1.Description of Business & 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. Given the role our services play in ensuring the safe and efficient operation of infrastructure, the Company has historically provided a majority of its services to its customers on a regular, recurring basis. 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, aerospace and defense, transportation, primary metals and metalworking, pharmaceuticals and food processing industries.

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair statement have been included. Operating results for the three and six months ended November 30, 2011 are not necessarily indicative of the results that may be expected for the year ending May 31, 2012. The balance sheet at May 31, 2011 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements. You should read these unaudited consolidated financial statements together with the historical consolidated financial statements of the Company as filed with the Securities and Exchange Commission.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Mistras Group, Inc. and its wholly or majority-owned subsidiaries. Where 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 interest in net income, net of tax, is classified separately in the accompanying consolidated statements of operations.

All significant intercompany accounts and transactions have been eliminated in consolidation. All foreign subsidiaries’ fiscal years end on April 30, while Mistras Group, Inc. and the domestic subsidiaries’ fiscal years end on May 31. The effect of this difference in timing of reporting foreign operations on the consolidated results of operations and consolidated financial position is not significant.

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.

Revision of Prior Period Financial Statements

We have revised our consolidated statement of cash flows for the six months ended November 30, 2010 to reflect the cash flows associated with the financing of an insurance premium as cash flows from financing activities.  Such cash flows were previously reported in operating activities.  A summary of the revisions to the consolidated statements of cash flows for the six months ended November 30, 2010 is as follows:

Net increase in cash and cash equivalents during the period	(9,268		)	—			(9,268		)

A similar revision will be reflected in the statement of cash flows for the nine-month period ended February 28, 2011 in our third quarterly filing of fiscal 2012.  The impact of these revisions in the nine-month period ending February 28, 2011 was a decrease of approximately $2.7 million to net cash flows provided by operating activities with a corresponding increase to net cash flows provided by financing activities. These revisions had no impact on our annual statement of cash flows as presented in our 2011 Form 10-K.

2.Summary of Significant Accounting Policies

Revenue Recognition

Revenue recognition policies for the various sources of revenues are as follows:

Services

The Company predominantly derives revenues by providing its services on a time and material basis and recognizes revenues when services are rendered. At the end of any reporting period, there may be earned but unbilled revenues that are accrued. Payments received in advance of revenue recognition are reflected as deferred revenues.

Software

Revenues from the sale of perpetual licenses are recognized upon the delivery and acceptance of the software. Revenues from term licenses are recognized ratably over the period of the license. Revenues from maintenance, unspecified upgrades and technical support are recognized ratably over the period such items are delivered. For multiple-element arrangement software contracts that include non-software elements, and where the software is essential to the functionality of the non-software elements (collectively referred to as software multiple-element arrangements), the Company applies the rules as noted below.

Products

Revenues from product sales are recognized when risk of loss and title passes to the customer. The exceptions to this accounting treatment would be for multiple-element arrangements (described below) or those situations where specialized installation or customer acceptance is required. Payments received in advance of revenue recognition are reflected as deferred revenues.

Percentage of Completion

A portion of the Company’s revenues are generated from engineering and manufacturing of custom products under long-term contracts that may last from several months to several years, depending on the contract. Revenues from long-term contracts are recognized on the percentage-of-completion method of accounting. Under the percentage-of-completion method of accounting revenues are recognized as work is performed. The percentage of completion at any point in time is based on total costs or total labor dollars incurred to date in relation to the total estimated costs or total labor dollars estimated at completion. The percentage of completion is then applied to the total contract revenue to determine the amount of revenue to be recognized in the period. Application of the percentage-of-completion method of accounting requires the use of estimates of costs to be incurred for the performance of the contract. Contract costs include all direct materials, direct

Notes to Unaudited Consolidated Financial Statements
(tabular dollars in thousands, except per share data)

labor costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs, and all costs associated with operation of equipment. The cost estimation process is based upon the professional knowledge and experience of the Company’s engineers, project managers and financial professionals. Factors that are considered in estimating the work to be completed include the availability and productivity of labor, the nature and complexity of the work to be performed, the effect of change orders, the availability of materials, the effect of any delays in our project performance and the recoverability of any claims. Whenever revisions of estimated contract costs and 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.

Multiple-element Arrangements

The Company occasionally enters into transactions that represent multiple-element arrangements, which may include any combination of services, software, and hardware. When a sales arrangement contains multiple elements, such as hardware and services and/or software products, the Company allocates revenue to each element based on a selling price hierarchy. The selling price for a deliverable is based on its vendor specific objective evidence (VSOE) if available, third party evidence (TPE) if VSOE is not available, or estimated selling price (ESP) if neither VSOE nor TPE is available.  The Company has historically utilized the VSOE due to the nature of its products. In multiple element arrangements where more-than-incidental software deliverables are included, revenue is allocated to each separate unit of accounting for each of the non-software deliverables and to the software deliverables as a group using the relative selling prices of each of the deliverables in the arrangement based on the aforementioned selling price hierarchy. If the arrangement contains more than one software deliverable, the arrangement consideration allocated to the software deliverables as a group is then allocated to each software deliverable using the guidance for recognizing software revenue, as amended.

Use of Estimates

These unaudited consolidated financial statements have been prepared in conformity with GAAP, which requires management to make estimates and assumptions about future events that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. The more significant estimates include valuation of goodwill and intangible assets, useful lives of long-lived assets, acquisition-related contingent consideration, allowance for doubtful accounts, inventory valuation, reserves for self-insured workers compensation and health benefits and provision for income taxes.

Goodwill and Intangible Assets

Goodwill represents the excess of the purchase price over the fair market value of net assets of the acquired business at the date of acquisition. The Company tests for impairment annually, in its fiscal fourth quarter, using a two-step process. The first step identifies potential impairment by comparing the fair value of the Company’s reporting units to its carrying value. If the fair value is less than the carrying value, the second step measures the amount of impairment, if any. The impairment loss is the amount by which the carrying amount of goodwill exceeds the implied fair value of that goodwill. The most recent annual test for impairment performed for fiscal 2011 did not identify any instances of impairment and there were no events through November 30, 2011 that warranted a reconsideration of our impairment test results.

Intangible assets are recorded at cost. Intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and accounts receivable. At times, cash deposits may exceed the limits insured by the Federal Deposit Insurance Corporation. The Company believes it is not exposed to any significant credit risk or risk of nonperformance of financial institutions.

The Company sells primarily to large companies, extends reasonably short collection terms, performs credit evaluations and does not require collateral. The Company maintains reserves for potential credit losses.

We have one customer, BP plc. (BP), which accounted for 17% and 15% of revenues for the three months ended November 30, 2011 and 2010, respectively, and 16% of revenues for each of the six month periods ended November 30, 2011 and 2010.  Accounts receivable from this customer were approximately 13% and 15% of total accounts receivable, net as of November 30, 2011 and May 31, 2011, respectively. Our relationship with BP is comprised of separate contracts for non-destructive testing and inspection services with multiple affiliated entities within the broad BP organization.  We conduct business with various divisions or affiliates of the BP organization through numerous contracts covering many segments of BP’s business including downstream (refinery), midstream (pipelines) and upstream (exploration).  These contracts are typically negotiated locally with the specific BP division or affiliate, are of varying lengths, have different start and end dates and differ in terms of the scope of work and nature of services provided.  Most contracts are based on time and materials.

Equity-based Compensation

The Company measures the cost of employee services received in exchange for an award of equity instruments based upon the grant-date fair value of the award. The Company uses the “straight-line” attribution method for allocating compensation costs and recognizes the fair value of each equity award on a straight-line basis over the vesting period of the related awards.

The Company uses the Black-Scholes option-pricing model to estimate the fair value of the stock option awards as of the grant date. The Black-Scholes model, by its design, is highly complex and dependent upon key data inputs estimated by management. The primary data inputs with the greatest degree of judgment are the expected term of stock option awards and the estimated volatility of the Company’s common stock price. The Black-Scholes model is sensitive to changes in these two variables.  Since the Company’s initial public offering (IPO), the expected term of the Company’s stock options is generally determined using the mid-point between the vesting period and the end of the contractual term. Expected stock price volatility is typically based on the daily historical trading data for a period equal to the expected term. Because the Company’s historical trading data only dates back to October 8, 2009, the first trading date after its IPO, the Company has estimated expected volatility using an analysis of the stock price volatility of comparable peer companies.  Prior to the Company’s IPO, the exercise price equaled the estimated fair market value of the Company’s common stock, as determined by its board of directors. Since the Company’s IPO, the exercise price of stock option grants is determined using the closing market price of the Company’s common stock on the date of grant.

Recent Accounting Pronouncements

In October 2009, the FASB issued ASU 2009-13, Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements (a consensus of the FASB Emerging Issues Task Force), which requires companies to allocate the overall consideration in multiple-element arrangements to each deliverable by using a best estimate of the selling price of individual deliverables in the arrangement in the absence of vendor-specific objective evidence or other third-party evidence of the selling price. Effective June 1, 2011, the Company adopted, on a prospective basis, the provisions of this updated accounting standard related to revenue recognition associated with contractual arrangements involving multiple elements. The adoption of this pronouncement did not have a material impact on the Company’s consolidated financial statements.

In April 2010, the FASB issued ASU 2010-17, Revenue Recognition—Milestone Method (Topic 605): Milestone Method of Revenue Recognition (a consensus of the FASB Emerging Issues Task Force).  ASU 2010-17 provides guidance on applying the milestone method to milestone payments for achieving specified performance measure when those payments are related to uncertain future events limited to transactions involving research and development. Entities can make an accounting policy election to recognize arrangement consideration received for achieving specified performance measures during the period in which the milestones are achieved, provided certain criteria are met. Effective June 1, 2011, the Company adopted, on a prospective basis, the provisions of this updated accounting standard related to milestones. The adoption of this pronouncement did not have a material impact on the Company’s consolidated financial statements.

