Institutional Investor Relations Expert

Related private-fund entities control about 9.5% of Class A shares; positions are not for trading per the filing.

The excerpt explicitly states the shares are "not for trading" and assigns shared voting/dispositive power to the listed entities. The filing references the issuer's Form 20-F for the outstanding share base used to calculate percentages.

Stakeholders may note the holding structure (direct ownership by Inception Five and Rosewood Eight, upstream fund/GP relationships) when assessing potential future activity; the filing does not state any planned transactions.

4 terms

Shared Voting Power regulatory

"Shared Voting Power 36,484,430.00 listed for multiple entities"

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.

Beneficially owned regulatory

"Amount beneficially owned: 40,968,718."

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.

Class A Ordinary Shares market

"Title of class of securities: Class A Ordinary Shares, par value of $0.001 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.

Dispositive Power regulatory

"Shared Dispositive Power 36,484,430.00 reported for several entities"

Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.
