Lansdowne Oil & Gas plc

("Lansdowne" or the "Company")

Energy Charter Treaty Claim Distribution Plan

· Record date of Registered Shareholders of the Company expected to be set as 21 March 2024 (date of Suspension)

· Registered Shareholders at the record date planned to be protected beneficiaries of the outcome of the Arbitration process

Further to the update provided on 26 February 2024, the Company is focused upon progressing its Energy Charter Treaty claim ("ECT Claim") against Ireland following the refusal to award a Lease Undertaking for the Barryroe oil and gas field ("Barryroe").

On 20 September 2023 Lansdowne announced that, under Rule 15 of the AIM Rules for Companies ("AIM Rules"), the Company had been designated to be a cash shell. Accordingly, given that the Company does not expect to undertake acquisition, or acquisitions, which constitutes a reverse takeover under Rule 14 of the AIM Rules ("Reverse Takeover") ahead of the six-month suspension window, the Company's shares will be suspended from trading on AIM as at 7.30 am on 21 March 2024 ("Suspension").

It is the intention of the Board of Directors that, in the event of a successful ECT claim outcome against Ireland by the Company and/or its subsidiary Lansdowne Celtic Sea Limited (together the "Claimants"), arrangements will be put in place in advance to ensure that qualifying shareholders will receive an economic benefit relating to their shareholding at the date of Suspension, ensuring that should there be any future changes in the capital structure of the Company, the impact on such shareholders vis a vis as beneficiaries of a successful ECT Claim, will be ring fenced.

The Board of Directors intend that such arrangements will account for all or a proportion of the net proceeds of a successful ECT Claim outcome (after deduction of the reasonable legal and ancillary costs associated with the ECT claim), including the use by the Company of potential proceeds from the ECT Claim as an asset, which may prove valuable for any future transactions including a Reverse Takeover. If the Company does complete a Reverse Takeover during the six-month period following Suspension, this would lead to the lifting of the Suspension.

It should be cautioned that there is no guarantee that the Claimants will be successful in the ECT Claim. Moreover, in the event the Barryroe licence is reinstated, potentially leading to the ECT Claim being subsequently withdrawn, the Company's full economic interest in Barryroe will remain with the Company.

The Company is taking further tax, legal and regulatory advice and will make further announcements as appropriate.

Steve Boldy, CEO of Lansdowne, commented:

'We believe the actions of the Irish Government are wholly inappropriate and the Company is therefore electing to preserve its interests under the Energy Charter Treaty. We believe it is only right for existing shareholders who have been disadvantaged by these actions from Ireland to have their position protected in the event of a successful outcome under the ECT Claim, notwithstanding the Suspension of trading in the Company's shares on AIM.

'In the meantime, Shareholders will also continue to benefit from the Company's interest in the potential outcome of the ECT Claim and we believe this, along with our AIM listing, will provide significant value for discussions with interested parties looking to undertake a Reverse Takeover.

'With a market capitalisation of less than £1 million and a likely claim under the ECT in excess of US$100 million, we believe the Company's interest in the outcome of the ECT Claim potentially offers shareholders a multiple increase in the current valuation in any discussions over future assets vended into the Company and constituting a Reverse Takeover which, in turn, would also see a lifting in the suspension of our shares on AIM.'
