Item 3.02. Unregistered Sales of Equity Securities.

On February 14, 2025, Diamondback Energy, Inc. (the “Company”) and Diamondback E&P LLC (the “Purchaser”), a wholly owned subsidiary of the Company, entered into a definitive securities purchase agreement with Double Eagle IV Midco, LLC (the “Seller”), pursuant to which the Purchaser will acquire all of the issued and outstanding interests of DE Permian, LLC, a Texas limited liability company, DE IV Combo, LLC, a Delaware limited liability company, and DE IV Operating, LLC, a Texas limited liability company, each of which is a wholly owned subsidiary of Seller (the “Pending Acquisition”). Consideration for the Pending Acquisition consists of $3.0 billion in cash and approximately 6.9 million shares of the Company’s common stock, par value $0.01 per share (the “Shares”), subject to customary adjustments. The cash portion of this transaction is expected to be funded through a combination of cash on hand, borrowings under the Company’s credit facility and/or proceeds from term loans and senior notes offerings. The Shares will be issued in reliance upon the exemption from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), provided by Section 4(a)(2) of the Securities Act as sales by an issuer not involving any public offering. The Pending Acquisition is expected to close on April 1, 2025, subject to the satisfaction of customary closing conditions and regulatory approval.
