Insights

Securities Analyst

TL;DR: Routine Form 144 reporting an exercised option and planned brokered sale; several sizable insider-related sales occurred over the past three months.

The filing documents a stock option exercise on 09/16/2025 producing 25,000 shares that are proposed for sale the same day through Morgan Stanley Smith Barney on the NYSE for $1,791,487.50. The historical sale entries show meaningful volumes sold by the Yeaman Family Trust across June to August 2025, totaling 92,366 shares with aggregate gross proceeds disclosed.
