Context

• These transactions are tax-withholding-related (cashless surrender of vested restricted stock) and are routine administrative disposals; they do not necessarily indicate a change in the insider’s market view.
• For retail investors, purchases or open-market sales are typically more informative about sentiment; tax withholding events are common after awards vest.
