DUBLIN--(BUSINESS WIRE)--Jul. 26, 2012-- Alkermes plc (NASDAQ: ALKS) today reported financial results for its first quarter of fiscal 2013, which ended June 30, 2012, and reiterated expectations for its fiscal year 2013, which will be the first full fiscal year of the combined company, Alkermes plc (Alkermes), following the completion of the merger of Alkermes, Inc. with Elan Drug Technologies (EDT) on Sept. 16, 2011.

"Our first quarter results highlight Alkermes' transformation to a business generating growing revenues and earnings. These results also demonstrate the strength of our business model with revenues coming from a diversified portfolio of important medications," commented Richard Pops, Chief Executive Officer of Alkermes. "Our company is in a stronger position than ever before with solid financial performance and a broad portfolio of unique commercial and pipeline products."

First Quarter Fiscal 2013 Highlights

• Total revenues for the first quarter increased 146% to $152.2 million, which reflected the expansion of the company's commercial product portfolio as a result of the merger and the inclusion of $20.0 million of intellectual property license revenue unrelated to our key clinical development programs. This compared to total revenues of $61.9 million for the same period in the prior fiscal year for Alkermes, Inc.
• Based on accounting principles generally accepted in the U.S. (GAAP), Alkermes reported net income of $22.4 million, or a basic and diluted earnings per share (EPS) of $0.17, for the quarter. This compared to a GAAP net loss of $13.2 million, or a basic and diluted loss per share of $0.14, for the same period in the prior fiscal year for Alkermes, Inc.
• The company reported non-GAAP¹ net income of $53.0 million, or a non-GAAP diluted EPS of $0.39. This compared to non-GAAP net income of $3.6 million, or a non-GAAP diluted EPS of $0.04, for the same period in the prior fiscal year for Alkermes, Inc.

"The business is performing as we expected with growing revenue streams from our key commercial products and continued contributions from the legacy portfolio during the quarter. For the remainder of the fiscal year, we expect to see growing contributions from the key products while contributions from the legacy products become less significant," commented James Frates, Chief Financial Officer of Alkermes. "Looking forward, we see the business on a steady course for achieving the financial expectations for fiscal year 2013 that we set forth in May."

This compared to $48.5 million in manufacturing and royalty revenues from RISPERDAL CONSTA alone for the same period of fiscal 2012, which were driven by unusually high manufacturing revenues due to the timing of shipments. Worldwide end-market sales of RISPERDAL CONSTA and INVEGA SUSTENNA/XEPLIONfor the first quarter of fiscal 2013 were approximately $550 million and grew more than 14% year-over-year.
• Manufacturing and royalty revenues from AMPYRA^®/FAMPYRA^®2 were $17.1 million for the first quarter of fiscal 2013. Alkermes, Inc.did not record anyrevenues from AMPYRA/FAMPYRA for the same period of fiscal 2012.

Costs and Expenses

• Operating expenses for the first quarter of fiscal 2013 were $120.1 million. This compared to operating expenses of $75.8 million for the same period of fiscal 2012 for Alkermes, Inc. The increase was primarily related to the inclusion of expenses associated with the former EDT business and the advancement of pipeline candidates into later stages of development.
• Net interest expense for the first quarter of fiscal 2013 was $9.9 million, including $10.2 million of interest expense on the term loans secured to fund the merger.

Balance Sheet

• At June 30, 2012, Alkermes recorded cash and total investments of $231.9 million, compared to $246.1 million at March 31, 2012.

¹As a complement to GAAP results, the company is providing non-GAAP net income (loss) and non-GAAP diluted earnings (loss) per share, which the company believes better indicate underlying trends in ongoing operations and cash flows. Non-GAAP net income (loss) adjusts for one-time and non-cash charges by excluding from GAAP results: share-based compensation; amortization; depreciation; non-cash net interest expense; non-cash tax expense; deferred revenue; and certain other one-time items.

²AMPYRA^® (dalfampridine) Extended Release Tablets, 10 mg is developed and marketed in the U.S. by Acorda Therapeutics, Inc. and outside the U.S. by Biogen Idec, under a licensing agreement with Acorda Therapeutics, as FAMPYRA^® (prolonged-release fampridine tablets).

Use of Non-GAAP Financial Measures

We use "non-GAAP net income" as a key indicator of the underlying financial operating performance of Alkermes plc. Non-GAAP net income is not a GAAP measure of performance and is defined as net income or loss plus or minus the non-cash portion of net interest expense and provision for or benefit from income taxes, plus depreciation and amortization of costs, share-based compensation expense, deferred revenue and other nonrecurring items. We feel that non-GAAP net income provides management and investors with a better representation of the ongoing economics of the business and reflects how we manage the business internally.

This selected financial information should be read in conjunction with the consolidated financial statements and notes thereto included in Alkermes plc's Quarterly Report on Form 10-Q for the three months ended June 30, 2012, which the company intends to file in July 2012.
