Restricted Stock Units ("RSUs") financial

"The shares reported in this transaction represent Restricted Stock Units ("RSUs")."

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.

Class A common stock financial

"Each RSU represents the contingent right to receive one share of the Issuer's Class A common stock."

Class A common stock is a category of a company’s shares that carries a specific set of ownership rights—most commonly defined voting power and claims on dividends—set out in the company’s charter. For investors it matters because the class determines how much influence you have over corporate decisions, the share’s likely dividend and trading behavior, and how it compares in value to other share classes, like choosing a particular seat with different privileges at the company’s decision-making table.

Epstein Family Revocable Trust financial

"These shares are held by the Epstein Family Revocable Trust."
