FAQ

Does Vanguard own any AEHR shares after this amendment?

No. The Schedule 13G/A states Amount beneficially owned: 0 and Percent of class: 0% as reported on 03/13/2026. The filing attributes this to an internal realignment effective 01/12/2026.

What caused Vanguard to report zero ownership for AEHR?

An internal realignment on 01/12/2026 led Vanguard to disaggregate reporting among subsidiaries. The filing cites SEC Release No. 34-39538 as the basis for separate reporting by those entities.

Will other Vanguard entities file ownership reports for AEHR?

Possibly. The amendment states certain subsidiaries now report beneficial ownership separately. Related subsidiaries or business divisions may file their own Schedule 13G/A or 13D filings to reflect any holdings.

What date does the filing use for the reported ownership position?

The Schedule 13G/A lists the reporting date as 03/13/2026 and includes a signature dated 03/26/2026 from Vanguard's Head of Global Fund Administration, certifying the amendment.

Does this filing change who receives dividends or sale proceeds for AEHR shares?

The filing states Vanguard, including its managed accounts, has the right to receive or direct dividends or sale proceeds for the securities reported; however, it also states no other person's interest exceeds 5% in the reported holdings.
