| Data hall readiness (Sandersville) | First data hall ready for service | Jun 2026 | The first data hall remains on track to be ready for service in the fourth quarter of calendar 2027, and we've already ordered and prepaid for all data center long lead items for RFS. | New |
17 of CLEANSPARK, INC.'s 20 targets are still open. See which are on track and which have gone quiet. The 1 above are the free sample; 19 more targets are in the full ledger.
Claimed
- Secured a 20-year triple-net lease for Sandersville campus with a high investment-grade global technology company, representing $6.6 billion in contracted revenue, with potential to scale to $11.6 billion over 30 years.
- Expected average annual Net Operating Income (NOI) of approximately $330 million from the Sandersville lease, with near 100% NOI margin due to triple-net structure.
- Fully funded the equity portion of the Sandersville project, with plans for project-based debt financing exceeding 90% loan-to-cost, avoiding equity dilution.
- Maintained strong liquidity of $917 million as of June 30, including $200 million cash and almost 14,000 Bitcoin, providing "dry powder" for future accretive opportunities.
- Q3 FY26 revenue increased to $138 million, up 1% QoQ, despite a 5% decrease in average revenue per Bitcoin mined.
Qualified
- GAAP net loss for Q3 FY26 was $240 million, primarily driven by unfavorable mark-to-market adjustments on Bitcoin balances of $133 million.
- Gross margin in Q3 FY26 decreased to 38% from 40% in Q2 FY26 due to a modest increase in power prices.
- Adjusted EBITDA was negative $113 million in Q3 FY26, though positive $20 million when normalized for non-cash mark-to-market adjustments.
- ERCOT's Batch 0 determinations for Texas sites are delayed beyond August 7, with a key milestone on August 20, introducing timing uncertainty.
- Austin County adopted a temporary countywide moratorium on AI data centers on July 27, potentially impacting the Sealy site, though management expects a positive resolution.
