CleanSpark shares jumped 4.73% on September 17, closing near $13.40. The catalyst: a plan to raise $2.227 billion through senior secured notes to fund its Sandersville data center campus in Georgia.
The notes come out of CleanSpark’s subsidiary, CSDC Finance I LLC, via private placement. They mature in 2031. CSRE Properties Sandersville LLC will guarantee them, and the debt gets secured by a first-priority lien on the assets of both the issuer and the property company — meaning the Sandersville assets themselves sit as collateral. Proceeds go toward completing the facility, reimbursing prior equity investments, and setting up debt-service reserve accounts. No conversion into CleanSpark stock. So shareholders don’t face direct dilution, which is pretty much the best-case scenario for a raise this size. But the debt load is real, and interest rates, issue prices, and closing dates weren’t fully disclosed in the announcement.
Not exactly a clean picture.
Sandersville: The Lease That Started This
Back in July, CleanSpark announced a 20-year lease with a global tech firm for the Sandersville site. If extended, that deal could generate up to $11.6 billion. The company hasn’t confirmed reports naming Meta as the tenant, and it probably won’t until it has to. Initial capacity at the site is expected by Q4 2027, though the financing itself is still contingent on market conditions — there’s no guarantee the deal closes under the terms proposed. If funds fall short, CleanSpark said it will provide a completion guarantee to cover whatever’s left.
The Sandersville land came from Mawson Infrastructure Group, acquired back in October 2022. It already carries significant mining infrastructure, which gives CleanSpark a head start on buildout. The facility is planned for 230 megawatts total, with 175 megawatts dedicated to high-performance computing — a clear signal the company wants to serve AI workloads, not just Bitcoin miners.
That’s a big pivot. Or at least the beginning of one.
Bitcoin Numbers Behind the Headlines
CleanSpark mined 593 BTC in August alone, bringing its 2026 total to 4,903 BTC by the end of that month. The company’s treasury sat at 13,703 BTC as of that same period, though it saw a slight decline — the company was selling into spot markets and running call-option contracts as part of how it manages its crypto holdings.
Fiscal Q3 revenue came in at $198.6 million, up sharply from $104.1 million the year before. But the company posted a net loss of $236.2 million, mostly because of swings in the fair value of its Bitcoin holdings. That’s basically how Bitcoin mining financials work right now — revenue can look strong while paper losses from treasury valuation drag the bottom line. As of June 30, CleanSpark held $933.3 million in cash and Bitcoin combined. Total debt before the new notes offering was already sitting at $1.8 billion.
So add $2.227 billion on top of that, and you’re looking at a company carrying a serious debt stack while betting on a long-term infrastructure play.
On September 17, Bitcoin was trading near $76,300, having bounced back from a dip toward $75,000. Resistance levels were sitting around $77,000 and $78,000, with daily momentum still under pressure. That kind of price environment makes the treasury math tricky — CleanSpark’s Bitcoin holdings are worth a lot more at $80,000 than at $70,000, and the company knows it.
The broader Bitcoin mining sector has been dealing with compressed margins since the last halving. Power costs stay fixed. Block rewards dropped. Miners that diversified into data center hosting or high-performance compute have generally held up better than pure-play miners. CleanSpark seems to be reading that playbook and running with it, hard.
The subsidiary structure it’s using for the Sandersville financing is worth noting too. By isolating the debt inside CSDC Finance I LLC and securing it against project-specific assets, CleanSpark keeps the risk somewhat ring-fenced from the parent company’s broader balance sheet. It’s a fairly standard project finance approach, but it matters when the numbers are this large.
Whether the notes close on the proposed terms is still unclear. Market conditions can shift fast, and a deal this size needs everything to line up. CleanSpark’s completion guarantee backstops the project if financing falls short — but that guarantee itself adds contingent liability to the picture.
The company mined 4,903 BTC through August 2026 and held $933.3 million in liquid assets as of June 30.

Why It Matters
This significant capital raise reflects CleanSpark's aggressive strategy to expand its operational footprint in the rapidly evolving cryptocurrency mining sector, positioning the company to leverage the anticipated growth in demand for blockchain technology. However, the reliance on substantial debt also underscores the inherent risks associated with volatile market conditions and regulatory uncertainties, particularly in the crypto space, which could impact the company's financial stability and asset valuation in the long term.
