AECOM stock down 30% in six months amid $337M project charge and cash flow pressures

AECOM shares have fallen 30% over the past six months, underperforming the S&P 500's 16% gain and its industry peers. The infrastructure consulting firm faces significant near-term challenges, including a $337 million charge in its Construction Management business due to subcontractor productivity issues and project delays. Operating cash flow dropped to $169.2 million in the first nine months of fiscal 2026 from $625.5 million the previous year. The company now expects full-year free cash flow of approximately $300 million, with pressures continuing through the first half of fiscal 2027. Despite these headwinds, AECOM's backlog reached a record $27.8 billion, up 13%, supported by strong demand across transportation, water, energy and data centres. However, fiscal 2026 earnings estimates have declined to $4.48 per share, representing a 14.8% year-over-year decrease, before an expected 33.7% rebound in fiscal 2027.

AECOM wins Ireland's largest rail contract despite $337M charge wiping Q3 profit

AECOM has secured Ireland's largest railway contract as part of a joint venture with Jacobs to deliver MetroLink, the country's first fully segregated metro system. The project will connect North County Dublin, Dublin Airport, and the city centre through 16 new stations. The win comes despite AECOM reporting a $337 million charge that eliminated its third-quarter profit. The charge stems from a 2019 Construction Management project facing cost overruns due to lower subcontractor productivity. The project won't reach substantial completion until the second quarter of fiscal 2027. AECOM's total backlog reached a record $27.8 billion in the third quarter, up 13% year-over-year. International revenue rose 6%, with adjusted operating margin expanding 240 basis points to 14.3%. The company is pursuing claims to recover costs from the troubled project, though management acknowledges full resolution will take years.

Worley-led team to support next phase of Canadian pumped storage project.

Worley-led team to support next phase of Canadian pumped storage project. Canadian energy firm TC Energy has selected Worley, together with EllisDon and Aecom, to advance the next development phase of the 1,000MW Ontario Pumped Storage Project. The proposed multi-billion-dollar Ontario Pumped Storage Project (OPSP) is currently progressing through the planning and development phases, with the Impact Assessment Agency of Canada overseeing the federal Impact Assessment process. Last month, TC Energy announced that it had selected a team led by Worley, supported by EllisDon and Aecom, to advance detailed engineering, project design, cost estimates, execution planning and overall project readiness activities for OPSP. Located in Meaford, Ontario, the project could provide approximately 1,000MW of generation capacity and 10,600MWh of energy storage. If built, it would pump water from Georgian Bay to an upper reservoir during periods of low electricity demand and release it back through turbines during periods of high demand, generating electricity for the grid. In TC Energy's 2026 Initial Project Description, the OPSP reservoir is described as being located "close to Georgian Bay on top of the level plateau of the Niagara Escarpment, approximately 174m above Georgian Bay's surface and 2,300m from its shore". The reservoir would have a capacity of approximately 26 million m[3] and would be formed by constructing a 4.5km long ring dam around approximately 135ha of land. The pumped storage powerhouse could include four 250MW reversible pump turbine generators in underground chambers accessed by a tunnel. Potential construction methods for the powerhouse include underground mining and surface excavation methods. The lower inlet and outlet structure is currently envisioned as an underground ring-type structure on or below the lakebed, with multiple screened inlet and outlet ports located above the lakebed. Related questions you can explore with Ask GE, its new AI search engine. Aecom's Canada chief executive Richard Barrett said: "Ontario is entering a period of significant electricity demand growth, making long-duration energy storage increasingly important to a reliable and flexible electricity system. "The OPSP represents an opportunity to apply proven technology at a scale that can help meet the province's future electricity needs. We are proud to bring our Canadian and global hydropower expertise to this landmark project and help advance it toward an informed investment decision." Aecom will specifically support the advancement of the project's underground works and hydraulic systems to help optimise the design for constructability, operability and long-term performance.

AECOM, Jacobs JV to build Dublin's first metro.

AECOM, Jacobs JV to build Dublin's first metro. 2 hours An AECOM and Jacobs JV, supported by Ramboll and Nicolas O'Dwyer, has been appointed by Transport Infrastructure Ireland to deliver Dublin's first metro railway. The rail connection, between North County Dublin, Dublin Airport and the city centre, aims to support future growth, reducing congestion and enhancing mobility across Ireland's capital. The AECOM and Jacobs joint venture will support the procurement and delivery of the metro system, bringing integrated programme management, governance and risk management to one of Ireland's largest infrastructure investments. MetroLink is expected to become Ireland's first fully segregated metro railway and a critical component of the country's future transport network, supporting population growth, economic development and decarbonisation goals while improving connectivity across the Greater Dublin Area. The predominantly underground high-capacity, high-frequency system will include 16 new stations connecting Swords in North County Dublin with Dublin Airport and the city centre, while integrating with Irish Rail, Dublin Area Rapid Transit (DART) commuter rail, Luas light rail and BusConnects services to support a more connected and sustainable transportation network. The team will support TII through an integrated delivery model designed to enhance governance, manage interfaces across multiple contracts and provide transparency throughout the programme lifecycle. The team will help manage risk, improve certainty and support efficient delivery of the nationally significant infrastructure investment. The joint venture will be supported by affiliates Ramboll and Nicholas O'Dwyer.
