APX GROUP HOLDINGS, INC. REPORTS 4^th QUARTER and FULL YEAR 2017 RESULTS

4^th Quarter 2017 Highlights

Full Year 2017 Highlights

Provo, UT – March 6, 2018 – APX Group Holdings, Inc. (“APX Group”, “Vivint” or the “Company”) today reported financial and operational results for the fourth quarter and full year ended December 31, 2017.

“At the beginning of 2017, we established an operational plan to implement a number of significant initiatives across the Vivint platform,”said Todd Pedersen, Chief Executive Office of APX Group. Flex Pay and our partnership with Citizens bank would require a shift in our customer value proposition and a reengineering of our sales and marketing processes, but would fundamentally improve the cash flow dynamics of our business. In terms of sales channel expansion, we determined to establish a market presence in an assisted-sale retail format, by agreeing to a national roll-out of a co-branded offering with Best Buy (NYSE: BBY). Finally, we set-out to invest in key infrastructure related to product quality, customer experience and enterprise efficiency. “While we realized these initiatives would be challenging the longer-term benefits will strengthen our balance sheet, better retain our customers and provide a more competitive business model. At the end of the year, I would say that we’ve effectively achieved these objectives and gained valuable learnings that will be incorporated in our go-forward strategies and plans.”

Revenue and Subscriber Data

APX Group reported total revenues of $235.8 million for the three month period ended December 31, 2017, an increase of $31.3 million, or 15.3%, as compared to the same period in 2016. The increase in total revenues was primarily driven by $23.3 million in recurring and other revenues from an increase in Total Subscribers of 12.7% and the recognition of deferred product revenue and retail installment contract (“RIC”) imputed interest of $13.5 million. The increase in total revenues was partially offset by $8.0 million from a decrease in the Average Monthly Service Revenue per User of $1.86 attributable to the Company’s transition to Vivint Flex Pay.

The Company added 52,342 New Subscribers during the fourth quarter of 2017, a 31.5% increase compared to 39,805 New Subscribers during the same period in 2016. The large format retail sales channel contributed 11,627 New Subscribers during the quarter.

APX Group reported total revenues of $882.0 million for the full year period ended December 31, 2017, an increase of 16.4% or $124.1 million, as compared to 2016. The primary drivers of the increase were $87.0 million in recurring and other revenue driven by an increase in Total Subscribers and $28.7 million of deferred product revenue and RIC imputed interest associated with the Company’s transition to Vivint Flex Pay in early 2017.

In 2017, the Company originated 279,735 New Subscribers, with approximately 48% of the New Subscribers coming from the inside sales channel and the Company’s expansion into the large format retail sales channel and 52% from the direct-to-home channel.

Summary of Quarterly Key Financial and Portfolio Metrics

($ in millions, except for subscriber data)    

“Looking back at 2017, I would call out several observations and assessments,” said Mark Davies, Chief Financial Officer of APX Group. “Arguably, and most importantly, our Vivint Flex Pay program generated $211 million of cash flow at point of sale, reducing our Net Subscriber Acquisiton Costs from $1,996 in 2016 to $1,545 in 2017. We implemented the consumer

financing component of the Flex Pay program with Citizens Bank early in the second quarter, so we would expect cash flows from Vivint Flex Pay to improve in 2018, from a full-year impact of the program. The implementation of Vivint Flex Pay had a negative impact on sales velocity, as our sales channels digested the change in the customer offerings, worked through process changes and developed updated training programs. Our inside sales channel was relatively efficient in this transition, growing New Subscribers 15% year over year, while our direct-to-home channel added 30,000 fewer New Subscribers during the year. Over time, we believe sales productivity will return to pre-Flex Pay levels. Despite these transitionary challenges, we grew 2017 revenue by 16.4%.”

Mr. Davies continued, “Similar to prior investment cycles, we chose to increase our information technology and engineering resources in 2017. More specifically, in our Innovation organization, we invested in hardware, software and connectivity quality-related programs, which we believe will yield a better customer experience and eventually lower attrition and service costs. Our information technology investments centered on our proprietary Genie platform which integrates sales, field service and customer support; Vivint Flex Pay functionality; channel expansion; and several other infrastructure programs, including an SAP ERP platform. From a service cost perspective, we saw a year-over-year increase of $0.97 per month in Net Service Costs per Subscriber, while still maintaining robust, healthy service margins of 72.1%. There are two primary elements to the increase in Net Service Costs per Subscriber; First, as we increase the number of smart devices in a customer’s home, we see an increase in the cost to service; Second, we chose to optimize customer experience by investing in Field Service responsiveness and tech support coverage. Best Buy was another investment during the year. Start up and productivity costs related to sales and installation were the primary driver for higher than normal subscriber acquisition and support costs. We expect to improve productivity and reduce costs in this channel over the next year.”

Costs and Expenses

Operating expenses in the fourth quarter of 2017 increased by $22.6 million to $91.7 million as compared to $69.1 million in the fourth quarter of 2016. The Company’s expansion of new sales channels, primarily the large format retail sales channel, accounted for $10.7 million of the $22.6 million year-over-year increase. Total operating expenses in the fourth quarter, excluding the $10.7 million, increased $11.9 million, or 17.2%. The primary drivers for the $11.9 million increase were $8.2 million of personnel and related support costs and $3.0 million in equipment and shipping costs to support the 145, 952 increase in Total Subscribers.

