Mistras Group Shares Jump Following Agreement With H.I.G. Capital to Go Private in $866 Million Deal

11:16 AM EDT, 09/18/2026 (MT Newswires) -- Mistras Group (MG) has agreed to be acquired by affiliates of alternative investment firm H.I.G. Capital in an all-cash transaction for an enterprise value of $866 million, including debt. Mistras' stock climbed 5.7% in Friday trade, taking its year-to-date gain to nearly 66%. Shareholders of Mistras will receive $20.35 a share in cash, representing a premium of about 8% to the company's 30-day volume-weighted average share price on Sept. 17. "We have created significant value through strong execution and we are excited to crystallize that value and work with H.I.G. to continue to invest in our people, drive innovation across our portfolio and broaden our reach to help more customers protect and maintain critical assets," Mistras Chief Executive Natalia Shuman said in a statement. The deal, which requires approval from Mistras' shareholders and regulatory clearance, is expected to close in late 2026 or early 2027. H.I.G. affiliates have already secured voting and support agreements in favor of the transaction with stockholders holding about a 31% stake in Mistras. "Mistras has built an impressive platform supported by a highly skilled workforce and longstanding customer relationships, and we look forward to bringing H.I.G.'s experience and resources to support the company's next phase of growth," H.I.G. Managing Director Matt Gullen said. Under the agreement, Mistras has a 40-day "go-shop" period until Oct. 27, allowing its board to seek and consider alternative offers. Following completion, the company will no longer trade on the New York Stock Exchange, according to the statement. Mistras raised its full-year 2026 outlook in August after it posted better-than-expected second-quarter results driven by demand growth in infrastructure, power generation and aerospace and defense end markets. Earlier in September, a consortium that includes the family investment firm of Dell Technologies (DELL) Chief Executive Michael Dell agreed to acquire and take Baldwin Insurance (BWIN) private in a deal worth $7.7 billion. In 2025, H.I.G. affiliates acquired and took private Microsoft Cloud and AI solutions provider Quisitive Technology Solutions for 169.1 million Canadian dollars ($120.8 million) and IT and cloud solutions company Converge Technology Solutions for an enterprise value of about 1.3 billion Canadian dollars.
