Complete Production Services, Inc. Reports Second Quarter Earnings of $0.20 Per Diluted Share

Houston—(Business Wire)—July 21, 2010—Complete Production Services, Inc. (NYSE: CPX) today reported second quarter revenue of $360.2 million, an increase of 16% over the first quarter of 2010, Adjusted EBITDA (as defined below) of $85.3 million, an increase of 53% over the first quarter of 2010, operating income of $39.9 million and net income of $15.7 million, or $0.20 per diluted share. Cash balance increased to $141.6 million as of the second quarter, and the company’s $240 million credit facility remains undrawn.

Revenue for the Completion and Production Services segment during the second quarter of 2010 was $310.5 million, an increase of 17% over the prior quarter. Adjusted EBITDA for the segment was $84.7 million in the second quarter of 2010, up 47% versus the first quarter of 2010. Adjusted EBITDA margin was 27.3% during the second quarter of 2010 versus 21.7% for the first quarter of 2010. The segment continued to benefit from increased horizontal drilling and completion related activity and the associated escalation in service intensity within U.S. resource plays. All significant U.S. service lines contributed to the improved performance, with the largest contribution from pressure pumping and coiled tubing. Price improvement in some service lines and select geographic areas also positively impacted the results of the segment.

Drilling Services segment revenue was $40.4 million during the second quarter of 2010, versus $35.1 million reported for the prior quarter, representing an increase of 15%. The segment reported Adjusted EBITDA of $8.7 million, up 60% versus the first quarter of 2010. The improved performance of the segment is attributable to improved pricing and utilization for contract drilling and rig relocation services.

In comparison to the second quarter of 2009, consolidated revenue increased $121.8 million, or 51%, operating income increased $62.8 million, Adjusted EBITDA increased $56.8 million and net income increased by $41.5 million, or $0.54 per diluted share.

“We delivered outstanding performance during the second quarter,” commented Joe Winkler, Chairman and CEO. “U.S. activity levels continued to improve throughout the quarter, particularly in oil and liquid-rich resource plays, and we are executing well in the field.”

“We believe our reputation, market position and balance sheet will allow us to capitalize on attractive growth opportunities. Beginning in the third quarter of 2010, we will start deploying additional pressure pumping capacity, most of which will be committed under long-term contracts. The deployment will include two frac fleets in the Eagle Ford Shale of South Texas, a frac fleet in the Marcellus Shale and additional pressure pumping capacity in the Bakken Shale. As a result of our investments, we anticipate our 2010 capital expenditures will be between $155 and $165 million.”

“We remain pleased with how the company is positioned, believe activity in oil and liquid-rich plays will remain robust for the foreseeable future and are optimistic regarding the near-term and long-term outlook for the North American natural gas markets,” 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.
