Key Details
- Transaction date: 2026-05-21; reported filing date: 2026-05-26 (filed late relative to the 2-business-day Form 4 deadline).
- Sale: 688 shares at $53.26 per share; total value $36,641.
- Shares owned after transaction: not disclosed in the provided filing.
- Footnote: Sale was to satisfy tax withholding on RSU vesting ("sell to cover") — a mandatory company election, not necessarily an intentional market-timing sale.
- Transaction code: S (sale); footnote indicates tax-withholding/sell-to-cover (F1).
Context
Sell-to-cover transactions are common when restricted stock units vest and the issuer withholds shares to cover taxes; these are administrative and don't necessarily signal the insider's view of the company. The late filing means the disclosure came after the typical 2-business-day window for Form 4s, which can matter for transparency but does not change the nature of the transaction.
