[Form 4] GARTNER INC Insider Trading Activity

Rhea-AI Filing Summary

Gartner Inc. director Richard J. Bressler received an equity grant of 170 Common Stock Equivalents (CSEs) as compensation for board service. The CSEs were granted under the Gartner Long-Term Incentive Plan at a reference price of $154.79 per CSE.

Following this award, Bressler holds 21,363 CSEs in total. These CSEs convert into Gartner common stock when his continuous status as an outside director ends, or as otherwise provided in the Long-Term Incentive Plan. The filing reflects routine, compensation-related equity accumulation rather than an open-market share purchase.
