1. Description of Business and Basis of Presentation

Description of Business

Mistras Group, Inc., together with its subsidiaries (the "Company"), is a global leader in technology-enabled industrial asset integrity solutions, serving critical industries including oil & gas, aerospace & defense, power & utilities, manufacturing, and civil infrastructure.

The Company provides a diversified portfolio of products and services, ranging from advanced non-destructive testing ("NDT") and pipeline inspections to real-time condition monitoring, maintenance planning, and specialized engineering, powered by a proprietary management software suite that centralizes integrity data for predictive analytics and benchmark analysis. With a long-standing track record of innovation and deep industry expertise, the Company helps clients reduce risk, extend asset life, and optimize operational performance.

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.

The Company’s core capabilities include NDT field inspections enhanced by advanced robotics, laboratory quality control, laboratory materials services, shop laboratory assurance testing, sensing technologies and NDT equipment, asset and mechanical integrity engineering services, and light mechanical maintenance and access services.

The Company has three operating segments. Our segments are as follows:

•North America: This segment provides asset protection solutions predominantly in North America, with the largest concentration in the United States, followed by Canada, consisting primarily of NDT, inspection, mechanical and engineering services that are used to evaluate the safety, structural integrity and reliability of critical energy, industrial and public infrastructure and commercial aerospace components. Software, digital and data services are included in this segment.

•International: This segment offers services, products and systems similar to those of the other segments to select markets within Europe, the Middle East, Africa, Asia and South America, but not to customers in China and South Korea, which are served by the Products and Systems segment.

•Products and Systems: This segment designs, manufactures, sells, installs and services the Company’s asset protection products and systems, including equipment and instrumentation, predominantly in the United States.

Recent Developments

On September 17, 2026, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Athena Purchaser, LLC, a Delaware limited liability company (“Parent”), and Athena Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Acquisition Sub”), pursuant to which, subject to the terms and conditions of the Merger Agreement, Acquisition Sub will be merged with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Parent. Parent and Acquisition Sub are controlled by funds affiliated with H.I.G. Capital (“H.I.G.”).

Pursuant to the terms of the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of the Company’s common stock, par value $0.01 per share, issued and outstanding immediately prior to the Effective Time (other than (i) shares held by the Company as treasury stock or held directly by Parent or Acquisition Sub, which will be automatically cancelled for no consideration, and (ii) shares held by stockholders who have properly exercised and not withdrawn their appraisal rights under Section 262 of the General Corporation Law of the State of Delaware) will be automatically converted into the right to receive $20.35 in cash, without interest.

Improvements Act of 1976, as amended (the “HSR Act”), the receipt of certain required regulatory approvals, and the satisfaction or waiver of certain other customary closing conditions. Effective October 22, 2026, the Federal Trade Commission granted early termination of the HSR Act waiting period. If the Merger is completed, the Company’s common stock will be delisted from the New York Stock Exchange (the "NYSE") and deregistered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

The foregoing description of the Merger Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement, a copy of which is filed as Exhibit 2.1 to this Quarterly Report on Form 10-Q and is incorporated herein by reference.

On August 5, 2026, the Company entered into an amendment (the “Amendment”) to its credit agreement dated August 1, 2022 (as amended, the "Credit Agreement") with the lenders party thereto and JPMorgan Chase Bank, N.A., as administrative agent. The Amendment extended the maturity date of the revolving credit facility and term loan under the Credit Agreement from July 30, 2027 to July 28, 2028. The terms related to the Amendment are described in Note 11 - Long-Term Debt.

The global trade landscape continues to be highly volatile. During 2025, the U.S. government implemented a series of trade tariffs on goods imported into the U.S. from various countries, many of which prompted reciprocal tariffs and other trade measures affecting U.S. exports. The ongoing tariff environment remains complex and continues to evolve as legal proceedings and trade negotiations progress. In February 2026, the U.S. Supreme Court ruled that the International Emergency Economic Powers Act ("IEEPA"), which the U.S. government relied upon to impose certain tariffs, does not authorize the imposition of tariffs. Following that decision, the U.S. Court of International Trade directed the U.S. Customs and Border Protection ("CBP") to begin processing refunds of previously collected IEEPA tariffs, and CBP has since processed refund claims in phases, most recently commencing in October 2026 the processing of refunds for certain finally liquidated entries. In October 2026, the U.S. Court of International Trade also certified a class of importers seeking IEEPA tariff refunds and the U.S. government’s appeals in the refund litigation remain pending. In response to the U.S. Supreme Court's ruling, the U.S. administration implemented replacement tariffs under alternative statutory authorities, including a temporary tariff under Section 122 of the Trade Act of 1974, which expired on July 24, 2026 at the end of its 150-day statutory period. The U.S. Court of International Trade ruled against the Section 122 tariffs, but that ruling has been stayed pending appeal, and the related litigation remains ongoing. Effective July 24, 2026, the U.S. administration implemented additional tariffs ranging from 10% to 12.5% on imports from numerous trading partners under Section 301 of the Trade Act of 1974, which are also subject to legal challenge. Accordingly, the ultimate scope, duration and financial impact of U.S. trade measures remain uncertain. Ongoing changes to trade policies and related uncertainty may affect global economic conditions, supply chains and costs, and may reduce trade between the U.S. and impacted countries. Tariffs and trade barriers have not had a material effect on our business or results of operations during 2026 to date. However, new tariffs or other trade measures could result in increased costs for us or our suppliers and could impact the import of materials by our customers, including materials subject to our inspection and testing services, which could adversely affect demand for our services.

