Diversified Energy Company

Item 1.01 Entry into a Material Definitive Agreement On September 2, 2026, Diversified Energy Company (the “Company”) entered into definitive agreements to acquire Birch Permian Holdings, Inc. and certain affiliated companies. On such date, the Company and DEC Merger Sub, Inc., a wholly owned subsidiary of the Company (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Birch Permian Holdings, Inc. (“BPHI”) pursuant to which Merger Sub agreed to merge with and into BPHI (the “Merger”). Concurrently with the execution of the Merger Agreement, the Company entered into a Purchase Agreement (the “MIP Purchase Agreement”) with holders of non-voting incentive interests in Birch Permian, LLC, a subsidiary of BPHI (“Birch Permian”), pursuant to which the Company will acquire all of the outstanding non-voting incentive interests in Birch Permian (the “MIP Interest Acquisition”), as well as a Membership Interests Purchase Agreement (the “Birch II Purchase Agreement,” and together with the Merger Agreement and the MIP Purchase Agreement, the “Transaction Agreements”) with Birch Permian II, LLC (“Birch II”), pursuant to which the Company will acquire from Birch II all of the equity interests in Milkwater, LLC and Birch II EOC, LLC, each a wholly owned subsidiary of Birch II (the “Birch II Acquisition,” and together with the Merger and the MIP Interest Acquisition, the “Transactions”). Pursuant to the Transactions, the Company will acquire approximately 46,000 net mineral acres in the Midland Basin, including 500 gross operated (480 net total) wells, as well as integrated midstream and water infrastructure assets. The aggregate purchase price for the Transactions is approximately $1.8 billion (inclusive of repayment of indebtedness), subject to adjustments in the Transaction Agreements, and is expected to be funded by an asset-backed securitization of approximately $1.5 billion in advance of closing, along with customary financing sources including the available liquidity under the Company’s revolving credit facility. The Transactions are expected to close simultaneously in the fourth quarter of 2026, subject to the satisfaction of customary closing conditions. Merger Agreement The Merger Agreement contains customary representations, warranties and covenants by the parties. The obligations of the Company and BPHI to consummate the Merger are subject to customary closing conditions. The Merger Agreement may be terminated prior to closing under certain circumstances, including by mutual agreement of the parties, by either party if closing has not occurred by a specified outside date (subject to automatic extension in certain circumstances related to the HSR waiting period), by either party upon entry of a final non-appealable order or adoption of any law or other action permanently prohibiting the consummation of the Merger, or by either party upon an uncured material breach by the other party. The Merger Agreement provides for a deposit of $50 million to be delivered concurrently with the execution thereof, and for a purchase price of approximately $1.1 billion (inclusive of repayment of indebtedness) to be delivered at closing, determined net of the deposit amount and subject to certain adjustments as of closing. In the event the Merger Agreement is terminated by BPHI when BPHI is not in material breach of the Merger Agreement and all conditions to the Company’s obligation to close have been satisfied or waived, and closing has failed to occur as a result of the Company’s material breach or failure to perform its obligations under the Merger Agreement, BPHI will be entitled to payment of a termination fee of $50 million and to retain the deposit for its own account. MIP Purchase Agreement The MIP Purchase Agreement contains customary representations, warranties and covenants by the parties. The obligations of the Company and of the sellers under the MIP Purchase Agreement to consummate the MIP Interest Acquisition are subject to the prior or substantially contemporaneous consummation of the Merger and of the Birch II Acquisition, and to customary closing conditions. The MIP Purchase Agreement provides for a purchase price of approximately $281 million (inclusive of repayment of indebtedness) to be delivered at closing, subject to certain adjustments as of closing. The MIP Purchase Agreement will automatically terminate in the event of a termination of the Merger Agreement in accordance with the terms thereof. Birch II Purchase Agreement The Birch II Purchase Agreement contains customary representations, warranties and covenants by the parties. The obligations of the Company and of the sellers under the Birch II Purchase Agreement to consummate the Birch II Acquisition are subject to the prior or substantially contemporaneous consummation of the Merger and of the MIP Acquisition, and to customary closing conditions. The Birch II Purchase Agreement provides for a purchase price of approximately $413 million to be delivered at closing, subject to certain adjustments as of closing. The Birch II Purchase Agreement will automatically terminate in the event of a termination of the Merger Agreement in accordance with the terms thereof. The foregoing descriptions of the Merger Agreement, the MIP Purchase Agreement, and the Birch II Purchase Agreement do not purport to be complete and are qualified in their entirety by reference to the full text of the Merger Agreement, the MIP Purchase Agreement, and the Birch II Purchase Agreement, which are filed as Exhibits 2.1, 2.2, and 2.3 hereto, respectively, and are incorporated herein by reference.
