Item 4. Purpose of the Transaction.

Item 4 of the Schedule 13D is hereby amended by inserting the following information at the end of Item 4:

The Drop Merger

On October 14, 2021, the Issuer entered into an agreement and plan of merger (the “Drop Merger Agreement”) by and among the Issuer, Enviva Holdings, LP (“Holdings”), Enviva Partners Merger Sub, LLC, and the limited partners of Holdings set forth in the Drop Merger Agreement (including the Riverstone Echo Funds, the “Holdings Limited Partners”). Pursuant to the terms of the Drop Merger Agreement, (a) the Issuer acquired (i) all of the limited partner interests in Holdings and (ii) all of the limited liability company interests in Enviva Holdings GP, LLC (“Holdings GP”) and (b) the incentive distribution rights directly held by Enviva MLP Holdco, LLC (“MLP Holdco”), were cancelled and eliminated (collectively, the “Drop Merger”). In consideration for the Drop Merger, the Issuer issued 14,104,100 Common Units to the Riverstone Echo Funds. The Drop Merger closed on October 14, 2021.

In connection with the Drop Merger, MLP Holdco distributed all of its Common Units to Holdings, which then distributed its directly owned Common Units and Acquisition I to the Riverstone Echo Funds.

Also in connection with the Drop Merger, the Riverstone Echo Funds entered into the Acquisition I Merger Agreement (as defined below), the Support Agreement (as defined below), the Registration Rights Agreement (as defined below), and the Stockholders Agreement (as defined below).

The Conversion and the Support Agreement

In connection with the Drop Merger, the Issuer entered into a support agreement (the “Support Agreement”) by and among the Issuer, the Holdings Limited Partners party thereto and certain other persons thereto pursuant to which, among other things:

(a) certain of Holdings’ (or its subsidiaries) obligations to provide financial support to the Issuer were consolidated, fixed and novated into fixed payment amounts (the “Support Payments”) to be paid solely out of distributions or dividends on certain Common Units held by certain Holdings Limited Partners, and in the event the Support Payment for a payment date exceeds the distributions or dividends received during the calendar quarter applicable to such payment date, then such excess will be added to such Holdings Limited Partners’ Support Payment for the immediately following payment date until the shortfall in the Support Payments is reduced to zero;

(b) each Holdings Limited Partner party thereto agreed to reinvest all regular quarterly distributions or dividends in respect of a portion of the Common Units issued to such Holdings Limited Partner in the Drop Merger, for each calendar quarter from the calendar quarter ending September 30, 2021, through and including the calendar quarter ending December 31, 2024; and

16

CUSIP No. 29414J107 13D Page 17 of 22 Pages

(c) each Holdings Limited Partner party thereto agreed, subject to certain exceptions, (i) to vote all Common Units held directly or indirectly by such partner in favor of the conversion of the Issuer into a Delaware corporation pursuant to a plan of conversion contemplated as of the date of the Support Agreement or pursuant to such other alternative transaction or series of transactions adopted by the Issuer, including a reorganization (as applicable, the “Conversion”) and any transaction or related matters thereto if the Issuer seeks unitholder approval and (ii) subject to certain exceptions, not to transfer any Common Units held directly or indirectly by such partner until the earlier of (x) the completion of such unitholder vote regarding the Conversion and (y) the Issuer’s determination to abandon or terminate the Conversion.

The Acquisition I Merger

Also on October 14, 2021, the Issuer entered into an agreement and plan of merger (the “Acquisition I Merger Agreement”) by and among Acquisition I, the Issuer, Enviva, Inc. Merger Sub, LLC (“Merger Sub”), and the Riverstone Echo Funds. Pursuant to the Acquisition I Merger Agreement, Acquisition I has agreed to merge with and into Merger Sub, with Merger Sub surviving as a wholly owned subsidiary of the Issuer (the “Acquisition I Merger”). The Riverstone Echo Funds will receive a number of shares of the post-Conversion corporation’s common stock equal to the number of Common Units held directly or indirectly by Acquisition I immediately prior to the Acquisition I Merger.

