No Offer or Solicitation

This communication is not a proxy statement or solicitation of a proxy, consent or authorization with respect to any securities or in respect of the potential transaction and shall not constitute an offer to sell or a solicitation of an offer to buy the securities of E2open or BluJay, nor shall there be any sale of any such securities in any state or jurisdiction in which such offer, solicitation, or sale would be unlawful prior to registration or qualification under the securities laws of such state or jurisdiction.

Forward-Looking Statements

Certain statements in this Current Report on Form 8-K may be considered forward-looking statements. Forward-looking statements generally relate to future events or E2open’s or BluJay’s future financial or operating performance. For example, projections of future growth, financial performance, and other metrics are forward-looking statements. In some cases, you can identify forward-looking statements by terminology such as “may,” “should,” “expect,” “intend,” “will,” “estimate,” “anticipate,” “believe,” “predict,” “potential” or “continue,” or the negatives of these terms or variations of them or similar terminology. Such forward-looking statements are subject to risks, uncertainties, and other factors which could cause actual results to differ materially from those expressed or implied by such forward looking statements.

These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by E2open and its management, and BluJay and its management, as the case may be, are inherently uncertain. Factors that may cause actual results to differ materially from current expectations include, but are not limited to: (1) the occurrence of any event, change or other circumstances that could give rise to the termination of negotiations and any subsequent definitive agreements with respect to the Transaction; (2) the outcome of any legal proceedings that may be instituted against E2open, BluJay, the combined company or others following the announcement of the Transaction and any definitive agreements with respect thereto; (3) the inability to complete the Transaction due to the failure to obtain approval of the stockholders of E2open, to obtain financing to complete the Transaction or to satisfy other conditions to closing; (4) changes to the proposed structure of the Transaction that may be required or appropriate as a result of applicable laws or regulations or as a condition to obtaining regulatory approval of the Transaction; (5) the ability to meet stock exchange listing standards following the consummation of the Transaction; (6) the risk that the Transaction disrupts current plans and operations of BluJay as a result of the announcement and consummation of the Transaction; (7) the ability to recognize the anticipated benefits of the Transaction, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably, maintain relationships with customers and suppliers and retain its management and key employees; (8) costs related to the Transaction; (9) changes in applicable laws or regulations; (10) the possibility that BluJay or the combined company may be adversely affected by other economic, business, and/or competitive factors; (11) BluJay’s estimates of expenses and profitability; and (12) other risks and uncertainties set forth in E2open’s filings with the SEC, including in the section entitled “Risk Factors” and “Forward-Looking Statements” in E2open’s definitive proxy statement related to the Transaction and Annual Report on Form 10-K for the year ended February 28, 2021.

Nothing in this Current Report on Form 8-K should be regarded as a representation by any person that the forward-looking statements set forth herein will be achieved or that any of the contemplated results of such forward-looking statements will be achieved. You should not place undue reliance on forward-looking statements, which speak only as of the date they are made. Neither E2open nor BluJay undertakes any duty to update these forward-looking statements.
