John Mazarakis

John Mazarakis, listed as board member, has filed trades across 3 companies (mainly through SEC (Form 4)), most often in Chicago Atlantic Real Estate Finance, Inc., Vireo Growth Inc. and Chicago Atlantic BDC, Inc. Between 7 December 2021 and 27 August 2026, the trades on record add up to 25 filings.

On the open market, the record shows 13 purchases worth €4.0M and 1 sale worth €41k. Purchases outweigh sales by €4.0M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Outside the open market, there are 10 share grants. 2026 to date brings 5 purchases and no sales.

A typical purchase (the median) is worth €102k. Relative to company size, the median is 0.093% of market cap (5 purchases with a known value). Clusters matter here: 9 out of 13 purchases overlapped with buying by a colleague within 30 days. Purchases made close together by different insiders form what is called a cluster. Looking at 4 purchases old enough to measure, the stock rose over the following 90 days in 25% of cases; the median change was -3.6%. Past outcomes like these are no guarantee of what comes next.

On 28 August 2026 came the latest disclosure, an open-market purchase for €367k in Chicago Atlantic Real Estate Finance, Inc. 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. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
