CleanSpark, Inc. (CLSK) - Q2 2025 10-Q Summary

Business Context and Reporting Period

CleanSpark, Inc. is a leading Bitcoin mining company operating data centers across Georgia, Mississippi, Tennessee, and Wyoming. This report covers the quarterly period ended March 31, 2025 (Q2 Fiscal 2025). The Company operates a fleet of approximately 313,000 miners with a hashrate of 42.4 EH/s, representing roughly 5.08% of the global network hashrate. The Company recently completed the acquisition of GRIID Infrastructure Inc. in October 2024 and launched an in-house Bitcoin treasury function in April 2025.

Key Financial Metrics

Note: Q2 2025 Net Loss includes a $127.7M unrealized loss on the fair value of Bitcoin holdings. YTD 2025 Net Income includes a $90.5M unrealized gain on Bitcoin.

Material Changes vs. Prior Period

• Revenue Growth: Bitcoin mining revenue increased 63% QoQ and 85% YoY, driven primarily by a higher average Bitcoin price ($92,870 vs. $55,046 in Q2 2024) and a 53% increase in miners in service (205,412 vs. 133,963). This growth offset the 50% reduction in block rewards due to the April 2024 halving.
• Cost Structure: Cost of revenues (excluding D&A) rose 149% QoQ to $85.4M, primarily due to increased energy costs ($82.7M) associated with expanded operations. Average energy cost per kWh increased to $0.060 from $0.043.
• Debt Expansion: Total long-term debt surged to $641.7M from $7.2M in the prior year-end, driven by the issuance of $650M in 0% Convertible Senior Notes due 2030 in December 2024.
• Bitcoin Valuation Impact: The adoption of ASC 350-60 requires Bitcoin to be marked-to-market. Q2 2025 saw a $127.7M unrealized loss due to Bitcoin price fluctuations, whereas Q2 2024 recorded a $119.7M unrealized gain.
• Acquisitions: The Company completed the GRIID Infrastructure acquisition (Oct 2024) and several asset acquisitions in Tennessee and Georgia, significantly expanding its footprint and goodwill (increased to $132.2M).

Guidance, Outlook, and Risks

• Treasury Strategy: In April 2025, CleanSpark launched an in-house Bitcoin treasury function to trade Bitcoin and related financial products, shifting toward a balanced approach between monetizing production and building long-term holdings.
• Liquidity: The Company maintains strong liquidity with $838.2M in working capital. It holds a $200M line of credit with Coinbase (amended in April 2025) and $650M in convertible notes.
• Internal Controls: Management concluded that disclosure controls and procedures were not effective as of March 31, 2025, due to material weaknesses in internal controls over financial reporting (specifically regarding IT general controls, payroll, and property/equipment). Remediation efforts are underway.
• Risk Factors: Key risks include Bitcoin price volatility, regulatory changes (including potential U.S. strategic Bitcoin reserve impacts), supply chain disruptions for mining hardware, and the ability to remediate internal control weaknesses.

Investor Verification Checklist

• Bitcoin Price Sensitivity: Verify the impact of Bitcoin price volatility on reported Net Income, as unrealized gains/losses are now included in earnings under ASC 350-60.
• Debt Covenants: Review the terms of the new $650M Convertible Notes and the $200M Coinbase Line of Credit for potential dilution or liquidity triggers.
• Internal Control Remediation: Monitor progress on remediation of material weaknesses in internal controls, particularly regarding IT general controls and payroll processing.
• Energy Costs: Track the trend in average cost per kWh ($0.060 in Q2 2025) and its impact on the "cost to mine" metric relative to Bitcoin price.
• Hashrate Growth: Confirm the deployment of new miners and the resulting hashrate growth to offset the effects of the Bitcoin halving.
