Gilles Boisseau

All filings by Gilles Boisseau on record concern Mersen, in the capacity of senior executive. In total, 13 filings cover trades dated from 19 August 2021 to 16 May 2026.

Both buying and selling appear: 3 purchases worth €12k, against 3 sales worth €94k. Taken together, the sales exceed the purchases by €82k. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Other entries cover 4 share grants.

The median purchase comes to €54. Of 3 purchases, 3 formed part of a group of insiders buying within 30 days of each other. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.

The newest entry dates from 19 May 2026: a share grant, in Mersen. The most recent open-market purchase was published on 11 May 2023, 1,255 days ago. The median gap between a trade and its publication by AMF is 3 days. The regulation allows three business days to notify a trade (MAR article 19). Every figure here comes from the filings published by AMF and describes the past, not future prices; it is not investment advice.
