Monitor for 10b5-1 plan disclosures in upcoming 10-K or 8-K filings; absence of negative price reaction suggests market views this as routine. No immediate bearish signal given structural alignment with grants.

Executive Summary
Multiple Natera executives and a director sold shares in a coordinated open-market transaction totaling $1.8M across five insiders, including the CEO selling $1.15M.
