Exhibit 99.2

UNAUDITED PRO FORMA CONDENSED

CONSOLIDATED FINANCIAL INFORMATION

On April 22, 2013, Parker Drilling Company (“Parker Drilling”) and two of its wholly-owned subsidiaries, Parker Drilling Offshore Corporation (“Parker Offshore”) and PD International Holdings C.V. (“PD International” and, together with Parker Drilling and Parker Offshore, the “Parker Parties”), entered into a Sale and Purchase Agreement (the “Agreement”) with ITS Tubular Services (Holdings) Limited (“ITS Holdings”), a company organized under the laws of Scotland and in administration proceedings under the laws thereof (the “Seller”), Ian David Green, John Bruce Cartwright and Graham Douglas Frost, each of PricewaterhouseCoopers LLP, as joint administrators of the Seller, and ITS Holdings, Inc., an indirect subsidiary of the Seller. Pursuant to the Agreement, Parker Drilling acquired International Tubular Services Limited and certain of its affiliates (collectively, “ITS”) and other related assets held by the Seller (the “Acquisition”) for an initial purchase price of $101.0 million paid at the closing of the Acquisition. An additional $24.0 million was deposited into an escrow account, which will either be paid to the Seller as additional purchase price when certain consents are obtained or, in certain circumstances, released to either the Seller or the Parker Parties, as the case may be, in accordance with the Agreement. The Acquisition closed simultaneously with the execution of the Agreement. The following unaudited pro forma condensed consolidated financial information and related notes give effect to the Acquisition and related transactions and financing and should be read in conjunction with the quarterly condensed and historical annual consolidated financial information of Parker Drilling filed with the Securities and Exchange Commission on Form 10-Q for the Quarterly Period Ended March 31, 2013 and Form 10-K for the Year Ended December 31, 2012, as well as the historical annual financial information of ITS Holdings filed as Exhibit 99.1 to this Current Report, including the respective notes thereto. The unaudited pro forma condensed consolidated financial information gives effect to the Acquisition in accordance with the acquisition method of accounting. We believe all significant adjustments necessary to reflect the effects of the Acquisition and related transactions and financing have been made.

NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION

1. Basis of Presentation

The accompanying unaudited pro forma condensed consolidated financial information presents the pro forma results of operations of Parker Drilling and ITS on a consolidated basis based on the historical financial information of each company after giving effect of the Acquisition and related transactions and financing. The unaudited pro forma condensed consolidated financial information was prepared in accordance with Securities and Exchange Commission Regulation S-X Article 11, using the acquisition method of accounting, and are based on the historical financial statements of Parker Drilling and ITS Holdings after giving effect to the consideration paid by Parker Drilling to consummate the Acquisition and related transactions and financing, as well as pro forma adjustments.

Financial Accounting Standards Board (“FASB”)’s Accounting Standards Codification (“ASC”) 805, Business Combinations (“ASC 805”), requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values, as determined in accordance with ASC 820, Fair Value Measurements, as of the acquisition date. In addition, the applicable accounting literature requires that consideration transferred be measured at the closing date of the asset acquisition, which may be different than the amount of consideration assumed in these unaudited pro forma condensed consolidated financial information.

Under the acquisition method of accounting, the assets acquired and liabilities assumed will be recorded as of the completion of the acquisition, primarily at their respective fair values and added to those of Parker Drilling. The results of operations of ITS will be reflected in the financial statements and reported results of operations of Parker Drilling from the date of acquisition but Parker Drilling’s financial statements will not be retroactively restated to reflect the historical financial position or results of operations of ITS.

The unaudited pro forma condensed consolidated balance sheet is presented “as if” the Acquisition had occurred on March 31, 2013. The unaudited pro forma condensed consolidated statements of operations for the year ended December 31, 2012 and the three months ended March 31, 2013 are presented “as if” the Acquisition had occurred on January 1, 2012, representing the beginning of the earliest period presented.

Acquisition-related transaction costs (i.e., advisory, legal, valuation, and other professional fees) and certain acquisition-related restructuring charges impacting ITS are expensed in the period in which the costs are incurred. Total advisory, legal, regulatory, and valuation costs incurred by Parker Drilling in connection with the Acquisition are estimated to total approximately $13.0 million.

