Argo Blockchain plc provides the following updates regarding its proposed restructuring plan under Part 26A of the Companies Act 2006 (the "Restructuring Plan").

Town Hall Meeting

As mentioned in the Company's explanatory statement accompanying the Restructuring Plan, the Company will hold an online only "town hall" meeting at which management will address retail holders of the Company's notes and shares on the Restructuring Plan and the Retail Advocate will also address retail holders and reiterate his role.

The main purpose of the Town Hall is to enable retail holders of the Company's notes and shares to have the opportunity to ask questions about the Restructuring Plan and make their views about any aspect of it known.

If you have any questions or concerns you are encouraged to attend.  You are free to attend (and indeed are encouraged to do so) even if you hold your notes or shares through a broker or other intermediary.

The town hall meeting will be held online on Wednesday 19 November 2025 at 4 p.m. (GMT) / 11 a.m. (Eastern).   Those wishing to attend the town hall meeting should register in advance at:

Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on the Company's current beliefs, expectations and assumptions regarding the future of its business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of the Company's control. The information in this announcement about the proposed Restructuring Plan and its expected effects; the Company's operating and financial outlook; and internal estimates, projections, forecasts, and valuation analyses are forward-looking statements. Therefore, you should not rely on any of these forward-looking statements. Important factors that could cause the Company's actual results and financial condition to differ materially from those indicated in the forward-looking statements include market conditions; the Company's ability to implement the proposed Restructuring Plan on the expected timeline or at all; the ability to retain the Company's listing on Nasdaq; operational, financial, regulatory, tax and legal risks; assumptions underlying revenue, EBITDA and valuation estimates; and the principal risks and uncertainties described in the risk factors set forth in the Company's Annual Report and Financial Statements and Form 20-F for the year ended 31 December 2024.
