  1. On June 7, 2023, the reporting person was granted 75,000 RSUs, vesting in three equal annual installments beginning on the first anniversary of the grant date. Each RSU represents a conditional right to receive a cash payment equal to the fair market value of one Common Share of the Issuer or, at the Issuer's discretion, a number of Common Shares (or a combination of cash and Common Shares) equal to the fair market value of one Common Share. One-third of the RSUs vested on June 8, 2026 and were converted into Common Stock on a one-to-one basis at the Issuer's discretion. The price used to calculate the June 7 RSU vesting was C$0.72, which was the closing price Issuer's Common Shares as reported on the Toronto Stock Exchange on June 8, 2026. The price was converted using the Bank of Canada exchange rate for June 8, 2026 of C$1.3947= US$1.00.

Restricted Share Units financial
"the reporting person was granted 75,000 RSUs, vesting in three equal annual installments"
Restricted share units (RSUs) are a promise from a company to give an employee or service provider actual shares or cash equal to the shares after certain conditions are met, typically staying with the company for a set time or hitting performance targets. Think of them like a time-locked gift card that becomes usable only after you’ve earned it. For investors, RSUs matter because they align employee incentives with company performance and can increase the number of shares outstanding over time, diluting existing ownership and affecting earnings per share.
tax-withholding disposition financial
"transaction_action": "tax-withholding disposition""
A tax-withholding disposition is an event or transaction—such as selling or transferring securities, exercising options, or receiving compensation—that triggers a requirement to hold back part of the payment and remit it to tax authorities. It matters to investors because it reduces the cash they receive immediately and can change the timing and amount of taxable income, like a cashier taking a portion of your sale proceeds to pay taxes before you get the rest.
derivative exercise/conversion financial
"transaction_action": "derivative exercise/conversion""
fair market value financial
"Each RSU represents a conditional right to receive a cash payment equal to the fair market value of one Common Share"
The price a willing buyer and a willing seller would agree on for an asset or security when neither is under pressure and both have access to the same information. Think of it as the market’s neutral estimate of what something is worth, like the price two neighbors would settle on for a car after comparing similar listings. Investors care because fair market value guides buying and selling decisions, tax reporting, portfolio valuation, and how accurately company assets are reflected in financial statements.
exercise or conversion of derivative security financial
