NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1    Nature of Operations

Nabors is the largest land drilling contractor in the world and one of the largest land well-servicing and workover contractors in the United States and Canada:

• We actively market approximately 501 land drilling rigs for oil and gas land drilling operations in the U.S. Lower 48 states, Alaska, Canada, South and Central America, Mexico, the Middle East, the Far East, the South Pacific, Russia and Africa.

• We actively market approximately 567 rigs for land well-servicing and workover work in the United States and approximately 176 rigs for land well-servicing and workover work in Canada.

We are also a leading provider of offshore platform workover and drilling rigs, and actively market 40 platform, 12 jackup and four barge rigs in the United States, including the Gulf of Mexico, and multiple international markets.

In addition to the foregoing services:

• We provide hydraulic fracturing, cementing, nitrogen and acid pressure pumping services with over 765,000 hydraulic horsepower in key basins throughout the United States and Canada.

• We offer a wide range of ancillary well-site services, including engineering, transportation and disposal, construction, maintenance, well logging, directional drilling, rig instrumentation, data collection and other support services in select U.S. and international markets.

• We manufacture and lease or sell top drives for a broad range of drilling applications, directional drilling systems, rig instrumentation and data collection equipment, pipeline handling equipment and rig reporting software.

• We have a 51% ownership interest in a joint venture in Saudi Arabia, which owns and actively markets nine rigs in addition to the rigs we lease to the joint venture.

• We have invested in oil and gas exploration, development and production activities through both our wholly owned subsidiaries and our oil and gas joint ventures in which we hold 49-50% ownership interests.

The majority of our business is conducted through our Drilling and Other Rig Services and our Completion and Production business lines. Our Drilling and Other Rig Services business line includes our drilling of oil and natural gas wells, on land and offshore, and companies engaged in drilling technology, top drive manufacturing, directional drilling, construction services, and rig instrumentation and software. Our Completion and Production Services business line includes our well-servicing, fluid logistics, workover operations and our pressure pumping services. In addition to these two primary business lines, we have an Oil and Gas Operating segment. Our oil and gas exploration, development and production operations are included in our Oil and Gas Operating Segment, or in discontinued operations in some cases.

Unless the context requires otherwise, references in this report and in Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations to “we,” “us,” “our,” “Company” or “Nabors” mean Nabors Industries Ltd., together with our subsidiaries where the context requires, including Nabors Industries, Inc., a Delaware corporation (“Nabors Delaware”).

Note 2    Summary of Significant Accounting Policies

Interim Financial Information

The unaudited consolidated financial statements of Nabors are prepared in conformity with accounting principles generally accepted in the United States (“GAAP”). Certain reclassifications have been made to the prior

9

period to conform to the current-period presentation, with no effect on our consolidated financial position, results of operations or cash flows. Pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been omitted. Therefore, these financial statements should be read along with our annual report on Form 10-K for the year ended December 31, 2011 (“2011 Annual Report”). In management’s opinion, the consolidated financial statements contain all adjustments necessary to present fairly our financial position as of March 31, 2012 and the results of our operations, cash flows, changes in equity and other comprehensive income for the three months ended March 31, 2012 and 2011, in accordance with GAAP. Interim results for the three months ended March 31, 2012 may not be indicative of results that will be realized for the full year ending December 31, 2012.

Our independent registered public accounting firm has reviewed and issued a report on these consolidated interim financial statements in accordance with standards established by the Public Company Accounting Oversight Board. Pursuant to Rule 436(c) under the Securities Act of 1933, as amended (the “Securities Act”) this report should not be considered a part of any registration statement prepared or certified within the meanings of Sections 7 and 11 of such Act.

Principles of Consolidation

Our consolidated financial statements include the accounts of Nabors, as well as all majority-owned and nonmajority-owned subsidiaries required to be consolidated under GAAP. Our consolidated financial statements exclude majority-owned entities for which we do not have either (1) the ability to control the operating and financial decisions and policies of that entity or (2) a controlling financial interest in a variable interest entity. All significant intercompany accounts and transactions are eliminated in consolidation.

Investments in operating entities where we have the ability to exert significant influence, but where we do not control operating and financial policies, are accounted for using the equity method. Our share of the net income (loss) of these entities is recorded as earnings (losses) from unconsolidated affiliates in our consolidated statements of income (loss), and our investment in these entities is included as a single amount in our consolidated balance sheets. Investments in unconsolidated affiliates accounted for using the equity method totaled $303.1 million and $371.0 million as of March 31, 2012 and December 31, 2011, respectively. At each of March 31, 2012 and December 31, 2011, assets held for sale included investments in unconsolidated affiliates accounted for using the equity method totaling $13.7 million. See Note 3 — Discontinued Operations for additional information.

We have investments in offshore funds, which are classified as long-term investments and are accounted for using the equity method of accounting based on our ownership interest in each fund.

Inventory

Inventory is stated at the lower of cost or market. Cost is determined using the first-in, first-out method and includes the cost of materials, labor and manufacturing overhead. Inventory included the following:

Our aircraft logistics operations in Canada recognized $4.9 million and $4.6 million in operating revenues, which resulted in losses of $1.0 million and $1.5 million, net of tax benefits of $.3 million and $.5 million, during the three months ended March 31, 2012 and 2011, respectively. The assets are included in our Other Rig Services Operating segment.

intend to sell these investments, and it is less likely than not that we will be required to sell them to satisfy our own cash flow and working capital requirements. We believe that we will be able to collect all amounts due according to the contractual terms of each investment and, therefore, do not consider the decline in value of these investments to be other-than-temporary at March 31, 2012.

Note 5    Fair Value Measurements

The following table sets forth, by level within the fair value hierarchy, our financial assets and liabilities that are accounted for at fair value on a recurring basis as of March 31, 2012. Our debt securities could transfer into or out of a Level 1 or 2 measure depending on the availability of independent and current pricing at the end of each quarter. During the three months ended March 31, 2012, there were no transfers of our financial assets and liabilities between Level 1 and Level 2 measures. Our financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

Nonrecurring Fair Value Measurements

Fair value measurements were applied with respect to our nonfinancial assets and liabilities measured on a nonrecurring basis, which would consist of measurements primarily to goodwill, intangible assets and other long-lived assets, assets acquired and liabilities assumed in a business combination, and asset retirement obligations.

Fair Value of Financial Instruments

The fair value of our financial instruments has been estimated in accordance with GAAP. The fair value of our long-term debt and subsidiary preferred stock is estimated based on quoted market prices or prices quoted from third-party financial institutions. The carrying and fair values of these liabilities were as follows:

(1) Includes $.2 million and $.3 million as of March 31, 2012 and December 31, 2011, respectively, related to the unamortized loss on the interest rate swap that was unwound during the fourth quarter of 2005.

(2) Fair value represents a Level 2 measure.

(3) Fair value represents a Level 1 measure.

The fair values of our cash equivalents, trade receivables and trade payables approximate their carrying values due to the short-term nature of these instruments.

As of March 31, 2012, our short-term investments were carried at fair market value and included $122.3 million and $17.6 million in securities classified as available-for-sale and trading, respectively. As of December 31, 2011, our short-term investments were carried at fair market value and included $129.3 million and $11.6 million in securities classified as available-for-sale and trading, respectively.

Note 6    Share-Based Compensation

We have several share-based employee compensation plans, which are more fully described in Note 8 Share-Based Compensation to the audited financial statements included in our 2011 Annual Report. Total share-based compensation expense, which includes both stock options and restricted stock, totaled $4.5 million and $3.9 million for the three months ended March 31, 2012 and 2011, respectively, and is included in direct costs and general and administrative expenses in our consolidated statements of income (loss). Share-based compensation expense has been allocated to our various operating segments. See Note 14 — Segment Information.

