AECOM ACM continues to reinforce its long-term growth case through record backlog and strong project wins across transportation, water, environment and facilities. In the third quarter of fiscal 2026, total backlog increased 13% year over year to a record $27.8 billion, supported by $4.2 billion of quarterly wins and a 1.6x book-to-burn ratio. Management said this stronger visibility supports its long-term target of 5%-8% organic net service revenue (NSR) growth through fiscal 2029.
The underlying demand picture remains broad. In the United States, AECOM’s water pipeline expanded 30%, while its federal defense pipeline also increased about 30%. State and local infrastructure activity remains healthy, and less than half of IIJA funding in AECOM’s core markets has been spent. The company is also seeing accelerating private-sector demand from data centers. Internationally, backlog rose 28%, while Australia posted double-digit growth and backlog increased more than 40% year over year.
Near-term execution remains the key constraint. Slower construction management project starts and weakness in Middle East hospitality and tourism weighed on fiscal 2026 NSR growth. AECOM also recorded a $337 million charge tied to a legacy construction management project, while those projects are expected to pressure cash flow through the first half of fiscal 2027.
Still, the design business is providing support, with Americas design organic growth running near 7% year to date on a workday-adjusted basis. The bigger test will be how quickly AECOM converts its record backlog into revenues, particularly in construction management, where large projects can take 12-18 months to ramp. With strong pipelines, record wins and improving multiyear visibility, the company has a solid foundation to sustain its 5%-8% organic growth algorithm as delayed projects move into execution.
Infrastructure Backlogs Highlight a Competitive Growth Landscape
AECOM’s record backlog and 5%-8% organic growth target come as peers are also benefiting from strong infrastructure and project demand. EMCOR Group, Inc. EME is seeing broad-based strength across data centers, institutional, manufacturing and water-related markets. In the second quarter of 2026, EMCOR’s remaining performance obligations reached a record $17.14 billion, up 44% year over year, with 95% of the increase generated organically. EME’s Network and communications, led by data centers, remained a major driver, while bookings were also strong in water and wastewater, health care and institutional projects.
Fluor Corporation FLR is another relevant rival, with exposure to large-scale infrastructure, energy, mining, nuclear and data-center-related projects. Fluor secured more than $6 billion of new awards in the second quarter of 2026, lifting backlog to nearly $27 billion. FLR’s pipeline includes about $30 billion of potential mining and metals awards over the next 18 months, while power opportunities tied to data-center growth are expected to support meaningful backlog additions in the first half of 2027.
