Context
As a reported 10% owner, Scott is a large shareholder; such sales can reflect diversification, estate or tax planning, or routine liquidity needs rather than a view on the company. This filing documents a straightforward open-market sale—no option exercise, gift, or tax-withholding transaction was reported.
