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

As previously announced, on November 8, 2018, ARRIS International plc (the “Company” or “ARRIS”), entered into a Bid Conduct Agreement (as amended, the “Acquisition Agreement”) with CommScope Holding Company, Inc. (“CommScope”), pursuant to which CommScope has agreed to acquire all of the issued and to be issued ordinary shares of ARRIS (the “Acquisition”) for $31.75 in cash per ordinary share of ARRIS (“Ordinary Share”). The Acquisition will be effected pursuant to a scheme of arrangement (the “Scheme”) under Part 26 of the Companies Act 2006.

On February 1, 2019, ARRIS held a meeting of shareholders convened by the High Court of Justice in England and Wales (the “Court Meeting”) and a special general meeting of shareholders (the “General Meeting”), in each case relating to the pending Acquisition. ARRIS’s shareholders approved each of the proposals to be acted on at the Court Meeting and the General Meeting, in each case by the requisite majorities. All votes at both the Court Meeting and the General Meeting were conducted on a poll.

The consummation of the Acquisition remains subject to various closing conditions, including, among other things, (i) the sanction of the Scheme by the High Court of Justice of England and Wales, (ii) the receipt of certain required regulatory approvals or lapse of certain review periods with respect thereto, (iii) the absence of a Company Material Adverse Effect (as defined in the Acquisition Agreement), (iv) the accuracy of representations and warranties (subject, in certain cases, to certain materiality or Company Material Adverse Effect qualifiers, as applicable) and (v) the absence of legal restraints prohibiting or restraining the Acquisition.

The final results of voting on each of the items submitted to a vote of ARRIS’s shareholders at the Court Meeting and the General Meeting are as follows:
