References in this report to “Nabors Delaware” mean Nabors Industries, Inc., a wholly owned subsidiary of Nabors.

With operations in approximately 25 countries, Nabors is a global provider of drilling and drilling-related services for land-based and offshore oil and natural gas wells, with a fleet of rigs and drilling-related equipment which, as of September 30, 2018 included:

· 399 actively marketed rigs for land-based drilling operations in the United States, Canada and approximately 23 other countries throughout the world; and

Note 2 Summary of Significant Accounting Policies

Interim Financial Information

The accompanying unaudited condensed consolidated financial statements of Nabors have been prepared in conformity with generally accepted accounting principles in the United States (“U.S. GAAP”). 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 U.S. GAAP have been omitted. Therefore, these financial statements should be read together with our annual report on Form 10-K for the year ended December 31, 2017 (“2017 Annual Report”). In management’s opinion, the unaudited condensed consolidated financial statements contain all adjustments necessary to state fairly our financial position as of September 30, 2018 and the results of operations, comprehensive income (loss), cash flows and changes in equity for the periods presented herein. Interim results for the nine months ended September 30, 2018 may not be indicative of results that will be realized for the full year ending December 31, 2018.

Principles of Consolidation

Our condensed consolidated financial statements include the accounts of Nabors, as well as all majority owned and non-majority owned subsidiaries required to be consolidated under U.S. GAAP. All significant intercompany accounts and transactions are eliminated in consolidation.

In addition to the consolidation of our majority owned subsidiaries, we also consolidate variable interest entities (“VIE”) when we are determined to be the primary beneficiary of a VIE. Determination of the primary beneficiary of a VIE is based on whether an entity has (1) the power to direct activities that most significantly impact the economic performance of the VIE and (2) the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. Our determination of the primary beneficiary of a VIE considers all relationships between us and the VIE. During 2016, we entered into an agreement with Saudi Aramco, to form a new joint venture, SANAD, to own, manage and operate onshore drilling rigs in the Kingdom of Saudi Arabia. SANAD, which is equally owned by Saudi Aramco and Nabors, began operations during the fourth quarter of 2017. As we have the power to direct activities that most significantly impact SANAD’s economic performance, including operations, maintenance and certain sourcing and procurement, we have determined Nabors to be the primary beneficiary and accordingly consolidate the joint venture. See Note 3—Joint Ventures.

Revenue Recognition

We recognize revenues and costs on daywork contracts daily as the work progresses over the contract term. For certain contracts, we receive lump sum payments for the mobilization of rigs and other drilling equipment. We defer revenue related to mobilization periods and recognize the revenue over the term of the related drilling contract.

Costs incurred related to a mobilization period for which a contract is secured are deferred and recognized over the term of the related drilling contract. Costs incurred to relocate rigs and other drilling equipment to areas in which a contract has not been secured are expensed as incurred. We defer recognition of revenue on amounts received from customers for prepayment of services until those services are provided.

We recognize revenue for top drives and other capital equipment we manufacture upon transfer of control, which generally occurs when the product has been shipped to the customer.

We recognize, as operating revenue, proceeds from business interruption insurance claims in the period that the claim is realizable. Proceeds from casualty insurance settlements in excess of the carrying value of damaged assets are recognized in other, net in our condensed consolidated statement of income (loss) in the period that the applicable proof of loss documentation is received. Proceeds from casualty insurance settlements that are expected to be less than the carrying value of damaged assets are recognized at the time the loss is incurred and recorded in other, net in our condensed consolidated statement of income (loss).

We recognize reimbursements received for out of pocket expenses incurred as revenues and account for out of pocket expenses as direct costs.

Inventory, net

Inventory is stated at the lower of cost or net realizable value. Cost is determined using the first-in, first-out or weighted-average cost methods and includes the cost of materials, labor and manufacturing overhead. Inventory included the following:

Raw materials	$	124,230	$	124,635

Property, Plant and Equipment

We review our assets for impairment when events or changes in circumstances indicate that their carrying amounts may not be recoverable. If the estimated undiscounted future cash flows are not sufficient to support the asset’s recorded value, an impairment charge is recognized to the extent the carrying amount of the long-lived asset exceeds its estimated fair value. Management considers a number of factors such as estimated future cash flows from the assets, appraisals and current market value analysis in determining fair value. The determination of future cash flows requires the estimation of utilization, dayrates, operating margins, sustaining capital and remaining economic life. Such estimates can change based on market conditions, technological advances in the industry or changes in regulations governing the industry. Significant and unanticipated changes to the assumptions could result in future impairments. A significantly prolonged period of lower oil and natural gas prices could continue to adversely affect the demand for and prices of our services, which could result in future impairment charges. As the determination of whether impairment charges should be recorded on our long-lived assets is subject to significant management judgment, and an impairment of these assets could result in a material charge on our consolidated statements of income (loss), management believes that accounting estimates related to impairment of long-lived assets are critical.

For an asset classified as held for sale, we consider the asset impaired when its carrying amount exceeds fair value less its cost to sell. Fair value is determined in the same manner as a long lived asset that is held and used.

9

In June 2018, we sold three of our offshore jackup rigs for approximately $61.4 million in cash and publicly traded shares with a value of $21.8 million at closing. The sale resulted in a loss of $63.7 million, which has been recognized in other, net on our condensed consolidated statement of income (loss) for the nine months ended September 30, 2018. This long-lived asset group was reported under our International segment. The sale of these offshore jackup rigs did not constitute a triggering event for the remainder of our rig fleet.

Goodwill

We review goodwill for impairment annually during the second quarter of each fiscal year or more frequently if events or changes in circumstances indicate that the carrying amount of such goodwill and intangible assets may exceed their fair value. We initially assess goodwill for impairment based on qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of one of our reporting units is greater than its carrying amount. If the carrying amount exceeds the fair value, an impairment charge will be recognized in an amount equal to the excess; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit.

Our estimated fair values of our reporting units incorporate judgment and the use of estimates by management. The fair values calculated in these impairment tests were determined using discounted cash flow models involving assumptions based on our utilization of rigs or other oil and gas service equipment, revenues and earnings from affiliates, as well as direct costs, general and administrative costs, depreciation, applicable income taxes, capital expenditures and working capital requirements. Our discounted cash flow projections for each reporting unit were based on financial forecasts. The future cash flows were discounted to present value using discount rates determined to be appropriate for each reporting unit. Terminal values for each reporting unit were calculated using a Gordon Growth methodology with a long term growth rate of 3%.

Another factor in determining whether impairment has occurred is the relationship between our market capitalization and our book value. As part of our annual review, we compared the sum of our reporting units’ estimated fair value, which included the estimated fair value of non-operating assets and liabilities, less debt, to our market capitalization and assessed the reasonableness of our estimated fair value. Any of the above mentioned factors may cause us to re-evaluate goodwill during any quarter throughout the year.

Based on our annual review during the second quarter of 2018, we did not record a goodwill impairment. However, a significantly prolonged period of lower oil prices could adversely affect demand for and prices of our services. Additionally, our ability to commercialize our rotary steerable drilling technology tools could impact the discounted cash flow models. These factors could result in future impairment charges, particularly in our U.S. Drilling and Rig Services segments.

Recently Adopted Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, Revenue from Contracts with Customers, relating to the revenue recognition from contracts with customers that creates a common revenue standard for U.S. GAAP and IFRS. The core principle requires the recognition of revenue to represent the transfer of promised goods or services to customers in an amount that reflects the consideration, including costs incurred, to which the entity expects to be entitled in exchange for those goods or services. The standard also requires significantly expanded disclosures containing qualitative and quantitative information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In July 2015, the FASB approved a one year deferral of this standard, with a new effective date for fiscal years beginning after December 15, 2017. Throughout 2017 we, along with our third party consultants, identified and reviewed our revenue streams, identified a subset of contracts to represent these revenue streams and performed a detailed analysis of such contracts. We adopted this guidance under the modified retrospective approach as of January 1, 2018. The adoption of this standard did not have a material impact on our consolidated financial statements. See Note 12—Revenue Recognition.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments—Overall, relating to the recognition and measurement of financial assets and liabilities. This standard enhances the reporting model for financial instruments, which includes amendments to address aspects of recognition, measurement, presentation and disclosure. This new standard became effective for us on January 1, 2018. Upon adoption, we recorded an adjustment to retained earnings of $9.1 million to eliminate the net unrealized gain balance in accumulated other comprehensive income (loss) related to the

10

marketable securities. If we do have a material amount of investments in marketable securities in the future, we expect that the impact to our consolidated statements of income (loss) and other comprehensive income (loss) from this update could be material. Furthermore, depending on trends in the stock market, we may see increased volatility in our consolidated statements of income (loss) and other comprehensive income (loss).

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows, to reduce the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This guidance is effective for public companies for fiscal years beginning after December 15, 2017. Early application is permitted. The adoption of this standard did not have a material impact on our consolidated financial statements.

