Bert Subin
Senior Vice President, Investor Relations
Thank you, operator, and welcome, everyone. Following market close, we issued our earnings announcement, filed our Form 10-Q, and posted a slide presentation on our website, which we'll reference during the call. I would like to refer you to slide two of the presentation for information about our forward-looking statements, non-GAAP financial measures, and operating metrics. Now let's turn to the agenda on slide three. 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 third 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, as well as our updated outlook. Finally, Bob will provide closing remarks, then we'll open up the call for questions. With that, I'll turn it over to our chair and CEO, Bob Pragada.
Bob Pragada
Chair and Chief Executive Officer
Good afternoon, everyone, and thank you for joining us to discuss our third quarter 2026 business performance. We delivered strong results in Q3. I'll quickly highlight a few key takeaways. First, adjusted EPS grew approximately 14% to $1.84, supported by more than 8% adjusted net revenue growth, all organic, and more than 100 basis points of year-on-year margin expansions. Second, INAF posted nearly $2.1 billion in net revenue, a 10% increase year over year, and a quarterly record for the segment. And third, our backlog grew 27% to $29 billion, setting another new record with a trailing 12-month book-to-bill of 1.4 times on gross revenue and 1.2 times on net revenue. As we look ahead, we see continued strong underlying business momentum as reflected by our third consecutive guidance raise for FY26, which Venk will walk through in more detail shortly. Turning to slide four, we provide a detailed overview of the quarter. We're very pleased with our Q3 results as strong operating performance paired with our lower share count drove the sixth straight quarter of double digit growth in adjusted EPS. Our margin profile continues to trend higher with our business achieving an adjusted EBITDA margin above 15% in Q3, up over 100 basis points year over year, and up almost 200 basis points when compared to the same period in 2024. The combination of strong annual margin expansion, high single-digit organic growth, and continued share repurchases enabled by strong free cash flow generation has created a powerful earnings growth algorithm. Further, we are seeing convergence of backlog growth and overall revenue growth, and we are positioned to deliver another strong bookings performance in Q4. Turning to slide five, I'd like to highlight a few notable project awards from the third quarter. In Water and Environmental, Jacobs is selected to provide program management and technical environmental services to the U.S. Navy's Environmental Restoration Program, primarily across the Mid-Atlantic and Puerto Rico. The work involves restoring contaminated sites, including PFAS and munitions-related projects, with the goal of reducing health and environmental risks and returning these sites to beneficial use. Thank you so much for joining us. were selected to deliver Central Utah Water District's Strawberry Highline Improvement Project, which will modernize roughly 40 miles of aging canal infrastructure through new pipelines, a pump station, a regulating reservoir, and related facilities. By converting a historic open canal into a modern pressurized system, the project will improve long-term water reliability for agricultural and municipal users while supporting regional growth and enhanced recreation along the corridor. It's part of the district's broader NEBO Regional Water Project, an approximately $1.5 billion program designed to sustain a doubling of the area's population in the coming decades. This also includes the South Utah Valley Regional Water Treatment Plant, where Jacobs is already under contract to lead design and engineering during construction. Shifting to Life Sciences and Advanced Manufacturing, Jacobs was awarded a sole source EPCM contract by HUD-8 to deliver Beacon Point, the company's second AI data center campus in the U.S. Located in Texas, the multi-phase campus is designed to support one gigawatt of total capacity. This award is a follow-on to HUD-8's Riverbend campus in Louisiana, where Jacobs is also leading program deliveries. will apply proven design elements from that project and deploy our data center digital twin to simulate critical assets, helping to de-risk commissioning and reduce time to first revenue by accelerating the deployment of AI workloads. Initial energization is targeted for 2027. Winning a repeat sole source contract at this scale reflects the confidence clients place in Jacobs to deliver complex AI infrastructure with speed, safety, and certainty. It also builds on our standing as Engineering News Records' number one data center firm, a sector where we see substantial runway as AI investments increase. And finally, PA is supporting the UK Royal Air Force's Optimize initiative, enabling RAF leaders to use data-driven insights to further strengthen operational readiness and decision-making in an increasingly complex environment. The work turns data into confident, evidence-led decisions that support the RAF's readiness and it reinforces our standing as a trusted delivery partner in the defense sector, delivering high-tempo programs that have real operational impact. Now please turn to slide six. Given the growth tailwind we are seeing from AI investments, I wanted to take a moment to quickly highlight our position in the AI infrastructure build-up. We've been serving data center clients since the 1990s and have long-standing relationships with semiconductor manufacturers that span over 50 years. Significant capital is being deployed to build AI data centers, and we have been able to grow our addressable market by expanding our scope of services, which now range from technical advisory and design to digital twins and full program delivery. Thank you for joining us. As of Q3, the direct AI build-out represented 11% of our adjusted net revenue, up approximately 100 basis points from last quarter, and our pipeline of future opportunities continues to grow meaningfully. Now I'll turn the call over to Venk to review our financial results in further detail.