Geopolitical tensions in the Middle East, including the conflict involving the U.S. and Iran that began in February 2026, have contributed to increased volatility in global energy markets and broader macroeconomic uncertainty. The conflict has disrupted shipping through the Strait of Hormuz and increased uncertainty surrounding global energy supplies, international shipping routes and supply chains, contributing to fluctuations in oil and natural gas prices and increased costs for certain materials and transportation. Efforts to resolve the conflict have not been successful to date, and renewed escalation remains possible. Fluctuations in crude oil and natural gas prices may influence capital spending and maintenance activity by customers in the oil and gas sector, which could affect demand for certain of our services, particularly field inspection and asset integrity solutions. Additionally, continued instability in the Middle East could contribute to supply chain disruptions, changes in foreign currency exchange rates, and delays in customer projects. While we have not experienced material impacts to date, the situation remains dynamic, and we continue to monitor developments and assess potential impacts on our operations, financial condition, and results of operations.

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 year ended December 31, 2025 and year ending December 31, 2026.

Certain items included in these statements are based on management’s estimates. Actual results may differ from those estimates. The results of operations for any interim period are not necessarily indicative of the results expected for the year. The accompanying Unaudited Condensed Consolidated Financial Statements should be read in conjunction with the notes to the Audited Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2025 (the "2025 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 consolidated subsidiaries in which the Company’s ownership interest is less than 100%, the non-controlling interests are reported in stockholders’ equity in the accompanying Unaudited Condensed Consolidated Balance Sheets. The non-controlling interests in net results, net of tax, are classified separately in the accompanying Unaudited Condensed Consolidated Statements of Income. All significant intercompany accounts and transactions have been eliminated in consolidation.

Reclassifications

Certain amounts in prior periods have been reclassified to conform to the current year presentation. Such reclassifications did not affect the Company's consolidated 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 2025 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 2025 Annual Report, there have been no material changes to the Company’s significant accounting policies.

Income Taxes

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

As of September 30, 2026, 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 37.7% and 22.3% for the three months ended September 30, 2026 and 2025, respectively. The Company’s effective income tax rate was approximately 28.8% and 21.9% for the nine months ended September 30, 2026 and 2025, respectively.

The effective income tax rate for the three months ended September 30, 2026, was higher than the statutory rate primarily due to non-deductible transaction costs. The effective income tax rate for the three months ended September 30, 2025, was higher than the statutory rate primarily due to the impact of foreign currency losses.

The effective income tax rate for the nine months ended September 30, 2026, was higher than the statutory rate primarily due to non-deductible transactions costs. The effective income tax rate for the nine months ended September 30, 2025, was higher than the statutory rate primarily due to the impact of foreign currency losses.

On July 4, 2025, H.R.1, commonly referred to as the One Big Beautiful Bill Act ("OBBBA"), was enacted, which includes a broad range of tax reform provisions. These tax reform provisions include the extension and modification of certain provisions of the Tax Cuts and Jobs Act and were effective for calendar year 2025. The changes include, but are not limited to, immediate expensing of domestic research and development expenditure, the restoration of 100% bonus depreciation, and an EBITDA-based interest expense limitation. These provisions did not have a material impact on the Company’s financial statements for the three and nine months ended September 30, 2026.

Recent Accounting Pronouncements

On November 4, 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures, to require disaggregation of certain expense captions into specified categories in disclosures within the notes of the financial statements. The standard is effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027. Early adoption is permitted. The guidance is required to be applied prospectively and amendments in the ASU may be applied prospectively or retrospectively. We are currently evaluating the impact this standard will have on our disclosures.

In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal Use Software (ASU 2025-06). This standard clarifies capitalization thresholds for software development costs and aligns accounting treatment more closely with the economic substance of modern software development activities. ASU 2025-06 is effective for annual and interim periods beginning after December 15, 2027 on a retrospective, prospective or modified prospective basis. Early adoption is permitted. We are currently evaluating the impact this standard will have on our disclosures.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow Scope Improvements (ASU 2025-11). This standard clarifies disclosure requirements and applicability for interim financial statements. This new guidance is effective for the Company for interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The amendments in this ASU may be adopted using the prospective or retrospective methods. We are currently evaluating the impact this standard will have on our disclosures.

2. Revenue

The Company derives the majority of its revenue by providing services on a time and materials basis, which 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 Company'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.

Table of Contents

Mistras Group, Inc. and Subsidiaries

Notes to Unaudited Condensed Consolidated Financial Statements

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

The majority of the Company's revenue recognized at a point in time is related to product sales when the customer obtains control of the asset, which is generally upon shipment to the customer. Contract costs include labor, material and overhead.

The Company expects any significant remaining performance obligations to be satisfied within one year.

Contract Estimates

The majority of the Company's revenues are short-term in nature. The Company enters into master service agreements ("MSA"s) with customers that specify an overall framework and contract terms. The actual contracting to provide services or furnish products are triggered by a work order, purchase order, or some similar document issued pursuant to an 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 Unaudited Condensed 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 Unaudited Condensed 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 nine months ended September 30, 2026 and 2025 that was included in the contract liability balance at the beginning of the year was $7.6 million and $6.8 million, respectively. Changes in the contract asset and liability balances during these periods were not materially impacted by any other factors. The Company applies the practical expedient to expense incremental costs incurred related to obtaining a contract when the amortization period of the asset that the Company otherwise would have recognized is one year or less.

