1. Description of Business and Basis of Presentation
Description of Business
Mistras Group, Inc., together with its subsidiaries (the "Company"), is a leading “one source” multinational provider of integrated technology-enabled asset protection solutions helping to maximize the safety and operational uptime for civilization’s most critical industrial and civil assets.
Backed by an innovative, data-driven asset protection portfolio, proprietary technologies, and decades-long legacy of industry leadership, the Company helps clients with asset-intensive infrastructure in the oil and gas, aerospace and defense, industrials, power generation and transmission (including alternative and renewable energy), other process industries and infrastructure, research and engineering and other industries towards achieving and maintaining operational excellence. By supporting these organizations that help fuel our vehicles and power our society; inspecting components that are trusted for commercial, defense, and space craft; and building real-time monitoring systems to help avoid catastrophic incidents, the Company helps the world at large.
The Company enhances value for its clients by integrating asset protection throughout supply chains and centralizing integrity data through a suite of Industrial Internet of Things ("IoT")-connected digital software and monitoring solutions, including OneSuite™, which serves as an ecosystem platform, pulling together all of the Company’s software and data services capabilities, for the benefit of its customers.
The Company’s core capabilities also include non-destructive testing (“NDT”) field inspections enhanced by advanced robotics, laboratory quality control, laboratory materials services, shop laboratory assurance testing, sensing technologies and NDT equipment, asset and mechanical integrity engineering services, and light mechanical maintenance and access services.
The Company has three operating segments. Our segments are as follows:
•North America This segment provides asset protection solutions predominantly in North America, with the largest concentration in the United States, followed by Canada, consisting primarily of NDT, inspection, mechanical and engineering services that are used to evaluate the safety, structural integrity and reliability of critical energy, industrial and public infrastructure and commercial aerospace components. Software, digital and data services are included in this segment.
•International. This segment offers services, products and systems similar to those of the other segments to select markets within Europe, the Middle East, Africa, Asia and South America, but not to customers in China and South Korea, which are served by the Products and Systems segment.
•Products and Systems. This segment designs, manufactures, sells, installs and services the Company’s asset protection products and systems, including equipment and instrumentation, predominantly in the United States.
Recent Developments
Overall, the Company has taken actions to help ensure the health and safety of Company employees and those of its customers and suppliers; maintain business continuity and financial strength and stability; and serve customers as they provide essential products and services to the world.
The Russian-Ukrainian war and the conflict in the Middle East between Israel and Hamas continues to create disruptions in the oil and gas market and the supply chain in general, which is resulting in some disruption to our business operations. The Company's European operations are currently experiencing increased costs associated with higher energy costs, among others, due in part to the Russian-Ukrainian war.

The Company is currently unable to predict with certainty the overall impact that the factors discussed above and the effect of inflationary pressures may have on its business, results of operations or liquidity or in other ways which the Company cannot yet determine. The Company will continue to monitor market conditions and respond accordingly.
Basis of Presentation
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 statement of the results for the interim periods of the years ending December 31, 2024 and December 31, 2023.
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 2023 Annual Report on Form 10-K ("2023 Annual Report").
Principles of Consolidation
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 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. The results of operations of companies acquired are included from the date of acquisition.
Reclassification
Certain amounts in prior periods have been reclassified to conform to the current year presentation. Such reclassifications did not have a material effect on the Company’s financial condition or results of operations as previously reported.
Significant Accounting Policies
The Company’s significant accounting policies are disclosed in Note 1–Summary of Significant Accounting Policies and Practices in the 2023 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 2023 Annual Report, there have been no material changes to the Company’s significant accounting policies.

Income Taxes
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 carryforwards, 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.
As of June 30, 2024, management concluded that it is more likely than not that a substantial portion of the Company’s deferred tax assets will be realized.
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 15.5% and (974.3)% for the three months ended June 30, 2024 and 2023, respectively. The Company’s effective income tax rate was approximately 14.9% and 21.5% for the six months ended June 30, 2024 and 2023, respectively.
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 reversal of a valuation allowance which was a favorable discrete item in the period. The effective income tax rate for the six months ended June 30, 2023 was higher than the statutory rate due primarily to a $0.7 million valuation allowance recorded during the period related to a foreign jurisdiction.
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. The effective income tax rate for the six months ended June 30, 2023 was lower than the statutory rate due primarily to an unfavorable discrete item related to stock compensation.
Recent Accounting Pronouncements
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 are currently evaluating the impact of ASU 2023-07 on our 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 impact of ASU 2023-09 on our financial statements.
2. Revenue
The Company derives the majority of its revenue by providing services on a time and material basis, and are short-term in nature. The Company accounts for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers.

