NABORS INDUSTRIES LTD. April 24, 2024 1Q 2024 Earnings Presentation

N A B O R S . C O M We often discuss expectations regarding our future markets, demand for our products and services, and our performance in our annual, quarterly, and current reports, press releases, and other written and oral statements. Such statements, including statements in this document that relate to matters that are not historical facts, are “forward-looking statements” within the meaning of the safe harbor provisions of Section 27A of the U.S. Securities Act of 1933 and Section 21E of the U.S. Securities Exchange Act of 1934. These “forward-looking statements” are based on our analysis of currently available competitive, financial and economic data and our operating plans. They are inherently uncertain, and investors should recognize that events and actual results could turn out to be significantly different from our expectations. Factors to consider when evaluating these forward-looking statements include, but are not limited to: • geopolitical events, pandemics (including COVID-19) and other macro-events and their respective and collective impact on our operations as well as oil and gas markets and prices; • fluctuations and volatility in worldwide prices of and demand for oil and natural gas; • fluctuations in levels of oil and natural gas exploration and development activities; • fluctuations in the demand for our services; • competitive and technological changes and other developments in the oil and gas and oilfield services industries; • our ability to renew customer contracts in order to maintain competitiveness; • the existence of operating risks inherent in the oil and gas and oilfield services industries; • the possibility of the loss of one or a number of our large customers; • the amount and nature of our future capital expenditures and how we expect to fund our capital expenditures; • The occurrence of cybersecurity incidents, attacks and other breaches to our information technology systems; • the impact of long-term indebtedness and other financial commitments on our financial and operating flexibility; • our access to and the cost of capital, including the impact of a further downgrade in our credit rating, covenant restrictions, availability under our revolving credit facility, and future issuances of debt or equity securities and the global interest rate environment; • our dependence on our operating subsidiaries and investments to meet our financial obligations; Forward Looking Statements NABORS INDUSTRIES 2 • our ability to retain skilled employees; • our ability to complete, and realize the expected benefits of, strategic transactions; • changes in tax laws and the possibility of changes in other laws and regulation; • the possibility of changes to U.S. trade policies and regulations including the imposition of trade embargoes or sanctions; and • global views on and the regulatory environment related to energy transition and our ability to implement our energy transition initiatives; • potential long-lived asset impairments • the possibility of changes to U.S. trade policies and regulations including the imposition of trade embargoes, sanctions or tariffs; and • general economic conditions, including the capital and credit markets. Our businesses depend, to a large degree, on the level of spending by oil and gas companies for exploration, development and production activities. Therefore, sustained lower oil or natural gas prices that have a material impact on exploration, development or production activities could also materially affect our financial position, results of operations and cash flows. The above description of risks and uncertainties is by no means all-inclusive but is designed to highlight what we believe are important factors to consider. For a discussion of these factors and other risks and uncertainties, please refer to our filings with the Securities and Exchange Commission ("SEC"), including those contained in our Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q, which are available at the SEC's website at www.sec.gov. We undertake no obligation to publicly update or revise any forward-looking statement as a result of new information, future events or otherwise, except as otherwise required by law. Non-GAAP Financial Measures This presentation refers to certain “non-GAAP” financial measures, such as adjusted EBITDA, net debt, adjusted gross margin and adjusted free cash flow. The components of these non-GAAP measures are computed by using amounts that are determined in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Reconciliations of non-GAAP measures to the most comparable GAAP measures are provided in the Appendix at the end of this presentation.

Adjusted EBITDA is a non-GAAP financial measure and should not be used in isolation or as a substitute for the amounts reported in accordance with GAAP. In addition, adjusted EBITDA excludes certain cash expenses that the Company is obligated to make. However, management evaluates the performance of its operating segments and the consolidated Company based on several criteria, including adjusted EBITDA and adjusted operating income (loss), because it believes that these financial measures accurately reflect the Company’s ongoing profitability and performance. Securities analysts and investors use this measure as one of the metrics on which they analyze the Company’s performance. Other companies in this industry may compute these measures differently. A reconciliation of this non-GAAP measure to net income (loss), which is the most closely comparable GAAP measure, is provided in the table below.

This non-GAAP measure has limitations and therefore should not be used in isolation or as a substitute for the amounts reported in accordance with GAAP. However, management evaluates the performance of its operating segments and the consolidated Company based on several criteria, including net debt, because it believes that this financial measure accurately measures the Company’s liquidity. In addition, securities analysts and investors use this measure as one of the metrics on which they analyze the company’s performance. Other companies in this industry may compute this measure differently. A reconciliation of net debt to total debt, which is the nearest comparable GAAP financial measure, is provided in the table below.

N A B O R S . C O M Three Months Ended March 31 2024 Net cash provided by operating activities $107,239 Add: Capital expenditures, net of proceeds from sales of assets (99,125) Adjusted free cash flow $ 8,114 (In Thousands) Reconciliation of Adjusted Free Cash Flow to Net Cash Provided by Operating Activities 28 Adjusted free cash flow represents net cash provided by operating activities less cash used for capital expenditures, net of proceeds from sales of assets. Management believes that adjusted free cash flow is an important liquidity measure for the company and that it is useful to investors and management as a measure of the company’s ability to generate cash flow, after reinvesting in the company for future growth, that could be available for paying down debt or to return to shareholders through dividend payments or share repurchases. Adjusted free cash flow does not represent the residual cash flow available for discretionary expenditures. Adjusted free cash flow is a non-GAAP financial measure that should be considered in addition to, not as a substitute for or superior to, cash flow from operations reported in accordance with GAAP.
