APX GROUP HOLDINGS, INC. REPORTS FIRST QUARTER 2017 RESULTS

1^st Quarter 2017 Highlights

Provo, UT – May 10, 2017 – APX Group Holdings, Inc. (“APX Group,” “Vivint Smart Home,” “Vivint,” or the “Company”) today reported financial and operational results for the fiscal quarter ended March 31, 2017.

Todd Pedersen, CEO of APX Group, commented, “We’re pleased with our progress during the first quarter from both a financial and operational perspective. We reported 17.8% year-over-year total revenues growth, and at the same time increased our Adjusted EBITDA, while continuing to invest in our technology and smart home capabilities. As planned, we began the roll-out of Vivint Flex Pay in partnership with Citizens Bank during the first quarter and we announced on May 4, 2017, a retail national partnership with Best Buy (NYSE: BBY) to offer our smart home products and services in Best Buy stores.” Mr. Pedersen continued, “While we have a lot of work ahead of us, we’re looking forward to a successful 2017.”

Revenue and Subscriber Data

APX Group reported total revenues of $205.4 million for the three month period ended March 31, 2017, an increase of 17.8%, as compared to the same period in 2016. The increase in total revenues of $31.1 million was primarily driven through an increase in recurring and other revenue of $29.5 million. Recurring and other revenue increased $21.4 million year-over-year through an increase of approximately 133,000 Total Subscribers, while higher ARPU drove $7.1 million of the recurring and other revenue increase versus the same period in 2016.

The Company added 39,292 net new smart home subscribers during the first quarter of 2017. The Company’s inside sales channel increased originations by 9.1% to 24,498 net new smart home subscribers in the three months ended March 31, 2017, as compared to the same period in 2016. Average Revenue per New User for the three months ended March 31, 2017 increased by $5.98, from $62.01 to $67.99, compared to the same period in 2016.

Summary of Financial and Portfolio Metrics for the Last Five Quarters

($ in millions, except for subscriber data)

APX Group CFO Mark Davies commented, “We had a two-fold focus during the first quarter of 2017: First, drive improvements in our operating metrics, which we did with strong revenue growth, in particular through our inside sales channel, a reduction in our subscriber acquisition cost multiple, a significant year-over-year increase in Average Revenue per New User and an improvement in customer attrition. Second, execute on our IT and infrastructure improvements related to an SAP enterprise resource planning system implementation, and the process changes and system buildouts to facilitate the launch of Vivint Flex Pay, both of which had successful initial rollouts.” Mr. Davies added, “We also successfully completed a $300 million aggregate principal amount bond offering, which was met with strong investor reception. In summary, we believe we’re off to a good start to the year.”

Costs and Expenses

Operating expenses for the first quarter of 2017 increased by 23.1%, from $58.0 million in the first quarter of 2016 to $71.4 million. The $13.4 million increase in operating expenses was primarily due to an increase of $7.4 million in personnel and related costs, $3.3 million of equipment costs and $2.1 million for contracted services and information technology costs to support the growth in the Total Subscribers. The $3.3 million of equipment costs includes approximately $1.8 million of equipment cost related to the upgrading of customers’ cellular radios from 2G to 3G and certain other updates to their systems to support the change in technology.

Selling expenses, net of capitalized subscriber acquisition costs, for the first quarter of 2017, were $34.8 million compared to $28.9 million for the same period in 2016. The 20.4% year-over-year increase in selling expenses primarily attributable to $4.0 of personnel and related costs, $0.8 million of lead generation costs associated with growth in the inside sales new subscriber originations and $0.7 million in information technology costs related to rolling out new iPads and credit card reader devices for the direct-to-home sales representatives to use with the Vivint Flex Pay program.

General and administrative (“G&A”) expenses, net of allocations, for the first quarter of 2017 were $38.9 million compared to $30.4 million for the first quarter of 2016. The year-over-year increase of $8.5 million was primarily due to an increase of $3.6 million in personnel and related costs, $1.2 million for marketing expenses, $0.7 million of information technology costs and $0.7 million of bad debt expenses.