Notes to Unaudited Condensed Consolidated Financial Statements
(tabular dollars and shares in thousands, except per share data)
Performance Obligations
The Company provides highly integrated and bundled inspection services to its customers. The majority of the Company’s contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and is, therefore, not distinct. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation using the Company’s best estimate of the standalone selling price of each distinct good or service in the contract. The primary method used to estimate standalone selling price is a relative selling price based on price lists.
Contract modifications are not routine in the performance of the Company’s contracts. Generally, when contracts are modified, the modification is to account for changes in scope to the goods and services that are provided. In most instances, contract modifications are for goods or services that are distinct, and, therefore, are accounted for as a separate contract.
The Company’s performance obligations are satisfied over time as work progresses or at a point in time. The majority of the Company’s revenue is recognized over time as work progresses for the Company’s service deliverables, which includes providing testing, inspection and mechanical services to our customers. Revenue is recognized over time, based on time and material incurred to date which best portrays the transfer of control to the customer. The Company also utilizes an available practical expedient that provides for revenue to be recognized in an amount that corresponds directly with the value to the customer of the entity’s performance completed to date. Fixed fee arrangements are determined based on expected labor, material, and overhead to be consumed on fulfillment of such services. For these arrangements, revenue is recognized on a cost-to-cost method tracked on an input basis.
The majority of our revenue recognized at a point in time is related to product sales when the customer obtains control of the asset, which is generally upon shipment to the customer. Contract costs include labor, material and overhead.
The Company expects any significant remaining performance obligations to be satisfied within one year.
Contract Estimates
The majority of the Company's revenues are short-term in nature. The Company enters into master service agreements ("MSA"s) with customers that specify an overall framework and contract terms. The actual contracting to provide services or furnish products are triggered by a work order, purchase order, or some similar document issued pursuant to a MSA which sets forth the scope of services and/or identifies the products to be provided. From time-to-time, the Company may enter into longer-term contracts, which can range from several months to several years. Revenue on certain contracts is recognized as work is performed based on total costs incurred to date in relation to the total estimated costs for the performance of the contract at completion. This includes contract estimates of costs to be incurred for the performance of the contract. Cost estimation is based upon the professional knowledge and experience of the Company's project managers, engineers and financial professionals. Factors that are considered in estimating the work to be completed include the availability of materials, the effect of any delays in the Company's project performance and the recoverability of any claims. Whenever revisions of estimates, contract costs and/or contract values indicate that the contract costs will exceed estimated revenues, thus creating a loss, a provision for the total estimated loss is recorded in that period.

Contract Balances
The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities) on the Consolidated Balance Sheets. Amounts are generally billed as work progresses in accordance with agreed-upon contractual terms, generally at periodic intervals (e.g., weekly, bi-weekly or monthly). Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. However, the Company sometimes receives advances or deposits from its customers before revenue is recognized, resulting in contract liabilities. These assets and liabilities are aggregated on an individual contract basis and reported on the Consolidated Balance Sheets at the end of each reporting period within accounts receivable, net or accrued expenses and other current liabilities.
Revenue recognized during the six months ended June 30, 2024 and 2023 that was included in the contract liability balance at the beginning of such year was $4.8 million and $4.6 million, respectively, for each period. Changes in the contract asset and liability balances during these periods were not materially impacted by any other factors. The Company applies the practical expedient to expense incremental costs incurred related to obtaining a contract when the amortization period of the asset that the Company otherwise would have recognized is one year or less.
3. Share-Based Compensation
The Company grants share-based incentive awards to its eligible employees and non-employee directors under its 2016 Long-Term Incentive Plan (the "2016 Plan"). Awards granted under the 2016 Plan may be in the form of stock options, restricted stock units and other forms of share-based incentives, including performance-based restricted stock units, stock appreciation rights and deferred stock rights. At the annual shareholders meeting on May 14, 2024, the Company’s shareholders approved an amendment to the 2016 Plan, including an increase to the total number of shares that may be issued under the 2016 Plan by 1.3 million, for a total of 6.2 million shares that are authorized for issuance under the 2016 Plan, of which approximately 1,600,000 shares were available for future grants as of June 30, 2024.
Stock Options

