Restricted Stock Unit (RSU) financial

"security_title: "Restricted Stock Unit (RSU)" with 20,000.0000 units exercised"

A restricted stock unit (RSU) is a promise from a company to give an employee company shares (or cash equal to their value) at a future date if certain conditions are met, such as staying with the company or hitting performance targets. For investors, RSUs matter because when they convert into actual shares they increase the number of shares available and can create selling pressure as employees cash out—think of them as a future paycheck paid in company stock.
