CleanSpark, Inc. CLSK used its third-quarter fiscal 2026 earnings call to frame the Sandersville data center lease as the foundation of its shift from bitcoin mining toward diversified digital infrastructure. Management focused on execution, financing and follow-on opportunities across its power portfolio.
The company incurred a loss of $0.40, wider than the Zacks Consensus Estimate for loss of $0.30. Revenues of $138 million also lagged the consensus estimate of $139.4 million.

CLSK Anchors Pivot With Sandersville Lease
CEO and chairman Matt Schultz said that the 20-year Sandersville lease covers nearly 250 megawatts and 175 megawatts of critical IT load. The initial term represents $6.6 billion of contracted revenues.
Schultz said that the triple-net structure places taxes, insurance and maintenance capital expenditure with the tenant, supporting near-100% net operating income conversion and average annual NOI of about $330 million.
Schultz added that the first data hall remains on track for ready-for-service in the fourth quarter of calendar 2027. CleanSpark has ordered and prepaid all long-lead data center items required for that schedule.
CleanSpark Funds Build Without New Equity
President and CFO Gary Vecchiarelli said that Sandersville's expected capital requirement is $1.8-$2.1 billion, based on project costs of $10-$12 million per critical IT megawatt.
Vecchiarelli said that CleanSpark plans to finance the vast majority with project-based debt and is targeting a loan-to-cost above 90%. The anticipated equity portion is already funded, and management does not plan to issue equity or equity-linked instruments for Sandersville.
A Keefe, Bruyette & Woods analyst pressed management on lender appetite. Vecchiarelli said that financing above 90% loan-to-cost has been common in recent transactions and management remains confident in its target.
CLSK Waits on Texas as Exclusivity Holds
Schultz said that up to 885 megawatts across Sealy and Brazoria remain under exclusivity with the Sandersville counterparty. The discussions continue despite the ERCOT review and delay in final Batch 0 determinations.
A Needham analyst asked which Texas capacity still requires approvals. Chief business officer Harry Sudock said that Sealy and the first 300 megawatts at Brazoria received Batch 0 go status but still require final ERCOT determinations.
Schultz identified the Aug. 20 PUCT hearing as the next milestone, while acknowledging uncertainty beyond that meeting. Management said that it continues investing in both sites without changing anticipated energization timelines.
CleanSpark Keeps Bitcoin as Capital Lever
Schultz said that bitcoin mining remains useful because it can monetize power before data centers are completed and bring load online quickly when utilities need it.
Vecchiarelli described the bitcoin treasury as a strategic capital asset. As of June 30, the company had nearly 14,000 bitcoin and approximately $400 million of undrawn bitcoin-backed credit capacity.
A Maxim Group analyst asked whether digital asset management remains a priority. Vecchiarelli said that the company continues selling most production to fund operations, using covered-call strategies to generate cash and retaining the option to deploy bitcoin toward infrastructure opportunities.
CLSK Mining Economics Stay Under Pressure
Vecchiarelli said that fiscal third-quarter revenues rose 1% sequentially even as average revenue per bitcoin mined declined 5% to approximately $72,000. Higher uptime and hash rate offset the lower realized revenues per coin.
The gross margin fell to about 38% from 40% in the fiscal second quarter. Adjusted EBITDA was negative $113 million, although Vecchiarelli said that normalizing for the bitcoin mark-to-market adjustment produced $20 million.
When a Maxim Group analyst asked about weaker future mining economics, Vecchiarelli said that the company is prioritizing capital deployment toward AI data centers while viewing bitcoin mining as the means to support that transition.
CleanSpark's Focus Stays on Powered Land
Management's posture after the fiscal third quarter centered on converting grid-connected power into long-duration data center cash flows while using mining and the bitcoin balance sheet to bridge the development cycle.
Schultz and Sudock also emphasized disciplined site selection and project readiness as CleanSpark evaluates additional infrastructure opportunities across the United States.

Research Chief Names "Single Best Pick to Double"
From thousands of stocks, 5 Zacks experts each have chosen their favorite to skyrocket +100% or more in months to come. From those 5, Director of Research Sheraz Mian hand-picks one to have the most explosive upside of all.
This company targets millennial and Gen Z audiences, generating nearly $1 billion in revenue last quarter alone. A recent pullback makes now an ideal time to jump aboard. Of course, all our elite picks aren’t winners but this one could far surpass earlier Zacks’ Stocks Set to Double like Nano-X Imaging which shot up +129.6% in little more than 9 months.
