CleanSpark (CLSK), What Is Behind The Fresh Attention On The Stock?

Simply Wall St · 1d ago

CleanSpark (CLSK) just put fresh production numbers on the table, reporting 529 bitcoin mined in September and 5,432 for the year to September 30, 2026, giving investors new data to weigh.

CleanSpark’s recent production update lands after a choppy stretch for the stock, with the share price down 20.97% over the past month and 9.13% year to date. The 1 year total shareholder return has fallen 45.57%, but the 3 year total shareholder return remains very strong, suggesting that long term holders may still be sitting on sizeable gains even as near term momentum has cooled.

The question now is blunt: Are recent losses in CleanSpark mainly a verdict on the bitcoin mining business, or a swing in sentiment that has pushed the valuation too far?

Most Popular Narrative: 56% Undervalued

Against the last close at $10.50, the most followed narrative for CleanSpark points to a fair value of $23.81, which frames the recent share price weakness in a very different light.

CleanSpark's fully self-operated, scalable, and power-efficient infrastructure enables it to mine Bitcoin at a significantly lower cost than the market price, with further capacity expansion (additional 10 exahash and over 200 megawatts of contracted power ready for rapid deployment) poised to drive sustained increases in Bitcoin production, improving revenue and supporting higher net margins.

See why 129 investors see CleanSpark as 56% undervalued.

This widely tracked narrative applies a discount rate of 10.08% and arrives at a fair value estimate of $23.81 per share, compared with the current market capitalization of about $2.73b and last close of $10.50. That gap suggests the market price is assigning a steep penalty to CleanSpark's reliance on Bitcoin mining, while the narrative focuses on contracted power, scale, and efficiency as potential offsets to sector risk.

At the same time, the narrative does not gloss over the pressure points. CleanSpark reported annual revenue of $679.25 million alongside a net loss of $1.03b, and the firm is forecast to remain unprofitable over the next 3 years with less than one year of cash runway. Heavy capex needs, exposure to Bitcoin pricing, and higher risk funding all sit in tension with the idea of a higher future earnings multiple.

For anyone weighing that 56% discount, the key judgement call is whether long duration power access, infrastructure build out and treasury management can eventually overcome those balance sheet and profitability constraints.

Result: Fair Value of $23.81 (UNDERVALUED)

Still, the whole CleanSpark story leans heavily on Bitcoin pricing and energy costs. A weaker crypto cycle or higher power bills could quickly undercut that undervalued thesis.

Another View: What Multiples Say About CleanSpark

While the popular narrative pegs CleanSpark at a fair value of $23.81, the simple P/S yardstick paints a tougher picture. The stock trades on roughly 4x sales, which is similar to the broader US Software group at 4x, yet above a fair ratio of 2.3x that regression work points to as a level the market could move toward. Compared with peers on about 5.9x, that mix of in line sector pricing, cheaper peer positioning, and a higher fair ratio signal leaves you weighing whether this is a valuation gap that slowly closes or a sign that expectations still sit a little hot for a loss making miner.
