CommScope Reports First Quarter 2015 Results

First Quarter Adjusted EPS of $0.42 Exceeds Guidance

HICKORY, NC, April 30, 2015—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 $825 million and net income of $39 million, or $0.20 per diluted share for the quarter ended March 31, 2015. Non-GAAP adjusted net income for the first quarter of 2015 was $81 million, or $0.42 per diluted share. A reconciliation of reported GAAP results to non-GAAP results is attached.

For the quarter ended March 31, 2014, CommScope reported sales of $935 million and net income of $64 million or $0.34 per diluted share. Non-GAAP adjusted net income for the first quarter of 2014 was $95 million, or $0.50 per diluted share.

“CommScope delivered solid first quarter performance and exceeded earnings per share guidance despite a slow start in North American wireless carrier spending and foreign exchange headwinds,” said President and Chief Executive Officer Eddie Edwards. “We are pleased with the revenue growth and margin expansion of our Enterprise and Broadband segments this quarter. We continue to believe wireless carrier spending will strengthen as we move into the second half of the year.”

On January 28, 2015, CommScope announced an agreement to acquire TE Connectivity’s Telecom, Enterprise and Wireless businesses. This business is a global leader in fiber optic connectivity for wireline and wireless networks, and the transaction is expected to be in excess of 20 percent accretive to CommScope’s adjusted earnings per share by the end of the first full year after closing, excluding purchase accounting charges, integration costs and other special items.

“We continue to believe that the ever increasing global demand for broadband connectivity and our planned transformative acquisition of TE Connectivity’s Telecom, Enterprise and Wireless businesses will position CommScope well for long-term growth and value creation,” Edwards said. “Given the secular demand for fiber, TE Connectivity’s fiber portfolio is expected to be a driver of growth across CommScope’s businesses. We look forward to bringing our businesses together later this year and quickly realizing the benefits of this important transaction.”

First Quarter 2015 Overview

First quarter 2015 sales declined 12 percent year over year to $825 million. Growth in the Enterprise and Broadband segments was offset by lower North American Wireless sales. Foreign exchange rate changes negatively affected sales by 3 percent in the quarter compared to the prior year period.

Operating income in the first quarter declined 36 percent to $93 million, compared to $147 million in the same period last year. Adjusted operating income, which excludes amortization of purchased intangibles, restructuring costs and other special items, declined 18 percent year over year to $156 million.

GAAP net income decreased 39 percent year over year to $39 million. Excluding amortization of purchased intangibles, restructuring costs and other special items, first quarter adjusted net income decreased 14 percent year over year to $81 million. Adjusted earnings were $0.42 per diluted share, down 16 percent year over year.

First Quarter 2015 Segment Overview

Wireless segment sales in the first quarter were $496 million, a year-over-year decline of 21 percent, primarily due to a slowdown in spending by certain North American wireless operators, which was partially offset by growth in the Asia Pacific and Central and Latin America regions. Additionally, foreign exchange rate changes had a negative impact of approximately 4 percent on Wireless segment sales in the first quarter compared to the prior year period. The company’s acquisition of two businesses of United Kingdom-based Alifabs Group, completed in July 2014, provided incremental net sales to the Wireless segment of $11 million during the first quarter of 2015. Wireless adjusted operating income was $98 million for the quarter, down 36 percent year over year, primarily due to lower sales.

First quarter Enterprise segment sales increased 5 percent year over year to $211 million. The increase was primarily driven by strong sales of data center fiber solutions and growth in all major geographic regions. Foreign exchange rates had a negative impact of approximately 1 percent on Enterprise segment sales in the first quarter of 2015 compared to the prior year period. Enterprise adjusted operating income for the quarter increased 36 percent year over year to $49 million, or 23 percent of sales, primarily due to higher sales, lower materials costs and a favorable mix of products sold.

First quarter Broadband segment sales increased 10 percent year over year to $118 million. The growth was primarily driven by increased investment in North America as cable operators continue to expand fiber technology further into their networks and invest to enhance the quality of video and broadband offerings. Broadband sales in the first quarter were also higher in the Central and Latin American region compared to the prior year period. Foreign exchange rates had a negative impact of approximately 1 percent on Broadband segment sales in the first quarter of 2015 compared to the prior year period. Broadband adjusted operating income improved to $9 million, or 8 percent of sales. The increase was driven by higher sales and the benefits from ongoing cost reduction initiatives.

Update on Proposed TE Connectivity Transaction

CommScope has been informed that the Federal Trade Commission and the Antitrust Division of the U.S. Department of Justice have granted early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, in connection with the agreement to acquire TE Connectivity’s Telecom, Enterprise and Wireless businesses. The company is still in the midst of the anti-trust regulatory process in numerous other jurisdictions around the world.

CommScope continues to expect that the transaction will close by the end of this year, subject to contemplated financing, regulatory approvals and other customary closing conditions.

Outlook

CommScope management provided the following second quarter guidance, which excludes the impact of the planned acquisition, amortization of purchased intangibles, restructuring costs, transaction and integration costs and other special items.

Second Quarter 2015 Guidance:

CommScope reaffirmed its full year 2015 earnings guidance of $1.95 to $2.05 per diluted share. The company believes its previously announced 2015 earnings guidance remains achievable, assuming a near-term return to normal spending patterns by North American wireless carriers.

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.
