Waleed H. Hassanein

Waleed H. Hassanein is a declared insider of TransMedics Group, Inc. (chief executive), with filings sourced from SEC (Form 4). Between 6 May 2019 and 10 July 2026, the trades on record add up to 126 filings.

Both buying and selling appear: 4 purchases worth €2.6M, against 96 sales worth €44.6M. Sales outweigh purchases by €42.1M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The rest of the record consists of 4 share grants and 20 option exercises.

Half of the purchases are above €756k and half below. Across 4 purchases, this insider has always bought alone, with no colleague buying within 30 days.

Most recently, on 14 July 2026, the filings show a share grant in TransMedics Group, Inc. The most recent open-market purchase was published on 18 November 2025, 340 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. US insiders must file a Form 4 within two business days of a trade. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
