AECOM (ACM) Q3 2026: Backlog Surges 13% Amid $337M Construction Management Charge
AECOM's third quarter was marked by record backlog growth and robust design business wins, despite a significant $337 million pre-tax charge from delayed construction management projects. The company’s strong international margins and solid book-to-burn ratio underpin confidence in long-term growth, while cash flow is pressured by legacy project completions extending into early 2027.
Summary
- Backlog Expansion and Market Leadership: Record backlog growth driven by strong wins and expanded project scopes.
- Construction Management Headwinds: Delays and productivity issues led to a sizable charge and cash flow impact.
- Margin and Cash Flow Resilience: International margin gains and positive free cash flow support ongoing investments.
Business Overview
AECOM is a global infrastructure leader providing professional services across advisory, design, engineering, program and construction management. The company generates revenue primarily through its Americas and International segments, with a focus on markets including transportation, water, environment, energy, and buildings. Its business model blends design services with construction management, supported by a growing backlog and diversified client base.
Performance Analysis
The quarter’s headline financials were weighed down by a $337 million pre-tax charge related to delayed completion of a large construction management (CM) project, leading to an operating loss and net loss for the period. However, excluding this charge, AECOM demonstrated solid operational performance with adjusted EBITDA and EPS rising 5% and 11% year-over-year, respectively. Net service revenue (NSR) growth was supported by a 6% increase in the Americas design business and a 4% rise internationally, particularly in the UK and Australia.
The company’s backlog climbed 13% to a record $27.8 billion, fueled by record quarterly wins totaling $4.2 billion and a strong 1.6 book-to-burn ratio, indicating robust future revenue visibility. The Americas design business posted a 1.8 book-to-burn ratio, reflecting strength across transportation, water, environment, and facilities sectors. Meanwhile, the international segment’s backlog rose 28%, led by growth in the UK and Middle East markets.
- Margin Pressure from Business Development: Americas segment margin declined due to elevated business development spend and slower CM project ramp-up.
- International Margin Expansion: International segment margins improved 240 basis points, driven by growth in higher-margin Australia and UK markets and early AI deployment benefits.
- Cash Flow Impact: Despite the charge, the company generated positive free cash flow of $55 million, with expectations of $300 million for the full fiscal year.
Overall, the quarter underscored the resilience of AECOM’s design business and international operations, while highlighting near-term challenges in CM project execution and cash flow timing.
Executive Commentary
"We are disappointed by the loss we took this quarter on the Construction Management project. The project is nearing completion, but lower subcontractor productivity is driving a delayed completion and a higher estimated cost to complete. This project was bid in 2019 under terms and conditions that would not clear our substantially transformed risk processes today. Beyond this, the quarter included several key highlights, including record wins and an all-time high backlog, which make us very confident in the health of the business."
Troy Rudd, Chief Executive Officer
"Our 1.6x book-to-burn and 13% backlog growth are tremendous accomplishments for a business that expanded. Advisory, program management, and early AI wins are transforming client interactions and with it our ability to bring unrivaled solutions. Not only are we winning more with existing clients, opportunities are now emerging in new markets where our scale and technology are opening new avenues for growth."
Gaurav Kapoor, Chief Financial and Operations Officer
Strategic Positioning
1. Risk Management Transformation in Construction Management
AECOM has significantly tightened its risk controls and leadership in CM, eliminating design-build P3 projects from its portfolio following lessons learned from the problematic projects. The company now applies a rigorous review process and predominantly pursues guaranteed maximum price contracts, limiting risk exposure primarily to fees rather than project costs.
2. Focused Investment in Growth Markets and Capabilities
Investments in advisory services, program management, and AI-driven technology are expanding AECOM’s addressable market and enhancing client value propositions. This strategic pivot enables entry into new sectors such as healthcare, commercial buildings, and data centers, diversifying revenue streams and deepening client relationships.
