5 terms

beneficially owned financial

"Represents 333,832,129 ordinary shares ... beneficially owned by Ching-Dong Wang"

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.

voting and dispositive power financial

"Mr. Wang is deemed to have voting and dispositive power over the securities"

Ordinary Shares financial

"Represents 333,832,129 ordinary shares, par value of $0.00001 per share (the "Ordinary Shares")"

Ordinary shares are a type of ownership stake in a company, giving shareholders a right to participate in the company’s profits and decision-making through voting. They are similar to owning a piece of a business, and their value can rise or fall based on the company's performance. Investors buy ordinary shares to potentially earn dividends and benefit from the company's growth over time.

par value financial

"ordinary shares, par value of $0.00001 per share"

Par value is the fixed amount printed on a bond or stock that represents its original value when issued. It’s like the face value of a coin or bill—what the issuer promises to pay back or the starting price of a stock—though it often doesn’t change with market prices. It matters because it helps determine certain financial details, like how much the company will pay back at maturity.

ten percent owner financial

"Mr. Wang is identified as a ten percent owner in the metadata"
