1. Description of Business and Basis of Presentation

Description of Business

Mistras Group, Inc. and subsidiaries (the Company) is a leading “one source” global provider of technology-enabled asset protection solutions used to evaluate the structural integrity and reliability of critical energy, industrial and public infrastructure. The Company combines industry-leading products and technologies, expertise in mechanical integrity (MI) and non-destructive testing (NDT) services and proprietary data analysis software to deliver a comprehensive portfolio of customized solutions, ranging from routine inspections to complex, plant-wide asset integrity assessments and management. These mission critical solutions enhance customers’ ability to extend the useful life of their assets, increase productivity, minimize repair costs, comply with governmental safety and environmental regulations, manage risk and avoid catastrophic disasters. The Company serves a global customer base of companies with asset-intensive infrastructure, including companies in the oil and gas, fossil and nuclear power, alternative and renewable energy, public infrastructure, chemicals, commercial aerospace and defense, transportation, primary metals and metalworking, pharmaceutical/biotechnology and food processing industries and research and engineering institutions.

Basis of Presentation

The condensed consolidated financial statements contained in this report are unaudited. In the opinion of management, the 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 fiscal years ending May 31, 2015 and 2014 . Reference to a fiscal year means the fiscal year ended May 31 . 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 consolidated financial statements contained in the Company’s Annual Report on Form 10-K (“Annual Report”) for fiscal 2014 , as filed with the Securities and Exchange Commission on August 8, 2014 .

Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of Mistras Group, Inc. and its wholly and majority-owned subsidiaries. For subsidiaries in which the Company’s ownership interest is less than 100%, the noncontrolling interests are reported in stockholders’ equity in the accompanying consolidated balance sheets. The noncontrolling interests in net income, net of tax, is classified separately in the accompanying consolidated statements of income.

All significant intercompany accounts and transactions have been eliminated in consolidation. Mistras Group, Inc.’s and its subsidiaries’ fiscal years end on May 31 except for the subsidiaries in the International segment, which end on April 30. Accordingly, the Company’s International segment subsidiaries are consolidated on a one month lag. Therefore, in the quarter and year of acquisition, results of acquired subsidiaries in the International segment are generally included in consolidated results for one less month than the actual number of months from the acquisition date to the end of the reporting period. Management does not believe that any events occurred during the one-month lag period that would have a material effect on the Company’s consolidated financial statements.

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 2 — Summary of Significant Accounting Policies in the Company's Annual Report. On an ongoing basis, we evaluate its estimates and assumptions, including, among other things those related to revenue recognition, valuations of accounts receivable, long-lived assets, goodwill, deferred tax assets and uncertain tax positions. Since the date of the 2014 Annual Report, there have been no material changes to the Company's significant accounting policies.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers , which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2016. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company is currently evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures.

In June 2014, the FASB issued ASU 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved After the Requisite Service Period . This ASU requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. ASU 2014-12 is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2015. The Company is currently evaluating the effect that ASU 2014-12 will have on its consolidated financial statements and related disclosures.

In February 2015, the Financial Accounting Standards Board issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidations Analysis , which changes the guidance for evaluating whether to consolidate certain legal entities. Specifically, the amendments modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities ("VIEs") or voting interest entities. Further, the amendments eliminate the presumption that a general partner should consolidate a limited partnership, as well as affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships. The updated guidance is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2015. Early adoption is permitted. Companies have an option of using either a full retrospective or modified retrospective adoption approach. The Company is evaluating the effect that ASU 2015-02 will have on its consolidated financial statements and related disclosures.

2. Share-Based Compensation

The Company has share-based incentive awards outstanding to its eligible employees and Directors under two employee equity incentive plans: (i) the 2007 Stock Option Plan (the 2007 Plan), and (ii) the 2009 Long-Term Incentive Plan (the 2009 Plan). No further awards may be granted under the 2007 Plan, although awards granted under the 2007 Plan remain outstanding in accordance with their terms. Awards granted under the 2009 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.

Stock Options

For the three months ended February 28, 2015 and 2014 , the Company recognized share-based compensation expense related to stock option awards of less than $0.1 million for each period respectively. For the nine months ended February 28, 2015 and 2014 , the Company recognized share-based compensation expense related to stock option awards of less than $0.1 million and $0.7 million respectively. As of February 28, 2015 , there was less than $0.1 million of unrecognized compensation costs, net of estimated forfeitures, related to stock option awards, which are expected to be recognized over a remaining weighted average period of 1.0 year .

No stock options were granted during the nine months ended February 28, 2015 and 2014 .

Restricted Stock Unit Awards

For the three months ended February 28, 2015 and 2014 , the Company recognized share-based compensation expense related to restricted stock unit awards of $1.2 million and $1.0 million , respectively. For the nine months ended February 28, 2015 and 2014 , the Company recognized share-based compensation expense related to restricted stock unit awards of $3.5 million and $2.9 million , respectively. As of February 28, 2015 , there was $9.0 million of unrecognized compensation costs, net of

(tabular dollars in thousands, except per share data)

estimated forfeitures, related to restricted stock unit awards, which are expected to be recognized over a remaining weighted average period of 2.4 years .

