Conversion ratio 1-to-1 Each Series A, Series A-2 and Series B Preferred share converts into one share of Common Stock
Series A Preferred Stock financial
"Each share of Series A Preferred Stock, Series A-2 Preferred Stock and Series B"
Series A preferred stock is a type of ownership share in a company that gives investors certain advantages, such as priority in receiving profits or getting their money back if the company is sold or goes bankrupt. It is often issued during early funding stages to attract investors by offering more security than common shares. This stock matters to investors because it provides a safer way to invest while still holding potential for future gains.
Series B Preferred Stock financial
"Series A Preferred Stock, Series A-2 Preferred Stock and Series B Preferred Stock"
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.
initial public offering financial
"will convert automatically upon 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
"disclaims beneficial ownership of such securities except to the extent"
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
"except to the extent of its or his respective pecuniary interest therein"
