The investigation concerns whether the Company and/or members of its senior management may have violated federal securities laws or engaged in other unlawful business practices.[LEARN MORE ABOUT THE INVESTIGATION]What Happened?On May 11, 2026, AECOM reported its second quarter fiscal 2026 results. The Company reported operating cash flow of approximately $4 million, down 98% year over year, and negative free cash flow of approximately $27 million.

The Company also stated that collections in the Middle East had already recovered in the fiscal third quarter and reaffirmed its full-year free cash flow guidance.On May 12, 2026, AECOM filed its quarterly report on Form 10-Q, which disclosed that significant claims recorded in contract assets and other non-current assets were approximately $680 million as of March 31, 2026, compared with approximately $400 million as of September 30, 2025. On the earnings call, management stated that the relevant claims related to two projects bid in fiscal years 2019 and 2020, and acknowledged that the claim-resolution process had taken longer than expected. On this news, the price of AECOM shares declined by $9.55 per share, or approximately 12%, from $79.50 per share on May 11, 2026 to close at $69.95 on May 12, 2026.What Should I Do?At this stage, no lawsuit has been filed.
