Another Day, Another Data Center Company

Today, I’m digging into Digital Realty (DLR).

Yesterday we looked at Equinix, which is the more network-dense, interconnection-heavy player in the data center world. Digital Realty is different. They lean more into large-scale, power-dense facilities for hyperscalers and enterprises. Think of Equinix as “premium connectivity hubs” and Digital Realty as “global powered campuses.”

Before I started this research, I had no idea what network-dense or interconnection-heavy meant. Here is an overview of what it means.

1. Lots of cross-connects

These are physical fiber cables that connect one customer’s equipment directly to another customer’s equipment.

• AWS to a bank

• A trading firm to an exchange

• A SaaS platform to multiple ISPs

• A content delivery network to dozens of network carriers

Equinix has hundreds of thousands of these. Digital Realty has plenty too, but not as many per site.

2. Dense ecosystem hubs

Interconnection-heavy data centers are meeting points. They are where:

• ISPs exchange traffic

• Enterprises directly connect to their vendors

• AI companies link up with storage or training clusters

This creates a true “network effect.” The more people connect inside the building, the more valuable that building becomes.

Here are a few more things that stood out in this comparison:

• As mentioned above, Digital Realty’s revenue is almost entirely recurring rent, while Equinix has a bigger mix of interconnection and higher touch services.

• Gross margins at Digital Realty come in higher than Equinix, but the flip side is tougher: their CapEx burden is heavier relative to operating cash flow.

• Digital Realty depends more on big hyperscale customers, which can create concentration risk.

• Both companies benefit from AI infrastructure demand, but Digital Realty’s expansion requires more ongoing capital than Equinix’s model.

One negative for both companies is just simply how capital-intensive they are. It works as long as capital markets cooperate and leasing stays strong, but there’s not much room for error.

The biggest takeaway from both of these reports, in my opinion, from an entrepreneur's point of view, is that they provide an opportunity to look at two businesses that appear very similar from the outside. But when you dig deeper, you can learn from the differences of each one in more detail.

Peeling back the onion on similar and even different industries can add a lot of value to how you think about your business and/or career.

With that, I'll see you tomorrow!

TL;DR

• Digital Realty is one of the largest data center REITs in the world, providing space, power, and connectivity to enterprises, cloud platforms, and AI infrastructure operators.

• Nearly all revenue comes from long term rental contracts, giving them highly predictable recurring revenue.

• Their scale, capital access, and global footprint help them compete, but their margins depend heavily on constant capex.

• Check out the finance section to see how they stack up to Equinix (yesterday's report). That's one of the main takeaways from this report. Use it as an opportunity to compare the financials of two businesses that play in the same market, albeit with slightly different strategies.

The 30,000-Foot View

• What it does: Owns and operates more than 300 data centers across 50 plus metros globally and leases powered space and interconnection services.

• Business model: Build or acquire data centers, lease capacity on multi year contracts, and develop interconnection ecosystems to deepen customer lock in.

• Revenue mix:

  • Rental and services: 98.7%

  • Fee and other income: 1.3%

• Key stats:

  • Market cap: $55B

  • TTM revenue: $5.91B

  • Gross margin: 55%

  • TTM operating income: $0.87B

  • Employees: just under 4,000

  • Category: data center REIT specializing in wholesale and colocation

Company History

• 2004: Digital Realty forms and completes its IPO, raising $240M with a small portfolio.

• 2005 to 2010: Expansion in major US metros and initial European growth.

• 2015: Acquires Telx to expand into interconnection and colocation.

• 2017: Acquires DuPont Fabros, strengthening its hyperscale footprint.

• 2019 to 2020: Completes $8.4B acquisition of Interxion, creating a dominant EMEA platform.

• 2020s: Launches PlatformDIGITAL to reposition itself as a global interconnection platform.

• 2022: Begins selling non core assets and unifies brands across regions.

• 2023 to 2025: Heavy AI driven leasing, higher renewable energy adoption, and increased development.

• 2024 to 2025: Faces SEC cybersecurity investigation and deals with an operational incident in Singapore.

Show Me the Money

Stand Out Financial Features (let's compare to Equinix (EQIX), from yesterday's report)

• DLR's gross margins have been 4-8% higher than EQIX. This is due to DLR's primary business of leasing out the whole "powered shell", whereas EQIX often leases interconnection, managed services, colocation cabinets, cross-connects and network-dense facilities (which often have a higher variable cost).

• DLR has even more capital intensity than EQIX. Looking at 2024 CapEx/operating cash flow, DLR was at ~125% while EQIX was at ~90%.

• There are many things that could impact the metrics shown above. A company could have different levels of depreciation flowing through their operating profit, or they could have more growth vs. maintenance CapEx. But at the end of the day, both of these companies are spending a tremendous amount of money with impressive, but far from NVIDIA-like growth. And that's okay, because they are different businesses. But when growth stops, it'll be interesting to see if these assets support free cash flow delivered to shareholders.

The N.O.O.B. Nine — Competitive Powers

The Nerd Out on Business Nine is made up of Hamliton Helmer's famous "7 Powers" of competitive advantage (Scale Economies, Network Economies, Counter-Positioning, Switching Costs, Branding, Cornered Resource, and Process Power) combined with two of my own (Data Flywheel and Distribution Advantage).

Average Score: 3.1/5 - Digital Realty has a solid moat built around scale and operational expertise, but it is not unbreakable.
