NOTE 1 — NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

Allis-Chalmers Energy Inc. and subsidiaries (“Allis-Chalmers”, “we”, “our” or “us”) is a multi-faceted oilfield service company that provides services and equipment to oil and natural gas exploration and production companies throughout the United States including Texas, Louisiana, Pennsylvania, Arkansas, West Virginia, Oklahoma, Colorado, offshore in the Gulf of Mexico, and internationally, primarily in Argentina, Brazil, Bolivia and Mexico. We operate in two sectors of the oil and natural gas service industry: Well Services and Drilling Services.

We derive operating revenues from rates per day and rates per job that we charge for the labor and equipment required to provide a service and rates per day for equipment and tools that we rent to our customers. The price we charge for our services depends upon several factors, including the level of oil and natural gas drilling activity and the competitive environment in the particular geographic regions in which we operate. Contracts are awarded based on price, quality of service and equipment and general reputation and experience of our personnel. The principal operating costs are direct and indirect labor and benefits, repairs and maintenance of our equipment, insurance, equipment rentals, fuel, depreciation and general and administrative expenses.

Basis of Presentation

On February 23, 2011, Allis-Chalmers Energy Inc., a Delaware corporation, completed its merger (the “Merger”) with and into Wellco Sub Company (“Wellco”), a Delaware corporation and wholly owned subsidiary of Seawell Limited (“Seawell”), with Wellco continuing as the surviving entity under the name Allis-Chalmers Energy Inc. The Merger was effected pursuant to the Agreement and Plan of Merger, dated as of August 10, 2010, by and among Allis-Chalmers, Seawell and Wellco, as amended by the Amendment Agreement, dated as of October 10, 2010, by and among Allis-Chalmers, Seawell and Wellco (as so amended, the “Merger Agreement”). Following the Merger, Seawell began operating under the name Archer Limited (“Archer” or “Parent”). As of the Merger date, our assets and liabilities have been adjusted to their fair values (see Note 2) based on the purchase price resulting in changes to depreciation, amortization and interest in the successor period; therefore, the financial information for the period subsequent to the Merger is not fully comparable. The financial statements and accompanying footnotes have been separated with a black line to present pre-merger activity as the “Predecessor” company and post-merger activity as the “Successor” company. “Predecessor” refers to the operations of Allis-Chalmers prior to the consummation of the Merger and “Successor” refers to the operations of Allis-Chalmers subsequent to the Merger. The Merger date for accounting purposes has been designated as March 1, 2011.

Our unaudited consolidated condensed financial statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission, or SEC. Accordingly, certain information and disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted. We believe that the presentations and disclosures herein are adequate to make the information not misleading. The unaudited consolidated condensed financial statements reflect all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of the interim periods. These unaudited consolidated condensed financial statements should be read in conjunction with our restated audited consolidated financial statements included in Amendment No. 1 to our Annual Report on Form 10-K for the year ended December 31, 2010 filed with the SEC on September 1, 2011 (the “Form 10-K/A”). The results of operations for the interim periods are not necessarily indicative of the results of operations to be expected for the full year.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Future events and their effects cannot be perceived with certainty. Accordingly, our accounting estimates require the exercise of judgment. While management believes that the estimates and assumptions used in the preparation of the consolidated financial statements are appropriate, actual results could differ from those estimates. Estimates are used for, but are not limited to, determining the following: allowance for doubtful accounts; recoverability of long-lived assets and intangibles; useful lives used in depreciation and amortization; stock-based compensation; income taxes and valuation allowances. The accounting estimates used in the preparation of the consolidated financial statements may change as new events occur, as more experience is acquired, as additional information is obtained or as our operating environment changes.

NOTE 1 — NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Financial Instruments

Financial instruments consist of cash and cash equivalents, restricted cash, accounts receivable and payable, and debt. The carrying value of cash and cash equivalents, restricted cash and accounts receivable and payable approximate fair value due to their short-term nature. Restricted cash relates to deposits at a financial institution to secure $3.8 million of outstanding letters of credit. We believe the fair values and the carrying value of our debt, excluding the senior notes, would not be materially different due to the instruments’ interest rates approximating market rates for similar borrowings at June 30, 2011. Our senior notes, in the approximate aggregate amount of $446.6 million, trade “over the counter” in limited amounts and on an infrequent basis. In connection with the Merger, the recorded fair value of our senior notes was increased by $19.3 million based on the traded value at Merger date. The price at which our senior notes trade is based on many factors such as the level of interest rates, the economic environment, the outlook for the oilfield services industry and the perceived credit risk.

