MONITRONICS INTERNATIONAL, INC. ANNOUNCES RESULTS

FOR THIRD QUARTER OF FISCAL 2005

Dallas, Texas [June 20, 2005] -- Monitronics International, Inc., a leading national provider of security alarm monitoring services, today released its financial results for the three months and nine months ended March 31, 2005.

Third Quarter Results

Total revenues increased $3.6 million, or 10% to $41.5 million in the three months ended March 31, 2005 from $37.9 million in the three months ended March 31, 2004.

Earnings before interest, taxes, depreciation and amortization ("EBITDA") for the three months ended March 31, 2005 was $28.8 million, an increase of 5.5% from $27.3 million for the three months ended March 31, 2004.

The Company reported a net loss of $1.3 million for the three months ended March 31, 2005 compared to a net income of $0.1 million for the same period last year.

Nine Months Results

Total revenues increased $12.2 million, or 11% to $123.4 million in the nine months ended March 31, 2005 from $111.2 million in the nine months ended March 31, 2004.

Earnings before interest, taxes, depreciation and amortization ("EBITDA") for the nine months ended March 31, 2005 was $86.2 million, an increase of 8% from $79.8 million for the nine months ended March 31, 2004.

The Company reported a net loss of $2.7 million for the nine months ended March 31, 2005 compared to a net loss of $4.8 million for the same period last year. The larger loss was primarily due to last year's results including $8.8 million in expenses incurred in connection with our August 2003 refinancing.

Operations Perspective

Mr. James R. Hull, Chief Executive Officer of Monitronics, commented, "In the last two quarter reports we explained a slight increase in the 12-month attrition rate as a reaction to a change in the renewal policy and that we expected that change to be temporary as we canceled a specific, small number of accounts ahead of schedule. It now appears we were correct as the trailing 3-month annualized attrition rate has gone down from 15.4% for the three months ended December 31, 2004 to an annualized attrition rate of 12.5% for the three months ended May 31, 2005. We believe this policy change will continue to reduce our attrition rate in the long term."

EBITDA represents a non-GAAP (Generally Accepted Accounting Principles) financial measure. EBITDA is a key performance measure used in the security alarm monitoring industry and is one of the financial measures, subject to adjustments, by which our covenants are calculated under the agreements governing our debt obligations. EBITDA does not represent cash flow from operations as defined by GAAP, should not be construed as an alternative to net income, and is indicative neither of our operating performance nor of cash flows available to fund all of our cash needs. A table reconciling this measure to the appropriate GAAP measure is included in this press release.

Monitronics will hold a conference call on Monday, June 20, 2005 at 3:30 p.m. CDT (Central Daylight Time) to discuss the Company's third quarter fiscal 2005 financial performance. James R. Hull, President and Chief Executive Officer, and Michael R. Meyers, Vice President and Chief Financial Officer, will host the call. The call will be open to the public.
