THOUSAND OAKS, Calif., Oct. 22 /PRNewswire-FirstCall/ -- Amgen (Nasdaq: AMGN) reported adjusted earnings per share (EPS), excluding stock option expense and certain other expenses, of $1.23 for the third quarter of 2008, an increase of 14 percent compared to $1.08 for the third quarter of 2007. Adjusted net income, excluding stock option expense and certain other expenses, increased 11 percent to $1,308 million in the third quarter of 2008 compared to $1,181 million in the third quarter of 2007. Stock option expense on a per share basis totaled 2 cents for both the third quarter of 2008 and the third quarter of 2007.

Total revenue increased 7 percent during the third quarter of 2008 to $3,875 million versus $3,611 million in the third quarter of 2007.

Adjusted EPS and adjusted net income for the third quarter 2008 and 2007 exclude, for the applicable periods, stock option expense, certain expenses related to acquisitions, restructuring charges and certain other items. These expenses and other items are itemized on the attached reconciliation tables. Adjusted EPS including the impact of stock option expense are also itemized in the notes to the attached reconciliation tables.

Calculated in accordance with United States (U.S.) Generally Accepted Accounting Principles (GAAP), Amgen's GAAP EPS were $1.09 in the third quarter of 2008 compared to $0.18 in the same quarter last year. GAAP net income was $1,158 million in the third quarter of 2008 compared to $201 million in the third quarter of 2007. GAAP reported results for the third quarter of 2007 were negatively impacted by the write-offs of $590 million of acquired in-process research and development related to the acquisitions of Alantos Pharmaceutical Holdings, Inc. and Ilypsa, Inc. as well as $293 million of charges related to the previously announced restructuring plan.

"Our financial results for the third quarter demonstrate strong operating performance and we are increasing our 2008 annual guidance," said Kevin Sharer, chairman and chief executive officer. "We are now focused on plans to commercialize denosumab in post-menopausal osteoporosis. We're excited about the opportunity to bring this novel treatment option to patients with this serious disease," concluded Sharer.

Product Sales Performance

During the third quarter, total product sales increased 7 percent to $3,784 million from $3,524 million in the third quarter of 2007. Sales in the U.S. totaled $2,929 million, an increase of 4 percent versus $2,809 million in the third quarter of 2007. International sales increased 20 percent to $855 million versus $715 million for the third quarter of 2007. Changes in foreign exchange positively impacted third quarter 2008 sales by $78 million. Excluding the impact of foreign exchange, total product sales increased 5 percent and international product sales increased 9 percent.

Worldwide sales of Aranesp(R) (darbepoetin alfa) increased 3 percent to $845 million in the third quarter of 2008 versus $818 million during the third quarter of 2007. In the U.S., third quarter 2008 Aranesp sales were relatively unchanged at $458 million in the third quarter of 2008 versus $460 million in the third quarter of 2007. U.S. sales of Aranesp in the third quarter of 2008 benefited from a $54 million change in the accounting estimate related to product sales return reserves. Excluding the positive impact of this change in the accounting estimate, U.S. sales of Aranesp decreased 12 percent in the third quarter of 2008 versus the prior year. The decline in U.S. Aranesp sales reflects the negative impact on demand, primarily in the supportive cancer care setting, from regulatory and reimbursement changes which principally occurred in the second half of 2007, and additional product label changes which occurred in the third quarter of 2008. The decline in demand in the third quarter of 2008 was slightly offset by an increase in the average net sales price. International Aranesp sales increased 8 percent to $387 million versus $358 million in the third quarter of 2007 due to changes in foreign exchange which positively impacted third quarter 2008 sales by approximately $35 million, partially offset by pricing pressure and ESA (erythropoiesis stimulating agent) dosing conservatism versus the prior year. Excluding the impact of foreign exchange, international product sales decreased 2 percent. Excluding the positive change in the accounting estimate related to product sales return reserves and foreign exchange gains, worldwide product sales decreased 8 percent in the third quarter of 2008 versus the prior year.

Sales of EPOGEN(R) (Epoetin alfa) increased 5 percent to $634 million in the third quarter of 2008 versus $602 million in the third quarter of 2007, primarily due to an increase in the average net sales price, favorable changes in wholesaler inventory levels and revised estimates of dialysis demand (primarily spillover) for prior quarters. Increased demand due to patient population growth was offset by a decline in dose / utilization within certain settings. Spillover is a result of the Company's contractual relationship with Johnson & Johnson. (Please refer to the Company's Form 10-K for a more detailed discussion of this relationship and a description of spillover).

