What is AAON institutional ownership?
This page tracks AAON positions reported by institutional investment managers through SEC Form 13F. AAON INC (AAON) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own AAON?
InsiderSet currently tracks 451 institutional managers reporting AAON 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 AAON shareholders.
How much AAON stock do institutions own?

When was AAON institutional ownership last updated?
The latest AAON institutional ownership data on InsiderSet is based on SEC Form 13F filings for the quarter ended June 30, 2026.
