To the Shareholders,

Dear Sir or Madam,

PROPOSED CHANGE OF COMPANY NAME
AND
NOTICE OF SPECIAL GENERAL MEETING

INTRODUCTION

The purpose of this circular is to provide you with information regarding the resolution to be proposed at the Special General Meeting for the Proposed Change of Company Name and to give you notice of SGM.

---

LETTER FROM THE BOARD

PROPOSED CHANGE OF COMPANY NAME

The Board proposes to change the existing English name of the Company from "Japan Kyosei Group Company Limited" to "Vision Synergy Holdings Limited" and to adopt the Chinese name "共生智藥控股有限公司" as the new secondary name of the Company in place of the existing secondary name "日本共生集團有限公司".

REASONS FOR THE PROPOSED CHANGE OF COMPANY NAME

The Board considers the Proposed Change of Company Name will better reflect the direction of future development of the Company and therefore the Proposed Change of Company Name can provide the Company with enhanced corporate image and clearer identity. The Board is of the opinion that the Proposed Change of Company Name will benefit the Company's future business development and is in the best interests of the Company and the Shareholders as a whole.

CONDITIONS OF THE PROPOSED CHANGE OF COMPANY NAME

The Proposed Change of Company Name will be subject to the following conditions being fulfilled:

(i) the passing of a special resolution by the Shareholders approving the Proposed Change of Company Name at the SGM; and

(ii) the Registrar of Companies in Bermuda having approved the Proposed Change of Company Name.

Subject to the satisfaction of the conditions set out above, the Proposed Change of Company Name will take effect from the date the Registrar of Companies in Bermuda registers the new English name in place of the existing English name of the Company and registers the secondary name of the Company as set out in the certificate of incorporation on change of name and the certificate of secondary name to be issued by the Registrar of Companies in Bermuda. The Company will then carry out the necessary filing procedures with the Companies Registry in Hong Kong pursuant to Part 16 of the Companies Ordinance (Chapter 622 of the Laws of Hong Kong).

---

LETTER FROM THE BOARD

EFFECT OF THE PROPOSED CHANGE OF COMPANY NAME

The Proposed Change of Company Name will not affect any of the rights of the Shareholders or the Company's daily business operation or its financial position. Once the Proposed Change of Company Name becomes effective, new share certificates of the Company will be issued in the new name and the new secondary name of the Company. However, all existing share certificates in issue bearing the current name of the Company will, after the Proposed Change of Company Name has become effective, continue to be effective as documents of title and be valid for trading, settlement, registration and delivery purposes. Accordingly, there will not be any arrangement for exchange of the existing share certificates of the Company for new share certificates bearing the new name and the new secondary name of the Company.

Subject to the confirmation of the Stock Exchange, the Company expects to be traded in its new English name and new secondary name as soon as the Proposed Change of Company Name becomes effective and the filing procedures in Hong Kong have been completed. Further announcement(s) will be made by the Company to inform the Shareholders on the results of the SGM, the effective date of the Proposed Change of Company Name and the change of stock short names of the Company for trading of the shares on the Main Board of the Stock Exchange as and when appropriate.

GENERAL

The Proposed Change of Company Name is subject to, inter alia, the approval by the Shareholders by way of a special resolution at the SGM. To the best knowledge, information and belief of the Directors having made all reasonable enquiries, no Shareholder will be required to abstain from voting on the special resolution for approving the Proposed Change of Company Name.

SPECIAL GENERAL MEETING

The Company will convene the SGM at Room 1102, 11/F, Woon Lee Commercial Building, No. 7-9 Austin Avenue, Tsim Sha Tsui, Kowloon, Hong Kong on 9 October 2025 at 12:00 noon for the purpose of considering and, if thought fit, approving the resolution set out in the SGM Notice as set out on pages 8 to 9 of this circular.

A form of proxy for use at the SGM is enclosed with this circular. Such form of proxy is also published on the website of the Stock Exchange at www.hkexnews.hk and on the website of the Company at http://www.jkgc.com.hk. Whether or not you intend to attend the SGM in person, you are requested to complete and return the enclosed form of proxy in accordance with the instructions printed thereon to the Company's branch share registrar, Union Registrars Limited, at Suites 3301-04, 33/F., Two Chinachem Exchange

VOTING BY POLL

According to Rule 13.39(4) of the Listing Rules, any vote of Shareholders at a general meeting must be taken by poll except where the chairman of the meeting may in good faith, allow a resolution which relates purely to a procedural or administrative matter to be voted on by a show of hands. Therefore, the resolution(s) put to the vote at the SGM will be taken by way of poll. An announcement on the results of the vote by poll will be made by the Company after the SGM in the manner prescribed under Rules 13.39(5) and (5A) of the Listing Rules.

RESPONSIBILITY STATEMENT

This circular, for which the Directors collectively and individually accept full responsibility, includes particulars given in compliance with the Listing Rules for the purpose of giving information with regard to the Company. The Directors, having made all reasonable enquiries, confirm that to the best of their knowledge and belief, the information contained in this circular is accurate and complete in all material respects and not misleading or deceptive, and there are no other matters the omission of which would make any statement herein or this circular misleading.
