1.    Description of Business and Basis of Presentation

Description of Business

Mistras Group, Inc. and 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 and 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. During the first quarter of 2023, the Company renamed the Services segment to more closely align to the geographical area in which the Segment operates. We did not recast the corresponding financial information for the historical periods presented, as there was no change in the manner which our chief operating decision maker reviews the financial results of each Segment and allocates resources. Our Segments, with the updated naming convention, are as follows:

•North America (Referred to as "Services" in prior filings). 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.

During 2022, the Company experienced unfavorable foreign currency exchange impacts as it relates to the Company's European operations, which has continued in 2023. Additionally, the Russian-Ukrainian war 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

Notes to Unaudited Condensed Consolidated Financial Statements

(tabular dollars and shares in thousands, except per share data)

Company’s European operations are currently experiencing increased costs associated with higher energy costs, among others, due in part to the Russian-Ukrainian war.

In 2022, the Company eliminated substantially all of the COVID related cost reduction initiatives undertaken in 2020, including re-installment of the savings plan employer match and increasing wages back to pre-pandemic amounts.

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 presentation of the results for the interim periods of the years ending December 31, 2023 and December 31, 2022.

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 2022 Annual Report on Form 10-K ("2022 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 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 2022 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 2022 Annual Report, there have been no material changes to the Company's significant accounting policies.

Income Taxes

As of March 31, 2023, 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.

Notes to Unaudited Condensed Consolidated Financial Statements

(tabular dollars and shares in thousands, except per share data)

The Company’s effective income tax rate was approximately 15.6% and 19.3% for the three months ended March 31, 2023 and 2022, respectively. The effective income tax rate benefit for the three months ended March 31, 2023 was lower than the statutory rate primarily due to the impact of an unfavorable discrete item related to stock compensation.

Recent Accounting Pronouncements

In March 2020 and updated in January 2021, the FASB issued Accounting Standards Update ("ASU") 2020-04 and 2021-01, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The amendments provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The guidance provides optional expedients and exceptions for applying U.S. GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another rate that is expected to be discontinued. The amendments in ASU 2020-04 are effective for all entities as of March 12, 2020 through December 31, 2024. The Company is currently evaluating applicable contracts and the available expedients provided by the new guidance.

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.

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 (MSAs) 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 three months ended March 31, 2023 and 2022 that was included in the contract liability balance at the beginning of such year was $3.1 million and $2.2 million 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 a practical expedient to expense incremental costs incurred related to obtaining a contract. 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 has granted share-based incentive awards to its eligible employees and non-employee directors under two equity incentive plans: (i) the 2009 Long-Term Incentive Plan (the "2009 Plan") and (ii) the 2016 Long-Term Incentive Plan (the "2016 Plan"). No awards have been granted under the 2009 Plan since the 2016 Plan was approved by shareholders in 2016, and the remaining stock option award granted under the 2009 Plan expired during the three months ended March 31, 2022. 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 restricted stock units, stock appreciation rights and deferred stock rights. At the annual shareholders meeting on May 23, 2022, the Company’s shareholders approved an amendment to increase the total number of shares that may be issued under the 2016 Plan by 1.2 million, for a total of 4.9 million shares that are authorized for issuance under the 2016 Plan, of which approximately 1,100,000 shares were available for future grants as of March 31, 2023.

Stock Options

During the three months ended March 31, 2022, all remaining outstanding stock options expired. For each of the three months ended March 31, 2023 and 2022, the Company did not recognize any share-based compensation expense related to the stock option award.

Restricted Stock Unit Awards

For the three months ended March 31, 2023 and March 31, 2022, the Company recognized share-based compensation expense related to restricted stock unit awards of $0.9 million and $0.9 million, respectively. As of March 31, 2023, there was $10.0 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 3.1 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.

A summary of the vesting activity of restricted stock unit awards, with the respective fair value of the awards, is as follows:

	Three months ended March 31,
	2023		2022
Restricted stock awards vested	338		226

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 is 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 2022, the Compensation Committee utilized the same structure for the Company’s equity incentive compensation plan for its executive officers as 2021, and approved the new target awards for 2022. The three metrics were:

1.Free Cash Flow 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.Total Shareholder Return (TSR) measures the total return to shareholders of the Company during 2021 versus the total return to the shareholders of a predefined peer group of companies that provide inspection, testing, certification or similar industrial services. The return will be measured by the year over year percent change in share price. The share prices used to calculate the return are the average share price during the 20-trading day period ending on the initial measurement date (the last 20 trading days of 2021), compared to the average share price during the 20-trading day period ending on the final measurement date (the last 20 trading days of 2022). Any cash dividends or distributions paid in 2022 will be added to calculate the return to shareholders during the year. TSR is considered a market condition for which the fair value of PRSUs with this condition is determined using a Monte Carlo valuation model. Key assumptions in the Monte Carlo valuation model included:

a.Expected Volatility. Expected volatility of the Company’s common stock at the date of grant was estimated based on a historical average volatility rate for the approximate 1-year performance period.

b.Dividend Yield. The dividend yield assumption was based on historical and anticipated dividend payouts (assumed at zero).

c.Risk-Free Interest Rate. The risk-free interest rate assumption was based on observed interest rates consistent with the approximate 1-year performance measurement period.

