AECOM shares declined 12.0% post-earnings, reflecting investor disappointment likely driven by emerging deceleration risks in key international transportation markets and lingering uncertainty related to the Middle East outlook, despite record backlog and raised profit guidance.

• Backlog reached a record high, up 8%, supported by a book-to-burn ratio of 1.2x, underpinning revenue visibility.
• Americas design segment, the most profitable, grew NSR by 8% and expanded segment operating margin by 50 basis points to 16.5%.
• Strong U.S. funding environments persist, with over half of IIJA funds remaining and a 50% pipeline increase in defense work, supporting growth.
• International segment growth was mixed: the UK saw a return to growth in water and energy, but transportation demand remains weak.
• The outlook was tempered by Middle East conflicts, introducing uncertainty despite the company raising full-year profit guidance for adjusted EBITDA and EPS by 7% and 14%, respectively.