In June 2011, the FASB issued ASU 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. ASU 2011-05 allows an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. This authoritative guidance eliminates the option to present the components of other comprehensive income as part of the statement of equity. ASU 2011-05 does not change the items that must be reported in

other comprehensive income, when an item of other comprehensive income must be reclassified to net income, the Company’s option to present components of other comprehensive income either net of related tax effects or before related tax effects, nor does it affect how earnings per share is calculated or presented. ASU 2011-05 requires retrospective application, and it is effective for fiscal years and interim periods within those years, beginning after December 15, 2011.  Early adoption is permitted. The Company does not expect that the adoption of this pronouncement will have a material impact on the Company’s consolidated financial statements.

In September 2011, the FASB issued Accounting Standards Update (ASU) 2011-08, Intangibles-Goodwill and Other (Topic 350): Testing Goodwill for Impairment.  ASU 2011-08 permits an entity to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that this is the case, it is then necessary to perform the currently prescribed two-step goodwill impairment test. Otherwise, the two-step goodwill impairment test is not required. ASU 2011-08 is effective for the Company in fiscal 2013 and earlier adoption is permitted. The Company does not expect that the adoption of this pronouncement will have a material impact on the Company’s consolidated financial statements.

3.Capitalization

Common Stock

In May 2011, the Company completed a secondary offering of 3,754,061 shares of common stock at a price of $16.00 per share.  The Company sold 989,660 shares and 2,764,401 shares were sold by a selling stockholder.  The Company received net proceeds of approximately $14.7 million from the offering. The Company used the net proceeds for general corporate purposes including the reduction of outstanding indebtedness, acquisitions, capital expenditures and working capital.

Dividends on common stock will be paid when, and if declared by the board of directors. Each holder of common stock is entitled to vote on all matters and is entitled to one vote for each share held.

Equity Awards

In September 2009, the Company’s board of directors and shareholders adopted and approved the 2009 Long-Term Incentive Plan (the 2009 Plan), which became effective upon the closing of the IPO. Awards may be in the form of stock options, restricted stock units and other forms of stock-based incentives, including stock appreciation rights and deferred stock rights. The term of each incentive and non-qualified stock option is ten years. Vesting generally occurs over a period of four years, the expense for which is recorded on a straight-line basis over the requisite service period. The 2009 Plan allows for the grant of awards of up to approximately 2,286,000 shares of common stock, of which 1,700,000 shares were available for future grants as of November 30, 2011. Prior to the Company’s IPO in October 2009, the Company had two stock option plans: (i) the 1995 Incentive Stock Option and Restricted Stock Purchase Plan (the 1995 Plan), and (ii) the 2007 Stock Option Plan (the 2007 Plan). No additional awards may be granted from these two plans. As of November 30, 2011, there were approximately 2,665,000 stock options outstanding and approximately 449,000 unvested restricted stock units outstanding under the 2009 Plan, the 2007 Plan, and the 1995 Plan.

The fair value of the Company’s stock option awards for the six months ended November 30, 2010 was estimated at the date of grant using the Black-Scholes option-pricing model with the range of assumptions below.  No stock options were granted during the six months ended November 30, 2011.

	Six months ended November 30, 2010
Dividend yield	0.0	%
Expected volatility	44	%
Risk-free interest rate	2.6	%
Expected term (years)	6.3

The Company recognized stock-based compensation expense related to stock option awards of approximately $0.9 million for each of the three month periods ended November 30, 2011 and 2010. For the six months ended November 30, 2011 and

10

(tabular dollars in thousands, except per share data)

2010, the Company recognized stock-based compensation expense related to stock option awards of $1.7 million and $1.6 million, respectively.  As of November 30, 2011, there was approximately $5.3 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 1.7 years.  Cash proceeds from and the aggregate intrinsic value of stock options exercised during the three and six months ended November 30, 2011 and 2010 were as follows:

	Three months ended November 30,				Six months ended November 30,
	2011		2010		2011		2010
Cash proceeds from options exercised	$	1,268	$	—	$	1,325	$	—
Aggregate intrinsic value of options exercised	$	3,026	$	—	$	3,062	$	—

The Company also recognized approximately $0.5 million and $0.1 million in stock-based compensation expense related to restricted stock unit awards during the three months ended November 30, 2011 and 2010, respectively.  For the six months ended November 30, 2011 and 2010, the Company recognized stock-based compensation expense related to restricted stock unit awards of $0.7 million and $0.2 million, respectively.  As of November, 2011, there was approximately $6.6 million of unrecognized compensation costs, net of estimated forfeitures, related to restricted stock unit awards, which are expected to be recognized over a remaining weighted average period of 3.5 years.

In October 2011, the Company granted approximately 9,000 shares of fully-vested common stock to its five non-employee directors, in connection with its non-employee director compensation plan.  These shares had a grant date fair value of approximately $0.2 million, which was recorded as stock-based compensation expense during the three and six months ended November 30, 2011.

During the six months ended November 30, 2011, approximately 52,000 restricted stock units vested, the fair value of which was $0.5 million. Upon vesting, restricted stock units are generally net share-settled to cover the required withholding tax and the remaining amount is converted into an equivalent number of shares of common stock. The restricted stock units that vested in the first six months of fiscal 2012 were net-share settled such that the Company withheld shares with value equivalent to the employees’ minimum statutory obligation for the applicable income and other employment taxes, and remitted the cash to the appropriate taxing authorities. The Company withheld approximately 16,000 shares based on the value of the restricted stock units on their vesting date as determined by the Company’s closing stock price. Total payments for the employees’ tax obligations to the taxing authorities were $0.3 million and are reflected as a financing activity within the consolidated statements of cash flows. These net-share settlements had the effect of share repurchases by the Company as they reduced and retired the number of shares that would have otherwise been issued as a result of the vesting and did not represent an expense to the Company.

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 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:

5.Acquisitions

The Company made four acquisitions during the six months ended November 30, 2011. These acquisitions were asset protection companies specializing in advanced ultrasonic inspection, NDT services and inspection, ultrasonic testing (UT) products and systems, and in-house component inspection. These companies were acquired to complement our service and product offerings within our Services, Products and Systems, and International segments. One acquisition was an asset purchases that met the definition of “acquisitions of businesses” under the provision of FASB Accounting Standards Codification (ASC) 805-10-20, and has been integrated into our Services segment. In the three remaining acquisitions, we acquired 100% of the common stock of the acquirees, all of which have been integrated into our International segment. In addition to the cash and debt consideration related to acquisitions closed during the six months ended November 30, 2011, the Company also accrued a liability of approximately $0.8 million as of November 30, 2011, which represents the estimated fair value of contingent consideration expected to be payable in the event that certain of the acquired companies achieve specific performance metrics over the next four years of operations. The total potential contingent consideration ranges from zero to $0.9 million for these acquisitions.

Assets and liabilities of the acquired businesses were included in the consolidated balance sheets as of November 30, 2011 based on their estimated fair value on the date of acquisition as determined in a purchase price allocation, using available information and making assumptions management believes are reasonable. The Company is still in the process of completing its valuations of the intangible assets of the acquisitions in our International segment. We believe we will have finalized these valuations and purchase price allocations prior to the end of our third fiscal quarter ending February 29, 2012. The Company’s preliminary allocation of purchase price for these acquisitions is included in the table below. Results of operations for the period from acquisition date are reported in each respective operating segment’s statement of operations. The following table summarizes the estimated fair value of the assets acquired and liabilities assumed at the date of acquisition:

The amortization period of intangible assets acquired ranges from one to fifteen years. The Company recorded approximately $7.9 million of goodwill in connection with its fiscal 2012 acquisitions, reflecting the strategic fit and revenue and earnings growth potential of these businesses. Substantially all of the goodwill recognized is expected to be deductible for tax purposes.

Revenues included in the consolidated statement of operations for the three and six months ended November 30, 2011 from these acquisitions for the period subsequent to the closing of each transaction was approximately $1.9 million and $2.3 million, respectively. Loss from operations included in the consolidated statement of operations for the three and six months ended November 30, 2011 from these acquisitions for the period subsequent to the closing of each transaction was approximately ($11) thousand and ($67) thousand, respectively.

The unaudited pro forma information for the periods set forth below gives effect to the fiscal 2012 acquisitions as if they had occurred at the beginning of each period presented. The pro forma information is presented for informational purposes only and is not necessarily indicative of the results of operations that actually would have been achieved had the acquisitions been consummated as of that time (unaudited, in thousands):

	Three months ended November 30,				Six months ended November 30,
	2011		2010		2011		2010
Revenues	$	119,503	$	94,270	$	216,297	$	168,139
Income from operations	$	14,244	$	10,073	$	19,947	$	12,925

During the three and six month periods ended November 30, 2011, the Company adjusted the fair value of certain acquisition-related contingent consideration liabilities. The adjustments resulted in a net decrease of $0.7 million to the Company’s acquisition-related contingent consideration liabilities, which were approximately $4.8 million as of November 30, 2011 and recorded on the balance sheet in accrued expenses and other liabilities. These adjustments also resulted in a corresponding net increase to income from operations of $0.7 million. Additionally, the Company incurred certain acquisition-related costs of $0.4 million in connection with due diligence, professional fees, and other expenses for its fiscal 2012 acquisition activity. Both the fair value adjustments to acquisition-related contingent consideration liabilities and the acquisition-related expenses have been classified as acquisition-related costs in the statement of operations for the three and six months ended November 30, 2011. Acquisition-related costs for the Company’s fiscal 2011 acquisition activity were insignificant for the three and six months ended November 30, 2010.

