Three and Nine Months Ended September 30, 2013 Results

Ascent Capital Group, Inc.

For the three months ended September 30, 2013, Ascent reported net revenue of $115.8 million, an increase of 36.8% compared to $84.7 million for the three months ended September 30, 2012. For the nine months ended September 30, 2013 net revenue increased 27.4% to $318.3 million. The increase in net revenue for the three and nine month time periods is primarily attributable to the growth in the number of Monitronics’ subscriber accounts and the increase in average RMR per subscriber.

Ascent’s total cost of services for the three and nine months ended September 30, 2013 increased 56.5% and 44.2% to $20.2 million and $51.0 million, respectively. The increase for the three and nine months ended September 30, 2013 is primarily due to an increased number of accounts monitored across the cellular network and in those having interactive and home automation services, which result in higher operating and service costs. Also contributing to the increase was the inclusion of Security Networks monitoring costs of $2.7 million for both the three and nine months ended September 30, 2013.

Selling, general & administrative (“SG&A”) costs for the three months ended September 30, 2013 increased 30.8% to $23.9 million, and increased 20.4% to $65.1 million for the first nine months of 2013. The increase is primarily attributable to increases in Monitronics SG&A costs as well as the inclusion of Security Networks SG&A costs of $2.1 million. The increase in Monitronics SG&A costs are attributable to increased payroll expenses of approximately $581,000 and $2.2 million for the three and nine months ended September 30, 2013, and acquisition and integration costs related to professional services and other costs incurred in connection with the Security Networks acquisition.  Acquisition costs recognized in the three and nine months ended September 30, 2013 were $1.0 million and $2.5 million. Integration costs recognized in both the three and nine months ended were $535,000. Additionally, Ascent’s consolidated stock-based compensation expense increased approximately $387,000 and $1.6 million for the three and nine months ended September 30, 2013, related to restricted stock and stock option awards granted to certain executives and directors of Ascent in 2012.

For the three months ended September 30, 2013, Ascent’s Adjusted EBITDA increased 35.2% to $75.7 million. During the first nine months of 2013, Ascent’s Adjusted EBITDA increased 29.4% to $218.2 million. The increases in Adjusted EBITDA for both periods was primarily due to revenue and subscriber growth at Monitronics, partially offset by higher operating and service costs.

Ascent reported a net loss from continuing operations for the three and nine months ended September 30, 2013 of $12.5 million and $10.0 million, compared to a net loss from continuing operations of $13.7 million and $24.4 million for the three and nine months ended September 30, 2012.

Monitronics International, Inc.

For the three months ended September 30, 2013, Monitronics reported net revenue of $115.8 million, an increase of 36.8% compared to $84.7 million for the three months ended September 30, 2012. For the nine months ended September 30, 2013 net revenue increased 27.4% to $318.3 million. The increase in net revenue for the three and nine months ended September 30, 2013 is attributable to the growth in the number of subscriber accounts and the increase in average RMR per subscriber.  The growth in subscriber accounts reflects the effects of the acquisition of Security Networks, which included over 200,000 subscriber accounts, purchases of over 120,000 accounts through Monitronics’ authorized dealer program subsequent to September 30, 2012, and the purchase of approximately 111,000 accounts in various bulk buys over the last 12 months.  In addition, average RMR per subscriber increased from $38.28 as of September 30, 2012 to $40.70 as of September 30, 2013.  Partially offsetting the increase in net revenue for the three and nine months ended September 30, 2013 is the negative impact of a $2.5 million fair value adjustment that reduced deferred revenue acquired in the Security Networks acquisition.

Monitronics’ total cost of services for the three and nine months ended September 30, 2013 increased 56.5% and 44.2% to $20.2 million and $51.0 million. The increase for the three and nine months ended September 30, 2013 is primarily due to an increased number of accounts monitored across the cellular network and in those having interactive and home automation services, which result in higher operating and service costs. Also contributing to the increase was the inclusion of $2.7 million in Security Networks monitoring costs.

Monitronics’ SG&A costs for the three months ended September 30, 2013 increased 35.3% to $20.0 million and 23.4% to $54.0 million for the first nine months of 2013. The increased Monitronics SG&A costs are attributable to increased payroll expenses of approximately $581,000 and $2.2 million for the three and nine months ended September 30, 2013, and acquisition and integration costs related to professional services and other costs incurred in connection with the Security Networks acquisition. Acquisition costs recognized in the three and nine months ended September 30, 2013 were $1.0 million and $2.5 million. Integration costs recognized in the three and nine months ended are $535,000.

Monitronics’ Adjusted EBITDA for the three months ended September 30, 2013 was $77.6 million, an increase of 35.2% versus the three months ended September 30, 2012. For the nine months ended September 30, 2013, Monitronics’ Adjusted EBITDA increased 27.1% to $217.5 million. The increase in Adjusted EBITDA for the quarter is primarily due to revenue and subscriber growth at Monitronics driven by the acquisition of Security Networks, purchases through Monitronics’ authorized dealer program and acquisitions of various bulk buys over the last twelve months. Monitronics’ Adjusted EBITDA as a percentage of revenue was 67.0% in the quarter ended September 30, 2013, compared to 67.8% for the three months ended September 30, 2012.

Adjusted EBITDA

We evaluate the performance of our operations based on financial measures such as revenue and “Adjusted EBITDA.”  Adjusted EBITDA is defined as net income (loss) before interest expense, interest income, income taxes, depreciation, amortization (including the amortization of subscriber accounts and dealer network), realized and unrealized gain/(loss) on derivative instruments, restructuring charges, stock-based and other non-cash long-term incentive compensation, and other non-cash or nonrecurring charges.   Ascent Capital believes that Adjusted EBITDA is an important indicator of the operational strength and performance of its business, including the business’ ability to fund its ongoing acquisition of subscriber accounts, its capital expenditures and to service its debt.  In addition, this measure is used by management to evaluate operating results and perform analytical comparisons and identify strategies to improve performance.   Adjusted EBITDA is also a measure that is customarily used by financial analysts to evaluate the financial performance of companies in the security alarm monitoring industry and is one of the financial measures, subject to certain adjustments, by which Monitronics’ covenants are calculated under the agreements governing their debt obligations.  Adjusted EBITDA does not represent cash flow from operations as defined by generally accepted accounting principles (“GAAP”), should not be construed as an alternative to net income or loss and is indicative neither of our results of operations nor of cash flows available to fund all of our cash needs.  It is, however, a measurement that Ascent Capital believes is useful to investors in analyzing its operating performance.  Accordingly, Adjusted EBITDA should be considered in addition to, but not as a substitute for, net income, cash flow provided by operating activities and other measures of financial performance prepared in accordance with GAAP.  Adjusted EBITDA is a non-GAAP financial measure.  As companies often define non-GAAP financial measures differently, Adjusted EBITDA as calculated by Ascent Capital should not be compared to any similarly titled measures reported by other companies.
