Context
These entries reflect a derivative conversion/vesting event (PSUs converting to common stock) with company share withholding to cover taxes and subsequent open-market sales. Withholding of shares to satisfy taxes is a common net-settlement approach and the open-market sales indicate disposal of shares rather than a new purchase. The filing is factual and does not state Horich’s post-transaction holdings or motive.
