NABORS INDUSTRIES LTD

Disclosure Controls and Procedures

We maintain a set of disclosure controls and procedures (as such term is defined in Rule 15d-15(e) under the Exchange Act) designed to provide reasonable assurance that information required to be disclosed in our reports filed or submitted 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 annual report. Based on this evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that, as of December 31, 2025, the Company’s disclosure controls and procedures were effective at the reasonable assurance level.

Management’s Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. GAAP. Our internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. GAAP, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the financial statements.

Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper management override. Because of these limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk.

Management conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting based on the criteria set forth in theInternal Control—Integrated Framework issued in 2013 by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this evaluation, management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2025.

The foregoing assessment excludes certain entities of Parker from our assessment of internal control over financial reporting as of December 31, 2025. The Company acquired Parker in a business combination on March 11, 2025. In August 2025, the Company sold Quail Tools LLC which was part of the company’s acquisition of Parker. After the acquisition, certain of the remaining entities of Parker were integrated into the Company’s existing systems and internal control over financial reporting. The entities that were not integrated have been excluded from our assessment of the effectiveness of internal control over financial reporting as of December 31, 2025. The exclusion represents controls covering approximately 2% of consolidated assets and approximately 10% of consolidated revenues (which includes the

approximately 5 months of revenue related to Quail Tools LLC prior to disposition, as it was not integrated prior to its’ sale). This exclusion is in accordance with the general guidance issued by the Staff of the SEC that an assessment of a recent business acquisition may be omitted from management’s report on internal control over financial reporting on the first year of consolidation.

PricewaterhouseCoopers LLP has issued a report on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2025, which is included in Part II, Item 8 of this annual report.
