American depositary share financial

"Each American depositary share represents one Class A ordinary share."

An American Depositary Share (ADS) is a U.S.-listed certificate that represents a specified number of shares in a foreign company, held by a custodian bank; it works like a receipt that allows U.S. investors to buy and trade foreign equity on American exchanges without dealing with another country’s markets. Investors care because ADSs make foreign stocks easier to access, improve liquidity and settlement in dollars, and can affect dividend payments, voting rights and regulatory oversight compared with buying the underlying foreign shares directly.

restricted shares financial

"Represents restricted shares granted to the reporting person pursuant to the issuer's share incentive plans."

Restricted shares are company stock that cannot be sold or transferred immediately because they are subject to legal or contractual limits, such as a required holding period or performance conditions. They matter to investors because these locked-up shares can affect a company’s available stock for trading, future dilution, and insider incentives—imagine a gift that can’t be cashed until certain conditions are met, which changes when and how much supply can suddenly enter the market.

share incentive plans financial

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

Class A ordinary share financial

"Each restricted share represents the contingent right to receive one Class A ordinary share."

A Class A ordinary share is a type of common stock a company issues that carries a specific set of rights—most often particular voting power, dividend terms, or transfer rules—distinct from other share classes. For investors it matters because those rights affect control over company decisions, how income is paid out, and how easy shares are to buy or sell; think of it like a tiered ticket that gives different access and influence at the same event.
