• Shares owned after transaction: not specified in the filing.
• Footnotes: F1–F4 state RSUs convert 1-for-1 to SFNC common stock; the RSUs vested on July 1, 2026 (F2). Some related awards have future vesting dates and shares will be delivered within 30 days of vesting; certain events (retirement, death, disability) may trigger earlier vesting.
• Timeliness: Filing appears timely (transaction date 7/1/2026; filing 7/2/2026).

Context
Code M covers exercise or conversion of derivatives — in this case RSUs vesting and converting into company shares rather than a market sale. The $0.00 disposition lines are typical when a derivative is converted into shares with no cash consideration. This is an award/vesting event (not an open-market purchase or sale) and therefore should be interpreted as a receipt of company stock rather than a trading signal.