Adjusted EBITDA and Net Loss

Adjusted EBITDA for the first quarter of 2017 grew by 12.3% to $115.4 million on a net loss of $82.6 million, compared to Adjusted EBITDA of $102.8 million on a net loss of $45.1 million for the first quarter of 2016.

Recent Developments

Vivint Flex Pay Plan

On January 3, 2017, we announced the introduction of the Vivint Flex Pay program which is expected to be our primary sales and pricing model going forward. Under the Vivint Flex Pay plan, we launched two new financing programs: (1) a consumer financing program with Citizens Bank, N.A., in the first quarter of 2017, offering qualified customers in the United States an opportunity to finance the purchase of products and related installation used in connection with Vivint’s smart home and security services and (2) a retail installment contract program (“RICs”) funded by Vivint, with respect to the purchase of products and related installation to certain customers who do not qualify to participate in the Citizens Bank, N.A. consumer financing program, but qualify under our historical underwriting criteria. We may also establish credit programs either directly or through an affiliate or pursuant to an agreement with a third party to provide installment loans or similar products to customers that do not qualify to participate in the consumer financing program. Alternatively, customers may purchase the products and related installation at the outset of the service contract with cash or credit card.

With the Vivint Flex Pay plan, customers pay separately for the products and related installation and our service offerings. Under the consumer financing program, qualified customers are eligible for installment loans provided by a third party financing provider of up to $4,000 for either 42 or 60 months. In connection with the consumer financing program, a subsidiary of ours entered into an agreement with Citizens Bank, N.A. pursuant to which Citizens will be the exclusive provider of installment loans under the consumer financing program for our customers who are eligible for such loans. Pursuant to the agreement with Citizens, we pay a monthly fee to Citizens based on the average daily outstanding balance of the loans provided by Citizens and we share with Citizens liability for credit losses, with Vivint being responsible for approximately 5% to 100% of lost principal balances, depending on factors specified in the agreement. The initial term of the agreement is five years, subject to automatic, one-year renewals unless terminated by either party in accordance with its terms. We are initially offering RICs for 42 or 60 month terms to certain customers who do not qualify to participate in the consumer financing program, but qualify under our historical underwriting criteria, and may establish credit programs either directly or through an affiliate or pursuant to an agreement with a third party to provide installment loans or similar products to such customers.

Additional 2022 Notes

On February 1, 2017, APX issued and sold an additional $300.0 million aggregate principal amount of 7.875% senior secured notes due in 2022 at a price of 108.250%. A portion of the proceeds from the offering of these notes was used to redeem $300.0 million aggregate principal amount of the Company’s existing 6.375% senior secured notes due in 2019 and pay the related redemption premium, as well as to pay all fees and expenses related thereto and any remaining proceeds will be used for general corporate purposes.

Strategic Retail Partnership with Best Buy

On May 4, 2017, we announced that we have entered into a strategic partnership agreement with Best Buy Stores, L.P., in which the parties will jointly market and sell smart home products and services. Under the terms of the agreement, Best Buy will offer certain Vivint smart home products and services in approximately 400 Best Buy retail stores on or before the first anniversary date of the agreement, with a continuing rollout to a significant number of additional Best Buy stores by the second anniversary date of the Agreement expected. We expect that Best Buy will begin offering Vivint’s products in services in these stores in the second or third quarter of 2017. The agreement also contains certain exclusivity conditions to which the parties are subject. We expect to devote significant management attention as well as significant capital and other resources to our partnership with Best Buy over the course of the agreement. Historically, we have primarily originated subscribers through our direct-to-home and inside sales channels. There is no assurance that our retail partnership with Best Buy or other third-party distribution arrangements will become a significant source of subscriber originations or revenue for us. There is also no assurance that Best Buy will continue to distribute our products and services after the expiration or termination of the Best Buy agreement. If the Best Buy agreement expires or is terminated, or if Best Buy otherwise ceases to distribute our products and services, we may not be able to establish alternative retail distribution channels for our products and services.

