On the open market, the record shows 1 purchase worth €303k and 7 sales worth €29.4M. The net balance comes to €29.1M on the selling side.

The latest filing, published on 21 May 2025, reports a transaction in Avantor, Inc. The most recent open-market purchase was published on 17 November 2022, 1,453 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. For comparison, the SEC allows two business days to file a Form 4. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
