FOR IMMEDIATE RELEASE

Emdeon Reports Fourth Quarter and Full Year 2012 Results

NASHVILLE, Tenn. (March 18, 2013) – Emdeon Inc., a leading provider of healthcare revenue and payment cycle management and clinical information exchange solutions, today announced financial results for the fourth quarter and year ended December 31, 2012, as summarized below:

“During the first full year following our acquisition by Blackstone, Emdeon achieved solid financial results and made tremendous progress in establishing a firm foundation for our future growth,” said George Lazenby, chief executive officer for Emdeon. “Of particular note, we saw volumes steadily improve across Emdeon’s entire business during the second half of 2012, and our pharmacy business and payment integrity solutions continued to perform very well. We are excited about continuing to execute on our growth strategy in 2013.”

Fourth quarter 2012 revenue was $300.7 million, an increase of 5.9%, compared to $283.9 million for the same period in 2011. Net loss for the fourth quarter of 2012 was $10.2 million compared to $70.0 million for the same period in 2011. This improvement in net loss compared to the corresponding prior year period was primarily due to the impact of business growth and reduced transaction costs and expenses in the fourth quarter of 2012 associated with the November 2011 acquisition of Emdeon by affiliates of Blackstone and the related financing. These two factors were partially offset by increased interest, depreciation and amortization expense in the fourth quarter of 2012 related to the Blackstone transactions.

Fourth quarter 2012 Non-GAAP Adjusted EBITDA decreased 2.0% to $78.7 million, or 26.2% of revenue, from Non-GAAP Adjusted EBITDA of $80.3 million, or 28.3% of revenue, for the comparable period in 2011. This decline was primarily due to one less business day in the fourth quarter of 2012 and additional investments in sales and other initiatives to support our growth strategy.

For the year ended December 31, 2012, revenue was $1,178.3 million compared to $1,119.6 million for 2011, an increase of 5.2%. Net loss for full year 2012 was $78.3 million compared to $36.3 million in full year 2011. The 2012 net loss was primarily due to increased interest, depreciation and amortization expense related to the Blackstone transactions, partially offset by the impact of business growth.

Full year 2012 Non-GAAP Adjusted EBITDA increased 5.3% to $316.4 million, or 26.9% of revenue, from Non-GAAP Adjusted EBITDA of $300.5 million, or 26.8% of revenue, for the comparable period in 2011. This increase was primarily due to the impact of business growth.

A reconciliation of Emdeon’s financial results determined in accordance with U.S. Generally Accepted Accounting Principles (GAAP) to certain non-GAAP financial measures has been provided in the financial statement tables included in this release to supplement its unaudited condensed consolidated financial statements presented on a GAAP basis. An explanation of these non-GAAP measures is also included below under the heading “Explanation of Non-GAAP Financial Measures.”

Explanation of Non-GAAP Financial Measures

Emdeon’s management believes that, in order to properly understand Emdeon’s short-term and long-term financial trends, investors may wish to consider the impact of certain non-cash or non-operating items, when used as a supplement to financial performance measures prepared in accordance with U.S. Generally Accepted Accounting Principles (GAAP). These items result from facts and circumstances that vary in frequency and/or impact continuing operations. In addition, management uses results of operations before such excluded items to evaluate the operational performance of Emdeon as a basis for strategic planning and as a performance evaluation metric in determining achievement of certain executive and management incentive compensation programs. Investors should consider these non-GAAP measures in addition to, and not as a substitute for, financial performance measures prepared in accordance with GAAP. In addition to the description provided below, reconciliations of GAAP to non-GAAP results are provided in the financial statement tables included in this release.

In this release, Emdeon defines Adjusted EBITDA as EBITDA (which is defined as net income before income tax provision (benefit), net interest expense and depreciation and amortization), plus certain other non-cash or non-operating items (collectively, “EBITDA Adjustments”).

To properly evaluate Emdeon’s business, Emdeon encourages investors to review the GAAP financial information included in this release, and not rely on any single financial measure to evaluate Emdeon’s business. Emdeon also strongly encourages investors to review the reconciliation of net income (loss) to the non-GAAP measure of Adjusted EBITDA. Adjusted EBITDA, as Emdeon defines it, may differ from and may not be comparable to similarly titled measures used by other companies, because Adjusted EBITDA is not a measure of financial performance under GAAP and is susceptible to varying calculations. Adjusted EBITDA calculations are also used in our credit facilities and indentures, although the adjustments used to calculate Adjusted EBITDA as used in our credit facilities and indentures vary in certain respects among such agreements and from those presented below.

Management uses Adjusted EBITDA to facilitate a comparison of Emdeon’s operating performance on a consistent basis from period to period that, when viewed in combination with Emdeon’s GAAP results, management believes provides a more complete understanding of factors and trends affecting Emdeon’s business than GAAP measures alone. Management believes this non-GAAP measure assists Emdeon’s board of directors, management, lenders and investors in comparing Emdeon’s operating performance on a consistent basis because it removes where applicable, the impact of Emdeon’s capital structure, asset base, acquisition accounting, non-cash charges and non-operating items from Emdeon’s operations.