During the first nine months of fiscal 2015 and 2014 , the Company granted approximately 21,000 and 19,000 shares, respectively, of fully-vested common stock to its five non-employee directors, in connection with its non-employee director compensation plan. These shares had grant date fair values of $0.4 million for each period respectively, which was recorded as share-based compensation expense during the nine months ended February 28, 2015 and 2014 .

During the first nine months of fiscal 2015 and 2014 , approximately 231,000 and 178,000 restricted stock units, respectively, vested. The fair value of these units was $5.2 million and $3.3 million , respectively. Upon vesting, restricted stock units are generally net share-settled to cover the required minimum withholding tax and the remaining amount is converted into an equivalent number of shares of common stock.

Performance Restricted Stock Units

In the second quarter of fiscal 2015 , the Company granted performance restricted stock units to its executive and certain other senior officers. These units have requisite service (vesting) periods of three years and have no dividend rights. For the three and nine months ended February 28, 2015 , the Company recognized share-based compensation expense related to performance restricted stock units of $0.1 million and $0.2 million , respectively. At February 28, 2015 , there was $1.6 million of total unrecognized compensation costs related to approximately 115,000 non-vested performance restricted stock units. These costs are expected to be recognized over a weighted-average period of approximately 2.5 years . The actual payout of these units will vary based on the Company’s performance over a three -year period (based on pre-established targets) and a market condition modifier based on total shareholder return (TSR) compared to an industry peer group. Compensation cost is initially measured assuming that the target performance condition will be achieved. However, compensation cost related to the performance condition is adjusted for subsequent changes in the expected outcome of the performance condition. Compensation cost related to the TSR condition is fixed at the measurement date, and not subsequently adjusted.

In the second quarter of fiscal 2014 , the Company granted performance restricted stock units to its executive officers and certain other senior officers. These units have requisite service (vesting) periods of three years and have no dividend rights. For the three months ended February 28, 2015 and 2014 , the Company recognized share-based compensation expense/(benefit) related to performance restricted stock units of $(0.9) million and less than $0.1 million , respectively. For the nine months ended February 28, 2015 and 2014 , the Company recognized share-based compensation expense related to performance restricted stock units of $0.7 million and $1.2 million , respectively. At February 28, 2015 , there was $2.5 million of total unrecognized compensation costs related to approximately 423,000 non-vested performance restricted stock units. These costs are expected to be recognized over a weighted-average period of approximately 1.5 years . The actual payout of these units will vary based on the Company’s performance over one , two and three -year periods (based on pre-established targets) and a market condition modifier based on TSR compared to an industry peer group. Compensation cost is initially measured assuming that the target performance condition will be achieved. However, compensation cost related to the performance condition is adjusted for subsequent changes in the expected outcome of the performance condition. Compensation cost related to the TSR condition is fixed at the measurement date, and not subsequently adjusted. The one -year performance condition of the fiscal 2014 awards was not achieved. The one -year market condition of the fiscal 2014 awards was achieved and will payout at 170% of target once the requisite service period is complete.

3. 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 reflects: (i) only 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 earnings per share:

4. Acquisitions

In the first nine months of fiscal 2015 , the Company completed four acquisitions. The Company purchased a company, located in Louisiana, a provider of maintenance and inspection services primarily on offshore platforms. This acquisition expands the service offerings within the Services segment, allowing the Company to provide services to the upstream operations of its customers. The Company also purchased a group of asset protection businesses located in Quebec, Canada and an asset inspection business in Florida to complement service offerings within the Company’s Services segment and continue its market expansion strategy. The Company’s International Segment completed an acquisition of an asset inspection business located in the United Kingdom.

In these acquisitions, the Company acquired 100% of the common stock or certain assets of each acquiree in exchange for aggregate consideration of approximately $35.7 million in cash and $20.5 million in notes payable issued as part of the acquisition and other liabilities assumed. The Company accounted for these transactions in accordance with the acquisition method of accounting for business combinations. In addition, the acquisitions in Quebec and Florida provide for contingent consideration of up to $3.2 million to be earned based upon the acquired business achieving specific performance metrics over the next three years of operation. The Company is in the process of completing the purchase price allocations for these acquisitions.

The amortization period of intangible assets acquired in fiscal 2015 ranges from 3 to 10 years. The Company recorded $45.2 million of goodwill in connection with these acquisitions, reflecting the strategic fit and revenue and earnings growth potential of these business.

Revenues and operating income from these acquisitions for the period subsequent to the closing of these transactions were $38.4 million and $2.0 million , respectively, for the nine month period ended February 28, 2015 . No unaudited pro forma financial information is required as these acquisitions are not significant to the Company.

