Context This filing reflects sales by a large institutional/beneficial owner (a 10% owner reported via trustee entities), not an executive officer’s direct trading signal. The footnotes indicate the reported prices are weighted averages across multiple trades and provide ranges; the filer says it can supply per-trade price details to the SEC or issuer on request. Sales by 10% holders can be part of portfolio management and don't necessarily indicate company-specific views.
