Syniverse Terminates Shareholder Rights Plan

Syniverse Holdings, Inc. (NYSE:SVR), a leading provider of technology and business solutions for the global telecommunications industry, today announced that its Board of Directors has approved and adopted an amendment to Syniverse’s shareholder rights plan to accelerate the expiration of the company’s preferred share purchase rights. As a result of the amendment, the shareholder rights plan has terminated effective as of the close of business on July 30, 2010.

The shareholder rights plan was adopted in November 2008 after a decline in the market price of Syniverse’s common stock to ensure that all Syniverse shareholders were treated fairly in the event of any unsolicited takeover of the company. In light of the returned stability and orderly trading in the company’s common stock, and in an effort to more closely align the company’s corporate governance policies with current trends and best practices, the Board of Directors determined it is no longer necessary or in the best interests of the company or its shareholders to maintain the shareholder rights plan.

The decision to terminate the rights plan was not made in connection with any pending business transaction. Syniverse’s shareholders do not need to take any action in connection with the termination of the shareholder rights plan.
