Introductory Note

This Amendment No. 4 (this “Amendment”) amends and supplements the Schedule 13D filed with the Securities and Exchange Commission on May 8, 2017 (the “Original Schedule 13D”), as amended by Amendment No. 1 to Schedule 13D, filed on November 13, 2017 ( the “First Amendment”), Amendment No. 2 to Schedule 13D, filed on January 23, 2018 (the “Second Amendment”), and Amendment No. 3 to Schedule 13D, filed on October 2, 2018 (the “Third Amendment”). The purpose of this Amendment is to update the percentage ownership of the Reporting Persons as a result of the exercise of the underwriters’ over-allotment option to purchase 840,744 shares of Class A Common Stock in connection with an underwritten public offering by Rosehill Resources Inc., a Delaware corporation (the “Issuer” or the “Company”), which closed on October 10, 2018.

This Amendment amends the cover pages (as set forth in the foregoing pages), Item 5 and Schedule A of the Original Schedule 13D, as amended by the First Amendment, the Second Amendment and the Third Amendment (as set forth below). Capitalized terms used herein and not otherwise defined have the meaning assigned to such terms in the Original Schedule 13D. All items or responses not described herein remain as previously reported in the Original Schedule 13D, as amended by the First Amendment, the Second Amendment and the Third Amendment.

Item 5.

Interest in Securities of the Issuer

(a) and (b) The responses of the Reporting Persons to rows 7, 8, 9, 10, 11 and 13 on the cover pages of this Amendment are incorporated herein by reference.

RHoldings is the record owner of 59 shares of Series A Preferred Stock, which may initially be converted into 5,131 shares of Class A Common Stock in accordance with the terms of the Certificate of Designations. Tema is the record owner of (i) 29,807,692 shares of Class B Common Stock, which, together with the Rosehill Operating Common Units, are exchangeable for shares of Class A Common Stock of the Issuer on a one-for-one basis at any time, subject to the terms of the A&R LLC Agreement, (ii) 4,750,000 warrants, entitling the holder thereof to purchase one share of Class A Common Stock at an exercise price of $11.50 per share, and (iii) 19,166 shares of Series A Preferred Stock, which may initially be converted into 1,666,609 shares of Class A Common Stock in accordance with the terms of the Certificate of Designations. Tema and RHoldings are each direct, wholly-owned subsidiaries of Rosemore.

Edward Kovalik is the record owner of 36,671 shares of Class A Common Stock.

Sponsor is the record owner of (i) 926,020 shares of Class A Common Stock and (ii) 7 shares of Series A Preferred Stock, which may initially be converted into 609 shares of Class A Common Stock in accordance with the terms of the Certificate of Designations. KLR Investments is the managing member of Sponsor. Mr. Kovalik is the Chief Executive Officer and Managing Partner of KLR Group, LLC and the managing member of KLR Group Holdings, LLC (“KLR Holdings”) which owns 100% of KLR Investments.

Because of the relationship between Sponsor and Tema as a result of the SHRRA, each Reporting Person may be deemed to beneficially own 39,814,924 shares of Class A Common Stock. Each Reporting Person disclaims beneficial ownership of the shares except to the extent of its pecuniary interest therein.

The aggregate percent of Class A Common Stock beneficially owned by the Reporting Persons is based on 51,970,744 shares of Class A Common Stock deemed to be outstanding, including (i) 13,533,112 shares of Class A Common Stock currently issued and outstanding, (ii) 5,131 shares of Class A Common Stock issuable upon conversion of Series A Preferred Stock held by RHoldings, (iii) 29,807,692 shares of Class A Common Stock issuable upon conversion of shares of Class B Common Stock held by Tema, (iv) 4,750,000 shares of Class A Common Stock issuable upon exercise of warrants owned by Tema, (v) 1,666,609 shares of Class A Common Stock issuable upon conversion of Series A Preferred Stock held by Tema, (vi) 2,118,547 shares of Class A Common Stock issuable upon exercise of warrants owned by KLR Investments, (vii) 89,044 shares of Class A Common Stock issuable upon conversion of shares of Series A Preferred Stock owned by KLR Investments, and (viii) 609 shares of Class A Common Stock issuable upon conversion of shares of Series A Preferred Stock owned by Sponsor.

To the knowledge of the Reporting Persons, the executive officers and directors of Rosemore, Tema and RHoldings have no beneficial ownership of Class A Common Stock other than (i) 36,671 shares of Class A Common Stock owned by Frank Rosenberg (comprising less than one percent (0.3%) of the shares of the outstanding Class A Common Stock), (ii) 36,671 shares of Class A Common Stock owned by William E. Mayer (comprising less than one percent (0.3%) of the shares of the outstanding Class A Common Stock), (iii) 300 shares of Class A Common Stock and 300 additional shares of Class A Common Stock issuable upon conversion of warrants owned by Robert A. Delp (together comprising less than one percent (0.005%) of the shares of the outstanding Class A Common Stock), (iv) 2,500 shares of Class A Common Stock issuable upon conversion of warrants owned by Paul Ebner (comprising less than one percent (0.02%) of the shares of the outstanding Class A Common Stock), and (v) 1,000 shares of Class A Common Stock issuable upon conversion of warrants owned by Henry A. Rosenberg, Jr. (comprising less than one percent (0.008%) of the shares of the outstanding Class A Common Stock).

To the knowledge of the Reporting Persons, the manager or executive officers of Sponsor, KLR Holdings and KLR Investments have no beneficial ownership of Class A Common Stock other than Kovalik and Gregory R. Dow, who respectively own 36,671 and 40,000 shares of Class A Common Stock.

(c) Since the date of filing of the Third Amendment, the directors and executive officers of Rosemore, Tema and RHoldings have not engaged in any transactions in the Issuer’s securities.
