THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2012

Englewood, CO — November 8, 2012 - Ascent Capital Group, Inc. (“Ascent” or the “Company”) (Nasdaq: ASCMA) has reported results for the three and nine months ended September 30, 2012. Ascent is a holding company that owns Monitronics International, Inc. (“Monitronics”), one of the nation’s largest and fastest-growing home security alarm monitoring companies.

Headquartered in Dallas, Texas, Monitronics provides security alarm monitoring services to more than 717,000 residential and commercial customers as of September 30, 2012.  Monitronics’ long-term monitoring contracts provide high margin recurring revenue that results in predictable and stable cash flow.

Highlights(1):

·                  Ascent’s net revenue for the three and nine months ended September 30, 2012 increased 6.5%  and 8.2%, respectively, driven by increases in Monitronics’ subscriber accounts and average recurring monthly revenue (“RMR”) per subscriber

·                  Ascent’s balance sheet remains strong with $229.4 million of cash and marketable securities at the holding company level as of September 30, 2012

·                  Monitronics’ Adjusted EBITDA(2) for the three and nine months ended September 30, 2012 increased 3.1% and 6.1%, respectively, driven by growth in subscriber accounts and average RMR

·                  Monitronics subscriber accounts as of September 30, 2012 increased 2.9% to 717,488

·                  Monitronics average RMR per subscriber increased 2.8% to $38.28

·                  Monitronics’ acquired 93,000 subscriber accounts from Pinnacle Security on October 25th for approximately $131 million; purchased accounts represent $4.4 million of RMR

·                  Increases Monitronics total subscriber base by 13 percent to 810,000 accounts as of September 30, 2012 on a Pro Forma basis

Ascent Chairman and Chief Executive Officer, Bill Fitzgerald stated, “Our results for the third quarter once again illustrate the strength of the Monitronics business model. We are also pleased to have recently completed a significant bulk purchase of accounts, which will provide strong incremental cash flow for the business.

“At the holding company level, we continue to actively explore additional accretive acquisition opportunities within the alarm monitoring and related security industry.”

Monitronics

Mike Haislip, President and Chief Executive Officer of Monitronics said, “We are pleased to deliver another strong performance this quarter. We posted solid growth in revenue and Adjusted EBITDA and purchased over 31,000 high quality accounts in the third quarter. Our interactive and home automation services continue to gain ground amongst our subscribers with over 40% percent of new customers signing on for advanced services during the quarter.  While there are incremental telecom and field service costs associated with advanced services, these accounts provide for a higher value customer and drive increased levels of RMR.  As expected, attrition levels increased modestly given the age of accounts

in our portfolio and the increase in disconnects due to relocations which we believe are driven by improvements in the housing market.

Mr. Haislip continued, “The transaction to acquire 93,000 subscriber accounts from Pinnacle Security in late October will be highly accretive to Monitronics.  The acquired accounts are an attractive fit with solid FICO scores and strong penetration of interactive services. Following the close of the transaction, we also successfully completed the refinancing of an incremental $145 million Senior Secured Term Loan to fund the acquisition and replenish our existing revolver. The completion of this refinancing not only provides us with additional financial flexibility but also highlights the confidence the financial markets have in our business model.”

Three and Nine Months Ended September 30, 2012 Results

Ascent Capital Group, Inc.

For the three months ended September 30, 2012, Ascent reported net revenue of $84.7 million, an increase of 6.5% compared to $79.5 million for the three months ended September 30, 2011. For the nine months ended September 30, 2012 net revenue increased 8.2% to $249.9 million. The increase in net revenue for the three and nine month time periods is primarily attributable to increases in Monitronics’ subscriber accounts and average RMR per subscriber.

Ascent’s total cost of services for the three and nine months ended September 30, 2012 increased 20.5% and 20.1% to $12.9 million and $35.3 million, respectively. The increase for the three and nine months ended September 30, 2012 is primarily attributable to the significant growth in the number of interactive accounts Monitronics monitors across the cellular network versus traditional landline services, resulting in higher telecommunications and field service costs.

