Consideration Shares to be Admitted to Trading

Further to yesterday's announcement regarding the acquisition of a 10 per cent. stake in the Sasanof Prospect, Clontarf announces that application has been made for 100,000,000 new ordinary shares of 0.25p each ("Ordinary Shares") (Consideration Shares") to be admitted to trading on AIM.  These Consideration Shares are part of the consideration payable to Western Gas for the stake in the Sasanof Prospect and, when admitted, will rank pari passu with the Company's existing Ordinary Shares. It is expected that such admission will become effective on or around 13^th May 2022.

Following the admission of the Consideration Shares, there will be a total of 2,370,826,117 Ordinary Shares in issue with each share carrying the right of one vote. The above figure may be used by shareholders as the denominator for the calculations by which they will determine if they are required to notify their interest in, or change to their interest in, the Company under the FCA's Disclosure Guidance and Transparency Rules.

This announcement contains inside information for the purposes of Article 7 of Regulation (EU) 596/2014.
