Will Gabrielski, Senior Vice President, Finance, Treasury and Investor Relations

Thank you, operator. I would like to direct your attention to the Safe Harbor statement on Page 1 of today's presentation. Today's discussion contains forward-looking statements about future business and financial expectations. Actual results may differ significantly from those projected in today's forward-looking statements due to various risks and uncertainties, including the risks described in our periodic reports filed with the SEC. Except as required by law, we undertake no obligation to update our forward-looking statements. We use certain non-GAAP financial measures in our presentation. The appropriate GAAP reconciliations are incorporated into our materials which are posted to our website. Growth rates are presented on a year-over-year basis unless otherwise noted. Any references to segment margins or segment adjusted operating margins will reflect the performance for the Americas and International segments. When discussing revenue and revenue growth, we will refer to net service revenue or NSR which is defined as revenue excluding pass-through revenue. NSR and backlog growth rates are presented on a constant currency basis, unless otherwise noted. Today's remarks will focus on continuing operations. On today's call, Troy Rudd, our Chief Executive Officer, will review our key accomplishments, our strategy and our outlook for the business. Lara Poloni, our President, will discuss key operational successes and priorities; and Gaurav Kapoor, our Chief Financial and Operations Officer, will review our financial performance and outlook in greater detail. We will conclude with a question-and-answer session. With that, I will turn the call over to Troy.

Troy Rudd, CEO

Thank you, Will, and good morning, everyone. I would like to begin by thanking our talented professionals across the globe. Through their dedication to our purpose of delivering a better world, we continue to create successful outcomes for our clients. Our teams are the best in the industry and we lead in every market sector in which we operate. To that point, earlier this year, ENR recognized AECOM as the number 1 ranked water design firm. We now hold the number 1 ranking in water, environmental engineering, transportation, and facilities design. Today, I'm also excited to share that we moved up 2 spots to number 2 in ENR's ranking of program management firms. This reflects our deliberate focus on extending our competitive advantages with program management, which is ideally suited for projects of increasing size and complexity. Based on the 20% growth in our program management pipeline in the third quarter, I am confident that we are on track to be number 1 in this category within the next year. Turning to our results. Our third quarter performance exceeded our expectations. As a result, we are increasing our earnings guidance for a second consecutive quarter. For the quarter, NSR increased by 8% to a new high. Our adjusted EBITDA and EPS increased by 16% and 23%, respectively and we delivered record quarterly margins. We also delivered strong cash flow in the quarter, and on a year-to-date basis, free cash flow has increased by 32%. Importantly, our backlog is strong and our pipeline is at a record high. This provides us with significant visibility and is consistent with our view that we are in the early innings of a multi-decade secular growth cycle across our markets. This visibility gives us confidence in our future, which underpins the increase in our fiscal '24 guidance. We now expect to deliver 21% adjusted EPS growth at the midpoint this year. Our performance and our outlook demonstrate that we've built a tremendous competitive advantage through our strategy, which is resulting in a more valuable company. This is evident in our 20% adjusted EPS CAGR from 2020 to 2024 and in our commitment to deliver double-digit annual adjusted EPS and free cash flow per share growth. To fully realize the value creation opportunity, we are continuing to allocate substantially all available free cash flow to share repurchases after investment in high-returning organic growth and dividend payments. To that end, we have repurchased $200 million of stock since the end of the second quarter, including $150 million since the close of the third quarter. We have more than $700 million remaining under our current board authorization and we will continue to take advantage of the disconnect between price and value. I would now like to review our strategic priorities. First, we are committed as ever to winning what matters. That is winning the key pursuits valued at greater than $25 million that enhance our visibility and expand the long-term earnings potential of our organization. Notably, our win rate is at a record level, securing $0.50 of every dollar we bid, and our success rate on large pursuits is even greater. Just this year, we have won 7 out of 8 program management pursuits, each valued at over $25 million. This brings our total to 19 out of the last 20 over the past 2 years. Across the enterprise, we are pursuing an unprecedented level of larger opportunities. In fact, the value of our larger pursuits expected to be awarded in 2025 is approximately 70% greater than at this time last year. This includes the growth in program management that I referenced earlier and strong trends in each of our other markets as well. In Water, our large pursuit pipeline increased by 45%. The pipeline in facilities design business, the majority of which is public sector, has increased by nearly 25%. The trends are also strong in Environment and Transportation. Second, we are enhancing our employee value proposition which has a very high payback. For instance, the number of employees enrolled in the leadership development program has tripled from just a few years ago. As a result, we are equipping our leaders and project managers with the best resources to promote our culture of technical excellence across the organization. These investments are directly linked to our voluntary attrition being meaningfully lower than the industry average and are a key element of winning what matters through our technical leadership. Third, we are leveraging our scale and capacity to create meaningful long-term operational efficiencies. For instance, the adoption of digital tools is growing across the company. As we detailed during our December Investor Day, we aim for 5% to 15% of our work hours to be delivered through scripts and code that we create by leveraging our extensive digital libraries. This will increase the capacity and extend our capabilities of our teams. We're also transforming how we work through AI by integrating AI into specific areas of our business, such as our bid and proposal process. Although it is early to fully measure the potential benefits of these technologies, the signals are quite positive. Overall, these investments are designed to strengthen our company and help us exceed our 17% long-term margin target. Fourth, we are focusing our best resources on the fastest-growing, highest value, and most resilient markets and clients to ensure that we fully capitalize on the opportunities ahead. This includes our 4 largest regions; the U.S., Canada, U.K. and Australia which generate approximately 90% of our profit. Also, our largest clients are growing at a rate that is several times faster than the rest of the business due to this effort. Finally, we are seizing new complementary high-value market opportunities. One example is the energy transition. Nearly every aspect of our business will be touched in one form or another by this long-term secular growth opportunity. Another great example is digital consulting. Our investments are growing rapidly for our infrastructure clients. Our revenue in this market has increased by 70% year-to-date and we estimate this to be a $50 billion addressable opportunity for AECOM over the next decade. Traditionally, this market has been dominated by management consulting and IT consulting firms. However, we are winning because of our superior technical expertise, trusted client relationships, and extensive capabilities that set us apart from these traditional competitors. Taken together, we remain very confident in our ability to deliver on our increased guidance this year and on our long-term growth targets which include our expectation for annual 5% to 8% net service revenue growth, as well as double-digit adjusted EPS and free cash flow per share growth. With that, I will turn the call over to Lara.

