Business Combination, Asset Acquisition, Transaction between Entities under Common Control, and Joint Venture Formation [Abstract] |
Mergers and Acquisitions | Note 2. Mergers and Acquisitions During the third quarter of 2025, the Corporation completed $2.4 billion in acquisitions consisting primarily of proved and unproved acreage in the Permian basin. One of the acquisitions was partially funded by restricted cash as it qualified as a like-kind exchange. We accounted for these acquisitions as business combinations and allocated substantially all of their fair values to "Property, plant and equipment" on the Consolidated Balance Sheet. We did not recognize any goodwill associated with the acquisitions. Consideration paid was reflected in the Condensed Consolidated Statement of Cash Flows mainly in the line item “Additions to property, plant, and equipment”. Pioneer Natural Resources Company On May 3, 2024, the Corporation acquired Pioneer Natural Resources Company ("Pioneer"), an independent oil and gas exploration and production company. In connection with the acquisition, we issued 545 million shares of ExxonMobil common stock having a fair value of $63 billion on the acquisition date, and assumed debt with a fair value of $5 billion. The transaction was accounted for as a business combination in accordance with ASC 805, which requires that assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. The following table summarizes the fair values of the assets acquired and liabilities assumed.
(billions of dollars) | Pioneer
Current assets (1) | 3 |
Other non-current assets | 1 |
Property, plant & equipment (2) | 84 |
Total identifiable assets acquired | 88 |
Current liabilities (1) | 3 |
Long-term debt (3) | 5 |
Deferred income tax liabilities (4) | 16 |
Other non-current liabilities | 2 |
Total liabilities assumed | 26 |
Net identifiable assets acquired | 62 |
Goodwill (5) | 1 |
Net assets | 63 |
(1) Current assets and current liabilities consist primarily of accounts receivable and payable, with their respective fair values approximating historical values given their short-term duration, expectation of insignificant bad debt expense, and our credit rating.
(2) Property, plant and equipment, of which a significant portion relates to crude oil and natural gas properties, was primarily valued using the income approach. Significant inputs and assumptions used in the income approach included estimates for commodity prices, future oil and gas production volumes, drilling and development costs, and risk-adjusted discount rates. Collectively, these inputs are level 3 inputs.
(3) Long-term debt was valued using market prices as of the acquisition date, which reflects the use of level 1 inputs.
(4) Deferred income taxes represent the tax effects of differences in the tax basis and acquisition date fair values of assets acquired and liabilities assumed.
(5) Goodwill was allocated to the Upstream segment.
Debt Assumed in the Merger The following table presents long-term debt assumed at closing:
(millions of dollars) | Par Value | Fair Value as of May 2, 2024
0.250% Convertible Senior Notes due May 2025 (1) | 450 |  | 1,327 |
1.125% Senior Notes due January 2026 | 750 |  | 699 |
5.100% Senior Notes due March 2026 | 1,100 |  | 1,096 |
7.200% Senior Notes due January 2028 | 241 |  | 252 |
4.125% Senior Notes due February 2028 | 138 |  | 130 |
1.900% Senior Notes due August 2030 | 1,100 |  | 914 |
2.150% Senior Notes due January 2031 | 1,000 |  | 832 |
(1) In June 2024, the Corporation redeemed in full all of the Convertible Senior Notes assumed from Pioneer for an amount consistent with the acquisition date fair value.
Actual and Pro Forma Impact of Merger The following table presents revenues and earnings included in the Consolidated Statement of Income for Pioneer since the acquisition date (May 3, 2024) through September 30, 2024:
(millions of dollars) | Three Months Ended September 30, 2024 | Nine Months Ended September 30, 2024
Sales and other operating revenues | 6,291 |  | 10,663 |
Net income (loss) attributable to ExxonMobil | 615 |  | 1,013 |
The following table presents unaudited pro forma information for the Corporation as if the merger with Pioneer had occurred at the beginning of January 1, 2023:
Unaudited (millions of dollars) | Three Months Ended September 30, 2024 | Nine Months Ended September 30, 2024
Sales and other operating revenues | 87,792 |  | 266,349 |
Net income (loss) attributable to ExxonMobil | 8,610 |  | 26,866 |
The historical financial information was adjusted to give effect to the pro forma events that were directly attributable to the merger and factually supportable. The unaudited pro forma consolidated results are not necessarily indicative of what the consolidated results of operations actually would have been had the merger been completed on January 1, 2023. In addition, the unaudited pro forma consolidated results reflect pro forma adjustments primarily related to conforming Pioneer's accounting policies to ExxonMobil, additional depreciation expense related to the fair value adjustment of the acquired property, plant and equipment, our capital structure, Pioneer's transaction-related costs, and applicable income tax impacts of the pro forma adjustments. Our transaction costs to effect the acquisition were immaterial.