3. Robust Backlog and Book-to-Burn Ratio as Growth Engines
The record backlog and strong book-to-burn ratios across Americas (1.8x) and International (1.4x) segments provide multi-year revenue visibility. Large recompetes, especially in environmental services, and expanded project scopes underpin this momentum, supporting the company’s organic growth target of 5% to 8% annually.
4. Margin Expansion Driven by International Segment
International markets, especially Australia and the UK, are delivering higher-margin growth supported by improved utilization, restructuring benefits, and early AI adoption. This margin strength offsets some Americas segment pressures and is central to AECOM’s goal of achieving 20%+ segment margins by fiscal 2028.
5. Capital Allocation Prioritizing Organic Growth and Dividend Stability
Despite near-term cash flow headwinds from legacy CM projects, AECOM maintains a disciplined capital allocation strategy focused on funding organic growth initiatives and sustaining its dividend program. The company anticipates deleveraging post-project completion and resuming share repurchases as market conditions permit.
Key Considerations
Investors should weigh the ongoing impact of legacy construction management projects against the company’s broader operational strengths and strategic initiatives.
- Construction Management Cash Flow Drag: The $337 million charge and expected $500 million cash burn in early fiscal 2027 will constrain free cash flow and elevate interest expense.
- Backlog Quality and Visibility: Record backlog and book-to-burn ratios provide strong revenue visibility, but delayed project starts in CM temper near-term growth.
- Business Development Investment: Elevated BD spend impacts margins temporarily but supports high win rates and long-term growth.
- International Growth Momentum: Continued expansion in Australia, UK, and Middle East infrastructure markets drives margin and revenue gains.
- Risk Controls and Portfolio Discipline: Exclusion of high-risk design-build P3 projects in CM reduces future risk exposure and improves project quality.
Risks
AECOM faces risks from delayed project completions and subcontractor productivity issues in legacy CM contracts, geopolitical uncertainties affecting international markets, and potential margin pressure from ongoing elevated business development costs. The protracted nature of claim recoveries and litigation related to the charged projects adds cash flow uncertainty through 2027.
Forward Outlook
For Q4 2026, AECOM expects:
- Continued NSR growth in design businesses, with Americas design projected to grow over 7% adjusted for workdays.
- Normalization of Americas segment margins with expected improvement over prior year.
For full fiscal 2026, guidance includes:
- Adjusted EPS between $3.95 and $4.15, and adjusted EBITDA between $935 million and $965 million, reflecting the construction management charge.
- Free cash flow of approximately $300 million, down from prior expectations due to project cash burn.
- Excluding the charge, NSR of $7.65 to $7.7 billion, adjusted EPS of $5.90 to $6.10, and adjusted EBITDA of $1.275 billion to $1.305 billion.
Management anticipates growth in construction management in the second half of fiscal 2027 as backlog ramps and legacy projects complete, supporting the long-term organic growth algorithm of 5% to 8% annually.
Takeaways
AECOM’s Q3 results reveal a company navigating near-term execution challenges while reinforcing its strategic foundation for sustained growth.
- Backlog Strength Validates Market Position: Record backlog and book-to-burn ratios across segments confirm strong client demand and competitive positioning.
- Construction Management Charge Highlights Risk Management Evolution: The sizable charge underscores past risk exposures but also signals the effectiveness of revised risk frameworks and leadership changes.
- International Segment Drives Margin Expansion: Growth in Australia and UK markets, combined with AI-enabled efficiencies, support margin gains and the 20%+ margin exit target by fiscal 2028.
Conclusion
AECOM’s third quarter was a tale of two narratives: a significant construction management charge dampening near-term results, juxtaposed with record backlog growth and margin expansion in international markets. The company’s disciplined risk management, strategic investments in technology and advisory services, and robust backlog provide a solid foundation for returning to normalized growth and cash flow in fiscal 2027 and beyond.
Industry Read-Through

The company’s success in expanding advisory and AI-driven services signals a broader industry shift towards integrated, technology-enabled infrastructure solutions. Investors and industry participants should monitor how firms balance legacy project execution risks with investments in innovation and market diversification to sustain long-term growth.