Liquidity

As of March 31, 2017, the Company’s liquidity position on a consolidated basis, defined as cash on hand, short-term marketable securities and available borrowing capacity under the Company’s revolving credit facility, was approximately $319 million.

Certain Credit Statistics

Our net leverage ratio, defined as the ratio of net debt to LTM Adjusted EBITDA, was 5.4x at March 31, 2017.

Certain Definitions

Total Subscribers – The aggregate number of active smart home and security subscribers at the end of a given period

Monthly Revenue per User (“RPU”) – The recurring monthly revenue billed to a smart home and security subscriber

Total Revenue per User – The aggregate RPU billed for all smart home and security subscribers

Average RPU (“ARPU”) – The Total RPU divided by Total Subscribers

Average Revenue per New User (“ARPNU”) – The aggregate RPU for new subscribers originated during a period divided by the number of new subscribers originated during such period

Attrition – The aggregate number of canceled smart home and security subscribers during a period divided by the monthly weighted average number of total smart home and security subscribers for such period. Subscribers are considered canceled when they terminate in accordance with the terms of their contract, are terminated by us, or if payment from such subscribers is deemed uncollectible (when at least four monthly billings become past due). Sales of contracts to third parties, and certain moves and takeovers are excluded from the attrition calculation

Net Subscriber Acquisition Costs – Defined as direct and indirect costs to create a new smart home and security subscriber. These include commissions, equipment, installation, marketing and other allocations (G&A and overhead), less activation fees, installation fees and up sell revenue. These costs also exclude residuals and long-term equity expenses associated with the direct-to-home sales channel.

Net Subscriber Acquisition Multiple – Defined as Net Subscriber Acquisition Costs, divided by the number of net new subscribers originated, and then divided by the ARPNU

Adjusted EBITDA – 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, non-recurring and other items permitted in certain covenant calculations under the indentures governing our notes and the credit agreement governing our revolving credit facility.

Last Quarter Annualized Adjusted EBITDA (“LQA Adjusted EBITDA”) – A common industry measure used to reflect the step-function in earnings during the sales season related to the subscribers generated from April to August. LQA Adjusted EBITDA, calculated by multiplying Adjusted EBITDA for the most recent fiscal quarter by 4, represents the ongoing earnings power of Vivint’s current subscriber base and is potentially a more relevant metric than LTM due to the recurring nature of the revenue and expected earnings.

Net Service Cost – Defined as total service costs, including monitoring, customer service, field service and other allocations (G&A and overhead) costs, less total service revenue divided by total service subscribers

Net Service Margin – Defined as ARPU per subscriber less Net Service Costs divided by ARPU

Statement Regarding Non-GAAP Financial Measures

Non-GAAP Financial Measures

This earnings release includes Adjusted EBITDA, which is a supplemental measure that is 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 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, non-recurring and other items permitted in certain covenant calculations under the indentures governing our notes and the credit agreement governing our revolving credit facility.

We believe that the presentation of Adjusted EBITDA is appropriate to provide additional information to investors about the calculation of, and compliance with, certain financial covenants in the indentures governing our notes and the credit agreement governing our revolving credit facility. We caution investors that amounts presented in accordance with our definition of Adjusted EBITDA may not be comparable to similar measures disclosed by other issuers, because not all issuers and analysts calculate Adjusted EBITDA in the same manner.

Adjusted EBITDA is not a measurement of our financial performance under GAAP and should not be considered as an alternative to net income (loss) or any other performance measures derived in accordance with GAAP or as an alternative to cash flows from operating activities as a measure of our liquidity.

Adjusted EBITDA margin represents the ratio of Adjusted EBITDA to total revenues.

See the following table for a quantitative reconciliation of Adjusted EBITDA to Net Loss, which we believe is the most comparable financial measure calculated in accordance with GAAP.
