beneficial owner financial

"is deemed to be the beneficial owner of 6,750,079 shares, or 18.48%"

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.

Series D Non-Voting Convertible Preferred Stock financial

"shares of Common Stock issuable upon conversion of Series D Non-Voting Convertible Preferred Stock"

Series E Non-Voting Convertible Preferred Stock financial

"and Series E Non-Voting Convertible Preferred Stock (the "Preferred Stock")"

Investment Advisers Act of 1940 regulatory

"an investment adviser registered under Section 203 of the Investment Advisers Act of 1940"

A U.S. federal law that sets rules for people and firms who give investment advice, requiring them to register with regulators, be honest about conflicts, keep records, and follow basic standards of care. It matters to investors because those rules act like licensing and consumer protections — similar to having safety standards for a mechanic — helping ensure advisers act in clients’ financial interests and reducing the risk of fraud or misuse of funds.
