Approach 1: Digital Realty Trust Discounted Cash Flow (DCF) Analysis

The Discounted Cash Flow model estimates what a company is worth today by projecting its future adjusted funds from operations and then discounting those cash flows back to a present value.

For Digital Realty Trust, the latest twelve month free cash flow is about $2.27b. Based on analyst inputs for the next few years, and then extending those trends further out, Simply Wall St projects free cash flow reaching about $4.12b in 2030. A full 10 year path of annual free cash flow in $ billions is used, with values discounted back using a 2 Stage Free Cash Flow to Equity model grounded in adjusted funds from operations.

Combining all those discounted cash flows results in an estimated intrinsic value of about $257.99 per share, compared with the recent share price of around $203.91. That implies the DCF model points to roughly a 21.0% discount, which suggests the shares trade below the modelled cash flow value.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Digital Realty Trust is undervalued by 21.0%. Track this in your watchlist or portfolio, or discover 63 more high quality undervalued stocks.

Approach 2: Digital Realty Trust Price vs Earnings

For a profitable company, the P/E ratio is a common way to think about what you are paying for each dollar of earnings. It helps you compare how the market values one set of earnings against another across similar businesses.

What counts as a “normal” P/E depends heavily on what investors expect for future growth and how much risk they see in those earnings. Higher expected growth or lower perceived risk can justify a higher P/E, while slower growth or higher risk usually means a lower multiple is seen as more reasonable.

Digital Realty Trust currently trades on a P/E of 56.12x. That sits above the Specialized REITs industry average of 16.47x and also above a peer group average of 40.82x. Simply Wall St’s proprietary “Fair Ratio” for Digital Realty Trust is 27.44x. This is an estimate of what the P/E might be given its earnings growth profile, industry, profit margins, market cap and risk factors.

This Fair Ratio goes further than a simple industry or peer comparison because it adjusts for company specific characteristics rather than treating all REITs or peers as equivalent. Comparing the current 56.12x P/E to the Fair Ratio of 27.44x suggests the shares trade at a richer multiple than this framework implies.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Digital Realty Trust Narrative

Earlier it was mentioned that there is an even better way to understand valuation, so Narratives bring this to life by letting you attach a clear story about Digital Realty Trust, including your own assumptions for revenue, earnings, margins and fair value, to a set of numbers that can be compared directly with today’s share price.

A Narrative on Simply Wall St connects three parts: the business story you believe, the financial forecast that flows from that story, and the resulting fair value estimate. All of this appears in one place within the Community page that millions of investors use.

This can make it easier to decide whether to buy or sell because you can see in one view whether your Narrative fair value sits above or below the current price. Your view then updates automatically as new information, such as earnings or news about AI data center projects, is incorporated.

For Digital Realty Trust, one investor might build a Narrative closer to the lower fair value of about US$110.45 per share, with more cautious assumptions around data center demand and profitability. Another might lean toward the higher fair value near US$201.03, reflecting stronger AI and cloud driven revenue assumptions and a higher future P/E. Comparing these side by side can help you decide which story you find more realistic.
