PATTERSON-UTI ENERGY, INC. AND SUBSIDIARIES
NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
1. Basis of Consolidation and Presentation
     The interim unaudited consolidated financial statements include the accounts of Patterson-UTI Energy, Inc. (the “Company”) and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. The Company has no controlling financial interests in any entity that is not a wholly-owned subsidiary and which would require consolidation.
     The interim consolidated financial statements have been prepared by management of the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been omitted pursuant to such rules and regulations, although the Company believes the disclosures included either on the face of the financial statements or herein are sufficient to make the information presented not misleading. In the opinion of management, all adjustments which are of a normal recurring nature considered necessary for a fair presentation of the information in conformity with accounting principles generally accepted in the United States have been included. The Unaudited Consolidated Balance Sheet as of December 31, 2007, as presented herein, was derived from the audited balance sheet of the Company, but does not include all disclosures required by accounting principles generally accepted in the United States of America. These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2007.
     The U.S. dollar is the functional currency for all of the Company’s operations except for its Canadian operations, which use the Canadian dollar as their functional currency. The effects of exchange rate changes are reflected in accumulated other comprehensive income, which is a separate component of stockholders’ equity.
     The Company provides a dual presentation of its net income per common share in its Unaudited Consolidated Statements of Income: Basic net income per common share (“Basic EPS”) and diluted net income per common share (“Diluted EPS”). Basic EPS excludes dilution and is computed by dividing net income by the weighted average number of common shares outstanding during the period excluding nonvested restricted stock. Diluted EPS is based on the weighted-average number of common shares outstanding plus the impact of dilutive instruments, including stock options and restricted stock using the treasury stock method. The following table presents information necessary to calculate net income per share for the three months ended March 31, 2008 and 2007 as well as potentially dilutive securities excluded from the weighted average number of diluted common shares outstanding, as their inclusion would have been anti-dilutive during the three months ended March 31, 2008 and 2007 (in thousands, except per share amounts):

     Reclassifications — Certain reclassifications have been made to the 2007 consolidated financial statements in order for them to conform with the 2008 presentation.
     The results of operations for the three months ended March 31, 2008 are not necessarily indicative of the results to be expected for the full year.
2. Stock-based Compensation
     The Company recognizes the cost of share-based awards under the fair-value-based method. The Company uses share-based awards to compensate employees and non-employee directors. All awards have been equity instruments in the form of stock

options or restricted stock awards and have included both service and, in certain cases, performance conditions. The Company issues shares of common stock when vested stock option awards are exercised and when restricted stock awards are granted.
     Stock Options. The Company estimates the grant date fair values of stock options using the Black-Scholes-Merton valuation model (“Black-Scholes”). Volatility assumptions are based on the historic volatility of the Company’s common stock over the most recent period equal to the expected term of the options as of the date the options are granted. The expected term assumptions are based on the Company’s experience with respect to employee stock option activity. Dividend yield assumptions are based on the expected dividends at the time the options are granted. The risk-free interest rate assumptions are determined by reference to United States Treasury yields. Weighted-average assumptions used to estimate the grant date fair values for stock options granted in the three-month periods ended March 31, 2008 and 2007 follow:
                 
    Three Months Ended  
    March 31,

     Restricted Stock. Under all restricted stock awards to date, shares were issued when granted, nonvested shares are subject to forfeiture for failure to fulfill service conditions and, in certain cases, performance conditions. Nonforfeitable dividends are paid on nonvested restricted shares.
     Restricted stock activity from January 1, 2008 to March 31, 2008 follows:

5. Business Segments
     The Company’s revenues, operating profits and identifiable assets are primarily attributable to four business segments: (i) contract drilling of oil and natural gas wells, (ii) pressure pumping services, (iii) drilling and completion fluid services and (iv) the investment, on a working interest basis, in production of oil and natural gas. Each of these segments represents a distinct type of business based upon the type and nature of services and products offered. These segments have separate management teams which report to the Company’s chief operating decision maker and have distinct and identifiable revenues and expenses. Separate financial data for each of our four business segments is provided below (in thousands):