During the three months ended March 31, 2012 and 2011, we awarded 907,786 and 782,708 shares of restricted stock, respectively, vesting over periods up to four years, to our employees and directors. These awards had an aggregate value at their grant date of $19.0 million and $21.2 million, respectively. The fair value of restricted stock that vested during the three months ended March 31, 2012 and 2011 was $8.2 million and $12.4 million, respectively.

14

The total intrinsic value of stock options exercised during the three months ended March 31, 2012 and 2011 was $4.9 million and $11.3 million, respectively. Additionally, the intrinsic value of stock options surrendered during the three months ended March 31, 2012 was $17.9 million. The total fair value of stock options that vested during the three months ended March 31, 2012 and 2011 was $7.5 million and $5.1 million, respectively.

Note 7    Investments in Unconsolidated Affiliates

We have several unconsolidated affiliates that are integral to our operations. For a full description, refer to Note 10 — Investments in Unconsolidated Affiliates in our 2011 Annual Report.

As of March 31, 2012 and December 31, 2011, our consolidated balance sheets reflect our investments in unconsolidated affiliates accounted for using the equity method totaling $303.1 million and $371.0 million, respectively. Assets held for sale include investments in unconsolidated affiliates accounted for using the equity method totaling $13.7 million at March 31, 2012 and December 31, 2011, respectively.

5.375% Senior Notes Due August 2012

At December 31, 2011, the current portion of our long-term debt included Nabors Delaware’s 5.375% senior notes of $274.6 million. We intend to utilize cash on hand and capacity under our revolving credit facilities to meet this obligation.

15

Revolving Credit Facilities

As of March 31, 2012, we had $390 million of remaining availability from a combined total of $1.4 billion under our existing revolving credit facilities. The existing revolving credit facilities mature in September 2014, and can be used for general corporate purposes, including capital expenditures and working capital. The weighted average interest rate on borrowings at March 31, 2012 was 1.75%. We fully and unconditionally guarantee the obligations under all of these credit facilities.

The revolving credit facilities contain various covenants and restrictive provisions that limit our ability to incur additional indebtedness, make investments or loans and create liens and require us to maintain a net funded indebtedness to total capitalization ratio, as defined in each agreement. We were in compliance with all covenants under the agreements at March 31, 2012 and December 31, 2011. If we should fail to perform our obligations under the covenants, the revolving credit commitments could be terminated and any outstanding borrowings under the relevant facility could be declared immediately due and payable.

Note 9    Common Shares

During the three months ended March 31, 2012, our employees exercised vested options and surrendered unexercised vested stock options to acquire 1.0 million of our common shares. We received proceeds of $15.7 million from exercised vested options and used approximately $21.0 million, the value of the unexercised vested options that were surrendered, to satisfy some of the option exercise price and related tax withholding obligations pursuant to stock option share settlements and exercises by some of the employees. During the three months ended March 31, 2011, our employees exercised vested options to acquire .8 million of our common shares, resulting in proceeds of $9.4 million. For each of the three months ended March 31, 2012 and 2011, we withheld .1 million of our common shares with a fair value of $1.8 million and $2.3 million, respectively, to satisfy tax withholding obligations in connection with the vesting of all stock awards.

At December 31, 2011, accrued liabilities included a provision of $100 million for a contingent liability related to the change of our Chief Executive Officer that occurred in October 2011. In February 2012, our former Chief Executive Officer elected to forego triggering that payment. In connection with that development, we announced plans to make charitable contributions to benefit the needs of our employees and other community-based causes. During the first quarter of 2012, we contributed one million of our treasury shares to the Nabors Charitable Foundation, a 501(c)(3) organization, in support of this objective. We consider the former Chief Executive Officer to be a significant shareholder of the Company and, therefore, have recorded these transactions as equity. We recorded the release of the contingent liability, net of tax, through capital in excess of par as a forgiveness of liability from a beneficial owner. We recorded the donation of the treasury shares at their weighted-average cost, net of tax, through capital in excess of par.

Note 10    Subsidiary Preferred Stock

As of and during the three months ended March 31, 2012, dividends of $.75 million on outstanding shares of preferred stock had been declared and paid in full.

Note 11    Commitments and Contingencies

Commitments

Employment Contracts

The employment agreement for Mr. Petrello currently provides for a term through March 30, 2015, with automatic one-year extensions each April 1, unless either party gives notice of nonrenewal. In the event of Mr. Petrello’s termination without cause or constructive termination without cause, he would be entitled to receive three times the average of his base salary and annual bonus during the three fiscal years preceding the

16

termination. If, by way of example, Mr. Petrello were terminated without cause subsequent to March 31, 2012, his payment would be approximately $31.1 million. The formula will be further reduced to two times the average stated above in April 1, 2015. In the event of his death or disability, either he or his estate would be entitled to receive within 30 days thereafter a payment of $50 million.

We do not have insurance to cover, and we have not recorded an expense or accrued a liability relating to this potential obligation. See Note 18 Commitments and Contingencies to our 2011 Annual Report for additional discussion and description of Mr. Petrello’s employment agreement.

Contingencies

Income Tax Contingencies

We are subject to income taxes in the United States and numerous other jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. We are regularly audited by tax authorities. Although we believe our tax estimates are reasonable, the final determination of tax audits and any related litigation could be materially different than what is reflected in income tax provisions and accruals. An audit or litigation could materially affect our financial position, income tax provision, net income, or cash flows in the period or periods challenged.

It is possible that future changes to tax laws (including tax treaties) could impact our ability to realize the tax savings recorded to date as well as future tax savings, resulting from our 2002 corporate reorganization. See Note 13 — Income Taxes to our 2011 Annual Report for additional discussion.

On September 14, 2006, Nabors Drilling International Limited, one of our wholly owned Bermuda subsidiaries (“NDIL”), received a Notice of Assessment from Mexico’s federal tax authorities in connection with the audit of NDIL’s Mexico branch for 2003. The notice proposes to deny depreciation expense deductions relating to drilling rigs operating in Mexico in 2003. The notice also proposes to deny a deduction for payments made to an affiliated company for the procurement of labor services in Mexico. The amount assessed was approximately $19.8 million (including interest and penalties). Nabors and its tax advisors previously concluded that the deductions were appropriate. NDIL’s Mexico branch took similar deductions for depreciation and labor expenses from 2004 to 2008. On June 30, 2009, the government proposed similar assessments against the Mexico branch of another wholly owned Bermuda subsidiary, Nabors Drilling International II Ltd. (“NDIL II”) for 2006. We anticipate that a similar assessment will eventually be proposed against NDIL for 2005 through 2008 and against NDIL II for 2007 to 2010. We believe that the potential assessments will range from $6 million to $26 million per year for the period from 2005 to 2009, and in the aggregate, would be approximately $90 million to $95 million. Although Nabors and our tax advisors previously concluded that the deductions were appropriate for the 2003 and 2005 to 2010 years, a reserve has been recorded in accordance with GAAP. The statute of limitations for NDIL’s 2004 tax year expired. Accordingly, during the fourth quarter of 2010, we released $7.4 million from our tax reserves, which represented the reserve recorded for that tax year. If these additional assessments were made and we ultimately did not prevail, we would be required to recognize additional tax for the amount in excess of the current reserve.

Self-Insurance

We estimate the level of our liability related to insurance and record reserves for these amounts in our consolidated financial statements. Our estimates are based on the facts and circumstances specific to existing claims and our past experience with similar claims. These loss estimates and accruals recorded in our financial statements for claims have historically been reasonable in light of the actual amount of claims paid. Although we believe our insurance coverage and reserve estimates are reasonable, a significant accident or other event that is not fully covered by insurance or contractual indemnity could occur and could materially affect our financial position and results of operations for a particular period.

