Class B Ordinary Shares financial

"Represents Class B Ordinary Shares (founder shares) held indirectly through membership interests"

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

"Represents Class B Ordinary Shares (founder shares) held indirectly through membership interests"

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.

membership interests financial

"held indirectly through membership interests in Oceanhawk Acquisition I Sponsor, LLC"

An ownership stake in a limited liability company (LLC) that represents a holder’s share of the business’s profits, losses, and decision-making power. Think of it like a slice of the company’s pie and a seat at its management table: it determines how much money the owner can receive and how much influence they have over company choices. Investors care because these interests affect returns, control, transferability, and tax treatment.
