American depositary shares financial

"The Class A ordinary shares are held in the form of 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.

pecuniary interest financial

"disclaims beneficial ownership of the reported securities, except to the extent of any pecuniary interest therein."

beneficial owner financial

"may be deemed to be an indirect beneficial owner of, the securities held"

A beneficial owner is the person who ultimately owns or controls a financial asset or property, even if their name isn't directly on official documents. Think of it like someone who secretly holds the keys to a safe deposit box—others may appear to have access, but the true owner is the one who benefits from what's inside. Identifying beneficial owners helps ensure transparency and prevent illegal activities like money laundering or fraud.

share incentive plans financial

"RSUs granted to the reporting person pursuant to the issuer's share incentive plans."
