AmerisourceBergen Reports Record Operating Revenue and Cash Flow in Year-End Results; Company Expects Diluted Earnings Per Share of $3.95 to $4.25 for Fiscal 2006

November 3, 2005

VALLEY FORGE, Pa., Nov 03, 2005 (BUSINESS WIRE) -- AmerisourceBergen Corporation (NYSE:ABC) today reported results for its fiscal fourth quarter and year ended September 30, 2005. The following results are presented in accordance with U.S. generally accepted accounting principles (GAAP).

Fiscal Fourth Quarter Highlights

-- Diluted earnings per share from continuing operations of $0.20, including special charges of $0.75 related primarily to early debt retirement.

-- Record operating revenue of $13.0 billion, up 7 percent.

-- Record low interest expense of $9.4 million.

-- Low total debt to total capital ratio of 18.2 percent.

Fiscal Year Highlights

-- Diluted earnings per share from continuing operations of $2.73 before the cumulative effect of an accounting change, including net special charges of $0.60.

-- Record operating revenue of $50.0 billion, up 2 percent.

-- Record cash flow from operations of $1.53 billion.

"In the fiscal fourth quarter, excluding special charges, we delivered strong operating performance that represents positive momentum as we exit a challenging year and begin a promising fiscal 2006," said R. David Yost, AmerisourceBergen's Chief Executive Officer. "Our disciplined working capital management and timely refinancing has produced the strongest balance sheet in our history. The transition to a fee-for-service model with our branded pharmaceutical manufacturers is largely complete. We are enthusiastic about our future with increasing business opportunities including our recent entry into the Canadian market, completion of our new distribution network, continued expansion of generic usage, continuation of our specialty business's strong growth and our ability to leverage over time the added pharmaceutical utilization of the Medicare Modernization Act which begins in January 2006."

Discussion of Results

AmerisourceBergen's operating revenue was a record $13.0 billion in the fourth quarter of fiscal 2005 compared to $12.1 billion for the same period last year, a 7 percent increase. Bulk deliveries in the quarter decreased 23 percent to $953.5 million.

Consolidated operating income in the September quarter declined 11 percent to $155.0 million compared to the prior year's fourth quarter. A $12.0 million charge for facility consolidation and employee severance, most of which was for the outsourcing of information technology activities, negatively impacted operating income. An anticipated gain from an antitrust settlement was not received until October and will benefit operating income by approximately $15 million in the first quarter of fiscal 2006, although the gain is expected to be offset by facility consolidation and employee severance costs. In the September quarter of 2004, the facility consolidation and employee severance charge was $2.2 million.

During the fourth fiscal quarter, the Company successfully tendered for and retired its $500 million, 8.125 percent bonds due 2008 and its $300 million, 7.25 percent bonds due 2012, replacing them with two new bonds, a $400 million, seven-year bond with an effective rate of 5.71 percent and a 10-year, $500 million bond with an effective rate of 5.94 percent.

Interest expense in the fourth quarter of fiscal 2005 was a record low $9.4 million compared to $23.5 million in the prior year's fourth quarter, a 60 percent decrease driven by net debt reduction.

The effective tax rate for the fourth quarter of fiscal 2005 was 38.3 percent compared to 38.0 percent in the same quarter of the previous year. The tax rate applied to the early retirement of debt in fiscal 2005's fourth quarter was 36.1 percent as its costs are not deductible in certain states.

Diluted earnings per share from continuing operations for the fourth quarter of fiscal 2005 were $0.20 compared to $0.82 in the prior year's fourth quarter. Included in the fiscal 2005 fourth quarter results is a charge of $0.68 per diluted share, net of tax, related to the retirement of debt and a $0.07 per diluted share, net of tax, charge for facility consolidation and employee severance costs. The previous fiscal year's fourth quarter included a facility consolidation and employee severance charge of $0.01 per diluted share, net of tax.

Weighted average diluted shares outstanding for the fourth quarter of fiscal year 2005 were 104.8 million, a reduction from 117.0 million in the same period last year primarily due to the Company's share repurchase programs during the year.

Operating revenue in fiscal year 2005 increased 2 percent to a record $50.0 billion from $48.8 billion in the previous fiscal year. Bulk deliveries to customer warehouses were up 6 percent to $4.6 billion.

Consolidated operating income for fiscal 2005 decreased 29 percent to $636.9 million as gross profit declined and operating expenses increased for the fiscal year.

For the fiscal year ended September 30, 2005, diluted earnings per share from continuing operations were $2.73 before the cumulative effect of a change in accounting and included a net charge of $0.60, net of tax, for special items, which were primarily the costs related to the early retirement of debt, facility consolidations and employee severance and the gains from litigation settlements. Diluted earnings per share from continuing operations in fiscal 2004 were $4.12, which included a net benefit of $0.04 related to gains from litigation settlements, net the costs related to the early retirement of debt, facility consolidations and employee severance.

Cash generated from operations in fiscal 2005 was $1.53 billion compared to $825 million last fiscal year. The Company's total debt to total capital ratio was a low 18.2 percent.

"In the fourth quarter of fiscal 2005, the strong operating performance in pharmaceutical distribution overcame performance in PharMerica that was below our expectations," said Kurt J. Hilzinger, AmerisourceBergen's President and Chief Operating Officer.

"AmerisourceBergen Specialty Group continued to be a growth driver with annual operating revenue of more than $7 billion. Led by its market-leading oncology business, with strong performances in the plasma and reimbursement consulting businesses, the Group delivered outstanding growth in the quarter.

