Kookmin Bank’s Board of Directors Resolves to Apply for Preliminary Authorization Regarding Establishment of Financial Holding Company

Kookmin Bank (the “Bank”) disclosed that its Board of Directors, in a meeting on March 20, 2008, resolved to apply for preliminary authorization regarding the proposed establishment of a financial holding company, tentatively to be called KB Financial Group Co., Ltd. The draft preliminary authorization application approved by the Board of Directors of the Bank includes discussion on significant current matters and a three-year future business plan for KB Financial Group. Subject to the required domestic and overseas processes (including preliminary authorization from the Financial Services Commission) proceeding as planned, and upon the final approval of the Financial Services Commission, it is anticipated that KB Financial Group will be established in September 2008 as the fifth financial holding company to be established in Korea.

KB Financial Group is expected to have eight subsidiaries, including Kookmin Bank, KB Real Estate Trusts, KB Investment, KB Credit Information, KB Data System, KB Asset Management, KB Futures, and KB Investment & Securities, upon its establishment.

Prior to filing the preliminary authorization application, the Bank launched KB Investment & Securities (formerly Hannuri Investment & Securities) on March 11, 2008 and entered the securities business as part of the Bank’s efforts to spur its growth as a comprehensive financial services provider through the enhancement of its non-banking portfolio.

Meanwhile, the Bank plans to explore a spin-off of its credit card division within one year from the establishment of KB Financial Group, with the aim of providing a new platform for growth of its credit card business and to enhance the non-banking portfolio and to maximize synergies of the KB Financial Group.

The Bank further states that KB Financial Group aims to establish an infrastructure to maximize synergies, reinforce the Bank’s core competencies, transform into comprehensive financial services provider and expand its overseas business, in order to achieve value growth as a global financial group and to present an optimal operating model of a financial holding company.
