               MCKESSON REPORTS FISCAL 2004 THIRD QUARTER RESULTS

- -     Revenues of $18.2 billion, up 22%.

- -     Excluding warehouse sales, revenues up 14% with Pharmaceutical Solutions
      revenues up 15%.

- -     Net income of $120.2 million, down 10%, and diluted EPS of 41 cents, down
      11%.

SAN FRANCISCO, JANUARY 22, 2004 - McKesson Corporation (NYSE: MCK) today
reported that revenues for the third quarter ended December 31, 2003, were $18.2
billion, an increase of 22% from $14.9 billion a year ago, including customer
warehouse sales of $5.8 billion, which increased 45% from $4.0 billion.
Excluding warehouse sales, revenues grew 14%, to $12.4 billion from $10.9
billion a year ago. Third quarter net income was $120.2 million, a decrease of
10% from $134.3 million a year ago, and diluted earnings per share was 41 cents,
a decrease of 11% from 46 cents.

CORPORATE OVERVIEW

      "McKesson continued to have strong revenue growth in the third quarter,
driven by U.S. and Canadian pharmaceutical distribution," said John H.
Hammergren, chairman and chief executive officer. "While we had several unusual
issues in the quarter, which we have now addressed, our earnings are primarily
being impacted by the continued evolution of our Pharmaceutical Solutions
business model. In response, we are working with manufacturers and customers to
ensure that McKesson will be appropriately compensated for the valuable services
we provide, and we continue to focus on improvements in our operating
efficiency. We are encouraged by the progress we are making on all fronts."

      McKesson's third-quarter results were impacted by a number of factors:

            -     An estimated $25 million pre-tax reduction to Pharmaceutical
                  Solutions operating profit resulting from shifts in the timing
                  of a significant number of pharmaceutical price increases
                  anticipated for the third quarter. These price increases have
                  now occurred and will improve fourth quarter results.

            -     A previously announced automation contracting change that will
                  delay an estimated $16 million in pre-tax Pharmaceutical
                  Solutions operating profit into future periods.

            -     A $19 million pre-tax charge in the Pharmaceutical Solutions
                  pharmacy outsourcing business resulting from $10 million in
                  losses from a fixed price contract that has since been
                  renegotiated and a $9 million bad debt provision.

            -     A $22 million pre-tax increase to Pharmaceutical Solutions
                  operating profit from the cash proceeds for the settlement of
                  an antitrust class action lawsuit brought against
                  manufacturers of a cardiac drug.

            -     A $20 million pre-tax contract charge in Information Solutions
                  international operations.

            -     An $8 million after-tax benefit resulting from certain income
                  tax settlements and adjustments.

      Additionally, Pharmaceutical Solutions operating profit was reduced by
fewer vendor buying opportunities in the third quarter compared to a year ago.
This continues a trend previously discussed in the second quarter.

      In the third quarter a year ago, McKesson's pre-tax income was reduced by
several factors netting to approximately $19 million: $51 million in estimated
contract losses for Information Solutions international operations, a $22
million credit for reversal of Information Solutions domestic customer
settlement reserves and $10 million in gains from the sale of Pharmaceutical
Solutions leases and equity investments.


                                       2

      "Looking ahead in Pharmaceutical Solutions, we are very pleased with our
new contract to supply the Department of Veterans' Affairs," said Hammergren.
"This agreement, combined with recently renewed agreements for major national
distribution customers such as Rite-Aid, Omnicare and Caremark, provides a
foundation for strong U.S. revenue growth throughout the next fiscal year."

      "This new contract and our contract renewals have been priced at
competitive rates designed to deliver our target returns. Improving returns
continues to be a corporate priority for shareholder value creation."

      "For our fourth quarter, Pharmaceutical Solutions revenues, excluding
warehouse sales, should grow about 13%. Warehouse sales growth should be above
35%. We expect a fourth-quarter decline of 20 to 25 basis points in operating
margin. That anticipated decline includes both the positive impact of the shift
in price increases from the third quarter to the fourth quarter, and the
continued negative impacts of the automation contracting change and fewer
product buying opportunities."

      "For fiscal 2005, Pharmaceutical Solutions revenue growth should be in the
mid to high teens, reflecting our new contracts and renewals. However, we expect
that operating margin will remain under near-term pressure as the business model
continues to evolve."

