Item 1. Security and Issuer

This Amendment No. 1 (this “Amendment”) amends and supplements the Statement on Schedule 13D filed with the Securities and Exchange Commission (the “Commission”) February 16, 2021, (the “Schedule 13D”) by the Reporting Persons (as defined therein). The Schedule 13D relates to shares of Class A Common Stock, par value $0.0001 per share (the “Class A Common Stock”) of E2open Parent Holdings, Inc., a Delaware corporation (“E2open”), whose principal executive offices are located at 9600 Great Hills Trail, Suite 300E, Austin, Texas 78759. This Amendment is being filed as a result of the entry by certain of the Reporting Persons into the Support Agreement as defined and described herein. Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to them in the Schedule 13D. Except as otherwise provided herein, all Items of the Schedule 13D remain unchanged.

Item 4. Purpose of Transaction.

The information contained in Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following in front of the final two paragraphs thereof:

Support Agreement for BluJay Transaction

On May 27, 2021, E2open entered into (a) a Share Purchase Deed (the “Purchase Agreement”) by and among E2open, BluJay TopCo Limited, a private limited liability company registered in England and Wales (“BluJay”), and the sellers party thereto (collectively, the “Sellers”) and (b) a Management Warranty Deed (the “Management Warranty Deed”) by and among E2open and the warrantors party thereto. The Purchase Agreement provides that, upon the terms and subject to the conditions set forth in the Purchase Agreement, E2open will directly or indirectly acquire all of the outstanding equity interests of BluJay, and BluJay will become a direct or indirect wholly owned subsidiary of E2open (the “Transaction”).  Upon consummation of the Transaction (“Completion”), the Sellers shall collectively receive (i) 72,383,299 shares of Class A common stock, par value $0.0001 per share, of E2open and (ii) cash consideration in the amount of $456,767,623, subject to adjustment as provided in the Purchase Agreement.

In connection with the Transaction, IVP GBCF Cayman, IVP GBCF Delaware, IVP IX Cayman, IVP IX Delaware and Aggregator (the “Support Agreement Signatories”) have entered into a Support Agreement, dated May 27, 2021, with E2open (the “Support Agreement”). Subject to the terms and conditions of the Support Agreement, the Support Agreement Signatories have agreed, among other things and subject to the respective terms thereof, to vote their shares of Common Stock (a) in favor of the transactions contemplated by the Purchase Agreement, including the issuance of the Common Stock as consideration to the Sellers and amending the Certificate of Incorporation of Purchaser to increase the authorized number of shares of Class A Common Stock (in order to facilitate the issuance of such shares of Common Stock), (b) in favor of any action, proposal, transaction or agreement that is submitted by E2open for a vote of the stockholders of E2open and would reasonably be expected to facilitate the transactions contemplated by the Purchase Agreement, (c) in favor of any proposal to adjourn or postpone to a later date any meeting of the stockholders of E2open at which any of the foregoing matters are submitted for consideration and vote of the stockholders of E2open if there are not sufficient votes for approval of any such matters on the date on which the meeting is held, and (d) against approval of (i) any proposal made in opposition to the Purchase Agreement or the consummation of the Transaction, (ii) any action or agreement that would result in a breach of any covenant, representation or warranty or any other obligation or agreement of E2open contained in the Purchase Agreement, or of such Supporting Stockholder contained in the Support Agreement, and (iii) any other action that would reasonably be expected to materially impede, materially interfere with, materially delay, materially postpone or materially and adversely affect or prevent the transactions contemplated by the Purchase Agreement or the Support Agreement.

The Support Agreement will terminate upon the earliest to occur of the termination of the Purchase Agreement and Completion. The Support Agreement limits the ability of the Support Agreement Signatories to transfer their shares of Common Stock in a manner which results in the Support Agreement Signatories ceasing to have the right to vote or direct the vote of such Common Stock, subject to certain exceptions, including that the Support Agreement Signatories may transfer their shares of Common Stock to certain permitted transferees.
