Allergy Therapeutics plc ("Allergy Therapeutics" or the "Company")
Company to Evaluate Dual Listing on HKEX
Worthing, UK - 6 November 2025: Allergy Therapeutics plc, the fully integrated commercial biotechnology company specialising in allergy immunotherapies, announces that it is exploring a dual primary listing of its ordinary shares on the Main Board of The Stock Exchange of Hong Kong Limited ("HKEX").
This potential listing in Hong Kong, alongside the Company's existing listing on the London Stock Exchange's AIM market, reflects Allergy Therapeutics' desire to expand its presence in Asia and become a global leader in allergy treatments, while also enhancing trading liquidity in its ordinary shares. The Board believes that an HKEX listing and an associated equity offering would broaden the Company's investor base to include Hong Kong and mainland Chinese investors, aligning with the Company's growth ambitions in the region.
Preparatory work to explore the possible dual listing is underway, and if the Company decides to proceed with these plans, it would be targeting the HKEX listing becoming effective during the course of the first half of 2026, depending on market conditions. An application for listing of the Company's shares on HKEX would be subject to review and approval by the HKEX and the Securities and Futures Commission of Hong Kong, and there is no guarantee that the Company will proceed with such listing application.
Manuel Llobet, CEO of Allergy Therapeutics, commented: "We believe that a dual listing in Hong Kong could be an important step forwards for the Company. This initiative aligns well with our Asia expansion strategy and our aim to become a truly global player in the allergy immunotherapy field. By establishing a presence on HKEX, we would be able to engage more directly with Asian investors and support our growth in Asian markets, which we see as a key driver for Allergy Therapeutics' future success."
Allergy Therapeutics will make further announcements as appropriate to keep the market informed of material developments.