Combined worldwide sales of Neulasta(R) (pegfilgrastim) and NEUPOGEN(R) (Filgrastim) increased 8 percent to $1,192 million in the third quarter of 2008 versus $1,100 million for the third quarter of 2007, driven primarily by increased demand for Neulasta. Combined sales of Neulasta and NEUPOGEN in the U.S. were $856 million in the third quarter of 2008 versus $830 million in the third quarter of 2007, an increase of 3 percent primarily reflecting an increase in demand for Neulasta. This increase in demand was driven by an increase in the average net sales price, partially offset by a decline in units sold, which we believe was primarily due to customer stocking which occurred in the second quarter of 2008. Combined international sales increased 24 percent to $336 million in the third quarter of 2008 versus $270 million for the same quarter in the prior year. This growth reflects changes in foreign exchange which positively impacted third quarter 2008 combined international sales by approximately $33 million, as well as increased demand driven by the continued conversion from NEUPOGEN to Neulasta. Excluding the impact of foreign exchange, combined worldwide product sales increased 5 percent and international product sales increased 12 percent.

Sales of Enbrel(R) (etanercept) increased 9 percent in the third quarter to $893 million versus $821 million during the same period in 2007. Sales growth was driven by higher demand due to increases in both average net sales price and patients. ENBREL sales growth in the third quarter was affected by share declines in the U.S. versus the third quarter of 2007 due to increased competitive activity. However, sales growth continued in both rheumatology and dermatology, and ENBREL continues to maintain a leading position in both segments.

Worldwide sales of Sensipar(R) (cinacalcet) increased 32 percent to $161 million in the third quarter of 2008 versus $122 million during the third quarter of 2007. This growth was principally driven by demand, primarily due to segment penetration.

Vectibix(R) (panitumumab) sales for the third quarter were unchanged year over year at $41 million.

Operating Expense Analysis on an Adjusted Basis:

Cost of sales increased 1 percent to $590 million in the third quarter of 2008 versus $585 million in the third quarter of 2007. This increase was due to higher sales volume offset by lower excess inventory write-offs, lower excess capacity charges and lower cost ENBREL. The Company now expects full year 2008 adjusted Cost of Sales expense as a percent of sales to be approximately 15 percent.

Research & Development (R&D) expenses were relatively unchanged at $700 million in the third quarter of 2008 versus $699 million in the third quarter of 2007. Higher staff-related costs as well as clinical trial spend for our emerging pipeline were offset by lower clinical trial costs for our denosumab registrational studies due to completion of enrollment and the benefit derived from our licensing transaction with Takeda in Japan. The Company now expects full year 2008 adjusted R&D expense dollars to be slightly lower than 2007. Consistent with historical spending patterns, the Company expects an increase in the fourth quarter versus the third quarter that should be similar in magnitude to the increase in 2007, though actual results may vary depending on licensing activities and pipeline progress.

Selling, General & Administrative (SG&A) expenses increased 11 percent to $890 million in the third quarter of 2008 versus $804 million in the third quarter of 2007 reflecting higher Wyeth profit share expenses and staff-related costs offset by lower litigation expense. Wyeth profit share expenses increased 22 percent to $298 million in the third quarter of 2008 versus $245 million in the third quarter of 2007. The Company still expects Wyeth profit share to be one third of adjusted SG&A expenses for the full year 2008. Excluding Wyeth profit share, adjusted SG&A expenses in the third quarter of 2008 increased 6 percent versus the same quarter last year. As in the past, adjusted SG&A expenses are expected to increase in the fourth quarter versus the third quarter. The Company still expects 2008 adjusted SG&A expense dollars excluding Wyeth profit share expenses to be slightly higher versus 2007.

The Company still expects the full year 2008 adjusted tax rate to be similar to 2007 as the federal R&D credit has been retroactively extended in the fourth quarter of 2008.

Average diluted shares for adjusted EPS in the third quarter of 2008 were 1,063 million versus 1,089 million in the third quarter of 2007. The Company currently has $4.9 billion remaining under its authorized stock repurchase program.

