These shares are held in trust for the benefit of the reporting person and his children. The reporting person is the Trustee of the 2025 GRAT. | SEC |

The period balance: money in, money out
Across the Form 4 filings submitted between Aug 26, 2025 and Oct 19, 2026, Gartner, Inc. open-market activity adds up to 2 purchases worth $9.9M and 8 sales worth $1.5M. The net balance is $8.4M on the buy side.
Only codes P and S count, where an insider puts in or takes out their own money. A buying balance like Gartner, Inc.'s is the less common case in the S&P 500: its insiders are already paid in stock and still put in their own money. It is not a recommendation to buy or sell: it is what was filed.

How to read this data
None of the 8 sales in the table is flagged as scheduled (10b5-1 plan), the kind signed months ahead and executed automatically. Gartner's 2 open-market purchases (code P) are the rare signal: insiders are already paid in stock, so buying more means putting in their own money. The latest filing is from Oct 19, 2026, and a Form 4 arrives up to two business days after the trade.
13 of the 20 rows in the table carry footnotes from the Form 4 itself, folded into the code column and copied verbatim; a row with no footnote means the filing has none. Code J on its own only says "other transaction": which one it is, if the filing explains it, is in its footnote.
