Wartinbee William James III 4

What Happened
William James Wartinbee III, EVP, Global Sales & Service Operations at Gartner (IT), received vested restricted stock units (RSUs) that converted into 797 shares of common stock on February 9, 2026. Of those shares, 250 were withheld to cover applicable income/payroll taxes at a price of $159.75 per share, representing cash withheld of $39,938 (reported as $15,017 and $24,921 for the two withholding events). The RSU conversions are reported as derivative exercises (code M) with the tax withholding reported as disposals (code F). This was not an open-market purchase or sale but routine compensation vesting.

Context
These entries reflect routine RSU vesting and tax withholding rather than a buy or sell motivated by market views. The derivative (M) lines show RSUs converting to common stock; the F-code disposals are shares withheld to satisfy tax withholding obligations. For retail investors, purchases by insiders can be a stronger signal than routine vesting—this filing documents compensation-related vesting, not an open-market investment decision.
