4 terms

Directed Share Program financial

"Shares acquired pursuant to a Directed Share Program in connection with the initial public offering"

restricted stock unit ("RSU") financial

"Each restricted stock unit ("RSU") represents the right to receive one share of Class A common stock"

initial public offering financial

"Directed Share Program in connection with the initial public offering of X-Energy, Inc."

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.

restricted stock financial

"Includes 17,540 shares of restricted stock."

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.
