COMPTON JENNIFER BRYNN 4

What Happened

• Jennifer Brynn Compton, Executive Vice President of Simmons First National Corp. (SFNC), had 1,986 restricted stock units (RSUs) vest on Feb 28, 2026. The RSUs converted one-for-one into 1,986 shares of SFNC common stock (reported as exercise/conversion, code M).
• To cover tax withholding, 840 of those shares were surrendered/withheld at $19.91 per share, generating $16,724 (reported as payment of tax liability, code F). That leaves a net of 1,146 shares retained from this vesting (1,986 − 840 = 1,146).
• This was a routine equity award vesting and associated tax-withholding transaction, not an open-market sale or purchase.

Key Details

• Transaction date: February 28, 2026; Form 4 filed March 3, 2026 (timely).
• Prices/values reported: tax withholding at $19.91/share → $16,724 total. The RSU-to-share conversion is non-cash (no exercise price).
• Shares acquired on vesting: 1,986. Shares withheld for taxes (disposed): 840. Net shares retained from this event: 1,146.
• Footnotes of note:
  • F1: RSUs convert into shares on a one-for-one basis.
  • F2: These RSUs vested on Feb 28, 2026.
  • F3: An additional 1,987 RSUs are scheduled to vest on Feb 28, 2027 (shares to be delivered within 30 days of vesting).
• Filing type/codes: M = exercise/conversion of derivative (RSU conversion), F = tax withholding. This was a company withholding to satisfy tax obligations (not an open-market sale).
• Shares owned after the transaction: the Form 4 did not disclose total SFNC shares owned by Ms. Compton after this event (we show net from this vesting only).

Context

• Vesting of RSUs with share-withholding for taxes is common and typically reflects compensation vesting rather than a deliberate buy or sell decision by the insider. Because the withholding was used to cover taxes, it should not be read as a bearish open-market sale.
• The filing appears timely (vest date Feb 28, 2026; Form 4 filed March 3, 2026).
