"Represents an equal number of restricted stock units ("RSUs"). Each RSU represents the right to receive a share..."
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.

A compensation committee is a group within a company's leadership responsible for setting and reviewing how much top executives and employees are paid, including salaries, bonuses, and benefits. It matters to investors because fair and effective pay decisions can influence a company's performance, leadership motivation, and overall governance, helping ensure that the company’s management is aligned with shareholders’ interests.
