Neustar Resumes Share Repurchase Program

Neustar, Inc.

announced today that it will resume its three-year share repurchase program to purchase up to $300 million in value of its Class A common shares. The Company previously announced on July 28, 2010 that its Board of Directors authorized the share repurchase program, which expires on July 28, 2013. As part of this program, the Company has already repurchased approximately 4.4 million shares of stock at a total cost of $114.7 million through a 10b5-1 plan. This 10b5-1 plan was automatically terminated when the Company announced its $250 million modified “Dutch auction” tender offer, which was completed on December 8, 2011. The remaining authorized amount under the Company's share repurchase program is approximately $185.2 million. Share repurchases may be made through 10b5-1 plans, open market purchases, privately negotiated transactions or otherwise as market conditions warrant, at prices the Company deems appropriate, and subject to applicable legal requirements and other factors.
