Approach 1: AECOM Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a business might be worth by projecting future cash flows and discounting them back to today’s value using a required rate of return.

For AECOM, the model used is a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The latest twelve month free cash flow is about $620.8 million. Analysts provide estimates out to 2027, with free cash flow for the year to 30 September 2027 projected at $884.5 million. Beyond that, Simply Wall St extrapolates cash flows, reaching a projected free cash flow of about $1,215.6 million in 2035, with each future year discounted back to a present value.

Adding these discounted cash flows together gives an estimated intrinsic value of about $117.36 per share. Compared with the recent share price of $90.32, the model implies AECOM trades at roughly a 23.0% discount to this intrinsic value, which indicates the shares appear undervalued on this DCF view.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests AECOM is undervalued by 23.0%. Track this in your watchlist or portfolio, or discover 49 more high quality undervalued stocks.

Approach 2: AECOM Price vs Earnings

For a profitable company like AECOM, the P/E ratio is a useful shorthand for how much you are paying for each dollar of current earnings. It is influenced by what the market expects for future earnings growth and how risky those earnings are perceived to be, which helps shape what might be considered a normal or fair P/E level.

AECOM currently trades on a P/E of 19.4x. This sits below the Construction industry average of about 32.1x and also below the peer average of 33.3x, which suggests the market is applying a lower earnings multiple to AECOM than to many of its listed peers.

Simply Wall St’s Fair Ratio for AECOM is 28.4x, which is its proprietary estimate of what the P/E might be given factors such as the company’s earnings profile, industry, profit margins, market cap and risk characteristics. This Fair Ratio can be more informative than a simple comparison with peers or the broad industry because it adjusts for company specific attributes rather than assuming all firms deserve the same multiple. Comparing AECOM’s current P/E of 19.4x with the Fair Ratio of 28.4x points to the shares looking undervalued on this earnings based view.

Result: UNDERVALUED