Recent Accounting Pronouncements

We consider all newly issued but not yet adopted accounting pronouncements applicable to our operations and the preparation of our consolidated condensed financial statements. We do not believe that any issued accounting pronouncements not yet adopted by us will have a material impact on our consolidated condensed financial statements.

NOTE 2 — BUSINESS COMBINATIONS

Merger with Archer

Pursuant to the Merger, each outstanding share of common stock of Allis-Chalmers was converted into the right to receive either $4.25 cash or 1.15 fully paid and nonassessable Archer common shares. The fair value of total consideration was approximately $600.9 million with approximately 95% of Allis-Chalmers stockholders electing to receive 97.1 million Archer common shares in the Merger and the remainder receiving an aggregate of approximately $18 million in cash. The following table summarizes the preliminary allocation of the purchase price to the estimated fair value of the assets at Merger (in thousands):

Current assets		$	237,873
Property and equipment			682,406
Intangible assets, including goodwill			373,227
Other long-term assets			4,949
Total assets acquired			1,298,455
Current liabilities			148,360
Long-term liabilities			549,210
Merger net assets		$	600,885

Our historical property and equipment values were decreased by $47.1 million, our Senior Notes were increased by $19.3 million, other assets were decreased by $13.8 million and other long-term liabilities were increased by $8.6 million. The fair value assigned to the debt was based on actively traded prices and changes in other assets and liabilities were based on third-party valuations or other market based approaches. Goodwill of $267.4 million was recognized for this acquisition and was calculated as the excess of the consideration transferred over the fair value of the net assets acquired. It includes the expected synergies and other benefits that we believe will result from the combined operations and intangible assets that do not qualify for separate recognition such as assembled workforce. Other intangible assets included approximately $91.2 million assigned to customer lists, $6.7 million to trade name, $5.6 million to patents and $2.3 million to backlogs (see note 4). Goodwill is not tax deductible. The amortizable intangibles have a weighted-average useful life of 8.9 years. The allocation of the purchase price has been based upon preliminary fair values. Estimates and assumptions are subject to change upon management’s review of the final valuation.

NOTE 2 — BUSINESS COMBINATIONS (Continued)

Acquisition of AWC

On July 12, 2010, we acquired American Well Control, Inc., or AWC, for a total consideration of approximately $19.2 million, which included approximately $17.2 million in cash and 1.0 million shares of our common stock. AWC is a leading manufacturer of premium high-pressure valves used in hydraulic fracturing in the unconventional gas shale plays. The following table summarizes the allocation of the purchase price to the estimated fair value of the assets acquired at the date of acquisition (in thousands):

Current assets		$	7,585
Property and equipment			2,756
Intangible assets, including goodwill			11,749
Other long-term assets			2
Total assets acquired			22,092
Current liabilities			1,527
Long-term liabilities			1,401
Net assets acquired		$	19,164

AWC’s historical property and equipment values were increased by approximately $27,000 based on third-party valuations. Goodwill of $5.7 million was recognized for this acquisition and was calculated as the excess of the consideration transferred over the fair value of the net assets acquired. It includes the expected synergies and other benefits that we believe will result from the combined operations and intangible assets that do not qualify for separate recognition such as assembled workforce. Other intangible assets included approximately $5.6 million assigned to customer lists, $400,000 to trade name and $55,000 to non-competes. Goodwill is not tax deductible. The amortizable intangibles have a weighted-average useful life of 9.9 years.

NOTE 3 — STOCK-BASED COMPENSATION

Under the Merger Agreement, holders of our outstanding stock options, whether or not then exercisable or vested, elected to receive, at the effective time of the Merger, either cash or fully exercisable and vested stock options to purchase Archer common shares. In addition, all restrictions on time-lapse and performance-based restricted stock awards were deemed to have lapsed and each restricted share was deemed to be an unrestricted share of our common stock. Our Incentive Stock Plans were terminated in connection with the Merger. Our net loss for the two months ended February 28, 2011 includes approximately $6.1 million of compensation costs related to share-based payments with approximately $5.4 million of this amount relating to the acceleration of stock based compensation expense associated with the Merger.

We recognize all share-based payments to employees and directors in the financial statements based on their grant-date fair values. We utilize the Black-Scholes model to determine fair value, which incorporates assumptions to value stock-based awards. The dividend yield on our common stock is assumed to be zero as we have historically not paid dividends and have no current plans to do so in the future. The expected volatility is based on historical volatility of our common stock. The risk-free interest rate is the related United States Treasury yield curve for periods within the expected term of the option at the time of grant. We estimate forfeiture rates based on our historical experience.

