HALL EUGENE A 4

What Happened
Eugene A. Hall, Gartner's Chairman and CEO, had restricted stock units (RSUs) vest and convert into common shares on Feb 9, 2026. Two RSU installments converted one-for-one into a total of 16,729 shares (9,195 and 7,534). To cover withholding obligations, 6,682 of those shares (3,673 and 3,009) were surrendered at $159.75 per share, generating tax withholding values of $586,762 and $480,688 (total ≈ $1,067,450). The remaining 10,047 shares were retained by Hall. These entries are RSU vesting/conversion and tax-withholding actions (not open-market sales).

Key Details

• Tax withholding: 3,673 shares and 3,009 shares withheld at $159.75 each to satisfy income/payroll taxes (F code); total withholding ≈ $1,067,450.
• Net new shares retained by insider: 10,047 shares (16,729 vested − 6,682 withheld).
• Shares owned after transaction: not specified in the excerpted filing.
• Footnotes: vesting represents the 2026 installment from two separate RSU grants (one granted beginning Feb 9, 2023; the other beginning Feb 9, 2024). Withholding was used to pay applicable taxes.

Context

• This was a routine vesting of RSUs and a cashless-type settlement to cover withholding — common and administrative in nature, not an open-market sale.
• Such transactions are generally not a direct signal of the insider’s view on the stock; purchases or open-market sales provide clearer trading signals.
• The filing shows conversion of derivative awards (RSUs) and share-withholding for taxes, which is standard practice on vesting dates.
