Sizing debt against operating cash

Separate the funding gaps

A cluster can have enough committed capital to buy its equipment and still run short of cash before customers pay. Build a monthly sources-and-uses schedule that separates hardware deposits, delivery payments, installation, fees, operating losses and reserves. Then assign an available funding source to each use. An indicative facility is not cash, and an undrawn commitment may depend on milestones the project has yet to achieve.

American Compute’s cluster-finance guide describes the coordination problem between equity, customer commitments and debt. A funding-readiness test asks: what evidence does each provider require, who supplies it and when must it exist? This highlights circular conditions early, such as a customer requiring an operational cluster while the lender requires a signed customer contract.

Measure coverage after operating costs

Use cash available for debt service, after the operating costs defined in the model, as the coverage numerator. Gross rental revenue divided by loan payments can flatter the project because it leaves power, hosting, maintenance and other costs unpaid. State the convention and reconcile it to the contractual covenant definition before comparing ratios.

Utilisation, realised price and collection timing need separate assumptions. Technical uptime does not mean billable capacity; a signed reservation does not automatically mean an unconditional payment obligation. Model availability credits, ramp-up, termination rights and contract expiry. A flat utilisation assumption hides the period in which cash reserves are most exposed.

Draw to milestones; stress the refinancing need

Delayed draws can align debt deployment with hardware acceptance and reduce interest on amounts not yet borrowed. They can also introduce commitment fees, long-stop dates, eligibility conditions and an obligation to bridge deposits with equity. Compare the complete cash schedule rather than the headline rate. A cheaper facility that arrives too late can create an expensive funding gap.

For an illustrative stress test, move first customer collections back three months, lower realised rental prices and shorten the first contract. Recalculate minimum cash, debt-service coverage and the balance outstanding at renewal. Add junior debt only after those results are visible. Junior capital closes a funding gap but also adds a payment claim; it cannot create operating cash.

Keep benchmarks in their proper place

Calculate break-even utilisation from the project’s costs, realised price, financing and ramp. Published examples depend on their assumptions and cannot establish a market-wide threshold. An SPV also does not by itself establish bankruptcy remoteness or unrestricted contract transfer.
