Clontarf Energy plc

("Clontarf" or "the Company")

Result of AGM and Capital Reorganisation

The directors of Clontarf Energy plc (AIM:CLON) announce that at the Annual General Meeting of the Company held earlier today (the "AGM"), all resolutions put to shareholders were duly passed.

The full text of the resolutions can be found in the Notice of the Annual General Meeting contained in the Company's Annual Report for the year ended 31 December 2021 (the "Annual Report") which was posted to shareholders on 29 June 2022 and is available on the Company's website at https://clontarfenergy.com/.

Capital Reorganisation

At the AGM, shareholders approved the Capital Reorganisation, as detailed in the Annual Report.

The Capital Reorganisation consists of each of the 2,370,826,117 issued ordinary shares of 0.25 pence each in the capital of the Company ("Existing Ordinary Shares") and any unissued ordinary shares of 0.25 pence each in the capital of the Company being subdivided into one new Ordinary Share of 0.01 pence each ("New Ordinary Shares") and one deferred share of 0.24 pence each ("Deferred Shares") on the basis of one New Ordinary Share and one Deferred Share for each Existing Ordinary Share.

Following the Capital Reorganisation, the Company will have a single class of ordinary shares of 0.01 pence each, being the New Ordinary Shares.

Admission of the New Ordinary Shares to trading on AIM

Application has been made to the London Stock Exchange plc for the admission to trading on AIM of the New Ordinary Shares, which is expected to become effective and dealings commence at 8.00 a.m. on or around 5 August 2022 (the "Reorganisation Admission").

Total voting rights, ISIN, SEDOL and par value

Pursuant to the Capital Reorganisation, the New Ordinary Shares will have the same ISIN, SEDOL code and number of total voting rights as the Existing Ordinary Shares.

Accordingly, upon the Reorganisation Admission, the Company's issued share capital will consist of 2,370,826,117 New Ordinary Shares each with one voting right. The Company does not hold any ordinary shares in treasury. This figure may be used by shareholders in the Company as the denominator for the calculation by which they may determine if they are required to notify their interest in, or change to their interest in, the share capital of the Company under the FCA's Disclosure Guidance and Transparency Rules. In addition, the ISIN and SEDOL code of the New Ordinary Shares remains the same as for the Existing Ordinary Shares, being GB00B09WLX62 and B09WLX6, respectively.

Unless otherwise defined, capitalised terms in this announcement have the same meanings as in the Annual Report sent to shareholders dated 29 June 2022.
