Open-market activity splits into 26 purchases totalling €8.0M and 4 sales totalling €2.7M; 18 insiders sit on the buying side and 3 insiders on the selling side. No amount is published for 12 filings, which the totals therefore leave out. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Biggest ticket of the year: €3.4M, bought by Charles Edelstenne and made public on 2 September 2026 (0.012% of market cap). Among those who bought: 11 senior executives, 6 board members and 1 chief executive.

In all, 7 purchases were made within 30 days of a purchase by another insider of the company. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. The most recent open-market purchase was published on 2 September 2026, 45 days ago. Typically, a trade is published a median of 3 days after it takes place. The regulation allows three business days to notify a trade (MAR article 19).

For context, the typical company on the same exchange (median of 316 companies) published 6 filings over the same period, against 30 filings here. Since 2021, the database holds 76 purchases and 199 sales by insiders of the company.