Lara Poloni, President

Thank you, Troy. Our strong performance highlights the effectiveness of our strategy and the competitive advantages from our unmatched technical expertise. We have built a backlog and pipeline of opportunities that reflect strength across nearly every market in which we operate and provide substantial visibility. In the U.S., IIJA funding is ramping up. In the U.K., the government continues to prioritize investments in infrastructure, led by the transportation and water markets. In Canada, both national and provincial funding commitments for infrastructure investment remain robust and our backlog in this market hit another record high this quarter. Across all our markets, the multitrillion dollar investment needed to address current and future infrastructure challenges is gaining momentum, particularly for areas such as urbanization, the energy transition, and sustainability and resilience. These drivers cut across all of our markets, and especially the water and environment markets which account for 35% of our revenue. For instance, urbanization is driving demand for clean drinking water, energy-efficient wastewater treatment solutions, and effective strategies for storing and reusing water supplies. The energy transition touches the environment and water sectors in various ways. This includes utilizing pumped hydro storage to enhance the value and reliability of renewable resources as well as addressing the water and environment-related impacts associated with mining the resources essential for electrification. Moreover, the rise in global flooding and droughts introduces new challenges prompting our clients to integrate sustainability and resilience more deeply into their planning and decision-making processes. A recent U.S. government report estimated that more than $630 billion of investment in water infrastructure is needed over the coming decades to meet these challenges, which illustrates the scale of the opportunity. Of note, this estimated spend is 2x the projected need from just 10 years ago and includes significant increases for stormwater management and wastewater treatment which plays to our strength. A prime example of our leadership in addressing this need is our involvement in the Pure Water Southern California program which aims to create a sustainable water supply by purifying treated wastewater. Our team is responsible for managing environmental compliance efforts and program managing the development of advanced purification facilities at the wastewater treatment plant, including approximately 60 miles of large diameter water pipeline infrastructure and pump stations. In addition, PFAS investment is ramping up, not only locally but globally. In fact, already in the fourth quarter, we secured one of our largest ever PFAS wins globally for a project in Australia. Across our number 1 ranked water practice, our pipeline of larger pursuits is up by 45% in just the last year alone which gives us confidence in delivering on our market share gain ambitions and goal of doubling our water revenue over the next 5 years. Importantly, these same dynamics are playing out across all of our market sectors and we are focused on capitalizing. With that, I'll turn the call over to Gaur.

