AmerisourceBergen Provides Quarterly Financial Information for PharMerica Segment and Clarifies Guidance

October 16, 2007
Company to Report Fourth Quarter & Fiscal Year 2007 Results on November 1, 2007

The PharMerica Segment financial information for all four quarters in fiscal year 2006 and the first three quarters of fiscal year 2007 is provided in an 8-K Report which the Company filed with the Securities and Exchange Commission this afternoon and is available in the Investors Section of its website, www.amerisourcebergen.com.

The Company had planned to report its institutional pharmacy business, PharMerica Long-Term Care, as a discontinued operation to reflect the recent spin-off of this business. However, following a further review of the accounting rules concerning discontinued operations, the Company has now determined that the institutional pharmacy business results may not be reported in discontinued operations. The Company will rename the PharMerica Segment as Other, which will include the historical results of PharMerica Long-Term Care and PMSI through July 31, 2007, the date of the spin-off, and only the results of PMSI after the spin-off date.

Since PharMerica Long-term Care results will be reported in continuing operations, the Company expects diluted earnings per share from continuing operations for fiscal year 2007 to be in a range of $2.58 to $2.66, including $0.08 from the institutional pharmacy business through the July 31, 2007 spin-off date. This range implies September quarter diluted earnings per share from continuing operations in the range of $0.59 to $0.67, which includes a $0.01 contribution from the institutional pharmacy business. Diluted earnings per share from continuing operations for the first nine months of fiscal year 2007 were $1.99. The Company also remains optimistic about fiscal year 2008 and continues to expect its performance to be in line with its long-term financial goals.

The Company plans to release its results for the fourth quarter and 2007 fiscal year end on Thursday, November 1, 2007 prior to the opening of trading on the New York Stock Exchange. The Company will host a conference call to discuss the results at 11:00 a.m. Eastern Daylight Time on November 1, 2007.
