.Item 2.02.  Results of Operations and Financial Condition

On March 4, 2026, Mistras Group, Inc. (the "Company," "we," "us" and "our") issued a press release announcing the financial results for our fourth quarter and year ended December 31, 2025. A copy of the press release is attached as Exhibit 99.1 to this report.

Disclosure of Non-GAAP Financial Measures

In the press release attached, the Company uses the terms “Adjusted EBITDA,” “free cash flow,” "net debt" and "net income before special items," which are not measures of financial performance under U.S. generally accepted accounting principles (“GAAP”). The tables to the press release include reconciliations of these non-GAAP financial measures to the most comparable financial measure under GAAP. Also, in the tables to the press release, the non-GAAP financial measures "Segment and Total Company Income (Loss) before Special Items” (which includes operating income (loss) before special items) are presented and reconciled to financial measures under GAAP within the table "Segment and Total Company Income (Loss) from Operations (GAAP) to Income (Loss) from Operations before Special Items (Non-GAAP)." The non-GAAP financial measure "Diluted EPS excluding Special Items," is presented and reconciled to the financial measure under GAAP within the table "Net Income (Loss) (GAAP) and Diluted EPS (GAAP) to Net Income Excluding Special Items (non-GAAP) and Diluted EPS Excluding Special Items (Non-GAAP)." Information about these non-GAAP financial measures are included in the press release.

Our management uses and provides these non-GAAP financial measures as a measure of operating performance and liquidity to assist in comparing performance from period to period on a consistent basis, as a measure for planning and forecasting overall expectations for the Company and for evaluating actual results against such expectations. Adjusted EBITDA and free cash flow are also performance evaluation metrics used to determine incentive compensation for the Company's executive officers.

We believe that investors and other users of the financial statements benefit from the presentation of these non-GAAP financial measures because they provide additional metrics to compare the Company's operating performance and liquidity on a consistent basis and measure underlying trends and results of the Company's business. Adjusted EBITDA and operating income before special items assist in evaluating our operating performance because they remove the impact of certain items that management believes do not directly reflect our core operations. For instance, Adjusted EBITDA generally excludes interest expense, taxes and depreciation and amortization, each of which can vary substantially from company to company depending upon accounting methods and the book value and age of assets, capital structure, capital inv

Explanatory Note

This Current Report on Form 8-K/A amends the Current Report on Form 8-K filed with the Securities and Exchange Commission on October 30, 2024 (the “Original Form 8-K”). Following the submission of the Original Form 8-K, the Company discovered that an incorrect item number was inadvertently tagged in the submission (Item 2.02 should have been tagged instead of Item 1.02). The Company is amending the Original Form 8-K for the sole purpose of correcting the item tag. No disclosure has changed from the Original Form 8-K.

Item 2.02.  Results of Operations and Financial Condition

Disclosure of Non-GAAP Financial Measures

In the press release attached, the Company uses the terms “Adjusted EBITDA,” “free cash flow,” "net debt" and "net income before special items," which are not measures of financial performance under U.S. generally accepted accounting principles (“GAAP”). Also, in the tables to the press release, the non-GAAP financial measures "Segment and Total Company Income (Loss) before Special Items” (which includes operating income (loss) before special items) are presented and reconciled to financial measures under GAAP within the table "Segment and Total Company Income (Loss) from Operations (GAAP) to Income (Loss) from Operations before Special Items (Non-GAAP)." The non-GAAP financial measure "Diluted EPS excluding Special Items," is presented and reconciled to the financial measure under GAAP within the table "Net Income (Loss) (GAAP) and Diluted EPS (GAAP) to Net Income Excluding Special Items (non-GAAP) and Diluted EPS Excluding Special Items (Non-GAAP)." Information about these non-GAAP financial measures are included in the press release.

Our management uses and provides these non-GAAP financial measures as a measure of operating performance and liquidity to assist in comparing performance from period to period on a consistent basis, as a measure for planning and forecasting overall expectations for the Company and for evaluating actual results against such expectations. Adjusted EBITDA and free cash flow are also performance evaluation metrics used to determine incentive compensation for the Company's executive officers.

We believe that investors and other users of the financial statements benefit from the presentation of these non-GAAP financial measures because they provide additional metrics to compare the Company's operating performance and liquidity on a consistent basis and measure underlying trends and results of the Company's business. Adjusted EBITDA and operating income before special items assist in evaluating our oper

Adjusted EBITDA and operating income before special items assist in evaluating our operating performance because they remove the impact of certain items that management believes do not directly reflect our core operations. For instance, Adjusted EBITDA generally excludes interest expense, taxes and depreciation and amortization, each of which can vary substantially from company to company depending upon accounting methods and the book value and age of assets, capital structure, capital investment cycles and the method by which assets were acquired. It also eliminates stock-based compensation, which is a non-cash expense and

Also, in the tables to the press release, the non-GAAP financial measures "Segment and Total Company Income before Special Items” (which includes operating income before special items) and are presented and reconciled to financial measures under GAAP within the table "Segment and Total Company Income (Loss) from Operations (GAAP) to Income (Loss) from Operations before Special Items (Non-GAAP)" and the non-GAAP financial measure "Diluted EPS excluding Special Items", are presented and reconciled to financial measure under GAAP within the table "Net Loss (GAAP) and Diluted EPS (GAAP) to Net Loss Excluding Special Items (non-GAAP) and Diluted EPS Excluding Special Items (non-GAAP)". Information about these non-GAAP measures are included in the press release.

