Amgen's Second Quarter 2005 Adjusted Earnings Per Share Increased 42 Percent to 88 Cents

THOUSAND OAKS, Calif.--(BUSINESS WIRE)--July 19, 2005--Amgen Inc. (NASDAQ:AMGN):

Amgen (NASDAQ:AMGN) reported adjusted earnings per share (EPS) for the second quarter of 2005 of 88 cents, an increase of 42 percent compared to 62 cents during the second quarter of 2004. Adjusted net income rose 36 percent to $1.1 billion compared to $809 million in the second quarter of 2004. The company also increased its full year guidance for total revenue growth to a range of mid-to-high teens from the previous range of low double-digits to mid-teens and for adjusted EPS to a range of $3.10 to $3.20 from the previous range of $2.80 to $2.90, which represents an increase of 29 to 33 percent over 2004 adjusted EPS.

During the second quarter, total product sales increased 26 percent to $3.1 billion from $2.4 billion in the second quarter of 2004. Second quarter U.S. sales totaled $2.5 billion, an increase of 26 percent versus the same quarter in 2004. International sales totaled $540 million versus $424 million during the comparable period in 2004, an increase of 27 percent. International sales benefited from foreign exchange by approximately $31 million. Total revenue increased 23 percent during the second quarter to $3.2 billion.

Adjusted earnings per share and adjusted net income for the three months ended June 30, 2005 and 2004 primarily exclude certain expenses related to the acquisitions of Immunex Corporation and Tularik Inc. These expenses and other items are itemized on the reconciliation tables below.

On a reported basis and calculated in accordance with U.S. generally accepted accounting principles (GAAP), Amgen's earnings per share increased 44 percent to 82 cents in the second quarter of 2005 from 57 cents in the same quarter last year. Net income was $1.0 billion in the second quarter of 2005 versus $748 million for the second quarter of 2004, an increase of 38 percent.

"Our strong business momentum continued well into the second quarter, which has enabled us to raise revenue and earnings guidance for the year," said Kevin Sharer, chairman and CEO. "Our pipeline continues to advance, which will be key to driving long-term growth," concluded Sharer.

Product Sales Performance

Worldwide sales of Aranesp® (darbepoetin alfa), increased 36 percent to $837 million in the second quarter of 2005 versus $617 million during the second quarter of 2004. This growth was driven principally by demand reflecting market share gains and to a lesser extent market growth. U.S. Aranesp sales were $536 million versus $380 million in the prior year, with share gains in all major segments driving growth. International Aranesp sales were $301 million versus $237 million in the same quarter last year. International Aranesp sales benefited from foreign exchange of approximately $17 million in the second quarter.

Sales of EPOGEN® (Epoetin alfa) during the second quarter were $647 million versus $633 million in the comparable period of 2004. EPOGEN sales increased by two percent in the second quarter of 2005 reflecting a decrease in demand that was offset by wholesaler inventory changes and a favorable revised estimate of dialysis demand (primarily spillover) for prior quarters. Demand was affected by higher sales incentives and increased usage of Aranesp in dialysis. Spillover is a result of the company's contractual relationship with Johnson & Johnson. (Please refer to the Company's 2004 Form 10-K for a more detailed discussion of this relationship and a description of spillover.)

Combined worldwide sales of Neulasta® (pegfilgrastim) and NEUPOGEN® (filgrastim), were $899 million in the second quarter of 2005 versus $721 million for the second quarter of 2004, an increase of 25 percent. Combined sales growth for Neulasta and NEUPOGEN was primarily driven by increased demand for Neulasta.

Combined sales of Neulasta and NEUPOGEN in the United States were $698 million in the second quarter of 2005 versus $557 million in the second quarter of 2004, an increase of 25 percent. Combined international sales increased 23 percent to $201 million in the second quarter of 2005 versus $164 million over the same quarter in the prior year. Combined international Neulasta and NEUPOGEN sales benefited from foreign exchange by approximately $11 million in the second quarter of 2005.

Sales of Enbrel® (etanercept), increased 45 percent during the second quarter to $639 million versus $440 million during the same period in 2004, driven by strong demand. ENBREL continues to lead the Dermatology biologic marketplace and its market share is stable in the competitive Rheumatology setting.

Operating Expense Analysis on an Adjusted Basis:

Cost of sales increased to $530 million in the second quarter of 2005 from $435 million during the second quarter of 2004, primarily due to higher sales volumes.

