- Reaffirms full year 2018 outlook -

HICKORY, NC, July 31, 2018—CommScope Holding Company, Inc. (NASDAQ: COMM), a global leader in infrastructure solutions for communications networks, today reported results for the quarter ended June 30, 2018.

The company reported sales of $1.24 billion for the second quarter, compared with $1.17 billion during the same period in the prior year. During the second quarter of 2018, CommScope achieved net income of $66 million, or $0.34 per diluted share, which was an increase from the prior year period’s net income of $55 million, or $0.28 per diluted share. Non-GAAP adjusted net income for the second quarter of 2018 was $133 million, or $0.68 per diluted share, versus $119 million, or $0.60 per diluted share, in the second quarter of 2017. A reconciliation of reported GAAP results to non-GAAP results is attached.

“We are pleased to deliver solid second quarter results, which reflect our team’s focus on capitalizing on growth opportunities in our core markets while managing costs effectively,” said President and Chief Executive Officer Eddie Edwards. “The strong year-over-year growth in North America in our Mobility segment and Outdoor Network Solutions business reflects our industry-leading technology, scale and customer relationships.

“We remain committed to identifying and pursuing opportunities to drive solid growth in core and adjacent markets through innovation and accretive acquisitions. We are confident that the continued prudent investment in our business, strategic allocation of capital toward accretive M&A and a focus on operational efficiency will enable us to deliver continued growth and value to shareholders. Our platform of world-class, differentiated solutions and services continues to set CommScope apart.”

Second Quarter 2018 Overview

Sales were in line with expectations and increased 6 percent year over year as growth in the North America and Europe, Middle East and Africa (EMEA) regions more than offset lower sales in the Asia-Pacific region. Foreign exchange rate changes favorably impacted net sales by less than 1 percent.

GAAP operating income in the second quarter of 2018 increased 21 percent year over year to $165 million. Non-GAAP adjusted operating income, which excludes amortization of purchased intangibles, restructuring costs and other special items, increased 4 percent year over year to $251 million, or 20 percent of net sales. The increases in GAAP and non-GAAP adjusted operating income were primarily driven by higher North American sales volumes and cost reduction initiatives. These were partially offset by lower selling prices, higher input costs and the impact of unfavorable foreign exchange rate changes. In addition, GAAP operating income benefited from lower integration and restructuring costs.

Second Quarter 2018 Segment Overview

Second quarter Connectivity Solutions segment sales increased 2 percent year over year to $740 million driven primarily by strength in the EMEA region. Foreign exchange rate changes positively benefited net sales by less than 1 percent.

Connectivity Solutions GAAP operating income increased 15 percent year over year to $85 million largely due to lower integration and restructuring costs. Non-GAAP adjusted operating income decreased 2 percent year over year to $143 million, or 19 percent of segment net sales. Non-GAAP adjusted operating income decreased primarily due to higher input costs, lower selling prices and the impact of unfavorable foreign exchange rate changes. These declines were partially offset by the benefits from cost reduction initiatives and higher sales volumes.

Second quarter Mobility Solutions segment sales increased 11 percent year over year to $499 million driven by double-digit growth in North America coupled with less pronounced increases in Latin America and EMEA. This growth was offset by lower sales in the Asia-Pacific region. Foreign exchange rate changes favorably impacted net sales by approximately 1 percent.

Mobility Solutions GAAP operating income increased 27 percent year over year to $79 million, and non-GAAP adjusted operating income increased 13 percent year over year to $108 million, or 22 percent of segment net sales. Both GAAP and non-GAAP adjusted operating income benefited from higher North American sales volumes partially offset by lower selling prices and the impact of unfavorable foreign exchange rate changes.

Debt Repayment

CommScope has made solid progress identifying new opportunities to accelerate its long-term growth prospects. The company believes that enhancing strategic balance sheet flexibility will provide the best way to support long-term value creation.

As a result, the company will repay $400 million of its term loan on July 31, 2018 by utilizing $250 million of cash on hand and borrowing $150 million under its asset-backed revolving credit facility.

Outlook

CommScope management issued third quarter 2018 guidance and reaffirmed its guidance range for the full year 2018.

Non-GAAP Financial Measures

CommScope management believes that presenting certain non-GAAP financial measures enhances an investor’s understanding of our financial performance. CommScope management further believes that these financial measures are useful in assessing CommScope’s operating performance from period to period by excluding certain items that we believe are not representative of our core business. CommScope management also uses certain of these financial measures for business planning purposes and in measuring CommScope’s performance relative to that of its competitors. CommScope management believes these financial measures are commonly used by investors to evaluate CommScope’s performance and that of its competitors. However, CommScope’s use of the terms non-GAAP adjusted operating income, non-GAAP adjusted EBITDA, non-GAAP adjusted net income and non-GAAP adjusted earnings per share may vary from that of others in its industry. These financial measures should not be considered as alternatives to operating income (loss), net income (loss) or any other performance measures derived in accordance with U.S. GAAP as measures of operating performance, operating cash flows or liquidity.
