Announcement on the Publication of a New Information Document

O3 Partners N.V. (registered office: Netherlands, 3013 AK Rotterdam, Stationsplein 45, company registration number: 96066717, hereinafter the "Company") hereby informs its esteemed Investors of the following:

On 10 June 2025, the Company announced that the Board of Managing Directors decided on a capital increase in the amount of EUR 4.6 million, acting under the authorization granted by the General Meeting. According to the resolution, the parties participating in the capital increase are acquiring ordinary shares, which the Company is obliged to issue and have admitted to trading within the existing stock exchange listing.

In accordance with applicable Hungarian and EU regulations, as the number of new shares to be admitted to trading exceeds 20% of the securities already admitted to the same regulated market within a 12-month period, it has become necessary to update and publish the Company's Information Document in connection with this admission.

Accordingly, the Company has prepared a new Information Document, which was approved by the Market Operator, i.e. the Budapest Stock Exchange Plc., by its resolution No. 31/Xtend/2025 dated 6 November 2025. The new Information Document presents in detail the Company's activities, strategy, financial position, key risks and their management, as well as information on the management, ownership structure, and the main characteristics of the issued shares.

The approved Information Document is available on the Company's website, on the official disclosure platform of the Budapest Stock Exchange, and on the website of Central Bank of Hungary.