Senior Credit Facility

In July 2009, the Company entered into a Second Amended and Restated Credit Agreement with Bank of America, N.A., JPMorgan Chase Bank, N.A., TD Bank, N.A. and Capital One, N.A., which provided for a $25.0 million term loan and a $55.0 million secured revolving credit facility. The outstanding principal balance of the term loan was subsequently repaid in October 2009 in connection with the Company’s IPO and may not be re-borrowed under the current credit agreement. The Company also repaid the outstanding balance of the revolving credit facility but may re-borrow under the revolving credit facility at any time during the term of the agreement. As of November 30, 2011, there were outstanding borrowings of $22.8 million and a total of $3.9 million of outstanding letters of credit under the existing revolving credit facility.

In December 2011, the Company entered into a Third Amended and Restated Credit Agreement (Credit Agreement) 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 Credit Agreement provides the Company with a $125.0 million revolving line of credit, which, under certain circumstances, can be increased to $150.0 million.  The Credit Agreement has a maturity date of December 20, 2016 and permits the Company to borrow up to $30.0 million in non-U.S. dollar currencies and to use up to $10.0 million of the credit limit for the issuance of letters of credit.   Loans under the Credit Agreement bear interest at LIBOR or base rate, at the option of the Company, plus an applicable LIBOR margin ranging from 1% to 2%, or base rate margin ranging from -1.25% to -.25%, based upon its 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 2.5 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 if the Funded Debt

15

Mistras Group, Inc. and Subsidiaries
Notes to Unaudited Consolidated Financial Statements
(tabular dollars in thousands, except per share data)

Leverage Ratio exceeds 3.0 to 1.  The Credit Agreement is secured by liens on substantially all of the assets of the Company.

The Credit Agreement contains financial covenants requiring that the Company maintain a Funded Debt Leverage Ratio of less 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 its 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.

In December 2011, outstanding borrowings under the former credit agreement were repaid in full using proceeds from the Credit Agreement.

Notes Payable and Other

In connection with acquisitions the Company has completed, it has, at various times, issued subordinated notes payable to the sellers. The maturity of these notes range from three to five years from the date of acquisition with interest rates ranging from 0% to 7%. The Company has discounted these obligations to reflect a 3.5% to 10% imputed interest rate. Unamortized discount on these notes totaled approximately $0.1 million as of November 30, 2011 and May 31, 2011. Amortization is recorded as interest expense in the consolidated statement of operations. The Company also has payment obligations to the sellers or the shareholders of the sellers pursuant to non-compete agreements which require the sellers and shareholders of the sellers not to compete with the Company.  The payment obligations under these agreement s range from 3 to 5 years.

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.

The Company was a defendant in two related purported class action lawsuits in California, based upon alleged violations of California labor and employment law: Quiroz v. Mistras Group, Inc., et al, U.S. District Court, Central District of California (Case No. CV09-7146 PSG), filed in September 2009, and Ballard v. Mistras Group, Inc., et al, U.S. District Court, Central District of California (Case No. 2:10-cv-03186 (PSG)), filed in March 2010.  The settlement for these cases received final court approval in August 2011.  The Company took a charge during the three month and six month periods ending November 30, 2010 of $0.4 million and $0.1 million, respectively, for these cases.

Acquisition-related contingencies

The Company is liable for contingent consideration in connection with certain of its acquisitions. As of November 30, 2011, total potential acquisition-related contingent consideration ranged from $0 to $10.1 million and would be payable upon the achievement of specific performance metrics by certain of the acquired companies over the next four years of operations. See Note 5 to these consolidated financial statements for further discussion of the Company’s acquisitions.

12.Subsequent Event

In December 2011, the Company entered into a Third Amended and Restated Credit Agreement (Credit Agreement) 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 Credit Agreement provides the Company with a $125.0 million revolving line of credit, which, under certain circumstances, can be increased to $150.0 million.  The Credit Agreement has a maturity date of December 20, 2016 and permits the Company to borrow up to $30.0 million in non-U.S. dollar currencies and to use up to $10.0 million of the credit limit for the issuance of letters of credit.    See Note 10 to these consolidated financial statements for further discussion of the Company’s Credit Agreement.

In December 2011, the Company completed the acquisition of three asset protection businesses to continue its strategic efforts in market expansion. Prior to November 30, 2011, the Company funded an escrow account in the amount of $3.7 million for one of the acquisitions. These disbursed funds were classified as restricted cash on the consolidated balance sheet as of November 30, 2011. The Company’s cash outlay for the remaining two acquisitions was approximately $9.6 million and was made subsequent to November 30, 2011. 

In addition to the cash consideration, the agreement allows for contingent consideration to be earned based upon certain of the acquired companies reaching specific performance metrics over the next three years of operation. The Company is in the process of completing the preliminary purchase price allocation. These acquisitions were not individually significant and no pro forma information has been included.

13.Segment Disclosure

The Company’s three segments are:

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

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.

International. This segment offers services, products and systems similar to those of our 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 our Products and Systems segment.

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.

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 stock-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.

Selected consolidated financial information by segment for the periods shown was as follows:

ITEM 2.                  Management’s Discussion and Analysis of Financial Condition and Results of Operations

This Quarterly Report on Form 10-Q contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 (Securities Act), and Section 21E of the Securities Exchange Act of 1934 (Exchange Act). Forward-looking statements reflect our current estimates, expectations and projections about our future results, performance, prospects and opportunities. Forward-looking statements include, among other things, the information concerning our possible future results of operations, business and growth strategies, financing plans, our competitive position and the effects of competition, the projected growth of the industries in which we operate, the benefits and synergies to be obtained from our completed and any future acquisitions, and statements of management’s goals and objectives, and other similar expressions concerning matters that are not historical facts. Words such as “may,” “should,” “could,” “would,” “predicts,” “potential,” “continue,” “expects,” “anticipates,” “future,” “intends,” “plans,” “believes,” “estimates,” “appears,” “projects” and similar expressions, as well as statements in the future tense, identify forward-looking statements. Forward-looking statements should not be read as a guarantee of future performance or results, and will not necessarily be accurate indications of the times at, or by which, such performance or results will be achieved. Forward-looking information is based on information available at the time and management’s good faith belief with respect to future events, and is subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in the statements. Important factors that could cause such differences include, but are not limited to the factors discussed under the “Risk Factors” section below.

The following is a discussion and analysis of our financial condition and results of operations and should be read together with our condensed consolidated financial statements and related notes to the condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q and our audited consolidated financial statements and related notes to the audited consolidated financial statements included in our Annual Report on Form 10-K. In this quarterly report, our fiscal years, which end on May 31, are identified according to the calendar year in which they end (e.g., the fiscal year ended May 31, 2011 is referred to as “fiscal 2011”), and unless otherwise specified or the context otherwise requires, “Mistras,” “the Company,” “we,” “us” and “our” refer to Mistras Group, Inc. and its consolidated subsidiaries.

Overview

We are 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. We combine 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 our 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. Given the role our services 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, fossil and nuclear power, public infrastructure, chemicals, aerospace and defense, transportation, primary metals and metalworking, pharmaceuticals and food processing industries. During fiscal 2011, we provided our asset protection solutions to approximately 5,600 customers. As of November 30, 2011, we had approximately 3,100 employees, including approximately 30 Ph.D.’s and 100 other degreed engineers and certified technicians, in approximately 81 offices across 15 countries. We have established long-term relationships as a critical solutions provider to many leading companies in our target markets. Our current principal market is the oil and gas industry, which accounted for approximately 57% and 60% of our second quarter revenues for fiscal 2012 and 2011, respectively.

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 have experienced compounded annual growth rate (CAGR) for revenue of 31% over the last three fiscal years, including the impact of acquisitions and currency fluctuations. We believe further growth can be realized in all of our target markets. Concurrent with this growth, we have worked to build our infrastructure to profitably absorb additional growth and have made a number of small 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.

21

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 competitive advantages over our competition.

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

Note About Non-GAAP Measures

EBITDA and Adjusted EBITDA are performance measures used by management that are not calculated in accordance with U.S. generally accepted accounting principles (GAAP).  EBITDA is defined in this Quarterly 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 Quarterly Report as net income attributable to Mistras Group, Inc. plus: interest expense, provision for income taxes, depreciation and amortization, stock-based compensation expense, and, if applicable, certain acquisition related costs (including adjustments to the fair value of contingent consideration) and certain one-time and generally non-recurring items (which items are described below or in the reconciliation table above).

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 on which to base executive and employee incentive compensation programs.

We believe investors and other users of our financial statements benefit from the presentation of Adjusted EBITDA in evaluating our operating performance because it provides an additional tool to compare our operating performance on a consistent basis and measure underlying trends and results in our business. Adjusted EBITDA removes 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 stock-based compensation, which is a non-cash expense and is excluded by management when evaluating the underlying performance of our business operations.

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. 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.

Revenues. Revenues were $114.2 million for the three months ended November 30, 2011 compared to $88.8 million for the three months ended November 30, 2010.   Revenues by segment for the three months ended November 30, 2011 and 2010 were as follows:

	Three months ended November 30,

	$	114,220		$	88,837

We estimate our growth rates for the three months ended November 30, 2011 and 2010, respectively, were as follows:

	Three months ended November 30,
	2011			2010
	($ in thousands)
Revenue growth	$	25,383		$	16,938
% Growth over prior year	28.6		%	23.6		%
Comprised of:
% of organic growth	19.4		%	17.6		%
% of acquisition growth	8.8		%	6.0		%
% foreign exchange increase (decrease)	0.4		%	0.0		%
	28.6		%	23.6		%

Revenues increased $25.4 million, or approximately 29%, for the three months ended November 30, 2011 compared to the three months ended November 30, 2010 as a result of growth in all our segments, but principally attributable to growth in our Services segment. For the second quarter of fiscal 2012 and 2011, we estimate that our organic growth rate, as compared to growth driven by acquisitions, was approximately 19% and 18%, respectively. This organic growth was driven by an increase in demand for our inspection services coupled with an increase in our “run and maintain” or “evergreen” contracts.  In the second quarter of fiscal 2012, we estimate that our acquisition growth was approximately 9% compared to approximately 6% in the second quarter of fiscal 2011. We completed four acquisitions during the six months ended November 30, 2011 and three acquisitions during the six months ended November 30, 2010.