Gaurav Kapoor, Chief Financial and Operations Officer

Thanks, Lara. I am proud of our team's performance which has allowed us to increase the midpoint of our full-year earnings guidance for the second time this year. This quarter was highlighted by strong organic revenue growth, further expansion of our industry-leading margins, and 23% adjusted EPS growth. A key driver of these successes has been our culture of continuous improvement and delivering industry-leading margins while reinvesting in the business. Turning to the Americas segment. Net service revenue increased by 8% and our adjusted operating margin expanded by 50 basis points to 19.3%. Americas backlog and pipeline of opportunities continued to be strong with a third quarter book-to-burn ratio of 1.1, reflecting our high win rate. Wins were highlighted by strength in transportation where we were selected for several more transformative projects in both the U.S. and Canada, as well as the environment business which is benefiting from all aspects of infrastructure investment growth. Turning to the International segment. Net services revenue increased by 7%. Our 11.7% adjusted operating margin set a new quarterly high and we remain confident in further expansion ahead. Our tremendous growth and margin enhancement in the International segment over the past several years has resulted in a 26% compounded profit growth rate since 2020. This is a direct outcome of our focus on higher-returning and lower-risk markets and fostering relationships with key clients and partners. Building on substantial growth we have delivered over the past 2 years, we expect continued growth from here even with the reprioritization of funding in the Middle East and the pause in the U.K., resulting from the July elections. Importantly, the core growth drivers across our international segments are firmly in place. In the U.K., the new government has outlined its commitment to investments in infrastructure, energy transition, and sustainability and resilience. For example, the government has already put in place a new National Wealth Fund designed to drive nearly $30 billion of investments to decarbonize heavy industry and spur activity in new growth areas. In addition, the record water investment through AMP8 is expected to accelerate in 2025 and beyond. In the Middle East, key projects underway are advancing and record levels of capital are being directed to support investments in World Cup and export-related infrastructure, where we are very well positioned. The Australian market is also strong with several key opportunities to be awarded in the coming quarters. Turning to our cash flow, balance sheet, and capital allocation. We delivered $273 million of free cash flow in the quarter and are on track with our guidance for at least 100% free cash flow conversion. Our cash flow has enabled the return of $407 million to shareholders this year, including $150 million of share repurchases already completed in the fourth quarter. Our balance sheet continues to provide a competitive advantage. Our net leverage was 0.8x exiting the third quarter and with our completed amendment to our credit facilities in the quarter, we will continue to benefit from low cost of debt and substantial available liquidity. Before discussing our raised financial guidance, I want to provide a brief update on the financial impacts from discontinued operations. After the second quarter earnings call, we entered into several agreements with our previously disposed off civil construction business. This included resolving outstanding litigation and providing limited financing to provide the time and capital needed for the Civil business to address its near-term liquidity challenges. Our support is in 2 forms: a $30 million revolving loan commitment and a noncash guarantee on other outstanding debt. As with all our capital allocation decisions, our choice to provide capital was driven by a returns-based assessment of different options. Importantly, the impact to AECOM, if any, is not expected to be material. Our balance sheet also includes 2 retained receivables for completed projects totaling approximately $250 million that we retained as part of our divestitures. While we can't predict the exact timing for these settlements, we are optimistic that both matters will result in positive cash events for AECOM and under no circumstance will these result in cash outflows. Concluding with our outlook. I'm pleased to report that our year-to-date outperformance has positioned us to increase our full-year adjusted EBITDA and EPS guidance. At our new guidance midpoints, we expect adjusted EBITDA and EPS growth of 13% and 21%, respectively.

