Investor WorkspaceA little clarity for your next decision.
By Jerry Baker
Data center REITs own or manage buildings and systems that support computer servers, networks, and digital services. Their investment results depend on usable power, customer contracts, construction costs, reliable operations, and the price investors pay. Growth in cloud computing or artificial intelligence can create demand, but it does not guarantee rent, profit, or a return on REIT shares.
A data center is more than a warehouse with computers inside. Nareit's sector description includes specialized power, cooling, and security features that help support critical technology. Those systems are central to the real estate's use. [1]
Start by asking what the company owns and what the customer supplies. The answer may include land, buildings, electrical equipment, cooling equipment, and network connections. Servers and related hardware may belong to customers. The contract and asset records should make those lines clear.
Next, identify the service being sold. One business may rent large blocks of capacity to a few customers. Another may provide cabinets and connections to many businesses in a shared location. A third may own buildings through joint ventures or operate in leased space.
I do not assume that two companies have the same risks because both use the data center label. A large campus and a dense network meeting point may serve different needs. The value lies partly in where the property is, what it can support, and who has committed to use it.
Ask for a map of owned, leased, and partly owned properties. A branded facility is not always a wholly owned asset.
Data center reports may use square feet, cabinets, kilowatts, or megawatts. Those measures are not interchangeable. A kilowatt measures power. A kilowatt-hour measures energy used over time. One megawatt equals 1,000 kilowatts.
For a simple example, a 10-megawatt IT load running at that level all year uses 87.6 million kilowatt-hours in a 365-day year. That is 10,000 kilowatts multiplied by 8,760 hours. The facility also needs energy for cooling and other support systems.
Distinguish utility capacity from power available for customer equipment. Then separate installed capacity, leased capacity, and actual usage. An announced future expansion is not the same as a completed building with electricity flowing.
Equinix's June 2026 quarterly filing explains that power limits can leave physical cabinet space unused. It also defines cabinet utilization as billed cabinet space divided by cabinet capacity. That is a different measure from the amount of power a facility can deliver. [5]
When reviewing occupancy, write the denominator beside the number. Otherwise, a seemingly simple comparison can mix rented cabinets, leased power, and occupied floor area.
A property can have land, permits, and a customer agreement yet still depend on future electrical work. I want the power plan broken into steps: supply arrangements, utility studies, equipment, construction, testing, and the date service can begin.
Ask who is responsible for each step and who pays when costs change. A letter expressing interest from a utility is not identical to a completed service connection. A contract can still contain conditions, timing assumptions, or limits.
Build a delay case. Suppose a finished phase is expected to earn $1 million a month once service begins. A six-month power delay shifts $6 million of expected revenue beyond the planned start. That is not automatically a $6 million permanent loss, but financing and carrying costs may continue during the delay.
Review whether the customer must still pay, can postpone its start, or can leave under the contract. Do not treat all signed leases as having the same protections.
I also ask whether several projects depend on one substation, equipment supplier, or grid upgrade. Different street addresses do not create separate risks if one delayed system can hold all of them back.
Power usage effectiveness, or PUE, compares total facility energy with the energy used by IT equipment. DOE's guidance defines it using matching annual energy figures. A lower ratio means less facility overhead energy for that measured IT use; it does not by itself prove a higher investment return. [2]
Apply a hypothetical PUE of 1.3 to the 87.6 million IT kilowatt-hours above. Total facility use would be 113.88 million kilowatt-hours. At an assumed flat energy price of eight cents per kilowatt-hour, the energy portion of the bill would be about $9.11 million.
At a PUE of 1.5, total use would be 131.4 million kilowatt-hours and the same simple energy charge would be about $10.51 million. Actual bills can include demand charges, taxes, and other items. The contract determines which party pays.
Water adds another layer. DOE discusses tradeoffs among cooling methods and distinguishes site water use from energy use. A liquid-cooled system is not automatically free of water demand or maintenance. Ask for the actual design and local supply conditions. [2]
Compare measured results with design targets. A promised future PUE, a brief test, and a full year of operations are different evidence. Load levels and weather also belong beside the ratio.
Cloud services, business computing, and AI can all require data center capacity. The uncertainty is how much, where, when, and in what form. Better chips, different software, changing workloads, and customer spending decisions can alter demand.
Berkeley Lab's current modeling work uses equipment and cooling models to study electricity and water use. Its 2025 update presents a range of future energy-demand scenarios. Those are planning estimates, not signed tenant contracts or forecasts of REIT returns. [3]
I would turn a broad growth thesis into property-level questions. Which customers need this location? What applications will run there? Do they need low delay to nearby users, a dense network of connections, or simply a large amount of power?
