Notice of AGM

Eco (Atlantic) Oil & Gas Ltd. (AIM: ECO, TSX ‐ V: EOG), the oil and gas exploration company focused on the offshore Atlantic Margins, announces that the Annual and Special Meeting of the Company ("AGM") will be held on 27 March 2026 at 10:00 a.m. (EST) at 217 Queen Street West, Suite 401, Toronto, Ontario, M5R 0V2. Copies of the formal notice of AGM and form of proxy will be made available on the Company's website at: https://www.ecooilandgas.com/investors/documents-circulars/

Following the recent corporate and business developments, the Board is taking the opportunity to propose a reduction in its size from nine members to five, to enable a more efficient and streamlined corporate governance and oversight of the Company's activities and to reflect the Company's stage of development.

Accordingly, subject to approval at the forthcoming AGM, the Board will be reduced in number to five directors. It is intended that Alice Carroll, VP Business Development, and Corporate Affairs and Chief Financial Officer Gadi Levin will step down from the Board and continue in their senior executive roles at the Company, and Mrs. Selma Usiku will retire from the Board but continue to serve on behalf of the Company as Vice Chairman of NAMPOA (Namibia Petroleum Operators Association). Accordingly, the aforementioned Directors have not put themselves forward for re-election at the shareholder meeting.

If the proposed resolutions are approved at the AGM, it is expected that the Board will comprise Keith Hill, Peter Nicol, Alan Friedman, and Emily Ferguson as Non-Executive Directors (one of whom will be elected Non-Executive Chairman), and Gil Holzman as Director, President & Chief Executive Officer. A further announcement will be made at that time.
