CommScope Reports Third Quarter 2015 Results

HICKORY, NC, November 9, 2015—CommScope Holding Company, Inc. (NASDAQ: COMM), a global leader in infrastructure solutions for communications networks, reported sales of $973 million and a net loss of $81 million, or $0.42 per share, for the quarter ended September 30, 2015. The reported net loss includes impairment charges, costs associated with the Broadband Network Solutions (BNS) acquisition and other special items. Excluding these items, non-GAAP adjusted net income for the third quarter of 2015 was $103 million, or $0.53 per diluted share. A reconciliation of reported GAAP results to non-GAAP results is attached.

For the quarter ended September 30, 2014, CommScope reported sales of $1.0 billion and net income of $96 million, or $0.50 per diluted share. Non-GAAP adjusted net income for the third quarter of 2014 was $119 million, or $0.62 per diluted share.

As previously announced, CommScope completed its acquisition of BNS from TE Connectivity on August 28, 2015. The results of the BNS business are included in CommScope’s results of operations from the date of the acquisition through September 25, 2015, its fiscal period end.

“We are pleased to welcome the talented BNS team to CommScope. This transformational acquisition broadens our leading position across diverse and growing markets, significantly expands our platform for innovative solutions and creates complementary market opportunities. Also, we continue to expect to realize significant synergy opportunities,” said President and Chief Executive Officer Eddie Edwards. “We are executing integration activities as planned and are excited about the market position of the new CommScope.

“Although slow spending from certain North American and European wireless operators is a near-term challenge, we expect longer-term demand for our Wireless solutions to be positively affected by wireless coverage and capacity expansion in emerging markets and the increasing demand for mobile broadband in developed markets. In addition, the strong fiber connectivity portfolio that BNS brings to CommScope positions us to benefit from the global shift toward fiber in next-generation communications networks.”

Third Quarter 2015 Overview

Third quarter 2015 sales declined 3 percent year over year to $973 million, including BNS revenue of $141 million. Foreign exchange rate changes negatively impacted sales by 3 percent in the quarter compared to the prior year period. The addition of the BNS business along with growth in the Enterprise segment was more than offset by lower Wireless and Broadband sales.

Operating loss in the third quarter of 2015 was $43 million. This loss reflects a goodwill impairment charge related to the Wireless segment, costs associated with the BNS acquisition and an impairment charge on a note receivable related to a previous divestiture in the Broadband segment. Excluding BNS, operating income was $39 million compared to operating income of $151 million in the year-ago quarter. Adjusted operating income in the quarter, which excludes impairment charges, costs associated with the BNS acquisition and other special items, was $201 million, which includes BNS adjusted operating income of $26 million.

GAAP net loss of $81 million for the third quarter of 2015 compares to GAAP net income of $96 million for the year-ago quarter. Excluding amortization of purchased intangibles, restructuring costs, transaction and integration costs and other special items, third quarter adjusted net income decreased 14 percent year over year to $103 million. Adjusted earnings were $0.53 per diluted share, down 15 percent year over year.

Third Quarter 2015 Segment Overview

Wireless segment sales in the quarter declined 25 percent year over year to $475 million. The year-over-year decrease was due to lower spending by wireless operators in most major geographic regions of the world after robust spending in 2014. Additionally, foreign exchange rate changes had a negative impact of approximately 5 percent on Wireless segment sales in the third quarter compared to the prior year period. Despite lower sales volumes, Wireless adjusted operating income was $99 million, or 21 percent of Wireless sales, for the quarter.

Third quarter Enterprise segment sales increased 4 percent year over year to $228 million, primarily driven by strong sales of data center fiber solutions and growth in most major geographic regions of the world. Foreign exchange rate changes had a negative impact of approximately 2 percent on Enterprise segment sales in the third quarter of 2015 compared to the prior year period. Enterprise adjusted operating income for the quarter increased 31 percent year over year to $58 million, or 26 percent of Enterprise sales, primarily due to higher fiber sales to data centers.

Third quarter Broadband segment sales decreased 14 percent year over year to $128 million. Sales decreased year over year primarily due to lower investment in the Central and Latin America region, as well as reduced sales in North America. Foreign exchange rate changes had a negligible impact on Broadband segment sales in the third quarter of 2015 compared to the prior year period. Broadband adjusted operating income decreased to $18 million, or 14 percent of Broadband sales. The decrease was primarily due to lower sales, partially offset by lower material costs and the benefit of cost reduction initiatives.

Broadband Network Solutions Acquisition

As previously stated, CommScope acquired TE Connectivity’s BNS business on August 28, 2015. BNS revenue of $141 million, GAAP operating loss of $82 million and adjusted operating income of $26 million were included in CommScope’s results of operations for the third quarter 2015. These results are from the acquisition date to September 25, 2015, the fiscal period end of BNS. BNS is being reported separately as a fourth segment.

“Integration teams are fully engaged across the company,” said Edwards. “We are establishing new business organizations, developing market strategies and executing on our three-year synergy plan. Overall, we have made solid progress in the first two months after the close of the acquisition.”

Outlook

CommScope management provided the following fourth quarter and full year 2015 guidance, which excludes the amortization of purchased intangibles, restructuring costs, transaction and integration costs, purchase accounting and other special items.

Non-GAAP Financial Measures

CommScope management believes that presenting certain non-GAAP financial measures provides meaningful information to investors in understanding operating results and may enhance investors’ ability to analyze financial and business trends. Non-GAAP measures are not a substitute for GAAP measures and should be considered together with the GAAP financial measures. As calculated, our non-GAAP measures may not be comparable to other similarly titled measures of other companies. In addition, CommScope 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.
