Approach 1: AECOM Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model takes estimates of future cash the company may generate and discounts those amounts back to today, aiming to translate a stream of future cash flows into a single present value per share.

For AECOM, the latest twelve month Free Cash Flow is about $620.8 million. The DCF model here uses a 2 Stage Free Cash Flow to Equity approach, combining analyst inputs and extrapolated projections. For example, Simply Wall St uses analyst estimates such as $400 million in 2026 and $884.15 million in 2027, then extends those cash flows out over 10 years using gradual growth assumptions.

After discounting these projected cash flows back to today, the model arrives at an estimated intrinsic value of about $107.36 per share, compared with the recent share price of $81.47. On this basis, the stock screens as 24.1% undervalued relative to this particular cash flow scenario.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests AECOM is undervalued by 24.1%. Track this in your watchlist or portfolio, or discover 51 more high quality undervalued stocks.

Approach 2: AECOM Price vs Earnings

For profitable companies, the P/E ratio is a useful way to think about what you are paying for each dollar of earnings. It links the share price directly to current earnings, which many investors keep as a core reference point alongside cash flow work like the DCF.

What counts as a “normal” P/E often reflects how the market views a company’s growth potential and risk. Higher growth or lower perceived risk can justify a higher P/E, while slower growth or higher risk typically goes with a lower multiple.

AECOM currently trades on a P/E of 17.52x, compared with an industry average of 51.57x and a peer average of 33.00x in the Construction space. Simply Wall St’s Fair Ratio for AECOM is 28.64x. The Fair Ratio is a proprietary multiple that aims to capture what investors might pay for the stock given factors such as its earnings growth profile, industry, profit margins, market cap and specific risks.

Because the Fair Ratio brings all of those company specific features into one number, it can be a more tailored yardstick than simply lining AECOM up against peers or the broad industry.

With the current P/E at 17.52x and the Fair Ratio at 28.64x, AECOM screens as undervalued on this metric.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your AECOM Narrative

Earlier it was mentioned that there is an even better way to understand valuation. Narratives put a clear story behind your numbers by linking your view on AECOM's revenue, earnings and margins to a financial forecast and then to a fair value that you can compare with the current price.

On Simply Wall St's Community page, Narratives are an accessible tool that helps you see how different assumptions translate into different fair values. They update automatically when new news or earnings arrive, and show why one investor might see AECOM closer to US$152 while another focuses on a view nearer to US$101 based on their own expectations and risk focus.
