Sound Energy plc

("Sound Energy" or the "Company")

PDMR Dealings, Exercise of Options and Total Voting Rights

Sound Energy, the AIM-listed transition energy company, announces that Graham Lyon, Non-Executive Chair, on 23 June 2026 purchased a total of 603,093 ordinary shares of £0.001 each in the Company ("Ordinary Shares") at an average purchase price of £0.020724 per share in the Company.

The Company also announces that Mr Lyon exercised nil-cost options over 774,094 Ordinary Shares. The Company has therefore issued to Mr Lyon a total of 774,094 new ordinary shares of £0.001 each in the Company ("New Ordinary Shares"), pursuant to the exercise of options.

As a result of the above transactions, which are detailed in each PDMR Notification Dealing Form below, Mr Lyon's interest in the Company is 2,078,413 Ordinary Shares, representing 0.91% of the issued share capital.

Application has been made for the admission of the New Ordinary Shares to trading on AIM ("Admission"). The New Ordinary Shares will rank pari passu with the existing Ordinary Shares and it is expected that Admission will become effective on or around 8.00 a.m. on or around 29 June 2026.

Following Admission, the Company's issued share capital will consist of 226,928,560 Ordinary Shares of £0.001 each with voting rights in the Company and 2,180,000 Sanctioned Holding Shares of £0.01 each totalling 229,108,560 Ordinary Shares with voting rights. The Company does not hold any Ordinary Shares in treasury. This figure of 229,108,560 may be used by shareholders in the Company as the denominator for the calculations by which they will determine if they require to notify their interest in, or a change to their interest in, the share capital of the Company under the UK Financial Conduct Authority's Disclosure Guidance and Transparency Rules.

The Company notes that 2,180,000 ordinary shares in the Company (prior to the Share Capital Reorganisation announced on 10 February 2026) (the "Sanctioned Shares") are held by a shareholder who is currently subject to applicable sanctions (the "Sanctioned Shareholder"). While the Sanctioned Shareholder remains subject to such sanctions, the Board has taken the view that the Company should not recognise the exercise of voting rights attaching to the Sanctioned Shares.

If, in due course, the Sanctioned Shareholder ceases to be subject to applicable sanctions (or the relevant restrictions otherwise no longer apply) , the Board currently intends to propose an appropriate resolution at the Company's next Annual General Meeting (or, if the Board considers it necessary or appropriate, at a general meeting) to seek shareholder approval to implement the Share Capital Reorganisation in relation to the Sanctioned Shares as the Sanctioned Shares were excluded from the Share Capital Reorganisation. Any such proposal would be announced separately in due course.