Venk Nathamuni
Chief Financial Officer
Thank you, Bob, and good afternoon, everyone. Please turn to slide number seven, where I'll walk through our results for Q3. Gross revenue increased more than 34% year over year, and adjusted net revenue, which excludes pass-through revenue, grew by over 8%. Q3 adjusted EBITDA was $367 million, up 17%, with our margin at 15.2%, or 109 basis points higher year over year. This resulted in adjusted EPS increasing 14% year over year. Consolidated backlog was up more than 27% year-over-year to a record $29 billion with our trailing 12-month book-to-bill at 1.4 times. Book-to-bill was strong again in Q3, driven by good awards activity across our end markets with standout performance in the advanced manufacturing, environmental, and transportation sectors. Additionally, on a year-over-year basis, Net revenue and gross profit in backlog increased 11% and 14% respectively during Q3. We're demonstrating faster organic growth in the business today, and strong recent awards activity positions us well as we look ahead to fiscal year 27. Regarding our performance by end market in infrastructure and advanced facilities, let's turn to slide number eight. At a high level, we continue to see strong growth rates in life sciences and advanced manufacturing, as well as in critical infrastructure during Q3. Focusing on life sciences and advanced manufacturing, net revenue grew 24% in Q3, our highest growth rate since we began reporting end markets in late 2024. Strong performance in the data center and semiconductor sectors contributed to substantial year-on-year growth and we anticipate that this trend will continue in Q4. We're seeing high demand for new projects across life sciences and advanced manufacturing, setting us up well for the new fiscal year. Shifting to critical infrastructure, net revenue increased 9% year-over-year. We continue to expect critical infrastructure to grow in the mid to high single-digit range over the medium term. Net revenue growth in our water and environmental end market was a little more than 1%. Net revenue growth for water remains strong, and, as we indicated last quarter, we did continue to face year-over-year headwinds in the environmental sector. On a positive note, we're forecasting growth for the water and environmental end market to sequentially improve in Q4 based on good awards activity in the quarter. In summary, strong life sciences and advanced manufacturing performance during Q3 was complemented by good demand across the majority of our sectors. Moving now to slide number nine, I'll provide a brief overview of our segment financials. In Q3, INAF operating profit increased 14% year over year on 10% net revenue growth. PA Consulting operating profit increased 2% on flattish revenue and operating margin again came in strong at about 22%. Both segments saw only a minor operating profit growth impact from foreign exchange during the quarter. Focusing on PA, the segment experienced some temporary disruption from the recent change in governmental leadership in the UK, which delayed project start dates. Importantly, we are already seeing a return to normal, and our forecast indicates solid quarter-on-quarter revenue growth in Q4, supported by recent awards activity, new project commencements, as well as performance quarter-to-day. Now moving on to slide 10, we provide an overview of cash generation and our balance sheet. For Q3, we generated $541 million in adjusted free cash flow, which removes the impact of $110 million in payments related to proceeds for the PA transaction, as we had indicated last quarter. This brings year-to-date adjusted free cash flow to $633 million. We will not make adjustments to free cash flow in Q4 and will return to providing guidance for reported free cash flow margin in fiscal year 27. Focusing on capital returns, we remain aggressive buyers of our shares during Q3 to take advantage of the dislocation in our share price. As a result, our total repurchases through Q3 rose to $614 million, which combined with dividends paid puts us on track to