9. Borrowings Under Line of Credit
     The Company has an unsecured revolving line of credit (“LOC”) with a maximum borrowing capacity of $375 million. Interest is paid on outstanding LOC balances at a floating rate ranging from LIBOR plus 0.625% to 1.0% or the prime rate at the Company’s election. Any outstanding borrowings must be repaid at maturity on December 16, 2009. This arrangement includes various fees, including a commitment fee on the average daily unused amount (0.15% at March 31, 2008). There are customary restrictions and covenants associated with the LOC. Financial covenants provide for a maximum debt to capitalization ratio and a minimum interest coverage ratio. The Company does not expect that the restrictions and covenants will impact its ability to operate or react to opportunities that might arise. As of March 31, 2008, the Company had no borrowings outstanding under the LOC and $58.6 million in letters of credit outstanding. As a result, the Company had available borrowing capacity of approximately $316 million at March 31, 2008.
10. Commitments, Contingencies and Other Matters
     Commitments — As of March 31, 2008, the Company maintained letters of credit in the aggregate amount of $58.6 million for the benefit of various insurance companies as collateral for retrospective premiums and retained losses which could become payable under the terms of the underlying insurance contracts. These letters of credit expire at various times during the calendar year and are typically renewed annually. As of March 31, 2008, no amounts had been drawn under the letters of credit.
     As of March 31, 2008, the Company had non-cancelable commitments to purchase approximately $80.3 million of equipment.
     The Company is party to various legal proceedings arising in the normal course of its business. The Company does not believe that the outcome of these proceedings, either individually or in the aggregate, will have a material adverse effect on its financial condition, results of operations or cash flows.
11. Stockholders’ Equity
     Cash Dividends — The Company has paid cash dividends during the three months ended March 31, 2008 and 2007 as follows:

     On April 30, 2008, the Company’s Board of Directors approved a cash dividend on its common stock in the amount of $0.16 per share to be paid on June 27, 2008 to holders of record as of June 12, 2008. The amount and timing of all future dividend payments, if any, is subject to the discretion of the Board of Directors and will depend upon business conditions, results of operations, financial condition, terms of the Company’s credit facilities and other factors.
     On August 1, 2007, the Company’s Board of Directors approved a stock buyback program (“Program”), authorizing purchases of up to $250 million of the Company’s common stock in open market or privately negotiated transactions. No purchases were made under the Program during the three months ended March 31, 2008. As of March 31, 2008, the Company has authority remaining under the Program to purchase approximately $180 million of the Company’s outstanding common stock. Shares purchased under the Program are accounted for as treasury stock.
     The Company purchased 17,861 shares of treasury stock from employees during the three months ended March 31, 2008. These shares were purchased at fair market value upon the vesting of restricted stock to provide the employees with the funds necessary to satisfy their respective tax withholding obligations. The total purchase price for these shares was approximately $347,000.

12. Income Taxes
     The Company adopted Financial Accounting Standards Board (“FASB”) Interpretation No. 48, Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement No. 109 (“FIN 48”) on January 1, 2007. FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. As of March 31, 2008, the Company had no unrecognized tax benefits. In connection with the adoption of FIN 48, the Company established a policy to account for interest and penalties with respect to income taxes as operating expenses. As of March 31, 2008, the tax years ended December 31, 2004 through December 31, 2006 are open for examination by U.S. taxing authorities. As of March 31, 2008, the tax years ended December 31, 2003 through December 31, 2006 are open for examination by Canadian taxing authorities.
13. Recently Issued Accounting Standards
     In September 2006, the FASB issued Statement No. 157, Fair Value Measurements (“FAS 157”). FAS 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurement. The initial application of FAS 157 is limited to financial assets and liabilities and became effective on January 1, 2008 for the Company. The impact of the initial application was not material. The Company will adopt FAS 157 on a prospective basis for nonfinancial assets and liabilities that are not measured at fair value on a recurring basis on January 1, 2009. The application of FAS 157 to the Company’s nonfinancial assets and liabilities will primarily be limited to assets acquired and liabilities assumed in a business combination, asset retirement obligations and asset impairments, including goodwill and long-lived assets, and this application is not expected to have a material impact to the Company.

