No insider sold shares on the market over the period. Instead, the filings list 6 purchases totalling €16.1M, made by 6 insiders. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant.

In all, 6 purchases were made within 30 days of a purchase by another insider of the company. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase. The most recent open-market purchase was published on 8 June 2026, 132 days ago. Filings reach the SEC (Form 4) feed a median of 4 days after the trade. For comparison, the SEC allows two business days to file a Form 4.
Compared with its exchange (5,813 companies, median 19 filings), a count of 14 filings is below the norm. Our records for Quantinuum Inc. go back to 2026, with 6 purchases and no sales on the open market in total.
