Independent Auditor

Within the framework of independent audit agreement executed between our Company and Güney Bağımsız Denetim Ve Serbest Muhasebeci Mali Müşavirlik A.Ş. (Ernst & Young) for year 2025, Ernst & Young is conducting audits for consolidated financial statements. The independent audit report is submitted to Public Disclosure Platform (KAP) within the statutory period set for this purpose and published on the website and in the annual report of our Company.

In accordance with the regulations set by the Capital Markets Board (CMB) and the Public Oversight, Accounting and Auditing Standards Authority (POA), a mandatory audit firm rotation policy is implemented in Türkiye to ensure independence and objectivity. Within this scope, an audit firm is permitted to audit a company for 7 years out of a 10-year period. Once this term expires, the company is required to change its external auditor and cannot re-engage the same audit firm for at least 3 years. As Türk Telekom, we strictly manage our processes in compliance with these regulations.
