beneficially owned financial

"The aggregate purchase price of the 719,404 Shares beneficially owned by the Reporting Person"

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.

Conversion Shares financial

"which consists of Conversion Shares received by the Reporting Person upon the conversion of the Series AA Preferred Stock"

Series AA Preferred Stock financial

"upon the conversion of the Series AA Preferred Stock purchased by the Reporting Person pursuant to the SPA"

Form S-3/A regulatory

"based upon 18,589,787 Shares outstanding as of June 9, 2026, as reported in the Form S-3/A filed by the Issuer"

An amended Form S-3 (filed as Form S-3/A) is a revised U.S. Securities and Exchange Commission registration document that updates or corrects a company’s existing simplified plan to sell new securities to the public. Investors watch it because it often signals a company’s intention to raise money or provides material updates to information that affects value; think of it as an updated listing for additional shares that can change ownership stakes, borrowing plans, or future liquidity.

Schedule 13D regulatory

"If the filing person has previously filed a statement on Schedule 13G to report the acquisition"

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.