For 2023, the Compensation Committee made changes to the Company's equity incentive compensation plan for its executive officers including modifying the metrics utilized, and approved the new target awards for 2023. The three metrics are:

1.Free Cash Flow 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

PRSUs are equity-classified and compensation costs are initially measured using the fair value of the underlying stock at the date of grant. Compensation costs related to the PRSUs 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. PRSUs generally vest ratably on each of the first four anniversary dates upon completion of the performance period, for a total requisite service period of up to five years and have no dividend rights.

Outstanding at end of period:	382	$	9.12	656	$	12.18

During the three months ended March 31, 2023 and March 31, 2022, the Compensation Committee approved the final calculation of the award metrics for calendar year 2022 and 2021, respectively. As a result, the calendar year 2023 PRSUs decreased by approximately 32,000 units as a result of the final calculation of award metrics.

For the three months ended March 31, 2023 and March 31, 2022, the Company recognized aggregate share-based compensation expense related to the awards described above of approximately $0.7 million and $0.3 million, respectively. At March 31, 2023, there was $2.8 million of total unrecognized compensation costs related to approximately 382,000 non-vested PRSUs, which is expected to be recognized over a remaining weighted-average period of 2.0 years.

4.    Earnings (loss) per Share

Basic earnings (loss) per share is computed by dividing net loss by the weighted-average number of shares outstanding during the period. Diluted earnings per share is computed by dividing net 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.

These amounts are included in the trade accounts receivable balances above. Unbilled revenue is generally billed in the subsequent quarter to their revenue recognition. The Company considers unbilled receivables as short-term in nature as they are normally converted to trade receivables within 90 days, thus future changes in economic conditions will not have a significant effect on the credit loss estimate.

The Company was contracted to perform inspections of welds on various pipeline projects in Texas for a customer. As of December 31, 2019, approximately $1.4 million of past due receivables were outstanding from this customer. The Company received notice from the customer in December 2019, alleging that the work performed was not in compliance with the contract. The Company filed a lawsuit to recover the $1.4 million and other amounts due to the Company and the customer filed a counterclaim, alleging breach of contract and seeking its damages. The Company recorded a full reserve for this receivable during 2019 and the status of this situation has not changed since 2019 through March 31, 2023.

Senior Credit Facility

Prior to entering into the Credit Agreement (defined and described below), the Company had a credit agreement with its banking group (the "Prior Credit Agreement") which provided the Company with a $150 million revolving credit facility and a $100 million term loan. The Prior Credit Agreement was most recently amended on May 19, 2021 and had a maturity date of December 12, 2023.

On August 1, 2022, the Company entered into a new credit agreement (the “Credit Agreement”) which replaced the Prior Credit Agreement and provides the Company with a $190 million 5-year committed revolving credit facility and a $125 million term loan with a balance of $120 million as of March 31, 2023. The Credit Agreement permits the Company to borrow up to $100 million in non-US 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.

19

Mistras Group, Inc. and Subsidiaries

Notes to Unaudited Condensed Consolidated Financial Statements

(tabular dollars and shares in thousands, except per share data)

•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 New 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.

•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.

The Credit Agreement was accounted for as a modification and the Company expensed $0.8 million in unamortized capitalized debt issuance costs and fees during the three months ended September 30, 2022, which was included in selling, general and administrative expenses on the Consolidated Statements of Income (Loss). The Company incurred $1.6 million in financing costs for the Credit Agreement, of which $0.2 million of third party costs were expensed and included in selling, general and administrative expenses on the Consolidated Statements of Income (Loss) during the three months ended September 30, 2022.

As of March 31, 2023, the Company had borrowings of $185.0 million and a total of $2.6 million of letters of credit outstanding under the Credit Agreement. The Company has capitalized costs associated with debt modifications of $1.4 million as of March 31, 2023, 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 March 31, 2023, the Company was in compliance with the terms and covenants of the Credit Agreement. The Company continuously monitors compliance with the covenants contained in the Credit Agreement.

