Alkermes Announces Restructuring

Alkermes, Inc. (NASDAQ: ALKS) announced that it is restructuring its operations following the termination by Eli Lilly and Company (Lilly) of the AIR® Insulin program, as announced March 7, 2008. With this restructuring, Alkermes is reducing its workforce by approximately 150 employees and closing its AIR commercial manufacturing facility in Chelsea, MA. The company is taking these actions based on its current expectations of the financial impact of Lilly's termination of the AIR Insulin program. "We are implementing a new operational cost structure to align our expenses with near-term revenues, which we anticipate will be lower than expected due to Lilly's termination of the inhaled insulin program," stated David Broecker, president and CEO of Alkermes. "The flexibility of our business model allows us to adapt our cost structure while maintaining our ability to develop innovative products of our own." The reduction in workforce, effective this week, represents approximately 18% of the company’s total workforce. Employees affected by the restructuring will be eligible for a severance package that includes severance pay, continuation of benefits and outplacement services. "Alkermes’ financial foundation remains strong, and we are focused on maintaining this strength moving forward," commented David Broecker. "Lilly's termination of the program forced us to make difficult choices about the optimal size of the organization. We acknowledge the outstanding contributions that these employees have made, and I wish to express my sincere thanks for their hard work." Alkermes does not anticipate any expense savings as a result of the restructuring in fiscal 2008, ending March 31, 2008. The company expects to take a restructuring charge in the fourth quarter of fiscal 2008 in the range of $5 million to $10 million associated with the reduction in workforce and facility-related expenses. In addition, the company expects to take an impairment charge of up to $15 million in the fourth quarter of fiscal 2008 related to fixed assets at the Chelsea facility. Alkermes expects cost savings from the restructuring in the range of $15 million to $20 million in fiscal 2009 and will provide more detailed financial expectations for fiscal 2009 in May. As of December 31, 2007, Alkermes reported cash and total investments of $516.6 million.
