• Open-Market Dispositions:
  • 13,358 shares at a weighted-average price of $109.57 ($109.02 - $110.00).
  • 10,808 shares at a weighted-average price of $110.56 ($110.02 - $111.02).

Trading Significance

The trading significance is rated as Medium. Although the gross transaction value exceeds $4.2 million by the company's chief executive, the activity was conducted under a Rule 10b5-1 plan adopted more than 18 months prior and represents an exercise-and-sell strategy ahead of option expiration in early 2027, rather than discretionary open-market dumping of core equity holdings.
