What is LDOS institutional ownership?
This page tracks LDOS positions reported by institutional investment managers through SEC Form 13F. LEIDOS HOLDINGS INC (LDOS) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own LDOS?
InsiderSet currently tracks 793 institutional managers reporting LDOS 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 LDOS shareholders.
How much LDOS stock do institutions own?

When was LDOS institutional ownership last updated?
The latest LDOS 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.
