Dr Arron Tolley, Chief Executive Officer, commented:

"Yesterday's interim results confirm the cash position of £1.5 million at 31 December 2025 and the runway to Q2 2027 that we previously communicated. We are delighted with the strong support we have received in this Fundraise, including from a number of new investors who share our vision for the Optimer® platform. With this strong foundation now validated, the £4.275 million we have raised today is primarily for growth. A small portion will be allocated to working capital, materially extending our runway to 2028 and providing a clear pathway towards EBITDA breakeven. The majority of the funds will accelerate our two highest-potential opportunities: the development of our AI model focused on RNA-binding proteins and transcription factors, and the generation of key in-vivo animal data for the targeted radiopharmaceutical programme. These investments will drive the next phase of commercial value creation from the Optimer® platform."

The 536,666,668 Placing Shares comprise 230,083,333 Firm Placing Shares which have been issued and allotted under the existing authorities to issue shares and conditional on First Admission and are expected to be admitted to trading on AIM on around 31 March 2026, and 306,583,333 Conditional Placing Shares which will be allotted and issued conditional upon the passing of the Resolutions at the General Meeting expected to be convened for 13 April 2026 .  The issue of the Subscription Shares is also conditional upon the passing of the Resolutions at the General Meeting expected to be convened for 13 April 2026.  Assuming the Resolutions are passed, admission of the Conditional Placing Shares and Subscription Shares to trading on AIM is expected on or around 16 April 2026.

Participants in the Placing and Subscription will receive one Warrant to subscribe for new Ordinary Shares for every three new Ordinary Shares subscribed for in the Placing and Subscription with an exercise price of 0.9 pence per share (being a 50% premium to the Issue Price) at any time in the two years following the date of grant.
