Result of Fundraise

ATOME Energy (AIM: ATOM), the company focused on green hydrogen and ammonia production globally with projects in both Europe and South America, announced on 12 December 2022 a fundraising comprising a placing of new Ordinary Shares (the "Placing") at a price of 106.2 pence per new ordinary share ("Placing Price"), an offer via PrimaryBid (the "PrimaryBid Offer") at the Placing Price and at the discretion of the Directors, the possible issue of further new ordinary shares at the Placing Price should there be appropriate demand (the "Further Issue") (together the "Fundraise").

The Company is pleased to announce that the PrimaryBid Offer has successfully raised gross proceeds of £0.55 million through the issue of 517,891 new ordinary shares ("Retail Offer Shares"). In addition, the Further Issue also closed at the same time as the PrimaryBid Offer raising further gross proceeds of £0.49 million through the issue of  460,298 new ordinary shares (the "Further Issue Shares").

As announced on 12 December 2022, the Company is issuing 2,542,364 new ordinary shares in the Company pursuant to the Placing (the "Placing Shares").

In aggregate therefore, pursuant to the Fundraise, the Company is issuing 3,520,553 new ordinary shares, comprising the Placing Shares, the Retail Offer Shares, and the Further Issue Shares (together the "New Ordinary Shares") raising gross proceeds of approximately £3.74 million.

Admission

The New Ordinary Shares will rank pari passu with the Company's existing ordinary shares. Following the issue of the New Ordinary Shares, the Company's issued share capital will consist of 36,020,553 Ordinary Shares. Accordingly, the figure of 36,020,553 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.