Selling, general & administrative (“SG&A”) costs for the three months ended September 30, 2012 increased 4.0% to $18.3 million. The increase in SG&A is primarily attributable to increased payroll, contract service, and stock-based compensation expenses at Monitronics of $832,000.  For the nine months ended September 30, 2012, SG&A decreased 3.4% to $54.1 million. The decrease is primarily attributable to a decline in administrative and corporate expenses at Ascent. The decline in SG&A was partially offset by increased payroll, marketing, and stock-based compensation expenses at Monitronics of $2.1 million.

For the three months ended September 30, 2012, Ascent’s Adjusted EBITDA increased 3.0% to $56.0 million. During the first nine months of 2012, Ascent’s Adjusted EBITDA increased 10.7% to $168.6 million. The increase in Adjusted EBITDA for the three and nine months ended September 30, 2012 was primarily due to revenue growth at Monitronics and decreased selling, general and administrative costs at the Ascent corporate level offset in part by higher telecommunications and service costs at Monitronics.

Ascent reported a net loss from continuing operations for the three and nine months ended September 30, 2012 of $13.7 million and $24.4 million, respectively, compared to a net loss from continuing operations of $5.1 million and $17.1 million for the three months and nine months ended September 30, 2011, respectively.

Monitronics International

For the three and nine months ended September 30, 2012, Monitronics reported net revenue of $84.7 million and $249.9 million, increases of 6.5% and 8.2%, respectively. The increase in net revenue for the three and nine months ended September 30, 2012 is primarily attributable to a 2.9% increase in Monitronics’ subscriber accounts and a 2.8% increase in average RMR per subscriber to $38.28 as of September 30, 2012 as compared to September 30, 2011.  The increase in net revenue for the nine months ended September 30, 2012 is also attributable in part to the negative impact on September 30, 2011 net revenue related to a $2.3 million fair value adjustment that reduced deferred revenue acquired in the Monitronics acquisition.

Monitronics’ total cost of services for the three months ended September 30, 2012 increased 20.5% to $12.9 million as compared to the prior year period. For the nine months ended September 30, 2012 Monitronics’ cost of services totaled $35.3 million, a 20.1% increase as compared to the nine months ended September 30, 2011.  The increase for the three

2

and nine months ended September 30, 2012 is primarily attributable to the significant growth in the number of interactive accounts Monitronics’ monitors across the cellular network versus traditional landline services, resulting in higher telecommunications and field service costs.

Monitronics’ SG&A costs for the three and nine months ended September 30, 2012 increased 11.2% and 8.2% to $14.8 million and $43.8 million, respectively, as compared to the respective prior year periods. The increase in SG&A for the three months ended September 30, 2012 is primarily attributable to certain Monitronics’ payroll, contract service, and stock-based compensation expenses of $832,000.  The increase in SG&A for the nine months ended September 30, 2012 is primarily attributable to certain Monitronics’ payroll, marketing, and stock-based compensation expenses of $2.1 million.  The increase in stock-based compensation expense is related to restricted stock and stock option awards granted to certain executives and employees of Monitronics in 2011 and 2012, which partially vested during 2012.

Monitronics’ Adjusted EBITDA for the three months ended September 30, 2012 was $57.4 million, an increase of 3.1% versus the three months ended September 30, 2011. For the nine months ended September 30, 2012, Monitronics’ Adjusted EBITDA increased 6.1%, to $171.1 million when compared to the nine months ended September 30, 2011. The increase in Adjusted EBITDA for the three and nine months ended September 30, 2012 is primarily due to revenue growth.

Monitronics’ Adjusted EBITDA as a percentage of revenue was 67.8% for the third quarter of 2012, compared to 70.1% for the three months ended September 30, 2011. Monitronics’ Adjusted EBITDA as a percentage of revenue for the nine months ended September 30, 2012 totaled 68.5%, compared to 69.8% for the year-ago period. The moderate decline for the three and nine months ended September 30, 2012 is primarily attributable to the increased number of accounts with interactive services monitored across the cellular network, resulting in higher telecommunications and service costs at Monitronics.

