Restricted stock units financial

"Shares issued for vesting of 7/20/2023 RSU grant"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

Performance Stock Units (PSUs) financial

"Performance Stock Units (PSUs) convert into common stock on a one-for-one basis"

Performance stock units (PSUs) are a form of executive or employee pay that promise company shares only if pre-set performance goals are met over a defined period; think of them as a bonus paid in stock that arrives only when the company hits agreed targets. Investors watch PSUs because they affect the number of shares outstanding (dilution) and reveal how management’s pay is tied to financial or operational results, aligning incentives with shareholder outcomes.