(tabular dollars and shares in thousands, except per share data)
On October 11, 2023, Mr. Stamatakis was granted an award of stock options to purchase 250,000 shares of common stock of the Company, with an exercise price of $5.36, the closing price of the Company's common stock as quoted on the New York Stock Exchange on the grant date (the "Options"). The Options were granted as an inducement for Mr. Stamatakis to accept the position of Interim President and CEO of the Company and were therefore granted outside the 2016 Plan, as permitted by the rules of the NYSE. The Options can be exercised any time after the grant date until its expiration date, which is the earlier of 10 years from the grant date or one year following the date Mr. Stamatakis is no longer serving as an officer, director or in any other capacity of the Company.
The following table sets forth a summary of the stock option activity, weighted-average exercise prices and options outstanding as of June 30, 2024 as follows (in thousands, except per share amounts and years):

Restricted Stock Unit Awards
For the three months ended June 30, 2024 and June 30, 2023, the Company recognized share-based compensation expense related to restricted stock unit awards of $1.3 million and $0.8 million, respectively. For the six months ended June 30, 2024 and 2023, the Company recognized share-based compensation expense related to restricted stock unit awards of $2.3 million and $1.8 million, respectively. As of June 30, 2024, there was $10.7 million of unrecognized compensation costs, net of estimated forfeitures, related to restricted stock unit awards, which is expected to be recognized over a remaining weighted-average period of 2.6 years. Upon vesting, restricted stock units are generally net share-settled to cover the required withholding tax and the remaining amount is converted into an equivalent number of shares of common stock.

Performance Restricted Stock Units
The Company maintains Performance Restricted Stock Units ("PRSUs") that have been granted to select executives and senior officers whose ultimate payout may vary between zero and 200% of the target award, based on the Company’s performance over a one-year period based on specific metrics approved by the Compensation Committee of the Board of Directors of the Company.
For 2023, the Compensation Committee used the following three performance metrics for PRSUs approved in that year.
1.Free Cash Flow defined as net cash provided by operating activities less purchases of property, plant, equipment and intangible assets and is subject to adjustments approved by the Compensation Committee.
2.Adjusted EBITDA defined as net income attributable to the Company plus: interest expense, provision for income taxes, depreciation and amortization, share-based compensation expense and certain acquisition related costs (including transaction due diligence costs and adjustments to the fair value of contingent consideration), foreign exchange (gain) loss and, if applicable, certain special items which are noted.
3.Revenue
For PRSUs awarded in 2024, the Compensation Committee utilized the same metrics as 2023 PRSUs, but with revised performance goals.
PRSUs are equity-classified and compensation costs related to PRSUs with performance conditions are initially measured using the fair value of the underlying stock at the date of grant. Compensation costs related to the PRSUs with performance conditions are subsequently adjusted for changes in the expected outcomes of the performance conditions. Compensation cost related to the PRSUs with a market condition is not reversed if the market condition is not achieved, provided the employee requisite service has been rendered. Earned PRSUs generally vest ratably in four equal annual installments over the four years following completion of the performance period, for a total requisite service period of up to five years, and have no dividend rights.

Performance condition adjustments during the six months ended June 30, 2023 were attributable to the Compensation Committee's final calculation of the award metrics for calendar year 2022. As a result, the calendar year 2022 PRSUs decreased by approximately 215,000 units during the six months ended June 30, 2023.
For the three months ended June 30, 2024 and June 30, 2023, the Company recognized aggregate share-based compensation expense related to the awards described above of approximately $0.3 million and $0.2 million, respectively. For the six months ended June 30, 2024 and June 30, 2023, the Company recognized aggregate share-based compensation expense related to the awards described above of approximately $0.3 million and $0.6 million, respectively. At June 30, 2024, there was $2.5 million of total unrecognized compensation costs related to approximately 355,000 non-vested PRSUs, which is expected to be recognized over a remaining weighted-average period of 2.8 years.
4. Earnings (loss) per Share
Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares outstanding during the period. Diluted earnings per share is computed by dividing net income (loss) by the sum of (1) the weighted-average number of shares of common stock outstanding during the period, and (2) the dilutive effect of assumed conversion of equity awards using the treasury stock method. With respect to the number of weighted-average shares outstanding (denominator), diluted shares reflects: (i) the exercise of options to acquire common stock to the extent that the options’ exercise prices are less than the average market price of common shares during the period and (ii) the pro forma vesting of restricted stock units.

