Management Solutions Co. Ltd. (the Company) announced that its Board of Directors has informally decided at the Board of Directors meeting held on December 8, 2023, to change President & CEO. Approval on this matter will take place at the 19th Annual General Meeting of Shareholders on January 30, 2024, and at the Board of Directors meetings that follows the conclusion of the General Meeting of Shareholders.

Reason for the Change: In order to further promote realization of the vision set by group, the Company has decided to reform management structure. Akira Kaneko, who will be newly appointed as President and CEO, has expanded the Company's business as General Manager of the Project Management division before and after the company went public on the Tokyo Stock Exchange. Moreover, Akira Kaneko launched the PROEVER business as General Manager of the division, and expanded sales as Director of MSOL China, a subsidiary of the Company.

In mid-term business plan toward 2025, the company has built a strong organization to further expand profit-earning opportunities by launching a sales organization and turning to "Aggressive Sales Activities". In addition, a report by a major research firm indicates the potential market for PMO services is expected to be worth JPY 1 trillion by 2030. The company aims to further strengthen customer engagement, promote the development of potential markets, and expand its market share, and will take strong leadership based on Akira Kaneko's rich experience and achievements to firmly establish its steadfast position as a leading PMO company.

As Chairman of the Board, Shinya Takahashi, the current President and CEO, will continue to support the new President and CEO in order to continuously develop the management organization after 2025, strengthen communication for alliances and M&A, and engage in investor relations activities. Furthermore, Shinya Takahashi will utilize his extensive experience acquired as a consultant to address issues in East Asia and Japan beyond the scope of a single company, such as educational disparities and social welfare, through activities beyond the business scope of Management Solutions Co.
