Results of Placing

ACG Metals Limited (LSE:ACG, ACGW) today announces the successful completion of its Placing announced on 11 November 2025. The Company has raised gross proceeds of approximately US$15.0 million (equivalent to approximately £11.4 million) through the placing of 1,056,309 Placing Shares at the Issue Price of £10.80 per Placing Share.

The Placing was oversubscribed, receiving strong support from existing and new investors, allowing the Company to broaden its institutional following and market support.

The separate Retail Offer announced on 11 November 2025 remains open for individual investors until 4:45 p.m. (London time) on 12 November 2025 and the results of the Retail Offer and final results of the Fundraise will be made as soon as practicable thereafter.

As previously announced, the net proceeds from the Fundraise will part fund Phase 1 capex and be utilised, alongside internal cash resources, to fully fund the US$39 million Enriched Ore Treatment Project capex.

Stifel Nicolaus Europe Limited, Canaccord Genuity Limited, and Joh. Berenberg, Gossler & Co. KG, London Branch are acting as joint bookrunners in respect of the Placing.

The Placing Shares will, when issued, be credited as fully paid and rank pari passu in all respects with the existing issued Ordinary Shares of the Company, including, without limitation, the right to receive all dividends and other distributions declared, made or paid after the date of Admission (as defined below).

Applications will be made for the Placing Shares to be admitted to listing in the equity shares (transition) category of the Official List of the FCA and to be admitted to trading on the main market for listed securities of the London Stock Exchange (together, "Admission"). It is anticipated that Admission will become effective, and that dealings in the Placing Shares will commence, at 8.00 a.m. (London time) on 14 November 2025. The Placing is conditional upon, among other things: (i) the Placing Agreement not being terminated in accordance with its terms; and (ii) Admission becoming effective by 8.00 a.m. (London time) on 14 November 2025 (or such later time and/or date as the Company and the Joint Bookrunners may agree, being not later than 8.00 a.m. (London time) on 21 November 2025).

Artem Volynets, Chairman and Chief Executive Officer of the Company, commented:

"We're pleased with the strong demand shown in yesterday's placing, which was significantly oversubscribed. We appreciate the backing of our long-standing investors and are glad to welcome those joining us for the first time. The outcome is a clear endorsement of our team and strategy, which we will execute as planned."

The Enriched Ore Treatment Project gives us a clear path to bringing forward additional production, improving cash generation and unlocking value that wasn't recognised in the original mine plan. With this support behind us, we are well positioned to continue building ACG into a leading copper producer."

Capitalised terms not otherwise defined in the text of this announcement have the meanings given in the Company's announcement of 11 November 2025.

UK Product Governance Requirements

Solely for the purposes of the product governance requirements of Chapter 3 of the FCA Handbook Product Intervention and Product Governance Sourcebook (the "UK Product Governance Requirements"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the UK Product Governance Requirements) may otherwise have with respect thereto, the Placing Shares have been subject to a product approval process, which has determined that such Placing Shares are: (i) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each as defined in the FCA Handbook Conduct of Business Sourcebook; and (ii) eligible for distribution through all permitted distribution channels (the "UK Target Market Assessment"). Notwithstanding the UK Target Market Assessment, distributors should note that: the price of the Placing Shares may decline and investors could lose all or part of their investment; the Placing Shares offer no guaranteed income and no capital protection; and an investment in the Placing Shares is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom. The UK Target Market Assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the Placing. Furthermore, it is noted that, notwithstanding the UK Target Market Assessment, the Joint Bookrunners will only procure investors who meet the criteria of professional clients and eligible counterparties.

For the avoidance of doubt, the UK Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of Chapters 9A or 10A, respectively, of the FCA Handbook Conduct of Business Sourcebook; or (b) a recommendation to any investor or group of investors to invest in, or purchase or take any other action whatsoever with respect to the Placing Shares. Each distributor is responsible for undertaking its own target market assessment in respect of the Placing Shares and determining appropriate distribution channels.

EU Product Governance Requirements

Solely for the purposes of the product governance requirements contained within: (a) EU Directive 2014/65/EU on markets in financial instruments, as amended ("MiFID II"); (b) Articles 9 and 10 of Commission Delegated Directive (EU) 2017/593 supplementing MiFID II; and (c) local implementing measures (together, the "MiFID II Product Governance Requirements") and/or any equivalent requirements elsewhere to the extent determined to be applicable, and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the MiFID II Product Governance Requirements and/or any equivalent requirements elsewhere to the extent determined to be applicable) may otherwise have with respect thereto, the Placing Shares have been subject to a product approval process, which has determined that the Placing Shares are: (i) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each as defined in MiFID II; and (ii) eligible for distribution through all distribution channels as are permitted by MiFID II (the "EU Target Market Assessment"). Notwithstanding the EU Target Market Assessment, distributors should note that: the price of the Placing Shares may decline and investors could lose all or part of their investment; the Placing Shares offer no guaranteed income and no capital protection; and an investment in the Placing Shares is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom. The EU Target Market Assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the Placing. Furthermore, it is noted that, notwithstanding the EU Target Market Assessment, the Joint Bookrunners will only procure investors who meet the criteria of professional clients and eligible counterparties.

For the avoidance of doubt, the EU Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of MiFID II; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to the Placing Shares. Each distributor is responsible for undertaking its own target market assessment in respect of the Placing Shares and determining appropriate distribution channels.
