Alarm.com Reports 2015 Second Quarter Results

— SaaS and license revenue increased to $34.1 million, a 27% increase year-over-year —

— Total revenue in the second quarter increased to $51.9 million, a 23% increase year-over-year —

VIENNA, Va., August 6, 2015 — Alarm.com Holdings, Inc. (Nasdaq: ALRM), the leading platform solution for the connected home, today reported financial results for the second quarter ended June 30, 2015. The company also introduced its financial outlook for the 2015 third quarter and full year.

“We maintained solid revenue growth and profitability in our first reporting period as a public company,” said Steve Trundle, President and CEO of Alarm.com. “At the same time, we continued to invest in our core technology to enhance our connected home platform and to expand our footprint in international markets, and we anticipate continuing to step up our investments in the coming quarters while also continuing to produce positive cash flow from operations.”

Mr. Trundle continued, “The smart home, and the Internet of Things more broadly, has emerged as one of the most promising categories in consumer technology. We believe consumers prefer to acquire smart home technologies through the security channel because of the professional installation, support and home monitoring services they deliver. In partnership with thousands of trusted service providers who offer Alarm.com to their customers, we are at the forefront of empowering consumers with the security, efficiency, awareness and convenience of the connected home.”

Second Quarter 2015 Highlights

Balance Sheet and Cash Flow

Recent Business Highlights

Jennifer Moyer, Chief Financial Officer, commented, “The completion of our recent IPO provides us with additional capital and greater brand visibility as we execute on our growth strategy moving forward. Customers want a comprehensive connected home platform and they want great service. We believe our go-to-market strategy in partnership with our service providers is delivering upon this market need as highlighted by our 93% SaaS and license revenue renewal rate for the period. We expect that Alarm.com and its dealers will continue to benefit from strong consumer demand and growth of our core businesses, as our technology increasingly becomes a “must have” for anyone considering a security or home automation system.”

Financial Outlook

Alarm.com is introducing its outlook for the third quarter of 2015 and full year. Alarm.com will provide its outlook for hardware and other revenue as well as total company profitability on an annual basis only as the timing of revenue for this category is less predictable than SaaS and license revenue timing. Additionally, the company intends to continue its strategy of prioritizing growth in SaaS revenue and our customer base over sales of hardware in general.

Non-GAAP Financial Measures

To supplement our unaudited 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 net income, non- GAAP adjusted net income attributable to common stockholders, non-GAAP adjusted net income per share, and non-GAAP weighted average fully diluted common shares outstanding. We have included non-GAAP measures in this press release because they are key measures used by our management to understand and evaluate our core operating performance and trends and generate future operating plans, make strategic decisions regarding the allocation of capital, and investments in initiatives that are focused on cultivating new markets for our solutions. We believe that these non-GAAP measures of our financial results provide useful information to investors and others in understanding and evaluating Alarm.com’s 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.

With respect to our expectations under “Financial Outlook” above, reconciliation of Adjusted EBITDA and Adjusted Net Income 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, the measures and effects of stock-based compensation expense specific to equity compensation awards that are directly impacted by unpredictable fluctuations in our stock price. We expect the variability of the above charges to have a significant, and potentially unpredictable, impact on our future GAAP financial results.

Alarm.com excludes one or more of the following items from non-GAAP financial measures:

Dividends paid to participating securities and income allocated to participating securities. Dividends paid to participating securities relate to $19.0 million of the $20.0 million June 2015 cash dividends paid in June 2015 to our preferred stockholders at the rate of (1) $0.36368 per share of Series A preferred stock and (2) $0.72736 per share of Series B preferred stock and Series B-1 preferred stock. We are excluding these dividends and income allocated to participating securities to improve the comparability of our results from period to period. Immediately prior to the completion of our offering on July 1, 2015, all of our outstanding shares of preferred stock converted into an aggregate of 35,017,884 shares of our common stock and, in future periods, all of our net income will be available to common stockholders.

Stock-based compensation: We exclude stock-based compensation expense, which relates to 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. Included in the three and six months ended June 30, 2015 stock-based compensation expense is $0.8 million related to the repurchase of an employee’s stock awards. 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 from our non-GAAP financial measures improves the comparability of our results to the results of other companies in our industry.

Litigation expense: We exclude litigation expense because we do not consider legal costs incurred in intellectual property litigation to be indicative of our core operating performance.

Amortization: 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 for our non-GAAP financial measures because we do not consider amortization when we evaluate our on-going 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 Alarm.com’s performance to other companies in our industry as other companies may be more or less acquisitive than Alarm.com and therefore amortization expense may vary significantly by company based on their acquisition history.

Interest expense: We exclude interest expense because we do not consider it part of our ongoing results of operations.

Other (expense) / income, net: We exclude other (expense) / income, net because we do not consider it part of our ongoing results of operations.