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
     Management Overview — We are a leading provider of contract services to the North American oil and natural gas industry. Our services primarily involve the drilling, on a contract basis, of land-based oil and natural gas wells and, to a lesser extent, we provide pressure pumping services and drilling and completion fluid services. In addition to the aforementioned contract services, we also invest, on a working interest basis, in production of oil and natural gas. For the three months ended March 31, 2008 and 2007, our operating revenues consisted of the following (dollars in thousands):
                                 
    Three Months Ended March 31,  
    2008     2007  
Contract drilling
  $ 420,149       84 %   $ 467,498       85 %
Pressure pumping
    42,864       8       38,584       7  
Drilling and completion fluids
    32,550       6       30,760       6  
Oil and natural gas
    8,991       2       10,259       2  
 
                       
 
  $ 504,554       100 %   $ 547,101       100 %
 
                       
     We provide our contract services to oil and natural gas operators in many of the oil and natural gas producing regions of North America. Our contract drilling operations are focused in various regions of Texas, New Mexico, Oklahoma, Arkansas, Louisiana, Mississippi, Alabama, Colorado, Utah, Wyoming, Montana, North Dakota, South Dakota, Pennsylvania and Western Canada, while our pressure pumping services are focused primarily in the Appalachian Basin. Our drilling and completion fluids services are provided to operators offshore in the Gulf of Mexico and on land in Texas, Southeastern New Mexico, Oklahoma and the Gulf Coast region of Louisiana. The oil and natural gas properties in which we hold working interests are primarily located in West and South Texas, Southeastern New Mexico, Utah and Mississippi.
     Typically, the profitability of our business is most readily assessed by two primary indicators in our contract drilling segment: our average number of rigs operating and our average revenue per operating day. During the first quarter of 2008, our average number of rigs operating was 244 per day compared to 241 in the fourth quarter of 2007 and 255 in the first quarter of 2007. Our average revenue per operating day decreased to $18,900 in the first quarter of 2008 from $19,250 in the fourth quarter of 2007 and $20,350 in the first quarter of 2007. Our consolidated net income for the first quarter of 2008 decreased by $38.4 million or 33% as compared to the first quarter of 2007. This decrease was primarily due to our contract drilling segment experiencing a decrease in the average number of rigs operating, a decrease in the average revenue per operating day and an increase in the average costs per operating day in the first quarter of 2008 as compared to the first quarter of 2007.
     Our revenues, profitability and cash flows are highly dependent upon prevailing prices for natural gas and, to a lesser extent, oil. During periods of improved commodity prices, the capital spending budgets of oil and natural gas operators tend to expand, which results in increased demand for our contract services. Conversely, in periods when these commodity prices deteriorate, the demand for our contract services generally weakens and we experience downward pressure on pricing for our services. In addition, our operations are highly impacted by competition, the availability of excess equipment, labor issues and various other factors which are more fully described as “Risk Factors” included as Item 1A in our Annual Report on Form 10-K for the fiscal year ended December 31, 2007.
     We believe that the liquidity shown on our balance sheet as of March 31, 2008, which includes approximately $257 million in working capital (including $50.3 million in cash and cash equivalents) and approximately $316 million available under a $375 million line of credit, provides us with the ability to pursue acquisition opportunities, expand into new regions, make improvements to our assets, pay cash dividends and survive downturns in our industry.
     Commitments and Contingencies — As of March 31, 2008, we maintained letters of credit in the aggregate amount of $58.6 million for the benefit of various insurance companies as collateral for retrospective premiums and retained losses which could become payable under the terms of the underlying insurance contracts. These letters of credit expire at various times during each calendar year and are typically renewed annually. As of March 31, 2008, no amounts had been drawn under the letters of credit.
     As of March 31, 2008, we had non-cancelable commitments to purchase approximately $80.3 million of equipment.
     Trading and Investing — We have not engaged in trading activities that include high-risk securities, such as derivatives and non-exchange traded contracts. We invest cash primarily in highly liquid, short-term investments such as overnight deposits and money market accounts.
     Description of Business — We conduct our contract drilling operations in Texas, New Mexico, Oklahoma, Arkansas, Louisiana, Mississippi, Alabama, Colorado, Utah, Wyoming, Montana, North Dakota, South Dakota, Pennsylvania and Western Canada. As of

