Known material factors that could cause actual results to differ materially from those in the forward-looking statements include, but are not limited to, risks associated with the following: risks and uncertainties associated with the Chapter 11 Proceeding, including our ability to develop, confirm and consummate the Restructuring Plan or an alternative plan under Chapter 11 or alternative restructuring transaction, including a sale of all or substantially all of our assets, which may be necessary to continue as a going concern, ability to maintain relationships with suppliers, customers, employees and other third parties as a result of our Chapter 11 Proceeding, our ability to obtain the approval with respect to motions or other requests made to the Bankruptcy Court in our Chapter 11 Proceeding, including maintaining strategic control as debtors-in-possession, our ability to obtain sufficient financing to allow us to emerge from the Chapter 11 Proceeding and execute our business plan post-emergence, failure to satisfy our short- or long-term liquidity needs, including our inability to generate sufficient cash flow from operations or to obtain adequate financing to fund our capital expenditures and meet working capital needs, the effects of the Chapter 11 Proceeding on the Company and on the interests of our various constituents, including holders of our common shares, Bankruptcy Court rulings in the Chapter 11 Proceeding as well as the outcome of all other pending litigation and the outcome of the Chapter 11 Proceeding in general, the length of time that the Company will operate under Chapter 11 protection and the continued availability of operating capital during the pendency of the Chapter 11 Proceeding, risks associated with third party motions in the Chapter 11 Proceeding, which may interfere with our ability to confirm and consummate a plan of reorganization, the potential adverse effects of the Chapter 11 Proceeding on our liquidity and results of operations, increased advisory costs to execute a reorganization, the impact of the New York Stock Exchange's delisting of our common shares on the liquidity and market price of our common shares and on our ability to access the public capital markets, a decline in demand for our services, including due to declining commodity prices, overcapacity and other competitive factors affecting our industry, the cyclical nature and volatility of the oil and gas industry, which impacts the level of exploration, production and development activity and spending patterns by the oil and gas industry, a decline in, or substantial volatility of, crude oil and gas commodity prices, which generally leads to decreased spending by our customers and negatively impacts drilling, completion and production activity and therefore impacts demand and pricing for our services, which negatively impacts our results of operations, including potentially resulting in impairment charges, pressure on pricing for our core services, including due to competition and industry and/or economic conditions, which may impact, among other things, our ability to implement price increases or maintain pricing on our core services, the loss of, or interruption or delay in operations by, one or more significant customers, the failure to pay amounts when due, or at all, by one or more significant customers, changes in customer requirements in markets or industries we serve, costs, delays, regulatory compliance requirements and other difficulties in executing our long-term growth strategy, including those related to expansion into new geographic regions and new business lines, the effects of future acquisitions on our business, including our ability to successfully integrate our operations and the costs incurred in doing so, business growth outpacing the capabilities of our infrastructure, adverse weather conditions in oil or gas producing regions, the effect of environmental and other governmental regulations on our operations, including the risk that future changes in the regulation of hydraulic fracturing could reduce or eliminate demand for our hydraulic fracturing services, the incurrence of significant costs and liabilities resulting from litigation, the incurrence of significant costs and liabilities resulting from our failure to comply, or our compliance with, new or existing environmental regulations or an accidental release of hazardous substances into the environment, expanding our operations overseas, the loss of, or inability to attract key management personnel, a shortage of qualified workers, the loss of, or interruption or delay in operations by, one or more of our key suppliers, operating hazards inherent in our industry, including the significant possibility of accidents resulting in personal injury or death, property damage or environmental damage, and accidental damage to or malfunction of equipment. The foregoing list of factors is not exclusive.

All subsequent written or oral forward-looking statements concerning C&J are expressly qualified in their entirety by the cautionary statements above. Readers are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date hereof. We undertake no obligation to publicly update or revise any forward-looking statements after the date they are made, whether as a result of new information, future events or otherwise, except as required by law. EBITDA is defined as earnings before net interest expense, income taxes, depreciation and amortization. Adjusted EBITDA is defined as earnings before net interest expense, income taxes, depreciation and amortization, net gain or loss on disposal of assets, transaction costs and certain non-routine items. EBITDA and Adjusted EBITDA are non-GAAP financial measures, and when analyzing C&J’s operating performance, investors should use EBITDA and Adjusted EBITDA in addition to, and not as an alternative for, operating income and net income (loss) (each as determined in accordance with U.S. GAAP). C&J Management uses EBITDA and Adjusted EBITDA as supplemental financial measures because we believe they are useful indicators of our performance.
