Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On January 21, 2018, the Board of Directors (the “Board”) of Tenet Healthcare Corporation (the “Company”) approved amendments to the Company’s Amended and Restated Bylaws (as amended, the “Bylaws”) to grant stockholders the right to call a special meeting. Prior to this amendment, the Bylaws provided that only the Chairman of the Board, the Company’s Chief Executive Officer or the Board itself could call special meetings of the stockholders.    

The specific sections of the Bylaws amended were Section 2.3 (“Special Meetings”) and Section 2.10.2 (“Notice of Stockholder Business and Nominations—Special Meetings of Stockholders”). The amendments permit one or more stockholders that own shares representing at least a majority of all outstanding shares of common stock of the Company to call a special meeting, provided that the stockholder(s) satisfy the procedural requirements set forth in the Bylaws. The amendments include, among other things, provisions relating to the stockholder ownership conditions required to request a special meeting, the procedural requirements to request a special meeting (including applicable time periods), and the circumstances under which the Company can decline to hold a requested special meeting.    

The foregoing description of the Bylaws is not complete and is qualified in its entirety by reference to the Bylaws, which are filed as Exhibit 3.1 hereto in redline form showing the amendments described above, and as Exhibit 3.2 hereto in unmarked form, and are incorporated herein by reference.