return more than 100% of free cash flow to our shareholders for the second consecutive year. This brings total shared repurchases since the beginning of fiscal year 25 to $1.4 billion, and we see continued runway moving forward given our strong outlook for free cash flow. Shifting now to the balance sheet, at the end of Q3, our net leverage ratio declined to 1.8 times, achieving our target for net leverage to be below 2.0 times a quarter early, and we still plan to delever to approximately 1.5 times by the end of fiscal year 27. Please turn to slide 11 for our updated fiscal year 26 outlook. We're increasing our fiscal year 26 adjusted net revenue growth range to 9.5% to 10% year over year, narrowing our adjusted EBITDA margin range to 14.7% to 14.8%, raising our adjusted EPS range to $7.20 to $7.30 and raising our adjusted free cash flow margin forecast to 8%. Notably, our outlook for fiscal year 26 now implies nearly 19% year-on-year growth in adjusted EPS at the midpoint. As it pertains to Q4, we expect our adjusted EBITDA margin to be approximately 16%, with year-over-year net revenue growth of approximately 14%. Furthermore, we expect our tax rate to be roughly 27.5% and our quarterly free cash flow to be approximately $150 million. Overall, we're very pleased with our year-to-date performance and our Q4 outlook highlights that we expect a strong finish to fiscal year 26. With that, I'll turn the call back over to Bob.
Bob Pragada
Chair and Chief Executive Officer
Thank you, Venk. In closing, I'd like to express my gratitude for the trust our clients continue to place in Jacobs and to our more than 47,000 talented employees for their continued commitment to delivering excellence. We're tracking very well heading into the final quarter of the fiscal year with strong Q3 performance enabling us to increase the midpoint of our full year adjusted EPS outlook for the third consecutive time. Our backlog is at record level, and our pipeline continues to expand, positioning us for profitable growth in FY27 and beyond. Operator will now open the call for questions.

We ask that you pick up your handset when asking a question for optimum sound quality, and if muted locally, please remember to unmute your device. Please stand by while we compile the Q&A roster. Your first question comes from the line of Andy Kaplowitz with Citigroup. Your line is open. Please go ahead.
Andy Kaplowitz
Analyst, Citigroup
Good afternoon, everyone.
Bob Pragada
Chair and Chief Executive Officer
Hi, Andy. Good afternoon.
Andy Kaplowitz
Analyst, Citigroup
Barbara Banks, so backlit growth has obviously been accelerating over the last several quarters. I think you mentioned 1.2 times book to go on net revenue, as you said. So I know it's early to talk about FY27, but your exit rating Q4 will be in a double digit at 14%. So Does that mean it's possible to grow FY27 net revenue as fast or faster than FY26, or at least at this point, give much higher visibility than usual toward that normal algorithm of mid to high single-digit growth that you have?
Venk Nathamuni
Chief Financial Officer
Yeah, Andy, I'll take the question. Yeah, so, you know, obviously, as you pointed out, good solid growth in Q4 that we're projecting and good growth for the full year. You know, certainly our backlog is in a really good position. I think, you know, we will defer specifics on the growth algorithm for fiscal 2017 on the next call. But suffice it to say that, you know, looking at our current background position, we feel pretty good about growth, you know, at least in line with the long-term average that we put out there.
Andy Kaplowitz
Analyst, Citigroup
Okay, that's helpful. And then, Bob, you had comments about sort of the data center business and life sciences, advanced manufacturing in general. It does keep increasing as a percentage of NSR. Maybe how are we thinking about that sector now versus your investor day a year and a half ago, whatever it was? Can you grow that business double digits for the foreseeable future based on what you see and maybe the share gains that you've had?
