Agenda of the Extraordinary General Meeting of Shareholders

1. Approval of the new edition of the Corporate Governance Code of the National Atomic Company "Kazatomprom" Joint Stock Company.

In order to further improve corporate governance, the Company has developed a new edition of the Corporate Governance Code ("the Code"), which reflects best corporate governance practices and mirrors the updated Corporate Governance Code of the majority shareholder - Samruk-Kazyna JSC ("the Fund"). The key new provisions of the Code include introduction of a competitive selection process for independent directors, gender quota for the Company's governing bodies, principles aimed at further reduction of the Fund's involvement in the Company's operations, and other amendments aimed at bringing the current edition of the Code up to date.

The Code in its new edition was preliminary approved by the decision of the Company's Board of Directors No. 9/25 dated 8 October 2025. Given that this issue falls within the exclusive competence of the Company's shareholders, it is proposed for the Meeting to approve the Code in a new edition and to declare invalid the currently effective Code (approved by the decision of the Fund No. 22/15 dated 27 May 2015).

Materials for the Meeting according to the agenda will be available to shareholders no later than 10 days before the date of the Meeting, at the Company's headquarters in accordance with clause 4 of Article 44 of the Law "On Joint Stock Companies". Upon request, physical copies of the Meeting materials will be sent within 3 business days of receipt of the request, with the costs related to compilation and delivery of the documents being borne by the shareholder. Requests from the shareholders of the Company must be received at the actual address of the Company, in the way prescribed by the legislation of the Republic of Kazakhstan.
