Casteel Marty 4

What Happened
Marty Casteel, a director of Simmons First National Corp. (SFNC), received an award of 3,901 Restricted Stock Units (RSUs) on May 15, 2026. On the same date 975 of those RSUs vested and converted into 975 common shares (exercise/conversion). Simultaneously 975 shares were surrendered/disposed (reported at $0), consistent with withholding to cover taxes or similar obligations; the grant itself is reported at $0 (typical for RSU awards).

Key Details

• Transaction date: May 15, 2026 (Form 4 filed May 19, 2026). Filing appears timely.
• Grant: 3,901 RSUs (reported as Award/Grant (A)) at $0.00 per share.
• Vest/Conversion: 975 RSUs vested and converted to 975 shares (reported as M — exercise/conversion).
• Disposition: 975 shares reported as disposed at $0.00 — likely withholding for taxes.
• Shares owned after transaction: not specified in the provided summary of the filing.
• Relevant footnotes: RSUs convert one-for-one to common shares (F1, F2). Vesting schedule: 975 RSUs vested May 15, 2026; remaining tranches vest July 1, 2026; Oct 1, 2026; and Jan 4, 2027, with shares delivered within 30 days of vesting (F3–F5). Vested RSUs on May 15 are noted (F4).

Context

• RSUs are a form of equity compensation that convert into shares upon vesting; they are reported as grants (A) and conversions/exercises (M) when they vest and become actual shares.
• The zero-dollar amounts and matching conversion/disposition generally indicate shares were issued on vesting and some were withheld (not sold on market) to satisfy taxes or similar obligations — this is routine and not the same as an open-market sale.
• These entries are normal insider compensation transactions and do not, by themselves, indicate the insider's view of the stock.
