6 terms

WVR ordinary shares financial

"Class of shares | | WVR ordinary shares | | Type of shares"

public float financial

"Public float sufficiency confirmation (Note 4)"

Public float is the total number of a company's shares that are available for trading by the general public. It excludes shares held by company insiders or large stakeholders who are unlikely to sell them easily. This figure helps investors understand how much of the company's stock is actively available, which can influence its liquidity and how easily its price might change.

convertible senior notes financial

"2027 Notes - US$800 million convertible senior notes"

Convertible senior notes are a type of loan that a company issues to investors, which can be turned into company shares later on. They are called "senior" because they are paid back before other debts if the company runs into trouble. This allows investors to earn interest like a loan but also have the chance to own part of the company if its value rises.

Share Incentive Plan financial

"2018 Share Incentive Plan - options"

A share incentive plan is a company program that gives employees or directors the chance to receive or buy company shares, often after staying with the firm or meeting performance goals. It matters to investors because it’s like giving workers a slice of the company pie to boost performance and loyalty, but issuing those slices can reduce each existing owner’s portion and change metrics such as earnings per share and share count.

treasury shares financial

"Number of treasury shares | | Total number of issued shares"

Treasury shares are a company’s own stock that it has repurchased and keeps on its books instead of canceling or leaving in the hands of outside investors. Think of them like coupons a business puts back in a drawer: they don’t vote or receive dividends while held, but they can be reissued later for employee pay or fundraising. For investors this matters because buybacks change the number of shares that count toward earnings and ownership, can boost per‑share metrics, and use corporate cash that might otherwise go to growth or dividends.

restricted share units financial

"2018 Share Incentive Plan - restricted share units"

Restricted share units (RSUs) are a promise from a company to give an employee or service provider actual shares or cash equal to the shares after certain conditions are met, typically staying with the company for a set time or hitting performance targets. Think of them like a time-locked gift card that becomes usable only after you’ve earned it. For investors, RSUs matter because they align employee incentives with company performance and can increase the number of shares outstanding over time, diluting existing ownership and affecting earnings per share.

Notes

1. The Exchange refers to The Stock Exchange of Hong Kong Limited.

2. In the case of repurchase of shares (shares repurchased and cancelled) and redemption of shares (shares redeemed and cancelled), “date of event” should be construed as “cancellation date”.

In the case of repurchase of shares (shares held as treasury shares), “date of event” should be construed as “date on which shares were repurchased and held by the issuer in treasury”.

3. The information is required in the case of repurchase of shares (shares repurchased for cancellation but not yet cancelled) and redemption of shares (shares redeemed but not yet cancelled). Please state the number of shares repurchased or redeemed during the month or in preceding month(s) but pending cancellation as at close of the month as a negative number.

4. “Initial Prescribed Threshold”, “Alternative Threshold” and “market value” have the meanings ascribed thereto under Main Board Rule 13.32A or 19A.28A / GEM Rule 17.37A or 25.21A. See also Main Board Rule 13.32D(4) or 19A.28D(4) / GEM Rule 17.37D(4) or 25.21D(4) on the basis of the public float disclosure.

5. Items (i) to (viii) are suggested forms of confirmation. The listed issuer may amend the item(s) that is/are not applicable to meet individual cases. Where the issuer has already made the relevant confirmations in a return published under Main Board Rule 13.25A / GEM Rule 17.27A in relation to the securities issued, or the treasury shares sold or transferred, no further confirmation is required to be made in this return.

6. “Identical” means in this context:

• the securities are of the same nominal value with the same amount called up or paid up;

• they are entitled to dividend/interest at the same rate and for the same period, so that at the next ensuing distribution, the dividend/interest payable per unit will amount to exactly the same sum (gross and net); and

• they carry the same rights as to unrestricted transfer, attendance and voting at meetings and rank pari passu in all other respects.
