• The company's ability to repay its 2030 and 2032 Notes upon maturity is a potential risk.
• Security and cybersecurity threats pose a risk to operations and digital assets.
• The company relies on a third-party mining pool operator for revenue payouts and third parties for wallet maintenance.
• The company is subject to legal proceedings, including a class action lawsuit and shareholder derivative actions, the outcomes of which are uncertain.

Future Outlook

The company is actively pursuing opportunities in AI and HPC data center development, expanding its infrastructure and power capacity. While Bitcoin mining remains a core activity, the company is diversifying its business model. Management believes current cash and Bitcoin holdings, along with operational cash flow, will be sufficient for the next 12 months and the foreseeable future, but acknowledges the potential need for additional capital for growth and unforeseen circumstances.

Management Comments

• We intend to continue our growth in these regions and are actively developing plans for additional capacity in these states and other regions.
• We design our infrastructure to responsibly secure and support both bitcoin mining and AI and HPC workloads.
• We expect to continue increasing our computing power through 2026 and beyond as we expand infrastructure at our owned sites in Tennessee, Georgia, Mississippi, and Wyoming, while also pursuing regional expansion opportunities and evaluating strategic acquisition targets.
• We believe we operate a highly efficient fleet of miners.
• Management believes that providing this non-GAAP financial measure that excludes these items allows for meaningful comparisons between the Company's core business operating results and those of other companies, and provides the Company with an important tool for financial and operational decision making and for evaluating its own core business operating results over different periods of time.

Industry Context

StockSavvy.ai notes that CleanSpark's strategic pivot towards AI and HPC data centers reflects a broader industry trend of leveraging existing energy infrastructure and expertise to capitalize on the growing demand for computing power in these sectors. This diversification aims to mitigate the inherent volatility of the Bitcoin market.

Comparison to Industry Standards

• CleanSpark's average operating energy efficiency of 16.2 J/TH for its miner fleet is competitive within the Bitcoin mining industry, where efficiency is a key driver of profitability.
• The company's hashrate of 47.3 EH/s as of March 31, 2026, represents approximately 4.66% of the global hashrate, indicating a significant but not dominant market share compared to larger mining operations.
• The cost to mine one Bitcoin, including direct energy costs, was $45,411 for the three months ended March 31, 2026. This figure is sensitive to energy prices and Bitcoin's market value, making direct comparisons challenging without considering specific power contracts and operational efficiencies of peers.
• The company's expansion into AI and HPC data centers places it in a rapidly growing market. Competitors in this space include established cloud providers and specialized data center developers, where CleanSpark's success will depend on its ability to secure power, scale operations, and attract hyperscaler clients.

Corporate Governance

Legal Proceedings

• Hasthantra v. CleanSpark, Inc. et al.: Class action complaint alleging material misstatements and omissions related to acquisitions and expansion. Class certification granted; motions to exclude expert witnesses are pending.
• Consolidated Smith Derivative Actions: Shareholder derivative actions against officers and directors alleging breach of fiduciary duty, unjust enrichment, and corporate waste. Case stayed pending Special Litigation Committee's motion to dismiss; court denied motion to defer without prejudice.

Stakeholder Impact

• Shareholders: The significant net loss and decrease in Bitcoin's fair value negatively impact shareholder value. The company's diversification into AI/HPC may offer future growth potential.
• Creditors: The company has substantial debt obligations, including convertible notes totaling $1.79 billion, which could impact its financial flexibility.
• Employees: Increased payroll expenses and stock-based compensation suggest continued investment in personnel, potentially impacting morale and retention.
• Suppliers: The company continues to engage in significant procurement of miners and equipment, impacting suppliers in the hardware manufacturing sector.

Next Steps

• Continue expansion of data center operations for AI and HPC workloads.
• Advance design and permitting activities for greenfield data-center sites.
• Integrate treasury management strategies, including derivative contracts, into regular operations.
• Evaluate opportunities to expand the business through potential acquisitions.
• Continue to monitor and manage energy prices and Bitcoin market conditions.

Key Dates

Recommendation

While CleanSpark is strategically diversifying into the growing AI/HPC data center market, the current financial performance is significantly hampered by the volatility of Bitcoin and increased operational costs, leading to substantial net losses. The company's substantial debt load also presents a risk. A 'hold' recommendation is appropriate, awaiting clearer signs of profitability from its core mining operations or successful execution of its AI/HPC strategy.
