The combination of one of the country’s largest pharmacy benefit managers with a leading provider of specialty pharmacy services will transform Medco into the industry’s most comprehensive full-service pharmacy benefit provider, offering a broad spectrum of prescription medicines and integrated clinical services to patients on long-term therapies and support for the treatment of complex, chronic diseases. Specialty pharmacy represents one of the most dynamic and rapidly growing sectors of prescription health care, and this acquisition creates a strong platform for Medco’s future growth in this market.

“We believe the addition of Accredo’s specialty pharmacy expertise to Medco’s leading pharmacy benefit model will take the value we have already experienced from our current alliance with Accredo to the next level, providing significant benefits to our clients, members, shareholders and employees,” said David B. Snow Jr., Medco’s chairman, president and CEO. “Medco’s shareholders are expected to benefit from further top-line and bottom-line growth and the opportunities that lie ahead in this important growth market.

Added David D.

We believe manufacturers, physicians, payors and the valued patients we serve will realize considerable benefits from the combination of our offering with Medco’s sophisticated business model, overall scale and impressive client base.”

To maximize Accredo’s well-developed relationships, Medco intends to manage Accredo as an independent business, retaining its successful business model, brands, culture and focus. Medco is committed to preserving Accredo’s high-touch service model focused on excellence in patient care.

Leading Provider of Specialty Biopharmaceuticals

Medco launched its specialty pharmacy operations in February 2003. To complement its capabilities, in early 2004 Medco forged a 10-year strategic alliance with Accredo to create a single-source platform for all specialty pharmaceuticals, including Accredo’s limited distribution offerings.

Accredo’s business model encompasses drugs to treat hemophilia, immunodeficiency disorders, pulmonary arterial hypertension, respiratory syncytial virus, multiple sclerosis, growth hormone deficiency and Gaucher’s disease. Medications for these disease states are provided through Accredo’s 36 branch locations or shipped overnight from four centralized dispensing facilities to patient homes, physician offices and hospital outpatient departments. Medco, which now has approximately 30 million members with access to Medco Specialty Pharmacy Services, plans to cross-sell the enhanced offering across its book of business to the benefit of Medco clients.

“Our business alliance with Accredo over the past year made clear the advantages of working even more closely together, and the timing was right to make that happen now. From the pills and capsules of traditional pharmacy to the injectables and biotech medicines of specialty pharmacy, this enhances Medco’s end-to-end leadership in the management of the full pharmacy spectrum for our clients and their members,” said Snow.

Lehman Brothers Inc. served as Medco’s financial advisor and Sullivan & Cromwell LLP provided legal advice; Raymond James Financial, Inc. represented Accredo in the transaction and Alston & Bird LLP acted as Accredo’s legal counsel.
