The Company will also be issuing a further 137,145,481 Angus Energy Ordinary Shares (together, the "Deferred Consideration Shares") in relation to accrued interest until 31 December 2024.

The new shares will rank pari passu with the Company's existing shares and application has been made for the Deferred Consideration Shares to be admitted to trading on AIM ("Admission"). It is expected that Admission will become effective and dealings in the Deferred Consideration Shares will commence at 8:00 am on or around 24 March 2025.

Paul Forrest, on behalf of Forum said "as a committed shareholder, this conversion reflects our confidence in the Company's future and its continued growth potential. This is a long-term commitment, and we look forward to the Company returning value to us all."

For the purposes of the FCA's Disclosure and Transparency Rules ("DTRs"), following Admission of the new Ordinary Shares, the total issued share capital of the Company will consist of 4,986,893,414 Ordinary Shares, each with equal voting rights.