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes, which simplifies the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. We adopted this standard during the first quarter of 2018 using the modified retrospective method, through a cumulative-effect adjustment directly to retained earnings. Upon adoption, we reduced deferred tax assets by approximately $34.1 million and recognized an offsetting decrease to retained earnings.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash, to provide guidance on the classification of restricted cash in the statement of cash flows. This guidance is effective for public companies for fiscal years beginning after December 15, 2017. The amendments in the ASU should be adopted on a retrospective basis. The adoption of this standard did not have a material impact on our consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business, which clarifies the definition of a business and provides further guidance for evaluating whether a transaction will be accounted for as an acquisition of an asset or a business. The standard provides a test to determine whether a set of assets and activities acquired is a business. When substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets, the set is not a business. Under the updated guidance, an acquisition of a single property will likely be treated as an asset acquisition as opposed to a business combination and associated transaction costs will be capitalized rather than expensed as incurred. Additionally, assets acquired, liabilities assumed, and any noncontrolling interest will be measured at their relative fair values. The adoption of this standard did not have a material impact on our consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation, to reduce diversity in practice and provide clarity regarding existing guidance in ASC 718, “Stock Compensation”. The standard provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions and classification of the awards are the same immediately before and after the modification. This guidance is effective for public companies for fiscal years beginning after December 15, 2017. The adoption of this standard did not have a material impact on our consolidated financial statements.

Recent Accounting Pronouncements Not Yet Adopted

In February 2016, the FASB issued ASU No. 2016-02, Leases, relating to leases to increase transparency and comparability among companies. This standard requires that all leases with an initial term greater than one year be recorded on the balance sheet as an asset and a lease liability. Additionally, this standard will require disclosures designed to give financial statement users information on the amount, timing, and uncertainty of cash flows arising from leases. A modified retrospective approach is currently required for the adoption of this guidance, which is effective for our reporting period beginning January 1, 2019. Early adoption is permitted. We are currently evaluating the impact this will have on our consolidated financial statements.

In February 2018, the FASB issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017. In addition, the standard requires certain disclosures regarding stranded tax effects. This guidance is effective for public companies for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We are currently evaluating the impact this will have on our consolidated financial statements.

Note 3 Joint Ventures

During 2016, we entered into an agreement with Saudi Aramco to form SANAD, a new joint venture, to own, manage and operate onshore drilling rigs in the Kingdom of Saudi Arabia. SANAD, which is equally owned by Saudi Aramco and Nabors, began operations during the fourth quarter of 2017.

During 2017, Nabors and Saudi Aramco each contributed $20 million in cash for the purpose of capitalizing the joint venture upon formation. In addition, since inception Nabors and Saudi Aramco have each contributed a combination of drilling rigs, drilling rig equipment and other assets, including cash, each with a value of approximately $394 million to the joint venture. During September 2018, we contributed drilling rigs and equipment with a value of approximately $190 million. On October 4, 2018, we received Saudi Aramco’s matching contribution of drilling rigs and other assets, including cash. The contributions were received in exchange for redeemable ownership interests which accrue interest annually, have a twenty-five year maturity and are required to be converted to authorized capital should certain events occur, including the accumulation of specified losses. In the accompanying consolidated balance sheet, Nabors has reported Saudi Aramco’s share of authorized capital as a component of noncontrolling interest in equity and Saudi Aramco’s share of the redeemable ownership interests as redeemable noncontrolling interest in subsidiary, classified as mezzanine equity. The accrued interest on the redeemable ownership interest is a non-cash financing activity and is reported as an increase in the redeemable noncontrolling interest in subsidiary line in our condensed consolidated balance sheet.

The condensed balance sheet of SANAD, as included in our consolidated balance sheet, is presented below.

The assets of SANAD cannot be used by Nabors for general corporate purposes. Additionally, creditors of SANAD do not have recourse to other assets of Nabors.

Note 4 Fair Value Measurements

Fair value is the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date (exit price). We utilize market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market‑corroborated, or generally unobservable. We primarily apply the market approach for recurring fair value measurements and endeavor to utilize the best information available. Accordingly, we employ valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The use of unobservable inputs is intended to allow for fair value determinations in situations where there is little, if any, market activity for the asset or liability at the measurement date. We are able to classify fair value balances utilizing a fair value hierarchy based on the observability of those inputs. Under the fair value hierarchy:

· Level 1 measurements include unadjusted quoted market prices for identical assets or liabilities in an active market;

· Level 2 measurements include quoted market prices for identical assets or liabilities in an active market that have been adjusted for items such as effects of restrictions for transferability and those that are not

12

quoted but are observable through corroboration with observable market data, including quoted market prices for similar assets; and

· Level 3 measurements include those that are unobservable and of a subjective nature.

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. There were no transfers of our financial assets between Level 1 and Level 2 measures during the nine months ended September 30, 2018. 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

We applied fair value measurements to our nonfinancial assets and liabilities measured on a nonrecurring basis, which consist of measurements primarily to assets held for sale, goodwill, equity method investments, intangible assets and other long-lived assets, assets acquired and liabilities assumed in a business combination and our pipeline contractual commitment. Based upon our review of the fair value hierarchy, the inputs used in these fair value measurements were considered Level 3 inputs.

Fair Value of Financial Instruments

We estimate the fair value of our financial instruments in accordance with U.S. GAAP. The fair value of our long-term debt, revolving credit facility and commercial paper is estimated based on quoted market prices or prices quoted from third-party financial institutions. The fair value of our debt instruments is determined using Level 2 measurements. The carrying and fair values of these liabilities were as follows:

During the nine months ended September 30, 2018, we repaid the $460.8 million aggregate principal amount outstanding on our 6.15% senior notes due February 2018 for approximately $475.0 million in cash, reflecting principal and approximately $14.2 million of accrued and unpaid interest. Additionally, we redeemed the remaining $303.5 million aggregate principal amount of our 9.25% senior notes due January 2019 for approximately $327.2 million, reflecting principal, accrued and unpaid interest. In connection with the repurchase, we recognized a loss of approximately $10.5 million, which represents the premiums paid in connection with these repurchases or redemptions and is included in other, net in our condensed consolidated statement of income (loss) for the nine months ended September 30, 2018.

5.75% Senior Notes Due February 2025

In January 2018, Nabors Industries, Inc. (“Nabors Delaware”), a wholly owned subsidiary of Nabors, issued $800 million in aggregate principal amount of 5.75% senior unsecured notes due February 1, 2025, which are fully and unconditionally guaranteed by Nabors. The notes subsequently were exchanged for notes registered under the Securities Act pursuant to an exchange offer that took place in August 2018. The notes pay interest semi-annually on February 1 and August 1, beginning on August 1, 2018, and will mature on February 1, 2025.

The notes rank equal in right of payment to all of Nabors Delaware’s existing and future unsubordinated indebtedness, and senior in right of payment to all of Nabors Delaware’s existing and future senior subordinated and subordinated indebtedness. Our guarantee of the notes is unsecured and an unsubordinated obligation and ranks equal in right of payments to all of our unsecured and unsubordinated indebtedness from time to time outstanding. In the event of a change of control triggering event, as defined in the indenture, the holders of the notes may require Nabors Delaware to purchase all or a portion of the notes at a purchase price equal to 101% of their principal amount, plus accrued and unpaid interest, if any. The notes are redeemable in whole or in part at any time at the option of Nabors Delaware at a redemption price, plus accrued and unpaid interest, as specified in the indenture. Nabors Delaware used a portion of the proceeds to repay the amount outstanding on the 6.15% senior notes due February 2018. The remaining proceeds not used for such purposes were allocated for general corporate purposes, including to repay amounts outstanding under the commercial paper program and to repurchase or repay other indebtedness.

0.75% Senior Exchangeable Notes Due January 2024

In January 2017, Nabors Delaware issued $575 million in aggregate principal amount of 0.75% exchangeable senior unsecured notes due 2024, which are fully and unconditionally guaranteed by Nabors. The notes bear interest at a rate of 0.75% per year payable semiannually on January 15 and July 15 of each year, beginning on July 15, 2017. The exchangeable notes are bifurcated for accounting purposes into debt and equity components of $411.2 million and $163.8 million, respectively, based on the relative fair value. Debt issuance costs of $9.6 million and equity issuance costs of $3.9 million were capitalized in connection with the issuance of these notes in long-term debt and netted against the proceeds allocated to the equity component, respectively, in our condensed consolidated balance sheet. The debt issuance costs are being amortized through January 2024.

The exchangeable notes are exchangeable, under certain conditions, at an initial exchange rate of 39.75 common shares of Nabors per $1,000 principal amount of exchangeable notes (equivalent to an initial exchange price of approximately $25.16 per common share). Upon any exchange, Nabors Delaware will settle its exchange obligation in cash, common shares of Nabors, or a combination of cash and common shares, at our election.

