Magellan Health Reports Second Quarter 2015 Financial Results

Scottsdale, Ariz. — July 27, 2015 — Magellan Health, Inc. (NASDAQ: MGLN) today reported financial results for the second quarter of 2015, as summarized below. The company reported net revenue of $1,157.6 million, segment profit of $53.2 million, and net income of $4.6 million, or $0.17 per diluted share. In addition, the company reported adjusted net income of $14.7 million and adjusted earnings per share of $0.56.

Second Quarter Financial Results*

Variances for three months ended June 30, 2015 vs. June 30, 2014:

·                  The increase in revenue between periods resulted primarily from the inclusion of revenues from acquired entities, the impact of new business, and same store growth and rate increases, which were partially offset by the loss of revenues associated with previously announced contract terminations.

·                  The increase in segment profit between periods is primarily due to new business, same store growth, and the impact of acquisitions, which were partially offset by previously announced contract terminations.

·                  The increase in adjusted net income between periods is mainly due to increased segment profit.

·                  The decrease in net income between periods is primarily due to higher non-cash expenses relating to acquisitions, partially offset by higher segment profit.

As of June 30, 2015, the company had unrestricted cash and investments of $270.6 million.

* Refer to the Basis of Presentation for a discussion of non-GAAP financial measures.

“Our results for this quarter reflect strong performance from our Pharmacy segment, solid results in Specialty Solutions, and some weakness in care results in the Commercial and Public Sector segments. We have plans in place to address these issues, and expect that the results will improve in the second half of the year,” said Barry M. Smith, chairman and chief executive officer of Magellan Health.

“The recent reorganization of the company into two business units — Magellan Healthcare and Magellan Rx Management - provides a unified approach to customers for our entire suite of healthcare products. This improved alignment will help drive enhanced services and solutions, as well as administrative efficiencies. This enables us to better align our resources across the enterprise in support of our health plan, employer and government clients.”

Results and Outlook

“Relative to full year 2015, we are maintaining our guidance, with the exception of updating our EPS guidance to reflect the impact of recent share repurchase activity. We now expect fully diluted EPS to be between $1.69 and $2.28, and fully diluted adjusted EPS between $3.45 and $3.90, based on average fully diluted shares of 26.7 million. This updated fully diluted share count reflects share repurchases and option exercises through July 22, 2015, but excludes any potential future activity.

“Compared to the first half of 2015, we expect the second half of the year to produce stronger earnings due to improved results in Magellan Complete Care, mainly driven by care management initiatives, network recontracting, and rates; the impact of business growth, primarily in our Pharmacy Management segment; and the seasonality and timing of care results and customer settlements across our businesses. We expect an increasing pattern of earnings over each of the last two quarters of the year.”

Basis of Presentation

In addition to results determined under GAAP, Magellan provides certain non-GAAP financial measures that management believes are useful in assessing the Company’s performance. Following is a description of these important non-GAAP measures.

Segment profit is equal to net revenues less the sum of cost of care, cost of goods sold, direct service costs and other operating expenses, and includes income from unconsolidated subsidiaries, but excludes segment profit or loss from non-controlling interests held by other parties, stock compensation expense, as well as changes in the fair value of contingent consideration recorded in relation to acquisitions.

Adjusted net income and adjusted earnings per share reflect certain adjustments made for acquisitions completed after January 1, 2013 to exclude non-cash stock compensation expense resulting from restricted stock purchases by sellers, as well as amortization of identified acquisition intangibles and changes in the fair value of contingent consideration recorded in relation to acquisitions.

Included in the tables issued with this press release are the reconciliations from non-GAAP measures to the corresponding GAAP measures.