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 March 31, 2023, there was an aggregate of approximately $4.3 million outstanding, payable at various times through 2030. Monthly payments range from $0.7 thousand to $16 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

20

Mistras Group, Inc. and Subsidiaries

Notes to Unaudited Condensed Consolidated Financial Statements

(tabular dollars and shares in thousands, except per share data)

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:

 

	Three months ended March 31,
	2023		2022
Beginning balance	$	938	$	1,831
Payments	(938)		(938)
Revaluation	—		45
Ending balance	$	—	$	938

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. The Company cannot predict with certainty the ultimate resolution of lawsuits, investigations and claims asserted against it. Except for possible losses from the matters described below, 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 was contracted to perform inspections of welds on various pipeline projects in Texas for a customer. As of March 31, 2023, approximately $1.4 million of past due receivables were outstanding from this customer. The customer provided the Company with notice in December 2019, alleging that the Company’s inspection of 66 welds (out of approximately 16,000 welds inspected) were not in compliance with the contract, claimed approximately $7.6 million in damages, and requested that the Company pay these damages and any other damages incurred. The Company filed a lawsuit in the District Court of Bexar County, Texas, 37th Judicial District on December 17, 2019, in an action captioned Mistras Group, Inc. v. Epic Y-Grade Pipeline LP, to recover the $1.4 million and other amounts due to the Company. The customer filed a counterclaim on March 6, 2020, alleging breach of contract and seeking recovery of its alleged damages. The Company believes that any successful claim by the customer regarding the Company’s workmanship will be covered by insurance, subject to payment of a deductible. At this time, the Company is unable to determine whether it has any liability in connection with this matter and if so, the amount or range of any such liability. In the year ended December 31, 2022, the Company recorded a charge of $0.1 million for a potential loss from this matter. The Company recorded a reserve in the amount of $1.4 million during the twelve months ended December 31, 2019 for these past due receivables. See Note 16 - Subsequent Events, for updated information on this matter.

Notes to Unaudited Condensed Consolidated Financial Statements

(tabular dollars and shares in thousands, except per share data)

Two proceedings have been filed in California Superior Court for the County of Los Angeles regarding alleged violations of the California Labor Code. Both cases are captioned Justin Price v. Mistras Group, Inc., one being a purported class action lawsuit on behalf of current and former Mistras employees in California, filed on June 10, 2020, and the other was filed on September 18, 2020, behalf of the State of California under the California Private Attorney General Act on the basis of the same alleged violations. The two cases was consolidated and requested payment of all damages, including unpaid wages, and various fines and penalties available under California law. On May 4, 2021, the Company agreed to a settlement of all claims in the cases, which was more formally documented pursuant to a settlement agreement completed October 5, 2021, as amended as of May 3, 2022. Pursuant to the settlement, the Company agreed to pay $2.3 million to resolve the allegations in these proceedings and to be responsible for the employer portion of payroll taxes on the amount of the settlement allocated to wages. The settlement as agreed upon by the parties received final court approval on September 26, 2022, and the Company paid the settlement proceeds and related payroll taxes to the claims administrator in the fourth quarter of 2022. The Company recorded expense of approximately $1.6 million during the three months ended March 31, 2021 related to this settlement, which is in addition to expense of $0.8 million the Company recorded during the three months ended December 31, 2020.

Pension Related Contingencies

Certain of 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 the subsidiary 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 March 31, 2023 is approximately $2.5 million, which were incurred in 2018 and 2019.

Severance and labor disputes

During December 2019, the Company executed an agreement to sell the rights of certain customer "staff leasing" contracts related to its German subsidiary for total consideration of approximately $0.1 million, effective January 1, 2020. No other assets or liabilities other than those employee benefits related to employees working on the customer contracts were included in the sale. As of March 31, 2023, the Company has approximately $0.1 million of accrued estimated severance payment obligations, which takes into account the Company's estimate with respect to the employees that have been or will be transitioned to the German subsidiaries' other customers. The $0.2 million of estimated obligations is net of $0.4 million in payments made and $1.0 million in reversals due to employees being transitioned to customer contracts.

15.    Segment Disclosure

As noted in Note 1-Description of Business and Basis of Presentation, the Company updated the naming convention of one of our three operating segments and the updates are reflected below. Our 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.

•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

(tabular dollars and shares in thousands, except per share data)

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.

16.    Subsequent Events

On April 25, 2023, the Company settled the outstanding litigation described in Note 14-Commitments and Contingencies, Mistras Group, Inc. v. Epic Y-Grade Pipeline LP, pending in Texas state court. The lawsuit involves a claim against a customer for unpaid receivables and the customer’s counterclaim related to inspection of welds on various pipeline projects in Texas. The settlement will result in a payment by the Company of $0.3 million (which the Company estimates is significantly less than the cost of going to trial) and a release of its claim for $1.4 million of associated past due receivables which were fully reserved for in prior periods. The settlement is contingent on the parties executing a settlement agreement, which will include a release of all claims related to the matter and dismissal of the case with prejudice.

