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

DATE: December 06, 2024

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 12.07.2024 for a period of one year. As a result of JCR Eurasia Rating’s assessment for 2024, our Bank’s Corporate Governance compliance score has been increased to 9.82 from 9.81 (over 10) and the outlook has been revised as Stabil.

The level of compliance attained in the previous year across the main sections of Shareholders, Public Disclosure & Transparency and Stakeholders have been maintained. Compliance score of Board of Directors main section has been increased to 9.85 from 9.81 The main factor behind this increase is the exceeding of the 25% female member threshold specified in the Corporate Governance Principles with the appointment of Ms. Ebru Oğan Knottnerus as a member of the Board of Directors on 27 March 2024. Due to JCR-ER’s opinion that during the upcoming monitoring period following the publication date of this report Garanti BBVA will maintain its high level of compliance, both in the overall compliance rating and in the four main segment ratings. Therefore, the Bank's outlook rating has been determined as “Stable”.

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.
