates how we are leveraging our deep domain expertise in data centers, power, water, and digital twin technology to deliver increasingly complex facilities.
In critical infrastructure, we continue to secure high-value, mission-critical programs that underscore the strength of our combined Jacobs and PA Consulting capabilities. Notably in the UK, the Health Security Agency selected PA supported by Jacobs to act as delivery partner in its Trust Program, an initiative focused on strengthening resilience and safeguarding critical health data and infrastructure. Through advisory, technical, and delivery support, we will help the agency meet data security and cyber requirements ensuring the systems that underpin public health and emergency response remain resilient and secure. This award reflects the growing demand for our integrated consulting and delivery approach and reinforces our role in supporting some of the UK government's most critical priorities.
Also within critical infrastructure, we were selected to lead program and construction management services for the $1.6 billion modernization of Cleveland Hopkins International Airport. The program will modernize aging infrastructure and improve accessibility and passenger flow at Ohio's busiest airport.
Jacobs is ranked as Engineering News-Record's number one firm in aviation, a sector where we continue to see significant growth in demand for terminal upgrades, master planning for new builds, digital implementation, and AI advisory.
In summary, we are deepening our relationships with key clients which is driving multifaceted multi-year program wins as demonstrated by our significant backlog growth in the quarter.
I will now turn the call over to Venk to review our financial results in further detail.
Venkatesh Nathamuni - Chief Financial Officer, Executive Vice President
Thank you, Bob, and good afternoon, everyone. I would like to echo Bob's earlier comments on our announcement to acquire the remaining stake in PA Consulting. Our partnership over the last five years has truly differentiated our approach to our clients business, and we look forward to accelerating the integration of our combined offering. A year ago at our Investor Day, we talked about the power of focus, and increasing our ownership in PA Consulting to 100% will support our goal to simplify our structure, execute on our strategy, and produce predictable high-quality earnings over the long term. Now please turn to slide number 6, where I will walk through our results for Q1.
In the first quarter, gross revenue increased 12% year over year and adjusted net revenue, which excludes pass-through revenue, grew by more than 8%. Q1 adjusted EBITDA was $303 million, growing more than 7% with our margin coming in at about 13.4%. We saw that last year during Q1, we absorbed less PTO than anticipated, resulting in a margin tailwind that did not recur this year. Overall, adjusted EPS rose 15% year-over-year, a great start to fiscal year '26.
Consolidated backlog was up 21% year-over-year to a record $26.3 billion with our trailing 12-month book to bill rising to 1.4 times. Book to bill was particularly strong in Q1 driven in part by several large awards in the life sciences and advanced manufacturing end market. We expect these awards to contribute positively to net revenue growth through fiscal year '26 and beyond, but do note that they carry higher-than-normal pass-through revenue. Importantly, gross profit in backlog, which would not be impacted by this pass-through dynamic, increased 15% year-over-year during Q1, highlighting the underlying strength of our sales performance.
Regarding our performance by end market and Infrastructure and Advanced Facilities, let us now turn to slide number 7. At a high level, all of our end markets performed well during the quarter with strong revenue growth in life sciences and advanced manufacturing and critical infrastructure within I&AF as well as PA Consulting. As a result, we finished above the high end of our Q1 forecast for enterprise net revenue growth.
Focusing in on life sciences and advanced manufacturing, net revenue grew 10% in Q1, a nice improvement from Q4 as programs in our advanced manufacturing vertical ramp up. As we have noted in past quarters, strong award activity in both the data center and semiconductor sectors is now helping drive higher growth. Additionally, we continue to see favorable trends in life sciences, and this combination positions us well for the remainder of the year. Our current expectation is that growth in this end market will lead I&AF in fiscal year '26 as programs ramp up during the second half of the year.
Shifting now to critical infrastructure, net revenue increased 8% over Q1 2025. Critical infrastructure is performing well across the board with robust growth in transportation particularly in rail and aviation, driving strong overall growth for the end market.
Net revenue growth in our water and environmental end market increased sequentially to 4% driven by high-single-digit growth in water and a modest easing of headwinds in environmental. We forecast year-on-year performance for environmental will improve as we move into the second half of the fiscal year. In summary, we performed well across our end markets during Q1, and we believe we are positioned nicely for the remainder of fiscal year '26 and beyond.
