(exechange) — Princeton Junction, New Jersey, October 9, 2023 — This news came on Columbus Day. Dennis Bertolotti, chief executive of Mistras, leaves his position. As announced by Mistras Group Inc. in a news release on Monday, October 9, 2023, Dennis M. Bertolotti leaves his post as chief executive officer at the provider of asset protection products, after about six years in the role, effective immediately.

Generally speaking, it raises questions when a CEO leaves his post abruptly.

Mistras will undertake a search for a successor.

Sotirios J. Vahaviolos is retiring as Executive Chairman after nearly 40 years of exceptional leadership and has been appointed Chairman Emeritus while remaining an active member of the Board of Directors. Succeeding him, the Board has appointed Manuel (Manny) N. Stamatakis as Chairman of the Board.

James J. Forese, the current Chairman of the Audit Committee, has been named Lead Director and Chairman of the Corporate Governance Committee.

Dennis Bertolotti’s duties as CEO will be taken over temporarily by Manuel N. (Manny) Stamatakis, currently Executive Officer at Capital Management Enterprises, Inc., as Interim Chief Executive Officer.

Already a director

Stamatakis has already been a member of the board of directors of Mistras. Generally speaking, most director-turned-CEO appointments occur following a sudden resignation of the outgoing CEO and signal a lack of preparedness on the company’s part to groom internal talent. Directors-turned-executives represent a blend of outsider and insider.

They don’t have the constraints of a pure insider when it comes to leading painful changes or making unpopular decisions, and they have more company knowledge than a pure outsider.

Having been a director, Stamatakis understands the expectations and dynamics of the board and has knowledge of Mistras’s organization, risk-management practices and strategy.

On its website, Mistras already lists Manny Stamatakis as Chairman Of The Board And Interim Chief Executive Officer (CEO).

“Next phase of growth and innovation”

Mistras did not give an explicit reason for Dennis Bertolotti’s departure from the CEO post. Mistras stated: “Mistras Group, Inc. (NYSE: MG), a leading “one source” multinational provider of integrated technology-enabled asset protection solutions, today announced a series of key leadership transitions that promise to guide the company into its next phase of growth and innovation.”

Precise information regarding Dennis Bertolotti’s future plans was not immediately available.


Mistras said: “Mr. Dennis M. Bertolotti will be departing Mistras as its CEO, and the Board has asked Mr. Stamatakis to serve as the Interim CEO until a successor CEO is found.”

The announcement follows a decline in Mistras Group Inc.’s share price of 75% since October 2018.
