Item 5.07. Submission of Matters to a Vote of Security Holders.

On October 16, 2025, CommScope Holding Company, Inc., a Delaware corporation (the “Company”), issued a press release announcing that at a special meeting of stockholders of the Company held on October 16, 2025, its stockholders approved the proposal (the “CCS Sale Proposal”) to adopt the Purchase Agreement, dated as of August 3, 2025, by and between Amphenol Corporation and the Company, and approve the transactions contemplated thereby, including the sale of the Company’s Connectivity and Cable Solutions segment to Amphenol Corporation (the “CCS Sale Transaction”). The stockholders of the Company also approved the proposal to approve, on an advisory, non-binding basis, certain compensation that has, will or may be paid or become payable to the Company’s named executive officers in connection with the CCS Sale Transaction (the “Advisory Compensation Proposal”). The stockholders of the Company also voted to approve the proposal to adjourn or postpone the special meeting, if necessary or appropriate, for the purpose of soliciting additional votes for the approval of the CCS Sale Proposal (the “Adjournment Proposal”). However, given the outcome of the vote on the CCS Sale Proposal, it was not necessary to adjourn or postpone the special meeting to a later date.

The holders of shares of common stock and shares of Series A Convertible Preferred Stock, voting together as a single class (with the holders of Series A Convertible Preferred Stock voting on an as-converted basis as described in the Proxy Statement), voted on the three proposals at the special meeting. The final voting results for each proposal are set forth below:

A copy of the press release issued by the Company regarding the results of the stockholder vote at the special meeting of stockholders of the Company is filed as Exhibit 99.1 to this report and is incorporated herein by reference.
