Both buying and selling appear: 2 purchases worth €1.1M, against 7 sales worth €13.3M. The net balance comes to €12.1M on the selling side. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. The rest of the record consists of 10 share grants and 1 option exercise. So far in 2026, the count stands at no purchases and 7 sales.

Most recently, on 11 March 2026, the filings show an open-market sale worth €724k in Perimeter Solutions, SA. The latest purchase dates back some time: it was published 3,174 days ago, on 13 February 2018. The median gap between a trade and its publication by SEC (Form 4) is 2 days. Section 16 rules allow two business days to file each Form 4. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
