On November 10, 2016, the Board of Directors of CommScope Holding Company, Inc. (the “Company”) amended and restated the Company’s Bylaws to change the standard for the election of directors in uncontested elections from a plurality voting standard to a majority voting standard and to make certain other minor changes. Under the amended provisions, in a contested election, directors will continue to be elected by a plurality of the shares represented in person or by proxy at any such meeting and entitled to vote on the election of directors.

In connection with the amendment, the Board also amended the Company’s Corporate Governance Guidelines to require an incumbent director who fails to receive the required number of votes in an uncontested election to tender his or her resignation to the Board. The Corporate Governance Guidelines, as amended, provide that the Nominating Committee of the Board will act to determine whether to accept the director’s resignation and will submit such recommendation for prompt consideration by the Board. The Corporate Governance Guidelines, as amended, require that the Board disclose publicly its decision and rationale with respect to the tendered resignation within 90 days following certification of the stockholder vote.

The foregoing summary of the Third Amended and Restated Bylaws and the Corporate Governance Guidelines do not purport to be complete and are qualified in their entirety by reference to the full text of the Third Amended and Restated Bylaws, that are attached hereto as Exhibit 3.1 and incorporated by reference herein, and to the Corporate Governance Guidelines, as amended, which are available on the Company’s website at www.commscope.com under “Investor Relations—Corporate Governance.” Additionally, a copy of the Third Amended and Restated By-laws, marked to show changes to the Second Amended and Restated By-laws, is also included as Exhibit 3.2 hereto (additions are underlined and deletions are struck through).
