ELMSFORD, N.Y.–(BUSINESS WIRE)–May. 7, 2012 — BioScrip, Inc. (NASDAQ: BIOS) (the “Company”) today announced that it has closed the sale of certain assets of its community specialty pharmacies and centralized specialty and mail service pharmacy businesses (the “Transferred Businesses”) to Walgreen Co. (NYSE, NASDAQ: WAG). The closing was effective at 11 pm CDT on May 4, 2012. The transaction represents a total deal value of approximately $225 million, including approximately $161 million in cash and retention by BioScrip of associated net working capital with a net value of approximately $64 million, based on BioScrip’s balance sheet values at March 31, 2012.

The Company will use the proceeds from the sale to focus on and expand its infusion pharmacy footprint to better serve its national customers, execute on strategic growth opportunities and pay down debt. Post-closing, BioScrip will maintain its infusion, home health, pharmacy benefit management and cash card businesses, and will continue to service its infusion patient base and managed care customers through existing BioScrip pharmacies.

“The completion of this sale is another important step forward in the execution of our strategic plan,” said Rick Smith, President and Chief Executive Officer of BioScrip. “We now can accelerate building on our infusion pharmacy platform.
