Summary

  • CSDC Finance I, a CleanSpark project subsidiary, closed $2.276bn of 7.875% senior secured notes on 25 September. Issued at 98.500% of face, they produced about $2.242bn of gross proceeds before fees—not $2.276bn of cash.
  • The debt clock has begun before the rent clock. Interest is payable from April 2027; initial Sandersville delivery and rent are expected in the fourth quarter of 2027, while full rent for every phase requires a later contractual Final Commencement Date.
  • The $327m initial debt-service reserve, CleanSpark completion guarantee, project collateral and controlled cash waterfall do not prove a finished 175 MW facility. They allocate the risk that construction, power, commissioning and tenant acceptance take place after lenders have funded.

The obligation arrived first

There is a simple way to read the Sandersville transaction: start with what became irreversible on 25 September. CleanSpark’s Form 8-K says its indirect subsidiary CSDC Finance I completed a private offering of $2.276bn of senior secured notes due in 2031. The coupon is 7.875%. Interest is paid on 1 April and 1 October, beginning on 1 April 2027. The notes are no longer an intention subject to market conditions; they are an outstanding claim.

The campus is at a different stage. CleanSpark’s September investor presentation describes 175 MW of contracted IT load, a 20-year base lease and initial delivery and rent commencement expected in the fourth quarter of 2027. The company’s June-quarter filing calls the data-centre strategy early-stage and identifies financing, construction, specialised equipment, approvals and power as live dependencies. It also says the site’s bitcoin mining is expected to be fully decommissioned during fiscal 2028.

Debt and rent can support each other without starting together. Project finance exists precisely because construction consumes capital before the asset earns. But the separation matters. From closing, the project has a fixed financing cost. Until rent commences, that cost cannot be met from the operating stream that justified the borrowing. The legal documents therefore have to decide who supplies cash, who loses flexibility and who gets paid first while the physical asset catches up.

Face value is not cash in the account

The issue was proposed on 17 September at $2.227bn. A day later, CleanSpark priced $2.276bn at 98.500% of principal, and the larger issue closed a week later. The final face amount is $49m above the proposal, but the discount matters: 98.5% of $2.276bn is about $2.24186bn of gross proceeds before underwriting fees and other expenses. That is about $34.14m below the amount the issuer must repay at face, absent amortisation, redemption or repurchase.

The coupon creates another boundary. At the initial face amount, 7.875% means $179.235m of annual cash interest, or $89.6175m every six months before principal changes. The pre-pricing presentation had illustrated $2.227bn of debt at 7.5%, equivalent to $167.025m a year. Final face and coupon therefore add about $12.21m of annual interest to that illustration. This is not a forecast of total debt service: principal amortisation later changes both the payment and the interest base. It is the cleanest measure of what pricing changed.

Proceeds also do three jobs. They fund the remaining cost of Sandersville, reimburse CleanSpark for some prior equity contributions and fund debt-service reserves. A dollar assigned to the reserve is not a dollar available for construction. A dollar reimbursing the parent replaces capital already spent rather than adding a new piece of equipment. The face amount, the gross issue-price proceeds, the net proceeds and the remaining construction budget are four different numbers.

The reserve describes the gap

The indenture sets an initial Debt Service Reserve Required Amount of $327m. Its formula includes scheduled interest on the next three payment dates, the first principal instalment and estimated earnings on deposited funds. During construction, the requirement steps down as interest is paid, subject to a floor. After construction, the initial minimum required amount is $100m, with proportional adjustments if notes are added, redeemed or cancelled.

That reserve is not excess liquidity. It is the document’s acknowledgment that payment dates arrive while the facility is being built. Three initial half-year coupons at the issued face amount would total about $268.9m before any principal instalment. The difference between that arithmetic and $327m should not be reverse-engineered into a promised first amortisation payment: the indenture’s reserve formula includes estimated earnings and future variables. What can be said is narrower and more useful. Lenders required a dedicated pool large enough to carry a substantial construction-period debt-service burden.

The first interest date precedes management’s Q4 2027 initial-rent expectation. The reserve protects that interval. It does not retire the delivery risk that creates it. If construction slips, money in a reserve can meet specified financing payments for a time; it cannot install switchgear, obtain a permit, energise a substation or satisfy a tenant’s commencement conditions.

CleanSpark guarantees completion, not every outcome

The parent’s completion guarantee is the next bridge. The 8-K says CleanSpark must fund the issuer as necessary for timely completion if note proceeds and other available funds, including earlier parent equity, prove insufficient. Cost overruns and funding gaps therefore do not remain solely inside a thin project company during construction. They can call on the parent.

That promise is material, but its perimeter matters. It is a completion guarantee, not a statement that CleanSpark unconditionally guarantees every note payment through 2031. Nor is it a guarantee that all construction, power and acceptance milestones will occur on the current timetable regardless of external constraints. Its economic force is that a project shortfall can become a parent cash requirement before the project earns rent.

The notes also carry first-priority liens on substantially all relevant assets of the issuer and property subsidiary, subject to exclusions, and on the issuer equity held by its direct parent. The project is ring-fenced enough for lenders to trace collateral and cash, but not isolated enough for CleanSpark to walk away from an underfunded build. That combination is the transaction’s central allocation: asset-level security for creditors, completion exposure for the parent.