In the first nine months of fiscal 2014, the Company completed four acquisitions. The Company acquired a professional engineering consulting and technical training services company located in the U.S. serving the hydrocarbon processing and other energy-related industries. The Company also completed the acquisition of an asset protection business located in Texas and two businesses located in Canada to continue its market expansion strategy. These companies were acquired to complement service offerings within the Company’s Services segment and expand its technical capabilities. In these acquisitions, the Company acquired 100% of the common stock or certain assets of each acquiree in exchange for aggregate consideration of $19.3 million in cash. In addition to the initial cash payment, the Company may pay up to $5.7 million in contingent consideration which may be earned based upon

(tabular dollars in thousands, except per share data)

the acquired companies achieving specific performance metrics over specified periods ranging from 2 to 3 years from the acquisition date.

The assets and liabilities of the businesses acquired in fiscal 2015 were included in the Company’s consolidated balance sheet based upon their estimated fair values on the date of acquisition as determined in a preliminary purchase price allocation, using available information and making assumptions management believes are reasonable. The Company is still in the process of completing its valuation of the assets, both tangible and intangible, and liabilities acquired. The results of operations for these acquisitions are included in each respective operating segment’s results of operations from the date of acquisition. For acquisitions in fiscal 2015 for which the final purchase accounting has yet to be completed, the Company’s preliminary purchase price allocations are included in the table below, summarizing the estimated fair value of the assets acquired and liabilities assumed at the date of acquisition:

	Fiscal
	2015
Number of Entities	3
Consideration transferred:
Cash paid	$ 34,529
Notes payable issued to seller	20,000
Contingent consideration	2,255
Consideration transferred	56,784
Current assets	9,684
Property, plant and equipment	6,964
Current deferred tax asset	652
Intangibles	12,373
Goodwill	44,272
Current liabilities	(12,800	)
Long-term deferred tax liability	(4,361	)
Net assets acquired	$ 56,784

During the nine month period ended February 28, 2015 , the Company incurred acquisition-related costs of $0.2 million , in connection with due diligence, professional fees, and other expenses related to its acquisition activity. Additionally, the Company adjusted the fair value of certain previously recorded acquisition-related contingent consideration liabilities. For the three and nine month periods ended February 28, 2015 , these adjustments resulted in a net decrease of acquisition-related contingent consideration liabilities and a corresponding increase in income from operations of $1.7 million and $3.3 million , respectively. The Company’s aggregate acquisition-related contingent consideration liabilities were $8.8 million and $14.1 million as of February 28, 2015 and May 31, 2014 , respectively.

During the three and nine month period ended February 28, 2014 , the Company incurred acquisition-related costs of $0.4 million and $0.9 million in connection with due diligence, professional fees, and other expenses for its acquisition activity. Additionally, the Company adjusted the fair value of certain acquisition-related contingent consideration liabilities. For the three month period ended February 28, 2014 , these adjustments resulted in a net increase of acquisition-related contingent consideration liabilities and a corresponding decrease in income from operations of $0.6 million . For the nine month period ended February 28, 2014 , these adjustments resulted in a net decrease of acquisition-related contingent consideration liabilities and a corresponding increase in income from operations of $2.4 million , respectively.

The fair value adjustments to acquisition-related contingent consideration liabilities and the acquisition-related transaction costs have been classified as acquisition-related expense, net in the condensed consolidated statements of income for the three and nine month periods ended February 28, 2015 and 2014 .

Senior Credit Facility

On October 31, 2014, the Company entered into a Third Amendment and Modification Agreement (the “Amendment”), to its revolving line of credit, the Third Amended and Restated Credit Agreement (“Credit Agreement”), dated December 21, 2011, with Bank of America, N.A., as agent for the lenders and a lender, and JPMorgan Chase Bank, N.A., Keybank, National Association and TD Bank, N.A., as lenders. The Amendment increased the Company’s revolving line of credit to from $125.0 million to $175.0 million and provides that under certain circumstances the line of credit can be increased to $225.0 million . The Company may continue to borrow up to $30.0 million in non-U.S. Dollar currencies and use up to $10.0 million of the credit limit for the issuance of letters of credit. The Amendment also extended the original maturity date of the Credit Agreement from December 20, 2016 to October 30, 2019. As of February 28, 2015 , the Company had borrowings of $96.7 million and a total of $4.7 million of letters of credit outstanding under the Credit Agreement.

