Preferred Stock financial
"collectively, the "Preferred Stock" of the Issuer are convertible into shares of Common Stock"
Preferred stock is a type of ownership in a company that typically offers investors higher and more consistent dividend payments than common stock. Unlike regular shares, preferred stock usually doesn’t come with voting rights but provides a priority claim on the company’s assets and profits, making it a more stable and predictable investment option. This makes preferred stock attractive to those seeking steady income with lower risk.
initial public offering financial
"All shares of the Preferred Stock automatically converted into shares of Common Stock immediately prior to the closing of 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.
