On August 28, 2015, pursuant to the terms of the stock and asset purchase agreement (the “Purchase Agreement”), dated as of January 27, 2015, by and among CommScope Holding Company, Inc. (“Holdings”), CommScope, Inc. (“CommScope” and, together with Holdings, the “Company”) and TE Connectivity Ltd., a Swiss corporation (“Seller”), the Company completed the acquisition of Seller’s Telecom, Enterprise and Wireless businesses (the “Business”), which Seller refers to as its Broadband Network Solutions business unit, pursuant to a combination of stock and asset purchases (the “Transaction”). Upon the closing of the Transaction, the Company paid to Seller approximately $3.0 billion in cash, subject to a final working capital adjustment and an additional adjustment related to assumed pension liabilities of the Business. In connection with the Transaction, under the terms of the Purchase Agreement, the Company also assumed certain other liabilities of the Business, including certain severance obligations triggered by the Transaction and certain outstanding restructuring liabilities related to the Business.

The foregoing description does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Purchase Agreement, which was filed as Exhibit 2.1 to Holdings’ Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on January 28, 2015, and which is incorporated herein by reference.

The Purchase Agreement was filed to provide investors with information regarding its terms and is not intended to provide any factual information about Holdings, CommScope, Seller or any of their respective subsidiaries or affiliates. Such information can be found in the public filings that Holdings or Seller, as applicable, files with the SEC. The representations, warranties and covenants contained in the Purchase Agreement were made solely for the purposes of the Purchase Agreement and are as of specific dates and solely for the benefit of the parties to the Purchase Agreement and:

Accordingly, investors should not rely on the representations, warranties or covenants or any descriptions thereof as characterizations of the actual state of facts or condition of Holdings, CommScope, Seller or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations and warranties may change, or may have changed, after the date of the Purchase Agreement, which subsequent information may or may not be fully reflected in Holdings’ or Seller’s public disclosures. Accordingly, the representations and warranties and other provisions of the Purchase Agreement or any description of such provisions should not be read alone, but instead should be read together with the information that each company publicly files in reports and statements with the SEC.

On August 28, 2015, the Company issued a press release announcing the completion of the Transaction. A copy of the press release is attached hereto as Exhibit 99.1, which is incorporated herein by reference.
