restricted stock units financial

"The shares of Common Stock were acquired upon the vesting of certain restricted stock units previously granted"

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 obligation financial

"The shares of Common Stock were withheld to satisfy the reporting person's tax withholding obligation"

derivative security financial

"Exercise or conversion of derivative security"

A derivative security is a financial contract whose value comes from the price or performance of something else, such as a stock, bond, commodity, or market index. For investors it acts like an insurance policy or a wager: it can be used to protect against losses, lock in prices, or amplify gains and losses, so it can change a portfolio’s risk and potential return without owning the underlying asset directly.

What insider transactions did NETSCOUT (NTCT) CFO Anthony Piazza report?

Anthony Piazza reported RSU vesting into 2,000 NETSCOUT shares and a related tax withholding of 589 shares. These transactions are compensation-related, not open-market trades, and reflect routine equity award vesting for the company’s EVP & Chief Financial Officer.

Did NETSCOUT (NTCT) CFO Anthony Piazza buy or sell shares on the market?

The filing shows no open-market buying or selling by Anthony Piazza. Shares were acquired through restricted stock unit vesting, and 589 shares were withheld by the company to satisfy tax obligations, which is different from discretionary market sales or purchases.

How many NETSCOUT (NTCT) shares does CFO Anthony Piazza hold after these transactions?

After the reported transactions, Anthony Piazza directly holds 27,754 shares of NETSCOUT Common Stock. This balance reflects the 2,000 shares received from RSU vesting, net of the 589 shares withheld to meet associated tax withholding requirements on June 15, 2026.

What price was used for the NETSCOUT (NTCT) tax withholding shares?

The 589 shares withheld for taxes were valued at $41.42 per share, which the filing identifies as the closing price of NETSCOUT’s Common Stock on June 12, 2026. That price was used solely to calculate the tax withholding amount for the vesting.

What do the restricted stock unit transactions mean for NETSCOUT (NTCT) investors?

The transactions reflect routine equity compensation for NETSCOUT’s CFO, with RSUs converting into 2,000 Common shares. Because the only disposition was 589 shares withheld for taxes, the filing signals standard compensation mechanics rather than a discretionary insider sale in the market.
