Dex One Corporation Reports Second Quarter 2010 Results

• Adjusted EBITDA of $212 Million
• Adjusted Free Cash Flow of $140 Million
• Repaid $150 million of debt
• Updating 2010 Guidance

CARY, N.C.--(BUSINESS WIRE)--August 5, 2010--Dex One Corporation (NYSE: DEXO), a leading provider of marketing solutions for local businesses, today announced its second quarter results and updated full year 2010 guidance as follows:

FULL YEAR 2010 GUIDANCE
	Combined Adjusted Figures / Statistical Measures
Metric	Current	Prior(1)
Advertising sales decline YoY	14.5% to 15.5%	12% to 15%
Net revenue(2,3)	$1.8 Bn	$1.8 Bn
EBITDA(2,3)	$775mm to $800mm	$750mm
Free Cash Flow(2,3)	$500mm to $525mm	$450mm

1) Guidance most recently provided on May 6, 2010.

2) These are non-GAAP financial measures. Please see the discussion of non-GAAP financial measures in the schedules and related footnotes at the end of this press release.

3) The midpoint for the current outlook for net revenue, operating loss and cash flow from operations is $0.8 billion, $140 million and $450 million, respectively.

“During the second quarter, slowly stabilizing local business conditions led to improved renewal and new business trends and lower bad debt,” said Steven M. Blondy, Executive Vice President and CFO of Dex One Corporation. “Although our strict credit policies may have negatively impacted ad sales results, particularly as economic conditions deteriorated last year, the benefits of our strong receivables portfolio are clearly evident in recent write-off trends.”

Blondy continued, “Ad sales trends in the second quarter were better than the first quarter, as selling conditions slowly recovered. We now expect full year 2010 ad sales to decline near or slightly below the bottom end of our previous guidance range. However, we are increasing guidance for both 2010 EBITDA and cash flow, largely due to improved bad debt and continued cost discipline. We also remain focused on expanding our interactive offerings and paying down debt.”

SECOND QUARTER RESULTS SUMMARY
Metric	Amount (in millions)
Advertising sales	$449
Advertising sales decline YoY	13%
Adjusted net revenue(1,2)	$452
Adjusted EBTIDA(1,2)	$212
Adjusted free cash flow(1,2)	$140

1) These are non-GAAP financial measures. Please see the discussion of non-GAAP financial measures in the schedules and related footnotes at the end of this press release.

2) GAAP net revenue, net loss and cash flow from operations in the quarter were $161 million, $770 million and $135 million, respectively.

During the full quarter, Dex One repaid $150 million of debt. As of June 30, 2010, adjusted net debt was $2,960 million and the Company’s cash balance was $122 million.

During the second quarter, Dex One Corporation recorded a goodwill impairment charge of approximately $750 million, primarily triggered by the decline in the market value of the Company’s debt and equity securities.

The adoption of fresh start accounting also had a significant impact on the Company’s reported results commencing on February 1, 2010. These reported results are not indicative of our underlying operating and financial performance and are not comparable to any prior period presentation. As of June 30, 2010, adjusted net debt added back $106 million of fresh start accounting fair value discount. More information can be found in the accompanying schedules and schedule footnotes.

W. Kirk Liddell, a member of the executive oversight committee and the Company's interim principal executive officer stated, “During this leadership transition, Dex One continues to advance its priorities and focus on execution. The Company continues to move forward with a variety of initiatives related to marketing solutions, client support and sales.”

Liddell continued, “We believe Dex One has great people and service strengths. It is well positioned to provide highly effective marketing solutions to local businesses in an increasingly fragmented and complex marketplace. The search committee is working diligently to find a business leader, who will enable the Company to reach its full potential. We are confident the new CEO will find a strong, capable organization that will succeed over the long term.”

