SDTTR/SDT UZAY VE SAVUNMA TEKNOLOJILERI A.S.

In accordance with the Capital Markets Board's (CMB) decision dated January 25, 2024, and numbered 6/121, SDT Uzay ve Savunma Teknolojileri A.Ş. has been classified under Group 1. As a result of this classification, and in compliance with CMB regulations, the Company is obligated to appoint a full-time Investor Relations Department Manager who holds both the "Capital Market Activities Advanced Level License" and the "Corporate Governance Rating Specialist License." Furthermore, pursuant to Article 23 of the Communiqué on Material Events, the Board may, if deemed necessary, require disclosures to be made in languages other than Turkish, considering factors such as the market in which the Company is listed, the group under which the Company is classified according to the Board's corporate governance principles, or any other criteria considered relevant by the Board.

Pursuant to this provision, the Material Events Guideline mandates that "In line with the Board's corporate governance regulations, companies classified in Group 1 are required to disclose material events simultaneously in both Turkish and English, with the responsibility for the accuracy of the content resting solely with the respective company." In this regard, a search for qualified personnel was undertaken. However, it became clear that the appointment could not be finalized within the maximum time frame required for the appointment of full-time personnel, as specified in Article 11/2 of the Corporate Governance Communiqué. Consequently, the Company has formally requested an extension from the Capital Markets Board (CMB).

During the recruitment process for qualified personnel, and in accordance with standard practice, the core responsibilities of the Investor Relations Department were temporarily undertaken by Emel KOÇAK. Ms. Koçak, who possesses all requisite licenses and qualifications, has been performing these duties on a part-time basis in coordination with the Accounting Department to ensure the uninterrupted operation of the department. Following Ms. Koçak's resignation from her part-time position in the Investor Relations Department, effective November 29, 2024, the essential functions of the department will be assumed by the Accounting Department until a full-time appointment is made.

This announcement is made to inform the public accordingly.

This statement has been translated into English for informational purposes. In case of a discrepancy between the Turkish and the English versions of this disclosure statement, the Turkish version shall prevail.
