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

The latest TSBK institutional ownership data on InsiderSet is based on SEC Form 13F filings for the quarter ended June 30, 2026.