Important information regarding operating results and related reconciliations of non-GAAP financial measures to the most comparable GAAP measures can be found in the schedules and related footnotes to this press release, which should be thoroughly reviewed. All figures are preliminary and subject to change pending the filing of our Quarterly Report on Form 10-Q. Advertising sales is a statistical measure and consists of sales of advertising in print directories distributed during the period and Internet-based products and services with respect to which such advertising first appeared publicly during the period. It is important to distinguish advertising sales from net revenue, which is recognized under the deferral and amortization method.

UNAUDITED ADJUSTED STATEMENT OF OPERATIONS AND
UNAUDITED CONDENSED CONSOLIDATED STATEMENT OF OPERATIONS	Schedule 3
Fresh Start and Other Adjustments
The Company adopted fresh start accounting and reporting effective February 1, 2010, the Fresh Start Reporting Date. The financial statements as of the Fresh Start Reporting Date will report the results of Dex One with no beginning retained earnings or accumulated deficit. Any presentation of Dex One represents the financial position and results of operations of a new reporting entity and is not comparable to prior periods presented by the Predecessor Company. The financial statements for periods ended prior to the Fresh Start Reporting Date do not include the effect of any changes in our capital structure or changes in the fair value of assets and liabilities as a result of fresh start accounting. As a result of the deferral and amortization method of revenue recognition, recognized advertising revenues reflect the amortization of advertising sales consummated in prior periods as well as in the current period. The adoption of fresh start accounting has a significant impact on the financial position and results of operations of the Company subsequent to the Fresh Start Reporting Date. Fresh start accounting precludes us from recognizing deferred revenue of $290.9 million and $546.0 million and certain deferred expenses of $62.3 million and $119.2 million during the three and five months ended June 30, 2010 associated with directories that published prior to the Fresh Start Reporting Date. Thus, our reported results for the three and five months ended June 30, 2010 are not indicative of our underlying operating and financial performance and are not comparable to any prior period presentation. Accordingly, management has provided a non-GAAP presentation of “Adjusted" and "Adjusted" results for the three and six months ended June 30, 2010, respectively, on Schedules 3 and 4. Management believes that these non-GAAP financial measures are important indicators of our operations because they exclude items that may not be indicative of, or related to, our core operating results, and provide a better baseline for analyzing our underlying business. Adjusted results adjusts GAAP results of the Company for the three months ended June 30, 2010 to (i) eliminate the fresh start accounting impact on revenue and certain related expenses noted above and (ii) exclude cost-uplift recorded under fresh start accounting of $3.3 million and $5.1 million for the three and five months ended June 30, 2010. Combined Adjusted results (1) combines GAAP results of the Company for the five months ended June 30, 2010 and GAAP results of the Predecessor Company for the one month ended January 31, 2010 and (2) adjusts these combined amounts to (i) eliminate the fresh start accounting impact on revenue and certain related expenses noted above and (ii) exclude cost-uplift recorded under fresh start accounting.
Deferred directory costs, such as print, paper, distribution and commissions, relate to directories that have not yet been published and have been recorded at fair value, determined as (a) the estimated billable value of the published directory less (b) the expected costs to complete the directory, plus (c) a normal profit margin. This incremental fresh start accounting adjustment to step up the recorded value of the deferred directory costs to fair value is hereby referred to as “cost-uplift.”
Cost-uplift will be amortized over the terms of the applicable directories, not to exceed twelve months. Management believes that the non-GAAP presentation of Adjusted and Combined Adjusted results will help financial statement users better understand the material impact fresh start accounting has on the Company’s results of operations for the three and five months ended June 30, 2010 and also offers a non-GAAP normalized comparison to GAAP results of the Predecessor Company for the three and six months ended June 30, 2009. The non-GAAP Adjusted and Combined Adjusted results are reconciled to the most comparable GAAP measures. While the non-GAAP Adjusted and Combined Adjusted results exclude the effects of fresh start accounting and certain other items, such as goodwill and intangible asset impairment charges, it must be noted that the non-GAAP Adjusted and Combined Adjusted results are not strictly comparable to the Predecessor Company’s GAAP results for the three and six months ended June 30, 2009 and should not be treated as such. We strongly encourage investors and stockholders to review our financial statements and publicly filed reports in their entirety and not rely on any single financial measure.

RECONCILIATION OF NON-GAAP MEASURES	Schedule 7a
(unaudited)
EBITDA, Adjusted EBITDA and Combined Adjusted EBITDA are not measurements of operating performance computed in accordance with GAAP and should not be considered as a substitute for net income (loss) prepared in conformity with GAAP. In addition, EBITDA may not be comparable to similarly titled measures of other companies. Management believes that these non-GAAP financial measures are important indicators of our operations because they exclude items that may not be indicative of, or related to, our core operating results, and provide a better baseline for anlayzing our underlying business. Adjusted EBITDA of the Successor Company for the three and five months ended June 30, 2010 is determined by adjusting EBITDA to (i) eliminate the fresh start accounting impact on revenue and certain expenses (ii) exclude the impact of cost-uplift recorded under fresh start accounting, (iii) exclude the goodwill and intangible asset impairment charges during the three months ended June 30, 2010 and for (iv) stock-based compensation expense and long-term incentive program. Adjusted EBITDA of the Predecessor Company for the one month ended January 31, 2010 is determined by adjusting EBITDA for (i) reorganization items, net and (ii) stock-based compensation expense and long-term incentive program. Adjusted EBITDA of the Predecessor Company for the three and six months ended June 30, 2009 is determined by adjusting EBITDA for items such as (i) stock-based compensation expense and long-term incentive program, (ii) restricted stock unit expense related to the Business.com Acquisition, (iii) restructuring costs, and (iv) reorganization items, net. Combined adjusted EBITDA for the six months ended June 30, 2010 combines the adjusted EBITDA of the Successor Company for the five months ended June 30, 2010 and the Predecessor Company for the one month ended January 31, 2010.

RECONCILIATION OF NON-GAAP MEASURES (cont'd)	Schedule 7c
(unaudited)
Adjusted cash flow from operations, Adjusted free cash flow and Combined Adjusted free cash flow are not measurements of operating performance computed in accordance with GAAP and should not be considered as a substitute for cash flow from operations prepared in conformity with GAAP. In addition, Adjusted cash flow from operations, Adjusted free cash flow and Combined Adjusted free cash flow may not be comparable to similarly titled measures of other companies. Management believes that these adjusted cash flow measures provide investors and stockholders with a relevant measure of liquidity and a useful basis for assessing the Company's ability to fund its activities and obligations. Adjusted cash flow from operations of the Successor Company for the three and five months ended June 30, 2010 and Predecessor Company for the one month ended January 31, 2010 is determined by adjusting cash flow from operations - GAAP for cash reorganization payments.
Adjusted cash flow from operations of the Predecessor Company for the three and six months ended June 30, 2010 is determined by adjusting cash flow from operations - GAAP for (i) cash reorganization payments, (ii) cash restructuring payments and (iii) cash restricted stock unit payments related to the Business.com Acquisition. Adjusted free cash flow is determined by subtracting additions to fixed assets and computer software - GAAP from Adjusted cash flow from operations. Combined Adjusted free cash flow for the six months ended June 30, 2010 combines the Adjusted free cash flow of the Successor Company for the five months ended June 30, 2010 and the Predecessor Company for the one month ended January 31, 2010.

See accompanying Notes to Unaudited Condensed Consolidated Financial Statements and Non-GAAP Measures - Schedule 9.
Note: These schedules are preliminary and subject to change pending the Company's filing of its Form 10-Q.

