"American Depositary Shares ("ADSs") of the Issuer, each ADS representing one Class A Ordinary Share"
A U.S.-listed certificate that stands for a specific number of shares in a non‑U.S. company held by a U.S. bank, making the foreign stock tradable on American exchanges in dollars. Think of it like a local voucher that represents ownership of an overseas product — it lets U.S. investors buy and sell foreign companies without handling foreign currency or foreign brokerage accounts, but it can affect dividends, voting rights, fees, liquidity and exposure to currency and regulatory differences.
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.
