Key Terms

3 terms

restricted stock units financial

"Represents an award of restricted stock units with respect to Class A Common Stock"

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.

directed share program financial

"purchased by the Reporting Person through the directed share program"

initial public offering financial

"directed share program conducted in connection with the Issuer's initial public offering"

An initial public offering (IPO) is when a private company first sells its shares to the public and becomes a stock-listed company. It matters because it allows the company to raise money from a wide range of investors, helping it grow, while giving early shareholders a way to sell some of their ownership.
