Deferred Stock Units financial

"Annual Deferred Stock Units ("DSUs") award which vests in 12 equal monthly"

Deferred stock units are promises from a company to give an employee shares of stock at a future date, often after certain conditions are met or after leaving the company. They function like a form of delayed compensation, allowing employees to earn shares over time. For investors, they represent potential future ownership in the company, but do not provide immediate voting rights or dividends until the shares are actually received.

change of control financial

"immediately prior to a change of control, in each case, provided that"

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.

continuous service financial

"provided that the Reporting Person ("RP") remains in continuous service"
