"Adoption date of referenced Rule 10b5-1(c) plan is: 05/05/2026"

Restricted Stock Units (RSUs) financial

"Number of shares includes 3,578 Restricted Stock Units (RSUs)"

Restricted stock units (RSUs) are a type of company promise to give employees shares of stock in the future, usually after certain conditions like working for a set time. They are like a gift promised today that you receive later, which can become valuable if the company's stock price goes up. RSUs matter because they are a way companies reward employees and can be a significant part of compensation.

Deferred Stock Units (DSUs) financial

"and 11,992 Deferred Stock Units (DSUs)"

Deferred stock units (DSUs) are a form of long-term pay that promises an employee or director future company shares or cash equal to the share value at a later date, usually after leaving the company or at a set vesting time. Think of them as a delayed paycheck tied to the stock: they align recipients’ interests with long-term share performance and matter to investors because they create potential future dilution and signal how management is rewarded and incentivized.
