Any reference 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 growth rates are presented on a constant currency basis unless otherwise noted. 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. This performance stems from the dedication of our professionals, unmatched technical expertise, high-returning organic growth investments, trusted client relationships, and strong market trends. We set new records for NSR margins, EBITDA, EPS, backlog, and pipeline. As a result, we are confident in raising our annual financial guidance for the third consecutive time this year.

Organic NSR growth accelerated to 6%, led by 8% growth in the Americas, our highest margin segment. Importantly, we delivered a 17.1% segment adjusted operating margin, which is a new record for the organization. First, we have demonstrated consistently that through our returns-based capital allocation policy, investments in organic growth initiatives have the highest returns. This includes not only standing up and accelerating the growth of our program management and advisory businesses, but also the record level of business development investment we make quarter-after-quarter.

What went well
  • Third quarter results surpassed expectations, setting new records for NSR margins, adjusted EBITDA, adjusted EPS, backlog, and pipeline, prompting AECOM to raise its fiscal 2025 guidance for the third consecutive quarter.
  • Organic NSR growth accelerated to 6%, led by 8% growth in the Americas, the company's highest-margin segment, with growth also increasing across most large international markets.
  • Segment adjusted operating margin reached a record 17.9%, up 90 basis points year-over-year, exceeding AECOM's long-term target more than a year ahead of plan with no extraordinary items in the margin.
  • Adjusted EBITDA and adjusted EPS grew 10% and 16% in the quarter (up 9% and 20% year-to-date), while year-to-date free cash flow increased 27% to a new all-time high on industry-leading earnings-to-cash conversion.
  • Backlog rose both sequentially and year-over-year to a new all-time high, marking the 19th consecutive quarter with a book-to-burn ratio above one, and the pipeline hit a record high for the fifth consecutive quarter.
  • The company won more than 50% of the value it bid, including a more than 80% success rate on its largest pursuits, and returned nearly $240 million to shareholders year-to-date ($2.7 billion since September 2020).
What went wrong
  • In Australia and Asia, near-term budgetary constraints led to a pause in larger transportation awards, weighing on near-term revenue trends despite long-term demand drivers remaining in place.
  • International NSR grew only 3% as strength in the U.K. and Middle East was partially offset by a decline in Australia.
  • Full-year organic NSR growth is now expected to land within the guidance range but trend toward the lower end, as strong water-market projects are longer in duration and less impactful to near-term revenue than the large civil projects completed last cycle.
  • The Q4 adjusted EBITDA margin guidance implies a slight sequential step-down from Q3's record levels, contrary to normal seasonality, as management leans into elevated business development expense to capitalize on the record pipeline.
  • Share buybacks in the quarter were notably light versus prior periods, drawing analyst questions, though management attributed this to cash-flow timing (cash arrives late in the quarter, with repurchases following in Q4).

Earnings Call Themes & Trends

TopicPrevious mentionCurrent periodTrend
Program management & advisory expansionStanding up advisory and program management businessesAdvisory grew double digits with a goal to double it to $400 million of NSR within three years as the next $1 billion platform; AECOM won nearly 90% of its largest program management pursuits this year and remains on track for 50%+ of revenue from program management and advisory over time.
Data center / AI market demandEstablished global data center practiceGlobal data centers practice doubled NSR over the last two years; U.S. data center investment projected to triple by 2030, with AECOM positioned across advisory, program management, and design to address land, power, and water constraints in 40+ countries.
Internal AI & automation deploymentBegan investing in AI ~18 months agoAI is already having a favorable impact on margins and results across how AECOM runs the business and delivers work; management expects a material, visible impact over the next two to three years, complementing rather than replacing its people and Enterprise Capability Centers.
U.S. federal & infrastructure fundingIIJA funding ramping; post-election agenda uncertaintyOnly 36% of IIJA funding targeted to AECOM's markets has been spent; the Big Beautiful Bill adds tax incentives plus $150 billion of mandatory defense spending (DoD is the largest single client) and aviation/Coast Guard funding, while state DOT budgets are forecast to hit a record high in 2026.
International markets (U.K., Middle East, Australia)The U.K.'s new 10-year infrastructure strategy commits £725 billion; the Middle East navigated a reprioritization toward World Expo and World Cup infrastructure in Saudi Arabia with UAE strength; Australia/Asia saw a near-term pause in larger transportation awards.
Returns-based capital allocation & capital returnsConsistent returns-based policyPolicy unchanged; nearly $240 million returned to shareholders YTD ($2.7 billion since September 2020), net leverage of 0.6, low cost of debt, and no maturities until 2029; buybacks follow free-cash-flow generation and will step up in Q4.
Enterprise Capability CentersMid-to-high single-digit share of total labor hoursStill in the mid-to-high single digits of delivered labor hours, with a path to middle-double-digits over the short-to-medium term, providing a continued margin tailwind alongside AI.

