PROTECTION ONE ANNOUNCES FOURTH QUARTER AND
FULL YEAR 2006 RESULTS

Company completes eventful year including growth in total RMR, special dividend, merger agreement with IASG

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

LAWRENCE, Kan., March 16, 2007 — Protection One, Inc. (OTCBB: PONN), one of the leading providers of security monitoring services in the United States, today reported financial results for the fourth quarter and full year ended December 31, 2006.

Richard Ginsburg, Protection One’s President and CEO, commented, “I am pleased to report our first year-over-year increase in total RMR (recurring monthly revenue) in seven years.  We ended the year with $20.0 million of RMR by increasing retail additions by 10.7% while reducing retail cancels by 2.0% on a bigger average RMR base.   I believe we are well positioned to consummate a merger with Integrated Alarm Services Group early in April and to tackle the related challenges of reducing costs, increasing RMR additions, lowering attrition and upgrading critical systems.  We look forward to an exciting year.”

Fourth Quarter 2006 Results

Higher average RMR in the fourth quarter of 2006 allowed the Company to record monitoring and related services revenues of $61.9 million, an increase of nearly 1% from $61.3 million recorded in the fourth quarter of 2005.  Results in the fourth quarter of 2005 were adversely affected by Hurricane Katrina.

Total revenues in the fourth quarter of 2006 were $69.1 million compared to $66.5 million in the fourth quarter of 2005, an increase of 3.9%.   Modestly more sales activity and an increase in amortization of previously deferred revenues contributed to the improvement.

Net loss in the fourth quarter of 2006 was $(4.7) million, or $(0.26) per share, compared to $(2.2) million, or $(0.13) million per share, in the fourth quarter of 2005, in part due to an increase in net interest expense of $1.8 million and an increase in tax expense of $0.4 million.

The weighted average number of outstanding shares was 18,239,953 in the fourth quarter of 2006, compared to 18,198,571 in the fourth quarter of 2005.

Fiscal Year 2006 Results

Monitoring and related services revenues were $247.4 million for the year ended December 31, 2006, $26.5 million in the 39-day period commencing January 1, 2005, and ending with and including February 8, 2005 (the “pre-push down period”), and $219.5 million in the 326-day period beginning after that date and ending on December 31, 2005, utilizing the new basis of accounting (the “post-push down period”).  [See “Push-Down Accounting in 2005” below for an explanation of why the Company adopted push-down accounting in 2005 and a description of the impact of push-down accounting on the Company’s financial statements.]

Total revenues were $270.6 million in 2006 and, in the pre- and post-push down periods of 2005 were $28.5 million and $234.5 million, respectively.

Net loss was $(17.4) million, or $(0.95) per share, in fiscal 2006.  In the pre- and post-push down periods in 2005, the net loss was $(11.4) million, or $(5.80) per share, and $(15.6) million, or $(0.86) per share, respectively.

The weighted average number of outstanding shares was 18,233,221 in 2006, 18,198,571 in the post-push down period and 1,965,654 in the pre-push down period.

Recurring Monthly Revenue

As of December 31, 2006, recurring monthly revenue (RMR) was $20.0 million compared to $19.9 million as of December 31, 2005.  This RMR growth arises from increasing internally generated

retail RMR additions while maintaining and even reducing retail RMR cancellations through a heightened focus on customer care.  In the fourth quarter of 2006, the Company’s Protection One Monitoring reporting unit added approximately $0.5 million of retail RMR through internal sales efforts, 9.2% more than it added in the fourth quarter of 2005.  In fiscal 2006, the Protection One Monitoring reporting unit added approximately $2.1 million of retail RMR through internal sales efforts, 10.7% more than it added in 2005.  See “Non-GAAP Reconciliations” below for a reconciliation of RMR to reported revenue.

Customer Attrition

Excluding the benefit of move-in accounts (new residents in locations with pre-existing Company alarm systems), the customer attrition rate on a trailing 12 months basis ending December 31 for the Protection One Monitoring reporting unit (excluding wholesale accounts and losses from Hurricane Katrina) decreased to 12.3% in 2006 from 12.8% in 2005.  Attrition results in 2006 have benefited from fewer cancellations from moves as the housing market has slowed.  Attrition in 2005 was affected by a higher level of cancellations in the Company’s southeast region, some of which may be attributable to the residual effects throughout the region of heightened tropical storm activity.

Including the benefit of move-in accounts, the customer attrition rate on a trailing 12 months basis ending December 31 for the Protection One Monitoring reporting unit (excluding wholesale accounts and losses from Hurricane Katrina) decreased to 10.1% in 2006 from 10.3% in 2005.

The Company’s Network Multifamily reporting unit reported higher attrition in 2006.  The customer attrition rate on a trailing 12 months basis ending December 31 for Network Multifamily (excluding losses from Hurricane Katrina) increased to 11.9% in 2006 from 5.9% in 2005.  More contracts reached end of term in 2006 than in 2005 and Network Multifamily’s 2006 results include an adjustment for accounts believed to be at-risk of canceling.  Prior period results did not include such an adjustment.

Adjusted EBITDA

For the fourth quarter 2006, the Company achieved adjusted earnings before interest, taxes, depreciation, amortization and other items (“Adjusted EBITDA”) of $21.0 million, up slightly from $20.8

million in the same period the prior year, primarily due to growth in monitoring and service revenues in the fourth quarter of 2006 compared to the fourth quarter of 2005.

In 2006, adjusted EBITDA was $84.2 million and, in the pre- and post-push down periods in 2005 was $9.0 million and $75.9 million, respectively.  See “Non-GAAP Reconciliations” below for a reconciliation of Adjusted EBITDA to reported net loss and a discussion of certain uses and limitations related to Adjusted EBITDA.

Balance Sheet

Excluding debt discounts and premiums, the Company’s total debt outstanding, as of December 31, 2006, was $410.8 million, compared to $344.2 million as of December 31, 2005, reflecting the additional financing obtained through the senior secured credit facility for the purpose of paying a special cash distribution in May 2006.  The Company had $297.8 million outstanding under its senior secured credit facility as of December 31, 2006.

The Company’s cash and equivalents as of December 31, 2006, were $24.6 million compared to $19.9 million at December 31, 2005.

Push-Down Accounting in 2005

As previously reported, on February 8, 2005, the Company consummated a debt-for-equity exchange with affiliates of Quadrangle Group LLC that resulted in Quadrangle reducing the aggregate principal amount outstanding under the Company’s credit facility with Quadrangle by $120 million, in exchange for 16 million shares of the Company’s common stock. The issuance of the new shares, together with shares already owned by Quadrangle, resulted in Quadrangle owning approximately 97.3% of the Company’s common stock.

As a result of Quadrangle’s increased ownership interest from the February 8, 2005, debt-for-equity exchange, the Company has ‘‘pushed down’’ Quadrangle’s basis to a proportionate amount of its underlying assets and liabilities acquired, based on the estimated fair market values of the assets and liabilities. It is important to note that the “push-down” accounting adjustments did not impact cash flows.

Some results in 2006 may not be comparable to results achieved in 2005 due to the impact of the changes resulting from the push-down accounting adjustments described above.  Therefore, the income statement presentation of the Company’s results for the 12 months ended December 31, 2005, accompanying this release and to be included in the Company’s Form 10-K for the annual period ended December 31, 2006, (and in subsequent filings) separates the Company’s 2005 results into two periods:  (1) the 39-day period commencing January 1, 2005, and ending with and including the February 8, 2005, consummation of the debt-for-equity exchange, and (2) the 326-day period beginning after that date and ending on December 31, 2005, utilizing the new basis of accounting.

Non-GAAP Reconciliations

Adjusted EBITDA

The Company’s management uses adjusted EBITDA  in evaluating operating performance and allocating resources, and management believes it is used by many analysts who follow the security industry.  Management also believes that presentation of Adjusted EBITDA with standard GAAP financial measures is useful because such measures collectively allow investors and management to evaluate and compare the Company’s operating results from period to period in a meaningful manner.  Adjusted EBITDA 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 income (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. For example, Adjusted EBITDA does not reflect historical or future interest expense; principal payments; changes in working capital needs; cash requirements for acquiring new customers, replacing certain assets that are being depreciated or amortized, or other capital expenditures; or certain event-related expenses such as change in control, debt restructuring, consolidation, employee retention or sale-related expenses.  Accordingly, Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of the Company’s results as reported under GAAP.  The Company’s calculation of Adjusted EBITDA may be different from the calculation

used by other companies and comparability may be limited.  See the table below for the reconciliation of Adjusted EBITDA to consolidated loss before income taxes.

Recurring Monthly Revenue

The Company believes the presentation of recurring monthly revenue is useful to investors because the measure is often used by investors and lenders to evaluate companies such as Protection One with recurring revenue streams.  Management monitors recurring monthly revenue, among other things, to evaluate the Company’s ongoing performance.

The table below reconciles recurring monthly revenue to revenues reflected on the consolidated statements of operations (information for the period January 1, 2005 through February 8, 2005 was not considered to be material in a comparison of RMR as of fiscal year end and therefore has not been presented).
