beneficially own financial

"The Reporting Persons beneficially own an aggregate of 11,266,571 Common Shares, representing 12.1% of the outstanding Common Shares."

Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.

shared voting power financial

"Each of Tether Global Investments Fund, S.I.C.A.F., S.A. and Mr. Devasini has shared voting and dispositive power with respect to the beneficially owned 11,266,571 Common Shares."

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.

shared dispositive power financial

"Tether International, S.A. de C.V. has shared voting and dispositive power with respect to 9,266,571 Common Shares."

Schedule 13D regulatory

"This statement on amends the of Tether Holdings, S.A. de C.V. ... and constitutes Amendment No. 7 to the ."

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.

Management Information Circular regulatory

"This percentage is calculated based upon 93,442,762 shares outstanding as of May 7, 2026, as reported in the Management Information Circular filed as an exhibit to the Form 6-K."

A management information circular is a document sent to shareholders ahead of a company meeting that explains who is asking for votes, what decisions will be made, and why management recommends a particular outcome. Like an instruction booklet and argument sheet combined, it lays out details such as board nominees, executive pay, major transactions and any conflicts, helping investors decide how to vote and judge whether leadership choices could affect the company’s future value.
