Restricted Stock Units financial

"Represents Restricted Stock Units that were fully vested as of the grant date."

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.

withholding taxes financial

"shares of Class A Common Stock sold in the open market to pay for withholding taxes"

Withholding taxes are amounts a payer or government takes out of payments — such as wages, interest, or dividends — before the recipient gets the money, functioning like a cashier keeping part of a bill to pay taxes on your behalf. For investors this matters because it reduces the cash they actually receive, affects net returns and yield calculations, and may require additional paperwork or treaty claims to recover or offset the withheld amount against final tax bills.

Short Term Incentive Bonus Plan financial

"shares received in lieu of cash in accordance with the terms of the Issuer's 2026 Short Term Incentive Bonus Plan"
