Acquisitions and Divestitures

Grayson Mill Acquisition

On September 27, 2024, Devon completed its acquisition of the Williston Basin business of Grayson Mill for total consideration of approximately $5.0 billion, consisting of $3.5 billion of cash and approximately 37.3 million shares of Devon common stock, including purchase price adjustments. Devon funded the cash portion of the purchase price through cash on hand and debt financing. For additional information regarding the debt financing, see Note 13.

Purchase Price Allocation

This transaction was accounted for using the acquisition method of accounting. Under the acquisition method of accounting, the assets and liabilities of Grayson Mill and its subsidiaries were recorded at their respective fair values as of the date of completion of the acquisition and added to Devon’s. Determining the fair value of the assets and liabilities of Grayson Mill required judgment and certain assumptions to be made, the most significant of these being related to the valuation of Grayson Mill’s oil and gas properties. The inputs and assumptions related to the oil and gas properties were categorized as level 3 in the fair value hierarchy.

The following table represents the final allocation of the total purchase price of Grayson Mill to the identifiable assets acquired and the liabilities assumed based on the fair values as of the acquisition date.

Asset Exchange

On April 1, 2025, Devon and BPX Energy dissolved their partnership and divided their acreage in the Eagle Ford Blackhawk field located in Texas' DeWitt County, resulting in increased operational flexibility for both parties. The assets exchanged were in close proximity and shared similar geological characteristics. The transaction was accounted for as an equal, non-monetary exchange, as it did not result in a significant change to the risks, expected future cash flows or the timing of those cash flows, and therefore was

determined to lack commercial substance. As a result, the new acreage and underlying property costs were recorded at the historical cost of the assets exchanged.

Divestiture of Matterhorn Investment

During the second quarter of 2025, Devon sold its investment in Matterhorn for $372 million and recognized a pre-tax gain of $307 million ($239 million, net of tax), which was recorded to asset dispositions on the accompanying consolidated statements of comprehensive earnings. For additional information, see Note 12.

Contingent Earnout Payments

Devon was entitled to contingent earnout payments associated with the sale of its Barnett Shale assets in 2020 with upside participation beginning at a $2.75 Henry Hub natural gas price or a $50 WTI oil price. The contingent payment period commenced on January 1, 2021, and had a term of four years. Devon received $20 million in contingent earnout payments related to this transaction in the first nine months of both 2025 and 2024.