Table of Contents

March 31, 2008, we had approximately 350 currently marketable land-based drilling rigs. We provide pressure pumping services to oil and natural gas operators primarily in the Appalachian Basin. These services consist primarily of well stimulation and cementing for completion of new wells and remedial work on existing wells. We provide drilling fluids, completion fluids and related services to oil and natural gas operators offshore in the Gulf of Mexico and on land in Texas, Southeastern New Mexico, Oklahoma and the Gulf Coast region of Louisiana. Drilling and completion fluids are used by oil and natural gas operators during the drilling process to control pressure when drilling oil and natural gas wells. We also invest, on a working interest basis, in production of oil and natural gas.
     The North American land drilling industry has experienced periods of downturn in demand over the last decade. During these periods, there have been substantially more drilling rigs available than necessary to meet demand. As a result, drilling contractors have had difficulty sustaining profit margins during the downturn periods.
     In addition to adverse effects that future declines in demand could have on us, ongoing factors which could continue to adversely affect utilization rates and pricing, even in an environment of high oil and natural gas prices and increased drilling activity, include:
    movement of drilling rigs from region to region,
 
    reactivation of land-based drilling rigs, or
 
    construction of new drilling rigs.
     As a result of an increase in drilling activity and increased prices for drilling services in 2005 and 2006, construction of new drilling rigs increased significantly in that time period. The addition of new drilling rigs to the market resulted in excess capacity compared to demand, and construction of new drilling rigs moderated in 2007. We cannot predict either the future level of demand for our contract drilling services or future conditions in the oil and natural gas contract drilling business.
Critical Accounting Policies
     In addition to established accounting policies, our consolidated financial statements are impacted by certain estimates and assumptions made by management. No changes in our critical accounting policies have occurred since the filing of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2007.
Liquidity and Capital Resources
     As of March 31, 2008, we had working capital of $257 million including cash and cash equivalents of $50.3 million. For the three months ended March 31, 2008, our sources of cash flow included:
    $182 million from operating activities,
 
    $1.3 million in proceeds from the disposal of property and equipment, and
 
    $3.3 million from the exercise of stock options and related tax benefits associated with stock-based compensation.
     During the three months ended March 31, 2008, we used $18.5 million to pay dividends on our common stock, $50.0 million to repay borrowings under our line of credit and $84.6 million:
    to make capital expenditures for the betterment and refurbishment of our drilling rigs,
 
    to acquire and procure drilling equipment and facilities to support our drilling operations,
 
    to fund capital expenditures for our pressure pumping and drilling and completion fluids divisions, and
 
    to fund leasehold acquisition and exploration and development of oil and natural gas properties on a working interest basis.
     As of March 31, 2008, we had no borrowings outstanding under our $375 million revolving line of credit and had $58.6 million in letters of credit outstanding such that we had available borrowing capacity of approximately $316 million at March 31, 2008.

