What is ECL institutional ownership?
This page tracks ECL positions reported by institutional investment managers through SEC Form 13F. ECOLAB INC (ECL) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own ECL?
InsiderSet currently tracks 1,685 institutional managers reporting ECL 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 ECL shareholders.

Institutional investment managers disclosed approximately $65.19B in ECL holdings for Q3 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was ECL institutional ownership last updated?
The latest ECL institutional ownership data on InsiderSet is based on SEC Form 13F filings for the quarter ended September 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.