Research and development (R&D) expenses totaled $564 million during the second quarter versus $460 million in the second quarter of 2004. Second quarter increases were primarily driven by staff-related expenses in part related to the Tularik acquisition and key clinical trials including the ramp up of large-scale Phase 3 trials for AMG 162, Amgen's investigational therapy for bone loss.

Selling, general and administrative (SG&A) expenses were $646 million in the second quarter versus $587 million for the same quarter of the prior year. Increases for the second quarter are a result of higher staff-related expenses in support of the Company's key products and the Wyeth profit share related to ENBREL sales growth.

Amgen's adjusted tax rate decreased five percentage points compared to the second quarter of 2004 due to favorable resolution of prior year tax claims with the IRS and to a lesser degree, an increase in permanently reinvested earnings of its foreign subsidiaries. The favorable resolution of prior year tax claims benefited adjusted EPS by approximately 4 cents during the quarter. For the remainder of the year, the adjusted tax rate is expected to be slightly lower than the Company's first quarter 2005 adjusted rate of 26.4 percent.

Stock repurchases for the second quarter 2005 totaled $750 million representing approximately 12 million shares. In December 2004, the Company's board of directors authorized a stock repurchase program of $5 billion. At the end of the second quarter, the Company had $3.5 billion remaining under this stock authorization.

Capital expenditures for the second quarter of 2005 were $205 million, primarily due to construction at the company's Puerto Rico manufacturing facility, versus $356 million in 2004. The company's cash and marketable securities were $4.4 billion at the end of the quarter.

Second Quarter Product and Pipeline Highlights

AMG 162: During the second quarter, pivotal Phase 3 trials for AMG 162 completed enrollment in postmenopausal osteoporosis and treatment induced bone loss in non-metastatic breast cancer and prostate cancer.

Aranesp: Amgen announced the submission of a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) for Aranesp. The sBLA is based on Phase 3 data that Amgen believes will demonstrate Aranesp administered every three weeks is safe and effective in the treatment of chemotherapy-induced anemia in patients with non-myeloid malignancies.

New interim data for Aranesp suggesting a major response in anemic patients with myelodysplastic syndromes (MDS) was recently presented at the 17th International Symposium of the Multinational Association of Supportive Care in Cancer (MASCC) at Geneva. The data was generated from a Phase 2 study evaluating the use of 500 mcg of Aranesp every three weeks to treat anemia in patients with MDS.

Enbrel: During the quarter, the FDA approved an expanded indication for ENBREL to improve physical function in patients with psoriatic arthritis. ENBREL is the first and only treatment to receive this expanded indication.

Panitumumab: Amgen, together with its partner Abgenix, announced the initiation of a Phase 3 clinical study to evaluate the potential benefits of adding panitumumab, an experimental fully human antibody to bevacizumab (Avastin) and chemotherapy. The clinical trial called the PACCE (Panitumumab Advanced Colorectal Cancer Evaluation) study is a randomized, multi-center, open label study with endpoints of progression-free survival, overall survival and response rate.

AMG 531: Amgen is in the process of filing an IND in chemotherapy-induced thrombocytopenia (CIT) for AMG 531. Studies in CIT will begin in 2005.

Notes to Reconciliation of GAAP Earnings to "Adjusted" Earnings
(In millions, except per share data)
(Unaudited)

(1) To exclude the incremental compensation provided to certain
    Tularik Inc. ("Tularik") employees principally related to non-cash
    compensation expense associated with stock options assumed in
    connection with the acquisition and amounts payable under the
    Tularik short-term retention plan. The total estimated remaining
    costs of such incremental compensation is approximately $21
    million, pre-tax.

(2) To exclude the ongoing, non-cash amortization of acquired
    intangible assets, primarily Enbrel®, related to the Immunex
    Corporation ("Immunex") acquisition. The total 2005 annual
    non-cash charge is currently estimated to be approximately $347
    million, pre-tax.

(3) To exclude the impact of legal settlements incurred, net of
    amounts previously accrued, primarily related to settling a patent
    legal proceeding.

(4) To exclude the net gain realized on the termination of a
    manufacturing agreement with Genentech, Inc. ("Genentech") for the
    production of ENBREL at Genentech's manufacturing facility in
    South San Francisco.

(5) To exclude the incremental compensation payable to certain Immunex
    employees principally under the Immunex short-term retention plan.
    All amounts have been incurred under this plan.

