Context
As a 10% owner rather than a disclosed executive-trade only, these sales were executed under an established 10b5-1 plan, which commonly indicates pre-scheduled, automated selling. Sales do not necessarily signal a change in sentiment about the company; they often reflect diversification, tax planning, or liquidity needs.
