To: Target Companies

Japan Securities Co., Ltd (JSI) would like to send our best regards to your company.

Our company is 100% owned by Aizawa Securities Co., Ltd. This is a company with more than 100 years of history in the securities industry in Japan. In Vietnam, Aizawa Securities has been an investment bridge for tens of thousands of individual investors in Japan into the Vietnamese stock market since 2009.

On behalf of our parent company, Japan Securities Co., Ltd would like to inform you of the following:

In order to better meet the requirements of corporate governance and comply with the regulations of the Tokyo Stock Exchange, Aizawa Securities will carry out a plan to restructure the company to operate in the form of a parent-subsidiary company. Accordingly, Aizawa Securities will transfer all securities business activities to its subsidiary from October 1, 2021. This subsidiary, established in April 2021, will be the unit that directly conducts securities transactions on the Vietnamese stock market.

Currently Aizawa Securities is in the process of transferring the securities portfolio in the Vietnam stock market on its brokerage account to its subsidiary to take over.

Japan Securities Co., Ltd. would like to inform you that the transfer of this securities portfolio on the customer brokerage account of Aizawa Securities Co., Ltd to its subsidiary will not lead to any change in the foreign ownership percentage of your shares and will not change the threshold for information disclosure and public tender offer.

Yours sincerely!
