Key Details

  • Transaction date: 2026-03-01; filing date (Form 4): 2026-03-02 (timely).
  • Shares surrendered/disposed: 2,980 at $28.45 per share; total value reported: $84,781.
  • Transaction code/footnote: F — payment of exercise price or tax liability (share withholding to cover taxes).
  • Disposition type: shares surrendered to cover tax obligations (not an open-market sale).
  • Shares owned after the transaction: not specified in the provided filing excerpt.
  • Filing timeliness: filed the next day — no late filing flag indicated.

Context This is a routine tax-withholding event commonly seen after option exercises or restricted stock vesting. Because the shares were surrendered to cover taxes (a cashless-type settlement), it does not represent a typical sell signal driven by liquidity needs or market views. For investors, such transactions primarily reflect compensation mechanics rather than an insider's buy/sell sentiment.
