SYNCHRONOSS TECHNOLOGIES TO ACQUIRE INTRALINKS HOLDINGS

ACCELERATING STRATEGIC TRANSFORMATION

Press Release:

•Synchronoss to acquire Intralinks Holdings, Inc. for $13.00 per share or $821 million in equity value

•Intralinks will be a major step towards significantly expanding the scale and scope of Synchronoss’ transformation to attack the multi-billion dollar enterprise market opportunity

•Ron Hovsepian, Chief Executive Officer of Intralinks, is expected to be appointed as Chief Executive Officer of Synchronoss upon closing of the transaction with Synchronoss

•Stephen G Waldis, Founder and current Chief Executive Officer, will remain active in the company  serving as Executive Chairman of the Board, driving strategy, product innovation and oversight for the transformation

•Synchronoss to divest a portion of its activation business to Sequential Technology International for $146 million; strategic alternatives being pursued for remaining activation assets

BRIDGEWATER, NJ and NEW YORK, NY — December 6, 2016 - Synchronoss Technologies, Inc. (NASDAQ: SNCR) and Intralinks Holdings, Inc. (NYSE: IL) today announced that they have entered into a definitive agreement for Synchronoss to acquire Intralinks for approximately $821 million in equity value. Under the terms of the agreement, Synchronoss will commence a cash tender offer to acquire all of the outstanding common stock of Intralinks for $13.00 per share.  The transaction, which was unanimously approved by the board of directors of both companies, is expected to close late in the first calendar quarter of 2017, subject to customary closing conditions.  Ron Hovsepian, Chief Executive Officer of Intralinks, is expected to be appointed Chief Executive Officer of Synchronoss and join the Synchronoss Board of Directors upon closing of the transaction with Synchronoss’ Founder and current Chief Executive Officer, Stephen G. Waldis will move into the role of active Executive Chairman of the Board.

In Intralinks’ 20-year history, over 4.1 million business users across the world have used its secure, cloud-based platform, and it counts 99% of Fortune 1000 companies among its customers. To date, Intralinks has supported over $31 trillion in high-stakes transactions, making the company a leader in the enterprise content collaboration market.

“Intralinks has established itself as a household name in the financial services world over the past 20 years, with a keen focus on growing its presence into the next generation secure content collaboration market over the coming years,” said Stephen Waldis, Synchronoss’ CEO.  “This acquisition marks another major step in the transformation of Synchronoss to significantly expand the scale and scope of the company’s enterprise initiatives and strong carrier relationships in attacking this multi-billion dollar market opportunity. Ron brings significant leadership experience and a history of successfully integrating companies into a single portfolio.  I intend to stay active in the company, driving growth opportunities and continued developments on new product innovation. I am excited to be working closely with Ron to bring Synchronoss into its next chapter of growth”.

“Our board of directors unanimously concluded that Synchronoss is the ideal strategic partner for Intralinks and also gives our employees and customers the opportunity to leverage Synchronoss’ deep relationships across the carrier space, cloud expertise, and strong partnerships in the financial  services vertical,” said Ron Hovsepian, CEO of Intralinks. “Together with Synchronoss, we believe we can deploy enhanced enterprise and mobile solutions to our customers while opening up new enterprise distribution channels across the world.”

In conjunction with today’s announcement Synchronoss is also announcing an agreement to divest a portion of its activation business to Sequential Technology International, LLC for a total purchase price of $146 million.  As part of this transaction, Sequential Technology will purchase 70% of Synchronoss’ carrier activation business that is being divested, with Synchronoss retaining a 30% ownership piece which could be reduced during the course of 2017.  Synchronoss is in the process of pursuing strategic alternatives for the remaining activation business assets.

Synchronoss expects to finance the Intralinks acquisition with its existing cash, proceeds from the Sequential Technology transaction, and $900 million of new debt.

Given the expected closing in the first calendar quarter of 2017, Synchronoss expects the Intralinks transaction to have no impact to its fourth quarter financials.  With the impact from the Sequential Technology divestiture and assuming a late first quarter 2017 close on the Intralinks deal, Synchronoss is giving initial 2017 revenue guidance of between $810 million and $820 million with pro forma EPS of between $2.45 and $2.60 for the combined entity.  We are targeting $40 million of combined synergies within the first year of closing the Intralinks deal.

The Intralinks transaction is subject to the satisfaction of customary closing conditions, including regulatory approval in the United States. Until the transaction closes, each company will continue to operate independently.

PJT Partners is serving as lead financial advisor. Goldman Sachs & Co. and Credit Suisse are providing debt financing commitments to Synchronoss and Goldman Sachs & Co. is also serving as financial advisor to Synchronoss.   J.P. Morgan Securities LLC is serving as a financial advisor to Intralinks.  Gunderson Dettmer Stough Villeneuve Franklin & Hachigian, LLP is acting as legal advisor to Synchronoss in connection with the Intralinks acquisition, and Simpson Thacher & Bartlett LLP is acting as legal advisor in connection with the debt financing to Synchronoss.  Skadden, Arps, Slate, Meagher & Flom, LLP is acting as legal advisor to Intralinks in connection with the acquisition.

Exhibit 99.2

Team,

We announced this morning that Intralinks is being acquired by Synchronoss Technologies, Inc. (NASDAQ: SNCR), a global leader in secure, managed mobility solutions for service providers and enterprises. I am very pleased with this acquisition, not only because it is a great opportunity to accelerate our growth, but also because it is a testament to our world-class technology and people. Please join me at 10:00am EST for an All Hands call when I will provide additional details.

In the meantime, here is why I believe that Synchronoss is the ideal strategic partner for Intralinks. Synchronoss brings to our market powerful secure mobility and identity platforms, as well as major enterprise partners such as Goldman Sachs and Verizon. By integrating Synchronoss’ leading mobile capabilities with Intralinks’ content collaboration platform, the combined company will be well positioned for the exciting market opportunities we see ahead of us.

I am very excited about this acquisition, and the scale, infrastructure and technology we will now be able to leverage. We are being acquired for our technology, customers, and the domain expertise of our people. As we integrate these two world-class companies, we should all look to each other and the new colleagues we will gain and harness this opportunity to accelerate our collective success.

You should receive a calendar invite soon, and I look forward to speaking with all of you on the All Hands call. In addition to a conference bridge, we have set up conference rooms in major offices for this call.

Sincerely,

Ron Hovsepian