17

Effective April 1, 2012, our workers’ compensation claims are subject to a $2.0 million per-occurrence deductible, and our automobile claims are subject to a $1.0 million per-occurrence deductible.

Litigation

Nabors and its subsidiaries are defendants or otherwise involved in a number of lawsuits in the ordinary course of business. We estimate the range of our liability related to pending litigation when we believe the amount and range of loss can be estimated. We record our best estimate of a loss when the loss is considered probable. When a liability is probable and there is a range of estimated loss with no best estimate in the range, we record the minimum estimated liability related to the lawsuits or claims. As additional information becomes available, we assess the potential liability related to our pending litigation and claims and revise our estimates. Due to uncertainties related to the resolution of lawsuits and claims, the ultimate outcome may differ from our estimates. For matters where an unfavorable outcome is reasonably possible and significant, we disclose the nature of the matter and a range of potential exposure, unless an estimate cannot be made at the time of disclosure. In the opinion of management and based on liability accruals provided, our ultimate exposure with respect to these pending lawsuits and claims is not expected to have a material adverse effect on our consolidated financial position or cash flows, although they could have a material adverse effect on our results of operations for a particular reporting period.

On July 5, 2007, we received an inquiry from the U.S. Department of Justice relating to its investigation of one of our vendors and compliance with the Foreign Corrupt Practices Act. The inquiry relates to transactions with and involving Panalpina, which provided freight forwarding and customs clearance services to some of our affiliates. The inquiry focused on transactions in Kazakhstan, Saudi Arabia, Algeria and Nigeria. The Audit Committee of our Board of Directors engaged outside counsel to review some of our transactions with this vendor, received periodic updates at its regularly scheduled meetings, and the Chairman of the Audit Committee received updates between meetings as circumstances warranted. The investigation included a review of certain amounts paid to and by Panalpina in connection with obtaining permits for the temporary importation of equipment and clearance of goods and materials through customs. Both the SEC and the Department of Justice have been advised of the results of our investigation. The SEC recently advised us that it has concluded its review of this matter and does not intend to recommend any enforcement action against us. Although the Department of Justice has not concluded its inquiry, we do not anticipate that its final determination will have an adverse effect on the Company.

A court in Algeria entered a judgment of approximately $19.7 million against us related to alleged customs infractions in 2009. We believe we did not receive proper notice of the judicial proceedings, and that the amount of the judgment is excessive. We have asserted the lack of legally required notice as a basis for challenging the judgment on appeal to the Algeria Supreme Court. Based upon our understanding of applicable law and precedent, we believe that this challenge will be successful. We do not believe that a loss is probable and have not accrued any amounts related to this matter. The Algeria Supreme Court has notified us that it will deliver its decision in the second quarter of 2012. If we are ultimately required to pay a fine or judgment related to this matter, the amount of the loss could range from approximately $140,000 to $19.7 million.

In March 2011, the Court of Ouargla (in Algeria), sitting at first instance, entered a judgment of approximately $39.1 million against us relating to alleged violations of Algeria’s foreign currency exchange controls, which require that goods and services provided locally be invoiced and paid in local currency. The case relates to certain foreign currency payments made to us by CEPSA, a Spanish operator, for wells drilled in 2006. Approximately $7.5 million of the total contract amount was paid offshore in foreign currency, and approximately $3.2 million was paid in local currency. The judgment includes fines and penalties of approximately four times the amount at issue, and is not payable pending appeal. We have appealed the ruling based on our understanding that the law in question applies only to resident entities incorporated under Algerian law. An intermediate court of appeals has upheld the lower court’s ruling, and we have appealed the matter to the Algeria Supreme Court. While our payments were consistent with our historical operations in the country and,

18

we believe, those of other multinational corporations there, and interpretations of the law by the Central Bank of Algeria, the ultimate resolution of this matter could result in a loss of up to $31.1 million in excess of amounts accrued.

On September 21, 2011, we received an informal inquiry from the SEC related to perquisites and personal benefits received by the officers and directors of Nabors, including their use of non-commercial aircraft. Our Audit Committee and Board of Directors have been apprised of this inquiry and we are cooperating with the SEC. The ultimate outcome of this process cannot be determined at this time.

Nabors Industries Ltd. and its Board of Directors have been sued in three separate purported shareholder derivative lawsuits filed in federal and state court in Houston, Texas. The cases were filed on November 18, 2011, January 9, 2012, and November 30, 2011, respectively, before Judges Ewing Werlein and Gray Miller in the United States Southern District of Texas, Houston Division, and Judge Mike Miller of the 11th Judicial District Court of Harris County, Texas. The case pending before Judge Gray Miller was voluntarily dismissed on January 31, 2012. The other cases remain pending. The allegations of each lawsuit are substantially similar, alleging that the members of the Board breached their fiduciary duties to the Company, wasted corporate assets, and committed oppressive conduct against the shareholders by agreeing to acquiesce to certain compensation arrangements with two senior officers of the Company, Eugene M. Isenberg and Anthony G. Petrello. The remaining lawsuits seek relief that includes an award of monetary damages in an unspecified amount, disgorgement by Messrs. Isenberg and Petrello of allegedly excessive compensation in an unspecified amount of at least $90 million, and equitable relief to reform Nabors’ compensation practices. Nabors intends to vigorously defend the lawsuits and has filed a motion to dismiss the remaining federal court lawsuit. The ultimate outcome of these lawsuits cannot be determined at this time.

On March 9, 2012, Nabors Global Holdings II Limited (“NGH2L”) signed a contract with ERG Resources, LLC (“ERG”) relating to the sale of all of the Class A shares of NGH2L’s wholly owned subsidiary, Ramshorn International Limited, an oil and gas exploration company. When ERG failed to meet its closing obligations, NGH2L terminated the transaction on March 19, 2012 and, as contemplated in the agreement, retained ERG’s $3 million escrow deposit. ERG filed suit the following day in the 61^st Judicial District Court of Harris County, Texas, in a case styledERG Resources, LLC v. Nabors Global Holdings II Limited, Ramshorn International Limited,andParex Resources, Inc.;Cause No. 2012-16446, seeking injunctive relief to halt any sale of the shares to a third party, specifically naming as defendant Parex Resources, Inc. (“Parex”). The lawsuit also seeks monetary damages of up to $100 million based on an alleged breach of contract by NGH2L and tortious interference with contractual relations by Parex. Nabors successfully defeated ERG’s effort to obtain a temporary restraining order from the Texas court on March 20, 2012. On March 23, 2012, ERG filed and obtained anex parte stay from the Supreme Court of Bermuda (Commercial Court), in a case styled asERG Resources LLC v. Nabors Global Holdings II Limited, Case No. 2012: No. 110. Nabors challenged the stay and, following a series of oral hearings on the matter, the Bermuda court discharged the stay by a ruling dated April 5, 2012. Nabors completed the sale of Ramshorn’s Class A shares to a Parex affiliate on April 12, 2012, which mooted ERG’s application for a temporary injunction that was scheduled for hearing by the Texas court on April 13, 2012. ERG retains its causes of action for monetary damages, but Nabors believes the claims are foreclosed by the terms of the agreement and are without factual or legal merit. While Nabors intends to vigorously defend the lawsuit, the ultimate outcome of the lawsuit cannot be determined at this time.

