Gloster Digital Group Public Limited Company (company registration number: 01-10-143270; registered office: 1038 Budapest, Fürdő u. 2.; hereinafter: Company) hereby informs investors of the following in accordance with the relevant legislation, in particular Act CXX of 2001 on the Capital Market (hereinafter: Tpt.), Decree 24/2008. (VIII. 15.) PM on the detailed rules of disclosure obligations relating to publicly traded securities, and the General Business Rules of the Budapest Stock Exchange, hereby informs its esteemed investors of the following.

During a subsequent audit, the Company determined that the extraordinary announcement published on October 14, 2025 incorrectly reported a change in the Company's treasury stock.

Accordingly, the Company corrects the published data as follows:

As a result of a share transaction (securities lending) by the Szekeres Viktor Asset Management Foundation, a legal entity closely related to Gloster's senior officer, the Company's portfolio of treasury shares increased by 219,648 ordinary shares, thus increasing Gloster's own shares to 1.25% of the total number of shares issued.
