(“Vivint”), until January 17, 2020. The only proposal submitted to a vote of the stockholders was the approval of the adjournment of the Special Meeting to a later date or dates. The adjournment proposal is described in detail in Mosaic’s definitive proxy statement/consent solicitation statement/prospectus filed with the U.S. Securities and Exchange Commission (the “SEC”) and mailed to stockholders on December 27, 2019.

A total of 36,867,996 shares of Common Stock, representing approximately 85.49% of the outstanding shares of Common Stock entitled to vote, were present in person or by proxy, constituting a quorum.

The information included in Item 5.07 of this Current Report on Form 8-K is hereby incorporated by reference into this Item 8.01.

IMPORTANT ADDITIONAL INFORMATION AND WHERE TO FIND IT

This communication is being made in respect of the proposed merger transaction involving Mosaic and Vivint. Mosaic filed a registration statement on Form S-4 (as amended, the “Registration Statement”) with the SEC, which includes a proxy statement of Mosaic, a consent solicitation statement of Vivint and a prospectus of Mosaic, and each party will file or has filed other documents with the SEC regarding the proposed transaction. Beginning on December 3, 2019, a definitive proxy statement/consent solicitation statement/prospectus was sent to the stockholders of Mosaic and Vivint. As a result of amendments made to the proposed merger transaction on December 18, 2019, Mosaic filed post-effective amendments to the Registration Statement, which include an updated proxy statement/consent solicitation statement/prospectus. Beginning on December 27, 2019, an updated definitive proxy statement/consent solicitation/prospectus was sent to the stockholders of Mosaic and Vivint, seeking any required stockholder approval. Before making any voting or investment decision, investors and security holders of Mosaic and Vivint are urged to carefully read the entire Registration Statement and proxy statement/consent solicitation statement/prospectus, including any post-effective amendments or updates thereto, and any other relevant documents filed with the SEC, as well as any amendments or supplements to these documents, because they contain important information about the proposed transaction. The documents filed by Mosaic with the SEC may be obtained free of charge at the SEC’s website at www.sec.gov. In addition, the documents filed by Mosaic may be obtained free of charge from Mosaic at www.mosaicac.com.

FORWARD-LOOKING STATEMENTS

This communication contains, and oral statements made from time to time by our representatives may contain, forward-looking statements including, but not limited to, Mosaic’s and Vivint’s expectations or predictions of future conditions. Forward-looking statements are inherently subject to risks, uncertainties and assumptions. Generally, statements that are not historical facts, including statements concerning our possible or assumed future actions, business strategies, events or results of operations, are forward-looking statements. These statements may be preceded by, followed by or include the words “believes,” “estimates,” “expects,” “projects,” “forecasts,” “may,” “will,” “should,” “seeks,” “plans,” “scheduled,” “anticipates” or “intends” or similar expressions. Such forward-looking statements involve risks and uncertainties that may cause actual events, results or performance to differ materially from those indicated by such statements. Certain of these risks are identified and discussed in Mosaic’s Registration Statement on Form S-4 under “Risk Factors” and Form 10-K for the year ended December 31, 2018 under “Risk Factors” in Part I, Item 1A. These risk factors will be important to consider in determining future results and should be reviewed in their entirety. These forward-looking statements are expressed in good faith, and Mosaic and Vivint believe there is a reasonable basis for them. However, there can be no assurance that the events, results or trends identified in these forward-looking statements will occur or be achieved. Forward-looking statements speak only as of the date they are made, and neither Mosaic nor Vivint is under any obligation, and expressly disclaim any obligation, to update, alter or otherwise revise any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law. Readers should carefully review the statements set forth in the reports, which Mosaic has filed or will file from time to time with the SEC.

In addition to factors previously disclosed in Mosaic’s S-4 and reports filed with the SEC and those identified elsewhere in this communication, the following factors, among others, could cause actual results to differ materially from forward-looking statements or historical performance: ability to meet the closing conditions to the merger; delay in closing the merger; failure to realize the benefits expected from the proposed transaction; the effects of pending and future legislation; risks related to disruption of management time from ongoing business operations due to the proposed transaction; business disruption following the transaction; risks related to Mosaic’s or Vivint’s indebtedness; other consequences associated with mergers, acquisitions and divestitures and legislative and regulatory actions and reforms; risks of the smart home and security industry, including risks of and publicity surrounding the sales, subscriber origination and retention process; the highly competitive nature of the smart home and security industry and product introductions and promotional activity by competitors; litigation, complaints, product liability claims and/or adverse publicity; cost increases or shortages in smart home and security technology products or components; the introduction of unsuccessful new smart home services; privacy and data protection laws, privacy or data breaches, or the loss of data; the impact of the Vivint Flex Pay plan to Vivint’s business, results of operations, financial condition, regulatory compliance and customer experience; and Vivint’s ability to successfully compete in retail sales channels.

Any financial projections in this communication are forward-looking statements that are based on assumptions that are inherently subject to significant uncertainties and contingencies, many of which are beyond Mosaic’s and Vivint’s control. The assumptions and estimates underlying the projected results are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the projections. The inclusion of projections in this communication should not be regarded as an indication that Mosaic and Vivint, or their representatives, considered or consider the projections to be a reliable prediction of future events. Annualized, pro forma, projected and estimated numbers are used for illustrative purpose only, are not forecasts and may not reflect actual results.

This communication is not intended to be all-inclusive or to contain all the information that a person may desire in considering an investment in Mosaic and is not intended to form the basis of an investment decision in Mosaic. All subsequent written and oral forward-looking statements concerning Mosaic and Vivint, the proposed transaction or other matters and attributable to Mosaic and Vivint or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements above.