3. Share-Based Compensation

The Company grants share-based incentive awards to its eligible employees and non-employee directors under its Amended and Restated 2016 Long-Term Incentive Plan (the "2016 Plan"). Awards granted under the 2016 Plan may be in the form of stock options, restricted stock units and other forms of share-based incentives, including performance-based restricted stock units, stock appreciation rights and deferred stock rights. At the annual shareholders meeting on May 19, 2026, the Company’s shareholders approved an amendment to increase the total number of shares that may be issued under the 2016 Plan by 1.7 million shares, for a total of 7.9 million shares that are authorized for issuance under the 2016 Plan, of which approximately 2,031,000 shares were available for future grants as of September 30, 2026.

Stock Options

On January 6, 2025, an executive officer of the Company was granted a stock option for the purchase of 375,000 shares of the Company's common stock at an exercise price of $9.06, the closing price of the Company's common stock on the NYSE on the grant date. These stock options can be exercised any time on or after January 6, 2026, and prior to their expiration date, which is the earlier of 10 years from the grant date or one year following the date the executive officer is no longer serving as an officer, director or in any other capacity of the Company.

As of September 30, 2026, there was $7.8 million of unrecognized compensation costs related to RSU awards, which is expected to be recognized over a remaining weighted-average period of 2.6 years. Upon vesting, RSUs 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. Upon completion of the Merger Agreement, as described in Note 1 - Description of Business and Basis of Presentation, each outstanding RSU will be converted into the right to receive cash consideration in accordance with the terms of the Merger Agreement.

Performance Restricted Stock Units

The Company maintains Performance Restricted Stock Units ("PRSUs") that have been granted to select executives and senior officers, the ultimate payout of which may vary between zero and 200% of the target award, based on the Company’s performance over a one-year period based on specific metrics approved by the Compensation Committee of the Board of Directors of the Company.

For 2026, the Compensation Committee is using the following three performance metrics for PRSU awards.

1.Free Cash Flow defined as net cash provided by operating activities less purchases of property, plant, equipment and intangible assets and is subject to adjustments approved by the Compensation Committee.

2.Adjusted EBITDA defined as net income attributable to the Company plus: interest expense, provision for income taxes, depreciation and amortization, share-based compensation expense and certain acquisition related costs (including transaction due diligence costs and adjustments to the fair value of contingent consideration), foreign exchange (gain) loss and, if applicable, certain special items which are noted.

3.Revenue

For PRSUs awarded in 2026, the Compensation Committee utilized the same metrics as 2025 PRSUs, but with revised performance goals and weighting.

PRSUs are equity-classified and compensation costs related to PRSUs with performance conditions are initially measured using the fair value of the underlying stock at the date of grant. Compensation costs related to the PRSUs with performance conditions are subsequently adjusted for changes in the expected outcomes of the performance conditions. Earned PRSUs generally vest ratably in four equal annual installments over the four years following completion of the performance period, for a total requisite service period of up to five years, and have no dividend equivalent rights.

4. Earnings per Share

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

(1) For the three months ended September 30, 2025, 388,000 shares, related to stock options and 165,000 shares, related to restricted stock units were anti-dilutive and therefore were excluded from the calculation of diluted earnings per share. No shares related to restricted stock units or stock options were anti-dilutive for the three months ended September 30, 2026. For the nine months ended September 30, 2026, 6,000 shares related to RSUs were anti-dilutive and therefore were excluded from the calculation of diluted earnings per share. For the nine months ended September 30, 2025, 379,000 shares, related to stock options and 227,000 shares, related to restricted stock units were anti-dilutive and therefore were excluded from the calculation of diluted earnings per share.

5. Accounts Receivable, net

Accounts receivable consisted of the following (in thousands):

Allowance for credit losses	(2,609)		(3,566)
Accounts receivable, net	$	169,948	$	154,673

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

◦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 is required 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 is required to maintain a Fixed Charge Coverage Ratio of 1.25 to 1.0 for the duration of the Credit Agreement, as defined in the Credit Agreement.

•The Credit Agreement limits the Company’s ability to, among other things, create liens, make investments, incur more indebtedness, merge or consolidate, make dispositions of property, pay dividends, make distributions to stockholders or repurchase our stock, enter into a new line of business, enter into transactions with affiliates and enter into burdensome agreements.

•The Credit Agreement does not limit the Company’s ability to acquire other businesses or companies except that the acquired business or company must be in the Company's line of business, the Company must be in compliance with the financial covenants on a pro forma basis after taking into account the acquisition, and the Company must provide written notice at least five business days prior to the date of an acquisition of $10 million or more.

•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.

On August 5, 2026, the Company entered into the Amendment to its Credit Agreement dated August 1, 2022, with the lenders party thereto and JPMorgan Chase Bank, N.A., as administrative agent. The Amendment extended the maturity date of the Company’s $190.0 million revolving credit facility and approximately $87.3 million outstanding term loan under the Credit Agreement from July 30, 2027 to July 28, 2028.

In connection with the Amendment, the Company incurred an extension fee equal to a total of 0.15% of the aggregate committed amount of the revolving credit facility and term loan held by participating lenders. There were no other changes to the material terms of the Credit Agreement, including the applicable interest rate provisions and financial covenants, which remained substantially unchanged.

As of September 30, 2026, the Company had borrowings of $172.3 million (consisting of $85.0 million under the revolving credit facility and $87.3 million under the term loan, net of unamortized debt issuance costs) and a total of $3.3 million of letters of credit outstanding under the Credit Agreement. The Company has capitalized costs associated with debt modifications of $0.6 million as of September 30, 2026, which are included in Other assets on the Unaudited Condensed Consolidated Balance Sheets and will be amortized into interest expense over the remaining term of the Credit Agreement through its maturity date.