     On April 30, 2008, our Board of Directors approved a cash dividend on our common stock in the amount of $0.16 per share to be paid on June 27, 2008 to holders of record as of June 12, 2008. The amount and timing of all future dividend payments, if any, is subject to the discretion of the Board of Directors and will depend upon business conditions, results of operations, financial condition, terms of our credit facilities and other factors.
     On August 1, 2007, our Board of Directors approved a stock buyback program (“Program”), authorizing purchases of up to $250 million of our common stock in open market or privately negotiated transactions. No purchases were made under the Program during the three months ended March 31, 2008. As of March 31, 2008, we have authority remaining under the Program to purchase approximately $180 million of our outstanding common stock. Shares purchased under the Program are accounted for as treasury stock.
     We believe that the current level of cash and short-term investments, together with cash generated from operations, should be sufficient to meet our capital needs. From time to time, acquisition opportunities are evaluated. The timing, size or success of any acquisition and the associated capital commitments are unpredictable. Should opportunities for growth requiring capital arise, we believe we would be able to satisfy these needs through a combination of working capital, cash generated from operations, our existing credit facility and additional debt or equity financing. However, there can be no assurance that such capital would be available on reasonable terms, if at all.
Results of Operations
     The following tables summarize operations by business segment for the three months ended March 31, 2008 and 2007:

Average rigs operating
    244       255       (4.3 )%
Capital expenditures
  $ 67,211     $ 153,276       (56.2 )%
     The reactivation and construction of new land drilling rigs in the United States has resulted in excess capacity compared to recent demand. As a result, our average rigs operating have declined to 244 in the first quarter of 2008 compared to 255 in the first quarter of 2007.
     Revenues in the first quarter of 2008 decreased as compared to the first quarter of 2007 as a result of decreases in the number of operating days and in the average revenue per operating day. Direct operating costs in the first quarter of 2008 decreased as compared to the first quarter of 2007 as a result of the decreased number of operating days. Operating days, average rigs operating and average revenue per operating day decreased in the first quarter of 2008 as a result of decreased demand for our contract drilling services resulting from the excess capacity discussed above. Significant capital expenditures have been incurred to activate additional drilling rigs, to modify and upgrade our drilling rigs and to acquire additional related equipment such as drill pipe, drill collars, engines, fluid circulating systems, rig hoisting systems and safety enhancement equipment. The increase in depreciation expense was a result of the capital expenditures discussed above.

     Revenues and direct operating costs increased as a result of the increased number of jobs, as well as an increase in the average revenue and average direct operating costs per job. The increase in jobs was attributable to increased demand for our services and increased operating capacity. However, our pressure pumping operations were negatively impacted by wet locations that resulted from a lack of consistently cold weather in the Appalachian Basin during the first quarter of 2008 causing jobs that had been scheduled during the quarter to be postponed. Increased average revenue per job was due to increased pricing for our services and an increase in the number of larger jobs being driven by demand for services associated with unconventional reservoirs in the Appalachian Basin. Average direct operating costs per job increased as a result of increases in compensation, maintenance and the cost of materials used in our operations, as well as an increase in the number of larger jobs. Additionally, the postponement of scheduled jobs during the quarter as discussed above contributed to the increase in average direct operating costs per job. Selling, general and administrative expense increased primarily as a result of expenses to support the expanding operations of the pressure pumping segment. Significant capital expenditures have been incurred to add capacity, expand our areas of operation and modify and upgrade existing equipment. The increase in depreciation expense is a result of the capital expenditures discussed above.

     Revenues decreased due to a decrease in the average net daily production of oil and natural gas, partially offset by increases in the average sales price of oil and natural gas. Revenues also declined due to the sale in the fourth quarter of 2007 of the operating responsibilities associated with oil and natural gas wells and the loss of the related well operations revenue. Average net daily oil and natural gas production decreased primarily due to the sale of certain properties in the second quarter of 2007 and production declines in certain wells. The decrease in direct operating costs is primarily due to a decrease of approximately $797,000 in costs associated with the abandonment of exploratory wells. Selling, general and administrative expenses decreased in the first quarter of 2008 due to the sale of operating responsibilities mentioned above and the resulting elimination of headcount in our oil and natural gas production and exploration segment. Depreciation, depletion and impairment expense in the first quarter of 2008 includes approximately $221,000 incurred to impair certain oil and natural gas properties compared to approximately $530,000 incurred to impair certain oil and natural gas properties in