We continued to experience growth in many of our target markets during the second quarter of fiscal 2012.   Oil and gas is our largest target market and represented approximately 57% of total revenues in the second quarter of fiscal 2012, compared to approximately 60% in the second quarter of fiscal 2011. Oil and gas revenue in the second quarter of fiscal 2012 increased approximately 21% over the prior year with the largest increases coming from the downstream and upstream sections of the oil and gas industry. We also experienced growth in several of our other target markets outside of oil and gas, including chemical, industrial markets, and transportation. Taken as a group, revenues for all target markets other than oil and gas grew approximately 39% in the second quarter of fiscal 2012 over the prior year period. Our largest customer in both periods was BP plc., (BP), accounting for approximately 17% of our revenues in the second quarter of fiscal 2012 and approximately 15% in the second quarter of fiscal 2011.   Our top ten customers represented approximately 44% of our revenues in the second quarter of fiscal 2012 compared to 42% in the same quarter last year.

Gross Profit. Our gross profit was $35.2 million and increased $7.4 million, or 27% in the second quarter of fiscal 2012 compared to $27.8 million in the second quarter of fiscal 2011. Gross profit by segment for the three months ended November 30, 2011 and 2010 were as follows:

Corporate and eliminations	(347		)	(26		)
	$	35,215		$	27,808

As a percentage of revenues, our gross profit and its components for the three months ended November 30, 2011 and 2010, respectively, were as follows:

	Three months ended November 30,

Depreciation	(3.3		)%	(3.7		)%
Total	30.8		%	31.3		%
Gross profit % increase (decrease) from prior year	(0.5		)%	(0.7		)%

As a percentage of revenues, our gross profit decreased 50 basis points to approximately 31% in the second quarter of fiscal 2012 compared to the second quarter of fiscal 2011. Cost of revenues, excluding depreciation, as a percentage of revenues was approximately 66% and 65% in the second quarter of fiscal 2012 and fiscal 2011, respectively. Depreciation expense included in the determination of gross profit for the second quarter of fiscal 2012 and fiscal 2011 was $3.7 million and $3.3 million, respectively.

The 50 basis point decrease in our gross profit as a percentage of revenues was primarily attributable to a change in the mix of revenues generated during the quarter and slightly higher unbilled direct labor. Revenue from the oil and gas industry increased approximately 21% during the second quarter of fiscal 2012 and represented approximately 57% of total revenues. Revenue from this industry tends to have lower gross margins than other industries due to the existence of longer term contracts which typically have a high concentration of lower margin, traditional NDT services. Offsetting the impact of higher oil and gas revenues in the second quarter of fiscal 2012 was revenue growth of approximately 39% in all other industries, where gross margins tend to be higher.  In addition, revenues from Advanced NDT services, which have higher margins than traditional NDT services, increased more than 35% during the second quarter of fiscal 2012 and now represent approximately 16% of our Services segment revenues compared to approximately 15% in the comparable quarter of fiscal 2011.

Unbilled direct labor increased $0.6 million in the second quarter of fiscal 2012 compared to the second quarter of fiscal 2011.  Unbilled direct labor includes professional training time for our technicians which increased as a result of the increase in technicians in the second quarter of fiscal 2012 compared to the second quarter of fiscal 2011.

Income from Operations. Our income from operations by segment for the three months ended November 30, 2011 and 2010 were as follows:

25

	Three months ended November 30,
	2011			2010
	($ in thousands)
Income from operations
Services	$	13,616		$	10,249

International	1,354			1,082
Corporate and eliminations	(3,450		)	(2,110		)
	$	14,071		$	10,197

Our income from operations of $14.1 million for the second quarter of fiscal 2012 increased $3.9 million, or 38%, compared to the second quarter of fiscal 2011. As a percentage of revenues, our income from operations was approximately 12% and 11% in the second quarter of fiscal 2012 and fiscal 2011, respectively.

Our selling, general and administrative (SG&A) expenses for the second quarter of fiscal 2012 increased approximately $3.8 million over the second quarter of fiscal 2011. As a percentage of revenues, SG&A expenses for the second quarter of fiscal 2012 decreased to approximately 17% from approximately 18% in the second quarter of fiscal 2011.  The increase in expense was primarily due to the cost of additional salary and other infrastructure costs to support our growth in revenues, including the addition of new locations and personnel in connection with our acquisitions. Our recent acquisitions accounted for approximately $1.0 million of the total increase in SG&A expenses. Excluding acquisitions, our SG&A expenses included higher compensation and benefit expenses of $1.8 million over the same period in the prior year attributed to normal salary increases, as well as our investment in additional management and corporate staff to support our growth. Other increases in SG&A expenses, excluding acquisitions, included foreign currency losses of $0.8 million, stock compensation costs of $0.5 million, and insurance expense of $0.3 million. Depreciation and amortization included in the determination of income from operations for the second quarter of fiscal 2012 and fiscal 2011 was $1.5 million and $1.3 million, respectively, each representing approximately 1% of revenues.

Our acquisition-related costs for the second quarter of fiscal 2012 were due to adjustments to the estimated fair value of certain acquisition-related contingent consideration liabilities resulting in a net increase to income from operations of $0.7 million. This was offset by $0.4 million in professional fees and other expenses in connection with our fiscal 2012 acquisition activity. Acquisition-related costs for the three months ended November 30, 2010 were insignificant.

Interest Expense. Interest expense was $1.1 million and $0.7 million for the second quarter of fiscal 2012 and 2011, respectively. The increase in the second quarter of fiscal 2012 related to an increase in average borrowings in the current year quarter compared to the prior year and interest accretion from the estimated fair value of our contingent consideration related to our acquisitions.

Net Loss Attributable to Noncontrolling Interests, net of taxes. The net loss attributable to noncontrolling interests for the three months ended November 30, 2011 is primarily related to the net loss incurred by Diapac, our subsidiary in Russia, and the net loss incurred by IPS, a subsidiary in France.

Income Taxes. Our effective income tax rate was approximately 39% for the second quarter of fiscal 2012 compared to approximately 40% for the second quarter of fiscal 2011.  The decrease was primarily due to the impact of permanent tax differences and a decrease in state and foreign tax rates.

Net Income Attributable to Mistras Group, Inc. Net income attributable to Mistras Group, Inc. for the second quarter of fiscal 2012 was $8.0 million, or 7% of our revenues, an increase of $2.3 million over the second quarter of fiscal 2011, which was $5.7 million, or 6% of revenues. The increase in net income was primarily the result of our revenue growth, partially offset by increases in our SG&A expenses and our provision for income taxes.

Revenues. Revenues were $205.7 million for six months ended November 30, 2011 compared to $157.2 million for the six months ended November 30, 2010.   Revenues by segment for the six months ended November 30, 2011 and 2010 were as follows:

We estimate our growth rates for the six months ended November 30, 2011 and 2010, respectively, were as follows:

	Six months ended November 30,
	2011			2010
	($ in thousands)
Revenue growth	$	48,420		$	29,259
% Growth over prior year	30.8		%	22.9		%
Comprised of:
% of organic growth	19.4		%	16.2		%
% of acquisition growth	10.3		%	6.8		%
% foreign exchange increase (decrease)	1.1		%	(0.1		)%
	30.8		%	22.9		%

Revenues increased $48.4 million, or approximately 31%, for the six months ended November 30, 2011 compared to the six months ended November 30, 2010 as a result of growth in all our segments, but principally attributable to growth in our Services segment. For the six months ended November 30, 2011 and 2010, we estimate that our organic growth rate, as compared to growth driven by acquisitions, was approximately 19% and 16%, respectively. This organic growth was driven by an increase in demand for our inspection services coupled with an increase in our “run and maintain” or “evergreen” contracts.  For the six months ended November 30, 2011, we estimate that our acquisition growth was approximately 10% compared to approximately 7%, in the six months ended November 30, 2010. We completed four acquisitions during the six months ended November 30, 2011 and three acquisitions during the six months ended November 30, 2010.

We continued to experience growth in many of our target markets during the first six months of fiscal 2012.  Oil and gas is our largest target market and in the first six months of fiscal 2012 represented approximately 56% of total revenues, compared to approximately 60% in the comparable period of fiscal 2011. Oil and gas revenue in the first six months of fiscal 2012 increased approximately 23% over the prior year period with the largest increases coming from the downstream and midstream sections of the oil and gas industry. We also experienced growth in several of our other target markets outside of oil and gas, including chemical, industrial markets, and aerospace and defense. Taken as a group, revenues for all target markets other than oil and gas grew approximately 43% in the six months ended November 30, 2011 over the comparable prior year period. Our largest customer in both periods was BP plc., (BP), accounting for approximately 16% of our revenues in each six month period ended November 30, 2011 and 2010.   Our top ten customers represented approximately 41% of our revenues in each six month period ended November 30, 2011 and 2010.

Gross Profit. Our gross profit was $62.6 million and increased $14.0 million, or 29% during the six months ended November 30, 2011 compared to $48.6 million during the six months ended November 30, 2010. Gross profit by segment for the six months ended November 30, 2011 and 2010 were as follows:

As a percentage of revenues, our gross profit and its components for the six months ended November 30, 2011 and 2010, respectively, were as follows:

Depreciation	(3.5		)%	(4.0		)%
Total	30.5		%	30.9		%
Gross profit % increase (decrease) from prior year	(0.4		)%	(0.5		)%

As a percentage of revenues, our gross profit decreased 40 basis points to approximately 31% in the first six months of fiscal 2012 compared to the comparable prior year period. Cost of revenues, excluding depreciation, as a percentage of revenues was approximately 66% and 65% in the six months ended November 30, 2011 and 2010, respectively. Depreciation expense included in the determination of gross profit for the six months ended November 30, 2011 and 2010 was $7.2 million and $6.3 million, respectively.

