beneficially owned financial
"Aggregate amount beneficially owned by each reporting person 19,004,925.00"
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.
Schedule 13D regulatory
"This Amendment No. 4 relates to the Statement on (this "") filed on April 1, 2026"
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.
Annual Information Form regulatory
"the Company's Annual Information Form for the year ended December 31, 2025"
A company's annual information form is a comprehensive regulatory filing that lays out its business description, key assets, risks, legal matters and other background details shareholders need to understand the company’s operations. Think of it as a detailed owner’s manual or dossier that supplements financial statements, helping investors do deeper homework on how the business works and what could affect its future performance.
Investor Rights Agreement financial
"Investor Rights Agreement between Western Copper and Gold Corporation and Rio Tinto Canada Inc."
A legally binding contract between a company and its investors that spells out investors’ core protections and privileges—such as voting rights, how and when shares can be sold, information access, and steps for resolving disputes. Think of it like a rulebook or homeowner association agreement for ownership: it clarifies who gets a say, how value can be realized, and what protections exist if things go wrong, making investment risks and expectations clearer for shareholders.
Subscription Agreement financial
"Subscription Agreement between Western Copper and Gold Corporation and Rio Tinto Canada Inc."
A subscription agreement is a legal contract in which an investor agrees to buy a specific number of a company’s shares or other securities under set terms, including price, payment method and conditions for closing the sale. It matters to investors because it legally locks in their purchase and the company’s obligations, determines ownership percentage and any investor rights, and can include conditions or promises that affect future control or returns—like signing a detailed purchase order for equity.
