Key Terms

restricted stock units financial

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.

rsus financial

RSUs, or restricted stock units, are a form of company shares given to employees as part of their compensation. They are typically awarded with certain restrictions, such as a waiting period before they can be fully owned or sold, similar to earning a gift that becomes fully yours over time. For investors, RSUs can impact a company's stock offerings and reflect how much the company relies on stock-based incentives to attract and retain talent.

nasdaq listing rule 5635(c)(4) regulatory

NASDAQ Listing Rule 5635(c)(4) is a rule that requires a company to get approval from its shareholders before selling a large amount of its shares, usually over 20%. This helps protect investors by making sure the company doesn't flood the market with new shares without their say, which could lower the stock's value.
