This Amendment No. 3 (“Amendment No. 3”) amends the Schedule 13D originally filed with the U.S. Securities and Exchange Commission (the “Commission”) on August 3, 2017, as amended (as amended, the “Statement”), and is filed by the Reporting Persons with respect to the common stock, $0.0001 par value per share (“Shares”), of NextDecade Corporation (the “Issuer”).  Capitalized terms used herein but not defined shall have the meaning given to them in the Statement.

Item 4. Purpose of Transaction.

Item 4 is amended and supplemented as follows:

On April 11, 2018 (the “Backstop Agreement Date”), Halcyon Management entered into a backstop commitment agreement with the Issuer (the “Backstop Agreement”), pursuant to which Halcyon Management or its designated affiliates (as described below), agreed to purchase in the aggregate, at the Issuer’s election, up to approximately $3.845 million in, or approximately 3,845 shares of, convertible preferred stock with detached warrants (such commitment, the “Halcyon Backstop Amount”) in connection with the Issuer’s convertible preferred equity offering (“preferred offering”) previously disclosed in the Issuer’s Form 8-K filed with the SEC on April 12, 2018 (the “Backstop 8-K”).

Pursuant to the Backstop Agreement, in exchange for Halcyon Management’s commitment under the Backstop Agreement, the Issuer agreed to issue to Halcyon Management, or its designated affiliates, at the closing of the preferred offering (the “Closing”), an aggregate of 24,007 Shares if the Closing occurs within 30 days after the Backstop Agreement Date and additional Shares if the Closing occurs at a later date (as set forth in the Backstop Agreement).  In addition, the Issuer agreed to issue to Halcyon Management, or its designated affiliates, an amount equal to 2.75% of the portion of the Halcyon Backstop Amount drawn on by the Issuer, which will be paid at the Closing in Shares priced at $4.8047 per share.
