Neustar Reports Results for First Quarter 2016

STERLING, VA, April 28, 2016— Neustar, Inc. (NYSE: NSR), a trusted, neutral provider of real-time information services, today announced results for the quarter ended March 31, 2016, and updated its guidance for full-year 2016.

Results for First Quarter 2016 Compared to First Quarter 2015

• Revenue increased 14% to $287.3 million

• Marketing Services revenue increased 55% to $57.7 million

• Security Services revenue increased 23% to $48.6 million

• Net income of $31.4 million or $0.57 per share

Non-GAAP Results for First Quarter 2016 Compared to First Quarter 2015

• Adjusted EBITDA of $119.7 million or a margin of 42%

• Adjusted net income of $58.4 million or $1.06 per share

“Once again, our Information Services delivered strong organic revenue growth, led by 25% in Marketing Services and 10% in Security Services. And after owning MarketShare for a full quarter, we are even more confident in the strategic fit of this acquisition,” said Lisa Hook, Neustar’s President and Chief Executive Officer. “It is clear that the combination of our teams, powerful analytics and unique authoritative identity framework positions us favorably to capitalize on tremendous opportunities and drive shareholder value. The power of the combination is demonstrated by recent customer wins such as Audi UK, Deutsche Telecom and Angie's List. Long-term prospects remain strong, although near-term integration-related factors contributed to our revised view of 2016 revenue expectations.”

Paul Lalljie, Neustar’s Chief Financial Officer, added, “Information Services continued to build on its momentum from last year, generating 9% organic revenue growth for the quarter. In addition to strong organic results, the combined revenue for the quarter from our 2015 acquisitions reflected double-digit revenue growth as compared with their combined revenue for their first quarter of 2015.  For 2016, our capital allocation strategy will focus on using the majority of our free cash flow to pay down debt, and our recent prepayment of $25 million demonstrates our commitment to this strategy.”

Discussion of First Quarter Results

Neustar's year-over-year quarterly revenue growth of 14% was driven primarily by strong demand for our Marketing Services and our Security Services. In particular, Marketing Services revenue grew 25% organically and included $11.3 million from MarketShare. Security Services revenue grew 10% organically and included $4.9 million from Bombora. Data Services revenue declined 7% when adjusted for the $9.2 million decrease in revenue from the expiration of the common short codes contract in 2015 and the contribution of $16.9 million from the TNS assets.

Comparing first quarter 2016 results to the corresponding period in 2015:

• Revenue from Marketing Services increased 55% to $57.7 million driven by increased demand for Neustar's services that help its clients make high-impact decisions to promote and protect their businesses.

• Revenue from Security Services increased 23% to $48.6 million driven by an increase in domain names under management, and an increase in demand for Neustar's DNS Services, particularly its DDoS mitigation services.

• Revenue from Data Services increased 10% to $53.2 million driven by revenue from the acquisition of the TNS assets partially offset by a $9.2 million decrease in revenue driven by the expiration of the common short codes contract in 2015.

• Revenue from NPAC Services increased 1% to $127.8 million driven by statements of work under Neustar's contracts to provide local number portability services.

Total operating expense for the first quarter of 2016 increased 30% to $222.9 million from $171.9 million in the first quarter of 2015. This $51.0 million increase was attributable primarily to operational expenses associated with businesses acquired in 2015.

Neustar ended the quarter with cash and cash equivalents of $69.8 million compared to $89.1 million as of December 31, 2015, and $358.4 million as of September 30, 2015. Neustar's outstanding debt under its term facilities and senior notes was $1.1 billion as of March 31, 2016. Additionally, Neustar paid $52 million of principal under its term loan facility, including a $25 million voluntary prepayment of principal after the quarter ended.

Business Outlook for 2016

Neustar updated its guidance to reflect a lower contribution from its recent acquisition of MarketShare, which was partially offset by stronger than expected organic Information Services revenue performance.  All of the measures used by Neustar for guidance assume that it will remain the local number portability administrator for 2016.

• Revenue to range between $1.22 billion to $1.24 billion or growth of 16% to 18% with a midpoint of $1.23 billion; previous revenue guidance range of $1.22 billion to $1.26 billion with a midpoint of $1.24 billion

• Information Services revenue to range between $715 million to $735 million or growth of 32% to 35% with a midpoint of $725 million; previous revenue guidance range of $715 million to $755 million with a midpoint of $735 million

• Adjusted EBITDA to range between $555 million to $565 million or a margin of 45% to 46% with a midpoint of $560 million; previous adjusted EBITDA guidance range of $555 million to $575 million with a midpoint of $565 million

• Adjusted net income range to remain between $278 million to $298 million or a margin of 23% to 24% with a midpoint of $288 million

• Adjusted net income per share range to remain between $5.03 to $5.39 or growth of 6% to 13% with a midpoint of $5.21

Reconciliation of Non-GAAP Financial Measures

In this press release and in other statements, Neustar presents certain non-GAAP financial measures. These non-GAAP financial measures have limitations and may not be comparable with similar non-GAAP financial measures used by other companies and should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Set forth below are reconciliations of the non-GAAP financial measures to their most directly comparable GAAP financial measures. These reconciliations should be carefully evaluated. Prior disclosures of non-GAAP figures may not exclude the same items and as such should not be used for comparison purposes.

Reconciliation of Net Income to Adjusted Net Income and Adjusted EBITDA

The following tables reconcile net income to adjusted net income and adjusted EBITDA, respectively, for the three months ended March 31, 2015 and 2016 and the year ending December 31, 2016. Management believes that these measures enhance investors’ understanding of the company’s financial performance and the comparability of the company’s results to prior periods, as well as against the performance of other companies.
