Muneer A. Satter

Filings by Muneer A. Satter span 5 companies, the busiest being Whitehawk Therapeutics, Inc., Immunic, Inc. and Annexon, Inc. Over a trading history stretching from 15 March 2017 to 28 May 2026, the count stands at 69 filings.

On the open market, the record shows 64 purchases worth €93.5M and 3 sales worth €3.5M. Taken together, the purchases exceed the sales by €90.0M. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Since January 2026: 1 purchase and no sales on the market.

A typical purchase (the median) is worth €37k. Clusters matter here: 25 out of 61 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 6 purchases old enough to measure, the stock rose over the following 90 days in 83% of cases; the median change was +13.6%. They describe history only and say nothing certain about the share price ahead.

Most recently, on 29 May 2026, the filings show an open-market purchase worth €2.9M in Annexon, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 1 day. Section 16 rules allow two business days to file each Form 4. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