Operator, Operator

Your first question comes from the line of Andrew Wittmann from Baird.

Andrew Wittmann, Analyst

I wanted to ask about the revenue outlook. It appears the pipeline prospects are strong, but I would appreciate more detail. The design only backlog you report is crucial for AECOM, and I’ve calculated that it has increased by 3% at the end of the third quarter. The long-term guidance mentions a minimum organic growth rate of 5%. I'm curious if there’s any correlation between these two figures, such as additional book and burn work or opportunities pending approval that could help ensure 2025 aligns with the long-term revenue guidance.

Troy Rudd, CEO

Thank you for the question, Andy. First, I want to highlight that in the third quarter, our international business faced some clients adjusting their priorities and funding, especially in the U.K. due to the recent election and change of government. This has led to a shift in government infrastructure investments, which caused a brief pause. Similarly, in the Middle East, we're observing clients realigning their expenditures. Rather than a decline, we view this as a repositioning of funds from completed projects and long-term initiatives to more urgent ones, like preparations for FIFA and the World Cup. Overall, we believe this reprioritization is temporary and does not alter our outlook on the future. We're optimistic as our backlog continues to grow at a rate faster than before, particularly in the international sector. In the Americas, backlog growth remains strong, and our pipeline has significantly expanded compared to the start of fiscal '24. This indicates that opportunities are increasing in the Americas, which fosters our confidence in future growth for the design business. Additionally, for the year-to-date, our book-to-burn ratio in the Americas is over 1.2x, and for the international business, it is above 1x. Considering these factors, we don't think it's prudent to draw too many conclusions from just one quarter regarding our expectations and future growth confidence.

Andrew Wittmann, Analyst

Appreciate that. I guess maybe just to build on that, I'd be curious with the record pipeline that you guys are citing today and your win rates staying at that around 50% range, which is up over the past. I was just wondering if you're seeing, Troy, anything from customers on like political risk or economic risk that's slowing down the conversion from the pipeline where they're asking for RFPs or what have you, to conversion into actual contracts. Is there any change at all? You mentioned the stuff in the U.K., the Middle East, I understand that. But anything more broadly than that or even in the Americas where we have the election season here?

Troy Rudd, CEO

Yes, Andy, it's a great point about our win rates. Actually, our win rates are at 50% or greater for the last 12 quarters. So that's been a bit of a change in the business. It's been fairly consistent. But more importantly, within our larger projects, and we've defined that as greater than $25 million, our win rate is significantly higher than that. And that's important because we've been transforming the work that we do in the business and the projects that we pursue, and they're larger. And so that actually does cause a change in the time it takes for an award to be made and to convert an award to contract and begin those projects. So larger projects are, in fact, a little bit longer in terms of the time to actually get working on them. So I don't know if it's necessarily markets that are causing a change in how long it takes to convert a bid to an award to a contract and to work. I think that might just be a function of how we've transformed the business and the size and the nature of the projects that we're pursuing and that we're currently working on. The other part of that equation, of course, is larger projects mean that you work on them for a lot longer and you have significantly more visibility, and it means that you also have significantly more upside or changes or change orders or additional work on those projects. So when you look at our backlog, because of the transformation, it also means that we actually have a lot more upside in the backlog that we stated that will come through change orders and additional work on larger programs or projects during the course of the future years.

Operator, Operator

Your next question comes from the line of Jamie Cook from Truist Securities.

