CleanSpark closes $2.276B Sandersville debt, funding AI data-center buildout

CleanSpark is transitioning from a primarily bitcoin-mining operator into an energy-backed data-center developer, with Sandersville as its first major contracted AI/HPC project. The 175 MW campus is under a long-term lease to a high-investment-grade technology tenant, with initial delivery targeted for Q4 2027 and the broader platform built around roughly 1.8 GW of controlled power.

The financing milestone is real, but not a surprise. CSDC Finance completed the previously announced offering, selling $2.276 billion of senior secured notes due 2031. The September 18 pricing announcement had already disclosed the size, 7.875% coupon, 98.5% issue price, and expected September 25 closing, so this filing mainly converts an anticipated funding plan into completed financing rather than resetting expectations.

It removes Sandersville’s immediate funding question, but does not remove execution risk. Proceeds are intended to finance the remaining facility cost, reimburse prior equity contributions, and fund debt-service reserves. That gives the project a dedicated capital stack and supports the company’s move into contracted compute infrastructure, but the notes are secured against the project structure and impose restrictions on additional debt, asset sales, distributions, liens, and unrelated operations.

The buried obligation is CleanSpark’s completion backstop. CleanSpark will fund the issuer if note proceeds and available project funds are insufficient to finish Sandersville. In plain English, the financing is project-level, but construction shortfalls can still reach the parent company; that makes delivery on budget and on schedule the next substantive test.

Bottom line: This filing confirms the expected financing needed to build Sandersville and advances CleanSpark’s data-center transition, but it is confirmation—not a fresh upside surprise—and leaves the company exposed to construction and completion costs.
