Tidewater announced that Larry T. Rigdon has been elected Chairman of the Board of Tidewater Inc. effective October 28. Rigdon replaces Dr. Thomas R. Bates, Jr., who has recently resigned from the board. Rigdon has been a member of the Tidewater Board of Directors since August 2017. He has extensive prior experience as an executive at Tidewater. 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. 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. Thomas R. Bates, Jr. and Mr. Steven L. Newman. These resignations were not the result of any known disagreements between the resigning directors and management or the board of Tidewater. In connection with these changes, the board has appointed, effective immediately, Ms. Randee E. Day to be Chairwoman of the Nominating & Governance Committee, Mr. Louis A. Raspino to be Chairman of the Compensation Committee, and has confirmed Mr. Dick H. Fagerstal as Chairman of the Audit Committee.
