Aecom's shares fell to $60.35, marking a 52-week low, after the engineering and consulting firm reported a net loss of $0.65 per share for its third quarter of fiscal year 2026. This loss was primarily driven by a $377 million pre-tax loss from a 2019 construction project facing subcontractor delays and cost overruns. Additionally, Aecom's revenue slipped 14% year over year, and management slashed its full-year adjusted EPS guidance to $3.95-$4.15 per share (down from $5.90-$6.10) and free cash flow estimate to $300 million (down from $400 million).