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 2022 Annual Report as well as those discussed in this Quarterly Report on Form 10-Q 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

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.

(tabular dollars are in thousands)

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 (which we previously referred to as our Services segment), 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.

We have continued to develop new technologies to provide monitoring of wind blade integrity through our Sensoria™ tool. Sensoria helps provide real-time monitoring and damage detection of wind turbine blades and allows our customers to maximize uptime, performance and safety of wind turbine blades. This tool provides additional growth and expansion of our capabilities to serve both new and existing wind turbines and greatly enhances our product offerings within the renewable energy industry.

Recent Developments

Issues related to the COVID-19 coronavirus (COVID-19) pandemic have subsided significantly during 2023 as compared to 2022. The Russian-Ukrainian war is creating disruption in the oil and gas market and the supply chain in general, which is resulting in some disruption to our business operations.

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.

Earlier in 2022, the Company eliminated substantially all of the COVID related cost reduction initiatives undertaken in 2020, including re-installment of the savings plan employer match and increasing wages back to pre-pandemic amounts. Our cash position and liquidity remains strong. As of March 31, 2023, the cash balance was approximately $16.7 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. 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. 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.

Midstream	21,231		24,907
Downstream	40,495		37,051
Total	$	98,665	$	94,223

For the three months ended March 31, 2022, the Company reclassified $9.4 million from Upstream to Downstream in order to reflect the proper classification in the current period. Oil and gas upstream customer revenue increased approximately $4.7 million, or 14%, due primarily to market share gains and increased exploration activity as compared to the prior period. Midstream customer revenues decreased approximately $(3.7) million, or (15)%, due to decreased pipe inspection services performed as compared to the prior year quarter. Downstream customer revenues increased $3.4 million or, 9%, primarily due to increased customer turnarounds in the current year that were delayed in the prior period.

	Three months ended March 31,
	2023		2022
Revenue by type
Field Services	$	109,680	$	105,495

Data Solutions	16,812		12,399
Other	28,392		30,679
Total	$	168,016	$	161,662

Field Services revenues are comprised of revenue derived primarily by technicians performing asset inspections and maintenance services for our customers at locations other than Mistras properties. Field Services revenue increased by $4.2 million as compared to the prior year primarily due to increases in sales volume in our oil and gas and petrochemical end markets for our North America and International segments and increased sales volumes within our the power generation and infrastructure end markets for our Products segment.

Shop Laboratory revenues are comprised of quality assurance inspections of components and materials at our Mistras in house laboratory facilities. Shop revenues were flat as compared to the prior year quarter due to similar sales volumes related to our aerospace end market in both periods.

Data Solutions revenues are comprised of revenue derived from data software sales & subscriptions, implementation services and analytics which offer insights and generate value from asset protection. Data Solutions revenue is derived from work performed by Mistras employees in our facilities, or at customer locations. Data Solutions revenue increased by $4.4 million due to increased sales volume within PCMS, Onstream and other Data Solutions offerings within our North America segment.

Other revenues are comprised of locations that perform both asset inspection services and testing of components and materials at in house Mistras laboratories. Other revenues decreased approximately $2.3 million as compared to the prior year primarily due to decreased sales within the defense sector within the North America segment offset by increased private space shop related activities during the quarter.

Gross Profit

Gross profit increased by $6.2 million, or 15.5%, in the three months ended March 31, 2023 versus the prior year comparable period, on a increase in revenue of 3.9%.

Gross profit by segment for the three months ended March 31, 2023 and 2022 was as follows:

Gross profit margin was 27.4% and 24.7% for the three-month periods ended March 31, 2023 and 2022, respectively. North America segment realized an increase of 3.8% in gross profit margin to 26.8% during the three months ended March 31, 2023. This was primarily due to better sales mix in the period and increased rebates received for insurance claims as compared to the prior year period. International segment realized a 4.0% decrease in gross profit margin to 25.1% during the three months ended March 31, 2023 due primarily to sales mix and increased energy costs in the current period.

Three Months

For the three months ended March 31, 2023, the loss from operations (GAAP) decreased $2.9 million or 61.0%, compared with the three months ended March 31, 2022, while the income (loss) before special items (non-GAAP) improved by $5.6 million, or 104.6%. As a percentage of revenue, the income (loss) before special items improved by 340 basis points to 0.1% in the three months ended March 31, 2023 from (3.3)% in the three months ended March 31, 2022.

Interest Expense

Interest expense was approximately $4.1 million and $1.9 million for the three months ended March 31, 2023 and 2022, respectively. The increase was a result of a change in the effective interest rate, due to a lower leverage ratio and the elimination of the minimum LIBOR floor.

