Q1 2017 Update and Withdrawal of FY 2017 Guidance As previously disclosed, Synchronoss expects total revenue for the first quarter of 2017 to be $13 million to $14 million less than the company's previously announced guidance Operating margins expected to be 8% - 10%, which is lower than previously announced guidance of 18% - 20% Synchronoss has not lost any material customers The primary driver of the lower revenue in the quarter was a new incremental enterprise license opportunity with a core carrier customer that did not materialize in the quarter as expected. This license miss combined with a delay in our cost reduction plan also impacted profitability in Q1 Despite an overall uptick in deal activity in Intralinks’ M&A business, Q1 revenues from Intralinks were softer as a result of smaller average deal sizes Our previous 2017 annual guidance is withdrawn and new guidance cannot be provided until we have completed our accounting review and our assessment of the revenue impact on future financial periods including the timing and performance of certain other incremental programs that were previously forecasted for 2017. The combination of these items will have a negative impact on our 2017 financial results as compared to our previously issued 2017 guidance We are working diligently to complete the accounting restatement and will provide revised guidance when we report our Q1 results along with our restated financial statements for 2015 and 2016

June 2017 Reorganization Initiative per Filed 8-K On June 14, 2017 Synchronoss commenced a management streamlining and realignment plan (the “Plan”) The Plan, together with the management changes previously announced, is expected to realize approximately $70 million of annualized pre-tax expense savings per our filed 8-K on June 20, 2017 These expected savings are in addition to the approximate $20 million of annual pre-tax expense synergies the Company previously realized in connection with its acquisition and integration of Intralinks In addition, Synchronoss has prudently eliminated and streamlined other cost initiatives across the company for 2017 to better align our expense profile with a more recurring based revenue trajectory As a result of the Plan, the Company currently estimates that it will recognize a pre-tax charge of approximately between $22 million and $25 million, which consists of severance payments and other termination costs with cash expenditures This reorganization initiative was structured for minimal revenue disruption while optimizing efficiencies and cash flow generation
