The RetailBook Offer

ACG Metals Limited (LSE:ACG, ACGW) is pleased to announce a conditional retail offer of new Class A ordinary shares in the capital of the Company ("Ordinary Shares") via RetailBook (the "RetailBook Offer") at an issue price of £10.80 per new Ordinary Share (the "Issue Price"), being a discount of 6.1 per cent to the closing mid-price of the Company's existing Ordinary Shares on 10 November 2025 (the "Retail Shares") to raise gross proceeds of approximately US$0.5 million (approximately £0.4 million). The Company is also conducting a placing of new Ordinary Shares (the "Placing Shares") to institutional investors by way of an accelerated bookbuilding process (the "Placing", together with the RetailBook Offer, the "Fundraise") as announced by the Company earlier today. For the avoidance of doubt, the RetailBook Offer is not part of the Placing.

The Company has separately announced the completion of a scoping level study to treat existing enriched ore at the Company's Gediktepe mine in Türkiye (the "Enriched Ore Treatment Project").

The RetailBook Offer is conditional on the new Ordinary Shares to be issued pursuant to the RetailBook Offer and the Placing being admitted to listing in the equity shares (transition) category of the Official List of the Financial Conduct Authority and admitted to trading on the main market for listed securities of London Stock Exchange plc ("Admission"). Admission is expected to take place at 8:00 a.m. on 14 November 2025. Completion of the Retail Offer is conditional, inter alia, upon completion of the Placing.

The Company will use the net proceeds to part-fund the Enriched Ore Treatment Project.

Reason for the RetailBook Offer

The RetailBook Offer is open to eligible investors resident and physically located in the United Kingdom following release of this announcement. The RetailBook Offer is expected to close at 4:45 p.m. on 12 November 2025 and may close earlier at the discretion of the Company or if it is oversubscribed.

The Retail Shares and the Placing Shares will, when issued, be credited as fully paid and will rank pari passu in all respects with existing Ordinary Shares including the right to receive all dividends and other distributions declared, made or paid after their date of issue.

Some partners may only accept applications from existing shareholders and/or existing customers.

There is a minimum subscription of £250 per investor. The terms and conditions on which investors subscribe will be provided by the relevant financial intermediaries including relevant commission or fee charges. Note, no commission will be charged to investors by RetailBook in connection with the RetailBook Offer.

The equity shares (transition) category of the Official List is a closed category for companies previously listed on the standard listing segment, which has lower ongoing obligations than the equity shares (commercial companies) category. A prospective investor should be aware of the risks of investing in such companies and should make the decision to invest only after careful consideration and, if appropriate, consultation with an independent financial adviser.
