United Oil & Gas Plc (AIM: "UOG"), the oil and gas company with a high-impact exploration asset in Jamaica and a development asset in the UK, is pleased to announce the appointment of Donal Meehan as Chief Operating Officer (non-board appointment) effective immediately.

Donal previously served as United's Head of Commercial and brings over 20 years of upstream oil and gas experience across senior reservoir engineering, commercial and leadership positions. He began his career at ExxonMobil before joining Providence Resources plc, gaining extensive international experience across the full upstream lifecycle, from onshore production operations to deepwater frontier exploration.

He has led acquisitions and divestments, deepwater exploration programmes and complex commercial negotiations across Europe, the Caribbean, Africa and North America. His appointment reflects United's focus on ensuring the Company is operationally and commercially prepared as it advances the Walton-Morant farm-out process, while strengthening the management capability required to build and grow the business.

Donal is a former Chairperson of the Society of Petroleum Engineers ("SPE") Ireland Section and remains actively involved in industry development and technical excellence. He holds a First-Class Honours degree in Chemical Engineering from University College Dublin.

This appointment comes at a time when the Company prepares to enter a new phase in its development.

Brian Larkin, CEO, commented:

Donal's appointment as Chief Operating Officer further strengthens our management team and enhances United's operational readiness and commercial capability. It comes at an important time for the Company as we push to conclude the Jamaican farmout.

Donal has been instrumental in advancing our commercial strategy and brings a valuable combination of technical expertise, asset knowledge and transactional experience. His understanding of the Walton-Morant opportunity, together with his experience across deepwater exploration and commercial negotiations, will be important as we continue to progress the farm-out, and build United into a stronger and broader business.

On behalf of the Board, I congratulate Donal on his appointment and wish him every success in his new role.

Donal Meehan, COO, commented:

"I am pleased to step up into the role at an important time for the Company. My immediate focus will be on continuing to advance the Walton-Morant farm-out process, ensuring operational readiness and progressing the Licence into its next phase.

I'm excited for the company and look forward to contributing towards building the business."
