Arnaud Dartois

Arnaud Dartois (chief executive) discloses dealings in Coretech 5 to AMF. We count 11 filings; the first trade dates from 14 May 2025 and the latest from 27 June 2026.

In open-market terms, that means 5 purchases worth €90k on one side and 2 sales worth €35k on the other. No amount is published for 1 filing, which the totals therefore leave out. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Since January 2026: 1 purchase and no sales on the market.

A typical purchase (the median) is worth €28k. Of 4 purchases, 3 formed part of a group of insiders buying within 30 days of each other. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

The record was last updated on 13 August 2026 with an open-market purchase in Coretech 5. Between a trade and the moment it shows up on AMF, the median delay is 4 days. The legal deadline for notifying a trade is three business days (MAR article 19). This summary is built from AMF disclosures alone and does not predict where the share price will go.