Off-Balance Sheet Arrangements (Including Guarantees)

We are a party to some transactions, agreements or other contractual arrangements defined as “off-balance sheet arrangements” that could have a material future effect on our financial position, results of operations, liquidity and capital resources. The most significant of these off-balance sheet arrangements involve agreements and obligations under which we provide financial or performance assurance to third parties. Certain of these agreements serve as guarantees, including standby letters of credit issued on behalf of insurance carriers in conjunction with our workers’ compensation insurance program and other financial surety instruments such as

19

bonds. In addition, we have provided indemnifications, which serve as guarantees, to some third parties. These guarantees include indemnification provided by Nabors to our share transfer agent and our insurance carriers. We are not able to estimate the potential future maximum payments that might be due under our indemnification guarantees.

Management believes the likelihood that we would be required to perform or otherwise incur any material losses associated with any of these guarantees is remote. The following table summarizes the total maximum amount of financial guarantees issued by Nabors:

	Maximum Amount
	Remainder of 2012		2013		2014		Thereafter		Total

Note 12    Earnings (Losses) Per Share

A reconciliation of the numerators and denominators of the basic and diluted earnings (losses) per share computations is as follows:

	Three Months Ended March 31,
	2012			2011
	(In thousands, except share amounts)
Net income (loss) (numerator):
Income (loss) from continuing operations, net of tax	$	142,618		$	94,552
Less: net (income) loss attributable to noncontrolling interest		267			669
Adjusted income (loss) from continuing operations, net of tax — basic		142,885			95,221
Add interest expense on assumed conversion of 0.94% senior exchangeable notes, net of tax(1)		—			—
Adjusted income (loss) from continuing operations, net of tax — diluted		142,885			95,221
Income (loss) from discontinued operations, net of tax		(8,795	)		(12,396	)
Adjusted net income (loss) attributable to Nabors		134,090			82,825
Earnings (losses) per share:	$	.50		$	.33
Basic from continuing operations		(.04	)		(.04	)
Basic from discontinued operations	$	.46		$	.29
Total Basic
Diluted from continuing operations	$	.49		$	.33
Diluted from discontinued operations		(.03	)		(.05	)
Total Diluted	$	.46		$	.28
Shares (denominator):		288,538			286,114
Weighted-average number of shares outstanding — basic		3,171			6,575
Net effect of dilutive stock options, warrants and restricted stock awards based on the if-converted method		—			—
Assumed conversion of 0.94% senior exchangeable notes(1)		—			—
Weighted-average number of shares outstanding — diluted		291,709			292,689

(1) At maturity in May 2011, we redeemed the remaining aggregate principal amount of $1.4 billion of our 0.94% senior exchangeable notes. Prior to maturity, we had purchased $1.4 billion par value of these notes

20

in the open market for cash of $1.2 billion. Diluted earnings (losses) per share for the three months ended March 31, 2011 exclude any incremental shares that would have been issuable upon exchange of these notes based on a calculation using our stock price. Our stock price did not exceed the threshold during the three months ended March 31, 2011.

For all periods presented, the computation of diluted earnings (losses) per Nabors’ share excludes outstanding stock options and warrants with exercise prices greater than the average market price of Nabors’ common shares, because their inclusion would be anti-dilutive and because they are not considered participating securities. The average number of options and warrants that were excluded from diluted earnings (losses) per share that would potentially dilute earnings per share in the future was 11,763,048 and 7,269,039 shares during the three months ended March 31, 2012 and 2011, respectively. In any period during which the average market price of Nabors’ common shares exceeds the exercise prices of these stock options and warrants, such stock options and warrants will be included in our diluted earnings (losses) per share computation using the if-converted method of accounting. Restricted stock will be included in our basic and diluted earnings (losses) per share computation using the two-class method of accounting in all periods because such stock is considered a participating security.

(1) All periods present the operating activities of our wholly owned oil and gas business in the United States, Canada and Colombia, including equity interests in Canada and Colombia, as well as our aircraft logistics operations in Canada as discontinued operations.

(2) Includes our drilling technology and top drive manufacturing, directional drilling, rig instrumentation and software, and construction services. These services represent our other companies that are not aggregated into a reportable operating segment.

(3) Includes earnings (losses), net from unconsolidated affiliates, accounted for using the equity method, of $(6.1) million and $1.1 million for the three months ended March 31, 2012 and 2011, respectively.

(4) Includes earnings (losses), net from unconsolidated affiliates, accounted for using the equity method, of $(62.6) million and $15.2 million for the three months ended March 31, 2012 and 2011, respectively.

(5) Represents the elimination of inter-segment transactions.

(6) Adjusted income (loss) derived from operating activities is computed by subtracting direct costs, general and administrative expenses, and depreciation and amortization from Operating revenues and then adding Earnings (losses) from unconsolidated affiliates (excluding our proportionate share of full-cost ceiling test writedowns recorded by our oil and gas joint venture). These amounts should not be used as a substitute for those amounts reported in accordance with GAAP. However, management evaluates the performance of our business units and the consolidated company based on several criteria, including adjusted income (loss) derived from operating activities, because it believes that these financial measures accurately reflect our ongoing profitability. A reconciliation of this non-GAAP measure to income (loss) from continuing operations before income taxes, which is a GAAP measure, is provided in the above table.

(7) Includes earnings (losses), net from unconsolidated affiliates, accounted for using the equity method, of $5.6 million (excluding $68.2 million, which represents our proportionate share of full-cost ceiling test writedowns by our oil and gas joint venture) and $15.2 million for the three months ended March 31, 2012 and 2011, respectively.

(8) Represents the elimination of inter-segment transactions and unallocated corporate expenses, and assets.

(9) Includes $68.8 million and $76.9 million of investments in unconsolidated affiliates accounted for using the equity method as of March 31, 2012 and December 31, 2011, respectively.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders

of Nabors Industries Ltd.:

We have reviewed the accompanying consolidated balance sheet of Nabors Industries Ltd. and its subsidiaries (the “Company”) as of March 31, 2012, and the related consolidated statements of income and other comprehensive income for the three-month periods ended March 31, 2012 and March 31, 2011 and the consolidated statements of cash flows and of changes in equity for the three-month periods ended March 31, 2012 and March 31, 2011. This interim financial information is the responsibility of the Company’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the accompanying consolidated interim financial information for it to be in conformity with accounting principles generally accepted in the United States of America.

We previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet as of December 31, 2011, and the related consolidated statements of income, changes in equity and of cash flows for the year then ended (not presented herein), and in our report dated February 29, 2012, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated balance sheet information as of December 31, 2011, is fairly stated in all material respects in relation to the consolidated balance sheet from which it has been derived.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

FORWARD-LOOKING STATEMENTS

We often discuss expectations regarding our future markets, demand for our products and services, and our performance in our annual and quarterly reports, press releases, and other written and oral statements. Statements relating to matters that are not historical facts are “forward-looking statements” within the meaning of the safe harbor provisions of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). These “forward-looking statements” are based on an analysis of currently available competitive, financial and economic data and our operating plans. They are inherently uncertain and investors should recognize that events and actual results could turn out to be significantly different from our expectations. By way of illustration, when used in this document, words such as “anticipate,” “believe,” “expect,” “plan,” “intend,” “estimate,” “project,” “will,” “should,” “could,” “may,” “predict” and similar expressions are intended to identify forward-looking statements.

You should consider the following key factors when evaluating these forward-looking statements:

• fluctuations in worldwide prices of and demand for natural gas and oil;

• fluctuations in levels of natural gas and oil exploration and development activities;

• fluctuations in the demand for our services;

• the existence of competitors, technological changes and developments in the oilfield services industry;

• the existence of operating risks inherent in the oilfield services industry;

• the possibility of changes in tax and other laws and regulations;

• the possibility of political instability, war or acts of terrorism; and

• general economic conditions including the capital and credit markets.

