Why Aecom Stock Crashed to a 52-Week Low This Week

Aecom shares plummeted 17.9% to a 52-week low after the engineering and consulting firm reported a $377 million pre-tax loss on a single problematic construction project signed in 2019. The loss turned what should have been a profitable Q3 into a net loss of $0.65 per share, prompting management to slash full-year guidance. While the company's record $27.8 billion backlog signals strong demand, investors worry about execution risks and potential additional project losses through mid-2027.
