Union Jack Oil plc

("Union Jack" or the "Company")

Cancellation of General Meeting

Union Jack Oil plc (AIM: UJO), a UK and USA focused onshore hydrocarbon production, development and exploration company, announces that following the receipt of proxies, it has become evident that there are insufficient votes in favour of the resolution to be put to shareholders at the General Meeting, due to be held on 30 October 2025 at 11:00 a.m. ("GM") and therefore the Directors have decided to withdraw the resolution and, accordingly, to cancel the GM.

At the proxy voting deadline yesterday, a total of 40,194,574 votes had been received from shareholders in connection with the resolution. Of these votes, approximately 21,098,060, representing approximately 13.8% of the Company's issued share capital are in favour of the resolution and approximately 19,096,514, representing approximately 12.49% are against the resolution. As is it unlikely that the special resolution will pass, the Board have decided to cancel the GM.

The Board remains of the view that it would be in the interests of all shareholders in the Company to share in its future growth and success, but has noted the views of shareholders regarding the resolution put forward. The Board remains open to constructive engagement with shareholders.
