How many institutions own FISN?
InsiderSet currently tracks 24 institutional managers reporting FISN 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 FISN shareholders.

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