The Reporting Persons reserve the right to acquire additional securities of the Issuer in the open market, in privately negotiated transactions (which may be with the Issuer or with third parties) or otherwise, to dispose of all or a portion of their holdings of securities of the Issuer or to change their intention with respect to any or all of the matters referred to in this Item 4.

In addition, the Reporting Persons at any time and from time to time, may acquire additional securities of the Issuer, or retain or sell all or a portion of the securities then held, in the open market or in privately negotiated transactions. In addition, the Reporting Persons or their designees to the Issuer’s board of directors may engage in discussions with management, the board of directors, and shareholders of the Issuer and other relevant parties or encourage such persons to consider or explore extraordinary corporate transactions, such as: a merger; sales or acquisitions of assets or businesses; changes to the capitalization or dividend policy of the Issuer; or other material changes to the Issuer’s business or corporate structure, including changes in management or the composition of the Issuer’s board of directors.

Except for the matters set forth in Items 3, 5 and the first paragraph of this Item 4, the Reporting Persons have no plans or proposals which relate to, or could result in, any of the matters referred to in paragraphs (a) through (j) inclusive of the instructions to Item 4 of Schedule 13D. The Reporting Persons may, at any time and from time to time, review or reconsider their position, change their purpose or formulate plans or proposals with respect thereto.

Item 5.

Interest in Securities of the Issuer.

The information below is based on an estimated total of 19,688,188 shares of Common Stock outstanding as of July 2, 2021, as reported by the Issuer on June 30, 2021.

(a) Each of the Reporting Persons (other than Yorktown X, Yorktown X Co, and Yorktown X Associates) beneficially owns an aggregate of 4,286,550 shares of Common Stock of the Issuer, representing 21.8% of the outstanding Common Stock of the Issuer. Yorktown X, Yorktown X Co, and Yorktown X Associates beneficially own 4,667,410 shares of Common Stock of the Issuer, representing 23.8% of the outstanding Common Stock of the Issuer. Each Reporting Person disclaims beneficial ownership of the reported Common Stock except to the extent of such Reporting Person’s pecuniary interest therein, and this statement shall not be deemed an admission that such Reporting Person is the beneficial owner of the reported Common Stock for the purposes of Section 13(d) of the Exchange Act or any other purpose.

(b) REXG directly owns 4,286,550 shares of Common Stock of the Issuer. Yorktown X directly owns 390,860 shares of Common Stock of the Issuer. Yorktown IV, Yorktown V, Yorktown VI, Yorktown VII, Yorktown VIII, Yorktown IX, and Yorktown X (collectively, “Yorktown”) collectively own approximately 94% of REXG. Pursuant to the terms of the Amended and Restated Limited Liability Agreement of REXG (“REXG LLC Agreement”), Yorktown has the ability to elect a majority of the Board of Managers of REXG. Because Yorktown IV Co is the sole general partner of Yorktown IV, it may be deemed to beneficially own shares of the Issuer based on its relationship with Yorktown IV. Yorktown IV and Yorktown IV Co disclaim beneficial ownership of the Issuer’s shares owned by REXG except to the extent of their pecuniary interest therein. Because Yorktown V Co is the sole general partner of Yorktown V, it may be deemed to beneficially own shares of the Issuer based on its relationship with Yorktown V. Yorktown V and Yorktown V Co disclaim beneficial ownership of the Issuer’s shares owned by REXG except to the extent of their pecuniary interest therein. Because Yorktown VI Associates is the sole general partner of Yorktown VI Co, the sole general partner of Yorktown VI, it may be deemed to beneficially own shares of the Issuer based on its relationship with Yorktown VI. Yorktown VI, Yorktown VI Co and Yorktown VI Associates disclaim beneficial ownership of the shares owned by REXG except to the extent of their pecuniary interest therein. Because Yorktown VII Associates is the sole general partner of Yorktown VII Co, the sole general partner of Yorktown VII, it may be deemed to beneficially own shares of the Issuer based on its relationship with Yorktown VII. Yorktown VII, Yorktown VII Co and Yorktown VII Associates disclaim beneficial ownership of the shares owned by REXG except to the extent of their pecuniary interest therein. Because Yorktown VIII Associates is the sole general partner of Yorktown VIII Co, the sole general partner of Yorktown VIII, it may be deemed to beneficially own shares of the Issuer based on its relationship with Yorktown VIII. Yorktown VIII, Yorktown VIII Co and Yorktown VIII Associates disclaim beneficial ownership of the shares owned by REXG except to the extent of their pecuniary interest therein. Because Yorktown IX Associates is the sole general partner of Yorktown IX Co, the sole general partner of Yorktown IX, it may be deemed to beneficially own shares of the Issuer based on its relationship with Yorktown IX. Yorktown IX, Yorktown IX Co and Yorktown IX Associates disclaim beneficial ownership of the shares owned by REXG except to the extent of their pecuniary interest therein. Because Yorktown X Associates is the sole general partner of Yorktown X Co, the sole general partner of Yorktown X, it may be deemed to beneficially own shares of the Issuer based on its relationship with Yorktown X.

