6 terms

Schedule 13D regulatory

"This Amendment No 4 to the filed, relating to the common stock"

A Schedule 13D is a legal document that investors file with regulators when they buy a large enough stake in a company to potentially influence its management or decisions. It provides details about the investor’s intention, ownership stake, and plans, helping other investors understand who is gaining control and what their motives might be.

Securities Purchase Agreement regulatory

"the Issuer entered into a Securities Purchase Agreement underwriting agreement"

A securities purchase agreement is a written contract between a buyer and a seller outlining the terms for buying or selling financial assets such as stocks or bonds. It specifies details like the price, quantity, and conditions of the transaction, similar to a shopping list with agreed-upon terms. For investors, it provides clarity and legal protection when transferring ownership of these financial instruments.

pre-funded warrant financial

"each Unit comprised of one share of the Issuer's Common Stock, and one pre-funded warrant to purchase one share"

A pre-funded warrant is a financial instrument that gives the holder the right to buy shares of a company's stock at a set price, with most of the purchase cost already paid upfront. It functions like a nearly fully paid option, allowing investors to secure shares quickly while minimizing the amount of additional money they need to invest later. This helps investors gain ownership rights efficiently, often used to avoid certain regulatory restrictions or to prepare for future stock purchases.

Employee Stock Options financial

"Employee Stock Options to purchase common stock at an exercise price ranging from $0.585 to $17.34"

Employee stock options are contracts that give workers the right to buy a company's shares at a set price sometime in the future, like a coupon that lets you purchase stock at today’s price later on. Investors care because they align employees’ incentives with company performance and create a potential future claim on shares that can reduce existing owners’ percentage and add to a company’s reported compensation costs.

open market transactions financial

"purchases of Common Stock in open market transactions using their personal funds"

Open market transactions are the buying and selling of a company’s shares or other securities conducted on public exchanges or through the wider market rather than through private deals or negotiated placements. They matter to investors because these trades change supply and demand in real time—like shoppers affecting a store’s inventory—and so can move prices, signal management or investor sentiment, affect liquidity, and alter ownership stakes that influence future returns and risk.

beneficially owned financial

"Aggregate amount beneficially owned by each reporting person 1,965,916.00"

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.
