On March 15, 2019, the board of directors (the “Board”) of SEACOR Marine Holdings Inc. (the “Company”) amended and restated the Company’s bylaws (the “Third Amended and Restated Bylaws”). The amendment and restatement amends Article XIII of the prior bylaws of the Company to reduce the stockholder vote required to amend the bylaws from not less than 66 2/3% of the voting power of the outstanding shares of common stock entitled to vote thereon to not less than a majority of the voting power of the outstanding shares of common stock entitled to vote thereon.

A copy of the Third Amended and Restated Bylaws is attached hereto as Exhibit 3.1 and is incorporated herein by reference. 

Item 8.01. Other Events.

The Board has established June 11, 2019 as the date of the Company’s 2019 Annual Meeting of Stockholders (the “2019 Annual Meeting”). The record date for the 2019 Annual Meeting will be April 18, 2019. The time and location of the 2019 Annual Meeting will be specified in the Company’s proxy statement for the 2019 Annual Meeting.

The Board of Directors has determined to submit to stockholders for approval at the 2019 Annual Meeting an amendment and restatement of the certificate of incorporation of the Company. The amendment and restatement would amend Articles Fifth and Sixth of the prior certificate of incorporation of the Company to reduce the share ownership required for stockholders to act by written consent or to approve a merger or certain other extraordinary transaction from, in each case, not less than 66 2/3% of the voting power of the outstanding shares of common stock to not less than a majority of the voting power of the outstanding shares of common stock.
