Vincent Kamel

All filings by Vincent Kamel on record concern Carbios, in the capacity of chief executive. The record holds 10 filings, for trades running from 1 August 2025 to 29 August 2025.

Both buying and selling appear: 5 purchases worth €408k, against 5 sales worth €530k. Netting one side against the other leaves €121k of net selling. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant.

Half of the purchases are above €74k and half below. None of the 5 purchases we analysed coincided with buying by another insider of the same company within 30 days. For 5 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 20% of cases, with a median move of -16.2%. This is a record of the past, not a forecast.

The newest entry dates from 3 September 2025: an open-market purchase of €37k, in Carbios. Typically, a trade is published a median of 3 days after it takes place. 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.
