In the past six months, AECOM's stock price declined significantly, impacted by disappointing fiscal Q3 2026 and Q2 2026 reports, which showed a 14.2% year-over-year revenue decline, weak full-year EBITDA guidance, and a substantial $337 million pre-tax charge related to a delayed legacy construction-management project, resulting in a GAAP net loss. Despite these setbacks, positive developments include a record total backlog of $27.8 billion (up 13%) and a book-to-burn ratio of 1.6x on new wins, indicating strong demand for its design and advisory services, alongside new infrastructure wins. An investigation into potential securities law violations was initiated in August 2026.