The Acquisition I Merger Agreement contains customary representations and warranties and covenant provisions. The consummation of the Acquisition I Merger is subject to the satisfaction of customary closing conditions, including the consummation of the Conversion, the performance by the parties, in all material respects, of their respective covenants as set forth in the Acquisition I Merger Agreement and, subject to certain exceptions, the accuracy of their respective representations and warranties as set forth in the Acquisition I Merger Agreement.

The Registration Rights Agreement

In connection with the Drop Merger, the Issuer entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with the Holdings Limited Partners party thereto pursuant to which, among other things and subject to certain restrictions, the Issuer is required to file with the U.S. Securities and Exchange Commission a registration statement on Form S-3 registering for resale (i) Common Units received by such Holdings Limited Partners in connection with the Drop Merger, (ii) common stock issuable to such Holdings Limited Partners in exchange for such Common Units upon consummation of the Conversion, and (iii) the DRIP Securities (as defined in the Support Agreement) issuable to such Holdings Limited Partners in connection with their commitment to reinvest dividends or distributions in respect of certain of such Common Units and common stock. The Registration Rights Agreement also provides the Holdings Limited Partners with customary demand and piggyback registration rights.

17

CUSIP No. 29414J107 13D Page 18 of 22 Pages

The Stockholders Agreement

In connection with the Drop Merger, the Issuer entered into a stockholders’ agreement (the “Stockholders Agreement”) with the Riverstone Echo Funds and each of their respective affiliates that will own shares of the Issuer’s common stock following the Conversion (collectively, the “Riverstone Stockholders”), which Stockholders Agreement will become effective upon the Conversion. The Stockholders Agreement provides for the composition of the Issuer’s initial post-Conversion board of directors. In addition, for so long as the Riverstone Stockholders hold at least 30% of the Issuer’s common stock, the Issuer agrees that it will not, without the approval of the Riverstone Stockholders:

· amend the Issuer’s certificate of incorporation or bylaws;

· undertake any transaction involving a merger of the Issuer or that would otherwise constitute a change of control;

· commence any voluntary dissolution, reorganization, recapitalization or liquidation of EVA;

· make a voluntary filing of a petition for bankruptcy or receivership by the Issuer, or fail to oppose any other person’s petition filed against the Issuer in any such proceeding;

· adopt any “poison pill” or shareholder rights plan;

· make any acquisition or disposition of assets or equity interests, in any transaction or series or related transactions, for aggregate consideration in excess of (A) 25% of the fair market value of the Issuer’s total assets or (B) 25% of the market capitalization of the Issuer, each as determined at the time of the approval of the agreement to enter into any such transaction or series of related transactions; or

· enter into any agreement to undertake or effect any of the foregoing actions.

The Stockholders Agreement will terminate upon the later of (a) such time as the Riverstone Stockholders hold less than 30% of the Issuer common stock and (b) the earlier of (1) the time at which the Issuer holds an annual meeting of its stockholders in 2022, if held, and (2) December 31, 2022.

Restricted Securities Agreements

Also in connection with the Drop Merger, the Riverstone Echo Funds entered into an agreement (the “Restricted Securities Agreements”) with each person who received Common Units in exchange for such person’s series B units of Enviva Holdings, LP (each such person, a “Holder”). Pursuant to the Restricted Securities Agreements, each Holder agreed that the Common Units received in exchange for the class B units will be designated as restricted securities and subject to forfeiture or retention and certain restrictions on transfer as set forth in the Restricted Securities Agreements. These restrictions will fall away with respect to 33% of the Common Units acquired in the Drop Merger on December 31, 2022, with respect to an additional 34% of the Common Units on December 31, 2023, and with respect to any remaining Common Units on December 31, 2024.

The foregoing descriptions of the Drop Merger Agreement, the Support Agreement, the Acquisition I Merger Agreement, the Registration Rights Agreement, the Stockholders Agreement and the Restricted Securities Agreements do not purport to be complete and are qualified in their entirety by reference to the full text of such agreements filed as exhibits to this Schedule 13D, and incorporated herein by reference.