"In the Drug Corporation, our customer-focused Transform program continued to gain momentum in the quarter, and our generics program also was a significant contributor. Our Optimiz(R) program, which is designed to lower our operating costs, continued on schedule and on budget. In fiscal 2005, we opened new state-of-the-art facilities in Columbus, Dallas, and Chicago, and we consolidated six distribution centers for a total of 32 in the U.S. at the end of the fiscal year. In fiscal 2006, we opened our new Kansas City distribution center in October, 2005 and expect to open the final of our six new facilities in Bethlehem, Pennsylvania, in the spring. We expect to consolidate six facilities in fiscal 2006, bringing the number of distribution centers in our U.S. network to 28, and expect the total number of U.S. distribution centers to be in the mid-twenties by the end of fiscal 2007."

"In the fourth quarter, our PharMerica segment continued to face a difficult and competitive long-term care environment, especially around market pricing and government reimbursement. Although the market is beginning to present some opportunities with completion of the merger between the two other national long-term care institutional pharmacy companies, the challenges remaining in the move to Medicare Part D will make 2006 a transition year for PharMerica. Our expectation in fiscal 2006 is for mid single-digit revenue growth and slightly lower operating margins," said Hilzinger.

Segment Review

AmerisourceBergen operates in two segments: Pharmaceutical Distribution (which includes the operations of AmerisourceBergen Drug Corporation and the AmerisourceBergen Specialty, Packaging and Technology groups) and PharMerica (which includes the long-term care pharmacy and workers' compensation fulfillment businesses). Intersegment sales of $219.5 million in the fourth quarter of fiscal 2005 from AmerisourceBergen Drug Corporation to PharMerica, which are included in the Pharmaceutical Distribution segment operating revenue, are eliminated for consolidated reporting purposes.

Pharmaceutical Distribution Segment

Operating revenue in the fourth quarter of fiscal 2005 increased to a record $12.8 billion compared with $12.0 billion in the fourth quarter of fiscal year 2004, a 7 percent increase.

Pharmaceutical Distribution customer mix in the fourth quarter of fiscal 2005 was 59 percent institutional and 41 percent retail, reflecting strong growth in the Specialty Group.

For the segment, gross profit as a percentage of operating revenue in the fourth quarter of fiscal 2005 was 3.20 percent, compared to 3.12 percent in the same period in the prior fiscal year. Operating income as a percentage of operating revenue was 1.18 percent in the September quarter of fiscal 2005 compared with 1.20 percent in the prior fiscal year's September quarter. The Company recorded a LIFO credit of $15.0 million in the quarter, compared to a $27.4 million credit in the same quarter of the prior year, due to the significant reduction in inventory during the year. The positive impact of the credit was offset by losses from hurricanes Katrina and Rita as well as higher than average bad debt expense.

PharMerica

PharMerica's operating revenue for the fourth quarter of fiscal 2005 was $401.6 million, a 3 percent increase over the previous year's fourth quarter. Operating income for the same period was $15.9 million, compared to $33.8 million for the same quarter last year, which was favorably impacted by a $12 million reduction in sales and use tax expense.

Looking To Fiscal 2006

"For fiscal 2006, we expect diluted earnings per share to be between $3.95 and $4.25 and operating revenue growth to be in the range of 6 percent to 8 percent," said Yost. "Our earnings per share expectations include the impact of a $0.09 charge for equity compensation expense and the anticipation that litigation recovery gains will be offset by facility consolidation and employee severance expense. In the pharmaceutical distribution segment, we expect operating margins for fiscal 2006 to be in the range of 115 to 125 basis points. Cash flow from operations in fiscal 2006 is expected to be in the range of $500 million to $600 million."

                             (unaudited)


Basic earnings per share is computed on the basis of the weighted
average number of shares of common stock outstanding during the
periods presented. Diluted earnings per share is computed on the basis
of the weighted average number of shares of common stock outstanding
during the period plus the dilutive effect of stock options.
Additionally, the diluted earnings per share calculation considers the
convertible subordinated notes as if converted and, therefore, the
effect of interest expense related to those notes is added back to net
income in determining income from continuing operations available to
common stockholders.

                         CHANGE IN ACCOUNTING
                             (UNAUDITED)


Effective October 1, 2004, the Company changed its method of
recognizing cash discounts and other related manufacturer incentives.
The Company previously recognized cash discounts as a reduction of
cost of goods sold when earned, which was primarily upon payment of
vendor invoices. The Company now records cash discounts as a component
of inventory cost and recognizes such discounts as a reduction to cost
of goods sold upon the sale of the inventory. In connection with the
Company's transition to a fee-for-service model, the Company believes
the change in accounting method provides a more objectively
determinable method of recognizing cash discounts and a better
matching of inventory cost to revenue, as inventory turnover rates are
expected to continue to improve.

The Company recorded a $10.2 million cumulative effect of change in
accounting (net of tax of $6.3 million) in the consolidated statement
of operations for the fiscal year ended September 30, 2005. This $10.2
million cumulative effect adjustment reduced diluted earnings per
share by $0.09 for the fiscal year ended September 30, 2005. The
accounting change is incorporated in the Company's results for the
three months ended September 30, 2005, and the change decreased
earnings from continuing operations in the September quarter by
approximately $0.5 million, net of tax, and had no impact on diluted
earnings per share from continuing operations. The accounting change
improved earnings from continuing operations in the fiscal year ended
September 30, 2005 by approximately $11.5 million, net of tax, or
$0.11 per diluted share from continuing operations.


The pro forma effect of this accounting change on prior periods is as
follows:
