Series A-1 Preferred Stock financial
"Represents shares of the Issuer's Series A-1 Preferred Stock and Series B Preferred Stock held directly..."
Series A-1 preferred stock is a specific class of company shares created in an early financing round that typically gives its holders priority over common shareholders for dividends and money if the company is sold or liquidates. Think of it as a special ticket with upfront privileges — often convertible into ordinary shares and sometimes carrying voting or protective rights — so investors use it to reduce risk and preserve control compared with ordinary stock.
Series B Preferred Stock financial
"Each share of the Issuer's Series B Preferred Stock is convertible, at the option of the holder..."
Series B preferred stock is a type of ownership share issued by a company that offers certain advantages over common stock, such as priority in receiving dividends or assets if the company is sold or liquidated. It is typically issued after an initial round of funding, making it a way for investors to support a company's growth while gaining some protections and benefits. This stock matters to investors because it often provides a more secure investment position with potential for future growth.
convertible financial
"Each share of the Issuer's Series A-1 Preferred Stock is convertible, at the option of the holder..."
A convertible is a type of investment that starts as a loan or preferred stake (like a bond or preferred share) but can be exchanged for common shares of the company at a set price or under certain conditions. It matters to investors because it offers a mix of steady income and downside protection like a loan, plus the upside of stock ownership if the company does well—similar to holding a coupon that you can trade for a full ticket if the event becomes valuable.
initial public offering financial
"will automatically convert upon 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.
beneficial ownership financial
"Dr. Koppel disclaims beneficial ownership of such securities, except to the extent of his pecuniary interest 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 interest financial
"Dr. Koppel disclaims beneficial ownership of such securities, except to the extent of his pecuniary interest therein."
