Controls & Procedures

Management has concluded that both the Corporation’s disclosure controls and procedures and its internal control over financial reporting (ICFR) were effective as of December 31, 2023.

Key Components:

Disclosure Controls Effectiveness: Management determined that these controls are effective in ensuring required information is accumulated and communicated for timely decision-making regarding disclosures, and that the information is recorded, processed, summarized, and reported within specified SEC time periods.
ICFR Effectiveness: Based on an evaluation using the COSO Integrated Framework (2013), management concluded that ICFR was effective. Denbury Inc., a wholly owned subsidiary acquired during 2023, was excluded from this assessment due to its immaterial financial impact.

Identified Issues and Changes:

Material Weaknesses/Significant Deficiencies: None were identified; controls were deemed effective.
Changes in Controls: There were no changes noted during the Corporation's last fiscal quarter that materially affected, or are reasonably likely to materially affect, ICFR.
Remediation/New Procedures: No remediation efforts for weaknesses or noteworthy new controls/procedures were introduced during the reporting period.

ITEM 9A. CONTROLS AND PROCEDURES

Management's Evaluation of Disclosure Controls and Procedures

As indicated in the certifications in Exhibit 31 of this report, the Corporation's Chief Executive Officer, Chief Financial Officer, and Principal Accounting Officer have evaluated the Corporation's disclosure controls and procedures as of December 31, 2023. Based on that evaluation, these officers have concluded that the Corporation's disclosure controls and procedures are effective in ensuring that information required to be disclosed by the Corporation in the reports that it files or submits under the Securities Exchange Act of 1934, as amended, is accumulated and communicated to them in a manner that allows for timely decisions regarding required disclosures and are effective in ensuring that such information is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms.

Management's Report on Internal Control Over Financial Reporting

Management, including the Corporation's Chief Executive Officer, Chief Financial Officer, and Principal Accounting Officer, is responsible for establishing and maintaining adequate internal control over the Corporation's financial reporting. Management conducted an evaluation of the effectiveness of internal control over financial reporting based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that Exxon Mobil Corporation's internal control over financial reporting was effective as of December 31, 2023.

The Corporation excluded Denbury Inc. from our assessment of internal control over financial reporting as of December 31, 2023, because it was acquired by the Corporation in a business combination during 2023. Total assets and total revenues of Denbury Inc., a wholly owned subsidiary, represent two percent and less than one percent, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2023.

PricewaterhouseCoopers LLP, an independent registered public accounting firm, audited the effectiveness of the Corporation's internal control over financial reporting as of December 31, 2023, as stated in their report included in the Financial Section of this report.

Changes in Internal Control Over Financial Reporting

There were no changes during the Corporation's last fiscal quarter that materially affected, or are reasonably likely to materially affect, the Corporation's internal control over financial reporting.
