beneficial owner financial

"may be deemed the beneficial owner of the 6,772,260 Shares directly beneficially owned"

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.

shared voting power financial

"6 | Shared Voting Power 6,772,260.00 7 | Sole Dispositive Power 0.00"

Shared voting power occurs when two or more parties jointly have the right to vote or decide how a block of company shares is cast, like co-owners who must agree before moving a piece of furniture. Investors care because who controls voting rights affects board elections, major corporate decisions and takeover outcomes, and shared control can alter regulatory disclosures and the practical influence any holder has over a company’s direction and value.

dispositive power financial

"7 | Sole Dispositive Power 0.00 8 | Shared Dispositive Power 6,772,260.00"

Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.

Section 13(d) of the Securities Exchange Act of 1934 regulatory

"for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended"

Section 13(d) of the Securities Exchange Act of 1934 is a U.S. rule that requires anyone who buys more than 5% of a public company’s shares to publicly disclose who they are, how many shares they own, and their intentions toward the company. For investors, this is like a neighborhood alert when someone acquires a large stake in a building: it reveals potential changes in control or strategy that could affect the stock’s price, governance, or future direction.

percent of class financial

"(b) | Percent of class: The following percentages are based on 73,894,020 Shares"

Percent of class is the portion of a specific category of securities—such as a company’s common shares, preferred shares, or a bond series—that takes part in or approves a corporate action (vote, consent, tender, etc.). Investors watch this number because it reveals how much support or opposition exists within that particular shareholder group; like counting how many members of a club back a proposal, it can determine whether a plan passes or how influence is distributed.
