Item 8.01 Other Events.

As previously disclosed, on October 10, 2023, Exxon Mobil Corporation, a New Jersey corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among the Company, Pioneer Natural Resources Company, a Delaware corporation (“Pioneer”), and SPQR, LLC, a Delaware limited liability company and a wholly owned subsidiary of the Company (“Merger Sub”). Upon the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into Pioneer (the “Merger”), with Pioneer surviving the Merger as a wholly owned subsidiary of the Company.

On December 4, 2023, the Company and Pioneer each received a request for additional information and documentary materials (a “Second Request”) from the Federal Trade Commission (“FTC”) in connection with the FTC’s review of the Merger. The effect of a Second Request is to extend the waiting period imposed by the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), until 30 days after each of the Company and Pioneer has substantially complied with the Second Request issued to it, unless that period is extended voluntarily by the parties or terminated sooner by the FTC. Completion of the Merger remains subject to the expiration or termination of the waiting period under the HSR Act and the satisfaction or waiver of the other closing conditions specified in the Merger Agreement.

The Company and Pioneer continue to work constructively with the FTC in its review of the Merger and continue to expect that the Merger will be completed in the first half of 2024, subject to the fulfillment of the closing conditions, including receipt of required regulatory approvals and approval of Pioneer’s stockholders.

Important Information about the Merger and Where to Find It

In connection with the Merger between the Company and Pioneer, the Company and Pioneer have filed and will file relevant materials with the Securities and Exchange Commission (the “SEC”). On November 21, 2023, the Company filed with the SEC a registration statement on Form S-4 (the “Form S-4”) to register the shares of the Company common stock to be issued in connection with the Merger. The Form S-4 includes a proxy statement of Pioneer that also constitutes a prospectus of the Company. The information in the Form S-4 is not complete and may be changed. After the Form S-4 is declared effective, a definitive proxy statement/prospectus will be mailed to stockholders of Pioneer. This communication is not a substitute for the Form S-4, proxy statement or prospectus or any other document that the Company or Pioneer (as applicable) has filed or may file with the SEC in connection with the Merger. BEFORE MAKING ANY VOTING OR INVESTMENT DECISION, INVESTORS AND SECURITY HOLDERS OF THE COMPANY AND PIONEER ARE URGED TO READ THE FORM S-4, THE PROXY STATEMENT/PROSPECTUS AND ANY OTHER RELEVANT DOCUMENTS THAT ARE FILED OR WILL BE FILED WITH THE SEC, AS WELL AS ANY AMENDMENTS OR SUPPLEMENTS TO THESE DOCUMENTS, CAREFULLY AND IN THEIR ENTIRETY WHEN THEY BECOME AVAILABLE BECAUSE THEY CONTAIN OR WILL CONTAIN IMPORTANT INFORMATION ABOUT THE MERGER AND RELATED MATTERS. Investors and security holders may obtain free copies of the Form S-4 and the proxy statement/prospectus, as well as other filings containing important information about the Company or Pioneer, without charge at the SEC’s Internet website (http://www.sec.gov). Copies of the documents filed with the SEC by the Company are and will be available free of charge on the Company’s internet website at www.exxonmobil.com under the tab “investors” and then under the tab “SEC Filings” or by contacting the Company’s Investor Relations Department at investor.relations@exxonmobil.com.

This communication is for informational purposes and is not intended to, and shall not, constitute an offer to sell or the solicitation of an offer to buy any securities or a solicitation of any vote or approval, nor shall there be any offer, solicitation or sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.

