What is ALTG institutional ownership?
This page tracks ALTG positions reported by institutional investment managers through SEC Form 13F. ALTA EQUIPMENT GROUP INC (ALTG) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own ALTG?
InsiderSet currently tracks 134 institutional managers reporting ALTG 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 ALTG shareholders.

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