Series C Preferred Stock financial
"Each share of Series C Preferred Stock will convert into Common Stock"
A Series C preferred stock is a specific class of ownership issued during a later funding round that gives holders priority over common shareholders for getting paid and receiving dividends, like having a reserved lane in traffic when money is distributed. It often includes agreed rights such as a fixed payout, protection against dilution, and the option to convert into common shares, so investors treat it as a mix of safety and upside potential.
initial public offering financial
"convert into Common Stock immediately prior to the completion 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.
beneficially own financial
"may be deemed to beneficially own such securities"
Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.
dispositive power financial
"share voting and dispositive power with respect to the shares held"
Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.
