As previously disclosed, on December 18, 2020, Diamondback Energy, Inc. (the “Company”) and Diamondback E&P LLC, a wholly-owned subsidiary of the Company, entered into a definitive purchase and sale agreement (the “Purchase Agreement”) with Guidon Operating LLC (“Guidon”) and certain of Guidon’s affiliates to acquire approximately 32,500 net acres in the Northern Midland Basin and certain related oil and gas assets (the “Guidon Acquisition”) for $375 million in cash and 10.63 million shares of the Company’s common stock, par value $0.01 per share, subject to adjustment. This Amendment No. 1 to the Current Report on Form 8-K amends Item 3.02 of the Current Report on Form 8-K originally filed by the Company on December 21, 2020 solely to include disclosure on the number of shares of common stock of the Company actually issued pursuant to the Purchase Agreement.

Item 3.02. Unregistered Sales of Equity Securities.

The Shares were 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.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