Our businesses depend to a large degree on the level of spending by oil and gas companies for exploration, development and production activities. Therefore, a sustained increase or decrease in the price of natural gas or oil that has a material impact on exploration, development or production activities could also materially affect our financial position, results of operations and cash flows.

The above description of risks and uncertainties is by no means all-inclusive, but is designed to highlight what we believe are important factors to consider. For a more detailed description of risk factors, please refer to Part I, Item 1A. —Risk Factorsin our 2011 Annual Report.

Management Overview

The following discussion and analysis is intended to help the reader understand the results of our operations and our financial condition. This information is provided as a supplement to, and should be read in conjunction with, our consolidated financial statements and the accompanying notes thereto.

The majority of our business is conducted through our Drilling and Other Rig Services and our Completion and Production Services business lines. Our Drilling and Other Rig Services business line includes our drilling of oil and natural gas wells, on land and offshore, and companies engaged in drilling technology, top drive manufacturing, directional drilling, construction services, and rig instrumentation and software. Our Completion and Production Services business line includes our well-servicing, fluid logistics, workover operations and our pressure pumping services. In addition to these two primary business lines, we have an Oil and Gas Operating segment. Our oil and gas exploration, development and production operations are included in our Oil and Gas Operating segment, or in discontinued operations in some cases.

35

The magnitude of customer spending on new and existing wells is the primary driver of our business. Our customers’ spending is determined principally by their internally generated cash flow and to a lesser extent by joint venture arrangements and funding from the capital markets. In our Drilling and Rig Services business lines, operations have traditionally been driven by natural gas prices, but the majority of current activity is being driven by the price of oil and natural gas liquids from unconventional reservoirs (shales). In our Completion and Production Services business line, operations are primarily driven by oil prices. The Henry Hub natural gas spot price (per Bloomberg) averaged $3.57 per thousand cubic feet (mcf) during the 12-month period ended March 31, 2012, down from $4.15 per mcf average during the prior 12 months. West Texas intermediate spot crude oil prices (per Bloomberg) averaged $97.15 per barrel for the 12 months ended March 31, 2012, up from $83.33 per barrel average during the preceding 12 months.

Operating revenues and Earnings (losses) from unconsolidated affiliates for the three months ended March 31, 2012 totaled $1.8 billion, representing an increase of $431.9 million, or 31% as compared to the three months ended March 31, 2011. Adjusted income derived from operating activities and net income (loss) from continuing operations for the three months ended March 31, 2012 totaled $321.2 million and $142.6 million ($.49 per diluted share), respectively, representing increases of 55% and 51%, respectively, compared to the three months ended March 31, 2011.

During the three months ended March 31, 2012, operating results improved as a result of increased demand for our services and products due to increased drilling activity in oil- and liquids-rich shale plays and increased well-servicing activity in the U.S. and Canada. This has more than offset the drop in demand from gas-related plays. Our net income was negatively impacted as a result of a full-cost ceiling test writedown by our unconsolidated U.S. oil and gas joint venture. The writedown is included in our Oil and Gas Operating segment results.

The lower price environment for natural gas has reduced activity in our gas-driven markets and is adversely impacting our pressure pumping business as the reduced activity has created a sooner than anticipated oversupply of pumping equipment. Directionally, similar forces are at work on land drilling in gas-driven markets but to a lesser degree. We anticipate a protracted weak spot market in pressure pumping operations and flat to slightly lower industry rig activity throughout 2012. While the U.S. Land Drilling and Pressure Pumping operating segments face these headwinds, we expect healthy operations in our remaining segments for the remainder of the year. The key factors supporting our views are:

• The current term contracts in both our Lower 48 Land Drilling rig and Pressure Pumping Operating segments, combined with new and contracted rig deployments in 2012, will mitigate to a degree the continued reduction in gas drilling activity arising from weaker natural gas pricing;

• The increased activity expected in our International operations throughout the year as the result of new contracts for the rig deployments in international markets; and

• Further, an expected gradual improvement in our U.S. Offshore results as the pace of permits issuance improves as contribution from two new platform construction projects increase throughout 2012 and commence operating in early 2013.

(1) All periods present the operating activities of our wholly owned oil and gas business in the United States, Canada and Colombia, including equity interests in Canada and Colombia, as well as our aircraft logistics operations in Canada as discontinued operations.

(2) Includes our drilling technology and top drive manufacturing, directional drilling, rig instrumentation and software, and construction services. These services represent our other companies that are not aggregated into a reportable operating segment.

(3) Includes earnings (losses), net from unconsolidated affiliates, accounted for using the equity method, of $(6.1) million and $1.1 million for the three months ended March 31, 2012 and 2011, respectively.

(4) Includes earnings (losses), net from unconsolidated affiliates, accounted for using the equity method, of $(62.6) million and $15.2 million for the three months ended March 31, 2012 and 2011, respectively.

(5) Represents the elimination of inter-segment transactions.

(6) Adjusted income (loss) derived from operating activities is computed by subtracting direct costs, general and administrative expenses, and depreciation and amortization from Operating revenues and then adding Earnings (losses) from unconsolidated affiliates (excluding our proportionate share of full-cost ceiling test writedowns recorded by our oil and gas joint venture). These amounts should not be used as a substitute for those amounts reported in accordance with GAAP. However, management evaluates the performance of our business units and the consolidated company based on several criteria, including adjusted income (loss) derived from operating activities, because it believes that these financial measures accurately reflect our ongoing profitability. A reconciliation of this non-GAAP measure to income (loss) from continuing operations before income taxes, which is a GAAP measure, is provided in the above table.

(7) Includes earnings (losses), net from unconsolidated affiliates, accounted for using the equity method, of $5.6 million (excluding $68.2 million, which represents our proportionate share of full-cost ceiling test writedowns by our oil and gas joint venture) and $15.2 million for the three months ended March 31, 2012 and 2011, respectively.

(8) Represents the elimination of inter-segment transactions and unallocated corporate expenses.

(9) Excludes well-servicing rigs, which are measured in rig hours. Includes our equivalent percentage ownership of rigs owned by unconsolidated affiliates. Rig years represent a measure of the number of equivalent rigs operating during a given period. For example, one rig operating 182.5 days during a 365-day period represents 0.5 rig years.

(10) International rig years include our equivalent percentage ownership of rigs owned by unconsolidated affiliates, which totaled 2.5 years and 2.0 years during the three months ended March 31, 2012 and 2011, respectively.

(11) Rig hours represents the number of hours that our well-servicing rig fleet operated during the specified periods.

Segment Results of Operations

Drilling and Rig Services

Our Drilling and Rig Services operations contain one or more of the following operations: drilling on land and offshore, drilling technology, top drive manufacturing, directional drilling, construction services, and rig instrumentation and software.

U.S. Lower 48 Land Drilling.The results of operations for this segment were as follows:

	Three Months Ended March 31,
(In thousands, except percentages and rig activity)	2012		2011		Increase (Decrease)
Operating revenues	$	495,697	$	378,568	$	117,129	31	%
Adjusted income derived from operating activities	$	131,581	$	80,095	$	51,486	64	%
Rig years		219.0		187.9		31.1	17	%

Operating results increased during the three months ended March 31, 2012 compared to the corresponding 2011 quarter primarily due to higher average dayrates and increased drilling activity, driven by deployment of rigs into oil-rich shale areas. The increase was partially offset by an increase in operating costs associated with drilling activity, as well as higher depreciation expense related to new rigs placed into service since January 2010.

