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

Full analysis →

Business Overview

  • Core business model: Energy and digital infrastructure company leveraging Bitcoin mining to optimize power use and develop AI inference and HPC capabilities
  • New emphasis: Acquisition of majority interest in Exaion SaS and joint venture with Starwood to develop AI and HPC infrastructure on power-rich sites
  • Strategic shift: Transition to asset-heavy model with ~70% owned portfolio capacity, enhancing control and margin durability versus prior asset-light approach
  • Quantitative highlight: 20% growth in total bitcoin holdings to 53,822 with $4.7 billion valuation and operating 490,000 mining rigs with 66.4 EH/s hashrate
  • Noteworthy fact: Acquisition of 240 MW wind farm in Texas for low-cost behind-the-meter data center and letter of intent with MPLX for expanded natural gas access

Risk Factors

  • Legal risk: Goodwill impairment $82.8M due to ASC 350 triggered by sustained market capitalization decline and market conditions in 2025
  • Macroeconomic risk: Bitcoin price dropped to $87,498 at 2025 year-end from $93,354 in 2024, causing $422.2M loss in bitcoin asset value
  • Operational risk: $26.0M impairment from storm-damaged mining equipment at Garden City site in 2025
  • Competitive risk: Increased global network hashrate and difficulty post-April 2024 halving reduced bitcoin mined by 7% YoY to 8,799 BTC in 2025
  • Financial risk: $350M borrowings collateralized by 5,938 bitcoin with 8.85%-10.5% interest rates, exposing balance sheet to bitcoin price volatility

Management Discussion & Analysis

  • Revenue and bitcoin monetization strategy: began selling bitcoin in H2 2025 to fund operations; plan to continue opportunistic monetization in 2026 for liquidity and capital projects
  • Operational scale: total energized hashrate 66.4 EH/s across 1,861 MW capacity including 779 MW owned sites; Granbury TX lead site with 12.3 EH/s energized hashrate
  • Segment performance: Granbury TX best performing with 12.3 EH/s; international sites 2.3 EH/s; hosted sites provide 29.2 EH/s at 537 MW capacity
  • Capital allocation: expanded by acquiring Exaion (France) and 42 MW data center in Nebraska post-year-end; no specific buybacks/dividends or capex amounts disclosed
  • Outlook and risks: continuing diversification into AI and HPC markets leveraging energy ownership; regulatory uncertainty around Bitcoin mining and AI expansion highlighted as key risks
