Class B Ordinary Shares financial

"the Class B ordinary shares, par value $0.0001 per share, of the issuer"

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.

automatic convert financial

"the Class B ordinary shares ... will automatically convert into Class A ordinary shares"

one-for-one basis financial

"convert into Class A ordinary shares ... on a one-for-one basis"

dispositive power financial

"share voting and dispositive power over the shares held by ArgoSat"

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.

pecuniary interest financial

"disclaims beneficial ownership of the shares except to the extent of his pecuniary interest"
