Digital Realty (DLR) Has a Backlog and Interconnection Story the REIT Label Misses

Why Digital Realty is more than a rate-sensitive REIT

Digital Realty (DLR) is often sorted into the generic REIT bucket, which can make the stock trade like a plain interest-rate instrument. That framing is too shallow for what the company actually owns. Digital Realty is a global data-center, colocation, and interconnection platform serving customers whose applications are central to daily business operations. The relevant debate is not just cap rates or Treasury yields. It is whether Digital Realty can keep turning network density, power availability, and customer relationships into durable leasing demand.

That matters because the economics of a data-center landlord are different from those of a conventional office or retail REIT. Winning with hyperscale and enterprise customers requires capital, technical capability, and often interconnection depth that smaller peers cannot easily match. Once customers are embedded, the cost of moving can be meaningful. That creates a different type of stickiness than the market sometimes gives DLR credit for.

What the latest results say about Digital Realty’s platform

The first-quarter 2026 update offered a good snapshot of that platform in action. Digital Realty reported quarter leasing bookings of $423 million, including $98 million from the 0-1 megawatt-plus interconnection category. Total backlog reached $1.8 billion of annualized GAAP base rent at 100% share at quarter-end, or $1.0 billion at Digital Realty’s share. The company also reported rental rate increases on renewal leases of 5.0% on a cash basis in the quarter.

Those leasing figures help explain why management raised its 2026 Core FFO per share outlook to $8.00 to $8.10 and its constant-currency Core FFO per share outlook to $7.95 to $8.05. Revenue in the first quarter was $1.6 billion, in line with the previous quarter and up 16% from a year earlier.

Scale still matters here. As of March 31, 2026, Digital Realty’s portfolio included 309 data centers, including 89 held through unconsolidated entities, with roughly 3.0 gigawatts of IT load capacity across the platform. The Q1 release and annual materials make clear that the company is not simply monetizing generic square footage. It is building a global footprint around connectivity, colocation, and customer workload density.

Why backlog, interconnection, and leverage matter

The backlog is arguably the most important number in the story. Annualized base-rent backlog of $1.8 billion means there is already a large amount of contracted demand waiting to move through into recognized revenue over time. That makes DLR less dependent on constantly finding the next incremental lease just to stand still.

Interconnection adds another layer of quality. The $98 million contribution from the smaller-megawatt interconnection category is notable because interconnection and colocation relationships are often stickier than large wholesale leases alone. They can create ecosystem effects inside the platform, making Digital Realty’s campuses more valuable as more customers and workloads cluster there.

Balance-sheet direction also matters. Digital Realty reported net debt to adjusted EBITDA of 4.7x in the first quarter, down from 5.1x in the comparable prior-year quarter cadence shown in its materials. For a capital-intensive platform, that improvement is important. It suggests the company is still funding growth while keeping leverage pointed the right way, which gives more room to pursue demand tied to cloud, enterprise, and AI-related infrastructure buildouts.

What investors should watch next

The main thing to watch is conversion: can Digital Realty keep turning backlog and bookings into sustained Core FFO growth without stretching the balance sheet? Demand signals look healthy today, but this is still a business where execution depends on development timing, power availability, customer fit, and financing discipline.

Investors should also watch the mix of leasing activity. If interconnection and colocation remain a meaningful contributor, the platform thesis gets stronger because those workloads usually support better stickiness and deeper customer ties. Renewal spreads are worth monitoring too. A 5.0% cash rent increase on renewals is solid evidence that existing assets still have pricing power.

The broader point is that Digital Realty should not be reduced to a rate-sensitive REIT trade. It has a global installed base, a meaningful leasing backlog, a growing interconnection footprint, and a leverage profile that is improving rather than deteriorating. If those pieces hold, DLR looks more like infrastructure with embedded demand than just another landlord reacting to bond-market moves.

Key Signals for Investors

Digital Realty’s $1.8 billion annualized GAAP base-rent backlog is the clearest sign that future revenue already has meaningful contractual support.
The $98 million interconnection-related piece of quarterly bookings suggests leasing quality is not limited to large wholesale capacity deals.
Net debt to adjusted EBITDA of 4.7x shows the platform is still growing while leverage trends are moving in the right direction.
