Result of Bookbuild

Solvonis Therapeutics plc (LSE: SVNS), an innovative biotechnology company co-developing therapeutics for mental health disorders, is pleased to announce that, further to the Company's announcement on 15 May 2025 (the "Fundraise Launch Announcement"), the Company has conditionally raised gross proceeds of approximately £2.0 million (the "Fundraise") through the proposed issue of 1,538,461,529 new ordinary shares of £0.001 each in the Company (the "Fundraise Shares") with certain existing and new institutional and other investors at the Issue Price of 0.13 pence per Fundraise Share.

The Fundraise Shares, in aggregate, represent approximately 67.01 per cent of the issued share capital of the Company prior to the Fundraise.

Allenby Capital Limited ("Allenby") and Singer Capital Markets Securities Limited ("Singer") acted as joint brokers and joint bookrunners in respect of the Fundraise.

Admission and Total Voting Rights

Application will be made for the 3,612,840,057 Fundraise Shares and Consideration Shares, as defined in the Fundraise Launch Announcement (together the "New Ordinary Shares"), to be admitted to trading on the Main Market of the London Stock Exchange and to listing in the FCA's Official List Equity Shares (transition) category ("Admission").

It is expected that Admission will become effective and that dealings in the New Ordinary Shares will commence at 8.00 a.m. on 27 May 2025. The issue and allotment of the Fundraise Shares is conditional upon, inter alia, Admission becoming effective and the placing agreement entered into between the Company, Allenby and Singer (the "Placing Agreement") not being terminated in accordance with its terms.

Following Admission, the Company's enlarged issued ordinary share capital will comprise 5,908,770,690 ordinary shares. This figure may be used by shareholders in the Company as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change in their interest in, the share capital of the Company under the FCA's Disclosure Guidance and Transparency Rules.