The 40 basis point decrease in our gross profit as a percentage of revenues was primarily attributable to a change in the mix of revenues generated during the quarter and slightly higher unbilled direct labor. Revenue from the oil and gas industry increased approximately 23% during the first six months of fiscal 2012 and represented approximately 56% of total revenues. Revenue from this industry tends to have lower gross margins than other industries due to the existence of longer term contracts which typically have a high concentration of lower margin, traditional NDT services. Offsetting the impact of higher oil and gas revenues in the first six months of fiscal 2012 was revenue growth of approximately 43% in all other industries, where gross margins tend to be higher.  In addition, revenues from Advanced NDT services, which have higher margins than traditional NDT services, increased by more than 45% during the first six months of fiscal 2012 and now represent approximately 16% of our Services segment revenues compared to approximately 15% in the comparable period of fiscal 2011.

Unbilled direct labor increased $1.2 million in the first six months of fiscal 2012 compared to the first six months of fiscal 2011.  Unbilled direct labor includes professional training time for our technicians which increased as a result of the increase in technicians in the first six months of fiscal 2012 compared to the prior year period.

Income from Operations. Our income from operations by segment for the six months ended November 30, 2011 and 2010 were as follows:

	Six months ended November 30,
	2011			2010

International	2,090			2,110
Corporate and eliminations	(6,386		)	(4,461		)
	$	20,042		$	13,513

Our income from operations of $20.0 million for the six months November 30, 2011 increased $6.5 million, or 48%, compared to $13.5 million for the six months ended November 30, 2010. As a percentage of revenues, our income from operations was approximately 10% and 9% for the six months ended November 30, 2011 and 2010, respectively.

Our selling, general and administrative (SG&A) expenses for the six months ended November 30, 2011 increased approximately $7.7 million over the comparable prior year period. As a percentage of revenues, SG&A expenses for the first six months of fiscal 2012 decreased to approximately 19% from approximately 20% for the first six months of fiscal 2011.  The increase in expense was primarily due to the cost of additional salary and other infrastructure costs to support our growth in revenues, including the addition of new locations and personnel in connection with our acquisitions. Our recent acquisitions accounted for approximately $2.4 million of the total increase in SG&A expenses. Excluding acquisitions, our SG&A expenses included higher compensation and benefit expenses of $3.7 million over the same period in the prior year attributed to normal salary increases, as well as our investment in additional management and corporate staff to support our growth. Other increases in SG&A expenses, excluding acquisitions, included foreign currency losses of $0.8 million, stock compensation costs of $0.8 million and insurance expense of $0.6 million.  Depreciation and amortization included in the determination of income from operations for the six months ended November 30, 2011 and 2010 was $3.0 million, or 1% of revenues, and $2.5 million, or 2% of revenues, respectively.

Our acquisition-related costs for the six months ended November 30, 2011 were due to adjustments to the estimated fair value of certain acquisition-related contingent consideration liabilities resulting in a net increase to income from operations of $0.7 million. This was offset by $0.4 million in professional fees and other expenses in connection with our fiscal 2012 acquisition activity. Acquisition-related costs for the six months ended November 30, 2010 were insignificant.

Interest Expense. Interest expense for the six months ended November 30, 2011 was $1.8 million, an increase of $0.4 million when compared to the prior year period.  This increase primarily related to an increase in average borrowings in the current year as well as interest accretion from the estimated fair value of contingent consideration related to our acquisitions. The increase was offset by market rate adjustments of our interest rate swap outstanding in the prior year.

Net Loss Attributable to Noncontrolling Interests, net of taxes. The net loss attributable to noncontrolling interests for the six months ended November 30, 2011 is primarily related to the net loss incurred by Diapac, our subsidiary in Russia, and the net loss incurred by IPS, a subsidiary in France.

Income Taxes. Our effective income tax rate was approximately 39% for the six months ended November 30, 2011 compared to approximately 40% for the six months ended November 30, 2010.  The decrease was primarily due to the impact of permanent tax differences and a decrease in state and foreign tax rates.

Net Income Attributable to Mistras Group, Inc. Net income attributable to Mistras Group, Inc. for the six months ended November 30, 2011 was $11.2 million, an increase of $3.9 million over net income attributable to Mistras Group, Inc. for the six months ended November 30, 2010, which was $7.3 million, each representing 5% of revenues. The increase in net income was primarily the result of our revenue growth, partially offset by increases in our SG&A expenses and our provision for income taxes.

Cash Flows from Operating Activities

During the six months ended November 30, 2011, cash provided by our operating activities was $0.4 million, a decrease of $8.6 million from the comparable period of fiscal 2011. Positive operating cash flow was primarily attributable to higher net income, excluding depreciation, amortization and other non-cash expenses of $24.5 million offset by $24.0 million of cash utilized to fund an increase in our working capital, which primarily related to an increase in our trade accounts receivable.

During the six months ended November 30, 2010, cash provided by our operating activities was $9.0 million, an increase of $0.4 million from the comparable period of fiscal 2010. Positive operating cash flow was primarily attributable to net income, excluding depreciation and amortization and other non-cash expenses of $17.7 million offset by $8.6 million of cash utilized to fund an increase in our working capital, which primarily related to an increase in our trade accounts receivable.

Cash Flows from Investing Activities

During the six months ended November 30, 2011, cash used in investing activities was $18.2 million, a decrease of $2.6 million from the comparable period of fiscal 2011. Cash used in investing activities included our acquisition of four asset protection businesses for cash payments aggregating $10.7 million and $3.7 million utilized to fund an acquisition prior to November 30, 2011, but which did not close until after November 30, 2011.  Cash purchases of property, plant and equipment were $3.8 million and were primarily related to equipment used by our technicians.

During the six months ended November 30, 2010, cash used in investing activities was $20.8 million compared to $15.0 million from the comparable period of fiscal 2010. Cash used in investing activities included our acquisition of three asset protection businesses for cash payments aggregating $16.9 million.  Cash purchases of property, plant and equipment were $3.7 million and were primarily related to equipment used by our technicians, and land purchased for our new operations and training facility in Houston, Texas.

Cash Flows from Financing Activities

Net cash provided by financing activities was $12.3 million for the six months ended November 30, 2011, an increase of $10.0 million from the comparable period of fiscal 2011.  Net cash provided by financing activities related primarily to net  borrowings under our revolving credit facility of $19.0 million and proceeds of $1.3 million received from the exercise of stock options, offset by repayments of our capital lease obligations, long-term debt, and other short-term borrowings of $3.4 million, $2.8 million, $1.9 million,  respectively.

Net cash provided by financing activities was $2.3 million for the six months ended November 30, 2011, and related primarily to net borrowings under our revolving credit facility of $6.6 million and $2.1 million of other short-term borrowings offset by repayments of capital lease obligations and long-term debt of $3.0 million and $3.4 million, respectively.

Effect of Exchange Rate Changes on Cash and Cash Equivalents

The effect of exchange rate changes on our cash and cash equivalents was approximately ($0.1) million and $0.2 million for the six months ended November 30, 2011 and 2010, respectively.

31

Cash Balance and Credit Facility Borrowings

As of November 30, 2011, we had cash and cash equivalents totaling $5.3 million and available borrowing capacity of $28.3 million under our current revolving credit facility. As of November 30, 2011, there were outstanding borrowings of $22.8 million and a total of $3.9 million of outstanding letters of credit under the existing revolving credit facility. 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.

In December 2011, we entered into a Third Amended and Restated Credit Agreement (Credit Agreement), 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 Credit Agreement provides us with a $125.0 million revolving line of credit, which, under certain circumstances, can be increased to $150.0 million.  The Credit Agreement has a maturity date of December 20, 2016 and permits us to borrow up to $30.0 million in non-US dollar currencies and to use up to $10.0 million of the credit limit for the issuance of letters of credit.   Loans under the Credit Agreement bear interest at LIBOR or base rate, at our option, plus an applicable LIBOR margin ranging from 1% to 2%, or base rate margin ranging from -1.25% to -.25%, based upon our 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.  We have the benefit of the lowest margin if our 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 2.5 to 1.  We 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 if the Funded Debt Leverage Ratio exceeds 3.0 to 1.  The Credit Agreement is secured by liens on substantially all of our assets.

The Credit Agreement contains financial covenants requiring that we maintain a Funded Debt Leverage Ratio of less 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 us and our 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 our 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 our ability to acquire other businesses or companies except that the acquired business or company must be in our line of business, we 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 November 30, 2011, we were in compliance with the terms of the credit agreement in effect at that time, and we will continuously monitor our compliance with the new covenants contained in our new credit agreement.

Liquidity and Capital Resources Outlook

Future Sources of Cash

We expect our future sources of cash to include cash flow from operations, cash borrowed under our revolving credit facility and cash borrowed from leasing companies to purchase equipment and fleet service vehicles. Our revolving credit facility is available for cash advances required for working capital and for letters of credit to support our operations. To meet our short-and long-term liquidity requirements, we expect primarily to rely on cash generated from our operating activities and borrowings under our revolving credit facility. We are currently funding our acquisitions through our available cash, borrowings under our revolving credit facility and seller notes. We have an effective shelf registration statement with the SEC for the issuance of up to approximately $64.2 million of securities, including shares of common and preferred stock, debt securities, warrants and units. Accordingly, we may also obtain capital through the issuance of debt or equity securities, or a combination of both. As of December 31, 2011, there were outstanding borrowings of approximately $18.8 million and approximately $3.9 million of outstanding letters of credit under our revolving credit facility.

