A definitive proxy statement/consent solicitation statement/prospectus will also be 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, when they become available, 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.

Annual Report on Form10-K for the year ended December 31, 2018 and its Quarterly Report on Form10-Q for the quarterly periods ended March 31, 2019, and June 30, 2019, which are filed with the SEC.

This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 including, but not limited to, Mosaic’s and Vivint’s expectations or predictions of future financial or business performance or 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 Form10-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 reports filed with the SEC and those identified elsewhere in this presentation, 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, including approval by stockholders of Mosaic and Vivint on the expected terms and schedule and the risk that regulatory approvals required for the merger are not obtained or are obtained subject to conditions that are not anticipated; 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 Smart Home’s ability to successfully compete in retail sales channels. Any financial projections in this presentation 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. While all projections are necessarily speculative, Mosaic and Vivint believe that the preparation of prospective financial information involves increasingly higher levels of uncertainty the further out the projection extends from the date of preparation. 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 presentation 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 presentation is not intended to beall-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.

Definition ofnon-GAAP financial measures This presentation includes Adjusted EBITDA, Covenant Adjusted EBITDA, and Unlevered Free Cash Flow, which are supplemental measures that are not required by, or presented in accordance with, accounting principles generally accepted in the United States (“GAAP”). “Adjusted EBITDA” is defined as net income (loss) before interest, taxes, depreciation, amortization,non-cash compensation, MDR fees, and certain othernon-recurring expenses or gains. Management believes that the presentation of Adjusted EBITDA is appropriate to provide additional information to investors because it is frequently used by securities analysts, investors, and other interested parties in their evaluation of the operating performance of companies in industries similar to Vivint’s. “Covenant Adjusted EBITDA” is defined as net income (loss) before interest expense (net of interest income), income and franchise taxes and depreciation and amortization (including amortization of capitalized subscriber acquisition costs), further adjusted to exclude the effects of certain contract sales to third parties,non-capitalized subscriber acquisition costs, stock based compensation and certain unusual,non-cash, nonrecurring and other items permitted in certain covenant calculations under the agreements governing Vivint’s notes, the credit agreement governing the term loan and the credit agreement governing the revolving credit facility. Management believes that the presentation of Covenant Adjusted EBITDA is appropriate to provide additional information to investors about the calculation of, and compliance with, certain financial covenants contained in the agreements governing Vivint’s notes, the credit agreements governing the revolving credit facility and the term loan. “Free Cash Flow” is defined as cash flow from operations less capital expenditures. Management believes that the presentation of Unlevered Free Cash Flow is appropriate to provide additional information to investors because it is frequently used by securities analysts, investors, and other interested parties in their evaluation of the operating performance of companies in industries similar to Vivint’s. “Unlevered Free Cash Flow” is defined as cash flow from operations less capital expenditures plus net interest expense adjusted for tax at the effective rate of 0%. Management believes that the presentation of Unlevered Free Cash Flow is appropriate to provide additional information to investors because it is frequently used by securities analysts, investors, and other interested parties in their evaluation of the operating performance of companies in industries similar to Vivint’s. Management cautions investors that amounts presented in accordance with Vivint’s definition of Adjusted EBITDA, Covenant Adjusted EBITDA, Free Cash Flow, and Unlevered Free Cash Flow may not be comparable to similar measures disclosed by other issuers, because not all issuers and analysts calculate Adjusted EBITDA, Covenant Adjusted EBITDA, and Unlevered Free Cash Flow in the same manner. Adjusted EBITDA, Free Cash Flow, Covenant Adjusted EBITDA, and Unlevered Free Cash Flow are not measurements of Vivint’s financial performance under GAAP and should not be considered as alternatives to net income (loss) or any other performance measures derived in accordance with GAAP or as alternatives to cash flows from operating activities as a measure of Vivint’s liquidity. See foregoing Appendix A slides for reconciliations of this presentation for reconciliations of Adjusted EBITDA, Covenant Adjusted EBITDA, Free Cash Flow, and Unlevered Free Cash Flow to net loss for Vivint, which management believes is the most closely comparable financial measure calculated in accordance with GAAP. Adjusted EBITDA, Covenant Adjusted EBITDA, Free Cash Flow, and Unlevered Free Cash Flow should be considered in addition to and not as a substitute for, or superior to, financial measures presented in accordance with GAAP. 56

