Unknown transaction entries 11 entries Holding-type entries with unknown transaction codes in summary
Series E-1 Preferred Stock financial
"Each share of Series B Preferred Stock, Series D Preferred Stock, Series F Preferred Stock, Series E-1 Preferred Stock and Series E-2 Preferred Stock will convert"
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.
as-converted basis financial
"fully diluted shares of capital stock (on an as-converted basis) outstanding immediately prior to Offering, excluding the Convertible Notes."
As-converted basis means counting securities that can become common stock—like convertible bonds or preferred shares—as if they already were common shares when calculating totals such as shares outstanding, ownership percentages, or per-share metrics. Investors use it to see the potential dilution and the “what-if” size of the shareholder base; it’s like imagining all restaurant coupons have been redeemed so you know how crowded the table could become and how slices of the pie would shrink.
warrant to purchase Series B Preferred Stock financial
"Common stock is issuable upon exercise of warrant to purchase Series B Preferred Stock."
initial public offering financial
"will convert into Common Stock immediately prior to the completion of the Issuer's initial public offering (the "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.
