Our business depends, to a large degree, on the level of spending by oil and gas
companies for exploration, development and production activities. Therefore, a
sustained increase or decrease in the price of oil or natural gas, that

has a material impact on exploration, development and production activities, could also materially affect our financial position, results of operations and cash flows. The above description of risks and uncertainties is by no means all-inclusive but highlights certain factors that we believe are important for your consideration. For a more detailed description of risk factors that may affect us or our industry, please refer to Item 1A. - Risk Factors in our 2021 Annual Report. 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 are a leading provider of advanced technology for the energy industry. With operations in over 15 countries, Nabors has established a global network of people, technology and equipment to deploy solutions that deliver safe, efficient and sustainable energy production. By leveraging its core competencies, particularly in drilling, engineering, automation, data science and manufacturing, Nabors aims to innovate the future of energy and enable the transition to a lower carbon world.
Outlook
The demand for our services and products is a function of the level of spending by oil and gas companies for exploration, development and production activities. The level of exploration, development and production activities is to a large extent tied to the prices of oil and natural gas, which can fluctuate significantly, are highly volatile and tend to be highly sensitive to supply and demand cycles. Additionally, some oil and gas companies may intentionally limit their capital spending to a percentage of their operating cash flows which may differ from how they have historically made capital allocation decisions. During 2020, global oil markets experienced unprecedented volatility. As a result, we experienced a significant reduction in demand for our services throughout 2020 and into 2021, both in the US and in many international markets. The US drilling rig market began to stabilize during the second half of 2020 and has improved at a measured rate since 2020 through the first three quarters of 2022. We expect continued increases in activity throughout the remainder of 2022 and 2023 for the US market. In our International markets since 2020, we have seen a substantial resumption of overall activity to near pre-COVID-19 levels. In certain key markets, activity has been restored to pre-COVID levels. We are becoming increasingly engaged with new energy solution opportunities, specifically focused around the reduction of carbon emissions, geothermal technologies and energy storage. Additionally, the Company continues to invest in technologies and solutions that will support the new energy transition. We expect to see continued growth in these areas as new energy solutions expand. More recently, several global commodity markets, including oil and gas, have been impacted by the effects of the war inUkraine . These consequences include severe economic sanctions against the Russian government as well as certain Russian businesses and individuals, in addition to a reorientation of the global sources of oil and gas supply and a significant increase in the related commodity prices. Government actions, as well as those by large producers, also continue to impact energy markets. Although higher commodity prices have historically led to an increase in oilfield activity, the ultimate outcome of these events and the impact on our business remains uncertain.
Recent Developments
2022 Credit Agreement
OnJanuary 21, 2022 , we entered into a revolving credit agreement betweenNabors Delaware , the guarantors from time to time party thereto, the issuing banks (the "Issuing Banks") and other lenders party thereto (the "Lenders") andCitibank, N.A ., as administrative agent (the "2022 Credit Agreement"). The 2022 Credit Agreement replaced the 2018 Revolving Credit Facility. Under the 2022 Credit Agreement, the Lenders have committed to provide up to an aggregate principal amount at any time outstanding not in excess of$350.0 million (with an accordion feature for an additional$100.0 million ) toNabors Delaware under a secured revolving credit facility, including sub-facilities provided by certain 26 Table of Contents of the Lenders for letters of credit in an aggregate principal amount at any time outstanding not in excess of$100.0 million . The facility matures on the earlier of (a)January 21, 2026 and (b) (i) to the extent any principal amount ofNabors Delaware's existing 5.1% senior notes due 2023 or 5.75% senior notes due 2025 remains outstanding on the date that is 90 days prior to the applicable maturity date for such indebtedness, then such 90th day or (ii) to the extent 50% or more of the outstanding (as of the closing date) aggregate principal amount of the 0.75% senior exchangeable notes due 2024 remains outstanding and not refinanced or defeased on the date that is 90 days prior to the maturity date for such indebtedness, then such 90th day.
