What is ONEW institutional ownership?
This page tracks ONEW positions reported by institutional investment managers through SEC Form 13F. ONEWATER MARINE INC-CL A (ONEW) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own ONEW?
InsiderSet currently tracks 95 institutional managers reporting ONEW 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 ONEW shareholders.
How much ONEW stock do institutions own?

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