Series A Preferred Stock financial
"Represents shares received upon conversion of the Series A Preferred Stock"
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.
liquidation preference financial
"equal to the sum of the liquidation preference per share price of $10.00"
A liquidation preference is a rule that determines who gets paid first and how much they receive when a company is sold, goes bankrupt, or distributes its assets. It gives certain investors a priority claim—often returning their original investment plus any agreed multiple—before other owners receive money, which shapes how much common shareholders and founders ultimately get; think of it as a front-of-the-line pass that affects payout order and investor returns.
accrued and unpaid dividends financial
"and all accrued and unpaid dividends per share outstanding through August 10, 2027"
Accrued and unpaid dividends are dividend payments that a company has declared or owes to shareholders but has not yet actually paid out. For investors this matters because it represents cash they expect to receive—like a paycheck that’s been earned but not yet issued—and signals the company’s payment priorities and short-term cash health, which can affect shareholder returns and claims in cases like restructuring.
conversion price financial
"divided by a $4.00 conversion price per share"
The conversion price is the fixed price at which a convertible security, like a bond or preferred stock, can be exchanged for shares of common stock. It acts like a set rate that determines how many shares an investor can receive if they choose to convert their investment. This helps investors understand the value and potential benefits of converting their securities into company shares.
