CleanSpark CLSK Posts $181M Q1 Revenue But Swings to $379M Net Loss

CleanSpark (NASDAQ: CLSK) reported fiscal Q1 2026 revenue of $181.2 million on February 5, an 11.6% year-over-year increase, but the Bitcoin miner swung to a net loss of $378.7 million compared to net income of $246.8 million in the same quarter last year. The stock had already dropped 8.8% to $10.36 ahead of the announcement.

The dramatic earnings reversal stems almost entirely from Bitcoin’s price volatility during the quarter. CleanSpark recorded a $246.8 million loss on fair value of Bitcoin holdings versus a $218.2 million gain in Q1 2025. Add in a $103.6 million loss on Bitcoin collateral, and the company’s crypto treasury became a significant drag rather than a tailwind.

Balance Sheet Tells a Different Story

Strip away the mark-to-market noise, and CleanSpark’s operational picture looks considerably stronger. The company exited December with $458 million in cash—up from just $43 million at the end of September—and holds approximately $1 billion in Bitcoin across current and non-current assets. Total assets reached $3.3 billion with working capital of $1.3 billion.

However, that liquidity came at a cost. Long-term debt ballooned to $1.79 billion from $644.6 million the prior quarter, suggesting CleanSpark tapped debt markets aggressively to fund its expansion plans.

The AI Infrastructure Pivot

CEO Matt Schultz positioned the quarter as a strategic inflection point. “CleanSpark is no longer a single-track business,” CFO Gary Vecchiarelli stated during the earnings call. The company secured up to 890 megawatts of utility-grade power capacity in the Houston region and acquired a 122-acre parcel at its Sandersville site, which it’s developing for AI tenancy.

The strategy mirrors moves by other Bitcoin miners diversifying into high-performance computing. With more than 1.8 gigawatts of power capacity across its portfolio, CleanSpark is betting that scarce utility-grade power will command premium valuations from AI infrastructure buyers.

Operational Costs Rising

Cost of revenues jumped 36% to $95.6 million from $70.3 million, while depreciation and amortization climbed 60% to $106.3 million. These increases reflect CleanSpark’s aggressive fleet expansion but compress margins as mining difficulty continues rising post-halving.

Adjusted EBITDA plunged to negative $295.4 million from positive $321.6 million a year ago, though this metric now includes Bitcoin fair value changes that previously were excluded.

What Traders Should Watch

The earnings miss—$1.61 below consensus estimates according to market data—combined with revenue falling short of expectations likely explains the pre-announcement selling pressure. With CLSK trading at roughly $10.36 and a market cap of $2.93 billion, investors are essentially paying around 3x book value for the stock.

The critical question: Can CleanSpark’s AI infrastructure pivot generate returns before its debt load becomes problematic? The company’s next few quarters will reveal whether the multi-gigawatt power portfolio attracts the AI tenants management is banking on.
