Nasdaq Compliance and Common Stock The Notice, as discussed in Note 9 - Stockholder’s Equity sub-section, “Subsequent Events - Nasdaq Compliance and Common Stock” indicated that the Company had until July 17, 2017 to submit a plan to regain compliance with Nasdaq’s continued listing requirements. On July 17, 2017, the Company timely submitted its plan to Nasdaq detailing how the Company plans to regain compliance with Nasdaq’s continued listing requirements (the “Compliance Plan”). Nasdaq accepted the Compliance Plan and granted the Company an extension of up to 180 calendar days from the Form 10-Q’s due date, or until November 6, 2017, to regain compliance. On July 26, 2017, the Nasdaq granted the Company an exception from its continued listing requirements until November 13, 2017 to file all delinquent periodic reports, including its delinquent Quarterly Report on Form 10-Q for the period ended March 31, 2017. In connection with its delinquency in filing its Quarterly Report on Form 10-Q for the period ended June 30, 2017, Nasdaq has requested an update to the Company’s original plan to regain compliance with Nasdaq’s continued listing requirements. On August 16, 2017, the Company received notice from the Nasdaq indicating that the Company was not in compliance with the Rule because the Company has not yet filed its Quarterly Report on Form 10-Q for the period ended June 30, 2017. On November 15, 2017, the Company received a letter from the Staff of the Nasdaq notifying the Company that since it remains delinquent in filing its Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2017, June 30, 2017 and September 30, 2017, it has not regained compliance with the Rule, which requires timely filing of periodic reports with the Securities and Exchange Commission (the “SEC”). Previously, Nasdaq granted the Company an extension until November 13, 2017 to file all delinquent periodic reports. As described in the letter, as a result of the continued delinquency, the Company’s common stock is subject to delisting unless the Company timely requests a hearing before a Nasdaq Hearings Panel (the “Panel”). On December 6, 2017 the Company received a letter from the Hearings Department of the Nasdaq granting the Company’s request to extend the stay of suspension pending a hearing before the Panel, in late January 2018, and issuance of a final Panel decision. On February 6, 2018, the Company received a notification letter from a Hearings Advisor from the Nasdaq Office of General Counsel informing the Company that the Panel granted the Company’s request for an extension until May 10, 2018 to become current with its filings with the SEC. Additionally, the extension was subject to the Company providing the Panel with periodic updates regarding its ongoing restatement of its financial statements and providing the Panel with an update issued to investors on or before March 31, 2018. The Panel granted the Company the maximum possible extension until the expiration of the Panel’s discretion to allow continued listing while the Company remained out of compliance with Nasdaq’s continued listing requirements. To comply with the Nasdaq extension requirements, the Company issued an update to investors on March 28, 2018. On May 4, 2018, the Company informed the Panel of its determination that it would be unable to satisfy the May 10, 2018 deadline. On May 11, 2018, the Company received a notification letter from the Panel indicating that trading in the Company’s common stock was suspended effective at the open of business on May 14, 2018. The Panel also determined to delist the Company’s shares from Nasdaq after applicable appeal periods have lapsed. The Company has appealed the decision to the Nasdaq Listing and Hearing Review Council. During the appeal process, the Company’s stock remains listed however trading in the Company’s common stock on Nasdaq remains suspended. While the Company’s common stock is suspended from trading on Nasdaq, the Company’s shares are currently quoted on the OTC Markets under the trading symbol SNCR. Share Purchase Agreement See Note 9 - Stockholder’s Equity sub-section “Subsequent Event - Share Purchase Agreement” for a description of subsequent events regarding the Share Purchase Agreement that resulted in the Intralinks divestiture during 2017. Shares of Preferred Stock See Note 9 - Stockholder’s Equity sub-section “Subsequent Events - Shares of Preferred Stock” for a description of the terms of the PIPE Purchase Agreement with Silver on February 15, 2018, in which the Company issued Series A Preferred Stock. Acquisition of honeybee In May 2018, the Company completed the acquisition of the honeybee software business, a provider of digital solutions targeted at optimizing the customer experience from Dixons Carphone plc. honeybee offers a digital transformation platform that makes it easier for companies to design and launch omni-channel customer journeys. The Company paid cash consideration of approximately $10.7 million. Customers of the honeybee platform, such as mobile operators and other communication service providers, can rapidly create and adapt digital sales processes for contact centers, retail stores, and online channels. This reduces complexity for the end-user as well as internal employees, while delivering a single customer experience at all touch-points and improved business outcomes such as reduced cost and increased revenue. 2019 Notes Notice On June 13, 2018, The Bank of New York Mellon, in its capacity as trustee (the “Trustee”) under the indenture dated as of August 12, 2014 (the “Indenture”) governing the Company’s 0.75% Convertible Senior Notes due in 2019 (the “2019 Notes”), filed a verified complaint with the Court of Chancery of the State of Delaware, captioned The Bank of New York Mellon, as Indenture Trustee v. Synchronoss Technologies, Inc. (the “BNY Action”). The BNY Action complaint alleges that as a result of our common stock ceasing to be listed or quoted on Nasdaq and that an Event of Default under the Indenture has occurred as a result of our failure to provide a notice of such Fundamental Change, which, if true, following notice from holders of more than 25% of the outstanding principal under the Notes would trigger the acceleration of the principal and interest outstanding under the 2019 Notes. The complaint seeks a declaratory judgment that (i) a Fundamental Change occurred, (ii) the Company improperly failed to issue a Fundamental Change Company Notice (as defined in the Indenture), (iii) an Event of Default has occurred (as defined in the Indenture), (iv) the Notes have been accelerated, (v) outstanding principal and outstanding unpaid interest on the Notes became immediately due and payable as of June 11, 2018 and (vi) post-judgment interest shall accrue at the statutory rate from the date of declaratory judgment. The Company does not believe that a Fundamental Change has occurred under the Indenture. Therefore, the Company does not believe that any Event of Default, as defined in the Indenture, has occurred or is continuing and does not believe that the Trustee or any holders have a right to declare obligations under the Indenture due and payable. As such, the Company believes that the asserted claims lack merit, and the Company intends to defend against all of the claims vigorously. Due to the inherent uncertainties of litigation, the Company cannot predict the outcome of the BNY Action at this time, and the Company can give no assurance that the asserted claims will not have a material adverse effect on the Company’s financial position or results of operations.
