A band this wide is itself the finding. When independent methods land far apart, they are reading a business whose value depends heavily on which lens you apply — volatile earnings, heavy reinvestment, or an asset base that cash-flow and asset-based methods score differently. That disagreement is information: it says the choice of method matters more than usual for ACM. Treat the median as one reading among several and compare the individual models below before acting.

What Is AECOM (ACM) Worth in 2026?

According to the CirclFi Deep Alpha Valuation Engine, AECOM's intrinsic value is estimated at $75.51, suggesting a +14.0% median upside from the current price of $66.24.
