Restricted Stock Units ("RSUs") financial
"These Restricted Stock Units ("RSUs") were granted to the Reporting Person on February 25, 2026"
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.
1-for-10 reverse stock split financial
"adjusted to account for rounding as a result of a 1-for-10 reverse stock split effected by the Issuer"
Class B Common Stock financial
"The shares of Class B Common Stock are convertible into shares of Class A 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.
Option (Right to Buy) financial
"Option (Right to Buy) ... underlying security title: Class A Common Stock"
beneficially owned financial
"The number of shares beneficially owned by the Reporting Person has been adjusted"
Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.
