Sure. According to the Securities and Futures Ordinance of the Hong Kong Special Administrative Region, individuals and corporations (defined as major shareholders of listed corporations) who hold 5% or more of any class of voting shares for the first time (Hong Kong listed corporations can issue non-voting shares) must disclose relevant information:

1. Holding the rights and interests and short positions of the voting shares of listed companies.

2. Equity derivatives held by listed companies include equity derivatives held, sold or issued by major shareholders, as well as rights exercised, transferred or not exercised by major shareholders according to the derivatives, which may lead to the delivery of shares to holders or by holders to others.

3. The following changes in major shareholders' equity and short positions:

(1) The increase or decrease in the percentage of shares leads to the major shareholder's equity exceeding 5% (for example, if the major shareholder's equity increases from 6.8% to 7. 1%, that is, if it exceeds 7%, it is necessary to disclose its equity changes).

(2) The major shareholder holds the rights and interests to be declared, and the nature of the shares' rights and interests changes (such as exercising options).

(3) The major shareholder holds the rights and interests to be declared, and holds or no longer holds more than 65,438+0% short positions during the disclosure period (for example, the major shareholder has held 6.8% shares of a listed company and 65,438+0.9% short positions).

(4) The major shareholder holds the rights and interests to be declared, and the proportion of short positions increases or decreases, resulting in the percentage integer of the major shareholder's short positions exceeding 65,438+0% (for example, the major shareholder has already held 6.8% of the rights and interests of a listed company, and the short positions have increased from 65,438+0.9% to 2.65,438+0%).

The specific reporting time is within 3 working days from the date when the major shareholder knows the above events. When a major shareholder purchases shares, it shall generally issue a filing notice within 3 working days after the conclusion of the share purchase contract; After the shares are sold, the major shareholder usually needs to send a filing notice within 3 working days after the settlement date (that is, the date when the relevant shares are delivered to the buyer). However, the Securities and Futures Ordinance does not prohibit major shareholders from buying and selling shares of listed issuers within these three days.

The above can only briefly explain the relevant provisions of the Securities and Futures Ordinance of Hong Kong, and cannot describe all the situations in detail. Therefore, individual cases must depend on the circumstances.
