SCHEDULE 13D A/6

This Amendment No. 6 to Schedule 13D (the "Amendment No. 6") modifies and supplements the Schedule 13D initially filed on October 22, 2012, as amended by Amendment No. 1 filed on December 11, 2012,  Amendment No. 2 filed on July 2, 2013, Amendment No. 3 filed on November 18, 2013, Amendment No. 4 filed on March 4, 2014 and Amendment No. 5 filed on March 26, 2014  (the "Statement"), with respect to the common stock, $0.01 par value per share (the “Common Stock”), of Diamondback Energy, Inc. (the “Issuer”). Except to the extent supplemented or amended by the information contained in this Amendment No. 6, the Statement remains in full force and effect.  Capitalized terms used herein without definition have the respective meanings ascribed to them in the Statement.

Item 4.                                Purpose of the Transaction
 
Item 4 is hereby amended to add the following:

The Funds entered into that certain Underwriting Agreement with Credit Suisse Securities (USA) LLC (the “Underwriter”), the Issuer and Gulfport Energy Corporation (the “Underwriting Agreement”), providing for an underwritten public offering of shares of Common Stock by the Funds and Gulfport Energy Corporation.  Pursuant to the Underwriting Agreement, DB Holdings, WSF, WCF, SIF and CIF agreed to sell to the Underwriter, and the Underwriter agreed to buy, 942,794, 11,248, 1,778, 37,208 and 6,972 shares of Common Stock, respectively (the “Firm Offering”), under the Issuer’s effective registration statement on Form-3 (File No. 333-192009) including a base prospectus, filed with the Securities and Exchange Commission (the “Commission”) which became effective immediately upon filing with the Commission on November 5, 2013 and a preliminary prospectus supplement dated June 23, 2014 and a prospectus supplement dated June 24, 2014, the pricing date, as filed with the Commission pursuant to Rule 424(b)(5) under the Securities Act.  The Underwriter was also granted a 30-day option to purchase up to an additional 141,419, 1,687, 267, 5,581 and 1,046 shares of Common Stock from DB Holdings, WSF, WCF, SIF and CIF, respectively (the “Optional Offering” and, together with the Firm Offering, the “Offering”). The purchase price paid by the Underwriter to the Funds for the shares sold in the Firm Offering was $89.12 per share after underwriting discounts and commissions. The Firm Offering closed on June 27, 2014.

In connection with its entry into the Underwriting Agreement, each of the Funds entered into a Lock-Up Agreement on June 24, 2014 (collectively, the “Lock Up Agreements”), pursuant to which each Fund agreed that, subject to certain exceptions, it will not offer, sell, contract to sell, pledge, or otherwise dispose of, directly or indirectly, any shares of Common Stock or securities convertible into or exchangeable or exercisable for any shares of Common Stock, enter into a transaction that would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of Common Stock, whether any of these transactions are to be settled by delivery of Common Stock or other securities, in cash or otherwise, or publicly disclose the intention to make any offer, sale, pledge or disposition, or to enter into any transaction, swap, hedge or other arrangement, without in each case, the prior written consent of the Underwriter for a period of 30 days after the date of the final prospectus for the Offering.  Subject to the restrictions on transfers set forth in the Lock-Up Agreements discussed above, the Funds may sell additional shares of Common Stock in the future, but have no present plans to do so except for the sale of shares in the Optional Offering to the extent the Underwriter exercises its option to purchase such shares.