U.S. Offshore.The results of operations for this segment were as follows:

	Three Months Ended March 31,
(In thousands, except percentages and rig activity)	2012		2011			Increase (Decrease)
Operating revenues	$	69,115	$	30,454		$	38,661	127	%
Adjusted income (loss) derived from operating activities	$	7,732	$	(3,977	)	$	11,709	294	%
Rig years		11.9		8.0			3.9	49	%

Operating results increased during the three months ended March 31, 2012 compared to the corresponding 2011 quarter resulting primarily from higher utilization for the MODS^® rigs, SuperSundowner^TM platform rigs, and workover jackup rigs, as well as from profits related to a major construction project. Demand for our rigs has increased substantially as operators have obtained the proper permits for drilling operations in the Gulf of Mexico, the issuance of which had been subject to a lengthy and stringent review process since the Maconda blowout in the Gulf of Mexico in mid-2010.

Alaska.The results of operations for this segment were as follows:

	Three Months Ended March 31,
(In thousands, except percentages and rig activity)	2012		2011		Increase (Decrease)
Operating revenues	$	62,293	$	41,315	$	20,978	51	%
Adjusted income (loss) derived from operating activities	$	27,420	$	11,019	$	16,401	149	%
Rig years		8.2		5.3		2.9	55	%

The increase in operating results during the three months ended March 31, 2012 compared to the corresponding 2011 quarter was due to higher average dayrates and increased drilling activity, driven primarily by an overall increase in winter exploration activity in the first quarter of 2012.

39

Canada.The results of operations for this segment were as follows:

	Three Months Ended March 31,
(In thousands, except percentages and rig activity)	2012		2011		Increase (Decrease)
Operating revenues	$	192,293	$	172,443	$	19,850		12	%
Adjusted income (loss) derived from operating activities	$	49,287	$	38,992	$	10,295		26	%
Rig years		48.7		49.7		(1.0	)	(2	%)
Rig hours — Canada		57,044		53,154		3,890		7	%

Operating results increased during the three months ended March 31, 2012 as compared to the corresponding 2011 quarter as a result of an overall increase in average dayrates, particularly in Western Canada, driven by renewed interest in oil exploration, supported by strong oil commodity prices.

International.The results of operations for this segment were as follows:

	Three Months Ended March 31,
(In thousands, except percentages and rig activity)	2012		2011		Increase (Decrease)
Operating revenues and Earnings from unconsolidated affiliates	$	306,465	$	262,477	$	43,988		17	%
Adjusted income derived from operating activities	$	21,138	$	35,497	$	(14,359	)	(40	%)
Rig years		117.7		99.6		18.1		18	%

Operating revenues and Earnings from unconsolidated affiliates increased during the three months ended March 31, 2012 as compared to the corresponding 2011 quarter as a result of an increase in the utilization of our overall rig fleet, partially offset by lower margins. Adjusted income derived from operating activities decreased during the three months ended March 31, 2012 as compared to the corresponding prior year quarter primarily due to decreases in average dayrates and lower utilization of our jackup rigs in Saudi Arabia, lower offshore activity in Congo, and the incurrence of start-up costs in Iraq.

Other Rig Services.The results of operations for this segment were as follows:

	Three Months Ended March 31,
(In thousands, except percentages and rig activity)	2012		2011		Increase (Decrease)
Operating revenues and Earnings from unconsolidated affiliates	$	241,758	$	116,789	$	124,969	107	%
Adjusted income (loss) derived from operating activities	$	29,846	$	8,344	$	21,502	258	%

Operating results for our Canrig business increased during the three months ended March 31, 2012 as compared to the corresponding 2011 quarter primarily due to increased demand in the United States and Canada drilling markets. Our operating results reflect higher third-party rental of capital equipment and higher sales of RIGWATCH^TM software and ROCKIT^TM directional drilling systems, as well as higher top-drive rental sales.

Additionally, operating results increased for our construction and rig-moving business in Alaska as well as our directional drilling business during the three months ended March 31, 2012 as compared to the corresponding 2011 quarter primarily due to higher average dayrates in the U.S. and Canada. Operating costs in the U.S. remained consistent with 2011 levels, while operating costs in Canada decreased during the first quarter of 2012.

40

Completion and Production Services

Our Completion and Production Services operations contain one or more of the following operations in the U.S. and Canada: well-servicing, fluid logistics, workover operations and pressure pumping services.

U.S. Land Well-servicing.The results of operations for this segment were as follows:

	Three Months Ended March 31,
(In thousands, except percentages and rig activity)	2012		2011		Increase (Decrease)
Operating revenues	$	209,701	$	150,256	$	59,445	40	%
Adjusted income (loss) derived from operating activities	$	21,888	$	11,123	$	10,765	97	%
Rig hours — U.S.		213,026		187,581		25,445	14	%

Operating results increased during the three months ended March 31, 2012 compared to the corresponding 2011 quarter primarily due to an increase in rig and truck utilization facilitated by capital invested over the past few years to increase our rig and truck fleets as well as fracturing tank counts. Higher equipment utilization and price improvements were driven primarily by sustained higher oil prices.

Pressure Pumping.The results of operations for this segment were as follows:

	Three Months Ended March 31,
(In thousands, except percentages and rig activity)	2012		2011		Increase (Decrease)
Operating revenues	$	398,036	$	257,859	$	140,177	54	%
Adjusted income (loss) derived from operating activities	$	64,860	$	43,715	$	21,145	48	%

Operating results increased during the three months ended March 31, 2012 compared to the corresponding 2011 quarter primarily due to the increased levels of fracturing activity and associated increase in our assets deployed in the major producing areas in the United States.

Oil and Gas. The results from our U.S. oil and gas unconsolidated affiliate were as follows:

	Three Months Ended March 31,
(In thousands, except percentages)	2012			2011		Increase (Decrease)
Earnings from unconsolidated affiliate	$	(62,562	)	$	15,160	$	(77,722	)	(513	%)
Adjusted income derived from operating activities	$	5,650		$	15,160	$	(9,510	)	(63	%)

Earnings from unconsolidated affiliates decreased during the three months ended March 31, 2012 compared to the corresponding 2011 quarter primarily as a result of a full-cost ceiling test writedown during the first quarter of 2012, of which our proportionate share totaled $68.2 million. The writedown was partially offset by positive operating results during the first quarter of 2012 by this same joint venture. Adjusted income derived from operating activities excludes the calculation of the full-cost ceiling test writedown for the three months ended March 31, 2012. There was no such writedown during the three months ended March 31, 2011.

41

Discontinued Operations

Our condensed statements of income (loss) from discontinued oil and gas operations for the three months ended March 31, 2012 and 2011 were as follows:

Oil and Gas Operating Segment

	Three Months Ended March 31,
(In thousands, except percentages)	2012			2011			Increase (Decrease)
Operating revenues and Earnings from unconsolidated affiliates	$	3,301		$	11,419		$	(8,118	)	(71	%)
Income (loss) from discontinued operations

Income (loss) from discontinued operations, net of tax	$	(7,802	)	$	(10,876	)	$	3,074		28	%

On April 12, 2012, we sold our remaining wholly owned oil and gas operations in Colombia to an unrelated third party for a cash purchase price of $72.6 million. These assets were included in our assets held for sale as part of our Oil and Gas Operating segment and had a net book value of approximately $30.3 million.

Our aircraft logistics operations in Canada recognized $4.9 million and $4.6 million in operating revenues, which resulted in losses of $1.0 million and $1.5 million, net of tax benefits of $.3 million and $.5 million, during the three months ended March 31, 2012 and 2011, respectively. The assets are included in our Other Rig Services Operating segment.

