What Happened

The issuer withheld shares to satisfy tax-withholding obligations. Separately, on 2026-03-16 he sold 180 shares in an open-market transaction at $200.80 per share, generating proceeds of $36,144.

Key Details

• Transactions reported:
  • 2026-03-13: 427 shares acquired via conversion of RSUs (M) at $0.00 (these represent vested RSUs; 1 RSU = 1 share) [Footnote F1, F3].
  • 2026-03-13: 427 shares disposed at $0.00 (shares surrendered/withheld by issuer to satisfy tax withholding) [Footnote F2].
  • 2026-03-16: 180 shares sold in open market (S) at $200.80; proceeds $36,144.
• RSU background: Grants were made on March 15, 2022 and vest at 20% per year on each anniversary (F4). Each RSU converts to one share on vesting (F3).
• Filing: Form 4 filed 2026-03-17 reporting transactions through 2026-03-16; no late filing is indicated in the data provided.
• Shares owned after the transactions: not specified in the excerpt provided.

Context

• The conversion (code M) reflects RSUs vesting rather than an option exercise requiring cash; the $0.00 price is normal for RSU vesting. The disposal of 427 shares at $0.00 indicates shares were surrendered/withheld to cover tax obligations (not a market sale by the insider). The separate sale of 180 shares was an open-market sale and produced modest proceeds; sales to cover taxes or withholding are routine and do not necessarily indicate a change in insider sentiment. Purchases (not present here) are generally more indicative of bullish signals.
