AmerisourceBergen Announces Refinancing of Its Senior Notes, Followed by Expansion of Its Share Repurchase Program to $750 Million

August 25, 2005

VALLEY FORGE, Pa.--(BUSINESS WIRE)--Aug. 25, 2005--AmerisourceBergen Corporation (NYSE:ABC) announced that today it is commencing a cash tender offer for its $500 million 8.125 percent senior notes due in 2008 and its $300 million 7.25 percent senior notes due in 2012, which the Company intends to finance with the proceeds of a private placement of debt. Further, provided the tender is completed, the Company's Board of Directors has authorized an increase to the amount available under its current common stock repurchase program to a total availability of $750 million.

"Successful refinancing of our current senior notes will increase our financial flexibility by allowing AmerisourceBergen to obtain long-term, lower interest rates and improved terms," said R. David Yost, AmerisourceBergen's Chief Executive Officer. "Repurchasing our shares reflects AmerisourceBergen's strong cash position."

Michael D. DiCandilo, AmerisourceBergen's Executive Vice President and Chief Financial Officer said, "With long-term interest rates at historically low levels, this is an opportune time to refinance these notes and lower our interest expense for the future.

"Excluding the anticipated refinancing charge of approximately $70 million after-tax related to the tender offer premium and the write-off of unamortized deferred financing costs, our diluted earnings per share expectations for fiscal 2005 remain unchanged. Those expectations are diluted earnings per share from continuing operations before the cumulative effect of an accounting change of between $3.30 and $3.50 on a GAAP basis.

"We continue to estimate that diluted earnings per share in fiscal 2006 will be between $3.60 and $4.40, on a GAAP basis. We are currently in the middle of our extensive annual planning process, and we expect to update our guidance for fiscal year 2006 in early November, when we announce results for fiscal year 2005."

The cash tender offer is for any and all $500 million of AmerisourceBergen's outstanding 8.125 percent senior notes due 2008 (CUSIP No. 03073QAB4) and any and all $300 million of its outstanding 7.25 percent senior notes due 2012 (CUSIP No. 03073EAB1) and includes a solicitation of consents to eliminate certain restrictive covenants from the indentures governing the notes. The offer is also conditioned on, among other things, the execution of financing for the cash tender price.

The offer and consent solicitation are being made pursuant to an Offer to Purchase and Consent Solicitation Statement dated August 25, 2005. The total consideration will be determined by pricing both notes, using standard market practice, to the maturity dates at a fixed spread of 50 basis points over the bid side yield on the 4.125 percent U.S. Treasury Note due August 15, 2008 for the 8.125 percent notes and a fixed spread of 50 basis points over the bid side yield on the 4.00 percent U.S. Treasury Note due November 15, 2012 for the 7.25 percent notes, determined at 2:00 p.m. Eastern Daylight Time on the business day immediately following the consent date, which the Company expects to be September 8, 2005, by reference to the Bloomberg Government Pricing Monitor. Holders who tender and deliver their consents to the proposed amendments to the indenture governing the notes by 5:00 p.m. Eastern Daylight Time on September 8, 2005 will be eligible to receive the total consideration, which includes a consent payment equal to $30 per $1,000 principal amount of notes tendered. Holders who tender after the consent date but by 5:00 p.m. Eastern Daylight Time on September 23, 2005 will be eligible to receive the tender offer consideration, which equals the total consideration less the consent payment. The offer and consent solicitation are subject to, and conditioned upon, the satisfaction or, where applicable, waiver of certain conditions, as described in the Offer to Purchase and Consent Solicitation Statement. There can be no assurance that any of such conditions will be met.

Lehman Brothers Inc. is the Dealer Manager and Solicitation Agent, and D.F. King & Co., Inc. is the Information Agent, in connection with the offer and consent solicitation. Requests for information should be directed to Lehman Brothers Inc. at (212) 528-7581 (call collect) or (800) 438-3242 (toll free). Requests for documents should be directed to D.F.

The offer and consent solicitation are being made solely by the Offer to Purchase and Consent Solicitation Statement.

Subject to completion of the tender offer and the related debt financing, the AmerisourceBergen Board of Directors has authorized an increase in the current stock repurchase program begun in May to a total availability of $750 million. The Company currently has used $94 million of the initial $450 million authorization and would add $394 million to the program.
