Restricted Share Units financial

"On May 19, 2026, the reporting person was granted 58 RSUs, 1/3 of which vest annually over 3 years"

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.

"Each restricted share unit ("RSU") represents a contingent right to receive one common share or an equivalent value in cash"

vest financial

"58 RSUs, 1/3 of which vest annually over 3 years on the anniversary of the grant date"

A vest is the process by which an employee earns the right to receive certain benefits or ownership interests, such as stock or retirement funds, over time. It’s similar to earning a reward gradually, ensuring that the benefit becomes fully yours only after a set period or meeting specific conditions. This makes it important for investors because it determines when they can actually claim or use those benefits.