9. Goodwill
Changes in the carrying amount of goodwill by segment is shown below:

Balance at June 30, 2024 | $ | 184,988 |  |  | $ | — |  |  | $ | — |  |  | $ | 184,988 |

The Company reviews goodwill for impairment on a reporting unit basis on October 1 of each year and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable.
During the third quarter of 2023, a triggering event was identified within the Company's reporting units within the International segment due to decreased gross margin in the current period as a result of inflationary pressures and rising energy costs impacting the International reporting units' operations. As a result, the Company performed an interim quantitative goodwill impairment test.
In performing the interim quantitative goodwill impairment test and consistent with prior practice, the Company determined the fair value of each of the reporting units using a combination of the income approach and the market approach by assessing each of these valuation methodologies based upon availability and relevance of comparable company data and determining the appropriate weighting.
Under the income approach, the fair value for each of the reporting units was determined based on the present value of estimated future cash flows, discounted at an appropriate risk-adjusted rate. The Company used internal forecasts, updated for recent events, to estimate future cash flows using a terminal value calculation, which incorporates historical and forecasted trends, including an estimate of long-term future growth rates, based on the Company’s most recent views of the long-term outlook for each reporting unit. The Company's internal forecasts include assumptions about future profitability, including the expected demand for the Company’s goods and services. Due to the inherent uncertainties involved in making estimates and assumptions, actual results may differ from those assumed in the forecasts. The Company derived the discount rates using a capital asset pricing model and analyzing published rates for industries relevant to the reporting units to estimate the cost of equity financing. The Company used discount rates that are commensurate with the risks and uncertainties inherent in the respective businesses and in the Company's internally developed forecasts and which are updated for recent events. Increased interest rates in the current period increased the discount rate associated with the reporting units which contributed to an unfavorable decrease in the reporting units value.
The market approach valuation was derived from metrics of publicly traded companies or historically completed transactions of comparable businesses. The selection of comparable businesses was based on the markets in which the reporting units operate, considering risk profiles, size, geography, and diversity of products and services.
Based upon the results of the interim quantitative goodwill impairment test, the Company recorded an impairment charge of $13.8 million within the International reporting units. The impairment was calculated based on the difference between the estimated fair value and the carrying value of the reporting units. Any significant adverse changes in future periods to the Company’s internal forecasts or the external market conditions, if any, could reasonably be expected to negatively affect its key assumptions and may result in future goodwill impairment charges which could be material.
The Company performed a quantitative annual impairment test as of October 1, 2023 and the Company did not identify any changes in circumstances that would indicate the carrying value of goodwill may not be recoverable. Additionally, through June 30, 2024, the Company did not identify any changes in circumstances that would indicate the carrying value of goodwill may not be recoverable. Significant adverse changes in future periods could negatively affect the Company's key assumptions and may result in future goodwill impairment charges which could be material.

Long-term debt, net of current portion | $ | 189,692 |  |  | $ | 181,499 |

Senior Credit Facility
On August 1, 2022, the Company entered into a new credit agreement (the “Credit Agreement”) which provides the Company with a $190 million 5-year committed revolving credit facility and a $125 million term loan with a balance of $113.7 million as of June 30, 2024. The Credit Agreement permits the Company to borrow up to $100 million in non-U.S. dollar currencies and to use up to $20 million of the credit limit for the issuance of letters of credit. Both the revolving line of credit and the term loan under the Credit Agreement have a maturity date of July 30, 2027.
The Credit Agreement has the following key terms, conditions and financial covenants:
•Borrowings bear interest at Secured Overnight Financing Rate ("SOFR") plus a credit spread adjustment and applicable SOFR margin ranging from 1.25% to 2.75%, based upon our Total Consolidated Debt Leverage Ratio (defined below); under the Prior Credit Agreement, the margin was based upon the LIBOR margin.
◦Total Consolidated Debt Leverage Ratio means the ratio of (a) Total Consolidated Debt to (b) EBITDA (as defined in the Credit Agreement) for the trailing four consecutive fiscal quarters.
◦Total Consolidated Debt means all indebtedness (including subordinated debt) of the Company on a consolidated basis.
•The Company has the benefit of the lowest SOFR margin if its Total Consolidated Debt Leverage Ratio is equal to or less than 1.25 to 1.0, and the margin increases as the ratio increases, to the maximum margin if the ratio is greater than 3.75 to 1.0. The Credit Agreement is secured by liens on substantially all the assets of the Company and certain of its U.S. subsidiaries and is guaranteed by those U.S. subsidiaries.
•The Company has to maintain a Total Consolidated Debt Leverage Ratio of no more than 4.0 to 1.0 at the end of each quarter through June 30, 2023 and stepping down to a maximum permitted ratio of no more than 3.75 to 1.0 for the remainder of the term.
•The Company has to maintain a Fixed Charge Coverage Ratio of 1.25 to 1.0 for the duration of the Credit Agreement, as defined in the Credit Agreement.
•The Credit Agreement limits the Company’s ability to, among other things, create liens, make investments, incur more indebtedness, merge or consolidate, make dispositions of property, pay dividends, make distributions to stockholders or repurchase our stock, enter into a new line of business, enter into transactions with affiliates and enter into burdensome agreements.
•The Credit Agreement does not limit the Company’s ability to acquire other businesses or companies except that the acquired business or company must be in the Company's line of business, the Company must be in compliance with the financial covenants on a pro forma basis after taking into account the acquisition, and the Company must provide written notice at least five business days prior to the date of an acquisition of $10 million or more.

