AmerisourceBergen Confirms Diluted EPS From Continuing Operations of $4.00 to $4.10 for FY 2005 and $0.60 to $0.65 for the December Quarter

January 11, 2005

VALLEY FORGE, Pa.--(BUSINESS WIRE)--Jan. 11, 2005--AmerisourceBergen Corporation's (NYSE:ABC), Chief Executive Officer, R. David Yost, and Senior Vice President and Chief Financial Officer, Michael D. DiCandilo, speaking at the JP Morgan Healthcare Conference in San Francisco later today, will confirm that the Company expects, as announced on December 15, 2004, diluted earnings per share from continuing operations for fiscal 2005 to be between $4.00 and $4.10. They also will affirm, as previously announced, that the Company expects diluted earnings per share from continuing operations from the recently completed December 2004 quarter to be $0.60 to $0.65. AmerisourceBergen will report its earnings for the December 2004 quarter on January 25, 2005.

The Company continues to expect operating revenue growth in fiscal year 2005 to be flat, reflecting the loss of two large customers in fiscal 2004.

"Our current estimates for diluted earnings per share from continuing operations for fiscal 2005 reflect a number of assumptions," said Yost. "We are assuming the annual pharmaceutical market growth is in the low double digits, pharmaceutical prices appreciate approximately 5 percent in the remainder of the fiscal year, our specialty pharmaceutical business grows with the pharmaceutical market, and our $500 million stock repurchase program, which is nearly 80 percent complete, is accomplished. We also expect that the Board of Directors will authorize an additional $300 million to repurchase the approximate number of shares which were issued last week to redeem the $300 million, 5 percent convertible debt."

DiCandilo said, "For FY2005, AmerisourceBergen also will benefit from lower interest expense due to recent refinancings, as well as profitability and growth initiatives in the pharmaceutical distribution business, such as our Optimiz(TM) asset optimization program and the spring renewal of our generic formulary programs with manufacturers. We also expect the added contributions from new branded manufacturer distribution agreements throughout the year."

Concluded Yost, "Fiscal 2005 is a tough transition year for AmerisourceBergen and the industry, but the future remains bright with generic opportunities ahead, the implementation of the Medicare Modernization Act in 2006, and the evolution to fee-for-service contracts with manufacturers. Given our stated assumptions, we expect to return to our long-term diluted earnings per share growth from continuing operations of 15 percent or more in the September 2005 quarter."
