PROTECTION ONE ANNOUNCES SECOND QUARTER 2007 RESULTS

In First Post-Merger Quarter, Company Is on Schedule Realizing Merger Benefits

Company to conduct conference call to review results today at 10:00 a.m. Eastern Time

LAWRENCE, Kan., Aug. 14, 2007 — Protection One, Inc. (NASDAQ: PONE), one of the leading providers of security monitoring services in the United States, today reported unaudited financial results for its second quarter ended June 30, 2007. As previously reported, Protection One (the “Company”) completed its merger (“Merger”) with Integrated Alarm Services Group, Inc. (“IASG”) on April 2, 2007, thus the results described below for the second quarter of 2007 include the performance of IASG subsequent to the Merger. Results for the second quarter of 2006 reflect the performance of only Protection One and do not include the performance of IASG. All comparisons are to the quarter ended June 30, 2006 unless otherwise indicated.

Largely as a result of the Merger, the Company’s total revenue in the second quarter of 2007 increased by 38.7% to $93.1 million. Second quarter 2007 net loss was $(8.1) million, or $(0.32) per share, compared to a net loss of $(6.7) million, or $(0.36) per share in 2006, reflecting higher amortization and interest expense. Adjusted EBITDA increased to $29.5 million in the second quarter of 2007 compared to $21.4 million in the same period of 2006.

Richard Ginsburg, Protection One’s president and chief executive officer, commented, “We are pleased to report success translating the revenue increase from the Merger with IASG into adjusted EBITDA growth of 37.8% in the second quarter of 2007. Merger synergies, which yielded lower IASG operating costs, accounted for most of the improvement.

“We achieved an important milestone in our Merger integration plan when we migrated billing and customer care of IASG’s residential accounts on to Protection One systems on schedule at the end of

June. We believe we are on track to migrate commercial billing and customer care on to Protection One systems by the end of the third quarter and to assimilate accounting and financial reporting functions by the end of the year.”

Ginsburg added: “In connection with the Merger, we have realigned our businesses into three segments: Retail, Wholesale, and Multifamily. Our Retail reporting unit delivered good operating metrics while making significant progress integrating IASG’s operations. Excluding IASG’s RMR, Retail annualized net attrition (net of move in accounts) decreased to 10.0% in the second quarter of 2007 from 10.8% one year ago. Including IASG’s RMR, Retail annualized net attrition (net of move in accounts) was 11.6% in the quarter just ended. Our Retail reporting unit added $628,000 RMR in the quarter just ended, up 14.4% from additions in 2006’s second quarter. IASG’s commercial group contributed to our growth in commercial additions which represented 42.7% of total RMR additions in the second quarter, up from 41.1% one year ago.

“Our Wholesale reporting unit contributed significantly to our adjusted EBITDA growth. In the second quarter of 2007, revenues and operating costs in Criticom, the acquired IASG wholesale business, were in line with our expectations. We expect variability in results for the next several quarters until we achieve full integration of our Wholesale monitoring platform in the first half of 2008 and until the Wholesale base is growing consistently with the help of new initiatives we are putting in place.

“Our Multifamily reporting unit was unaffected by the Merger and its performance was consistent with results in prior quarters. Consequently, revenues declined in the second quarter of 2007 compared to 2006. We continue to devote resources to reducing attrition, increasing RMR additions and managing costs commensurate with revenue levels.”

Ginsburg concluded: “While it would be premature to draw too many conclusions from just one quarter of results after the Merger, we are pleased to be on schedule with respect to our integration plan and remain optimistic that we can realize the benefits we anticipated.”

Adjusted EBITDA, RMR and net debt, as described in this release, are all non-GAAP financial measures and are described in greater detail in the attached schedules. For a reconciliation of these non-GAAP measures, see the attached schedules.

Segment Results in the Second Quarter of 2007

Retail

The Company’s Retail segment sells, installs, monitors and maintains electronic security and life safety systems directly for residential and business customers. As of June 30, 2007, the Company served approximately 617,000 retail customers generating approximately $20.7 million RMR.

Total revenue in the second quarter of 2007 increased 31.9% to $73.7 million primarily due to the Retail customers acquired in the Merger. For the same reason, monitoring and related services revenue increased 27.7%. Excluding the impact of the Merger, monitoring and related services revenue would have increased by an estimated 1.8% due to lower attrition and continued growth in RMR additions.

Monitoring and service costs as a percentage of monitoring and service revenue increased to 29.2% from 27.6%, due to higher monitoring labor, telecom costs, service job labor and fuel costs. The increase in costs relates to an increasing percentage of residential customers with enhanced services, such as cellular back-up, and commercial customers.

Retail operating income improved to $2.0 million from a loss of $(0.4) million. The revenue increase from the Merger was accompanied by relatively smaller increases in selling and G&A expense, and outright commercial installations increased. Also, Retail operating income in the second quarter of 2007 reflects Merger-related severance costs of $2.4 million compared to recapitalization costs of $4.5 million in the second quarter of 2006. These differences more than offset a $5.1 million increase in amortization of intangibles and depreciation expense due to the Merger.

