5 terms

Directed Share Program financial

"Shares acquired pursuant to a Directed Share Program in connection with the initial public offering of X-Energy, Inc."

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

"Shares acquired pursuant to a 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 29,410 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.

open-market purchase financial

"transaction_action": "open-market purchase""

An open-market purchase is when an investor or a company buys shares on a public stock exchange at the going market price, rather than through a private deal. It matters to investors because these purchases change how many shares are available, can push the stock price up or signal confidence from large buyers, and often affect per-share metrics like earnings—think of it like someone buying lots of apples off a grocery shelf, reducing supply and potentially raising the price.
