Equity Research Analyst

TL;DR: Insider sold a total of 7,043 shares at roughly $25.34–$25.98, a minor reduction in direct holdings with limited apparent market impact.

The Form 4 shows two disposal entries totaling 7,043 shares on 08/13/2025 with weighted-average prices and ranges disclosed. Share count declines from 121,318 to 116,175 are explicit. Given the disclosed amounts and lack of other material events in the filing, these transactions appear to be routine monetization under a trading plan rather than event-driven insider activity.
