Explanatory Note

This Amendment No. 2 to Schedule 13D (the “Amendment”) relates to the shares of Class A Common Stock of the Issuer whose principal executive office is located at 1400 Woodloch Forest Drive, Suite 300, The Woodlands, Texas 77380. This Amendment amends the Schedule 13D (the “Original Schedule 13D”) filed with the Securities and Exchange Commission (the “SEC”) by certain of the Reporting Persons (as defined below) on January 19, 2021, as amended by Amendment No. 1 filed with the SEC on February 23, 2022 (“Amendment No. 1” and, as further amended, supplemented or restated hereby, the “Schedule 13D”), to report and reflect that David Habachy, a member of the Board of the Issuer appointed by the Reporting Persons, no longer serves as an employee of, and is no longer affiliated with, Warburg Pincus LLC (“Warburg”) or any other Reporting Person, and that the Reporting Persons no longer have the right to appoint one director to the Issuer’s Board. All capitalized terms contained herein but not otherwise defined shall have the meanings ascribed to such terms in the Original Schedule 13D or Amendment No. 1, as applicable. Except as specifically provided herein, this Amendment does not modify any of the information previously reported in the Schedule 13D.

Item 4. Purpose of Transaction.

Item 4 of the Schedule 13D is hereby amended and supplemented to add the following:

Effective July 28, 2022, Mr. Habachy ceased to be employed by Warburg and, as a result, he is no longer affiliated with the Reporting Persons. While Mr. Habachy will remain a director of the Issuer, he will no longer serve in such capacity as a representative of the Reporting Persons. Accordingly, the Reporting Persons no longer maintain Issuer Board representation and, effective July 28, 2022, have waived their Board designation rights provided under Section 3 of the A&R Voting Agreement.

A&R Voting Agreement

In connection with Mr. Habachy’s cessation of employment with Warburg, the Issuer, the Reporting Persons and EnCap Investments L.P. (“EnCap”) entered into an amendment (the “Voting Agreement Amendment”) to the A&R Voting Agreement, effective as of August 1, 2022. The Voting Agreement Amendment, among other things, removes the Reporting Persons’ right to appoint one director to the Issuer’s Board, as previously provided under Section 3 of the A&R Voting Agreement.

Post Oak Voting Agreement

On April 14, 2022, in connection with the purchase of 4,611,808 shares of Common Stock by Cypress Investments, LLC, a fund managed by Post Oak Energy Capital, LP (“Post Oak”), certain of the Reporting Persons entered into a Voting Agreement (the “Post Oak Voting Agreement”) with Post Oak, the Issuer and EnCap. Pursuant to the Post Oak Voting Agreement, Post Oak has the right to designate one nominee to be nominated by the Issuer at each applicable annual (or special) meeting of stockholders of the Issuer to serve as a director on the Issuer’s Board. The Post Oak Voting Agreement also obligates Post Oak, EnCap and the Reporting Persons party thereto to, among other things, vote all of their respective shares of Common Stock for the Board’s nominees for election as directors at any meeting of the Issuer’s shareholders. The Post Oak Voting Agreement will terminate upon the later to occur of: (a) the first date on which Post Oak and its affiliates collectively beneficially own less than 5.5% of the Issuer’s outstanding Common Stock, and (b) the one-year anniversary of the Post Oak Voting Agreement. The Post Oak Voting Agreement may be terminated earlier if Post Oak delivers written notice to each of the other parties terminating the Post Oak Voting Agreement in its entirety with respect to Post Oak.

Item 5. Interest in Securities of the Issuer.

(a) The percentages identified in Amendment No. 1 are hereby amended and restated by the responses to Items 13 on the cover pages of this Amendment for the Reporting Persons, which responses are incorporated herein by reference.

The penultimate and last paragraphs of Item 5 (a)—(b) of the Schedule 13D are hereby amended and restated to read as follows:


In addition, as discussed in Item 2 above, by virtue of the agreements made pursuant to the A&R Voting Agreement (as amended) and the Post Oak Voting Agreement, the Reporting Persons, Post Oak and EnCap may be deemed to constitute a group for purposes of Rule 13d-3 under the Securities and Exchange Act of 1934, as amended. In the aggregate, such group would beneficially own 80,652,827 shares of Class A Common Stock, representing 58.2% of the outstanding Class A Common Stock as of July 14, 2022 (calculated on the basis of an assumed combined total of 138,697,289 shares of Common Stock outstanding, consisting of (i) 104,435,648 shares of Class A Common Stock outstanding as of July 14, 2022 and (ii) 34,261,641 shares of Class B Common Stock, of which 33,956,524 shares are held by the EnCap entities, assuming that all of such shares of Class B Common Stock, along with an equivalent number of membership units of EEH, were exchanged for newly issued shares of Common Stock on a one-for-one basis).

The Reporting Persons expressly disclaim any beneficial ownership of shares of Common Stock beneficially owned by EnCap Investments L.P., Post Oak Energy Capital, LP and their respective affiliates and such shares are not the subject of this Schedule 13D.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

Item 6 of the Schedule 13D is hereby amended and restated to read as follows:

Item 4 of the Schedule 13D summarizes certain provisions of the Voting Agreement, Registration Rights Agreement, Lock-Up Agreement, A&R Voting Agreement, Chisholm Registration Rights Agreement, Chisholm Lock-Up Agreement, Escrow Agreement, the Post Oak Voting Agreement and the Voting Agreement Amendment and is incorporated herein by reference. A copy of each of these agreements is attached as an exhibit to the Schedule 13D and is incorporated herein by reference.

Except as set forth herein, none of the Reporting Persons nor any of the Related Persons has any contracts, arrangements, understandings or relationships (legal or otherwise) with any person with respect to any securities of the Issuer, including but not limited to any contracts, arrangements, understandings or relationships concerning the transfer or voting of such securities, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or losses, or the giving or withholding of proxies.

Item 7. Materials to be Filed as Exhibits.