Now moving on to slide number 8, I will provide a brief overview of our segment financials. In Q1, I&AF operating profit increased modestly year on year with similar constant currency performance. PA Consulting operating profit increased 27% on 16% revenue growth at a strong operating margin of 24%. On a constant currency basis, operating profit grew 22%. PA continues to benefit from rising demand for digital consulting and advisory services in the public, national security, and energy sectors. As we look ahead, we expect PA's revenue growth to remain solid with fiscal-year '26 tracking in the high-single-digit range year on year.
Moving on to slide 9, we provide an overview of cash generation and our balance sheet. For Q1, free cash flow came in at $365 million supported by solid working capital performance as well as a favorable cash timing item at the end of the quarter that will reverse in Q2. Excluding this timing item, underlying free cash flow performance was still very strong and gives us confidence to raise our full-year free cash flow outlook, which I will discuss shortly.
Focusing in on capital returns, we increased our share repurchase quantum during Q1 to take advantage of the dislocation in our shares in the second half of the quarter. As a result, we are starting the year well on our way to returning at least 60% of our free cash flow to shareholders. Additionally, we announced last week that we will be raising our quarterly dividend from $0.32 to $0.36 a share, a 12.5% increase. We have now more than doubled our quarterly dividend per share since 2019.
Additionally, our net leverage ratio currently stands just below 0.8 times on LTM adjusted EBITDA, which is well below our 1.0 to 1.5 times target range. Our balance sheet strength has enabled us to increase share repurchases, raise our quarterly dividend, and enter into an agreement to purchase the remaining stake in PA Consulting. The acquisition of the remaining stake in PA will raise our net leverage to slightly above the high end of our 1.0 to 1.5 times target range upon closing, but we expect to return to the target range within a year.
Finally, please turn to slide number 10 for our updated fiscal year '26 outlook. We are increasing our forecast for adjusted net revenue growth, adjusted EPS growth, and free cash flow margin relative to our guidance from last quarter. We are increasing our fiscal-year '26 net revenue range to 6.5% to 10% year over year, adjusted EPS range to $6.95 to $7.30, and free cash flow margin range to 7% to 8.5%. Our expectation remains unchanged for an adjusted EBITDA margin range of 14.4% to 14.7%. Notably, our outlook for fiscal year '26 implies over 16% year-on-year growth in adjusted EPS at the midpoint.
We provide relevant assumptions on the right side of the page to help with your modeling. Please note that our guidance does not reflect the announced acquisition of the remaining stake in PA Consulting, and we plan to update our outlook once the deal closes likely with our Q2 results in May. Based on current assumptions, we expect the acquisition to be accretive to adjusted EPS in the first 12 months following closing. We anticipate the $16 million to $20 million in projected cost synergies will begin to phase in during fiscal-year '26 with revenue synergies providing incremental upside.
As it pertains to Q2, we expect our adjusted EBITDA margin to be in the range of 13.8% to 14% with year-over-year net revenue growth of approximately 6.5%. In summary, we are off to a great start in fiscal-year '26 and remain focused on strong execution, profitable growth, and continued capital returns.
With that, I will turn the call back over to Bob.
Robert Pragada - Chief Executive Officer, Director
Thank you, Venk. In closing, we're tracking very well to the start of the new fiscal year. We performed ahead of our expectations in Q1, enabling us to increase our full-year outlook across three key metrics after just one quarter. Our strong execution, secular growth tailwinds, and the announced acquisition of the remaining stake in PA Consulting position us extremely well to deliver on our FY29 targets.
Operator, we will not open the call for questions.

Sabahat Khan, RBC Capital Markets.
Sabahat Khan - Analyst
Maybe just a higher level question on the outlook here, and obviously, this last calendar quarter to end the year had some concerns about a government shutdown. It doesn't to have flowed into your numbers. Similarly obviously, some puts and takes on the macro. If you can just walk us through what's reflected in your guidance, what it would take to get you closer to the higher end of the top-line guide versus the lower end, and how you have baked in some of the potential green shoots and potential government-related consideration into this updated guidance to start off?