Capital expenditures for the third quarter of 2008 were approximately $159 million versus $306 million in the third quarter of 2007. The Company now expects full year 2008 capital expenditures to be approximately $750 million. Worldwide cash and marketable securities were $9.8 billion and debt was $11.2 billion at the end of the third quarter of 2008.

2008 Revenue and EPS Guidance Raised

The Company is raising its revenue guidance range from the previously provided range of $14.6 billion to $14.9 billion to an increased range of $14.9 billion to $15.2 billion. The Company is also raising its 2008 adjusted EPS guidance range from the prior range of $4.25 to $4.45 to an increased range of $4.45 to $4.55, excluding stock option expense and certain other expenses, based upon sales momentum and lower operating expense due to continuing efficiencies.

Third Quarter Product and Pipeline Update

The Company provided updates on selected products and late-stage clinical programs.

Denosumab: The Company presented full data results from its pivotal Phase 3 fracture study (FREEDOM) at the 2008 American Society of Bone and Mineral Research (ASBMR) Annual Meeting in Montreal. The study met the primary and all secondary end points.

Nplate (TM) (romiplostim): The Company noted that the U.S. Food and Drug Administration (FDA) has approved Nplate, the first and only agent that acts directly to increase platelet production for the treatment of thrombocytopenia in splenectomized (spleen removed) and non-splenectomized adults with chronic immune thrombocytopenic purpura (ITP). Nplate, the first FDA-approved peptibody protein, works by raising and sustaining platelet counts, representing a novel approach for the treatment of this chronic disease.

Nplate was also approved for ITP by Australia's Therapeutic Goods Administration (TGA) in July 2008. Amgen has filed for regulatory approval of Nplate in the European Union (EU), Canada, and Switzerland and these applications are currently under review.

AMG 317: The Company announced that it has reviewed interim results from a phase 2 study of AMG 317 in patients with moderate to severe asthma. The data showed evidence of biological activity; however, the clinical efficacy from the interim analysis did not meet expectations. The phase 2 study will be completed this year and results will be submitted to an appropriate peer-reviewed forum.

Forward-Looking Statements

This news release contains forward-looking statements that involve significant risks and uncertainties, including those discussed below and others that can be found in our Form 10-K for the year ended Dec. 31, 2007, and in our periodic reports on Form 10-Q and Form 8-K. Amgen is providing this information as of the date of this news release and does not undertake any obligation to update any forward-looking statements contained in this document as a result of new information, future events or otherwise.

No forward-looking statement can be guaranteed and actual results may differ materially from those we project. The Company's results may be affected by our ability to successfully market both new and existing products domestically and internationally, clinical and regulatory developments (domestic or foreign) involving current and future products, sales growth of recently launched products, competition from other products (domestic or foreign) and difficulties or delays in manufacturing our products. In addition, sales of our products are affected by reimbursement policies imposed by third-party payors, including governments, private insurance plans and managed care providers and may be affected by regulatory, clinical and guideline developments and domestic and international trends toward managed care and health care cost containment as well as U.S. legislation affecting pharmaceutical pricing and reimbursement. Government and others' regulations and reimbursement policies may affect the development, usage and pricing of our products. Furthermore, our research, testing, pricing, marketing and other operations are subject to extensive regulation by domestic and foreign government regulatory authorities. We or others could identify safety, side effects or manufacturing problems with our products after they are on the market. Our business may be impacted by government investigations, litigation and product liability claims. Further, while we routinely obtain patents for our products and technology, the protection offered by our patents and patent applications may be challenged, invalidated or circumvented by our competitors. We depend on third parties for a significant portion of our manufacturing capacity for the supply of certain of our current and future products and limits on supply may constrain sales of certain of our current products and product candidate development. In addition, we compete with other companies with respect to some of our marketed products as well as for the discovery and development of new products. Discovery or identification of new product candidates cannot be guaranteed and movement from concept to product is uncertain; consequently, there can be no guarantee that any particular product candidate will be successful and become a commercial product. Further, some raw materials, medical devices and component parts for our products are supplied by sole third-party suppliers.

    (In millions, except per share data)
    (Unaudited)

    (a) To exclude the impact of stock option expense recorded in accordance

        SFAS No. 123R was $25 million and $42 million, respectively, and $77
        million and $140 million, respectively.