Bob Pragada
Chair and Chief Executive Officer
Yeah, Andy, we absolutely can. It's a growth engine right now that is deep and broad for us with the entire cadet ecosystem. And if we look all the way from kind of what we're doing in the high bandwidth memory chips, the water and power requirements that are feeding the data center, and then the complexity that's going into the data center, our share is increasing. And the clients that we're working for have got long pipelines ahead. So the answer is absolutely yes.
Andy Kaplowitz
Analyst, Citigroup
Very nice. Thanks, guys. Thank you.

Your next question comes from the line of Sangeeta Jain with KeyBank. Your line is open. Please go ahead.
Sangeeta Jain
Analyst, KeyBank
Great. Thank you so much for taking my questions. One, I want to ask on water and environment. It seems like last quarter you had a lot of good wins, a couple of them, Bob, you highlighted in your prepared remarks. How should we think about the scope of some of those bookings and the Thank you for joining us.
Bob Pragada
Chair and Chief Executive Officer
and then going into FY27 we're positioned extremely well to be on those growth rates that we highlighted during the investor day of that mid to high single digit growth for water and environmental and the water sector continues to be high single digit growth for us and in the pipeline as well as the forward outlook is very bright so we're excited about the sector.
Sangeeta Jain
Analyst, KeyBank
Got it. And then maybe one for Venk. Your SG&AS percent of sales in 3Q was lower than it has been in a very long time. And I'm wondering if there was anything one time or if it's just a function of what you've been saying that you're going to grow your OPEX at a slower pace than your revenue and that's starting to show maybe.
Venk Nathamuni
Chief Financial Officer
Yeah, Sangeeta, that's exactly right. You know, as our revenues continue to accelerate over the last several quarters and based on the guidance we've provided, we made a commitment to spend less than the revenue growth rate. And that's exactly what we're seeing in terms of operating leverage. And you'll see more of that coming through in Q4 as well.
Sangeeta Jain
Analyst, KeyBank
Got it. Thank you so much.
Venk Nathamuni

Your next question comes from the line of Stephen Fisher with UBS. Your line is open. Please go ahead.
Stephen Fisher
Analyst, UBS
Thanks. Good afternoon. A nice uptick there in the book to bill in the quarter. So as you guys look at your pipeline, how should we think about that book to bill from here? It seems like the growth is poised to accelerate. So with that faster burn, how sustainable do you think, you know, say 1.5 times or better is as you accelerate and how lumpy do you think it's going to be from here?
Bob Pragada
Chair and Chief Executive Officer
Yeah, Steve, I think if you look at the gross revenue book to bill versus the net revenue book to bill, let me kind of segregate those. The lumpiness in the gross revenue book to bill, where we would have a 1.5, a 1.6, you probably remember last year we had a 1.7 for a quarter, that's going to come up and down as some of these larger full program delivery jobs are booked. But the 1.1 to 1.3-ish Net revenue growth, pretty consistent.
Stephen Fisher
Analyst, UBS
Okay, sounds good. And then wondering if, Bob, you could give us an update on two things. One, Middle East activity in general, how you're managing that over there, and just international overall. Is the pace of that business picking up? Clearly, you've had some good wins. Just kind of curious of how those two things are developing.
Bob Pragada
Chair and Chief Executive Officer
Yeah, so Steve, maybe I'll take the second part first and then hone in on the Middle East. Internationally, we've done well. We're kind of in that 9% growth rate internationally, and that is probably more skewed a little bit to Australia, New Zealand, and Asia. The Middle East is stable, and we've continued to do well there. But I'd say the European area is Thank you. Your next question comes from the line of Jamie Cook with Truist. Your line is open. Please go ahead.