Robert Pragada - Chief Executive Officer, Director
Yeah, sure, Sabahat, just on your first one with regard to how we position ourselves within that revenue range that we talked. I would say that it would be the burn profile of the backlog. We had some really nice wins within our life sciences and advanced manufacturing group driven by data centers and chip manufacturing. Those tend to have pretty high velocity to them, and so if those continue to go at the pace that they are, that would be a driver.
And we are also seeing a nice pickup across the international business. Our international business grew over 9% this year, and that was pretty broad based in Europe, Middle East, as well as in APAC. And so I think that balance of our business and not feeling the effects of the government shutdown has given us confidence in the range that we put out there. But again, it would be the velocity of that private sector work that would get us to the higher range.
Sabahat Khan - Analyst
Great, and then just for my follow up. I think Venk's comment around the environmental services side of the business doing better in H2. That was a business that investors had some questions about last year just given some of the evolutions and the backdrop. Nice to hear that's trending in the right direction.
Can you maybe just talk about, is it a specific end market that is driving that or is it just maybe some catch up? What are the bigger picture demand drivers of the environmental services business because it has been a bit of a focus for investors?
Robert Pragada - Chief Executive Officer, Director
Yeah, Sabahat. I would segregate it into three buckets of how it affected us over the course of calendar '25, and now we're starting to see a bit of an inflection point in our pipeline that's why we are pointing to the second half as a recovery. The government component of that for us is very centric toward the United States Department of Defense, and now we are starting to see some larger programs specifically for the Navy and the Army Corps of Engineers come through with some optimism on where we position long-time clients of ours. And so that's kind of one piece. The second piece -- and that would -- had some of the indirect effects of DOGE if you think back to '25, so now we're seeing that flow through.
The second is around the -- the transfer around the disaster relief work from the federal government to state and local. That has taken a longer time to settle down, and so as that continues to play out, we are starting to see some early indications of that in our pipeline. And then the third is, we have seen the pick-up in this component is the private sector, and this is kind of the diversity of how we apply our environmental practitioners across our private sector in whether it be industrial or in life sciences and advanced manufacturing.
Those jobs have started to pick up. They are smaller in scale, so they are not having an effect right now, but as that continues to grow and we're seeing it again in our pipeline, that pipeline is up double digits, so that's where we're pointing the second half.

Michael Dudas, Vertical Research Partners.
Michael Dudas - Analyst
Very impressive certainly on book to bill (technical difficulty)
Operator
Pardon the interruption. Michael, we are having a hard time hearing you.
Michael Dudas - Analyst
Can you hear me now?
Robert Pragada - Chief Executive Officer, Director
Yeah, got you now, Mike.
Michael Dudas - Analyst
So Bob, very impressive on the book to bill backlog growth in Q1. Maybe you could share on the -- it looks like the projects are getting larger, a little longer for gestation but much more complex, and how that plays toward what your current pipeline looks, maybe that two-year pipeline look and the ability to gain more, I guess, life cycle revenues or business out of the bidding that you're working on with the negotiation with these larger projects with the clients that certainly we've been reading about in the press that seem to be accelerating their cap spend especially in your important private sector markets?
Robert Pragada - Chief Executive Officer, Director
I would say maybe one comment on the overall portfolio, and I will talk specifically about what we are seeing in the private sector accelerate at a faster pace. Overall, this has always been our strategy. We talked about it at Investor Day with regard to redefining the asset life cycle and continuing to work across that. That is happening on a broad base. I'd say that gestation period of the work probably is going faster within water, a little longer in transportation and energy and power, but we're moving at a pace.
Private sector is happening in real time and a lot of it is for just the demand cycle that is happening in those end markets whether it be data centers, chip manufacturing, and life sciences. So for us, that business is in growth mode. We are seeing the pipeline grow at some significant rates. I'd say that two-year pipeline that you're referencing, one year is greater than 50% if I were to have a composite rate and as you get past that period. In private sector, we don't really get past 18 months with any kind of high level of surety in pipeline, but that 12 to 18 months, definitely greater than 50% on a composite rate.
Michael Dudas - Analyst
I appreciate that. Excellent, Bob. And my follow up for Venk, with the very strong Q1 start of cash flow and the dynamics throughout the year. So given the financing that you are participating on PA and such, the 60% free cash of the company is still targeted towards again the share repurchase on a more rateable basis. You feel still comfortably to delever and add opportunistically when the market requires on your capital allocations in this year?
