Impact Evaluation

• Ownership Concentration: The filing indicates The Vanguard Group, Inc. no longer holds reportable beneficial ownership. However, the footnotes clarify this is due to a corporate realignment where subsidiaries will report separately.
• Transaction Significance: While the ownership drops to zero, the economic reality is likely a transfer of reporting responsibility rather than a liquidation of positions.

Market Impact Analysis