Jamie Cook, Analyst

I guess 2 questions. Just the margin cadence that we've seen over the past couple of years. I mean, this year, your margins will be up, I think, 90 bps. I think you're up 50 bps from 2023 to 2022 relative to the longer-term guide of 20 to 30 basis points a year. Just given the strong performance we've had over the past couple of years, should we expect the margin growth to start to normalize more towards your longer-term goal of the 20 to 30 bps? Or are there still opportunities with some of the bookings that you're talking about? And these larger, more complex projects, maybe we can still see above-average sort of margin growth as we're looking out over the next 12 to 18 months? And then just my second question, Troy, just because some of the things that you talked about with larger, more complex projects, et cetera, should we expect the design backlog to be lumpier over time in terms of the growth versus sort of the steady growth you've seen over the past couple of years.

Troy Rudd, CEO

Thanks, Jamie. I'll let Gaur take the margin question, and then I'll cover the backlog question.

Gaurav Kapoor, Chief Financial and Operations Officer

Thanks, Troy. So you're right. Over the past 4 years, we have delivered on our margin target every time. And over that period, we've gone from being laggards in our peer group to being head and shoulders above everyone in margin delivery. So we have been and will always be very focused on delivering on our annual target because it is very important to us that every dollar we put into our backlog today is more valuable in the future as we deliver it. And for this management team, to your point, the Q3 results were strong, but it's just consistent with our expectations. And it's not surprising to us even while we continue on elevated business development spend in Q3 and year-to-date compared to our plan and I'm very confident that we will be delivering on the 90 bps increase that we had set out as a target year-over-year. And further, when you look at the backlog and pipeline growth opportunities that Troy just laid out earlier, it gives us great visibility for the upcoming future years. You combine it with our track record of executing on efficiency initiatives, I expect us to continue to deliver good, strong margin growth in future periods consistent with the target we had laid out, which is to get to 17% by the end of 2026, and then we're going to be going at 17-plus percent thereafter and we have a track record of delivering it.

Troy Rudd, CEO

Jamie, your observation about the backlog is spot on. The dollar volume of bids can be quite variable from quarter to quarter because we are actively pursuing larger opportunities, leading to an uneven distribution rather than a consistent and linear flow as seen with countless smaller projects. This year's second half is somewhat atypical due to the numerous federal government elections occurring worldwide, which introduces some instability as changing governments often result in shifting priorities. However, we do not see any decrease in the commitment to long-term infrastructure investments, including sustainable and resilient infrastructure, particularly for supporting a long-term energy transition. This ties back to your point about the variability, but it’s also crucial to acknowledge that these changes do not alter the underlying long-term trends, even if the situation appears more volatile.

Operator, Operator

The next question comes from the line of Sangita Jain from KeyBanc.

Sangita Jain, Analyst

If I can go back to margins. We know that you're kind of expecting revenue towards the lower end of your guidance, but your EBITDA is still higher. So can you point to any specific areas where you're seeing profitability exceed expectations? Or is it more broad-based, I would say?

Gaurav Kapoor, Chief Financial and Operations Officer

Sangita, this is Gaur. I'll answer that question. So our revenue growth is going to be within the range that we had forecasted to begin the year, 8% to 10%. Given the outline Troy has provided, we expect it to be in the lower end of the range right now. But what you're seeing is the competitive platform as a differentiator we have created at this enterprise, at this company over the last 4 years, it allows us to extract great value for our shareholders and for our employees. And this is driven through a lot of different things. It's our focus on making sure we provide and capture on the best growth opportunities in the market as laid out by our global program management, where we're delivering double-digit growth higher than what we had expected 3 years ago when we set into that organic investment profile. Our advisory and digital businesses continue to be very robust and responding to our clients' evolving needs. We're at the forefront of providing that. And then you combine that with our efficiency measures on our enterprise capability centers. Recall, this is where we provide great technical support to our teams where the labor markets are more abundant for us with our centralized support functions and other initiatives put forward. It really has created this great juggernaut of what we call a competitive differentiator in the marketplace from growth to execution and delivery.