Then test an alternative. If one expected use grows more slowly, can the building serve another customer without major spending? A useful location for one workload may not have the right connections or design for another.
The goal is to avoid paying for every optimistic version of the future at once. A project should have a clear base case and enough room to handle a less favorable outcome.
New bookings, backlog, and revenue measure different stages. A signed agreement may produce rent after construction, delivery, or another contract milestone. Annualized rent describes a full-year rate, not necessarily the cash received in the current year.
Digital Realty reported a nine-month weighted-average gap between second-quarter 2026 new lease signings and contractual starts. Its quarter-end signed-but-not-started backlog was $1.9 billion of annualized GAAP base rent at full ownership share, versus $1.4 billion at the company's share. Those figures show both timing and ownership distinctions. [4]
For an original example, a contract with $12 million of annual rent starts October 1. Ignoring other adjustments, three months produce $3 million in that calendar year. Counting the full $12 million as this year's cash would overstate the contribution.
Ask which conditions remain before each major contract starts. Review construction progress, customer delivery duties, free-rent periods, and cancellation rights. A backlog schedule is more useful when it shows those dependencies.
Also check whether the reported amount is cash rent or an accounting measure. Growth in one measure may arrive at a different time from cash available to pay bills.
A recognizable customer name can be helpful, but the legal tenant may be a subsidiary. Ask who signs, whether a parent guarantees the obligation, and what that guarantee covers.
Review the lease term, scheduled increases, renewal options, early exit rights, and rights to expand. An option to rent more space is not the same as a binding obligation to pay for it.
For a concentration exercise, suppose one customer group provides 30% of rent. If one-third of that group's rent expires in the next two years, 10% of total rent faces that renewal event. That does not predict a loss. It identifies an exposure to investigate.
Compare credit risk with design risk. A strong customer might pay throughout its lease and still leave a specialized building expensive to reuse when the term ends. Review both the promise to pay and the cost of replacing the customer.
Ask whether several tenants depend on the same end market. Ten legal entities may all be funding similar businesses. A varied customer list does not automatically mean independent sources of demand.
Contracts may bill power separately, include an allowance, or use another cost-sharing formula. Understand the arrangement before treating higher revenue as better economics.
Imagine rent and service fees of $10 million, plus $5 million of reimbursed electricity costs. Revenue totals $15 million. If electricity costs rise to $7 million and reimbursement rises equally, revenue becomes $17 million, but the added $2 million contributes no extra profit in this simplified example.
Timing matters, too. If the owner pays the utility first and collects from the tenant later, it may need working capital. A reimbursement clause does not remove every cash-flow risk.
Review caps, exclusions, billing disputes, and credit losses. Ask how the company reports pass-through revenue and expenses. Compare margins using the same definition from period to period.
The same care applies to rent increases. A large increase on a small group of renewals does not equal the same increase across the entire portfolio. I want the share of rent that actually resets during the period and the cash effect after any related spending.
A data center can require backup power, cooling, network access, physical security, and skilled staff. Review how those systems work together and what happens when one fails.
Equinix's June 2026 filing identifies service commitments, possible customer claims, and limits to insurance protection. It also notes reliance on third parties for power and parts of its infrastructure. Those are disclosed company risks, not evidence that every outage produces the same liability. [5]
I would ask for the testing schedule, repair history, backup fuel plan, and staffing coverage. A redundancy label is a starting point. The practical issue is whether the system has been built, maintained, and tested as described.
For a hypothetical contract, a service failure triggers credits equal to 20% of a $500,000 monthly fee. That is $100,000 before repair costs or any other claims. The actual contract may use a different formula, cap, or remedy.
Cybersecurity duties also need a clear boundary. A landlord's physical security controls do not automatically protect all software or customer data. Ask which systems the operator controls and which remain the customer's responsibility.
A project budget can include building work, electrical gear, cooling systems, network equipment, testing, and financing. A future customer may need a design different from today's tenant.
I would separate three kinds of spending: keeping current service reliable, upgrading a building for changing demand, and building new capacity. Calling every project growth spending can hide the cost of keeping existing revenue.
Use a hypothetical $200 million development expected to generate $18 million of annual property NOI when stable. The projected yield on cost is 9%. If total cost rises to $230 million and NOI reaches $16 million, it falls to about 7.0%.
That measure is not the shareholder return. It excludes the wait to reach stable operations, financing effects, company costs, and the final value. Ask how long the project must operate before it recovers the cash invested.
For an existing facility, examine whether upgrades can occur while customers remain online. A plan that assumes both uninterrupted revenue and a major system replacement deserves detailed technical review.
