Frequently asked questions about STE
Who are the largest institutional holders of STE?
The largest institutional holders of STE reported in the latest SEC Form 13F filings include Blackrock, Inc., Vanguard Capital Management Llc, State Street Corp, Vanguard Portfolio Management Llc, and Massachusetts Financial Services Co. InsiderSet ranks institutional holders by their latest reported STE position.
What is STE institutional ownership?
This page tracks STE positions reported by institutional investment managers through SEC Form 13F. STERIS PLC (STE) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own STE?
InsiderSet currently tracks 823 institutional managers reporting STE 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 STE shareholders.
How much STE stock do institutions own?
Institutional investment managers disclosed approximately $20.05B in STE holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was STE institutional ownership last updated?
The latest STE 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 STE 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 STE position after the reporting date.
Are institutions buying or selling STE?
Institutional buying and selling can be analyzed by comparing STE positions across consecutive 13F reporting periods. InsiderSet's STE Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View STE ownership changes.
How has STE institutional ownership changed over time?
InsiderSet tracks STE institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