Troy Rudd, CEO

I want to emphasize that our organic growth of 8% is a significant achievement. This level of growth is likely the best we've experienced in the company's history. More importantly, we are proud to have transformed that 8% organic growth into a 16% increase in earnings. By strategically deploying capital in a high-return and low-risk manner, we've managed to achieve a 23% growth in EPS. For the year, our EPS is projected to grow by over 20%. We are pleased that while we are growing the business organically, we are also accelerating profit growth, investing in our margins, and supporting the future of the business, which boosts our confidence moving forward.

Sangita Jain, Analyst

Got it. And if I can follow up with one on, Troy, you talked about elections globally and you talked about a record pipeline and larger bookings. Can you tie that all and tell us what you're seeing in the U.S. in particular, ahead of the election as you head into fiscal fourth quarter?

Troy Rudd, CEO

Sure. We aren't observing any significant changes in our pipeline in the Americas, with one notable exception being the New York metro market. The recent withdrawal of congestion pricing has impacted funding that was expected to support essential infrastructure investments, particularly for some of our larger clients. This situation is currently being addressed, as that infrastructure investment is necessary. So, this is the only area in our pipeline where we see some differences, which remain uncertain. However, across our entire U.S. business, our pipeline continues to grow. As for fiscal '25 and '26 in the Americas, that pipeline has been expanding based on what we experienced in '24. At this moment, we have not noticed any changes.

Operator, Operator

Your next question comes from the line of Andrew Kaplowitz from Citigroup.

Andrew Kaplowitz, Analyst

Troy and Gaur, can you talk about what maybe changed in your Americas margin between Q2 and Q3? Because I think you did 130 basis points better and only $30 million higher in sales and I think you still had higher business development expense in Q3. And then how should we think about Americas margin going forward? I know you want us to think about AECOM margins at the enterprise level but can margins still ultimately rise from current levels in the Americas in '25 and beyond.

Gaurav Kapoor, Chief Financial and Operations Officer

The Americas margin is aligning with our expectations. We take an annual perspective rather than a quarterly one, and we aim to achieve our targets for the Americas margin. In the third quarter, it's important to note that the second half of the year typically brings seasonal factors into play, including more workdays and labor hours, which helps distribute overhead costs across a larger base. Additionally, considering the strong backlog we've built over the past year in the Americas and the robust pipeline we have, we are well-positioned for success, especially with large projects that we are now executing effectively. Our labor is operating very efficiently on these projects, and I anticipate the Americas will maintain that culture of continuous improvement throughout the organization. Each year, we will keep progressing as we move forward.

Andrew Kaplowitz, Analyst

Helpful. Got it. And then, Troy, I think you mentioned, lumpiness is the word, to Jamie, as they get larger but is there any reason, given your pipeline of opportunity that you've been talking about in your current backlog that you really couldn't do the 5% to 8% organic growth in '25? And are you seeing any delays associated with the weaker macro in your private markets? I know you just mentioned congestion pricing in New York. Anything else that's changed quarter-to-quarter?

Troy Rudd, CEO

Firstly, regarding the changes from quarter to quarter, I’ve highlighted New York, the Middle East, and the U.K. We view the issues in these international markets as temporary. For New York, I believe the situation will also be temporary due to the substantial investments planned for infrastructure. I am optimistic that these challenges will be resolved. As for fiscal '25, it's too early for us to provide guidance. Nevertheless, based on our backlog, pipeline, and consistent win rate, we are confident in our ability to meet our long-term guidance for NSR growth.

Operator, Operator

Your next question comes from the line of indiscernible from UBS.

Unidentified Analyst, Analyst

Calling in for Steven Fisher. First question is, how do the margins in backlog compare to the margins you just posted for the quarter?

Gaurav Kapoor, Chief Financial and Operations Officer

Yes, thanks for that question. We don't provide that information as to the margin in backlog. Now what I will point out is we have the long-term margin growth targets of 20 to 30 bps every single year. But more importantly, in our Investor Day, we laid out, over the midterm, we do see our margin at the enterprise-wide going to 17% by the end of FY '26. So we'll be delivering at 15.6%, head and shoulders above anybody delivering anything in our marketplace right now. And we expect over the next 2 years as we exit 2026, we'll be at 17% and then margin to 17-plus percent. And I would like to take this opportunity again to maybe be redundant but I think it's really important. You look at our backlog record of our team, we have proven going from the bottom of the pack to top of the heap in delivering margins and we have a lot of confidence for all the reasons based on backlog, pipeline, and efficiency measures that we will be achieving it year after year and after year.