32

Future Uses of Cash

We expect our future uses of cash will primarily be for acquisitions, international expansion, purchases or manufacture of field testing equipment to support growth, additional investments in technology and software products and the replacement of existing assets and equipment used in our operations. We often make purchases to support new sources of revenues, particularly in our Services segment, but generally only do so with a high degree of certainty about related customer orders and pricing.  In addition, we have a certain amount of replacement equipment, including our fleet vehicles. We historically spend approximately 3% to 4% of our total revenues on capital expenditures, excluding acquisitions, and expect to fund these expenditures through a combination of cash and lease financing.

Our anticipated acquisitions may also require capital. We have completed seven acquisitions in fiscal 2012 with an initial cash outlay of $24.1 million, including three acquisitions completed in December 2011. In some cases, additional equipment will be needed to upgrade the capabilities of these acquired companies. In addition, our future acquisition and capital spending may increase as we aggressively pursue growth opportunities. Other investments in infrastructure, training and software may also be required to match our growth, but we plan to continue using a disciplined approach to building our business. In addition, we will use cash to fund our operating leases, capital leases and long-term debt repayments and various other obligations as they arise.

We also expect to use cash to support our working capital requirements for our operations, particularly in the event of further growth and due to the impacts of seasonality on our business. Our future working capital requirements will depend on many factors, including the rate of our revenue growth, our introduction of new solutions and enhancements to existing solutions and our expansion of sales and marketing and product development activities. To the extent that our cash and cash equivalents and future cash flows from operating activities are insufficient to fund our future activities, we may need to raise additional funds through bank credit arrangements or public or private equity or debt financings. We also may need to raise additional funds in the event we determine in the future to effect one or more acquisitions of businesses, technologies or products that will complement our existing operations. In the event additional funding is required, we may not be able to obtain bank credit arrangements or effect an equity or debt financing on terms acceptable to us or at all.

Off-balance Sheet Arrangements

During the six months ended November 30, 2011, 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.

ITEM 3.Quantitative and Qualitative Disclosures about Market Risk

Foreign Currency Risk

We have foreign currency exposure related to our operations in foreign locations where the functional currency is not the U.S. dollar. This foreign currency exposure, particularly the Euro, British Pound Sterling (GBP), Brazilian Real, Russian Ruble, Japanese Yen and the Indian Rupee, arises primarily from the translation of our foreign subsidiaries’ financial statements into U.S. dollars. For example, a portion of our annual sales and operating costs are denominated in GBP and we have exposure related to sales and operating costs increasing or decreasing based on changes in currency exchange rates. If the U.S. dollar increases in value against these foreign currencies, the value in U.S. dollars of the assets and liabilities originally recorded in these foreign currencies will decrease. Conversely, if the U.S. dollar decreases in value against these foreign currencies, the value in U.S. dollars of the assets and liabilities originally recorded in these foreign currencies will increase. Thus, increases and decreases in the value of the U.S. dollar relative to these foreign currencies have a direct impact on the value in U.S. dollars of our foreign currency denominated assets and liabilities, even if the value of these items has not changed in their original currency. For our foreign subsidiaries, assets and liabilities are translated at period ending rates of exchange. Translation adjustments for the assets and liability accounts are included in accumulated other comprehensive income in stockholders’ equity (deficit). We had approximately $1.4 million of foreign currency translation losses in other comprehensive income for the first six months of fiscal 2012. We do not currently enter into forward exchange contracts to hedge exposures to foreign currencies. We may consider entering into hedging or forward exchange contracts in the future.

33

Interest Rate Sensitivity

The interest rate on our revolving credit facility, currently 2.75%, is variable and adjusts periodically. As of November 30, 2011, there were outstanding borrowings of $22.8 million under our revolving credit facility.  A hypothetical 100 basis point adverse shift in interest rates would not have had a material effect on our results of operations for the three or six months ended November 30, 2011.

From time to time, we enter into interest rate swap contracts whereby we would receive or pay an amount equal to the difference between a fixed rate and LIBOR on a quarterly basis in order to reduce our potential exposure to interest rate fluctuations. All gains and losses are recognized as an adjustment to interest expense and the combined fair values are recorded in other liabilities on the consolidated balance sheet. As of November 30, 2011, we had no such contracts in effect.

We had cash and cash equivalents of $5.3 million as of November 30, 2011. These amounts are held for working capital purposes and were invested primarily bank deposits, money market funds and short-term, interest-bearing, investment-grade securities. Due to the short-term nature of these investments, we believe that we do not have any material exposure to changes in the fair value of our investment portfolio as a result of changes in interest rates. Declines in interest rates, however, will reduce future investment income.

Fair Value of Financial Instruments

We do not believe that we have material exposure to market risk with respect to investments, as our investments consist primarily of highly liquid investments purchased with a remaining maturity of three months or less. We do not use derivative financial instruments for speculative or trading purposes; however, this does not preclude our adoption of specific hedging strategies in the future.

ITEM 4.Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of November 30, 2011, the Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and the Company’s Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures, as such term is defined in Rule 13a-15(e). Based on the evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures are effective to ensure that information required to be disclosed by the Company in the reports it files or submits under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms.

Changes in Internal Control Over Financial Reporting

There has been no change in the Company’s internal control over financial reporting that occurred during the Company’s quarter ended November 30, 2011 that has materially affected, or is reasonably likely to materially affect, such internal control over financial reporting. Internal control over financial reporting at the Company was excluded from the evaluation for the quarter ended November 30, 2011.

Common Stock

In May 2011, the Company completed a secondary offering of 3,754,061 shares of common stock at a price of $16.00 per share.  The Company sold 989,660 shares and 2,764,401 shares were sold by a selling stockholder.  The Company received net proceeds of approximately $14.7 million from the offering. The Company used the net proceeds for general corporate purposes including the reduction of outstanding indebtedness, acquisitions, capital expenditures and working capital.

Dividends on common stock will be paid when, and if declared by the board of directors. Each holder of common stock is entitled to vote on all matters and is entitled to one vote for each share held.

Equity Awards

In September 2009, the Company’s board of directors and shareholders adopted and approved the 2009 Long-Term Incentive Plan (the 2009 Plan), which became effective upon the closing of the IPO. Awards may be in the form of stock options, restricted stock units and other forms of stock-based incentives, including stock appreciation rights and deferred stock rights. The term of each incentive and non-qualified stock option is ten years. Vesting generally occurs over a period of four years, the expense for which is recorded on a straight-line basis over the requisite service period. The 2009 Plan allows for the grant of awards of up to approximately 2,286,000 shares of common stock, of which 1,700,000 shares were available for future grants as of November 30, 2011. Prior to the Company’s IPO in October 2009, the Company had two stock option plans: (i) the 1995 Incentive Stock Option and Restricted Stock Purchase Plan (the 1995 Plan), and (ii) the 2007 Stock Option Plan (the 2007 Plan). No additional awards may be granted from these two plans. As of November 30, 2011, there were approximately 2,665,000 stock options outstanding and approximately 449,000 unvested restricted stock units outstanding under the 2009 Plan, the 2007 Plan, and the 1995 Plan.

The fair value of the Company’s stock option awards for the six months ended November 30, 2010 was estimated at the date of grant using the Black-Scholes option-pricing model with the range of assumptions below.  No stock options were granted during the six months ended November 30, 2011.

	Six months ended November 30, 2010
Dividend yield	0.0	%
Expected volatility	44	%
Risk-free interest rate	2.6	%
Expected term (years)	6.3

The Company recognized stock-based compensation expense related to stock option awards of approximately $0.9 million for each of the three month periods ended November 30, 2011 and 2010. For the six months ended November 30, 2011 and 2010, the Company recognized stock-based compensation expense related to stock option awards of $1.7 million and $1.6 million, respectively.  As of November 30, 2011, there was approximately $5.3 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 1.7 years.  Cash proceeds from and the aggregate intrinsic value of stock options exercised during the three and six months ended November 30, 2011 and 2010 were as follows:

	Three months ended November 30,				Six months ended November 30,
	2011		2010		2011		2010
Cash proceeds from options exercised	$	1,268	$	—	$	1,325	$	—
Aggregate intrinsic value of options exercised	$	3,026	$	—	$	3,062	$	—

The Company also recognized approximately $0.5 million and $0.1 million in stock-based compensation expense related to restricted stock unit awards during the three months ended November 30, 2011 and 2010, respectively.  For the six months ended November 30, 2011 and 2010, the Company recognized stock-based compensation expense related to restricted stock unit awards of $0.7 million and $0.2 million, respectively.  As of November, 2011, there was approximately $6.6 million of unrecognized compensation costs, net of estimated forfeitures, related to restricted stock unit awards, which are expected to be recognized over a remaining weighted average period of 3.5 years.

In October 2011, the Company granted approximately 9,000 shares of fully-vested common stock to its five non-employee directors, in connection with its non-employee director compensation plan.  These shares had a grant date fair value of approximately $0.2 million, which was recorded as stock-based compensation expense during the three and six months ended November 30, 2011.

During the six months ended November 30, 2011, approximately 52,000 restricted stock units vested, the fair value of which was $0.5 million. Upon vesting, restricted stock units are generally net share-settled to cover the required withholding tax and the remaining amount is converted into an equivalent number of shares of common stock. The restricted stock units that vested in the first six months of fiscal 2012 were net-share settled such that the Company withheld shares with value equivalent to the employees’ minimum statutory obligation for the applicable income and other employment taxes, and remitted the cash to the appropriate taxing authorities. The Company withheld approximately 16,000 shares based on the value of the restricted stock units on their vesting date as determined by the Company’s closing stock price. Total payments for the employees’ tax obligations to the taxing authorities were $0.3 million and are reflected as a financing activity within the consolidated statements of cash flows. These net-share settlements had the effect of share repurchases by the Company as they reduced and retired the number of shares that would have otherwise been issued as a result of the vesting and did not represent an expense to the Company.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Revenue Recognition

Revenue recognition policies for the various sources of revenues are as follows:

Services

The Company predominantly derives revenues by providing its services on a time and material basis and recognizes revenues when services are rendered. At the end of any reporting period, there may be earned but unbilled revenues that are accrued. Payments received in advance of revenue recognition are reflected as deferred revenues.

