Restricted Stock Units financial

"in connection with the vesting of 39,889 Restricted Stock Units on May 15, 2026"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

tax withholding obligations financial

"withheld by the Company for the purposes of satisfying tax withholding obligations"

Class A Common Stock financial

"17,486 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.

closing price financial
