CleanSpark just put $1.15 billion of zero-coupon debt on its balance sheet. The deal closed November 13, 2025, and the filing landed the same day.

The structure is aggressive in the way Bitcoin miner capital raises tend to be. No interest. No accretion. A 2032 maturity. And an initial conversion price of approximately $19.16 per share, set at a premium to where the stock was trading when the purchase agreement was signed on November 10.

The Simultaneous Share Repurchase Changes the Net Capital Picture

The gross raise was $1.15 billion. Net proceeds after initial purchaser discounts and expenses came to approximately $1.13 billion. But CleanSpark did not sit on the full amount. The company immediately deployed roughly $460 million to repurchase common shares from investors in the notes. That is a paired transaction: new debt in, existing equity out. The net capital addition to the balance sheet is closer to $670 million, not $1.13 billion, once the buyback is accounted for.

That kind of concurrent repurchase is standard in convertible note deals structured for qualified institutional buyers under Rule 144A. The mechanics reduce dilution overhang from the conversion feature while giving note buyers an offsetting equity position to hedge. For $CLSK shareholders who were not part of the transaction, the immediate effect is a smaller share count and a larger debt load.

Where the Remaining Proceeds Are Headed

The 8-K is specific about intended uses in a way that boilerplate filings often are not. CleanSpark named four categories: expansion of the company's power and land portfolio, development of data center infrastructure, repayment of outstanding Bitcoin-backed line of credit balances, and general corporate purposes. The filing does not allocate dollar amounts across those buckets, and forward-looking statements carry the standard safe-harbor caveat. But the explicit mention of Bitcoin-backed credit repayment is notable. It signals that some portion of the zero-coupon long-dated debt is being used to retire shorter-term, presumably higher-cost, Bitcoin-collateralized borrowing.

That is a liability management move layered inside a growth capital raise. The company is extending duration and eliminating interest expense simultaneously, at the cost of conversion optionality granted to note holders.

The Conversion Terms and Redemption Window

The notes convert at 52.1832 shares per $1,000 principal, equivalent to approximately $19.16 per share. Holders cannot convert freely until August 15, 2031, except upon certain triggering events before that date. CleanSpark cannot redeem the notes before February 20, 2029. After that date, redemption requires the stock to have traded at or above 130% of the conversion price for at least 20 trading days within a 30-consecutive-trading-day window.

The practical effect is a long lock on both sides. Note holders are patient capital with a conversion option deep in the future. CleanSpark has no near-term call right. The company's equity story has to carry the weight of this structure for several years before either side has meaningful optionality.

Filing Signals and Balance Sheet Context

$CLSK's Filing Risk Score sits at 100, and Event Momentum matches it, both reflecting the density of capital markets filings the company has generated around this offering. Those scores measure disclosure intensity, not financial distress. A miner that raises $1.15 billion in a single transaction will generate exactly this kind of filing cluster.

The balance sheet context matters here. CleanSpark disclosed aggregate fair market value of approximately $813.22 million for its Bitcoin holdings as of March 31, 2026, per the May 10, 2026 10-Q, at $68,222 per BTC. That figure postdates the November 2025 offering by roughly four months, which means the Bitcoin position that now sits alongside this new debt load has been marked at a price well above where the conversion feature was set. The relationship between the Bitcoin treasury and the convertible debt structure is the core tension to track going forward.

The Stock Has Recovered Sharply Since the Deal Closed

Price context adds useful framing. $CLSK has gained approximately 28% over the past 30 days and roughly 57% over the past 90 days as of May 20, 2026. The stock sits above its 20-day, 50-day, and 200-day moving averages, and the short-term trend is an uptrend. The 52-week low of $8.00 was set on March 30, 2026, about four months after this offering closed. The stock has more than doubled off that low.

That recovery matters for the conversion math. The initial conversion price of approximately $19.16 is still above current levels, which means the notes remain out of the money on conversion. But the gap has narrowed considerably from where it stood when the stock was near its 52-week low.

The crypto Fear and Greed index sat at 29 at the time of this analysis, classified as fear, while Bitcoin dominance held at 58.1% and 30-day realized Bitcoin volatility ran at approximately 25.4%. A calm volatility regime with a fear-skewed sentiment backdrop is the environment in which $CLSK's conversion optionality is being priced by the market right now.

The next read on this structure comes from the next quarterly filing, which will show whether the Bitcoin-backed credit lines were actually retired and how the power and land expansion spending is tracking against the capital raised here.