(c) Except as otherwise described herein or in any exhibit filed hereunder, none of the Reporting Persons has effected any transaction in the Common Stock during the past 60 days.

(d) Except as otherwise described herein, no person other than the Reporting Persons has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the shares of Common Stock reported on this Schedule 13D.

(e) Not applicable.

Item 6.

Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

The information provided or incorporated by reference in Item 3 and Item 4 is hereby incorporated by reference herein.

Registration Rights Agreement

Prior to the closing of the Merger, REXG entered into a second amended and restated registration rights agreement (the “Registration Rights Agreement”) with Yorktown Energy Partners XI, L.P., REP, Bluescape Riley Exploration Holdings LLC (“Bluescape”), Boomer Petroleum, LLC (“Boomer”), Bobby Riley, Kevin Riley and Corey Riley. The Registration Rights Agreement provides for customary rights for these parties to demand that REP (or certain successors by merger, which would include the Issuer) file a resale shelf registration statement and certain piggyback rights with respect to registrable securities held by such parties (which registrable securities would include the Common Stock received pursuant to the Merger). Pursuant to the terms of the Registration Rights Agreement, 16,238,131 shares of the Issuer’s Common Stock are registrable under the Registration Rights Agreement following the closing of the Merger. In addition, the Registration Rights Agreement grants these parties customary rights to participate in certain underwritten offerings of the Issuer’s Common Stock that the Issuer may conduct.

Subject to certain limitations described below, REP has agreed no later than 60 days following the Merger to prepare and file a registration statement registering the offer and sale of their registrable securities. Subject to certain limitations in the Registration Rights Agreement, parties to the Registration Rights Agreement holding more than 15% of the then-currently registrable securities under the Registration Rights Agreement can require REP to participate in a firm underwritten resale of the securities; provided that the combined company will not be obligated to participate in more than two such underwritten resales per year.

Subject to certain exceptions, if at any time the combined company proposes to register an offering of equity securities or conduct an underwritten offering, whether or not for its own account, then the combined company must notify the equity holders party to the Registration Rights Agreement of such proposal to allow them to include a specified number of their registrable securities in that registration statement or underwritten offering, as applicable.

These registration rights are subject to certain conditions and limitations, including the right of the underwriters to limit the number of shares to be included in a registration and the combined company’s right to suspend use of a prospectus under a registration statement under certain circumstances, including if the combined company is pursuing a bona fide material acquisition, merger, reorganization, disposition or other similar transaction and the combined company’s board of managers determines in good faith that the combined company’s ability to pursue or consummate such a transaction would be materially and adversely affected by any required disclosure of such transaction in the registration statement (and such disclosure is then-required therein by applicable law, rule or regulation to permit offers and sales thereunder), the combined company has experienced some other material non-public event the disclosure of which in the registration statement at such time, in the good faith judgment of the combined company’s board, would materially and adversely affect the combined company (and such disclosure therein is then-required by applicable law, rule or regulation to permit offers and sales thereunder), or the combined company’s board shall have determined in good faith, upon the advice of counsel, that it is required by law, rule or regulation to file a post-effective amendment to such registration statement to reflect certain updated information of the type described in the Registration Rights Agreement. The Registration Rights Agreement provides certain time limitations on how long such delays may be implemented. The combined company will generally pay all registration expenses in connection with its obligations under the Registration Rights Agreement, regardless of whether a registration statement is filed or becomes effective.