        "Adjusted" diluted EPS including the impact of stock option expense
        for the three and nine months ended September 30, 2008 and 2007 was
        as follows:

    (b) To exclude the write-off of inventory resulting from a strategic
        decision to change manufacturing processes.

    (c) To exclude the ongoing, non-cash amortization of the R&D technology
        intangible assets acquired with the acquisitions of Abgenix, Inc.
        ("Abgenix") and Avidia, Inc. ("Avidia").

    (d) To exclude the ongoing, non-cash amortization of acquired product
        technology rights, primarily ENBREL, related to the Immunex
        Corporation ("Immunex") acquisition.

    (e) To exclude the following restructuring (expenses)/recoveries
        associated with our restructuring plan announced in August 2007, as
        follows (in millions):

      (1) Severance and other separation costs, partially offset in 2007 by
          the reversal of previously accrued expenses for bonuses and
          stock-based compensation awards, which were forfeited as a result of
          the employees' termination.

      (2) Asset impairment charges incurred in connection with the
          rationalization of our worldwide manufacturing operations in order
          to gain cost efficiencies and, to a lesser degree, the moderation of
          the expansion of our R&D facilities.

      (3) Accelerated depreciation resulting from our decision to accelerate
          the closure of one of our ENBREL commercial bulk production
          operations in connection with the rationalization of our worldwide
          network of manufacturing facilities.  The amount included above
          represents the excess of accelerated depreciation expense over the
          depreciation that would otherwise have been recorded if there were
          no plans to accelerate the closure of this manufacturing operation.

      (4) To exclude, from Other charges, loss accruals for leases
          principally related to certain facilities that will not be used in
          our business. Also, to exclude from SG&A in 2007, the cost
          recoveries for certain restructuring expenses, principally with
          respect to accelerated depreciation in connection with our
          co-promotion agreement with Wyeth.

    (f) To exclude loss accruals for settlements of certain commercial legal
        proceedings.

    (g) To exclude the loss accrual on the sale of certain less
        significant marketed products and related assets.

    (h) To exclude the write-off of inventory principally due to changing
        regulatory and reimbursement environments.

    (i) To exclude, for the applicable periods, merger related expenses
        incurred due to the Alantos Pharmaceutical Holding, Inc. ("Alantos"),
        Ilypsa, Inc. ("Ilypsa"), and Tularik Inc. acquisitions, primarily
        related to incremental costs associated with retention. Substantially
        all related amounts have been incurred.

    (j) To exclude the non-cash expense associated with writing-off the
        acquired in-process research and development ("IPR&D") related to the
        acquisitions of Alantos and Ilypsa in 2007.

    (k) To exclude the impairment of a non-ENBREL related intangible asset
        previously acquired in the Immunex acquisition.

    (l) To exclude the impact of writing-off the cost of a semi-completed
        manufacturing asset that will not be used due to a change in
        manufacturing strategy.

    (m) To exclude merger related expenses incurred due to the Abgenix
        acquisition, primarily related to incremental costs associated with
        recording inventory acquired at fair value which is in excess of our
        manufacturing cost.

    (n) To exclude the pro rata portion of the deferred financing and related
        costs that were immediately charged to interest expense as a result of
        certain holders of our convertible notes due in 2032 exercising their
        March 1, 2007 put option and the related convertible notes being
        repaid in cash.

    (o) To reflect the tax effect of the above adjustments for 2008, excluding
        (1) certain components of the write-off of inventory (see (b) above),
        (2) certain of the restructuring charges (see (e) above), (3) certain
        of the loss accruals for settlements of commercial legal proceedings
        (see (f) above) and (4) certain components of the loss accrual on the
        sale of certain less significant marketed products and related assets
        (see (g) above).

    (p) To exclude the income tax benefit recognized as the result of
        resolving certain non-routine transfer pricing issues with the
        Internal Revenue Service ("IRS") for prior periods.

    (q) To reflect the tax effect of the above adjustments for 2007, excluding
        (1) certain of the restructuring charges (see(e) above), (2) certain
        components of the write-off of inventory (see (h) above), (3) the
        write-off of the acquired IPR&D related to the Alantos and Ilypsa
        acquisitions (see (j) above), (4) the write-off of the cost of a
        semi-completed manufacturing asset (see (l) above), and (5) the tax
        benefit recognized as a result of resolving certain non-routine
        transfer pricing issues with the IRS (see (p) above).