Loans under the Credit Agreement bear interest at LIBOR plus an applicable LIBOR margin ranging from 1% to 1.75% , or a base rate less a margin of 1.25% to 0.375% , at the option of the Company, based upon the Company’s Funded Debt Leverage Ratio. Funded Debt Leverage Ratio is generally the ratio of (1) all outstanding indebtedness for borrowed money and other interest-bearing indebtedness as of the date of determination to (2) EBITDA (which is (a) net income, less (b) income (or plus loss) from discontinued operations and extraordinary items, plus (c) income tax expenses, plus (d) interest expense, plus (e) depreciation, depletion, and amortization (including non-cash loss on retirement of assets), plus (f) stock compensation expense, less (g) cash expense related to stock compensation, plus or minus certain other adjustments) for the period of four consecutive fiscal quarters immediately preceding the date of determination. The Company has the benefit of the lowest margin if its Funded Debt Leverage Ratio is equal to or less than 0.5 to 1, and the margin increases as the ratio increases, to the maximum margin if the ratio is greater than 2.0 to 1. The Company will also bear additional costs for market disruption, regulatory changes effecting the lenders’ funding costs, and default pricing of an additional 2% interest rate margin on any amounts not paid when due. Amounts borrowed under the Credit Agreement are secured by liens on substantially all of the assets of the Company.

Notes to Unaudited Condensed Consolidated Financial Statements

(tabular dollars in thousands, except per share data)

The Credit Agreement contains financial covenants requiring that the Company maintain a Funded Debt Leverage Ratio of no greater than 3.0 to 1 and an Interest Coverage Ratio of at least 3.0 to 1. Interest Coverage Ratio means the ratio, as of any date of determination, of (a) EBITDA for the 12 month period immediately preceding the date of determination, to (b) all interest, premium payments, debt discount, fees, charges and related expenses of the Company and its subsidiaries in connection with borrowed money (including capitalized interest) or in connection with the deferred purchase price of assets, in each case to the extent treated as interest in accordance with GAAP, paid during the 12 month period immediately preceding the date of determination. The Credit Agreement also 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 and make distributions to stockholders, 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, if the acquired business is a separate subsidiary, in certain circumstances the lenders will receive the benefit of a guaranty of the subsidiary and liens on its assets and a pledge of its stock.

As of February 28, 2015 , the Company was in compliance with the terms of the Credit Agreement, and will continuously monitor its compliance with the covenants contained in its credit agreement.

Notes Payable and Other

In connection with certain of its acquisitions through fiscal 2015 , the Company issued subordinated notes payable to the sellers. The maturity of the notes that remain outstanding range from two to five years from the date of acquisition with stated interest rates ranging from 0% to 4% . The Company has discounted these obligations to reflect a 2% to 4% market interest. Unamortized discount on the notes was de minimis as of February 28, 2015 and May 31, 2014 . Amortization is recorded as interest expense in the consolidated statements of income.

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 capital lease obligations approximates their carrying amounts based on anticipated interest rates which management believes would currently be available to the Company for similar issues of debt.

10. 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. The three levels of the hierarchy are defined as follows:

Level 1 — Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2 — Observable inputs other than quoted prices included in Level 1, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or liabilities in inactive markets, inputs other than quoted prices that are observable for the asset or liability and inputs derived principally from or corroborated by observable market data.

Level 3 — Unobservable inputs reflecting the Company’s own assumptions about inputs that market participants would use in pricing the asset or liability based on the best information available.

Mistras Group, Inc. and Subsidiaries

Notes to Unaudited Condensed Consolidated Financial Statements

(tabular dollars in thousands, except per share data)

In accordance with the fair value hierarchy described above, the following table shows the fair value of the Company’s financial liabilities that are required to be remeasured at fair value on a recurring basis:

	February 28, 2015 — Level 1	Level 2	Level 3	Total
Liabilities:
Contingent consideration	$ —	$ —	$ 8,760	$ 8,760
Total Liabilities	$ —	$ —	$ 8,760	$ 8,760

	May 31, 2014 — Level 1	Level 2	Level 3	Total
Liabilities:
Contingent consideration	$ —	$ —	$ 14,145	$ 14,145
Total Liabilities	$ —	$ —	$ 14,145	$ 14,145

The fair value of contingent consideration liabilities that was classified as Level 3 in the table above 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.

11. Commitments and Contingencies

Litigation

The Company is subject to periodic lawsuits, investigations and claims that arise in the ordinary course of business. Although the Company cannot predict with certainty the ultimate resolution of lawsuits, investigations and claims asserted against it, the Company does not believe that any currently pending legal proceeding to which the Company is a party will have a material adverse effect on its business, results of operations, cash flows or financial condition. The costs of defense and amounts that may be recovered in such matters may be covered by insurance.

In January 2012, the Company received notice of a governmental investigation concerning an environmental incident which occurred in February 2011 outside on the premises of its Cudahy, California location. No human injury or property damage was reported or appears to have been caused as a result of this incident. While management cannot predict the ultimate outcome of this matter, based on its internal investigation to date, the Company does not believe the outcome will have a material effect on its financial condition or results of operations.