      "In Medical-Surgical Solutions, growth among alternate site customers
remains strong, helping offset the transition of the previously announced loss
of our largest acute care customer. Our operating improvement remains on
schedule and we are pleased with the progress we are continuing to make."

      "In Information Solutions, revenue growth was flat due primarily to
decreases in non-clinical software and outsourcing service revenues and the
impact of longer installation timelines required for certain large, complex
clinical implementations. In the fourth quarter, revenue growth should be up
modestly from last year's strong performance. Operating margin in the fourth
quarter should be up, in the range of 13 to 15%. This business continues to play
a key role in our One McKesson hospital strategy."

      Pharmaceutical Solutions revenue growth among institutional customers was
up strongly. Revenue growth from independent pharmacy customers continued to be
solid. Institutional customers accounted for 45% of U.S. pharmaceutical
distribution revenues, retail chains accounted for 34% and independent
pharmacies, 21%. Warehouse sales were up 45% due to several new agreements.

      McKesson Canada revenues increased 35% in the quarter. On a constant
currency basis, Canadian revenues would have increased 14%.

      Pharmaceutical Solutions operating profit was down 21%, driven by the
series of factors described above. During the third quarter a year ago,
Pharmaceutical Solutions recorded a $5.3 million gain on the sale of customer
lease receivables and a $4.5 million gain on the sale of venture investments.

      Medical-Surgical Solutions revenues were down 1%. Revenue growth was
strong among alternate site customers, especially physician offices, but was
negatively impacted by the start of the transition of the previously announced
loss of the segment's largest acute care customer. Operating profit of $22.3
million was up 27%, due to improved gross margins and lower operating costs.
Operating profit was reduced by a charge of $2.0 million to restructure the
medical-surgical distribution center network to mitigate the impact of the
customer loss.

      Information Solutions revenues were flat compared to the prior year.
Software revenues were down 9% to $56.2 million, primarily due to decreases in
non-clinical software and the longer installation period required for certain
large, complex clinical implementations, which has the effect of delaying
revenue recognition. Services revenues were up 3% to $211.6 million. Hardware
revenues were down 3% to $26.5 million.


                                       5

      Operating profit in the third quarter was reduced by the $20 million
charge for estimated contract losses in international operations. Last year's
third quarter included a net expense of $29 million reflecting the original $51
million charge for international contract losses, offset in part by the $22
million credit for the reversal of a portion of previously recorded reserves for
domestic customer settlements.

      McKesson used cash of $276 million in operations year to date compared to
generating $365 million in the first nine months a year ago. However, McKesson
had no accounts receivable sales in this year's third quarter compared to
accounts receivable sales of $900 million in the third quarter a year ago.

      The company's net debt to net capital ratio was 23.1% compared to 21.8% a
year ago. The financial statements and the net debt to net capital ratio have
been recast to effectively classify the company's trust convertible preferred
securities as debt in accordance with Financial Accounting Standards Board
Interpretation No. 46, "Consolidation of Variable Interest Entities."

      The company repurchased $40 million of common shares in the quarter,
completing a previously authorized $250 million share repurchase program. As
previously announced, the company's Board of Directors has authorized a new $250
million share repurchase program. At December 31, 2003, McKesson had 291.2
million shares outstanding.

      A Webcast of the company's regular conference call to review financial

(1)   As a result of the application of Financial Accounting Standards Board
      Interpretation No. 46, "Consolidation of Variable Interest Entities", the
      Company no longer consolidates its investment in the McKesson Financing
      Trust (the "Trust"). Accordingly, the Company now recognizes long-term
      debt issued to the Trust in lieu of the preferred securities that the
      Trust issued to third parties. Additionally, the consolidated financial
      statements include interest expense on the long-term debt issued to the
      Trust and no longer report dividends on the preferred securities, net of
      tax. These changes did not have a material impact on our consolidated
      financial statements, including diluted earnings per share.

      For the quarters and nine months ended December 31, 2003 and 2002,
      interest expense, net of related income taxes, of $1.5 million and $4.6
      million, has been added to net income for purposes of calculating diluted
      earnings per share. This adjustment reflects the impact of the Company's
      potentially dilutive obligations.

(2)   In September 2002, we sold a marketing fulfillment business, which was
      included in our Pharmaceutical Solutions segment. Financial results for
      this business have been presented as a discontinued operation.