2. Accounting Policies and Presentation

The unaudited pro forma financial information has been compiled in a manner consistent with the accounting policies adopted by Parker Drilling. Certain reclassifications and adjustments have been made to ITS Holdings’ historical financial information presented herein to conform to Parker Drilling’s historical presentation.

The following are reconciliations of amounts presented in ITS Holdings’ consolidated income statement for the year ended December 31, 2012 (in thousands):

3. Adjustments to ITS Holdings’ Financial Statements to Reconcile to U.S. GAAP

ITS Holdings’ financial statements were prepared in accordance with IFRS, as issued by IASB, which differ in certain respects from U.S. GAAP. Adjustments have been made with respect to the following items to reconcile ITS Holdings’ historical IFRS financial statements to U.S. GAAP for the purposes of the pro forma presentation. Significant adjustments include:

7

As of March 31, 2013, an adjustment of approximately $1.0 million was made to adjust beginning Accumulated deficit and Other noncurrent assets for the difference in the amortization methods of financing costs. In addition, an adjustment of approximately $0.3 million was made to reclassify the financing costs recorded as a debt discount under IFRS to Other noncurrent assets under U.S. GAAP. For the three months ended March 31, 2013, the adjustment reflected for the difference in the amortization methods resulted in an increase to Interest expense and a corresponding decrease to Other noncurrent assets of approximately $0.2 million. Therefore, the net impact to Other noncurrent assets to record the adjustments to deferred financing costs as of March 31, 2013 under U.S. GAAP is approximately $1.1 million. This additional interest expense is reflected as an adjustment in the unaudited pro forma condensed consolidated statement of operations as an IFRS to U.S. GAAP adjustment. For the year ended December 31, 2012, the adjustment to reduce interest expense of $0.6 million has been made for the difference in amortization methods. See also reconciliation of interest expense and accumulated deficit at 3(h) and 3(i) below.

Under U.S. GAAP, such shares are classified as temporary equity (mezzanine debt). An adjustment has been made as of March 31, 2013 to record temporary equity for the original issuing price of the shares of $56.9 million, net of financing costs, in accordance with U.S. GAAP and eliminate the $57.4 million and $7.8 million, respectively, in current liabilities and equity which were recorded under IFRS.

Beginning accumulated deficit was reduced by $8.2 million as of December 31, 2012 due to differences in the treatment of the preferential dividend and the initial recognition of the share issuances.

Interest expense for the year ended December 31, 2012 and the three months ended March 31, 2013, was decreased by $10.6 million and $1.5 million, respectively, as the fixed cumulative preferential dividend is treated as a dividend under U.S. GAAP.

See also notes 3(h) and 3(i) for reconciliation of accumulated deficit and interest expense.

4. Adjustments for ITS Entities and Operations Not Acquired

The Parker Parties did not acquire certain entities or geographic operations of ITS Holdings reflected in the historical financial information of ITS Holdings. These entities or operations were related to the operations in Iran, Sudan, Peru, Ecuador, Venezuela, Pakistan, Cyprus, Spain, and Brazil, and certain non-core operations in the U.S. that were sold as part of another transaction prior to the Acquisition. The UK holding company that held ITS Holdings’ capital shares, debt and debt related accounts was also not acquired. Accordingly, adjustments have been made to remove the net assets and results of operations, as well as impairment and restructuring charges, attributable to these entities so as to reflect the assets acquired and liabilities assumed by Parker Drilling.

5. Purchase Price Allocation

The total purchase price of the acquisition was $125.0 million. The purchase consideration was comprised of $101.0 million of cash paid at closing and $24.0 million of cash deposited in escrow. Of the $24.0 million deposited in escrow, $5.0 million is contingent consideration. The total purchase consideration of $125.0 million was allocated to the net tangible and intangible assets acquired and liabilities assumed based on their estimated fair values as if the Acquisition took place on March 31, 2013. The information below represents the preliminary purchase price allocation of ITS (in thousands):
