We may continue to experience increased costs associated with tariffs or trade barriers, including recent U.S. tariffs imposed or threatened to be imposed on China, Canada, Mexico and other countries and any retaliatory actions taken by such countries. We will continue to monitor market conditions and respond accordingly.

The Unaudited Condensed Consolidated Financial Statements contained in this report have been prepared in conformity with U.S. generally accepted accounting principles ("GAAP") and Securities and Exchange Commission ("SEC") guidance allowing for reduced disclosure for interim periods. In the opinion of management, the Unaudited Condensed Consolidated Financial Statements include all adjustments, which are of a normal recurring nature, necessary for a fair presentation of the results for the interim periods of the years ending December 31, 2025 and December 31, 2024.

Certain items included in these statements are based on management’s estimates. Actual results may differ from those estimates. The results of operations for any interim period are not necessarily indicative of the results expected for the year. The accompanying Unaudited Condensed Consolidated Financial Statements should be read in conjunction with the notes to the Audited Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2024 (the "2024 Annual Report").

The accompanying Unaudited Condensed Consolidated Financial Statements include the accounts of Mistras Group, Inc. as well as its wholly-owned subsidiaries, majority-owned subsidiaries and consolidated variable interest entities (VIE). For consolidated subsidiaries in which the Company’s ownership interest is less than 100%, the non-controlling interests are reported in stockholders’ equity in the accompanying Condensed Consolidated Balance Sheets. The non-controlling interests in net results, net of tax, is classified separately in the accompanying Unaudited Condensed Consolidated Statements of Income (Loss). All significant intercompany accounts and transactions have been eliminated in consolidation.

Certain amounts in prior periods have been reclassified to conform to the current year presentation. The impacts of the reclassifications are shown in the tables below. Any reclassifications not shown below did not have a material effect on the Company's financial condition or results of operations as previously reported.

Beginning on January 1, 2025, the Company changed the presentation of certain costs on its Unaudited Condensed Consolidated Statements of Income (Loss), which include costs incurred at the Company's operational labs as well as the costs for certain personnel that indirectly support the Company’s delivery of services. This voluntary change in classification of certain overhead and personnel costs, which were determined to be directly related to the Company’s delivery of services, resulted in a decrease in Selling, general and administrative expenses and an offsetting increase in Cost of revenue. The Company believes this presentation is preferable as it will provide greater transparency regarding its Cost of revenue and better align with how the business is managed.

This change in classification has been applied retrospectively to all periods presented and affects Selling, general and administrative expenses; Cost of revenue; and Gross profit on the Company's Unaudited Condensed Consolidated Statements of Income (Loss). This change in presentation had no impact to Revenue, Income (loss) from operations, Income (loss) before provision (benefit) for income taxes, Provision (benefit) for income taxes, Net income (loss), Earnings (loss) per common share, or other components of equity, net assets or cash flows. In addition, Selling, general and administrative expenses and Other Expenses information disclosed in Note 14 Segment Disclosure was updated for this change. The impacts of the update to the presentation of certain indirect costs on the Company’s Condensed Consolidated Financial Statements for the three and six month periods ended June 30, 2024 are reflected below under the "Effect of change" columns.

The Company’s significant accounting policies are disclosed in Note 1–Summary of Significant Accounting Policies and Practices in the 2024 Annual Report. On an ongoing basis, the Company evaluates its estimates and assumptions, including among other things, those related to revenue recognition, long-lived assets, goodwill and acquisitions. Since the date of the 2024 Annual Report, there have been no material changes to the Company’s significant accounting policies.

Income taxes are accounted for under the asset and liability method. We recognize deferred tax assets and liabilities at enacted income tax rates for the temporary differences between the financial reporting bases and the tax bases of our assets and liabilities. Any effects of changes in income tax rates or tax laws are included in the provision for income taxes in the period of enactment. Our net deferred tax assets primarily consist of net operating loss carry forwards, or NOLs. A valuation allowance is provided if it is more likely than not that some or all of a deferred income tax asset will not be realized. A current tax liability or asset is recognized for the estimated taxes payable or refundable on tax returns for the current and prior years.

We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution.

The Company’s effective income tax rate was approximately 25.4% and 15.5% for the three months ended June 30, 2025 and 2024, respectively. The Company’s effective income tax rate was approximately 71.4% and 14.9% for the six months ended June 30, 2025 and 2024, respectively.

The effective income tax rate for the three months ended June 30, 2025, was higher than the statutory rate primarily due to the impact of a favorable discrete item related to stock compensation. The effective income tax rate for the three months ended June 30, 2024, was lower than the statutory rate primarily due to the impact of a favorable discrete item related to stock compensation.

The effective income tax rate for the six months ended June 30, 2025, was higher than the statutory rate primarily due to the impact of a favorable discrete item related to stock compensation. The effective income tax rate for the six months ended June 30, 2024, was lower than the statutory rate primarily due to the reversal of valuation allowances.

In November 2023, the Financial Accounting Standards Board ("FASB") issued ASU 2023-07, Segment Reporting (Topic 280) to expand the disclosures about a public entity's reportable segments and address requests from investors for additional, more detailed information about a reportable segment's expenses. The new standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. We adopted the provisions of this ASU in the fourth quarter of 2024 and applied the provisions retrospectively to each period presented in the consolidated financial statements. Adoption of the new standard did not have a material impact on our condensed consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) to enhance the transparency and decision usefulness of income tax disclosures, primarily related to the rate reconciliation and income taxes paid disclosures. The new standard is effective for fiscal years beginning after December 15, 2024. We are currently evaluating the impacts this standard will have on our disclosures.

On November 4, 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures, to require disaggregation of certain expense captions into specified categories in disclosures within the notes of the financial statements. The standard is effective for fiscal years beginning after December 31, 2026 and early adoption is permitted. The guidance is required to be applied prospectively and amendments in the ASU may be applied prospectively or retrospectively. We are currently evaluating the impacts this standard will have on our disclosures.

On March 6, 2024, the SEC adopted the final rule under SEC Release No. 33-11275, The Enhancement and Standardization of Climate-Related Disclosures for Investors, which will require registrants to provide certain climate-related information in their registration statements and periodic reports. The required disclosures will include, but are not limited to, specific disclosures about climate-related risks and their actual or likely material impacts on the registrant’s business, strategy, and outlook; the governance of climate-related risks and relevant risk management processes; Scope 1 and 2 greenhouse gas (GHG) emissions, if material or included in announced emission targets; certain climate-related financial statement metrics and related disclosures in a note to the audited financial statements; and information about climate-related targets and goals. The rules are effective on a rolling basis for various fiscal years, beginning for the Company with annual reports for the year ending December 31, 2025. However, in response to various legal challenges, the SEC voluntarily stayed the rules on April 4, 2024, which may impact the ultimate effective date of the rules. We will continue to monitor any developments on these rules and expected timing for compliance.