During fiscal 2012 and 2013, the Company performed radiography work on the construction of pipeline projects in Georgia. The Company has received notice that the owner of the pipeline projects contends that certain of the x-ray images the Company’s technicians prepared did not meet the code quality interpretation standards required by API (American Petroleum Institute) 1104 for one of the projects. The owner of the projects is claiming damages as a result of the alleged quality defects of the Company’s x-ray images. No lawsuit has been filed at this time. The owner has requested additional information on the other project, but has not yet indicated that any of the Company’s work was defective. The Company is currently unable to determine the likely outcome or reasonably estimate the amount or range of potential liability related to this matter, and accordingly, has not established any reserves for this matter.

The Company has received a notice from an insurance company of a chemical plant alleging that the Company is liable due to faulty inspections for all or part of $46 million of damages paid by the insurance company as a result of an explosion at the facility. The Company believes it was not involved in inspecting the portion of the plant where the explosion occurred and therefore has no liability for the claim. Accordingly, the Company has not established a reserve for this matter.

Acquisition-related contingencies

The Company is liable for contingent consideration in connection with certain of its acquisitions. As of February 28, 2015 , total potential acquisition-related contingent consideration ranged from zero to approximately $23.3 million and would be payable upon the achievement of specific performance metrics by certain of the acquired companies over the next three years of operations. See Note 4 - Acquisitions to these consolidated financial statements for further discussion of the Company’s acquisitions.

12. Segment Disclosure

The Company’s three operating segments are:

• Services. This segment provides asset protection solutions primarily in North America with the largest concentration in the United States and the Canadian services business, consisting primarily of non-destructive testing and inspection and engineering services that are used to evaluate the structural integrity and reliability of critical energy, industrial and public infrastructure.

• International. This segment offers services, products and systems similar to those of the Company’s other two segments to global markets, principally in 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.

Allocations for general corporate services, including accounting, audit, and contract management, 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 Services and International segments by the Products and Systems segment are reflected in the operating performance of each segment. All such intersegment transactions are eliminated in the Company’s consolidated financial reporting.

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 determined based on internal performance measures used by the Chief Executive Officer, who is the chief operating decision maker, to assess the performance of each business in a given period and to make decisions as to resource allocations. In connection with that assessment, the Chief Executive Officer may exclude matters such as charges for share-based compensation and certain other acquisition-related charges and balances, technology and product development costs, certain gains and losses from dispositions, and litigation settlements or other charges. Certain general and administrative costs such as human resources, information technology and training are allocated to the segments. Segment income from operations also 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 depreciation on the corporate office facilities and equipment, administrative charges related to corporate personnel and other charges that cannot be readily identified for allocation to a particular segment.

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, unknown risks, uncertainties or other factors. 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 2014 Annual Report as well as those discussed in our other Securities and Exchange Commission (“SEC”) filings.

Overview

We offer our customers “one source for asset protection solutions”® and are a leading global provider of technology-enabled asset protection solutions used to evaluate the structural integrity and reliability of critical energy, industrial and public infrastructure. We combine industry-leading products and technologies, expertise in mechanical integrity (MI), Non-Destructive Testing (NDT), Destructive Testing (DT) and predictive maintenance (PdM) services, process and fixed asset engineering and consulting services, proprietary data analysis and our world class enterprise inspection database management and analysis software, PCMS, to deliver a comprehensive portfolio of customized solutions, ranging from routine inspections to complex, plant-wide asset integrity management and assessments. These mission critical solutions enhance our customers’ ability to comply with governmental safety and environmental regulations, extend the useful life of their assets, increase productivity, minimize repair costs, manage risk and avoid catastrophic disasters. Our operations consist of three reportable segments: Services, International and Products and Systems.

• Services provides asset protection solutions predominantly in North America with the largest concentration in the United States along with a growing Canadian services business, consisting primarily of NDT, inspection and engineering services that are used to evaluate the structural integrity and reliability of critical energy, industrial and public infrastructure.

• International offers services, products and systems similar to those of the other segments to global markets, principally in 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.

Table of Contents

Given the role our solutions play in ensuring the safe and efficient operation of infrastructure, we have historically provided a majority of our services to our customers on a regular, recurring basis. We serve a global customer base of companies with asset-intensive infrastructure, including companies in the oil and gas (downstream, midstream, upstream and petrochemical), power generation (natural gas, fossil, nuclear, alternative, renewable, and transmission and distribution), public infrastructure, chemicals, commercial aerospace and defense, transportation, primary metals and metalworking, pharmaceutical/biotechnology and food processing industries and research and engineering institutions.

For the last several years, we have focused on introducing 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. During this period, the demand for outsourced asset protection solutions, in general, has increased, creating demand from which our entire industry has benefited. We believe continued growth can be realized in all of our target markets. Concurrent with this growth, we are working on building our infrastructure to profitably absorb additional growth and have made a number of acquisitions in an effort to leverage our fixed costs, grow our base of experienced, certified personnel, expand our product and technical capabilities and increase our geographical reach.

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 products, technologies, resources and customers that we believe will enhance our advantages over our competition.

