Restricted Share Units financial

"the reporting person was granted 150,000 restricted share units ("RSUs") which will cliff vest"

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.

cliff vest financial

"150,000 restricted share units ("RSUs") which will cliff vest on July 1, 2026"

A cliff vest is a schedule for stock options or restricted shares where no ownership rights are earned until a fixed date, after which a set portion becomes fully owned all at once — like a probation period that suddenly unlocks pay. Investors watch cliff vests because they influence when insiders can sell shares, affect staff retention and dilution timing, and help predict short-term changes in a company’s shareholder makeup.

fair market value financial

"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.

Toronto Stock Exchange financial

"closing price Issuer's Common Shares as reported on the Toronto Stock Exchange on May 11, 2026"

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.
