Convertible Notes financial
"includes 36,165,308 Common Shares that Kopernik Global Investors, LLC has the right to acquire pursuant to the Convertible Notes"
Convertible notes are a type of short-term loan that a company receives from investors, which can later be turned into company shares instead of being paid back in cash. They matter to investors because they offer a way to support a company early on while giving the potential to own a stake in its success if the company grows and later raises more funding.
beneficially own financial
"The Reporting Persons may be deemed to beneficially own, in the aggregate, 83,628,221 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 dispositive power financial
"shared power to dispose of, or direct the disposition of, 83,628,221 Common Shares"
conversion price financial
"convertible at any time at the option of Kopernik Global Investors into Common Shares at a per share conversion price of $0.3557"
The conversion price is the fixed price at which a convertible security, like a bond or preferred stock, can be exchanged for shares of common stock. It acts like a set rate that determines how many shares an investor can receive if they choose to convert their investment. This helps investors understand the value and potential benefits of converting their securities into company shares.
change of control financial
"subject to adjustment in certain circumstances (i.e., including a change of control)"
A change of control occurs when the ownership or management of a company shifts significantly, such as through a sale, merger, or acquisition, resulting in new leadership or ownership structure. This change can impact the company's direction and decision-making, which is important for investors because it may affect the company's stability, strategy, and future prospects.
equity financing financial
"If the Issuer proceeds with an equity financing in the future, the terms of the Convertible Notes require that the Issuer redeem the Convertible Notes at 150% of the principal amount"
Equity financing is when a company raises money by selling ownership pieces (shares) to investors instead of borrowing; think of selling slices of a pie to get cash for the business. It matters to investors because buying shares gives them a claim on future profits and a voice in decisions, while existing owners give up some control and the value of each slice can change as the company grows or falters.