Full year 2017 operating expenses increased 21.4% from $264.9 million in 2016 to $321.5 million in 2017, including $16.2 million of operating expenses directly associated with the Company’s efforts to expand its sales channels.    Excluding the $16.2 million, operating expenses increased by 15.3% or $40.4 million, in line with full year revenue growth of 16.4%. The $40.4 million increase in operating expenses is primarily attributed to $28.0 million in personnel and related costs for field service and customer care, $8.7 million in equipment and shipping costs, $3.4 million for information technology related services and a $1.6 million increase in payment processing and bank fees associated with the increase in Total Subscribers and the Company’s introduction of Vivint Flex Pay, which requires a customer to use a credit or debit card as their payment method. The increase in operating expenses was partially offset by $1.6 million in savings from facilities and other support costs.

Net service cost per user was $15.69, which contributed to a net service margin of 72.1% for the full year 2017, as compared to $14.72 in 2016. The increase in net service cost per user is due to investments in service levels and overall customer experience, along with an increase in the number of smart home devices per customer.

Fourth quarter of 2017 selling expenses, net of capitalized subscriber acquisition costs, were $63.5 million, compared to $32.6 million for the same period in 2016. The 94.8% year-over-year increase in selling expenses is primarily attributable to $25.2 million to support the Company’s sales channel expansion, mostly related to the large format retail sales channel. Selling expenses in the fourth quarter of 2017 associated with the direct-to-home and inside sales channels increased by $5.7 million. The primary drivers of the $5.7 million increase relate to an increase of $3.1 million in facilities and IT costs and $1.8 million in personnel and related costs.

Selling expenses for the full year 2017, net of capitalized subscriber acquisition costs, were $198.3 million versus $131.4 in 2016. Selling expenses associated with the Company’s sales channel expansion, primarily the large format retail sales channel, accounted for $47.2 million of the year-over-year increase. The selling expenses in the direct to home and inside sales channels increased by $19.7 million, including a $6.2 million increase in personnel and related costs, a $5.7 million increase in housing and facilities costs and $3.8 million increase in IT related cost, partially offset by a savings of $1.0 for employee licensing.

The Company’s Net Subscriber Acquisition Costs per New Subscriber was $1,594 in 2017 as compared to $1,996 for the same period in 2016. The Company’s introduction of Vivint Flex Pay in early 2017 increased the average proceeds collected at point of sale by approximately $732 per new subscriber.    

General and administrative (“G&A”) expenses, net of allocations, for the fourth quarter of 2017 were $61.2 million as compared to $40.6 million for the same period in 2016. The year-over-year increase of $20.6 million was primarily due to a litigation settlement of $10.0 million, $5.7 million in personnel and related costs, along with $3.1 million to support expansion of the Company’s large format retail sales channel.

Full year 2017 G&A expenses, net of allocations, increased 30.739% to $188.4 million as compared to $144.2 million in 2016. The $10.0 million litigation settlement in the fourth quarter contributed 7.1% of the year-over-year increase. The remaining $35.2 million increase was primarily due to $15.8 million in personnel and related costs and $10.9 million in costs to support the Company’s expansion of the large format retail sales channel. Other costs associated with the year over year increase include $3.7 million for financial and legal services.

Adjusted EBITDA and Net Loss

Adjusted EBITDA for the fourth quarter of 2017 was $125.9 million and net loss was $135.4 million, as compared to adjusted EBITDA of $118.3 million and net loss was $71.2 million for the same period in 2016.

Adjusted EBITDA for the full year ended December 31, 2017, was $490.3 million and net loss was $410.2 million, as compared to $444.1 million and net loss of $276.0 million for the same period in 2016.

Certain Definitions

Total Subscribers – the aggregate number of active smart home and security subscribers at the end of a given period. This metric excludes subscribers originated under pilot programs.

Total Monthly Service Revenue (MSR) – the aggregate, contracted recurring monthly Service billings to our smart home and security subscribers, based on the number of Total Subscribers as of the end of a given period. This metric reflects billings on our Services and excludes monthly billings for the purchases of our Products.

Average Monthly Service Revenue per User (AMSRU) – MSR divided by the number of Total Subscribers as of the end of a given period.

Total Monthly Revenue (Total MR) – the aggregate, 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, plus deferred product and interest revenue recognized during the last month of the period.

Average Monthly Revenue per User (AMRU) – Total MR divided by Total Subscribers at the end of a given period.

Attrition Rate – 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 us 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, we do not consider this as a cancellation. If a subscriber transfers their service contract to a new subscriber, we do not consider this as a cancellation.

Net Service Cost per User – average monthly service costs for the period, including monitoring, customer service, field service and other service support costs, less total non-recurring product and service billings for the period divided by average monthly Total Subscribers for the same period.

Net Service Margin – is the sum of the months-end MSR for the period, less total net service costs for the period divided by the sum of the months-end MSR for the period.

New Subscribers – 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 and subscribers originated under pilot programs.

Net Subscriber Acquisition Costs per New Subscriber – the direct and indirect costs to create a new smart home and security subscriber divided by New Subscribers for a given 12 month period. These costs include commissions, equipment, installation, marketing, sales support and other allocations (general and administrative and overhead); less cash received from product sales associated with the initial installation, activation fees, installation fees and upsell revenue.

Statement Regarding 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, the historical results of Solar and certain unusual, non-cash, non-recurring and other items permitted in certain covenant calculations under the indentures and other agreements 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 covenants in the indentures and other agreements 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.

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.
