Justin Mateen: trading record in brief

All filings by Justin Mateen on record concern American Bitcoin Corp. In total, 4 filings cover trades dated from 3 March 2026 to 6 August 2026.

On the market, this insider has only ever bought: 3 purchases, €3.3M in total. 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 1 option exercise.

The median purchase comes to €869k. Clusters matter here: 1 out of 3 purchases overlapped with buying by a colleague within 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

The latest filing, published on 7 August 2026, reports an open-market purchase of €802k in American Bitcoin Corp. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. The legal deadline for a Form 4 is two business days after the transaction.
