Mathieu Planche

Mathieu Planche, listed as chief executive, appears in our data through filings on Witbe shares, published by AMF. We count 7 filings; the first trade dates from 19 September 2022 and the latest from 20 May 2025.

The open-market record is one-sided, with 7 purchases worth €31k and not one sale. The totals exclude 2 filings filed without an amount. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. So far in 2025, the count stands at 5 purchases and no sales.

A typical purchase (the median) is worth €7,456. 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 -17.8%. Past outcomes like these are no guarantee of what comes next.

The record was last updated on 21 May 2025 with an open-market purchase (€7,868) in Witbe. The median gap between a trade and its publication by AMF is 3 days. The legal deadline for notifying a trade is three business days (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.
