Chicago Atlantic REFI: executive chairman buys ~$429k
John Mazarakis reported a direct REFI purchase of about 40,181 shares at $10.67 on August 26, 2026 - a single-filer Strong-band buy that still has to be read next to, not as, the company's pending merger filings.
What happened
On August 26, 2026, Chicago Atlantic Real Estate Finance, Inc. (REFI) Executive Chairman John Mazarakis reported a direct purchase of about 40,181 shares at $10.67, a notional of roughly $429,000. The Form 4 is dated August 28. Greediness on the export row was 86: Strong band.
No other REFI insider appears as a same-window open-market buyer in this export. This is a single-filer print, closer to the First Merchants CEO case study than to a director cluster.
Why it matters
Chairman title, six-figure cash, and direct ownership are enough to push a clean code P filing into the Strong band without a cluster. That is useful as a reading-priority flag. It is not a size-versus-Jefferies comparison: $429,000 is meaningful and still an order of magnitude below the JEF CEO lot.
REFI has separately disclosed a proposed merger with Chicago Atlantic BDC, Inc. (LIEN). Merger mechanics live in 8-K and proxy materials. The Form 4 does not incorporate those documents and does not state that the purchase is about the deal.
Key signals
- Title: Executive Chairman.
- Economics: ~$429,000 at a reported $10.67 - consistent with cash open-market, pending EDGAR confirmation of code P.
- Ownership: Direct.
- Urgency: trade August 26, filing August 28 - inside the two-business-day window.
Related-issuer noise: LIEN's president also reported small purchases in this export window. Do not stitch REFI and LIEN into one cluster. They are different reporting companies even if they sit in the same corporate family and even if a merger is pending.
Context
Mortgage REITs and specialty lenders often have Form 4 tapes that mix compensation, dividend-reinvestment, and genuine open-market lots. Read the transaction code and any 10b5-1 box. A chairman buy during a deal process is legally ordinary and informationally ambiguous: insiders can buy, can be in a blackout, or can be acting on a personal schedule.
If you research the merger, research it from the primary deal filings. If you research the buy, research it from the Form 4. Mixing the two into one "they know something" sentence is how Form 4 commentary goes wrong.
Final takeaway
Queue the REFI chairman Form 4 as a Strong-band open-market buy: verify code, size, and direct ownership, keep the merger tape in a separate folder, and do not treat 86 as a forecast for REFI or for the deal. Open the live feed at /app?band=strong&q=REFI.
