American Depository Shares financial

"Class A Ordinary Shares underlying American Depository Shares (each representing 15 Class A Ordinary Shares)"

American depository shares are U.S.-listed securities that stand in for a foreign company’s ordinary shares, held by a U.S. bank which issues the ADS so investors can trade the foreign stock in U.S. dollars and on U.S. exchanges. Think of them like a locally wrapped version of a foreign product—easier to buy and sell at home—but they still carry risks from currency differences, foreign rules and potential limits on voting rights, so they affect access, liquidity and investment risk.

beneficially owned financial

"Amount beneficially owned: 38,900,282 American Depository Shares, representing 583,504,230 Class A ordinary shares"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

shared voting power financial

"Shared power to vote or to direct the vote: 583,504,230"

Shared voting power occurs when two or more parties jointly have the right to vote or decide how a block of company shares is cast, like co-owners who must agree before moving a piece of furniture. Investors care because who controls voting rights affects board elections, major corporate decisions and takeover outcomes, and shared control can alter regulatory disclosures and the practical influence any holder has over a company’s direction and value.

shared dispositive power financial

"Shared power to dispose or to direct the disposition of: 583,504,230"

pecuniary interest financial

"disclaims beneficial ownership of the shares reported herein except to the extent of their respective pecuniary interest"
