Context

• These are small, routine ESPP purchases rather than large directional trades by a major owner or a liquidity event. ESPP purchases often follow preset payroll/plan rules and don’t necessarily signal management’s private view of the company. The ADS conversion note (1 ADS = 5 common shares) is important when comparing to common‑share counts.
