NeuStar named ``2005 IPO of the Year'' by Renaissance Capital.

GREENWICH, Conn. -- NeuStar (NSR), a clearinghouse for the North American communications industry, was named the "2005 IPO of the Year" by the IPO research committee at Renaissance Capital. The Sterling, VA-based communications company was chosen from a field of 191 companies that went public during 2005, based on a study conducted by Renaissance Capital's analysts who prepared an investment research report on each firm. NeuStar was chosen as the "2005 IPO of the Year" on the basis of its impressive track record of high profitability, commanding competitive position in the communications industry, compelling growth trajectory, solid governance and the strong performance of the company's stock since its IPO.

NeuStar was taken public by lead managers Morgan Stanley, Credit Suisse First Boston and JPMorgan on June 29, 2005 and became the 9th largest IPO of the year, raising $605 million in gross proceeds. NeuStar's stock rose 18% to $26 on its first day of trading, and gained additional momentum in the aftermarket leading to an overall return of 44% from its offer price. NeuStar's business is predicated on providing essential clearinghouse services, such as number administration, network reconfiguration and inter-network compatibility, to virtually every North American communications provider predominately through exclusive, long-term contracts. The company's operations are benefiting from major trends that are unfolding in the communications industry, including the ongoing consolidation of wireless communications providers and the emergence of voice-over-IP (VoIP) services.

"While there were a number of strong candidates among this year's crop of IPOs, NeuStar distinguished itself because of its impressive financial track record, robust prospects for growth, seasoned management team and sound corporate governance practices. These are qualities that we look for in a great IPO." said William K. Smith, President of Renaissance Capital.

Companies receiving Honorable Mention for "2005 IPO of the Year" were Adams Respiratory Therapeutics (ARXT), a specialty pharmaceutical company marketing cough suppressants under the "Mucinex" brand, Chicago Board of Trade (BOT), the world's third largest derivatives exchange, and Zumiez (ZUMZ), a high-growth specialty retailer of action sports apparel and equipment.