Venkatesh Nathamuni - Chief Financial Officer, Executive Vice President
Yeah, Mike. Thanks for the question, and as you pointed out, pretty strong start to the year in terms of free cash flow generation. And we feel pretty good about where we end the year, which is why we raised the guidance. So as it relates to our current position in terms of repurchases, obviously we increased our repurchases in Q1 to take advantage of the market dislocation as I mentioned in the script, but we also increased our dividends. So we feel very good about our commitment to returning 60%-plus of free cash flow to shareholders.
At the same time, with the solid balance sheet and the good cash flow that we are generating, we also want to quickly delever from the 1.0 to 1.5 times range when we do the PA financing. We have good line of sight to be able to get to that range within the first four quarters. So a solid cash position to start with, really good cash flow, and we have enough firepower to allocate our capital between repurchases as well as debt paid out.
Operator
Sangita Jain, KeyBanc Capital Markets.
Sangita Jain - Equity Analyst
If I can follow up on the cash flow question, Venk, you said the cash in the quarter was quite high but some of it may reverse in the second quarter. Could you elaborate on what that reversal relates to? And also, I was under the impression there were going to be some cash tax payments that you would have to take care of in the first half. Has the timing of that changed?
Venkatesh Nathamuni - Chief Financial Officer, Executive Vice President
As you pointed out, really good cash flow in the first fiscal quarter. I would say the vast majority of that strong cash flow was driven by really fantastic working capital performance across the entirety of our customer base, so that was number one. We also had a one-time impact from a customer in the data center space where we collect the revenue and the cash during a particular quarter, and then we pay the subcontractor in subsequent quarters. So that's what's going to drive the free cash flow performance in Q2, but we have very good visibility that in the first half, we will still be free cash flow positive.
And the tax payment, as you mentioned, is going to be a Q2 phenomenon, so that will impact Q2. But when you look at the first half and -- first couple of quarters in aggregate, we feel pretty good about our free cash flow being positive for the first six months of the year and obviously continued strength in Q3 and Q4 such that we are able to get to the 7% to 8.5% range.
Sangita Jain - Equity Analyst
And then just a follow up, can I ask about the Sizewell C contract that you press released a while back in the UK, and if you can elaborate on the size of that and if there is a chance that the scope on that may increase over time?
Robert Pragada - Chief Executive Officer, Director
It could. We are doing -- just to clarify on that, Sangita, we're performing the enabling works and the program management around the enabling works. And so that has continued through -- actually it started even before '25 -- '24, '25, and will continue into '26. There is opportunity for continued scope growth on that, and our relationship there with Sizewell C is strong, so we would anticipate so.
Operator
Steven Fisher, UBS.
Steven Fisher - Analyst
Just in light of the backlog growth, obviously we know from some of the press releases descriptions of what your scope is on some of these projects, but just curious what some of the pass-through things are that are going through there. And maybe if you can give us maybe a sense of maybe looking at the profit, increase in backlog might be more representative. I know you said 15% year over year, curious if you can give us some measure of that sequentially.
Robert Pragada - Chief Executive Officer, Director
Yeah, let me go -- I will go back to the sequential gross profit in backlog, but I would say, Steve, that the majority of the pass through is related to, as you know in the data center, tremendous amount of electrical equipment and equipment purchase that will be -- and it was announced on who is going to be providing that equipment in modular form. So the interconnects and how that equipment is arriving to site in modular form would all be around the envelope of a pass through.
We would do the design and not just that, but also the balance of plant to house as well as the interconnections of all the utilities. The trade contractors also end up making that pass through too. And traditionally, we put a fee on both of those. On the gross profit sequentially, growth, say it's high-single-digits sequentially quarter to quarter. Year on year, that 15% number is a strong number.
Steven Fisher - Analyst
Okay. Very helpful, Bob. And then just obviously last quarter in the last few months, there has been lots of discussion and follow ups about AI, and I am just curious if there has been any change to either what you have observed in your own business, anything that has developed or your own thinking or message that you would like to give on the AI outlook impact for the industry and the company?
