"Each share of Series C Redeemable Convertible Preferred Stock automatically converted"
initial public offering financial
"automatically converted into shares of the Issuer's common stock 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.
conversion ratio financial
"upon the closing of the Issuer's initial public offering at the applicable conversion ratio of 9.29-for-one"
The conversion ratio is the number of common shares an investor receives when a convertible security (like a bond or preferred share) or an exchangeable instrument is turned into ordinary stock. It matters because it tells investors how much ownership or dilution will occur — similar to knowing how many slices you get when you trade in a coupon — and directly affects the value you get from the convertible and the company’s future share count.
pecuniary interests financial
"disclaim beneficial ownership of such shares except to the extent of their respective pecuniary interests"