Monitronics reported a net loss for the three and nine months ended September 30, 2012 of $5.1 million and $12.6 million, respectively, compared to a net loss of $2.6 million and $4.2 million in the three and nine months ended September 30, 2011, respectively.

The table below presents subscriber data for the twelve months ended September 30, 2012 and 2011:

For the three months ended September 30, 2012, Monitronics purchased 31,187 subscriber accounts, compared to 33,205 subscriber accounts in the three months ended September 30, 2011. During the nine months ended September 30, 2012 and 2011, Monitronics purchased 81,719 and 89,828 subscriber accounts, respectively. The quarterly and nine month decline in account purchases is due to the completion of bulk purchases in the three and nine months ended September 30, 2011 versus no major bulk purchases in the quarter and nine months ended September 30, 2012. Despite this moderate decline, purchases from Monitronics’ core account generation business, or the accounts that Monitronics buys from authorized dealers each month, remained strong this quarter, up 23% over the same quarter in 2011.

Monitronics’ trailing twelve month attrition for the period ended September 30, 2012 increased to 12.0% compared to 10.9% for the twelve months ended September 30, 2011.  As expected, attrition levels increased modestly given the age of accounts in our portfolio and the increase in disconnections due to household relocations.

Pinnacle Transaction

On October 25th, Monitronics acquired approximately 93,000 subscriber accounts representing $4.4 million of total RMR from Pinnacle Security, for a purchase price of $131 million (after giving effect to certain purchase price adjustments). The accounts are an attractive fit within Monitronics customer profile with an average credit score in line with Monitronics’ overall portfolio and approximately 75% penetration of interactive services. The portfolio of accounts consists of a mix of three and five year contracts. The purchased accounts are also geographically diverse with accounts located in 40 states and Canada.

The acquisition was funded by an add-on of $145 million to the existing Credit Facility term loan, which matures March 23, 2018 and bears annual interest at LIBOR plus 4.25%, subject to a LIBOR floor of 1.25%.  The proceeds from the incremental term loan in excess of the purchase price were used to decrease outstanding principal under the Credit Facility revolver.

Ascent Liquidity and Capital Resources

At September 30, 2012, on a consolidated basis, Ascent had $106.3 million of cash and cash equivalents, $7.0 million of total restricted cash, and $142.7 million of marketable securities.  To improve its investment rate of return, the Company invests in marketable securities, consisting primarily of diversified corporate bond funds. The Company may use a portion of these assets to fund strategic acquisitions or investments or support stock repurchases.

During the nine months ended September 30, 2012, Monitronics used cash of $128.4 million to purchase subscriber accounts net of holdback and guarantee obligations and $3.6 million to fund capital expenditures.

At September 30, 2012, consolidated long-term debt included a principal balance of $987.2 million under Monitronics’ 9.125% senior notes due 2020 and senior secured credit facility due 2018.  The Senior Notes have an outstanding principal balance of $410.0 million as of September 30, 2012 and mature on April 1, 2020.  The Credit Facility term loan had an outstanding principal balance of $547.2 million as of September 30, 2012 and requires principal payments of $1.4 million per quarter with the remaining outstanding balance becoming due on March 23, 2018. The Credit Facility Revolver had an outstanding balance of $30.0 million as of September 30, 2012 and becomes due on March 23, 2017.

Adjusted EBITDA

We define “Adjusted EBITDA” as net income 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.   We believe that Adjusted EBITDA is an important indicator of the operational strength and performance of our businesses, including our businesses’ ability to fund their ongoing acquisition of subscriber accounts, their capital expenditures and to service their 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, 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 we believe is useful to investors in analyzing our 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 us should not be compared to any similarly titled measures reported by other companies.