The global economy continues to be fragile. Global financial markets continue to experience uncertainty, including tight liquidity and credit availability, relatively low consumer confidence, high unemployment rates, slow economic growth, fluctuating oil prices and volatile currency exchange rates. However, we believe these conditions have allowed us to selectively hire new talented individuals that otherwise might not have been available to us, to acquire new technologies in order to aggressively expand our proprietary portfolio of customized solutions, and to make acquisitions of complementary businesses at reasonable valuations.

Results of Operations

Our consolidated results of operations for the three and nine months ended February 28, 2015 and 2014 were as follows:

Note About Non-GAAP Measures

Adjusted EBITDA is a performance measure used by management that is not calculated in accordance with U.S. generally accepted accounting principles (GAAP). EBITDA is defined in this Report as net income attributable to Mistras Group, Inc. plus: interest expense, provision for income taxes and depreciation and amortization. Adjusted EBITDA is defined in this Report as net income attributable to Mistras Group, Inc. 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) and, if applicable, certain non-recurring items which we note.

Our management uses Adjusted EBITDA 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. Adjusted EBITDA is also used as a performance evaluation metric for our executive and employee incentive compensation programs.

Later in the MD&A under the heading "Income for Operations", the non-GAAP financial performance measures "Income from operations before acquisition-related expense (benefit), net” is used for each of our three segments and the "Total Company", with tables reconciling the measure to a financial measure under GAAP. This non-GAAP measures excludes from the GAAP measure "Income from Operations" (a) transaction expenses related to acquisitions, such as professional fees and due diligence costs and (b) the net changes in the fair value of acquisition-related contingent consideration liabilities. These items have been excluded from the GAAP measure because these expenses and credits are not related to the Company’s or Segment’s core business operations and are related solely to the Company’s or Segment’s acquisition activities. Changes in the fair value of acquisition-related contingent consideration liabilities can be a net expense or credit in any given period, and fluctuate based upon the then current value of cash consideration the Company expects to pay in the future for prior acquisitions, without impacting cash generated from the Company’s business operations.

In the MD&A section "Liquidity and Capital Resources", we use the term free cash flow, a non-GAAP measurement. We define free cash flow as cash provided by operating activities less capital expenditures (which is classified as an investing activity). Free cash flow for the first nine months of fiscal 2015 was $22.5 million consisting of $34.3 million of operating cash flow less $11.8 million of capital expenditures. For the comparable period in fiscal 2014, free cash flow was $10.9 million consisting of $22.6 million of operating cash flow less $11.7 million of capital expenditures.

We believe investors and other users of our financial statements benefit from the presentation of EBITDA, Adjusted EBITDA and "Income from operations before acquisition-related expense (benefit), net” for each of our three segments and the "Total Company", and free cash flow in evaluating our operating performance because they provide additional tools to compare our operating performance on a consistent basis and measure underlying trends and results in our business. EBITDA and Adjusted EBITDA remove the impact of certain items that management believes do not directly reflect our core operations. For instance, Adjusted EBITDA generally excludes interest expense, taxes and depreciation and amortization, each of which can vary substantially from company to company depending upon accounting methods and the book value and age of assets, capital structure, capital investment cycles and the method by which assets were acquired. It also eliminates share-based

Table of Contents

compensation, which is a non-cash expense and is excluded by management when evaluating the underlying performance of our business operations. Similarly, we believe that "Income from operations before acquisition-related expense (benefit), net” for each of our three segments and the "Total Company", provides investors with useful information and more meaningful period over period comparisons by identifying and excluding these acquisition-related costs so that the performance of the core business operations can be identified and compared.

While Adjusted EBITDA is a term and financial measurement commonly used by investors and securities analysts, it has limitations. As a non-GAAP measurement, Adjusted EBITDA has no standard meaning and, therefore, may not be comparable with similar measurements for other companies. Adjusted EBITDA is generally limited as an analytical tool because it excludes charges and expenses we do incur as part of our operations. For example, Adjusted EBITDA excludes income taxes, but we generally incur significant U.S. federal, state and foreign income taxes each year and the provision for income taxes is a necessary cost. EBITDA and Adjusted EBITDA should not be considered in isolation or as a substitute for analyzing our results as reported under U.S. generally accepted accounting principles. In addition, acquisitions are a part of our growth strategy, and therefore acquisition-related items are a necessary cost of the Company’s business. "Income from operations before acquisition-related expense (benefit), net” for each of our three segments and for the consolidated company and “free cash flow” are not metrics used to determine incentive compensation for executives or employees.

Revenue

Revenues were $163.1 million for the three months ended February 28, 2015 compared to $151.7 million for the three months ended February 28, 2014 . Revenues were $536.6 million for the nine months ended February 28, 2015 compared to $444.3 million for the nine months ended February 28, 2014 .

