Item 2.02. Results of Operations and Financial Condition.

On November 2, 2016, APX Group Holdings, Inc. (the “Company”) issued a press release announcing the results of the Company’s operations for the quarter ended September 30, 2016. The full text of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference in this Item 2.02.

In connection with the press release, the Company held a telephone conference call that was webcast on November 2, 2016. Presentation slides referenced during the conference call were available on the Company’s website for viewing by call participants. A transcript of that call together with presentation slides referenced during the conference call are furnished as Exhibit 99.2 to this Current Report on Form 8-K and are incorporated by reference in this Item 2.02.

The attached transcript and presentation slides contain information that includes Adjusted EBITDA, a non-GAAP financial measure as defined in Regulation G adopted by the Securities and Exchange Commission.

The Company defines Adjusted EBITDA 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 governing the Company’s notes and the credit agreement governing the Company’s revolving credit facility.

The Company believes 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 the Company’s notes and the credit agreement governing the Company’s revolving credit facility.

The Company cautions investors that amounts presented in accordance with the Company’s 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 the Company’s 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 the Company’s liquidity. Tables providing reconciliations of Adjusted EBITDA to the closest GAAP financial measure are included with the press release and the presentation slides filed as Exhibits 99.1 and 99.2, respectively, to this Current Report on Form 8-K.

The information in this Current Report on Form 8-K and Exhibits 99.1 and 99.2 is being furnished pursuant to Item 2.02 of Form 8-K and shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934 (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing made by the Company under the Securities Act of 1933 or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

In addition, the press release, transcript and presentation slides furnished as exhibits to this report include forward-looking statements as defined by the Private Securities Litigation Reform Act of 1995 regarding, among other things, the Company’s plans, strategies and prospects, both business and financial. These statements are based on the beliefs and assumptions of management. Although the Company believes that its plans, intentions and expectations reflected in or suggested by these forward-looking statements are reasonable, the Company cannot assure you that it will achieve or realize these plans, intentions or expectations. Forward-looking statements are inherently subject to risks, uncertainties and assumptions. Generally, statements that are not historical facts, including statements concerning the Company’s 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.

Forward-looking statements are not guarantees of performance. You should not put undue reliance on these statements which speak only as of the date hereof. You should understand that the following important factors, in addition to those discussed in “Risk Factors” in the Company’s annual report on form 10-K for the year ended December 31, 2015, filed with the Securities Exchange Commission (SEC), as such factors may be updated from time to time in the Company’s periodic filings with the SEC, which are available on the SEC’s website at www.sec.gov, could affect the Company’s future results and could cause those results or other outcomes to differ materially from those expressed or implied in the Company’s forward-looking statements:

In addition, the origination and retention of new subscribers will depend on various factors, including, but not limited to, market availability, subscriber interest, the availability of suitable components, the negotiation of acceptable contract terms with subscribers, local permitting, licensing and regulatory compliance, and the Company’s ability to manage anticipated expansion and to hire, train and retain personnel, the financial viability of subscribers and general economic conditions.

These and other factors that could cause actual results to differ from those implied by the forward-looking statements in the press release, transcript and presentation slides furnished as exhibits to this report are more fully described in the “Risk Factors” section of the Company’s annual report filed on Form 10-K for the year ended December 31, 2015 as such factors may be updated from time to time in the Company’s periodic filings with the SEC. The risks described in “Risk Factors” are not exhaustive. New risk factors emerge from time to time and it is not possible for the Company to predict all such risk factors, nor can the Company assess the impact of all such risk factors on the Company’s business or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in any forward-looking statements. All forward-looking statements attributable to the Company or persons acting on its behalf are expressly qualified in their entirety by the foregoing cautionary statements. The Company undertakes no obligations to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise.
