Closing of UK Restructuring Plan and Strategic Pivot Toward AI/HPC

Argo Blockchain plc (NASDAQ: ARBK) announces the closing of its restructuring plan under Part 26A of the Companies Act 2006 (the "Restructuring Plan"), as sanctioned by the High Court of Justice, Business and Property Courts of England and Wales by the sealed order issued on 11 December 2025, marking a significant milestone in its transformation and positioning the Company for long-term growth.

Key Highlights of Closing of the Restructuring Plan:

●    Enhanced Hashrate Capacity: The Company's nameplate hashrate has increased from approximately 1.8 EH/s to 2.4 EH/s, strengthening its competitive position in the Bitcoin mining sector.

●   Expanded Self-Mining Operations: Expanded self‑mining capacity to 28.5 MW through 13.5 MW of newly acquired infrastructure in Alabama; additionally secured electrical assets (2500 KVA transformers and switchgear) that can support up to 65 MW of incremental deployment at future sites.

●    Diversified Mining Portfolio: With the recent price momentum in Zcash, the Company has successfully deployed 1,400 Z11 miners, now actively contributing to revenue through Zcash mining.

●   Strengthened Balance Sheet: The Company's $40 million in outstanding 8.75% senior notes due 2026 (CUSIP: 040126 203) have been equitized pursuant to the Restructuring Plan, leaving the Company debt-free except for the $472k remaining mortgage on the Company's owned and operated Baie-Comeau facility.

●  Strategic Pivot to AI/HPC: The Company is exploring opportunities in artificial intelligence (AI) and high-performance computing (HPC) to diversify its revenue streams and leverage its infrastructure expertise.