In connection with the pricing of the notes, we entered into privately negotiated capped call transactions which are expected to reduce potential dilution to common shares and/or offset potential cash payments required to be made in excess of the principal amount upon any exchange of notes. Such reduction and/or offset is subject to a cap representing a price per share of $31.45, an approximately 75.0% premium over our share price of $17.97 as of the date of the transaction. The capped call meets the definition of a derivative under ASC 815, Derivatives and Hedging, as it has an underlying (the Company’s share price), a notional amount (the number of underlying shares to be purchased per option), an initial net investment less (by more than a nominal amount) than the amount that would have to be paid to own the underlying and provides for a default net share settlement (but could also be settled in cash at the election of the Company). However, the capped call meets the derivative scope exception under ASC 815 for instruments indexed to the Company’s own stock and classified in shareholders’ equity and therefore was initially recorded in equity. Until such time as the Company elects a settlement method for the exchangeable notes, the capped call transaction will continue to be accounted for as equity. At conversion, if the Company elects to partially settle the notes in cash in excess of the principal amount, or fully in cash, the capped call will be subject to mark to market through earnings as a derivative until such settlement is paid.

The net proceeds from the offering of the exchangeable notes were used to prepay the remaining balance of our unsecured term loan originally scheduled to mature in 2020, as well as to pay the cost of the capped call transactions. The remaining net proceeds from the offering were allocated for general corporate purposes, including to repurchase or repay other indebtedness.

Commercial Paper Program

In February 2018, we utilized a portion of the proceeds received in connection with the 5.75% senior notes offering to repay the outstanding balance on the commercial paper program. In March 2018, the program was terminated.

2018 Revolving Credit Facility

On October 11, 2018, Nabors Delaware, Nabors Drilling Canada Limited, an Alberta corporation (“Nabors Canada”), Nabors and certain other of Nabors’ wholly owned subsidiaries entered into a new five-year unsecured revolving facility with the lenders and issuing banks party thereto and Citibank, N.A., as administrative agent (the “2018 Revolving Credit Facility”). The 2018 Revolving Credit Facility has a borrowing capacity of $1.267 billion and is fully and unconditionally guaranteed by Nabors and certain of its wholly owned subsidiaries. The 2018 Revolving Credit Facility matures at the earlier of (a) October 11, 2023 and (b) July 19, 2022, if any of Nabors Delaware’s existing 5.5% senior notes due January 2023 remain outstanding as of such date. Certain lenders have committed to provide Nabors Delaware an aggregate principal amount of $1.227 billion under the 2018 Revolving Credit Facility, which may be drawn in U.S. dollars, and HSBC Bank Canada has committed to provide Nabors Canada an aggregate principal amount of $40 million in U.S. dollar equivalent, which can be drawn upon in either U.S. or Canadian dollars. The 2018 Revolving Credit Facility contains certain affirmative and negative covenants, including a financial covenant requiring Nabors to maintain a debt to capitalization ratio not in excess of 0.60:1. Additionally, during any period in which Nabors Delaware fails to maintain an investment grade rating from at least two ratings agencies, the guarantors under the facility and their respective subsidiaries will be required to maintain an asset to debt coverage ratio (as defined in the 2018

16

Revolving Credit Facility) of at least 2.50:1. As of the date of this report, we had no borrowings outstanding under our 2018 Revolving Credit Facility.

2012 Revolving Credit Facility

In connection with the 2018 Revolving Credit Facility, on October 11, 2018, Nabors Delaware entered into Amendment No. 3 to its existing credit agreement dated November 29, 2012 (as amended, including such amendment, the “2012 Revolving Credit Facility”), among itself, Nabors, Nabors Canada, HSBC Bank Canada, the other lenders party thereto, Citibank, N.A., and Wilmington Trust, National Association, as successor administrative agent (the “Amendment”). The Amendment, among other things, provides for Citibank, N.A.’s resignation as administrative agent and the appointment of Wilmington Trust, National Association as administrative agent, reduces the overall commitments available to $666.25 million and provides for certain lenders to exit the facility in order to become lenders under the 2018 Revolving Credit Facility. Availability under the 2012 Revolving Credit Facility is subject to a covenant not to exceed a net debt to capital ratio of 0.60:1. As of September 30, 2018, we had $215.0 million outstanding under the 2012 Revolving Credit Facility. The weighted average interest rate on borrowings during the nine month period ended September 30, 2018 was 3.32%. The 2012 Revolving Credit Facility matures on July 14, 2020.

As of the date of this report, we were in compliance with all covenants under the 2018 Revolving Credit Facility and 2012 Revolving Credit Facility. If we fail to perform our obligations under the covenants, the revolving credit commitment could be terminated, and any outstanding borrowings under the facility could be declared immediately due and payable.

Term Loan Facility

On September 29, 2015, Nabors Delaware entered into a new five-year unsecured term loan facility for $325.0 million, which was fully and unconditionally guaranteed by us. The term loan facility contained a mandatory prepayment of $162.5 million due in September 2018, which was repaid in December 2016 utilizing a portion of the proceeds received in connection with the 5.50% senior notes due January 2023 offering. In January 2017, we repaid the remaining $162.5 million term loan utilizing a portion of the proceeds received in connection with the 0.75% senior exchangeable notes and the facility was terminated.

Note 6 Shareholders’ Equity

Common shares

In May 2018, we issued 35,000,000 shares of common stock at a price to the public of $7.75 per share. In connection with this offering, in June 2018 the underwriters exercised in full their option to purchase 5,250,000 additional common shares. Nabors received aggregate net proceeds of approximately $301.8 million after deducting underwriting discounts, commissions and offering expenses.

During the year ended December 31, 2017, we repurchased 3.1 million of our common shares in the open market for $18.1 million, all of which are held by our subsidiaries, and which are accounted for as treasury shares.

On February 23, 2018, a cash dividend of $0.06 per share was declared for shareholders of record on March 13, 2018. The dividend was paid on April 3, 2018 in the amount of $19.1 million. On April 20, 2018, a cash dividend of $0.06 per common share was declared for shareholders of record on June 12, 2018. The dividend was paid on July 3, 2018 in the amount of $21.5 million.  On July 27, 2018, a cash dividend of $0.06 per common share was declared for shareholders of record on September 11, 2018. The dividend was paid on October 2, 2018 in the amount of $21.4 million. These dividends were charged to retained earnings in our condensed consolidated statements of changes in equity for the nine months ended September 30, 2018.

On November 6, 2018, our Board of Directors declared a cash dividend of $0.06 per common share, which will be paid on January 3, 2019 to shareholders of record at the close of business on December 13, 2018.

Convertible Preferred Shares

In May 2018, we issued 5,750,000 shares (including the underwriters option for 750,000 shares) of 6% Series A Mandatory Convertible Preferred Stock (the “mandatory convertible preferred shares”), par value $.001 per share, with a liquidation preference of $50 per share. Nabors received aggregate net proceeds of approximately $278.4 million after deducting underwriting discounts, commissions and offering expenses.

The dividends on the mandatory convertible preferred shares will be payable on a cumulative basis. At issuance, each share of the mandatory convertible preferred shares was automatically convertible into between 5.3763 and 6.4516 of our common shares based on the average share price over a period of twenty consecutive trading days ending prior to May 1, 2021, subject to anti-dilution adjustments. In connection with the dividend on our common shares paid on October 2, 2018, the conversion rate for each share of the mandatory convertible preferred shares was adjusted to between 5.4735 and 6.5683 of our common shares.

On June 6, 2018, a cash dividend of $0.64 per mandatory convertible preferred share was declared for shareholders of record on July 13, 2018. The dividend was paid on August 1, 2018 in the amount of $3.7 million. On July 27, 2018, a cash dividend of $0.75 per mandatory convertible preferred share was declared for shareholders of record on October 15, 2018. The dividend was paid on November 1, 2018 in the amount of $4.3 million. These dividends were charged to retained earnings in our condensed consolidated statements of changes in equity for the nine months ended September 30, 2018.

On November 6, 2018, our Board of Directors declared a cash dividend of $0.75 per mandatory convertible preferred share, which will be paid on February 1, 2019 to shareholders of record at the close of business on January 15, 2019 in the amount of $4.3 million.

Note 7 Commitments and Contingencies

Contingencies

Income Tax

We operate in a number of countries throughout the world and our tax returns filed in those jurisdictions are subject to review and examination by tax authorities within those jurisdictions. We do not recognize the benefit of income tax positions we believe are more likely than not to be disallowed upon challenge by a tax authority. If any tax authority successfully challenges our operational structure, intercompany pricing policies or the taxable presence of our subsidiaries in certain countries, if the terms of certain income tax treaties are interpreted in a manner that is adverse to our structure, or if we lose a material tax dispute in any country, our effective tax rate on our worldwide earnings could change substantially.

