Class A Ordinary Shares financial

"The transaction involved 10,000 Class A Ordinary Shares at $10.00 per share."

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.

initial public offering financial

"Reflects purchase of the Issuer's securities in the Issuer's initial public offering."

An initial public offering (IPO) is when a private company first sells its shares to the public and becomes a stock-listed company. It matters because it allows the company to raise money from a wide range of investors, helping it grow, while giving early shareholders a way to sell some of their ownership.

purchase in open market or private transaction financial

"Transaction code "P" is described as a purchase in open market or private transaction."
