restricted stock units (RSUs) financial

"grant of restricted stock units (RSUs) under the WD-40 Company 2016 Stock Incentive Plan"

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.

performance share units financial

"shares of restricted Common Stock received upon settlement of performance share units"

Performance share units are a type of company stock award given to employees that depend on the company meeting specific goals or targets. If these goals are achieved, the employee receives shares or the value of shares; if not, they may receive little or no compensation. This aligns employees’ interests with the company's success and encourages performance that benefits investors.

RSU award agreement financial

"Except as otherwise provided in the RSU award agreement"

A RSU award agreement is a legal contract that grants restricted stock units — promises of company stock to an employee or advisor — and spells out how many units are granted, when they become actual shares (vesting), and any conditions or tax rules. Investors care because these agreements create future share issuance and compensation cost, which can dilute existing holders and signal how the company rewards and retains key people, much like a delayed paycheck paid in stock.