Robert Pragada - Chief Executive Officer, Director
Yeah, absolutely, Steve, nothing has changed. We felt strongly about AI before the November event that happened, and we feel equally and more strong about AI moving forward. The main things we have been talking about not just in Q1 -- I'm sorry, for the Q4 call in Q1, and that we have been talking about since 2019, we are getting great data advantage in what we do.
Our datasets and our information continue to be strong, strong platforms for us to use for insights as well as build the models that we are building for our clients. It is helping. When I say it, digital enablement in AI with the scarcity of resources that we are continuing to face. We are growing headcount while we are using digital enablement to continue to grow at the same time as that scarcity.
And I would say, the biggest piece has really been around what is happening in the AI ecosystem from chip manufacturing to power and water requirements all the way to the data center. We are playing across that continuum and seeing that we will see it in the numbers, right, so kind of the ultimate test of the power of AI is coming through in our bottom-line results.
Operator
Adam Bubes, Goldman Sachs.
Adam Bubes - Analyst
Maybe just one follow-up on the AI point. So you've been talking about AI machine learning for a couple of years now. And so just wondering if you could expand on to what extent AI machine learning is impacting projects and productivity today? And just how those conversations with clients have gone in terms of your ability to capture value from either improved productivity or high-grading your offerings?
Robert Pragada - Chief Executive Officer, Director
Yeah. So a couple of things. One, as far as how we're talking to our clients about it and how we are driving it is a value differentiator for our clients. If you think about the speed right now that we are going at, especially not just in the private sector but also in the water market as well and transportation the schedules and the delivery model for these can't be done without the use of the AI platforms. And when I say AI Machine Learning, the automation of tasks that we put into play. So it is driving backlog growth through differentiation in our award rates and the bookings.
The other is that in the field, we're using some strong predictive analytics to platform called Acuity in order to really get out in front of field level issues that are coming up in real time. And that's been a real game changer for us. We've got acuity deployed across all of our end markets. in the field program management work that we do. And then the last thing, and we've talked about this several times, but we're seeing more -- we use Replica as our digital twinning.
But now digital twinning not just in the water sector, but now in the manufacturing sector and the data center sector is allowing for us to get to the data insights in the simulation technologies -- with the simulation technologies in a much faster rate in order to solve for some really, really complex issues that we're solving for our clients.
So overall, it's coming through. We've got a whole slew and suite of platforms that we're using.
Adam Bubes - Analyst
And then really strong PA consulting margin performance, I think, 24% this quarter. Any outsized benefit to call out there? Or what's the right way to think about sustainability of those margins in the balance of the year?
Robert Pragada - Chief Executive Officer, Director
Yeah, Adam, great question. So I would say, yes, as you point out, really strong performance. Most of it is driven by the fact that there's a solid top line beaten we had some operating leverage there as well. What we have stated all along is that we want to balance really high single-digits growth for PA with margins that are, as you know, already industry best. So a 22% margin is kind of the way we think about as a long-term model there, and we want to make sure that we have a good balance between high revenue growth and high industry-leading margins.
So the way to model PA margins going forward is about 22%. But clearly, we had a really strong performance there in the just concluded quarter.
Operator
Jamie Cook, Truist Securities.
Jamie Cook - Analyst
Congratulations on a nice quarter. I guess, sorry, Bob, another question on AI. Just as you sit here today, and think about AI and the opportunity for Jacobs, both on the revenue on the margin side. How do you balance the two? Do you know what I mean?
I mean over time, if you had to pick one versus the other, do you think there's an opportunity to grow the top line at a quicker rate and perhaps operating profit more so versus the margin? Just sort of how you're thinking about that balance as AI impacts your business model? I guess it's my first question, and then I'll ask another one after that.
Robert Pragada - Chief Executive Officer, Director
Okay. Great. Jamie, if the world was plentiful with qualified resources for all the work that's out there, from filling the denominator of the TAMs that we play in. I think that we would probably be making choices between top line and bottom line, we're not. We are in a resource constraint market that AI is enabling us to grow the top line while we're operating with -- in a resource-constrained environment and driving efficiencies and type of solutions that we're delivering to our clients.
So not a choice as well as not a pivot. We feel like we're well positioned to do both.
