American Depositary Shares financial

"Ordinary Shares may have been represented by American Depositary 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 stock unit financial

"each time-based restricted stock unit and performance-based restricted stock unit"

A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.

performance-based restricted stock unit financial

"time-based restricted stock unit and performance-based restricted stock unit"

A performance-based restricted stock unit is a promise of company shares given to an employee that only becomes actual stock if specific performance targets are met and any required time at the company is completed. For investors, these awards matter because they can dilute existing shares when earned and signal management’s confidence or the company’s expected future performance, much like a bonus cheque that only clears when pre-set goals are reached.
