How many institutions own NGNE?
InsiderSet currently tracks 111 institutional managers reporting NGNE 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 NGNE shareholders.