As of September 30, 2026, 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 September 30, 2026, there was an aggregate of approximately $1.5 million outstanding, payable at various times through 2030.

12. 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 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.

13. Commitments and Contingencies

Legal Proceedings and Government Investigations

The Company is periodically involved in lawsuits, investigations and claims. While uncertainties exist with respect to the ultimate resolution of lawsuits, investigations and claims asserted against it, except as stated below, the Company, based on currently available information, does not believe that any currently pending or threatened legal proceeding to which the Company is a party, or is likely to become a party, will have a material adverse effect on its business, results of operations, cash flows or financial condition. The costs incurred by the Company to defend lawsuits, investigations and claims and amounts the Company pays to other parties because of these matters may be covered by insurance in some circumstances.

Litigation and Commercial Claims

The Company and a subsidiary of the Company, Mistras Arizona Inspection Services LLC (“Mistras Arizona”), are subject to a lawsuit (the "DEQ Proceeding") filed by the State of Arizona and the Arizona Department of Environmental Quality (collectively, “DEQ”). The DEQ Proceeding, captioned State of Arizona v. Mistras Group, Inc., Mistras Arizona Inspection Services, LLC and Naiman Phoenix, Ltd., was originally filed on February 27, 2024, in the Superior Court of the State of Arizona for Maricopa County, CV 2024-003866 (the "DEQ Complaint"). The DEQ Complaint alleges various violations of Arizona environmental laws and regulations by Mistras Arizona in connection with the operation by Mistras Arizona of its testing facility in Phoenix, Arizona. The DEQ Complaint seeks, through injunctive relief, the closing of a chromic acid plating line at the testing facility, implementation of a site assessment plan approved by DEQ, and corrective and remedial action to bring the testing facility into compliance with laws and regulations. In addition, DEQ is seeking unspecified penalties and costs in connection with the DEQ Proceeding.

The Superior Court held a hearing in September 2024 regarding the DEQ’s request for a preliminary injunction. On October 23, 2024, the Superior Court issued a ruling, which declined to issue the preliminary injunction requested by the DEQ, but imposed the following conditions on the Company and Mistras Arizona unless and until modified by the Superior Court or entry of a final judgment: (1) the Company and Mistras Arizona are prohibited from releasing or permitting any release of chromic acid from the facility; (2) within a reasonable time, the Company and Mistras Arizona must complete improvements to the testing facility designed to prevent future discharges of chromium or chromic acid; (3) the Company and Mistras Arizona must notify the DEQ upon completion of the improvement to enable the DEQ to conduct an inspection; and (4) the Company and Mistras Arizona are prohibited from engaging in any chrome plating operations at the testing facility until they notify the DEQ that the improvements have been completed. The DEQ may seek relief if it determines that the improvements are not sufficient to prevent discharges. In April 2025, Mistras Arizona notified the DEQ that the improvements were completed, which the DEQ

then inspected. Following the DEQ site visit, Mistras Arizona commenced its chrome plating operations on April 28, 2025. Mistras Arizona has been and intends to continue complying with the Superior Court's ruling. In the meantime, the DEQ Proceeding is ongoing.

It is probable that additional investigation and/or remediation costs, as well as fines and penalties will be imposed related to the DEQ Proceeding. However, the Company is unable to estimate the range of loss that it may incur and whether these amounts will be material to the Company.

In addition, Mistras Arizona’s operations in Phoenix are located at a leased site within the footprint of the Motorola 52nd Street Superfund Site (the “Motorola Site”). Mistras Arizona has received two General Notice Letters from the U.S. Environmental Protection Agency (the "EPA"), dated May 21, 2024 and December 1, 2025, informing Mistras Arizona that the EPA has identified it as a potentially responsible party in relation to the Motorola Site. On April 29, 2025, the Company received a notice from the EPA requesting information regarding the improvements and other matters related to the Phoenix testing facility. Mistras Arizona provided the EPA with the requested information in July 2025.

Pension Related Contingencies

Certain of the Company’s subsidiaries had significant reductions in their unionized workers in 2018. The collective bargaining agreements for the employees of these subsidiaries required contributions for these employees to two national multi-employer pension funds. The reduction in employees resulted in one of the Company's subsidiaries incurring a complete withdrawal to one of the pension funds under the Employee Retirement Income Security Act of 1974 ("ERISA"), which was fully satisfied in 2019. The Company has determined that the subsidiary is likely to incur partial or complete withdrawal liability to the other pension fund. The balance of the estimated total amount of this potential liability as of September 30, 2026 is approximately $2.1 million, which was incurred in 2018 and 2019.

14. Segment Disclosure

The Company’s three operating segments, which are also the Company's reportable segments, are:

industrial and public infrastructure and commercial aerospace components. Software, digital and data services are included in this segment.

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 chief operating decision maker ("CODM") reviews financial information at the operating segment level to allocate resources and to assess the operating results and financial performance for each operating segment. The Company's CODM is Natalia Shuman, our Chief Executive Officer, as she has final authority over performance assessment and resource allocation decisions. Our segments are based on the type and concentration of customers served, service requirements, methods of distribution and major product lines.

Segment income (loss) from operations is the primary performance measure used by the CODM to evaluate segment performance and allocate resources, including considering budget-to-actual variances and prior year-to-actual variances on a monthly basis in accordance with GAAP under ASC 280, Segment Reporting. Segment income (loss) from operations for each of the Company's reportable segments are comprised of revenue, selling, general & administrative expenses, and "other expenses." "Other expenses" include cost of revenue, reorganization and environmental costs, transaction-related expense, depreciation and amortization and research and engineering.