Financial Results
Comparison of the three months ended
Operating revenues for the three months endedSeptember 30, 2022 totaled$694.1 million , representing an increase of$170.0 million , or 32%, compared to the three months endedSeptember 30, 2021 . All of our operating segments, with the exception of Canada Drilling due to its sale, experienced an increase in operating revenues over this period. For a more detailed description of operating results see Segment Results of Operations below. Net loss from continuing operations attributable to Nabors common shareholders totaled$13.8 million ($1.80 per diluted share) for the three months endedSeptember 30, 2022 compared to a net loss from continuing operations attributable to Nabors common shareholders of$122.5 million ($15.79 per diluted share) for the three months endedSeptember 30, 2021 , or a$108.7 million decrease in the net loss. The majority of the decrease in net loss is attributable to improved market conditions, which has resulted in improved adjusted operating income in all our segments from the prior year, together with$34.0 million of mark-to-market gains from the common stock warrants during the third quarter of 2022. General and administrative expenses for the three months endedSeptember 30, 2022 totaled$57.6 million , representing an increase of$4.7 million , or 9%, compared to the three months endedSeptember 30, 2021 . This is reflective of increases in workforce costs and general operating costs as market conditions have improved and operating levels have increased. Research and engineering expenses for the three months endedSeptember 30, 2022 totaled$13.4 million , representing an increase of$3.9 million , or 41%, compared to the three months endedSeptember 30, 2021 . This is primarily reflective of an increase in research and development activities, along with increased engineering support costs for the higher general operating activity levels, as market conditions have improved. Depreciation and amortization expense for the three months endedSeptember 30, 2022 was$169.9 million , representing a decrease of$3.5 million , or 2%, compared to the three months endedSeptember 30, 2021 . The decrease is attributable to the combination of (a) a reduction in depreciation as a result of the many assets that have recently reached the end of their useful lives and (b) limited capital expenditures over recent years. 27

Liquidity and Capital Resources
Financial Condition and Sources of Liquidity
Our primary sources of liquidity are cash and investments, availability under our revolving credit facility and cash generated from operations. As ofSeptember 30, 2022 , we had cash and short-term investments of$425.1 million and working capital of$406.7 million . As ofDecember 31, 2021 , we had cash and short-term investments of$991.5 million and working capital of$1.0 billion .
At
The 2022 Credit Agreement requires us to maintain an interest coverage ratio (EBITDA/interest expense), which increases on a quarterly basis, and a minimum guarantor value, requiring the guarantors (other than the Company) and their subsidiaries to own at least 90% of the consolidated property, plant and equipment of the Company. Additionally, the Company is subject to certain covenants (which are subject to certain exceptions) and include, among others, (a) a covenant restricting our ability to incur liens (subject to the additional liens basket of up to$150.0 million ), (b) a covenant restricting its ability to pay dividends or make other distributions with respect to its capital stock and to repurchase certain indebtedness, and (c) a covenant restricting the ability of the Company's subsidiaries to incur debt (subject to the grower basket of up to$100.0 million ). As ofSeptember 30, 2022 , we were in compliance with both the interest coverage ratio and the minimum guarantor value requirements under the 2022 Credit Agreement. We also had$64.8 million of letters of credit outstanding under the 2022 Credit Agreement. As of the date of this report, we are in compliance with all covenants under the 2022 Credit Agreement. If we fail to perform our obligations under the covenants, the revolving credit commitments under the 2022 Credit Agreement could be terminated, and any outstanding borrowings under the facilities could be declared immediately due and payable. If necessary, we have the ability to manage our covenant compliance by taking certain actions including 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. We expect to remain in compliance with all covenants under the 2022 Credit Agreement during the twelve month period following the date of this report based on our current operational and financial projections. However, we can make no assurance of continued compliance if our current projections or material underlying assumptions prove to be incorrect. If we fail to comply with the covenants, the revolving credit commitment could be terminated, and any outstanding borrowings under the facility could be declared immediately due and payable. 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 inthe 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 facilities and our A/R Facility (see-Accounts Receivable Purchase and Sales Agreements, below), 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 majorU.S. credit rating agencies have previously downgraded our senior unsecured debt rating to non-investment grade. These and any 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. 32

Accounts Receivable Purchase and Sales Agreements
OnSeptember 13, 2019 , we entered into an accounts receivables sales agreement (the "A/R Sales Agreement") and an accounts receivables purchase agreement (the "A/R Purchase Agreement" and, together with the A/R Sales Agreement, the "A/R Facility"), whereby the originators sold or contributed, and will on an ongoing basis continue to sell or contribute, certain of their domestic trade accounts receivables to a wholly-owned, bankruptcy-remote special purpose entity ("SPE"). The SPE in turn, sells, transfers, conveys and assigns to third-party financial institutions ("Purchasers"), all the rights, title and interest in and to its pool of eligible receivables.
