Item 8.01 Other Events.

On May 3, 2018, the Board of Directors (the “Board”) of Advanced Energy Industries, Inc. (the “Company”) approved an amendment to the Company's Restated Certificate of Incorporation to provide that subparagraph (3) of paragraph A. of Article V of the Restated Certificate of Incorporation shall be amended to read in its entirety as follows:

(3) Subject to the rights of the holders of any series of Preferred Stock, any director may be removed with or without cause. Subject to any limitations imposed by law, the Board of Directors or any individual director may be removed from office at any time with or without cause by the affirmative vote of the holders of a majority of the voting power of all the then-outstanding shares of voting stock of the corporation entitled to vote at an election of directors (the "Voting Stock").

The Board deems the amendment advisable and directs that the amendment be submitted to the stockholders of the Company for approval at the 2019 Annual Meeting of Stockholders. The amendment will not be effective until it has been approved by the vote of the stockholders of the Company as required under the Delaware General Corporation Law and the Restated Certificate of Incorporation. Until the amendment to the Restated Certificate of Incorporation is effective, the Company will comply with the Company’s By-laws, as amended, in respect of removal of directors and not attempt to enforce the provisions of Article V, paragraph A(3) of the Restated Certificate of Incorporation requiring “cause” for removal of a director.


Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