Certain definitions Total Subscribers - is the aggregate number of active Smart Home and security subscribers at the end of a given period. Total Monthly Service Revenue – is the contracted recurring monthly service billings to our smart home and security subscribers, based on the Total Subscribers number as of the end of a given period. Average Monthly Subscription Revenue per User – or AMSRU, is Total MSR divided by Total Subscribers at the end of a given period. Attrition Rate - is the aggregate number of canceled Smart Home and security subscribers during the prior 12 month period divided by the monthly weighted average number of Total Subscribers based on the Total Subscribers at the beginning and end of each month of a given period. Subscribers are considered canceled when they terminate in accordance with the terms of their contract, are terminated by Vivint or if payment from such subscribers is deemed uncollectible (when at least four monthly billings become past due). If a sale of a service contract to third parties occurs, or a subscriber relocates but continues their service, Vivint does not consider this as a cancellation. If a subscriber transfers their service contract to a new subscriber, Vivint does not consider this a cancellation. Average Subscriber Lifetime - in number of months, is 100% divided by Vivint’s expected long-term annualized attrition rate multiplied by 12 months. Net Service Costs - is the average monthly service costs incurred during the period (both period and capitalized service costs), including monitoring, customer service, field service and other service support costs, less totalnon-recurring Smart Home services billings for the period. Net Service Cost per Subscriber - is the average monthly service costs incurred during the period (both period and capitalized service costs), including monitoring, customer service, field service and other service support costs, less totalnon-recurring Smart Home services billings for the period divided by average monthly Total Subscribers for the same period. Net Service Margin - is the monthly average service RPU for the period, less total average net service costs for the period divided by the monthly average MSR for the period. New Subscribers - is the aggregate number of net new Smart Home and security subscribers originated during a given period. This metric excludes new subscribers acquired by the transfer of a service contract from one subscriber to another. Net Subscriber Acquisition Costs - is the net cash cost to create new Smart Home and security subscribers during a given 12 month period. These costs include commissions, Products, installation, marketing, sales support and other allocations (general and administrative and overhead) less upfront payment received from the sale of Products associated with the initial installation, and installation fees. These costs exclude capitalized contract costs and upfront proceeds associated with contract modifications. Net Subscriber Acquisition Costs per New Subscriber - is the net cash cost to create new Smart Home and security subscribers during a given 12 month period divided by New Subscribers for that period. These costs include commissions, Products, installation, marketing, sales support and other allocations (general and administrative and overhead) less upfront payment received from the sale of Products associated with the initial installation, and installation fees. These costs exclude capitalized contract costs and upfront proceeds associated with contract modifications. Total Bookings - is total monthly service revenue for New Subscribers multiplied by Average Subscriber Lifetime, plus total Product revenue to be recognized over the contract term from New Subscribers. Total Monthly Service Revenue for New Subscribers - is the contracted recurring monthly service billings to Vivint’s New Subscribers during a given period. Average Monthly Service Revenue per New Subscriber - is the Total Monthly Service Revenue for New Subscribers divided by New Subscribers during a given period. Lifetime Service Revenue per New Subscriber - is the Total Monthly Service Revenue for New Subscribers divided by New Subscribers, multiplied by Average Subscriber Lifetime. Lifetime Service Margin per New Subscriber (LTV margin) - is Total Monthly Service Revenue/Total service RPU for New Subscribers less Net Service Cost per Subscriber multiplied by Average Subscriber Lifetime LTV / Net SAC - is the Lifetime Service Margin per New Subscriber plus RIC equipment revenue per new subscriber, divided by Net Subscriber Acquisition Costs per New Subscriber including financing costs Monthly revenue per user (RPU) - is the recurring monthly amount billed to a smart home and security subscriber for products and services. RPU excludes cash received from equipment sales associated with the initial installation. Monthly service revenue (Service RPU) - is the recurring monthly amount billed to a smart home and security subscriber for services. Service RPU excludes cash received from product sales associated with the initial installation.