We have received an assessment from a tax authority in Latin America in connection with a 2007 income tax return. The assessment relates to the denial of depreciation expense deductions related to drilling rigs. Similar deductions were taken for tax year 2009. Although Nabors and its tax advisors believe these deductions are appropriate and intend to continue to defend our position, the contingency has been partially reserved. If we ultimately do not prevail, we estimate that we would be required to recognize additional tax expense for the entire contingency in the range of $3 million to $8 million.  

In certain jurisdictions we have recognized deferred tax assets and liabilities. Judgment and assumptions are required in determining whether deferred tax assets will be fully or partially utilized. When we estimate that all or some portion of certain deferred tax assets such as net operating loss carryforwards will not be utilized, we establish a valuation allowance for the amount we determine to be more likely than not unrealizable. We continually evaluate strategies that could allow for future utilization of our deferred tax assets. Any change in the ability to utilize such deferred tax assets will be accounted for in the period of the event affecting the valuation allowance. If facts and circumstances cause us to change our expectations regarding future tax consequences, the resulting adjustments could have a material effect on our financial results or cash flow. The area at greatest risk is our Canada Drilling operations. At this time, we consider it more likely than not that we will have sufficient taxable income in the future that will allow us to realize the deferred tax assets that we have recognized. However, it is possible that some of our recognized deferred tax assets, relating to net operating loss carryforwards, could expire unused or could carryforward indefinitely without

18

utilization. Therefore, unless we are able to generate sufficient taxable income from our component operations, a substantial valuation allowance to reduce our deferred tax assets may be required, which would materially increase our tax expense in the period the allowance is recognized and materially adversely affect our results of operations and statement of financial condition.

Self-Insurance

We estimate the level of our liability related to insurance and record reserves for these amounts in our condensed 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 and are actuarially supported. 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.

We self-insure for certain losses relating to workers’ compensation, employers’ liability, general liability, automobile liability and property damage. Some of our workers’ compensation, employers’ liability and marine employers’ liability claims are subject to a $3.0 million per-occurrence deductible; additionally, some of our automobile liability claims are subject to a $2.5 million deductible. General liability claims remain subject to a $5.0 million per-occurrence deductible. Our policies were renewed effective April 1, 2018 and remain subject to these same deductibles.

In addition, we are subject to a $5.0 million deductible for land rigs and for offshore rigs. This applies to all kinds of risks of physical damage except for named windstorms in the U.S. Gulf of Mexico for which we are self-insured.

Effective May 22, 2018, our platform rig, MODS-400, is subject to a limit of $200.0 million with a $5.0 million deductible for named windstorm damage in the U.S. Gulf of Mexico.

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.

In March 2011, the Court of Ouargla entered a judgment of approximately $23.9 million (at September 30, 2018 exchange rates) 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. 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 upheld the lower court’s ruling, and we appealed the matter to the Supreme Court. On September 25, 2014, the Supreme Court overturned the verdict against us, and the case was reheard by the Ouargla Court of Appeals on March 22, 2015 in light of the Supreme Court’s opinion. On March 29, 2015, the Ouargla Court of Appeals reinstated the initial judgment against us. We have appealed this decision again to the Supreme Court. While our payments were consistent with our historical operations in the country, and, we believe, those of other multinational corporations there, as well as interpretations of the law by the Central Bank of Algeria, the ultimate resolution of this matter could result in a loss of up to $15.9 million in excess of amounts accrued.

19

On September 29, 2017, Nabors and Nabors Maple Acquisition Ltd. were sued, along with Tesco Corporation (“Tesco”) and its Board of Directors, in a putative shareholder class action filed in the United States District Court for the Southern District of Texas, Houston Division. The plaintiff alleges that the September 18, 2017 Preliminary Proxy Statement filed by Tesco with the United States Securities and Exchange Commission omitted material information with respect to the proposed transaction between Tesco and Nabors announced on August 14, 2017. The plaintiff claims that the omissions rendered the Proxy Statement false and misleading, constituting a violation of Sections 14(a) and 20(a) of the Securities Exchange Act of 1934, and alleges liability by Nabors as a control person of Tesco. The court consolidated several matters and entered a lead plaintiff appointment order. The plaintiff filed their amended complaint, adding Nabors Industries, Ltd. as a party. Nabors has filed its motion to dismiss and will vehemently defend itself against the allegations.

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 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
	2018		2019	2020	Thereafter	Total
	(In thousands)
Financial standby letters of credit and other financial surety instruments	$	27,518	149,692	40	—	$	177,250

Note 8 Earnings (Losses) Per Share

ASC 260, Earnings per Share, requires companies to treat unvested share-based payment awards that have nonforfeitable rights to dividends or dividend equivalents as a separate class of securities in calculating earnings (losses) per share. We have granted and expect to continue to grant to employees restricted stock grants that contain nonforfeitable rights to dividends. Such grants are considered participating securities under ASC 260. As such, we are required to include these grants in the calculation of our basic earnings (losses) per share and calculate basic earnings (losses) per share using the two-class method. The two-class method of computing earnings per share is an earnings allocation formula that determines earnings per share for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. The participating security holders are not contractually obligated to share in losses. Therefore, losses are not allocated to the participating security holders.

Basic earnings (losses) per share is computed utilizing the two-class method and is calculated based on the weighted-average number of common shares outstanding during the periods presented.

Diluted earnings (losses) per share is computed using the weighted-average number of common and common equivalent shares outstanding during the periods utilizing the two-class method for stock options and unvested restricted stock. Shares issuable upon exchange of the $575 million 0.75% exchangeable notes are not included in the calculation of diluted earnings (losses) per share unless the exchange value of the notes exceeds their principal amount at the end of the relevant reporting period, in which case the notes will be accounted for as if the number of common shares that would be necessary to settle the excess are issued. Such shares are only included in the calculation of the weighted-average number of shares outstanding in our diluted earnings (losses) per share calculation, when the price of our shares exceeds $25.16 on the last trading day of the quarter, which did not occur during the nine months ended September 30, 2018.

For all periods presented, the computation of diluted earnings (losses) per share excludes outstanding stock options 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. For periods in which we experience a net loss from continuing operations, all potential common shares have been excluded from the calculation of weighted-average

21

shares outstanding, because their inclusion would be anti-dilutive. The average number of options that were excluded from diluted earnings (losses) per share that would potentially dilute earnings per share in the future were as follows:

		Three Months Ended				Nine Months Ended
		September 30,				September 30,
		2018		2017		2018		2017
	(In thousands)
Potentially dilutive securities excluded as anti-dilutive			4,354		4,484		4,488		4,534

In any period during which the average market price of Nabors’ common shares exceeds the exercise prices of these stock options, such stock options will be included in our diluted earnings (losses) per share computation using the if-converted method of accounting. Restricted stock is 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 participating securities.

Additionally, we excluded 37.8 million common shares from the computation of diluted shares issuable upon the conversion of mandatory convertible preferred shares, because their effect would be anti-dilutive under the if-converted method.

Note 10 Assets Held for Sale and Discontinued Operations

Assets Held for Sale

Assets held for sale as of September 30, 2018 and December 31, 2017 was $20.3 million and $37.1 million, respectively. These assets consisted primarily of our oil and gas holdings which are mainly in the Horn River basin in western Canada of $10.1 million and $25.9 million, respectively, as of the periods noted above and the operating results have been reflected in discontinued operations. The remainder represents assets that meet the criteria to be classified as assets held for sale, but do not represent a disposal of a component of an entity or a group of components of an entity representing a strategic shift that has or will have a major effect on the entity's operations and financial results.

The carrying value of our assets held for sale represents the lower of carrying value or fair value less costs to sell. We continue to market these properties at prices that are reasonable compared to current fair value.

We have contracts with pipeline companies to pay specified fees based on committed volumes for gas transport and processing associated with these properties held for sale. At September 30, 2018, our undiscounted contractual commitments for these contracts approximated $5.8 million and we had liabilities of $5.8 million, all of which was classified as current and included in accrued liabilities. At December 31, 2017, our undiscounted contractual commitments for these contracts approximated $11.2 million and we had liabilities of $8.5 million, $6.1 million of which were classified as current and were included in accrued liabilities.

The amounts at each balance sheet date represented our best estimate of the fair value of the excess capacity of the pipeline commitments calculated using a discounted cash flow model, when considering our disposal plan, current production levels, natural gas prices and expected utilization of the pipeline over the remaining contractual term. Decreases in actual production or natural gas prices could result in future charges related to excess pipeline commitments.

Note 12 Revenue Recognition

On January 1, 2018, we adopted Topic 606, Revenue from Contracts with Customers (ASC 606). Under ASC 606, revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration we expect to receive in exchange for those goods or services. In addition, ASC 606 requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers.

We elected to adopt the standard using the modified retrospective method to all contracts that were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported under the accounting standards in effect for the prior period. There was no impact to our consolidated financial statements as a result of adopting ASC 606.

