Pareteum Enters into Definitive Agreement to Acquire iPass

November 12, 2018

All stock transaction creates significant shareholder value through powerful combination

Generates an anticipated $15 million in annual cost synergies with greater than $12 million expected to be realized in the first full quarter of combined operations

NEW YORK and REDWOOD SHORES, Calif., Nov. 12, 2018  /PRNewswire/ — Pareteum Corporation (TEUM}, a cloud software platform company, and iPass, Inc. (IPAS), a provider of global mobile connectivity, and location and performance data, today announced that they have entered into a definitive agreement under which Pareteum will acquire iPass in an all-stock transaction whereby iPass shareholders will receive 1.17 shares of Pareteum common stock in an exchange offer.

With this accretive acquisition, Pareteum expects to gain a strategic position with new marquee brands and new markets including the enterprise, airline, hospitality, retail and internet of things (IoT) sectors. Pareteum expects to strengthen its established intellectual property portfolio with the addition of over 40 U.S. and international patents. With more than 500 expected new customers and a global network of over 68 million Wi-Fi hot spots, coupled with proven connection management technology, location services and Wi-Fi performance data, Pareteum is now poised to take its global communications software solutions to every market vertical.

Founder, Executive Chairman and Principal Executive Officer of Pareteum Hal Turner said, “iPass and Pareteum will now accelerate as one company with combined products and services, the expansion of addressable markets and the resulting executive and operating talent. It has been a pleasure to work with iPass President and CEO Gary Griffiths to combine our companies and execute on a shared vision for growth.”

“Pareteum has enjoyed a solid partnership with iPass over the past year and our mutual view on connectivity and mobile enablement made it easy to see that we could grow our business and accelerate our mission together,” said Pareteum President Denis McCarthy, who is leading the acquisition. “Our integration with iPass extends not only Pareteum’s customer base, but also our portfolio of services. Customers will now be able to use the Pareteum Global Software Defined Cloud to access premium wireless and Wi-Fi services, and experience location data analytics for a truly immersive experience.”

Gary Griffiths added, “By joining with Pareteum, our vision for iPass SmartConnect is amplified and expanded. Pareteum is one of the fastest growing companies in this industry, and we believe that the combination of our teams, technologies and products will materially

accelerate revenue growth and earnings. Being part of Pareteum’s constellation is exciting, and clearly in the best interest of iPass shareholders, customers, business partners and employees.”

The transaction is expected to be immediately accretive to Pareteum’s non-GAAP EPS and free cash flow after anticipated synergies. Pareteum anticipates achieving more than $15 million in annual cost synergies with greater than $12 million of those expected to be realized in the first full quarter of combined operations. Pareteum currently estimates approximately $2.0 million of GAAP earnings accretion and $5.5 million of non-GAAP earnings accretion in the first full year after closing the transaction. In addition, the acquisition will add new offices and talent in Silicon Valley, California and Bangalore, India, expanding Pareteum’s presence globally.

Under the terms of the definitive acquisition agreement, a wholly-owned subsidiary of Pareteum will commence an exchange offer to acquire all of the outstanding shares of iPass common stock, offering 1.17 shares of Pareteum common stock in exchange for each share of iPass common stock tendered. Upon satisfaction of the conditions to the exchange offer, and after the shares tendered in the exchange offer are accepted for payment, the agreement provides for the parties to effect, as promptly as practicable, a merger, which would not require a vote by iPass stockholders, and which would result in each share of iPass common stock not tendered in the exchange offer being converted into the right to receive 1.17 shares of Pareteum common stock. The exchange offer is subject to customary conditions, including the tender of at least a majority of the outstanding shares of iPass common stock and certain regulatory approvals, and is expected to close in the first quarter of calendar year 2019. No approval of the stockholders of Pareteum is required in connection with the proposed transaction. Terms of the agreement were approved by the board of directors for both Pareteum and iPass.

Jefferies LLC is acting as exclusive financial advisor to Pareteum, along with Sichenzia Ross Ference LLP, which is serving as its legal counsel.

Raymond James & Associates, Inc. is acting as financial advisor to iPass and Cooley LLP is acting as its legal counsel.
