     . Cost saving synergies captured ahead of schedule.

     . Consolidated seven distribution centers and two specialty operations.

     "This was an exceptional year at AmerisourceBergen," said R. David Yost,
AmerisourceBergen's Chief Executive Officer. "During fiscal 2002, we
successfully merged two great companies and created the industry leader in the
pharmaceutical supply channel; a Company with the scale and dedication to
maximize shareholder value, deliver the highest customer service, and provide
new and innovative solutions to suppliers and customers in the channel.



     "Our success is a reflection of the dedication and hard work of our
associates. They made it happen on the firing line. The financial result was a
more than 40 percent increase in earnings per share and $40 billion in revenue
for the year. Combined with our 25.5 percent ROCC, we exceeded our key financial
goals.

     "From the beginning, it has not been about being the biggest, but the best.
In one year, we have laid a solid foundation, and we have only begun to tap the
potential of AmerisourceBergen. With our number one position in the market, a
growing array of services and products, and a commitment to maximize our synergy
opportunities, we remain dedicated to increasing value for our shareholders,
customers, suppliers and associates." Discussion of Results

          AmeriSource Health Corporation and Bergen Brunswig Corporation merged
on August 29, 2001 to form AmerisourceBergen Corporation. Under purchase
accounting rules, AmerisourceBergen's fiscal 2002 fourth quarter and annual
results are compared with the fiscal 2001 historical fourth quarter and yearly
results which encompass the full year of former AmeriSource and approximately
one month of former Bergen. Pro forma data included in this news release refers
to the combined predecessor companies' operating results in the previous year's
fourth quarter and fiscal year, adjusted to eliminate amortization of goodwill
and merger-related special charges. Both former companies had the same fiscal
year ending September 30.

          Diluted earnings per share before special charges for the fourth
quarter of fiscal 2002 were $0.88, a 38 percent increase over the prior year's
fourth quarter. Income before special charges for the fourth quarter of fiscal
2002 increased to $97.3 million from $47.2 million in the same period last year.
Special charges, consisting of merger integration costs, were $2.3 million, net
of tax, in the quarter. Net income and diluted earnings per share for the
quarter were $95.0 million and $0.86, respectively.

          AmerisourceBergen's operating revenue, which excludes bulk deliveries
to customer warehouses, was $10.4 billion in the fourth quarter of fiscal 2002
compared to $5.5 billion for the same period last year. Fiscal 2002 fourth
quarter operating revenue increased 14 percent over fiscal 2001 fourth quarter
pro forma operating revenue of $9.1 billion.

          For the 2002 fiscal year, diluted earnings per share before special
charges were $3.29, a 42 percent increase over the prior year. Income before
special charges for the year increased to $359.6 million from $137.0 million
last year. Special charges, consisting of merger integration costs, were $14.6
million, net of tax, in fiscal year 2002. Operating revenue for the fiscal year

                                                                               2



ended September 30, 2002 was $40.2 billion compared to $15.8 billion in the
prior year, and represents a 16 percent increase over pro forma operating
revenue of $34.6 billion in fiscal year 2001. Net income and diluted earnings
per share for the 2002 fiscal year were $344.9 million and $3.16, respectively.

          The following discussion of results, including segment data, does not
include the impact of special charges.

          "In the fiscal 2002 fourth quarter, our outstanding performance was
driven by our continual focus on customer service, synergy cost savings ahead of
internal expectations, and strong working capital management," said Kurt J.
Hilzinger, AmerisourceBergen President and Chief Operating Officer. "The result
was a double digit expansion in operating margin, record earnings per share and
a ROCC of 25.5 percent.

          "In pharmaceutical distribution we consolidated four distribution
centers in the September quarter bringing the total number of consolidations in
the fiscal year to seven, in line with the schedule we set at the beginning of
the fiscal year. Our new generic pharmaceutical program, PROGenerics(TM), also
contributed to the quarter's strong performance.

          "With the integration of the key functional areas now nearly complete,
in fiscal 2003 we will continue to work toward building our new distribution
network and introducing new offerings to our customers in the pharmaceutical
supply channel. We expect to consolidate six larger distribution centers in the
coming fiscal year as well as begin building a number of new facilities and
expanding others. Retail and institutional customers will see new programs to
solve challenges such as staffing shortages, cost constraints and dispensing
accuracy.

          "In our PharMerica segment, strong revenue growth in the fiscal 2002
fourth quarter of 14 percent, pro forma, reflects continued solid performance by
PharMerica's workers' compensation business, as well as improved growth in the
long-term care business," said Hilzinger. "The favorable impact of a single
information technology platform, continued receivable and operating discipline,
and the positive impact of the new generic pharmaceutical program, drove
PharMerica's performance in the quarter."

