Employee Share Option financial

"2025 Employee Share Option (right to buy)"

American Depositary Shares financial

"Number of underlying securities and exercise price expressed in terms of American Depositary Shares ("ADS")."

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.

exercise price financial

"Number of underlying securities and exercise price expressed in terms of American Depositary Shares ("ADS")."

The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.

vests and becomes exercisable financial

"The option vests and becomes exercisable in four equal annual installments"

Ordinary Shares financial

"The Ordinary Shares may be represented by ADSs."

Ordinary shares are a type of ownership stake in a company, giving shareholders a right to participate in the company’s profits and decision-making through voting. They are similar to owning a piece of a business, and their value can rise or fall based on the company's performance. Investors buy ordinary shares to potentially earn dividends and benefit from the company's growth over time.
