beneficially owned financial

"Amount beneficially owned: 2,272,164.43"

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.

convertible bonds financial

"shares that can be acquired from convertible bonds held by Jane Street"

A convertible bond is a loan a company issues that pays regular interest and can be exchanged for a fixed number of the company’s shares under specified terms. It matters to investors because it combines the steady income and lower downside risk of a bond with the upside potential of owning stock—like holding a ticket that can be cashed for equity if the share price rises—affecting returns, risk, and shareholder dilution.

shared voting power financial

"Shared Voting Power 2,272,164.43"

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.

shared dispositive power financial