Joint ventures can share large capital needs. They also create another layer between the property and the REIT shareholder. Read ownership, funding duties, control rights, guarantees, and the order in which cash is paid.
Suppose a venture owns a $500 million project with $300 million of debt. Its equity is $200 million. A REIT owning 40% of that equity has an $80 million share before other terms. It does not own $200 million of unlevered property merely because 40% of the gross asset value equals that amount.
If the venture needs $20 million more and the members must fund it in proportion to ownership, the REIT's share is $8 million. Agreements can allocate funding differently, so use the actual terms.
Separate base ownership returns from development fees or incentive payments. A large fee earned when a milestone is met may be valid income but may not repeat each quarter.
I would reconcile all reported capacities and revenues to the company's economic share. Showing a project's full size can explain its scale. It should not imply that all of its cash belongs to one investor.
Large projects can use cash for years before producing rent. Compare the construction schedule with debt maturities, committed funding, and expected lease starts. The OCC's refinancing guidance highlights how rates, values, and repayment gaps can change financing needs. [7]
In an original stress test, $100 million of debt refinances at a rate two percentage points higher. Annual interest rises by $2 million, before fees and principal changes. If the next project also needs $15 million of equity, those are separate demands on cash.
FFO adds back specified real estate accounting expenses and makes other defined adjustments. It can help compare results, but it does not replace a schedule of cash spending. Read the company's additional adjusted measures and their reconciliations carefully. [6]
Suppose property cash income is $50 million. After $12 million of interest, $5 million of company costs, and $8 million of required capital work, $25 million remains before taxes, principal, new development, and other obligations. That is a more useful starting point for a distribution review than gross revenue.
Review per-share results. A bigger development pipeline can help the company while new shares spread that benefit across more owners. Growth should be measured against the capital required to achieve it.
Completion is not one event. A construction team may finish its work before the customer accepts the space. Equipment testing, customer installation, and billing can follow on different dates. I would put those dates on one page, with a person responsible for confirming each step.
Consider a project that needs three months between construction completion and paid service. If it uses $200,000 a month for interest, staff, and support costs during that period, the handover requires $600,000 of cash. That amount belongs in the funding plan even if the building is technically complete.
Ask what happens if testing finds a problem. Who fixes it? Can the lender release the remaining funds? Does the customer owe anything before acceptance? These are contract questions, so the answers should come from signed documents and technical reports.
Finally, separate a project reserve from cash needed elsewhere in the company. A dollar already committed to a future build cannot also pay a dividend without another source of funds.
Demand can be strong while the purchase price already assumes years of success. Test the valuation using slower leasing, higher costs, and a lower final sale value. An investment needs room for ordinary mistakes, not only extreme disasters.
As a simple share-price example, assume sustainable annual cash earnings of $5 per share. Paying $100 equals 20 times that amount. Paying $150 equals 30 times the same amount. The higher price needs additional support; the property type alone does not supply it.
Also match liquidity with your needs. Listed shares can change sharply in price. Nontraded and private REITs can limit sales and repurchases. The SEC's investor guidance explains why the structure and offering terms matter alongside the properties. [8]
For exchange planning, ordinary REIT shares are not direct Section 1031 replacement real property. A company owning real estate does not make its stock qualify for that treatment. A different transaction structure requires separate tax analysis. [9]
My review ends with a clear chain: funded construction, usable power, enforceable customer payments, necessary reinvestment, and cash per share. Each link needs evidence.
No. You buy an interest in the REIT. Its customers may use facilities for AI, cloud services, or other computing. The REIT's return depends on its contracts, costs, financing, and share price, not just the popularity of one technology.
Electrical or cooling capacity can limit how much customer equipment a building can support. Available floor space does not prove that more usable power is available. Check the specific capacity measure and the cost of any upgrade.
PUE compares total facility energy with IT equipment energy over the measured period. It helps explain overhead energy use. It does not measure water use, total profit, service reliability, or the price paid for the property. [2]
No. Read the contract conditions, start dates, construction duties, and customer credit. Annualized backlog is not the same as rent collected this year. Delays or other changes can affect when the expected revenue begins.
That depends on the agreement. Review billing formulas, timing, allowances, caps, and exclusions. Even reimbursed costs can create working-capital needs or collection risk. Compare revenue and expenses on a consistent basis.
A reported project may be larger than the REIT's own stake. The company can have a share of income, funding duties, or guarantees that differs from the project's headline size. Read the actual ownership and cash-distribution terms.
Ordinary REIT shares do not qualify as direct Section 1031 replacement real property. Consult your qualified intermediary and tax advisor before using exchange funds for any proposed investment structure. [9]
