EXPLANATORY NOTE

This Post-Effective Amendment No. 1 filed by Woori Financial Group Inc., or the Registrant, a corporation organized under the laws of the Republic of Korea, relates to the Registration Statement on Form F-4 of Woori Bank (Registration No. 333-226345) and is being filed by the Registrant in order to adopt such Registration Statement as its own for all purposes under the U.S. Securities Act of 1933, as amended, or the Securities Act. Such Registration Statement, which was declared effective on November 13, 2018, was filed by Woori Bank on behalf of the Registrant to register the offering of the Registrant’s common stock to Woori Bank’s shareholders under the Securities Act in connection with a meeting of such shareholders held on December 28, 2018 to approve a “comprehensive stock transfer” under Article 360-15 of the Korean Commercial Code, or the Stock Transfer. In the Stock Transfer, which was effected as of January 11, 2019, holders of Woori Bank common stock transferred all of their shares to the Registrant, which was established simultaneously with such transfer, and in return received shares of the Registrant’s common stock. The Stock Transfer was effected to establish the Registrant as the financial holding company of Woori Bank, which became a wholly-owned subsidiary of the Registrant.
