John Sheldon Serafini: trading record in brief

All filings by John Sheldon Serafini on record concern HawkEye 360, Inc. We count 2 filings, every one of them for a trade on 1 October 2026.

Sales make up the whole of the open-market record (1 sale, €1.2M). The rest of the record consists of 1 option exercise.

On 2 October 2026 came the latest disclosure, an option exercise for €19k in HawkEye 360, Inc. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
