SYMPHONY ENVIRONMENTAL TECHNOLOGIES PLC

("Symphony", the "Company" or the "Group")

Director/PDMR Shareholdings - Options amendments

Symphony Environmental Technologies Plc (AIM: SYM), global specialists in products and technologies that "make plastic and rubber products smarter, safer and more sustainable", announces an extension to the exercise period of options held by the directors of the Company (the "Directors") and certain other option holders.

The Company had previously granted options to purchase 10,191,500 ordinary shares of 1p each in the Company (the "Options") of which 8,441,500 were to certain directors of the Company. The exercise prices of the Options are 4.5 pence and 12.5 pence, so all the Options are below the prevailing price of the Company's ordinary shares. The Options were due to expire on 31 December 2023 but have been extended for practical reasons to 31 December 2024 ("Option Extension"). The Options represent 5.5% of the total issued share capital of the Company.

The extension of the Options granted to Directors is considered a related party transaction pursuant to the AIM rules for companies. Accordingly, the Directors except for the relevant director and the options awarded to him, consider, having consulted with the Company's nominated adviser, that the Option Extension is fair and reasonable insofar as the Company's shareholders are concerned.

See PDMR disclosure tables below for further information. All other terms of the Options remain the same.
