How many institutions own INAB?
InsiderSet currently tracks 19 institutional managers reporting INAB 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 INAB shareholders.

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