TO: Investment Community

FROM : Garanti BBVA / Investor Relations

SUBJECT: Announcement regarding our Bank’s Corporate Governance Compliance Rating

DATE: December 09, 2022

Our Bank has signed an agreement with JCR Eurasia Rating, which is an authorized rating agency operating under the license of the Capital Markets Board of Turkey (“CMB”) in accordance with the Corporate Governance Principles issued by the CMB, on 14.07.2022 for a period of one year. As a result of JCR Eurasia Rating’s assessment for 2022, our Bank’s Corporate Governance compliance score has been increased to 9.81 from 9.79 (over 10) and the outlook has remained as Positive.

The rise in ‘Shareholders’ and ‘Stakeholders‘ sub-sections in 2022 has increased the Bank’s overall compliance score. Considering the positive contribution of the Board of Directors Diversity and Compliance Policy published on 08 July 2021 and the female representation target in the Board of Directors of 25% by the end of 2025, the outlook of the main section of the Board of Directors of the Bank is “Positive”.

The Bank managed to maintain high level of compliance previously attained in the main sections of Public Disclosure and Transparency and Board of Directors. The Bank's overall Corporate Governance Rating is determined, in compliance with the relevant regulations of the CMB, under the weighted four sub-sections. Compliance levels in each of the four main sections with comparison to the previous year are as below.

The Bank will remain to be within the scope of Borsa İstanbul Corporate Governance Index due to its overall corporate governance compliance score being higher than the threshold score of “7”. Corporate Governance Rating Report prepared by JCR Eurasia Rating is accessible on the Bank's Investor Relations website (www.garantibbvainvestorrelations.com).

*In contradiction between the Turkish and English versions of this public disclosure, the Turkish version shall prevail.

We declare that our above statements are in conformity with the principles included in the Board’s Communiqué, Serial II Nr.15.1, that it exactly reflects the information we received; that the information complies with our records, books and documents; that we did our best to obtain the correct and complete information relative to this subject and that we are responsible for the declarations made in this regard.

Yours sincerely,