We recognize revenue when control of a good or service promised in a contract (i.e., performance obligation) is transferred to a customer. Control is obtained when a customer has the ability to direct the use of and obtain substantially all of the remaining benefits from that good or service. Contract drilling revenues are recorded over time utilizing the input method based on time elapsed. The measurement of progress considers the transfer of the service to the customer as we provide daily drilling services. We receive payment after the services have been performed by billing customers periodically (typically monthly). However, a portion of our revenues are recognized at a point-in-time as control is

26

transferred at a distinct point in time such as with the sale of our top drives and other capital equipment. Within our drilling contracts, we have identified one performance obligation in which the transaction price is allocated.

Disaggregation of revenue

In the following table, revenue is disaggregated by geographical region. The table also includes a reconciliation of the disaggregated revenue with the reportable segments:

Contract balances

We perform our obligations under a contract with a customer by transferring goods or services in exchange for consideration from the customer. We recognize a contract asset or liability when we transfer goods or services to a customer and bill an amount which differs from the revenue allocated to the related performance obligations.

The timing of revenue recognition may differ from the timing of invoicing to customers and these timing differences result in receivables, contract assets, or contract liabilities (deferred revenue) on our condensed consolidated balance sheet. In general, we receive payments from customers based on dayrates as stipulated in our contracts (i.e. operating rate, standby rate). The invoices billed to the customer are based on the varying rates applicable to the operating status on each rig. Accounts receivable are recorded when the right to consideration becomes unconditional.

Dayrate contracts also may contain fees charged to the customer for up-front rig modifications, mobilization and demobilization of equipment and personnel. These fees are associated with contract fulfillment activities, and the related revenue (subject to any constraint on estimates of variable consideration) is allocated to a single performance obligation and recognized ratably over the initial term of the contract. Mobilization fees are generally billable to the customer in the initial phase of a contract and generate contract liabilities until they are recognized as revenue. Demobilization fees are generally received at the end of the contract and generate contract assets when they are recognized as revenue prior to becoming receivables from the customer.

We receive reimbursements from our customers for the purchase of supplies, equipment, personnel services and other services provided at their request. Reimbursable revenues are variable and subject to uncertainty as the amounts received and timing thereof are dependent on factors outside of our influence. Accordingly, these revenues are constrained and not recognized until the uncertainty is resolved, which typically occurs when the related costs are incurred on behalf of the customer. We are generally considered a principal in these transactions and record the associated revenues at the gross amounts billed to the customer.

The opening and closing balances of our receivables, contract assets and current and long-term contract liabilities are as follows (in millions):

			Contract		Contract		Contract		Contract
	Contract		Assets		Assets		Liabilities		Liabilities
	Receivables		(Current)		(Long-term)		(Current)		(Long-term)
As of December 31, 2017	$	738.0	$	67.0	$	46.9	$	218.4	$	135.0
As of September 30, 2018	$	804.9	$	59.3	$	32.7	$	152.2	$	65.0

Approximately 63% of the contract liability balance at the beginning of the period is expected to be recognized as revenue during 2018, of which 49% was recognized during the nine months ended September 30, 2018, and 22% is expected to be recognized during 2019. The remaining 15% of the contract liability balance at the beginning of the period is expected to be recognized as revenue during 2020 or thereafter.

Additionally, 59% of the contract asset balance at the beginning of the period is expected to be recognized as expense during 2018, of which 47% was recognized during the nine months ended September 30, 2018, and 26% is expected to be recognized during 2019. The remaining 15% of the contract asset balance at the beginning of the period is

28

expected to be recognized as expense during 2020 or thereafter. This disclosure does not include variable consideration allocated entirely to a wholly unsatisfied performance obligation or promise to transfer a distinct good or service that forms part of a single performance obligation.

Note 14 Subsequent Events

On October 3, 2018, we purchased PetroMar Technologies, a small developer and operator of LWD downhole tools focusing on high-value formation data to facilitate completion optimization particularly in unconventional reservoirs. The tools complement our existing wellbore placement capabilities and will be included in our Drilling Solutions operating segment. Under the terms of the transaction, we paid an initial purchase price of $25.0 million. We may also be required to make future payments that are contingent upon the future financial performance of this operation.

Management Overview

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

We own and operate one of the world’s largest land-based drilling rig fleets and are a provider of offshore rigs in the United States and numerous international markets. Our business is comprised of our global land-based and offshore drilling rig operations and other rig related services and technologies, consisting of equipment manufacturing, rig instrumentation and optimization software. We also specialize in wellbore placement solutions and are a leading provider of directional drilling and MWD systems and services.

Financial Results

Comparison of the three months ended September 30, 2018 and 2017

Operating revenues for the three months ended September 30, 2018 totaled $779.4 million, representing an increase of $117.3 million, or 18%, compared to the three months ended September 30, 2017. We experienced an increase in operating revenue across all operating segments as activity has increased, which is evidenced by the 6% increase in average rigs working across the global fleet during the three months ended September 30, 2018 compared to the same period in 2017. Additionally, we benefited from incremental operating revenues of approximately $40.0 million as a result of our acquisition of Tesco, which was completed in the fourth quarter of 2017.

Net loss from continuing operations attributable to Nabors common shareholders totaled $105.0 million ($0.31 per diluted share) for the three months ended September 30, 2018 compared to a net loss from continuing operations attributable to Nabors common shareholders of $121.4 million ($0.42 per diluted share) for the three months ended September 30, 2017, or a $16.4 million improvement in the net loss. Although our segments’ adjusted operating income improved by approximately $65.1 million compared to the prior period, our net loss for the three months ended September 30, 2018 was negatively impacted by a $10.5 million loss on the redemption of our 9.25% senior notes due January 2019 as well as a $25.2 million increase in income tax expense.

General and administrative expenses for the three months ended September 30, 2018 totaled $66.8 million, representing an increase of $1.8 million, or 3%, compared to the three months ended September 30, 2017. This is reflective of a slight increase in salaries and other compensation as well as increases in headcount as a result of increased activity, including entry into new markets from the Company’s acquisition of Tesco in the fourth quarter of 2017.

Research and engineering expenses for the three months ended September 30, 2018 totaled $14.5 million, representing an increase of $1.5 million, or 12%, compared to the three months ended September 30, 2017. The increase is a result of increased efforts over a number of strategic research and engineering projects as the market rebalanced and activity increased.

Depreciation and amortization expense for the three months ended September 30, 2018 was $208.5 million, representing a decrease of $8.6 million, or 4%, compared to the three months ended September 30, 2017. The slight decrease was primarily due to the absence of depreciation expense associated with the jackup rigs sold during the second quarter of 2018, partially offset by an increase in depreciation expense due to the increased number of rigs working during the period as well as incremental depreciation associated with the acquisition of Tesco.

Segment Results of Operations

Our business consists of five reportable segments: U.S. Drilling, Canada Drilling, International Drilling, Drilling Solutions and Rig Technologies.

Management evaluates the performance of our reportable segments using adjusted operating income (loss), which is our segment performance measure, because it believes that this financial measure reflects our ongoing profitability and performance. In addition, securities analysts and investors use this measure as one of the metrics on which they analyze our performance. Adjusted operating income (loss) represents income (loss) from continuing operations before income taxes, interest expense, earnings (losses) from unconsolidated affiliates, investment income (loss) and other, net. A

44

reconciliation of adjusted operating income to net income (loss) from continuing operations before income taxes can be found in Note 11—Segment Information.

The following tables set forth certain information with respect to our reportable segments and rig activity:

		Three Months Ended

(1) Represents a measure of the average number of rigs operating during a given period. For example, one rig operating 45 days during a quarter represents approximately 0.5 average rigs working for the quarter. On an annual period, one rig operating 182.5 days represents approximately 0.5 average rigs working for the year.

U.S. Drilling

Operating results increased during the three months ended September 30, 2018 compared to the corresponding 2017 period primarily due to an increase in dayrates as market prices have continued to improve, which resulted in approximately $54.3 million of the increase in adjusted operating income. Additionally, we have experienced an increase in activity as reflected by a 4% increase in the average number of rigs working which represented approximately $2.5 million of the increase in adjusted operating income. Included in this amount are incremental operating results from the contribution of full operating dayrate for one of our new MODS-400 rigs in the Gulf of Mexico.

Canada Drilling

Operating results improved during the three months ended September 30, 2018 compared to the corresponding 2017 period primarily due to an increase in activity as reflected by a 33% increase in the average number of rigs working. Additionally, the increase in operating results was partially attributed to the mix of higher margin active rigs working as well as a slight increase in dayrates during the three months ended September 30, 2018.

International Drilling

Operating revenue as well as activity remained relatively flat during the three months ended September 30, 2018 compared to the corresponding 2017 period. Operating results for the period were unfavorably impacted by the expiration of higher margin contracts, which were partially offset by new rig awards in lower margin regions in combination with dayrate reduction. Further contributing to the decline in operating results was decreased activity resulting from the sale of three jackup rigs and rig recertification.

