Restricted Share Units financial

"These restricted share units (the "RSUs") are expected to vest in eight installments"

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.

American Depositary Share financial

"Represents American Depositary Share ("ADS") acquired upon the Vesting."

An American Depositary Share (ADS) is a U.S.-listed certificate that represents a specified number of shares in a foreign company, held by a custodian bank; it works like a receipt that allows U.S. investors to buy and trade foreign equity on American exchanges without dealing with another country’s markets. Investors care because ADSs make foreign stocks easier to access, improve liquidity and settlement in dollars, and can affect dividend payments, voting rights and regulatory oversight compared with buying the underlying foreign shares directly.

vesting financial

"The RSUs are expected to vest in eight installments of 30%, 15%, 15%, 10%,"

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.

tax withholding obligations financial

"Represents ADSs withheld to satisfy applicable tax withholding obligations in connection"

expiration dates financial

"The restricted share units do not have expiration dates."