(tabular dollars and shares in thousands, except per share data)
•Quarterly payments on the term loan of $1.56 million through June 30, 2024, then increasing to $2.34 million through June 30, 2025, and to $3.12 million for each quarterly payment thereafter through maturity.
As of June 30, 2024, the Company had borrowings of $196.6 million and a total of $3.2 million of letters of credit outstanding under the Credit Agreement. The Company has capitalized costs associated with debt modifications of $1.0 million as of June 30, 2024, which is included in Other assets on the Condensed Consolidated Balance Sheets and will be amortized into interest expense over the remaining term of the Credit Agreement through July 30, 2027.
As of June 30, 2024, the Company was in compliance with the terms of the Credit Agreement. The Company continuously monitors compliance with the covenants contained in its Credit Agreement. The Company believes that it is probable that the Company will be able to comply with the financial covenants in the Credit Agreement and that sufficient credit remains available under the Credit Agreement to meet the Company's liquidity needs. However, such matters cannot be predicted with certainty.
Other debt
The Company’s other debt includes bank financing provided at the local subsidiary level used to support working capital requirements and fund capital expenditures. At June 30, 2024, there was an aggregate of approximately $3.1 million outstanding, payable at various times through 2030. Monthly payments range from $1.0 thousand to $15.0 thousand and interest rates range from 0.4% to 3.5%.
13. Fair Value Measurements
The Company performs fair value measurements in accordance with the guidance provided by ASC 820, Fair Value Measurements and Disclosures. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. It also establishes a three level hierarchy that prioritizes the inputs used to measure fair value.
Financial instruments measured at fair value on a recurring basis
The fair value of contingent consideration liabilities was estimated using a discounted cash flow technique with significant inputs that are not observable in the market and thus represents a Level 3 fair value measurement as defined in ASC 820. The significant inputs in the Level 3 measurement not supported by market activity include the probability assessments of expected future cash flows related to the acquisitions, appropriately discounted considering the uncertainties associated with the obligation, and as calculated in accordance with the terms of the applicable acquisition agreements.
The following table represents the changes in the fair value of Level 3 contingent consideration:

|  | Six months ended June 30,
|  | 2024 |  | 2023
Beginning balance |  | $ | — |  |  | $ | 938 |
Payments |  | — |  |  | (938) |
Revaluation |  | — |  |  | — |
Ending balance |  | $ | — |  |  | $ | — |

Financial instruments not measured at fair value on a recurring basis
The Company has evaluated current market conditions and borrower credit quality and has determined that the carrying value of its long-term debt approximates fair value. The fair value of the Company’s notes payable and finance lease obligations approximates their carrying amounts based on anticipated interest rates which management believes would currently be available to the Company for similar issuances of debt.

