Context
Tax-withholding sales and trades under 10b5-1 plans are common and generally routine; they do not by themselves indicate a view on the company’s prospects. This report documents a disposition tied to RSU settlement and an established trading plan rather than an opportunistic open-market sale unrelated to compensation or plan rules.
