Vast Resources plc
("Vast" or the "Company")

Result of Retail Offer for Existing Vast Shareholders

Vast, the AIM quoted mining company, is pleased to confirm, further to the announcement made on 3 August 2026, the result of the Retail Offer via BookBuild at the Issue Price of 6.25p per New Ordinary Share.

The Company announces that it has conditionally raised aggregate gross proceeds of £300,000 pursuant to the Retail Offer. Accordingly, the Company will issue a total of 4,800,000 New Ordinary Shares at the Issue Price pursuant to the Retail Offer. The Retail Offer was oversubscribed, with allocations made in line with soft pre-emption principles. Where demand exceeded their soft pre-emptive entitlement, Shareholders were allocated on a pro-rata basis.

Admission of the Retail Offer Shares is subject to approval of, inter alia, the Proposed Transaction which will be voted upon at the Company's General Meeting ("Shareholder Approval").

In addition to the Retail Offer, the Company is also conducting a placing of new ordinary shares (the "Placing Shares" and together with the Retail Offer Shares, the "New Ordinary Shares") at the Issue Price (the "Placing" and together with the Retail Offer, the "Issue"). A separate announcement has been made regarding the Placing and its terms. For the avoidance of doubt, the Retail Offer is not part of the Placing.

In addition, as described in paragraph 13 of Part I of the Admission Document, the Share Consolidation requires the total number of Existing Ordinary Shares in issue to be exactly divisible by 25. Accordingly, the Company will issue 16 Existing Ordinary Shares at 0.25 pence per share (the "Additional Existing Shares"). Following the Share Consolidation, the Additional Existing Shares will represent one New Ordinary Share, which will be aggregated with other fractional entitlements and dealt with in accordance with the arrangements set out in paragraph 13 of Part I of the Admission Document.

Admission of Shares

Subject to Shareholder Approval at the Company's General Meeting, application will be made for the Retail Offer Shares to be admitted to trading on AIM on 19 August 2026.

Total Voting Rights on Admission

Following Admission, the total number of New Ordinary Shares in issue in the Company will be 1,645,941,556 New Ordinary Shares of £0.025 each. This figure may be used by shareholders 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 Company under the FCA's Disclosure Guidance and Transparency Rules.

The New Ordinary Shares, when issued, will be fully paid and will rank pari passu in all respects with each other and with the New Ordinary Shares to be issued pursuant to the Placing, the Subscription and the Company's Existing Ordinary Shares, including, without limitation, the right to receive all dividends and other distributions declared, made or paid after the date of issue. The New Ordinary Shares

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 MiFIR 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 MiFIR Product Governance Requirements) may otherwise have with respect thereto, the Retail Offer Shares have been subject to a product approval process, which has determined that the Retail Offer 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 paragraphs 3.5 and 3.6 of COBS; and (ii) eligible for distribution through all permitted distribution channels (the "Target Market Assessment"). Notwithstanding the Target Market Assessment, distributors should note that: the price of the Retail Offer Shares may decline and investors could lose all or part of their investment; the Retail Offer Shares offer no guaranteed income and no capital protection; and an investment in the Retail Offer 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 Target Market Assessment is without prejudice to any contractual, legal or regulatory selling restrictions in relation to the Retail Offer.

For the avoidance of doubt, the Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of Chapters 9A or 10A respectively of COBS; 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 Retail Offer Shares. Each distributor is responsible for undertaking its own target market assessment in respect of the Retail Offer Shares and determining appropriate distribution channels.
