What is GBX institutional ownership?
This page tracks GBX positions reported by institutional investment managers through SEC Form 13F. GREENBRIER COMPANIES INC (GBX) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own GBX?
InsiderSet currently tracks 263 institutional managers reporting GBX 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 GBX shareholders.
How much GBX stock do institutions own?

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