Restricted Stock Units financial

"The 13,476 restricted stock units vested and converted into 13,476 shares of DoubleVerify common stock on a one-for-one basis."

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

"To cover tax withholding obligations tied to this vesting, 7,453 shares of common stock were withheld rather than sold in the open market."

one-for-one basis financial

"The 13,476 restricted stock units vested and converted into 13,476 shares of DoubleVerify common stock on a one-for-one basis."

quarterly anniversary financial

"The remaining restricted stock units vest at a rate of 8.33% on each quarterly anniversary of the 2025 vesting date."

A quarterly anniversary marks the date that occurs every three months after a specific event, such as an investment or a business milestone. It is similar to a birthday that repeats four times a year, helping investors track the timing of important updates or changes. Recognizing these anniversaries allows investors to stay informed about progress and make timely decisions.
