PRINCETON JUNCTION, N.J., Aug. 06, 2025 (GLOBE NEWSWIRE) -- MISTRAS Group, Inc. (NYSE:MG), a global leader in technology-enabled industrial asset integrity and testing solutions, reported financial results for its second quarter and six months ended June 30, 2025.

Second Quarter 2025 Key Figures*

Revenue of $185.4 million, a decrease of 2.3%, yet flat giving effect to the exclusion of voluntary Laboratory consolidations
Gross profit of $53.9 million, up 5.1% or $2.6 million from $51.3 million, primarily due to an improved business mix and operating efficiencies; Gross profit margin of 29.1% as compared to 27.1%, an expansion of 200 basis points
Selling, general, and administrative ("SG&A") expenses of $39.8 million, up 10.0% or $3.6 million from $36.2 million, primarily due to foreign exchange loss of $2.8 million
Net income of $3.0 million and Earnings Per Diluted Share of $0.10; Net Income Excluding Special Items (Non-GAAP) of $5.8 million and Diluted Earnings Per Share Excluding Special Items (Non-GAAP) of $0.19
All-time highest second quarter Adjusted EBITDA of $24.1 million, compared to $22.1 million, an increase of 8.9%; Adjusted EBITDA margin of 13.0% as compared to 11.7%, an expansion of 130 basis points

*All comparisons are consolidated and versus the equivalent prior year period, unless otherwise noted and give effect to the reclassification of certain overhead and personnel expenses in the unaudited condensed consolidated statements of income (loss) from SG&A to cost of revenue. Please see the reconciliations of non-GAAP financial measures to the most directly comparable GAAP measures and additional information about the non-GAAP financial measures set forth in tables attached to this press release.

Second Quarter and First Half 2025 Additional Detailed Highlights:

Second Quarter results reflect the reclassification of certain overhead and personnel expenses in the Unaudited Condensed Consolidated Statements of Income (Loss), from SG&A to cost of revenue, as the Company determined this reclassification provides greater transparency regarding the true cost of the Company's revenue, and aligns with how the Company's business is managed. These overhead and personnel expenses, which were determined to be directly related to the Company's delivery of services, are generally variable to revenue being recognized, and results in gross profit that fully encompasses all costs necessary to generate such revenue. The reclassification recorded within the financials was $4.8 million and $9.7 million for the three and six month periods ended June 30, 2024, respectively. The impact of the reclassification of these costs from SG&A to cost of revenue for full year 2024 was approximately $20.9 million. This reclassification of overhead and personnel expenses had no impact on Operating Income, Net Income or Adjusted EBITDA comparability.

The Company recorded $3.0 million of reorganization and other costs in the second quarter of 2025 related to the Company's continuing initiative to reduce and recalibrate overhead costs, in addition to incremental costs of other related actions.

Net income was $3.0 million in the second quarter, or $0.10 per diluted share, as compared to net income of $6.4 million, or $0.20 per diluted share in the prior year comparable period. Second quarter net income excluding special items (non-GAAP), was $5.8 million, or $0.19 per diluted share, as compared to net income excluding special items (non-GAAP) of $6.8 million, or $0.21 per diluted share, in the prior year comparable period.

In the first half of 2025, net cash used in operating activities was $3.5 million, a decrease from $5.1 million of net cash provided by operating activities in the prior year period, largely due to an increase in days sales outstanding and working capital timing. Specifically, in the second quarter of 2025, the Company had a buildup in unbilled accounts receivable and a delay in invoicing related to its conversion to a new enterprise resource planning (ERP) system effective as of April 1, 2025. Although unbilled and billed accounts receivable balances increased significantly during the period ended June 30, 2025 related to this ERP implementation, the Company expects a reduction in these balances over the remainder of the year.

Free cash flow (non-GAAP) was negative $16.2 million in the first half of 2025, compared to negative $6.9 million in the prior year comparable period, attributable to the same factors impacting the Company's operating cash flow. On a trailing twelve month basis, which better normalizes year-over-year differences, net cash provided by operating activities was $41.6 million and free cash flow was $17.8 million, despite the first half 2025 year-over-year lagging results, compared to the prior year period. The Company expects free cash flow to normalize in the coming quarters and remains committed to strong free cash flow generation over the second half of 2025.

The Company's gross debt was $189.4 million as of June 30, 2025, compared to $169.6 million as of December 31, 2024 and $171.9 million as of March 31, 2025. The increase in gross debt during the period was attributable to the impacts to cash flow described above. The Company's net debt, a non-GAAP financial measure, was $168.8 million as of June 30, 2025.

The Company's trailing 12-month total consolidated debt leverage ratio as defined in the Company's credit agreement was just under 2.75 to 1.0 as of June 30, 2025, which was up slightly from December 31, 2024, but still well within the total consolidated debt leverage ratio of 3.75 to 1.0 required under the credit agreement. The Company expects to end fiscal 2025 with a total consolidated debt leverage ratio below 2.50 to 1.0.

Natalia Shuman, President and Chief Executive Officer commented:

"I am very pleased to report our second quarter performance, which resulted in a record Adjusted EBITDA of $24.1 million, up 8.9% year-over-year, reflecting significant improvement in our operating leverage as a result of our strategic initiatives. As we re-tool, re-shape and re-invigorate our business, we have taken many decisive steps to enhance profitability and sharpen our focus. This reflects the strength of our operating model, disciplined cost management, and continued focus on driving efficiencies across the business. These second quarter results demonstrated our ability to deliver value despite market volatility, positioning us well to restart our growth engine. We have adjusted our Company's organizational structure, delayered the organization, reinforced performance management at each of our labs, and implemented clear key performance indicators (KPIs) which we are using to continuously manage and control our costs. These are not just short-term cost calibrations, they are structural improvements designed to improve and expand decision making capacity, reinforce operational organization and help ensure operating leverage through all business cycles."

