("Diaceutics" or the "Company")

Belfast and London, 25 October 2024 - Diaceutics PLC (AIM: DXRX), a leading technology and solutions provider to the pharma and biotech industry, announces the issue of 773,777 share options over ordinary shares of £0.002 each in the Company ("Share Options") to certain directors and a member of the Company's senior management team, pursuant to the Company's Employee Share Option Plan ("ESOP").

The Share Options were granted as follows:

Ryan Keeling (CEO) & Nick Roberts (CFO)

557,953 Share Options were granted to Ryan Keeling and 139,488 Share Options to Nick Roberts on 24 October 2024. These Share Options are granted over the balance of ordinary shares held in the Company's Employee Benefit Trust ("EBT") which have not been utilised to satisfy other employee share options at the time of exercise and are therefore non-dilutive to shareholders. The shares held by the EBT were originally gifted by Peter Keeling (Non-Executive Chairman and a co-founder) to the EBT pre-IPO with intention that the shares be used to incentivise directors and employees of the Company.

The Share Options will vest in full upon the satisfaction of certain shareholder value performance criteria over the performance period, being five years from the date of grant. The performance criteria are based upon growth in Total Shareholder Return ("TSR") during the performance period, the successful sole or joint listing of the Company on an alternative public stock exchange and other customary corporate events. The exercise price of the Share Options is £0.002 per share which equates to the nominal value of the ordinary shares.

The Share Options are granted over the balance of ordinary shares outstanding in the EBT at the point of exercise and may change depending on the number of outstanding ordinary shares in the EBT at that time.

Subsequent to the grant of the above Share Options, Ryan Keeling has 1,139,900 shares under option which represents 1.35% of the existing issued share capital of the Company and Nick Roberts has 467,110 shares under option which represents 0.55% of the existing issued share capital of the Company.

Sandra Blake, Chief People Officer (CPO)

76,336 Share Options were granted to Sandra Blake, a Person Discharging Managerial Responsibilities ('PDMR'), on 22 October 2024. The Share Options vest on a sliding scale up to 100%, during the performance period from the date of grant to 27 July 2027, subject to the satisfaction of certain performance criteria. The performance criteria are based upon the growth during the performance period in TSR, the revenue Compound Annual Growth Rate ("CAGR") and recurring revenue. The exercise price of the Share Options is £0.002 per share which equates to the nominal value of the ordinary shares. Subsequent to the grant, Sandra Blake has 76,336 shares under option which represents 0.09% of the existing issued share capital of the Company.

These awards are made in accordance with the Company's long term incentive plan as detailed in the Company's Annual Report.

Following this grant, the total number of share options outstanding in the Company is 5,168,180 representing approximately 6.10% of its current issued share capital of 84,726,935.
