AmerisourceBergen Re-Elects Three Board Members and Reaffirms Fiscal 2010 Expectations at Annual Meeting of Stockholders

March 4, 2010

During the meeting, AmerisourceBergen's President and Chief Executive Officer, R. David Yost, gave an overview of the Company's activities and reaffirmed the Company's expectations for fiscal year 2010.

"AmerisourceBergen continues to expect diluted earnings per share from continuing operations for fiscal year 2010 to be in a range of $1.89 to $1.98, which represents an increase of 12 percent to 17 percent over the $1.69 in fiscal year 2009," said Yost. "Also unchanged are our key assumptions supporting this diluted earnings per share range, which are: revenue growth of between 7 percent and 8 percent; operating margin expansion in the low to mid single digit basis point range; and free cash flow in the range of $500 million to $575 million, which includes capital expenditures in the $140 million range. Assumptions also include the expected repurchase of approximately $350 million of AmerisourceBergen common shares in fiscal 2010."
