Convertible Promissory Note financial
"Reflects a convertible note that is convertible into shares of common stock of the Issuer."
A convertible promissory note is a loan a company takes now that can later be turned into shares instead of being repaid in cash. Think of it as lending money with the option to accept ownership in the business down the road; that matters to investors because it affects who gets paid first, how much ownership existing shareholders keep, and the company’s future valuation and cash needs. Terms such as conversion price, interest and maturity determine the financial impact.
Series C Preferred Stock financial
"The Series A-3 Preferred Stock, Series A-4 Preferred Stock and Series C Preferred Stock are convertible into shares of Class B 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.
Class B Common Stock financial
"convertible into shares of Class B Common Stock on a 1-for-2.418 basis, at the holder's election"
A class B common stock is one of multiple types of a company’s ordinary shares that carries specific rights—often different voting power or dividend priority—compared with other classes. For investors it matters because those differences affect how much influence you have over company decisions, the income you might receive, and how freely the shares trade; think of it like owning a car with different keys: some keys let you start the engine and open the trunk, others only unlock the door.
initial public offering financial
"will automatically convert into shares of the Issuer's common stock upon the closing of the initial public offering pursuant to their 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.
beneficial ownership financial
"disclaim beneficial ownership over the securities held by IIF II, except to the extent of their respective pecuniary interests therein"
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
pecuniary interests financial
"except to the extent of their respective pecuniary interests therein, if any."