(1) Our advertising revenues are earned primarily from the sale of advertising in yellow pages directories that we publish. Revenue from the sale of such advertising is deferred when a directory is published, net of estimated sales claims, and recognized ratably over the life of a directory, which is typically 12 months. Advertising revenues also include revenues for Internet-based advertising products, including our proprietary local search site DexKnows.com and DexNet. Revenues with respect to our Internet-based advertising products that are sold with print advertising are initially deferred until the service is delivered or fulfilled and recognized ratably over the life of the contract. Revenues with respect to Internet-based services that are not sold with print advertising are recognized as delivered or fulfilled.

(2) Based upon the decline in the trading value of our debt and equity securities during the three months ended June 30, 2010 and the retirement of our Chairman and Chief Executive Officer on May 28, 2010, among others, the Company concluded that there were indicators of impairment during the three months ended June 30, 2010. As a result of identifying indicators of impairment, we performed impairment tests as of June 30, 2010 of our goodwill, definite-lived intangible assets and other long-lived assets in accordance with Accounting Standards Codification ("ASC") 350, Intangibles – Goodwill and Other and ASC 360, Property, Plant and Equipment. The testing results of our definite-lived intangible assets and other long-lived assets resulted in an impairment charge of $17.3 million during the three months ended June 30, 2010 associated with trade names and trademarks, technology, local customer relationships and other from our Business.com reporting unit. The testing results of our goodwill resulted in an impairment charge of $752.3 million during the three months ended June 30, 2010, which as been recorded at each of our reporting units. The Company has excluded the goodwill and intangible asset impairment charges from Adjusted Results for the three months ended June 30, 2010 and Combined Adjusted Results for the six months ended June 30, 2010.

(3) Reorganization items directly associated with the process of reorganizing the business under Chapter 11 of the Bankruptcy Code have been recorded on a separate line item on the unaudited condensed consolidated statements of operations. The Predecessor Company has recorded $7.8 billion of reorganization items during the one month ended January 31, 2010 associated with the gain on reorganization/settlement of liabilities subject to compromise and the impact of fresh start accounting adjustments. The Predecessor Company has recorded $70.8 million of reorganization items during the three and six months ended June 30, 2009 associated with professional fees, the write-off of unamortized deferred financing costs, net premiums/discounts and fair value adjustments due to purchase accounting associated with long-term debt classified as liabilities subject to compromise, and rejected leases. Additionally, liabilities are segregated between liabilities not subject to compromise and liabilities subject to compromise on the unaudited condensed consolidated balance sheet at December 31, 2009. The Predecessor Company's senior notes, senior discount notes and senior subordinated notes have been classified as liabilities subject to compromise at December 31, 2009 and the Predecessor Company's credit facilities have been excluded from liabilities subject to compromise at December 31, 2009.

(4) In conjunction with our adoption of fresh start accounting, an adjustment was established to record our outstanding debt at fair value on the Fresh Start Reporting Date. The Company was required to record our amended and restated credit facilities at a discount as a result of their fair value on the Fresh Start Reporting Date. Therefore, the carrying amount of these debt obligations is lower than the principal amount due at maturity. This fair value adjustment is amortized as an increase to interest expense over the remaining term of the respective debt agreements and does not impact future scheduled interest or principal payments. The unamortized fair value adjustment resulting from fresh start accounting was $106.4 million at June 30, 2010.

(5) Net debt represents total debt less cash and cash equivalents on the respective date. Net debt – eliminating fair value discount eliminates the fair value discount as a result of fresh start accounting described in Note 4 and represents principal amounts due at maturity. Net debt as of December 31, 2009 excludes $6.1 billion of long-term debt classified as liabilities subject to compromise on the audited selected balance sheet data.

(6) Advertising sales is a statistical measure and consists of sales of advertising in print directories distributed during the period and Internet-based products and services with respect to which such advertising first appeared publicly during the period. It is important to distinguish advertising sales from net revenue, which is recognized under the deferral and amortization method. Combined advertising sales for the six months ended June 30, 2010 combines advertising sales of the Successor Company for the five months ended June 30, 2010 and the Predecessor Company for the one month ended January 31, 2010. Combined advertising sales for the three months ended March 31, 2010 combines advertising sales of the Successor Company for the two months ended March 31, 2010 and the Predecessor Company for the one month ended January 31, 2010.