Our management uses these non-GAAP measurements as a measure of operating performance and liquidity to assist in comparing performance from period to period on a consistent basis, as a measure for planning and forecasting overall expectations and for evaluating actual results against such expectations. Adjusted EBITDA and free cash flow are also performance evaluation metrics used to determine incentive compensation for executive officers.

We believe that investors and other users of the financial statements benefit from the presentation of these non-GAAP measurements because they provide additional metrics to compare the Company's operating performance and liquidity on a consistent basis and measure underlying trends and results of the Company's business. Adjusted EBITDA and operating income before special items assist in evaluating our operating performance because they remove the impact of certain items that management believes do not directly reflect our core operations. For instance, Adjusted EBITDA generally excludes interest expense, taxes and depreciation and amortization, each of which can vary substantially from company to company depending upon accounting methods and the book value and age of assets, capital structure, capital investment cycles and the method by which assets were acquired. It also eliminates stock-based compensation, which is a non-cash expense and is excluded by management when evaluating the underlying performance of our business operations.

Adjusted EBITDA and free cash flow are also performance evaluation metrics used to determine incentive compensation for executive officers.

We believe that investors and other users of the financial statements benefit from the presentation of these non-GAAP measurements because they provide additional metrics to compare the Company's operating performance and liquidity on a consistent basis and measure underlying trends and results of the Company's business. Adjusted EBITDA and Segment and Total Company Income before Special Items assist in evaluating our operating performance because they remove the impact of certain items that management believes do not directly reflect our core operations. For instance, Adjusted EBITDA generally excludes interest expense, taxes and depreciation and amortization, each of which can vary substantially from company to company depending upon accounting methods and the book value and age of assets, capital structure, capital investment cycles and the method by which assets were acquired. It also eliminates stock-based compensation, which is a non-cash expense and is excluded by management when evaluating the underlying performance of our business operations.

Our management uses free cash flow when evaluating the performance of our business operations. This measurement also takes into account cash used to purchase fixed assets needed for business operations which are not expensed. We believe this measurement provides an additional tool to compare cash generated by our operations on a consistent basis and measure underlying

Item 2.02.  Results of Operations and Financial Condition

On August 2, 2021, Mistras Group, Inc. (the “Company,” “we” or “us”) issued a press release announcing the financial results for our second quarter of 2021, which ended June 30, 2021. A copy of the press release is attached as Exhibit 99.1 to this report.

After the press release was issued, a minor error was noted in the table to the press release titled “Unaudited Reconciliation of Net Income (Loss) (GAAP) and Diluted EPS (GAAP) to Net Income (Loss) Excluding Special Items (non-GAAP) and Diluted EPS Excluding Special Items (non-GAAP).” The special items, net of tax, for the six months ended June 30, 2021 was incorrectly shown at $0.02 but was actually $0.06, and the Diluted EPS before special items (non-GAAP) was shown as $0.04 but was actually $0.08. Attached as Exhibit 99.2 is a corrected version of the table “Unaudited Reconciliation of Net Income (Loss) (GAAP) and Diluted EPS (GAAP) to Net Income (Loss) Excluding Special Items (non-GAAP) and Diluted EPS Excluding Special Items (non-GAAP).” All GAAP measurements presented in the press release and the tables attached are correct. We will post on our website the press release with the corrected table.

Disclosure of Non-GAAP Financial Measures

In the press release attached, the Company uses the terms “Adjusted EBITDA,” “free cash flow, and "net debt", which are not measures of financial performance under U.S. generally accepted accounting principles (“GAAP”). In the tables to the press release, these non-GAAP financial measures and the non-GAAP financial measures "Segment and Total Company Income before Special Items”, "Net Income (Loss) Excluding Special Items", and "Diluted EPS excluding Special Items", are presented and reconciled to financial measures under GAAP. Information about these non-GAAP measures are included in the press release.

Our management uses these non-GAAP measurements as a measure of operating performance and liquidity to assist in comparing performance from period to period on a consistent basis, as a measure for planning and forecasting overall expectations and for evaluating actual results against such expectations. Adjusted EBITDA and free cash flow are also performance evaluation metrics used to determine incentive compensation for executive officers.

We believe that investors and other users of the financial statements benefit from the presentation of these non-GAAP measurements because they provide additional metrics to compare the Company's operating performance and liquidity on a consistent basis and measure underlying trends and results of the Company's business.
