Vanguard Group Files Amendment 4 to Schedule 13G/A Reporting Zero Ownership in Inspire Medical Systems

The Vanguard Group filed Amendment 4 to Schedule 13G/A on March 27, 2026, reporting that it no longer holds any beneficial ownership in Inspire Medical Systems Inc. (INSP) common stock as of March 13, 2026. This represents a complete divestment from the previous position of 2,953,170 shares valued at approximately $272.4 million. The filing indicates that ownership is now 5% or less of the outstanding shares. The change results from an internal realignment at Vanguard on January 12, 2026, where certain subsidiaries or business divisions that formerly reported beneficial ownership with The Vanguard Group will now report separately on a disaggregated basis. Vanguard certifies that the securities were acquired and held in the ordinary course of business and not for influencing control of the issuer.
