Exercise of Warrants

Borders & Southern Petroleum plc (AIM: BOR), the London based independent oil and gas exploration company with appraisal and exploration assets offshore the Falkland Islands, announces that it has received notification from a warrant holder to exercise warrants over 251,600 new ordinary shares of 1 pence each in the capital of the Company ("Warrant Shares") at the exercise price of 10 pence per Warrant Share, for an aggregate cash value of £25,160.

Application has been made for admission of the Warrant Shares to trading on AIM ("Admission") and it is expected that Admission will occur on or around 22 September 2026. The Warrant Shares will rank pari passu with the existing ordinary shares of 1 pence each in the capital of the Company (“Ordinary Shares”).

The balance of the warrants expire on September 21 unless exercised before that date.

Total Voting Rights

Following Admission, the total issued share capital of the Company will consist of 886,571,382 Ordinary Shares with voting rights. The Company does not hold any Ordinary Shares in treasury. Therefore, the total number of voting rights in the Company will be 886,571,382 and this is the 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 a change in their interest in, the share capital of the Company under the FCA's Disclosure Guidance and Transparency Rules.
