All filings by Manuel N. Stamatakis on record concern Mistras Group, Inc., in the capacity of board member. The record holds 60 filings, for trades running from 8 October 2009 to 4 March 2026.

In open-market terms, that means 18 purchases worth €1.8M on one side and 1 sale worth €183k on the other. The net balance comes to €1.6M on the buying side. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Outside the open market, there are 41 share grants.

Half of the purchases are above €78k and half below. Of 16 purchases, 10 formed part of a group of insiders buying within 30 days of each other. Purchases made close together by different insiders form what is called a cluster. Looking at 17 purchases old enough to measure, the stock rose over the following 90 days in 53% of cases; the median change was +2.5%. They describe history only and say nothing certain about the share price ahead.

The newest entry dates from 10 March 2026: a share grant of €11k, in Mistras Group, Inc. The latest purchase dates back some time: it was published 520 days ago, on 6 June 2025. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. For comparison, the SEC allows two business days to file a Form 4. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