Appendix

GAAP Reconciliations – Fresh Start And Other Adjustments The Company adopted fresh start accounting and reporting effective February 1, 2010, the Fresh Start Reporting Date. The financial statements as of the Fresh Start Reporting Date will report the results of Dex One with no beginning retained earnings or accumulated deficit. Any presentation of Dex One represents the financial position and results of operations of a new reporting entity and is not comparable to prior periods presented by the Predecessor Company. The financial statements for periods ended prior to the Fresh Start Reporting Date do not include the effect of any changes in our capital structure or changes in the fair value of assets and liabilities as a result of fresh start accounting. As a result of the deferral and amortization method of revenue recognition, recognized advertising revenues reflect the amortization of advertising sales consummated in prior periods as well as in the current period. The adoption of fresh start accounting has a significant impact on the financial position and results of operations of the Company subsequent to the Fresh Start Reporting Date. Fresh start accounting precludes us from recognizing deferred revenue of $290.9 million and $546.0 million and certain deferred expenses of $62.3 million and $119.2 million during the three and five months ended June 30, 2010 associated with directories that published prior to the Fresh Start Reporting Date. Thus, our reported results for the three and five months ended June 30, 2010 are not indicative of our underlying operating and financial performance and are not comparable to any prior period presentation. Accordingly, management has provided a non-GAAP presentation of “Adjusted" and "Combined Adjusted" results for the three and six months ended June 30 2010 respectively on Schedules 3 and 4 30, 2010, respectively, 4. Management believes that these non-GAAP financial measures are important indicators of our operations because they exclude items that may not be indicative of, or related to, our core operating results, and provide a better baseline for analyzing our underlying business. Adjusted results adjusts GAAP results of the Company for the three months ended June 30, 2010 to (i) eliminate the fresh start accounting impact on revenue and certain related expenses noted above and (ii) exclude cost-uplift recorded under fresh start accounting of $3.3 million and $5.1 million for the three and five months ended June 30, 2010. Combined Adjusted results ( 1) combines GAAP results of the Company for the five , j ) p y months ended June 30, 2010 and GAAP results of the Predecessor Company for the one month ended January 31, 2010 and (2) adjusts these combined amounts to (i) eliminate the fresh start accounting impact on revenue and certain related expenses noted above and (ii) exclude costuplift recorded under fresh start accounting. Deferred directory costs, such as print, paper, distribution and commissions, relate to directories that have not yet been published and have been recorded at fair value, determined as (a) the estimated billable value of the published directory less (b) the expected costs to complete the directory, plus (c) a normal profit margin. This incremental fresh start accounting adjustment to step up the recorded value of the deferred directory costs to fair value is hereby referred to as “cost-uplift.” 12

GAAP Reconciliations – Fresh Start And Other Adjustments cont’d) Cost-uplift will be amortized over the terms of the applicable directories, not to exceed twelve months. Management believes that the non-GAAP presentation of Adjusted and Combined Adjusted results will help financial statement users better understand the material impact fresh start (cont d) accounting has on the Company’s results of operations for the three and five months ended June 30, 2010 and also offers a non-GAAP normalized comparison to GAAP results of the Predecessor Company for the three and six months ended June 30, 2009. The non-GAAP Adjusted and Combined Adjusted results are reconciled to the most comparable GAAP measures. While the non-GAAP Adjusted and Combined Adjusted results exclude the effects of fresh start accounting and certain other items, such as goodwill and intangible asset impairment charges, it must be noted that the non-GAAP Adjusted and Combined Adjusted results are not strictly comparable to the Predecessor Company’s GAAP results for the three and six months ended June 30, 2009 and should not be treated as such. We strongly encourage investors and stockholders to review our financial statements and publicly filed reports in their entirety and not rely on any single financial measure. 13
