beneficially owned regulatory

"The 1,182,276 shares of common stock of the Issuer beneficially owned"

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.

Series B warrants financial

"exercised 216,138 Series B warrants"

Series B warrants are contracts issued alongside a company's Series B financing that give the holder the right to buy a set number of shares at a fixed price within a specified time. For investors, they matter because they can provide leveraged upside if the company grows, or they can dilute existing shareholders when exercised—like a coupon promising a future share at a known price that can add value or change ownership stakes.

beneficial ownership limitations regulatory

"not currently exercisable due to certain beneficial ownership limitations"

Beneficial ownership limitations are rules or contractual caps that restrict how much of a company’s stock an individual or entity can be treated as owning or controlling for legal, regulatory or corporate-governance purposes. They matter to investors because such limits affect voting power, reporting obligations, takeover risk and the ability to increase a stake — like an elevator weight limit or a lane divider that prevents any one car from taking over the whole road.

Schedule 13G regulatory

"Item 1. Name of issuer: DOMINARI HOLDINGS INC."

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.
