What is NBR institutional ownership?
This page tracks NBR positions reported by institutional investment managers through SEC Form 13F. NABORS INDUSTRIES LTD (NBR) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own NBR?
InsiderSet currently tracks 240 institutional managers reporting NBR 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 NBR shareholders.
How much NBR stock do institutions own?
Institutional investment managers disclosed approximately $1.02B in NBR holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was NBR institutional ownership last updated?
The latest NBR 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 NBR 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 NBR position after the reporting date.
