Approach 1: American Tower Discounted Cash Flow (DCF) Analysis

A DCF model looks at the cash American Tower is expected to generate in the future, then discounts those cash flows back to today to estimate what the stock could be worth now. Here the model uses adjusted funds from operations as a proxy for free cash flow to equity.

American Tower currently has last twelve month free cash flow of about $5.0b. Analyst and extrapolated estimates used by Simply Wall St project free cash flow reaching about $6.6b by 2030, with a detailed path of annual forecasts and extrapolated figures out to 2035 included in the model.

Discounting those projected cash flows back to today using the 2 Stage Free Cash Flow to Equity model gives an estimated intrinsic value of $271.04 per share. At a current share price of around $187.53, the model output indicates the stock trades at a 30.8% discount. On this DCF view, that suggests the stock may be undervalued.

Approach 2: American Tower Price vs Earnings

For a profitable company like American Tower, the P/E ratio is a useful way to relate what you pay for the stock to the earnings it currently generates. It lets you see how many dollars investors are paying today for each dollar of earnings.

What counts as a "normal" or "fair" P/E depends on how fast earnings are expected to grow and how risky those earnings are. Higher expected growth or lower perceived risk can justify a higher P/E, while slower growth or higher risk usually points to a lower P/E.

American Tower currently trades on a P/E of about 30.1x. That is higher than the Specialized REITs industry average P/E of roughly 15.9x, but below the peer group average of about 45.2x. Simply Wall St also calculates a proprietary "Fair Ratio" of 33.8x for American Tower, which reflects factors such as earnings growth expectations, profit margins, industry, market cap and company specific risks.

This Fair Ratio can be more informative than a simple comparison with peers or industry averages because it adjusts for the quality and growth profile of the business rather than assuming all companies deserve the same multiple. Comparing the current P/E of 30.1x with the Fair Ratio of 33.8x suggests the stock may be trading at a discount to that implied level.

Result: UNDERVALUED
