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

A DCF model estimates what a company could be worth by projecting its future adjusted funds from operations, then discounting those cash flows back to today in dollar terms.

For Digital Realty Trust, the model uses a 2 stage Free Cash Flow to Equity approach based on Adjusted Funds From Operations. The latest twelve month free cash flow is about $2.27b. Analysts provide explicit free cash flow estimates out to 2030, with Simply Wall St extrapolating further using its own assumptions for the later years.

The projections show free cash flow of about $4.11b in 2030, with a series of annual estimates between 2026 and 2035 that are discounted back to present value. When all those discounted cash flows are added together, the model arrives at an estimated intrinsic value of US$255.44 per share.

Compared to the recent share price of US$194.58, this implies the stock trades at a 23.8% discount to the DCF estimate, which suggests the shares screen as undervalued on this model.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Digital Realty Trust is undervalued by 23.8%. Track this in your watchlist or portfolio, or discover 53 more high quality undervalued stocks.

Approach 2: Digital Realty Trust Price vs Earnings

For profitable companies, the P/E ratio is a useful way to link what you pay for each share to the earnings that support it. A higher or lower P/E often reflects how the market weighs factors like expected earnings growth and risk, with faster growth or lower perceived risk typically lining up with a higher “normal” P/E, and slower growth or higher risk with a lower one.

Digital Realty Trust currently trades on a P/E of 50.77x. That sits above the Specialized REITs industry average P/E of 16.30x and also above the peer group average of 38.04x. This suggests investors are currently willing to pay a higher price per dollar of earnings compared with many similar companies.

Simply Wall St’s Fair Ratio for Digital Realty Trust is 28.13x. This is a proprietary estimate of what a reasonable P/E might be, given factors such as the company’s earnings growth profile, profit margins, industry, market capitalization and specific risks. Because it is tailored to the company rather than being a simple comparison, the Fair Ratio can offer a more nuanced reference point than broad industry or peer averages. Comparing the Fair Ratio of 28.13x with the actual P/E of 50.77x indicates the shares screen as overvalued on this metric.

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 meet Narratives, a simple way for you to attach a story about Digital Realty Trust to your numbers by linking your view on its future revenue, earnings and margins to a financial forecast, a fair value estimate and then a clear comparison between that fair value and the current price.

On Simply Wall St's Community page, Narratives are an accessible tool used by millions of investors. Each Narrative sets out a thesis, translates that into explicit assumptions and a fair value, and then helps you decide whether the price you see on screen looks high or low relative to that story.

Narratives update automatically when new information such as news or earnings is added, so your fair value view does not stay frozen. You can see in real time how changes to Digital Realty Trust's data center expansion plans, funding costs or demand expectations might affect the numbers you care about.

For example, one Digital Realty Trust Narrative on the platform currently arrives at a fair value of about US$110.45 per share with assumptions for revenue growth of 7%, a profit margin of 12% and a future P/E of 80x. Another Narrative, using different assumptions and a discount rate of 7.79%, reaches a fair value of about US$201.03 per share, showing how two investors can look at the same company, tell different stories and land on very different price tags.

For Digital Realty Trust, here are previews of two leading Digital Realty Trust Narratives:

Fair value in this narrative: US$201.03 per share

Upside versus the recent US$194.58 share price: about 3.2% below this fair value level

Revenue growth assumption: 10.39% a year

• Focuses on strong leasing backlog, AI and cloud demand, and a hyperscale fund that together support higher future revenue and funds from operations.
• Highlights European and U.S. development projects plus sustainability efforts as ways to improve scale and potentially support margins over time.
• Builds a fair value around analyst assumptions for revenue of US$8.2b, earnings of US$897.5m by 2029, and a future P/E of about 102x, while flagging execution, financing conditions and competition as key risks.

Fair value in this narrative: US$110.45 per share

Overvaluation versus the recent US$194.58 share price: about 76.2% above this fair value level

Revenue growth assumption: 7%

• Accepts that AI, cloud and digital transformation are important demand drivers, but pairs them with concerns about interest costs, competition and energy prices.
• Assumes revenue growth of 7% to 9% and profit margins in the low to mid teens, with valuation framed around P/FFO in the high teens to low twenties over time.
• Flags reasons some investors might be cautious, including a possible overbuild in some regions, high leverage, tenant concentration and the risk that valuation multiples move well ahead of fundamentals.

Both narratives work from the same raw information and arrive at very different fair values. This illustrates how the same data can support contrasting interpretations. You can decide which story feels closer to your own expectations about AI and cloud demand, funding costs and future profitability, then adjust the inputs to build a version that matches your view of Digital Realty Trust, or start fresh with your own Community Narrative using the same tools that underpin these examples.