(6) To exclude the pro rata portion of the debt issuance costs that
    were immediately charged to interest expense, as a result of
    certain holders of the convertible notes exercising their March 1,
    2005 put option and the related convertible notes being repaid in
    cash.

(7) To reflect the tax effect of the above adjustments.

(8) The following table presents the computations for GAAP and
    "Adjusted" diluted earnings per share computed under the treasury
    stock and the "if-converted" methods:

(A) On May 6, 2005, in connection with an exchange offer, we modified
    the terms of approximately 95% of our convertible notes then
    outstanding (the "Modified Convertible Notes"). As a result of
    certain of these modifications, if converted, the Modified
    Convertible Notes would be settled in 1) cash equal to the lesser
    of the accreted value of the Modified Convertible Notes at the
    conversion date or the conversion value, as defined, and 2) shares
    of common stock, if any, to the extent the conversion value
    exceeds the accreted value. Accordingly, the Modified Convertible
    Notes do not impact diluted earnings per share under the
    "if-converted" method but rather, they impact diluted earnings per
    share under the treasury stock method, and only to the extent that
    the conversion value exceeds the accreted value during any
    reporting period, requiring such difference, if any, to be
    potentially settled in shares of common stock.

(1) On March 2, 2005, as a result of certain holders of the
    Convertible notes exercising their March 1, 2005 put option, the
    Company repurchased $1,175 million, or approximately 40%, of the
    outstanding Convertible notes at their then-accreted value for
    cash. Accordingly the Convertible notes repurchased were
    classified as current liabilities at December 31, 2004.

(2) Holders of the remaining outstanding Convertible notes may require
    the Company to purchase all or a portion of the notes on specific
    dates as early as March 1, 2006 at the original issuance price
    plus accrued original issue discount through the purchase date.
    Accordingly, as of June 30, 2005, the Convertible notes have been
    classified as current liabilities.

Reconciliation of "Adjusted" Earnings Per Share Guidance to GAAP
Earnings Per Share Guidance for the Year Ended December 31, 2005

                                                             2005
                                                        --------------

"Adjusted" earnings per share guidance                  $3.10 - $3.20

Known adjustments to arrive at GAAP earnings:
  Amortization of acquired intangible assets (1)                (0.16)
  Tularik merger related incremental compensation (2)           (0.01)
  Write-off of convertible notes debt issuance costs (3)        (0.01)
  Legal settlements (4)                                         (0.02)
  Termination of manufacturing agreement (5)                     0.01
  Tax liability related to repatriation of certain
   foreign earnings (6)                                             -
                                                        --------------

GAAP earnings per share guidance                        $2.91 - $3.01
                                                        --------------


    The guidance for both "Adjusted" earnings per share and GAAP
    earnings per share does not include the impact of expense related
    to stock option compensation.

(1) To exclude the ongoing, non-cash amortization of acquired
    intangible assets, primarily Enbrel(R), related to the Immunex
    acquisition. The total 2005 annual non-cash charge is currently
    estimated to be approximately $347 million, pre-tax.

(2) To exclude the incremental compensation provided to certain
    Tularik employees principally related to non-cash compensation
    expense associated with stock options assumed in connection with
    the acquisition and amounts payable under the Tularik short-term
    retention plan.

(3) To exclude the pro rata portion of debt issuance costs that were
    immediately charged to interest expense, as a result of certain
    holders of the convertible notes exercising their March 1, 2005
    put option and the related convertible notes being repaid in cash.

(4) To exclude the impact of legal settlements incurred, net of
    amounts previously accrued, primarily related to settling a patent
    legal proceeding.

(5) To exclude the net gain realized on the termination of a
    manufacturing agreement with Genentech for the production of
    ENBREL at Genentech's manufacturing facility in South San
    Francisco.

(6) To exclude the tax liability related to the repatriation of
    certain foreign earnings under the American Jobs Act of 2004
    ("Jobs Act"). Uncertainty remains as to how to interpret numerous
    provisions of the Jobs Act. As such, we have not yet determined
    the amount of foreign earnings, if any, that will be repatriated
    and, therefore, the amount of the tax liability is not known.
    Based on our preliminary analysis to date, we are limited under
    the Jobs Act to repatriate up to approximately $500 million in
    foreign earnings.


    2004 adjusted earnings per share was $2.40 and a reconciliation to
    GAAP earnings per share for this amount was provided in our
    January 27, 2005 news release.
