The Thesis
CleanSpark is a digital infrastructure company that earns money by mining bitcoin and developing sustainable data centers. The company generated $0.77 billion in revenue during fiscal 2025, a growth of 102% over the prior year. The recent pivot to commercializing power for AI and high-performance computing marks the structural shift that expands the business beyond simple cryptocurrency mining.
If you own CleanSpark, you are betting on four things at once.
In our view, there is meaningful upside still ahead, driven by how the market is underestimating the value of CleanSpark's power pipeline for AI customers. The case for owning the stock remains strong if energized hash rate keeps climbing and the first AI contracts are signed. We think this is one of the cleaner ways for long-term investors to own the intersection of digital assets and compute infrastructure.
Numbers at a Glance
What does it do?
CleanSpark is a growth business that earns money by running massive fleets of specialized computers to secure the Bitcoin network. The company secures low-cost electricity and converts it into compute power, measured in "hashrate," which earns them newly minted bitcoin and transaction fees from the network. This process is essentially a way to monetize cheap, sustainable energy at scale. The company also provides energy technology solutions like solar and storage for microgrids, though mining is the primary driver.
Where does revenue come from?
The vast majority of revenue comes from mining bitcoin rewards and transaction fees earned through its data centers. The Digital Currency Mining segment accounts for nearly the entire revenue stream, with the Energy segment providing a smaller portion through engineering and software for power grids. The company's revenue is highly sensitive to the market price of bitcoin and the difficulty level of the network's mining calculations.
Who are its customers?
CleanSpark serves the global Bitcoin network as its primary customer while preparing to host AI and high-performance computing (HPC) clients. The company earns its primary income from the network protocol itself, which pays out 3.125 bitcoin per block discovered by miners. As of the latest reporting, the company held $925.2 million in bitcoin and had doubled its power under contract to over 1.8 gigawatts. The pivot to AI/HPC targets enterprise clients who need the massive power capacity CleanSpark has secured in states like Georgia and Texas.
What gives it staying power?
CleanSpark's staying power comes from its ownership of high-capacity power infrastructure and globally competitive energy rates. Because mining is a race to the lowest cost, having 1.8 GW of power and owned land prevents competitors from easily pricing them out during market downturns.
Where is it headed?
The single biggest strategic bet is the expansion into AI and high-performance computing data centers. Management is developing a 300 MW site in Brazoria to move beyond just mining and into the market for renting out compute space. If this works, it turns a volatile mining business into a more predictable infrastructure landlord for the AI boom.
Revenue is currently under pressure as the business absorbs the impact of the latest bitcoin halving. While annual revenue grew 102% in FY2025, the $136.4 million reported in the most recent quarter was a 24.9% decline. This drop highlights how sensitive the company is to the difficulty of mining and the rewards paid out by the network.
Free cash flow is heavily negative because CleanSpark is in a massive build-out phase. The company burned over $1.02 billion in cash last year to buy next-generation mining rigs and build out power infrastructure. This gap between earnings and cash reveals a business that must continuously spend to maintain its competitive edge in compute power.
The balance sheet is leveraged but carries a massive liquid safety net in the form of bitcoin. While the company has $1.8 billion in long-term debt, it also holds $925.2 million in bitcoin and $260.3 million in cash. This "HODL" strategy provides a buffer against debt obligations, provided the market value of bitcoin remains stable or climbs.
CleanSpark is a financially aggressive business whose results are tied to crypto prices and heavy infrastructure spending.
The company successfully doubled its power under contract to 1.8 gigawatts to prepare for future growth. This move secures the essential raw material for compute, which is electricity, ahead of competitors. It ensures the company has a clear path to expand its hash rate once new machines are deployed.
Net losses reached $378.3 million this quarter, driven by higher operating costs and hardware depreciation. If the cost to mine a single bitcoin rises faster than its market price, the current infrastructure spending will become harder to justify. Management must prove they can reach profit without relying solely on a surging bitcoin price.
The Bitcoin mining industry is part of the broader digital infrastructure market, which is roughly $15 billion today and growing at 20% annually as global hash rate climbs. By 2028, the market for high-performance compute and mining infrastructure is expected to exceed $30 billion. Pricing power in this industry is essentially non-existent because bitcoin is a commodity, meaning the only way to win is to have the lowest electricity costs. CleanSpark is a leader in the US market, using its massive power pipeline to transition from a pure miner into a diversified compute provider.
The competitive dynamic is brutally efficient because every miner in the world competes for the same fixed number of bitcoin rewards. Barriers to entry are high due to the difficulty of securing hundreds of megawatts of power, but once built, there is little to stop a competitor from outspending on better hardware. Success depends entirely on maintaining a lower cost of production than the global average to survive market crashes.
Marathon Digital(MARA) and Riot Platforms(RIOT) are the primary threats, competing directly for the same low-cost power and latest mining rigs from manufacturers. Iris Energy(IREN) is an emerging threat in the AI/HPC space, as they were earlier to pivot their infrastructure toward high-margin data center hosting. Core Scientific is the most dangerous competitor because they have already secured major enterprise AI contracts, proving the business model CleanSpark is still building.
CleanSpark is holding its ground by aggressively expanding its hash rate, though its 24.9% revenue drop last quarter shows it is not immune to industry-wide pressure.
The primary source of protection for CleanSpark is efficient scale through its ownership of massive power infrastructure. By controlling 1.8 gigawatts of power and owning its data center sites, the company can operate at a scale that smaller miners cannot replicate. This scale allows them to negotiate better electricity rates and secure bulk hardware discounts.
The company's negative ROIC of -6.4% and the heavy net loss this quarter suggest that this moat is still being built and is not yet yielding structural profits. While the revenue growth of 102% last year proves the company can scale quickly, the lack of GAAP profitability shows the competitive advantage is currently focused on volume rather than pricing power. The numbers suggest a business that is winning the race for capacity but is still vulnerable to the extreme volatility of its primary product.
The moat is strengthening as the company secures more power for AI, but its survival still depends on bitcoin prices.
Doubled MW under contract but revenue fell 24.9% YoY in Q2.
Invested over $1B in FCF while maintaining $925M BTC treasury.
Management ownership present but company relies heavily on equity dilution for growth.
Capital Allocation Track Record
Management has shown high operational skill in securing massive power capacity, which is the rarest resource in the data center industry. However, the heavy reliance on share issuance to fund growth and the recent drop in quarterly revenue keep the rating at adequate. The success of Matt Schultz will be judged by whether he can actually convert the company's power pipeline into high-margin AI hosting contracts.