14. Commitments and Contingencies
Legal Proceedings and Government Investigations
The Company is periodically involved in lawsuits, investigations and claims that arise in the ordinary course of business. While the Company cannot predict with certainty the ultimate resolution of lawsuits, investigations and claims asserted against it, the Company does not believe that any currently pending or threatened legal proceeding to which the Company is or is likely to become a party will have a material adverse effect on its business, results of operations, cash flows or financial condition. The costs incurred by the Company to defend lawsuits, investigations and claims and amounts the Company pays to other parties because of these matters may be covered by insurance in some circumstances.
Litigation and Commercial Claims
The Company and a subsidiary of the Company, Mistras Arizona Inspection Services LLC (“Mistras Arizona”), are subject to a lawsuit filed by the Arizona Department of Environmental Quality (“DEQ”). The lawsuit, captioned State of Arizona v. Mistras Group, Inc., Mistras Arizona Inspection Services, LLC and Naiman Phoenix, Ltd., was originally filed on February 27, 2024, in the Superior Court of the State of Arizona for Maricopa County, CV 2024-003866. The Complaint alleges various violations of the Arizona environmental laws and regulations in connection with the operation of the Mistras Arizona testing facility in Phoenix, Arizona. The complaint seeks injunctive relief, the closing of a chromic acid plating line and air scrubber, implementation of a site assessment plan approved by the DEQ, corrective and remedial action to bring the facility in compliance, and costs and penalties. Mistras Arizona and the Company have also received notice of violations from the DEQ for alleged violations of Arizona environmental laws and regulations and from the Maricopa County Department of Air Quality for alleged violations of various regulations regarding air quality. This matter is in the early stages but it is probable that remediation costs will be incurred, and it is possible fines and penalties may be imposed related to this lawsuit, but the Company is unable to assess the range of loss the Company, or Mistras Arizona may incur.
In addition, Mistras Arizona’s operations in Phoenix are located within a leased site within the footprint of the Motorola 52nd Street Superfund Site (the “Motorola Site”). Mistras Arizona received a General Notice Letter from the US Environmental Protection Agency (the "EPA"), dated May 21, 2024, informing Mistras Arizona that the EPA has identified it as a potentially responsible party in relation to the Motorola Site.
Pension Related Contingencies
Certain of the Company’s subsidiaries had significant reductions in their unionized workers in 2018. The collective bargaining agreements for the employees of these subsidiaries required contributions for these employees to two national multi-employer pension funds. The reduction in employees resulted in one of the Company's subsidiaries incurring a complete withdrawal to one of the pension funds under the Employee Retirement Income Security Act of 1974 ("ERISA"), which was fully satisfied in 2019. The Company has determined that the subsidiary is likely to incur partial or complete withdrawal liability to the other pension fund. The balance of the estimated total amount of this potential liability as of June 30, 2024 is approximately $2.5 million, which were incurred in 2018 and 2019.
15. Segment Disclosure
The Company’s three operating segments are:
•North America. This segment provides asset protection solutions predominantly in North America, with the largest concentration in the United States, followed by Canada, consisting primarily of NDT, inspection, mechanical and engineering services that are used to evaluate the safety, structural integrity and reliability of critical energy, industrial and public infrastructure and commercial aerospace components. Software, digital and data services are included in this segment.

Table of Contents
Mistras Group, Inc. and Subsidiaries
Notes to Unaudited Condensed Consolidated Financial Statements
(tabular dollars and shares in thousands, except per share data)
•International. This segment offers services, products and systems similar to those of the other segments to select markets within Europe, the Middle East, Africa, Asia and South America, but not to customers in China and South Korea, which are served by the Products and Systems segment.
•Products and Systems. This segment designs, manufactures, sells, installs and services the Company’s asset protection products and systems, including equipment and instrumentation, predominantly in the United States.
Costs incurred for general corporate services, including finance, legal, and certain other costs that are provided to the segments are reported within Corporate and eliminations. Sales to the International segment from the Products and Systems segment and subsequent sales by the International segment of the same items are recorded and reflected in the operating performance of both segments. Additionally, engineering charges and royalty fees charged to the North America and International segments by the Products and Systems segment are reflected in the operating performance of each segment.
The accounting policies of the reportable segments are the same as those described in Note 1-Description of Business and Basis of Presentation. Segment income from operations is one of the primary performance measures used by the chief operating decision maker, to assess the performance of each segment and make resource allocation decisions. Certain general and administrative costs such as human resources, information technology and training are allocated to the segments. Segment income from operations excludes interest and other financial charges and income taxes. Corporate and other assets are comprised principally of cash, deposits, property, plant and equipment, domestic deferred taxes, deferred charges and other assets. Corporate loss from operations consists of administrative charges related to corporate personnel and other charges that cannot be readily identified for allocation to a particular segment.
Selected consolidated financial information by segment for the periods shown was as follows: (with intercompany transactions eliminated in Corporate and eliminations)

