Non-GAAP Measures To provide investors with additional information in connection with our results as determined by generally accepted accounting principles in the United States (“GAAP”), we disclose the following non-GAAP financial measures: Adjusted EBITDA, Adjusted EBITDA margin, Free Cash Flow, Free Cash Flow before special items, Unlevered Free Cash Flow before special items, Historical Combined Free Cash Flow, Unlevered Historical Combined Free Cash Flow before special items, and Supplemental Pro Forma Financial Information. These measures are not financial measures calculated in accordance with GAAP, and should not be considered as a substitute for net income, operating income, or any other measure calculated in accordance with GAAP, and may not be comparable to a similarly titled measure reported by other companies. Adjusted EBITDA and Adjusted EBITDA margin We believe that the presentation of Adjusted EBITDA is appropriate to provide additional information to investors about certain non-cash items and about unusual items that we do not expect to continue at the same level in the future, as well as other items. Further, we believe Adjusted EBITDA provides a meaningful measure of operating profitability because we use it for evaluating our business performance, making budgeting decisions, and comparing our performance against that of other peer companies using similar measures. We define Adjusted EBITDA as net income or loss adjusted for (i) interest, (ii) taxes, (iii) depreciation and amortization, including depreciation of subscriber system assets and other fixed assets and amortization of dealer and other intangible assets, (iv) amortization of deferred costs and deferred revenue associated with subscriber acquisitions, (v) share-based compensation expense, (vi) purchase accounting adjustments under GAAP, (vii) merger, restructuring, integration, and other costs, (viii) financing and consent fees, (ix) foreign currency gains/losses, (x) losses on extinguishment of debt, (xi) radio conversion costs, (xii) management fees and other charges, and (xiii) other non-cash items. There are material limitations to using Adjusted EBITDA. Adjusted EBITDA does not take into account certain significant items, including depreciation and amortization, interest expense, income tax expense, and other adjustments which directly affect our net income or loss. These limitations are best addressed by considering the economic effects of the excluded items independently, and by considering Adjusted EBITDA in conjunction with net income or loss as calculated in accordance with GAAP. The Adjusted EBITDA discussion above is also applicable to its margin measure, which is calculated as Adjusted EBITDA as a percentage of monitoring and related services revenue. Free Cash Flow We define Free Cash Flow as cash from operating activities less cash outlays related to capital expenditures. We define capital expenditures to include purchases of property, plant, and equipment; subscriber system asset additions; and accounts purchased through our network of authorized dealers or third parties outside of our authorized dealer network. In arriving at Free Cash Flow, we subtract cash outlays related to capital expenditures from cash from operating activities because they represent long-term investments that are required for normal business activities. As a result, subject to the limitations described below, Free Cash Flow is useful measure of our cash available to repay debt, make other investments, and pay dividends. Free Cash Flow adjusts for cash items that are ultimately within management’s discretion to direct, and therefore, may imply that there is less or more cash that is available than the most comparable GAAP measure. Free Cash Flow is not intended to represent residual cash flow for discretionary expenditures since debt repayment requirements and other non-discretionary expenditures are not deducted. These limitations are best addressed by using Free Cash Flow in combination with the GAAP cash flow numbers. Free Cash Flow before special items We define Free Cash Flow before special items as Free Cash Flow adjusted for charges and gains related to (i) acquisitions, (ii) integrations, (iii) restructuring, (iv) impairments, and (v) other income or charges that may mask the operating results or business trends of the Company. As a result, subject to the limitations described below, Free Cash Flow before special items is useful measure of our cash available to repay debt, make other investments, and pay dividends. Free Cash Flow before special items adjusts for cash items that are ultimately within management’s discretion to direct, and therefore, may imply that there is less or more cash that is available than the most comparable GAAP measure. Free Cash Flow before special items is not intended to represent residual cash flow for discretionary expenditures since debt repayment requirements and other non-discretionary expenditures are not deducted. These limitations are best addressed by using Free Cash Flow before special items in combination with the GAAP cash flow numbers. Unlevered Free Cash Flow before special items We define Unlevered Free Cash Flow before special items as Free Cash Flow before special items adjusted for cash interest paid. As a result, subject to the limitations described below, Unlevered Free Cash Flow before special items is a useful measure of our cash available to service debt, make other investments, and pay dividends. Unlevered Free Cash Flow before special items adjusts for contractual interest payments as well as cash items that are ultimately within management’s discretion to direct, and therefore, may imply that there is less or more cash that is available than the most comparable GAAP measure. Unlevered Free Cash Flow before special items is not intended to represent residual cash flow for discretionary expenditures since debt service requirements and other non-discretionary expenditures are not deducted. These limitations are best addressed by using Unlevered Free Cash Flow before special items in combination with the GAAP cash flow numbers. Historical Combined Free Cash Flow and Unlevered Historical Combined Free Cash Flow before special items We have presented Free Cash Flow and Unlevered Free Cash Flow before special items on a Historical Combined basis for the 2015 and 2016 periods presented in this appendix, which represents the mathematical additions of Free Cash Flow and Unlevered Free Cash Flow before special items of the Company, The ADT Corporation, Protection One, and ASG. Historical Combined Free Cash Flow and Unlevered Historical Combined Free Cash Flow before special items adjust cash items that are ultimately within management’s discretion to direct, and therefore, may imply that there is less or more cash that is available than the most comparable GAAP measure. Historical Combined Free Cash Flow and Unlevered Historical Combined Free Cash Flow before special items are not intended to represent residual cash flow for discretionary expenditures since debt service requirements and other non-discretionary expenditures are not deducted. These limitations are best addressed by using Historical Combined Free Cash Flow and Unlevered Historical Combined Free Cash Flow before special items in combination with the GAAP cash flow numbers. Supplemental Pro Forma Financial Information We have presented supplemental pro forma financial information for the 2015 and 2016 periods presented in this appendix, which includes pro forma adjustments necessary to reflect the ADT Acquisition and the Formation Transactions as if they had occurred on January 1, 2015. We believe that Supplemental Pro Forma financial information is appropriate to illustrate the effect that the ADT Acquisition and the Formation Transactions had on our financial performance, assuming that such transactions took place on January 1, 2015. Financial Outlook The Company is not providing a quantitative reconciliation of our financial outlook for Adjusted EBITDA and Free Cash Flow before special items to net income (loss) and net cash provided by operating activities, which are their corresponding GAAP measures because these GAAP measures that we exclude from our non-GAAP financial outlook are difficult to reliably predict or estimate without unreasonable effort due to their dependence on future uncertainties, such as special items discussed above under the heading — Non-GAAP Measures “Adjusted EBITDA” and “Free Cash Flow before special items.” Additionally, information that is currently not available to the Company could have a potentially unpredictable and potentially significant impact on its future GAAP financial results.