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. These items of our operating profit are managed centrally at the corporate level and are excluded from the measure of segment income reviewed by the CODM, as well as the measure of segment performance used for incentive compensation purposes.

The accounting policies of the reportable segments are the same as those described in Note 1 - Description of Business and Basis of Presentation.

Selected consolidated financial information by segment for the periods shown was as follows. Income (loss) from operations by operating segment includes intercompany transactions, which are eliminated in Corporate and eliminations.

Forward-Looking Statements

This Quarterly Report contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), including statements regarding the anticipated timing and completion of the Merger, the anticipated benefits of the Merger, the consideration to be received by the Company’s stockholders in connection with the Merger, and other statements about the future plans, objectives, expectations and intentions of the Company. Such forward-looking statements include those that express plans, anticipation, intent, contingency, goals, targets or future development and/or otherwise are not statements of historical fact. These forward-looking statements are based on our current expectations and projections about future events and they are subject to risks and uncertainties known and unknown that could cause actual results and developments to differ materially from those expressed or implied in such statements.

In some cases, you can identify forward-looking statements by terminology, such as “goals,” or “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “may,” “could,” “should,” “would,” “predicts,” “appears,” “projects,” or the negative of such terms or other similar expressions. Forward-looking statements are inherently subject to risks and uncertainties, many of which are beyond the Company’s control. These risks and uncertainties include, but are not limited to, the following: (i) the ability to complete the Merger on the anticipated timeline, or at all; (ii) the satisfaction or waiver of the conditions to the completion of the Merger, including the approval by the Company’s stockholders and receipt of the required regulatory approvals; (iii) the receipt of required regulatory approvals on the terms anticipated or at all, or the imposition of conditions on such approvals that could reduce the anticipated benefits of the Merger or cause the parties to abandon the Merger; (iv) the Merger may involve unexpected costs, liabilities or delays, including the payment of the Company Termination Fee (as defined herein) to Parent by the Company; (v) the Company may be adversely affected by other economic, business, legislative, regulatory and/or competitive factors; (vi) the outcome of any stockholder demands or legal proceedings that have been or may be instituted against the Company and others relating to the Merger Agreement or the Merger; (vii) the occurrence of any event, change or other circumstance that could give rise to the termination of the Merger Agreement; (viii) potential disruption to the business of the Company as a result of the announcement and pendency of the Merger; (ix) the diversion of management attention from the Company’s ongoing business operations as a result of the Merger; (x) adverse effects on the Company’s ability to retain and hire key personnel as a result of the announcement or pendency of the Merger; (xi) volatility in the Company’s stock price prior to the completion of the Merger; (xii) changes or developments in the industries in which the Company competes, general economic conditions, or conditions in the financial markets or capital markets; (xiii) any impacts from the imposition of tariffs or other trade restrictions and changes to U.S. trade policy, including the outcome of pending litigation regarding tariffs and the availability of refunds of tariffs previously imposed under the International Emergency Economic Powers Act; (xiv) impacts and uncertainty arising from geopolitical instability and conflicts, including those related to the conflict involving the U.S. and Iran and the war in Ukraine, and resulting volatility in oil and natural gas prices and in capital spending and maintenance activity by our oil and gas customers; (xv) the creditworthiness of our customers and our ability to collect our accounts receivable; (xvi) changes in interest rates and foreign currency exchange rates; and (xvii) other risks and uncertainties described in the Company’s filings with the Securities and Exchange Commission (the “SEC”), including those discussed in the “Business—Forward-Looking Statements,” and “Risk Factors” sections of our 2025 Annual Report as well as those discussed in this Quarterly Report. 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. 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 global leader in technology-enabled industrial asset integrity solutions, serving critical industries including oil & gas, aerospace & defense, power & utilities, manufacturing, and civil infrastructure.

The Company’s core capabilities also include NDT field inspections enhanced by advanced robotics, laboratory quality control and assurance testing, sensing technologies and NDT equipment, asset and mechanical integrity engineering services, and light mechanical maintenance and access services.

Our operations consist of three reportable segments: North America, International, and Products and Systems.

•North America provides asset protection solutions predominantly in North America, with the largest concentration in the United States, followed by Canada, consisting primarily of NDT, inspection, mechanical and engineering services that are used to evaluate the 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 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 oil and gas, aerospace and defense, industrials, power generation and transmission (including alternative and renewable energy), infrastructure, research and engineering, petrochemical, and other process 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 the past 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 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 spending to be impacted by fluctuations in oil prices and broader market conditions, including potential geopolitical disruptions and uncertainty arising from conflicts in the Middle East.

We have continued providing our customers with an innovative asset protection software ecosystem through our OneSuite platform. The software platform offers functions of our software and services brands as integrated apps on a cloud environment. OneSuite serves as a single access portal for customers' data activities and provides access to 90 plus applications being offered on one centralized platform.

Recent Developments

Our cash position and liquidity remain strong. As of September 30, 2026, our cash and cash equivalents balance was approximately $19.0 million, and we had available borrowing capacity of up to $101.7 million under the revolving credit facility under our Credit Agreement.

The Merger is expected to close in late 2026 or early 2027, subject to, among other things, approval of the Merger by the Company’s stockholders, expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), the receipt of certain required regulatory approvals, and the satisfaction or waiver of certain other customary closing conditions. Effective October 22, 2026, the Federal Trade Commission granted early termination of the HSR Act waiting period. If the Merger is completed, the Company’s common stock will be delisted from the New York Stock Exchange (the “NYSE”) and deregistered under the Exchange Act.