 Income Taxes

31

Mistras Group, Inc. and Subsidiaries

Management's Discussion and Analysis of Financial Condition and Results of Operations

(tabular dollars are in thousands)

Our effective income tax rate was approximately 15.6% and 19.3% for the three months ended March 31, 2023 and 2022, respectively.

The effective income tax rate benefit for the three months ended March 31, 2023 was lower than the statutory rate primarily due to the impact of an unfavorable discrete item related to stock compensation. The effective income tax rate for the three months ended March 31, 2022 was lower than the statutory rate primarily due to the impact of an unfavorable discrete item related to stock compensation.

On August 19, 2022, the United States enacted the Inflation Reduction Act, (the "Inflation Act"), a package intended to reduce inflation. The Inflation Act contains a variety of tax provisions, including a 15% corporate minimum tax, a tax on stock repurchases, and various tax credit opportunities. We evaluated the impact of this guidance on our consolidated financial position, results of operations, and cash flows, and it will not have a material impact.

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.

Liquidity and Capital Resources

Cash flows are summarized in the table below:

	Three months ended March 31,
	2023		2022
Net cash provided by (used in):
Operating activities	$	4,433	$	(5,399)
Investing activities	(4,460)		(2,737)
Financing activities	(3,951)		4,323
Effect of exchange rate changes on cash	207		(376)
Net change in cash and cash equivalents	$	(3,771)	$	(4,189)

Cash Flows from Operating Activities

During the three months ended March 31, 2023, cash provided by operating activities was $4.4 million, representing a year-on-year increase of $9.8 million, or 182%. The increase was primarily attributable to an improved days sales outstanding and movements in working capital, as compared to the prior year quarter.

Cash Flows from Investing Activities

During the three months ended March 31, 2023 and 2022, cash used in investing activities was $4.5 million primarily attributable to increased expenditures for vehicles leased related to customer projects that will be occurring in the remaining quarters of 2023 which did not exist in the prior period.

Cash Flows from Financing Activities

Net cash used by financing activities was $4.0 million for the three months ended March 31, 2023, compared to net cash provided by financing activities of $4.3 million for the three months ended March 31, 2022. During the three months ended March 31, 2023, net borrowings of debt were approximately $8.4 million higher as compared to 2022 resulting in debt paydown during the period. In addition, $0.2 million more taxes were paid related to net share settlement of share-based awards during the three months ended March 31, 2023.

Effect of Exchange Rate Changes on Cash and Cash Equivalents

32

The effect of exchange rate changes on our cash and cash equivalents was an increase of $0.2 million in the three months ended March 31, 2023, compared to a decrease of $0.4 million for the three months ended March 31, 2022.

Cash Balance and Credit Facility Borrowings

As of March 31, 2023, we had cash and cash equivalents totaling $16.7 million and $122.2 million of unused commitments under our Credit Agreement with borrowings of $185.0 million and $2.6 million of letters of credit outstanding. We finance operations primarily through our existing cash balances, cash collected from operations, bank borrowings and capital lease financing. We believe these sources are sufficient to fund our operations for the foreseeable future.

As of March 31, 2023, we were in compliance with the terms of the Credit Agreement and will continuously monitor our compliance with the covenants contained in the Credit Agreement.

The terms of our Credit Agreement are described in Note 12- Long-Term Debt of the Notes to the Unaudited Condensed Consolidated Financial Statements, under the heading "Senior Credit Facility".

Contractual Obligations

There have been no significant changes in our contractual obligations and outstanding indebtedness as disclosed in the 2022 Annual Report.

Off-balance Sheet Arrangements

During the three months ended March 31, 2023, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Description of Business

Mistras Group, Inc. and 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 and 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. During the first quarter of 2023, the Company renamed the Services segment to more closely align to the geographical area in which the Segment operates. We did not recast the corresponding financial information for the historical periods presented, as there was no change in the manner which our chief operating decision maker reviews the financial results of each Segment and allocates resources. Our Segments, with the updated naming convention, are as follows:

•North America (Referred to as "Services" in prior filings). 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.

During 2022, the Company experienced unfavorable foreign currency exchange impacts as it relates to the Company's European operations, which has continued in 2023. Additionally, the Russian-Ukrainian war 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.

In 2022, the Company eliminated substantially all of the COVID related cost reduction initiatives undertaken in 2020, including re-installment of the savings plan employer match and increasing wages back to pre-pandemic amounts.

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 presentation of the results for the interim periods of the years ending December 31, 2023 and December 31, 2022.

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 2022 Annual Report on Form 10-K ("2022 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 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 2022 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 2022 Annual Report, there have been no material changes to the Company's significant accounting policies.

