Extension of Share Buyback Programme

Origin Enterprises plc ("Origin" or the "Company") announces its decision to extend its existing share buyback programme of up to €20m (the "Share Buyback Programme"), originally due to expire on 29 July 2024, for a further two months to 30 September 2024 in order to allow the Share Buyback Programme to be completed. Save as set out herein, the Share Buyback Programme will otherwise operate under the same terms as previously announced on 20 November 2023.

The Share Buyback Programme may continue until 30 September 2024 subject to market conditions, the ongoing capital requirements of the business and termination provisions customary for arrangements of this nature.

The purpose of the Share Buyback Programme is to reduce the share capital of the Company. The repurchased ordinary shares will be held in treasury pending their cancellation or re-issue in due course. The maximum number of ordinary shares to be repurchased under the Share Buyback Programme is 11,203,198. Any repurchases will be carried out on Euronext Dublin.

Goodbody will continue to make its trading decisions in relation to the Company's shares independently of, and uninfluenced by, the Company and in accordance with certain pre-set parameters. The Share Buyback Programme will continue to be conducted: (i) in accordance with the Company's general authority to repurchase ordinary shares as approved by the shareholders at the Company's AGM on 16 November 2023; and (ii) the parameters prescribed by the Market Abuse Regulation 596/2014/EU, the Commission Delegated Regulation (EU) 2016/1052 and the applicable laws and regulations of Euronext Dublin.

The Share Buyback Programme may be supplemented by the purchase of ordinary shares by way of block trades effected by Goodbody as agent of the Company in accordance with the Company's general authority to repurchase shares. Any shares repurchased through block trades will count towards the maximum consideration payable, and the maximum number of shares that may be purchased, by the Company under the Share Buyback Programme.

Details of any ordinary shares repurchased under the Share Buyback Programme will be notified to a Regulatory Information Service by the Company following repurchase. The Company confirms that currently it has no unpublished inside information.
