Argo Blockchain PLC

("Argo" or "the Company")

Allotment of New Shares

Argo Blockchain plc, a global leader in cryptocurrency mining (LSE: ARB; NASDAQ: ARBK), announces the allotment of 8,147,831 new Ordinary Shares in connection with the Company's acquisition of DPN LLC.

In March 2021, the Company acquired DPN LLC along with the land held by DPN LLC for Helios, its flagship Bitcoin mining facility in Dickens County, Texas. The merger agreement with DPN LLC and the DPN LLC members (the "Agreement") contains certain milestones which trigger deferred consideration to be satisfied by the allotment of further ordinary shares of £0.001 each in the Company ("Ordinary Shares") to the DPN LLC members. Certain of the milestones have now been met and the Company is obliged to issue 8,147,831 new Ordinary Shares to the members of DPN LLC, credited as fully paid at a price per share of £0.4950. No further Ordinary Shares are owed to the DPN LLC members under the terms of the Agreement as the remaining milestones have not been met.

Application will be made for the 8,147,831 new Ordinary Shares to be admitted to the standard segment of the Official List and to trading on the Main Market of the London Stock Exchange. Admission is expected to occur at 8:00 a.m. on Monday, 13 June 2022. The new Ordinary Shares will rank pari passu with the existing Ordinary Shares of the Company.

Following Admission, the total number of Ordinary Shares in issue will be 477,825,166 and the total number of voting rights will therefore be 477,825,166. This figure may be used by shareholders of the Company as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the share capital of the Company under the FCA's Disclosure and Transparency Rules.
