Context

• This purchase was executed through the company’s ESPP/related plans (administrator purchase and trust holdings), meaning it was made according to plan terms rather than a discretionary open‑market trade. Purchases via ESPPs often reflect routine participation in company compensation plans; they provide direct ownership but are not a definitive signal of future performance.
