What is LTBR institutional ownership?

How many institutions own LTBR?
InsiderSet currently tracks 124 institutional managers reporting LTBR 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 LTBR shareholders.

When was LTBR institutional ownership last updated?
The latest LTBR institutional ownership data on InsiderSet is based on SEC Form 13F filings for the quarter ended June 30, 2026. Form 13F filings are generally reported after the quarter ends, so the holdings shown represent the latest publicly disclosed positions rather than real-time institutional holdings.
