  • Prices reported: $271.77 per share for both entries.
  • Shares withheld/disposed: 218 and 625 (total 843).

Context This transaction is a cashless tax-withholding event associated with equity compensation vesting, a routine administrative step that does not necessarily signal the insider's view of the company's prospects. It differs from an open-market sale or a purchase because shares were surrendered to cover taxes rather than sold for proceeds to the insider.
