AECOM Stock Falls 30% in the Past Six Months: Is a Rebound Ahead?
AECOM (ACM) stock has dropped 30.1% in the past six months due to project execution issues, delayed starts, and cash-flow pressures. The company reported a $337M pre-tax charge in Q3 2026 and expects cash flow to remain under pressure into fiscal 2027.