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following Management’s Discussion and Analysis (“MD&A”) provides a discussion of our results of operations and financial position for the three and six months ended June 30, 2024 and 2023. The MD&A should be read together with our Unaudited Condensed Consolidated Financial Statements and related notes included in Item 1 in this Quarterly Report on Form 10-Q (the "Quarterly Report") and our audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2023, (“2023 Annual Report”). Unless otherwise specified or the context otherwise requires, “Mistras,” “the Company,” “we,” “us” and “our” refer to Mistras Group, Inc. and its consolidated subsidiaries. The MD&A includes the following sections:
•Forward-Looking Statements
•Overview
•Note about Non-GAAP Measures
•Consolidated Results of Operations
•Liquidity and Capital Resources
•Critical Accounting Policies and Estimates
Forward-Looking Statements
This Quarterly Report contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, and Section 21E of the Securities Exchange Act of 1934 (“Exchange Act”). Such forward-looking statements include those that express plans, anticipation, intent, contingency, goals, targets or future development and/or otherwise are not statements of historical fact. These forward-looking statements are based on our current expectations and projections about future events and they are subject to risks and uncertainties known and unknown that could cause actual results and developments to differ materially from those expressed or implied in such statements.
In some cases, you can identify forward-looking statements by terminology, such as “goals,” or “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “may,” “could,” “should,” “would,” “predicts,” “appears,” “projects,” or the negative of such terms or other similar expressions. You are urged not to place undue reliance on any such forward-looking statements, any of which may turn out to be wrong due to inaccurate assumptions, various risks, uncertainties or other factors known and unknown. Factors that could cause or contribute to differences in results and outcomes from those in our forward-looking statements include, without limitation, those discussed in the “Business—Forward-Looking Statements,” and “Risk Factors” sections of our 2023 Annual Report as well as those discussed in this Quarterly Report and in our other filings with the SEC. In addition, there are various developments discussed below which could create risks and uncertainty about our business, results of operations or liquidity.
Overview
We are a leading "one source" multinational provider of integrated technology-enabled asset protection solutions, helping to maximize the safety and operational uptime for civilization’s most critical industrial and civil assets.
Backed by an innovative, data-driven asset protection portfolio, proprietary technologies, and decades-long legacy of industry leadership, the Company helps clients with asset-intensive infrastructure in the oil and gas, aerospace and defense, industrials, power generation and transmission (including alternative and renewable energy), other process industries and infrastructure, research and engineering and other industries towards achieving and maintaining operational excellence. By supporting these organizations that help fuel our vehicles and power our society; inspecting components that are trusted for commercial, defense, and space craft; and building real-time monitoring systems to help avoid catastrophic incidents, the Company helps the world at large.
The Company enhances value for its clients by integrating asset protection throughout supply chains and centralizing integrity data through a suite of Industrial Internet of Things ("IoT")-connected digital software and monitoring solutions, including

OneSuite™, which serves as an ecosystem platform, pulling together all of the Company’s software and data services capabilities, for the benefit of its customers.
The Company’s core capabilities also include non-destructive testing (“NDT”) field inspections enhanced by advanced robotics, laboratory quality control and assurance testing, sensing technologies and NDT equipment, asset and mechanical integrity engineering services, and light mechanical maintenance and access services.
Our operations consist of three reportable segments: North America, International, and Products and Systems.
•North America provides asset protection solutions predominantly in North America, with the largest concentration in the United States, followed by Canada, consisting primarily of NDT, inspection, mechanical and engineering services that are used to evaluate the structural integrity and reliability of critical energy, industrial and public infrastructure and commercial aerospace components. Software, digital and data services are included in this segment.
•International offers services, products and systems similar to those of the other segments to select markets within Europe, the Middle East, Africa, Asia and South America, but not to customers in China and South Korea, which are served by the Products and Systems segment.
•Products and Systems designs, manufactures, sells, installs and services the Company’s asset protection products and systems, including equipment and instrumentation, predominantly in the United States.
Given the role our solutions play in enhancing the safe and efficient operation of infrastructure, we have historically provided a majority of our solutions to our customers on a regular, recurring basis. We perform these services largely at our customers’ facilities, while primarily servicing our aerospace customers at our network of state-of-the-art, in-house laboratories. These solutions typically include NDT and inspection services, and can also include a wide range of mechanical services, including heat tracing, pre-inspection insulation stripping, coating applications, re-insulation, engineering assessments and long-term condition-monitoring. Under this business model, many customers outsource their inspection to us on a “run and maintain” basis. We have established long-term relationships as a critical solutions provider to many of the leading companies with asset-intensive infrastructure in our target markets. These markets include companies in the oil and gas, aerospace and defense, industrials, power generation and transmission (including alternative and renewable energy), other process industries and infrastructure, research and engineering and other industries.
We have focused on providing our advanced asset protection solutions to our customers using proprietary, technology-enabled software and testing instruments, including those developed by our Products and Systems segment. We have made numerous acquisitions in an effort to grow our base of experienced, certified personnel, expand our service lines and technical capabilities, increase our geographical reach, complement our existing offerings, and leverage our fixed costs. We have increased our capabilities and the size of our customer base through the development of applied technologies and managed support services, organic growth and the integration of acquired companies. These acquisitions have provided us with additional service lines, technologies, resources and customers which we believe will enhance our advantages over our competition.
We believe long-term growth can be realized in our target markets. Our level of business and financial results are impacted by world-wide macro- and micro-economic conditions generally, as well as those within our target markets. Among other things, we expect the timing of our oil and gas customers inspection spend to be impacted by oil price fluctuations.
We have continued providing our customers with an innovative asset protection software ecosystem through our MISTRAS OneSuite platform. The software platform offers functions of MISTRAS' popular software and services brands as integrated apps on a cloud environment. OneSuite serves as a single access portal for customers' data activities and provides access to 90 plus applications being offered on one centralized platform.
Recent Developments
The Russian-Ukrainian war and the conflict in the Middle East between Israel and Hamas are creating disruptions in the oil and gas market and the supply chain in general, which is resulting in some disruption to our business operations primarily in Europe due to increased energy costs.

