restricted stock units ("RSUs") financial
"Represents the grant of restricted stock units ("RSUs"). The RSUs vest 1/3rd on each of April 20, 2027"
Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.
Convertible Promissory Note financial
"Reflects a convertible note that is convertible into shares of Common Stock of the Issuer."
A convertible promissory note is a loan a company takes now that can later be turned into shares instead of being repaid in cash. Think of it as lending money with the option to accept ownership in the business down the road; that matters to investors because it affects who gets paid first, how much ownership existing shareholders keep, and the company’s future valuation and cash needs. Terms such as conversion price, interest and maturity determine the financial impact.
Class B Common Stock financial
"Each share of Class B Common Stock was reclassified into one share of Common Stock"
A class B common stock is one of multiple types of a company’s ordinary shares that carries specific rights—often different voting power or dividend priority—compared with other classes. For investors it matters because those differences affect how much influence you have over company decisions, the income you might receive, and how freely the shares trade; think of it like owning a car with different keys: some keys let you start the engine and open the trunk, others only unlock the door.
Series C Preferred Stock financial
"The Series A-3 Preferred Stock, Series A-4 Preferred Stock and Series C Preferred Stock are convertible"
A Series C preferred stock is a specific class of ownership issued during a later funding round that gives holders priority over common shareholders for getting paid and receiving dividends, like having a reserved lane in traffic when money is distributed. It often includes agreed rights such as a fixed payout, protection against dilution, and the option to convert into common shares, so investors treat it as a mix of safety and upside potential.