Jamie Cook - Analyst
Okay. And then I guess, Venk, just on the margin performance in I&AF in the back half of the year. Obviously, we're expecting some margin improvement to achieve besides PA Consulting strong margins to help get to your full year adjusted EBITDA margin forecast, just what's driving that? Is it more mix? Is it self-help?
Just trying to understand what's driving the margin improvement in I&AF in the back half of the year?
Venkatesh Nathamuni - Chief Financial Officer, Executive Vice President
Yes. Jamie, thanks for your question, and thanks for your comments as well about the quarter. I'd say lots of really positive trends for us from a margin perspective. Obviously, Q1, we came in at 13.4%. And Q2, we're guiding for a 50-basis point sequential improvement.
And then we see a linear progression in Q3 and Q4. So a few things that drive that margin expansion for us. Number one, continued operating leverage. So we're going to maintain the discipline in terms of ensuring that our OpEx grows at a slower pace than revenue growth. And then clearly, from the standpoint of some of the gross margin drivers that we talked about at Investor Day, with the way we expect our global delivery to step up, which is already happening, and we see more of that coming in Q2, Q3 and Q4.
And then also on the commercial model side, right? So with the extent -- to the extent that we are engaging more with some of the life sciences and advanced manufacturing clients, that also helps from the standpoint of driving those commercial models. So I would say it's not 1 thing. It's a combination of several things that we talked about at Investor Day, more of that coming to fruition in Q2, Q3 and Q4. and we feel really good about our margin performance for the full year.
Obviously, just for context, in fiscal '25, we grew our margins by 110 basis points, and we're guiding for a range of 50 to 80 basis points increase in fiscal '26.
Robert Pragada - Chief Executive Officer, Director
Maybe one add to that is that in the second half is really where we're starting to see the advanced facilities or some of these bookings that we have from a mix perspective. You have a contribution to that linear progression in our margins and confidence.
Operator
Andy Wittmann, Baird.
Andrew Wittmann - Analyst
I wanted to ask about this very good backlog. It's very exciting. Obviously, in some of these really marquee projects. Bob, I thought maybe given that there's a little bit more mix here to some of this EPCM scope, I want to ask about how you're managing the risk criteria here. Are these contracts -- are you basically able to offload any risk to these two the subcontractors that you are managing on this?
Or do you bear any? I'm just wondering because, obviously, some of these projects are pretty significant and percent changes on large numbers could actually kind of matter in the future. So maybe I'll let you address that, please?
Robert Pragada - Chief Executive Officer, Director
Yes, absolutely. So our risk profile, Andy, has not changed. And so the same EPCM delivery model that we've been very focused on for the balance of 20 years, in life sciences. We do a lot in the water sector as well. Those are the same risk profiles we're taking now.
And as you know, we've been pretty consistent on how we flow those to our supply chain. So the awards that we're getting right now, we have not inflected to a different risk profile. We're utilizing the same risk profile we have for the balance of the 20 years in those sectors.
Andrew Wittmann - Analyst
Okay. Great. And then I just wanted to get a clarification on PA and the capital deployment that went along with that as well. It's obviously a large capital deployment. So when I was looking at the press release, the EBITDA increase that you're getting from PA is because PA is already consolidated, the EBITDA that you're picking up is really only the reduction of the noncontrolling interest.
Obviously, noncontrolling interest is after tax. You'd have to gross that $52.3 million up to a larger number. But even when you do that, against the $1.6 billion capital outlay the math that I get here for the multiple is substantially larger than the 13 times.
And so I know there's some kind of different accounting -- GAAP accounting that's maybe around this. And I just thought for the benefit of everybody, you could address how that works and why it works out that way, please?
Venkatesh Nathamuni - Chief Financial Officer, Executive Vice President
Yes. Andy, thanks for the question. And I know that we -- obviously, you mentioned that in your report as well. So at a high level, as you rightly pointed out, there's a slight difference between the accounting and economic ownership. So just for everybody's benefit here, the economic ownership of 65% and the accounting ownership of 70%.
But there's obviously some dilution from what we call C shares, which are basically shares that the employees own. So to make a long story short, that's the delta. But in terms of the absolute valuation, as we mentioned in the press release, it's a 13 times multiple on EBITDA. And then if you take into account the synergies at the 12.3% multiple, so we feel really good about the valuation for this and the value creation. But happy to take additional questions and maybe Bert, you can add to it as well.