The following summarizes the Black-Scholes model assumptions used for the options granted in the three and six months ended June 30, 2010 (no options were granted during the three and six months ended June 30, 2011):

		Three Months				Six Months

NOTE 4 — GOODWILL AND INTANGIBLE ASSETS

Goodwill and other intangible assets with infinite lives are not amortized, but tested for impairment annually or more frequently if circumstances indicate that impairment may exist. Intangible assets with finite useful lives are amortized either on a straight-line basis over the asset’s estimated useful life or on a basis that reflects the pattern in which the economic benefits of the intangible assets are realized. Goodwill was $267.4 million and $46.3 million at June 30, 2011 and December 31, 2010, respectively.

Definite-lived intangible assets that continue to be amortized relate to our purchase of customer-related and marketing-related intangibles patents and backlogs. These intangibles have useful lives ranging from four months to twenty years. Amortization of intangible assets for the three and four months ended June, 2011 and two months ended February 28, 2011 was $4.4 million, $5.8 million and $811,000, respectively, compared to $1.2 million and $2.3 million for the three and six months ended June 30, 2010, respectively. In connection with the Merger, a $5.1 million value was assigned to the Allis-Chalmers tradename. Following the Merger, Seawell and its subsidiaries, including us, have begun operating under the name Archer. As a result, it was determined that there was no material remaining value associated with the Allis-Chalmers tradename and the results for the four months ended June 30, 2011 includes an intangible asset impairment charge of $5.1 million. At June 30, 2011, intangible assets totaled $94.9 million, net of $5.8 million of accumulated amortization. Future amortization of intangible assets at June 30, 2011 is approximately $5.9 million for the remainder of 2011 and an average of approximately $11.6 million during the years ended 2012 through 2015.

NOTE 6- INCOME TAXES

In accordance with generally accepted accounting principles, we estimate the full-year effective tax rate from continuing operations and apply this rate to our year-to-date income from continuing operations. In addition, we separately calculate the tax impact of unusual items, if any. The consolidated effective tax rate for the two months ended February 28, 2011, three and four months ended June 30, 2011 was (9.9)%, 63.6% and 246.0%, respectively, compared to 23.4% and 25.8% for the three and six months ended June 30, 2010. The fluctuations in the tax rates are principally the result of valuation allowances on losses generated in the United States and variances in withholding taxes from foreign operations as a percentage of pretax income (loss).

Income (loss) before income taxes which was subject to United States and non-United States income taxes was as follow (in thousands):

Senior notes, bank loans and line of credit agreements

In January 2006 and August 2006, we closed on private offerings, to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, of $160.0 and $95.0 million aggregate principal amount of our senior notes, respectively. The senior notes are due January 15, 2014 and bear interest at 9.0%. The proceeds were used to fund the acquisitions of Specialty Rental Tools, Inc. and DLS, to repay existing debt and for general corporate purposes. In June 2009, we closed on a tender offer in which we purchased $30.6 million aggregate principal of our 9.0% senior notes for a total consideration of $650 per $1,000 principal amount. In connection with the Merger and based on actively traded prices of our senior notes, we increased the fair value of the 9.0% senior notes to $1,022 per $1,000 principal amount. In May 2011, pursuant to the terms of change of

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

NOTE 7 — DEBT (Continued)

control provisions in the indentures governing the senior notes and as a result of the Merger, holders had the right to require us to purchase, all or a portion of such holders’ Notes. We purchased $1.8 million aggregate principal of our 9.0% senior notes for a total consideration of $1,010 per $1,000 principal amount.

In January 2007, we closed on a private offering, to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, of $250.0 million principal amount of 8.5% senior notes due 2017. The proceeds of the senior notes offering, together with a portion of the proceeds of our concurrent common stock offering, were used to repay the debt outstanding under our $300.0 million bridge loan facility which we incurred to finance our acquisition of substantially all the assets of Oil & Gas Rental Services, Inc. On June 29, 2009, we closed on a tender offer in which we purchased $44.2 million aggregate principal of our 8.5% senior notes for a total consideration of $600 per $1,000 principal amount. In connection with the Merger and based on actively traded prices of our senior notes, we increased the fair value of the 8.5% senior notes to $1,070 per $1,000 principal amount. In May 2011, pursuant to the terms of change of control provisions in the indentures governing the senior notes and as a result of the Merger, we purchased $92,000 aggregate principal of our 8.5% senior notes for a total consideration of $1,010 per $1,000 principal amount.