45

Drilling Solutions

Operating results increased during the three months ended September 30, 2018 compared to the corresponding 2017 period primarily due to the increase in drilling activity in the U.S. and in the demand for our products and services, including Tubular Services and Performance Tools. This segment benefited from incremental operating revenues of approximately $19.9 million related to the addition of our Tubular Services product lines as a result of the acquisition of Tesco.

Rig Technologies

Operating revenues increased during the three months ended September 30, 2018 compared to the corresponding 2017 period primarily due to approximately $18.8 million in incremental revenue as a result of the acquisition of Tesco during the fourth quarter of 2017.

Other Financial Information

Interest expense

Interest expense for the three months ended September 30, 2018 was $51.4 million, representing a decrease of $3.2 million, or 6%, compared to the three months ended September 30, 2017. The decrease was primarily due to a reduction in interest expense due to the repayment of the 6.15% senior notes due February 2018 and 9.25% senior notes due January 2019. This was partially offset by the additional interest expense related to the January 2018 issuance of $800 million in aggregate principal amount of 5.75% senior notes due 2025.

Other, net

Other, net for the three months ended September 30, 2018 was $22.9 million of expense, which included a loss on debt buybacks of $10.5 million, net loss on sales and disposals of assets of approximately $4.8 million, transaction related costs primarily related to the Tesco acquisition of approximately $1.8 million, foreign currency exchange losses of $1.6 million and an increase in litigation reserves of $1.4 million.

Other, net for the three months ended September 30, 2017 was $5.6 million of expense, which included a net loss on sales and disposals of assets of approximately $10.0 million and transaction related costs of approximately $3.2 million. These losses were partially offset by a decrease in our litigation reserves of $2.2 million and foreign currency exchange gains of $0.8 million.

Income tax rate

Our worldwide effective tax rate for the three months ended September 30, 2018 was (12.6%) compared to 11.0% for the three months ended September 30, 2017. The change in effective tax rate was a result of a change in our geographic mix of pre-tax earnings (losses), primarily due to pre-tax earnings in certain high tax jurisdictions causing a net income tax despite a consolidated pre-tax loss. This resulted in a negative tax rate for the quarter. 

In certain jurisdictions we have recognized deferred tax assets and liabilities. Judgment and assumptions are required in determining whether deferred tax assets will be fully or partially utilized. When we estimate that all or some portion of certain deferred tax assets such as net operating loss carryforwards will not be utilized, we establish a valuation allowance for the amount we determine to be more likely than not unrealizable. We continually evaluate strategies that could allow for future utilization of our deferred tax assets. Any change in the ability to utilize such deferred tax assets will be accounted for in the period of the event affecting the valuation allowance. If facts and circumstances cause us to change our expectations regarding future tax consequences, the resulting adjustments could have a material effect on our financial results or cash flow. The area at greatest risk is our Canada Drilling operations. At this time, we consider it more likely than not that we will have sufficient taxable income in the future that will allow us to realize the deferred tax assets that we have recognized. However, it is possible that some of our recognized deferred tax assets, relating to net operating loss carryforwards, could expire unused or could carryforward indefinitely without utilization. Therefore, unless we are able to generate sufficient taxable income from our component operations, a substantial valuation allowance to reduce our deferred tax assets may be required, which would materially increase our

46

tax expense in the period the allowance is recognized and materially adversely affect our results of operations and statement of financial condition.  

Our accounting for the U.S. Tax Reform Act, enacted on December 22, 2017, is incomplete. As noted at year-end, however, we were able to reasonably estimate certain effects and, therefore, recorded a provisional adjustment to revalue deferred tax assets and liabilities from 35 percent to 21 percent associated with the reduction in the U.S. corporate income tax rate. In addition, as noted at year-end, we continue to believe the other provisions of the Tax Reform Act do not have a material impact on our consolidated financial statements. The Company has not revised any of the 2017 provisional estimates under Staff Accounting Bulletin No. 118 (“SAB 118”), but is continuing to gather information and we are waiting on further guidance from the Internal Revenue Service, the SEC and the FASB. We are continuing to gather additional information to complete our accounting for these items and expect to complete our accounting within the prescribed measurement period.

Discontinued Operations

Our discontinued operations for the three months ended September 30, 2018 and 2017 consisted of our historical wholly owned oil and gas businesses. Income (loss) from discontinued operations for the three months ended September 30, 2018 was a loss of $13.9 million compared to a loss of $27.1 million for the three months ended September 30, 2017. During the three months ended September 30, 2018 and 2017, we recognized impairment charges of $16.5 million and $35.3 million, respectively, due to the deterioration of economic conditions in the dry gas market in western Canada.

Comparison of the nine months ended September 30, 2018 and 2017

Operating revenues for the nine months ended September 30, 2018 totaled $2.3 billion, representing an increase of $419.5 million, or 23%, compared to the nine months ended September 30, 2017. We experienced an increase in operating revenue across all of our operating segments as activity has increased across the U.S. and international markets, as evidenced by the 8% increase in average rigs working across our global fleet during the nine months ended September 30, 2018 compared to the same period in 2017. Additionally, we benefited from incremental operating revenues of approximately $114.7 million as a result of our acquisition of Tesco.

Net loss from continuing operations attributable to Nabors common shareholders totaled $450.9 million ($1.39 per diluted share) for the nine months ended September 30, 2018 compared to a net loss from continuing operations attributable to Nabors common shareholders of $387.4 million ($1.35 per diluted share) for the nine months ended September 30, 2017, or a $63.5 million increase in the net loss. Although our segments’ adjusted operating income improved by approximately $166.5 million compared to the prior period, our net loss was adversely impacted by a $63.7 million loss on the sale of three jackup rigs as well as a $117.1 million increase in income tax expense.

General and administrative expenses for the nine months ended September 30, 2018 totaled $209.2 million, representing an increase of $17.1 million or 9%, compared to the nine months ended September 30, 2017. This is reflective of a slight increase in salaries and other compensation as well as increases in headcount as a result of increased activity, including entry into new markets from the Company’s acquisition of Tesco in the fourth quarter of 2017.

Research and engineering expenses for the nine months ended September 30, 2018 totaled $42.7 million, representing an increase of $6.6 million, or 18%, compared to the nine months ended September 30, 2017. The increase is a result of increased efforts towards a number of strategic research and engineering projects as the market rebalanced and activity increased.

Depreciation and amortization expense for the nine months ended September 30, 2018 was $640.2 million, representing an increase of $11.4 million, or 2%, compared to the nine months ended September 30, 2017. The slight increase was primarily due the increased number of rigs that were working during the period, which results in a higher active depreciation rate coupled with incremental depreciation expense associated with the acquisition of Tesco.

On an annual period, one rig operating 182.5 days represents approximately 0.5 average rigs working for the year.

(2) The number is so large that it is not meaningful.

U.S. Drilling

Operating results increased during the nine months ended September 30, 2018 compared to the corresponding 2017 period primarily due to a 13% increase in the average number of rigs working, and operating at higher dayrates as market prices continued to improve. Additionally, this segment benefitted from incremental operating results from the contribution of one of our new MODS-400 rigs in the Gulf of Mexico, further contributing to the $207.4 million, or 36%, increase in operating revenues.

Canada Drilling

Operating results improved during the nine months ended September 30, 2018 compared to the corresponding 2017 period primarily due to a 3% increase in the average number of rigs working. Additionally, this segment benefited from the mix of higher margin active rigs during the period supplemented by an increase in dayrates as market prices have improved.

International Drilling

Operating revenue increased slightly during the nine months ended September 30, 2018 compared to the corresponding 2017 period primarily due to the increase in activity during the period. Our results for the nine months ended September 30, 2017 were unfavorably impacted by a loss of revenue and increased costs related to downtime incurred to perform structural work on many of our rigs in our largest international market.  

48

Drilling Solutions

Operating results increased during the nine months ended September 30, 2018 compared to the corresponding 2017 period primarily due to the significant increase in drilling activity in the U.S. and in the demand for our products and services, including Tubular Services and Performance Tools. This segment benefited from incremental operating revenues of approximately $60.8 million related to the addition of our Tubular Services product lines as a result of the acquisition of Tesco.

Rig Technologies

Operating revenues increased during the nine months ended September 30, 2018 compared to the corresponding 2017 period primarily due to approximately $53.9 million in incremental revenue as a result of the acquisition of Tesco during the fourth quarter of 2017. However, operating income (loss) was adversely impacted by the mix between higher margin capital equipment sales and other lower margin activity.

Other Financial Information

Interest expense

Interest expense for the nine months ended September 30, 2018 was $173.4 million, representing an increase of $7.6 million, or 5%, compared to the nine months ended September 30, 2017. The increase was primarily due to the additional interest expense related to the January 2018 issuance of $800 million in aggregate principal amount of 5.75% senior notes due 2025. This increase was partially offset by a reduction in interest expense due to the repayment of the 6.15% senior notes due February 2018 and 9.25% senior notes due January 2019.

