Series E-1 Preferred Stock financial
"Each share of Series D Preferred Stock, Series F Preferred Stock, Series E-1 Preferred Stock and Series E-2 Preferred Stock will convert into Common Stock"
Convertible Notes financial
"The Convertible Notes will automatically convert into Common Stock immediately prior to the closing of the Offering."
Convertible notes are a type of short-term loan that a company receives from investors, which can later be turned into company shares instead of being paid back in cash. They matter to investors because they offer a way to support a company early on while giving the potential to own a stake in its success if the company grows and later raises more funding.
initial public offering financial
"will convert into Common Stock immediately prior to the completion of the Issuer's initial public offering (the "Offering") pursuant to its terms."
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.
fully diluted shares financial
"divided by the number of fully diluted shares of capital stock (on an as-converted basis) outstanding immediately prior to Offering"
Fully diluted shares are the total number of company shares that would exist if every claim that can be turned into common stock—such as employee stock options, warrants, and convertible debt or preferred shares—were exercised or converted. Investors use this number to see the biggest possible share count when calculating ownership percentages, earnings per share and dilution risk; think of it as counting all possible slices of a pie if every coupon could be redeemed.
beneficially own financial
"and as a result 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.
