Sylvie GUIGANTI: trading record in brief

This profile gathers the share dealings of Sylvie GUIGANTI in Mersen, where the filings describe the role as senior executive. Over a trading history stretching from 10 May 2023 to 16 May 2026, the count stands at 5 filings.

The latest filing, published on 19 May 2026, reports a share grant in Mersen. Between a trade and the moment it shows up on AMF, the median delay is 3 days. The regulation allows three business days to notify a trade (MAR article 19). A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by AMF and describes the past, not future prices; it is not investment advice.
