beneficial ownershipfinancial
"Calculation of percentage of beneficial ownership represents beneficial ownership of Class A Ordinary Shares"
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
Class B ordinary sharesfinancial
"Class B ordinary shares that are convertible into the Issuer's Class A ordinary shares on a one-for-one basis"
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. For investors, they represent a way to hold part of the company’s value and influence its decisions, often with fewer voting rights than Class A shares. Understanding these shares helps investors assess their level of control and potential returns within a company.
anti-dilution rightsfinancial
"convertible into the Issuer's Class A ordinary shares on a one-for-one basis, subject to adjustment pursuant to certain anti-dilution rights"
private placement unitsfinancial
"200,000 Class A ordinary shares included in private placement units acquired by Security Holdings"
shared voting powerfinancial
"Shared Voting Power 7,533,334.00"
Shared voting power occurs when two or more parties jointly have the right to vote or decide how a block of company shares is cast, like co-owners who must agree before moving a piece of furniture. Investors care because who controls voting rights affects board elections, major corporate decisions and takeover outcomes, and shared control can alter regulatory disclosures and the practical influence any holder has over a company’s direction and value.