Q&A Summary

Sabahat Khan (RBC Capital Markets) asked for specifics on the U.S. market across the private and public sectors, and whether conditions stabilized during the second calendar quarter after earlier-year noise.
Rudd said post-election agendas and funding are now becoming clear in the U.S. (as well as Canada, U.K., and beginning in Australia), with stability around the new administration's infrastructure agenda; funding from the Big Beautiful Bill, reduced regulation, and a focus on long-term U.S. investment are supporting a more stable market, and state DOT transportation spending is expected to rise again next year.
Khan (RBC) followed up on the drivers of margin improvement and how much upside remains.
Kapoor credited the professionals and a DNA of cost improvement, plus investment in high-returning organic growth (business development running ahead of plan, 19 straight quarters of book-to-burn >1), early-stage benefits from the infrastructure advisory business and Enterprise Capability Centers (still mid-to-high single digits of labor hours), and AI already providing a lift; he emphasized the 17%+ target was raised because significant opportunity remains.
Adam Bubes (Goldman Sachs) asked for an update on AI and automation initiatives and how long until they move the needle on utilization or margins.
Rudd said AECOM began deploying AI about 18 months ago, using it both to run the business and to change how work is delivered; it is already impacting margins and results, and management expects a visible, material, favorable impact over the next two to three years, extending its people's capabilities and confirming more margin upside remains.
Bubes (Goldman Sachs) noted the Q4 EBITDA margin guidance implies a slight sequential step-down versus normal seasonality and asked what was driving it.
Kapoor confirmed it reflects a deliberate increase in business development expense to capitalize on the record pipeline across all end markets and regions, noting that such organic investments have consistently generated outsized returns and margin-trajectory growth over the last six years.
Andy Wittmann (Baird) asked whether this year's roughly 70 bps of margin improvement (more than double the normal 20-30 bps) represents a pull-forward of next year's margins or a higher base to build from.
Rudd said it is premature to guide next year but stressed the margins are not a pull-forward; they represent the true run-rate in the business and backlog, and significant upside still remains based on investments made and planned.
Wittmann (Baird) asked why buybacks were light in the quarter and how the balance sheet and capital deployment stand.
Kapoor said there is no change in capital allocation policy; cash in this business arrives at the end of the quarter, so buybacks follow free-cash-flow generation — cash generated in Q3 will be deployed in Q4, and more will follow as additional cash is generated.
Andy Kaplowitz's team (Jose, Citi) asked whether AECOM can sustain a book-to-burn above one in the current environment and how durable its high win rates are.
Rudd said past performance is not a perfect predictor but the 19-quarter track record reflects underlying conditions to repeat it — a healthy pipeline in areas of strength, a high win rate from a large sophisticated global team, strong and healthy markets, and greater clarity on government funding agendas.
Citi also asked about the water and environment advisory business introduced in Q1 2025 and its growth prospects.
Poloni said the business grew double digits, doubling in scale toward a $400 million NSR target over three years to become the next billion-dollar platform, with positive client feedback, strong wins, and good hiring momentum.
Sangita Jain (KeyBanc) asked how shifting work to overseas technical centers intersects with AI and whether there is a risk of over-investing if AI takes over tasks.
Rudd said the two work well together — client-facing, on-the-ground work will not change, and AI supplements both on-site teams and Enterprise Capability Centers regardless of location, so AECOM is investing deliberately to build on existing strengths.
Jain (KeyBanc) also asked about NSR trending to the lower end of guidance and early thoughts on next year.
Kapoor confirmed full-year NSR will be within range but toward the lower end, with Q4 growth expected to pick up (helped by work days), and said backlog, contracted backlog, wins, and book-to-burn give confidence that the 5%-8% long-term algorithm remains a good range for next year even before the planning process is complete.
