SuperMedia Announces Fourth Quarter and Full Year 2012 Results

2012 Year-end Summary

·                  Dex One merger transaction on course

·                  Operating income of $440 million and operating margin of 32.5 percent

·                  Operating revenue of $1,354 million

·                  Total debt reduced by $303 million during 2012

DALLAS — SuperMedia (NASDAQ:SPMD) today announced its financial results for the fourth quarter and full year 2012.

“Our merger with Dex One remains on track and we expect to close the transaction in the first half of 2013,” said Peter McDonald, president and CEO of SuperMedia. “The transaction represents an opportunity to improve the combined companies’ positioning for growth, quality and productivity and results in a strengthened balance sheet.

“As I look back at the last few years, I’m pleased with our efforts and results from a cost control perspective. Looking forward, we will continue to aggressively manage the new company’s cost structure, and will focus on top line results. The success of Dex Media will come down to our ability to execute on our strategy of helping businesses grow by using a complete suite of social, local and mobile marketing solutions.”

Merger Update

SuperMedia and Dex One Corporation (“Dex”) announced the execution of a definitive agreement to combine in a stock-for-stock merger of equals on August 21, 2012.(1) On March 17, 2013, each of SuperMedia and Dex and all of their domestic subsidiaries filed a voluntary “pre-packaged” bankruptcy petition in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”), each

(1)  “Dex One and SuperMedia Will Combine to Create a National Provider of Social, Local and Mobile Marketing Solutions” Press Release

seeking relief pursuant to a prepackaged plan of reorganization under the provisions of chapter 11 of title 11 of the United States Code.  The bankruptcy petition seeks the Bankruptcy Court’s approval of the prepackaged plan in order to effect the proposed merger.

The prepackaged plans are an alternative means by which to consummate the proposed merger.  Under the merger agreement, the transaction may be completed through Chapter 11 reorganization if either SuperMedia or Dex is unable to obtain its stockholders’ approval of the merger agreement or unanimous lender approval of certain amendments (the “financing amendments”) to SuperMedia’s and Dex’s respective credit agreements.

On March 13, 2013, stockholders of Dex and SuperMedia voted to approve and adopt the proposed merger in the event that both SuperMedia and Dex were able to obtain unanimous lender approval of the transaction.  Also on March 13, 2013, stockholders and lenders of Dex and SuperMedia voted to accept the prepackaged plan in the event that they were unable to obtain unanimous lender approval of the transaction and, alternatively, elected to effect the transaction through Chapter 11 cases.

Neither Dex nor SuperMedia obtained the unanimous lender approval required to effect the transaction outside of court.  Accordingly, on March 17, 2013, SuperMedia’s board of directors authorized SuperMedia management to file a voluntary bankruptcy petition in order to seek approval of the prepackaged plan and the completion of the merger.

There can be no assurance that the Bankruptcy Court will confirm the prepackaged plans in a timely manner.  While operating under bankruptcy, the Company’s operations will be subject to oversight by the Bankruptcy Court, which could lead to uncertainties as to the realization of assets and satisfaction of obligations in the normal course of business.

Basis of Presentation and Non-GAAP Financial Measures

For the readers’ convenience, the financial information accompanying this release provides a reconciliation of GAAP to non-GAAP and adjusted non-GAAP results.  SuperMedia believes that the use of non-GAAP financial measures provides useful information to investors to gain an overall understanding of its current financial performance. Specifically, SuperMedia believes the non-GAAP results provide useful information to both management and investors by excluding certain expenses, gains and losses that SuperMedia believes are not indicative of its core operating results. In addition, non-GAAP financial measures are used by management for budgeting and forecasting as well as subsequently measuring SuperMedia’s performance, and SuperMedia believes that it is providing investors with financial measures that most closely align to its internal measurement processes.

We believe that these factors include, but are not limited to, the risks related to the following:

(3)  Advertising sales for the nine months ended December 31, 2011 include negative adjustments of $11 million, related to the financial distress and operational wind down of a single certified marketing representative in our third-party national sales channel.  Excluding this impact, advertising sales for the nine months ended December 31, 2012 would have reflected a decline of 19.5 percent.  As of June 2011, these accounts were transitioned to other certified marketing representative firms.

·                  the potential adverse impacts of failure to complete, or delay in completing, the proposed merger with Dex One Corporation (“Dex One”) as a result of obtaining consents from the stockholders and secured creditors of Dex One or the Company;

·                  the business uncertainties and contractual restrictions arising from the timing and closing of the proposed merger with Dex One, including the possible inability to consummate the proposed merger on the terms originally contemplated;

·                  the risk that anticipated cost savings, growth opportunities and other financial and operating benefits as a result of the proposed merger may not be realized or may take longer to realize than expected;

·                  the risk that benefits from the transaction may be significantly offset by costs incurred in integrating Dex One and the Company;

·                  difficulties in connection with the process of integrating Dex One and the Company if the transaction with Dex One is consummated, including: coordinating geographically separate organizations; integrating business cultures, which could prove to be incompatible; difficulties and costs of integrating information technology systems; and the potential difficulty in retaining key officers and personnel;

·                  the risks related to the impact either Dex One’s or the Company’s voluntary case under Chapter 11 of title 11 of the United States Code (the “Bankruptcy Code”) to consummate the proposed merger (together, “Chapter 11 cases”) could have on the Company’s business operations, financial condition, liquidity or cash flow;

·                  the risks related to other parties objecting to the Chapter 11 cases and the resulting cost and expenses of delays in either Chapter 11 case;

·                  risks that the combined company will incur significant, non-recurring costs in connection with the administration of the Chapter 11 cases;

·                  our inability to provide assurance for the long-term continued viability of our business;

·                  reduced advertising spending and increased contract cancellations by our clients, which causes reduced revenue;

·                  competition from other yellow pages directory publishers and other traditional and new media;

·                  our ability to anticipate or respond to changes in technology and user preferences;

·                  limitations on our operating and strategic flexibility and the ability to operate our business, finance our capital needs or expand business strategies under the terms of our credit agreement;

·                  failure to comply with the financial covenants and other restrictive covenants in our credit agreement;

·                  limited access to capital markets and increased borrowing costs resulting from our leveraged capital structure and debt ratings;

·                  changes in the availability and cost of paper and other raw materials used to print our directories;

·                  our reliance on third-party providers for printing, publishing and distribution services;

·                  credit risk associated with our reliance on small- and medium-sized businesses as clients;