Forward-Looking Statements

This communication contains “forward-looking statements” within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. In this context, forward-looking statements often address future business and financial events, conditions, expectations, plans or ambitions, and often contain words such as “expect,” “anticipate,” “intend,” “plan,” “believe,” “seek,” “see,” “will,” “would,” “target,” similar expressions, and variations or negatives of these words, but not all forward-looking statements include such words. Forward-looking statements by their nature address matters that are, to different degrees, uncertain, such as statements about the consummation of the Merger and the anticipated benefits thereof. All such forward-looking statements are based upon current plans, estimates, expectations and ambitions that are subject to risks, uncertainties and assumptions, many of which are beyond the control of the Company and Pioneer, that could cause actual results to differ materially from those expressed in such forward-looking statements. Important risk factors that may cause such a difference include, but are not limited to: the completion of the Merger on anticipated terms and timing, or at all, including obtaining regulatory approvals that may be required on anticipated terms and Pioneer stockholder approval; anticipated tax treatment, unforeseen liabilities, future capital expenditures, revenues, expenses, earnings, synergies, economic performance, indebtedness, financial condition, losses, future prospects, business and management strategies for the management, expansion and growth of the combined company’s operations and other conditions to the completion of the Merger, including the possibility that any of the anticipated benefits of the Merger will not be realized or will not be realized within the expected time period; the ability of the Company and Pioneer to integrate the business successfully and to achieve anticipated synergies and value creation; potential litigation relating to the Merger that could be instituted against the Company, Pioneer or their respective directors; the risk that disruptions from the Merger will harm the Company’s or Pioneer’s business, including current plans and operations and that management’s time and attention will be diverted on transaction-related issues; potential adverse reactions or changes to business relationships resulting from the announcement or completion of the Merger; rating agency actions and the Company and Pioneer’s ability to access short- and long-term debt markets on a timely and affordable basis; legislative, regulatory and economic developments, including regulatory actions targeting public companies in the oil and gas industry and changes in local, national, or international laws, regulations, and policies affecting the Company and Pioneer including with respect to the environment; potential business uncertainty, including the outcome of commercial negotiations and changes to existing business relationships during the pendency of the Merger that could affect the Company’s and/or Pioneer’s financial performance and operating results; certain restrictions during the pendency of the Merger that may impact Pioneer’s ability to pursue certain business opportunities or strategic transactions or otherwise operate its business; acts of terrorism or outbreak of war, hostilities, civil unrest, attacks against the Company or Pioneer, and other political or security disturbances; dilution caused by the Company’s issuance of additional shares of its common stock in connection with the Merger; the possibility that the transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; changes in policy and consumer support for emission-reduction products and technology; the impacts of pandemics or other public health crises, including the effects of government responses on people and economies; global or regional changes in the supply and demand for oil, natural gas, petrochemicals, and feedstocks and other market or economic conditions that impact demand, prices and differentials, including reservoir performance; changes in technical or operating conditions, including unforeseen technical difficulties; those risks described in Item 1A of the Company’s Annual Report on Form 10-K, filed with the SEC on February 22, 2023, and subsequent reports on Forms 10-Q and 8-K, as well as under the heading “Factors Affecting Future Results” on the Investors page of the Company’s website at www.exxonmobil.com (information included on or accessible through the Company’s website is not incorporated by reference into this communication); those risks described in Item 1A of Pioneer’s Annual Report on Form 10-K, filed with the SEC on February 23, 2023, and subsequent reports on Forms 10-Q and 8-K; and those risks described in the registration statement on Form S-4 and accompanying prospectus available from the sources indicated above. References to resources or other quantities of oil or natural gas may include amounts that the Company or Pioneer believe will ultimately be produced, but that are not yet classified as “proved reserves” under SEC definitions.

These risks, as well as other risks associated with the Merger, are more fully discussed in the proxy statement/prospectus included in the registration statement on Form S-4 filed with the SEC in connection with the Merger. While the list of factors presented here and the list of factors presented in the registration statement on Form S-4 are considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. We caution you not to place undue reliance on any of these forward-looking statements as they are not guarantees of future performance or outcomes and that actual performance and outcomes, including, without limitation, our actual results of operations, financial condition and liquidity, and the development of new markets or market segments in which we operate, may differ materially from those made in or suggested by the forward-looking statements contained in this communication. Neither the Company nor Pioneer assumes any obligation to publicly provide revisions or updates to any forward-looking statements, whether as a result of new information, future developments or otherwise, should circumstances change, except as otherwise required by securities and other applicable laws. Neither future distribution of this communication nor the continued availability of this communication in archive form on the Company’s or Pioneer’s website should be deemed to constitute an update or re-affirmation of these statements as of any future date.

Actions needed to advance the Company’s 2030 and 2035 greenhouse gas emission-reductions plans are incorporated into its medium-term business plans, which are updated annually. The reference case for planning beyond 2030 is based on the Company’s Energy Outlook research and publication. The Outlook is reflective of the existing global policy environment, the Energy Outlook does not attempt to project the degree of required future policy and technology advancement and deployment for the world, or the Company, to meet net zero by 2050. As future policies and technology advancements emerge, they will be incorporated into the Outlook, and the Company’s business plans will be updated accordingly. Actual future results, including the achievement of net zero in Upstream Permian Basin unconventional operated assets by 2030/2035 and plans to lower methane emissions from operated assets, to increase water recycling in our combined Permian operations, and to feed hydrogen, ammonia, and carbon capture projects could vary depending on the ability to execute operational objectives on a timely and successful basis; policy support for emission-reduction products and technologies; changes in laws, regulations and international treaties regarding lower emission technologies and projects; government incentives; unforeseen technical or operational difficulties; the outcome of research efforts and future technology developments, including the ability to scale projects, technologies, and markets on a commercially competitive basis; changes in supply and demand and other market factors affecting future prices of oil, gas, and petrochemical products; the actions of competitors; and other factors discussed in this communication and in the additional forward looking statement disclaimer included above.

All references to production rates, project capacity, resource size, and acreage are on a gross basis, unless otherwise noted.
