KEENE S TURNER 4

What Happened

• Keene S. Turner, Chief Financial Officer of Enterprise Financial Services Corp. (EFSC), converted/exercised 4,989 derivative units into common stock on Feb 24, 2026. The filing shows an exercise/conversion price of $0.00 for those units.
• As part of the same transaction, 2,169 shares were withheld to satisfy tax withholding obligations at a reported per-share value of $57.57, for a total withholding value of $124,869. That leaves a net of 2,820 shares issued to Mr. Turner (4,989 converted − 2,169 withheld).

Key Details

• Transaction date: 2026-02-24; Form 4 filed: 2026-02-26 (appears timely).
• Reported amounts:
  • Conversion/exercise: 4,989 shares (reported consideration $0.00).
  • Tax withholding: 2,169 shares @ $57.57 = $124,869 (Disposition code F).
  • Net shares received: 2,820 (4,989 − 2,169).
• Relevant footnotes:
  • F1: Withholding of stock to satisfy tax withholding obligation on issuance of common stock.
  • F9 (appears in filing): RSU vesting schedule includes Feb 24, 2026 (vesting may explain the conversion/issuance).
• Shares owned after the transaction are not included in the excerpt provided.

Context

• This is primarily an issuance/vesting-type event (conversion of derivative/RSU units) with a routine tax-withholding share surrender rather than an open-market sale or new cash purchase. The withholding is a common, administrative step to cover tax liabilities and does not necessarily indicate a change in insider sentiment.
• Because part of the converted shares were withheld rather than sold on the market, this is effectively a net acquisition of shares by the insider (2,820 shares), though no cash purchase occurred.