Jamie Cook
Analyst, Truist Securities
Hi, congrats on a nice quarter. I guess just two questions. One, Venk, there's still, you know, we're, you know, one quarter left. There still implies a significant ramp, you know, Q3 to Q4, which makes sense, like given the top line growth of 14% you're talking about. But I guess why so much variability to 10 cents around the fourth quarter? What would be the drivers behind, you know, the low end versus the high end of the guide? And then my second question, I guess, you know, sort of what struck me about the quarter is, You know, with the margin uplift, then I guess the implied, you know, the 15% and then implied margins going to 16% in the fourth quarter. As I think about the trajectory for 2027, we're thinking about a world where organic growth is accelerating and margins can expand. Is it fair to say more of the margin uplift would come from IANF versus PA Consulting or any comments you want to make around that? Thank you.
Venk Nathamuni
Chief Financial Officer
Yeah, first of all, thank you for your comments, Jamie. No, obviously really good quarter. So I'll split the response into two halves. One is just focused on the net revenue growth as well as the margin expansion. So on the net revenue growth, we guided to about 14% for the quarter. As you know, we have an extra week in the Q4. So that in and of itself accounts for about, call it 67%. So when you normalize it, we are growing at 8% for the quarter. So given the fact that we grew 7.8% or 8.3% in Q3, we see good line of sight to be able to grow the 14% for Q4. That's number one. Thank you so much for joining us. Thank you very much for joining us. and what we're guiding for in Q4 is 16%. So really good line of sight to be able to achieve that with the increased utilization that we talked about as well as increased use of global delivery. So a really good visibility into achieving those targets for both revenue as well as EBITDA margin.
Bob Pragada
Chair and Chief Executive Officer
And Jamie, I think on the question that you had with regards to 27 and where we see that continued margin expansion, I'd say it's pretty balanced that we would continue to get it from both INAF as well as PA Consulting because we're right in the middle of the cost synergies that we're working on with PA Consulting. Just as a reminder, PA Consulting does have the highest margins in that space. So, you know, we're continuing to grow on a base that's really high.
Operator
Conference Operator
Thank you. Your next question comes from the line of Andrew Whitman with Baird. Your line is open. Please go ahead.
Andrew Whitman
Analyst, Robert W. Baird & Co
Yeah, great. Thanks for taking my question. So I just, I think I heard a comment that you said in the fourth quarter, you're going to report free cash flow without any adjustments. And that's great. Is there a similar comment that you can make like that related to your income statement? I know that obviously, over a year ago, you announced some actions for the IAF segment. But now, Bob, you just mentioned that you're kind of integrating PA. So What should the investment community expect in terms of income statement adjustments between GAAP and non-GAAP? And not just maybe for 4Q, but how long are you going to continue to recognize something there and when can those two converge? Thanks.
Venk Nathamuni
Chief Financial Officer
Yeah, Andy, I'll take that question. I would say, obviously, you've seen with this Q3 print, the gap between GAAP and non-GAAP EPS was primarily driven by just a tax item. But overall, you've seen a pretty significant, you know, convergence between our gap and non-gap numbers, except for the PA acquisition. So from that standpoint, we feel pretty good about the quality of the earnings and we will continue to make additional progress in Q4 and beyond. You'll see it from both the P&L side as well as in the free cash flow side. And, you know, we've already taken M&A off the table. So, you know, you don't have to. Got it.
Andrew Whitman
Analyst, Robert W. Baird & Co
I guess just on my follow-up then, I wanted to dig in on the environmental side. It obviously sounds like you had some wins here in 3Q that are going to help that growth rate improve in 4Q. I just was hoping you'd be a little bit more specific. Is there a general context to something? Is this state and local? Is this federal money flowing better? I mean, there's lots of different things that you do in this. Thank you for joining us.
Bob Pragada
Chair and Chief Executive Officer
as a result in the quarter was over 1.3 just for the environmental business. So that balance between private and public, we're holding true to it because in the public sector, those things that you just mentioned with regards to PFAS and the DOD continuing to go back to some of those regulatory items that got paused in 2025, we're capitalizing on that work too. So going into FY27, we're feeling confident that our environmental business will return back to the levels that we previously had. Great. Thank you.

Your next question comes from the line of Chad Dillard with Bernstein. Your line is open. Please go ahead.