Software

Revenues from the sale of perpetual licenses are recognized upon the delivery and acceptance of the software. Revenues from term licenses are recognized ratably over the period of the license. Revenues from maintenance, unspecified upgrades and technical support are recognized ratably over the period such items are delivered. For multiple-element arrangement software contracts that include non-software elements, and where the software is essential to the functionality of the non-software elements (collectively referred to as software multiple-element arrangements), the Company applies the rules as noted below.

Products

Revenues from product sales are recognized when risk of loss and title passes to the customer. The exceptions to this accounting treatment would be for multiple-element arrangements (described below) or those situations where specialized installation or customer acceptance is required. Payments received in advance of revenue recognition are reflected as deferred revenues.

Percentage of Completion

A portion of the Company’s revenues are generated from engineering and manufacturing of custom products under long-term contracts that may last from several months to several years, depending on the contract. Revenues from long-term contracts are recognized on the percentage-of-completion method of accounting. Under the percentage-of-completion method of accounting revenues are recognized as work is performed. The percentage of completion at any point in time is based on total costs or total labor dollars incurred to date in relation to the total estimated costs or total labor dollars estimated at completion. The percentage of completion is then applied to the total contract revenue to determine the amount of revenue to be recognized in the period. Application of the percentage-of-completion method of accounting requires the use of estimates of costs to be incurred for the performance of the contract. Contract costs include all direct materials, direct labor costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs, and all costs associated with operation of equipment. The cost estimation process is based upon the professional knowledge and experience of the Company’s engineers, project managers and financial professionals. Factors that are considered in estimating the work to be completed include the availability and productivity of labor, the nature and complexity of the work to be performed, the effect of change orders, the availability of materials, the effect of any delays in our project performance and the recoverability of any claims. Whenever revisions of estimated contract costs and 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.

Multiple-element Arrangements

The Company occasionally enters into transactions that represent multiple-element arrangements, which may include any combination of services, software, and hardware. When a sales arrangement contains multiple elements, such as hardware and services and/or software products, the Company allocates revenue to each element based on a selling price hierarchy. The selling price for a deliverable is based on its vendor specific objective evidence (VSOE) if available, third party evidence (TPE) if VSOE is not available, or estimated selling price (ESP) if neither VSOE nor TPE is available.  The Company has historically utilized the VSOE due to the nature of its products. In multiple element arrangements where more-than-incidental software deliverables are included, revenue is allocated to each separate unit of accounting for each of the non-software deliverables and to the software deliverables as a group using the relative selling prices of each of the deliverables in the arrangement based on the aforementioned selling price hierarchy. If the arrangement contains more than one software deliverable, the arrangement consideration allocated to the software deliverables as a group is then allocated to each software deliverable using the guidance for recognizing software revenue, as amended.

Use of Estimates

These unaudited consolidated financial statements have been prepared in conformity with GAAP, which requires management to make estimates and assumptions about future events that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. The more significant estimates include valuation of goodwill and intangible assets, useful lives of long-lived assets, acquisition-related contingent consideration, allowance for doubtful accounts, inventory valuation, reserves for self-insured workers compensation and health benefits and provision for income taxes.

Goodwill and Intangible Assets

Goodwill represents the excess of the purchase price over the fair market value of net assets of the acquired business at the date of acquisition. The Company tests for impairment annually, in its fiscal fourth quarter, using a two-step process. The first step identifies potential impairment by comparing the fair value of the Company’s reporting units to its carrying value. If the fair value is less than the carrying value, the second step measures the amount of impairment, if any. The impairment loss is the amount by which the carrying amount of goodwill exceeds the implied fair value of that goodwill. The most recent annual test for impairment performed for fiscal 2011 did not identify any instances of impairment and there were no events through November 30, 2011 that warranted a reconsideration of our impairment test results.

Intangible assets are recorded at cost. Intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and accounts receivable. At times, cash deposits may exceed the limits insured by the Federal Deposit Insurance Corporation. The Company believes it is not exposed to any significant credit risk or risk of nonperformance of financial institutions.

The Company sells primarily to large companies, extends reasonably short collection terms, performs credit evaluations and does not require collateral. The Company maintains reserves for potential credit losses.

We have one customer, BP plc. (BP), which accounted for 17% and 15% of revenues for the three months ended November 30, 2011 and 2010, respectively, and 16% of revenues for each of the six month periods ended November 30, 2011 and 2010.  Accounts receivable from this customer were approximately 13% and 15% of total accounts receivable, net as of November 30, 2011 and May 31, 2011, respectively. Our relationship with BP is comprised of separate contracts for non-destructive testing and inspection services with multiple affiliated entities within the broad BP organization.  We conduct business with various divisions or affiliates of the BP organization through numerous contracts covering many segments of BP’s business including downstream (refinery), midstream (pipelines) and upstream (exploration).  These contracts are typically negotiated locally with the specific BP division or affiliate, are of varying lengths, have different start and end dates and differ in terms of the scope of work and nature of services provided.  Most contracts are based on time and materials.

Equity-based Compensation

The Company measures the cost of employee services received in exchange for an award of equity instruments based upon the grant-date fair value of the award. The Company uses the “straight-line” attribution method for allocating compensation costs and recognizes the fair value of each equity award on a straight-line basis over the vesting period of the related awards.

The Company uses the Black-Scholes option-pricing model to estimate the fair value of the stock option awards as of the grant date. The Black-Scholes model, by its design, is highly complex and dependent upon key data inputs estimated by management. The primary data inputs with the greatest degree of judgment are the expected term of stock option awards and the estimated volatility of the Company’s common stock price. The Black-Scholes model is sensitive to changes in these two variables.  Since the Company’s initial public offering (IPO), the expected term of the Company’s stock options is generally determined using the mid-point between the vesting period and the end of the contractual term. Expected stock price volatility is typically based on the daily historical trading data for a period equal to the expected term. Because the Company’s historical trading data only dates back to October 8, 2009, the first trading date after its IPO, the Company has estimated expected volatility using an analysis of the stock price volatility of comparable peer companies.  Prior to the Company’s IPO, the exercise price equaled the estimated fair market value of the Company’s common stock, as determined by its board of directors. Since the Company’s IPO, the exercise price of stock option grants is determined using the closing market price of the Company’s common stock on the date of grant.

Recent Accounting Pronouncements

In October 2009, the FASB issued ASU 2009-13, Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements (a consensus of the FASB Emerging Issues Task Force), which requires companies to allocate the overall consideration in multiple-element arrangements to each deliverable by using a best estimate of the selling price of individual deliverables in the arrangement in the absence of vendor-specific objective evidence or other third-party evidence of the selling price. Effective June 1, 2011, the Company adopted, on a prospective basis, the provisions of this updated accounting standard related to revenue recognition associated with contractual arrangements involving multiple elements. The adoption of this pronouncement did not have a material impact on the Company’s consolidated financial statements.

In April 2010, the FASB issued ASU 2010-17, Revenue Recognition—Milestone Method (Topic 605): Milestone Method of Revenue Recognition (a consensus of the FASB Emerging Issues Task Force).  ASU 2010-17 provides guidance on applying the milestone method to milestone payments for achieving specified performance measure when those payments are related to uncertain future events limited to transactions involving research and development. Entities can make an accounting policy election to recognize arrangement consideration received for achieving specified performance measures during the period in which the milestones are achieved, provided certain criteria are met. Effective June 1, 2011, the Company adopted, on a prospective basis, the provisions of this updated accounting standard related to milestones. The adoption of this pronouncement did not have a material impact on the Company’s consolidated financial statements.

In June 2011, the FASB issued ASU 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. ASU 2011-05 allows an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. This authoritative guidance eliminates the option to present the components of other comprehensive income as part of the statement of equity. ASU 2011-05 does not change the items that must be reported in other comprehensive income, when an item of other comprehensive income must be reclassified to net income, the Company’s option to present components of other comprehensive income either net of related tax effects or before related tax effects, nor does it affect how earnings per share is calculated or presented. ASU 2011-05 requires retrospective application, and it is effective for fiscal years and interim periods within those years, beginning after December 15, 2011.  Early adoption is permitted. The Company does not expect that the adoption of this pronouncement will have a material impact on the Company’s consolidated financial statements.

In September 2011, the FASB issued Accounting Standards Update (ASU) 2011-08, Intangibles-Goodwill and Other (Topic 350): Testing Goodwill for Impairment.  ASU 2011-08 permits an entity to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that this is the case, it is then necessary to perform the currently prescribed two-step goodwill impairment test. Otherwise, the two-step goodwill impairment test is not required. ASU 2011-08 is effective for the Company in fiscal 2013 and earlier adoption is permitted. The Company does not expect that the adoption of this pronouncement will have a material impact on the Company’s consolidated financial statements.

1. Description of Business & 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. Given the role our services play in ensuring the safe and efficient operation of infrastructure, the Company has historically provided a majority of its services to its customers on a regular, recurring basis. 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, aerospace and defense, transportation, primary metals and metalworking, pharmaceuticals and food processing industries.

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair statement have been included. Operating results for the three and six months ended November 30, 2011 are not necessarily indicative of the results that may be expected for the year ending May 31, 2012. The balance sheet at May 31, 2011 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements. You should read these unaudited consolidated financial statements together with the historical consolidated financial statements of the Company as filed with the Securities and Exchange Commission.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Mistras Group, Inc. and its wholly or majority-owned subsidiaries. Where 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 interest in net income, net of tax, is classified separately in the accompanying consolidated statements of operations.

