What is the refinance gap in a data center financing?

A data center is usually paid for with debt, and the debt is repaid from rent. Three dates matter: the year the debt comes due, the year the tenant's lease ends, and the year the power contract ends.

The refinance gap is the year the debt comes due minus the earlier of the lease end and the power contract end. A positive number means the debt is still owed after the contracts that pay it have ended. When that happens, the owner must renew the lease, find a new tenant or refinance the debt on new terms.

A gap is not a default. Many financings are expected to be refinanced, and lenders know it. The gap shows how much of the repayment depends on that refinancing going well, and so how exposed a lender or a fund holding the debt is if a lease is not renewed or credit markets tighten.

What to check

• The year the debt comes due, and whether the date is stated or estimated.
• The year the lease ends, and whether the tenant has renewal options.
• The year the power contract ends, and who pays if the customer leaves early.