Unidentified Analyst, Analyst

That's helpful. And just my follow-up, what's the setup for spending on IIJA programs in 2025 at this point relative to 2024?

Troy Rudd, CEO

I can't provide a specific percentage, but I can share that we are seeing IIJA funding being utilized in projects within our pipeline. We have good visibility into this. As a rough estimate, we believe that approximately 30% of the IIJA funding will be deployed during this year, and that figure is increasing. However, I can't say for certain if the rate at which it's entering the market is accelerating. This is because, while our pipeline is expanding, it consists of funding from the IIJA as well as funding from state and local government clients and private clients. Overall, we observe growth in this area, and I expect the IIJA is contributing to the expansion of our pipeline.

Operator, Operator

Your next question comes from the line of Michael Dudas from Vertical Research Partners.

Michael Dudas, Analyst

Troy, maybe you can elaborate. You talked about your forays in digital consulting and the growth you've seen in the pretty large market over the next several years. Maybe some examples of what that is and how that differentiates and how that differs from your regular kind of consulting advisory work that you've been working for your clients?

Troy Rudd, CEO

Yes, certainly. I think Lara will answer your question.

Lara Poloni, President

Yes, sure. As projects become larger and more complex, which is an area where we excel, we have seen a 70% increase in programs involving digital consulting in our pipeline. Consequently, our revenues from digital infrastructure consulting have risen 70% year-to-date. Looking ahead, we view this as a $50 billion market opportunity over the next decade. This opportunity spans all of our sectors, particularly in areas like environmental remediation, transportation, and notably, water. We achieved significant wins this quarter, such as a $100 million data framework for the NHS in the U.K. Overall, we see this as a global opportunity with substantial long-term potential.

Michael Dudas, Analyst

Right. And then my follow-up would be, as you're looking at the pipeline in front of you and the backlog and conversion and the success of your organic growth, maybe you could talk about your staffing levels today, what you need to grow on an annual basis? And can you grow that at a lower rate than what your revenue, your backlog expectations are over the next few years, given some of the different dynamics and different services that you provide your customer base?

Gaurav Kapoor, Chief Financial and Operations Officer

Mike, this is Gaur. I'll take that question. Yes, you're correct. Our backlog shows that the Americas backlog over the trailing 12 months is up more than 1.2, and the international backlog has exhibited strong organic growth over the past two years. We're still achieving a book-to-burn ratio of over 1x, and our pipeline remains extremely strong across all areas. Your question about our labor is valid. This ties back to my earlier point about our distinct competitive platform, as the competition for talent in our industry is still very intense. However, we are one of the few companies that can leverage our scale to our advantage. We've outlined how we utilize our enterprise capability centers, which are not just detailed design centers but are located worldwide. Even where we no longer have any operational presence, there exists excellent technical talent that not only assists us in delivering large, complex projects but also enhances our ability to win projects globally due to their credentials. This is how we plan to manage our workforce while simultaneously focusing on attracting top talent onshore whenever possible.

Lara Poloni, President

Yes, I would like to add that attrition is down, and we are performing well below industry benchmarks and our competitors in all key markets. This, combined with the optimism in our pipeline, shows a 70% year-on-year increase in large pursuits. This growth benefits all areas of our business as we take on more complex projects that utilize our diverse services.

Operator, Operator

And that does conclude the question-and-answer session. I would like to turn the floor back over to the CEO, Troy Rudd, for closing remarks.

Troy Rudd, CEO

Great. Again, thank you, everyone, for joining the discussion today. And I'm going to end the way I started, which is to thank our teams for the extraordinary performance in serving their clients and their communities over the quarter. We look forward to talking to you in another 3 months. Thank you.

Operator, Operator

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