Data Centre REITs
Data Centre REITs
Data centre REITs own and operate data centers—specialized facilities that house computer servers, storage equipment, and networking infrastructure. Companies and cloud providers rent space, power, and cooling to run applications, store data, and deliver digital services. The two largest U.S. data centre REITs are Equinix (EQIX) and Digital Realty (DLR). Data centre REITs are among the newest and fastest-growing REIT sectors, benefiting from secular trends in cloud computing, artificial intelligence, video streaming, and enterprise digital transformation.
Key takeaways
- Data centres are specialized real estate that house servers and computing equipment for cloud providers, tech companies, and enterprises.
- Equinix and Digital Realty are the largest and most diversified global data centre REITs, with extensive geographic and customer diversification.
- Data centre rents are growing faster than traditional real estate due to strong, secular demand for cloud and AI computing.
- Yields are low (2% to 3%) but total returns have been exceptional due to rent growth and capital appreciation.
- Data centre REITs are suitable for growth-oriented investors with long time horizons seeking exposure to cloud and AI infrastructure.
The data centre business model
A data centre REIT owns a building (or multiple buildings) equipped with power distribution, cooling systems, security, and connectivity infrastructure. Customers lease space by the rack, cabinet, or floor. They pay for power consumption, bandwidth, physical space, and associated services. A typical lease might run 3 to 5 years, providing visibility and stickiness.
The business model is straightforward: minimize operating costs (power, cooling, labor, security), maximize occupancy and utilization, and steadily raise rents as demand exceeds supply. Modern data centres are marvels of engineering—they are designed to dissipate enormous amounts of heat, maintain redundant power supplies, and operate with maximum uptime (often 99.99% availability).
Customers range from hyperscale cloud providers (Amazon Web Services, Microsoft Azure, Google Cloud) to traditional enterprises, financial institutions, and smaller technology companies. Hyperscale providers build their own data centres in some cases, but they also rent colocation space from data centre REITs for redundancy, geographic diversification, and specialized services.
Equinix: The global colocation leader
Equinix (EQIX) is the world's largest colocation REIT, with over 250 data centers globally (primarily in the United States, Europe, and Asia-Pacific). EQIX serves hyperscale cloud providers, financial services firms, content delivery networks, and enterprises. Its value proposition is clear: provide world-class data centre facilities in strategic locations with strong power infrastructure, international connectivity, and professional management.
EQIX has grown revenues and earnings at double-digit rates for much of the past decade, far exceeding typical REIT performance. Its stock price has appreciated substantially, delivering strong total returns. EQIX yields only 2% to 3%, but the growth more than compensates. For investors seeking growth exposure to cloud and AI infrastructure, EQIX is a core holding.
EQIX's global diversification is a strength. It has exposure to U.S. hyperscale growth, European cloud adoption, and Asia-Pacific expansion. This geographic spread reduces dependence on any single market or customer.
Digital Realty: Scale and diversification
Digital Realty (DLR) is the second-largest data centre REIT, with hundreds of facilities globally. DLR competes directly with EQIX in colocation services and also owns significant wholesale data centre capacity (large facilities rented in their entirety to hyperscale providers). This dual model—colocation and wholesale—provides diversification.
DLR has also grown rapidly and has a strong competitive position. Its yields and growth rates are similar to EQIX. For investors, DLR provides an alternative exposure to the same secular growth trends with somewhat different asset composition (more wholesale facilities, less pure colocation).
Power and cooling: The critical constraints
Data centres are constrained by power and cooling capacity, not physical space. A modern data centre with 10,000 square feet of raised floor space might support 5 to 10 megawatts of IT load (the amount of electricity used by servers). The challenge is delivering that power cleanly and reliably, and dissipating the resulting heat.
Geographic locations with reliable, affordable power (especially renewable power from hydro or wind) are premium. Northern Virginia, where AWS, Microsoft, and others have built massive clusters, has abundant power and low-cost electricity. Same with Oregon (hydro power), Iceland (geothermal), and other locations. Data centre REITs with access to power-rich regions have competitive advantages.
Cooling accounts for 30% to 50% of a data centre's operating costs. Newer facilities use sophisticated cooling technologies (liquid cooling, hot-aisle containment, free-air cooling) to minimize energy consumption. REITs that invest in efficient cooling systems reduce operating costs and increase profitability.
Cloud growth driving demand
Cloud computing adoption is the primary growth driver for data centres. As companies migrate applications from on-premise servers to cloud platforms (AWS, Azure, Google Cloud), they rent compute capacity from the cloud providers. Cloud providers, in turn, lease data centre space from REITs like EQIX and DLR to expand capacity in new markets.
U.S. cloud spending was roughly $400 billion in 2022 and is expected to exceed $600 billion by 2025. This growth is driving increased demand for data centre capacity globally. Every percentage point of cloud market share that Amazon, Microsoft, or Google gains translates to incremental data centre space demand.
AI and large language models: The new demand frontier
Artificial intelligence, particularly large language models (LLMs) and generative AI, is creating new, intensely power-hungry workloads. Training LLMs like GPT requires enormous compute clusters running for weeks or months. Inference (running the trained model to generate responses) requires sustained, high-power infrastructure. Companies building AI applications need massive data centre capacity.
This AI demand is forecast to accelerate through 2025 and beyond as enterprises deploy AI applications and researchers scale LLMs further. Data centre REITs with available power and space are well-positioned to capture this growth.
Rent growth and pricing power
Data centre rents have grown faster than traditional real estate—typically 5% to 10% annually over the past decade, driven by strong demand and supply constraints. When power-constrained data centre markets have high occupancy (over 90%), landlords raise rents substantially. Customers accept higher rents because moving to another data centre is costly and disruptive.
Going forward, rent growth is expected to remain strong as AI and cloud demand continue. A REIT with available power and space in high-demand markets can raise rents significantly as occupancy tightens.
Capital intensity and debt leverage
Data centres are capital-intensive. Building a world-class facility requires substantial upfront investment in power distribution, cooling, redundancy, and security systems. A typical modern data centre might cost $300 to $500 per square foot to build—much higher than a warehouse or office building.
Because of capital intensity and high up-front costs, data centre REITs typically use substantial leverage (50% to 60% debt-to-capital), betting that rent growth and utilization increases will exceed debt costs. This leverage has worked well during periods of rapid rent growth. If rent growth slows or competition increases, leveraged REITs become vulnerable.
Well-managed REITs like EQIX and DLR have strong balance sheets and investment-grade credit ratings, providing buffer for leverage.
Hyperscale customer concentration and diversification
Data centre REITs have exposure to hyperscale cloud providers (AWS, Azure, Google Cloud, Meta, Apple) that are among their largest customers. This concentration creates dependency risk: if a hyperscale customer builds its own data centres and reduces REIT leasing, the REIT suffers.
However, cloud providers continue to rent from REITs for cost efficiency, geographic diversity, and specialized services. They also prefer colocation flexibility (leasing space as needed) rather than owning all infrastructure. Over time, hyperscale capex has stabilized and colocation remains a cost-efficient option.
REITs like EQIX and DLR maintain customer diversification (no customer exceeds 10% of revenue) while still capturing substantial hyperscale demand. This balance is critical for long-term stability.
Geographic arbitrage and market expansion
Data centre REITs pursue geographic expansion into underserved markets. A facility in a tier-2 city with cheap power but limited existing capacity can achieve premium rents as customers seek to enter that market. EQIX and DLR have both expanded globally, entering markets in Asia, Europe, and other regions where cloud penetration and AI adoption are just beginning.
This international expansion provides growth optionality and diversification beyond the mature U.S. market.
