PDMR Shareholding/Share Incentive Plan and Total Voting Rights

New York, Belfast and London, 6 June 2025 - Diaceutics PLC (AIM: DXRX), a leading technology and solutions provider to the pharma and biotech industry, has been notified that on 4 June 2025, Global Shares Trustees (UK) Limited (the "UK Trust") and Zedra Trust Company (Guernsey) Limited, the trustees of the Global Diaceutics plc 2020 Employee Benefit Trust, have purchased ordinary shares of £0.002 in the capital of the Company ("Shares") on behalf of Susanne Munksted, Jordan Clark, Nick Roberts and Jillian Beggs (PDMRs), in respect of their purchase of Shares pursuant to the Company's UK and Global Share Incentive Plan ("the SIP Schemes") for  employees. These purchases will be made each month until further notice.

In accordance with the SIP Schemes, the Company has matched these purchases with a matched share award over an equivalent number of Shares purchased by the employee, in the proportion of 1:1.

As announced on 2 October 2023, application was made to AIM for a block listing of 1,500,000 Shares to facilitate the admission of the Shares to trading following the exercise of options inter alia under the SIP Schemes. Therefore, the matched share awards for the UK PDMRs, along with those for all other participants in the UK SIP Scheme, have been settled by the Company through unallocated Shares which have been previously issued to and are held by the SIP Schemes. The Trust will hold these Shares on behalf of participants until they vest in accordance with the UK Scheme rules.

Diaceutics has 84,805,079 Shares in issue. This figure may be used by shareholders in the Company as a 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.
