Restricted Share Units financial

"the reporting person was granted 1,500,000 RSUs vesting on August 14, 2026"

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.

Common Shares financial

"equal to the fair market value of one Common Share of the Issuer"

Common shares are the basic units of ownership in a company that give holders a claim on profits and a right to vote on key matters, like electing the board. Think of them as membership cards in a club: they let you share in successes and losses, but in a bankruptcy or liquidation they are paid after creditors and preferred shareholders, so their value can swing more and matters for assessing risk and potential return.

exercise price or tax liability financial

"Payment of exercise price or tax liability by delivering or withholding securities"

Toronto Stock Exchange market

"closing price Issuer's Common Shares as reported on the Toronto Stock Exchange"

The Toronto Stock Exchange is Canada’s largest organized marketplace where shares of publicly traded companies are bought and sold, similar to a large, regulated marketplace for company ownership. It matters to investors because it provides transparent prices, rules that help protect buyers and sellers, and access to many Canadian and international businesses, so movements there can signal economic trends and affect portfolio values.
