NEUSTAR COMPLETES ACQUISITION OF TARGUSINFO

Updates Full-Year 2011 Guidance

STERLING, VA., November 8, 2011 – Neustar, Inc. (NYSE:NSR) today completed its acquisition of Targus Information Corporation, or TARGUSinfo, which was announced on October 11, 2011. Neustar also announced it has updated its full-year 2011 guidance to reflect the completed acquisition.

“We’re pleased to announce that we have completed the acquisition of TARGUSinfo, which broadens the services we offer, accelerates our top-line growth, and creates additional long-term value for our shareholders,” said Lisa Hook, Neustar’s president and chief executive officer. “The integration of our TARGUSinfo unit significantly expands Neustar’s ability to offer a more diverse portfolio of services in the $30 billion real-time information and analytics market, better enabling us to serve our existing customers and new ones.”

TARGUSinfo is a leading provider of real-time, on-demand information services including Caller ID, providing analytics and insights to its customers over 100 billion times a year. TARGUSinfo will become Neustar’s third business segment, along with Carrier and Enterprise Services. The division will be led by Dennis Ainge, former Executive Vice President, corporate development for TARGUSinfo.

Said Ainge, “I am pleased to be joining forces with my colleagues at Neustar and excited about the opportunities to develop and deliver an even broader range of services for our combined client base. We will be focused on leveraging our technology platforms to offer leading-edge solutions to customers and penetrate new high-growth markets.”

Business Outlook

Neustar updated its 2011 guidance previously provided on October 11, 2011 to incorporate the expected results of TARGUSinfo for the remainder of the year. This guidance is based on Neustar’s performance from continuing operations and excludes stock-based compensation, the amortization of acquired intangibles, TARGUSinfo acquisition costs, and tender offer costs. For full-year 2011, the Company expects:

Said Paul Lalljie, Neustar’s chief financial officer, “Our updated guidance for the full-year 2011 reflects a month and a half of TARGUSinfo’s operating activity. To allow investors to properly evaluate operating performance, we have excluded non-cash items such as stock-based compensation and the amortization of intangibles from our earnings guidance. In addition, we have excluded the costs associated with this acquisition and the tender offer to provide a relevant comparison of operating results. We will provide a view of 2012 on our Fourth Quarter and Full-Year 2011 earnings call in February, by which time we will have completed our 2012 planning process as well as a few months as a combined entity.”

Reconciliation of Non-GAAP Financial Measures

In this press release and in other public statements, Neustar presents certain non-GAAP financial data for Neustar. To place this data in an appropriate context, the following is a reconciliation of income from continuing operations to adjusted EBITDA from continuing operations for the year ended December 31, 2010. Also provided is a reconciliation of projected income from continuing operations to projected adjusted EBITDA from continuing operations for the year ending December 31, 2011.

The reconciliation allows investors to appropriately consider each non-GAAP financial measure. These non-GAAP financial measures, however, should not be considered a substitute for or superior to, financial measures calculated in accordance with GAAP, and the financial results calculated in accordance with GAAP and reconciliations from these results should be carefully evaluated. Management believes that these measures enhance investors’ understanding of the Company’s financial performance and the comparability of the Company’s operating results to prior periods, as well as against the performance of other companies. However, these non-GAAP financial measures 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. Prior disclosures of non-GAAP figures do not exclude the same items and as such should not be used for comparison purposes.