Three Months

In the third quarter of fiscal 2015 , our revenue growth was primarily driven by our Services segment. Services segment revenues increased approximately 12% due to acquisition growth of approximately 13% and a decline in organic revenue of approximately 1% . Products and Systems segment revenues increased by approximately 12% driven by higher sales to international customers. International Segment revenues declined by approximately 12% , driven by an unfavorable impact of foreign exchanges rates that aggregated 10% of prior year sales, and additionally by fiscal year 2014 projects in the United Kingdom and product sales in Japan and Russia in fiscal 2014 that did not repeat in fiscal year 2015.

Table of Contents

Oil and gas revenues grew by approximately 9% and remained the Company’s most significant vertical market, comprising 53% of total Company revenues in the third quarters of fiscal 2015 and 2014 , respectively. We also experienced growth in several of our other target markets, primarily process industries and industrials. The Company’s top ten customers comprised approximately 36% of total revenues in the third quarter of fiscal 2015 compared with 43% in the third quarter of the prior fiscal year.

Nine Months

In the first nine months of fiscal 2015, our revenue growth was primarily driven by our Services segment. Services segment revenues increased 29% due to acquisition growth of approximately 19% and organic growth of approximately 10% . International Segment’s revenues declined by approximately 4% , driven by unfavorable foreign exchanges rates of 3% , and additionally by projects in the United Kingdom and product sales in Japan and Russia in fiscal 2014 that did not repeat in fiscal year 2015. Products and Systems segment revenues declined approximately 1% primarily due to lower revenue in our Acoustic Emission product line.

Oil and gas revenues grew by approximately 27% and remained the Company’s most significant vertical market, comprising 52% and 50% of total Company revenues in the first nine months of fiscal 2015 and 2014, respectively. We also experienced growth in several of our other target markets, primarily industrials, process industries, power generation and transmission, and public infrastructure. The Company’s top ten customers comprised approximately 33% of total revenues in the first nine months of fiscal 2015 compared with 38% in the first nine months of the prior fiscal year.

Gross Profit

Gross profit decreased by $0.6 million , or 1% , to $38.7 million in the third quarter of fiscal 2015 , compared with $39.3 million in the third quarter of fiscal 2014 . Gross profit increased by $13.2 million , or 10% , to $139.8 million during the first nine months of fiscal 2015 , compared with $126.6 million in the first nine months of fiscal 2014 .

Gross profit by segment for the three and nine months ended February 28, 2015 and 2014 was as follows:

Three Months

As a percentage of revenues, gross profit was 24% and 26% for the third quarters of fiscal 2015 and 2014 , respectively. The decrease in gross profit percentage was primarily attributable to the Services and International segments. Service segment gross profit margin was 150 basis points lower than in the third quarter of fiscal 2014 . Services profit margins were adversely impacted by union strikes at several of the Company’s largest customer sites, which caused previously scheduled work for some of the Company’s service technicians to be deferred or canceled during the month of February 2015. The Company estimates this adversely impacted Services revenues by 2% and Services gross margin by approximately 50 basis points. The Company's continuing investment to expand into the Canadian oil sands region reduced the Services segment operating income by approximately $1.5 million during the third quarter. International segment gross margins decreased to 21% in the third quarter of fiscal 2015 compared with 26% in the prior year, due primarily to a lower levels of both project sales in the U.K. and product sales in several countries. Products and Systems segment gross margin improved to 49% compared to 48% in the prior year, driven by actions taken to reduce its cost base.

Nine Months

Table of Contents

As a percentage of revenues, gross profit was 26% and 28% for the first nine months of fiscal 2015 and 2014 , respectively. The decrease in gross profit percentage was primarily attributable to the Services and International segments. Service segment gross profit margin declined to 25% compared to 27% in the first nine months of fiscal 2014 , due primarily to a continued investment in expanding the Company’s capability to service the Canadian oil sands region, wage increases that exceeded price increases earlier in the Company’s fiscal year and the impact from the union strikes as noted above in the three month results. International segment gross margins decreased to 24% in the first nine months of fiscal 2015 compared with 28% in the prior year, due primarily to a lower level of both project sales in the U.K. and of product sales in several countries. Products and Systems segment gross margin improved to 45% compared to 43% in the prior year driven by cost reductions.

Three Months

For the three months ended February 28, 2015 , income from operations exclusive of acquisition-related costs decreased $1.8 million , or 44% , compared with the prior year’s quarter. As a percentage of revenues, income from operations excluding acquisition-related items was 1% and 3% for the third quarters of fiscal 2015 and 2014 , respectively.

Operating expenses decreased by $1.4 million or 4% , compared with the prior year’s third quarter. The decrease was driven by lower acquisition-related expense and decreased operating expenses in the Services and Products and Systems segments. The Services segment experienced an organic year-on-year operating expenses reduction of approximately $1.4 million, excluding operating expenses incurred by recent acquisitions. The Products and Systems segment year-on-year operating expenses declined by $0.7 million , due primarily to actions taken to reduce its cost base.

