CommScope Reports Strong First Quarter 2014 Results

HICKORY, NC, April 30, 2014—CommScope Holding Company, Inc. (NASDAQ: COMM), a global provider of connectivity and essential infrastructure solutions for wireless, business enterprise and residential broadband networks, reported sales of $935 million and net income of $64 million or $0.34 per diluted share for the quarter ended March 31, 2014. Non-GAAP adjusted net income was $95 million or $0.50 per diluted share. A reconciliation of reported GAAP results to non-GAAP results is attached.

For the quarter ended March 31, 2013, CommScope reported sales of $805 million and net income of $16 million or $0.10 per diluted share. Non-GAAP adjusted net income was $55 million or $0.35 per diluted share.

“We are pleased to deliver outstanding results to start the year,” said President and Chief Executive Officer Eddie Edwards. “We executed well and built upon the positive momentum we created heading into 2014. We are particularly proud of our Wireless team as they delivered especially strong results. It was also good to see year-over-year growth in our Enterprise segment, which benefitted from improved corporate IT investment and our investment in new solutions.

“Consumers want a high quality mobile broadband network and U.S. wireless operators are investing in our industry-leading cell site and small cell DAS solutions for increased capacity and the densification of their networks. Wireless operators outside the U.S. are also in the process of modernizing existing networks and planning for the initial roll out of LTE networks. We believe that CommScope is very well positioned to benefit from these positive global trends.”

First Quarter Overview

First quarter 2014 sales rose $130 million, or 16 percent, year over year to $935 million. Orders booked in the first quarter of 2014 were particularly strong, up 30 percent year over year to $1.1 billion. The robust order growth was driven primarily by the Wireless segment, with particular strength in North America.

Operating income in the first quarter 2014 grew 96 percent to $147 million, compared to $75 million in the year-ago quarter. Adjusted operating income, which excludes amortization of purchased intangibles, restructuring costs and other special items, rose 45 percent to $192 million, an increase of $60 million compared to the prior year period.

GAAP net income rose substantially to $64 million, compared to net income of $16 million in the year-ago period. Excluding amortization of purchased intangibles, restructuring costs and other special items, adjusted first quarter net income increased $40 million, or 74 percent, year over year to $95 million.

First Quarter Segment Overview

Wireless segment sales increased 26 percent year over year to $627 million. The increase was primarily driven by higher spending in the U.S. and the Europe, Middle East and Africa region. Customers continue to consume increasing amounts of data over licensed spectrum, and to meet this growth, wireless operators are investing in CommScope’s industry leading cell-site and small cell DAS solutions. In the quarter, Wireless adjusted operating income rose 63 percent year over year to $154 million, or 25 percent of sales.

Enterprise segment sales increased 5 percent year over year to $202 million and is the first quarter of year-over-year growth since 2011. The increase is primarily due to higher sales in the U.S. and Central and Latin America region. While corporate IT investment has been cautious over a multi-quarter period, continued bandwidth demand and improving economic conditions have created a better commercial environment. Enterprise adjusted operating income increased 5 percent year over year to $36 million or 18 percent of sales.

Broadband segment sales declined 9 percent year over year to $108 million. Adjusted operating income declined 43 percent year over year to $2 million, or 2 percent of sales. The profit decline is due primarily to lower sales prices and sales volume. However, Broadband performance improved sequentially and cost reduction activities were initiated in the fourth quarter of 2013 to better align this segment’s cost structure with customer demand. As a result, we expect adjusted operating income improvement throughout the remainder of 2014. We also continue to evaluate alternatives to improve the performance of the Broadband segment.

CommScope management provided the following second quarter and full year 2014 guidance, which excludes the amortization of purchased intangibles, restructuring costs and other special items:
