("Allergy Therapeutics" or the "Company")

Results of General Meeting and Posting of Annual Report 2025

29 December 2025 - Allergy Therapeutics plc (AIM: AGY), the fully integrated commercial biotechnology company specialising in allergy immunotherapies, announces that at the General Meeting held today, all resolutions were duly passed.

Results of General Meeting

All resolutions at the General Meeting were voted on by way of a poll. The results of the poll were as follows:

The General Meeting was held as the Board is considering potentially undertaking an equity raise which would be structured by issuing New Shares to new investors and/or existing shareholders in the Company for cash consideration in one or more private placements on a non-pre-emptive basis (the "Potential Equity Raise").

In order to facilitate the Potential Equity Raise and to ensure that it could be swiftly concluded if it progresses, the Board sought and, at the General Meeting, obtained, shareholder approval for the allotment and issue of up to 610,000,000 ordinary shares of £0.001 each ("New Shares") (which is approximately 10% of the Company's current issued share capital) on terms that the Board may determine. In order for the Directors to issue New Shares free of statutory pre-emption rights, such statutory pre-emption rights must be dis-applied. Accordingly, the Board sought, and, at the General Meeting, obtained, shareholder approval to dis-apply pre-emption rights in respect of the allotment of the New Shares pursuant to the Potential Equity Raise.

At this time, there is no certainty that the Potential Equity Raise will proceed and at this point no investors have entered into any agreements to subscribe for New Shares and the amounts and price of any Potential Equity Raise have not been agreed. To the extent that any money is raised from the Potential Equity Raise, it would be applied towards the Company's stated strategy of developing treatments for grass and peanut allergy patients, and general corporate purposes, including the Company's working capital needs prior to its anticipated dual listing on the Hong Kong Stock Exchange.

The Directors shall have discretion to determine the terms of the Potential Equity Raise, including the number of New Shares to be issued (subject to the limits of the authorities) and the price at which the New Shares will be issued, as well as the identity of who the New Shares will be issued to. Further details of the Potential Equity Raise (if it proceeds) will be announced in due course.

Posting of Annual Report

The Company also announces that it has posted to shareholders the Annual Report and Accounts for the year ended 30 June 2025. The Annual Report and Accounts are available to download from the Company's website at www.allergytherapeutics.com.