Segment Review

          AmerisourceBergen operates in two segments: Pharmaceutical
Distribution (which includes the AmerisourceBergen Drug Company and
AmerisourceBergen Specialty Group operations) and PharMerica (which includes the
institutional pharmacy and workers'

                                                                               3



compensation fulfillment businesses). Intersegment sales of $201.2 million in
the fourth quarter of fiscal 2002 from AmerisourceBergen Drug Company 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 2002 increased to
$10.2 billion compared with $5.5 billion in the previous year's fourth quarter.
Operating revenue increased 14 percent over fiscal 2001 fourth quarter pro forma
revenue of $8.9 billion.

          Pharmaceutical Distribution customer mix in the fourth quarter of
fiscal 2002 was 54 percent institutional and 46 percent retail, and for fiscal
year 2002 the mix was 53 percent institutional and 47 percent retail. Both
customer groups had double-digit growth in the quarter and year.

          Operating income was $174.6 million in the fourth quarter of fiscal
2002, up from $94.8 million for the same quarter last year, and improved 22
percent compared to pro forma operating income of $143.2 million in the same
period last year. For the fiscal 2002 fourth quarter, operating income as a
percentage of operating revenue was 1.72 percent, an 11 basis point improvement
from the prior year's fourth quarter on a pro forma basis. Lower gross margins,
which reflect the Company's customer mix and the competitive environment, were
more than offset by lower total operating expenses as a percentage of operating
revenue.

          Total operating expenses as a percentage of operating revenue in the
fiscal 2002 fourth quarter were 2.20 percent, a 31 basis point improvement over
the same quarter last year on a pro forma basis driven by synergy cost savings,
customer mix and operating leverage.

          AmerisourceBergen Specialty Group, with annualized revenue of more
than $2.5 billion, continued its strong quarterly performance, building
significant positions in oncology, blood plasma, injectables and vaccine
distribution as well as growing its manufacturing services business.

PharMerica

          PharMerica's operating revenue for the fourth quarter of fiscal 2002
increased to $386.1 million from $116.7 million in the previous year's fourth
quarter. Operating revenue in the quarter increased 14 percent over pro forma
operating revenue of $338.1 million in the same period last year.

                                                                               4



          Operating income for the fourth quarter of fiscal 2002 was $22.9
million up from $6.5 million for the same quarter last year, and improved 22
percent over the prior year's pro forma fourth quarter operating income of $18.7
million. Operating income as a percentage of operating revenue increased 40
basis points in the quarter ended September 30, 2002 to 5.92 percent from 5.52
percent on a pro forma basis in the prior year.

Looking Ahead

          "For fiscal 2003, we expect another year of strong performance with
earnings per share growth of 20 percent excluding special charges, ROCC well
ahead of our 20 percent long-term target, and revenue growth in line with
projected market growth of 11 percent to 14 percent," said Yost. "We remain
confident in our ability to achieve annual cost saving synergies of $150 million
by the end of fiscal year 2004, followed by additional synergy capture through
completion of our distribution network."

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 available to common stockholders.

Pro Forma Information

The historical consolidated financial summary and summary segment information
for the three-months and year ended September 30, 2001, included in this press
release, reflect only the results of AmeriSource Health Corporation, as
predecessor to the Company, through August 29, 2001 and the results of
AmerisourceBergen Corporation for the period from August 29, 2001 through
September 30, 2001 (collectively, the "Historical Results"). In order to enhance
comparability, the following schedules as well as the summary segment
information include fiscal 2001 financial data on a pro forma basis. Within
these schedules, pro forma refers to the Historical Results combined with the
results of Bergen Brunswig Corporation through August 29, 2001. The pro forma
information for fiscal 2001 has not been prepared in accordance with generally
accepted accounting principles and does not represent consolidated results as if
the merger had occurred at the beginning of the periods presented. To enhance
comparability of financial information between fiscal years, the pro forma
information for fiscal 2001 excludes the amortization of goodwill and special
items related to the merger and environmental remediation and reflects the full
allocation of Bergen Brunswig Corporation's former Corporate segment to the
Pharmaceutical Distribution and PharMerica segments. The pro forma information
is not necessarily indicative of the actual results which might have occurred
had the operations and management of AmeriSource Health Corporation and Bergen
Brunswig Corporation been combined at the beginning of fiscal 2001.
