("N4 Pharma" or the "Company")

Notice of General Meeting and Proposed Change of Name to Thalia Therapeutics plc

N4 Pharma plc (AIM: N4P), the UK biotech developing Nuvec®, its proprietary gene delivery system to enable advanced therapies for cancer and other diseases, announces its intention to change its name to Thalia Therapeutics plc, subject to approval by its shareholders at a general meeting of the Company (the "General Meeting") to be held on Tuesday, 17 March 2026 at 10.00 am at the offices of Arch Law Limited Huckletree Bishopsgate, 8 Bishopsgate, London, EC2N 4BQ.

The proposed change of name reflects the Company's recently announced transition to a therapeutic biotechnology business focused on the development of innovative, high-value RNA-based therapeutics, alongside the continued advancement of its proprietary Nuvec® delivery platform. As outlined in the Company's announcement of 24 February 2026, the Board believes that the name Thalia Therapeutics plc more accurately represents the Company's expanded pipeline, new leadership and clear strategic direction as it advances internally generated RNA assets and pursues partnering opportunities to create long-term shareholder value.

The proposed change of name is subject to shareholder approval and the issue of a change of name certificate by Companies House. The Company's TIDM will be THAT, and its LEI, ISIN and SEDOL will remain unchanged. Existing share certificates will remain valid, and no new certificates will be issued.

Following registration of the change of name, the Company's website (containing the information required by AIM Rule 26) will be updated to reflect the new name, with further details announced at that time.

The proposed name change will be presented as a special resolution at the General Meeting. Details of the General meeting, including the time and venue, will be included in the Notice of General Meeting alongside a form of proxy, which has been dispatched to shareholders and made available on the Company's website at: https://investors.thaliatx.com/aim-rule-26
