beneficial owner financial

"Nantahala may be deemed to be the beneficial owner of 1,178,203 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 1,178,203.00"

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.

shared dispositive power financial

"Shared Dispositive Power 1,178,203.00"

convertible securities financial

"Shares which may be acquired by the Reporting Persons within sixty days 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 in respect of shares"

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.

investment adviser financial

"Nantahala, an investment adviser as described in ss. 240.13d-1(b)(1)(ii)(E)"

An investment adviser is a person or firm that professionally manages money and gives recommendations about buying, selling, or holding investments. Like a financial coach or guide, they have a legal duty to act in a client's best financial interest, so their advice, fees and potential conflicts can directly affect returns and risk — making their role important for investors who want informed, accountable help with portfolios.
