What is TWST institutional ownership?
This page tracks TWST positions reported by institutional investment managers through SEC Form 13F. TWIST BIOSCIENCE CORP (TWST) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own TWST?
InsiderSet currently tracks 355 institutional managers reporting TWST 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 TWST shareholders.
How much TWST stock do institutions own?

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