We had a $90.0 million revolving line of credit with a final maturity date of April 26, 2012 pursuant to a revolving credit agreement that contained customary events of default and financial covenants and limited our ability to incur additional indebtedness, make capital expenditures, pay dividends or make other distributions, create liens and sell assets. Effective December 31, 2009, we amended the leverage and interest coverage ratio covenants of the revolving credit agreement. This amendment relaxed the required financial ratios for the quarter ended December 31, 2009 and for each of the quarters in 2010. Our obligations under the amended and restated credit agreement are secured by substantially all of our assets located in the United States. We were in compliance with all debt covenants as of December 31, 2010. As of December 31, 2010, we had $36.5 million of borrowings outstanding and $4.1 million in outstanding letters of credit under our revolving credit facility. The weighted-average interest rate was 7.8% at December 31, 2010. The revolving line of credit was repaid and terminated in connection with the Merger.

As part of our acquisition of DLS, we assumed various bank loans with floating interest rates based on LIBOR plus a margin and terms ranging from 2 to 5 years. The weighted average interest rate on these loans was 2.0% as of December 31, 2010. The outstanding amount due under these bank loans as of June 30, 2011 and December 31, 2010 was $0 and $350,000, respectively.

On February 15, 2008, through our DLS subsidiary in Argentina, we entered into a $25.0 million import finance facility with a bank. Borrowings under this facility were used to fund a portion of the purchase price of the new drilling and service rigs ordered for our Drilling Services segment. The loan is repayable over four years in equal semi-annual installments beginning one year after each disbursement with the final principal payment due not later than March 15, 2013. The import finance facility is unsecured and contains customary events of default and financial covenants and limits DLS’ ability to incur additional indebtedness, make capital expenditures, create liens and sell assets. We were in compliance with all debt covenants as of June 30, 2011 and December 31, 2010. The bank loan rates are based on LIBOR plus a margin. The weighted average interest rate was 4.2% at June 30, 2011 and December 31, 2010. The outstanding amount under the import finance facility as of June 30, 2011 and December 31, 2010 was $11.5 million and $14.4 million, respectively.

As part of our acquisition of BCH, we assumed a $23.6 million term loan credit facility with a bank. The credit agreement was dated June 2007 and contained customary events of default and financial covenants which were based on BCH’s stand-alone financial statements. The facility was repayable in quarterly principal installments plus interest and was to mature in August 2012. Obligations under the facility were secured by substantially all of the BCH assets. The bank waived certain financial ratio covenants for the December 31, 2010 measurement period and we classified the entire outstanding balance of the loan in the current portion of long-term debt. The interest rates were based on LIBOR plus a margin and the interest rate was 3.5% at December 31, 2010. The outstanding amount of the loan as of December 31, 2010 was $7.0 million. The term loan credit facility was paid in full in connection with the Merger.

On February 9, 2010, through our DLS subsidiary, we entered into a $4.0 million term loan facility. The loan is repayable in semi-annual installments beginning April 14, 2011 and bears interest at 8.5% per annum. The final maturity date is April 14, 2014 and the loan is unsecured. The outstanding amount under the term loan facility as of June 30, 2011 and December 31, 2010 was $3.4 million and $4.0 million, respectively

NOTE 7 — DEBT (Continued)

Notes payable

In 2010, we obtained insurance premium financings in the aggregate amount of $2.9 million with a fixed weighted-average interest rate of 4.8%. Under terms of the agreements, amounts outstanding are paid over eight and 11 month repayment schedules. The outstanding balance of these notes was approximately $0 and $1.0 million at June 30, 2011 and December 31, 2010, respectively.

NOTE 8 — STOCKHOLDERS’ EQUITY

During the two months ended February 28, 2011, we had option exercises and certain vesting in restricted stock grants which resulted in the issuance of 933,083 shares of our common stock. We retained 282,356 shares from employees in connection with the settlement of tax obligations arising from the vesting of restricted stock grants. We recognized approximately $6.1 million of compensation expense related to share-based payments during the two months ended February 28, 2011 that was recorded as capital in excess of par value (see Note 3).

Pursuant to the Merger, each share of our convertible preferred stock was converted to common stock and each outstanding share of common stock of Allis-Chalmers was converted into the right to receive either $4.25 cash or 1.15 fully paid and nonassessable Archer common shares. Holders of our outstanding stock options, whether or not then exercisable or vested, elected to receive, at the effective time of the merger, either cash or fully exercisable and vested stock options to purchase Archer common shares. In addition, all restrictions on time-lapse and performance-based restricted stock awards were deemed to have lapsed and each restricted share was deemed to be an unrestricted share of our common stock. Subsequent to the Merger, we have 1,000 shares authorized all of which have been issued to Archer Limited at a par value of $0.01 per share.
