restricted stock units ("RSUs") financial

"Represents an award of 810 restricted stock units ("RSUs"), which vested on April 20, 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.

tax withholding obligations financial

"shares of Class A Common Stock were withheld by the Company for the purposes of satisfying tax withholding obligations"

Class A Common Stock financial

"406 shares of Class A Common Stock were withheld by the Company"

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.
