What is EXTR institutional ownership?
This page tracks EXTR positions reported by institutional investment managers through SEC Form 13F. EXTREME NETWORKS INC (EXTR) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own EXTR?
InsiderSet currently tracks 332 institutional managers reporting EXTR 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 EXTR shareholders.
How much EXTR stock do institutions own?
Institutional investment managers disclosed approximately $4.08B in EXTR holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was EXTR institutional ownership last updated?
The latest EXTR 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.
Are institutional EXTR holdings real-time?
No. Form 13F data is not real-time. It represents positions reported by institutional investment managers as of the end of the reporting quarter. An institution may have changed its EXTR position after the reporting date.
Are institutions buying or selling EXTR?
Institutional buying and selling can be analyzed by comparing EXTR positions across consecutive 13F reporting periods. InsiderSet's EXTR Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View EXTR ownership changes.
