restricted stock units financial

"Includes 3,305 unvested time-based restricted stock units, each entitling the holder"

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.

401k financial

"indirect ownership of 784 shares of common stock held through a 401(k) plan"

An employer-sponsored retirement savings plan in the United States that lets workers set aside part of their paycheck into investments with tax advantages; some plans also include employer matching contributions, which is like free money added to your savings. It matters to investors because 401(k) balances represent a large pool of household retirement assets that influence personal financial security, investor behavior, and long-term demand for stocks and bonds.
