Summary CleanSpark remains a Strong Buy despite recent stock volatility driven by Bitcoin price swings. CLSK trades at an 11.63x forward P/E (GAAP), a 63% discount to peers, highlighting significant undervaluation. The company's AI/HPC diversification is a long-term pivot, enhancing its strategic appeal beyond pure Bitcoin mining. With a $43,000 margin cost per Bitcoin, CLSK is well-positioned to weather potential crypto downturns. Since my previous coverage on CleanSpark ( CLSK ), the stock experienced a sharp downswing. Although weak AI sentiment clouds the AI/HPC pivot, in my opinion, the poor stock price action was mainly driven by Bitcoin volatility. Quite frankly, it does make sense, as 100% of its revenue comes from mining operations. Unless the company signs early contracts with pre-funding, it will take time for CleanSpark to expand its AI capabilities, so I don't expect revenue from the pivot any time soon. Now, has anything changed in the bigger picture? I don't think so. I am holding the stock, and I am not nervous despite a sharp correction. I believe that at the current price tag, it remains heavily discounted. CLSK trades at 11.63 forward P/E (GAAP) , a 63% discount versus peers at 31.23x. The diversification into AI/HPC is a long-term pivot that makes CleanSpark a more compelling play, and with a roughly $43,000 margin cost per Bitcoin , it seems to be well-positioned to withstand another crypto winter if needed. I reiterate a Strong Buy rating. Zero Convertible Enables AI and Mining Infrastructure Funding I love that management stands by its initial plan to not dilute shareholders through ATM offerings. Both mining and AI HPC operations are capital-intensive, and although debt-related funding remains through convertibles, that doesn't weigh on investors' shoulders in the meantime. CLSK closed approximately $1.15 billion convertible at 0% coupon to mature in 2032 as an alternative to raising cash through an ATM. What I also love about the recent announcement is that management stated that while funds will also be used for infrastructure opportunities, CleanSpark repurchased nearly 11% of the total outstanding common stock, reaching $460 million in returned value to shareholders. Quite honestly, that's the opposite of dilution, and to me it raises confidence in management's decisions. This may help EPS growth, too. CLSK: The Company Aim To Lead Energy And Infrastructure Compute (CleanSpark Investor Relations) The legacy miner's ambitions are costly. That's why I like the company's decision to use convertibles to scale, rather than dilute its current shareholders. Especially as there's a significant demand for funding at 0% coupon. It expects to revolutionize into an energy and infrastructure compute leader . I love this. The global AI data center market is anticipated to surge 26.8% CAGR over the next 6 years and reach $93.6 billion in market size by 2032. Now, that's already a significant market, about $18 billion, but it remains in its early stage. CleanSpark offers exposure to this high-growth market from its first innings while also maintaining focus on Bitcoin mining operations. Such peers as IREN ( IREN ) have decided to completely pivot to AI HPC . Now, while the market has rewarded IREN with a massive upside in the short term, logically, it has transferred dependency from Bitcoin volatility to the AI space that is also tied to multiple uncertainties. I am not a fan of this, and quite frankly, I am happy with CLSK's decision to diversify but not shift focus completely. What's next? CleanSpark chose Texas for its AI HPC expansion, acquiring a site and 285 MW power supply agreements . That's a significant step for scaling into the next-gen AI and cloud capabilities. Business transformation unlocks new opportunities for CLSK to tap into a high-growth market. To me, that's an appealing shift. What I also think the market discounts is the company's know-how on how to maintain high-performance computing and sustain the uptick. I believe it will leverage knowledge and experience from mining operations to AI HPC pivot, making it a compelling service provider. Moderately Leveraged Balance Sheet, but Fundamentals Remain Intact Yes, the AI HPC pioneer has a moderately leveraged capital structure that I don't love, but quite frankly, it doesn't make me too concerned. CLSK: Capital Structure (Seeking Alpha) CleanSpark has about $826 million in total obligations . It also has nearly $43 million in cash, but that barely offsets the leverage. Now, why doesn't it make me too concerned? If we have a look at the interest expenses over the past 12 months, CLSK paid $11.3 million to service its debt . That's insignificant. It accounts for about a 1.3% annual interest rate versus total obligations, and quite frankly, that's below the current inflation. On top of that, CLSK benefited from high-yield accounts and generated $4.1 million in interest and investment income, offsetting the interest expense over the past year. So, it actually experienced $7.1 million in net interest expense, or less than 1% versus total obligations. I'd also want to flag that while a dovish Fed could boost sentiment for risk assets, CLSK doesn't really need interest rates to drop significantly. The current debt is tied to low interest rates, which leaves financial flexibility for management. CLSK: FY2025 Performance (CleanSpark Investor Relations) I think we all could agree that FY2025 was a breakthrough performance year for CleanSpark, supported by favorable Bitcoin price action. Now, it has achieved $766 million in FY2025 revenue , which represents a 102% increase on a year-over-year basis. For the bottom line, it was a turnaround year too, posting nearly $365 million in net income, a substantial difference from $146 million in net loss last year. CleanSpark reached 50 EH/s for mining operations and managed to mine 7,873 coins over the FY2025. What I mostly love about the performance is it managed to maintain low-cost operations while significantly increasing EH/s. As I stated previously