Context

• This is a sale by a large institutional/affiliate holder (10% owner reporting via its subsidiary and related entities), not a direct executive purchase — such sales can be routine portfolio or corporate-affiliate actions and do not necessarily signal management sentiment.
• Because only a straight sale is reported (no options or award), there is no complex derivative activity to explain here.
