Changes to the Board of Directors

Jersey, Channel Islands, May 18, 2018 -- Serinus Energy plc ("Serinus", "SEN" or the "Company") (AIM:SENX, TSX:SEN, WSE:SEN), today announces that Mr. Dominik Libicki has resigned from the Board of Directors of the Company (the "Board") and Ms. Tracy Heck has been appointed to the Board.

Mr. Libicki's resignation is in accordance with the terms of the relationship deed between Kulczyk Investments SA ("KI"), the Company and Numis Securities Ltd. whereby KI has agreed to appoint a prescribed number of directors to the Board based upon requisite shareholding thresholds set out in the relationship deed. The recent equity raise has resulted in KI now holding 38.77% of the ordinary shares of the Company, precipitating the requirement that KI reduce the number of appointments to the Board from three to two.

Ms. Heck, Chief Financial Officer of the Company since 2014, is a Chartered Accountant, qualified in both England and Canada, with over 25 years of financial experience. She will be an executive director on the Board.

No further information regarding Ms Heck is required to be disclosed under Schedule 2(g) of the AIM Rules for Companies. Ms Heck holds no shares in the Company.

The Board expresses its profound gratitude to Mr. Libicki for his diligent years of service and welcomes Ms. Heck to the Board.
