IANNACONE NICOLE M 4

What Happened

• Nicole M. Iannacone, Senior EVP and Chief Legal Officer of Enterprise Financial Services Corp (EFSC), had 3,326 restricted stock units (RSUs) convert to common shares on Feb 24, 2026 (reported on a Form 4 filed Feb 26, 2026). Of those 3,326 shares, 1,466 were withheld to satisfy tax withholding at $57.57 per share, totaling $84,398. The net shares delivered to Iannacone were 1,860.
• This was a conversion/vesting of RSUs (derivative conversion), not an open-market purchase or voluntary sale — withholding to cover taxes is routine.