Ms. Shuman continued, "As the market continues to evolve, we are focused on aligning our capabilities to meet increasing demand for more integrated, agile, and data-enabled solutions. By combining advanced technologies with deep operational expertise, we are positioning MISTRAS to lead in high-growth sectors and provide critical support where reliability, safety, and performance matter most."

2025 Outlook

The Company is not providing full year guidance for fiscal 2025, as the CEO and renewed senior management team are still reviewing the Company's entire portfolio of businesses. The Company is also continuously assessing market volatility, including the impact of changes in U.S. trade policies, the imposition of tariffs and related retaliatory tariffs, on its business and results for fiscal 2025. Nevertheless, the Company expects its 2025 Adjusted EBITDA to exceed the Adjusted EBITDA level in 2024, which had been the second highest annual level achieved all-time.

Certain statements contained in this press release are "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Such forward-looking statements include, but are not limited to, the impacts of foreign currency exchange risks, the impacts of our new ERP implementation, including the reduction and normalization of our accounts receivable balances, and recently announced tariffs and retaliatory tariffs and changes to U.S. trade policy on our business and financial results, and additional operational and strategic actions, such as the implementation of KPIs, that we have taken or expect or seek to take in furtherance of our strategies and activities to reduce overhead and related costs and enhance our financial results and future growth. Such forward-looking statements relate to MISTRAS' financial results and estimates, products and services, business model, operational and strategic initiatives to improve operating leverage, strategy, growth opportunities, profitability and competitive position, and other matters. These forward-looking statements generally use words such as "future," "possible," "potential," "targeted," "anticipate," "believe," "estimate," "expect," "intend," "plan," "predict," "project," "will," "may," "should," "could," "would" and other similar words and phrases. Such statements are not guarantees of future performance or results and will not necessarily be accurate indications of the times at, or by which, such performance or results will be achieved, if at all. These statements are subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in these statements. A list, description and discussion of these and other risks and uncertainties can be found in the "Risk Factors" section of the Company's Annual Report on Form 10-K for the year ended December 31, 2024 filed with the U.S. Securities and Exchange Commission on March 11, 2025, as updated by our reports on Form 10-Q and Form 8-K.

Use of Non-GAAP Financial Measures

In addition to financial information prepared in accordance with generally accepted accounting principles in the U.S. ("GAAP"), this press release also contains adjusted financial measures that are not prepared in accordance with GAAP and that we believe provide investors and management with supplemental information relating to the Company's operating performance and trends that facilitate comparisons between periods and with respect to trends and projected information. The term "Adjusted EBITDA" used in this release is a financial measure not calculated in accordance with GAAP and is defined by the Company as net income attributable to MISTRAS Group, Inc. plus: interest expense, provision for income taxes, depreciation and amortization, share-based compensation expense, certain acquisition related costs (including transaction due diligence costs and adjustments to the fair value of contingent consideration), foreign exchange (gain) loss, non-cash impairment charges, reorganization and other costs and, if applicable, certain additional special items which are noted. A reconciliation of Adjusted EBITDA to Net Income (Loss) as computed under GAAP is set forth in a table attached to this press release. The Company also uses the terms "free cash flow" and "trailing twelve months free cash flow," non-GAAP financial measures. The Company defines "free cash flow" as cash provided by operating activities less capital expenditures (which is classified as an investing activity). For the term "trailing twelve months free cash flow," the Company aggregates cash provided by operating activities for the trailing twelve-month period ended June 30, 2025 and subtracts aggregated capital expenditures over the same trailing twelve month period. The Company additionally uses the terms:

"Segment and Total Company Income (Loss) from Operations (GAAP) to Income (Loss) from Operations before Special Items (non-GAAP)", "Net Income (Loss) (GAAP) and Diluted EPS (GAAP) to Net Income Excluding Special Items (non-GAAP) and Diluted EPS Excluding Special Items (non-GAAP)" which reconciles the non-GAAP amounts to the GAAP financial measure. The non-GAAP financial performance measure "Income (loss) from operations before special items" is used for each of our three operating segments, the Corporate segment and the "Total Company". Income (Loss) from operations before Special Items excludes: (a) transaction expenses related to acquisitions, such as professional fees and due diligence costs, (b) the net changes in the fair value of acquisition-related contingent consideration liabilities, (c) impairment charges, (d) reorganization and other costs, which includes items such as severance, labor relations matters and asset and lease termination costs and (e) other special items. These adjustments have been excluded from the GAAP measure because these expenses and credits are not related to our or any individual segment's core business operations. The acquisition related costs and special items can be a net expense or credit in any given period. This press release also includes the term "net debt", a non-GAAP financial measure which the Company defines as the sum of the current and long-term portions of long-term debt, less cash and cash equivalents. Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP measures are also set forth in tables attached to this press release. Each of these non-GAAP financial measures has material limitations as a performance or liquidity measure and should not be considered alternatives to Net Income (Loss) or any other measures derived in accordance with GAAP. Because Income (loss) from operations before special items and other non-GAAP financial measures used in this press release may not be calculated in the same manner by all companies, these measures may not be comparable to other similarly titled measures used by other companies.
