Class A ordinary shares financial

"reported purchasing Class A ordinary shares in a direct transaction"

Class A ordinary shares are a type of ownership stake in a company that typically grants voting rights to shareholders, allowing them to have a say in important company decisions. They often come with priority in receiving dividends or profits, making them attractive to investors seeking influence and potential income. These shares help distinguish different levels of ownership and rights within a company's stock structure.

Class B ordinary shares financial

Class B ordinary shares are a type of ownership stake in a company that typically come with different voting rights or privileges compared to other share classes.
