Both buying and selling appear: 12 purchases worth €495k, against 2 sales worth €50k. Purchases outweigh sales by €445k. 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 11 share grants and 6 option exercises.

A typical purchase (the median) is worth €33k. Clusters matter here: 2 out of 12 purchases overlapped with buying by a colleague within 30 days. Purchases made close together by different insiders form what is called a cluster.

The latest filing, published on 5 August 2025, reports a share grant in RPC Inc. The last insider purchase was made public on 7 August 2019, 2,631 days ago. The median gap between a trade and its publication by SEC (Form 4) is 2 days. For comparison, the SEC allows two business days to file a Form 4. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
