beneficially owned financial

"Amount beneficially owned: 223,050"

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.

4.99% Blocker regulatory

"subject to the 4.99% Blocker (defined below)"

sole dispositive power financial

"Sole Dispositive Power 223,050.00"

Sole dispositive power is the exclusive legal authority to decide what happens to a security — for example, whether to sell, transfer, or retain shares — without needing anyone else’s permission. Investors care because it signals who truly controls the economic outcome of an investment: like holding the only key to a safe, the holder can realize gains or losses and may trigger regulatory reporting, insider rules, or influence over corporate ownership.

sole voting power financial

"Sole Voting Power 223,050.00"

Sole voting power is the exclusive right to cast votes attached to a shareholder’s stock without needing approval from anyone else. Like holding the only remote control for a TV, it lets that holder decide corporate matters such as board members, mergers, and policy changes, making it important to investors because it concentrates control and can strongly influence a company’s strategy and the value of its shares.

common warrants financial

"shares of common stock issuable upon the exercise of common warrants"

A common warrant is a tradable instrument that gives its holder the right to buy a company’s common shares at a fixed price within a set time period, similar to a coupon that can be redeemed later to purchase stock. Investors care because exercising warrants can boost potential gains if the stock rises, but it can also dilute existing shareholders by increasing the number of shares outstanding, which can lower per-share value.
