ASCENT CAPITAL GROUP ANNOUNCES FINANCIAL RESULTS FOR THE THREE MONTHS ENDED MARCH 31, 2014

Englewood, CO — May 8, 2014 — Ascent Capital Group, Inc. (“Ascent or the “Company”) (Nasdaq: ASCMA) has reported results for the three months ended March 31, 2014. 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 1 million residential and commercial customers. 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 months ended March 31, 2014 increased 32.7%

· Ascent’s Adjusted EBITDA(2) for the three months ended March 31, 2014 increased 23.3%

· Monitronics’ Adjusted EBITDA(3) for three months ended March 31, 2014 increased 28.6%

· Monitronics subscriber accounts as of March 31, 2014 increased 27.9% to 1,046,785

· Average RMR per subscriber(4) as of March 31, 2014 increased 3.5% to $41.15

· Management completed the transitioning of Security Networks’ operations from Florida to Texas in April 2014

Ascent Chairman and Chief Executive Officer, Bill Fitzgerald stated, “We are pleased with Monitronics’ solid financial performance and the successful completion of the Security Networks integration, which was finalized in April.”

“At the holding company level, our balance sheet remains strong and we continue to pursue productive and accretive investments in the alarm monitoring industry and adjacent sectors, while being opportunistic about share repurchases.”

Mike Haislip, President and Chief Executive Officer of Monitronics said, “During the first quarter Monitronics revenue increased 32% while Adjusted EBITDA grew a solid 28%, despite severe winter weather that periodically affected our dealers across the country. Total subscriber accounts were up 28% over the first quarter of last year and our attrition level increased modestly from 12.2% to 12.3%, and was unchanged from year-end.

“The first quarter also included the ongoing Security Networks’ integration and, due to the strong efforts of our operating team, on April 24th we successfully completed the transition of all Security Networks accounts to be serviced and monitored out of our call center in Dallas. We originally projected that operational efficiencies from the combined business would drive $4-6 million in annual cost savings, and we are on track to exceed those estimates. We are excited about where our business stands and its future prospects.”

Three Months Ended March 31, 2014 Results

Ascent Capital Group, Inc.

For the three months ended March 31, 2014, Ascent reported net revenue of $132.9 million, an increase of 32.7% compared to $100.2 million for the three months ended March 31, 2013. This increase in net revenue is primarily attributable to increases in Monitronics’ subscriber accounts and average RMR per subscriber, which were both driven in part by the August 16, 2013 acquisition of Security Networks.

Ascent’s total cost of services for the three months ended March 31, 2014 increased 45.3% to $22.1 million. This increase is primarily attributable to Monitronics’ subscriber growth over the last twelve months, as well as increases in cellular and service costs, as described in more detail below.

Selling, general & administrative (“SG&A”) costs for the three months ended March 31, 2014 increased 34.5% to $26.5 million. The increase is primarily attributable to increases in Monitronics SG&A expenses as well as the inclusion of Security Networks SG&A of $3.9 million for the three months ended March 31, 2014. The increase in Monitronics SG&A is partly attributable to redundant staffing and operating costs at our Dallas, Texas headquarters and integration costs incurred in advance of transitioning Security Networks’ operations from Florida to Texas.

For the quarter, Ascent’s Adjusted EBITDA increased 23.3% to $87.9 million. This increase is primarily due to revenue and subscriber growth at Monitronics.

Ascent reported a net loss from continuing operations for the three months ended March 31, 2014 of $9.4 million, compared to net income of $2.3 million for the same period in 2013.

Monitronics International, Inc.

For the three months ended March 31, 2014, Monitronics reported net revenue of $132.9 million, an increase of 32.7% compared to $100.2 million for the three months ended March 31, 2013. The increase in net revenue is attributable to a 27.9% increase in the number of subscriber accounts and a 3.5% increase in the average RMR per subscriber to $41.15 as of March 31, 2014. The growth in subscribers reflects the Security Networks acquisition in August 2013, which included over 200,000 subscriber accounts, as well as the acquisition of over 135,000 accounts through Monitronics’ authorized dealer program subsequent to March 31, 2013, and the purchase of approximately 18,200 accounts in bulk buys over the last 12 months.

Monitronics’ total cost of services for the three months ended March 31, 2014 increased 45.3% to $22.1 million. The increase for the three months ended March 31, 2014 is primarily attributable to subscriber growth over the last twelve months, as well as increases in cellular and service costs. Cellular costs increased due to more accounts being monitored across the cellular network, which often include home automation services. This has also resulted in higher service costs as existing subscribers upgrade their systems.

Monitronics’ SG&A costs for the three months ended March 31, 2014 increased 44.5% to $23.0 million compared to the prior year period. The increase is primarily attributable to subscriber growth over the last twelve months. Increased SG&A costs are also attributable to redundant staffing and operating costs at Monitronics’ Dallas, Texas headquarters and integration costs incurred in advance of transitioning Security Networks’ operations from Florida to Texas. Integration costs for the three months ended March, 31, 2014, were $1.1 million, which primarily relate to professional services rendered.

Monitronics’ Adjusted EBITDA for the three months ended March 31, 2014 was $89.3 million, an increase of 28.6% over the three months ended March 31, 2013. The increase is primarily due to revenue and subscriber growth at Monitronics driven by accounts acquired through Monitronics’ authorized dealer program, the acquisition of Security Networks and bulk account purchases over the last twelve months. Monitronics’ Adjusted EBITDA as a percentage of revenue was 67.2% in the first quarter of 2014, compared to 69.3% for the three months ended March 31, 2013.

Monitronics’ reported a net loss for the three months ended March 31, 2014 of $7.9 million compared to net income of $1.3 million in the prior year period.

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.