Other, net

Other, net for the nine months ended September 30, 2018 was $114.6 million of expense, which included net losses on sales and disposals of assets of approximately $74.4 million, primarily related to a $63.7 million loss on the sale of three jackup rigs, transaction related costs of $14.7 million, loss on debt buybacks of $10.5 million, an increase in litigation reserves of $9.7 million and foreign currency exchange losses of $7.9 million.

Other, net for the nine months ended September 30, 2017 was $29.2 million of expense, which included a loss on debt buybacks of $16.0 million, net losses on sales and disposals of assets of approximately $10.1 million, transaction related costs of $5.1 million and foreign currency exchange losses of $1.7 million.

Income tax rate

Our worldwide effective tax rate for the nine months ended September 30, 2018 was (15.3%) compared to 13.5% for the nine months ended September 30, 2017. The change in effective tax rate was a result of a change in our geographic mix of pre-tax earnings (losses), primarily due to pre-tax earnings in certain high tax jurisdictions causing a net income tax despite a consolidated pre-tax loss. This resulted in a negative tax rate for the nine months ended September 30, 2018. 

Discontinued Operations

Our discontinued operations for the nine months ended September 30, 2018 and 2017 consisted of our historical wholly owned oil and gas businesses. Income (loss) from discontinued operations for the nine months ended September 30, 2018 was a loss of $14.6 million compared to a loss of $43.1 million for the nine months ended September 30, 2017. During the nine months ended September 30, 2018 and 2017, we recognized impairment charges of $16.5 million and $35.3 million, respectively, due to the deterioration of economic conditions in the dry gas market in western Canada. Additionally, our net loss for the nine months ended September 30, 2017 included a $16.5 million charge related to the settlement of litigation associated with our previously owned Ramshorn International properties.

Liquidity and Capital Resources

Financial Condition and Sources of Liquidity

Our primary sources of liquidity are cash and investments and availability under our 2012 revolving credit facility maturing in 2020 (the “2012 Revolving Credit Facility”) and our new 2018 revolving credit facility maturing in 2023 (the “2018 Revolving Credit Facility”). As of September 30, 2018, we had cash and short-term investments of $388.6 million and working capital of $786.6 million. As of December 31, 2017, we had cash and short-term investments of $365.4 million and working capital of $527.9 million. At September 30, 2018, we had $215.0 million of borrowings outstanding under our 2012 Revolving Credit Facility.

In January 2018, Nabors Delaware completed an offering of $800 million aggregate principal amount of 5.75% senior unsecured notes due February 1, 2025, which are fully and unconditionally guaranteed by Nabors. A portion of the proceeds from this offering were used to repay indebtedness of Nabors and its subsidiaries, including all of Nabors Delaware’s outstanding 6.15% senior notes due February 2018. The remaining proceeds not used for such purposes were allocated for general corporate purposes, including to repay amounts outstanding under the commercial paper program and to repurchase or repay other indebtedness.

In May 2018, we issued 35,000,000 shares of common stock at a price to the public of $7.75 per share and 5,750,000 shares (including the underwriters option for 750,000 shares) of 6% Series A Mandatory Convertible Preferred Stock (the “mandatory convertible preferred shares”), par value $.001 per share, with a liquidation preference of $50 per share. In connection with the common shares offering, in June 2018 the underwriters exercised in full their option to purchase 5,250,000 additional common shares. Nabors received aggregate net proceeds of approximately $580.6 million from these offerings after deducting underwriting discounts, commissions, and offering expenses. The net proceeds from these offerings were used to repay amounts outstanding under the revolving credit facility, which we may re-borrow from time to time for the repayment of other indebtedness, and for general corporate purposes.

The dividends on the mandatory convertible preferred shares will be payable on a cumulative basis. At issuance, each share of the mandatory convertible preferred shares was automatically convertible into between 5.3763 and 6.4516 of our common shares based on the average share price over a period of twenty consecutive trading days ending prior to May 1, 2021, subject to anti-dilution adjustments. In connection with the dividend on our common shares paid on October 2, 2018, the conversion rate for each share of the mandatory convertible preferred shares was adjusted to between 5.4735 and 6.5683 of our common shares.

On October 11, 2018, Nabors Delaware, Nabors Drilling Canada Limited, Nabors and certain of Nabors’ wholly owned subsidiaries entered into the new 2018 Revolving Credit Facility. The 2018 Revolving Credit Facility has a borrowing capacity of $1.267 billion and is fully and unconditionally guaranteed by Nabors and certain of its wholly owned subsidiaries. The 2018 Revolving Credit Facility matures at the earlier of (a) October 11, 2023 and (b) July 19, 2022, if any of Nabors Delaware’s existing 5.5% senior notes due January 2023 remain outstanding as of such date. The 2018 Revolving Credit Facility can be used for general corporate purposes, including capital expenditures and working capital. As of the date of this report, we had no borrowings under the 2018 Revolving Credit Facility.

In connection with entering into the 2018 Revolving Credit Facility, on October 11, 2018, we entered into Amendment No. 3 to the 2012 Revolving Credit Facility (the “Amendment”). The Amendment, among other things, reduces the overall commitments available to $666.25 million and provides for certain lenders to exit the facility.

We had 15 letter-of-credit facilities with various banks as of September 30, 2018. Availability under these facilities as of September 30, 2018 was as follows:

	September 30,
	2018
	(In thousands)
Credit available	$	759,321
Less: Letters of credit outstanding, inclusive of financial and performance guarantees		112,092
Remaining availability	$	647,229

Our gross debt to capital ratio was 0.56:1 as of September 30, 2018 and 0.58:1 as of December 31, 2017. Our net debt to capital ratio was 0.53:1 as of September 30, 2018 and 0.56:1 as of December 31, 2017. The gross debt to capital

50

ratio is calculated by dividing total debt by total capitalization (total debt plus shareholders’ equity). The net debt to capital ratio is calculated by dividing net debt by net capitalization. Net debt is defined as total debt minus the sum of cash and cash equivalents and short-term investments. Net capitalization is defined as net debt plus shareholders’ equity. Availability under both the 2012 Revolving Credit Facility and the 2018 Revolving Credit Facility is subject to a covenant not to exceed a net debt to capital ratio of 0.60:1. In addition, availability under the new 2018 Revolving Credit Facility is subject to a covenant that during any period in which Nabors Delaware fails to maintain an investment grade rating from at least two ratings agencies, the guarantors under the facility and their subsidiaries we will be required to maintain an asset to debt coverage ratio of at least 2.50:1. As of September 30, 2018, our asset to debt coverage ratio would have been 3.90:1. The asset to debt coverage ratio is calculated by dividing (x) drilling-related fixed assets wholly owned by certain of Nabors’ subsidiaries that are guaranteeing the 2018 Revolving Credit Facility (the “2018 Revolver Guarantors”) or wholly owned subsidiaries of the 2018 Revolver Guarantors by (y) total debt of the 2018 Revolver Guarantors (subject to certain exclusions).

As of the date of this report, we were in compliance with all covenants under the 2018 Revolving Credit Facility and 2012 Revolving Credit Facility. If we fail to perform our obligations under the covenants, the revolving credit commitments under the 2012 Revolving Credit Facility and the 2018 Revolving Credit Facility could be terminated, and any outstanding borrowings under the facilities could be declared immediately due and payable. We have contemplated various alternative actions that could be pursued if we believe a violation of the covenant seemed likely to occur in the future.  These actions include reductions in discretionary capital or other types of controllable expenditures, monetization of assets, amending or renegotiating the revolving credit agreement, accessing capital markets through a variety of alternative methods, or any combination of these alternatives. The gross debt to capital ratio, the net debt to capital ratio and the asset to debt coverage ratio are not measures of operating performance or liquidity defined by U.S. GAAP and may not be comparable to similarly titled measures presented by other companies.

Our interest coverage ratio was 3.1:1 as of September 30, 2018 and 2.4:1 as of December 31, 2017. The interest coverage ratio is a trailing 12-month quotient of the sum of operating revenues, direct costs, general administrative expenses and research and engineering expenses divided by interest expense. The interest coverage ratio is not a measure of operating performance or liquidity defined by U.S. GAAP and may not be comparable to similarly titled measures presented by other companies.

Our ability to access capital markets or to otherwise obtain sufficient financing may be affected by our senior unsecured debt ratings as provided by the major credit rating agencies in the United States and our historical ability to access these 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 maturity, exchange or purchase of our notes and our debt facilities, loss of availability of our revolving credit facility, 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. The major U.S. credit rating agencies have downgraded our senior unsecured debt rating to non-investment grade. These and further ratings downgrades could adversely impact our ability to access debt markets in the future, increase the cost of future debt, and potentially require us to post letters of credit for certain obligations.

Our current cash and investments, projected cash flows from operations, proceeds from equity or debt issuances, and our revolving credit facility are expected to adequately finance our purchase commitments, capital expenditures, acquisitions, scheduled debt service requirements, and all other expected cash requirements for the next 12 months.

