TL;DR: Routine insider sale and purchase resulting in a modest net increase of 300 shares; not a clearly material signal.

The filing documents a small block sale of 433 shares on 09/30/2025 and a purchase of 300 shares on 10/01/2025 for John Birchall, a Managing Director and officer. The sale price is reported as the average of the high and low on 09/30/2025 ($301.28) and the purchase price uses the average September closing price ($287.18). Beneficial ownership moves from 6,267 shares after the sale to 6,567 shares after the purchase.