Chad Dillard
Analyst, Bernstein
Good evening, everyone. So question for you guys on the infrastructure and advanced facilities business. Looks like on a constant currency basis, margins are up about 50 basis points. Can you talk about some of the moving parts there? How much is mix? How much is pricing? How much is leverage from technology? And then as we're thinking through our 2027 bridge, how do you think about that opportunity going forward?
Venk Nathamuni
Chief Financial Officer
Yeah, so Chad, thanks for the question. So I'd say, you know, as you pointed out, good expansion in margins, both sequentially as well as on a year-to-year basis. As you may recall, when we announced our margin trajectory at the February 2025 investor day, we laid out specific things in terms of the drivers of that margin. I'd say we've shown, as Sangeeta pointed out earlier, Thank you very much. Really good progress in global delivery, especially with our life sciences and advanced manufacturing businesses use a lot of global delivery implementation. So that's driving a lot of the margin expansion. I'd say on the mixed side, you'll see more of an impact coming in FY27 and beyond. But operating leverage and global delivery are the bigger drivers in the first, you know, probably four or five quarters since we announced the targets. So we're on track in terms of margin expansion. And just for everybody's benefit, you'll recall that in fiscal year 25, we increased our margins by 110 basis points. And in fiscal year 26, at the midpoint of the guidance that we provided, that'll represent another 90 basis points of margin expansion. So 200 basis points of margin expansion, which we think is industry leading. And we have lots more margin expansion ahead of us as well.
Chad Dillard
Analyst, Bernstein
Great, that's helpful. And then second question is on data centers. So with the shift from 34 volt to 800 volt architecture, are you starting to see those sorts of data centers coming through your design pipeline? How does the design intensity change when you're making that shift? Any call you can give on that?
Bob Pragada
Chair and Chief Executive Officer
Yeah, there's complexities that are going on, Chad, that I'd say is increasing our scope. So, you know, that 800 volt DC solid state transformer is a big deal as has been well publicized. But I'd say I wouldn't point to that as the single source of that inflection point. The complexity and all of the utility requirements to feed the next generation of chips is increasing the complexity as well as the scale. And so that's where kind of It's in the sweet spot of Jacobs. And so, you know, if we look at the clients that we're working for, not just the hyperscalers, but also the neoclouds, you know, we're on that journey with them. And hence, you can see the results in our performance.
Chad Dillard
Analyst, Bernstein

Andrew Whitman
Analyst, Robert W. Baird & Co
Good afternoon, gentlemen. Good afternoon, Mike. Good afternoon, Mike.
Michael Dudas
Analyst, Vertical Research Partners
Bob, just maybe you could share some further thoughts on critical infrastructure and the tone of the types of business and what areas, you know, say with highway, maybe any brief comments on what may happen out of the next IIJA bill. And on PA, you know, with the change in government should be helpful, but anything With the integration over the past several months and how that could drive some more, you know, growth and some maybe the business with your current customers in the U.S. or other parts of the world to help drive, be helpful on the margin and also the growth for PA itself.
