NEW YORK, NY – December 22, 2016 – Syniverse Holdings, Inc. (“Syniverse”) and Syniverse Foreign Holdings Corporation (“SFHC”), an indirect wholly-owned subsidiary of Syniverse, today announced the early tender results for the previously announced offer to exchange (the “Exchange Offer”) for up to $364 million (the “Maximum Exchange Amount”) of Syniverse’s outstanding 9.125% Senior Notes due 2019 (the “Existing Notes”) held by Eligible Holders (as defined below).

As of the previously announced Early Tender Time of 5:00 p.m., New York City time, on December 21, 2016, according to information provided by D.F. King & Co., Inc., the Information and Exchange Agent for the Exchange Offer, $433,507,000 aggregate principal amount (or 91.26% of the outstanding principal amount) of the Existing Notes had been validly tendered and not validly withdrawn in the Exchange Offer. Because Existing Notes in excess of the Maximum Exchange Amount have been validly tendered and not validly withdrawn on or prior to the Early Tender Time, Syniverse will accept Existing Notes validly tendered and not validly withdrawn on or prior to the Early Tender Time on a pro rata basis according to the pro ration procedures described in the Offering Memorandum (as defined below).

The Exchange Offer remains open and is scheduled to expire at midnight, New York City time, on January 6, 2017, unless extended or earlier terminated by SFHC (the “Expiration Time”). Existing Notes that have been tendered or that may be tendered prior to the Expiration Time may not be withdrawn.

The Exchange Offer is being made solely to Eligible Holders upon the terms and subject to the conditions set forth in the confidential offering memorandum (the “Offering Memorandum”) and the related letter of transmittal (the “Letter of Transmittal”), each dated December 8, 2016.

The Exchange Offer is being made only (a) in the United States, to holders of Existing Notes who are “qualified institutional buyers,” as defined in Rule 144A under the Securities Act of 1933 (the “Securities Act”), (b) outside the United States, to holders of Existing Notes who are not “U.S. persons,” as defined in Rule 902 under the Securities Act and (c) to institutional investors which are “accredited investors,” as defined in Rule 501(a)(1), (2), (3), (7) or (8) under the Securities Act. We refer to the holders of Existing Notes who have certified that they are eligible to participate in the Exchange Offer pursuant to at least one of the foregoing conditions as “Eligible Holders.”

Consummation of the Exchange Offer is conditioned upon the satisfaction or waiver of the conditions set forth in the Offering Memorandum and the Letter of Transmittal. In addition, the Exchange Offer may be terminated or withdrawn at any time, in SFHC’s sole and absolute discretion, subject to compliance with applicable law.

The complete terms and conditions of the Exchange Offer are described in the Offering Memorandum and Letter of Transmittal, copies of which may be obtained by Eligible Holders by contacting D.F. King & Co., Inc., the information and exchange agent in connection with the Exchange Offer, at (800) 628-8528 (toll-free) or (212) 269-5550 (Banks and Brokers) or by visiting www.dfking.com/Syniverse to complete the eligibility process. Holders of Existing Notes that are not Eligible Holders will not be able to receive such documents, but Syniverse will make alternative arrangements available to ensure that they can participate, subject to applicable law. Such holders should contact D.F. King & Co., Inc. and will receive information about alternative arrangements available to them.