All significant intercompany accounts and transactions have been eliminated in consolidation. All foreign subsidiaries’ fiscal years end on April 30, while Mistras Group, Inc. and the domestic subsidiaries’ fiscal years end on May 31. The effect of this difference in timing of reporting foreign operations on the consolidated results of operations and consolidated financial position is not significant.

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.

Revision of Prior Period Financial Statements

We have revised our consolidated statement of cash flows for the six months ended November 30, 2010 to reflect the cash flows associated with the financing of an insurance premium as cash flows from financing activities.  Such cash flows were previously reported in operating activities.  A summary of the revisions to the consolidated statements of cash flows for the six months ended November 30, 2010 is as follows:

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.

The Company was a defendant in two related purported class action lawsuits in California, based upon alleged violations of California labor and employment law: Quiroz v. Mistras Group, Inc., et al, U.S. District Court, Central District of California (Case No. CV09-7146 PSG), filed in September 2009, and Ballard v. Mistras Group, Inc., et al, U.S. District Court, Central District of California (Case No. 2:10-cv-03186 (PSG)), filed in March 2010.  The settlement for these cases received final court approval in August 2011.  The Company took a charge during the three month and six month periods ending November 30, 2010 of $0.4 million and $0.1 million, respectively, for these cases.

Acquisition-related contingencies

The Company is liable for contingent consideration in connection with certain of its acquisitions. As of November 30, 2011, total potential acquisition-related contingent consideration ranged from $0 to $10.1 million and would be payable upon the achievement of specific performance metrics by certain of the acquired companies over the next four years of operations. See Note 5 to these consolidated financial statements for further discussion of the Company’s acquisitions.

In December 2011, the Company entered into a Third Amended and Restated Credit Agreement (Credit Agreement) 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 Credit Agreement provides the Company with a $125.0 million revolving line of credit, which, under certain circumstances, can be increased to $150.0 million.  The Credit Agreement has a maturity date of December 20, 2016 and permits the Company to borrow up to $30.0 million in non-U.S. dollar currencies and to use up to $10.0 million of the credit limit for the issuance of letters of credit.    See Note 10 to these consolidated financial statements for further discussion of the Company’s Credit Agreement.

In December 2011, the Company completed the acquisition of three asset protection businesses to continue its strategic efforts in market expansion. Prior to November 30, 2011, the Company funded an escrow account in the amount of $3.7 million for one of the acquisitions. These disbursed funds were classified as restricted cash on the consolidated balance sheet as of November 30, 2011. The Company’s cash outlay for the remaining two acquisitions was approximately $9.6 million and was made subsequent to November 30, 2011. 

In addition to the cash consideration, the agreement allows for contingent consideration to be earned based upon certain of the acquired companies reaching specific performance metrics over the next three years of operation. The Company is in the process of completing the preliminary purchase price allocation. These acquisitions were not individually significant and no pro forma information has been included.

5. Acquisitions

The Company made four acquisitions during the six months ended November 30, 2011. These acquisitions were asset protection companies specializing in advanced ultrasonic inspection, NDT services and inspection, ultrasonic testing (UT) products and systems, and in-house component inspection. These companies were acquired to complement our service and product offerings within our Services, Products and Systems, and International segments. One acquisition was an asset purchases that met the definition of “acquisitions of businesses” under the provision of FASB Accounting Standards Codification (ASC) 805-10-20, and has been integrated into our Services segment. In the three remaining acquisitions, we acquired 100% of the common stock of the acquirees, all of which have been integrated into our International segment. In addition to the cash and debt consideration related to acquisitions closed during the six months ended November 30, 2011, the Company also accrued a liability of approximately $0.8 million as of November 30, 2011, which represents the estimated fair value of contingent consideration expected to be payable in the event that certain of the acquired companies achieve specific performance metrics over the next four years of operations. The total potential contingent consideration ranges from zero to $0.9 million for these acquisitions.

Assets and liabilities of the acquired businesses were included in the consolidated balance sheets as of November 30, 2011 based on their estimated fair value on the date of acquisition as determined in a purchase price allocation, using available information and making assumptions management believes are reasonable. The Company is still in the process of completing its valuations of the intangible assets of the acquisitions in our International segment. We believe we will have finalized these valuations and purchase price allocations prior to the end of our third fiscal quarter ending February 29, 2012. The Company’s preliminary allocation of purchase price for these acquisitions is included in the table below. Results of operations for the period from acquisition date are reported in each respective operating segment’s statement of operations. The following table summarizes the estimated fair value of the assets acquired and liabilities assumed at the date of acquisition:

	Six months ended November 30,

Goodwill	7,888		7,129
Less: noncontrolling interest	—		(117		)
Net assets acquired	$	15,532	$	19,538

The amortization period of intangible assets acquired ranges from one to fifteen years. The Company recorded approximately $7.9 million of goodwill in connection with its fiscal 2012 acquisitions, reflecting the strategic fit and revenue and earnings growth potential of these businesses. Substantially all of the goodwill recognized is expected to be deductible for tax purposes.

Revenues included in the consolidated statement of operations for the three and six months ended November 30, 2011 from these acquisitions for the period subsequent to the closing of each transaction was approximately $1.9 million and $2.3 million, respectively. Loss from operations included in the consolidated statement of operations for the three and six months ended November 30, 2011 from these acquisitions for the period subsequent to the closing of each transaction was approximately ($11) thousand and ($67) thousand, respectively.

The unaudited pro forma information for the periods set forth below gives effect to the fiscal 2012 acquisitions as if they had occurred at the beginning of each period presented. The pro forma information is presented for informational purposes only and is not necessarily indicative of the results of operations that actually would have been achieved had the acquisitions been consummated as of that time (unaudited, in thousands):

	Three months ended November 30,				Six months ended November 30,
	2011		2010		2011		2010
Revenues	$	119,503	$	94,270	$	216,297	$	168,139
Income from operations	$	14,244	$	10,073	$	19,947	$	12,925

During the three and six month periods ended November 30, 2011, the Company adjusted the fair value of certain acquisition-related contingent consideration liabilities. The adjustments resulted in a net decrease of $0.7 million to the Company’s acquisition-related contingent consideration liabilities, which were approximately $4.8 million as of November 30, 2011 and recorded on the balance sheet in accrued expenses and other liabilities. These adjustments also resulted in a corresponding net increase to income from operations of $0.7 million. Additionally, the Company incurred certain acquisition-related costs of $0.4 million in connection with due diligence, professional fees, and other expenses for its fiscal 2012 acquisition activity. Both the fair value adjustments to acquisition-related contingent consideration liabilities and the acquisition-related expenses have been classified as acquisition-related costs in the statement of operations for the three and six months ended November 30, 2011. Acquisition-related costs for the Company’s fiscal 2011 acquisition activity were insignificant for the three and six months ended November 30, 2010.

Prior to November 30, 2011, the Company funded an escrow account in the amount of $3.7 million related to an acquisition that closed December 6, 2011. These disbursed funds have been classified as restricted cash on the consolidated balance sheet and included in cash used in investing activities on the statement of cash flows for the six months ended November 30, 2011.

13. Segment Disclosure

The Company’s three segments are:

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

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.

International. This segment offers services, products and systems similar to those of our 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 our Products and Systems segment.

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.

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 stock-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.

Selected consolidated financial information by segment for the periods shown was as follows:

Senior Credit Facility

In July 2009, the Company entered into a Second Amended and Restated Credit Agreement with Bank of America, N.A., JPMorgan Chase Bank, N.A., TD Bank, N.A. and Capital One, N.A., which provided for a $25.0 million term loan and a $55.0 million secured revolving credit facility. The outstanding principal balance of the term loan was subsequently repaid in October 2009 in connection with the Company’s IPO and may not be re-borrowed under the current credit agreement. The Company also repaid the outstanding balance of the revolving credit facility but may re-borrow under the revolving credit facility at any time during the term of the agreement. As of November 30, 2011, there were outstanding borrowings of $22.8 million and a total of $3.9 million of outstanding letters of credit under the existing revolving credit facility.

In December 2011, the Company entered into a Third Amended and Restated Credit Agreement (Credit Agreement) 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 Credit Agreement provides the Company with a $125.0 million revolving line of credit, which, under certain circumstances, can be increased to $150.0 million.  The Credit Agreement has a maturity date of December 20, 2016 and permits the Company to borrow up to $30.0 million in non-U.S. dollar currencies and to use up to $10.0 million of the credit limit for the issuance of letters of credit.   Loans under the Credit Agreement bear interest at LIBOR or base rate, at the option of the Company, plus an applicable LIBOR margin ranging from 1% to 2%, or base rate margin ranging from -1.25% to -.25%, based upon its 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 2.5 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 if the Funded Debt Leverage Ratio exceeds 3.0 to 1.  The Credit Agreement is secured by liens on substantially all of the assets of the Company.

The Credit Agreement contains financial covenants requiring that the Company maintain a Funded Debt Leverage Ratio of less 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 its 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.

In December 2011, outstanding borrowings under the former credit agreement were repaid in full using proceeds from the Credit Agreement.

Notes Payable and Other

In connection with acquisitions the Company has completed, it has, at various times, issued subordinated notes payable to the sellers. The maturity of these notes range from three to five years from the date of acquisition with interest rates ranging from 0% to 7%. The Company has discounted these obligations to reflect a 3.5% to 10% imputed interest rate. Unamortized discount on these notes totaled approximately $0.1 million as of November 30, 2011 and May 31, 2011. Amortization is recorded as interest expense in the consolidated statement of operations. The Company also has payment obligations to the sellers or the shareholders of the sellers pursuant to non-compete agreements which require the sellers and shareholders of the sellers not to compete with the Company.  The payment obligations under these agreement s range from 3 to 5 years.

Earnings per Share

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 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:
