In open-market terms, that means 1 purchase worth €88k on one side and 2 sales worth €1.9M on the other. Sales outweigh purchases by €1.8M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Outside the open market, there are 2 share grants and 4 option exercises. Since January 2026: no purchases and 2 sales on the market.

The latest filing, published on 12 March 2026, reports an open-market sale of €1.2M in NewAmsterdam Pharma Co N.V. The most recent open-market purchase was published on 21 February 2024, 970 days ago. Typically, a trade is published a median of 2 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
