Item 9A. Controls and Procedures.

SLB has carried out an evaluation under the supervision and with the participation of SLB’s management, including the Chief Executive Officer (“CEO”) and the Chief Financial Officer (“CFO”), of the effectiveness of SLB’s “disclosure controls and procedures” (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on this evaluation, the CEO and the CFO have concluded that, as of the end of the period covered by this report, SLB’s disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in the reports that SLB files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. SLB’s disclosure controls and procedures include controls and procedures designed so that information required to be disclosed in reports filed or submitted under the Exchange Act is accumulated and communicated to its management, including the CEO and the CFO, as appropriate, to allow timely decisions regarding required disclosure. There has been no change in SLB’s internal control over financial reporting that occurred during the fourth quarter of 2024 that has materially affected, or is reasonably likely to materially affect, SLB’s internal control over financial reporting.
