4 terms

Schedule 13G regulatory

"Item 1. | (a) | Name of issuer: Iris Acquisition Corp"

A Schedule 13G is a formal document that investors file with the government when they acquire a large ownership stake in a company, usually for investment purposes rather than control. It helps keep the public informed about who owns significant parts of a company's shares, which can influence how the company is managed and how investors make decisions. Filing this schedule is important for transparency and understanding the ownership landscape of publicly traded companies.

Units financial

"Title of class of securities: Units, each consisting of one Class A ordinary share"

Units are bundled securities sold as one package in a financing—commonly a share paired with an instrument that gives the holder the right to buy more shares later. For investors this matters because a unit’s extra component can change future supply of shares and potential returns, similar to buying a combo with a coupon that can be redeemed later and alter what you actually receive and what others might own.

Beneficially owned regulatory

"Amount beneficially owned: 1,152,750 The Reporting Person may be deemed"

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.

Dispositive power regulatory

"Sole power to dispose or to direct the disposition of: 1,152,750"

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.
