Charles e. Mather IV: trading record in brief
Charles e. Mather IV (board member) discloses dealings in 2 companies, chiefly Hyperion Defi, Inc. and Tonix Pharmaceuticals Holding Corp. We count 27 filings; the first trade dates from 26 April 2013 and the latest from 21 April 2025.
The open-market record is one-sided, with 13 purchases worth €110k and not one sale. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Besides market trades, the filings include 9 share grants and 4 option exercises.
Half of the purchases are above €11k and half below. Of 8 purchases, 4 formed part of a group of insiders buying within 30 days of each other. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. Looking at 12 purchases old enough to measure, the stock rose over the following 90 days in 33% of cases; the median change was -21.0%. These figures describe past trades and do not predict future prices.
Most recently, on 29 April 2025, the filings show a share grant in Hyperion Defi, Inc. The most recent open-market purchase was published on 30 May 2023, 1,259 days ago. Typically, a trade is published a median of 2 days after it takes place. US insiders must file a Form 4 within two business days of a trade. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
