Context
Purchases coded P indicate acquisitions (open-market or private). The presence of a 10b5-1 trading plan means these trades may have been pre-scheduled under the plan adopted on 2025-11-12, which can limit how much the transactions reveal about current management views. Because the filer is an entity under common control rather than an individual executive, treat this as institutional/entity trading rather than a CEO/CFO personal decision.
