Schedule 13D regulatory

"filing person has previously filed a statement on Schedule 13G"

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.

beneficially owned financial

"Aggregate amount beneficially owned by each reporting person 4,423,894.00"

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.

restricted stock units financial

"the Issuer awarded the Reporting Person 1,046,899 restricted stock units"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

voting and dispositive authority regulatory

"sole voting and dispositive authority over 4,370,278 common shares"

warrants exercisable financial

"Includes 105,264 shares underlying warrants exercisable for Issuer common shares"