Bert Subin - Senior Vice President - Investor Relations
Yeah, sure. Maybe what is actually what's happening here is -- when you take the accounting ownership, which was 70% and you reduce it by the employee benefit for us, we get down to a 60% ownership. And so we acquired 40% of the stake, which we highlighted. On the NCI, what we did is we reduced EBITDA by an after-tax number. And so reduced EBITDA by a smaller amount.
So essentially, we'll be adding back that NCI component to our EBITDA going forward. I think the important takeaway that we -- Venk highlighted in his prepared remarks is we expect this to be accretive to earnings and we see a lot of opportunity from both the revenue and cost synergy with the combination of PA and Jacobs. So we can take some of the more specifics offline, what we talk later on.

So I wanted to spend some time on the project pipeline. I think you talked about it being up double digits. Could you break that down by the core end markets? And maybe you can comment about fixed versus reimbursable? And then finally, just on the global delivery model?
How much of that is deployed using that method versus what's in your revenue today?
Robert Pragada - Chief Executive Officer, Director
Yes. Maybe I'll simplify it, Chad. If you look at our three main verticals, water environmental up, the pipeline is up. And when I say double digits, very much double digits that are 25% and above. In life sciences and advanced manufacturing, double-digit pipeline growth, those are 50% and up.
And in our critical infrastructure, we're talking kind of high single digits and low-double-digit pipeline growth. That's not acutely focused on the US. That's a global number. And so the pipeline is strong, and that's a 12- to 18-month pipeline that we look at that -- then there's win rates and everything else. But the markets that we're serving are in a really strong state right now.
Chad Dillard - Analyst
Got you. That's helpful. And then maybe circling back on the AI topic. So how are you communicating to your customers the value creation from deploying AI like in a particular project? Are you having explicit conversations about sharing that?
Maybe just like talk about if you can even give me a particular example, that would be very helpful.
Robert Pragada - Chief Executive Officer, Director
Yes. Well, in order to do that, I think you got to go back and our clients' issues right now we're not solving for issues that were around or even contemplated 5 years ago, 10 years ago, 20 years ago. And so how we're articulating this to our clients is not in the form of thoughts or agents or people being replaced with AI figures. How we're discussing it is the use of data to give greater data insights to solve for complex issues and deliver outcomes at a faster and more predictable rate. That's how we're describing it to our clients, and our clients are co-creating with us in the platforms that we develop kind of part one.
The second, where we go to market is around AI advisory where we have, whether it be in the aviation space or it be in the transportation space. We've got a lot of our clients that want to understand how AI can enable their business even more. And so now with PA, we've now doubled the size of our AI, not just on the development side, but also AI consultancy component as well. And this is an AI consultancy just driving business transformation.
This is AI consultancy on how they can effectively serve their client base even greater. So we've -- the investment thesis around increasing our investment in PA coupled with what -- how PA is growing in that space across all the end markets and then us going to market together is really creating an exciting story going forward.

Andy Kaplowitz, Citigroup.

Bob, I just want to dig in on a couple of areas. I think historically, you guys have been very strong in semicon, particularly on the memory side. So what are you seeing in terms of investment there? Could we actually be an acceleration mode again? Like it seems like we are, but maybe any more detail there would be helpful.
Robert Pragada - Chief Executive Officer, Director
Absolutely. Short answer is yes. Yes, Andy, we are in acceleration mode. There are three main players around the world. One is American.
And the advances in high-bandwidth memory that the American provider is going to market with at record pace took 20 years during the traditional DRAM cycle to advanced nodes, that 20 years is now being shortened into two to three. And so to get the plant ready and delivering on those chips, is a big deal. So they've made some announcements in Idaho and New York, and we're squarely in the middle of those.
Andrew Kaplowitz - Analyst
And then, Bob, just following up on the water vertical. I mean, I think you answered a question earlier about environmental, water has been strong for you guys for a while. I get some questions occasionally about municipal spending, what eventually happens as IIJA starts to run down. So -- maybe you can talk about -- I think you've had good bookings here recently in water, but maybe you can talk about the longevity of the water infrastructure cycle as you see it?
