Extension of Warrant Expiry Dates

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, announces that it has agreed to extend the expiry dates of two existing sets of warrants currently in issue.

Details of the warrant extensions are as follows:

a) Approximately 166,666,667 warrants with an exercise price of £0.0028 per ordinary share, originally issued on 20 March 2024 and due to expire on 31 December 2025, will now expire on 24 April 2026.

b) Approximately 320,000,000 warrants with an exercise price of £0.0015 per ordinary share, originally issued on 9 January 2025 and due to expire on 31 December 2025, will now expire on 24 April 2026.

All other terms of the warrants remain unchanged.

The extensions are intended to ensure that the warrants remain aligned with the Company's anticipated near-term operational milestones, including the upcoming piston coring survey offshore Jamaica, where results are expected in early Q1 2026.

The Company expects to provide a further update once the survey vessel mobilises for United's programme.
