Smart Money Convergence

ACM does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.

13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.

On August 10, 2026, AECOM issued a press release reporting its financial results for the quarter ended June 30, 2026. That release is attached to this 8-K as Exhibit 99.1, and the company explicitly notes it is “furnished” rather than “filed” for SEC purposes. AECOM operates on 52/53-week fiscal periods ending on the Friday nearest each quarter-end, but presents results as if they ended on the calendar quarter dates for clarity. The excerpt doesn't include actual revenue or profit figures—just the announcement itself.
