Complete Production Services, Inc. Reports First Quarter 2011 Earnings of $0.50 Per Diluted Share

Houston—(Business Wire)—April 21, 2011—Complete Production Services, Inc. (NYSE: CPX) today reported first quarter revenue of $495.2 million, Adjusted EBITDA (as defined below) of $125.4 million, operating income of $76.2 million and net income of $38.9 million, or $0.50 per diluted share.

“Our results were solid overall during the first quarter of 2011,” commented Joe Winkler, Chairman and Chief Executive Officer. “Excellent results in all of our major regions during the month of March and strong performance throughout the quarter in certain geographic areas more than offset challenging weather conditions in other regions. Activity in North Texas and Western Oklahoma, which typically account for approximately one-third of our revenue, was significantly impacted by poor weather conditions during the first two weeks of February, and North Dakota was affected throughout the quarter.”

Revenue for the Completion and Production Services segment during the first quarter of 2011 was $437.1 million, an increase of $20.5 million over the prior quarter. Results for our fluid management, coiled tubing and pressure pumping businesses accounted for the majority of the increase in revenue. Adjusted EBITDA for the segment was $121.5 million in the first quarter of 2011, up $2.3 million compared to the fourth quarter of 2010. The segment benefited from increasing activity in service intensive oil and liquid-rich plays, as well as the deployment of our second frac fleet in the Eagle Ford Shale, partially offset by the impact of challenging weather conditions during the first quarter of 2011.

Drilling Services segment revenue was $50.2 million during the first quarter of 2011, compared to $48.7 million during the fourth quarter of 2010. Adjusted EBITDA for the segment increased $0.5 million from the prior quarter to $12.5 million during the first quarter of 2011. The segment was positively impacted by increased activity in our rig logistics business and lower repair and maintenance costs in our contract drilling operations.

In comparison to the first quarter of 2010, consolidated revenue increased $185.5 million, or 60%, Adjusted EBITDA increased $69.5 million, operating income increased $65.7 million, and net income increased by $41.7 million, or $0.53 per diluted share.

“We achieved record results in March as increased demand for all of our major services resulted in greater utilization, revenue and earnings. Activity levels in the long-lateral service intensive wells within oil and liquid-rich plays continue to increase driving additional demand for quality completion services. To address our customers’ growing needs, we expect to deploy a 50,000 hydraulic horsepower frac spread in the Eagle Ford Shale, our third fleet in the region, and three large diameter extended reach coil tubing units during the second quarter of 2011,” concluded Mr. Winkler.

Complete Production Services, Inc. is a leading oilfield service provider focused on the completion and production phases of oil and gas wells. The company has established a significant presence in unconventional oil and gas plays in North America that it believes have the highest potential for long-term growth.

Such statements are based on current expectations and entail various risks and uncertainties that could cause actual results to differ materially from those forward-looking statements. Such risks and uncertainties include, among other things, risks associated with the general nature of the oilfield service industry, the uncertainty of near-term and long-term activity levels, general economic conditions in the United States and globally, and other risks described in the company’s most recent annual report on Form 10-K and subsequent quarterly reports on Form 10-Q.

Management evaluates the performance of Complete’s operating segments using non-GAAP financial measures, including Adjusted EBITDA. Adjusted EBITDA is calculated as net income from continuing operations before net interest expense, taxes, depreciation, amortization, impairment charges and non-controlling interest. Adjusted EBITDA is not a substitute for GAAP measures of earnings and cash flow.
