Smart Money Convergence

MG does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.

13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.

Mistras Group issued a press release on August 10, 2026, reporting its second-quarter results for the period ended June 30, 2026, and filed this 8-K to document that release. The filing explains that the company uses non-GAAP measures such as Adjusted EBITDA, free cash flow, net debt, and income from operations before special items, with reconciliations included in the press release tables. The excerpt doesn't include actual revenue or profit figures, so it reads as a standard earnings disclosure rather than a full results announcement.