OTHER FINANCIAL INFORMATION

General and administrative expenses

	Three Months Ended March 31,

General and administrative expenses as a percentage of operating revenues		7.2	%	$	8.4	%	$	(1.2	%)	(14	%)

General and administrative expenses increased during the three months ended March 31, 2012 compared to the corresponding 2011 quarter primarily as a result of increases in wages to support a higher headcount as a result of increased operations for a majority of our operating segments. As a percentage of operating revenues, general and administrative expenses decreased from the first quarter of 2012 to corresponding prior year quarter of 2011.

Depreciation and amortization

	Three Months Ended March 31,

Interest expense decreased during the three months ended March 31, 2012 compared to the corresponding 2011 quarter primarily as a result of the redemption in May 2011 of $1.4 billion 0.94% senior exchangeable notes. The decrease was partially offset by additional interest related to our August 2011 issuance of 4.625% senior notes due September 2021 and interest on amounts outstanding on our revolving credit facilities.

Investment income (loss)

	Three Months Ended March 31,
(In thousands, except percentages)	2012		2011		Increase (Decrease)
Investment income (loss)	$	20,252	$	12,280	$	7,972	65	%

Investment income for the three months ended March 31, 2012 included a $12.5 million realized gain related to the sale of some of our debt securities, net unrealized gains of $6.0 million from our trading securities and interest and dividend income of $1.4 million from our cash, other short-term and long-term investments.

Investment income for the three months ended March 31, 2011 included a $12.9 million realized gain related to one of our overseas fund investments classified as long-term investments and interest and dividend income of $1.8 million from our cash, other short-term and long-term investments, partially offset by net unrealized losses of $3.2 million from our trading securities.

Effective income tax rate from continuing operations		32	%		32	%		—	—

43

Our effective income tax rate during the three months ended March 31, 2012 is comparable to the corresponding 2011 quarter primarily because the proportion of income generated in the United States was consistent during each of these periods. Income generated in the United States is generally taxed at a higher rate than that of other jurisdictions.

We are subject to income taxes in the United States and numerous other jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes. One of the most volatile factors in this determination is the relative proportion of our income or loss being recognized in high- versus low-tax jurisdictions. In the ordinary course of our business, there are many transactions and calculations for which the ultimate tax determination is uncertain. We are regularly audited by tax authorities. Although we believe our tax estimates are reasonable, the final outcome of tax audits and any related litigation could be materially different than what is reflected in our income tax provisions and accruals. The results of an audit or litigation could materially affect our financial position, income tax provision, net income, or cash flows.

Various bills have been introduced in Congress that could reduce or eliminate the tax benefits associated with our reorganization as a Bermuda company. Legislation enacted by Congress in 2004 provides that a corporation that reorganized in a foreign jurisdiction on or after March 4, 2003 be treated as a domestic corporation for U.S. federal income tax purposes. Nabors’ reorganization was completed on June 24, 2002. There has been and we expect that there may continue to be legislation proposed by Congress from time to time which, if enacted, could limit or eliminate the tax benefits associated with our reorganization.

Because we cannot predict whether any legislation will ultimately be adopted, no assurance can be given that the tax benefits associated with our reorganization will ultimately accrue to the benefit of the Company and its shareholders. It is possible that future changes to the tax laws (including tax treaties) could impact our ability to realize the tax savings recorded to date as well as future tax savings resulting from our reorganization.

Liquidity and Capital Resources

Cash Flows

Our cash flows depend, to a large degree, on the level of spending by oil and gas companies for exploration, development and production activities. Sustained increases or decreases in the price of natural gas or oil could have a material impact on these activities, and could also materially affect our cash flows. Certain sources and uses of cash, such as the level of discretionary capital expenditures, purchases and sales of investments, issuances and repurchases of debt and of our common shares are within our control and are adjusted as necessary based on market conditions. The following is a discussion of our cash flows for the three months ended March 31, 2012 and 2011.

Operating Activities.    Net cash provided by operating activities totaled $244.2 million during the three months ended March 31, 2012 compared to net cash provided by operating activities of $290.9 million during the prior year corresponding 2011 quarter. Net cash provided by operating activities (“operating cash flows”) is our primary source of capital and liquidity. Factors affecting changes in operating cash flows are largely the same as those that affect net earnings, with the exception of non-cash expenses such as depreciation and amortization, depletion, impairments, share-based compensation, deferred income taxes and our proportionate share of earnings or losses from unconsolidated affiliates. Net income (loss) adjusted for non-cash components was approximately $479.5 million and $345.5 million for the three months ended March 31, 2012 and 2011, respectively. Additionally, changes in working capital items such as collection of receivables can be a significant factor in the determination of operating cash flows. Changes in working capital items used $235.4 million and $54.5 million, respectively, in cash flows for the three months ended March 31, 2012 and 2011.

Investing Activities.    Net cash used for investing activities totaled $429.7 million during the three months ended March 31, 2012 compared to net cash used for investing activities of $374.4 million during the prior year

44

corresponding 2011 quarter. The primary use of cash for investing activities is for capital expenditures related to rig-related enhancements, new construction and equipment, as well as sustaining capital expenditures. During the three months ended March 31, 2012 and 2011, we used cash for capital expenditures totaling $473.7 million and $358.6 million, respectively.

During the three months ended March 31, 2012, cash of $21.3 million was provided in proceeds from sales of assets and recoveries from insurance claims. During the three months ended March 31, 2012, cash of $23.5 million was provided from sales of investments. During the three months ended March 31, 2011, we provided cash of $19.0 million to our unconsolidated affiliates.

Financing Activities.    Net cash provided by financing activities totaled $139.5 million during the three months ended March 31, 2012 and consists primarily of amounts drawn from our revolving credit facilities. Net cash provided by financing activities was $9.1 million during the corresponding 2011 quarter.

Future Cash Requirements

We expect capital expenditures over the next 12 months to approximate $1.4 - 1.5 billion. We had outstanding purchase commitments of approximately $.9 billion at March 31, 2012, primarily for rig-related enhancements, new construction and equipment, as well as sustaining capital expenditures, other operating expenses and purchases of inventory. This amount could change significantly based on market conditions and new business opportunities. The level of our outstanding purchase commitments and our expected level of capital expenditures over the next 12 months represent a number of capital programs that are currently underway or planned. These programs will result in an expansion in the number of land drilling rigs, pressure pumping and well-servicing equipment that we own and operate. We can reduce the planned expenditures if necessary, or increase them if market conditions and new business opportunities warrant it.

We have historically completed a number of acquisitions and will continue to evaluate opportunities to acquire assets or businesses to enhance our operations. Several of our previous acquisitions were funded through issuances of debt or our common shares. Future acquisitions may be paid for using existing cash or by issuing debt or additional shares of our stock. Such capital expenditures and acquisitions will depend on our view of market conditions and other factors.

See our discussion of guarantees issued by Nabors that could have a potential impact on our financial position, results of operations or cash flows in future periods included below under Off-Balance Sheet Arrangements (Including Guarantees).

There have been no significant changes to our contractual cash obligations table which was included in our 2011 Annual Report.

We may from time to time seek to retire or purchase our outstanding debt through cash purchases and/or exchanges for equity securities, both in open-market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

See Note 18 — Commitments and Contingencies in our 2011 Annual Report for discussion of commitments and contingencies relating to (i) our employment agreement with Mr. Petrello that could result in a cash payment of $50 million by the Company if his employment were terminated in the event of his death or disability or a cash payment of approximately $31.1 million if his employment were terminated without cause or in the event of a change in control and (ii) off-balance sheet arrangements (including guarantees).

