Material Changes vs. Prior Period
- Revenue Growth: Revenue increased 34% year-over-year for the quarter ($47.6M vs. $35.6M) and 5% for the six-month period ($82.0M vs. $78.0M). This was driven by higher average Bitcoin prices ($98,219 vs. $65,984 per coin in Q2), partially offset by a decrease in Bitcoin mined due to the April 2024 halving and increased network difficulty.
- Net Loss Expansion: Net loss widened significantly to $79.8M for the six months ended June 30, 2025, compared to $20.5M in the prior year. This was primarily due to a $28.2M increase in stock-based compensation, higher power costs, and acquisition-related expenses.
- Acquisition of Beowulf E&D: On May 21, 2025, the company acquired Beowulf E&D for approximately $54.6M (cash and stock). This resulted in $55.5M of goodwill and $30.0M in contingent consideration liabilities. A $1.6M loss was recorded due to the fair value remeasurement of these liabilities.
- Cost of Revenue: Increased 18.3M for the six-month period, driven by higher power prices and expanded capacity, partially offset by $5.9M in demand response program proceeds.
- Capital Expenditures: Cash used in investing activities increased to $132.1M (vs. $93.6M prior year) due to $213.6M in purchases/deposits for plant and equipment and the acquisition of Beowulf E&D.
Guidance, Outlook, and Risks
- HPC Expansion: The company is on track to deliver 72.5 MW of HPC colocation capacity to Core42, with revenue recognition expected in the second half of 2025 as data halls become operational. The Lake Mariner Facility has the capacity to expand to 500 MW near-term and 750 MW with upgrades.
- Bitcoin Mining Economics: The cost to mine one Bitcoin (excluding depreciation) was $45,608 in Q2 2025, representing 46.4% of the value of the Bitcoin mined. Power costs remain the most significant expense, influenced by volatile market rates and weather conditions.
- Liquidity: The company holds $90.0M in cash and cash equivalents. It received $90.0M in prepaid rent from the Core42 HPC lease, recorded as deferred revenue. The company has a $200M share repurchase program authorized through December 2025, with $33.3M utilized in the first six months of 2025.
- Key Risks:
- Bitcoin Price Volatility: A 10% decrease in Bitcoin price would increase net loss by approximately $8.2M.
- Power Costs: A 10% increase in power prices would increase net loss by approximately $4.7M.
- Regulatory and Operational: Risks include changes in environmental regulations, cybersecurity threats, and the ability to secure project financing for expansion milestones.
Investor Verification Checklist
- Contingent Consideration: Verify the fair value assumptions and probability of achieving the $32M in remaining earnout milestones (cash and stock) related to the Beowulf E&D acquisition.
- HPC Lease Commencement: Confirm the timeline for the commencement of the Core42 HPC leases and the recognition of the $90M prepaid rent revenue.
- Power Cost Volatility: Monitor the impact of New York wholesale electricity pricing on the cost of revenue, given the variable nature of the power supply at Lake Mariner.
- Stock-Based Compensation: Review the sustainability of the $40M stock-based compensation expense recorded in the first half of 2025 and its impact on future GAAP net loss.
- Debt Covenants: Assess compliance with covenants related to the $500M 2.75% Convertible Senior Notes due 2030, particularly regarding conversion triggers and redemption rights.