On August 5, 2026, the Company entered into an amendment (the "Amendment") to its credit agreement dated August 1, 2022 (as amended, the "Credit Agreement"), with the lenders party thereto and JPMorgan Chase Bank, N.A., as administrative agent. The Amendment extended the maturity date of the Company’s $190.0 million revolving credit facility and approximately $87.3 million outstanding term loan under the Credit Agreement from July 30, 2027 to July 28, 2028. In connection with the Amendment, the Company incurred an extension fee equal to a total of 0.15% of the aggregate committed amount of the revolving credit facility and term loan held by participating lenders. There were no other changes to the material terms of the Credit Agreement, including the applicable interest rate provisions and financial covenants, which remained substantially unchanged. Refer to Note 11 - Long-Term Debt for more details regarding the terms of the Credit Agreement.

to begin processing refunds of previously collected IEEPA tariffs, and CBP has since processed refund claims in phases, most recently commencing in October 2026 the processing of refunds for certain finally liquidated entries. In October 2026, the U.S. Court of International Trade also certified a class of importers seeking IEEPA tariff refunds and the U.S. government’s appeals in the refund litigation remain pending. In response to the U.S. Supreme Court's ruling, the U.S. administration implemented replacement tariffs under alternative statutory authorities, including a temporary tariff under Section 122 of the Trade Act of 1974, which expired on July 24, 2026 at the end of its 150-day statutory period. The U.S. Court of International Trade ruled against the Section 122 tariffs, but that ruling has been stayed pending appeal, and the related litigation remains ongoing. Effective July 24, 2026, the U.S. administration implemented additional tariffs ranging from 10% to 12.5% on imports from numerous trading partners under Section 301 of the Trade Act of 1974, which are also subject to legal challenge. Accordingly, the ultimate scope, duration and financial impact of U.S. trade measures remain uncertain. Ongoing changes to trade policies and related uncertainty may affect global economic conditions, supply chains and costs, and may reduce trade between the U.S. and impacted countries. Tariffs and trade barriers have not had a material effect on our business or results of operations during 2026 to date. However, new tariffs or other trade measures could result in increased costs for us or our suppliers and could impact the import of materials by our customers, including materials subject to our inspection and testing services, which could adversely affect demand for our services.

Note About Non-GAAP Measures

The Company prepares its consolidated financial statements in accordance with GAAP. In this MD&A under the heading "Income from Operations", the non-GAAP financial performance measure "Income from operations before special items” is used for each of our three operating segments, “Corporate and Eliminations” and the "Total Company", with tables reconciling the measure to a financial measure under GAAP. This presentation excludes from "Income from Operations" (a) reorganization and other costs, which includes items such as severance, labor relations matters and asset and lease termination costs, (b) transaction-related expense, which are expenses that consist of legal, financial advisory and other professional fees incurred in connection with the Merger Agreement and beginning in the three months ended September 30, 2026, is excluded from this measure, and (c) environmental expense, which relates to costs associated with the environmental matter at the Phoenix lab operated by Mistras Arizona, as described in Note 13 to the Unaudited Condensed Consolidated Financial Statements in this Quarterly Report. 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. Our management uses this non-GAAP measure as a measure of operating performance 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 from operations 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 from operations before special items is not used to determine incentive compensation for executives or employees, nor is it a replacement for the reported GAAP financial performance and/or necessarily comparable to the non-GAAP financial measures of other companies. Any measure that eliminates the foregoing items has material limitations as a performance measure and should not be considered an alternative to net income or any other measures derived in accordance with GAAP. Because Income from operations before special items may not be calculated in the same manner by all companies, this measure may not be comparable to other similarly titled measures used by other companies.

In this MD&A under the heading “Adjusted EBITDA,” we also present the non-GAAP financial measures “Adjusted EBITDA” and “Adjusted EBITDA Margin.” We define Adjusted EBITDA as net income (loss) attributable to Mistras Group, Inc. plus: interest expense, provision (benefit) for income taxes, depreciation and amortization, share-based compensation expense, reorganization and other related costs, transaction-related expense, environmental expense, net, foreign exchange (gain) loss

and, if applicable, certain acquisition-related costs, non-cash impairment charges and other special items, which are noted. Adjusted EBITDA Margin is Adjusted EBITDA divided by revenue. The most directly comparable GAAP measures are net income (loss) attributable to Mistras Group, Inc. and net income (loss) attributable to Mistras Group, Inc. as a percentage of revenue, which were 3.4% and 6.7% for the three months ended September 30, 2026 and 2025, respectively, and 3.0% and 2.4% for the nine months ended September 30, 2026 and 2025, respectively. Adjusted EBITDA is also a performance metric used to determine incentive compensation for our executive officers, as described in Note 3 - Share-Based Compensation; for that purpose it may be subject to adjustments approved by the Compensation Committee. Adjusted EBITDA has material limitations as an analytical tool because it excludes charges and expenses we incur as part of our operations, and it should not be considered in isolation or as a substitute for net income or other measures derived in accordance with GAAP. Adjusted EBITDA may not be comparable to similarly titled measures used by other companies.

Interest Expense

Interest expense was flat at approximately $3.4 million for both the three months ended September 30, 2026 and 2025. Interest expense was approximately $10.5 million and $10.9 million for the nine months ended September 30, 2026 and 2025, respectively. This decrease of $0.4 million in interest expense was a result of lower interest rates and lower average borrowings outstanding during the nine months ended September 30, 2026 in comparison to the prior year comparable period.