Robert Pragada - Chief Executive Officer, Director
Yes. It's high single digits for us right now and how it's flowing through, Andy. And so maybe I'd kind of divide it between US and international. Maybe start with the real positive.
The result of the AMP8 cycle in the UK is driving kind of double-digit growth for us in the water market there in Europe, but we're also seeing strong tailwinds in the Middle East and in Australia. Australia has been a real highlight for us, both in water and in transportation. The municipal spending and the tie to IIJA never really was a strong one. IIJA really was focused heavily on transportation.
And so that has continued. And again, the whole water scarcity aged assets and just the sheer effects of climate. These aren't -- I'm not saying they're completely delinked from funding opportunities that state in local hat, but definitely have risen up on the priority list just because of the severity. So we see kind of a long-term tail on that.
Venkatesh Nathamuni - Chief Financial Officer, Executive Vice President
And Andy, if we could add to just what Bob said, there's been tremendous strength in bookings in water over the last several quarters, and we've highlighted some marquee wins that typically take multiple years to play out. So we see that pipeline continue to grow and the visibility for a multiyear period. So we feel really good about our water market overall.

Can I ask on critical infrastructure, really impressive performance relative to the end markets that you folks are clearly gaining share. Could you just double-click for us in terms of the drivers of the share gains? Is it just part of the market where you folks have higher concentration. Have you been on the right projects moving forward? Can you just expand on the drivers of what looks to be about 5, 6 points of end market outgrowth that you're delivering?
Robert Pragada - Chief Executive Officer, Director
Yes. Well, maybe I'd most succinctly talk about it in two main areas, Jerry. One is that our international business in transportation nothing has been strong, very strong. And that's been highlighted by really key wins that we've had in Europe, in the Middle East and in Australia. Australia, it's been really nice growth there as well.
Aviation and rail has really been the strong drivers there. We still do a lot of work on the highways work, but those two have been really strong drivers. And then the US, with continued growth in the aviation sector there, coupled with now some high-speed opportunities as well as faster rail in locations. We've been capturing share gain in that area as well.
So strong internationally, driven by aviation and rail and highways strong in the US, driven by Aviation and rail.
Jerry Revich - Equity Analyst
And if we could just pull on that market share threat into the AI theme, you folks on the semi plant side with the use of digital twins have been able to allow your customers to deliver projects really quickly. Just it sounds like based on your comments earlier on the call, Bob, you see yourselves as gaining share in that type of environment. What's the outlook for the broader industry structure as you see it 5 years down the line, 10 years down the line companies that look like Jacobs gain share to companies like Jacobs do more EPCM type work for an integrated solution like you're doing here on the data center example that you gave us.
Can you just talk about how you see this all playing out for the industry as a whole because you folks have been ahead of the pack in terms of your digital twin investments, et cetera?
Robert Pragada - Chief Executive Officer, Director
Yes. So maybe -- and just to clarify, Jerry, you were talking specifically about semi? Or were you talking kind of broader base across the kind of the tech landscape?
Jerry Revich - Equity Analyst
Bob, I was just talking across the broader tech landscape, right, in other words, you folks have clearly used digital tools and led the market gain share. And I just want your perspective on where you see the industry headed in five years now that the tools are getting better and better.
Robert Pragada - Chief Executive Officer, Director
Got it. Got it. So I kind of talk about it from our participation across the ecosystem of, call it, the electron landscape. So everything from the chip at the semi side through power and water, whether it be at the grid level or what eventually goes into the data center. Our participation across that ecosystem, I think, has been a big differentiator.
And so when I look out five years from now, the partnership that we have with NVIDIA and the kind of the tech relationship down to the chip design and how that affects utilities for these plants, whether it be with any of the high-bandwidth memory players or other traditional logic players. That's what's driving that out-year growth because as these plants -- no plant is the same as these plants are continuing to become more and more complicated, we're out in front of those.
Now you back all that up with design automation, AI tools in order to get greater data insights. And we're continuing to really -- and digital twins, like you said -- I'm sorry, Jerry, then that protective -- I don't know if I'm allowed to call it a moat, but I will, that moat starts to develop, and we go from there. So we're excited about where we're positioned. This is something we've been in for the better part of 40 years, and we see that going forward for another 40.
