Insights

Equity compensation analyst

CEO’s Form 4 shows routine RSU vesting with tax withholding, not an open-market trade.

The filing shows Anil K. Singhal receiving 10,800 shares of Common Stock from vested restricted stock units. This is coded as an M transaction, meaning a derivative conversion, and represents standard equity compensation rather than a discretionary stock purchase.

To satisfy tax obligations from the vesting, 4,195 shares were withheld, coded as an F transaction for tax-withholding disposition, using a reference price of $41.42 per share. There is no indication of an open-market sale.

After these entries, Singhal holds 449,275 shares directly and 1,443,960 shares indirectly through trusts. The pattern is a typical grant-and-tax-withholding structure, with no strong directional signal about his view of NETSCOUT SYSTEMS INC stock.