Our cash position and liquidity remains strong. As of June 30, 2024, the cash balance was approximately $17.2 million, and with our Credit Agreement, provides us with significant liquidity.
In April 2021, the Biden Administration announced aggressive initiatives to battle climate change, which includes a significant reduction in the use of fossil fuels and a transition to electric vehicles and increased use of alternative energy. Any legislation or regulations that may be adopted to implement these measures may negatively impact our customers in the oil and gas market over the long-term, which presently is our largest market, although this initiative will likely benefit the alternative energy market, such as wind energy, for which we provide products and services. At this time, it is difficult to determine the magnitude and timing of the impact that climate change initiatives and legislation, if any, will have on these markets and the resulting impact on our business and operational results.
The Company is currently unable to predict with certainty the overall impact that the factors discussed above and the effect of inflationary pressures may have on its business, results of operations or liquidity or in other ways which the Company cannot yet determine. The Company’s European operations are currently experiencing higher energy costs, among other increased costs, due in part to the Russian-Ukrainian war and the conflict in the Middle East between Israel and Hamas. The Company will continue to monitor market conditions and respond accordingly.
Note About Non-GAAP Measures
The Company prepares its consolidated financial statements in accordance with U.S. generally accepted accounting principles ("GAAP"). In this MD&A under the heading "Income (loss) from Operations", 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", with tables reconciling the measure to a financial measure under GAAP. This presentation excludes from "Income (loss) from Operations" (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. Our management uses this non-GAAP measure 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. We believe investors and other users of our financial statements benefit from the presentation of this non-GAAP measure in evaluating our performance. Income (loss) before special items excludes the identified adjustments, which provides additional tools to compare our core business operating performance on a consistent basis and measure underlying trends and results in our business. Income (loss) before special items is not used to determine incentive compensation for executives or employees, nor is it a replacement for the reported GAAP financial performance and/or necessarily comparable to the non-GAAP financial measures of other companies. Any measure that eliminates the foregoing items 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 may not be calculated in the same manner by all companies, this measure may not be comparable to other similarly titled measures used by other companies.

Our effective income tax rate was approximately 15.5% and (974.3)% for the three months ended June 30, 2024 and 2023, respectively. Our effective income tax rate was approximately 14.9% and 21.5% for the six months ended June 30, 2024 and 2023, respectively.
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 such as the reversal of valuation allowances. The effective income tax rate for the six months ended June 30, 2023 was higher than the statutory rate due primarily to a $0.7 million valuation allowance recorded during the period which was related to a foreign jurisdiction.
The effective income tax rate for the six months ended June 30, 2024 was lower than the statutory rate due primarily to items such as the reversal of valuation allowances. The effective income tax rate for the six months ended June 30, 2023 was lower than the statutory rate due primarily to an unfavorable discrete item related to stock compensation.
Income tax expense varies as a function of pre-tax income and the level of non-deductible expenses, such as certain amounts of meals and entertainment expense, valuation allowances, and other permanent differences. It is also affected by discrete items that may occur in any given year but are not consistent from year to year. Our effective income tax rate may fluctuate over the next few years due to many variables including the amount and future geographic distribution of our pre-tax income, changes resulting from our acquisition strategy, and increases or decreases in our permanent differences.