Meta supports the tenant’s cheque, not the construction schedule

The lease structure adds a separate credit layer. The indenture identifies Anviran LLC as the data-centre tenant and Meta Platforms as guarantor of the tenant’s payment obligations. CleanSpark’s presentation describes a 20-year base term, two five-year tenant extension options, a further 12-month option, a 3% annual rent escalator and about $6.6bn of base-term contract value. It estimates average annual net operating income of roughly $330m and an approximately 100% triple-net NOI margin.

Those figures explain why lenders were willing to finance one facility against one long lease. They do not make the notes Meta debt. Meta’s limited parent guarantee supports Anviran’s lease-payment obligations. It does not substitute for CleanSpark’s construction obligations, and it does not make rent payable before the lease’s commencement conditions are met.

The distinction is especially important because the financing has closed before the underlying rent stream. Tenant credit can be excellent and still be unavailable to pay a project bill today if the contractual obligation has not started. Construction risk sits before credit risk in the sequence. Once rent begins, Meta’s guarantee can strengthen the predictability of the inflow. Until then, reserves, proceeds and CleanSpark’s completion support carry the structure.

Full rent, not a ceremonial ribbon, starts amortisation

The indenture defines Final Commencement Date precisely: the last date on which every applicable phase has satisfied its rent-commencement conditions and the full amount of lease payments for all phases begins to accrue. Initial delivery in Q4 2027 may begin the economic transition, but it is not automatically the same event as full commencement.

Principal is not scheduled to amortise before the first payment date after Final Commencement—unless that date falls within 15 days of a payment date, in which case amortisation starts at the following one. On each subsequent payment date, the instalment is sized so that project debt-service coverage, after giving effect to interest and principal, equals a target of 1.275 to 1.

This is a cash-sweep discipline expressed as a ratio. Once the project earns, debt principal is not left to wait untouched until 2031. If net operating income supports more debt service than interest alone, the formula directs cash toward principal until the target coverage is reached. Stronger operating cash flow can accelerate deleveraging; weaker cash flow leaves less room for principal while preserving the coverage boundary, subject to the rest of the document.

The company’s presentation had illustrated amortisation beginning in March 2028 on a 7.5% coupon. The final indenture uses April and October payment dates and the 7.875% coupon. The presentation remains useful as evidence of management’s pre-pricing model, not as the final payment schedule. Actual commencement timing, NOI and the operative ratio will determine the instalments.

Rent enters a controlled channel

The cash waterfall turns the financing thesis into an order of payment. Project revenues, including rent, flow into a Revenue Account maintained under a springing control agreement for the collateral agent. Cash first pays operating expenses. Second, it pays note debt service due. Third, it replenishes the reserve to the required amount. Only fourth may it be used for other purposes permitted by the indenture.

The order prevents a common analytical mistake. A projected $330m of average annual NOI is not automatically $330m of cash available to CleanSpark shareholders. Project costs, interest, scheduled amortisation and reserve needs stand above discretionary release. Triple-net lease economics can reduce the landlord’s operating-cost burden, but they do not remove the financing waterfall.

The Notes Proceeds Account is similarly constrained. It funds project development, construction and associated costs until depleted. Any remainder can be used more broadly only after Final Commencement and only for permitted purposes. Cash may sit within the consolidated group and still be unavailable for another site. Ring-fencing is not a footnote to the financing; it is what allows the future rent to support the present debt.

Lease termination has a procedure, not a magic refund

The documents also anticipate the central concentration risk: a single project built around one tenant. If the lease or its guarantee terminates, the issuer receives time to secure a qualifying replacement. The ordinary default window is six months. It may extend to twelve months if, among other conditions, a qualified-tenant letter of intent is in place, the reserve is sufficiently funded, operating resources are adequate and specified investments and distributions remain constrained.

If a termination payment greater than $15m is received, the issuer must, after the defined replacement/default window, offer to repurchase notes with the available termination amount at 100% of principal plus accrued interest. This is protection, but it is not a promise that every note is repaid in full. The offer is limited by the termination amount and the amount tendered. Scheduled principal instalments are deferred during the relevant termination period until a qualifying replacement lease or the end of the window.

The mechanism shows where the lenders’ confidence ends. They accept construction and tenant concentration because collateral, reserve, parent support, lease credit and remedies surround the exposure. They do not assume that a terminated lease can be replaced instantly or that a termination payment necessarily equals the debt balance.

The project is financed, not delivered

CleanSpark’s June-quarter 10-Q provides the operating baseline. The company then had one infrastructure lease with a data-centre customer. It expected Sandersville deliveries to begin in Q4 2027 and warned that financing, power, equipment, approvals and construction could affect the timetable. The site was still supporting bitcoin mining, with full decommissioning expected during fiscal 2028. Reported revenue was mining revenue, not rent from the future AI/HPC facility.

The note closing retires one of those conditions: the principal project financing has been raised. It also creates a new fixed claim and makes the remaining conditions more consequential. A delay no longer means only that future rent moves right. It means reserves are consumed, parent support may be called and the distance between interest expense and operating income widens.

That is why “financed” and “finished” must remain separate evidence states. The $2.276bn close is a real achievement and a real obligation. The 175 MW lease is a real contract and a future income source. The conversion from one to the other will be evidenced by physical milestones, commencement notices, controlled rent receipts and principal paydown—not by restating either headline.