Bob Pragada
Chair and Chief Executive Officer
Sounds great. So a lot there, Mike. Let me kind of take one at a time. With regards to critical infrastructure, again, really solid growth. Just as a kind of a recap, that vertical contains our transportation business, energy and power, and cities and places. Our transportation business continues to be a real growth vector for us in all geographies and growing at a high single digit rate. I'd say the subsectors that are channeling that growth Thank you for joining us. predominantly in the U.S. around our T&D efforts, and I'd say outside the U.S. more on the generation side. And so if you think Sudolink or MarinusLink, you know, the renewables effort that's going on outside the U.S. has really been a nice growth trajectory for us. And then in cities and places, nice growth in the U.S. That cities and places team has some really, really strong building design capabilities, which we're able to not only apply to venues, but also has been with the resource needs that we have in data centers. That team has really been facilitating that growth that we're seeing in the data center business. I'd say probably the one area that we continue to monitor is a bit of a, I'd say, temporarily pause in the Middle East, still grew in the Middle East overall because of our utility work. But that would be the only area where I'd say A little bit of a pause, but definitely some pipeline work that would show upside next year. On IJA, we actually feel, we've been saying this for a while, with a possible extension going into December. You know, we feel like the funding flows coming from IAJ will continue. We've always said that there was always a two to three year lag from the expiry date, just as monies are obligated and then spent, we're still kind of at that 50% level spent. And so going into the midterms and coming out of the midterms and Everything that's being set up for Build America 250, you know, hopefully next year. The funding levels have been pretty solid as a result of those stimulus bills and will continue on, feeding all those things that I aforementioned around transportation. I'd say the areas where we're starting to see some real growth, again, notwithstanding my comment in Q3 on the kind of the temporary disruption that we're already seeing come back in July. Defense and security in Europe as the UK MOD has taken a leadership position on what an independent Europe defense posture looks like. PA is right in the middle of that. And the synergies with the U.S., with Jacobs, in the INAF business on setting up that defense infrastructure, whether it be ports and maritime or manufacturing facilities for the defense primes, is something that we've already started to see some nice progress there. And then transportation in the U.S., PA's got a strong presence in the U.K., and that's serving as a nice synergistic value as we look at the U.S. and the revenue synergies coming out of the PA relationship. So hopefully that gives you kind of a broader overview. Excellent, Bob. Thank you.

Andrew Ozion
Analyst, Wells Fargo
Hi, everyone. Good afternoon. Thank you for taking my question. This is Andrew Ozion for Jerry Revich. I just wanted to ask, last quarter you saw a significant expansion in the AI-specific data center infrastructure pipeline. I was curious if we can get an update on how that's progressing this quarter, how much of that pipeline is awarded or in backlog, and what's kind of the conversion rate that you're embedding into your guidance and maybe even into next year?
Bob Pragada
Chair and Chief Executive Officer
Yeah, maybe I'll take the front part of that and then Venk, you can take kind of how much of that is in backlog. So Andrew, our backlog growth just in the data center space has been significant. And I'd say kind of in the order of doubling over the period of time, the pipeline has gone up 3x. So the visibility that we see before it was probably six to nine months, we're getting visibility into the pipeline that extends out two to three years. So this is something that we see. And again, we're being selective because there is also a lot of speculative work that's out there. So the work that we are pursuing, let me back up. Winning, Executing, and Continue to Pursue are those where they're established customers of ours that we've had for a while. The NeoCloud providers that are coming in are normally backed by folks that we've known for a long time within the hyperscale world. So overall, you know, really strong trajectory in the data center space.
Venk Nathamuni
Chief Financial Officer
Yeah, and I've extended beyond data centers into just the overall AI ecosystem. You recall last quarter we said it was roughly 10% of our business. Now it's at 11% and the growth is actually accelerating. So we are doing a good job of converting that backlog into real revenue. and that's driving not only growth for us in Q4 but we expect significant growth in fiscal 27 which will quantify. I also want to add to this the previous question about revenue synergies. Obviously AI is a big part of what PA does as well in terms of implementing agentic AI for not only their clients but it's an opportunity for us to also use it internally both within the PA ecosystem as well as the Jacobs ecosystem. So AI is really a big driver of our growth for us. And you've seen that being demonstrated in terms of our revenue growth, but also over time with margin expansion.

Thank you. I appreciate that. You know, I guess secondly, are customers kind of still indicating that the U.S. semiconductor construction activity is accelerating? And maybe what are some of your early thoughts for FY27 on that front?
Bob Pragada
Chair and Chief Executive Officer
Thank you. Short answer, Andrew, is absolutely yes. Our customers are pushing us to accelerate those designs. And we're working for the largest high bandwidth memory chip manufacturer in the U.S. today. So that pipeline continues to grow. And now with the announcements that you've heard from Intel moving forward, you know, as we've publicly stated, we've been the engineer of record for Intel for a couple of decades. And in that relationship, we stayed with them during this kind of slower time. And we're starting to see that pipeline grow going into 27.
