Item 7.01 Regulation FD Disclosure.

On May 20, 2015, CommScope Holding Company, Inc. (the “Company”) announced its intention to use capacity under the term loan portion of its senior secured credit facilities (the “existing term loan facility”) to obtain a new incremental term loan (the “incremental term loan facility”) with a principal amount of up to $1,250 million and a seven-year term.

The Company also intends that its wholly owned subsidiaries, CommScope Technologies Finance LLC (the “Unsecured Notes Issuer”) and CommScope, Inc. (the “Secured Notes Issuer”) expect to commence an offering (the “Offering”) of $1,500 million in aggregate principal amount of senior unsecured notes due 2025 (the “Unsecured Notes”) by the Unsecured Notes Issuer and $500 million in aggregate principal amount of senior secured notes due 2020 (the “Secured Notes” and, together with the Unsecured Notes, the “Notes”) by the Secured Notes Issuer, subject to market conditions. The Offering is expected to be made to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to certain non-U.S. persons in accordance with Regulation S under the Securities Act.

The Company expects to use the net proceeds of the offering of the Unsecured Notes and the borrowings under the incremental term loan facility, along with cash on hand, to fund the Company’s acquisition (the “Acquisition”) of the Broadband Network Solutions business of TE Connectivity, Ltd. (“Seller” or “TE Connectivity”), and to pay certain fees and related expenses. In addition, the Company expects to use the net proceeds of the offering of the Secured Notes, along with cash on hand, to repay a portion of the principal amount outstanding under its existing term loan facility (the “Refinancing”).

The Notes will not be registered under the Securities Act, or any state securities laws, and may not be offered or sold in the United States absent registration, except pursuant to an exemption from the registration requirements of the Securities Act and applicable state securities laws. This Current Report is neither an offer to sell nor a solicitation of an offer to buy any of these securities, and shall not constitute an offer, solicitation or sale in any jurisdiction in which such an offer, solicitation or sale would be unlawful.

The foregoing information is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such filing.

Item 8.01 Other Events.

In connection with the Acquisition, the Company is filing this Current Report on Form 8-K in order to make publicly available certain unaudited historical financial information of Seller’s Broadband Network Solutions business and unaudited pro forma financial information of the Company reflecting the Acquisition and the Refinancing described in Items 9.01(a) and (b) below and incorporated by reference herein.

Additionally, the Company is providing the following financial information regarding Seller’s Broadband Network Solutions business for the six-month periods ended March 27, 2015 and March 28, 2014, the fiscal year ended September 26, 2014 and the twelve months ended March 27, 2015 ($ in millions):

Note: Components may not sum to total due to rounding.

The Company’s management believes that presenting the above non-GAAP financial measures provides meaningful information to investors in understanding operating results and may enhance investors’ ability to analyze financial and business trends. As calculated, these non-GAAP measures may not be comparable to other similarly titled measures of other companies. In addition, the Company’s management believes that these non-GAAP financial measures allow investors to compare period to period more easily by excluding items that could have a disproportionately negative or positive impact on results in any particular period.

The Company expects to realize more than $150 million in annual synergies beginning in the third year following closing, with more than $50 million in the first full year. These synergies are expected to come from all areas of the company, including sales, marketing, general and administrative, operations and research and development. The Company expects to incur integration and restructuring costs of $125 million - $175 million to achieve these synergies.
