Purchases make up the whole of the open-market record (1 purchase, €35k). A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Other entries cover 9 share grants.

This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
