Amendment Description On March 2, 2020, Tidewater Inc. filed its Annual Report on Form 10-K for the fiscal year ended December 31, 2019 (the “Original Form 10-K”) with the Securities and Exchange Commission (the “SEC”).  Tidewater is filing this Amendment No. 1 on Form 10-K/A (the “Form 10-K/A”) because it will not file its definitive proxy statement within 120 days after the end of such fiscal year.  Therefore, this Form 10-K/A is being filed for the purposes of (1) providing the information required in Part III of Form 10-K, which was previously omitted in reliance on General Instruction G(3) to Form 10-K, (2) updating the information required in Item 1A of Part I of Form 10-K with respect to the additional risks associated with the global outbreak of a novel strain of coronavirus in early 2020 as well as the disruptions in the global energy markets, given that a brief discussion of these recent developments is included in Part III, and (3) providing information regarding our 2020 annual meeting of stockholders in Item 10 of Part III.   In addition, as required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), a certification by Tidewater’s principal executive and financial officer is filed as an exhibit to this Form 10-K/A under Item 15 of Part IV.  Because no financial statements have been included in this Form 10-K/A and this Form 10-K/A does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. We are not including the certifications under Section 906 of the Sarbanes-Oxley Act of 2002 as no financial statements are being filed with this Form 10-K/A. Except as described above, this Form 10-K/A does not reflect events occurring after the date of the Original Form 10-K and does not modify or update disclosures contained in the Original Form 10-K including, without limitation, the financial statements. Information not affected by this Form 10-K/A remains unchanged and reflects the disclosures made at the time the Original Form 10-K was filed. Accordingly, this Form 10-K/A should be read in conjunction with the Original Form 10-K and our other filings with the SEC. In this Form 10-K/A, unless the context indicates otherwise, the designations “Tidewater,” the “company,” “we,” “us,” or “our” refer to Tidewater Inc. and its consolidated subsidiaries. This document includes several website references. The information on these websites is not part of this Form 10-K/A.
