Private Placement Units Purchase Agreement financial

"acquired pursuant to a Private Placement Units Purchase Agreement by and between the Sponsor and the Issuer"

Class B ordinary shares financial

"Does not include 7,666,667 Class B ordinary shares, which shares will automatically convert"

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.

Founder Shares financial

"subject to adjustment as described under the heading "Description of Securities--Founder Shares""

Founder shares are the ownership stakes given to the people who start a company, often with extra voting power or protections compared with ordinary shares. For investors, they matter because founders’ control and incentives influence decisions about strategy, hiring, and whether the company sells or stays independent — like a family that keeps majority voting rights in a household decision. High founder ownership can mean stable leadership but also a risk that outside shareholders have less influence.

beneficial ownership financial

"Each of Cohen and Cohen LLC disclaims any beneficial ownership of the securities held by the Sponsor"

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.
