Non-GAAP Financial Measures

To supplement our consolidated selected financial data presented on a basis consistent with GAAP, this press release contains certain non-GAAP financial measures, including adjusted EBITDA, non-GAAP adjusted income before income taxes, non-GAAP adjusted net income, non-GAAP adjusted income attributable to common stockholders before income taxes, non-GAAP adjusted net income attributable to common stockholders, non-GAAP adjusted net income attributable to common stockholders per share and non-GAAP free cash flow. We have included non-GAAP measures in this press release because they are financial, operating or liquidity measures used by our management to (i) understand and evaluate our core operating performance and trends and generate future operating plans, (ii) make strategic decisions regarding the allocation of capital and investments in initiatives that are focused on cultivating new markets for our solutions and (iii) provide useful information to management about the amount of cash generated by the business after necessary capital expenditures. We also use adjusted EBITDA as a performance measure under our executive bonus plan. Further, we believe that these non-GAAP measures of our financial results provide useful information to investors and others in understanding and evaluating our results of operations, business trends and financial condition. While we believe the use of these non-GAAP measures provides useful information to investors and management in analyzing our financial performance, non-GAAP measures have inherent limitations in that they do not reflect all of the amounts and transactions that are included in our financial statements prepared in accordance with GAAP. Non-GAAP measures do not serve as an alternative to GAAP nor do we consider our non-GAAP measures in isolation, accordingly we present non-GAAP financial measures only in connection with GAAP results. We urge investors to consider non-GAAP measures only in conjunction with our GAAP financials and to review the reconciliation of our non-GAAP financial measures to the comparable GAAP financial measures, which are included in this press release.

We consider non-GAAP free cash flow to be a liquidity measure, which we define as cash flows from operating activities less purchases of property and equipment.

With respect to our expectations under "Financial Outlook" above, reconciliation of adjusted EBITDA and adjusted net income attributable to common stockholders guidance to the closest corresponding GAAP measure is not available without unreasonable efforts on a forward-looking basis due to the high variability, complexity and low visibility with respect to the charges excluded from these non-GAAP measures, in particular, non-ordinary course litigation expense, acquisition-related expense and tax windfall adjustments can have unpredictable fluctuations based on unforeseen activity that is out of our control and/or cannot reasonably be predicted. We expect the above charges to have a significant and potentially highly variable impact on our future GAAP financial results.

We exclude one or more of the following items from non-GAAP financial and operating measures:

Stock-based compensation expense: We exclude stock-based compensation expense, which relates to stock options and other forms of equity incentives primarily awarded to employees of Alarm.com, because they are non-cash charges that we do not consider when assessing the operating performance of our business. Additionally, the determination of stock-based compensation expense can be calculated using various methodologies and is dependent upon subjective assumptions and other factors that vary on a company-by-company basis. Therefore, we believe that excluding stock-based compensation expense from our non-GAAP financial measures improves the comparability of our results to the results of other companies in our industry.

Secondary offering expense: We exclude secondary offering expense because we do not consider costs associated with the secondary offering to be indicative of our core operating performance and we believe that the exclusion of this expense allows us to better provide meaningful information about our operating performance, facilitates comparisons to our historical operating results and improves the comparability of our results to the results of other companies in our industry.

Litigation expense: We exclude non-ordinary course litigation expense because we do not consider legal costs and settlement fees incurred in litigation and litigation-related matters of non-ordinary course lawsuits and other disputes, particularly costs incurred in ongoing intellectual property litigation, to be indicative of our core operating performance. We do not adjust for ordinary course legal expenses, including those expenses resulting from maintaining and enforcing our intellectual property portfolio and license agreements.

Acquisition-related (benefit) / expense: Included in operating expenses are incremental costs directly related to business and asset acquisitions as well as changes in the fair value of contingent consideration liabilities, when applicable. We exclude acquisition-related expense from our non-GAAP financial measures because we believe that the exclusion of this expense allows us to better provide meaningful information about our operating performance, facilitates comparisons to our historical operating results, improves the comparability of our results to the results of other companies in our industry, and ultimately, we believe helps investors better understand the acquisition-related expense and the effects of the transaction on our results of operations.

Depreciation expense: We record depreciation primarily for investments in property and equipment. We exclude depreciation in calculating adjusted EBITDA because we do not consider depreciation when we evaluate our ongoing business operations. For non-GAAP adjusted net income, non-GAAP adjusted net income attributable to common stockholders and non-GAAP adjusted net income attributable to common stockholders per share, basic and diluted, we do not exclude depreciation.

Amortization expense: GAAP requires that operating expenses include the amortization of acquired intangible assets, which principally include acquired customer relationships, developed technology and trade names. We exclude amortization of intangibles from our non-GAAP financial measures because we do not consider amortization expense when we evaluate our ongoing business operations, nor do we factor amortization expense into our evaluation of potential acquisitions, or our measurement of the performance of those acquisitions. We believe that the exclusion of amortization expense enables the comparison of our performance to other companies in our industry as other companies may be more or less acquisitive than us and therefore, amortization expense may vary significantly by company based on their acquisition history. Although we exclude amortization of acquired intangible assets from our non-GAAP financial measures, management believes that it is important for investors to understand that such intangible assets were recorded as part of purchase accounting and contribute to revenue generation.

Amortization of debt discount and debt issuance costs: We record amortization of debt discount and debt issuance costs related to our convertible senior notes as interest expense. We exclude amortization of debt discount and debt issuance costs from our non-GAAP adjusted net income, non-GAAP adjusted net income attributable to common stockholders and non-GAAP adjusted net income attributable to common stockholders per share, basic and diluted, because we believe that the exclusion of this non-cash interest expense will provide for more meaningful information about our financial performance.

Interest expense: We record interest expense primarily related to our debt facility. We exclude interest expense in calculating our adjusted EBITDA calculation. For non-GAAP adjusted net income, non-GAAP adjusted net income attributable to common stockholders and non-GAAP adjusted net income attributable to common stockholders per share, basic and diluted, we do not exclude interest expense other than the interest expense related to the amortization of debt discount and debt issuance costs related to our convertible senior notes as discussed above.

Interest income and other income / (expense), net: We exclude interest income and other income / (expense), net from our non-GAAP financial measures because we do not consider it part of our ongoing results of operations.

Income taxes: We exclude the impact related to our benefit from income taxes from our adjusted EBITDA calculation. We do not consider this tax adjustment to be part of our ongoing results of operations.
