<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">HOUSTON&#151;(BUSINESS WIRE)&#151;October 30, 2019 - Tidewater Inc. (NYSE: TDW) (&#147;Tidewater&#148; or the &#147;Company&#148;) is pleased to announce that
Mr.&nbsp;Larry&nbsp;T. Rigdon has been elected Chairman of the Board of Tidewater Inc. effective October 28<SUP STYLE="font-size:85%; vertical-align:top">th</SUP>. Mr.&nbsp;Rigdon replaces Dr.&nbsp;Thomas&nbsp;R. Bates, Jr., who has recently
resigned from the board. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Mr.&nbsp;Rigdon has been a member of the Tidewater Board of Directors since August 2017. He has extensive prior experience as an
executive at Tidewater.&nbsp;&nbsp;&nbsp;&nbsp;Mr.&nbsp;Rigdon served as Interim Chief Executive Officer of Tidewater for the five-month period ended March 2018 and had previously joined the Company in 1992 upon the merger with Zapata Gulf Marine
Corporation. After successive roles of increasing responsibility, he left the Company as Executive Vice President in 2002. He then successfully founded and grew Rigdon Marine Corporation to an owner of 28 offshore service vessels, selling the
company in June 2008 to GulfMark Offshore, Inc. (&#147;GulfMark&#148;), where he became a board member thereof until 2010. Mr.&nbsp;Rigdon also currently serves as a director of Professional Rental Tools, LLC. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Coincident with the merger of Tidewater and GulfMark in 2018, the Tidewater board was expanded from seven to ten members. Since then, the board has been in a
process of determining its optimal size and composition. The board determined that operational efficiency is a key success factor for the Company as it addresses long-standing challenges facing the OSV industry and executes on the opportunities
afforded the industry&#146;s best-capitalized and leading global operator. In this regard, the board is committed to lead by example and will &#147;do more with less&#148;. The board believes a smaller board will not only be more cost-effective, but
will enable the board to be more responsive and efficient as it advances the Company&#146;s strategic goals. Accordingly, the board committed to a reduction in its size to seven members at the next annual meeting of stockholders. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Additionally, the Company announces that the size of the board has been reduced from ten to eight members effective immediately. The immediate reduction in
board size is the result of the resignation of Dr.&nbsp;Thomas&nbsp;R. Bates, Jr. and Mr.&nbsp;Steven&nbsp;L. Newman. These resignations were not the result of any known disagreements between the resigning directors and management or the board of
Tidewater. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In connection with these changes, the board has appointed, effective immediately, Ms.&nbsp;Randee&nbsp;E. Day to be Chairwoman of the
Nominating&nbsp;&amp; Governance Committee, Mr.&nbsp;Louis&nbsp;A. Raspino to be Chairman of the Compensation Committee, and has confirmed Mr.&nbsp;Dick&nbsp;H. Fagerstal as Chairman of the Audit Committee. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The seven directors that the Tidewater board intends to nominate for election at the 2020 annual meeting of stockholders are: Randee E. Day, Dick H.
Fagerstal, Quintin V. Kneen, Louis A. Raspino, Larry T. Rigdon, Robert P. Tamburino and Kenneth H. Traub. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Larry T. Rigdon, Chairman of the Board of Tidewater, commented, &#147;I am thrilled to be taking over the
leadership of the Tidewater board at this important time in the company&#146;s history. The board made an important decision recently in appointing Quintin V. Kneen as our President and Chief Executive Officer, and he has our complete support.
Quintin is already doing a fantastic job in leading Tidewater with improved capital discipline and accountability, more efficient operations and expanding strategic opportunities. With our streamlined and focused board and the strong management team
led by Quintin, I am confident that Tidewater is well-positioned for long-term success.&#148; </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Quintin V. Kneen, Tidewater&#146;s President and Chief
Executive Officer, commented, &#147;Market conditions across all of our operating areas are showing signs of recovery. Although the industry remains oversupplied, the potential to create long-term value through consolidation and disciplined capital
management is clearer today than it has been in the past 5 years. We have been aggressively restructuring our shore base operations and our management structure over the past two months to improve the efficiency and scalability of our operations.
Our strong balance sheet, combined with the successful rollout in October of our enhanced information system, positions Tidewater as the only market participant with a scalable global infrastructure capable of significant consolidation in the
offshore support vessel industry.&#148; </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>About Tidewater </B></P>