Income Taxes

As of March 31, 2023, 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 15.6% and 19.3% for the three months ended March 31, 2023 and 2022, respectively. The effective income tax rate benefit for the three months ended March 31, 2023 was lower than the statutory rate primarily due to the impact of an unfavorable discrete item related to stock compensation.

Recent Accounting Pronouncements

In March 2020 and updated in January 2021, the FASB issued Accounting Standards Update ("ASU") 2020-04 and 2021-01, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The amendments provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The guidance provides optional expedients and exceptions for applying U.S. GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another rate that is expected to be discontinued. The amendments in ASU 2020-04 are effective for all entities as of March 12, 2020 through December 31, 2024. The Company is currently evaluating applicable contracts and the available expedients provided by the new guidance.

Revenue from Contract with Customer [Abstract]

Revenue

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.

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 (MSAs) 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 three months ended March 31, 2023 and 2022 that was included in the contract liability balance at the beginning of such year was $3.1 million and $2.2 million 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 a practical expedient to expense incremental costs incurred related to obtaining a contract. 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.

Share-Based Compensation

3 Months Ended

Mar. 31, 2023

Share-Based Payment Arrangement [Abstract]

Share-Based Compensation

Share-Based Compensation

The Company has granted share-based incentive awards to its eligible employees and non-employee directors under two equity incentive plans: (i) the 2009 Long-Term Incentive Plan (the "2009 Plan") and (ii) the 2016 Long-Term Incentive Plan (the "2016 Plan"). No awards have been granted under the 2009 Plan since the 2016 Plan was approved by shareholders in 2016, and the remaining stock option award granted under the 2009 Plan expired during the three months ended March 31, 2022. 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 restricted stock units, stock appreciation rights and deferred stock rights. At the annual shareholders meeting on May 23, 2022, the Company’s shareholders approved an amendment to increase the total number of shares that may be issued under the 2016 Plan by 1.2 million, for a total of 4.9 million shares that are authorized for issuance under the 2016 Plan, of which approximately 1,100,000 shares were available for future grants as of March 31, 2023.

Stock Options

During the three months ended March 31, 2022, all remaining outstanding stock options expired. For each of the three months ended March 31, 2023 and 2022, the Company did not recognize any share-based compensation expense related to the stock option award.

Restricted Stock Unit Awards

For the three months ended March 31, 2023 and March 31, 2022, the Company recognized share-based compensation expense related to restricted stock unit awards of $0.9 million and $0.9 million, respectively. As of March 31, 2023, there was $10.0 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 3.1 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.

A summary of the vesting activity of restricted stock unit awards, with the respective fair value of the awards, is as follows:

	Three months ended March 31,
	2023		2022
Restricted stock awards vested	338		226
Fair value of awards vested	$	1,946	$	1,502

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 is 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 2022, the Compensation Committee utilized the same structure for the Company’s equity incentive compensation plan for its executive officers as 2021, and approved the new target awards for 2022. The three metrics were:

1.Free Cash Flow 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.Total Shareholder Return (TSR) measures the total return to shareholders of the Company during 2021 versus the total return to the shareholders of a predefined peer group of companies that provide inspection, testing, certification or similar industrial services. The return will be measured by the year over year percent change in share price. The share prices used to calculate the return are the average share price during the 20-trading day period ending on the initial measurement date (the last 20 trading days of 2021), compared to the average share price during the 20-trading day period ending on the final measurement date (the last 20 trading days of 2022). Any cash dividends or distributions paid in 2022 will be added to calculate the return to shareholders during the year. TSR is considered a market condition for which the fair value of PRSUs with this condition is determined using a Monte Carlo valuation model. Key assumptions in the Monte Carlo valuation model included:

a.Expected Volatility. Expected volatility of the Company’s common stock at the date of grant was estimated based on a historical average volatility rate for the approximate 1-year performance period.

b.Dividend Yield. The dividend yield assumption was based on historical and anticipated dividend payouts (assumed at zero).

c.Risk-Free Interest Rate. The risk-free interest rate assumption was based on observed interest rates consistent with the approximate 1-year performance measurement period.

For 2023, the Compensation Committee made changes to the Company's equity incentive compensation plan for its executive officers including modifying the metrics utilized, and approved the new target awards for 2023. The three metrics are:

1.Free Cash Flow 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

PRSUs are equity-classified and compensation costs are initially measured using the fair value of the underlying stock at the date of grant. Compensation costs related to the PRSUs 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. PRSUs generally vest ratably on each of the first four anniversary dates upon completion of the performance period, for a total requisite service period of up to five years and have no dividend rights.

