The deal has been approved by Neustar’s board of directors and its shareholders will receive $33.50 per share in cash – a 45% premium on its closing stock price on 11 November 2016.

Lisa Hook, Neustar’s president and chief executive officer, said: “We believe this transaction will enable us to continue to execute against our strategy and strengthen our market position as a leader in marketing, risk, security and communication solutions.

 “Golden Gate Capital and GIC offered us a compelling opportunity to continue to invest and pursue long-term growth with operational flexibility, and we look forward to working with these two sophisticated investors. Importantly, customers, employees and partners will continue to benefit as we execute against our strategy.”

The transaction, which should close no later than the end of Q3 2017, is subject to approval by Neustar’s shareholders, regulatory approvals and other customary closing conditions.
