Neustar Reports Results for Third Quarter 2011

Board Authorizes an Additional $250 Million Share Repurchase

STERLING, VA., October 11, 2011 — Neustar, Inc. (NYSE: NSR), a global leader in network addressing, routing and policy management, today announced results for the quarter ended September 30, 2011. The company also increased its guidance for full-year 2011 and announced the repurchase of up to $250 million of its Class A common shares on an accelerated basis.

In a separate announcement, the company stated that it has entered into a definitive agreement to acquire Targus Information Corporation, or TARGUSinfo, a leading, independent provider of real-time, on-demand information and analytics services including Caller ID, for approximately $650 million in cash.

Summary of Consolidated Third Quarter Results Compared to Third Quarter of 2010

“Neustar continues to drive shareholder value across multiple fronts. Our third quarter results demonstrate our ability to continue to deliver double-digit revenue growth and generate strong profits and cash flows,” said Lisa Hook, Neustar’s president and chief executive officer. Ms. Hook continued, “The acquisition of TARGUSinfo furthers our business strategy with growing, high margin operations in markets adjacent to our core business. Our new capital structure, including a prudent amount of debt, allows us to make this acquisition and continue significant returns to shareholders. We are building shareholder value by increasing future cash generation and strategically diversifying our business while accelerating our share repurchases.”

Paul Lalljie, Neustar’s chief financial officer added, “We continue to deliver strong top line growth coupled with high margins and cash flows. This allows us to invest organically, make strategic, accretive acquisitions and return meaningful amounts of capital to shareholders. The third quarter results and the key performance indicators of our business have prompted us to update our full-year revenue and EBITDA guidance. Strong financial momentum, coupled with our operational achievements, put us in a solid position for growth in the future.”

Discussion of Third Quarter Results

Consolidated revenue totaled $152.5 million, an 18% increase from $129.4 million in the third quarter of 2010, driven by growth in both the Carrier Services and Enterprise Services business segments. In particular:

Total operating expense increased 24% to $94.4 million from $76.1 million in the third quarter of 2010. The $18.3 million year-over-year increase includes approximately $6 million in operating expenses from acquired businesses, and approximately $2 million of deal related expenses. The remaining $10.3 million increase in operating expenses was driven by increased personnel and personnel-related expenses and royalties to support increased revenues and operations.

Results related to the company’s Converged Messaging Services business for prior periods have been reclassified to discontinued operations following the company’s exit of its Converged Messaging Services business during the second quarter of 2011.

Cash, cash equivalents and investments totaled $410.3 million as of September 30, 2011, compared to $432.1 million as of June 30, 2011 and compared to $382.4 million as of December 31, 2010. The net decrease in cash, cash equivalents, and investments from the quarter ended June 30, 2011 of $21.8 million was primarily due to the purchase of certain numbering solutions assets from Evolving Systems, Inc. for approximately $39 million. The company also purchased approximately 941,000 shares of its Class A common stock at an average price of $25.10 per share, for a total purchase price of $23.6 million.

Business Outlook for 2011

The company updated the full-year 2011 guidance previously provided on July 27, 2011:

Reconciliation of Non-GAAP Financial Measures

In this press release and in other public statements, Neustar presents certain non-GAAP financial data. To place this data in an appropriate context, the following is a reconciliation of income from continuing operations to EBITDA from continuing operations for the three and nine months ended September 30, 2010 and 2011 and the year ended December 31, 2010. Also provided is a reconciliation of projected income from continuing operations to projected 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.

Reconciliation to EBITDA from continuing operations