A summary of the Company's PRSU activity is as follows:

	Three months ended March 31,
	2023			2022
	Units	Weighted Average Grant-Date Fair Value		Units	Weighted Average Grant-Date Fair Value
Outstanding at beginning of period:	280	$	9.96	388	$	10.07
Granted	282	$	8.50	341	$	6.55
Performance condition adjustments	(32)	$	6.55	(56)	$	10.47
Released	(64)	$	5.58	(17)	$	6.85
Forfeited	(84)	$	6.95	—	$	—
Outstanding at end of period:	382	$	9.12	656	$	12.18

During the three months ended March 31, 2023 and March 31, 2022, the Compensation Committee approved the final calculation of the award metrics for calendar year 2022 and 2021, respectively. As a result, the calendar year 2023 PRSUs decreased by approximately 32,000 units as a result of the final calculation of award metrics.

For the three months ended March 31, 2023 and March 31, 2022, the Company recognized aggregate share-based compensation expense related to the awards described above of approximately $0.7 million and $0.3 million, respectively. At March 31, 2023, there was $2.8 million of total unrecognized compensation costs related to approximately 382,000 non-vested PRSUs, which is expected to be recognized over a remaining weighted-average period of 2.0 years.

Earnings Per Share [Abstract]

Earnings (loss) per Share

Earnings (loss) per Share

Basic earnings (loss) per share is computed by dividing net loss by the weighted-average number of shares outstanding during the period. Diluted earnings per share is computed by dividing net 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.

The following table sets forth the computations of basic and diluted loss per share:

Allowance for credit losses	(3,641)		(4,110)
Accounts receivable, net	$	120,425	$	123,657

The Company had $21.6 million and $13.5 million of unbilled revenue accrued as of March 31, 2023 and December 31, 2022, respectively. These amounts are included in the trade accounts receivable balances above. Unbilled revenue is generally billed in the subsequent quarter to their revenue recognition. The Company considers unbilled receivables as short-term in nature as they are normally converted to trade receivables within 90 days, thus future changes in economic conditions will not have a significant effect on the credit loss estimate.

The Company was contracted to perform inspections of welds on various pipeline projects in Texas for a customer. As of December 31, 2019, approximately $1.4 million of past due receivables were outstanding from this customer. The Company received notice from the customer in December 2019, alleging that the work performed was not in compliance with the contract. The Company filed a lawsuit to recover the $1.4 million and other amounts due to the Company and the customer filed a counterclaim, alleging breach of contract and seeking its damages. The Company recorded a full reserve for this receivable during 2019 and the status of this situation has not changed since 2019 through March 31, 2023. See Note 14-Commitments and Contingencies and Note 16 - Subsequent Events for additional details.

Senior Credit Facility

Prior to entering into the Credit Agreement (defined and described below), the Company had a credit agreement with its banking group (the "Prior Credit Agreement") which provided the Company with a $150 million revolving credit facility and a $100 million term loan. The Prior Credit Agreement was most recently amended on May 19, 2021 and had a maturity date of December 12, 2023.

On August 1, 2022, the Company entered into a new credit agreement (the “Credit Agreement”) which replaced the Prior Credit Agreement and provides the Company with a $190 million 5-year committed revolving credit facility and a $125 million term loan with a balance of $120 million as of March 31, 2023. The Credit Agreement permits the Company to borrow up to $100 million in non-US 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 New 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.

•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.

The Credit Agreement was accounted for as a modification and the Company expensed $0.8 million in unamortized capitalized debt issuance costs and fees during the three months ended September 30, 2022, which was included in selling, general and administrative expenses on the Consolidated Statements of Income (Loss). The Company incurred $1.6 million in financing costs for the Credit Agreement, of which $0.2 million of third party costs were expensed and included in selling, general and administrative expenses on the Consolidated Statements of Income (Loss) during the three months ended September 30, 2022.

As of March 31, 2023, the Company had borrowings of $185.0 million and a total of $2.6 million of letters of credit outstanding under the Credit Agreement. The Company has capitalized costs associated with debt modifications of $1.4 million as of March 31, 2023, 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 March 31, 2023, the Company was in compliance with the terms and covenants of the Credit Agreement. The Company continuously monitors compliance with the covenants contained in the Credit Agreement.

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 March 31, 2023, there was an aggregate of approximately $4.3 million outstanding, payable at various times through 2030. Monthly payments range from $0.7 thousand to $16 thousand and interest rates range from 0.4% to 3.5%.

Fair Value Disclosures [Abstract]

Fair Value Measurements

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:

 

	Three months ended March 31,
	2023		2022
Beginning balance	$	938	$	1,831
Payments	(938)		(938)
Revaluation	—		45
Ending balance	$	—	$	938

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.