The foregoing description of the Registration Rights Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Registration Rights Agreement filed as Exhibit 4.1 to Amendment No. 1 to the Issuer’s Registration Statement on Form S-4 filed with the Securities and Exchange Commission on December 31, 2020, and incorporated herein by reference.

First Amended and Restated Certificate of Incorporation of Riley Exploration Permian, Inc.

In connection with the closing of the Merger, the stockholder’s of the Issuer approved the First Amended and Restated Certificate of Incorporation of the Issuer (the “Charter”). Pursuant to the terms of the Charter, prior to the first date on which investment funds sponsored or managed by Yorktown Partners LLC, Boomer and Bluescape (or their affiliated investment funds, including, without limitation, the Reporting Persons) no longer individually or collectively beneficially own (or otherwise have the right to vote or direct the vote of) more than 50% of the outstanding shares of Issuer’s Common Stock (the “Trigger Date”), the affirmative vote of the holders of a majority in voting power of the outstanding shares of stock of the Issuer entitled to vote thereon, voting together as a single class and acting at a meeting of the stockholders or by written consent (if permitted) in accordance with the DGCL, the Charter and the Bylaws, shall be required to amend, alter or repeal any provision of the Charter. On and after the Trigger Date, the affirmative vote of the holders of at least 66 2/3% in voting power of the outstanding shares of stock of the Issuer entitled to vote thereon, voting together as a single class, shall be required to amend, alter or repeal any provision of the Charter; provided, however, that the amendment, alteration or repeal of Section 4 of the Charter shall only require the affirmative vote of the holders of a majority in voting power of the outstanding shares of stock of the Issuer entitled to vote thereon, voting together as a single class.

The foregoing description of the Charter does not purport to be complete and is qualified in its entirety by reference to the full text of the First Amended and Restated Certificate of Incorporation of the Issuer filed as Exhibit 4.1 to the Issuer’s Registration Statement on Form S-8 filed with the Securities and Exchange Commission on March 1, 2021, Registration No. 333-253750, and incorporated herein by reference.

Second Amended and Restated Bylaws of Riley Exploration Permian, Inc.

In connection with the closing of the Merger, the stockholder’s of the Issuer approved the Second Amended and Restated Bylaws of the Issuer (the “Bylaws”). Pursuant to the terms of the Bylaws, the Issuer’s stockholders shall also, in add ition to the Issuer’s board of directors, have the power to adopt, amend or repeal the Bylaws without any requirement to obtain separate board of directors approval; provided, however, that, in addition to any vote of the holders of any class or series of stock of the Issuer required by law or by the Charter, the Bylaws may be adopted, altered, amended or repealed by the stockholders of the Issuer only (A) prior to the Trigger Date, by the affirmative vote of holders of not less than 50% in voting power of the then-outstanding shares of stock entitled to vote thereon, voting together as a single class, or (B) on and after the Trigger Date, by the affirmative vote of holders of not less than 66 2/3% in voting power of the then-outstanding shares of stock entitled to vote thereon, voting together as a single class.

The foregoing description of the Bylaws does not purport to be complete and is qualified in its entirety by reference to the full text of the Second Amended and Restated Bylaws of the Issuer filed as Exhibit 4.2 to the Issuer’s Registration Statement on Form S-8 filed with the Securities and Exchange Commission on March 1, 2021, Registration No. 333-253750 and incorporated herein by reference.

Lock-up Agreements

In connection with a public offering of Common Stock by the Issuer, on June 30, 2021, REXG entered into a Lock-Up Agreement with Truist Securities, Inc. (“Truist”) pursuant to which, without the prior written consent of Truist, REXG agreed it will not directly or indirectly, (1) offer for sale, sell, issue, contract to sell, pledge or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any shares of the Common Stock or other securities or securities convertible into or exchangeable for the Common Stock or other securities, (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of such shares of the Common Stock or other securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise, (3) requested and market conditions at the time securities or securities convertible, exercisable or exchangeable into the Common Stock or other securities, (4) file or cause to be filed a registration statement, including any amendments, with respect to the registration of any shares of the Common Stock or other securities or securities convertible, exercisable or exchangeable into Common Stock or other securities, (5) establish or increase a put equivalent position or liquidate or decrease a call equivalent position in securities of the Issuer or (6) publicly disclose the intention to do any of the foregoing for a period of 60 days.
