("Lansdowne" or the "Company")

Result of WRAP Retail Offer

Lansdowne Oil & Gas plc (AIM: LOGP) is pleased to confirm, further to the announcements made on 5 May 2026, the result of its Fundraise at the Issue Price of 0.1 pence per share. The Company announces that it has raised aggregate gross proceeds of £99,259 pursuant to the WRAP Retail Offer, alongside the previously announced Placing. Accordingly, the Company will issue a total of 99,259,000 new Ordinary Shares at the Issue Price pursuant to the WRAP Retail Offer.

In total, the Placing and the WRAP Retail Offer have raised gross proceeds of £1,999,259 for the Company, via the Placing of 1,900,000,000 Placing Shares and the 99,259,000 WRAP Retail Offer Shares.

Admission and Total Voting Rights

The issue of the Retail Offer Shares is conditional upon, inter alia, the passing of certain resolutions to be put to shareholders of Lansdowne Oil & Gas at the Annual General Meeting, which is expected to be held at  Howard Kennedy LLP, 1 London Bridge, London, SE1 9BG at 11.00 a.m. on 26 May 2026 Admission of the Retail Offer Shares is expected to occur no later than 8.00 a.m. on or around 27 May 2026.

Upon Admission, the Company's issued ordinary share capital will consist of 2,638,982,667 Ordinary Shares with one voting right each. The Company does not hold any Ordinary Shares in treasury. Therefore, from Admission the total number of Ordinary Shares and voting rights in the Company will be 2,638,982,667. With effect from Admission, this figure may be used by Shareholders in the Company as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the Company under the FCA's Disclosure Guidance and Transparency Rules.

The new Ordinary Shares to be issued pursuant to the WRAP Retail Offer will be issued free of all liens, charges and encumbrances and will, on Admission, rank pari passu in all respects with the new Ordinary Shares to be issued pursuant to the Placing, the Subscription and the Company's existing Ordinary Shares.
