How many institutions own PASG?
InsiderSet currently tracks 29 institutional managers reporting PASG holdings in the latest available 13F data. This count reflects institutions included in the SEC Form 13F filings analyzed by InsiderSet and should not be interpreted as the total number of PASG shareholders.

The latest PASG institutional ownership data on InsiderSet is based on SEC Form 13F filings for the quarter ended June 30, 2026.
