PROTECTION ONE ANNOUNCES SECOND QUARTER 2009 FINANCIAL RESULTS

Consistent Revenue Reported

Increases in Operating Income and Adjusted EBITDA Achieved

Conference call scheduled for 10 a.m. Eastern time today to review results

LAWRENCE, Kan., Aug. 7, 2009 — Protection One, Inc. (Nasdaq:PONE), one of the largest electronic security companies in the United States, today reported financial results for the second quarter ended June 30, 2009. All comparisons below are to the second quarter ended June 30, 2008 unless otherwise indicated.

Richard Ginsburg, Protection One’s president and chief executive officer, said, “I am pleased to report that we delivered consistent revenue and improved profitability in the second quarter. In summary, more profitable monitoring and service delivery and less investment creating new customers fueled a 10.6% increase in adjusted EBITDA over the second quarter of last year, which, along with reduced working capital requirements, allowed us to reduce net debt by $16.6 million during the quarter. With nearly 90% of our revenue generated from recurring monitoring and related services, we have very predictable cash flow, which we believe will enable us to continue to reduce net debt. Partly as a result of our emphasis on disciplined investing in these challenging economic times, new installations and creation of related recurring revenue were lower than in last year’s second quarter. We continued, though, to push ahead with building our commercial sales platform and now have more than 200 professionals pursuing commercial business. Given our emphasis in this area and signs that economic conditions are stabilizing, we are optimistic commercial sales in the second half of the year will improve.

In future quarters, we also believe we will see increasing residential lead flow from our marketing initiatives. Lastly, our Wholesale and Multifamily business units also executed well on their respective strategies and delivered solid results with good cash flow this quarter.”

Adjusted EBITDA, Recurring Monthly Revenue (“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. Please also see the attached schedules for a reconciliation of these non-GAAP measures as well as a definition of net attrition.

Second Quarter Results

Consolidated revenue in the second quarter of 2009 decreased less than one half of one percent to $92.1 million. This decrease reflects an increase in Wholesale monitoring revenue that was offset by a decline in Retail and Multifamily monitoring and service revenue.

Operating income increased to $8.9 million from $2.8 million in the second quarter of 2008 primarily due to lower amortization and depreciation expense and a reduction in net costs incurred in Retail customer acquisition activities. Higher contribution from monitoring and service gross margin was offset by an increase in general and administrative expenses related to elevated bad debt and legal fees.

The Company’s net loss in the second quarter improved to $(2.5) million, or $(0.10) per share, from $(9.1) million, or $(0.36) per share, during the same period in 2008. Higher operating income in the second quarter of 2009 due to the aforementioned items was the primary factor in the improvement.

Non-GAAP Results

Adjusted EBITDA

Adjusted EBITDA in the second quarter of 2009 improved 10.6% to $30.0 million from $27.2 million in the second quarter of 2008. This improvement was due to increases in Retail and Wholesale monitoring and service gross margins as well as a reduction in net costs incurred in Retail customer acquisition activities, partially offset by higher general and administrative costs. The Retail reporting unit

once again lowered monitoring and service direct costs by 10% on a slightly declining revenue base, and the Wholesale reporting unit increased monitoring and service revenue by 9% while keeping costs flat.

Net Debt

On June 30, 2009, the Company had $66.8 million of cash and cash equivalents, with excess cash and cash equivalents invested primarily in short-term United States treasury portfolios. The Company also had $19.7 million available for borrowing under its revolving credit facility as of that same date.

The Company’s total debt and capital leases, excluding debt premiums, was $520.3 million as of June 30, 2009, compared to $522.6 million as of December 31, 2008.

During the second quarter of 2009, the Company’s Net Debt decreased $16.6 million to $453.5 million due to lower working capital requirements, higher adjusted EBITDA, and fewer opportunities to invest in new customers within our targeted range of economic returns.

Recurring Monthly Revenue and Attrition

The Company’s Retail reporting unit ended the second quarter of 2009 with RMR of $20.3 million, or 1.3% lower than one year earlier. Annualized net Retail attrition in the second quarter of 2009 rose to 10.4% from 9.4% in the second quarter of 2008. Attrition on the commercial customer base was higher due to its sensitivity to the economic downturn. The Retail reporting unit added $456,000 of RMR in the second quarter of 2009 compared to $608,000 a year ago. As previously reported, the Company expects total RMR additions in 2009 to be lower than additions in 2008 in part because of reduced investment opportunities due to economic conditions as well as the Company’s disciplined approach to investing in new customers. Net costs incurred related to RMR additions were $12.8 million in the second quarter of 2009 compared to $17.7 million for the same period in 2008. The Wholesale reporting unit ended the second quarter of 2009 with $4.1 million of RMR, up from $4.0 million one year earlier, attributable to growth in its largest customers. Annualized Wholesale attrition in the second quarter was 26.1% compared to 24.5% in the second quarter of 2008 due to the cancellation of a large customer. Wholesale RMR is subject to significant change depending on the decisions of its largest customers.

RMR as of June 30, 2009 at the Company’s Multifamily reporting unit was $2.0 million compared to $2.4 million one year earlier as several large customers have elected to cancel services due to their financial hardships. In addition, given the challenging environment for multifamily properties, the Company decided last year to focus its Multifamily reporting unit on serving and upgrading existing customers rather than on actively pursuing growth from new customers.

Recurring Monthly Revenues (RMR)

RMR is the sum of all the monthly revenue we are entitled to receive under contracts with customers in effect at the end of a period.

(a) Revenue that is not pursuant to periodic contractual billings

The Company believes the presentation of RMR is useful to investors because the measure is widely used in the industry to assess the amount of recurring revenues from customer fees produced by a monitored security alarm company such as Protection One, Inc. Management monitors RMR, among other things, to evaluate the Company’s ongoing performance.

Adjusted EBITDA	$	30,036		$	27,167		$	59,080		$	53,918

Adjusted EBITDA is used by management and reviewed by the Board of Directors in evaluating segment performance and determining how to allocate resources across segments for investments in customer acquisition activities, capital expenditures and spending in general. The Company believes it is also utilized by the investor community which follows the security monitoring industry. Adjusted EBITDA is useful because it allows investors and management to evaluate and compare operating results from period to period in a meaningful and consistent manner in addition to standard GAAP financial measures. Specifically, Adjusted EBITDA allows the chief operating decision maker to evaluate segment results of operations, including operating performance of monitoring and service activities, effects of investments in creating new customer relationships, and sales and installation of security systems, without the effects of non-cash amortization and depreciation. This information should not be considered an alternative to any measure of performance as promulgated under GAAP, 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. See the table above for the reconciliation of Adjusted EBITDA to consolidated loss before income taxes. The Company’s calculation of Adjusted EBITDA may be different from the calculation used by other companies and comparability may be limited.

Net Debt	$	453,483		$	483,692

Net Debt is utilized by management as a measure of the Company’s financial leverage and the Company believes that investors also may find Net Debt to be helpful in evaluating the Company’s financial leverage. This supplemental non-GAAP information should be viewed in conjunction with the Company’s consolidated balance sheets in the Company’s report on Form 10-Q for the period ended June 30, 2009. While not included in Net Debt, the Company also had notes receivable due from its Wholesale dealers of approximately $3.5 million and $4.2 million as of June 30, 2009 and December 31, 2008, respectively.
