Purchases make up the whole of the open-market record (5 purchases, €3.1M). 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 4 share grants.

On 28 May 2026 came the latest disclosure, a share grant in Vir Biotechnology, Inc. The last insider purchase was made public on 1 July 2024, 839 days ago. The median gap between a trade and its publication by SEC (Form 4) is 2 days. US insiders must file a Form 4 within two business days of a trade. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