Commitments and Contingencies

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. The Company cannot predict with certainty the ultimate resolution of lawsuits, investigations and claims asserted against it. Except for possible losses from the matters described below, 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 was contracted to perform inspections of welds on various pipeline projects in Texas for a customer. As of March 31, 2023, approximately $1.4 million of past due receivables were outstanding from this customer. The customer provided the Company with notice in December 2019, alleging that the Company’s inspection of 66 welds (out of approximately 16,000 welds inspected) were not in compliance with the contract, claimed approximately $7.6 million in damages, and requested that the Company pay these damages and any other damages incurred. The Company filed a lawsuit in the District Court of Bexar County, Texas, 37th Judicial District on December 17, 2019, in an action captioned Mistras Group, Inc. v. Epic Y-Grade Pipeline LP, to recover the $1.4 million and other amounts due to the Company. The customer filed a counterclaim on March 6, 2020, alleging breach of contract and seeking recovery of its alleged damages. The Company believes that any successful claim by the customer regarding the Company’s workmanship will be covered by insurance, subject to payment of a deductible. At this time, the Company is unable to determine whether it has any liability in connection with this matter and if so, the amount or range of any such liability. In the year ended December 31, 2022, the Company recorded a charge of $0.1 million for a potential loss from this matter. The Company recorded a reserve in the amount of $1.4 million during the twelve months ended December 31, 2019 for these past due receivables. See Note 16 - Subsequent Events, for updated information on this matter.

Two proceedings have been filed in California Superior Court for the County of Los Angeles regarding alleged violations of the California Labor Code. Both cases are captioned Justin Price v. Mistras Group, Inc., one being a purported class action lawsuit on behalf of current and former Mistras employees in California, filed on June 10, 2020, and the other was filed on September 18, 2020, behalf of the State of California under the California Private Attorney General Act on the basis of the same alleged violations. The two cases was consolidated and requested payment of all damages, including unpaid wages, and various fines and penalties available under California law. On May 4, 2021, the Company agreed to a settlement of all claims in the cases, which was more formally documented pursuant to a settlement agreement completed October 5, 2021, as amended as of May 3, 2022. Pursuant to the settlement, the Company agreed to pay $2.3 million to resolve the allegations in these proceedings and to be responsible for the employer portion of payroll taxes on the amount of the settlement allocated to wages. The settlement as agreed upon by the parties received final court approval on September 26, 2022, and the Company paid the settlement proceeds and related payroll taxes to the claims administrator in the fourth quarter of 2022. The Company recorded expense of approximately $1.6 million during the three months ended March 31, 2021 related to this settlement, which is in addition to expense of $0.8 million the Company recorded during the three months ended December 31, 2020.

Pension Related Contingencies

Certain of 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 the subsidiary 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 March 31, 2023 is approximately $2.5 million, which were incurred in 2018 and 2019.

Severance and labor disputes

During December 2019, the Company executed an agreement to sell the rights of certain customer "staff leasing" contracts related to its German subsidiary for total consideration of approximately $0.1 million, effective January 1, 2020. No other assets or liabilities other than those employee benefits related to employees working on the customer contracts were included in the sale. As of March 31, 2023, the Company has approximately $0.1 million of accrued estimated severance payment obligations, which takes into account the Company's estimate with respect to the employees that have been or will be transitioned to the German subsidiaries' other customers. The $0.2 million of estimated obligations is net of $0.4 million in payments made and $1.0 million in reversals due to employees being transitioned to customer contracts.

Segment Disclosure

Segment Disclosure

As noted in Note 1-Description of Business and Basis of Presentation, the Company updated the naming convention of one of our three operating segments and the updates are reflected below. Our 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.

•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.

Accounting Policies [Abstract]

Basis of Presentation

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 presentation of the results for the interim periods of the years ending December 31, 2023 and December 31, 2022.

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 2022 Annual Report on Form 10-K ("2022 Annual Report").

Principles of Consolidation

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 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

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.

Income Taxes

Income Taxes

As of March 31, 2023, 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 15.6% and 19.3% for the three months ended March 31, 2023 and 2022, respectively. The effective income tax rate benefit for the three months ended March 31, 2023 was lower than the statutory rate primarily due to the impact of an unfavorable discrete item related to stock compensation.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In March 2020 and updated in January 2021, the FASB issued Accounting Standards Update ("ASU") 2020-04 and 2021-01, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The amendments provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The guidance provides optional expedients and exceptions for applying U.S. GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another rate that is expected to be discontinued. The amendments in ASU 2020-04 are effective for all entities as of March 12, 2020 through December 31, 2024. The Company is currently evaluating applicable contracts and the available expedients provided by the new guidance.

Revenue

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.

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 (MSAs) 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.

Fair Value Measurements

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.

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.

Segment Reporting

Segment Disclosure

As noted in Note 1-Description of Business and Basis of Presentation, the Company updated the naming convention of one of our three operating segments and the updates are reflected below. Our 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.

•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.