Gross retail attrition in the second quarter of 2007 was 13.6% compared to 13.2% in 2006, excluding the impact of Hurricane Katrina. The increase stems from a higher attrition rate on the acquired IASG retail portfolio. Excluding that retail RMR, Retail gross attrition would have been 12.1% in the quarter just ended.

Integration of IASG’s commercial RMR portfolio with Protection One’s systems is on target for completion by the end of September.

Wholesale

The Company’s Wholesale segment contracts with independent security alarm dealers nationwide to provide alarm system monitoring services to their residential and business customers. As of June 30, 2007, this unit served approximately 4,400 dealers by monitoring approximately 840,000 homes and businesses on their behalf. These relationships provided almost $3.7 million RMR. The combination of CMS, Protection One’s pre-Merger wholesale subsidiary, and Criticom will soon be known as Criticom Monitoring Services (or CMS).

The Merger lifted total revenue in the second quarter of 2007 to $11.1 million, up from $2.7 million one year ago, when revenues were comprised solely of results from Protection One’s pre-merger wholesale monitoring subsidiary. Wholesale operating income increased to $783,000 from $412,000, as growth in monitoring revenues exceeded significant Merger-related increases in general and administrative expenses and amortization of intangibles and depreciation expense.

Wholesale added $360,000 RMR during the quarter, up significantly from $52,000 added one year ago, due to Criticom’s relationships with some of the faster growing independent alarm companies. Wholesale RMR may vary more than Retail RMR depending on the decisions of the Company’s largest wholesale customers to invest in creating new accounts, to retain or sell what they create, and to maintain relationships with the Company. Wholesale RMR attrition in the quarter was 21.3%, up from 18.2% in 2006. The current period’s results are typical of wholesale attrition recorded by IASG.

Multifamily

The Company’s Multifamily reporting unit provides monitoring and maintenance services for electronic security systems to tenants of multifamily residences under long-term contracts with building owners and managers. As of June 30, 2007, Multifamily had $2.5 million of RMR arising from approximately 285,000 units in more than 2,000 rental properties in 600 cities.

Multifamily revenue continued to decline in the second quarter due to an inability to create Multifamily RMR in excess of attrition. Monitoring and related services revenue declined 5.5% while the total of monitoring costs, selling expense, and G&A remained relatively stable. As a result, Multifamily operating income declined to $1.6 million from $2.2 million.

Excluding the impact of Hurricane Katrina, Multifamily RMR attrition improved modestly to 12.2% compared to 12.4% last year, partly due to increased management focus on this aspect of the business.

Recurring Monthly Revenue

Total Company RMR as of June 30, 2007 was $26.8 million, up from $19.9 million as of June 30, 2006. Excluding the impact of the Merger, the Company estimates that RMR at June 30, 2007 would have been $20.2 million, an increase of $0.3 million or 1.5% from RMR at June 30, 2006.

See “Non-GAAP Reconciliations” in the attached schedules for a reconciliation of RMR to reported revenue.

Net Debt

The Company’s total debt and capital leases, excluding debt discounts and premiums, as of June 30, 2007 was $525.9 million, compared to $410.8 million as of December 31, 2006. The increase arises from debt assumed in connection with the Merger.

The Company had $296.2 million outstanding under its senior secured credit facility as of June 30, 2007. The senior secured credit facility is subject to an early maturity date of June 30, 2008 if the Company’s 8.125% senior subordinated notes remain outstanding at that time. Accordingly, the indebtedness outstanding under the senior secured credit facility is classified and presented as a current liability as of June 30, 2007. The Company intends to repay or refinance its indebtedness related to the 8.125% senior subordinated notes or amend the covenants contained in, or obtain a waiver from the lenders party to, the senior credit agreement before June 30, 2008.

The Company’s cash and equivalents as of June 30, 2007 were $29.1 million compared to $24.6 million at December 31, 2006.

Net debt as of June 30, 2007 was $494.7 million compared to $371.3 million at December 31, 2006.

See “Non-GAAP Reconciliations” in the attached schedules for a reconciliation of net debt to reported debt and cash and equivalents.

Shares Outstanding

The Company had 25,076,469 weighted average number of shares outstanding in the second quarter of 2007 compared to 18,239,724 in the second quarter of 2006.

On July 12, 2007, the Company filed a Registration Statement on Form S-3 with the U.S. Securities and Exchange Commission for a proposed public offering of its common stock. The Registration Statement may be viewed on the Company’s website under SEC Filings at www.ProtectionOne.com

Adjusted EBITDA is used by management in evaluating segment performance and allocating resources, and management believes it is used by many analysts following the security industry. This information should not be considered as an alternative to any measure of performance as promulgated under accounting principles generally accepted in the United States of America, such as loss before income taxes or cash flow from operations. Items excluded from Adjusted EBITDA are significant components in understanding and assessing the consolidated financial performance of the Company. The Company’s calculation of Adjusted EBITDA may be different from the calculation used by other companies and comparability may be limited. Management believes that presentation of a non-GAAP financial measure such as Adjusted EBITDA is useful because it allows investors and management to evaluate and compare the Company’s operating results from period to period in a meaningful and consistent manner in addition to standard GAAP financial measures.
