Data center renewal rental rate change measures how rental rates change when existing leases renew under the operator's methodology.

Digital Realty compares the beginning rental rate on renewed agreements with the ending rental rate at expiration and weights the result by net rentable square feet.

Renewal repricing isolates the existing lease base

New-leasing rates can be influenced by new buildings, new markets, large power blocks, or a changing mix of customers.

Renewal rental-rate change instead asks what happens when existing occupied capacity reaches expiration and is repriced.

That makes it an important indicator of embedded mark-to-market in the installed portfolio.

Cash and GAAP renewal spreads differ

Digital Realty reports renewal rental-rate changes on both cash and GAAP bases.

Those percentages are not interchangeable.

Cash renewal spreads focus on contractual cash rents.

GAAP renewal spreads can reflect the accounting treatment of rent over the lease term.

In the second quarter of 2026, Digital Realty reported materially different cash and GAAP renewal-rate changes, illustrating why the basis must be retained.

Mix can dominate the consolidated percentage

Digital Realty reports renewal spreads across product groups including 0-1 megawatt, greater-than-1-megawatt, and other space.

A small number of large hyperscale renewals can move the overall weighted result substantially.

Investors should therefore inspect segment mix rather than reading the consolidated percentage as a universal market-rent index.

Renewal pricing is not bookings growth

A strong renewal spread can improve the economics of the existing portfolio without adding new capacity or customers.

Data Center Annualized Gross Bookings and signed new leases capture a different part of the commercial engine.

Renewal pricing answers the repricing question.

Bookings answer the new-sales question.

Primary-source examples

Data center renewal rental rate change is most useful as an existing-lease repricing measure whose cash-versus-GAAP basis and product mix must remain explicit.

Part of the Data Center Operating Model

Connect billed capacity, recurring rent and interconnection revenue, new bookings, signed-not-commenced backlog, and renewal repricing to understand data-center demand and monetization.

How the model fits together
  • Capacity and recurring monetization: Cabinet utilization shows how much Equinix cabinet capacity is billed. Digital Realty annualized rent and Equinix interconnection revenue are separate recurring-revenue lenses, so they add monetization context without forming a standardized cross-company formula.
  • Bookings, backlog, and repricing: Equinix Annualized Gross Bookings capture near-term recurring revenue expected to start within 90 days, while Digital Realty signed-not-commenced backlog captures future annualized GAAP base rent awaiting lease commencement. Renewal rental-rate change then shows repricing on expiring Digital Realty leases. These measures describe different stages and must not be treated as interchangeable.
