2025 Acquisition

On September 15, 2025, a wholly-owned subsidiary of the Company entered into a definitive agreement to acquire certain developed and undeveloped oil and gas assets located in the Williston Basin from XTO Energy Inc. and affiliates (collectively, “XTO”), subsidiaries of Exxon Mobil Corporation, for total cash consideration of $550.0 million, subject to customary purchase price adjustments (the “2025 Williston Basin Acquisition”). The effective date of the 2025 Williston Basin Acquisition was September 1, 2025.

On October 31, 2025, the Company completed the 2025 Williston Basin Acquisition for total cash consideration of $542.2 million, including a cash deposit of $55.0 million to XTO upon execution of the purchase and sale agreement and $487.2 million paid to XTO at closing (including customary preliminary purchase price adjustments). The Company funded the 2025 Williston Basin Acquisition with proceeds from the issuance of the 2030 Senior Notes (defined in Note 10—Long-Term Debt) and cash on hand. The 2025 Williston Basin Acquisition was accounted for as a business combination and was recorded under the acquisition method of accounting in accordance with ASC 805. The post-acquisition operating results and pro forma revenue and earnings for the 2025 Williston Basin Acquisition were not material to the Company’s consolidated financial statements and have therefore not been presented.

The Company recorded the assets acquired and liabilities assumed in the 2025 Williston Basin Acquisition at their estimated fair value on October 31, 2025 of $542.2 million. The allocation of the fair value to the identifiable assets acquired and liabilities assumed resulted inno goodwill or bargain purchase gain being recognized. Determining the fair value of the assets and liabilities of the 2025 Williston Basin Acquisition required judgment and certain assumptions to be made. See Note 5—Fair Value Measurements for additional information.
