Important Disclosures Non-GAAP Measures This presentation includes references to EBITDA, Adjusted EBITDA and EBIT, which are not measures calculated in accordance with accounting principles generally accepted in the United States of America (“GAAP”). A reconciliation of EBITDA, Adjusted EBITDA and EBIT to net income, the most directly comparable measure calculated in accordance with GAAP, is provided in the Appendix included in this presentation. While management believes such measures are useful for investors, these measures should not be used as a replacement for financial measures that are calculated in accordance with GAAP. Forward-Looking Statements The information in this presentation includes “forward-looking statements.” All statements, other than statements of historical fact included in this presentation, regarding our strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management are forward-looking statements. When used in this presentation, the words “could,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “project” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words.

These forward-looking statements are based on management’s current belief, based on currently available information, as to the outcome and timing of future events. Forward-looking statements may include statements about: demand for our products and services, which is affected by, among other things, changes in the price of, and demand for, crude oil and natural gas in domestic and international markets; the level of growth in the number of rigs and well count; the level of fracturing activity and the availability of fracturing equipment and pressure pumping services; the size and timing of orders; availability of raw materials; expectations regarding raw materials, overhead and operating costs and margins; availability of skilled and qualified workers; potential liabilities arising out of the installation, use or misuse of our products; the possibility of cancellation of orders; our business strategy; our financial strategy, operating cash flows, liquidity and capital required for our business; our future revenue, income and operating performance; the termination of relationships with major customers or suppliers; warranty and product liability claims; laws and regulations, including environmental regulations, that may increase our costs, limit the demand for our products and services or restrict our operations; disruptions in the political, regulatory, economic and social conditions domestically or internationally; increased import tariffs assessed on products from China or imported raw materials used in the manufacture of our goods in the United States; a failure of our information technology infrastructure or any significant breach of security; potential uninsured claims and litigation against us; our dependence on the continuing services of certain of our key managers and employees; and plans, objectives, expectations and intentions contained in this presentation that are not historical. You are cautioned not to place undue reliance on any forward-looking statements, which speak only as of the date of this presentation.

There was no early extinguishment of debt in 2014. Stock-based compensation was $1.3 million in 2014. Adjusted EBITDA was equal to $90.1 million. Important Disclosure Regarding Non-GAAP Measures EBITDA and Adjusted EBITDA are not measures calculated in accordance with GAAP. EBITDA and Adjusted EBITDA are supplemental non-GAAP financial measures that are used by management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies. We define EBITDA as net income excluding net interest expense, income tax and depreciation and amortization. We define Adjusted EBITDA as EBITDA excluding (gain) loss on debt extinguishment and stock-based compensation. Our management believes EBITDA and Adjusted EBITDA are useful, because they allow management to more effectively evaluate our operating performance and compare the results of our operations from period to period without regard to financing methods or capital structure, or other items that impact comparability of financial results from period to period. EBITDA and Adjusted EBITDA should not be considered as alternatives to, or more meaningful than, net income or any other measure as determined in accordance with GAAP. Our computations of EBITDA and Adjusted EBITDA may not be comparable to other similarly titled measures of other companies. We present EBITDA and Adjusted EBITDA, because we believe they provide useful information regarding the factors and trends affecting our business. 24
