Item 2.02. Results of Operations and Financial Condition

On October 10, 2011, Mistras Group, Inc. (the “Company,” “we” or “us”) issued a press release announcing the financial results for its first quarter of fiscal year 2012, which ended August 31, 2011. A copy of the press release is attached as Exhibit 99.1 to this report.

Disclosure of Non-GAAP Financial Measures

In the press release attached, the Company uses the term “Adjusted EBITDA,” which is not a measurement of financial performance under U.S. generally accepted accounting principles (“GAAP”). “Adjusted EBITDA” is defined as net income plus: interest expense, provision for income taxes, depreciation and amortization, stock-based compensation expense, and, as applicable, certain acquisition related costs and certain one-time and generally non-recurring items (which items are described or listed in the reconciliation table included in the press release).

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 which is used determine incentive compensation for executives and employees.

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.