Income Taxes

Our effective income tax rate was approximately 37.7% and 22.3% for the three months ended September 30, 2026 and 2025, respectively. Our effective income tax rate was approximately 28.8% and 21.9% for the nine months ended September 30, 2026 and 2025, respectively.

The effective income tax rate for the three months ended September 30, 2026, was higher than the statutory rate primarily due to non-deductible transaction costs. The effective income tax rate for the three months ended September 30, 2025 was higher than the statutory rate primarily due to the impact of foreign currency losses.

The effective income tax rate for the nine months ended September 30, 2026, was higher than the statutory rate primarily due to non-deductible transaction costs. The effective income tax rate for the nine months ended September 30, 2025, was higher than the statutory rate primarily due to the impact of foreign currency losses.

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.

Cash Flows from Operating Activities

During the nine months ended September 30, 2026, cash provided by operating activities was $29.4 million, representing a year-over-year increase of $28.6 million, or 3,392%. This increase was primarily attributable to an increase in net income and movements in working capital, primarily due to higher collections of accounts receivable as compared to the prior year comparable period.

Cash Flows from Investing Activities

During the nine months ended September 30, 2026, cash used in investing activities was $25.0 million, representing a $6.0 million increase compared to the prior year comparable period. The increase is primarily attributable to increased expenditures for property, plant, and equipment and intangible assets.

Cash Flows from Financing Activities

Net cash used in financing activities was $12.3 million for the nine months ended September 30, 2026, compared to net cash provided by financing activities of $26.2 million for the nine months ended September 30, 2025. During the nine months ended September 30, 2026, net payments of debt were approximately $10.0 million compared to net borrowings of debt of $27.7 million in the prior year comparable period.

Effect of Exchange Rate Changes on Cash and Cash Equivalents

The effect of exchange rate changes on our cash and cash equivalents was a decrease of $1.2 million in the nine months ended September 30, 2026, compared to an increase of $1.4 million for the nine months ended September 30, 2025.

Cash Balance and Credit Facility Borrowings

As of September 30, 2026, we had cash and cash equivalents totaling $19.0 million and $101.7 million of unused commitments under our Credit Agreement with borrowings of $172.3 million (consisting of $85.0 million under the revolving credit facility and $87.3 million under the term loan, net of unamortized debt issuance costs) and $3.3 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 September 30, 2026, 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 Company believes that it is probable that the Company will be able to comply with the financial covenants in the Credit Agreement and that sufficient credit remains available under the Credit Agreement to meet the Company's liquidity needs. However, such matters cannot be predicted with certainty.

The terms of our Credit Agreement are described in Note 11 - Long-Term Debt of the Notes to the Unaudited Condensed Consolidated Financial Statements, under the heading "Senior Credit Facility".

Risks Related to the Pending Merger

On September 17, 2026, the Company entered into the Merger Agreement with Parent and Acquisition Sub, pursuant to which, subject to the terms and conditions of the Merger Agreement, Acquisition Sub will be merged with and into the Company, with the Company surviving the Merger as a wholly owned subsidiary of Parent. Parent and Acquisition Sub are controlled by funds affiliated with H.I.G. At the Effective Time, each outstanding share of our common stock (other than certain excluded and dissenting shares) will be converted into the right to receive $20.35 in cash, without interest and less applicable withholding taxes. See Note 1 – Description of Business and Basis of Presentation to the Unaudited Condensed Consolidated Financial Statements for additional information.

The Merger may not be completed on the anticipated timeline or at all, and failure to complete the Merger could adversely affect our business, financial condition, results of operations and stock price.

Completion of the Merger is subject to the satisfaction or, where permitted, waiver of a number of conditions, including (i) the adoption of the Merger Agreement by the Company’s stockholders; (ii) the expiration or termination of the applicable waiting period under the HSR Act (which was terminated effective October 22, 2026) and the expiration or termination of applicable waiting periods, or receipt of applicable approvals, under specified non-U.S. competition laws; (iii) the completion of required regulatory actions relating to our U.S. Nuclear Regulatory Commission and Agreement State licenses; (iv) the absence of any law or order prohibiting the consummation of the Merger; and (v) other customary conditions, including the accuracy of our representations and warranties (subject to specified materiality standards), our compliance in all material respects with our covenants and the absence of a Company Material Adverse Effect (as defined in the Merger Agreement). Any such required consents and approvals may not be received at all, may not be received in a timely fashion, or may impose conditions on the completion of the Merger. We cannot assure you that all of the conditions in the Merger Agreement will be satisfied or waived on a timely basis or at all. If the conditions in the Merger Agreement are not satisfied or waived on a timely basis or at all, we may be unable to complete the Merger in the timeframe or manner currently anticipated or at all.

If the Merger is not completed for any reason, our stockholders will not receive any payment for their shares in connection with the Merger, and we will remain a public company subject to the same risks to which we are currently subject. In addition, we may be subject to a number of risks, including the following:

•the market price of our securities could decline to the extent that the current market price reflects an assumption that the Merger will be completed;

•commitments by management of time and resources to the Merger could prevent management from pursuing other opportunities that could otherwise have been beneficial for the Company;

•we may experience negative reactions from the financial markets or from our clients, business partners or employees;

•our business may be disrupted by the announcement and pendency of the Merger, including adverse changes in our relationships with clients, suppliers, partners and employees that may continue or intensify in the event the Merger is not consummated or is significantly delayed;

•we may be unable to attract and retain key personnel and recruit prospective employees, and our current employees could be distracted, and their productivity decline as a result, due to uncertainty regarding the Merger;

Table of Contents

•we may be unable to pursue alternative business opportunities, make changes to our business pending the completion of the Merger or conduct our business on the same terms as we have in the past; and

•we have incurred, and expect to continue incurring, significant costs, expenses, and fees for professional services and other Merger-related costs, for which we may receive little or no benefit if the Merger is not completed, and many of these fees and costs will be payable by us even if the Merger is not completed.

The Merger Agreement contains restrictions on the conduct of our business prior to the completion of the Merger, which could adversely affect our business and operations.

The Merger Agreement generally requires us to conduct our business in the ordinary course consistent with past practice and, subject to specified exceptions or Parent’s prior written consent (not to be unreasonably withheld, conditioned or delayed), restricts us from taking certain actions until the earlier of the completion of the Merger and the termination of the Merger Agreement. Among other things, these restrictions limit our ability to make capital expenditures in excess of an agreed budget and specified thresholds, acquire or dispose of businesses or assets above specified thresholds, incur indebtedness, pay dividends or repurchase stock, enter into or amend material contracts, enter into a new line of business, and increase compensation or benefits or hire or terminate certain employees. These restrictions may prevent us from pursuing business opportunities that arise prior to the completion of the Merger, from responding effectively to competitive pressures or industry developments, or from taking other actions that we might otherwise consider to be in our best interests, and could adversely affect our business, financial condition and results of operations, particularly if the Merger is delayed or not completed.

We will incur substantial transaction costs in connection with the Merger, and we may be required to pay Parent a termination fee or reimburse Parent’s expenses if the Merger Agreement is terminated under specified circumstances.

We have incurred and expect to continue to incur significant costs, expenses and fees for professional services and other transaction costs in connection with the Merger, including the costs of the go-shop process and of obtaining required regulatory approvals, substantially all of which are payable whether or not the Merger is completed. In addition, if the Merger Agreement is terminated under specified circumstances, we could be required to pay Parent a termination fee of approximately $27.5 million (the “Company Termination Fee”). Had we terminated the Merger Agreement during the go-shop period, which expired on October 27, 2026, to enter into a definitive agreement providing for a superior proposal, the fee would have been reduced to approximately $13.8 million. In addition, if Parent terminates the Merger Agreement as a result of our willful and material breach, we could be required to reimburse Parent’s reasonable and documented out-of-pocket expenses up to $7.0 million, which amount would be credited against any Company Termination Fee subsequently payable. Payment of these amounts could require us to use available cash that would otherwise have been available for operations or other purposes and could adversely affect our financial condition, results of operations and cash flows.

The Merger Agreement limits our ability to pursue alternatives to the Merger, which may discourage other companies from making a favorable alternative transaction proposal.

The Merger Agreement permitted us to solicit alternative acquisition proposals during a go-shop period that expired at 11:59 p.m. Eastern Time on October 27, 2026. During the go-shop period, our financial advisor contacted, or was contacted by, 122 third parties, and no alternative acquisition proposals were received.

The Merger Agreement contains provisions that, subject to certain exceptions, limit our ability to solicit, initiate, knowingly encourage or facilitate, or engage in discussions or negotiations with respect to, alternative third-party acquisition proposals. These provisions or other provisions in the Merger Agreement could discourage a potential competing acquiror that might have an interest in acquiring all or a significant portion of the Company or pursuing an alternative transaction from considering or proposing such a transaction.

Legal proceedings against the Company relating to the Merger could result in substantial costs or otherwise negatively impact our business, operating results and financial condition.

On October 15, 2026 and October 23, 2026, the Company received two letters from counsel for purported stockholders of the Company demanding, pursuant to Section 220 of the Delaware General Corporation Law, inspection of certain of our books and records relating to the Merger. The letters state that the stockholders may file suit or pursue other legal relief relating to the Merger. The Company has also received demand letters from certain purported stockholders of the Company seeking additional disclosure in advance of the stockholder vote. Additional demands may be made, and litigation relating to the Merger may be filed, against the Company, Parent, their respective affiliates and/or their respective boards of directors and management. The outcome of any litigation is uncertain and any such lawsuits could prevent or delay the completion of the Merger and result in

Table of Contents

significant costs. The litigation costs, including costs associated with our indemnification obligations to our directors and officers, and diversion of management’s attention and resources to address the claims in any litigation related to the Merger, may adversely affect our business, results of operations, prospects, and financial condition. In addition, any litigation related to the Merger may result in negative publicity or an unfavorable impression of the Company, which could adversely affect the price of our common stock, impair our ability to recruit or retain employees, damage our relationships with our clients and business partners, or otherwise harm our operations and financial performance.

Uncertainties associated with the Merger may cause a loss of our employees during the pendency of the Merger.

No assurance can be given that we will be able to retain key employees to the same extent that we have been able to in the past. The Company may lose significant expertise and talent, and the loss of any member of the senior management team could impair the Company’s ability to execute its business plan and growth strategy. Our current and prospective employees may experience uncertainty about their future roles following the Merger, which may materially adversely affect our ability to attract, retain, and motivate key personnel during the pendency of the Merger. Our employees could lose productivity as a result of uncertainty regarding their employment following the Merger. The loss of key personnel during the pendency of the Merger could adversely affect our business and operations.

If the Merger is completed, our stockholders will forgo the opportunity to benefit from potential future appreciation in value of the Company.

The Merger Agreement provides for the stockholders of record of our common stock to receive cash consideration of $20.35 per share of our common stock, without interest, upon the closing of the transactions contemplated by the Merger Agreement. If the Merger is completed, our stockholders will no longer hold interests in the Company and will not participate in any future earnings or growth of the Company or benefit from any appreciation in its value.
