Patterson-UTI Energy Reports Financial Results for Three and Twelve Months Ended December 31,
2011
Annual Revenues Up by 75%, Net Income by 176%

HOUSTON, Texas – February 2, 2012 – PATTERSON-UTI ENERGY, INC. (NASDAQ: PTEN)today reported financial results for the three and twelve months ended December 31, 2011. The Company reported net income of $87.6 million, or $0.56 per share, for the fourth quarter of 2011, compared to net income of $53.9 million, or $0.35 per share, for the quarter ended December 31, 2010. Revenues for the fourth quarter of 2011 were $725 million, compared to $506 million for the fourth quarter of 2010.

The Company reported net income of $322 million, or $2.06 per share, for the twelve months ended December 31, 2011, compared to net income of $117 million, or $0.76 per share, for the twelve months ended December 31, 2010. Revenues for the twelve months ended December 31, 2011 were $2.6 billion, compared to $1.5 billion for 2010.

The financial results for the three months ended December 31, 2011 include pretax impairment charges of $11.3 million ($7.1 million after-tax) from the retirement of thirty-one of the Company’s rigs. The financial results for the twelve months ended December 31, 2011 include pretax impairment charges of $15.7 million ($10.0 million after-tax), from the retirement of fifty-three of the Company’s rigs. Components from these rigs are available as spare parts to support other rigs in the fleet. These retirements reduced net income per share for the three and twelve months ended December 31, 2011 by $0.05 and $0.06, respectively.

Douglas J. Wall, Patterson-UTI’s Chief Executive Officer, stated, “Activity in our drilling business continued to increase in the fourth quarter, as our average number of rigs operating increased to 232, including 220 in the United States and 12 in Canada. This compares to an average of 221 rigs operating in the third quarter of 2011, including 209 in the United States and 12 in Canada.”

Mr. Wall added, “Average revenue per operating day for the fourth quarter of 2011 increased by $540 to $21,980, compared to $21,440 for the third quarter of 2011. Average direct operating costs per operating day for the fourth quarter of 2011 decreased to $12,700 from $12,980 for the third quarter of 2011, primarily as a result of repairs and maintenance costs decreasing from the unusually high level experienced in the third quarter. Average margin per operating day for the fourth quarter of 2011 increased by $820 to $9,280, compared to $8,460 for the third quarter of 2011.

“Demand for our rigs continues to be strong and our rig count has continued to increase. We expect to average approximately 241 rigs operating in January, comprised of 225 in the United States and 16 in Canada.

“We have continued to increase our contract coverage and currently have long-term contracts providing for approximately $1.8 billion of dayrate drilling revenue for 2012 and beyond. Based on contracts currently in place, we expect to have an average of approximately 120 rigs operating under long-term contracts during 2012, including an average of approximately 131 rigs in the first quarter.

“We completed 7 new Apex™ rigs during the fourth quarter, bringing our 2011 total to 25 new rigs. We expect to complete an additional 30 new Apex™ rigs in 2012, of which 13 are currently under long-term contract.

“In the fourth quarter, our pressure pumping business achieved sequential increases in revenue and operating income of 7% and 2%, respectively. Fourth quarter revenue growth was disappointing, as a result of certain customer specific delays, and less demand for short notice work late in the quarter. The soft demand during late fourth quarter in our northeast pressure pumping business has continued in the first quarter, but we are expecting all crews to be active by the end of the quarter.

“We took delivery of approximately 200,000 horsepower of new fracturing equipment during 2011, including 58,750 horsepower that was delivered at the end of the year. The northeast portion of the horsepower delivered at the end of the year is expected to start work late in the first quarter. Our pressure pumping fleet ended the year at approximately 631,000 horsepower. We expect to take delivery of an additional 140,000 horsepower in 2012,” he concluded.

Mark S. Siegel, Chairman of Patterson-UTI, stated, “Highlights of 2011 included: a 75% increase in revenue, an 80% increase in EBITDA and 176% increase in net income. We also completed construction of 25 new Apex™ rigs and took delivery of approximately 200,000 horsepower of pressure pumping equipment. The continued highgrading of our rig fleet and growth in our pressure pumping business, combined with appreciable investments in people, safety and training, have had a transformational effect on the Company over the past few years.

“As we look forward, we know that our investors and customers are concerned about the effects on our industry of current unusually low gas prices. As we now see it, increased activity in oil and liquids rich areas, driven by high oil prices, is likely to offset most if not all of the rigs and pressure pumping equipment that may become available as a result of lower natural gas related activity.

“Our exposure to low natural gas prices is mitigated by our long-term contract coverage. We currently have less than 30 rigs drilling for dry gas under contracts that are well-to-well or that have an initial term of less than one year. Moreover, in pressure pumping, the majority of our fracturing horsepower is located in oil and liquids rich areas. In addition, approximately 30% of our fracturing horsepower is under take-or-pay term contracts.

“Given the strength and flexibility of our balance sheet, term contract coverage, together with our experience in dealing with industry changes, we are well positioned for 2012,” he concluded.

The Company declared a quarterly cash dividend on its common stock of $0.05 per share, to be paid on March 30, 2012 to holders of record as of March 15, 2012.
