Argo Blockchain plc

("Argo" or "the Company")

October Update

Argo Blockchain plc, a global leader in cryptocurrency mining (LSE: ARB; NASDAQ: ARBK), provides the following announcement regarding certain strategic actions that were announced on 7 October 2022.

As previously disclosed, the Company signed a non-binding LOI with a strategic investor to raise approximately £24 million ($27 million) via a subscription for ordinary shares. The Company no longer believes that this subscription will be consummated under the previously announced terms. Argo is continuing to explore other financing opportunities.

The Company has also taken steps to further maximize liquidity and preserve cash. The Company sold 3,843 new-in-box Bitmain S19J Pro machines, representing ~384 PH/s of total hashrate capacity, for cash proceeds of ~£4.8 million ($5.6 million). These machines are the last batch of the original Bitmain order scheduled for installation in October 2022. As a result, the Company's total hashrate capacity remains at 2.5 EH/s.

No Assurance of Definitive Agreements

While Argo is exploring other financing opportunities, there can be no assurance that any definitive agreements will be signed or that any transactions will be consummated. Should Argo be unsuccessful in completing any further financing, Argo would become cash flow negative in the near term and would need to curtail or cease operations. The Company is endeavoring to complete such financing transactions to provide the Company with working capital sufficient for its present requirements, that is for at least the next twelve months from the date of this announcement.