Table of Contents

Nine Months

For the nine months ended February 28, 2015 , income from operations exclusive of acquisition-related costs decreased $3.6 million or 14% , compared with the prior year. As a percentage of revenues, income from operations excluding acquisition-related items was 4% and 6% for the first half of fiscal 2015 and 2014 , respectively.

Operating expenses increased by $15.3 million , or 16% compared with the prior year’s first nine months, and by $16.8 million , or 17% , excluding acquisition-related items. This increase was driven by the Services segment, which incurred a year-on-year operating expense increase of $13.9 million or 27% , exclusive of acquisition-related charges. Operating expenses incurred by recently acquired companies accounted for $10.5 million of this increase. Corporate operating expenses increased $3.0 million or 25% , exclusive of acquisition-related charges primarily due to higher salary and benefits expenses due to growth, increased share-based compensation expense and the unfavorable impact of foreign exchange rates.

Interest Expense

Interest expense was approximately $1.2 million and $0.8 million for the third quarters of fiscal 2015 and 2014 , respectively. The increase was primarily related to an increase in average borrowings in the third quarter of fiscal 2015 . Interest expense was approximately $3.4 million and $2.3 million for the first nine months of fiscal 2015 and 2014 , respectively. The increase was primarily related to an increase in average borrowings in the first nine months of fiscal 2015 .

Income Taxes

The Company’s effective income tax rate was approximately 35% and 45% for the third quarter of fiscal 2015 and 2014 , respectively. The decrease was primarily due to the impact of discrete items, partially offset by an increase in the projected annual tax rate. The Company’s effective income tax rate was approximately 38% and 37% for the first nine months of fiscal 2015 and 2014 , respectively. The increase was primarily due to a lower proportion of income from various foreign jurisdictions that carry lower tax rates and higher state income taxes, partially offset by lower permanent tax differences.

Cash Flows from Operating Activities

During the nine months ended February 28, 2015 , cash provided by our operating activities was $34.3 million , an increase of $11.7 million from the comparable period of fiscal 2014. The improvement was primarily attributable to a $25.4 million improvement in the collections of accounts receivable, offset in part by incremental net outflows of $15.0 million related to

accounts payable, and accrued expenses and other liabilities.

Cash Flows from Investing Activities

During the nine months ended February 28, 2015 , cash used in investing activities was $46.4 million , an increase of $16.2 million over the comparable period of the prior fiscal year, principally due to acquisitions totaling $35.0 million, net of cash acquired, which also represented an increase of $15.9 million over the prior year. Cash used in investing activities also included

Table of Contents

purchases of property, plant and equipment of $11.8 million . The Company generated free cash flow, (a non-GAAP measurement defined as operating cash flow reduced by capital expenditures), of $22.5 million, compared with $10.9 million in the prior year’s comparable period.

Cash Flows from Financing Activities

Net cash provided by financing activities was $15.5 million for the nine months ended February 28, 2015 , an increase of $4.3 million from the comparable period of fiscal 2014. The increase was driven by net borrowings of $35.5 million from our revolving credit facility, offset by repayments of debt, capital lease and contingent consideration obligations of approximately $20 million.

Effect of Exchange Rate Changes on Cash and Cash Equivalents

The effect of exchange rate changes on our cash and cash equivalents was less than $0.1 million and $(1.4) million for the nine months ended February 28, 2015 and 2014 , respectively.

Cash Balance and Credit Facility Borrowings

On October 31, 2014, the Company entered into a Third Amendment and Modification Agreement (the “Amendment”), to our $125.0 million revolving line of credit, the Third Amended and Restated Credit Agreement (“Credit Agreement”), dated December 21, 2011, with Bank of America, N.A., as agent for the lenders and a lender, and JPMorgan Chase Bank, N.A., Keybank, National Association and TD Bank, N.A., as lenders. The Amendment increased the Company’s revolving line of credit to $175.0 million and provides that under certain circumstances the line of credit can be increased to $225.0 million . The Company may continue to borrow up to $30.0 million in non-U.S. Dollar currencies and use up to $10.0 million of the credit limit for the issuance of letters of credit. The Amendment also extended the original maturity date of the Credit Agreement from December 20, 2016 to October 30, 2019. See Note 10 — Long-Term Debt included in this report, under the heading “Senior Credit Facility” for further detail.

As of February 28, 2015 , we had cash and cash equivalents totaling $13.4 million and available borrowing capacity of $73.6 million under our Credit Agreement with borrowings of $96.7 million and $4.7 million of letters of credit outstanding. We finance our 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 February 28, 2015 , we were in compliance with the terms of the Credit Agreement, and we will continuously monitor our compliance with the covenants contained in our Credit Agreement.

Contractual Obligations

Other than the amendment to the Credit Agreement, discussed above under “Liquidity and Capital Resources- Cash Balance and Credit Facility Borrowings”, there have been no significant changes in our contractual obligations and outstanding indebtedness as disclosed in the 2014 Annual Report.

Off-balance Sheet Arrangements

During the nine months ended February 28, 2015 , 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
