What is IOVA institutional ownership?
This page tracks IOVA positions reported by institutional investment managers through SEC Form 13F. IOVANCE BIOTHERAPEUTICS INC (IOVA) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own IOVA?
InsiderSet currently tracks 299 institutional managers reporting IOVA 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 IOVA shareholders.
How much IOVA stock do institutions own?

When was IOVA institutional ownership last updated?
The latest IOVA institutional ownership data on InsiderSet is based on SEC Form 13F filings for the quarter ended June 30, 2026.
