American Depositary Shares financial

"Each American Depositary Share represents 13 Ordinary Shares"

American depositary shares (ADSs) are a way for investors in the United States to buy shares of foreign companies without dealing with international markets directly. They represent ownership in a foreign company's stock and are traded on U.S. stock exchanges, making it easier for American investors to buy, sell, and own parts of companies from around the world.

restricted share unit award financial

"in connection with the vesting of a restricted share unit award previously granted"

mandatory tax withholding financial

"The sale was effected pursuant to a mandatory tax withholding provision"

vesting financial

"1/4th of the securities will vest on each anniversary of August 31, 2023"

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.