On
OnJune 27, 2022 , we entered into the Third Amendment to the A/R Purchase Agreement which extended the term of the Purchase Agreement toAugust 13, 2024 and increased the commitments of the Purchasers from$150 million to$250 million . Subject to Purchaser approval, the A/R Purchase Agreement contains the possibility of being increased up to$300 million . The expiration of the A/R Purchase Agreement can be accelerated toNovember 16, 2022 , if any of the 5.5% Senior Notes due 2023 remain outstanding as of such date; toJune 17, 2023 if any of the 5.1% Senior Notes remain outstanding as of such date; or, toOctober 17, 2023 if 50% or more of the outstanding aggregate principal amount of the 0.75% Senior Exchangeable Notes remain outstanding and not refinanced as of such date. OnOctober 13, 2022 , we issued a Notice of Optional Full Redemption for all of the 5.5% Senior Notes due 2023 effectiveNovember 15, 2022 . The amount available for purchase under the A/R Facility fluctuates over time based on the total amount of eligible receivables generated during the normal course of business after excluding excess concentrations and certain other ineligible receivables. The maximum purchase commitment of the Purchasers under the A/R Facility is approximately$250.0 million and the amount of receivables purchased by the third-party Purchasers as ofSeptember 30, 2022 was$167.0 million .

Future Cash Requirements
Our current cash and investments, projected cash flows from operations, proceeds from equity or debt issuances and the facilities under our 2022 Credit Agreement are expected to adequately finance our purchase commitments, capital expenditures, acquisitions, scheduled debt service requirements, and all other expected cash requirements for at least the next 12 months. However, we can make no assurances that our current operational and financial projections will prove to be correct. A sustained period of highly depressed oil and natural gas prices could have a significant effect on our customers' capital expenditure spending and therefore our operations, cash flows and liquidity. Purchase commitments outstanding atSeptember 30, 2022 totaled approximately$272.5 million , primarily for 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. 33
Table of Contents
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 that were included in our 2021 Annual Report.
OnAugust 25, 2015 , our Board authorized a share repurchase program (the "program") under which we may repurchase, from time to time, up to$400.0 million of our common shares by various means, including in the open market or in privately negotiated transactions. Authorization for the program, which was renewed inFebruary 2019 , 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 0.3 million of our common shares for an aggregate purchase price of approximately$121.1 million under this program. 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 ofSeptember 30, 2022 , the remaining amount authorized under the program that may be used to purchase shares was$278.9 million . As ofSeptember 30, 2022 , our subsidiaries held 1.1 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 endedSeptember 30, 2022 and 2021 below. Operating Activities. Net cash provided by operating activities totaled$301.1 million during the nine months endedSeptember 30, 2022 , compared to net cash provided of$326.5 million during the corresponding 2021 period. Operating cash flows are our primary source of capital and liquidity.