45

Financial Condition and Sources of Liquidity

Our primary sources of liquidity are operating cash flows, cash and cash equivalents, short-term and long-term investments and availability under our various revolving credit facilities. As of March 31, 2012, we had cash and short-term investments of $494.0 million and working capital of $1.5 billion. We also had $390 million of availability remaining from a combined total of $1.4 billion under revolving credit facilities. As of December 31, 2011, we had cash and short-term investments of $539.5 million and working capital of $1.3 billion.

We had six letter-of-credit facilities with various banks as of March 31, 2012. Availability under these facilities as of March 31, 2012 was as follows:

	(In thousands)
Credit available	$	215,900
Letters of credit outstanding, inclusive of financial and performance guarantees		(87,889	)
Remaining availability	$	128,011

Our revolving credit facilities contain various covenants and restrictive provisions that limit our ability to incur additional indebtedness, make investments or loans and create liens and require us to maintain the net funded indebtedness to total capitalization ratio, as defined in each agreement, at certain levels. We were in compliance with all covenants under the agreement at March 31, 2012.

Our ability to access capital markets or to otherwise obtain sufficient financing is enhanced by our senior unsecured debt ratings as provided by Fitch Ratings, Moody’s Investors Service and Standard & Poor’s and our historical ability to access those markets as needed. While there can be no assurances that we will be able to access these markets in the future, we believe that we will be able to access capital markets or otherwise obtain financing in order to satisfy any payment obligation that might arise upon exchange or purchase of our notes, payment of other debt and that any cash payment due, in addition to our other cash obligations, would not ultimately have a material adverse impact on our liquidity or financial position. A credit downgrade may impact our ability to access credit markets.

Our gross funded debt to capital ratio was 0.42:1 as of March 31, 2012 and 0.43:1 as of December 31, 2011. Our net funded debt to capital ratio was 0.40:1 as of March 31, 2012 and December 31, 2011.

The gross funded debt to capital ratio is calculated by dividing (x) funded debt by (y) funded debtplus deferred tax liabilities (net of deferred tax assets)plus capital. Funded debt is the sum of (1) short-term borrowings, (2) the current portion of long-term debt and (3) long-term debt. Capital is shareholders’ equity.

The net funded debt to capital ratio is calculated by dividing (x) net funded debt by (y) net funded debtplus deferred tax liabilities (net of deferred tax assets)plus capital. Net funded debt is funded debtminus the sum of cash and cash equivalents and short-term investments. Both of these ratios are used to calculate a company’s leverage in relation to its capital. Neither ratio measures operating performance or liquidity as defined by GAAP and, therefore, may not be comparable to similarly titled measures presented by other companies.

Our interest coverage ratio was 8.5:1 as of March 31, 2012 and 8.1:1 as of December 31, 2011. The interest coverage ratio is a trailing 12-month quotient of the sum of (x) income (loss) from continuing operations, net of tax, net income (loss) attributable to noncontrolling interest, interest expense, subsidiary preferred stock dividends, depreciation and amortization, income tax expense (benefit) and our proportionate share of writedowns from our unconsolidated oil and gas joint ventureless investment income (loss)dividedby (y) the sum of cash interest expense and subsidiary preferred stock dividends. This ratio is a method for calculating the amount of operating cash flows available to cover cash interest expense. The interest coverage ratio is not a measure of operating performance or liquidity defined by GAAP and may not be comparable to similarly titled measures presented by other companies.

46

Our current cash and investments, projected cash flows from operations, possible dispositions of non-core assets and our revolving credit facilities are expected to adequately finance our purchase commitments, scheduled debt service requirements, and all other expected cash requirements for the next 12 months.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We may be exposed to market risk through changes in interest rates and foreign-currency risk arising from our operations in international markets as discussed in our 2011 Annual Report.

ITEM 4. CONTROLS AND PROCEDURES

(a) Disclosure Controls and Procedures. We maintain a set of disclosure controls and procedures designed to provide reasonable assurance that information required to be disclosed in our reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. We have investments in certain unconsolidated entities that we do not control or manage. Because we do not control or manage these entities, our disclosure controls and procedures with respect to these entities are necessarily more limited than those we maintain with respect to our consolidated subsidiaries.

The Company’s management, with the participation of the Company’s Deputy Chairman, President and Chief Executive Officer and its Principal Accounting and Financial Officer (the “reviewing officers”), has evaluated the effectiveness of the Company’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on this evaluation, the reviewing officers have concluded that, as of the end of the period, the Company’s disclosure controls and procedures are effective, at the reasonable assurance level, in recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed by the Company in reports that it files or furnishes under the Exchange Act and are effective, at the reasonable assurance level, in ensuring that information required to be disclosed by the Company in the reports that it files or furnishes under the Exchange Act is accumulated and communicated to the Company’s management, including the reviewing officers, as appropriate to allow timely decisions regarding required disclosure.

(b) Changes in Internal Control Over Financial Reporting. There have not been any changes in our internal control over financial reporting (identified in connection with the evaluation required by paragraph (d) in Rules 13a-15 and 15d-15 under the Exchange Act) during the most recently completed quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II OTHER INFORMATION

Item 1. Legal Proceedings

Nabors and its subsidiaries are defendants or otherwise involved in a number of lawsuits in the ordinary course of business. We estimate the range of our liability related to pending litigation when we believe the amount and range of loss can reasonably be estimated. We record our best estimate of a loss when the loss is considered probable. When a liability is probable and there is a range of estimated loss with no best estimate in the range, we record the minimum estimated liability related to the lawsuits or claims. As additional information becomes available, we assess the potential liability related to our pending litigation and claims and revise our estimates. Due to uncertainties related to the resolution of lawsuits and claims, the ultimate outcome may differ from our estimates. In the opinion of management and based on liability accruals provided, our ultimate exposure with respect to these pending lawsuits and claims is not expected to have a material adverse effect on our consolidated financial position or cash flows, although they could have a material adverse effect on our results of operations for a particular reporting period.

On March 9, 2012, Nabors Global Holdings II Limited (“NGH2L”) signed a contract with ERG Resources, LLC (“ERG”) relating to the sale of all of the Class A shares of NGH2L’s wholly owned subsidiary, Ramshorn International Limited, an oil and gas exploration company. When ERG failed to meet its closing obligations, NGH2L terminated the transaction on March 19, 2012 and, as contemplated in the agreement, retained ERG’s $3 million escrow deposit. ERG filed suit the following day in the 61^st Judicial District Court of Harris County, Texas, in a case styledERG Resources, LLC v. Nabors Global Holdings II Limited, Ramshorn International Limited,andParex Resources, Inc.;Cause No. 2012-16446, seeking injunctive relief to halt any sale of the shares to a third party, specifically naming as defendant Parex Resources, Inc. (“Parex”). The lawsuit also seeks monetary damages of up to $100 million based on an alleged breach of contract by NGH2L and tortious interference with contractual relations by Parex. Nabors successfully defeated ERG’s effort to obtain a temporary restraining order from the Texas court on March 20, 2012. On March 23, 2012, ERG filed and obtained anex parte stay from the Supreme Court of Bermuda (Commercial Court), in a case styled asERG Resources LLC v. Nabors Global Holdings II Limited, Case No. 2012: No. 110. Nabors challenged the stay and, following a series of oral hearings on the matter, the Bermuda court discharged the stay by a ruling dated April 5, 2012. Nabors completed the sale of Ramshorn’s Class A shares to a Parex affiliate on April 12, 2012, which mooted ERG’s application for a temporary injunction that was scheduled for hearing by the Texas court on April 13, 2012. ERG retains its causes of action for monetary damages, but Nabors believes the claims are foreclosed by the terms of the agreement and are without factual or legal merit. While Nabors intends to vigorously defend the lawsuit, the ultimate outcome of the lawsuit cannot be determined at this time.
