Latest 10-K, fiscal year ended Dec 31, 2025

Full analysis →

Business Overview

  • Core business: Vertically integrated owner/operator of utility-scale, liquid-cooled HPC data centers for AI, machine learning, and cloud applications
  • New focus: Strategic shift prioritizing HPC hosting as primary growth over legacy bitcoin mining operations
  • Competitive advantage: Long-term, credit-enhanced contracts with Google-backed customer Fluidstack totaling 918 MW contracted IT load across Lake Mariner and Abernathy campuses
  • Quantitative metric: 141 full-time US-based employees as of filing; aiming for 250-500 MW new HPC capacity contracted annually
  • Noteworthy fact: Conversion of former coal plant site into flagship HPC campus with near-term capacity expansion to 500 MW and up to 750 MW pending NYISO approvals

Risk Factors

  • Regulatory/legal risk: Uncertainty from evolving U.S. cryptocurrency regulations impacting bitcoin mining operations and potential future compliance costs
  • Geopolitical/macroeconomic threat: Exposure to increased U.S. tariffs, trade restrictions risking supply chain delays and higher material costs for data center expansions
  • Operational/supply chain vulnerability: Dependency on reliable power supply with risks of outages, capacity constraints, and costly delays for HPC and bitcoin mining data centers
  • Competitive/market disruption risk: AI efficiency improvements possibly reducing demand for high-density data center infrastructure, threatening HPC hosting revenue growth
  • Financial/structural risk: Capital-intensive HPC expansions requiring additional financing, raising risks of shareholder dilution or restrictive debt covenants impacting cash flow

Management Discussion & Analysis

  • Revenue $168.5M in 2025, up $28.6M YoY from $140.1M in 2024; digital asset revenue $151.6M (+$11.5M), HPC lease revenue $16.9M (new in 2025)
  • Cost of revenue (excl. depreciation) $82.7M in 2025 vs $62.6M in 2024; power expense major driver, partly offset by $17.7M demand response proceeds
  • Best segment: Digital asset revenue $151.6M (90% total revenue), worst: Bitcoin mining production down to 1,496 BTC vs 2,177 BTC weighted by halving event
  • Capital allocation shift: No new bitcoin mining investments; focus on HPC data center development with strategic acquisitions of Beowulf E&D and new long-term ground leases
  • Outlook: Revenue mix shifting to HPC leasing, growth dependent on construction timing, power access, and project financing; Morgantown power plant purchase expected Q2 2026 closing
