How many institutions own PLBC?
InsiderSet currently tracks 104 institutional managers reporting PLBC 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 PLBC shareholders.

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