DEREGISTRATION OF SECURITIES

This Post-Effective Amendment No. 1 relates to each of the following Registration Statements on Form S-8 (collectively, the “Registration Statements”) originally filed by Tidewater Inc., a Delaware corporation (the “Registrant”) with the Securities and Exchange Commission:

As previously disclosed, on May 17, 2017, the Registrant and certain of its subsidiaries (collectively, the “Debtors”) filed voluntary petitions for relief under chapter 11 of title 11 of the United States Code in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Cases,” and such court, the “Bankruptcy Court”). On July 17, 2017, the Bankruptcy Court issued a written order (the “Confirmation Order”) confirming the Second Amended Joint Prepackaged Chapter 11 Plan of Reorganization of the Debtors, as modified by the Confirmation Order (the “Plan”). On July 31, 2017, the Plan became effective in accordance with its terms and the Debtors emerged from the Bankruptcy Cases.

As a result of the Plan, the Registrant has terminated all offerings of securities pursuant to the Registration Statements. In accordance with an undertaking made by the Registrant in each Registration Statement to remove from registration, by means of a post-effective amendment, any of the securities that had been registered for issuance that remain unsold at the termination of such offering, the Registrant hereby removes from registration any and all securities registered but unsold under the Registration Statements and terminates the effectiveness of each Registration Statement.