Future Cash Requirements

We expect capital expenditures over the next 12 months to be approximately $0.4 billion. Purchase commitments outstanding at September 30, 2018 totaled approximately $228.7 million, primarily for rig-related enhancements, new rig equipment, as well as sustaining capital expenditures, other operating expenses and purchases of inventory. We can reduce planned expenditures if necessary or increase them if market conditions and new business opportunities warrant it. 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.

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

51

debt or our common shares. Future acquisitions may be funded 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 material changes to the contractual cash obligations table that was included in our 2017 Annual Report.

On August 25, 2015, our Board of Directors authorized a share repurchase program (the “program”) under which we may repurchase, from time to time, up to $400 million of our common shares by various means, including in the open market or in privately negotiated transactions. This authorization does not have an expiration date and does not obligate us to repurchase any of our common shares. Since establishing the program, we have repurchased 14.0 million of our common shares for an aggregate purchase price of approximately $119.4 million under this program. As of September 30, 2018, the remaining amount authorized under the program that may be used to purchase shares was $280.6 million. The repurchased shares, which are held by our subsidiaries, are registered and tradable subject to applicable securities law limitations and have the same voting and other rights as other outstanding shares. As of September 30, 2018, our subsidiaries held 52.8 million of our common shares.

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 and may involve material amounts.

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 decreases in the price of oil or natural gas 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 or acquisitions, purchases and sales of investments, dividends, loans, issuances and repurchases of debt and of our common shares are within our control and are adjusted as necessary based on market conditions. We discuss our cash flows for the nine months ended September 30, 2018 and 2017 below.

Operating Activities.  Net cash provided by operating activities totaled $76.9 million during the nine months ended September 30, 2018, compared to net cash used of $36.1 million during the corresponding 2017 period. Operating cash flows are our primary source of capital and liquidity. The increase in cash flows from operations is primarily attributable to increases in activity and margins.  Additionally, changes in working capital items such as collection of receivables, other deferred revenue arrangements and payments of operating payables and interest payments are significant factors affecting operating cash flows. Changes in working capital items used $300.7 million and $231.2 million in cash during the nine months ended September 30, 2018 and 2017, respectively.  

Investing Activities.  Net cash used for investing activities totaled $250.0 million during the nine months ended September 30, 2018 compared to $461.0 million during the corresponding 2017 period. Our 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 nine months ended September 30, 2018 and 2017, we used cash for capital expenditures totaling $339.0 million and $448.9 million, respectively. Additionally, we received net proceeds of $86.7 million from the sale of assets during the nine months ended September 30, 2018. This was primarily comprised of the cash proceeds received from the sale of three jackup rigs.

Financing Activities.  Net cash provided by financing activities totaled $187.4 million during the nine months ended September 30, 2018 compared to net cash provided of $423.8 million during the corresponding 2017 period. During the nine months ended September 30, 2018, we received net proceeds of $786.8 million in connection with the issuance of our 5.75% senior notes and $580.2 million from the issuance of common and mandatory convertible preferred shares. This was partially offset by the repayment of the remaining balances of our 6.15% and 9.25% senior notes of $774.8 million and $335.0 million on our revolving credit facility and commercial paper program. Additionally, we paid dividends totaling $61.3 million to our common and preferred shareholders.

Other Matters

Recent Accounting Pronouncements

See Note 2 — Summary of Significant Accounting Policies.

Off-Balance Sheet Arrangements (Including Guarantees)

We are a party to 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 bonds. In addition, we have provided indemnifications, which serve as guarantees, to some third parties. These guarantees include indemnification provided by us 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
	2018		2019	2020	Thereafter	Total
	(In thousands)
Financial standby letters of credit and other financial surety instruments	$	27,518	149,692	40	—	$	177,250

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We may be exposed to market risks arising from the use of financial instruments in the ordinary course of business as discussed in our 2017 Annual Report. There were no material changes in our exposure to market risk during the nine months ended September 30, 2018 from those disclosed in our 2017 Annual Report.

ITEM 4. CONTROLS AND PROCEDURES

We maintain a set of disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d‑15(e) under the Exchange Act) 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, and that such information is accumulated and communicated to management as appropriate to allow timely decisions regarding required disclosure. 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 Chief Executive Officer and the Chief Financial Officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures as of the end of the period covered by this report. Based on this evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this report

There were no changes in our internal control over financial reporting during the quarter ended September 30, 2018 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

53

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 condensed consolidated financial position or cash flows, although they could have a material adverse effect on our results of operations for a particular reporting period. See Note 7 — Commitments and Contingencies for a description of such proceedings.

ITEM 1A. RISK FACTORS

Except as set forth below, there have been no material changes from the risk factors previously disclosed in Part 1, Item 1A, of our 2017 Annual Report, Form 10-Q for the quarter ended March 31, 2018 and Form 10-Q for the quarter ended June 30, 2018, which in addition to the information set forth elsewhere in this report, should be carefully considered when evaluating us. These risks are not the only risks we face. Additional risks not presently known to us or that we currently deem immaterial may also impair our business.

Our financial and operating flexibility could be affected by our long-term debt and other financial commitments.

As of September 30, 2018, we had approximately $3.8 billion in outstanding debt, resulting in a gross debt to capital ratio of 0.56:1, a net debt to capital ratio of 0.53:1 and an asset to debt coverage ratio of approximately 3.90:1.

Availability under both the 2012 Revolving Credit Facility and the 2018 Revolving Credit Facility is subject to a covenant not to exceed a net debt to capital ratio of 0.60:1. In addition, availability under the new 2018 Revolving Credit Facility is subject to a covenant to maintain an asset to debt coverage ratio of at least 2.50:1. The gross debt to capital ratio is calculated by dividing total debt by total capitalization (total debt plus shareholders’ equity). The net debt to capital ratio is calculated by dividing net debt (total debt minus the sum of cash and cash equivalents and short-term investments) by net capitalization (net debt plus shareholders’ equity).  The asset to debt coverage ratio is calculated by dividing (x) drilling-related fixed assets wholly owned by the 2018 Revolver Guarantors or wholly owned subsidiaries of the 2018 Revolver Guarantors by (y) total debt of the 2018 Revolver Guarantors (subject to certain exclusions).  The asset to debt coverage ratio applies only during any period which Nabors Delaware fails to maintain an investment grade rating from at least two ratings agencies. The gross debt to capital ratio, the net debt to capital ratio and the asset to debt coverage ratio are not measures of operating performance or liquidity defined by GAAP and may not be comparable to similarly titled measures presented by other companies.  The gross debt to capital ratio and the net debt to capital ratio are methods for calculating the amount of leverage a company has in relation to its capital. 

As of September 30, 2018, we would have been able to borrow $1.267 billion in aggregate under our 2018 Revolving Credit Facility, subject to compliance with the conditions and covenants contained therein and an additional $451.25 million in aggregate under our 2012 Revolving Credit Facility, subject to compliance with the conditions and covenants contained therein.

We also have various financial commitments, such as leases, firm transportation and processing, contracts and purchase commitments. Our ability to service our debt and other financial obligations depends in large part upon the level of cash flows generated by our operating subsidiaries’ operations, our ability to monetize and/or divest non-core assets, availability under our unsecured revolving credit facilities and our ability to access the capital markets and/or other sources of financing. If we cannot repay or refinance our debt as it becomes due, we may be forced to sell assets or reduce funding in the future for working capital, capital expenditures and general corporate purposes.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

We withheld the following shares of our common stock to satisfy tax withholding obligations in connection with grants of stock awards during the three months ended September 30, 2018 from the distributions described below. These shares may be deemed to be “issuer purchases” of shares that are required to be disclosed pursuant to this Item, but were not purchased as part of a publicly announced program to purchase common shares:

					Approximated
				Total Number	Dollar Value of

August 1 - August 31	2	$	6.00	—	280,645
September 1 - September 30	3	$	6.17	—	280,645

(1) Shares were withheld from employees and directors to satisfy certain tax withholding obligations due in connection with grants of shares under our 2003 Employee Stock Plan, the 2013 Stock Plan and the 2016 Stock Plan. Each of the 2016 Stock Plan, the 2013 Stock Plan, the 2003 Employee Stock Plan and the 1999 Stock Option Plan for Non-Employee Directors provide for the withholding of shares to satisfy tax obligations, but do not specify a maximum number of shares that can be withheld for this purpose. These shares were not purchased as part of a publicly announced program to purchase common shares.

(2) In August 2015, our Board of Directors authorized a share repurchase program under which we may repurchase up to $400 million of our common shares in the open market or in privately negotiated transactions. Through September 30, 2018, we repurchased 14.0 million of our common shares for an aggregate purchase price of approximately $119.4 million under this program. As of September 30, 2018, we had $280.6 million that remained authorized under the program that may be used to repurchase shares. The repurchased shares, which are held by our subsidiaries, are registered and tradable subject to applicable securities law limitations and have the same voting, dividend and other rights as other outstanding shares. As of September 30, 2018, our subsidiaries held 52.8 million of our common shares.