Recently Issued Accounting Standards
     In September 2006, the FASB issued Statement No. 157, Fair Value Measurements (“FAS 157”). FAS 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurement. The initial application of FAS 157 is limited to financial assets and liabilities and became effective on January 1, 2008 for us. The impact of the initial application was not material. We will adopt FAS 157 on a prospective basis for nonfinancial assets and liabilities that are not measured at fair value on a recurring basis on January 1, 2009. The application of FAS 157 to our nonfinancial assets and liabilities will primarily be limited to assets acquired and liabilities assumed in a business combination, asset retirement obligations and asset impairments, including goodwill and long-lived assets, and this application is not expected to have a material impact to us.
Volatility of Oil and Natural Gas Prices and its Impact on Operations
     Our revenue, profitability, and rate of growth are substantially dependent upon prevailing prices for natural gas and, to a lesser extent, oil. For many years, oil and natural gas prices and markets have been volatile. Prices are affected by market supply and demand factors as well as international military, political and economic conditions, and the ability of OPEC to set and maintain production and price targets. All of these factors are beyond our control. During 2006, the average market price of natural gas retreated from record highs that were set in 2005. The price dropped from an average of $8.98 per Mcf in 2005 to an average of $6.94 per Mcf in 2006 and an average of $7.18 per Mcf in 2007. This resulted in our customers moderating their increase in drilling activities during 2007. This moderation combined with the reactivation and construction of new land drilling rigs in the United States has resulted in excess capacity compared to recent demand. Additionally, drilling activity in Canada has slowed significantly. As a result of these factors, our average rigs operating declined to 244 for the three months ended March 31, 2008 compared to 255 for the comparable period in 2007. We expect oil and natural gas prices to continue to be volatile and to affect our financial condition, operations and ability to access sources of capital. A significant decrease in market prices for natural gas could result in a material decrease in demand for drilling rigs and adversely affect our operating results.
     The North American land drilling industry has experienced many downturns in demand over the last decade. During these periods, there have been substantially more drilling rigs available than necessary to meet demand. As a result, drilling contractors have had difficulty sustaining profit margins during the downturn periods.

Impact of Inflation
     Inflation has not had a significant impact on our operations during the three months ended March 31, 2008. We believe that inflation will not have a significant near-term impact on our financial position.
ITEM 3. Quantitative and Qualitative Disclosures About Market Risk
     We currently have exposure to interest rate market risk associated with borrowings under our credit facility. The revolving credit facility calls for periodic interest payments at a floating rate ranging from LIBOR plus 0.625% to 1.0% or at the prime rate at our election. The applicable rate above LIBOR is based upon our debt to capitalization ratio. Our exposure to interest rate risk due to changes in the prime rate or LIBOR is not material due to the fact that we had no outstanding borrowings as of March 31, 2008.
     We conduct some business in Canadian dollars through our Canadian land-based drilling operations. The exchange rate between Canadian dollars and U.S. dollars has fluctuated during the last several years. If the value of the Canadian dollar against the U.S. dollar weakens, revenues and earnings of our Canadian operations will be reduced and the value of our Canadian net assets will decline when they are translated to U.S. dollars. This currency rate risk is not material to our results of operations or financial condition.
ITEM 4. Controls and Procedures
     Disclosure Controls and Procedures — We maintain disclosure controls and procedures (as such terms are defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), designed to ensure that the information required to be disclosed in the reports that we file with the SEC under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), as appropriate, to allow timely decisions regarding required disclosure.
     Under the supervision and with the participation of our management, including our CEO and CFO, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on that evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective as of March 31, 2008.
     Changes in Internal Control Over Financial Reporting —There were no changes in our internal control over financial reporting during our most recently completed fiscal quarter that have materially affected or are reasonably likely to materially affect our internal control over financial reporting, as defined in Rule 13a-15(f) under the Exchange Act.