in the article, the marginal cost per Bitcoin was roughly $43,000. That's nearly 107% above the current BTCUSD price of roughly $89,000 . This supports my bullish stance, as Bitcoin could drop further, and CleanSpark would still mine profitably. Sure, we could argue that the outlook would deteriorate if BTCUSD dropped significantly. I'd like to emphasize a few things here. Firstly, if we assume Bitcoin dropped to the 200-week moving average of nearly $57,000 , which would technically mean a crypto winter, CLSK should be able to mine at approximately 33% profit versus the marginal cost. This indicates fundamental strength, low-cost power contracts, and significant execution, making it a compelling play. Secondly, sure, it would also take a hit on its Bitcoin holdings. It held 13,054 BTC at the end of November, but even if the BTC were to drop to $57,000, that's roughly $744 million in liquid assets at that price tag. CLSK would be able to cover its obligations to a large extent. Lastly, CLSK produced 587 coins in November alone, and while it reflected a 4% drop in BTC produced, the HODL holdings increased by 21 coins. In my opinion, that's due to network difficulty, because hashrate actually increased from 46.6 EH/s to 47.4 EH/s, indicating great execution, but natural fluctuation due to business origin. Quite frankly, in addition to the last argument, the fact that it has increased Bitcoin holdings while production was down on a month-over-month basis implies that management has the financial capabilities to achieve expansion goals without an urgent need for additional funding. That's why I think that fundamentals remain intact and the bigger picture is bullish. Undervalued Versus Peers CleanSpark trades at a compelling valuation. Versus the fiscal FY2026 estimate at 13x , while the 24-month earnings multiple reaches about 10x. CLSK: Trading At Compelling Valuation (Seeking Alpha) For instance, IREN trades at roughly 40x earnings multiple versus fiscal FY2026, while Cipher Mining ( CIFR ) trades at 48x . That's at least 3x undervaluation versus peers that have pivoted to AI HPC. We could also compare it to a more traditional Bitcoin miner, MARA Holdings ( MARA ). Now, in terms of the earnings multiple, MARA trades at 232x , which creates a massive gap versus CLSK's valuation. If we compare all these companies in terms of their book value, we can see that both CleanSpark and MARA trade at suppressed valuations. Surely enough, IREN and CIFR have AI HPC contracted revenue supporting their pivot to a high-growth market, resulting in a higher multiple. But if tailwinds materialize tied to global market growth, CLSK should be able to benefit from the bullish trend and rebound from the current level. CLSK: Price/Book Value Versus Peers (YCharts) Why does this matter? It tells me that the market hasn't really priced in its AI HPC pivot. Quite honestly, I like it a lot, especially as CLSK is pursuing strategic investments like the one in greater Houston tied to AI and cloud capabilities. In my opinion, the market is likely to reprice CLSK at a higher premium sooner rather than later. To this, on a forward Price/Book value ratio of 3.54 , CLSK trades at more than a 21% discount versus the sector median of 4.51, which argues for my bullish thesis. CleanSpark is also a profitable company, and I love that it operates at above-market margins. The gross profit margin (TTM) of 55% highlights a 13% outperformance versus peers at 49%. The net income margin (TTM) of 48% signals a nearly 10x advantage versus peers at 5%. Surely enough, we need to account for Bitcoin volatility, and unless BTCUSD rebounds from here, CLSK is likely to experience a contraction on the bottom line. However, the stock is down 22% over the past month , and it tells me that it could already be priced in. Risks and Concerns The crypto community is concerned that the digital assets could enter a prolonged bear market. Could that happen? Sure. Investors anticipated an end-year rally, but that didn't happen, and now one can only guess what is likely to happen next. As I have flagged, there's a possibility of BTCUSD approaching its 200-week moving average at nearly $57,000. Although this would imply a 56% drop from the current levels, based on my analysis, CLSK should still mine profitably. But we all could agree that such a poor sentiment would dramatically weigh on CLSK's stock price. To the last point, this also shows why I think this AI HPC pivot was a great strategic decision. Nevertheless, it comes with an execution risk. If CLSK struggles to gain market position in the AI HPC space and doesn't sign multi-year agreements with hyperscalers, sentiment may be clouded. Also, if there are concerns tied to scaling the business and infrastructure, investors may favor alternatives in the market. This AI HPC pivot also depends on AI sentiment. If heavy Capex investments don't translate to meaningful top- and bottom-line growth, hyperscalers may cut spending, which could cloud a bullish narrative, and likely struggle to keep up with estimated growth projections for this high-growth market. CleanSpark is a Strong Buy CLSK is a high-volatility stock, and price action could be brutal. 52-week trading range shows a 4x difference in price, and trust me, it could be a difficult stock to stomach for long-term holders who favor a stable investment environment. But I think the upside and risk ratio here is compelling. Based on my analysis, it remains undervalued versus peers, and because of the low cost to mine BTC, it appears well-positioned to withstand a crypto winter if one occurs. There's a big gap between earnings multiple versus AI HPC peers, and in terms of Price/Book value, the market seems to be discounting the stock. If CleanSpark continues to execute well, I think it may rebound from these levels, and the market could reprice sooner rather than later. I sustain my Strong Buy rating. 23 Wall Street analysts forecast a $23.27 12-month price target, indicating a 101% upside. Time will tell, but I agree with analysts.
