CFO Paul "Pete" Peterik to Retire

The Company announced that its Chief Financial Officer, Paul "Pete" Peterik, has decided to retire. Mr. Peterik has agreed to remain with the Company in his current role until his successor is named. The company has initiated a search for his replacement, and once a new CFO is in place, Mr. Peterik will remain available to the Company for a period of time as a non-employee consultant on an as-needed basis. Mistras Chairman and Chief Executive Officer, Dr. Sotirios Vahaviolos, stated that, "We are extremely grateful for all Pete has done for us during his tenure at Mistras, particularly the instrumental role he played helping launch the Company's successful initial public offering last October. We wish Pete all the best in his retirement."

Automatic Extension of Lock-Up Period

Mistras also announced that the lock-up agreements entered into with its underwriters in conjunction with its initial public offering will automatically be extended 18 days beyond the Company's April 7, 2010 earnings release. The lock-up period was originally due to expire on April 5, 2010, but Mistras' underwriting agreement and lock-up agreements with directors, officers and certain shareholders of Mistras provide for an automatic extension due to the timing of Mistras' earnings press release. Therefore, the first sales of shares restricted by the underwriters' lock-up may now take place on Monday, April 26, 2010.
