CommScope Reports Strong Third Quarter 2014 Results

HICKORY, NC, October 31, 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 $1.0 billion and net income of $96 million, or $0.50 per diluted share for the quarter ended September 30, 2014. Non-GAAP adjusted net income was $119 million, or $0.62 per diluted share. A reconciliation of reported GAAP results to non-GAAP results is attached.

For the quarter ended September 30, 2013, CommScope reported sales of $888 million and net income of $11 million, or $0.07 of earnings per diluted share. Non-GAAP adjusted third quarter 2013 net income was $61 million, or $0.38 of earnings per diluted share.

“We are pleased to deliver a strong third quarter as our Wireless, Enterprise and Broadband segments all delivered solid results,” said President and Chief Executive Officer Eddie Edwards. “In the quarter, we saw robust sales for our cell site and small cell DAS wireless solutions, sales growth and meaningful operating margin improvement in Broadband and continued positive trends in Enterprise.

“As previously highlighted, we continue to expect stronger wireless spending in the first half of 2014 compared to the second half of 2014. However, continued global investment in LTE coverage and capacity over licensed spectrum will remain a strategic initiative for wireless operators over the long term. Combined with Enterprise growth opportunities, Broadband margin improvement and our global scale and service model, we are well positioned to benefit from operator investment in next generation networks.”

Third Quarter Overview

Third quarter 2014 sales rose $112 million, or 13 percent, year over year to $1.0 billion. Operating income in the third quarter grew 51 percent to $151 million, compared to $100 million in the year-ago quarter. Adjusted operating income, which excludes amortization of purchased intangibles, restructuring costs and other special items, rose 35 percent to $219 million, an increase of $56 million compared to the prior year period.

GAAP net income rose substantially to $96 million, compared to net income of $11 million in the year-ago period. Excluding amortization of purchased intangibles, restructuring costs and other special items, third quarter adjusted net income increased $59 million, or 97 percent, year over year to $119 million.

Third Quarter

Segment Overview

Wireless segment sales increased 15 percent year over year to $633 million. The increase was primarily driven by growth in the Asia Pacific region and Europe as operators continued to invest in CommScope’s industry leading cell site and small cell DAS solutions. In addition, the Alifabs acquisition announced in July provided incremental sales of $10 million in the quarter. Wireless adjusted operating income rose 33 percent year over year to $155 million, or 25 percent of sales.

Enterprise segment sales increased 3 percent year over year to $218 million. The increase was primarily driven by growth in the Asia Pacific and North American regions. Large enterprises continue to invest in data centers, and we believe the intelligent building market is showing signs of modest improvement. Enterprise adjusted operating income increased 6 percent year over year to $45 million, or 20 percent of sales.

Broadband segment sales increased 20 percent year over year to $150 million. The increase was primarily driven by increased investment in North America as cable operators push fiber deeper in the network and invest to increase the quality of their video and broadband offerings. Broadband adjusted operating income increased meaningfully year over year to $19 million, or 13 percent of sales. The increase was driven by higher volumes and the benefit realized from cost reduction initiatives.

Outlook

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