Vanguard Group Files Amendment Reporting Zero Ownership in Guardant Health After Internal Reorganization

The Vanguard Group has filed an amended Schedule 13G/A reporting that it no longer holds any shares of Guardant Health Inc. (ticker: GH) common stock as of March 13, 2026. This filing represents a significant change from the previous report where Vanguard held 12,160,768 shares valued at approximately $1.24 billion. The zero ownership position results from an internal realignment that occurred on January 12, 2026, where certain subsidiaries and business divisions of The Vanguard Group, Inc. that formerly had beneficial ownership with the parent company will now report ownership separately on a disaggregated basis. The filing indicates that Vanguard's ownership has fallen below 5% of the outstanding shares, and the company certifies that the securities were acquired and held in the ordinary course of business without intent to influence control of the issuer. The amendment was filed on March 27, 2026, by Ashley Grim, Head of Global Fund Administration.
