**Announcement Regarding the Result of ICTA Tender**

Our Company has been awarded a total frequency band of 160 MHz for USD 1,224 million (excluding VAT), valid until December 31, 2042, in the 5G spectrum allocation tender held today by the Information and Communication Technologies Authority ("ICTA") within the scope of the "Authorization for the Deployment and Operation of Mobile Electronic Communication Infrastructures and the Provision of Related Services, and the Inclusion of Infrastructures and Services under Existing Authorizations Expiring on April 30, 2029, within the Scope of This Authorization". The frequency payment will be made in three equal installments on January 2, 2026, December 25, 2026, and May 2, 2027.

As a result of this tender, Turkcell has obtained the right to utilize 394.4 MHz out of the total 949.2 MHz frequency resources available for use in Türkiye, corresponding to approximately 42% of the total frequencies. As in 4.5G, Turkcell has achieved the widest frequency portfolio in 5G, positioning itself as the operator technically capable of delivering the highest 5G speeds in Türkiye. With this strong spectrum advantage, Turkcell will reinforce its industry leadership by providing Turkey's highest 5G capacity.

With this tender, Turkcell has obtained the right to extend the validity period of its existing authorizations (2G, 3G, and 4.5G) until December 31, 2042. Within this scope, during the period between April 30, 2029, and December 31, 2042, each year, 5% of gross sales revenues (excluding VAT) from mobile services will be paid to the ICTA.

The 5G technology is planned to be launched for our customers starting from April 1, 2026.

The table below summarizes the frequencies which Turkcell has been awarded in the 5G tender and corresponding tender prices. The tender will be finalized following the completion of legal requirements, and the tender price will be paid through internal resources and various financing alternatives.
