No open-market purchase appears, only 1 sale worth €300.3M. Other entries cover 3 share grants and 5 option exercises.

On 19 May 2025 came the latest disclosure, an option exercise in Frontier Group Holdings, Inc. Typically, a trade is published a median of 2 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
