Announcement of Changes in Management TOKYO, March 23, 2022 – Based on a resolution of the Board of Directors, Monex Group, Inc. (“the Company”) hereby announces the appointment of COO and CFO Yuko Seimei as co-CEO as well as the changes in officers, executive officers and an expert director. At the same time, the Company announces changes in management and employee for the following group companies. All appointments are effective April 1, 2022. – Monex Group, Inc. – Monex, Inc. – Monex Asset Management, Inc. 1. Background Ever since its founding 1999, the Company has played a pivotal role in the creation and development of Japan’s online brokerage business for individual investors. With the acquisition of the US online brokerage company TradeStation Group, the establishment of Monex Asset Management, Inc. and Japan Catalyst, Inc., and the 2018 acquisition of Coincheck, Inc., the Company now has a business portfolio with three pillars of operations – a global online brokerage business, an asset-management business and a crypto asset business. As announced in the press release dated March 22, 2022, “Coincheck Group B.V. to become public on the Nasdaq through a De-SPAC with Thunder Bridge Capital Partners IV, Inc.”, the Company aims to globalize its crypto asset business and increase profitability of the entire Group by making Coincheck Group B.V. into public in the United States. To secure the success of this strategy, the Company’s CEO Oki Matsumoto will focus considerable resources and energy to this project harnessing his 22 years of experience leading a publicly listed company and his extensive network in the global capital markets. Ever since current Representative Director Yuko Seimei joined the Company, she has played a pivotal role in establishing the investment business and successfully executed the Coincheck acquisition. She has also demonstrated exceptional management skills as president of Monex, Inc., and has records of accomplishment of executing businesses as COO/CFO of the listed company. In recognition of her leadership qualities, strategic thinking, and ability of managing human resources, Yuko Seimei has been appointed as co-CEO while continuing to serve as CFO. With the De-SPAC ushering the crypto asset business’s second phase of growth, the Company has decided to split the role of CEO into two functions. Oki Matsumoto, as CEO, will lead the crypto asset business and new businesses and oversee the asset management business, while Yuko Seimei will manage the global online brokerage business as co-CEO. To reinforce the areas of wealth management, asset management and technology, the Company has also decided to implement changes in executive officers. This new management team will work together to realize medium- and long-term business growth, greater corporate value and an increase in share price. 2. Changes in Management I. Monex Group, Inc.
