beneficial owner financial

"Nantahala may be deemed to be the beneficial owner of 3,995,579 Shares"

A beneficial owner is the person who ultimately owns or controls a financial asset or property, even if their name isn't directly on official documents. Think of it like someone who secretly holds the keys to a safe deposit box—others may appear to have access, but the true owner is the one who benefits from what's inside. Identifying beneficial owners helps ensure transparency and prevent illegal activities like money laundering or fraud.

shared voting power financial

"Shared Voting Power 3,995,579.00"

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.

dispositive power financial

"Shared Dispositive Power 3,995,579.00"

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.

convertible securities financial

"612,244 Shares which may be acquired ... through the exercise of convertible securities"

Convertible securities are bonds or preferred shares that can be exchanged for a company’s common stock at a predetermined price or under specified conditions. They matter because they combine the steadiness of a loan or fixed dividend with the potential upside of ownership; like a safety‑net that carries a one‑time ticket to become a shareholder, they affect expected returns and can dilute existing stock if converted.

control person financial

"each of Messrs. Harkey and Mack is filing this as a control person"

A control person is an individual or entity that can significantly influence a company’s decisions and direction through ownership, voting power, or contractual rights—think of them as the captain who can steer the ship. Investors care because a control person’s choices affect corporate strategy, board appointments, and transactions that can raise or lower a stock’s value, and they often carry additional legal responsibilities and disclosure requirements to protect other shareholders.
