("Sound Energy" or the "Company")

Announcement Regarding the Possible Offer for Angus Energy Plc

Further to its announcement on 18 January 2022 in relation to a possible all-share offer for the entire issued and to be issued share capital of Angus Energy Plc ("Angus"), Sound Energy confirms it does not intend to make an offer under Rule 2.7 of the City Code on Takeovers and Mergers (the "Code") to acquire Angus.

Following Sound Energy's customary and well-established due diligence review process and after careful consideration, the Company has concluded that it will not pursue an acquisition of Angus as originally contemplated and outlined in its announcement of 18 January 2022.

We would like to thank the Angus management team for their time and consideration of this potential transaction.

The Company will maintain a disciplined framework while continuing to evaluate a range of compelling strategic opportunities.

Sound remains firmly focused on delivering the phased development of its Tendrara Concession in Morocco, having issued the Notice to Proceed for the Phase 1 micro LNG project per its announcement on 16 February 2022 and continues to progress the Phase 2 pipeline project per its announcement on 14 March 2022.

This is a statement to which Rule 2.8 of the Code applies.

For the purposes of Note 2 to Rule 2.8 of the Code, Sound Energy reserves the right to make or participate in an offer or possible offer for Angus (and/or take any other action which would otherwise be restricted under Rule 2.8 of the Code) within 6 months of the date of this announcement:

i.)   with the agreement of the board of directors of Angus;

ii.)  following the announcement of a firm intention to make an offer for Angus by or on behalf of a third party;

iii.)  following the announcement by Angus of a proposal for a "whitewash" (as referred to in Note 1 of the Notes on Dispensations from Rule 9 of the Code) or for a reverse takeover (as defined in the Code); or

iv.) where the Panel on Takeovers and Mergers has determined that there has been a material change of circumstances.

The Company also confirms that with effect from the date of this announcement, G.P. (Jersey) Limited has been released from its obligations under the irrevocable undertaking that it entered into on 16 January 2022 in favour of the Company in relation to the shares that it held in Angus.

The Company further confirms that with effect from the date of this announcement, the letters of intent provided by each of Sebastian Marr, Niall Roberts, Martin Lang, Jacqueline Lang and Clive Roberts on 16 January 2022 in favour of the Company in relation to shares that it held in Angus have fallen away.
